Urban ecosystem Services in Latin America: mismatch between global concepts and regional realities?

Urban Ecosystems - Latin America and the Caribbean (LAC) is one of the most urbanized and biologically diverse regions in the world but is often characterized by weak environmental governance and...     

Philanthropic styles

The challenge of resource development, particularly among major donors, has led nonprofits to adopt marketing techniques, including market segmentation. The benefit segmentation approach used in this study of the giving motivations of 218 major donors reveals seven philanthropic styles: (1) Communitarians, (2) the Devout, (3) Investors, (4) Socialites, (5) Repayers, (6) Altruists, and (7) Dynasts. Examples of how knowledge of philanthropic styles can aid in nonprofit resource development are provided.     

The impact of negotiated exchange on trust and trustworthiness

Negotiated exchanges and trust problems can be regarded as two different forms of exchange, the former representing exchanges with negotiation and binding contracts, the latter representing asymmetric transactions in which one actor has the opportunity to deceive the other. Both forms of exchange have been extensively studied, but the two respective research traditions exhibit very little overlap. In this paper, we investigate the effects of negotiated exchanges in different network structures on the development of mutual trust. We derive hypotheses from various theories and test them by means of an experiment in which subjects first undertake a series of negotiated exchanges under different power conditions, and then face a trust problem with one of the actors that have been involved in the previous exchanges. The trust problem is operationalized by means of the Investment Game which allows us to look separately at trust and trustworthiness. Our results demonstrate that negotiated exchanges increase mutual trust, but not trustworthiness.     

The relationship between sexual abuse and drug use: findings from Houston's Safer Choices 2 program

Self-report drug use data were collected from 282 female alternative school students surveyed through the Safer Choices 2 study in Houston, Texas. Data collection took place between October 2000 and March 2001 via audio-enabled laptop computers equipped with headphones. Logistic regression analyses indicated that sexual abuse history was significantly associated with lifetime use (OR = 1.9, p < or = 0.05). While the relationships tested in this study are exploratory, they provide evidence for an important connection between sexual abuse and substance use among female alternative school students.     

Patterns of parental bereavement following the loss of a child and related factors

This study investigated the patterns of parental bereavement in 20 parents who have lost a child to cancer, congenital heart disease, meningitis, or drowning in the last 19 months, using semi-structured interviews and standardized questionnaires of depression and grief. Qualitative content analysis of interviews identified three bereavement patterns: The majority of parents (65%) presented uncomplicated, Integrated Grief five mothers were Consumed by Grief and one mother and one father expressed Minimal Grief. Quotes from parents exemplified these patterns. Parental gender, symptoms of depression, and pre-death relationship between parents and their deceased child differentially related to these patterns. Having surviving children, social support, and being active appeared to help to integrate grief into daily life. These findings illustrate differential patterns of parental bereavement and related factors, information that has important implications for identifying at-risk parents for complicated bereavement.     

Interparental Relations,Maternal Employment,and Fathering in Mexican American Families

This study examined independent and interactive relations between the interparental relationship and maternal employment in predicting fathering within low‐income, Mexican American two‐parent families (N = 115). Interparental conflict was negatively related to quality fathering, and these relations were noted only for single‐earner families. The parenting alliance was positively related to quality fathering irrespective of maternal employment. Fathering was associated with lower levels of child depression and conduct problems. Results suggest that bolstering quality fathering is a useful avenue for improving child well‐being and that strengthening the interparental relationship can support quality fathering and child mental health within Mexican American families.     

Weighted quantile regression with nonelliptically structured covariates

Although quantile regression estimators are robust against low leverage observations with atypically large responses (Koenker & Bassett 1978), they can be seriously affected by a few points that deviate from the majority of the sample covariates. This problem can be alleviated by downweighting observations with high leverage. Unfortunately, when the covariates are not elliptically distributed, Mahalanobis distances may not be able to correctly identify atypical points. In this paper the authors discuss the use of weights based on a new leverage measure constructed using Rosenblatt's multivariate transformation which is able to reflect nonelliptical structures in the covariate space. The resulting weighted estimators are consistent, asymptotically normal, and have a bounded influence function. In addition, the authors also discuss a selection criterion for choosing the downweighting scheme. They illustrate their approach with child growth data from Finland. Finally, their simulation studies suggest that this methodology has good finite‐sample properties.     

The Cognitive Impact of Sexual Abuse and PTSD in Children: A Neuropsychological Study

Sexual abuse is known to have an impact on both child and adult mental health, but the neuropsychological basis of this effect is still largely unknown. This study compared neuropsychological test results from a group of 76 children, 13 of them sexual abuse victims with symptoms of post-traumatic stress disorder, 26 victims of sexual abuse who showed no symptoms post-traumatic stress disorder, and 37 controls. The groups were matched by age, sex, socioeconomic status, and educational level. Child sexual abuse was associated with reduced ability to inhibit automatic responses measured by the Stroop test regardless of post-traumatic stress disorder status. These findings indicate possible attentional inhibition difficulties in child victims of sexual abuse, which may help explain psychopathology associated with the experience.     

Examining the Experiences of Fathers of Children with a Life-Limiting Illness

Families who have a child diagnosed with a life-limiting illness (LLI) face substantial challenges resulting from the complexity and devastating impact of the condition and potential closeness of death. The experiences of fathers of a child with LLI have been understudied; therefore, this study explored the stresses, experiences, and strategies of these fathers, including their perceptions about support needs. Based on grounded theory, in-depth semi-structured interviews were conducted with 18 fathers of children with LLI. Six fathers had experienced the death of their child. The overarching themes were stresses, means of coping, and perceived needs for support. Generally, fathers in this study struggled relative to discursive and internalized notions of fathers as providers and protectors for their children, combined with an inability to ease their child’s vulnerability to LLI. Participants were engaged in the care of their child with LLI, but several felt marginalized by health care providers in care planning and staff/family communication. Some fathers recognized and valued their support network while others had few supports. Some described personal growth and desired to help other fathers. Practice implications and recommendations include renewed application of family-centered care, overcoming presumptions about fathers’ roles, and recognizing the impact of LLI beyond physical health.
