Revision and cladistic analysis of Isoctenus and description of a new neotropical genus (Araneae, Ctenidae, Cteninae)

A cladistic analysis was applied to test the monophyly of the genus Isoctenus. The data matrix comprised 28 taxa scored for 53 morphological and two behavioural characters. The analysis resulted in two equally parsimonious trees of 89 steps. The strict consensus was used to discuss the relationships of Isoctenus and related Cteninae genera. Ctenopsis Schmidt is synonymized with Isoctenus. Isoctenus foliifer Bertkau, I. strandi Mello-Leitao, I. eupalaestrus Mello-Leitao, I. janeirus (Walckenaer), I. coxalis (Pickard-Cambridge), I. corymbus Polotow, Brescovit & Pellegatti-Franco and I. malabaris Polotow, Brescovit & Ott are maintained in Isoctenus. Four species currently included in Ctenus are transferred to Isoctenus: I. griseolus (Mello-Leitao) comb. nov., I. taperae (Mello-Leitao) comb. nov., I. herteli (Mello-Leitao) comb. nov. and I. minusculus (Keyserling) comb. nov. The following specific names are synonymized: Ctenus sanguineus Walckenaer, C. semiornatus Mello-Leitao and Ctenopsis stellata Schmidt with Isoctenus janeirus (Walckenaer), Ctenus mourei Mello-Leitao with Isoctenus herteli (Mello-Leitao) and Ctenus pauper Mello-Leitao with Isoctenus strandi Mello-Leitao. Isoctenus sigma Schenkel, described from French Guiana, is transferred to Ctenus. Four species are newly described: Isoctenus areia sp. nov. from Paraiba, Brazil, I. charada sp. nov. and I. segredo sp. nov. from Parana, Brazil, and I. ordinario sp. nov. from south and south-eastern Brazil and north-eastern Argentina. Isoctenus latevittatus Caporiacco is considered species inquirenda. Parabatinga gen. nov. is proposed to include Ctenus brevipes Keyserling. The following synonymies are established: Ctenus taeniatus Keyserling, C. tatarandensis Tullgren, C. anisitsi Strand, C. atrivulvus Strand, C. mentor Strand, C. brevipes brevilabris Strand, Isoctenus masculus Mello-Leitao and Ctenus birabeni Mello-Leitao with Parabatinga brevipes (Keyserling) comb. nov.

Formgivning av magasin i ett redaktionellt utvecklingsarbete

Tidningskompaniet, a publishing agency in Göteborg, has during the spring of 2003 developed a customermagazine for Göteborgsvarvet, a Half Marathon Race in Göteborg. If realized the magazine shallbe distributed to former participants of the race twice a year and will be financed by adverts.As part of the editorial concept, development of a graphic profile will be made for the magazine. Thisdegree project will result in the production of a »dummy« magazine to be presented to the client and tobe used by the advertisement sales people in their work.The magazine, named »Varvet«, will convey the message that anyone can run Göteborgsvarvet. Theintention is to give the magazine a »youthful and sporty« image.The work in this degree project has comprised designing the magazine in co-operation with an editorialconcept developer and a project leader at Tidningskompaniet, and also the production of 18 magazinepages including prepress work. The magazine has been made into a strictly sectionized product,with a mix of short and long articles with lighter material and strict how-to-do-it guides. The designhas been made to complement the editorial concept, with typography and colours that feel modern and»active«.The dummy magazine has been digitally printed using a Xeikon digital press and has been distributedto the client and the advertisement sales bureau.

Lindex - vägen till en tydligare logotyp

Lindex has a strong fashion position and is one of northern Europe's leading fashion retailers. Unfortunately their logotype no longer measures up to the fashion level that is required. Surveys and interviews have been conducted with employees at Lindex, disscusing their logotype. I have come to the conclusion that what is needed from Lindex side is strict guidlines for the employees to follow so that all information from Lindex to their customers is made with a great touch of fashion to it and in a coherent way.

Fan Culture as an Informal Learning Environment : Presentation of a NGL project

Fan culture is a subculture that has developed explosively on the internet over the last decades. Fans are creating their own films, translations, fiction, fan art, blogs, role play and also various forms that are all based on familiar popular culture creations like TV-series, bestsellers, anime, manga stories and games. In our project, we analyze two of these subculture genres, fan fiction and scanlation. Amateurs, and sometimes professional writers, create new stories by adapting and developing existing storylines and characters from the original. In this way, a "network" of texts occurs, and writers step into an intertextual dialogue with established writers such as JK Rowling (Harry Potter) and Stephanie Meyer (Twilight). Literary reception and creation then merge into a rich reciprocal creative activity which includes comments and feedback from the participators in the community. The critical attitude of the fans regarding quality and the frustration at waiting for the official translation of manga books led to the development of scanlation, which is an amateur translation of manga distributed on the internet.  Today, young internet users get involved in conceptual discussions of intertextuality and narrative structures through fan activity. In the case of scanlation, the scanlators practice the skills and techniques of translating in an informal environment. This phenomenon of participatory culture has been observed by scholars and it is concluded that they contribute to the development of a student’s literacy and foreign language skills. Furthermore, there is no doubt that the fandom related to Japanese cultural products such as manga, anime and videogames is one of the strong motives for foreign students to start learning Japanese. This is something to take into pedagogical consideration when we develop web-based courses. Fan fiction and fan culture make it ​​possible to have an intensive transcultural dialogue between participators throughout the world and is of great interest when studying the interaction between formal and informal learning that puts the student in focus

