Edge effects in fragmented natural habitats may De exaceroateci by intensive land use in the surrounding landscape. Given that most managed systems have higher primary productivity than adjacent natural systems, theory suggests that bottom-up subsidized consumers are likely to spill over from managed to natural habitats. Furthermore, the magnitude of spillover is likely to differ between genera...

A recent surge of research has investigated the potential of pro-environmental behavior interventions to affect other pro-environmental behaviors not initially targeted by the intervention. The evidence evaluating these spillover effects has been mixed, with some studies finding evidence for positive spillover (i.e., one pro-environmental behavior increases the likelihood of performing addition...

This study examines the link between negative work-family spillover and metabolic risk factors over a 9-year period. Data from two waves of the Midlife in the United States Survey were used to explore relationships between negative work-family spillover and four indicators of metabolic syndrome-blood pressure, triglycerides, body mass index, and glucose levels. In a sample of full-time working ...

BACKGROUND Despite the widespread use of tyramine as a pharmacological tool to assess the effects of norepinephrine release from sympathetic nerve terminals, its vascular effects are not adequately characterized. In particular, previous results indicate that intravenous tyramine produces little if any systemic vasoconstriction, suggesting that tyramine does not cause significant norepinephrine ...

The objective of this paper is to examine the structure of technology spillover from UAV (Unmanned Air Vehicle) technology on other industries by analyzing patents. The network analysis of the USPTO (United Stated Patents and Trademark Office) patent data from 1981 to 2000 was adopted to investigate the characteristic change of the technology spillover. The results show that the influence of UA...

ABSTRACT This study explores the short-run spillover effects of popular research papers. We consider the publicity of 'Male Organ and Economic Growth: Does Size Matter?' as an exogenous shock to economics discussion paper demand, a natural experiment of a sort. In particular, we analyze how the very substantial visibility influenced the downloads of Helsinki Center of Economic Research discussi...

Peer influence and social interactions can give rise to spillover effects in which the exposure of one individual may affect outcomes of other individuals. Even if the intervention under study occurs at the group or cluster level as in group-randomized trials, spillover effects can occur when the mediator of interest is measured at a lower level than the treatment. Evaluators who choose groups ...
