Scholars of various backgrounds have noted how societies across the globe have come to rely on more and more policing and incarceration since the late 1970s. To date, however, detailed analyses of the causes and consequences of this “punitive turn” have been limited to the Global North, with the vast majority of studies focused on the expansion of states’ capacity for violence. This article offers a corrective to the global study of the punitive turn by tracing the rise of South Africa’s private security industry from its inception in the late apartheid period to its current position as one of the largest of its kind in the world. Using newspaper reports, archival material from the apartheid state’s security apparatus, and ethnographic interviews of former and current members of the security industry, it shows how counterinsurgency doctrine, civil war, and deindustrialization shaped South Africa’s punitive turn, precipitating a process where violence was devolved from the state to private actors, including local militias, vigilante groups, and private security firms. This process, it is argued, is far from anomalous, and should be seen as a paradigm for the way the post-1970s punitive turn has unfolded in the majority of the world.

Before World War I, the Ottoman Empire ruled the southwestern region of the Arabian Peninsula. However, unlike other Ottoman territories in Eastern Europe and the Middle East, the fate of this region was not decided during the Paris Peace Conference. This created a vacuum of power that allowed the local elites of Arabia to engage in a lengthy process of conflict, negotiations, peace talks, and the exchange of ideas to resolve issues of legitimacy, sovereignty, borders, and cultural differences. This article argues that these local elites of Arabia developed an alternative model of statehood and sovereignty that persisted until the outbreak of the Gulf War in 1990. The immediate result of this new model was the separation of al-Mikhlāf al-Sulaimānī region and the transformation of the people of the Najrān region into a sectarian group.

Newly elevated to species rank, the Bahama Nuthatch Sitta insularis is or was a bark- and twig-gleaning insectivore only known in life from the pine forests of Grand Bahama in the Bahamas archipelago. It became increasingly difficult to find in the past 50 years, seemingly in part in response to multiple hurricanes in this century. In spring (June–April) 2018, when it was still known to be extant, we divided the island into seven sections and carried out point count transects with playback and measured habitat variables at 464 locations in pine forest across Grand Bahama. We made only six observations at six locations, all in the region of Lucayan North and each involving a single nuthatch (possibly all the same individual). Fourteen count points were within 500 m of the six locations, and tree size at these sites was greater in height and girth than at sites with no observations and indeed than at other sites within Lucayan North. Count points within 500 m of nuthatch records in 2004–2018 had larger trees and more snags than survey points over 500 m away from previous detections, while count points within 500 m of our 2018 nuthatch records tallied more snags than did those within 500 m of the 2004–2007 records. Declines in habitat quality, habitat extent, nesting substrate, and food availability (driven by logging, attritional island development, and the direct and indirect effects of hurricanes), plus speculated increases in populations of invasive predators/competitors and in major mortality events (hurricanes, increasing in force and frequency with climate change), are suspected to be the ultimate causes of the decline of the nuthatch, with Hurricanes Matthew and Dorian the proximate causes of its evident extinction in 2019.

Founded by Booker T. Washington in 1900, the National Negro Business League (NNBL) sought to unite Black business owners, promote entrepreneurship, and develop economic power. Despite its prominence in the early twentieth century, the group declined after Washington’s death in 1915. As a result, little is known about its organizational development. This study uses data on state and local Negro Business Leagues (NBLs), along with active and life members of the NNBL, to better understand the group’s first fifteen years. Analyses reveal that the NNBL’s development reflected closely the social and economic context of early twentieth century Black America. Generally speaking, the NNBL was stronger in states with larger urban Black populations and where the value of Black-owned farms was higher, consistent with the importance of agriculture to Black business during this era. These results both shed light on the NNBL’s early success and suggest avenues for future research on its decline.

