Steven Stack's ecological research on suicide applied to homicide

In a sample of 72 nations in 1980, birth rates proved to be the strongest predictor of national homicide rates.     

Attitudes related to work of adolescents in the United Kingdom and Japan

This study was designed to provide data for notions that differences in achievement motivation in different nations may contribute to differences in national rates of economic growth. The nations investigated were the United Kingdom and Japan as representatives of low and high rates of economic growth in the decades after the end of World War II. Data were collected from college students for motivations and attitudes related to work. British students had higher achievement motivation, while Japanese students had higher competitiveness motivation and strong money beliefs. Differences in career preference between the nations were also presented. The relationship between motivations and attitudes to work with career preference were examined for each nation.     

Correlates of age-adjusted national homicide rates

In 1980, the correlates of unadjusted and age-adjusted national homicide rates differed, so the age-structure of nations should be controlled for in cross-national studies.     

Threat and Right‐Wing Attitudes: A Cross‐National Approach

Threat relates to right‐wing ideological attitudes at the individual level. The present study aims to extend this relationship to the national level. More specifically, in a sample of 91 nations, we collected country‐level indicators of threat (including inflation, unemployment, gross national product, homicide rate, and life expectancy). Moreover, we analyzed data from the European and World Value Survey (total N = 134,516) to obtain aggregated country‐level indicators for social‐cultural and economic‐hierarchical right‐wing attitudes for each of these countries. In accordance with previous findings based on the individual level, a positive relationship between threat indicators and right‐wing attitudes emerged. This relationship was stronger than what was usually reported at the individual level. In the discussion, we focus on the mutually reinforcing influence at the individual and national levels in terms of right‐wing attitudes.     

Explaining Cross‐National Variation in the Effect of Higher Education on Religiosity

While sociologists have long argued that higher education has a secularizing influence, recent research emphasizes the moderating role of social contexts in the relationship between social class and religion. I extend this line of research by examining sources of cross‐national variation in the association between higher education and religiosity using survey data from more than 46,000 respondents in 39 nations. Multilevel models of a religiosity scale show (1) in the aggregate, higher education has a moderate, negative effect on the religiosity scale, (2) this effect varies considerably across nations, and (3) the negative effect of higher education on religiosity is most robust in relatively religious nations. These results demonstrate the importance of national contexts in moderating the effect of education on religiosity. The results also support a cultural diffusion argument that suggests that the highly educated are innovators and early adopters of secular behaviors but that low levels of religiosity then diffuse to less‐educated segments of a population as secularity becomes more common.     

The deterrent effect of capital punishment during the 1950s

This investigation examines the deterrence hypothesis of an inverse relationship between state execution rates and homicides. Although this question has received some attention in recent studies, the findings of these investigations are mixed. Cross-sectional analyses of states have typically shown execution and homicide rates to be positively associated, while at least two national time-series studies report support for the deterrence hypothesis. To test whether these divergent findings are result of the two different methodologies employed (cross-sectional vs. time-series), a methodology that combines the strengths of each is used in the present study. For the period 1950 to 1960, we examine cross-sectionally for states the relationship between changes in execution rates and changes in murder rates. This analysis does not find support for the deterrence argument for the certainty of the death penalty when a number of models of the execution rate--murder rate relationship are considered, and when a variety of imprisonment and socio-demographic factors are considered as control variables.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

Cross-national social ecology of intelligence and suicide prevalence: integration, refinement, and update of studies

This study integrates, refines, and updates previous findings pertaining to positive ecologic (population-level) associations between intelligence and suicide prevalence across nations by using corrected and revised national IQ estimates and, further, a quality-of-human-conditions index, both recently published by Lynn and Vanhanen. Across a global 85-nation sample of sex-specific total suicide rates and a Eurasian 48-nation sample of sex-specific elderly suicide rates, these were positively associated with updated national IQ estimates. The associations were stronger for the general population than for elderly persons, independent of the quality of human conditions, and notedly stronger in exponential fitting of suicide rates with national IQ than in linear fitting, thereby indicating that shifts or differences in national IQ correspond to proportional, not absolute, changes in suicide rates. Implications of these findings and the question of generalizability of such associations to the individual level are discussed.     

Children Who Murder: A Review

Despite considerable research on juvenile homicide, pre-adolescent homicide offenders have received less attention. This paper reviews the existing literature on preteen murderers in order to characterize the current state of research knowledge about this population, and draws on some of the work on adolescent homicide as well. The analysis of this literature considers historical context, methodological issues, previous attempts to classify youthful homicide offenders, and predictors of preteen homicidal behavior. While there is a high degree of heterogeneity within this population, several developmental similarities emerged across cases that were associated with the perpetration of homicide by preteens. A high percentage of preteen homicide offenders come from homes characterized by physical abuse, domestic violence, poor or absent parenting, and overall instability. Gun availability may have been a facilitating factor. Support for different etiologies of preteen versus adolescent homicide is weak. Recommendations for future research directions are offered.     

