African dryland farming systems integrate crop and livestock production. In these systems, cropland and livestock productivities are intricately connected to support livelihoods of pastoral and agropastoral communities inhabiting African drylands. However, achieving sustainable increases in crop and livestock production under the prevailing conditions of low external inputs, soil degradation and climate variability and vulnerability to climate change, remains a great challenge in African drylands. Thus, to address these inherent challenges and achieve food security in the region, there is a need to adopt sustainable agricultural systems and practices. Pasture cropping, a no-tillage system where annual cereal crops are sown into perennial pastures during their dormant stage, has great potential to diversify African dryland farming systems and enhance overall cropland productivity. This can be linked to its contribution to increased perennial vegetation cover that protects the soil from agents of erosion, improving soil structure and soil hydrological properties, accumulation of organic matter, reducing N leaching, promoting C sequestration and weed control. Despite its great potential, pasture cropping in African drylands is still at its infancy stage. This review examines the potential of pasture cropping as a sustainable agricultural production system in African drylands. Specifically, we describe its salient features, benefits and challenges and explore its applicability to the environmental and socio-economic conditions of African drylands. Pasture cropping shows promise for improving agricultural productivity and sustainability in the African drylands. However, to achieve its full potential, significant adaptations are needed to tailor the system to match prevailing local socio-economic and environmental conditions, including climate and local adaptation, species selection, socio-economic constraints and economic viability among farming communities.
Using Côte d’Ivoire as a case study, this article examines how the abolition of forced labor in the French colonies of Africa in 1946 put statistics at the heart of tensions between the colonial administration, European planters, and African planters. The first section suggests that figures were instrumentalized to serve competing group interests: on one side, those of European planters eager to show the iniquity of the measure to abolish forced labor, which undermined their economic activities due to the resulting labor shortages; on the other side, those of Ivorian planters, who produced figures to argue for the rights of workers and to convince the colonial administration of the need to move toward a system of freedom of labor. The article thus puts the focus on a blind spot in the academic literature, namely, the role of African agency in the production of figures and their capacity to resist colonial domination. It also examines how West African workers managed to circumvent the colonial recruiting system that had been set up by European planters in the form of the Syndicat interprofessionnel d’acheminement de la main-d’œuvre (Interprofessional union for the transport of labor, or SIAMO). It is this in particular that leads me to question the data produced by SIAMO, which attempted to direct migrant workers toward European farms in the south from 1950 onward.
Human immunodeficiency virus (HIV) and mental health have complex, bidirectional impacts. Integrated service delivery, especially in low- and middle-income countries (LMICs) where resources are most limited and the burden of HIV is heaviest, may help to improve both HIV and mental health outcomes. While the integration of mental health and HIV services has been studied in various settings, previous reviews on this topic have primarily focused on the integration processes rather than health outcomes. In this systematic review, we evaluated the effectiveness of interventions in LMICs that integrated mental health and HIV services. We searched PubMed, CINAHL, Sociological Abstracts, PsycINFO and EMBASE and conducted backward and forward citation searches. We included studies conducted in LMICs that evaluated the integration of services for HIV and mental health conditions using pre-post or multi-arm study designs, published in a peer-reviewed journal from January 2000 through January 2024. Studies on substance use services were excluded. Risk of bias for included studies was assessed using the Evidence Project tool. We summarized findings narratively, including both mental health-related and HIV-related outcomes. Eighteen studies with a total of 9,729 participants were included in the analysis, among which 17 studies were conducted in sub-Saharan Africa and 10 were randomized controlled trials. Seventeen studies used a task-sharing approach, where nonspecialists provided mental health interventions. The low follow-up rate and lack of random participant selection suggested the increased risk of bias in most studies. Overall, interventions that integrated mental health and HIV services provided greater improvement in recipients’ mental health symptoms (e.g., depression and post-traumatic stress disorder) than HIV services alone, often reducing symptom scores by more than 50%. While the evidence on HIV-related outcomes (e.g., antiretroviral therapy adherence, viral suppression and HIV stigma) was more limited, most studies that reported these outcomes showed positive effects of integrated interventions, especially community-based ones. These findings suggest the benefit of the interventions that integrate mental health and HIV services in LMICs, although further evaluations are warranted.
