Fabrication
No full textA false etymology leads to a the word 'fabric', with its associations of weaving and knitting, practices Sadie Plant and others have descried in internet and mobile media. There is also a relevance to the archeology of visual imaging through the early use of textiles in half-tone printing, origin of the raster display nopw dominant in digital visual media. A second application takes us to the nano-scale production of chips, far too small to be made by hand, the root meaning of the alternative term 'manufacture'. An understanding of the material processes underpinning the glossy surfaces of digital audiovisual media takes us to such processes as growing crystalline lattices on CCD substrates. The third phase of the analysis takes us to the derogatory use of the term as a synonym for fiction. Digital entities are neither simulacra nor spectacle, nor in any clear sense constructions or realisms. They should be understood as fabricated in the two prior senses of weaving and of the taming of natural physical processes. This tells us how and from what digital media are fabricated, but not why. Why weave fabrications over the world? Is it to hide the destruction of the natural environment in which digital media are so deeply implicated? Is it to harness human creativity to the cycle of innovation which an increasingly systematised capitalism is no longer capable of producing itself? Or is this the most recent terrain for the centuries-old struggle between flux and order

Hemitrypus jordanianus Cope, 1876, sp. nov.
No full textHemitrypus jordanianus, Cope, sp. nov. No emargination between the anterior zygapophyses; neural spine directed upwards and backwards. The diapophyses vertically compressed, directed downwards, inwards, and backwards, and not giving origin to a strong ridge on the side of tlıe centrum, as is seen in the species of Scapherpeton. Neither is there any fossa on the side of the centrum as in that genus. There is a small longitudinal foramen which enters the inner base of the inferior half of the diapoplrysis. There is a low ridge on each side of the neural arch, which extends backwards and inwards. The anterior articular face is a wide oval somewhat contracted below, and is pierced by a foramen at a point within the superior third of the vertical diameter. It is not so deeply excavated as in the species of Scapherpeton. The posterior articular face is a regular vertical oval, is concave, but not excavated, as is seen in the centra of the genus just mentioned. The inferior face of the Centrum is rounded, with some feeble lateral ridges. [table omitted] About the size of the Menopoma allegheniense. This batrachian is dedicated to Prof. D. S. Jordan, of the Northwestern Christian University, author of the Manual of the Vertebrata of the Eastern United States.Published as part of Cope, E.

Integrity in Publishing: Some Considerations for Dealing with Complaints about Author Misconduct
No full textComplaints made to editors about an author’s unethical behaviour relating to work submitted for publication or work that has already been published must be dealt with in accordance with The Committee on Publication Ethics (COPE). Despite the ramifications of breaches of ethical practice, there is little published information about how complaints relating to author misconduct are managed. This paper provides an overview of the subject and will be of interest to authors and would-be authors
Group counseling: is it beneficial for children who are experiencing divorce cope with depression better?
No full textPlan BDivorce is increasingly disrupting the lives of millions of children each year. Children of divorced families often experience social, educational, and psychological disturbances. Numerous studies have revealed that children of divorce are significantly more depressed than children of intact families (Beer, 1989; Fendrich, Warner, & Weissman, 1990; Rotenberg, Kim, & Herman-Stahl, 1998; Simons, Lin, Gordon, Conger, & Lorenz, 1999; Zubernis, Cassidy, Gillham, Reivich & Jaycox,1999). As a result of these previous findings, it is imperative to discover ways to teach children of divorce to better cope with depression. This research project consists of a review of the literature regarding childhood depression, children of divorce, and a comparison between school-based and community-based interventions that have been used to assist children in coping with any concerns or feelings that they may be experiencing due to their parents’ divorce. The results of past research indicate that group counseling may be effective in helping children handle this difficult time in their lives. However, it appears that there is an insufficient amount of data to strongly support this claim. The purpose of this research is to propose a school-based intervention program to improve children’s coping skills whose families are experiencing divorce

Diclonius pentagonus Cope, 1876, gen. et sp. nov.
No full textDiclonius pentagonus, gen. et sp. nov. Char. Gen. - Herbivorous dinosaurians, in which the teeth are elongate and witlhout distinct root, and present dense material only on one side of the crown (the " front "), whose section produces a cutting edge. The other face of the tooth ( the " back ") is coated with cementum, and is absorbed during the protrusion of the successional tooth from below, which thus rises from "behind. " In the antero-posterior direction the teeth are protruded alternately, and the lower parts of the crowns are contracted to give space for the apices of the adjacent young teeth. In the type of the genus there is but a single series of teeth. In the known species of this genus, the denise face ("front ") of the crown presents a longitudinal keel, but this is not necessarily a generic character. The terms " front " and " back " are not intended to be accurate, as the faces so termed are either external or internal ,the direction being probably reversed in the two jaws. This genus is allied to Hadrosaurus and Cionodon. From the former it differs in the mode of succession of the teeth, which, as determined by Prof. Leidy in that genus, is from the " front " of the base of the tooth, whereas, in Diclonius, the succession is as in Cionodon, from the "posterior " base of the tooth. This arrangement allows of a more continuous use of the dense face than in Hadrosaurus, where that face terminates as the young crown rises into functional position. A species from the Fort Union bad lands of the Judith River was described by Dr. Leidy as Trachodon mirabilis. Specimens of this species from the locality furnishing those of Diclonius, present the mode of succession ascribed by that author to Hadrosaurus, to which genus he afterwards referred the species under the name of H. mirabilis. The dentition of species of this genus shows that but one tooth in mature functionial use existed in a line transverse to the axis of the jaw at one time, and that alternating with these, one partially protruded crown, and one stump of a crown, present masticating surfaces in transverse relation. The formula for this genus should then be written 2 -1, while in Cionodon it is 3 -3- 2. The type of this genus exhibits a mode of nutrition of the young teeth similar to that seen in the genus Saurocephalus among fishes. The bone is perforated by a series of foramina, each of which conveyed an artery directly into the base of the growing crown. Char. Specif. - The front of the crown is divided longitudlinally by a prominent median keel and the borders are not serrate. Thie keel is only moderately prominient at the lower part of the crown. The back of the crown is divided inito three faces by two straight longitudinal parallel solid angles, and the crown is contracted near the base by the lateral bevels for the adjacent growing teeth, All these faces are covered by cementum,whose roughness is granular in character. The external surface of the jaw-bone has precisely the same clharacter, so that the apices of the teeth only appear as prominences of its border. The typical specimen is that of an individiual of moderate dimensions; measurements of a tooth of a gigantic individual are given below.Published as part of Cope, E. D., 1876, Descriptions of some vertebrate remains from the Fort Union beds of Montana, pp. 248-261 in Proceedings of the Academy of Natural Sciences of Philadelphia 28 on pages 253-254, DOI: 10.5281/zenodo.337111
Synthesis of icariin from kaempferol through regioselective methylation and para-Claisen-Cope rearrangement
No full textThe hemisynthesis of the naturally occurring bioactive flavonoid glycoside icariin (1) has been accomplished in eleven steps with 7% overall yield from kaempferol. The 4'-OH methylation of kaempferol, the 8-prenylation of 3-O-methoxymethyl-4'-O-methyl-5-O-prenyl-7-O-benzylkaempferol (8) via para-Claisen-Cope rearrangement catalyzed by Eu(fod)(3) in the presence of NaHCO3, and the glycosylation of icaritin (3) are the key steps
