What can supraspecies richness tell us?

Biogeographers, ecologists, palaeontologists, and conservation managers often deal with checklists in which not all individuals have been identified to a species level, or the accuracy of species identification is questionable. Is it possible and credible to investigate species richness based on such checklists? Studies on macrofauna in the Far Eastern seas, eastern Arctic seas, and adjacent waters of the Pacific and Arctic Oceans suggest that in different habitats and for diverse taxa, species, and higher taxa richness strongly correlate with each other and increase with an expansion in the study area and sample size according to the species–area law. Such an increase is higher in the bottom zone than in the pelagic. Species and higher taxa richness also show a decrease from lower to higher latitudes, which is in line with the Humboldt–Wallace’s law. According to Willis’ law and self-similarity in the organisation of taxonomic levels, species richness can be assessed based on the genus, family, and order richness. In other words, supraspecies richness itself can tell us the same as species richness and therefore certain global patterns revealed at the species level may also be revealed at the supraspecies level. Such a concordance in general trends among richness parameters at different taxonomic levels in practice implies that species richness can be studied based on lists that lack species identifications or lists with doubtful species identification. We suggest bolder use of supraspecies richness in science and practice, discussing the disadvantages and advantages of this approach.     

The role of contextual factors in the electoral resurgence of extreme right-wing forces in Spain: The case of Andalusia

Up until the end of 2018, extreme right-wing parties and their anti-immigration discourse, now a common occurrence in other European countries, had not appeared on the Spanish political scene. However, in December of that year, the Spanish extreme right-wing party VOX reversed this trend and made significant electoral gains in the Andalusian regional elections. This phenomenon has led us to analyse, in this study, the role played by contextual factors (i.e., out-group size, territorial concentration of the immigrant population, demographic change in settlement locations, aggregated educational level and unemployment rate among the receiving society) in the rise in the number of VOX voters. To achieve this, VOX's results from all the polling stations in Andalusia contained in its 5946 census tracts were analysed. At the same time, each census tract was associated with its demographic, economic and educational data, and their relationship was analysed using a multilevel analysis with Mplus. The results show that the presence of economic immigrants is indeed associated with a higher percentage of VOX voters in Andalusia. However, despite this general trend, those census tracts with a high territorial concentration of Maghrebi immigrants are associated with a lower percentage of support for this extreme right-wing party. The opposite is found for Romanian immigrants. Moreover, areas with larger percentages of people with a high level of education influenced greater support for VOX. Thus our findings suggest the traditional explanations for the increased support for extreme right-wing parties in northern Europe do not provide clear patterns that can be extrapolated to Andalusia.     

The bodies of others in Swedish feminism

Abstract

The body – or, more specifically, women’s bodies – has long been one of feminism’s central topics. This discussion has ranged from explorations of the cultural meaning of biology to the challenging of classification systems regulating bodies not only culturally coded as female or male but also understood through race regimes. This article seeks to explore the location of bodies within Swedish feminism, examining how women’s bodies are understood, designated and acted upon in feminist agendas. Our focus is on the location that bodies take in political conflicts among and between feminists. In particular, we explore the impact of the presence of black bodies within the field of Swedish feminism. On a theoretical level, this article bridges decolonial feminist contributions of Black, Chicano and Latin American feminist thought on the body. The research methodology combined autoethnography with feminist ethnography, including an analysis of 25 narratives of young feminist activists engaged in public resistance against, and confrontation with, the growing presence of right-wing xenophobic social movements and political parties in the public sphere.     

Urban size and KIBS vertical disintegration: the case of Milan

The literature shows that market size favours firms’ vertical disintegration because it reduces transaction and knowledge coordination costs. The existing evidence is based primarily on cross-sectional data and on the manufacturing sector, with little or no attention is given to longitudinal data and services. This paper estimates the effect of urban size on the purchase of service inputs by knowledge-intensive business service firms located in the metropolitan region of Milan. Relying on a rich panel dataset, and adopting different econometric techniques to overcome endogeneity, we find a positive and statistically significant effect of increased urban population on the degree of KIBS vertical disintegration only when urban size is measured at the province level. We also find that this effect holds particularly in the case of traditional professional- rather than technology-related activities.     

