The huge parastatal sectors in postcolonial African societies interested sociologists in the 1970s and 1980s, but have never found a historical discussion – and the experience of change towards the democratization (eventually) has not yet been interpreted by historians. This study attempts to bring both elements together for the case of Benin, a country particularly shaken by massive economic decline, lay-offs and unemployment in the second half of the 1980s. It relies on an unusual and spectacular source, a series of petitions sent by workers and workers’ delegates to the presidential office of Mathieu Kérékou in 1989/90 (the presidential office partly added to these petitions whole dossiers of comments and correspondence with other authorities, i.e. ministerial directorates and the police). This analysis highlights how parastatal workers and their spokesmen tried to communicate about economic and social disaster with the authorities, how they protested and attempted to make claims about social norms and justice, and how they attacked “corruption”. I would hold that the cases studied cannot stand for a model of experiences, but they nevertheless represent a number of elements of a social history of decline: as well as protests and arguments, and views on the practice of petitioning, the discussion will also highlight individual trajectories that nevertheless exemplify, in my view, representative experiences and a history of daily life in Benin's parastatal sector. The interpretation also attempts to show how imminent democratization, through the creation of a National Conference in early 1990, changed the strategies and the context of workers’ protest. It includes a number of exemplary, and quite spectacular, cases of mismanagement and closing of parastatal companies, such as the Société Sucrière de Savè and SONICOG. I would think that the approach is unique so far for both Beninese and West African history.

The effect of freshwater sources on wintertime sea-ice CO2 processes was studied from the glacier front to the outer Tempelfjorden, Svalbard, in sea ice, glacier ice, brine and snow. March–April 2012 was mild, and the fjord was mainly covered with drift ice, in contrast to the observed thicker fast ice in the colder April 2013. This resulted in different physical and chemical properties of the sea ice and under-ice water. Data from stable oxygen isotopic ratios and salinity showed that the sea ice at the glacier front in April 2012 contained on average 54% of frozen-in glacial meltwater. This was five times higher than in April 2013, where the ice was frozen seawater. In April 2012, the largest excess of sea-ice total alkalinity (AT), carbonate ion ([CO32−]) and bicarbonate ion concentrations ([HCO3−]) relative to salinity was mainly related to dissolved dolomite and calcite incorporated during freezing of mineral-enriched glacial water. In April 2013, the excess of these variables was mainly due to ikaite dissolution as a result of sea-ice processes. Dolomite dissolution increased sea-ice AT twice as much as ikaite and calcite dissolution, implying different buffering capacity and potential for ocean CO2 uptake in a changing climate.

The omnipresence of radical uncertainty asks for a concept of causality that moves beyond the notion of predicted probabilities. Protean power is a most important contribution to move International Relations research in this direction. Yet, some of the key components need further grounding in existing concepts and debates. First, protean power should include the notion of directionality in order to be power. Second, it should allow for an analysis of the different forms of relation between protean power and different types of uncertainties. And it should focus on features of the power relationship instead of the context in which it takes place to be able to transfer it to contexts other than uncertainty.

The United Nations 2030 Agenda for Sustainable Development sets a framework of universal Sustainable Development Goals (SDGs) to address challenges to society and the planet. Island invasive species eradications have well-documented benefits that clearly align with biodiversity conservation-related SDGs, yet the value of this conservation action for socioeconomic benefits is less clear. We examine the potential for island invasive vertebrate eradications to have ecological and socioeconomic benefits. Specifically, we examine: (1) how SDGs may have been achieved through past eradications; and (2) how planned future eradications align with SDGs and associated targets. We found invasive vertebrate eradication to align with 13 SDGs and 42 associated targets encompassing marine and terrestrial biodiversity conservation, promotion of local and global partnerships, economic development, climate change mitigation, human health and sanitation and sustainable production and consumption. Past eradications on 794 islands aligned with a median of 17 targets (range 13–38) by island. Potential future eradications on 292 highly biodiverse islands could align with a median of 25 SDG targets (range 15–39) by island. This analysis enables the global community to explicitly describe the contributions that invasive vertebrate management on islands can make towards implementing the global sustainable development agenda.

