Handling of the generation of primary events in Gauss, the LHCb simulation framework

Abstract: The LHCb simulation application. Gauss, consists or two independent phases, the generation of the primary event and the tracking of particles produced in the experimental setup. For the LHCh experimental program it is particularly important to model IS meson decays: the KvtGcn code developed in CLEO and BaBah has been chosen and customized for non-coherent B production as necuring in pp collisions at the LHC, The initial proton-proto n collision is provided by a different generator engine, currently PYTHIA 6 for massive prwluclion of signal and generic pp collisions events. Beam gas events, background events originating from proton halo, cosmics and calibration events for different detectors can be generated in addition to pp collisions. Different generator packages as available in the physics community or specifically developed in LHCb are used for the different purposes. Running conditions affecting the events generated such as the size of the luminous region, the number of collisions occuring in a bunch crossing and the number of spill-over events from neighbouring bunches are modeled via dedicated algorithms appropriately configured. The design of the generator phase of Gauss will be described: a modular structure with well defined interfaces specific to the various tasks, e.g. pp collisions, particles' decays, selections, etc. has been chosen. Different implementations are available for the various tasks allowing selecting and combining them as most appropriate at run time as in the case of Pythia 6 im pp collisions or HIJING for beam gas. The advantages of such structure, allowing for example to adopt transparently new generators packages will be discussed.

Prosocial Spending and Well-Being: Cross-Cultural Evidence for a Psychological Universal

Abstract: This research provides the first support for a possible psychological universal: human beings around the world derive emotional benefits from using their financial resources to help others (prosocial spending). Analyzing survey data from 136 countries, we show that prosocial spending is consistently associated with greater happiness. To test for causality, we conduct experiments within two very different countries (Canada and Uganda) and show that spending money on others has a consistent, causal impact on happiness. In contrast to traditional economic thought--which places self-interest as the guiding principle of human motivation--our findings suggest that the reward experienced from helping others may be deeply ingrained in human nature, emerging in diverse cultural and economic contexts.

Pulsatile Stimulation Determines Timing and Specificity of NF-κB-Dependent Transcription

Abstract: The nuclear factor kappa B (NF-kappa B) transcription factor regulates cellular stress responses and the immune response to infection. NF-kappa B activation results in oscillations in nuclear NF-kappa B abundance. To define the function of these oscillations, we treated cells with repeated short pulses of tumor necrosis factor-alpha at various intervals to mimic pulsatile inflammatory signals. At all pulse intervals that were analyzed, we observed synchronous cycles of NF-kappa B nuclear translocation. Lower frequency stimulations gave repeated full-amplitude translocations, whereas higher frequency pulses gave reduced translocation, indicating a failure to reset. Deterministic and stochastic mathematical models predicted how negative feedback loops regulate both the resetting of the system and cellular heterogeneity. Altering the stimulation intervals gave different patterns of NF-kappa B-dependent gene expression, which supports the idea that oscillation frequency has a functional role.

The structure and evolution of the strategic management field: A content analysis of 26 years of strategic management research

Abstract: This paper analyses 26 years of strategic management research published in Academy of Management Journal, Academy of Management Review, Administrative Science Quarterly and Strategic Management Journal. Through a content analysis, it studies the relationships between the subfields of strategic management. A multiple correspondence analysis provides a map of keywords and authors, and a framework to track this literature over the 26-year period. A discussion of future pathways in the strategic management literature is also provided.

Happiness and Productivity

Abstract: Some firms say they care about the well-being and “happiness” of their employees. But are such claims hype or scientific good sense? We provide evidence, for a classic piece rate setting, that happ...