Cohabitation,marriage, and murder: Woman‐killing by male romantic partners

Using a national‐level US homicide database that includes more than 400,000 homicides committed from 1976‐1994, I calculated rates of uxoricide (the murder of a woman by her romantic partner) by type of relationship (cohabiting or marital), ages of the partners, and age difference between partners. Women in cohabiting relationships are about nine times more likely to be killed by their partner than are women in marital relationships. Within marital relationships, the risk of uxoricide decreases with a woman’s age. Within cohabiting relationships, in contrast, middle‐aged women are at greatest risk of uxoricide. Paralleling the uxoricide victimization rates, uxoricide perpetration rates are highest for young married men and for middle‐aged cohabiting men. Uxoricide risk generally increases with greater age difference between partners. These findings provide the first national‐level replication of uxoricide risk patterns reported for a national‐level Canadian sample. Discussion highlights future research directions, including identifying why women in cohabiting relationships incur greater risk of uxoricide than do women in marital relationships. Aggr.

Gun control, gun ownership, and suicide prevention

The relationship of the extent of gun ownership and the strictness of gun control laws to suicide and homicide rates in the nine major geographic regions of the United States was explored. Gun ownership, rather than the strictness of gun control laws, was found to be the strongest correlate of the rates of suicide and homicide by guns. Regions with a higher extent of gun ownership had higher rates of suicide and homicide by firearms.     

Violent crime and its relation to subjective social stress indicators: The case of Israel

Although the effects of objective social stressors on violent crime have been studied extensively, the effects of subjective perception of stress factors have been neglected in criminological research. The present study investigates the relationship between the subjective perception of external stress factors and homicide and robbery rates, within a stress model according to which the probability of violence as a reaction to stress will increase when social support systems fail or malfunction. In the present context, subjective perception of social stress is conceived as expressions of worry or dissatisfaction regarding cardinal life domains such as the economic, security, or political situation. Support systems are defined here in terms of national solidarity, which is expressed as positive (or improved) attitudes regarding the relations between various segments of the population. The data regarding the subjective indicators were derived from continuing surveys of representative samples of urban Israeli population during the years 1967–1985. Fourteen stress indicators and two solidarity indicators were included. The periods covered range from less than 4 years to more than 16 years. The theoretical model was generally supported by the findings: both homicide and robbery were found to be related to most of the stress indicators as predicted. The two solidarity indicators were in line with the model in respect of robbery but not homicide. The consistency of the findings with the model is particularly noteworthy in view of the great variation among the independent variables regarding the number of observations and periods of time covered. Some theoretical implications of the findings are discussed, and suggestions are made for future research.     

The Associations Between Infant Homicide,Homicide, and Suicide Rates: An Analysis of World Health Organization and Centers for Disease Control Statistics

Previous studies have found that rates of homicide of children aged under one (infant homicide) are associated with rates of suicide, but not with rates of homicide. Linear regression was used to examine associations among infant homicide, homicide, and suicide in samples of regions in the United States and other countries. Infant homicide rates were significantly and independently associated in all analyses with both total homicide and total suicide rates. The epidemiological evidence supports the clinical observation that infant homicides are due to a range of causes, including maternal mental illness, but are also related to the level of serious violence within a community.     

Crime and violence in Brazil: Systematic review of time trends,prevalence rates and risk factors

Between 1980 and 2010 there were 1 million homicides in Brazil. Dramatic increases in homicide rates followed rises in inequality, more young men in the population, greater availability of firearms, and increased drug use. Nevertheless, disarmament legislation may have helped reduce homicide rates in recent years. Despite its very high rate of lethal violence, Brazil appears to have similar levels of general criminal victimization as several other Latin American and North American countries. Brazil has lower rates of drug use compared to other countries such as the United States, but the prevalence of youth drug use in Brazil has increased substantially in recent years. Since 1990, the growth of the Brazilian prison population has been enormous, resulting in the fourth largest prison population in the world. Through a systematic review of the literature, we identified 10 studies assessing the prevalence of self-reported offending in Brazil and 9 studies examining risk factors. Levels of self-reported offending seem quite high among school students in Brazil. Individual and family-level risk factors identified in Brazil are very similar to those found in high-income countries.     

