The comparability of quantitative surveys on sport participation in France (1967-2010)

Results from quantitative surveys enable historians, sociologists and demographers to describe and analyse the evolution of sport participation in France from 1967 to 2010. However, most of these social scientists use the results of these surveys to create very different methodologies without having studied the surveys' empirical data or databases. In this article, we demonstrate how we have attempted to establish a basis for comparability of the surveys by analysing these databases. As a result of our work, certain affirmations on which the history of sport participation in France has long been based may be called into question or even changed.

Impact of a Youth Development Camp on Participants’ Skills, Attitudes, and Views Towards Science and Scientific Inquiry

This mixed-methods research study sought to determine the impact of an informal science camp—the Youth Science Inquiry Development Camp (YSIDC)—on participants’ science inquiry skills, through self-assessment, as well as their views and attitudes towards science and scientific inquiry. Pre and post data were collected using quantitative surveys (SPSI, CARS), a qualitative survey (VOSI-E), interviews, and researcher’s observations. Paired sample t-tests from the quantitative surveys revealed that the YSIDC positively impacted participants’ science inquiry skills and attitudes towards science. Interviews supported these findings and provided contextual reasons for these impacts. Implications from this research would suggest that informal and formal educational institutions can increase science inquiry skills and promote positive views and attitudes towards science and scientific inquiry by using non-competitive cooperative learning strategies with a mixture of guided and open inquiry. Suggested directions for further research include measuring science inquiry skills directly and conducting longitudinal studies to determine the lasting effects of informal and formal science programs.

Avaliação do custo de construção em função do traçado da rede coletora de esgoto sanitário

Um dos principais entraves para expansão do Sistema de Esgotamento Sanitário no país é o alto custo da implantação da rede coletora de esgoto, uma vez que está relacionada diretamente com a profundidade. Considerando este problema, o presente trabalho apresenta dois diferentes estudos de traçados de rede coletora do tipo separador absoluto para o município de Santa Cruz do Arari – Marajó – Pará, a fim de encontrar a menor profundidade e consequentemente o melhor custo. Primeiramente, foram elaborados dois traçados de rede coletora de esgoto na área com maior concentração populacional sendo dimensionado conforme as normas técnicas existentes. A partir dos levantamentos quantitativos de cada traçado, foram realizadas planilhas orçamentárias com a possibilidade de comparar entre si o menor custo de rede. Embora houvesse pequena diferença de comprimento entre os dois traçados, o item que mais pesou foi à profundidade ao longo da rede. No trecho de chegada da Estação Elevatória de Esgoto, a profundidade teve 4,90 m e 4,77m, para o Traçado Nº 1 e para o Traçado Nº 2, respectivamente. Logo, o que melhor apresentou o custo total foi o Traçado Nº 2, com valor total de R$ 913.867,54 versus R$ 1.021.818,11 do Traçado Nº 1, representado uma economia de R$ 107.950,56 para o mesmo local. De acordo com os resultados obtidos, foi possível avaliar que o estudo de traçado de rede coletora de esgoto se torna importante para qualquer local, como neste estudo de caso, onde o município apresenta grandes dificuldades de acesso para a implantação do sistema de esgotamento sanitário.

Avian communities in woodlots in the Parque das Neblinas, Bertioga, São Paulo, Brazil

Parque das Neblinas (PN) is a 2,800 ha nature reserve contiguous with an Atlantic Forest fragment known as Parque Estadual da Serra do Mar located in the municipality of Bertioga, in the state of São Paulo, Brazil. The area originally contained Eucalyptus trees grown for paper pulp production. The aims of the study were the following: (1) to characterize the diversity of the bird community in PN; (2) to compare bird species observed in PN to species found in the Atlantic Forest; and (3) to list the percentages of species endemic to the Atlantic Forest and present in PN. Quantitative surveys used the point count method. The number of avian species recorded in PN totaled 222, of which 150 (66.4%) were associated with forest environments, 66 (29.3%) with open areas, and 10 (4.3%) with aquatic environments. The quantitative survey recorded 141 species and 2,527 contacts in 120 samples for an average of 21.05 contacts per sample. The general diversity index was H´=3.82. The study identified 15 bird species that actively participated in mixed flocks and 25 species endemic to Atlantic Forest, two of which present some kind of concern relating to conservation. Areas with Eucalyptus trees and a dense understory displayed the greatest bird species diversity, as opposed to areas with less developed or non-existent understories.

