Internalizing Problems in Adopted Eastern European Adolescents: The Role of the Informant, Early Adversity and Post-Adoption Processes / Problemas Internalizantes en Adolescentes Adoptados de Europa del Este: el Rol del Informante, la Adversidad Temprana y los Procesos Post-adopción

Background: Internationally adopted children who suffered early institutionalization are at risk of a late onset of internalizing problems in adolescence. Both pre-adoption, adversity-related, and post-adoption factors predict variability in internalizing problems in this population. Previous studies have suggested different patterns of parent- adolescent informant discrepancies in adoptive dyads. Method: We analyzed internalizing problems among 66 adolescents internationally adopted from Russia to Spanish families using both the parent- and self-report version of the Strengths and Difficulties Questionnaire and comparing them with a low-risk, community group (n = 30). We assessed pre-adoption and post-adoption factors and evaluated cross-informant discrepancies. Results: Internationally adopted adolescents exhibited more internalizing problems by parent-report than community adolescents, but there were no differences by self-report. Adopted youth showed no discrepancies between parent and self-report, whereas community adolescents reported more internalizing symptoms than their parents. Pre-adoption adversity-related factors predicted parent-reported internalizing problems, while post-adoption factors predicted self-reported internalizing problems. Conclusions: Parent-adolescent informant discrepancies in adopted adolescents from Eastern Europe for internalizing symptoms were lower than in community adolescents. Both adversity-related factors and the lived experience of adoption may influence the development of internalizing symptoms in internationally adopted adolescents.(AU)

Antecedentes: Los niños y niñas adoptados internacionalmente están en riesgo de desarrollar problemas emocionales en la adolescencia. Factores relacionados con la adversidad y con procesos post-adopción predicen variabilidad en problemas internalizantes en esta población. Estudios previos sugieren también diferentes patrones de discrepancias entre informantes en diadas adoptivas. Método: Analizamos los problemas internalizantes en 66 adolescentes adoptados de Rusia a familias españolas, usando el Cuestionario de Capacidades y Fortalezas y comparándoles con un grupo adolescentes de la comunidad (n = 30). Evaluamos factores pre- y post-adopción y discrepancias entre informantes (autoinforme e informe parental). Resultados: Los adolescentes adoptados mostraron más problemas internalizantes por informe parental que los adolescentes comunitarios, pero no hubo diferencias por autoinforme. En el grupo adoptado no hubo discrepancias entre informantes, mientras que el grupo de comparación reportó más síntomas internalizantes que sus progenitores. Factores relacionados con la adversidad predijeron problemas internalizantes por informe parental, mientras que factores post-adopción predijeron problemas internalizantes por autoinforme. Conclusiones: Las discrepancias entre informantes en problemas internalizantes fueron menores en adolescentes adoptados que en adolescentes de la comunidad. Tanto factores relacionados con laadversidad como con la vivencia de la adopción pueden influir en el desarrollo de problemas internalizantes en adolescentes adoptados internacionalmente.(AU)

Upper Palaeolithic ritualistic cannibalism at Gough's Cave (Somerset, UK): The human remains from head to toe.

A recurring theme of late Upper Palaeolithic Magdalenian human bone assemblages is the remarkable rarity of primary burials and the common occurrence of highly-fragmentary human remains mixed with occupation waste at many sites. One of the most extensive Magdalenian human bone assemblages comes from Gough's Cave, a sizeable limestone cave set in Cheddar Gorge (Somerset), UK. After its discovery in the 1880s, the site was developed as a show cave and largely emptied of sediment, at times with minimal archaeological supervision. Some of the last surviving remnants of sediment within the cave were excavated between 1986 and 1992. The excavations uncovered intensively-processed human bones intermingled with abundant butchered large mammal remains and a diverse range of flint, bone, antler, and ivory artefacts. New ultrafiltrated radiocarbon determinations demonstrate that the Upper Palaeolithic human remains were deposited over a very short period of time, possibly during a series of seasonal occupations, about 14,700 years BP (before present). The human remains have been the subject of several taphonomic studies, culminating in a detailed reanalysis of the cranial remains that showed they had been carefully modified to make skull-cups. Our present analysis of the postcrania has identified a far greater degree of human modification than recorded in earlier studies. We identify extensive evidence for defleshing, disarticulation, chewing, crushing of spongy bone, and the cracking of bones to extract marrow. The presence of human tooth marks on many of the postcranial bones provides incontrovertible evidence for cannibalism. In a wider context, the treatment of the human corpses and the manufacture and use of skull-cups at Gough Cave have parallels with other Magdalenian sites in central and western Europe. This suggests that cannibalism during the Magdalenian was part of a customary mortuary practice that combined intensive processing and consumption of the bodies with ritual use of skull-cups.

