Nowadays, amaranth appears as a promising source of squalene of vegetable origin. Amaranth oil is indeed one of the most concentrated vegetable oils in squalene, i.e., up to 6% (w/w). This triterpene is highly appreciated in cosmetology, especially for the formulation of moisturizing creams. It is almost exclusively extracted from the liver of sharks, causing their overfishing. Thus, providing a squalene of renewable origin is a major challenge for the cosmetic industry. The amaranth plant has thus experienced renewed interest in recent years. In addition to the seeds, a stem is also produced during cultivation. Representing up to 80% (w/w) of the plant aerial part, it is composed of a ligneous fraction, the bark, on its periphery, and a pith in its middle. In this study, a fractionation process was developed to separate bark and pith. These two fractions were then used to produce renewable materials for building applications. On the one hand, the bark was used to produce hardboards, with the deoiled seeds acting as natural binder. Such boards are a viable alternative to commercial wood-based panels. On the other hand, the pith was transformed into cohesive and machinable low-density insulation blocks revealing a low thermal conductivity value.

The article considers two versions of D. H. Lawrence’s essay The Theatre: the one which appeared in the English Review in September 1913 and the other one which Lawrence published in his first travel book Twilight in Italy (1916). The latter, considerably revised and expanded, contains a number of new observations and gives a more detailed account of Lawrence’s ideas.Lawrence brings to life the atmosphere inside and outside the theatre in Gargnano, presenting vividly the social structure of this small northern Italian town. He depicts the theatre as a multi-storey stage, combining the interpretation of the plays by Shakespeare, D’Annunzio and Ibsen with psychological portraits of the actors and a presentation of the spectators and their responses to the plays as distinct social groups.Lawrence’s views on the theatre are contextualised by his insights into cinema and its growing popularity.What makes this research original is the fact that it offers a new perspective, aiming to illustrate the social situation inside and outside the theatre whichLawrenceobserved. The author uses the material that has never been published or discussed before such as the handwritten lists of box-holders in Gargnano Theatre, which was offered to Lawrence and his wife Frieda by Mr. Pietro Comboni, and the photographs of the box-panels that decorated the theatre inLawrence’s time.

This book highlights the importance of time and timing in economic and social development. ‘Compressed development’ consists of two key features and their interaction: the tendency for development processes to unfold more rapidly (compression) and the institution-shaping influences of major periods of change and growth, especially when countries become integrated into the global economy (era). Using an interdisciplinary conceptual framework of state–market and organization–technology co-evolution, the authors contrast the experiences of ‘early’ and ‘late’ developers such as the United Kingdom and Japan, with countries–most notably China–which have become more deeply integrated with the global economy since the 1990s. Compressed developers experience ‘thin industrialization’, layered types of employment, and ‘double burdens’ or challenges in social development. National development strategies must accommodate global value chains and powerful international actors on the one hand, and decentralization on the other. To cope, and thrive, states must remain developmental, whilst being increasingly engaged and adaptive in multiple levels of governance. Compressed Development explores the historical and contemporary features of economic and social development at the intersection of development studies and studies of globalization. By bringing a new perspective on the ‘middle-income trap’, as well as the emerging digital economy, and the state–market and geopolitical tensions that are currently upending conventional wisdoms, the book offers timely insights that will be useful, not only for students of development, but for policymakers, business, and labour organization seeking to navigate the rushing currents of contemporary capitalism.

In attempting to characterize Second Temple legends of the Hasmoneans, the concluding chapter identifies several distinct genres: fragments from Aramaic chronicles, priestly temple legends, Pharisaic legends, and theodicean legends explaining the fall of the Hasmonean dynasty. The chapter then examines, by generation, how Josephus on the one hand, and the rabbis on the other, reworked these embedded stories. The Josephan treatment aimed to reduce the hostility of the early traditions toward the Hasmoneans by imposing a contrasting accusatory framework that blames the Pharisees and justifies the Hasmonean ruler. The rabbinic treatment of the last three generations exemplifies the processes of rabbinization and the creation of archetypal figures. With respect to the first generation, the deliberate erasure of Judas Maccabeus’s name from the tradition of Nicanor’s defeat indicates that they chose to celebrate the Hasmonean victory but concealed its protagonists, the Maccabees, simply because no way was found to bring them into the rabbinic camp.

