Patterns of volatile diversity yield insights into the genetics and biochemistry of the date palm fruit volatilome

Jonathan Flowers, Khaled Hazzouri, Alain Lemansour, Tiago Capote, Muriel Gros-Balthazard, Sylvie Ferrand, Marc Lebrun, Khaled Amiri & Michael Purugganan
Volatile organic compounds are key components of the fruit metabolome that contribute to traits such as aroma and taste. Here we report on the diversity of 90 flavor-related fruit traits in date palms (Phoenix dactylifera L.) including 80 volatile organic compounds, which collectively represent the fruit volatilome, as well as 6 organic acids, and 4 sugars in tree-ripened fruits. We characterize these traits in 148 date palms representing 135 varieties using headspace solid-phase microextraction gas...

Political Cynicism

Gwyneth McClendon & Alexis Palmer
The level of distrust in leaders and institutions in the contemporary United States is palpable. There is scholarly and pundit concern about the impending demise of U.S. democracy if citizens refrain from participating in politics or participate but condition their political behavior and decisions on high levels of distrust. In two surveys (yet to be conducted), we propose to analyze and explore several possible patterns in reported cynicism and distrust among U.S.-based online respondents. Many...

Cheating Because They Can: The Role of Networks in Informal Governance (LIEPP Policy Brief, n°62)

Jennifer Larson
Settlers flocking to “boomtowns” on the American western frontier were faced with the same task that communities in weak states across the globe face: self-governance. Peer sanctions can enforce cooperation in these environments, but their efficacy depends on the social networks that transmit information from peer to peer. Peripheral network positions can generate such strong incentives to misbehave that persistent cheating obtains in equilibrium. Groups maintaining high levels of cooperation that face shocks to their...

A study of self-affirmation on secondary school students with hearing impairment in Nepal

The 2017 Rights of Persons with Disabilities Act prohibits discrimination and violence based on disability (Holmes et al., 2018; Prasai & Pant, 2018), and there are more than 350 inclusive education classes and 35 special education schools across the country (UNICEF, 2018). However, children with disabilities are still more likely to be susceptible to the...
