How did authors control the literary fates of fictional characters before the existence of copyright? Could a second author do anything with another author’s character? Situated between the decline of the privilege system and the rise of copyright, literary borrowing in eighteenth-century Germany has long been considered unregulated. This book tells a different story. Characters before Copyright documents the surprisingly widespread eighteenth-century practice of writing fan fiction—literary works written by readers who appropriate preexisting characters invented by other authors—and reconstructs the contemporaneous debate about the literary phenomenon. Like fan fiction today, these texts took the form of sequels, prequels, and spinoffs. Analyzing the evolving reading, writing, and consumer habits of late-eighteenth-century Germany, Characters before Copyright identifies the social, economic, and aesthetic changes that fostered the rapid rise of fan fiction after 1750. Based on archival work and an ethnographic approach borrowed from legal anthropology, this book then uncovers the unwritten customary norms that governed the production of these works. Characters before Copyright thus reinterprets the eighteenth-century “literary commons,” arguing that what may appear to have been the free circulation of characters was actually circumscribed by an exacting set of rules and conditions. These norms translated into a unique type of literature that gave rise to remarkable forms of collaborative authorship and originality. Characters before Copyright provides a new perspective on the eighteenth-century book trade and the rise of intellectual property, reevaluating the concept of literary property, the history of moral rights, and the tradition of free culture.

In promoting biodiversity conservation and ecosystem service capacity, landscape connectivity is considered a critical feature to counteract the negative effects of fragmentation. Under a Green Infrastructure (GI) perspective, this is especially true in rural and peri-urban areas where a high degree of connectivity may be associated with the enhancement of agriculture multifunctionality and sustainability. With respect to GI planning and connectivity assessment, the role of dispersal traits of tree species is gaining increasing attention. However, little evidence is available on how to select plant species to be primarily favored, as well as on the role of landscape heterogeneity and habitat quality in driving the dispersal success. The present work is aimed at suggesting a methodological approach for addressing these knowledge gaps, at fine scales and for peri-urban agricultural landscapes, by means of a case study in the Metropolitan City of Rome. The study area was stratified into Environmental Units, each supporting a unique type of Potential Natural Vegetation (PNV), and a multi-step procedure was designed for setting priorities aimed at enhancing connectivity. First, GI components were defined based on the selection of the target species to be supported, on a fine scale land cover mapping and on the assessment of land cover type naturalness. Second, the study area was characterized by a Morphological Spatial Pattern Analysis (MSPA) and connectivity was assessed by Number of Components (NC) and functional connectivity metrics. Third, conservation and restoration measures have been prioritized and statistically validated. Notwithstanding the recognized limits, the approach proved to be functional in the considered context and at the adopted level of detail. Therefore, it could give useful methodological hints for the requalification of transitional urban–rural areas and for the achievement of related sustainable development goals in metropolitan regions.

AbstractThe Asian citrus psyllid (ACP), Diaphorina citri, is a harmful pest of citrus trees that transmits Candidatus Liberibacter spp. which causes Huanglongbing (HLB) (citrus greening disease); this is considered to be the most serious bacterial disease of citrus plants. Here we detail an anatomical study of the external and internal anatomy (excluding the reproductive system) using micro-computed tomography (micro-CT). This is the first complete 3D micro-CT reconstruction of the anatomy of a psylloid insect and includes a 3D reconstruction of an adult feeding on a citrus leaf that can be used on mobile devices. Detailed rendered images and videos support first descriptions of coxal and scapus antennal glands and sexual differences in the internal anatomy (hindgut rectum, mesothoracic ganglion and brain). This represents a significant advance in our knowledge of ACP anatomy, and of psyllids in general. Together the images, videos and 3D model constitute a unique anatomical atlas and are useful tools for future research and as teaching aids.

Abstract Our linguistic communication often takes the form of creating texts. In this paper, we propose that creating texts or ‘texting’ is a form of joint action. We examine the nature and evolution of this joint action. We argue that creating texts ushers in a special type of joint action, which, while lacking some central features of normal, everyday joint actions such as spatio-temporal collocation of agency and embodiment, nonetheless results in an authentic, strong, and unique type of joint action agency. This special type of agency is already present in creating texts in general and is further augmented in creating texts through digital media. We propose that such a unique type of joint action agency has a transformative effect on the experience of our sense of agency and subjectivity. We conclude with the implications of the proposal for social cognition and social agency. The paper combines research in philosophy of mind with the emerging fields of digital humanities and text technology.

