Conceptual framework of harmful gambling: An international collaboration, Third Edition
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Although it is seen by many as a form of leisure and recreation, gambling can have serious repercussions for individuals, families, and society as a whole. The harmful effects of gambling have been studied for decades in an attempt to understand individual differences in gambling engagement and the life-course of gambling-related problems. In this publication, we present a comprehensive, internationally relevant conceptual framework of “harmful gambling” that moves beyond a symptoms-based view of harm and addresses a broad set of factors related to population risk, community, and societal effects. Factors included in the framework represent major topics relating to gambling that range from specific (gambling environment, exposure, types, and resources) to general (cultural, social, psychological, and biological). The framework has been created by international, interdisciplinary experts in order to facilitate an understanding of harmful gambling. It reflects the state of knowledge related to factors influencing harmful gambling, and serves a secondary purpose as a guide for the development of future research programs and to educate policy makers on issues related to harmful gambling. Gambling Research Exchange Ontario (GREO) (formerly the Ontario Problem Gambling Research Centre (OPGRC) located in Guelph, Ontario, Canada) has facilitated the development of the Conceptual Framework of Harmful Gambling and retains responsibility for keeping it up-to-date.

Lateral spårstabilitet -- slutrapport
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Det gemensamma CHARMEC/SP-projektet Lateral spårstabilitet startade 2003 och avslutades under våren 2007. Det övergripande målet för projektet var att motverka uppkomsten av solkurvor. Detta skulle åstadkommas genom att öka möjligheten att besvara de två fundamentala frågorna när det gäller uppkomsten av solkurvor: Vilken kompressiv axialkraft verkar i rälen och vilket sidomotstånd har spåret? Detta övergripande mål bröts ned i tre delprojekt: · Utveckling av bättre metoder för mätning av spänningsfri temperatur · Numerisk simulering av ballastens sidomotstånd · Utveckling av en numerisk modell för prediktering av uppkomst av solkur- vor. Detta är en kortfattad sammanställning av vad som utförts och vilka resul- tat som uppnåtts. Detaljerad information finns i de hänvisade rapporterna.

Light Dark Matter eXperiment (LDMX)
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We present an initial design study for LDMX, the Light Dark Matter Experiment, a small-scale accelerator experiment having broad sensitivity to both direct dark matter and mediator particle production in the sub-GeV mass region. LDMX employs missing momentum and energy techniques in multi-GeV electro-nuclear fixed-target collisions to explore couplings to electrons in uncharted regions that extend down to and below levels that are motivated by direct thermal freeze-out mechanisms. LDMX would also be sensitive to a wide range of visibly and invisibly decaying dark sector particles, thereby addressing many of the science drivers highlighted in the 2017 US Cosmic Visions New Ideas in Dark Matter Community Report. LDMX would achieve the required sensitivity by leveraging existing and developing detector technologies from the CMS, HPS and Mu2e experiments. In this paper, we present our initial design concept, detailed GEANT-based studies of detector performance, signal and background processes, and a preliminary analysis approach. We demonstrate how a first phase of LDMX could expand sensitivity to a variety of light dark matter, mediator, and millicharge particles by several orders of magnitude in coupling over the broad sub-GeV mass range.
