In the s, the justice think tank proposed making sound recordings of all individuals held in police custody. The idea was set aside in the face of opposition, except for the questioning of minors who were the victims of sex offenses Sontag-Koenig, , for whom recording was not only authorized but made mandatory in It provided a first technological solution that was then repeated and extended to other situations: police custody of minor suspects, 23 then the questioning of individuals placed in police custody for a felony.

This provision was used as a standard attesting to the fact that it is no longer legally unthinkable that a trial can take place without all of the participants being physically present. Because it establishes a connection whereby images and sound are transmitted between two sites, providing for trials by videoconferencing could have been an opportunity to revive the debate on recording trials in general.

That did not happen, however. The discussion before the State Council regarding videoconferencing was so tense that the issue of recording hearings in general, which is technically possible, was omitted. The promoters did their best to prevent the issue from emerging — by assuring that videoconferencing would not be used for recording, which was prohibited by the act, modified in Thus, when the time came to regulate the practical terms for holding videoconferences between Paris and Saint-Pierre-et-Miquelon, a.

In this sense, therefore, videoconferencing constitutes an additional step toward undermining the prohibition to capture, record, and transmit trials. The classic public trial is a drama in which all the characters appear in the same place at the same time. The simultaneous presence of the various parties to the conflict gives the trial its meaning Garapon, Publicness is conceived of as the ability of citizens, members of the political community, to attend the trial.

Minjoz, They act as eyewitnesses to the trial and thereby give substance to the rule requiring that trials be public. The relaying of the trial by journalists, who are external third parties, is therefore superfluous. Firstly, some trials occur without co-presence, and the number of such trials is increasing. Secondly, for such trials to take place, they had to be made legal by changes in the law.

Legislative provisions that extended videoconferencing to all or almost all types of disputes have given remote appearance the same legal status as physical appearance. Physical attendance at trial has therefore become increasingly unnecessary and less important. The notion of a public hearing itself is therefore no longer exactly what it used to be. Consequently, the introduction of videoconferencing affects not only the state of the law, but also the institutional construct — in this instance, the standard of physical presence as the customary means of entering a full appearance at trial.

The other location — a library, a meeting room in another courthouse, or a fortiori a correctional facility — is not set up to accommodate the public. Attending a hearing therefore amounts to witnessing and being able to attest to only some of the circumstances under which it took place. What happens in the remote location cannot be seen except through what is shown on the screen; what happens outside the frame disappears, and what is in the frame is in fact staged by the act of framing itself type of shot, zooming, etc.

The witnesses are therefore captive to what is shown them. In practice, although connected by videoconferencing and jointly constituting the hearing, the two sites are undeniably governed by different rules regarding publicness. In this paper we have used the French experience to show that, in fact, the two activities share a number of features and tend to influence one another. Advocates promoted the implementation of videoconferencing by dodging the issue of recording — although audio and video recording was technically possible with videoconference devices.

In a sense, they neutralized the recording capability of cameras. Rather, they based their innovation on a legal argument centered on the precedent of videotaped testimonies already in force. But what is truly interesting is that the development of videoconferencing is indeed an indirect but concrete step toward weakening the impact of the main text a law modified by a act prohibiting the recording, filming and broadcasting of French hearings. The general principle remains written in the law as a general statement, but first, there are more and more exceptions for journalists and researchers and, further, a discrete exception — which could be a decisive one if it takes off — has been introduced with videoconferencing.

This calls for analyzing a variety of technologies that at first sight do not seem to be linked but which are intertwined at the empirical level. It also suggests that ancillary innovations — such as videoconferencing — are sometimes bound to cause major transformations in the concept of what constitutes a trial. In fact, whether hearings are filmed as part of conducting them or, as in our case, for research purposes, cameras are now authorized and accepted, and are sometimes even installed by the institution itself.

The more difficult issue, and one which continues to be an obstacle, is the use that will be made of the images once a media mindset, often presented as hard to square with the judicial mindset, takes hold.

Also our observed definite, but limited, Bronze Age influx resonates with the incomplete Indo-European linguistic conversion on the peninsula, although there are subsequent genetic changes in Iberia and defining a horizon for language shift is not yet possible.

