As radiações provindas do solo e dos sedimentos constituem um aspecto importante da caracterização geofísica e geoquímica do ambiente. Essas radiações são emitidas por radionuclídeos que podem ser: naturais ou artificiais. Assim, como os radionuclídeos os elementos maiores e traços representam peça fundamental na caracterização química de solos e sedimentos e também estão sujeitos a alterações em suas concentrações devido à atividade antrópica, como a construção de uma represa. O reservatório de Ponte Nova, localizado no estado de São Paulo, é de importância de abastecimento e econômica às populações da região leste da Região Metropolitana de São Paulo. Neste trabalho foram determinadas as concentrações de atividade dos radionuclídeos naturais da série de decaimento do 238U, e da série do 232Th e o radionuclídeo 40K, elementos maiores e traços coletados em perfis de solo e testemunhos de sedimento na área de influência do reservatório de Ponte Nova. As concentrações de atividade dos radionuclídeos apresentaram médias de: 40K com 275,6(54) Bq kg-1, 238U com 49,00(24) Bq kg-1, 226Ra com 43,7(2) Bq kg-1, 210Pb com 91(2) Bq kg-1, 232Th com 99(1) Bq kg-1, 228Th com 84(1) Bq kg-1 e 228Ra com 74,0(7) Bq kg-1, que estão acima da média da UNSCEAR. Os elementos maiores e traços apresentaram médias de: As com 4,75(8) mg kg-1, Ba com 306(3) mg kg-1, Br com 20,7(4) mg kg-1, Ca com 136,8(5) g kg-1, Ce com 151(2) mg kg-1, Co com 7,4(2) mg kg-1, Cr com 30,0(5) mg kg-1, Cs com 2,53(2) mg kg-1, Eu com 628(6) μg kg-1, Fe com 43,7(10) g kg-1, Hf com 10,30(8) mg kg-1, K com 13,1(2) g kg-1, La com 54(1) mg kg-1, Lu com 764(7) μg kg-1, Na com 852(9) mg kg-1, Nd com 33,5(5) mg kg-1, Rb com 43,0(5) mg kg-1, Sb com 0,56(1) mg kg-1, Sc com 12,2(2) mg kg-1, Se com 646(6) μg kg-1, Sm com 6,44(6) mg kg-1, Ta com 1,49(1) mg kg-1, Tb com 650(4) μg kg-1, Th com 24,2(2) mg kg-1, U com 2,53(1) mg kg-1, Yb com 1,86(2) mg kg-1 e Zn com 56(1) mg kg-1. Os parâmetros de qualidade de solo e sedimento também são apresentados. Vários elementos apresentaram fator de enriquecimento alto como Hf, Fe e As; no entanto, apesar do fator de enriquecimento alto, os índices de geoacumulação não indicam nenhuma poluição presente. Para verificar se existia correlações entre as / Radiation coming from soil and sediment are a keystone factor in environmental geochemical and geophysical characterization. These radiation come from natural occuring radionuclides or it can be enriched or made by man. Major and minor element characterization are another imprtant piece in environmental geochemical and geophysical characterization. These elements can undergo proccesses that change their concentrations by major building projects like reservoir and dam building. Ponte Nova reservoir, in São Paulo state - Brazil, is important to the water source to São Paulo Metropolitan Region and to the agrobussiness that supplies São Paulo city. In this work, the activity concentration of 238U and 232Th decay series and 40K were determined, as well as the concentration of major and trace elements in soil profiles and sediment cores collected in the catchment area of Ponte Nova reservoir following lithological data. The following mean activity concentrations were determined: 40K with 275,6(54) Bq kg-1, 238U with 49,00(24) Bq kg-1, 226Ra with 43,7(2) Bq kg-1, 210Pb with 91(2) Bq kg-1, 232Th with 99(1) Bq kg-1, 228Th with 84(1) Bq kg-1 and 228Ra with 74,0(7) Bq kg-1, which are over the UNSCEAR\'s mean. The following major and trace elements mean values are: As with 4,75(8) mg kg-1, Ba with 306(3) mg kg-1, Br with 20,7(4) mg kg-1, Ca with 136,8(5) g kg-1, Ce with 151(2) mg kg-1, Co with 7,4(2) mg kg-1, Cr with 30,0(5) mg kg-1, Cs with 2,53(2) mg kg-1, Eu with 628(6) μg kg-1, Fe with 43,7(10) g kg-1, Hf with 10,30(8) mg kg-1, K with 13,1(2) g kg-1, La with 54(1) mg kg-1, Lu with 764(7) μg kg-1, Na with 852(9) mg kg-1, Nd with 33,5(5) mg kg-1, Rb with 43,0(5) mg kg-1, Sb with 0,56(1) mg kg-1, Sc with 12,2(2) mg kg-1, Se with 646(6) μg kg-1, Sm with 6,44(6) mg kg-1, Ta with 1,49(1) mg kg-1, Tb with 650(4) μg kg-1, Th with 24,2(2) mg kg-1, U with 2,53(1) mg kg-1, Yb with 1,86(2) mg kg-1 and Zn with 56(1) mg kg-1. Soil quality parameters were calculated. Several elements had their enrichment factors high like Hf, Fe and As; however, geoaccumulation indexes did not show pollution associated with that enrichment. Correlation matrix, cluster analysis and principal component analysis were also performed.

