Published: May 2021

Abstract
Variation in human activities has greatly impacted the processes and intensities of erosion, sediment transport and storage throughout the Late Holocene, and many lowland rivers around the world have responded to these variations. Although this long-term process–response relationship has been established before, the effects of short-term (c.200-year) changes in human impact on lowland rivers are less well studied. Here, we followed an integrated approach whereby observations of floodplain changes are evaluated against detailed data on human impact for three lowland rivers in the Belgian loess belt: Dijle, Mombeek and Gete rivers. Pollen data were used to reconstruct changes in local and regional vegetation and to calculate human impact scores. Corings along transects and a database of c.160 radiocarbon ages were used to reconstruct geomorphic changes in the river valleys. Our results show a decrease in human impact between 200 and 800 AD, which can be related to the decreased population density in Europe during the first millennium AD. During this period, forests in the studied catchments regenerated, soil erosion decreased, hillslope–floodplain connectivity decreased due to the regeneration of valley-side vegetation barriers, and sediment input in the floodplain decreased. A reaction to this decreased human impact can be observed in the river valleys during the first millennium AD, with a regrowth of the alder carr forest and an increase in the organic matter content of the alluvial deposits with a local reactivation of peat growth. The observed trajectories of Belgian river valleys during the first millennium AD provide more insight into the sensitivity of these river valleys to short-term variations in human impact. These results can in turn be used to better estimate the effects of future changes in the catchments on the fluvial system.
Ethnic Boundaries and Territorial Borders: On the Place of Lezgin Irredentism in the Construction of National Identity in Azerbaijan
Authors: Sayfutdinova Leyla 
Published: May 2021

AbstractThe Lezgin irredentist movement is one of the less-studied national movements in the post-Soviet space, despite affecting the strategically important Russian-Azerbaijani borderlands and the bordering process between the two post-Soviet states. This article aims to fill this gap and to examine the impact of the Lezgin national movement on the development of territorial nationalism in early post-Soviet Azerbaijan. Based on the analysis of media publications in three Azerbaijani newspapers between 1992 and 1996, I argue that the movement contributed to consolidating the territorial vision of the Azerbaijani nation as incorporating groups historically settled in this territory. While media coverage stressed friendship between ethnic Azerbaijanis and Lezgins, the responsibility for secessionist claims was placed on external forces, particularly Russia and Armenia. In the long term, this framing led to the securitization of ethnic minority activism as a major threat to Azerbaijani statehood.
The Ottoman Empire, the United States, and the legal battle over extradition: the “Kelly affair”
Authors: Kamay Berna 
Published: May 2021

AbstractThis article examines extradition in nineteenth-century Ottoman diplomacy by exploring an illustrative legal conflict between the Ottoman Empire and the United States. The Kelly affair, which revolved around the murder of an Ottoman subject by an American sailor in Smyrna (Izmir) in 1877, sparked a diplomatic dispute that lasted for several decades. The controversy stemmed from conflicting interpretations of the treaty of commerce signed in 1830. The inability to reach a consensus pushed the parties to resort to the 1874 Extradition Treaty, which was the only official Ottoman extradition agreement. The Kelly affair poignantly illustrates how extradition, an issue of international law that touched on territorial jurisdiction and subjecthood, was a complicated and ill-defined matter when addressed in practice. By investigating the confrontation between the Ottoman Empire and the USA, both putative secondary powers on the international stage at the time, this article challenges the existing historical narratives on interimperial relations that highlight Europe as the locus of power and agency. Even though ad hoc political actions overshadowed the binding force of the treaty text, it demonstrates how both governments adopted a political strategy that moved beyond the intrinsic arguments and logic of the capitulations to embrace a novel legal discourse.
MIDDLE BRONZE AGE JERUSALEM: RECALCULATING ITS CHARACTER AND CHRONOLOGY

Published: May 2021

ABSTRACTThe following paper presents the results of radiocarbon (14C) dating of Middle Bronze Age (MB) contexts in Jerusalem. The dates, sampled with microarchaeology methods from three different locations along the eastern slopes of the city’s ancient core, reveal that Jerusalem was initially settled in the early phases of the period, with public architecture first appearing in the beginning of the 19th century BC and continued to develop until the 17th century BC. At that time, a curious gap in settlement is noted until the 16th century BC, when the site is resettled. The construction of this phase continued into the early 15th century BC. The dates presented are discussed in both the site-level, as well as their far-reaching implications regarding MB regional chronology. It is suggested here that the high chronology, dating the Middle Bronze Age between 2000 and 1600 BC is difficult to reconcile with dates from many sites. In contrast, a more localized chronology should be adopted, with the Middle Bronze Age continuing into the early 15th century BC in certain parts of the southern Levant, such as the region of Jerusalem.
BUILDING HIGH-PRECISION AMS14C BAYESIAN MODELS FOR THE FORMATION OF PERI-ABANDONMENT DEPOSITS AT BAKING POT, BELIZE

