La thèse développe une étude de la dentelle Renaissance en tant qu’ écriture construite sur la performance des dentellières de Monteiro (Paraíba-Brésil) à partir des objectifs suivants : relever des informations sur des aspects historiques, sociaux, artistiques et commerciaux de l’activité dentellière en Europe, tout en prenant en compte dans cette trajectoire la présence de la dentelle Renaissance dans l’État de Paraíba. En nous basant sur les concepts de déterritorialisation (Deleuze, Guattari), de nomadisme (Maffesoli) ; de voix et de performance (Zumthor), nous avons analysé la production et la recréation de la dentelle par les dentellières de l’Association des Artisans de Monteiro – ASSOAM, dans le savoir-faire de la dentelle, et cela à partir de trois générations de dentellières de deux familles. Nous avons mis en avant des aspects qui touchent la culture (Geertz), l’identité (Castells) et la mémoire collective (Halbwachs) dans la fabrication de la dentelle et dans l’enseignement et l’apprentissage de cet art, en approfondissant l’étude développée dans une recherche antérieure sur la dentelle Renaissance à Monteiro. Nous avons observé sa permanence au long des générations, avec des points considérés traditionnels et un processus de (re)création de nouveaux points, comparés aux images de points de la dentelle Renaissance produite en France au début du XXème siècle. Nous avons reconstitué l’histoire de la dentelle Renaissance en y incluant sa trajectoire dans le Cariri de l’État de Paraíba. Prenant pour base les présupposés théoriques cités plus haut et la recherche de terrain orientée par l’Histoire Orale (Thompson) et par l’ethnographie (Levi-Strauss), nous avons enregistré (ou filmé) des témoignages et des conversations résultant d’entretiens semi-structurés avec les dentellières de la dentelle Renaissance du Cariri de l’État de Paraíba et des dentellières françaises, italiennes et belges. Les points ont été fixés au moyen de photos. Les résultats de l’analyse des données théoriques et pratiques ont montré que la dentelle se déterritorialise à travers des actions comme l’exode, les immigrations et des formes de commercialisation. Les voix des dentellières qui s’instaurent dans les formes de leurs points et leurs dessins révèlent la culture, la mémoire et l’identité de la femme dentellière. La dentelle se fait langage artistique, englobant des savoirs dont participent la voix en performance, dans une actio qui rend possible l’enseignement et l’apprentissage de la dentelle et la création (et recréation) des points. Ceux-ci interagissent, communiquent et apportent dans leurs formes, des textes oraux qui parlent de l’être dentellière, révèlent des lectures sur la création, le tisser, la survivance et l’amour des dentellières pour leur art. À chaque point tissé et/ou recréé, la dentellière réécrit l’histoire de sa vie et son empreinte dans les fils tissés. Ainsi, la dentelle Renaissance exprime, dans une image qui complète le texte oral des dentellières, sa construction comme écriture. / This thesis develops a study of Renaissance lace as a built writing inlacemakers performance from Monteiro (Paraíba-Brasil) by the followingobjectives: gather information about historical, social, artistic and commercialaspects of the lace activity in Europe, consindering in this path Renaissancelace presence in Paraíba. Based on the concept of deterritorialization (DELEUZE; GUATTARI, 1995), nomadism (MAFFESOLI, 2001), and voice and performance (ZUMTHOR, 1993). It was analyzed the lace production and recreation by lacemakers of Monteiro handicraft workers association – ASSOM, at the lacemaking know-how, also about three generations of a lacemaker family. Cultural emphasis (GEERTZ, 1989), identity (CASTELLS, 2000) and collective memory aspects (HALBWACHS, 2004) are given at lacemaking and teaching learning of this art, also deepening this work on a previously initiated research about Renaissance lace in Monteiro. It was observed its maintenance through generations, with stitches considered traditional and the process of (re)creation of new ones compared to images of Renaissance lace stitches produced in France in the beginning of the 20th century. The history of Renaissance lace including its trajectory in Paraíba Cariri is rebuilt. Based on the theories mentioned above and on a field research guided by Oral History (THOMPSON, 1998) and by the ethnography (LÉVI-STRAUSS, 1996), testimonials and conversations were recorded (and/or filmed) with Renaissance lacemakers from Cariri in Paraíba, and included French, Italian and Belgian ones. The stitches were registered on photographies. The analysis results of the theorical and practical information shows lace deterritorialization in actions such as exodus, immigration, and in ways of commercialization. The lacemaker voices that are placed in the shapes of stitches and drawings reveal culture, memory and identity of the lacemaker woman. Lace became artistic language, which involves knowledge sharing by the voice in performance in an action that makes possible lace teaching and learning, and also creating (and recreating) the stitches. They get into interaction, communication and bring in their shapes oral texts that talks about what being a lacemaker is. They show off a reading about creation, the weave, the surviving and the love for their art. At each created or recreated stitch, a lacemaker rewrites her life history and her mark on the cloth tread. Thus, Renaissance lace express in an image that complete the lacemakers oral text their construction as a writing.

