1. Peers in the Field: The Role of Ability and Gender in Peer Effects among Agricultural Workers

Author:
Hill, Alexandra E.; Burkhardt, Jesse

Abstract:
... This article presents evidence on peer effects among U.S. agricultural workers. On average, we find that a 10% increase in peer productivity increases focal worker productivity by 2.8%. This effect is modified by the ability and gender of workers and peers. Exceptionally slow workers are least responsive to peers and have pronounced negative spillovers on the productivity of their coworkers—their ...

Abstract:
... Due to the lack of unequivocal scientific evidence, gonadectomy’s effects on dogs’ behavior are still debated. Since veterinarians differ in their opinion, there may be considerable diversity in the advice received by owners. This study aimed to evaluate the effects of gonadectomy on dog behavior across time. Ninety-six dog owners (48 control dogs and 48 experimental dogs) were interviewed twice ( ...

Abstract:
... Reports suggest that 12–76% of adolescents have experienced parental comments regarding their weight/shape and/or eating behaviours. Parents may engage in conversations about weight/shape and eating out of concern, even without any ill intent; however, the associations of these comments with subsequent problematic psychosocial and eating behaviours are evidenced. Therefore, an in-depth understandi ...

Abstract:
... Numerous studies have shown that territorial animals exhibit less aggression in response to neighbours than to strangers, a phenomenon known as dear enemy effect. The influence of acoustic features, such as song type sharing and repertoire sizes, in neighbour recognition has been widely documented in male songbirds. However, few studies have focused on duetting species, and particularly on those w ...

Abstract:
... Sexual pheromones are chemical molecules responsible for mediating sex recognition and mating events. Long- and close-range sexual pheromones act differently. The first type is released to attract potential partners, whereas the second coordinates the interactions after potential mating partners encounter each other. Cuticular hydrocarbons (CHCs) have been suggested to be important cues in the mat ...

Abstract:
... Chronic social defeat stress (CSDS) is widely applied to study of depression in rodents. 10-day CSDS was a most commonly employed paradigm but with high resilience ratio (∼30%), producing potential variation in depression-like behavioral symptoms. Whether prolonged period (21 days) of CSDS would promote less resilience and reduce behavioral variability remains unknown. We applied 10-day and 21-day ...

Abstract:
... Despite recognition that colour can vary continuously, colour expression in colour polymorphic species is usually treated as discrete. We conducted three experiments to evaluate the extent that discrete and continuous male coloration influenced female mating preferences in long-tailed brush lizards (Urosaurus graciosus). Each experiment provided females with a different social context: a dimorphic ...

We recently showed that the treatment with Resveratrol (RES) contrasts the effects of ageing on the skeletal muscle (SKM), reduces the appearance of tubular aggregates (TAs), and improves the fatigue resistance. Since fatigue resistance depends on the SKM capillary network, and RES has been described to improve vascularisation, we analysed the SKM capillarization in naturally ageing C57BL/6J male ...
