Nove espécies compõem o grupo "cuvieri" e dessas apenas P. cuvieri já teve seu cariótipo descrito com detalhes, tendo apresentado expressiva variação intra e interpopulacional em relação à localização de regiões organizadoras de nucléolo (NOR). Dado que P. Cuvieri apresenta ampla distribuição geográfica e que a variação mencionada foi encontrada em populações do sul e do sudeste do Brasil, no presente trabalho ampliamos seu estudo, com a análise cromossômica de quatro populações da região nordeste, uma da região norte e uma da região sudeste do Brasil. Adicionalmente uma população da Argentina também foi estudada. Com o intuito de comparar cariotipicamente P. cuvieri com outras espécies de Physalaemus, também foram estudados os cariótipos de P. albonotatus, P. centralis, P. cuqui e P. ephippifer, pertencentes ao grupo "cuvieri", P. albifrons, espécie recentemente removida desse grupo, e P. santafecinus atualmente do grupo de P. albifrons. Todas as populações de P. cuvieri aqui estudadas apresentaram cariótipo com 2n=22 cromossomos e grande variação em relação às NORs pôde ser observada. Duas populações de P. cuvieri (Urbano Santos-MA e Crateús-CE) apresentaram as NORs nos pares 8 e 9. No par 8, a NOR, de localização intersticial, mostrou-se adjacente a uma região de heterocromatina, enquanto a NOR presente no par 9 foi coincidente com um bloco heterocromático. Na população de São Pedro da Água Branca (MA), além dos pares 8 e 9, o par 7 foi também portador de NOR. Na população de Palmeiras (BA) e Uberlândia (MG), apenas um par cromossômico (8) foi portador de NOR. Na população mineira, diferenças intra-individuais foram encontradas principalmente em relação ao tamanho da NOR. Já nas populações da Argentina, a NOR intersticialmente localizada no o par cromossômico 8 não foi encontrada. Em todos os exemplares dessas populações argentinas, o par 11 foi portador de NOR e NORs adicionais foram encontradas nos cromossomos 1, 7 ou 8 (em posição pericentromérica) em alguns indivíduos. É interessante notar que o morfo 11 dessa população argentina é muito semelhante ao cromossomo 11 encontrado na população de Santa Maria (RS) analisada anteriormente. Já na população do estado de Tocantins, NORs múltiplas foram visualizadas em pelo menos cinco cromossomos (pertencentes aos pares 1, 3, 4 e 10), padrão que difere bastante daqueles encontrados nas outras populações de P. cuvieri. Também em relação ao padrão de distribuição de bandas heterocromáticas no cariótipo, a população de Tocantins analisada difere das demais, fato que intriga e corrobora a necessidade de uma revisão taxonômica da espécie em questão. A morfologia cariotípica de P. albifrons, P. albonotatus, P. centralis, P. cuqui, P. ephippifer e P. santafecinus foi muito semelhante, principalmente em relação aos primeiros pares cromossômicos, embora em P. albonotatus e P. cuqui a ordenação de alguns pares tenha sido diferente. Todas essas espécies puderam ser diferenciadas pela localização da NOR e em P.ephippifer um interessante heteromorfismo foi observado no par 8 portador de NOR em todas as fêmeas analisadas. Não foi descartada a hipótese de tal heteromorfismo estar relacionado à determinação sexual nessa espécie, no entanto, futuros estudos são necessários para sua comprovação. Exceto no cariótipo dos indivíduos de P. cuvieri de Tocantins, nos cariótipos aqui descritos a principal (ou única) NOR foi encontrada nos últimos pares cromossômicos, alterando a morfologia desses, o que dificultou a inferência de homeologias interespecíficas e dos possíveis rearranjos que envolveram a NOR durante a diferenciação das espécies em análise. Já com o bandamento C, algumas homeologias interespecíficas foram claramente notadas. Uma banda intersticial no braço curto do par 5, outras na região pericentromérica do braço curto dos pares 3 e 7, por exemplo, foram encontradas em P. cuvieri, P. centralis e P. ephippifer, e parecem homeólogas às encontradas nos pares classificados como 3, 5 e 7 no cariótipo de P. albonotatus / Abstract: The genus Physalaemus is composed by 41 species distributed in seven groups: ¿albifrons¿, ¿cuvieri¿, ¿deimaticus¿, ¿gracilis¿, ¿henselii¿, ¿olfersii¿ and ¿signifer¿. Nine species compose the group ¿cuvieri¿ but just P. cuvieri had already been karyotyped in details. Expressive intra and interpopulational variation related to the localization of the nucleolus organizer regions (NOR) was described for this species. Physalaemus cuvieri is widely geographically distributed and NOR variation was described based on populations from