Study followed tracked over 1,500 older adults for a decade using three rounds of data from the National Social Life, Health and Aging Project. Led by Lissette Piedra, a professor of social work at the University of Illinois Urbana-Champaign; and James Iveniuk, a senior research scientist at the University of Chicago’s National Opinion Research Center; the team identified three types of social networks — enriched, focused and restricted — that reflected how socially connected people were as they aged and how their self-rated health was affected.

Lebanon’s democracy faces severe challenges due to political rivalry between parties. A recent study has revealed that the political communication strategy of Hezbollah—a major party in Lebanon—has significantly evolved during recent years. While the party became increasingly critical of rival parties during national crises and confrontations with Israel, it became more cooperative after diplomatic normalization of Iran–Saudi relationship and expressed more positive view of rivals during electoral campaigns.

New research from Incheon National University highlights that pedestrian and roadside facilities—modifiable during maintenance, such as sidewalks, crossing facilities, and street lighting—play a critical role in reducing crashes rather than geometric attributes that are fixed on the road design stage. The study suggests that road safety is shaped by the interaction of various design attributes, with safety outcomes influenced by dynamic factors like volumes and speeds.
