Holocene evolution and geoarchaeology in the Ebro valley around Zaragoza (Northern Spain).
No full textEvolution of slope, alluvial fan and filled valley systems related to the Alfocea Juslibol escarpment are analysed. Palaeogeographic and palaeoenvironmental
data obtained from this analysis can be useful in reconstructing the Upper
Holocene evolution of this sector of the Ebro valley. In the Alfocea, Miranda
and Señora filled valleys, a sequence of three sedimentary stages has been es tablished. Firstly, a well-developed stage, going from the Late Neolithic to the
Late Roman Age (3000 BCE – 4th century CE); a second, Medieval – Post Medieval epoch stage, and, finally, a more scarcely represented Recent stage.
These data can be compared with the available geoarchaeological information
from nearby areas in order to assess the climatic and/or human factors trigge ring the accumulation processes, as well as to evaluate the significance of the
lateral movement of the Ebro River

Previous issue date: 2007-01-22A sensibilidade ? uma interpreta??o consciente de est?mulos sensoriais do meio ambiente, e sua perda ou altera??o provoca perdas funcionais importantes. Este fato mostra a complexidade envolvida em mensurar um sistema que ainda n?o est? completamente definido. Muitos testes s?o popularizados para avaliar a sensibilidade da m?o e outros s?o descritos, embora nenhum tenha sido aceito, como padr?o-ouro, para avaliar a sensibilidade da m?o. Este estudo transversal tem como objetivo avaliar a reprodutibilidade interexaminador dos testes de monofilamentos de Semmes-Weinstein e Discrimina??o entre dois pontos est?tico e din?mico. Com tal finalidade, foram selecionados oitenta indiv?duos saud?veis com idade m?dia de 20,8 anos (desvio padr?o=3,5) que aceitaram participar do estudo. Esses indiv?duos foram submetidos ? aplica??o dos testes por dois examinadores distintos. Foi utilizado o coeficiente de kappa para avaliar a concord?ncia entre os examinadores para cada teste. Os testes de discrimina??o de dois pontos - est?tico e din?mico - n?o apresentaram uma concord?ncia estatisticamente significativa (p>0,05) e, no teste de monofilamentos, apesar do elevado percentual de concord?ncia entre os observadores, o c?lculo estat?stico do coeficiente kappa foi prejudicado pela aus?ncia de variabilidade dos dados. Pode-se concluir, ent?o, que os testes, em sua maioria, n?o apresentaram concord?ncia entre os examinadores, necessitando de novos estudos para confirmar estes achado
Geo-archaeological mapping using very high resolution and stereoscopic satellite imagery (Russian TK-350) integrated in a GIS: a case study for the Wadi Mujib area near Lehun (Jordan)
No full textA geo-archaeological model based on various environmental factors was developed for the Wadi Mujib area near the site of Lehun (Jordan). A DEM and a lithological map based on respectively a topographical and a geological map were prepared and integrated into a GIS. Since the geomorphology of the area is of primary, importance to archaeological site prediction an inventory of relevant relief information was extracted from a geomorphological map based on very high resolution and stereoscopic Russian TK350 images. These images offer an interesting alternative for conventional stereoscopic aerial photographs on scale 1:50,000 or smaller due to the high quality, the easy image processing, the large covered area, the availability and the sure and quick delivery,. After integration of the scanned geomorphological map the GIS finally comprised eight factor layers. A simple addition of these information layers resulted in a probability map for geo-archaeology showing the spatial variance of the probability, for archaeological evidence in the area. In the frame of the construction of a dam on the Wadi Mujib near the King's Highway the archaeologists can use this mop as a toot for organizing rescue research in a quick and efficient way
Evaluatie van Puinruimen, SOS en DAPPER
No full textIn recent years, an increase has been observed in restorative activities in the Dutch justice context that provide victims, offenders and other stakeholders with opportunities to respond to crimes in a personal manner and work on repairing material and intangible damage to, and between, parties. Restorative work with offenders in a detention setting is consistent with this development; the objective there is not primarily to bring offenders and victims together via mediation but to set in motion a process of awareness and restoration in offenders that have been convicted of a crime. This working method is also consistent with one of the pillars of the Dutch Custodial Institutions Agency (DJI) charged with the detention of convicted offenders: 'detention, restoration