The Relationship between General Population Suicide Rates and the Internet: A Cross‐National Study

Internet Web sites and chat rooms have been reported both to promote suicides and have a positive beneficial effect on suicidal individuals. There is a paucity of studies examining the role of the Internet in general population suicide rates. The relationship between general population suicide rates and the prevalence of Internet users was examined in a cross‐national study using data from the World Health Organization and the United Nations Web sites. The prevalence of Internet users was significantly and positively correlated with general population suicide rates in both sexes. On multiple regression analysis the prevalence of Internet users was independently associated with general population suicide rates in males, and this independent relationship in females approached statistical significance. Caution should be exercised in the attribution of a causal relationship and the direction of this relationship because of the cross‐sectional and ecological study design whereby the findings are subject to ecological fallacy. However, the findings identify and support a need for further research.     

Eliminating national stereotypes: Direct versus indirect disconfirmation of beliefs in covariation

Two modes of disconfirmation of national stereotypes were compared. It was hypo-thesized that stereotypes should be revised either by stereotype-inconsistent cases from the primary target (i.e., direct disconfirmation) or by instances which belong to an alternative target but possess features stereotypic of the primary target (indirect disconfirmation). It was further predicted that politically liberal individuals would show greater change in their national stereotypes than conservatives. Two experiments were conducted in which the salience of directly and indirectly disconfirming information regarding different nations was manipulated. The results indicated that indirect disconfirmation generally had as much impact as direct disconfirmation, but that the effects were particularly visible among liberal participants. Conservatives tended to respond in a reactive manner which preserved or exaggerated their original views. A new theoretical framework for the study of stereotype change and implications for its application were discussed.     

Relationship of IQ to suicide and homicide rate: an international perspective

IQs were correlated with the z score of suicide rate minus z score of homicide rate using nine regions of the world--established market economies, formerly socialized Europe, India, China, other Asian nations, Sub-Saharan Africa, Latin America/Caribbean, Middle East Crescent, and the USA. Correlations were .85 and .83 with crude rates and age-adjusted rates, respectively. The homicide findings are consistent with previous research in individual countries showing that less intelligent persons commit homicide more often. However, the present findings of a positive correlation between IQ and suicide rates are the opposite of what has been found in the more definitive studies within countries. Explanations for the apparent paradox and for the findings more generally were offered.     

The Antecedent Impact of Culture and Economic Growth on Nations` Creativity and Innovation Capability

Even though the literature has widely examined culture’s effect on nations’ creativity and innovation level, it has done little to address the system theory’s perspective. However, as proponents of the system theory have argued, nations’ creativity and innovation is the cumulative effort of the various stakeholders who operate as a system, so any assessment of a nation’s creativity and innovation must consider these stakeholders’ role. This study examines the overlooked effect of culture on the broader system aspect of eighty nations’ creativity and innovationto ensure representation by both developed and developing countries. Structural equation modeling using partial least squares software is applied to analyze the data. The study found out that nations with individualist and low power distance cultural values have the highest creativity and innovation, and that a nation’s economic growth level moderates the impact of the individualist cultural value. Policymakers who seek to develop a strategy that promotes creativity and innovation at the national level benefit from these findings. Future research directions are suggested.     

Economic correlates of violent death rates in forty countries, 1962–2008: A cross-typological analysis

ObjectivesOur goal was to identify if there might be advantages to combining two major public health concerns, i.e., homicides and suicides, in an analysis with well-established macro-level economic determinants, i.e., unemployment and inequality.MethodsMortality data, unemployment statistics, and inequality measures were obtained for 40 countries for the years 1962–2008. Rates of combined homicide and suicide, ratio of suicide to combined violent death, and ratio between homicide and suicide were graphed and analyzed. A fixed effects regression model was then performed for unemployment rates and Gini coefficients on homicide, suicide, and combined death rates.ResultsFor a majority of nation states, suicide comprised a substantial proportion (mean 75.51%; range 0–99%) of the combined rate of homicide and suicide. When combined, a small but significant relationship emerged between logged Gini coefficient and combined death rates (0.0066, p < 0.05), suggesting that the combined rate improves the ability to detect a significant relationship when compared to either rate measurement alone. Results were duplicated by age group, whereby combining death rates into a single measure improved statistical power, provided that the association was strong.ConclusionsViolent deaths, when combined, were associated with an increase in unemployment and an increase in Gini coefficient, creating a more robust variable. As the effects of macro-level factors (e.g., social and economic policies) on violent death rates in a population are shown to be more significant than those of micro-level influences (e.g., individual characteristics), these associations may be useful to discover. An expansion of socioeconomic variables and the inclusion of other forms of violence in future research could help elucidate long-term trends.     

Islam and suicide

Suicide and homicide rates of a sample of 72 nations were associated with a cluster of social variables related to economic development but not with a cluster related to the proportion of Islamic adherents.