Against the backdrop of debates about migrant integration in Western countries, this article examines the extent to which liberal democratic values differ between migrants and non-migrants in Europe and whether potential differences can be explained by socialisation in different political contexts. We measure specific values of liberal democracies using data from the European Social Survey, covering a large number of countries, and from the German Integration Barometer, covering a representative sample of migrants from different countries of origin. This allows us to investigate how structural political socialisation and indoctrination in more or less democratic regimes affect the democratic values of migrants and to what extent possible differences in values diminish when migrants from non-democratic countries settle in democratic countries. The analyses show that all three – non-migrants, migrants from more democratic countries, and migrants from less democratic countries – have high levels of liberal democratic values. At this elevated level, we additionally observe that longer periods of socialisation in less democratic countries of origin reduce, and longer periods in more democratic countries of destination increase, migrants’ support for liberal democratic values. Thus, we find support for socialisation and adaptation processes among immigrants in Europe, but these effects are relatively small.
In this investigation, the effect of Ekman pumping on a quasi-geostrophic (QG) system is explored via the vertical buoyancy flux. The vertical buoyancy flux is the quantity in QG flows that is responsible for the adiabatic transfer between kinetic energy (KE) and available potential energy (APE), as well as the slow-time evolution of the mean buoyancy. Ekman pumping (or suction) is a phenomenon that arises through conservation of mass at no-slip boundaries of rotating fluid systems. Three-dimensional QG numerical simulations are run with and without Ekman pumping at the bottom boundary, as well as with and without a realistic stratification profile. Through theory and numerical experiment, it is shown that Ekman pumping drives a conversion of energy from APE to KE at small scales, and from KE to APE at large scales, even in the absence of a mean isopycnal slope. It is also shown that Ekman pumping affects the mean buoyancy by slightly weakening the stratification near the bottom boundary.
Northern Ireland typifies a highly constrained government. In this case, institutional constraints on the British government lead to a strategy of concession in which transition justice is offered to appease the demands of strong domestic constituencies without a genuine attempt to reckon with past wrongdoings by the British state. By engaging transitional justice for some emblematic cases and not others, the government further propagates the sectarian divisions that legitimate British control. The chapter begins with a discussion of the conflict in Northern Ireland and outlines the wrongdoings committed by the British state. I then evaluate the concessionary strategy that accommodates only certain demands for state accountability. Next is an evaluation of that strategy in practice through a focus on public inquiries and the Historical Enquiries Team. These mechanisms showcase the way certain events and experiences have been thoroughly investigated and adjudicated while other incidents have been obstructed or ignored. To explore the strategy beyond Northern Ireland, I examine transitional justice in the Central African Republic.
Misinformation poses serious risks for democratic governance, conflict, and health. This study evaluates whether sustained, classroom-based education against misinformation can equip schoolchildren to become more discerning consumers of information. Partnering with a state government agency in Bihar, India, we conducted a field experiment in 583 villages with 13,500 students, using a 4-month curriculum designed to build skills, shift norms, and enhance knowledge about health misinformation. Intent-to-treat estimates demonstrate that treated respondents were significantly better at discerning true from false information, altered their health preferences, relied more on science, and reduced their dependence on unreliable news sources. We resurveyed participants 4 months post-intervention and found that effects persisted, as well as extended to political misinformation. Finally, we observe within-household treatment diffusion, with parents of treated students becoming more adept at discerning information. As many countries seek long-term solutions to combat misinformation, these findings highlight the promise of sustained classroom-based education.
