Time-Driven Activity-Based Costing: designing a model in a Portuguese production environment

Purpose: By designing a pilot Time-Driven Activity-Based Costing (TDABC) model, this study seeks to examine in depth the suitability and the complexity of TDABC in a manufacturing company. Design/Methodology/Approach: To obtain a deeper understanding on the matters to analyse, this research adopts an interventionist approach. The host organisation is GP, a Portuguese company in the frozen food sector. Findings: Our experience allows us to assert that TDABC is suitable for a manufacturing company and it is able to deal with the variability of the industrial processes. Nonetheless, through a comparison with the models presented in the literature, TDABC appears to be more complex for manufacturing. We argue that this happens for two reasons: First, the two types of resources (human labour and machinery) used in production areas create a need to split tasks and to create two equations for each process, something that does not happen in service companies. Second, times are difficult to individualise for certain highly automated procedures, which could also give rise to some errors. Research limitations/implications: The designed model is compared to other models presented in the literature. Practical implications: This study shows a real example of TDABC in manufacturing and the procedural innovation of the time equations. Originality/Value: Since the TDABC literature has been mostly focused on examples of service companies, we examine the technical suitability and the complexity of TDABC in manufacturing companies.info:eu-repo/semantics/acceptedVersio

Influência da distância na transferência de Tabanídeos (Mutucas) entre equinos.

O presente estudo, realizado na Fazenda Nhumirim, Pantanal Sul-Mato-Grossense, objetivou avaliar a influência da distância na transferência de tabanídeos entre equinos e inferir sobre o uso potencial de barreiras espaciais na redução da transmissão mecânica de patógenos por esses vetores.bitstream/CPAP-2010/57305/1/BP92.pd

Inequalities for dealing with detector inefficiencies in Greenberger-Horne-Zeilinger-type experiments

In this article we show that the three-particle GHZ theorem can be reformulated in terms of inequalities, allowing imperfect correlations due to detector inefficiencies. We show quantitatively that taking into accout those inefficiencies, the published results of the Innsbruck experiment support the nonexistence of local hidden variables that explain the experimental result.Comment: LaTeX2e, 9 pages, 3 figures, to appear in Phys.

Approaching equilibrium and the distribution of clusters

We investigate the approach to stable and metastable equilibrium in Ising models using a cluster representation. The distribution of nucleation times is determined using the Metropolis algorithm and the corresponding $\phi^{4}$ model using Langevin dynamics. We find that the nucleation rate is suppressed at early times even after global variables such as the magnetization and energy have apparently reached their time independent values. The mean number of clusters whose size is comparable to the size of the nucleating droplet becomes time independent at about the same time that the nucleation rate reaches its constant value. We also find subtle structural differences between the nucleating droplets formed before and after apparent metastable equilibrium has been established.Comment: 22 pages, 16 figure