Loss of skeletal muscle strength and mass (sarcopenia) is common in older adults and associated with an increased risk of disability, frailty and premature death. Finding cost-effective prevention and treatment strategies for sarcopenia for the growing ageing population is therefore of great public health interest. Although nutrition is considered an important factor in the aetiology of sarcopenia, its potential for sarcopenia prevention and/or treatment is still being evaluated. Nutrition research for sarcopenia utilises three main approaches to understand muscle-nutrition relationships, evaluating: single nutrients, whole foods and whole diet effects – both alone or combined with exercise. Applying these approaches, we summarise recent evidence from qualitative and quantitative syntheses of findings from observational and intervention studies of healthy older adults, and those with sarcopenia. We consider protein supplements, whole foods (fruits and vegetables) and the Mediterranean diet as exemplars. There is some evidence of beneficial effects of protein supplementation ≥ 0·8 g/kg body weight/d on muscle mass when combined with exercise training in intervention studies of healthy and sarcopenic older adults. In contrast, evidence for effects on muscle function (strength and physical performance) is inconclusive. There is reasonably consistent epidemiological evidence suggesting benefits of higher fruits and vegetables consumption for better physical performance. Similarly, higher adherence to the Mediterranean diet is associated with beneficial effects on muscle function in observational studies. However, intervention studies are lacking. This review discusses how current evidence may inform the development of preventive and intervention strategies for optimal muscle ageing and nutritional public policy aimed at combatting sarcopenia.

Despite the urgent need for plant-based dietary shifts, few studies have examined current diet trajectories using longitudinal data. This study analyzed dietary transitions of French adults over 8 years (2014-2022), assessing diet quality and the role of various socio-economic factors. Consumption data from 17 187 NutriNet-Santé cohort participants, weighted for the French Census, were collected via FFQ in 2014, 2018 and 2022. Adopting a gender-specific approach, consumption changes in twenty-three food groups were assessed over time. Diet quality was evaluated using the Comprehensive Diet Quality Index score, categorising foods into ‘healthy’ and ‘unhealthy’. Socio-economic analysis targeted four food groups (red meat (including fresh beef, pork, offal and lamb), processed meat (e.g. sausages, ham and bacon), legumes and whole-grain products), strongly linked to mortality risk and recognised as significant markers of the sustainable diet transition. All analyses were conducted using multi-adjusted mixed-effects models. Consumption of some healthy plant-based foods (nuts +59 %, legumes +22 %, whole-grain products +7 %) significantly increased over time, while consumption of some unhealthy foods (red meat −19 %, refined cereals −18 %, sweetened drinks −15 %) decreased. Conversely, consumption of prepared and mixed dishes (+16 %) and processed meat (+35 %) increased. These changes differed in magnitude between genders and translated into an improved diet quality score (Comprehensive Diet Quality Index). Occupational status was linked to longitudinal changes in food consumption, showing increased consumption of plant-based foods among students and higher socio-professional categories. Our findings provide accurate data on trends and factors for targeted initiatives, guiding strategic interventions for a sustainable dietary transition.

This article examines the online reaction to the linguistic performance of a pro-China Hong Kong singer-actor in a commercial where he speaks Hong Kong English. Paradoxically, the posters criticizing his English are Hongkongers themselves, while those showing admiration are mainland Chinese. Understanding this paradox requires an appreciation of the multiple and complex orders of indexicality through which the variety is evaluated and of the increasing use of linguistic evaluations as a proxy for political judgements in a society undergoing significant changes. An analysis of online comments and remixes associated with the commercial shows that Hong Kong social media users attribute a range of different indexical meanings to the celebrity's English to shame him for his perceived ‘betrayal’ and to reclaim a sense of social superiority over mainlanders in the face of unease about Hongkongers’ cultural distinctiveness. It unpacks complexities surrounding the deployment of language ideologies in societies experiencing sociopolitical upheavals.