Michelin Ltda.", município de Itiquira - MT (17º22'23''S, 54º44'23''W). Foram realizados três ensaios para determinar a ocorrência, porcentagem de parasitismo e flutuação populacional da praga e parasitóides em talhões com e sem aplicação de produtos fitossanitários. Também foi verificada a influência a idade da folha de seringueira na oviposição de L. heveae e na ocorrência de parasitóides e a distribuição espacial de parasitóides nos lados dos talhões, em cinco clones de seringueira (RRIM 600, PR 255, PB 217, PB 235 e GT 1). Nos ensaios realizados eram coletadas folhas maduras (completamente expandidas), sendo demarcadas as áreas contendo os ovos de L. heveae, do terço inferior da copa de árvores dos cinco clones estudados. No ensaio correspondente à influência da idade das folhas, além de folhas maduras, eram coletadas folhas intermediárias (semiexpandidas e verde-claras) e novas (não expandidas e arroxeadas). Em todos os ensaios realizados a espécie Erythmelus tingitiphagus (Hymenoptera: Mymaridae) foi a mais abundante e freqüente. A porcentagem de parasitismo de E. tingitiphagus sobre ovos de L. heveae variou entre 13,8% no clone PB 235 a 30,8% no RRIM 600 em condições naturais. Os picos populacionais de L. heveae e de E. tingitiphagus deram-se nos meses de outubro e novembro nas áreas estudadas. Verificou-se que a distribuição de E. tingitiphagus ocorreu de maneira eqüitativa nos lados dos talhões, com tendência a concentrar-se no centro dos mesmos. A oviposição de L. heveae é maior em folhas maduras em relação às intermediárias e novas. / Abstract: The objective of this work was to make a survey of parasitoids associated with Leptopharsa heveae (Hemiptera: Tingidae) in lots of rubber trees cultivation on the farm of the company "Plantações E. Michelin Ltda.", municipality of Itiquira - MT (17º22'23'', 54º44'23''W). Three experiments were made to determine the occurrence, percentage of parasitism and population flotation of the pest and parasitoids in lots with and without application of pesticides. Also the influence of the age of the rubber tree leaf was verified in the oviposition of L. heveae and in the parasitoids occurrence and the space distribution of parasitoids beside the lots, in five rubber tree clones (RRIM 600, PR 255, PB 217, PB 235 and GT 1). Through the experiments made, ripe leaves were collected (completely expanded), being demarcated the areas containing L. heveae's eggs, of the inferior third of the canopies of the five studied clones. In the experiment corresponding to the influence of the age of the leaves, besides ripe leaves, intermediate leaves were collected (semi-expanded and light green) and new (unexpanded and purple). In all experiments made, the species Erythmelus tingitiphagus (Hymenoptera: Mymaridae) was the most abundant and frequent. The percentage of parasitism of E. tingitiphagus on eggs of L. heveae varied between 13.8% in the PB 235 clone, to 30.8% in RRIM 600 in natural conditions. L. heveae's and E. tingitiphagus's population picks happened in the months of October and November in the studied areas. It was verified that that the distribution of E. tingitiphagus happened in an equal way in the sides of the lots, with tendency to concentrate in the center of themselves.