Different authors have suggested that Anabates pulvericolor Sclater, 1858 might be the valid nomen for Synallaxis propinqua Pelzeln, 1859 or for Synallaxis gujanensis huallagae Cory, 1919. However, due to doubts regarding the taxonomic identity of Anabates pulvericolor Sclater, 1858, of which the unique type is lost, neither of these nomina has been displaced by the senior nomen pulvericolor. Our analysis of the case reveals that Anabates pulvericolor Sclater, 1858 is correctly identifiable with Synallaxis gujanensis huallagae Cory, 1919, of which it is a senior subjective synonym. According to the Code, the senior subjective synonym Synallaxis gujanensis pulvericolor (Sclater, 1858) should be adopted. Given the fact that the holotype of Anabates pulvericolor Sclater, 1858 is missing and that it has been impossible to identify it from its description until now, we designate a neotype from“Río Napo, Ecuador”, its original type locality.

Shed Light

The Albanian scholar Muḥammad Nāṣir al-Dīn al-Albānī (d. 1999) established a unique type of Salafism, a movement whose adherents follow a puritanical model of Muslim creed, exegesis, and conduct that is critical of madhhab Traditionalism. In this article I present an annotated translation of an audio lecture in which Albānī attempted to defend Salafism against its anti-madhhab image. I shed light on the religious and social climate that played a critical role in triggering Albānī’s disdain for Traditionalism and led him to discredit madhhab Traditionalist fiqh and replace it with his own interpretation of the jurisprudential requirements of Islamic scripture. Among the arguments I make is that Albānī’s claim to follow only the Qurʾān and Sunna is a rhetorical strategy designed to present Salafism as the absolute truth and distinguish it from being categorized as another madhhab or religious movement.

Digestive Glands

Tbe circulatory system, lying in the mid-dorsal line of the body, consists of an oval heart, the opthalmic artery, and a dorsal abdominal artery.The digestive system comprises a wide, large alimentary tube and two pairs of digestive glands. An oesophagus, a proventriculus, midgut, and a short proctodacum or hindgut form the digestive tube. The digestive glands are very well developed and are beaded in form; each pair lies on either side of the alimentary canal.The reproductive organs are well developed in both sexes: in the male they consist of paired testes and their vas deferentia, and in the female paired bilobed ovaries and oviducts.A cerebral or supraoesophageal ganglion, a suboesophageal ganglion, and seven thoracic ganglia form the nervous system. The supraoesophageal ganglion is united with the suboesophageal ganglion by means of the circumoesophageal commissures, whereas the thoracic ganglia and suboesophageal ganglia are linked with each other by paired connectives.The gills and the tracheae are the organs of respiration. The gills are borne of the bases of the pleopods and are enclosed in the branchial chamber. The tracheae are located on the lateral lobes of the first two pleopods only.

Mulitple Sclerosis

The interferons (IFN) are a family of complex proteins possessing antiviral, antiproliferative, and immunomodulatory activities. Two type 1 recombinant human IFN have been recently approved for the treatment of multiple sclerosis (MS). However, use of high dose type 1 IFN treatment in MS patients has been limited by dose-related toxicity. Ovine IFNt is a unique type 1 interferon discovered for its role in the animal reproductive cycle. It differs from other type 1 IFNs in that it is remarkably less toxic even at high concentrations, is able to cross species barriers, and is not inducible by viral infection. Ovine IFNt has been shown to be very effective in the treatment of animal models of MS. In this study, we examined the toxicity of OvIFNt on human T-cells at high doses and its immunregulatory properties at equivalent doses. Our experiments confirmed the remarkably non-toxic nature of OvIFNt on human cells at high concentrations as well as immunomodulating properties consistent with other type 1 IFNs including an antilymphoproliferative effect and inhibition of IFNg-induced HLA class II expression. These results suggest that OvIFNt could be developed into a potentially less toxic therapeutic option for immune-mediated disorders including MS.