AbstractIn the Shuowen, one of the earliest comprehensive character dictionaries of ancient China, when discussing where the Chinese characters derive their structural components, Xu Shen proposed the dual constitutive principle of “adopting proximally from the human body, and distally from things around.” This dual emphasis of “body” and “things around” corresponds largely to the phenomenological issues of body or corporeality on the one hand, and lifeworld on the other. If we borrow Heidegger’s definition of Dasein as Being-in-the world, we can easily arrive at a reformulation of Xu Shen’s constitutive principle of the Chinese script as one that concerns “bodily Dasein.” By looking into various examples of script tokens we can further elaborate on how the Chinese make use not only of the body in general but various body parts, and how they differentiate their life world into material nature, living things, and a multifaceted world of equipment in forming a core basis of Chinese characters/components, upon which further symbolic manipulation such as “indication”, “phonetic borrowing”, semantic combination, and “annotative derivation”, etc. can be based. Finally, examples will be cited to show how in the Chinese scripts the human body (and its parts) might interact with other’s bodies (and their parts) or with “things around” (whether nature, living creatures, or artifacts) in various ways to cover the social, environmental, ritual, technical, economical, and even intellectual aspects of human experience. Bodily Dasein, so to speak, provides us with a new perspective of understanding and appreciating the entire scope of the Chinese script.

In 1976, in “Society Must be Defended,” Foucault did more than offer an alternative genealogy of his own genealogical perspective to the one he is sometimes taken to have provided in “Nietzsche, Genealogy, History.” He also, by implication, located Nietzsche within that genealogy, one result of which is that he gave what amounts to a new perspective on how Nietzsche might be placed within the history of racisms.

This article analyses the relation between European economic crisis and immigration. It does so by analysing the establishment of migrants’ entrepreneurship activities in Italy, and by looking at how these activities unravel subjects’ agency in confronting constraining socioeconomic conditions and restrictive immigration laws. In this perspective, entrepreneurship should be understood as a possibility for transforming a person’s own incorporated cultural capital into a resource and, consequently, into an opportunity for self-created work performance. Interpreting entrepreneurship as a personal response of migrants to the economic recession offers a new perspective in the existing literature on migrant entrepreneurship. Crisis, in this paper, is not seen as an abstract and supernatural phenomenon leading and controlling the capacity of individuals to act, but is understood as a constructed set of meanings comprising social interactions and relationships and consolidated within public discourses. This study is based on a qualitative-explorative research approach and was carried out in South Tyrol, Italy. For the data collection, different qualitative methods were used: narrative interviews, informal discussions and semi-structured interviews. Data analysis was based on the coding processes described within the Grounded Theory. As the results show, crisis as such represents, on the one hand, a critical moment of transition or transformation of normality and the constituted ways of acting and thinking and, on the other hand, it is perceived as a new opportunity to change individual behaviour and to initiate innovative counter-strategies that will maintain a person’s capacity to act even in critical personal and structural situations. Nevertheless, showing resilience, which is powerful and leads to change, depends not only on personal motivational forces but also to given opportunity structures.

AbstractNon-manipulable factors, such as gender or race have posed conceptual and practical challenges to causal analysts. On the one hand these factors do have consequences, and on the other hand, they do not fit into the experimentalist conception of causation. This paper addresses this challenge in the context of public debates over the health cost of obesity, and offers a new perspective, based on the theory of Structural Causal Models (SCM).