Southern and Southeastern Brazil. In the present work we analyzed the cytogenetic of four populations from Northeastern, one from Northern and one from Southeastern Brazil. Additionally, three Argentinian populations were also included. To cytogenetically compare P. cuvieri with other species of Physalaemus, species belonging to P. cuvieri group (i.e. P. albonotatus, P. centralis, P. cuqui and P. ephippifer), P. albifrons, recently removed from this group, and P. santafecinus, currently alocated in P. albifrons group, were also analyzed. All populations of P. cuvieri studied here showed diploid number of 22 chromosomes and high intraspecific variation was observed related to the NORs. Two populations of P. cuvieri (Urbano Santos, state of Maranhão (MA) and Crateús, state of Ceará (CE)) had pairs 8 and 9 as NOR-bearing chromosomes. In pair 8 the interstitial NOR was adjacent to C-bands whereas the NOR at the nineth pair was coincident with a heterochromatic block. In the population from São Pedro da Água Branca, state of Maranhão (MA), besides pairs 8 and 9, the seventh pair was also a NOR-bearing one. The specimens from Palmeiras, state of Bahia (BA) and Uberlândia, state of Minas Gerais (MG) showed only one NOR, which was located at pair 8. In the population from Uberlândia (MG) intraindividual differences was found related to the NOR size. In the populations from Argentina, the interstitial NOR in chromosome pair 8 was not found. In all the specimens of these Argentinean populations, pair 11 was the NOR-bearing chromosome pair and additional NORs were also found in chromosomes 1, 7 or 8 (in a pericentromeric position) in some of the individuals. The morph 11 of specimens from Argentina was very similar to the NOR-bearing eleventh pair described for specimens from Santa Maria (RS) previously analyzed. In contrast, in the population from Porto Nacional, state of Tocantins (TO), multiple NORs were visualized at least at five chromosomes (belonging to pair 1, 3, 4 and 10), a pattern that greatly differed from those found in the others populations of P. cuvieri. Also concerning the C-band distribution, the karyotype found in the population of Tocantins differed from the others. These findings are very interesting and can be useful for future taxonomic studies of this taxon. Regarding to chromosome morphology, P. albifrons, P. albonotatus, P. centralis, P. cuqui, P. ephippifer and P. santafecinus were very similar, specially for the seven first chromosome pairs, although in P. albonotatus and P. cuqui the position of some chromosome pairs was different. All the species could be differentiated by NOR localization and in P. ephippifer an interesting heteromorphism was detected in NOR bearing pair 8 of all the females. We do not discard the hypothesis that such heteromorphism could be related to sex determination in this species, but future studies are necessary to test it. Except for the karyotype of P. cuvieri from Tocantins, the karyotypes described here the principal (or only) NOR was found among the last chromosome pairs, resulting in different chromosome morphologies, what impaired interespecific inferences of homeologies and the recognition of possible rearrengements involving the NOR during the differentiation of the species analyzed. On the other hand, C-banding tecnique permitted to notice some interspecific homeologies. A band at an interstitial region in the short arm of pair 5, and pericentromeric C-bands in the short arm of pairs 3 and 7 were detected in P. cuvieri, P. centralis and P. ephippifer which seemed to be homeologous to C-bands found in pair 3, 5 and 7 of P. albonotatus / Mestrado / Biologia Celular / Mestre em Biologia Celular e Estrutural

Parte-se dos referenciais da Teoria dos Modelos Organizadores do Pensamento, do Paradigma da Complexidade e de perspectivas críticas sobre os estudos de gênero como contribuintes de aspectos conceituais e metodológicos na análise do funcionamento psíquico. Foram levantadas informações com 400 jovens (15 a 21 anos), de escolas públicas e particulares, em dois estados do Brasil (Mato Grosso e São Paulo). Solicitou-se que respondessem por escrito a quatro questões sobre os sentimentos, pensamentos e o dever das personagens (meninos ou meninas) diante de uma situação (sofrida ou presenciada) de discriminação de gênero e sexual (homofobia) na escola. Analisamos a perspectiva de gênero na resolução do conflito a partir do sexo das personagens, considerando as variáveis sexo dos participantes e estado brasileiro de origem. Os resultados