Feeling Good about Giving: The Benefits (and Costs) of Self-Interested Charitable Behavior

In knowledge-intensive settings such as product or software development, fluid teams of individuals with different sets of experience are tasked with projects that are critical to the success of their organizations. Although building teams from individuals with diverse prior experience is increasingly necessary, prior work examining the relationship between experience and performance fails to find a consistent effect of diversity in experience on performance. The problem is that diversity in experience improves a team's information processing capacity and knowledge base, but also creates coordination challenges. We hypothesize that team familiarity - team members' prior experience working with one another - is one mechanism that helps teams leverage the benefits of diversity in team member experience by alleviating coordination problems that diversity creates. We use detailed project- and individual-level data from an Indian software services firm to examine the effects of team familiarity and diversity in experience on performance for software development projects. We find the interaction of team familiarity and diversity in experience has a complementary effect on a project being delivered on time and on budget. In team familiarity, we identify one mechanism for capturing the performance benefits of diversity in experience and provide insight into how the management of experience accumulation affects team performance.Diversity, Experience, Knowledge, Software, Team Familiarity

Prosocial Spending and Happiness: Using Money to Benefit Others Pays Off

While a great deal of research has shown that people with more money are somewhat happier than people with less money, our research demonstrates that how people spend their money also matters for their happiness. In particular, both correlational and experimental studies show that people who spend money on others report greater happiness. The benefits of such prosocial spending emerge among adults around the world, and the warm glow of giving can be detected even in toddlers. These benefits are most likely to emerge when giving satisfies one or more core human needs (relatedness, competence, and autonomy). The rewards of prosocial spending are observable in both the brain and the body and can potentially be harnessed by organizations and governments

Fuming Method for Micropatterning Structures on Langmuir- Blodgett Films

This document is the Accepted Manuscript version of a Published Work that appeared in final form in Langmuir, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://doi.org/10.1021/la804104k.Lipid monolayers of L-α-dipalmitoylphosphatidylcholine (DPPC) are used to pattern substrates using the Langmuir-Blodgett (LB) technique. Lipid monolayers are deposited onto a freshly cleaved mica surface or glass capillary under conditions that lead to distinct patterns in the film. Exposure of the supported monolayer to ethyl 2-cyanoacrylate fumes leads to preferential polymerization in the more hydrated regions of the patterned monolayer. This method enables surfaces to be micropatterned where the lateral features are controlled by the structure present in the underlying LB film and the vertical feature size is controlled by the length of the fuming process. Atomic force microscopy (AFM) measurements confirm that the original structure in the LB film is preserved following fuming and that the lateral and vertical feature sizes can be controlled from nanometers to microns. This method, therefore, provides a rapid and versatile approach for micropatterning both flat and curved surfaces on a variety of substrates

Making a Difference Matters: Impact Unlocks the Emotional Benefits of Prosocial Spending

When does giving lead to happiness? Here, we present two studies demonstrating that the emotional benefits of spending money on others (prosocial spending) are unleashed when givers are aware of their positive impact. In Study 1, an experiment using real charitable appeals, giving more money to charity led to higher levels of happiness only when participants gave to causes that explained how these funds are used to make a difference in the life of a recipient. In Study 2, participants were asked to reflect upon a time they spent money on themselves or on others in a way that either had a positive impact or had no impact. Participants who recalled a time they spent on others that had a positive impact were happiest. Together, these results suggest that highlighting the impact of prosocial spending can increase the emotional rewards of giving

The persuasive “power” of stigma

a b s t r a c t We predicted that able-bodied individuals and White Americans would have a difficult time saying no to persuasive appeals offered by disabled individuals and Black Americans, due to their desire to make such interactions proceed smoothly. In two experiments, we show that members of stigmatized groups have a peculiar kind of persuasive ''power'' in face-to-face interactions with non-stigmatized individuals. In Experiment 1, wheelchair-bound confederates were more effective in publicly soliciting donations to a range of charities than confederates seated in a regular chair. In Experiment 2, Whites changed their private attitudes more following face-to-face appeals from Black than White confederates, an effect mediated by their increased efforts to appear agreeable by nodding and expressing agreement. This difference was eliminated when impression management concerns were minimized -when participants viewed the appeals on video

On emotionally intelligent time travel: Individual differences in affective forecasting ability

available options would make them feel. Yet, recent research suggests that such predictions, or affective forecasts, often are inaccurate. There are, after all, a number of obstacles to successful emotional time travel-people are likely to err in affective forecasting if they inaccurately envision the future event itself, misremember how they felt in response to similar past events, or fail to adequately take into account the host of potential differences between their physical and psychological state at the time of forecasting and the time of experiencin

It's the Recipient That Counts: Spending Money on Strong Social Ties Leads to Greater Happiness than Spending on Weak Social Ties

Previous research has shown that spending money on others (prosocial spending) increases happiness. But, do the happiness gains depend on who the money is spent on? Sociologists have distinguished between strong ties with close friends and family and weak ties—relationships characterized by less frequent contact, lower emotional intensity, and limited intimacy. We randomly assigned participants to reflect on a time when they spent money on either a strong social tie or a weak social tie. Participants reported higher levels of positive affect after recalling a time they spent on a strong tie versus a weak tie. The level of intimacy in the relationship was more important than the type of relationship; there was no significant difference in positive affect after recalling spending money on a family member instead of a friend. These results add to the growing literature examining the factors that moderate the link between prosocial behaviour and happiness

Climate change alterations to ecosystem dominance: how might sponge-dominated reefs function?

Anthropogenic stressors are impacting ecological systems across the world. Of particular concern are the recent rapid changes occurring in coral reef systems. With ongoing degradation from both local and global stressors, future reefs are likely to function differently to current coral-dominated ecosystems. Determining key attributes of future reef states is critical to reliably predict outcomes for ecosystem service provision. Here we explore the impacts of changing sponge dominance on coral reefs. Qualitative modelling of reef futures suggests that changing sponge dominance due to increased sponge abundance will have different outcomes for other trophic levels compared with increased sponge dominance as a result of declining coral abundance. By exploring uncertainty in the model outcomes we identify the need to: i) quantify changes in carbon flow through sponges, ii) determine the importance of food limitation for sponges, iii) assess the ubiquity of the recently described 'sponge loop', iv) determine the competitive relationships between sponges and other benthic taxa, particularly algae, and v) understand how changing dominance of other organisms alters trophic pathways and energy flows through ecosystems. Addressing these knowledge gaps will facilitate development of more complex models that assess functional attributes of sponge-dominated reef ecosystems. This article is protected by copyright.

Skeletal accumulation of fluorescently-tagged zoledronate is higher in animals with early stage chronic kidney disease

This work examines the skeletal accumulation of fluorescently-tagged zoledronate in an animal model of chronic kidney disease. The results show higher accumulation 24-hours post-dose in animals with lower kidney function due to greater amounts of binding at individual surfaces.NIH F30 DK115162; NIH T32 AR065971; NIH P30 DK 07931