and prevention'. DJI is striving for a more restorative prison culture over the coming years: a more open and restorative climate in the institutions (among prisoners and staff) so that more and better opportunities are created for working in a victim-focused and restorative manner. In line with this objective, this study aims to evaluate three restorative courses, two of which have been provided in Dutch custodial institutions for several years: the Puinruimen course (since 2004) and SOS (since 2006) for adult prisoners. The third course is DAPPER, designed in 2012, for juvenile prisoners, rolled out at the national level in November 2015. Index Binnen het justitiedomein krijgen slachtoffers, daders en andere betrokkenen de laatste jaren meer mogelijkheden om op een persoonlijke wijze te reageren op misdrijven en te werken aan herstel van (im)materiele schade. Herstelgericht werken met daders binnen een detentieomgeving past in deze ontwikkeling. Hierbij is het doel om een bewustwordings- en herstelproces op gang te brengen onder daders die veroordeeld zijn voor een delict. Deze manier van werken sluit aan bij een van de pijlers van de Dienst Justitiële Inrichtingen (DJI) die in Nederland belast is met het detineren van strafrechtelijk veroordeelden: insluiten , herstellen en voorkomen. DJI streeft de komende jaren naar een meer herstelgerichte gevangeniscultuur: een meer open en herstelgericht klimaat in de inrichtingen (onder gedetineerden en het personeel), zodat er meer en betere mogelijkheden ontstaan om slachtoffer- en herstelgericht te werken. Ten behoeve van dit streven van DJI zijn er in dit onderzoek drie herstelgerichte cursussen geëvalueerd die worden gegeven in detentie: Puinruimen, SOS en DAPPER. Daarbij is in grote mate samengewerkt met ontwikkelaars, uitvoerders en andere betrokkenen bij deze cursussen. INHOUD: 1. Inleiding 2. Planevaluatie: methoden van onderzoek 3.

Drogadição na Adolescência: Família como Fator de Risco ou Proteção
No full textO uso de drogas na adolescência é um problema complexo e multifatorial que sofre influência de aspectos individuais, familiares, do grupo de pares e contextuais. A família tem sido um aspecto destacado na literatura, tanto pela importância em oferecer condições para um desenvolvimento saudável na adolescência quanto pela necessidade de participar de intervenções visando à superação de dificuldades. Este trabalho apresenta uma revisão sistemática de estudos que investigaram as relações entre o uso de drogas na adolescência e aspectos familiares. Foram consultadas duas bases de dados – Scielo e Redalyc– com as palavras de busca adolescência, drogadição e família. Foram selecionados 22 artigos, que foram analisados através de distribuições de frequência e análise de conteúdo. Os resultados indicaram que a família tem sido considerada como fator de risco ou de proteção para o uso de drogas na adolescência, conforme o modo como desempenha seu papel. Aspectos como o diálogo, o monitoramento familiar e o uso de drogas por amigos ou familiares são aspectos destacados na literatura. Em conclusão, salienta-se a importância da participação da família em intervenções de prevenção ou enfrentamento ao uso de drogas na adolescência
Dact-4 is a Xenopus laevis Spemann organizer gene related to the Dapper/Frodo antagonist of β-catenin family of proteins
No full textDact/Dapper/Frodo members belong to an evolutionarily conserved family of Dishevelled-binding proteins present in mammals, birds, amphibians and fishes that are involved in the regulation of Wnt and TGF-β signaling. In addition to the three established genes (Dact1-3) that compose the Dact family, a fourth paralogue group of related proteins has been recently identified and named Dact-4. Interestingly, Dact-4 is the most rapidly evolving gene of the entire family, as it displays very low homology with other Dact proteins and has lost key conserved domains. Dact-4 is not present in mammals, but weakly conserved homologs were found in reptiles and fishes. Recent RNAseq from our group identified new genes specifically expressed in the Xenopus laevis Spemann organizer. Among these, LOC100170590 mRNA encoded a protein sharing weak homology with a coelacanth Dact-like protein member. Here, by analyzing protein phylogeny and synteny, we show that this organizer gene corresponds to Dact-4. We report that Dact-4 is expressed in the Xenopus blastula pre-organizer region in addition to the gastrula organizer, as well as in placodes, eyes, neural tube, presomitic mesoderm and pronephros. Dact-4-Flag microinjection experiments suggest it is a nucleocytoplasmic protein, as are the other Dact paralogues
Geomorphological and archaeological aspects in the central Po Plain (northern Italy).