In Natal, Rio Grande do Norte, Brazil, among many types found, identifies itself with the production of bobbin-lace, still practiced in Ponta Negra Village for ancient craftswomens of city that try to preserve the art and tradition of bobbin-lace. This work presents the results of an analysis conducted based in concepts of anthropotechnology, on the effects of a design workshop held with bobbin-lace craftswomen in the village of Ponta Negra in July of 2006. The workshop was intended to propose a new concept of products and a new alternative for production in the activity of the craftswomen, on the premise that the laces could be used as a detail inserted into other industrial products such as shirts, bags, towels, etc. Evaluations after the workshop showed that none of the artisans continued to work, indicating that actions focused solely on products did not generate representative results in the production of bobbin-lace. Evaluations also indicated that knowledge about the artisan's personal and professional characteristics, organization, pace, workload, and cultural and historical issues that permeate the activity are essential to the success of technology transfer, particularly when the transfer affects the craft production as it relates to the inseparable aspects of the craftswomen's work and lifestyle / O setor de produ??o artesanal brasileiro tem importante participa??o na gera??o de ocupa??o e renda de muitas fam?lias em todos os estados da federa??o, tendo em cada um, diferentes tipologias de artesanato. Em Natal, RN, dentre muitas tipologias encontradas, identifica-se a Renda de Bilro, uma arte introduzida no Brasil pelos colonizadores portugueses e ainda praticada na Vila de Ponta Negra por antigas rendeiras de bilro da cidade que tentam preservar a arte e tradi??o da renda. Esta pesquisa apresenta a an?lise dos resultados e repercuss?es de uma Oficina de Design realizada com um grupo de 19 rendeiras de bilro da Vila de Ponta Negra, al?m de expor os motivos pelos quais os ensinamentos repassados na Oficina n?o foram incorporados a atividade das artes?s. Para tal, utilizou-se como base te?rica a antropotecnologia e como base metodol?gica a An?lise Ergon?mica do Trabalho (AET). A referida Oficina de Design tinha como objetivo propor um novo conceito de produto e uma nova alternativa de produ??o a serem introduzidos ? atividade das rendeiras, partindo da premissa de utiliza??o da renda como detalhe a ser inserido em outros produtos industriais, como camisetas, bolsas, toalhas, etc, diferenciando-se da produ??o tradicional realizada pelas artes?s em que s?o produzidas blusas, saias, vestidos, tolhas, etc. totalmente em renda. Avalia??es realizadas ap?s a oficina mostraram que nenhuma das artes?s deu continuidade aos trabalhos de forma espont?nea, indicando que a??es pontuais focadas apenas nos produtos n?o geram resultados representativos na produ??o da renda de bilro, e que o conhecimento das caracter?sticas pessoais e profissionais das artes?s, organiza??o, ritmo e carga de trabalho, quest?es culturais e hist?ricas que permeiam a atividade s?o primordiais para o sucesso das transfer?ncias de tecnologia, principalmente quando estas transfer?ncias est?o relacionadas ? produ??o artesanal, em que o modo de vida e de trabalho dos artes?os ? indissoci?vel

Nossa pesquisa visa problematizar o dispositivo de grupo a partir da psicanálise lacaniana. A questão da qual partimos foi: Se a psicanálise aponta para o singular do sujeito, como trabalhar com dispositivos de grupos sem dissolvê-las num universal? Num primeiro momento, mapeamos alguns elementos históricos do surgimento da noção de grupo. Extraímos daí que tal noção nasce concomitantemente à noção de indivíduo, ambos tomados como totalidades. A psicanálise, por sua vez, não parte do indivíduo, pois tem como fundamento e horizonte de intervenção o sujeito, de forma que o dispositivo de grupo também deve levá-lo em conta. Na sequência, o tema grupo é investigado nas obras de S. Freud, W. R. Bion, E. Pichon-Rivière, J. Lacan procurando extrair-lhes uma lógica coletiva. A partir de Freud, temos um esquema no qual a tendência do grupo é fazer massa, identificando-se ao mesmo tempo verticalmente sob uma insígnia do mestre colocado como Ideal do Eu, e horizontalmente entre os sujeitos a partir do Eu, tendendo a apagar suas singularidades através de um grupo imaginariamente completo. Com isso, vemos a questão da identificação se tornar um problema central na questão dos grupos. Assim procuramos elementos que pudessem nos auxiliar para que o grupo não ceda aos efeitos imaginários. Frente a isso, Bion trouxe uma primeira contribuição do grupo sem líder, para quem o analista não atua do lugar de líder, trazendo a importante ideia de descompletar o grupo; Pichon, por sua vez, traz a ideia de interdependência dos sujeitos afirmando uma lógica coletiva, uma vez que os sujeitos não são mônadas isoladas. Na sequência, foi importante o recurso ao dispositivo de cartel, órgão de base da Escola lacaniana, o qual aponta para um grupo não completo, dado que a função do +1 é justamente descompletar o grupo a fim de mitigar