As experiências em proteção florestal da divisão florestal da Rigesa Meadwestvaco.

As experiências em proteção florestal da divisão florestal da Rigesa MeadWestvaco. A Divisão Florestal da Rigesa foi instalada em Três Barras SC em 1955 e atualmente possui unidades de manejo em 17 municípios no norte de Santa Catarina e sul do Paraná. A atividade florestal está voltada para o plantio, manejo e colheita de madeira plantada de Pinus e Eucalyptus. Na área de Proteção Florestal ao longo dos anos surgiram diversos desafios, para os quais a empresa tem criado ações específicas desenvolvidas por seu corpo técnico através de projetos cooperativos com Universidades e Instituições de Pesquisa, com o objetivo de encontrar a melhor solução para cada situação. Neste trabalho estão relatadas as últimas experiências e soluções encontradas pela empresa para os seguintes assuntos; Manejo Integrado do Pulgão-do- Pinus Cinara spp, detecção de Pissodes castaneus em florestas de Pinus; Cálculo da FMA ? Fórmula de Monte Alegre através da Estação Meteorológica Automática1 CD-ROM. Palestra (Pragas florestais). Co-promoção: Embrapa Florestas

Re-embedding agency at the workplace scale: workers and labour control in Glasgow call centres

Following recent calls for the development of a more embedded sense of labour agency, this paper focuses on the scale of the workplace which is largely absent from recent labour geography debates. Drawing on studies in the labour process tradition, the paper presents empirical research on call centre work in Glasgow, utilising this to revisit the concept of local Labour Control Regimes (LCR). We argue that rather than being simply imposed by capital and the state ‘from above’, workplace control should be seen as the product of a dialectical process of interaction and negotiation between management and labour. Labour’s indeterminacy can influence capital in case specific ways as firms adapt to labour agency and selectively tolerate and collude with certain practices and behaviours. Workers’ learned behaviour and identities are shown to affect not only recruitment patterns in unexpected ways, but also modes of accepted conduct in call centres. Accordingly, the case is made for the influence of subtle – yet pervasive – worker agency expressed at the micro-scale of the labour process itself. This, it is argued, exerts a degree of ‘bottom-up’ pressure on key fractions of capital within the local LCR

DARDIS: Distributed and randomized dispatching and scheduling

Scheduling and dispatching are critical enabling technologies in supercomputing and grid computing. In these contexts, scalability is an issue: we have to allocate and schedule up to tens of thousands of tasks on tens of thousands of resources. This problem scale is out of reach for complete and centralized scheduling approaches. We propose a distributed allocation and scheduling paradigm called DARDIS that is lightweight, scalable and fully customizable in many domains. In DARDIS each task offloads to the available resources the computation of a probability index associated with each possible start time for the given task on the specific resource. The task then selects the proper resource and start time on the basis of the above probability. The scheduler can be customized with different policies to fit several objective functions like load balancing or makespan. We evaluate our approach in the domain of grids and supercomputers. We compare DARDIS with the most widely used algorithms used in these specific domains to show that this approach can reach better solutions in several cases
