Group-based shame, guilt, and regret across cultures.

To date, there has been no systematic examination of cross-cultural differences in group-based shame, guilt, and regret following wrongdoing. Using a community sample ( = 1358), we examined people's reported experiences of shame, guilt, and regret following transgressions by themselves and by different identity groups (i.e.

How to live in peace? Mapping the science of sustaining peace: A progress report.

Despite good faith attempts by countless citizens, civil society, governments, and the international community, living in a sustainably peaceful community continues to be an elusive dream in much of our world. Among the challenges to sustaining peace is the fact that few scholars have studied enduringly peaceful societies, or have examined only narrow aspects of them, leaving our understanding of the necessary conditions, processes and policies fragmented, and deficient. This article provides a work-in-progress overview of a multidisciplinary, multimethod initiative, which aims to provide a holistic, evidence-based understanding of how peace can be sustained in societies.

Aggression prevention and reduction in diverse cultures and contexts.

It is not as difficult to prevent and reduce violence as commonly assumed. The examination of peaceful societies and nonviolent social movements provides insight on how core values and norms like humility, respect for others, love and caring, forgiveness, and patience are fundamental in promoting peace. Additionally, nonviolent attitudes actualized through nonviolent models and non-punitive childrearing practices can help socialize children to become nonviolent adults.

Lethal aggression in mobile forager bands and implications for the origins of war.

It has been argued that warfare evolved as a component of early human behavior within foraging band societies. We investigated lethal aggression in a sample of 21 mobile forager band societies (MFBS) derived systematically from the standard cross-cultural sample. We hypothesized, on the basis of mobile forager ethnography, that most lethal events would stem from personal disputes rather than coalitionary aggression against other groups (war).

Life without war.

An emerging evolutionary perspective suggests that nature and human nature are less "red in tooth and claw" than generally acknowledged by a competition-based view of the biological world. War is not always present in human societies. Peace systems, defined as groups of neighboring societies that do not make war on each other, exist on different continents.

A regional waterway management system for balancing recreational boating and resource protection.

Florida's coasts have been transformed over the past three decades as population growth and unprecedented demand for individual shore access to bays and estuaries led to the creation of residential canal developments. Thousands of miles of channels and basins were dredged as a by-product of this urbanization process. The navigable waterways that resulted are now being stressed by increasing boat traffic and canal-side activities.

Synthetic Studies in Phytochrome Chemistry.

An account is given of the author's several approaches to the synthesis of the parent chromophore of phytochrome (1), a protein-bound linear tetrapyrrole derivative that controls photomorphogenesis in higher plants. These studies culminated in enantioselective syntheses of both 2R- and 2S-phytochromobilin (4), as well as several (13)C-labeled derivatives designed to probe the site of Z,E-isomerization during photoexcitation. When reacted in vitro, synthetic 2R-4 and recombinant-derived phytochrome apoprotein N-C produced a protein-bound chromophore with identical difference spectra to naturally occurring 1.

Patterns and universals of mate poaching across 53 nations: the effects of sex, culture, and personality on romantically attracting another person's partner.

As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching--romantically attracting someone who is already in a relationship--was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was relatively infrequent in Africa, South/Southeast Asia, and East Asia. Evolutionary and social-role hypotheses received empirical support.

Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents, and 13 islands.

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated.

Studies on the Synthesis of Phytochrome and Related Tetrapyrroles. Dihydropyrromethenones by Photochemical Rearrangement of N-Pyrrolo Enamides.

Dihydropyrromethenone 67b, a potential precursor for the synthesis of phytochrome 1, has been prepared in enantiomerically pure form beginning with N-aminopyrrole 64 and the acetylenic acid 62b. The key step involved a 3,5-sigmatropic rearrangement of N-pyrrolo enamide 66b.
