Rates of homicide and suicide on major national holidays

Rates of U.S. homicides and suicides during 1972-1979 were higher on 7 major national holidays except one for homicides and were lower for suicides, except New Year's Day as Lester noted for 1972-1979.     

The underrecording of suicides in state and national records, Alaska, 1983-1984

Information on Alaskan suicides has come primarily from studies based upon records obtained from the Alaska Bureau of Vital Statistics and the National Center for Health Statistics (NCHS). To evaluate the accuracy of these statistics, state and national (NCHS) vital statistics records were searched for suicide deaths in Alaska in 1983-1984. Of 195 deaths meeting our case definition of suicide, only 141 (72%) appeared in state records and 112 (57%) appeared in NCHS records. Native suicides were more likely to be underrecorded than non-Native suicides, even after differences in recording district personnel were adjusted for. Errors resulted primarily from delayed determinations of the cause of death and failure to update the records.     

The "birthday blues" in a sample of major league baseball players' suicides

Among 74 major league baseball players known to have committed suicide, 17 occurred within 28 days of the players' birthdays as compared to an expected number of 11.4.     

Absolutism in diaries of suicides

Two diaries, one from a completed suicide and one from an attempted suicide, were examined for the use of three words indicating absolutist thinking (perfect, always, and never). The diary of the attempted suicide had a significantly higher frequency use of "never" (2.75 per 1,000 words versus 1.73) but not the other words.     

Sex differences in sympathy for attempted suicides

In a sample of 115 undergraduates, women expressed more sympathy for hypothetical attempted suicides than did men, but not more empathy or agreement with the actions. A history of considering suicide was not associated with judgments about attempting suicide.     

Sex differences in adolescent suicides in Norway, 1990-1992

All suicides in persons under 20 years in Norway in the time period 1990-1992 (99 males, 30 females) were included in a postmortem case-control study with seven controls for each suicide, focusing on gender differences. Few sex differences between the suicide completers were evident, in spite of the difference in suicide rates (M/F rate ratio = 3.0). Females more often attempted suicide (p = .05), more often wrote farewell notes (p = .03), and used less violent suicide methods (ns). The adjusted risk for suicide related to affective disorders (Female OR = 22,1; Male OR = 24.0, both p = .000) and disruptive disorders (female OR = 14,7, ns; male OR = 5.0, p = .002) differed little, as did the effect of frequent use of alcohol or substances (female OR = 0.4, ns; male OR = 0.4, ns).     

黄泉路上走来回

这是很多年以前的事了。一天,四弟的电话来了,说:“父病重已难医治,他在世时日不多,急着要向你交代后事。”如此我只好火速回故乡探父病。我一到父亲的病榻前,见父亲已瘦得皮包骨头,四弟说他已有数日不进食也不肯吃药。父亲见到我似乎要急着交代后事,他上气不接下气地说:“你母亲已经来看过我,我去阴司要同你母亲住一起,不愿和你继母住一起。你是老大,这事你须在我去黄泉路前办好。”故乡所处山区,1994年时这个县还没有搞丧葬改革,城乡一律是土葬,故父亲和继母早在和睦时已建寿坟。后来因父亲和继母感情不好而分居了。现在病重,提出要和母亲…     

Comparison of suicides among Anglos and Hispanics in five southwestern states

Little is known about deaths resulting from self-inflicted violent behavior for Hispanic Americans. To learn more about suicide for Hispanics of Mexican origin (Mexican Americans) we focused on the five southwestern states (Arizona, California, Colorado, New Mexico, and Texas) in which more than 60% of all Hispanics in the United States reside (86% of whom are Mexican American). We obtained data on the number of suicide deaths in the white population, with Hispanics and Anglos (white, non-Hispanic) identified separately. Suicides of Anglos were used as a comparison group. Results show that the suicide rate for whites in the five southwestern states (15.6) was almost one-fourth higher than the rate for whites nationally (12.7). Suicide rates for the two ethnic groups, however, showed the rate for Hispanics (9.0) to be less than the national rates for whites (12.7) and one-half that of Anglos residing in the same area (17.3). The lower suicide rate for Hispanics relative to Anglos is seen for both males and females. The ratio of male and female suicides for Hispanics was almost twice that for Anglos (4.0 to 1 for Hispanics and 2.3 to 1 for Anglos). More than 1 in 3 Hispanic men who committed suicide and more than 1 in 4 Hispanic women who committed suicide are under the age of 25.     