seus efeitos imaginários. Nosso próximo passo foi abordamos os efeitos de sujeito - em oposição aos efeitos imaginários - a partir do recurso de vinhetas clínicas de atendimentos de grupos em articulação à contribuição lacaniana da sua tríade Imaginário, Simbólico e Real. A consideração desses três registros apontou para outro modo de universalizar um grupo como prescindindo do significante, uma vez que o que Lacan denominou como objeto a escapa às suas determinações simbólicas e imaginárias em suas tendências identificatórias e homogeneizantes. Extraída tal lógica coletiva, apontamos que o analista num grupo tem sua função ancorada no objeto a. Além disso, o analista deve considerar os efeitos da fala que os sujeitos têm entre si, visto que a transferência circula entre os sujeitos. Uma vez que os sujeitos em grupo tendem a responder às demandas um do outro, concluímos que é importante ao psicanalista fazer circular a palavra, de modo a manter a significação aberta, para que ninguém venha a ocupar o lugar de Ideal do Eu. Por fim oferecemos um quadro de leitura das experiências ambivalentes de grupo: como experiências produtivas (de determinação e indeterminação), mas também improdutivas (de indeterminação e determinação). Finalmente, concluímos que o dispositivo de grupo pode ser um importante dispositivo de intervenção clínica, ética e política para o campo da Saúde / This research aims to problematize the device group from Lacanian psychoanalysis. The question with which we started was: If psychoanalysis points to the singular subject, how to work with groups devices without dissolving them in a universal? Initially, we mapped some historical elements of the emergence of the notion of group. We extracted from this that such notion is born simultaneously with the notion of the individual, both taken as totalities. Psychoanalysis, in turn, does not arise from the individual, because it is based and has as intervention goal the subject, so that the device group should also take it into account. Subsequently, the group theme is investigated in the works of S. Freud, Bion, E. Pichon-Rivière J. Lacan seeking to extract from them a collective logic. From Freud, we have a scheme in which the tendency of the group is to make dough, identifying both vertically under a master insignia placed as the Ideal Self, and horizontally among subjects starting from themselves, tending to erase their singularities through an imaginary whole group. Therewith, we see the issue of identification become a central point in the matter of groups. Thus we seek elements that could help us so that the group does not give in to imaginary effects. Faced with this, Bion brought a first contribution of the \"leaderless group\", to which the analyst does not act in the place of leader, bringing the important idea of not to complete the group; Pichon, in turn, brings the idea of interdependence of individuals stating a collective logic, since the subjects are not isolated monads. Thereafter, it was important to make use of the cartel device, organ base of Lacanian School, which points to a not complete group, since the function of the +1 is precisely not complete the group in order to mitigate its imaginary effects. Our next step was to approach the \"effects of subjects\" - as opposed to imaginary effects - from the use of clinical vignettes used on groups treatment in articulating their contribution to the Lacanian triad Imaginary, Symbolic and Real. The consideration of these three records, pointed to another way of universalizing a group as waiving significant, since what Lacan has termed as escape object to their symbolic and imaginary determinations in its identificatory and homogenizing trends. Extracted such collective logic, it is possible to indicate that, in a group, the analyst has his role anchored in the object. In addition, the analyst must consider the effects of speech that individuals have with each other, since the transfer circulates between subjects. Since the subjects in groups tend to respond to each other demands, we conclude that it\'s important the psychoanalyst to circulate the word, in a way to keep an open meaning, so no one will take the place of the Ideal I. Finally we provide a reading framework for the ambivalent group experiences: as productive experiences (determination and indeterminacy) but also unproductive (of indeterminacy and determination). Lastly, we conclude that the group device can be an important tool for clinical policy in the field of health care intervention and ethics

The outcome of my thesis is airy relief in the form of a spreaded Kyjov´s women's folk costumes. It is made up of embroidery and lace, which gets their original lightness without underlying substance.The white color, I have used, strenghts this feeling. All parts are printed by the ABS plastic. I follow the transformation of hand-made embroidery on the machine-made one with this. 3D printing is another entirely fictitious step for me. Just as the embroidery machine adjusts stitches according to their outline, as well as 3D printer has its own structure of applying material.

