Internet Gambling: An Overview of Psychosocial Impacts
Technological innovation has always played a role in the development of gambling behaviour, primarily through providing new market opportunities. Early prevalence studies of Internet gambling in the UK, Canada and the US have shown that Internet gambling is not a cause for concern at present However, this seems likely to change as more people start to use the Internet for leisure activities. After a brief overview of gambling technologies and deregulation issues, this paper examines the impact of technology on gambling by highlighting salient factors in the rise of Internet gambling (i.e., accessibility, affordability, anonymity, convenience, escape immersion/dissociation, disinhibition, event frequency, asociability, interactivity, and simulation). The paper also overviews some of the main social impacts surrounding Internet gambling, such as protection of the vulnerable, Internet gambling in the workplace, electronic cash, and unscrupulous operators. Recommendations for Internet gambling operators are also provided
Angular reduction in multiparticle matrix elements
A general method for the reduction of coupled spherical harmonic products is
presented. When the total angular coupling is zero, the reduction leads to an
explicitly real expression in the scalar products within the unit vector
arguments of the spherical harmonics. For non-scalar couplings, the reduction
gives Cartesian tensor forms for the spherical harmonic products, with tensors
built from the physical vectors in the original expression. The reduction for
arbitrary couplings is given in closed form, making it amenable to symbolic
manipulation on a computer. The final expressions do not depend on a special
choice of coordinate axes, nor do they contain azimuthal quantum number
summations, nor do they have complex tensor terms for couplings to a scalar.
Consequently, they are easily interpretable from the properties of the physical
vectors they contain.Comment: This version contains added comments and typographical corrections to

Fathers, Families, and the Future: A Plethora of Plausible Predictions
This commentary focuses on new directions in the study of fathers and families. Several topics that are ripe for more theoretical and empirical scrutiny are outlined. These include the biological determinants of fathering, cultural constraints on fathers, the impact of becoming a father on men’s development as adults, and an intergenerational perspective on fathering. The implications of the recent advances in our understanding of gay and lesbian parents for the critical nature of the father’s role in the family are examined. Finally, a wider range of methodological approaches—including qualitative as well as quantitative, experimental as well as correlational—is advocated in order to advance our appreciation of fathers in children’s lives
Negative experiences of non-drinking college students in Great Britain: an interpretative phenomenological analysis
Research relating to alcohol use amongst university students primarily examines the effects of binge drinking. Researchers rarely focus on a range of drinking styles including light or non-drinking. This study was designed to gain an in-depth understanding of the lived experiences of female, first year UK undergraduates, who do not drink alcohol. Semi-structured interviews were conducted with eight participants. Narratives were analysed using interpretative phenomenological analysis (IPA; by Smith and Osborn (Sage 51-80, 2003). Three superordinate themes were identified: managing the feeling that you don’t belong^ highlights the importance of managing social interactions as a non-drinker; experiencing social exclusion recognises the impact on social bonding as a result of insufficient socialising
opportunities; and experiencing peer pressure and social stigma highlights the scrutiny and labelling participants endured. These findings provide an understanding of some of the difficulties experienced by these undergraduates as a result of their non-drinking status. Implications of this research are discussed and areas for future research are outlined

Using Spin Correlations to Distinguish Zh from ZA at the International Linear Collider
We investigate how to exploit the spin information imparted to the Z boson in
associated Higgs production at a future linear collider as an aid in
distinguishing between CP-even and CP-odd Higgs bosons. We apply a generalized
spin-basis analysis which allowsus to study the possibilities offered by
non-traditional choices of spin projection axis. In particular, we find that
the Z bosons produced in association with a CP-even Higgs via polarized
collisions are in a single transverse spin-state (>90% purity) when we use the
Zh-transverse basis, provided that the Z~bosons are not ultra-relativistic
(speed <0.9c). This same basis applied to the associated production of a CP-odd
Higgs yields Z's that are an approximately equal mixture of longitudinal and
transverse polarizations. We present a decay angular distribution which could
be used to distinguish between the CP-even and CP-odd cases. Finally, we make a
few brief remarks about how this distribution would be affected if the Higgs
boson turns out to not be a CP-eigenstate.Comment: 48 pages, 18 figures, revtex
