Changes in the exploitation dynamics of small terrestrial vertebrates and fish during the Pleistocene-Holocene transition in the SW Iberian Peninsula: A review

The Pleistocene-Holocene transition c. 11.5 ka cal. BP is associated with dramatic climatic changes. These events led to fundamental shifts in landscape and have, therefore, been seen as responsible for a major impact on the human ecological behavior of the last hunter-gatherers in the Western European territory. In the case of Iberian Peninsula, it is commonly assumed that these human ecological adaptations are reflected in the new settlement and subsistence patterns that characterized the Late Upper Paleolithic-Mesolithic transition. Following the argument, the main aim of this paper is to present the state-of-the-art and consider this theoretical model using zooarchaeological data of small terrestrial vertebrates and fish from SW Portugal. Archaeological data are reviewed and discussed in order to analyze the change in the exploitation of small game, birds, and aquatic resources during this period. In this paper, we reinforce the idea that in SW Iberia, subsistence intensification and diversification precede the transition itself and are more likely to be related to other long-term phenomena, cultural and/or demographical, than to the changes in settlement behavior. The state-of-the-art discussed here led to new research questions related to the role of small vertebrates on the changes in human subsistence behavior during the Pleistocene-Holocene from Western Iberia

Acidentes de trabalho com mototaxistas Occupational accidents among mototaxi drivers

A utilização da motocicleta como meio de trabalho vem contribuindo para o aumento no número dos acidentes de trânsito e se constituindo em acidentes de trabalho para os mototaxistas. O objetivo deste estudo foi estimar a incidência anual de acidentes de trabalho entre mototaxistas cadastrados em Feira de Santana, BA. Trata-se de um estudo de caráter descritivo e censitário. Foram entrevistados 267 profissionais dos 300 cadastrados na Secretaria Municipal de Transporte e Trânsito - SMTT, através de questionário estruturado. Procedeu-se à análise descritiva e foram estimadas incidências anuais de acidentes de trabalho segundo as variáveis de interesse. Calcularam-se os riscos relativos e, como medida de significância estatística, utilizou-se o teste de qui-quadrado de Pearson e o teste exato de Fisher, adotando-se p < 0,05. Utilizou-se a regressão logística no intuito de realizar a análise simultânea das variáveis estudadas. Observou-se uma incidência anual de acidentes de trabalho de 10,5%. Ocorreram lesões leves, principalmente ferimentos (48,7%), sendo necessário afastamento das atividades laborais para 27% dos profissionais. Na análise de regressão logística verificou-se associação entre quantidade de dias de trabalho por semana, presença de fadiga em membros inferiores e queixa musculoesquelética e os acidentes de trabalho. O conhecimento acerca das condições de trabalho e dos acidentes envolvidos nessa atividade pode ser de grande importância para a adoção de políticas de educação no trânsito, com vistas à prevenção de acidentes e melhoria das condições de trabalho e de vida desses profissionais.<br>The use of motorcycles as a means of work has contributed to the increase in traffic accidents, in particular, mototaxi accidents. The aim of this study was to estimate and characterize the incidence of occupational accidents among the mototaxis registered in Feira de Santana, BA. This is a cross-sectional study with descriptive and census data. Of the 300 professionals registered at the Municipal Transportation Service, 267 professionals were interviewed through a structured questionnaire. Then, a descriptive analysis was conducted and the incidence of accidents was estimated based on the variables studied. Relative risks were calculated and statistical significance was determined using the chi-square test and Fisher's exact test, considering p < 0.05. Logistic regression was used in order to perform simultaneous adjustment of variables. Occupational accidents were observed in 10.5% of mototaxis. There were mainly minor injuries (48.7%), 27% of them requiring leaves of absence from work. There was an association between the days of work per week, fatigue in lower limbs and musculoskeletal complaints, and accidents. Knowledge of the working conditions and accidents involved in this activity can be of great importance for the adoption of traffic education policies, and to help prevent accidents by improving the working conditions and lives of these professionals