This contrasts with northern Europe which both lacks evidence for earlier language strata and experienced a more profound Bronze Age migration. We used Cutadapt v. We estimated genomic coverage with Qualimap v2. In order to assess the level of contamination in ancient samples, we considered the number of mismatches in mtDNA haplotype defining mutations and determined the number of X-chromosome polymorphisms in male samples S2 Text [ 46 ]. We analysed aligned reads using mapDamage v2. We used the method published in reference [ 48 ] to determine the sex of the ancient individuals S2 Text , S2 Fig.

The genetic variation of ancient Eurasian genomes [ 2 , 4 , 5 , 11 , 14 — 21 , 23 , 53 — 56 ] was then projected onto the modern PCA lsqproject: YES option. Only ancient samples with a minimum of , pseudo-haploid calls were included. The dataset was also filtered for related individuals, and for SNPs with genotyping rate below A filter for variants in linkage disequilibrium was applied using the—indep-pairwise option in PLINK v1.

This resulted in a final , SNPs for analysis. The results for the best of these replicates for each value of K, i. Formal tests of admixture were implemented using D-statistics [ 58 ] and F-statistics [ 59 , 60 ] using the AdmixTools package version 4. We selected for genotype imputation relevant published samples that had been sequenced by whole-genome shotgun sequencing and for which coverage is above 0. In analysis I Fig 1 , imputed variants in 67 ancient Eurasian samples were filtered for posterior genotype probability greater or equal to 0.

In order to investigate the correlation between ancient ancestry in present-day populations and height genetic scores, we first calculated polygenic risk in Eurasian populations from the Human Origins dataset. This was followed by the estimation of the percentage ancestry of five distinct ancient populations EHG, CHG, WHG, Yamnaya, Anatolian Neolithic in the same dataset, which was done through the implementation of the F4 ratio method described in [ 60 ] using the Admixtools package version 4.

This table contains the individuals which were used to estimate the approximate percentage ancestry in modern populations of five ancestral groups who have contributed to western Eurasian variation, using an F4 ratio test Patterson The analysis is based on approximately , SNP positions. Moderns samples from the Human Origins dataset are represented in greyscale, with the exception of modern Iberians shown in green. Ancient samples are coloured by time depth and shaped according to geographic region.

Introduction Ancient genomics, through direct sampling of the past, has allowed an unprecedented parsing of the threads of European ancestry. Table 1 Summary of the samples sequenced in the present study. Open in a separate window. Fig 1. Increase in local hunter-gatherer ancestry in the Middle and Late Neolithic It has been previously shown that an individual CB13 dating from the very beginning of the Neolithic in Spain showed ancestry closer to a Hungarian hunter-gatherer KO1, found within a very early European Neolithic context than to the more western HGs from LaBrana in Spain and Loschbour in Luxembourg [ 18 ].

Fig 2. Patterns of hunter-gatherer haplotype donation to ancient Eurasians. Steppe-related introgression into the Portuguese Bronze Age Next, to further investigate this apparent shift between the Neolithic and Bronze Age in Iberia, we explored haplotype sharing patterns of ancient samples in the context of modern populations. Fig 3. Total variation distance between vectors of median haplotype donation from Bronze Age purple and Neolithic green samples from different regions in Europe to modern populations. Comparison of ancient samples from Portugal with ancient and modern individuals using directly observed haploid genotypes Bronze Age Y-Chromosome discontinuity Previous studies have demonstrated a substantial turnover in Y-chromosome lineages during the Northern European Late Neolithic and Bronze Age, with R1b haplogroup sweeping to high frequencies.

Extended haplotype homozygosity The role of positive selection in shaping diversity at specific loci in European populations has been of enduring interest and thus we tested whether our imputed genomes could directly reveal the imprint of adaptation in the past. Fig 6. Extended haplotype homozygosity in regions under selection. Discussion Our genomic data from 14 ancient individuals from 8 Portuguese archaeological contexts ranging from the Middle Neolithic to Middle Bronze Age throws light on how the two fundamental transitions in European prehistory affected populations at the Atlantic edge.