This Research Reflection provides an overview of three interrelated topics: (i) lameness in dairy cows, demonstrating the underpinning importance of the condition, (ii) dairy farmer detection, diagnosis and treatment of lameness and associated foot lesions as well as dairy farmer perceptions towards the condition and (iii) lameness detection technologies, and their potential application on farm to automate the detection of lameness in commercial dairy herds. The presented literature clearly demonstrates that lameness is a major health issue in dairy herds, compromising dairy cow welfare and productivity, and resulting in significant economic implications for dairy farmers. Despite this, dairy farmers fail to perceive lameness as a serious threat to their dairy business. This restricted perception of the importance of lameness may be a product of limited ability to detect lame cows. Many automated lameness detection technologies have been proposed to assist dairy farmers in managing their herds. However, limitations such as cost, performance and dairy farmer perception of the usefulness of these technologies, has lead to poor uptake. It can, therefore, be concluded that there is a need to more thoroughly evaluate the effectiveness of these technologies under on-farm conditions, potentially in the form of a demonstration farm network. This will allow generation of the necessary data required to show dairy farmers that these technologies are reliable and are economically rational for their dairy business.

The aim of this study was to examine the positive relationship between religiosity and fertility from the perspective of perceived consequences of parenthood. Previous studies in Germany have found that highly religious people ascribe higher benefits and lower costs to having children. Furthermore, the impact of costs and benefits on fertility is less pronounced among the highly religious. This study tested these mechanisms for fertility intentions and in the context of Poland – a country with a low fertility rate and high religiosity in comparison to other European countries. A sample of 4892 men and women of childbearing age from the second wave of the Polish version of the Generations and Gender Survey conducted in 2014/2015 was used. First, the extent to which perceived costs and benefits mediate the impact of religiosity on fertility intentions was analysed. Second, whether religiosity moderates the impact of perceived costs and benefits on fertility intentions was investigated. The results show that part of the positive effect of religiosity on fertility intentions can be explained by more-religious people seeing higher benefits of having children. Furthermore, but only in the case of women, religiosity moderates the impact of perceived costs on fertility intentions, suggesting that the effect of perceived costs decreases with increasing religiosity.

We define and study generalizations of simplicial volume over arbitrary seminormed rings with a focus on p-adic simplicial volumes. We investigate the dependence on the prime and establish homology bounds in terms of p-adic simplicial volumes. As the main examples, we compute the weightless and p-adic simplicial volumes of surfaces. This is based on an alternative way to calculate classical simplicial volume of surfaces without hyperbolic straightening and shows that surfaces satisfy mod p and p-adic approximation of simplicial volume.

To create a reliable radiocarbon calibration curve, one needs not only high-quality data but also a robust statistical methodology. The unique aspects of much of the calibration data provide considerable modeling challenges and require a made-to-measure approach to curve construction that accurately represents and adapts to these individualities, bringing the data together into a single curve. For IntCal20, the statistical methodology has undergone a complete redesign, from the random walk used in IntCal04, IntCal09 and IntCal13, to an approach based upon Bayesian splines with errors-in-variables. The new spline approach is still fitted using Markov Chain Monte Carlo (MCMC) but offers considerable advantages over the previous random walk, including faster and more reliable curve construction together with greatly increased flexibility and detail in modeling choices. This paper describes the new methodology together with the tailored modifications required to integrate the various datasets. For an end-user, the key changes include the recognition and estimation of potential over-dispersion in 14C determinations, and its consequences on calibration which we address through the provision of predictive intervals on the curve; improvements to the modeling of rapid 14C excursions and reservoir ages/dead carbon fractions; and modifications made to, hopefully, ensure better mixing of the MCMC which consequently increase confidence in the estimated curve.

Population ageing and discourses on healthy ageing have led to a growing interest in social dancing for seniors. While senior dance has been described as both common and contributing to good health, the fundamental connection between bodily and temporal dimensions has been fairly neglected. As a result, there is a risk of portraying dance among older adults as a general practice, while at the same time the senior dance's potential to shed light on relations between temporality and ageing is not utilised. Based on qualitative interviews with 25 women and eight men, aged 52–81, in Sweden, whose main leisure activity was dancing, this article sheds light on this knowledge gap by illustrating the pleasurable experiences of senior dance. The results illustrate that the pleasurable experiences of dancing can be understood as three different experiences of temporality: embodied experience of extended present, an interaction with synchronised transcending subjectivities and age identities with unbroken temporality. The results also highlight the central role that temporal aspects play in processes around subjectivities in later life, as well as the close connection between ageing embodiment and temporality. They also illustrate the ability of dance to create wellbeing, not only through its physical elements, but also through the sociality that constitutes the core of dancing. In light of these results, the article argues that the temporal processes relate to individuals’ diverse relationship with the world and that they therefore play a central role in subjective experiences of ageing.
