4. Snakes

The roughly 3,500 species of snakes are really a group of limbless lizards, although they are so distinctive, with so many unique features, that they are placed in their own reptile subclass, Ophidia or Serpentes. They have a worldwide distribution, occupying habitats from deserts to rainforests and seas. ‘Snakes’ describes how snakes feed, move, and make sense of their surroundings, as well as their social and reproductive behaviour. The main aspect of snake biology that accounts for their great success as hunting organisms is the way they acquire and ingest their food. The rear-fanged (colubrids) and front-fanged groups (elapids and viperids) are described along with their venom production.

To speak of Brahms and Beethoven in the same breath is almost a cliché: Brahms was intimately conscious of Beethoven's music from early youth. This article describes the details of his youthful involvement, the compositions he had in his repertoire as well as those other works which had a powerful effect on his development. By age 20, Brahms was frequently compared to Beethoven by people who met him or heard him play. My interest is in the way he was influenced by Beethoven and the manner in which he eventually found his own voice. The compositional history of his First Symphony provides the primary focus: its long gestation, and the alleged quote by Brahms given in Max Kalbeck's massive biography: ‘I'll never write a symphony, you have no idea what it feels like … to hear the footsteps of a giant behind one’. The reference is presumably to Beethoven, but there exists no corroborating evidence that Brahms ever said those words. They gained credence as one writer after another simply accepted Kalbeck's word. Yet substantial evidence exists that in writing his biography, Kalbeck distorted and even invented ‘facts’ when it suited his purposes, including a specific instance dealing with writing a symphony. An alternative view of the symphony's long gestation is based on a view of Brahms's compositional history. He wrote for musical forces he knew at first hand, and only from 1872 to 1875 did he have command of an orchestra. Intriguingly, while fulfilling the contemporary accepted demands of a symphony after Beethoven, Brahms devised an unusual strategy for the final movement, the basis of its great success.

Abstract Background and study aims In the last decade, gastroenterologists have been attempting to use endoscopy to reproduce the great success of traditional surgical suture techniques. Despite recent advances, we still lack a reliable method that results in a permanent suture with minimal incidence of suture failure. This was an experimental study in pigs with an innovative technique that applied basic surgical concepts to endoscopy to evaluate the effectiveness of a novel suture technique. Methods The procedures were performed on six live pigs under general anesthesia. Endoscopic mucosal resection (EMR) first was performed in the stomach, exposing the submucosal or muscularis propria layers. A novel device, a transparent chamber cap (DASE), was developed to aspirate the gastric wall, allowing the sutures to reach deep layers. The aspiration was performed with a standard gastroscope to which the novel cap was distally attached. Three sutures aligned were defined as a plication. Each pig received two or three plications and was placed on a liquid diet for 14 days after the procedure. The pigs were sacrificed at 4 and 8 weeks and the sutures were reviewed. Results The technique was feasible in all animals. Of 16 plications, only one failed. One perforation occurred after EMR. There were no other complications or adverse events. Permanent fusion of the gastric wall was confirmed by histology in all cases. Conclusions This study showed that basic principles of surgery can be applied endoscopically to ensure a permanent suture with reduced chances of failure. These findings can help to pave the way for more effective bariatric endoscopic techniques.

Songwriter Cole Porter is unusual in having had two biopics based on his life: Night and Day (1946) starring Cary Grant, and De-Lovely (2004), starring Kevin Kline. The differences in the treatment of the character of Cole Porter between the films are striking, and indicate a change in the way that society envisions its artists, and the very act of creativity. Night and Day was conceived partly as a showcase of Porter's songs, but also as a means of providing inspiration to soldiers returning wounded from World War II, based on Porter's recovery from a traumatic riding accident. It depicts Porter as an everyman following a trajectory of achievement, from having little to great success, which was positioned as easy to emulate. De-Lovely, on the other hand, is about the relationship between Porter and his wife Linda, and the way that his creativity was influenced by his changing relationships with various people. Drawing on the work on biopics of scholars such as G.F.Custen, together with research into the shifting ideas of how creativity operates and is popularly understood, this article uses these biopics as case studies to examine the representation of changing concepts of the artist and the act of creativity through Hollywood film. It also considers how these changing conceptions and representations connect to shifts in American society.