A new Lower Pleistocene archeological site in Europe (Vallparadis, Barcelona, Spain).

Here we report the discovery of a new late Lower Pleistocene site named Vallparadís (Barcelona, Spain) that produced a rich archeological and paleontological sequence dated from the upper boundary of the Jaramillo subchron to the early Middle Pleistocene. This deposit contained a main archeological layer with numerous artifacts and a rich macromammalian assemblage, some of which bore cut marks, that could indicate that hominins had access to carcasses. Paleomagnetic analysis, electron spin resonance-uranium series (ESR-US), and the biostratigraphic chronological position of the macro- and micromammal and lithic assemblages of this layer reinforce the proposal that hominins inhabited Europe during the Lower Pleistocene. The archeological sequence provides key information on the successful adaptation of European hominins that preceded the well-known fossil population from Atapuerca and succeeded the finds from Orce basin. Hence, this discovery enables us to close a major chronological gap in the early prehistory of Iberia. According to the information in this paper and the available data from these other sites, we propose that Mediterranean Western Europe was repeatedly and perhaps continuously occupied during the late Matuyama chron.

The first hominin of Europe.

The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains. Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithic tools and faunal remains bearing traces of hominin processing, in stratigraphic level TE9 at the site of the Sima del Elefante, Atapuerca, Spain. Level TE9 has been dated to the Early Pleistocene (approximately 1.2-1.1 Myr), based on a combination of palaeomagnetism, cosmogenic nuclides and biostratigraphy. The Sima del Elefante site thus emerges as the oldest, most accurately dated record of human occupation in Europe, to our knowledge. The study of the human mandible suggests that the first settlement of Western Europe could be related to an early demographic expansion out of Africa. The new evidence, with previous findings in other Atapuerca sites (level TD6 from Gran Dolina), also suggests that a speciation event occurred in this extreme area of the Eurasian continent during the Early Pleistocene, initiating the hominin lineage represented by the TE9 and TD6 hominins.

Evidence for bronze age cannibalism in El Mirador Cave (Sierra de Atapuerca, Burgos, Spain).

During excavations of the Bronze Age levels at El Mirador Cave, a hole containing human remains was found. Taphonomic analysis revealed the existence of cutmarks, human toothmarks, cooking damage, and deliberate breakage in most of the remains recovered, suggesting a clear case of gastronomic cannibalism. The piled distribution of the remains, the uneven skeletal representation, and the chronological difference between the pit and the remains suggest that these bones were subsequently buried by a human group that inhabited into the cave later in time. Evidence of gastronomic cannibalism has already been documented in Gran Dolina, another site in the Sierra de Atapuerca, on remains of Homo antecessor with an age of 800 ky (Fernández-Jalvo et al.: Science 271 (1996) 277-278; Fernández-Jalvo et al.: J Hum Evol 37 (1999) 591-622).

Late survival of Neanderthals at the southernmost extreme of Europe.

The late survival of archaic hominin populations and their long contemporaneity with modern humans is now clear for southeast Asia. In Europe the extinction of the Neanderthals, firmly associated with Mousterian technology, has received much attention, and evidence of their survival after 35 kyr bp has recently been put in doubt. Here we present data, based on a high-resolution record of human occupation from Gorham's Cave, Gibraltar, that establish the survival of a population of Neanderthals to 28 kyr bp. These Neanderthals survived in the southernmost point of Europe, within a particular physiographic context, and are the last currently recorded anywhere. Our results show that the Neanderthals survived in isolated refuges well after the arrival of modern humans in Europe.
