A Reflective Encounter With the Fine Sand Area in a Nursery School Setting

This article draws on a model of reflection that involves creating meanings through repeated encounters with evocative objects. Responses to one such evocative object, a 20-second video clip of children playing in the fine sand area, illustrates the “turning toward” and then “turning away” from the object to engage with broader themes. Parten’s play types are used when analyzing children’s play in the fine sand area (the evocative object). The focus then turns away to themes of English as a second language, messy play, energies of childhood, and Foucault’s docile bodies. The intention was to integrate loosely formulated research aims relating to quality of the physical environment within the evolving life of the nursery setting to encourage a developing research orientation and reflective dis-position. This way of approaching practitioner research is well adapted to a longer-term engagement with enduring areas of interest, such as developing the potential of the physical environment.

Beach sand and the potential for infectious disease transmission: observations and recommendations

Recent studies suggest that sand can serve as a vehicle for exposure of humans to pathogens at beach sites, resulting in increased health risks. Sampling for microorganisms in sand should therefore be considered for inclusion in regulatory programmes aimed at protecting recreational beach users from infectious disease. Here, we review the literature on pathogen levels in beach sand, and their potential for affecting human health. In an effort to provide specific recommendations for sand sampling programmes, we outline published guidelines for beach monitoring programmes, which are currently focused exclusively on measuring microbial levels in water. We also provide background on spatial distribution and temporal characteristics of microbes in sand, as these factors influence sampling programmes. First steps toward establishing a sand sampling programme include identifying appropriate beach sites and use of initial sanitary assessments to refine site selection. A tiered approach is recommended for monitoring. This approach would include the analysis of samples from many sites for faecal indicator organisms and other conventional analytes, while testing for specific pathogens and unconventional indicators is reserved for high-risk sites. Given the diversity of microbes found in sand, studies are urgently needed to identify the most significant aetiological agent of disease and to relate microbial measurements in sand to human health risk.

Geology of the Sand Creek porphyry molybdenum prospect /

The Sand Creek Prospect is located within the eastern exposed margin of the Coast Plutonic Complex. The occurrence is a plug and dyke porphyry molybdenum deposit. The rock types, listed in decreasing age: 1) metamorphlc schists and gneisses; 2) diorite suite rocks - diorite, quartz diorite, tonalite; 3) rocks of andesitic composition; 4) granodiorites, coarse porphyritic granodiorite, quartzfeldspar porphyry, feldspar porphyry; and 5) lamprophyre. Hydrothermal alteration is known to have resulted from emplacement of the hornblende-feldspar porphyry through to the quartz-feldspar porphyry. Molybdenum mineralization is chiefly associated with the quartz-feldspar porphyry. Ore mineralogy is dominated by pyrite with subordinate molybdenite, chalcopyrite, covelline, sphalerite, galena, scheelite, cassiterite and wolframite. Molybdenite exhibits a textural gradation outward from the quartz-feldspar porphyry. That is, disseminated rosettes and rosettes in quartz veins to fine-grained molybdenite in quartz veins and potassic altered fractures to fine-grained molybdenite paint or 6mears in the peripheral zones. The quartz-feldspar porphyry dykes were emplaced in an inhomogeneous stress field. The trend of dykes, faults and shear zones is 0^1° to 063° and dips between 58° NW and 86* SE. Joint Pole distribution reflects this fault orientation. These late deformatior maxima are probably superimposed upon annuli representing diapiric emplacement of the plutons. A model of emplacement involving two magmatic pulses is given in the following sequence: Diorite pulse (i) dioritequartz diorite, (ii) tonalites; granodiorite pulse (iii) hornblende-fildspar microporphyry, hornblende/biotite porphyry, (iv) coarse grained granodiorite, (v) quartz-feldspar porphyry, (vi) feldspar porphyry, and (vii) lamprophyre. The combination of plutonic and coarse porphyritic textures, extensive propylitic overprinting of potassic alteration assemblages suggests that the. prospect represents the lower reaches of a porphyry system.

Maurice Sand, un créateur fantastique méconnu : la transversalité, brisant d’une œuvre au 19e siècle

Sauf par des regards fugitifs et distraits sur son travail d’illustrateur et son théâtre de marionnettes, l’histoire culturelle et littéraire n’a en général retenu de Maurice Sand que son état de fils bien-aimé de la plus célèbre écrivaine du 19e siècle. Étudiée pour elle-même, son œuvre multidisciplinaire - qui allie peinture, dessin, illustration, théâtre, histoire de l’art, sciences naturelles - se propose pourtant avec cohérence, marque d’une création soutenue plutôt que du dilettantisme où son souvenir s’est incrusté. Maurice Sand apparaît alors comme un de ces individus situés aux interstices des récits majeurs de la littérature et des arts qui, bien qu’ayant figure de minores, amènent à des réflexions nuancées sur la constitution de ces récits. Explorer son cas permet ainsi de scruter de plus près les mécanismes de la méconnaissance qui a pu et peut encore affecter un créateur et une œuvre soumis aux arbitrages mémoriels. Discrets angles morts de l’histoire, certains de ces mécanismes jalonnent clairement son parcours et les aléas de sa trace posthume. D’une part le vaste corpus des études sur George Sand, notamment des écrits biographiques et autobiographiques, fait voir à l’œuvre le mode déformant de la constitution de la mémoire d’un être saisi à partir des positions d’autrui : son existence devient cliché, elle se réduit peu à peu au rôle d’adjuvant dans des débats, passés ou actuels, qui font l’impasse sur le cours autonome de sa carrière, voire de sa vie. D’autre part la mise au jour de son œuvre, enfin vue comme un ensemble, dévoile une cause encore plus déterminante de sa méconnaissance. Presque tous les travaux de Maurice Sand sont traversés par une ligne de fantastique, au surplus connotée par son intérêt pour les sciences liées à la métamorphose, de l’ethnogénie à l’entomologie. Réinvention constante du passé, sa démarche cognitive et créatrice ignore les frontières disciplinaires, son objet est hybride et composé. L’œuvre se constitue ainsi par transversalité, trait et trame irrecevables en un siècle qui n’y perçut que dispersion, mais paradoxalement marque supérieure de qualité dans le champ éclaté où se déploient les arts de notre temps.

Settlement Of Reinforced Sand In Foundations

The technique of reinforcing soil for foundation improvement is well established. This paper addresses the aspect of settlement of reinforced sand foundations, where the major part of the existing work deals with the aspect of bearing capacity. A detailed analysis is made paying individual attention to soil, reinforcement, and the interface between the two. A three-dimensional, nonlinear finite-element analysis is presented that uses a three-dimensional, nonlinear soil-reinforcement interface friction element, along with other threedimensional elements to model the system. The results of the analysis are compared with those from tests conducted in the laboratory and are found to be in good agreement. The studies lead to a better understanding of the behavior of the system at different stages of loading

The objective of the present article is to illustrate the social interstice (Las Jarretaderas) existing between the municipalities Bahía de Banderas, Nayarit and Puerto Vallarta, Jalisco. The researched community is an outstanding case-study providing an in-depth analysis of a number of social process mostly related to the chiapaneca migration. The text is divided into two sections. The first one deals with the urbanization process of the metropolitan area of Puerto Vallarta. The second and longer section defines the concept of social interstice and explains how the researched locality falls under under that previously-defined concept according to the processes analyzed.