This article explores marital fertility on the Aegean island of Paros based on family-reconstitution data from one main town and one village on the island, namely Naoussa and Kostos. By probing the reproductive behaviour of couples who married between 1894 and 1953 it was found that fertility was still ‘natural’ on the island at the beginning of the twentieth century, while a substantial fertility decline made itself visible only in the late 1920s and early 1930s. The way the population switched from natural to controlled fertility is also explored, as well as the contribution of different socio-economic groups to fertility transition. In the end, an effort is made to place the examined population in a wider European and national context.

Religion is the main aspect in constructing a discourse because the Javanese society in the 18th are thickly related with religiosity (Islam) as an inherited principle from the previous king. Mangkunegara I is an influential and interesting figure in the history of Javanese leadership relating to Islam. The medium used in the Islamization process by Mangkunegara I are through art, culture, customs and Islamic religious education. This study aims to show the Javanese Islamic discourse during the leadership of Mangkunegara I in the Babad Kemalon (Pakunegara)/ BK manuscript. The BK manuscript is a Javanese manuscript contains of 30 macapat songs which tells about the struggle of R.M. Said until entitled Mangkunegara I. this research uses the cultural studies paradigm. The theory used is the discourse theory proposed by Michael Foucault. The method used is a qualitative method and the data analysis techniques are done descriptively and interpretatively. This research belongs to library research. The result shows how the leadership of Mangkunegara I was able to show its discourse in Javanese Islam, which was manifested by the way of Mangkunegara I leaderships towards himself, his families, and people. As well as the Islamic base struggle which is always emphasized by Mangkunegara I.

Originally emerging from the field of EU studies, the notion and approach of multi-level governance (MLG) have progressively been transferred to a variety of other subfields. This chapter argues that three particularities characterize the way in which French political scientists have dealt with governance and MLG. First, the notion of governance has not had great success since the existing notion of government has long been used in a sociological and relational way to describe processes and outcomes rather than merely executive institutions. Second, French scholars who adopted the notion quickly departed from the early definition of governance as opposed to government, institutions, or coercion. Third, the use of governance and MLG helped to consolidate a French way of doing political science that was based on a reluctance toward theoretical hastiness, a sensitivity to varieties of situations and processes in time and space, and a shared constructivist stance.

A mathematics specialist has great success using a pattern-block configuration to help a small group of fifth graders understand that fractional parts of a whole unit must be equal in size. That's just the way the funky cookie crumbles.

AbstractThe problem of extended fusion and identification can be approached from a diachronic perspective. Based on our own research, as well as findings from the fields of social, political, and clinical psychology, we argue that the way contemporary emotional events shape local fusion is similar to the way in which historical experiences shape extended fusion. We propose a reciprocal process in which historical events shape contemporary identities, whereas contemporary identities shape interpretations of past traumas.

Abstract The purpose of human cognition depends on the problem people try to solve. Defining the purpose is difficult, because people seem capable of representing problems in an infinite number of ways. The way in which the function of cognition develops needs to be central to our theories.

Ap stars are peculiar in many aspects. During this century astronomers have been trying to collect data about these and have found a confusing variety of peculiar behaviour even from star to star that Struve stated in 1942 that at least we know that these phenomena are not supernatural. A real push to start deeper theoretical work on Ap stars was given by an additional observational evidence, namely the discovery of magnetic fields on these stars by Babcock (1947). This originated the concept that magnetic fields are the cause for spectroscopic and photometric peculiarities. Great leaps for the astronomical mankind were the Oblique Rotator model by Stibbs (1950) and Deutsch (1954), which by the way provided mathematical tools for the later handling pulsar geometries, anti the discovery of phase coincidence of the extrema of magnetic field, spectrum and photometric variations (e.g. Jarzebowski, 1960).
