The After School Routines of Literature-Devoted Urban Children

This paper discusses the out of school routines of a group of ‘literature-devoted’ children of the city of Madrid (Spain). The children and families were recruited for the study at a library, a children's bookstore and a puppet show in a park. Participants provided information on their weekly routines through several procedures: surveys, photographs of their daily lives, interviews based on the photographs and interviews with parents. We develop a spatially based model that allows us to identify four styles of activity in children's out of school lives: homebound children, non-scheduled children, outdoor and scheduled children, and fully scheduled children. Our results suggest that there is significant diversity in the ways in which children's after-school time is organized, even within a middle-class and socially homogeneous sample as the one in this study. Also, the range of activities our participants engage in seems to contradict current portraits of Western urban children's lives as constrained.

Production and subsistence strategies at El Zafrín (Chafarinas Islands,Spain): new data for the early Neolithic of North-West Africa

Until a few years ago North-West Africa was ignored in our hypothesis on the neolithization of Western Mediterranean. Moreover, the few excavations focused exclusively on the test of stratigraphies in order to obtain chronological sequences. Recently developed archaeological projects allowed the inclusion of this region in the scientific debate on the origin and evolution of its Neolithic, on the contacts with the Iberian Peninsula through the Strait of Gibraltar, as well as on the documentation of ways of live, habitation structures, and economic strategies. The open area excavation of Zafrín, in the Chafarinas Isles – an archipelago located a short distance from the North African coast – and the full analysis of its lithic industry (technology, typology and use-wear), here presented, represents a novelty on the Neolithic research in North Africa. This in turn will permit us to approach subsistence strategies and the way of life developed by the Neolithic communities of the region.     

Determining the habitats of mollusk collection at the Sapelo Island shell ring complex, Georgia, USA using oxygen isotope sclerochronology

Sequential oxygen isotope analysis was performed on Mercenaria spp. (n = 41) and Crassostrea virginica (n = 17) valves excavated from the Sapelo Island Shell Ring complex, coastal Georgia, USA. The data were analyzed to determine the habitats in which the mollusks were harvested in order to gain insight into the subsistence practices of the site occupants. The rationale for this study is based on the observation that temperatures are similar in all of the habitats surrounding the island, but the δ¹⁸O_water trends across the habitats co-vary with salinity. Accordingly, the shells grown in these habitats contain sinusoidal oscillations in δ¹⁸O through ontogeny due primarily to seasonal temperature variation, but the absolute values reflect the salinity ranges of each habitat. Assuming a relatively constant oxygen isotope/salinity gradient since the time of site occupation, it appears that both of these mollusks were exploited over nearly the full range of their salinity tolerances. While a precise estimate of travel distance during collection cannot be made, these data suggest that mollusks were harvested at distances from the site greater than would be predicted using terrestrial foraging models. In addition to providing insight into past subsistence strategies in this region, this research establishes a new method of assessing catchment area and mobility practices.     

Paleoindian subsistence strategies and late Pleistocene paleoenvironments in the northeastern and southwestern United States: a tooth wear analysis

Paleoindians of North America entered a continent undergoing rapid climatic and environmental changes. This paper is a preliminary contribution toward obtaining a better picture regarding how climate and environmental change might have impacted the first settlers of North America. The Paleoindian sites we analyzed are, from the oldest to the youngest, Ingleside (Texas), Blackwater Draw Locality No. 1 (New Mexico), Hiscock Site (New York), and Plainview Quarry (Texas). Paleoenvironmental reconstruction involves identifying the dietary traits of ungulate species that might reflect the environmental conditions where they were living, and also where they might have been hunted by Paleoindians. Such an approach is realized through tooth microwear and mesowear analyses. Results indicate that a variety of food resources were available for the ungulates at these sites as well as the likely presence of mosaic environments around these sites which allowed Paleoindians to exploit resources in a large variety of habitats. The application of a method that allows for the estimation of the duration of occupation at archaeological sites reveals that results for Blackwater Draw and Hiscock Site indicate a long-term occupation of probably several months. However, during short events, Paleoindians were most likely hunting herds of horse and bison when these prey were available near the site. Results indicate that Plainview Quarry was likely used only for short-term occupations, with large game hunting focusing on bison. These patterns identified at the archeological sites studied are related to the fact that Paleoindians follow a high-technology forager model and frequently shifted their territory depending on the composition and distribution of the large mammal fauna.     

Les Pradelles (Marillac-le-Franc, France): A mousterian reindeer hunting camp?

The site of Les Pradelles has an important mousterian stratigraphic sequence. In the lower levels, the very low density of artefacts as well as the carnivores scavenging of carcasses abandoned by the neanderthals point to short-term human occupations; the introduction of finished tools (made on non-local, good quality flint) later highly curated, together with an expedient strategy on strictly local flint, suggest a task-specific location, within a low mobility pattern. The large faunal sample (mainly reindeer) underlines the preponderance of hunting activities. A range of butchering activities took place on the site and the abundance of filleting marks may be an indication of the processing of meat for transport to another settlement. The hypothesis of “specialized hunting” during Middle Palaeolithic is assessed with this new data set.     

三国西晋陵寝制度新论

三国西晋时期的陵寝制度呈现出诸多新动向,这些新动向远非过往学界所理解的"衰落"这么简单。曹魏、西晋陵寝制度大致沿着同一方向向前发展,墓祭、谒陵之风大为衰落,陵园建制简化的局面逐渐确立;同时,曹魏、西晋也在地下埋葬方面各自确立独具特色的等级标识。南方的孙吴政权在较多继承汉代传统的基础上,于下游上坊、采石二陵墓区内形成了较为明晰的等级秩序,却在中游的鄂州、武汉二陵墓区遭到了一定程度上的"僭越"。总体上,曹魏、西晋所确立的新动向,虽然被"永嘉之乱"中断,但还是对后来北方政权有一定影响。孙吴陵寝制度,则受限于自身政治军事环境,对当时统治区内部和后来的南方政权影响力均较为有限。

Children's out-of-home leisure activities: changes during the last decade in Norway

ABSTRACT

This study, based on two nationally representative samples of children aged 6–12 years and their parents from 2005 and 2013–2014, explores changes in children's play, through changes in participation in three different out-of-home leisure activities during the last decade in Norway as well as the interactions between these activities. The study finds that there has been an increase in the share of children who participate in organized leisure activities; that they start to participate at a younger age; and that the intensity of participation in organized leisure activities has increased. During the same period, there has been a decrease both in the extent of unsupervised play outdoors and in the degree to which children visit friends’ houses. A key empirical finding is that there is a strong positive association between participation in organized leisure activities and, respectively, the extent of unsupervised outdoor play and visits to friends.
