Open source software development has evolved beyond single projects into complex networked ecosystems of projects that share portions of their code, social norms, and developer communities. This networked nature allows developers moving into a new project to easily leverage knowledge about process and social norms along with reputation gained in related projects. In this paper we examine a subs...

Privacy and security are major concerns for many users of social media. When users share information (e.g., data and photos) with friends, they can make their friends vulnerable to security and privacy breach with dire consequences. In our recent work, we show that it is feasible to measure user vulnerability and reduce one’s vulnerability without changing the structure of a social networking s...

This situation is problematic because apathy is associated with several adverse outcomes, including caregiver distress and decreased treatment adherence. This study investigated the prevalence of apathy and depression in 10 outpatients (7 women, 3 men, mean age = 63.7 years) at a Sout...

equatorial/axial conversion in piperidine and phosphorinane with different substituents wereinvestigated with great details. three possible routes, i.e. heteroatom inversion and two ring inversiontype were considered. ring conversion can occur via two pathways one starts with ring flatteningfrom the heteroatom site (nitrogen in piperidine and phosphorous in phosphorinane) and the otherinitiates...

Introduction: One of the most prominent features of Mars is the global south to north slope of ~0.036° [1] discovered by analysis of data from the Mars Orbiter Laser Altimeter (MOLA) aboard Mars Global Surveyor. In contrast, Isidis Planitia, the floor of Isidis basin, slopes southwest at an angle of ~0.02° [2]. It has been suggested [3] that deflection of the lithosphere under a load located in...

Psychiatric and neurological disorders have historically provided key insights into the structure-function relationships that subserve human social cognition and behavior, informing the concept of the 'social brain'. In this review, we take stock of the current status of this concept, retaining a focus on disorders that impact social behavior. We discuss how the social brain, social cognition, ...