Existential issues in surgical care : Nurses’ experiences and attitudes in caring for patients with cancer

The overall aim of this thesis was to explore surgical nurses’ experiences of being confronted with patients’ existential issues when caring for patients with cancer, and to examine whether an educational intervention may support nurses in addressing existential needs when caring for patients with cancer. Previously recorded discussions from supervision sessions with eight healthcare professionals were analysed (I), written descriptions of critical incidents were collected from 10 nurses, and interviews with open questions were conducted (II). An educational intervention on existential issues was pilot tested and is presented in Studies III and IV. The intervention was the basis of a pilot study with the purpose of testing whether the whole design of the educational intervention, including measurements instruments, is appropriate. In Study III and IV interviews with 11 nurses were conducted and 42 nurses were included in the quantitative measurements of four questionnaires, which were distributed and collected. Data was analysed using qualitative secondary analysis (I), hermeneutical analysis (II), and mixed methods using qualitative content analysis and statistical analyses (III-IV). Results in all studies show that existential issues are part of caring at surgical wards. However, although the nurses were aware of them, they found it difficult to acknowledge these issues owing to for example insecurity (I-III), a strict medical focus (II) and/or lacking strategies (I-III) for communicating on these issues. Modest results from the pilot study are reported and suggest beneficial influences of a support in communication on existential issues (III). The results indicate that the educational intervention may enhance nurses’ understanding for the patient’s situation (IV), help them deal with own insecurity and powerlessness in communication (III), and increase the value of caring for severely ill and dying patients (III) in addition to reducing work-related stress (IV). An outcome of all the studies in this thesis was that surgical nurses consider it crucial to have time and opportunity to reflect on caring situations together with colleagues. In addition, descriptions in Studies III and IV show the value of relating reflection to a theory or philosophy in order for attitudes to be brought to awareness and for new strategies to be developed.

Kritisk diskursanalys av Gy2011 med fokus på kulturkontexten : Politiska diskursers relation till svensk läroplansutveckling

This research aims to relate the modern Swedish curriculum development to the political discourses liberalization and European integration through a critical discourse analysis of the Swedish curriculum Gy2011. These political discourses constitute the cultural context of Gy2011, which according to critical discourse theory is synonymous with the terms social sphere or praxis. The term cultural context includes the environment in which the text has been created as well as its intertextuality – in this case its relations to earlier curricula. The analysis of Gy2011 exhumes scientific research done in the field of curriculum studies, which enables future research. The Gy2011 analysis shows that the political discourses liberalization and European integration stands out within the texts cultural context, and have done so for more than 70 years, a fact that is illustrated by an overview of Swedish curricula history. This research also illuminates how the liberalization discourse accelerated during the 1980’s, by both social democrats and the political right, and that the European integration process has gained momentum in recent years.

Estudio intertextual en dos cuentos de Borges : Pierre Menard, autor del Quijote y La biblioteca de Babel

This studyfocuses on the theory of intertextuality and on the most important approachesof Julia Kristeva, Gerard Genette and Ronald Barthestothis theory. It also examines the intertextual relationships in twoworksof Jorge Luis Borges:Pierre Menard, author of the Quixoteand The library of Babel. This studyconcludes that intertextual relations and issues are very often used in the works of Jorge Luis Borges. Analysis of histwoworks has shown the most obvious indicators of intertextuality such as allusions, quotations and references.

Conceptualizing Wilderness Through GIS

The word “wilderness” in America is generally identified with pristine places where humans are not among the primary influences on the land and its ecology. The American wilderness ethic creates a strict dichotomy between humans and nature. The Wilderness Preservation Act of 1964 defines wilderness as “an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain” (wilderness.net). This statutory definition of wilderness is essentially the functional embodiment of the American wilderness ethic. Wilderness can also be interpreted in ways that incorporate humans as active players in the natural world. Land which is managed for human use but is uninhabited can be considered wilderness to some degree because “man himself is a visitor who does not remain.” Wilderness, especially in the Northeast, can be visualized based on different land use characteristics. Conservation in the Northeast requires a redefinition of wilderness in order to incorporate land that has been utilized by humans.