新中国土地改革后新富农产生的规模与分布研究

从土地改革结束到农业集体化高潮前夕,新富农的出现从全国范围来看是稀少而缓慢的。在各省之间,农民的富裕程度与新富农比重大小关系不明显,但在同一地区内来看,两者呈现正相关关系。同时,在农业合作化程度较高亦即是较早对新富农采取限制政策的地区,新富农的比重并不一定低于甚至高于其他地区。这说明多种因素对新富农的产生、发展发生作用,单因素的分析不能解释清楚新富农这个复杂的社会经济问题。     

Osteoarthritis and body mass

Osteoarthritis is the second most common pathology found in anthropological collections. Although a great deal is known about osteoarthritis, it is not yet known whether in skeletal populations there is a correlation between osteoarthritis and body mass. In this study, lower limb and spinal osteoarthritis scores were taken to determine whether body mass and femoral length correlate with osteoarthritis on weight bearing joints. Osteoarthritis was measured using a four-point ordinal scale on a sample of 114 adult prehistoric Californian Amerinds. Body mass was calculated from femoral head breadth; femoral length was measured using standard procedures; and age and sex were determined through standard osteological procedures. Using Spearman correlations, body mass and femoral length did not correlate significantly with any of the osteoarthritis variables. Age correlated significantly with nearly all of the osteoarthritis variables (hip, r = 0.507; knee, r = 0.528; cervical, r = 0.513; thoracic, r = 0.647; lumbar, r = 0.507, P-values < 0.001); and body mass and femoral length correlated with sex (r-values = 0.835 and 0.654, P-values < 0.001). With age and sex controls, body mass negatively correlated with the hip osteoarthritis variable (r = −0.202, P < 0.05), but not with any of the other osteoarthritis variables. Results concur with previous findings in the anthropological literature and highlight complexities of osteoarthritis etiology.     

Does size of local labour markets affect wage inequality? a rank-size rule of income distribution

The questions addressed in this paper are: (i) does wage inequalityincrease with local population size, and if so, (ii) what arepossible factors behind this increase? In a cross-section analysisof Swedish local labour markets using unique full populationdata, the article shows that urban scale, i.e. size of localpopulation, has significant positive effects on wage inequality.Testing for potential explanations, labour market diversification,human capital, migration, age structure and employment are shownto be significantly associated with inequality. Given theseeffects, the article raises the question of how to understandand incorporate scale effects into models of long-term changein wage inequality.     

The fractal geometry of ancient Maya settlement

Ancient Maya settlement patterns exhibit fractal geometry both within communities and across regions. Fractals are self-similar sets of fractional dimension. In this paper, we show how Maya settlement patterns are logically and statistically self-similar. We demonstrate how to measure the fractal dimensions (or Hausdorff–Besicovitch dimensions) of several data sets. We describe nonlinear dynamical processes, such as chaotic and self-organized critical systems, that generate fractal patterns. As an illustration, we show that the fractal dimensions calculated for some Maya settlement patterns are similar to those produced by warfare, supporting recent claims that warfare is a significant factor in Maya settlement patterning.     

Human corpse manipulation and the body as symbol: A case study from the Eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene

Human body manipulation and secondary burials are widespread funerary practices in many areas of the world. The archaeology of the Pampas and North-Eastern Patagonia, Argentina, is no exception. In this paper, archaeological case studies from the lower basin of the Colorado River during the Final Late Holocene (ca. 1000–250 years BP) are presented and discussed. Secondary burials were recovered that indicated an intentional manipulation of bodies. Evidences of cut marks and the coloring of bone surfaces were recorded. The bundles were composed of individuals of both sexes and diverse age categories. The Pampean region and North-Eastern Patagonia witnessed significant hunter–gatherer population dynamics during the last 1000 years BP. Climatic, ecologic, demographic, and economic explanations have been proposed as the background to these changes. In this paper, it is argued that accompanying these factors, as part of a broader socio-cultural scenario, were significant social interaction networks and processes of social complementarity between groups. In this context, it is proposed that the complexity observed in relation to the handling of bodies is part of a worldview in which the body was seen as material culture – as a symbol – that played an important role for the community in group identity maintenance in a cultural context undergoing significant organizational changes.     

8500-year-old Late Mesolithic garment embroidery from Vlasac (Serbia): Technological,use-wear and residue analyses

This paper presents results of contextual, technological, use-wear and residue analyses of body ornaments from two Late Mesolithic burials recently excavated at the site of Vlasac in the Danube Gorges of the central Balkans. Common to both burials are ornaments made from modified and unmodified carp (Cyprinidae sp.) pharyngeal ‘teeth’ along with Cyclope neritea marine gastropods. Experimental and low and high magnification use-wear approaches have been employed in reconstructing the way these ornaments were made and used. The precise contextual distribution of these ornaments has been recorded for the first time. The two examined burials exhibit a number of similarities, particularly in the way ornaments were placed in relation to the body. Both burials are also contemporaneous, dated to the mid-7th millennium BC. Implications of these findings for Mesolithic foragers' corporeal symbolism, group identity and regional and long-distance acquisition networks are briefly examined.
