Elastic Cross-Section and Luminosity Measurement in ATLAS at LHC

Recently the ATLAS experiment was complemented with a set of ultra-small-angle detectors located in ``Roman Pot'' inserts at 240m on either side of the interaction point, aiming at the absolute determination of the LHC luminosity by measuring the elastic scattering rate at the Coulomb Nuclear Interference region. Details of the proposed measurement the detector construction and the expected performance as well as the challenges involved are discussed here.Comment: EDS05, Blois, France, May 15-20, 200

The effects of human resource practices on firm growth

Although the connection between firm growth and labour is well documented in economics literature, only recently the link between human resources (HR) and firm growth has attracted the interest of researchers. This study aims to assess the extent, if any, to which, specific HR practices may contribute to firm growth. We review a rich literature on the links between firm performance and the following HR practices: (1) job security (2) selective hiring, (3) self-managed teams (4) compensation policy, (5) extensive training, and (6) information sharing. We surveyed HR managers and recorded their perceptions about the links between HR practices and firm growth. Results demonstrated that compensation policy was the strongest predictor of sales growth. Results provide overall support for all HR practices except of job security. Eventually, selecting, training, and rewarding employees as well as giving them the power to decide for the benefit of their firm, contribute significantly to firm growth

Agrifood logistics and food traceability

Traceability systems are recordkeeping systems designed to track the flow of product and/or product attributes through the production process and throughout the supply chain from producers to consumers. The aim of this study is to review the current status of traceability systems in food companies, compare different traceablity systems applied by food companies, and analyse the sources of variation in their efficiency. A traceability system is characterized by its breadth, depth, and precision. Differences in efficiency are attributed to the costs and benefits of traceability’s implementation to these three traceabiligy characteristics. Three case studies were conducted during the period April-May 2005. All cases were large food companies, with more than 250 employees, and operating for more than 20 years in Greece. All companies had a traceability system in operation. All companies had implemented a traceability system not because legislation required, but because they found it was a valuable business tool. In the operation level, the main problem was whether or not suppliers could provide traceability information in a useful format. All companies reported the same benefits from the traceability system: Better control of supply chain as well as better quality assurance –higher levels of food quality & safety