This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material. The result also indicate that a wide range of agegroups are represented in the human bonematerial, ranging between; Infans 2 (5-14 years), Adultus (18-44 years) and Adultus/Maturus (18-64 years). The osteological analysis also show a presence of horse, pig, sheep/goat, dog and rabbit in the cairn. Due to high fragmentation and erosion no gender assessment based on the human bonematerial was made. Grave findings connected to the cairn include among other things a razor in bronze,  a pin in bronze with a spiralshaped head, a tweezer- and a miniaturesword in bronze, ceramics, coal and flint. Some of the bronze findings indicate that one of the buried individuals in the grave is of male gender. The possible meaning and role of the grave-goods in connection to the cairn and the buried individuals is discussed further in the paper. The continuity of the cairn and its roll and meaning in the society is also discussed in this thesis.

Habitat selection by breeding black ducks (Anas rubripes) was studied in Antigonish County, Nova Scotia during April-September 1990 and 1991. / Black duck pairs selected deciduous shrub ponds and sparsely vegetated ponds and avoided estuarine marsh and large lake habitat. Hens with broods preferred the deciduous shrub habitat while they avoided large lakes. / Black duck pairs appeared to use the distance to a brood-rearing pond as a cue in site selection. The closer a pond was to a suitable rearing pond the more likely it was occupied by a pair, regardless of food or cover resource availability. Black ducks, however, likely used site attributes such as the perimeter of the pond, the availability of aquatic invertebrates and the relative abundance of alder, willow and dead timber as cues in the selection brood-rearing habitat. / Black duck duckling survival, an estimate of recruitment, was the highest on preferred deciduous shrub ponds. Duckling survival was also higher on ponds with only one brood as opposed to ponds with several broods. / The most productive habitat for black ducks in the Antigonish study area were isolated, deciduous shrub ponds influenced by beaver activity. Black duck population numbers can be enhanced by managing local beaver populations.

In this qualitative research study, First Nation students in high school participated in an interview study designed to (1) describe how their school experiences related to academic success and (2) to identify learning strategies used to achieve success. Participants described the importance of achieving academic success to ensure future economic security. In their approaches to learning, participants preferred multiple modes of learning. Various types of learning strategies included both visual and verbal methods such as teacher demonstrations, reading, and writing. Motivational influences were also identified as contributing to their educational success which came from a variety of sources such as teachers, parents, peers, and community leaders. Educational success for these Aboriginal students is both multi-dimension and multi-modal. Implication of the research and future direction will be discussed.

Trata-se do município de Nova Trento, Santa Catarina, que apresenta uma configuração bilíngüe complexa, onde o comportamento linguístico em relação à língua ou ao dialeto varia nas diversas comunidades. A 1a e a 2a partes apresentam algumas considerações históricas sobre a imigração trentina no sul do país, acompanhadas por um "mapeamento" étnico-lingüístico de Nova Trento, que demonstra em quais fases de aculturação dialetal se encontra cada uma das suas vinte e quatro localidades. Na parte seguinte, através da análise das redes de comunicação, procuramos identificar quais os fatores responsáveis pela manutenção ou desaparecimento do dialeto italiano em duas áreas distintas: a rural de maior grau de bilingüismo em confronto com a urbana. A esta etapa, segue um estudo propriamente linguístico, que verifica a fluência dialetal em cada grupo de informantes. Por fim, foram feitas algumas considerações sobre os "problemas" que uma situação de bilíngüe comporta, especialmente aqueles de caráter psico-pedagógico.
