Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
Understanding Crowdturfing : The Different Ethical Logics Behind the Clandestine Industry of Deception
2017
Crowdturfing, the dark side and usually unnoticed face of crowdsourcing, represents a form of cyber-deception in which workers are paid to express a false digital impression. While such behavior may not be punishable under the jurisdiction of formal law, its consequences are destructive to the cohesion and trustworthiness of online information. The conceptual work at hand examines the current literature on the topic, and lays the foundation for a theoretical framework that explains crowdturfing behavior. We discuss crowdturfing through three ethical normative approaches: traditional philosophical ethics, business ethics, and codified rules. We apply these lenses to an illustrative example o…
Game of Thrones -pelin Let's Play -videot ja populaarikulttuurin vastaanotto esityksenä
2019
Suositun Valtaistuinpeli (Game of Thrones) -tv-sarjan myötä George R. R. Martinin Tulen ja jään laulu -kirjasarjaan perustuvasta transmediauniversumista on tullut ilmiö, jolla on faneja huomattavasti laajemmin kuin vain fantasiaharrastajien piirissä. Tässä artikkelissa pyrin selvittämään tapoja, joilla ihmiset kokevat Valtaistuinpelin maailman, hahmot ja tapahtumat, ja sitä, miten he niitä tulkitsevat ja suhteuttavat omaan elämänkokemukseensa. Hypoteesina on, että Let’s Play -videot tarjoavat hedelmällisen aineiston pelien ja yleisemmin populaarikulttuurin synnyttämien kokemusten tarkasteluun.Tutkimusmenetelmänäni on Game of Thrones -videopelistä tehtyjen Let’s Play -videoiden analysointi e…
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…
Digital Mental Health Resources for Children and Youth : Evaluation of Strengths in User Interface Design
2019
The aim of this research is to explore the positive user interface (UI) design of digital mental health resources for children and youth. For this purpose, a heuristic model is introduced and heuristic evaluation is used as a method to systematically assess 49 digital mental health resources. In the assessment, the resources are evaluated by observing the prevalence of UI design strengths defined in the heuristic model. The results of the study indicate that the resources analyzed have strengths especially in the dimensions of visual design, content, reliability, engagement and functional design. Furthermore, all of the resources have at least four design strengths, creating a good basis fo…
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…
Measuring Performance in the Luxury Industry: Is there a Difference in Performance Between the top and Bottom Players in the Industry?
2021
Abstract This paper presents a methodology that consists of a Z-score function applied on a set of indicators for the luxury industry and then standardized to obtain a ranking of the companies on a scale between 10 and 100. To measure the performance for the top 5 LVMH, Estee Lauder, Richemont, Kering, Essilor Luxottica, and bottom 5 Aeffe, Tribhovandas, Van de Velde, Mulberry, Trinity companies (based on Deloitte global ranking in 2019) in the luxury industry and to unveil which are the performance drivers. By applying this methodology it can be made a comparison in performance between the top and the bottom companies in the luxury industry. The performance score is calculated for ten year…