The inquiry of this subject is important to enable and to subsidize the work with adolescents, and to question and dicuss the binomial adolescence-violence. This is a practical work where the psychoanalys was used as subsidy for conception of adolescence and analysis of the interviews. The analysis was made from the psychoanalytic listenings of the attests and interviews, and it was made through the speeches that produce and reveal social laces. It was observed inside the Restorative Justice proposal the importance of the adolescent as not the only depositary of some many ways of the conflicts causes and solutions . Another consideration is that the structure in which he is inserted creats a coherent that contributes for the resolution and prevention of conflicts and infractional acts. The social laces the adolescent establishes is changeable and this different constitution of laces allude to the speech individual speech and social speech. The possibility of the word circulation brought from listening is essential, since it contains the transformation possibility of the social laces established by the adolescent / Justiça Restaurativa e o adolescente autor de ato infracional combinamse, nesta dissertação, de forma levantar elementos para compreender qual é a concepção do adolescente autor de ato infracional acerca do círculo restaurativo (enquanto prática da justiça restaurativa), o que esta experiência provocou no adolescente, bem como de que forma se deu a implicação pessoal do adolescente neste processo. Procurou-se compreender quais são as possibilidades de transformação no laço social do adolescente autor de ato infracional que experiencia a prática da Justiça Restaurativa. A investigação deste tema é importante para capacitar e subsidiar o trabalho com adolescentes, e para questionar/problematizar o binômio adolescênciaviolência. Este é um trabalho prático em que a psicanálise foi utilizada como subsídio para concepção de adolescência e para análise das entrevistas. A partir da escuta psicanalítica de depoimentos e entrevistas, a análise foi feita através dos discursos, que produzem e revelam formas de laços sociais. Dentro da proposta da justiça restaurativa, percebeu-se como imprescindível que o adolescente não seja o depositário único tanto das causas quanto das soluções dos conflitos e que a estrutura na qual ele está inserido forme um todo coerente que contribua para a resolução e prevenção de conflitos e atos infracionais. O laço social que o adolescente estabelece é mutável e as formas como este laço se dá estão referenciadas ao discurso discurso do sujeito e discurso social. A possibilidade de circulação da palavra trazida pela escuta é fundamental, visto que ela contém a possibilidade de transformação dos laços sociais estabelecidos pelo adolescente

Feito isso, confirmou-se que a atual organiza??o espacial do bairro de Nova Parnamirim partiu de dois loteamentos: o Parque Vale do Pitimb? e o Parque dos Eucaliptos, ambos fracionados em v?rios loteamentos menores, nas d?cadas de 80, 90 e 2000, conformando uma intricada estrutura fundi?ria urbana. Atrelado a isso, constatou-se a instala??o de uma l?gica de segrega??o e auto-segrega??o conduzida por um mercado imobili?rio que exclui os insolv?veis e absorve os solv?veis, motivado pela perspectiva de obten??o de rendas fundi?rias urbanas pelos promotores imobili?rios e pela migra??o de grupos da capital, do interior do Estado e de outras regi?es do pa?s. Os condom?nios fechados horizontais e verticais representam formas de produ??o de uma nova forma de moradia, no que diz respeito tanto aos padr?es arquitet?nicos como socioecon?micos, fortalecida pelo ideal de seguran?a, qualidade de vida, pela necessidade da reclus?o e da proximidade de Natal, com ?nfase para o consumo de bens e servi?os especializados e espec?ficos. Concluiu-se que h? uma valoriza??o do solo e da habita??o no bairro, o que refor?a a promo??o da segrega??o e da auto-segrega??o e, consequentemente, a reprodu??o capitalista do espa?o urbano

