Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications
that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD.
This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults
(n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which
persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent
ADHD. 相似文献

Despite the substantial amount of literature focusing on social support for pregnant and parenting adolescents, few studies
have directly examined the relationships among stress and social support across their transition to parenting. The present
study investigates the nature of the relationship between stress and support both before and after the birth of the baby.
Two groups of adolescent females (one group facing parenthood and one not) completed measures of support and stress across
a 7-month period (N = 231) to coincide with the transition to parenthood. In general, support and stress were negatively related when measured
concurrently and positively related over time for parenting adolescents but not the non-parenting group. Understanding how
long social support impacts stress will enable practitioners to identify when best to provide interventions for pregnant and
parenting adolescents. 相似文献

Legalized gambling in Canada is governed by Provincial legislation. In Ontario, the Ontario Lottery and Gaming Corporation
is responsible for all aspects of gambling in the Province. There have been a number of recent lawsuits against this Crown
agency of the Government of Ontario by gamblers, most of which have been settled or otherwise resolved. A recent class-action
lawsuit on behalf of thousands of Ontario gamblers against this agency raises a number of interesting questions regarding
the issue of responsibility and liability. The questions surround the issue of self-exclusionary practices of gamblers who
deem themselves in need of external intervention in order interesting questions regarding the issue of responsibility and
liability. The questions surround the issue to abstain from further gambling. A contract is voluntarily signed by the self-excluding
gamblers whereby their further attendance at gaming venues is prevented and could be punishable by law. Where the gaming venues
have failed to enforce the terms of this contract, gamblers have continued to gamble at these establishments. The class-action
lawsuit stems from the grievances of these self-excluded gamblers who were not turned away. Relevant psychological theories
and recent findings pertaining to gambling are reviewed and questions relevant to these grievances are discussed in favor
of government responsibility and liability toward gamblers. 相似文献

Using data from the 2004 and 2005 Consumer Expenditure Surveys (CES) comprising of 15,000 respondents, this study examines
two research questions. The first of these considers the demographic differences between households whose members lose money
playing the lottery and/or engaging in pari-mutuel betting and those whose members do not lose money participating in such
activities. The second assesses demographic differences among households whose members lose money playing the lottery and/or
engaging in pari-mutuel betting. It was found that respondents living in money-losing households are slightly older, better
off financially, more likely to be married or divorced, more likely to live in a state with at least one legal casino and
more likely to live in the Northeast than respondents living in non-money-losing households. Among those living in money-losing
households, the least wealthy and African American respondents are more likely to lose a higher proportion of their respective
incomes purchasing lottery tickets and engaging in pari-mutuel betting than wealthier respondents and whites. 相似文献

In this paper, we introduce a combinatorial problem faced in the tire industry and then define it and optimize it by tabu
search from the perspective of operational research. Such a problem is termed the pitch arrangement problem and involves both
selecting and sequencing problems along with noninteger design variables. Pitch arrangement is an essential procedure for
tires before their manufacture. Using this procedure, engineers have to choose an optimal groove distribution on tire treads
for the purpose of manufacturing low-noise tires. Most research works on pitch arrangement are supported by tire companies,
and their results are patented instead of being published. In this study, we define the abovementioned problem clearly and
optimize it by tabu search. Two actual manufactured tires are chosen for the case studies. In addition, two patents and two
types of pitch sequences optimized by genetic algorithms are also applied to these two tires for comparison. The pitch arrangement
is optimized successfully and the performance of tabu search is found to be outstanding. 相似文献
