The market for paintings in the Venetian Republic from Renaissance to Rococò

We study the art market in the Venetian Republic from 1550 to 1750 analyzing the determinants of the prices (adjusted for the cost of living measured by the price of wheat) of figurative paintings. Reputation of the painters, size of the paintings and other quantifiable factors affect prices as expected. Other relevant factors include the placement of the paintings (on altars, ceilings or walls), whose impact reflects differences in demand elasticities. We find evidence of the law of one price confirming price equalization between high and low demand geographical destinations and between different subjects. Finally, in a Schumpeterian perspective, we relate the temporal trend of the price of a representative painting with waves of artistic innovations, whose peacks were in the 1500s and in the 1700s with a dark Baroque age in the intermediate century.

How knowledge brokers emerge and evolve: The role of actors’ behaviour

This article investigates how actors positioned in a network can evolve as knowledge brokers, as well as how they act to develop new brokerage roles. Our focus is on actor's behaviour while previous studies concentrate more on the structural and positional determinants of brokerage roles. This research combines brokerage roles with a broker's functions in an exploratory study of a small Italian comics publishing house. Over 20 years, the firm played different brokerage roles involving different actors at national and international levels. We find that if all brokerage roles involve transcoding functions, the ability to overcome transcoding obstacles, through the use of shared imprinting with receiving partners, could be useful for developing any brokerage role. Moreover, heterogeneity in the competences and industry experience of hired members of the management team could support the development of new brokerage roles, with differentiated effects on various brokers’ functions. If a brokerage role involves new actors with no previous allegiance, the status of the broker, signalled through network relations, can have significant impacts by indirectly communicating its superior knowledge. The proposed, emerging theoretical framework has direct implications for studies of knowledge brokers and innovation in social networks, as well as for entrepreneurship research.     

Neuromuscular control during stepping down in continuous gait in individuals with and without ankle instability

Abstract

Ankle sprains are a common injury and those affected are at a risk of developing chronic ankle instability (CAI). Complications of an acute sprain include increased risk of re-injury and persistent disability; however, the exact link between ankle sprains and chronic instability has yet to be elucidated. The purpose of this study was to investigate neuromuscular control (including kinematics, kinetics and EMG) during stepping down from a curb, a common yet challenging daily activity, in persons with ankle instability (n = 11), those with a history of ankle sprain without persistent instability, called ankle sprain “copers” (CPRs) (n = 9) and uninjured controls (CTLs) (n = 13). A significant group difference was noted as the CPR group demonstrated increased tibialis anterior activity in both the preparatory (pre-touchdown) and reactive (post-touchdown) phases when compared to healthy and unstable groups (P < 0.05). It follows that the CPR group also demonstrated a significantly less plantar-flexed position at touchdown than the other two groups (P < 0.05). This is a more stable position to load the ankle and this strategy differed from that used by participants with CAI and uninjured CTLs. These findings provide insight into the neuromuscular control strategies of CPRs, which may allow them to more appropriately control ankle stability following sprains.     

Early social communication development in infants with autism spectrum disorder

Social-communication differences are a robust and defining feature of autism spectrum disorder (ASD) but identifying early points of divergence in infancy has been a challenge. The current study examines social communication in 9- to 12-month-old infants who develop ASD (N = 30; 23% female; 70% white) compared to typically developing (TD) infants (N = 94, 38% female; 88% white). Results demonstrate that infants later diagnosed with ASD were already exhibiting fewer social-communication skills using eye gaze, facial expression, gestures, and sounds at 9 months (effect size: 0.42–0.89). Moreover, three unique patterns of change across distinct social-communication skills were observed within the ASD group. This study documents that observable social-communication differences for infants with ASD are unfolding by 9 months, pointing to a critical window for targeted intervention.
