‘Sistem te laže!’: the anti‐ruling class mobilisation of high school students in Bosnia and Herzegovina

This article presents the case of a high school student‐led protest movement in the Bosnian towns of Jajce and Travnik. Over the course of 2016 and 2017, the students developed opposition to a plan for an ethnically segregated high school in Jajce. In Bosnia and Herzegovina, ethnicity is strongly politicised and limits the political activities of citizens to what is prescribed by the elites of their respective ethnic groups. In particular, Bosnian youth is often named as part of an apathetic ‘lost generation’ whose voices are smothered by this ethno‐political framework. I argue that the political agency of ordinary young Bosnians should not be neglected, since the formulations of their relationship with the state form meaningful political activities. The student protests in Jajce and Travnik are telling examples of their political agency. In an analysis of the protest movement's actions, I show that the students adopt a narrative that opposes the ruling political class and their prevalence of personal interests over the future of younger generations.     

Kings,chieftains and public cult in pre‐Christian Scandinavia

The article addresses the question of the performance of pre‐Christian public cult by political leaders in early medieval Scandinavia. This question is traditionally discussed within the larger theoretical frame of sacral kingship in early medieval Scandinavia. In this article, the key contemporary evidence is presented and discussed with the conclusion that the sources do not show political leaders performing pre‐Christian public cult. Instead, the evidence shows that political leaders participated in private religious rituals whose performance, however, was not connected with political leadership per se.     

Studying the process of enamel powder preparation for émail champlevé by colour measurements and μ‐X‐ray mappings

Colour measurements and non‐destructive μ‐X‐ray mappings have been used for the first time in a comprehensive study of medieval émail champlevé works from different production areas in France and Germany. This approach has given a new insight into the enamel powder preparation process of the glass material used for enamelling. Colour measurements demonstrated that all production centres used glass of very similar hues, but with large differences in colour saturation. The μ‐X‐ray mapping results of blue enamels are described by a semi‐qualitative approach. Significant variations in oxide contents of lead, cobalt, manganese and antimony oxides were found. The variations suggest that more than one glass material was used to prepare the powder for enamelling. The variations in antimony and cobalt show that glass had different degrees of opacity and colour depth. The manganese and lead contents, which do not correlate with the cobalt or antimony contents, indicate that probably glass of different base compositions was used to prepare the enamel powder for one champlevé field.     

Gendered Agendas: The Secrets Scholars Keep about Yorùbá‐Atlantic Religion

Whereas scholars have often described the material interests served by any given social group's selective narration of history, this article catches scholars in the act of selectively narrating Yorùbá‐Atlantic cultural history in the service of their own faraway activist projects. Anthropologist Ruth Landes' re‐casting of the Afro‐Brazilian Candomblá religion as an instance of primitive matriarchy not only encouraged feminists abroad but also led Brazilian nationalist power‐brokers to marginalise the male, and often reputedly homosexual, priests who give the lie to Landes's interpretation. In the service of a longdistance Yorùbá nationalist agenda, sociologist Oyeronke Oyewumi has declared traditional Yorùbá society ‘genderless’, and found, among both North American feminist scholars and Yorùbá male scholars, allies in concealing the copious evidence of gender and gender inequality in Yorùbá cultural history. What these historical constructions lack in truth value they make up for in their power to mobilise new communities and alliances around the defence of a shared secret. The article addresses how politically tendentious scholarship on gender has inspired new social hierarchies and boundaries through the truths that some high‐profile scholars have chosen to silence.     

Royal burial and the cult of kingship in France and England, 1060–1330

In the late-eleventh and early twelfth centuries, French and English royal burials were relatively unceremonial, low-key affairs, a contrast with the obsequies of other contemporary rulers such as the Holy Roman emperors. One reason for that may be the dominance of reforming ecclesiastics in arranging the funeral rites in England and France; another, the importance attached by the monarchs to obtaining personalised intercession from ascetic monks. By the early fourteenth century, however, the French and English sovereigns were commemorated after death in magnificent ceremonies and monuments. In the intervening centuries, those kings and their followers had shown a growing interest in the creation and promotion of royal saint-cults; in the honouring of royal remains; in public and splendid funeral ceremonies and lawish tombs; and in the creation and development of imposing burial-churches at Saint-Denis and Westminster. During this time there was an increasing emphasis upon the image and panoply of monarchy in both kingdoms which was rooted to a large extent in the personal and political rivalry of their rulers. The new splendours of royal burials can be seen as one important part of those developments.     

