The effects of leader negative emotions on evaluations of leadership in a crisis situation: The role of anger and sadness

While existing literature on leadership articulates the importance of leader emotion, there has been little attention to the potential roles of more specific emotions. Emotions such as anger and sadness have been linked to leaders in times of crisis. The current paper examined the effect of leader emotion on evaluations of leadership in the context of a failed product. In particular, we examined how the expression of anger and sadness influences the evaluation of leaders. Results revealed that a leader expressing sadness was evaluated more favorably than a leader expressing anger. We found that participants' emotion mediated the relationship between leaders' emotion and the evaluation of leaders. Furthermore, accepting responsibility for the crisis led to more favorable evaluations than not accepting responsibility.     

Description of a domestic violence measure for Puerto Rican gay males

A sample of 302 Puerto Rican gay males living in Puerto Rico and New York participated in this study with the objective of assessing the prevalence of domestic violence. A self-administered questionnaire was developed addressing issues of intergenerational violence, addictive behaviors, and domestic violence in three dimensions: emotional, physical, and sexual violence. The results concluded that close to half of the participants had experienced some sort of violence in their intimate relationships, have a history of being witness to domestic violence in their family of origin, and had identified in themselves and their families, addictive behaviors. Other variables measured are HIV and sexual coercion, drug and alcohol abuse, and levels of acculturation among participants living in the United States. The main objective of this work is to describe the development of the instrument used in the study. Based on the results of this study we describe the psychometric characteristics and content of the final questionnaire. Final recommendations are made for other researchers interested in doing domestic violence studies with Latino gay men and men who have sex with men.     

Provincial and cosmopolitan: floristic composition of a dryland urban river

High rates of intercontinental exchange of plant species have caused scientists to ask whether floristic areas with similar environments are undergoing global homogenization. We focused on riparian forests of the urban Salt River (Sonoran Desert, USA) to ask: (1) Is the forest dominated by cosmopolitan or provincial elements? (2) Which trees planted in the irrigated cityscape have established along the river? (3) Which types of restoration interventions have favored provincial species? We surveyed tree abundance, size and vigor in belt transects among five reaches that differed in degree of restoration, and obtained data on tree species composition of the urban landscape and pre-development riparian zone. Our results reveal the urban riparian forest to have many cosmopolitan elements, owing in part to spillover of trees from the cultivated cityscape (e.g., Acacia stenophylla, Vitex agnus-castus). Global spread of some regional (Neotropical) riparian taxa (e.g., Parkinsonia aculeata, Prosopis) also has contributed to the cosmopolitan status. Yet, the forests retain a distinct regional signature. Unintentional restoration of winter floods has allowed for regeneration of Salix gooddingii, a vernally-adapted provincial pioneer, although its long-term survivorship is restricted to limited micro-sites (storm drain outfalls). Urbanization-related changes in stream hydrogeomorphology explain increases in some regional species (e.g., Washingtonia spp.) that historically were excluded from the river.

Reaches restored by planting, weeding, watering, and geocountouring had the greatest abundance of provincial species and greatest floristic similarity to historic conditions.
