The XENON1T Dark Matter Experiment
2017
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented. © 2017, The Author(s).
Testing a methodology to improve organizational learning about crisis communication
2011
Purpose – The purpose of this paper is to introduce a measurement system with performance indicators to improve organizational learning about crisis communication by public organizations. The tool can be used to conduct a preparedness audit or to evaluate communication performance in a real situation or in an emergency exercise. Evaluation is part of the strategic planning and development of crisis communication. The construction of the instrument and its theoretical underpinnings are first explained, after which the series of empirical tests that were implemented to scrutinize the clarity and appropriateness of the indicators as well as the usability of the instrument are presented. Design…
The role of personal and relative job performance in promotion decisions
2021
This study employs personnel data from a large university to examine how supervisors utilize information on employees' job performance in promotion decisions. The study shows that better-performing employees are rewarded with promotions as a higher output of peer-reviewed publications and better quality of research output are associated with a higher probability of being promoted. The study also shows that supervisors compare their subordinates' job performance when deciding on promotions: employees who outperform their colleagues in terms of research output and research quality are more likely to be promoted. Subsequently, the study provides evidence to support the key premise of the tourn…
Vain yksi voimaharjoitus viikossa riittää toimintakyvyn ylläpitämiseen ikääntyneillä
2018
Tutkimuksella selvitimme, parantaako voimaharjoittelu iäkkäiden toimintakykyä, ja onko harjoitusmäärillä vaikutusta toimintakyvyn muutoksiin. Tutkimukseen osallistui 106 koehenkilöä (65–75 v.), jotka satunnaistettiin neljään ryhmään: 1x/vko (H1, n=26), 2x/vko (H2, n=27) ja 3x/vko (H3, n=28) harjoitteleviin ja kontrolliryhmään (K, n=25). Ensimmäisen kolmen kuukauden ajan kaikki harjoitteluryhmät voimaharjoittelivat valvotusti kahdesti viikossa (H, n=81), jonka jälkeen ryhmät harjoittelivat kuusi kuukautta (3 kk–9 kk) nimensä mukaisesti kerran, kahdesti tai kolmesti viikossa. Koehenkilöille suoritettiin testit 0 kk, 3 kk ja 9 kk. Toimintakykyä testattiin etuperinkävelyllä (E), takaperinkävely…
Collective action in implementation of a “greener” performance management system.
2010
Purpose – The purpose of this paper is to investigate how different actors influenced the implementation of an environmental management system (EMS) and a performance measurement system (PMS) in a case company when the systems are eventually integrated. Another purpose is to illustrate how the frameworks of Gibson and Earley and Lovaglia et al. can be utilized to investigate the implementation of different management systems in practice. Design/methodology/approach – This paper is an interpretative case study, which utilizes qualitative methods such as semi‐structured interviews and internal documents. Findings – The results indicate the importance of maintaining a separation between the po…
The use of digital analytics for measuring and optimizing digital marketing performance
2016
Demonstrating the monetary outcomes of marketing is no longer considered a virtue but a necessity by the top management. Marketers are increasingly held accountable for their actions, yet most marketers struggle in their attempts to measure marketing performance. The emergence of digital analytics tools (e.g., Web analytics) has raised optimism of improved measurability due to its ability to track customer behavior in the digital environment. However, research lacks a clear understanding of the opportunities and limitations of digital analytics, and what it takes from an organization to make the most of its usage. The dissertation advances the knowledge in this area by investigating how ind…
L'économie de l'éducation permet-elle de légitimer l'obligation de résultats ?
2005
International audience; Les économistes ont au moins deux bonnes raisons de s'intéresser à un mouvement en faveur de l'obligation de résultats : l'ampleur des ressources consacrées à l'éducation, et la méthode dont ils disposent pour aborder la question de l'arbitrage dans l'utilisation de ces ressources. Après avoir explicité ces raisons, nous montrerons comment l'analyse économique peut aider à guider la production, l'interprétation et l'usage d'indicateurs de résultats, au niveau macro-économique puis à celui de l'unité éducative.
Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period
2016
This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…