mostram que as representações de gênero têm papel relevante no modo como os jovens e as jovens resolvem conflitos interpessoais, marcando a produção de estereótipos nas relações sociais entre homens e entre mulheres na escola / Abstract: This research aimed at investigating the organizer models about gender representations in interactive conflicts resolution in educational context. It is based on the Organizer Models Theory, the Complexity Paradigm, and the critical perspectives about gender studies as conceptual and methodological tools in psychic processes analysis. We conducted the information collection with 400 young people, aged from 15 to 21 years-old, from public and private schools, in two Brazilian states (Mato Grosso and São Paulo). We asked them to answer, by writing, four questions about a situation feelings, thoughts at the duty of the characters (boys and girls) in relation to the situation (suffered or viewed) of gender and sexual discrimination (homophobia) in school. We analyzed the gender perspective on the conflict resolution based on the characters sex, considering the participants sex and the Brazilian states. The results showed that the gender representations have a relevant role in the way the young people solve interactive conflicts by marking the stereotype production in social relationship between men and women in school / Doutorado / Ensino, Avaliação e Formação de Professores / Doutor em Educação

Students with emotional behavioral disorders (EBD) who have been removed from their regular schools into alternative educational settings (AES) have academic deficits that affect their success in school (Lehr, Tan, & Ysseldyke, 2009); however, few researchers have investigated what strategies work best for this population, especially in the area of math (Schwab, Johnson, Ansley, Houchins, & Varjas, 2016). Two important areas that students with EBD must master to graduate high school are fractions and algebra (Templeton, Neel, & Blood, 2008). Since the research on math interventions for students with EBD in these areas is limited, researchers have suggested examining the math literature for students with learning disabilities (LD) to find potential intervention components. The purpose of the first study was to synthesize the randomized control trials and quasi-experimental intervention research on instructional approaches that enhance the math achievement of students in grades 6-12 with LD. This study used meta-analytic techniques to synthesize the math literature for secondary students with LD. Findings indicated that strategy instruction had a higher effect size (Hedges g= .72) than alternate delivery systems (Hedges g= .23), and the number of Common Core State Standard math practices was a moderator for the effect size of math interventions. Since strategy instruction had a higher effect size, the purpose of the second study was to test the effects of a graphic organizer on the math performance for middle school students with EBD in an AES. This study used a one-group nonequivalent dependent variables design (Shadish, Cook, & Campbell, 2002) with multiple measures in multiple waves to assess the effects of the graphic organizer on the math skills of the students. A repeated measures ANOVA indicated that students significantly improved their math performance on both fractions and algebra using researcher developed measures. Fidelity data indicated that two teachers had low adherence, quality of instruction scores and had low percentages of student engagement. Social validity results indicated that teacher and students found the intervention to be an acceptable intervention.

The thesis entitled "Legal aspects of organizing music events" deals with musical performances from the perspective of organizers, performers, but also the wider public. The aim is to identify the legal issues that must be seen to by the organizer of musical performances and to evaluate the operation and use of the services of collective rights management societies and to evaluate the impact of copyright infringement and attitude of the society to its violation. The introductory chapter provides an overview of the legislation and discusses copyright and certain organizations that work in this field. The second chapter describes the activities of collective rights management companies. Equally important is the third chapter, which deals with license agreements and the different types of licenses. The final chapter applies the theoretical knowledge gained from previous chapters into practice.