No full textThe comparison of geomorphological and archaeological data in some places of the central Po Plain allowed many fluvial forms to be dated and to reconstruct the evolution summarised as follows. Sector to south of the R. Po: i) from the Bronze Age to the late Middle Ages the R. Po flowed in a belt about 20 km wide, between the latitude 44° 54’ approx and its present position (latitude 45° 03’ approx); on the whole, the R. Po course has shifted from south to north; ii) the investigations indicate the shift to the east of the R. Secchia and to the west of the R. Panaro in the area downstream of Modena starting from the Bronze Age; iii) in the Modena city area, starting from the end of the Roman Age, an aggradational-type model of fluvial evolution was hypothesised. According to this model, the watercourses, even the minor ones, passed from a runoff occurring in deep riverbeds to one hanging over, or at least at the same level as, the surrounding plain.Sector to north of the R. Po, the area has been very stable during the whole Holocene: i) along the main palaeochannel of the R. Mincio, fed by ice melting from the Late Pleistocene Garda glacier, several Bronze Age settlements are identified; the settlements along the large palaeochannel fed by many springs; ii) some kilometres SE of Mantova city, along a large palaeochannel, a Neolithic settlement is singled out; in the same area Bronze age, Roman Age and Middle Age remnants are distributed on the same terrace surfac

Linking long-term gully and river channel dynamics to environmental change using repeat photography (Northern Ethiopia)
No full textIn the Highlands of Northern Ethiopia gully occurrence is linked to poverty-driven unsustainable use of the
land in a vulnerable semi-arid and mountainous environment, where intensive rainfall challenges the
physical integrity of the landscape. Trends in gully and river channel erosion, and their relation to triggering
environmental changes can proffer valuable insights into sustainable development in Northern Ethiopia. In
order to assess the region-wide change in gully and river channel morphology over 140 years, a set of 57
historical photographs taken in Tigray, and, clearly displaying gully cross-sections, were precisely repeated
from 2006 till 2009. Ninety-two percent of the gully and river sections (n=38) increased in cross-sectional
area during the studied period, especially after 1975. Two repeatedly photographed catchments of Lake
Ashenge and Atsela allowed a detailed study of gully development from 1936 until 2009. A conceptual
hydrogeomorphic model was devised for these catchments and validated for the Northern Ethiopian
Highlands. Three major phases can be distinguished in the hydrological regime of the catchments. In the first
phase, between 1868 (or earlier) and ca. 1965, the relatively stable channels showed an oversized
morphology inherited from a previous period when external forcing in environmental conditions had caused
the channels to shape. In the second phase (ca. 1965 – ca. 2000), increased aridity and continued vegetation
clearance accelerated the channel dynamics of the gully and river system. The third phase (ca. 2000 – present)
started after the large-scale implementation of soil and water conservation measures. In 2009, 23% of the gully
and river sections were stabilizing. This paper validates previous research indicating severe land degradation
in the second half of the 20th century. Additionally, it demonstrates that the recent erosive cycle started
around 1965 and, that at the present time, improved land management stabilizes headwater streams.sponsorship: This research was financed with the "Prize for Tropical Geography Yola Verhasselt" awarded by the Royal Academy of Overseas Sciences, Brussels, Belgium.