Published: May 2021

ABSTRACTDeposits linked to abandonment have been widely recorded across the Maya lowlands, associated with the final activities occurring in ceremonial areas of Classic Maya centers. Various models have been applied to explain the activities that lie behind the formation of these contexts, including those linked to rapid abandonment (e.g., warfare) and others focused on more protracted events (termination rituals, and/or pilgrimages). Here, we assess Bayesian models for three chronological scenarios of varying tempo to explain the formation of peri-abandonment deposits at Baking Pot, Belize. Using stratigraphic information from these deposits, hieroglyphic dates recovered on artifacts, and direct dates on human skeletal remains and faunal remains from distinct layers in three deposits in Group B at Baking Pot, we identify multiple depositional events that spanned the eighth to ninth centuries AD. These results suggest that the processes associated with the breakdown of institutionalized rulership and its command of labor to construct and maintain ceremonial spaces were protracted at Baking Pot, with evidence for the final depositional activity dated to the mid-to-late ninth century. This interval of deposition was temporally distinct from the earlier deposition(s) in the eighth century. Together, these data offer a detailed view of the end of the Classic period at Baking Pot, in which the ceremonial spaces of the site slowly fell into disuse over a period of more than a century.
Effects of crustacean hyperglycaemic hormone RNA interference on regulation of glucose metabolism in Litopenaeus vannamei after ammonia-nitrogen exposure

AbstractTo unveil the adaptation of Litopenaeus vannamei to elevated ambient ammonia-N, crustacean hyperglycaemic hormone (CHH) was knocked down to investigate its function in glucose metabolism pathway under ammonia-N exposure. When CHH was silenced, haemolymph glucose increased significantly during 3–6 h, decreased significantly during 12–48 h and recovered to the control groups’ level at 72 h. After CHH knock-down, dopamine (DA) contents reduced significantly during 3–24 h, which recovered after 48 h. Besides, the expressions of guanylyl cyclase (GC) and DA1R in the hepatopancreas decreased significantly, while DA4R increased significantly. Correspondingly, the contents of cyclic AMP (cAMP), cyclic GMP (cGMP) and diacylglycerol (DAG) and the expressions of protein kinase A (PKA), protein kinase G (PKG), AMP active protein kinase α (AMPKα) and AMPKγ were significantly down-regulated, while the levels of protein kinase C (PKC) and AMPKβ were significantly up-regulated. The expressions of cyclic AMP response element-binding protein (CREB) and GLUT2 decreased significantly, while GLUT1 increased significantly. Moreover, glycogen content, glycogen synthase and glycogen phosphorylase activities in hepatopancreas and muscle were significantly increased. Furthermore, the levels of key enzymes hexokinase, pyruvate kinase and phosphofructokinase in glycolysis (GLY), rate-limiting enzymes citrate synthase in tricarboxylic acid and critical enzymes phosphoenolpyruvate carboxykinase, fructose diphosphate and glucose-6-phosphatase in gluconeogenesis (GNG) were significantly decreased in hepatopancreas. These results suggest that CHH affects DA and then they affect their receptors to transmit glucose metabolism signals into the hepatopancreas of L. vannamei under ammonia-N stress. CHH acts on the cGMP-PKG-AMPKα-CREB pathway through GC, and CHH affects DA to influence cAMP-PKA-AMPKγ-CREB and DAG-PKC-AMPKβ-CREB pathways, thereby regulating GLUT, inhibiting glycogen metabolism and promoting GLY and GNG. This study contributes to further understand glucose metabolism mechanism of crustacean in response to environmental stress.
Political Equality and Substantive Representation by Interest Groups
Authors: Boräng Frida , Naurin Daniel 
Published: May 2021

AbstractThe interest group literature has long struggled with how to empirically approach the normative idea of a non-biased group system. While most previous attempts have focused on the descriptive representation of different types of groups, this article argues that substantive representation of citizens' attitudes is closer to the democratic principle of equal effective participation. It develops a methodological approach that captures substantive representation with respect to agenda priorities and policies by surveying interest groups on how much time they spend on lobbying in different policy areas, and in which direction they lobby on salient policy issues. The responses are compared with opinion data to estimate the level of political (in)equality. The findings from the case of Sweden – where relatively high levels of equality would be expected, but striking levels of inequality based on socio-economic status are instead found – highlight the perseverance of what Schattschneider once called the upper-class bias of the pressure system.
The Political Implications of Personality in Canada
Authors: Bergeron Thomas , Galipeau Thomas 
Published: May 2021