Le développement embryonnaire est un processus hautement contrôlé où différentes voies de signalisation se coordonnent pour la construction d'un organisme. L'une des principales voies de signalisation impliquées dans ce processus est la voie canonique Wnt. La longue quête pour comprendre la cascade de signalisation Wnt/β-catenine a révélé que la réponse transcriptionelle induite par le signal Wnt/β-catenine est dépendante du contexte, ou compétence, cellulaire. Peu de choses sont connues sur les évènements moléculaires qui influencent cette compétence cellulaire. Dans les embryons de X. laevis Wnt/β-catenine est le signal inducteur pour l'Organisateur de Spemann. On ne sait pas ce qui limite l'activité Wnt dans ce territoire et par voie de conséquence la taille de l'Organisateur. Les résultats présentés dans ce manuscrit de thèse montrent que le facteur de transcription Barhl2 affecte le développement de l'organisateur de Spemann. Nous démontrons que Barhl2 inhibe l'activité Wnt via son interaction avec le corépresseur Groucho et le facteur de transcription Tcf, et mobilise l'activité de Hdac1 qui agit sur la structure chromatinienne. En utilisant des expériences in vitro et in vivo sur des cellules en culture et des embryons de Xénope nous démontrons que la régulation de Barhl2 sur les activités Groucho-Tcf est maintenue pendant l'embryogenèse et joue un rôle dans le confinement des progéniteurs neuraux dans le cerveau. Ensemble, nos résultats fournissent un mécanisme nouveau et important agissant sur le contrôle de l'activité transcriptionelle Wnt et la compétence des cellules à répondre à ce signal. / Embryonic development is a highly controlled process where different signaling pathways participate into the elaboration of an organism. One of the main signaling pathways is the Wnt canonical pathway. The long-lasting search to understand Wnt/β-catenin transduction cascade revealed that the net transcriptional read out of Wnt/β-catenin signaling is highly dependent on the cellular context. In X. laevis embryos Wnt/β-catenin signaling is the informative signal for the Spemann Organizer induction. However little is known on what limits Wnt activity in this territory and consequently the size of the Spemann Organizer. The results presented in this manuscript provide evidence that the evolutionarily conserved transcription factor Barhl2 limits the development of the Spemann organizer. In this territory Barhl2 inhibits Wnt activity via its interaction with the co-repressor Groucho and the transcription factor Tcf. It participates to the recruitment of the chromatin remodeling enzyme, Hdac1 that represses the expression of Spemann organizer genes. Using a Xenopus tropicalis Tcf reporter line we demonstrate that Barhl2 inhibitory effect on Groucho-Tcf activities is maintained during embryogenesis and plays a role in the confinement of neural progenitors in the brain. Together, our results provide a new and important mechanism for the control of Wnt transcriptional activity.

In this work I focused on the possibility to develop LARP in the means of participation and performance. Furthermore, I focus on the continuity of individual games (segments) and the possibility of connecting various, already existing, LARP genres. In this series of games, the most striking of the genres is the political LARP, whose political charge has been intermingled by other LARP genres in my work.