At the turn of the twentieth century, few philosophical ideas in Marx’s work gained as much attention as his account of history. Orthodox Marxists made it their programme to closely follow Marx’s development thesis, which posits that the productive forces determine the course of history. The Austromarxist Max Adler (1873–1937), influenced by neo-Kantianism, took more liberties in interpreting – or, perhaps more accurately, ‘reinventing’ – the law of history in practical terms. This article reconstructs Adler’s neo-Kantian ‘reinvention’ of Marx’s account of history. According to Adler, the notion of ‘necessity’ that underpins critical judgements is not grounded in the regularity of history but rather in the moral judgements we make about how history should develop. More specifically, I defend two claims. First, by interpreting human progress as a possibility that presents itself as a necessity from the standpoint of practical rationality, I show that Adler laid the foundation for a critique of the Marxist development thesis that only later gained traction. Second, while Marxists may fear that Kantian formalism cannot address misguided ideological beliefs, I argue that Adler’s neo-Kantian formalism is robustly anti-ideological, emphasising the ideology-emancipating transformation we undergo when we recognise exploitative structures.
Chapter 7 turns to work in crafts and construction, an area of the economy that displayed much sharper distinctions between men’s and women’s work. It explores the role of apprenticeship in creating these gendered patterns before looking at one male-dominated work area, building and construction, and two in which women were often employed, textile and clothing production. Despite the absence of guilds in the great majority of localities providing evidence, the requirement of apprenticeship in many craft occupations effectively excluded women from those areas of work. Yet women’s skilled work in some areas of textile and clothing production, alongside the contributions of non-craftsmen in construction, suggest that specialisation through apprenticeship was just as much about status and prestige, as it was about skill acquisition.
This chapter examines how copyright’s bargain is broken when compared against its incentive and rewards rationales. Copyright grants far exceed what is necessary to incentivise initial production and ongoing investments, and the rewards from creative labour do not filter down to the creators copyright was designed to protect. It then shows how reverting copyright to creators after it has been assigned or licensed, mainly through legal mechanisms, can help address these problems, before examining some of the main arguments against reversion rights (e.g. that it unduly imposes upon the freedom of parties to enter into contractual relationships).
Prosody not only signals the speaker’s cognitive states but can also imitate various concepts. However, previous studies on the latter, the iconic function of prosody, have mostly analyzed novel words and nonlinguistic vocalizations. To fill this gap in the literature, the current study has examined the iconic potential of the prosodic features of existing Japanese imitative words known as ideophones. In Experiment 1, female Japanese speakers pronounced 20 sentences containing ideophones in infant-directed speech. They used a higher f0 to express faster and more pleasant movements. Similar iconic associations were observed in Experiment 2, in which Japanese speakers chose the best-matching pitch–intensity–duration combination for each of the ideophones. In Experiment 3, Japanese speakers chose the best-matching voice quality – creaky voice, falsetto, harsh voice or whisper – for the ideophones. Falsetto was preferred for a light object’s fast motion, harsh voice for violent motion and whisper for quiet motion. Based on these results, we entertain the possibility that the iconic prosody of ideophones provides a missing link in the evolutionary theory of language that began with iconic vocalizations. Ideophones with varying degrees of iconic prosody can be considered to be located between nonlinguistic vocalizations and arbitrary words in this evolutionary path.
This article considers the history of Egypt’s mid-twentieth-century Spiritualist movement through an examination of its periodical, a monthly Arabic magazine called ʿAlam al-Ruh (The World of the Spirit) (1947–1960). As it shows, Egyptian Spiritualists defended and promoted their project by crafting an experimental cosmology, one that blended claims about empirical verification with elements of Islamic and Spiritualist cosmologies. It further shows how this combination of scientism and cosmology reflects a core dynamic within the history of scientific exploration in the Islamic world. Like spiritual seekers and occult practitioners in Muslim societies elsewhere, Egyptian Spiritualists positioned their project as one of eradicating superstition from religion, modernizing the nation, and advancing science. By attending to the Egyptian Spiritualist effort to scientize religion and spiritualize science, this article foregrounds the Islamic tradition’s entanglements with scientific discourses and navigates beyond claims about epistemological rupture that often characterize the study of Islam’s relationship to modern science.