AbstractFew studies have focused on the Canadian context to examine the political impacts of personality. Even though the Canadian Election Study (CES) has measured the Big Five personality traits since 2011, very few studies have taken advantage of this data to assess personality's political role among the Canadian electorate. Using CES data from the three latest elections (2011, 2015 and 2019), we first explore how reliable the measurement of personality is. Except for agreeableness in 2015, the correlations across the personality items are similar to what is typically found in the literature. We next examine how personality affects ideology and partisan identity in the Canadian context. We show that a two-dimensional measurement of ideology refines our understanding of the impacts of personality on ideology. The findings also suggest that personality plays an essential role in forming ideology in Canada but has a limited impact on partisanship.
A Copper Still and the Making of Rum in the Eighteenth-Century Atlantic World
Authors: Zahedieh Nuala 
Published: May 2021

AbstractThis article focuses on a copper still transported from London to the Mesopotamia estate in Jamaica and used to convert waste sugar products into rum, one of the many New World intoxicants which transformed British consumption patterns in the early modern period. Much has been written about the consumer revolution which allowed these commodities to be absorbed into everyday lives but less interest has been shown in the producer revolution needed to get the goods to market. The labour, skills, and materials embodied in the production and use of the copper still highlight how slave production of rum was integrated into a steadily advancing industrial capitalism linking dispersed sites and workers on both sides of the Atlantic. Rum production was a collaborative effort in which Caribbean plantations were inextricably chained to the local, regional, and international economies, and it involved adaptations in skills, tools, and techniques which were incorporated into Britain's long, slow industrial revolution.
State Formation in Korea and Japan, 400–800 CE: Emulation and Learning, Not Bellicist Competition
Authors: Huang Chin-Hao , Kang David C. 
Published: May 2021

AbstractState formation occurred in Korea and Japan 1,000 years before it did in Europe, and it occurred for reasons of emulation and learning, not bellicist competition. State formation in historical East Asia occurred under a hegemonic system in which war was relatively rare, not under a balance-of-power system with regular existential threats. Korea and Japan emerged as states between the fifth and ninth centuries CE and existed for centuries thereafter with centralized bureaucratic control defined over territory and administrative capacity to tax their populations, field large militaries, and provide extensive public goods. They created these institutions not to wage war or suppress revolt: the longevity of dynasties in these countries is evidence of both the peacefulness of their region and their internal stability. Rather, Korea and Japan developed state institutions through emulation and learning from China. The elites of both copied Chinese civilization for reasons of prestige and domestic legitimacy in the competition between the court and the nobility.

AbstractAlpha-lactalbumin (α-LA) and β-lactoglobulin (β-LG) are contained in bovine milk whey. Chemical and physical treatments are known to alter the conformation of these proteins and we have previously reported that α-LA denatured with trifluoroethanol (TFE) and isolated from sterilized market milk inhibited the growth of rat crypt IEC-6 cells. In the present study, we aimed to evaluate the effects of TFE-treated α-LA and β-LG on cell growth using cultured intestinal cells and on their safety using a suckling mouse model. First, we investigated the effect of the TFE-treated whey proteins on human colonic Caco-2 cells at various differentiation stages. In the undifferentiated stage, we assessed cell growth by a water-soluble tetrazolium-1 method. The native whey proteins enhanced cell proliferation, whereas the TFE-treated whey proteins strongly inhibited cell growth. We investigated cell barrier function in the post-differentiated stage by measuring transepithelial electrical resistance (TER). Not only native but also the TFE-treated whey proteins increased TER. Next, we evaluated whether the TFE-treated α-LA and β-LG have adverse effects on healthy suckling mice. No mice given by the TFE-treated samples showed any adverse symptoms. We also performed a safety test using a human rotavirus infected gastrointestinal disease suckling mice model. Even the TFE-treated whey proteins appeared to prevent the development of diarrheal symptoms without any adverse effects. Although we cannot know the effect of long-term ingestion of denatured whey proteins, these results suggest that they have no adverse effects on differentiated intestinal cells and digestive tract, at least in short-term ingestion.
Why knowledge is the best way to reduce the risks associated with raw milk and raw milk products

Published: May 2021

AbstractIn an age of flexible conditions about mandatory milk pasteurisation, this opinion-based research reflection supports the view that the knowledge and the awareness of milk-borne infections are key requirements to decrease the risks associated with raw milk. Providing an analysis of the current potential risks related to consumption of raw milk and raw milk products, we discuss the main reasons to continue to be vigilant about milk-borne pathogens and the current scenario in relation to the formal and clandestine sale of raw milk. Finally, we select some highly effective strategies to reduce the risks associated with raw milk in food services. Regardless of whether a country regulation allows or prohibits the trade of raw milk and its products, this is not the time to be negligent.