Social Media, Privacy, and the Academic Classroom

We live in a world full of social media and portable technology that allows for the effortless access to, and sharing of, information. While this constant connection can be viewed as a benefit by some, there have been recent, sometimes embarrassing, instances throughout the world that show just how quickly any expectation of privacy can be destroyed. From pictures of poorly dressed shoppers at a grocery store to customers recording interactions with their servers at restaurants, the internet is full of media (all with the potential to go viral) created and posted without consent of all parties captured. This risk to privacy is not just limited to retail and restaurants, as being in any situation amongst people puts you at risk, including being in an academic classroom. Anyone providing in-class instruction, be they professor or librarian, can be at risk for this type of violation of privacy. In addition, the students in the class are also at risk for being unwittingly captured by their classmates. To combat this, colleges and universities are providing recommendations to faculty regarding this issue, such as including suggested syllabus statements about classroom recording by students. In some instances, colleges and universities have instituted formal policies with strict penalties for violators. An overview of current privacy law as it relates to an academic setting is discussed as well as recent, newsworthy instances of student recording in the classroom and the resulting controversies. Additionally, there is a discussion highlighting various recommendations and formal policies that have been issued and adopted by colleges and universities around the country. Finally, advice is offered about what librarians can do to educate students, faculty, and staff about the privacy rights of others and the potential harm that could come from posting to social media and the open web images and video of others without their consent.

Extrativismo em área de reserva da biosfera da Mata Atlântica no Rio Grande do Sul : um estudo etnobiológico em Maquiné

As frondes de Rumohra adiantiformis (G.Forest.) Ching, conhecida como “leatherleaf”, “seven-weeks-fern” ou samambaia-preta, são usadas mundialmente em arranjos florais. Na África do Sul e Brasil o comércio da espécie é baseado no extrativismo. No Brasil a coleta é realizada em áreas de Mata Atlântica, sendo que 50% da produção provém das áreas de capoeira das encostas da Serra Geral no Rio Grande do Sul (RS). Atualmente, cerca de 2.000 famílias de agricultores familiares vivem nestas áreas, tendo no extrativismo sua principal fonte de renda. No entanto no RS a coleta, o comércio e o transporte de plantas ornamentais nativas são proibidos, já que nesta zona de transição da Reserva da Biosfera da Mata Atlântica (Maquiné, RS) há grandes restrições quanto à exploração dos recursos naturais. O êxodo rural e o próprio extrativismo estabelecido a partir da década de 70, permitiram a regeneração da Floresta Ombrófila Densa. Como a espécie é característica de estágios sucessionais iniciais, a regeneração florestal está levando à diminuição dos estoques naturais. Este trabalho se propôs a identificar alternativas econômicas para diversificação da economia de famílias de extrativistas, no intuito de minimizar a tensão associada à diminuição dos estoques naturais de samambaia-preta, às dificuldades no manejo da terra e à legislação ambiental. Junto à comunidade extrativista do distrito de Solidão (Maquiné) foram coletados dados etnobiológicos sobre plantas medicinais e plantas relacionadas ao artesanato. As principais espécies identificadas foram: Bambusa tuldoides (taquareira, colmo), Clytostoma sciuripabulum (cipó-branco, caule), Cyperus prolixus (tiririca, partes aéreas), Musa acuminata (bananeira, palha), Scirpus californicus (junco, partes aéreas), Typha dominguensis (taboa, partes aéreas), sendo que Macfadyena dentata (cipó-unha-de-gato, caule), Roupala brasiliensis (carvalho-brasileiro, folhas) e Tillandsia usneoides (barbade- pau, planta inteira) são as espécies prioritárias para a avaliação da sustentabilidade do extrativismo. Os dados etnobiológicos e ecológicos mostram que é possível estabelecer o manejo sustentável da R. adiantiformis. Os maiores entraves para o estabelecimento do manejo sustentado para as espécies identificadas incluem: a) estabelecer as bases de manejo sustentável destas espécies; b) compatibilizar esta atividade extrativista com o atual Código Florestal Estadual. Plantas medicinais não parecem ser uma alternativa viável a curto prazo, enquanto o artesanato requer a adequação da atividade artesanal no meio rural com os direitos à aposentadoria rural.

Homothetic preferences

This paper describes properties of upper semi-continuous homothetic preferences. First we give conditions for the existence of an upper semi-continuous representation which is homogeneous of degree one. Then we show that with the additional assumptions of monotonicity or strict convexity, the preference is continuous. Several counterexamples illustrate the tightness of the results.

A family of autoregressive conditional duration models

This paper develops a family of autoregressive conditional duration (ACD) models that encompasses most specifications in the literature. The nesting relies on a Box-Cox transformation with shape parameter λ to the conditional duration process and a possibly asymmetric shocks impact curve. We establish conditions for the existence of higher-order moments, strict stationarity, geometric ergodicity and β-mixing property with exponential decay. We next derive moment recursion relations and the autocovariance function of the power λ of the duration process. Finally, we assess the practical usefulness of our family of ACD models using NYSE transactions data, with special attention to IBM price durations. The results warrant the extra flexibility provided either by the Box-Cox transformation or by the asymmetric response to shocks.

Inflation and debt indexation : the equivalence of two alternative schemes for the case of periodic payments

The presence of inflation has induced the financial institutions to implement procedures devised to protect the real values of theirs loans. Two of such procedurcs, the floaaing rale scheme and the monetary correction mechanism, tend to lead to very different streams of payments. However, whenever the floating rate scheme follows the rule of Strict adhercnce to lhe Fisher equation, lhe two procedures are financially equivalent.
