Seniors and gambling : pleasure or addiction. A French example

2016

International audience; The gambling industry has grown steadily in France, in particular since the new regulation of the online gambling in 2010. Seniors are commonly regarded as a high-risk population. Gaming indeed constitutes one of the most frequent leisure-time activities for seniors, who are an attractive target group for the gaming operators. If they have been much less described and analyzed than those of the younger generations, the seniors' playful practices can be as problematical. A sociological study was carried out in the Burgundy and Franche-Comte region to investigate the seniors' behaviors towards gambling and games of chance, through their representations, misbeliefs and …

Music in Gambling Contexts : What are Individuals' Perceptions of Music Experienced in Gambring Contexts & Why Do Individuals Self-Select Music to Ac…

2013

Music influences behaviours in everyday contexts (North & Hargreaves, 2008) and is a factor which can influence gambling behaviour (Griffiths & Parke, 2005; 2003). Experimenter-selected background music has been found to influence indices of gambling behaviour in laboratory gambling experiments (e.g. Spenwyn, Barrett & Griffiths, 2010; Noseworthy & Finlay, 2009; Dixon, Trigg & Griffiths, 2007; Marmurek et al., 2007). However, less is known about gamblers’ experience of music in real-life gambling contexts. To date research has considered music’s utilisation in gambling environments where fruit machines are located (Griffiths & Parke, 2005). Therefore further research is required to determin…

The Grinders : Making Meaning in the Online and Offline Lives of Internet Poker Players

2015

Problem gambling affects only 1–3 percent of the gambling population but still most research on gambling is problem-oriented (Raento 2011, 76). Thus, the negative “cover story” (Gubrium 2008, 512) of gambling needs to be unsettled and complemented, because it obscures the complexities of the lived reality of mainstream gambling culture (Reith & Dobbie 2011; Matilainen & Raento 2014, 433; Jouhki 2011a, 79). Most gamblers are not the marginalized, addicted persons so often envisioned in both research and the media (Vuorento 2011; Binde 2007, 152–157): the mainstream of gambling is about entertainment, excitement, mental challenge and social value. To some it is also a profession. This article…

Psychosocial Perspective on Problem Gambling : The role of Social Relationships, Resilience, and COVID-19 Worry

2023

AbstractThe COVID-19 pandemic has amplified several psychosocial risks and problem behaviors among vulnerable individuals. Given that gambling has high addictive potential, it is important to consider the underlying mechanisms of problem gambling. This study examined psychosocial factors associated with pandemic-time problem gambling.Cross-sectional data were gathered via an online survey of 18–75-year-old Finnish, Swedish, and British respondents (n = 2,022) who reported having gambled at least occasionally during the pandemic. Measures included problem gambling, loneliness, COVID-19 worry, social support, and psychological resilience. Control variables included gender, age, and education.…

Gelation and gel properties of two- and three-component pyrene based low molecular weight organogelators

2011

The research described in this thesis covers the synthesis, characterization and the study of the gelation ability of fteen pyrene based low molecular weight organogelators (LMOGs). The gelation and gel properties were investigated by rheometry, scanning electron microscopy, di erential scanning calorimetry, UV-Vis and uorescence spectroscopy. The pyrene based LMOGs form complexes with 2,4,7-trinitro uorenone (TNF) and self-assemble non-covalently through - stacking, donor-acceptor and van der Waals interactions to form thermoreversible gels, which remain stable at least for two years. The strongest gels were obtained in primary alcohols whereas the poor solubility of TNF restricted gelatio…

Multivalent N-donor ligands for the construction of coordination polymers and coordination polymer gels

2018

This work describes the synthesis and characterisation of several multivalent N-donor ligands and their coordination compounds and the use of these ligands in the construction of coordination polymers and coordination polymer gels. The project can be divided into two parts. The first part of the research is focused on the coordination chemistry of ring-substituted biimidazoles in acidic media. The dependence of the formation of ion pairs and zwitterionic, especially zinc and copper containing coordination compounds on the pH of the reaction medium and ring-substituents of the ligand were examined. The second part of the study deals with the preparation of Ag, Zn and Cu coordination polymers…

Nanoscale probing of the supramolecular assembly in a two‐component gel by near‐field infrared spectroscopy

2023

The design of soft biomaterials requires a deep understanding of molecular self-assembly. We introduce here a nanoscale infrared (IR) spectroscopy study of a two-component supramolecular gel to assess the system´s heterogeneity and supramolecular assembly. In contrast to far-field IR spectroscopy, near-field IR spectroscopy revealed differences in the secondary structures of the gelator molecules and non-covalent interactions at three distinct nano-locations of the gel network. A β-sheet arrangement is dominant in single and parallel fibres with a small proportion of an α-helix present, while the molecular assembly derives from strong hydrogen bonding. However, at the crossing point of two …

Arsenite-induced aneuploidy following short and long-term exposure in mammalian cells

2009

We studied the long-term progression of chromosomal instability in V79 cells treated acutely with arsenite (10mM, 24 hr) followed by growth in arsenic-free medium for 120 cell generations. Indirect immunostaining using anti-ß-tubulin antibody showed severe alterations in spindle morphology after only 6 h treatment and cytogenetic investigations carried out at the end of treatment revealed that the percentage of cells with 21 chromosomes (modal number of the cell line) decreased, making way for aneuploid cells. The acquired instability remained and propagated within the cell population. Moreover, we treated V79-derived G12 cells with sub-lethal doses (0.1-1.0 μM) of arsenite for 10 days foll…