The p‐Regions Problem. p‐区域问题

The p‐regions problem involves the aggregation or clustering of n small areas into p spatially contiguous regions while optimizing some criteria. The main objective of this article is to explore possible avenues for formulating this problem as a mixed integer‐programming (MIP) problem. The critical issue in formulating this problem is to ensure that each region is a spatially contiguous cluster of small areas. We introduce three MIP models for solving the p regions problem. Each model minimizes the sum of dissimilarities between all pairs of areas within each region while guaranteeing contiguity. Three strategies designed to ensure contiguity are presented: (1) an adaptation of the Miller, Tucker, and Zemlin tour‐breaking constraints developed for the traveling salesman problem; (2) the use of ordered‐area assignment variables based upon an extension of an approach by Cova and Church for the geographical site design problem; and (3) the use of flow constraints based upon an extension of work by Shirabe. We test the efficacy of each formulation as well as specify a strategy to reduce overall problem size.     

Prison and sacrament in the cult of saints: images of St Barbara in late medieval art

This article analyses the changing visual representation of St Barbara during the later middle ages. The article identifies a shift in St Barbara's iconography: whereas earlier medieval representations of the saint almost always show her with her prison tower, a number of fifteenth-century representations show the saint holding a chalice and host. The article traces how and why this shift occurred. In particular, the article explores the ways in which medieval thinking linking incarceration and liberation were integrated into new representations of St Barbara to stress her intercessionary, sacramental functions. Overall, the article argues that the visual transformation of St Barbara's prison tower into a liturgical vessel reveals how saints like Barbara were increasingly viewed as conduits to the inclusive sort of freedom that participation in Christianity's sacramental economy invited.     

Variabilité et fréquence des cycles de gel‐dégel dans la région de Québec, 1977–2006

Freeze‐thaw cycles are most common at the beginning or near the end of the winter season. These cycles have various effects on the ecosystems of Eastern Canada, affecting both biotic and abiotic components of temperate cold environments. Using air temperature minima and maxima from four meteorological stations close to Québec City, we determined the frequency of daily freeze‐thaw cycles for the last 30 years. The results show no significant increase in the number of freeze‐thaw cycles despite a small increase in air temperature. Polynomial curves describing the relationship between mean air temperatures and the number of freeze‐thaw cycles were calculated. Based on these equations and anticipating a climate change scenario, we projected future freeze‐thaw cycles. Assuming a 5 °C increase in mean air temperatures by 2100, we estimated that the number of days with a freeze‐thaw cycle could increase by approximately 20 days per winter. The increase in the number of such cycles will be concentrated during the coldest months of the winter (January and February).     

The ‘woman‐in‐conflict’ at the UN Security Council: a subject of practice

Since the adoption of UN Security Council Resolution 1325, the woman‐in‐conflict has emerged as a central figure in the discourse of the UNSC Women, Peace and Security policy community. She is an ever‐present referent in discussions, the person in whose name critique is launched or action demanded. This figure is a representation of the needs and interests of the uncountable, faceless and nameless women affected by and living through war; a representation that takes place through imbuing her with particular meaning or characteristics. These meanings shape how the figure is understood in Women, Peace and Security discourse, which, in turn, constructs the horizons of possibility for both current and future policy and its implementation. This article explores how this figure is produced as a subject through layers of representation and is deeply embedded in the practices and relationships of power in the policy community. It suggests that accounting for these will offer an opportunity for feminist advocates to engage in this institutional space in more considered and effective ways.     

Determinants of Variation in Population–Employment Interaction Findings: A Quasi‐Experimental Meta‐Analysis. 人口‐就业相互作用的决定因素研究：一种准实验元分析法

This article reports about a metaregression analysis of empirical results generated using data for the northern Netherlands (1988–2002) in order to investigate the ambiguity in results in the population–employment interaction literature. Specifically, the analysis deals with the issue whether “jobs follow people” or “people follow jobs.” The article starts with introducing the basics of quasi‐experimental meta‐analysis and with identifying some advantages of using quasi‐experimental meta‐analysis as compared with the standard meta‐analysis approach. Two subsequent sections document the selection of the population–employment interaction model and salient characteristics of the data set as well as the setup of the primary analyses. A total of 4,050 quasi‐experimental empirical results for the jobs–people direction of causality are generated using different specifications and estimators for a spatial econometric interaction model. The subsequent metaregression analysis reveals that the empirical results are largely shaped by the spatial, temporal, and employment characteristics of the data sampling. The results also appear much more sensitive to different measurements of the model's key variables when compared with alternative specifications of the spatial weights matrix. The main determinant driving empirical results about jobs–people causality are differences in model specification and estimation, as revealed by an inherent bias in parameter estimates and misguided inferences for some of the commonly used specifications. Finally, suggestions for future research are identified.