In this networked society, where social media becomes a natural meeting place, the need for physical encounters is greater than ever. In the business world, business events are a way for people to satisfy this need while they at the same time get the opportunity to exchange skills, information and experiences with other colleagues, thus expanding their and their company’s competencies. This report looks at how business events are distributed today and investigates the interest for a new channel where business events are collected which is of mutual value for business event organizers and attendees. In order to understand the needs of event organizers and attendees a survey has been conducted consisting of a questionnaire, interviews and a focus group, which helped pinpoint three relevant themes: discover, organize and connect. The themes were based on wishes left by the respondents, declaring that finding information about events were a difficult and time consuming procedure. They wanted an easier way to find interesting events and sorting out those that were of relevance to their jobs and surrounding areas. Similarly the organizers had noticed an increasingly competitive market making it difficult to reach customers. It was also observed by the organizers that people go to events to network, leading to the conclusion that one element of the service should be about connecting with colleagues, possible business partners and other interesting people. As a result, a design proposal was presented in the form of a mockup of a mobile application interface where the themes were present as sections of a quick access menu. To conclude, the report discusses suggestions on how to proceed with the design proposal and makes recommendations on future research on the development of an app for business events. / I ett samhälle som präglas av nätverkande och där sociala medier blivit en naturlig mötesplats, är behovet av fysiska möten större än någonsin. Företagsevent är ett sätt att fylla det behovet, samtidigt som man får möjlighet att utbyta kunskaper, information och erfarenheter med andra kollegor för att utveckla sin kompetens och därmed bli en större tillgång till företaget. Denna rapport tittar på hur företagsevent distribueras idag och undersöker intresset för en ny digital kanal som samlar aktuella företagsevent och som är av gemensamma intressen för företagare och kunder. För att förstå organisatörernas och användarnas behov har en undersökning genomförts bestående av en enkät, intervjuer och en fokusgrupp. Resultatet av undersökningen visar på tre relevanta teman, upptäck (discover), organisera (organize) och nätverka (connect), som skulle fungera som stöttepelare för en ny kanal. Dessa teman har framkommit i och med att de tillfrågade ansåg att det var svårt och tidskrävande att leta upp information om nya företagsevent. De ville ha ett enklare sätt att upptäcka intressanta event och möjligheten att sortera ut de event som var relevanta i relation till yrkesområden och intressen. Samtidigt har eventarrangörerna märkt av en allt tuffare konkurrens på marknaden som gör det svårt att nå kunder. Observationen att nätverkande är en stor faktor när det kommer till varför man deltar i företagsevent ledde till slutsatsen att en del av tjänsten ska tillåta kontaktutbyte med kollegor och andra intressanta personer. Slutligen presenteras ett konceptuellt designförslag i form av en mockup av en mobilapplikation där nämnda teman implementeras i varsina delar i en snabbåtkomstsmeny. Avslutningsvis diskuteras förslag på hur man kan gå vidare med designförslaget samt rekommendationer om fortsatt utveckling av en tjänst för företagsevent.

近年來由於會議展覽服務業的興起，所以一些具有商業意義的展覽相關議題亦逐漸被重視，然而過去的研究多著重在探討商展買賣雙方（參展者、參觀者）的關係，甚少以策展單位的角度切入，來完整觀察整個展覽之規劃、營運、執行、以及其在產業上所扮演的角色。此外，由於展覽不僅只是一個單純的交易平台，更是產業上商機、資源、資訊匯集交流的場所，以及創新概念、技術、產品的擴散地，此猶如扮演著產業上的「守門」角色一般。 因此，本研究便藉由產業的「守門機制」理論來從新檢視展覽，透過以資訊電子產業中具有極重要地位和完整發展、消長歷史的世界三大電腦展COMDEX Fall、CeBIT、COMPUTEX Taipei為個案，進而發現、瞭解展覽的策展單位如何在展覽前期將自己定位，透過劃定邊界、篩選遞送內容來扮演好守門機制的功能與角色，並配合自身的守門能耐，進一步地影響到展覽活動內容的呈現，使其能夠在不同的活動內容中扮演不同類型的守門機制，以及最終其在守門成果對於產業上創新概念、技術、產品的影響為何，並且是否會因而影響參展者與參觀者的參與意願。 本研究所得的研究結論如下。 1、展覽中的各項活動內容（展覽會、會議、獎項）在商品化的過程中，藉由策展單位「劃定邊界」、「篩選內容」守門機制之執行，各自扮演著產業守門機制的不同角色。 →展覽活動內容的「展覽會」，屬於守門類型中，策展單位會對於參展、參 觀者來加以設定、限制，並從展覽會現場中持續地篩選遞送全面性、系統性資訊內容的「創新型守門機制」。 →展覽活動內容的「會議」，包含了「主題演講」、「論壇、研討會」、「產品發表會」三種類型的活動。其中「主題演講」和「產品發表會」，屬於守門類型中，策展單位不會對參與群眾加以限制，並且從活動中傳播較為區段性資訊內容的「資訊型守門機制」。