Published: May 2021

AbstractObjectiveThis review assesses regenerative medicine of the upper aerodigestive tract during the first two decades of the twenty-first century, focusing on end-stage fibrosis and tissue loss in the upper airways, salivary system, oropharynx and tongue.MethodPubMed, Embase, Google Scholar, Cochrane Library, Medline and clinicaltrials.org were searched from 2000 to 2019. The keywords used were: bioengineering, regenerative medicine, tissue engineering, cell therapy, regenerative surgery, upper aerodigestive tract, pharynx, oropharynx, larynx, trachea, vocal cord, tongue and salivary glands. Original studies were subcategorised by anatomical region. Original human reports were further analysed. Articles on periodontology, ear, nose and maxillofacial disorders, and cancer immunotherapy were excluded.ResultsOf 716 relevant publications, 471 were original studies. There were 18 human studies included, within which 8 reported airway replacements, 5 concerned vocal fold regeneration and 3 concerned salivary gland regeneration. Techniques included cell transplantation, injection of biofactors, bioscaffolding and bioengineered laryngeal structures.ConclusionModerate experimental success was identified in the restoration of upper airway, vocal fold and salivary gland function. This review suggests that a shift in regenerative medicine research focus is required toward pathology with a higher disease burden.

AbstractIn this paper I offer a philosophical analysis of the act of ‘liking’ a post on social media. First, I consider what it means to ‘like’ something. I argue that ‘liking’ is best understood as a phatic gesture; it signals uptake and anoints the poster’s positive face. Next, I consider how best to theorise the power that comes with amassing many ‘likes’. I suggest that ‘like’ tallies alongside posts institute and record a form of digital social capital. Finally, I consider whether ‘likes’ have ultimately improved online discourse. I argue that while the ‘liking’ function itself is relatively innocuous, public ‘like’ tallies introduce a corrosive motivation to online communication. By making the prospect of increased social capital perpetually salient to us, they encourage us to prioritise high levels of engagement over meaningful engagement.
Surveillance Capitalism: a Marx-inspired account
Authors: Venkatesh Nikhil 
Published: May 2021

AbstractSome of the world's most powerful corporations practise what Shoshana Zuboff (2015; 2019) calls ‘surveillance capitalism’. The core of their business is harvesting, analysing and selling data about the people who use their products. In Zuboff's view, the first corporation to engage in surveillance capitalism was Google, followed by Facebook; recently, firms such as Microsoft and Amazon have pivoted towards such a model. In this paper, I suggest that Karl Marx's analysis of the relations between industrial capitalists and workers is closely analogous to the relations between surveillance capitalists and users. Furthermore, three problematic aspects of industrial capitalism that Marx describes – alienation, exploitation and accumulation – are also aspects, in new forms, of surveillance capitalism. I draw heavily on Zuboff's work to make these parallels. However, my Marx-inspired account of surveillance capitalism differs from hers over the nature of the exchange between users and surveillance capitalists. For Zuboff, this is akin either to robbery or the gathering of raw materials; on the Marx-inspired account it is a voluntary sale. This difference has important implications for the question of how to resist surveillance capitalism.
Income poverty among children with a disability in Belgium: the interplay between parental employment, social background and targeted cash support
Authors: VINCK JULIE 
Published: May 2021

AbstractPrevious research has shown a clear link between childhood disability and child poverty. This is related to the fact that parents of disabled children (1) need to provide more care, which impedes their employment participation; and (2) more often belong to disadvantaged social categories. However, the adverse relationship between childhood disability and child poverty can be cushioned by cash support systems. Hitherto, the literature lacks insight into how the receipt of different cash support systems is related to parental employment and social background, and what joint role these three factors play in understanding the poverty risk of these children. To fill this gap, a case study on Belgium is performed using unique and large-scale register data. The results show that disabled children have a lower income poverty risk than non-disabled children, even when parental employment and social background are taken into account. This can be explained by the targeted cash support disabled children receive. However, previous research showed that a substantial group of disabled children does not receive the benefit. Hence, more could be achieved if the non-take-up would be addressed, in particular among the most vulnerable children.
