These findings add to a growing body of literature suggesting merit in investigating positive psychological factors together with negative factors when assessing suicide risk and planning psychological services for older adults.

Objective: Research has demonstrated that impulsivity is strongly associated with suicide-related ideation and behaviour among young adults. However, to date, the potential importance of impulsivity as a predictor of suicide-related ideation in later life has yet to be determined. Our study examined impulsivity, hopelessness, depressive symptomatology, and sociodemographic factors vis-à-vis suicide-related ideation among older adults at risk of self-harm. Method:A sample (n = 117) of older adults was recruited from multiple sources for this study over a 1-year period. Suicide-related ideation was measured with the Geriatric Suicide Ideation Scale, a multidimensional measure of suicide-related ideation developed for use with older adults.Results: Canonical correlation identified 2 pairings of linear composites in which impulsivity emerged along both as significantly associated with facets of suicide-related ideation. Of note, the greater proportion of variance in impulsivity was subsumed along the second set of vectors with somatic depressive symptoms. Conclusion:Our findings suggest that the impulse to self-harm may be even more pronounced among older adults less likely to present as typically depressed. It is further suggested that impulsivity is more broadly associated with suicide-related ideation than hopelessness, and that screening for impulsivity as well as hopelessness may increase clinicians' ability to identify older adults at greatest risk of self-harm.Can J Psychiatry. 2009;54(10):684-692. Clinical Implications· Suicide-related ideation is significantly associated with hopelessness, depressive symptomatology, and impulsivity. · At-risk older adults who are more impulsive may be less likely to appear depressed. · Assessing impulsivity in addition to hopelessness could aid in suicide prevention and intervention. Limitations· A predominantly Caucasian, female, self-selected sample may limit generalizability of findings. · A single recruitment source might have yielded different outcomes as opposed to multiple sources. · Canonical correlation is more exploratory than hypothesis-driven modes of analysis.

Objectives: Prevalence rates of death by euthanasia (EUT) and physician-assisted suicide (PAS) have considerably increased in older adults, and public debates on these practices are still taking place. In this context, it seemed important to conduct a systematic review of the predictors (demographic, physical, psychological, social, quality of life, religious or existential) associated with attitudes toward, wishes and requests for, as well as death by EUT/PAS among individuals aged 60 years and over. Method: The search for quantitative studies in PsycINFO and MEDLINE databases was conducted three times until April 2018. Articles of probable relevance (n = 327) were assessed for eligibility. Studies that only presented descriptive data (n = 306) were excluded. Results: The review identified 21 studies with predictive analyses, but in only 4 did older adults face actual end-of-life decision making. Most studies (17) investigated attitudes toward EUT/PAS (9 through various hypothetical scenarios). Younger age, lower religiosity, higher education and socioeconomic status, were the most consistent predictors of endorsement of EUT/PAS. Findings were heterogeneous with regard to physical, psychological and social factors. Findings were difficult to compare across studies because of the large variety of outcomes measures and sample characteristics. Conclusion: Future studies should adopt common and explicit definitions of these concepts, as well as mixed longitudinal research designs that would allow for better consideration of various personal and social factors, and their interplays, on the decisionmaking process with regard to EUT/PAS.

This study based on provincial data points to tangible areas for preventative assessment by frontline home care professionals. Of interest were the risk and protective factors that differed by sex. As demand for home care in Canada is expected to increase, these findings may inform home care professionals' appraisal and approach to suicide prevention among community-residing older adults.

SUMMARYA systematic study of the winds in the upper atmosphere has been carried out during the 5-yr period 1953 to 1958. At heights of 85 to 100 km regular prevailing and periodic tidal wind components have been resolved. Components of the prevailing wind of about 20 m sec-' towards east are observed during the summer and winter months, with similar westward components during spring and weak westward winds in autumn. Large southward components of approximately 20 m sec are observed during the summer. The amplitude of the semi-diurnal periodic wind is also about 20 m sec-', and this component can usually be represented by a vector which rotates in a clockwise direction with constant amplitude twice every 21 hours. Large departures from this simple model occur at certain times of the year. Measurements of the 24-hr and 8-hr periodic wind systems are also described, and an upper limit of 2 m sec-l is determined for the lunar semidiurnal wind component.
