Online Social Networks: Human Cognitive Constraints in Facebook and Twitter provides new insights into the structural properties of personal online social networks and the mechanisms underpinning human online social behavior.

As the availability of digital communication data generated by social media is revolutionizing the field of social networks analysis, the text discusses the use of large- scale datasets to study the structural properties of online ego networks, to compare them with the properties of general human social networks, and to highlight additional properties.

Users will find the data collected and conclusions drawn useful during design or research service initiatives that involve online and mobile social network environments.

Provides an analysis of the structural properties of ego networks in online social networks Presents quantitative evidence of the Dunbar's number in online environments Discusses original structural and dynamic properties of human social network through OSN analysis

The Life of Saint Helia, a late ancient Latin hagiography of uncertain provenance, is a remarkable and virtually unknown text, of which a critical edition and English translation appear here for the first time, accompanied by an introduction and commentary. Written predominately in dialogue format, the Life records a lengthy and highly polemical debate between a young girl Helia and her mother regarding the relative merits of virginity and marriage, followed by a dialogue between Helia and a bishop and a debate between Helia and a judge. The arguments both for and against virginity are biblically based, and the text is notable for its citational density and exegetical creativity. The dramatic narrative that frames the dialogue appears to have been influenced by the apocryphal Acts of Paul and Thecla, while the speeches suggest familiarity with the virginity apologetics of Ambrose and Jerome; because the Life has is preserved in only two medieval manuscripts, both from northern Spain, a Priscillianist context of composition is possible. This lively work will be of great interest to students of hagiography, asceticism, women's history, and biblical exegesis.

Constantina, daughter of the fourth-century emperor Constantine who so famously converted to Christianity, deserves a place of her own in the history of Christianity. As both poet and church-builder, she was an early patron of the Roman cult of the virgin martyr Agnes and was buried ad sanctam in a sumptuously mosaicked mausoleum that still stands. What has been very nearly forgotten is that the twice-married Constantina also came to be viewed as a virgin saint in her own right, said to have been converted and healed of leprosy by Saint Agnes. This volume publishes for the first time critical editions and English translations of three Latin hagiographies dedicated to the empress, offering an introduction and commentaries to contextualize these virtually unknown works. The earliest and longest of them is the anonymous Life of Saint Constantina likely dating to the mid or late sixth century, reflecting a female monastic setting and featuring both a story of pope Silvester's instruction of Constantina and a striking dialogue between Constantina and twelve virgins who offer speeches in praise of virginity as the summum bonum. A second, slightly later work, On the Feast of Saint Constantia (the misnaming of the saint reflecting common confusion), is a more streamlined account apparently tailored for liturgical use in early seventh-century Rome; this text is reworked and expanded by the twelfth-century Roman scholar Nicolaus Maniacoria in his Life of the Blessed Constantia, including a question-and-answer dialogue between Constantina and her two virginal charges Attica and Artemia. These works will be of great interest to students of late ancient and medieval saints' cults, hagiography, monasticism, and women's history.

The first 'heretic' to be condemned to death at the end of IV century, Priscillian, sometime bishop of Avila, has generated much scholarly interest in early Christian studies since the rediscovery of his works in the nineteenth century. Early scholarly attention focussed on the question of Priscillian's heterodoxy. Was he really an orthodox thinker victimised by ecclesiastical politics or were the accusations of heresy fully grounded in his teachings? Recent scholarship has moved away from rigid categorisation of the individual and focussed on the social-political movement of Priscillianism, with a tendency to neglect the literary corpus. Marco Conti draws attention back to the writings and the theological reflections there contained. Published for the first time in one volume with facing page translation and systematic commentaries, The Complete Works provide invaluable material for better understanding the complex nature of this fascinating figure and the movement he inspired, a crucial example of early opposition to Ecclesiastical power. With an extensive introduction providing biographical and textual background information.

Cyclic nucleotide phosphodiesterases (PDEs) are promising targets for pharmacological intervention. Multiple PDE genes, isoform diversity, selective expression and compartmentation of the isoforms, and an array of conformations of PDE proteins are properties that challenge development of drugs that selectively target this class of enzymes. Novel characteristics of PDEs are viewed as unique opportunities to increase specificity and selectivity when designing novel compounds for certain therapeutic indications. This chapter provides a summary of the major concepts related to the design and use of PDE inhibitors.