Abstract The following article argues that fictional texts can be distinguished from non-fictional texts in a prototypical way, even if the concept of the fictional cannot be defined in classical terms. In order to be able to characterize fictional texts, semantic, pragmatic, and reader-conditioned factors have to be taken into account. With reference to Frege, Searle, and Gabriel, the article recalls some proposals for how we might define fictional speech. Underscored in particular is the role of reception for the classification of a text as fictional. I make the case, from a philosophical perspective, for the view that fictional texts represent worlds that do not exist even though these worlds obviously can, and de facto do, contain many elements that are familiar to us from our world. I call these worlds reading worlds and explain the relationship between reading worlds and the life world of readers. This will help support the argument that the encounter with fictional literature can invoke real feelings and that such feelings are by no means irrational, as some defenders of the paradox of fiction would like us to believe. It is the exemplary character of fictional texts that enables us to make connections between the reading worlds and the life world. First and foremost, the article discusses the question of what it is that readers’ feelings are in fact related to. The widespread view that these feelings are primarily related to the characters or events represented in a text proves too simple and needs to be amended. Whoever is sad because of the fate of a fictive character imagines how he or she would fare if in a similar situation. He or she would feel sad as it relates to his or her own situation. And it is this feeling on behalf of one’s self that is the presupposition of sympathy for a fictive character. While reading, the feelings related to fictive characters and content are intertwined with the feelings related to one’s own personal concerns. The feelings one has on his or her own behalf belong to the feelings related to fictive characters; the former are the presupposition of the latter. If we look at the matter in this way, a new perspective opens up on the paradox of fiction. Generally speaking, the discussion surrounding the paradox of fiction is really about readers’ feelings as they relate to fictive persons or content. The question is then how it is possible to have them, since fictive persons and situations do not exist. If, however, the emotional relation to fictive characters and situations is conceived of as mediated by the feelings one has on one’s own behalf, the paradox loses its confusing effect since the imputation of existence no longer plays a central role. Instead, the conjecture that the events in a fictional story could have happened in one’s own life is important. The reader imagines that a story had or could have happened to him or herself. Readers are therefore often moved by a fictive event because they relate what happened in a story to themselves. They have understood the literary event as something that is humanly relevant in a general sense, and they see it as exemplary for human life as such. This is the decisive factor which gives rise to a connection between fiction and reality. The emotional relation to fictive characters happens on the basis of emotions that we would have for our own sake were we confronted with an occurrence like the one being narrated. What happens to the characters in a fictional text could also happen to readers. This is enough to stimulate corresponding feelings. We neither have to assume the existence of fictive characters nor do we have to suspend our knowledge about the fictive character of events or take part in a game of make-believe. But we do have to be able to regard the events in a fictional text as exemplary for human life. The representation of an occurrence in a novel exhibits a number of commonalities with the representation of something that could happen in the future. Consciousness of the future would seem to be a presupposition for developing feelings for something that is only represented. This requires the power of imagination. One has to be able to imagine what is happening to the characters involved in the occurrence being narrated in a fictional text, ›empathize‹ with them, and ultimately one has to be able to imagine that he or she could also be entangled in the same event and what it would be like. Without the use of these skills, it would remain a mystery how reading a fictional text can lead to feelings and how fictive occurrences can be related to reality. The fate of Anna Karenina can move us, we can sympathize with her, because reading the novel confronts us with possibilities that could affect our own lives. The imagination of such possibilities stimulates feelings that are related to us and to our lives. On that basis, we can participate in the fate of fictive characters without having to imagine that they really exist.

This study focuses on the ritual ‘conservatism’ of Henry VIII's Reformation through a new look at biblical exegeses of the period dealing with sacred music. Accordingly, it reconsiders the one extant passage of rhetoric to come from the Henrician regime in support of traditional church polyphony, as found in A Book of Ceremonies to be Used in the Church of England, c.1540. Examining the document's genesis, editorial history and ultimate suppression by Archbishop Thomas Cranmer, it is shown that Bishop Richard Sampson, Dean of the Chapel Royal (1522–40), was responsible for the original drafting of the musical paragraph. Beginning with Sampson's printed commentaries on the Psalms and on the Epistles of St Paul, the literary precedents and historical continuities upon which Sampson's topos in Ceremonies was founded are traced in detail. Identified through recurring patterns of scriptural and patristic citation, and understood via transhistorical shifts in the meaning of certain key words (e.g. iubilare), this new perspective clarifies important origins of the English church's musical ‘traditionalism’ on the eve of the Reformation. Moreover, it reveals a precise species of exegetical method – anagogy – as the literary vehicle through which influential clergy were able to justify expansions and elaborations of musical practice in the Western Church from the high Middle Ages to the Reformation.