Transnationality and Social Integration within Lifestyle Migration. A comparative study of two cases in Mexico and Spain

International mobility in search of amenity spaces for long-stay tourism is a growing phenomenon. U.S. citizens have practiced this lifestyle migration for decades to Latin American countries, especially to Mexico. British citizens move to Spain for similar reasons. In this paper we make a comparative analysis of these two international contexts in order to gain greater insight into the diversity and breadth of this type of migration. The study uses quantitative surveys administered at each field site. First, we analyze the phenomenon of U.S. citizens’ mobility to Mazatlán, Mexico. Second, we analize citizens from the United Kingdom residing in El Campello, Spain. In particular we compare their socio-demographic profiles, transnational practices and some patterns of social integration.

Images of pharmacy as a career: a survey among groups of year 12 students at school

To explore the images and perceptions of pharmacy with potential applicants to undergraduate pharmacy education. There is currently considerable interest in the UK in studying aspects of the pharmacy profession because of the changing pharmacy agenda and the need to understand the workforce and its motivations. Aim: To explore the images and perceptions of pharmacy with potential applicants to undergraduate pharmacy education. Design: Four interactive focus groups involving 40 volunteer year 12 students (age 17). The focus group theme plan was designed after a review of relevant literature. A novel approach was employed using photographic images of pharmacists and doctors in varied settings. Subjects and setting: The research was carried out in six schools in the West Midlands, UK. Results: The students presented a rather negative image of pharmacy as a boring occupation in a laboratory or the back of a shop. Most had little idea of what pharmacists actually do. Unlike nursing, they were unaware of positive role models in the media. The small number who did have a realistic idea of pharmacy based it on their previous work experience in pharmacy. Conclusions: The focus group technique is useful for exploring hitherto untapped perceptions of the profession. Undertaking research with year 12 students provided some useful insights into the ways in which pharmacy as a profession is perceived. Although no claims to generalisability are made here, the results were fed into the design of quantitative surveys. The somewhat negative image presented suggests that the profession has more work to do in marketing itself to young people as a potential career choice.

Food for Pollinators: Quantifying the Nectar and Pollen Resources of Urban Flower Meadows

Planted meadows are increasingly used to improve the biodiversity and aesthetic amenity value of urban areas. Although many ‘pollinator-friendly’ seed mixes are available, the floral resources these provide to flower-visiting insects, and how these change through time, are largely unknown. Such data are necessary to compare the resources provided by alternative meadow seed mixes to each other and to other flowering habitats. We used quantitative surveys of over 2 million flowers to estimate the nectar and pollen resources offered by two exemplar commercial seed mixes (one annual, one perennial) and associated weeds grown as 300m2 meadows across four UK cities, sampled at six time points between May and September 2013. Nectar sugar and pollen rewards per flower varied widely across 65 species surveyed, with native British weed species (including dandelion, Taraxacum agg.) contributing the top five nectar producers and two of the top ten pollen producers. Seed mix species yielding the highest rewards per flower included Leontodon hispidus, Centaurea cyanus and C. nigra for nectar, and Papaver rhoeas, Eschscholzia californica and Malva moschata for pollen. Perennial meadows produced up to 20x more nectar and up to 6x more pollen than annual meadows, which in turn produced far more than amenity grassland controls. Perennial meadows produced resources earlier in the year than annual meadows, but both seed mixes delivered very low resource levels early in the year and these were provided almost entirely by native weeds. Pollen volume per flower is well predicted statistically by floral morphology, and nectar sugar mass and pollen volume per unit area are correlated with flower counts, raising the possibility that resource levels can be estimated for species or habitats where they cannot be measured directly. Our approach does not incorporate resource quality information (for example, pollen protein or essential amino acid content), but can easily do so when suitable data exist. Our approach should inform the design of new seed mixes to ensure continuity in floral resource availability throughout the year, and to identify suitable species to fill resource gaps in established mixes.

