Abstract A preliminary sample of contracts of apprenticeship from three periods in the history of early modern Venice is analysed, as recorded in the archive of the Giustizia Vecchia, a Venetian magistracy. The periods are the end of the 16th century, the 20s and the 50s of the 17th. First, the variety of professions represented in the dataset reduces over time, as the proportion of Venetian ap...

Morphology-based phylogenetic analyses support the monophyly of the Scalidophora (Kinorhyncha, Loricifera, Priapulida) and Nematoida (Nematoda, Nematomorpha), together constituting the monophyletic Cycloneuralia that is the sister group of the Panarthropoda. Kinorhynchs are unique among living cycloneuralians in having a segmented body with repeated cuticular plates, longitudinal muscles, dorso...

The origin and extreme diversification of the animal nervous system is a central question in biology. While most of the attention has traditionally been paid to those lineages with highly elaborated nervous systems (e.g. arthropods, vertebrates, annelids), only the study of the vast animal diversity can deliver a comprehensive view of the evolutionary history of this organ system. In this regar...

Sipuncula is a lophotrochozoan taxon with annelid affinities, albeit lacking segmentation of the adult body. Here, we present data on cell proliferation and myogenesis during development of three sipunculan species, Phascolosoma agassizii, Thysanocardia nigra, and Themiste pyroides. The first anlagen of the circular body wall muscles appear simultaneously and not subsequently as in the annelids...

Despite its uses, the Internet is liable to be abused. &&Internet Addiction'' is a newly proposed construct, derived form DSM-IV criteria for substance abuse. As a very recent phenomenon, excess internet use probably arises through pre-existing mechanisms. The addictive element may be the search for stimulation through interactive services, or the Internet may serve the purpose of an escape fro...

Being dominant factors driving the human actions, personalities can be excellent indicators in predicting the offline and online behavior of different individuals. However, because of the great expense and inevitable subjectivity in questionnaires and surveys, it is challenging for conventional studies to explore the connection between personality and behavior and gain insights in the context o...

The existence of a close relation between personality and drug consumption is recognized, but the corresponding causal connection is not well known. Neither is it well known whether personality exercises an influence predominantly at the beginning and development of addiction, nor whether drug consumption produces changes in personality. This paper presents a dynamic mathematical model of perso...

Khat leaves are cultivated in the highlands of the Horn of Africa, Southern Arabia and along the East African coast. In parts of Ethiopia, Kenya, Somalia and Yemen, khat leaves have been chewed for centuries for their mildly stimulating properties and are for many a regular part of social life. Traditionally, khat was used mostly by men during highly ritualised communal ‘khat parties’. Within a...

• Trait introverts report feeling authentic even when acting extraverted. Social identities about introversion–extraversion differ from the trait. Participants reported lower authenticity debating contrary to dispositions and identities. Counter-dispositional costs did not closely track moods. Research suggests that trait feel more We explored boundaries of this idea by assessing as introvert o...