Lantana camara L. (Verbenaceae) remains a highly invasive and ecologically damaging weed in South Africa, despite some 50 years of biological control efforts. Lack of success has been ascribed to varietal differences, climate and predation of agents but these have not been tested. In this study, the effects of ant predation were tested on populations of three biological control agents for L. camara. Colonies of two species, Crematogaster sp. 1 and 2 were investigated. Crematogaster sp. 1 colonies were offered no choice between immature stages of the agents Hypena laceratalis Walker (Lepidoptera: Noctuidae), Falconia intermedia Distant (Hemiptera: Miridae) or Teleonemia scrupulosa Stål (Hemiptera: Tingidae) on lantana shoots. Density-dependent predation on F. intermedia and T. scrupulosa nymphs on lantana shoots was tested using Crematogaster sp. 2 colonies. In choice experiments Crematogaster sp. 2 colonies were offered F. intermedia or T. scrupulosa nymphs on potted lantana plants. Preliminary food trials confirmed that colonies foraged for protein, thereby validating results of no-choice experiments. Crematogaster sp.1 foragers removed 50% of F. intermedia nymphs, followed by 45% of H. laceratalis larvae and only 9% of T. scrupulosa nymphs. Foragers recruited most actively to H. laceratalis larvae and significantly more H. laceratalis biomass was removed than either F. intermedia or T. scrupulosa. A trade-off existed in prey size selection because larger larvae provided considerably more biomass but required forager cooperation and a longer time to subdue than did smaller prey. This increases both forager energy expense and mortality risk by other predators. This study showed that all Crematogaster sp. 1 colonies removed small (≤10mm) H. laceratalis larvae more frequently than larvae larger than 10mm. Thus, of these biological control agents, predators probably prefer small H. laceratalis larvae. Significantly more F. intermedia than T. scrupulosa nymphs were removed by Crematogaster sp. 1, while Crematogaster sp. 2 colonies removed comparable numbers of both agent species. Falconia intermedia nymphs' fast movement triggered a predatory response by these ant species. In contrast, the relatively immobile behaviour of T. scrupulosa nymphs was identified as a highly effective predator avoidance strategy. Since T. scrupulosa nymphs are unable to escape predators by moving, they appear to depend on the presence of alternative prey attracting predator attention. At high agent and/or forager density, T. scrupulosa nymphs attempted escape, but foragers identified them as prey once they moved and caught them. Predation on F. intermedia was also density dependent in that at high nymph and/or forager densities, escape routes were congested and nymphs were more easily caught. Survival of F. intermedia and T. scrupulosa nymphs in particular was low on ant-accessed shrubs in choice experiments and high on ant-excluded shrubs. It is likely that ants significantly depress F. intermedia populations in the field since besides predation, ant foragers probably interrupt F. intermedia feeding and ovipositioning. The combination of parasitism and predation on early instar larvae may explain why H. laceratalis occurs across lantana's range in South Africa but populations remain low. It is unlikely that T. scrupulosa nymphs are habitually preyed on by ant species unless they attract attention by being mobile. Although biological control of L. camara is influenced by climate and physiological defence mechanisms, this study has shown that predation by two ant species severely impacts leaf-feeding agents for L. camara. Thus, it is recommended that future selection of additional agents to control lantana should exclude leaf-feeding .