Sperm infertility or subfertility is detrimental to the precious highland germplasm like yak whose population has been gradually declining in India. Understanding the ‘omic’ landscape of infertile or subfertile yak sperm can reveal some interesting insights. In an attempt to do the same, this study considered the semen of infertile or subfertile yak bulls for whole-genome and transcriptome evaluations. DNA sequencing revealed that the yak sperm genome contains the necessary genes to carry out all the important biological processes related to the growth, development, survival and multiplication of an organism. Interestingly, RNA Seq results highlighted that genes like VAMP7, MYLK, ARAP2 and MARCH6 showed increased expression, while biological processes related to immune response (GO:0043308, GO:0002447, GO:0002278, GO:0043307, GO:0043312, GO:0002283, GO:0043299 and GO:0002446) were significantly overrepresented. These findings hint at a possible role played by immune system in regulating infertility or subfertility in yaks. Further, in-depth studies can validate these findings and help in improving our biological understanding in this area.

The zeolitic rocks of Akrotiri, on Santorini Island (Aegean Sea, Greece), can be grouped according to the zeolite minerals present. The first group includes zeolitic rocks that contain only clinoptilolite, the second group contains clinoptilolite and mordenite and the third group contains only mordenite. Clinoptilolite accounts for up to 56 wt.% and mordenite for up to 69 wt.% of the rocks. All samples contain feldspars (8–36 wt.%), clay minerals (6–8 wt.%), quartz (3–6 wt.%), opal-CT (2 wt.%), amphibole (2–4 wt.%) and amorphous materials (4–7 wt.%). The studied samples were classified chemically as andesites or dacites. The ammonium-exchange capacity of the studied samples was 104–158 meq 100 g–1. According to Commission Implementing Regulation (EU) No. 651/2013, zeolitic rocks that contain ≥80 wt.% clinoptilolite, ≤20 wt.% clay minerals and are free of fibrous minerals and quartz can be used as feed additives in animal husbandry. Zeolites with fibrous habit (mordenite, erionite, secondarily roggianite and mazzite) and SiO2 minerals such as quartz, cristobalite and tridymite can be dangerous to both humans and animals. The mineralogical study showed that, due to their low clinoptilolite content and the presence of both quartz and fibrous mordenite, the studied zeolitic rocks do not conform with European Regulation No. 651/2013. As a result, their use as feed additives and nutrition supplements is prohibited.

This article is about the seminar held at Luiss University in Rome on 17 June 2024. The seminar focused on ‘The End of Christian Democracy: A New Direction for Research’ and was the first milestone and official launch of the PRIN research project ‘The End of Christian Democracy: The Collapse of a Political Dream – Voices from the Margins’, led by a consortium of four universities: Luiss, Roma Tre, Bologna and Suor Orsola Benincasa, Naples.

This paper empirically examines the dynamic relationship between stock market volatility and commodity prices through the time-varying risk aversion channel using daily data between December 31 in 1999 and June 14 in 2021. We employ a time-varying structural-form vector autoregressive model (VAR) model with (aggregate, sectoral and sixteen individual) commodity prices. The results suggest that the transmission mechanism of stock market volatility shocks on the commodity prices change over time. The negative effect of stock market volatility on commodity prices is more statistically significant in the 2008–09 Global Financial Crisis than that during the COVID-19 pandemic in 2020. Further, the effect is greater in energy commodities compared to the agricultural and metals markets. The long-lasting negative effect of risk aversion is stronger compared to that of the expected stock market volatility on the commodity price. The change in the stock-commodity transmission mechanism is likely due to changes in underlying sources of risk aversion and expected uncertainty over time.

This short contribution presents an enigmatic clay mould recovered from a tile kiln in Vindolanda's North Field. This complete mould contains an impression of Apollo in bust form, but its exact use is unclear. This paper presents the mould and discusses its potential use for the manufacture of ceramic figurines. Found in an industrial area of the site, its discovery also provides valuable evidence for craft production along this frontier and hints at a largely unknown provincial industry.

In this paper, we deal with a weighted eigenvalue problem for the anisotropic $(p,q)$-Laplacian with Dirichlet boundary conditions. We study the main properties of the first eigenvalue and a reverse Hölder type inequality for the corresponding eigenfunctions.