Completed suicides in Colorado: differences between Hispanics and non-Hispanic Whites

All suicides by Hispanics (n = 434) and non-Hispanic Whites (n = 3,370) in Colorado from 2004 to 2008 using the Violent Death Reporting System were examined. Hispanic victims were significantly younger. Adjusting for age and gender, Hispanic victims were less likely to have reported depressed mood [odds ratio (OR) 0.78; 95% confidence interval (CI) 0.63-0.97], mental health diagnosis (OR 0.53; 95% CI 0.41-0.7), or current psychiatric treatment (OR 0.47; 95% CI 0.43-0.77). There were no differences in reports of financial, relationship, job, or legal stresses. Hispanic suicides were equally likely to be by overdose, firearm, or hanging, but more likely to be in jail (OR 2.68; 95% CI 1.55-4.65). To prevent suicides, stronger partnerships are needed among public health, medical, mental health, and criminal justice professionals.     

A national study of ethics committees

Conceived as a solution to clinical dilemmas, and now required by organizations for hospital accreditation, ethics committees have been subject only to small-scale studies. The wide use of ethics committees and the diverse roles they have played compel study. In 1999 the University of Pennsylvania Ethics Committee Research Group (ECRG) completed the first national survey of the presence, composition, and activities of U.S. healthcare ethics committees (HECs). Ethics committees are relatively young, on average seven years in operation. Eighty-six percent of ethics committees report that they played a role in ongoing clinical decision making through clinical ethics consultation. All are engaged in developing institutional clinical policy. Although 4.5% of HECs write policy on managed care, 50% of HEC chairs feel inadequately prepared to address managed care. The power and activity of ethics committees parallels the composition of those committees and the relationship of members to their institutions. The role of ethics committees across the nation in making policies about clinical care is greater than was known, and ethics committees will likely continue to play an important role in the debate and resolution of clinical cases and clinical policies.     

A central performance drop with luminance stimuli requiring spatial integration

This study reports four experiments that analyzed detection performance for luminance contrasts as a function of retinal eccentricity in order to find further support and explanations for the central performance drop (CPD) in the fovea. In the first experiment, 10 participants (16-37 years of age) had to detect a target patch in a stimulus consisting of bright and dark pixels. Luminance differences between target and context areas were achieved by placing a different number of bright (and dark) pixels in the target and the context area. Results showed a marked CPD; that is, performance did not peak in the fovea but in the parafovea. A spatial integration hypothesis was proposed to explain this CPD. Alternative explanations were tested in three further experiments with a total of 28 participants from 19-46 years of age (using the decision criterion effect, the selective masking effect, and inhibition by high frequencies). The findings did not contradict the spatial-integration hypothesis.     

Juvenile homicide: A growing national problem

Arrests for juvenile homicide more than doubled from 1984 to 1991. The present study examined offense characteristics for a national sample of 2,400 juvenile homicide offenders listed in the FBI Supplemental Homicide Reports for 1984 or 1991. Analyses indicate that the largest increases in juvenile homicide can be found among minority males using handguns to kill acquaintances. Juvenile homicides committed in the course of another crime (such as robbery or drug deal) have increased over 200%, while homicides precipitated by an interpersonal conflict with the victim have increased 83%. In comparison to adults, juvenile homicide offenders are much more likely to use a handgun and to act with an accomplice. These results highlight the association between handguns and juvenile homicide.     

Menninger's motives for suicide in the notes of completed and attempted suicides.

Brevard, Lester, and Yang in 1990, studying Menninger's motives for suicide, reported more evidence for the wish to be killed (i.e., self-blame or self-punishment) in suicide notes for completed suicides than in parasuicide notes for attempted suicide; however, they did not control for age and sex. A comparison of notes written by completed and attempted suicides that controlled for age and sex showed no differences in the presence of content which reflected Menninger's three motives for suicide, including the wish to be killed.     

COGNET: A national network for cognitive science

A planning committee funded by the Alfred P. Sloan Foundation has agreed in principle on a draft proposal for the establishment of a national network of computers for research in cognitive science. The main ideas of the proposal are discussed in this paper.
