Cultural evolution and environmental change in Central Europe between 40 and 15 ka
2020
The role of environmental change in the evolution of cultural traits is a topic of long-standing scientific debate with strongly contrasting views. Major obstacles for assessing environmental impacts on the evolution of material culture are the fragmentary nature of archaeological and – to a somewhat lesser extent – geoscientific archives and the insufficient chronological resolution of these archives and related proxy data. Together these aspects are causing difficulties in data synchronization. By no means does this paper attempt to solve these issues, but rather aims at shifting the focus from demonstrating strict chains of causes and events to describing roughly contemporaneous developm…
Iberian Neolithic Networks: The Rise and Fall of the Cardial World
2017
Recent approaches have described the evolutionary dynamics of the first Neolithic societies as a cycle of rise and fall. Several authors, using mainly c14 dates as a demographic proxy, identified a general pattern of a boom in population coincident with the arrival of food production economies followed by a rapid decline some centuries afterwards in multiple European regions. Concerning Iberia, we also noted that this phenomenon correlates with an initial development of archaeological entities (i.e., ‘cultures’) over large areas (e.g. the Impresso-Cardial in West Mediterranean), followed by a phase of ‘cultural fragmentation’ by the end of Early Neolithic. These results in a picture of high…
paco: implementing Procrustean Approach to Cophylogeny in R
2017
Summary The concordance of evolutionary histories and extant species interactions provides a useful metric for addressing questions of how the structure of ecological communities is influenced by macro-evolutionary processes. We introduce paco (v0.3.1), an R package to perform Procrustean Approach to Cophylogeny. This method assesses the phylogenetic congruence, or evolutionary dependence, of two groups of interacting species using both ecological interaction networks and their phylogenetic history. We demonstrate the functionality of paco through its application to empirical host-parasite and plant-pollinator communities. Although the package is intended to assess the phylogenetic congruen…
The Neolithic Transition in the Baltic Was Not Driven by Admixture with Early European Farmers
2017
Summary The Neolithic transition was a dynamic time in European prehistory of cultural, social, and technological change. Although this period has been well explored in central Europe using ancient nuclear DNA [1, 2], its genetic impact on northern and eastern parts of this continent has not been as extensively studied. To broaden our understanding of the Neolithic transition across Europe, we analyzed eight ancient genomes: six samples (four to ∼1- to 4-fold coverage) from a 3,500 year temporal transect (∼8,300–4,800 calibrated years before present) through the Baltic region dating from the Mesolithic to the Late Neolithic and two samples spanning the Mesolithic-Neolithic boundary from the…
Language teacher identities as socio-politically situated construction: Finnish and Brazilian student teachers’ visualisations of their professional …
2021
Abstract The process of envisioning the future is central to teachers’ identity construction, but different environments create distinct sociocultural conditions for the process. This qualitative study drawing on visual-textual methods compares Finnish and Brazilian student teachers’ desired and feared professional futures. Two different perspectives on future identities were detected: a desire for status and a desire for meaningfulness. The results revealed the radically different social status of teaching in the two countries and the role this played in the envisioned identities. The study highlights the importance of awareness of the socio-political nature of identity construction in dev…
Sociocultural Attitudes Towards Appearance Questionnaire-4: Psychometric properties among a French clinical eating disorder sample and normative comp…
2020
Although the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4) has been shown to be a reliable and valid tool for assessing appearance pressures and appearance ideal internalization among French college students, to date its psychometric properties among French clinical populations have not been examined. The aim of this study was to evaluate the factor structure, reliability, and validity of the SATAQ-4 among a French female clinical eating disorder sample, and to compare the mean SATAQ-4 scores from this clinical sample to previously published means observed among French female college women. The current sample included 192 French women consecutively recruited from an o…
On some difficulties of putting in dialogue animal rights with anthropological debates: a historical view in three episodes
2018
In this paper, I try to identify the reasons why the dialogue between sociocultural anthropology and animal rights theories and movements continues to be difficult and scarce. At first sight this weakness of communication is surprising, if one looks at the amount of anthropological studies on human/animal relationships, in most cases pointing to how animals are considered in many cultures as non- human subjects or persons. For understanding the roots of this state of affairs, I compare the ways anthropologists and animal rights theorists and activists have engaged with the issue of the differences and commonalities between human beings and nonhuman animals. For this aim, I contrast the sear…
Why being there mattered: Staged transparency at the International Criminal Court
2021
Abstract The International Criminal Court (ICC) represents a criminal justice setting exceptionally welcoming to discourse scholars. The court website provides ample information about ongoing cases, hearings are livestreamed, and transcripts, video footage, and other relevant documents are available online. Against this background of comprehensive transparency, this paper explores the additional value of physically attending ICC trial hearings. An auto-ethnography of how the ICC court landscape structures the visitor's path to the courtroom gallery, it is claimed, brings out the staged nature of the Court's projection of transparency. The ensuing discussion explicates the implications of th…
Psychometric properties of measures of sociocultural influence and internalization of appearance ideals across eight countries
2020
The aim of the current study was to examine the psychometric properties of two well-established measures of sociocultural influence and internalization of the thin/low body fat ideal and muscular ideal. Data from 6272 emerging adults (68.9 % female), aged 18-30 years from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. were included in this study. Participants completed measures of pressure from mother, fathers, peers, and media, to both increase muscles and lose weight, as well as internalization of the thin/low body fat ideal and muscular ideal. Overall, support for partial invariance was found across the scales. In addition, group level differences were found between…
The emergence and adaptive use of prestige in an online social learning task
2020
AbstractPrestige-biased social learning occurs when individuals preferentially learn from others who are highly respected, admired, copied, or attended to in their group. This form of social learning is argued to reflect novel forms of social hierarchy in human societies, and, by providing an efficient short-cut to acquiring adaptive information, underpin the cumulative cultural evolution that has contributed to our species’ ecological success. Despite these potentially important consequences, little empirical work to date has tested the basic predictions of prestige-biased social learning. Here we provide evidence supporting the key predictions that prestige-biased social learning is used …
