The compact smooth surfaces in 3 with constant positive Gauss Curvature (Ksurfaces) form a natural class. A K-surface without boundary is itself the boundary of a convex body, so it must be embedded. The surfaces of interest to us have non-empty boundary and so are not necessarily embedded. A fundamental question is this: given a collection γ = {C1 . . . ,(More)
In this paper we shall discuss hypersurfaces M of space forms of constant curvature; where curvature means one of the symmetric functions of curvature associated to the second fundamental form. The values of the constant will be chosen so that the linearized equation will be an elliptic equation onM . For example, for surfaces in 3 the two possible(More)
Sixty-one percent (138/226) of Swiss inpatient and outpatient alcohol treatment programmes responded to a postal survey designed to assess the definition and acceptance of controlled drinking (CD) as a treatment objective, the degree to which a client's severity of dependence and finality of CD as an outcome goal were associated with acceptance, and the(More)
AIM Although several relatively recent reviews have summarized the neuropsychiatric effects associated with chronic ecstasy use, there is no published comprehensive review of studies on the acute subjective effects (ASEs) of MDMA/ecstasy. DESIGN The present study reviewed the prevalence, intensity and duration of ASEs collected from 24 studies that(More)
3 is the boundary of two spherical caps of constant mean curvature H for any positive number H, which is at most the radius of C. It is natural to ask whether spherical caps are the only possible examples. Some examples of constant mean curvature immersed tori by Wente [7] indicate that there are compact genus-one immersed constant mean curvature surfaces(More)
Measures of subjective drug craving - often defined as the experience of an intense or compelling urge or desire - may be used to predict relapse, evaluate psychological and pharmacological treatments, and test theories of addiction and craving. This review summarizes both direct self-report questionnaires and indirect behavioral, physiological and reaction(More)
We recruited a sample of university student gamblers (n = 48) to complete a web-based battery of instruments in a study designed to assess the impact of imagery-based versus photographic cue exposure on acute craving to gamble using the multi-item Gambling Urge Scale (GUS; Raylu and Oei 2004). Although self-reported craving increased following both forms of(More)
OBJECTIVE The present study was conducted to provide a nationwide survey of acceptance of nonabstinence goals and related alcoholism treatment practices by Canadian alcoholism treatment services. METHOD A random sample of 335 Canadian alcoholism treatment service agencies were mailed a 4-page questionnaire designed to assess acceptance of moderate(More)
In this paper we study the conformal structure and the asymptotic behavior of properly embedded minimal surfaces of finite topology in . One consequence of our study is that when such a surface has at least two ends, then it has finite conformal type, i.e., it is conformally diffeomorphic to a compact Riemann surface punctured in a finite number of points.(More)
Although the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) does not explicitly list craving as a diagnostic criterion for pathological gambling, theories of disordered gambling and research on relapse precipitants suggest that cravings--among other factors--provoke and maintain episodes of gambling. Assessment of craving to gamble(More)