Exceptional river gorge formation from unexceptional floods

An understanding of rates and mechanisms of incision and knickpoint retreat in bedrock rivers is fundamental to perceptions of landscape response to external drivers, yet only sparse field data are available. Here we present eye witness accounts and quantitative surveys of rapid, amphitheatre-headed gorge formation in unweathered granite from the overtopping of a rock-cut dam spillway by small-moderate floods (B100–1,500m3 s�1). The amount of erosion demonstrates no relationship with flood magnitude or bedload availability. Instead, structural pattern of the bedrock through faults and joints appears to be the primary control on landscape change. These discontinuities facilitate rapid erosion (4270m headward retreat; B100m incision; and B160m widening over 6 years) principally through fluvial plucking and block topple. The example demonstrates the potential for extremely rapid transient bedrock erosion even when rocks are mechanically strong and flood discharges are moderate. These observations are relevant to perceived models of gorge formation and knickpoint retreat.

The role of biological processes in affecting the dynamics and fate of microplastics in coastal marine systems

Microplastics (MP) are omnipresent contaminants in the marine environment. Ingestion of MP has been reported for a wide range of marine biota, but to what extent the uptake by organisms affects the dynamics and fate of MP in the marine system has received little attention. My thesis explored this topic by integrating laboratory tests and experiments, field quantitative surveys of MP distribution and dynamics, and the use of specialised analytical techniques such as Attenuated-Total-Reflectance- (ATR) and imaging- Fourier Transformed Infrared Spectroscopy (FTIR). I compared different methodologies to extract MP from wild invertebrate specimens, and selected the use of potassium hydroxide (KOH) as the most cost-effective approach. I used this approach to analyse the MP contamination in various invertebrate species with different ecological traits from European salt marshes. I found that 96% of the analysed specimens (330) did not contain any MP. As preliminary environmental analyses showed high levels of environmental MP contamination, I hypothesised that most MP do not accumulate into organisms but are rather fast egested. I subsequently used laboratory multi-trophic experiments and a long-term field experiment using the filter-feeding mussel Mytilus galloprovincialis and the detritus feeding polychaete Hediste diversicolor to test the aforementioned hypothesis. Overall, results showed that MP are ingested but rapidly egested by marine invertebrates, which may limit MP transfer via predator-prey interactions but at the same time enhance their transfer via detrital pathways in the sediments. These processes seem to be extremely variable over time, with potential unexplored environmental consequences. This rapid dynamics also limits the conclusions that can be derived from static observations of MP contents in marine organisms, not fully capturing the real levels of potential contaminations by marine species. This emphasises the need to consider such dynamics in future work to measure the uptake rates by organisms in natural systems.

Exploring other childhoods through quantitative secondary analyses of large scale surveys: opportunities and challenges for children's geographers

This paper considers the potential contribution of secondary quantitative analyses of large scale surveys to the investigation of 'other' childhoods. Exploring other childhoods involves investigating the experience of young people who are unequally positioned in relation to multiple, embodied, identity locations, such as (dis)ability, 'class', gender, sexuality, ethnicity and race. Despite some possible advantages of utilising extensive databases, the paper outlines a number of methodological problems with existing surveys which tend to reinforce adultist and broader hierarchical social relations. It is contended that scholars of children's geographies could overcome some of these problematic aspects of secondary data sources by endeavouring to transform the research relations of large scale surveys. Such endeavours would present new theoretical, ethical and methodological complexities, which are briefly considered.