而「論壇、研討會」則屬於策展單位會對參與群眾加以設定、限制，並從中遞送區段性資訊內容的「典範型守門機制」。 →展覽活動內容的「獎項」，屬於守門類型中，策展單位需對參賽者加以設定、限制、評選，而且從獎項的頒佈、宣傳向其相關廠商和大眾產生示範、鼓勵的作用，進而遞送出區段性資訊內容的「典範型守門機制」。 2、策展單位守門機制之執行會與守門能耐之間彼此相互影響，並且在策展單位執行守門機制時，策展單位的守門能耐會有時序上的順序展現。 3、策展單位守門機制的運作與執行，會受到策展單位不同的組織類型所影響。 4、策展單位的守門能耐會受到策展單位組織的類型、資源、網路所影響。 5、展覽守門成果在創新概念、創新技術、創新產品的傳播、擴散上，會受到展覽的產業守門機制所影響。若是策展單位在展覽的產業守門機制上沒操作執行好，將會使得展覽守門成果的代表性和創新性不足、參展成效不彰，進而影響參展者和參觀者的參與意願，最終將會導致展覽的衰亡。 6、展覽本身的守門成果會深受其展覽舉辦所屬產業發展的影響，進而會影響到展覽產業守門機制的展現。 / Recent years, with the growth of the M.I.C.E industry, some subjects about commercial exhibitions have also been attached importance to. However, the researches in the past almost emphasize on the relation between exhibitors and visitors in the trade shows, and there are few researches which is from the organizer perspective to obverse the plans, operation, administration, and the special roles in the industry of the exhibition. Besides, the exhibition is not only just a trade platform, but also a place in which people can collect and exchange business opportunities, resources, information of the industry. It is also a diffuse place of innovative concepts, technology, and products in the industry. Above all, the exhibition is just as the role of the industrial “gatekeeper”. As a result, this study uses the theory of the industrial gatekeeping mechanisms to review the function of the exhibition, and take computer exhibitions COMDEX Fall, CeBIT, and COMPUTEX Taipei, which play very important roles in the ICT industry and have complete history, as examples. This study digs deeply into these three computer exhibitions and expects to find how the organizer of the exhibition positions itself in the earlier preparation stage. In addition, how does it play the role of the gatekeeping mechanisms well by delimiting the boundaries and sifting the content? Furthermore, how the organizer further impact the display of the exhibition with their gatekeeping function and ability, so that it could play different kinds of gatekeeping mechanisms in different exhibition events. Finally, this study wants to find the influence of industrial gatekeeping mechanisms results on innovative concepts, technology, and products in the industry, and investigates whether the results affect exhibitors and visitors’ will of participating in exhibitions . The conclusions of this study can be summarized as below: 1.There are three kinds of events, including “Trade Show”, “Conventions”, and “Award” in the exhibition. In the process of commercialization, these three events severally play different kinds of roles of gatekeeping mechanisms by delimiting the boundaries and sifting the content. →In the exhibition, the “Trade Show” belongs to the “Innovative gatekeeping mechanism”. →In the conventions of the exhibition, there are also three kinds of events, including “Keynote Speech”, “Forum”, and “Product Debut”. ”Keynote Speech” and “Product Debut” belong to the “Informational gatekeeping mechanism”, but “Forum” belongs to “Paradigm gatekeeping mechanism”. →In the exhibition, the “Award” belongs to the “Paradigm gatekeeping mechanism”. 2.For the exhibition organizer, its administration of gatekeeping mechanisms and its gatekeeping ability would affect each other. And the organizer would also reveal its gatekeeping ability in order to help itself carry out gatekeeping mechanisms. 3.The administration of the organizer’s gatekeeping mechanisms would be affected by itself organization types. 4.The organizer’s gatekeeping ability would be affected by itself organization types, resources, and networks. 5.The results of gatekeeping mechanisms of the exhibition, such as the diffusion of innovative concepts, technology, and products in the industry, would be influenced by industrial gatekeeping mechanisms of the exhibition. If the organizer doesn’t work industrial gatekeeping mechanisms of the exhibition well, it will lack representative and innovative display, and also affect exhibitors and visitors’ will of participating in exhibitions. Finally, the exhibition declines and falls. 6.The result of gatekeeping mechanisms would be deeply affected by the development of the industry which the organizer holds the exhibition in, and it develops with its industrial life cycle. Besides, the development of the industry also affects the administration of industrial gatekeeping mechanisms of the exhibition.
