One size doesn’t fit all: a thematic analysis of interviews with people who have stopped participating in Narcotics Anonymous in Norway
2020
Abstract Background For persons with substance use disorders (SUDs), 12-step groups (TSGs) are the most available and used peer-based recovery resource, worldwide. However, disengagement is common, and attrition may partly be due to practices and procedures within these groups that are unacceptable to a portion of the population with SUDs. Our overall aim was to identify problematic issues related to Narcotics Anonymous (NA) participation in Norway, to inform addiction professionals’ strategies when referring persons to addiction-related self-help groups (SHGs). Methods In this qualitative study, we interviewed ten individuals who had previously participated regularly in NA for at least 6 m…
Maternal Iodine Status During Pregnancy Is Not Consistently Associated with Attention-Deficit Hyperactivity Disorder or Autistic Traits in Children
2020
Background: Severe iodine deficiency during pregnancy can cause intellectual disability, presumably through inadequate placental transfer of maternal thyroid hormone to the fetus. The association between mild-to-moderate iodine deficiency and child neurodevelopmental problems is not well understood. Objectives: We investigated the association of maternal iodine status during pregnancy with child attention-deficit hyperactivity disorder (ADHD) and autistic traits. Methods: This was a collaborative study of 3 population-based birth cohorts: Generation R (n = 1634), INfancia y Medio Ambiente (n = 1293), and the Avon Longitudinal Study of Parents and Children (n = 2619). Exclusion criteria were…
The transition between the Late Bronze Age and the Phoenician world in Malta
1998
This article tries to shed some more light on the final chronology of the Late Bronze Age and also about the possible coexistence and mutual cultural influences between the indigenous world and the first Phoenician settlers in Malta.
Polysaccharide remains in Maya mural paintings: is it an evidence of the use of plant gums as binding medium of pigments and additive in the mortar?
2020
A number of monosaccharides characteristic of plant gums were found in paint layers and preparation layers of samples of Maya mural paintings of 10 archaeological sites located in Campeche and Yucatan regions. This finding opens the question about the deliberate use of these organic polymers as additives for improving workability and mechanical properties in the preparation layer mortar and conferring cohesion to the pigments in the paint layer. The study performed by GC-MS has confirmed the presence, in significant amounts, of a series of monosaccharides, being glucose and mannose between the most abundantly found. Nevertheless, the low amount present in most of the samples hindered the qu…
Leggere il diritto nella prospettiva del genere e viceversa

Il contributo illustra uno dei filoni tematici del volume di O. Cavallar e J. Kirshner, ovvero il ruolo del genere nell���ordine giuridico, e sottolinea l���importanza del diritto per affrontare la storia delle identit�� di genere e soprattutto per promuovere la storia della mascolinit��.
Chlorine as a Discriminant Element to Establish the Provenance of Central Mediterranean Obsidians
2020
Abstract Chlorine is a minor element present in obsidians in quantities greater than in average igneous rocks. The chlorine concentration in obsidians is generally low, of the order of tenths of wt %, but it exhibits an appreciable differentiation among geological sources. Despite these characteristics, chlorine has rarely been taken into consideration as a possible indicator of obsidian provenance and it does not appear in the chemical analytical tables accompanying the geochemical characterisation of obsidian samples. In this work, after an overview of chlorine geochemistry and cycle, we present thirty-one new electron microprobe (EPMA) analyses, including Cl, of geologic obsidians sample…
Middle Palaeolithic flint procurement in Central Mediterranean Iberia: IMplications for human mobility.
2014
Different flint types from the Middle Palaeolithic site of Abrigo de la Quebrada (Chelva, Valencia) are characterized, both macro- and microscopically, and compared with types found at other localities in the region. Although procurement predominantly concerned the immediate vicinity of sites, our results show the presence of the same types in assemblages separated by distances of up to 120 km. The long distances involved are suggestive of a pattern of North-South mobility of human groups along the coastline of central Mediterranean Iberia.
Potes meleiros e colmenas em cerâmica: una tradicâo milenar
2006
Neste estudo apresenta-se uma breve resenha sobre a importância do mel na antiguidade e destaca-se a existência de contentores destinados ao seu armazenamento. Tendo em conta a maior antiguidade destes contentores recolhidos na Península (datáveis, pelo menos, a partir de c. de 600 a.C.), a sua persitência ao longo dos tempos, e a existência de paralelos etnográficos ainda hoje documentados, admitimos tratar-se de uma tradicâo com origem da Península.Destaca-se, ainda, a importância dos mellaria na economia do mundo antigo e realça-se a identificacâo de colmeias em cerâmica na regiao de Valência e de uma inédita recolhida em Bracara Augusta, uma cidade romana localizada no extremo ocidente …
Climate change and population dynamics during the late Mesolithic and the Neolithic transition in Iberia
2009
This paper explores how Early Holocene climate changes in the Western Mediterranean would have affected Late Mesolithic settlement distribution and subsistence strategies in Iberian Peninsula, thereby giving rise to various adaptive scenarios. The current radiocarbon data set concerning the Neolithisation process has revealed the rapidity of the spread of farming in Iberia. Considering both the implications of the last hunter-gatherers’ adaptation strategies and the population dynamics of agro-pastoral communities, we address the migration patterns underlying the Mesolithic- Neolithic transition. In conclusion, we propose that the initial colonization process was the result of two successiv…
Documentación 3D de abrigos rupestres a partir de láser escáner y de procesos fotogramétricos automatizados
2013
[EN] Metric and graphic documentation of archaeological cultural heritage requires effective solutions for archiving, visualization, analysis, management, and monitoring of different monuments and sites. This paper presents the geomatic workflow undertaken on a singular rock art site, Coves de la Saltadora. The cave is part of the Rock Art of the Mediterranean Basin on the Iberian Peninsula declared World Heritage Site by UNESCO in1998. The different steps are reviewed, starting from the data acquisition until the final delivery of part of the metric outputs such as 3D models, photorealistic models, orthophoto mosaics in two levels, general and detail.
