Desempenho biológico de indivíduos solitários e gregários de Trichogramma pretiosum Riley, 1879 (Hym.:Trichogrammatidae) em diferentes densidades do hospedeiro Corcyra cephalonica (Stainton, 1866) (Lep.: Pyralidae) /

Cardoso, Warner Gasparini. January 2016 (has links)
Orientador: Sergio Antonio De Bortoli / Banca: Ricardo Antonio Polanczyk / Banca: Ana Carolian Pires Veiga / Resumo: Este estudo objetivou determinar a influência de diferentes razões de número de ovos de Corcyra cephalonica, no desenvolvimento gregário e solitário de Trichogramma pretiosum, bem como avaliar os desempenhos biológicos e morfométricos de insetos que se desenvolveram de forma solitária e gregária. Foram oferecidas a uma fêmea de T. pretiosum, quatro diferentes densidades de ovos do hospedeiro alternativo C. cephalonica separadamente (5, 10, 20 e 30) por três dias consecutivos (dias 1, 2 e 3). Colocou-se uma fêmea, em tubo cilíndrico de fundo chato (8 cm × 2 cm), em contato com uma cartela contendo ovos do hospedeiro e uma gotícula de mel como alimento. A cartela foi trocada diariamente até a fêmea completar o terceiro dia de vida. Foram avaliadas as porcentagens de parasitismo, emergência de ovos parasitados, e o número de adultos emergidos por ovo, para cada uma das densidades. Em outra etapa, foram realizados testes com os descendentes de T. pretiosum provenientes da emergência de adultos solitários e gregários. Foi oferecido um único ovo hospedeiro exposto à oviposição por 1 dia, para uma única fêmea parasitoide, e individualizado em tubo de plástico (7,5 cm × 1 cm) contendo uma gotícula de mel. Foram avaliadas as porcentagens de parasitismo, de emergência e a longevidade de adultos, além de parâmetros morfométricos dos descendentes gregários e solitários. A relação mais baixa de hospedeiros apresentou 90% de ovos parasitados com a fêmea na idade de um dia, sendo que 68,7% ...

We were offered to one female parasitoids, four different densities of eggs of the factitious host C. cephalonica (5, 10, 20 and 30) for three days consecutive (days 1, 2 and 3). The female was placed in cylindrical tube (8 cm × 2 cm) in contact with a paperboard containing eggs of the host and a droplet of honey as food. This paperback was changed daily until the female complete the third day of life. The parasitism were evaluated, emergency of parasitized eggs and the number of emerged adults per egg for each offered densities. In another step, tests were performed with the descendants of parasitoids from the emergency solitary and gregarious adults. A single host egg oviposition exposed for one day in individual plastic tubing (7.5 cm × 1 cm) having a honey drop offered. The parasitism were evaluated, emergency and longevity of adults, and morphometric parameters of gregarious and solitaries progenies. The lower ratio hosts showed 90% of parasitized eggs with the female at the age of one day, and 68.7% of these have emerged. The development up two individuals per egg host was observed in all densities during the three-day supply of eggs, and the emergence of one individual was predominant. Adults emerging from solitary parasitize 20.5% more than gregarious and longevity of both did not differ significantly. The body size and the last posterior left tibia was significantly different, being 0.09 mm and 0.03 mm, respectively, higher in solitary adults. Host of different densities, it was possible to significantly lower the ratio, the more adults emerging from an egg C. cephalonica, with the same biological and morphometric ...

A patient with the diagnosis of a "factituous disorder": a phenomenological investigation

Bosch, Adrian Frans 29 January 2004 (has links)
In this dissertation, the author provides an account of his therapeutic interaction and experience, as an intern clinical psychologist, in working with a patient in psychotherapy who was eventually diagnosed with a “factitious disorder”. This study descriptively addresses how the therapeutic interaction impacted upon the therapist’s thinking of the process both diagnostically and in terms of therapeutic goals. This study consists of a single case, qualitative research design. It concerns the interactions and experiences of the therapist with a specific patient (diagnosed with a factitious disorder) in the context of a multidisciplinary academic hospital setting. The study aims to be predominantly descriptive of this therapy, and as such employs the psychological phenomenological method of Giorgi (1985) in order to provide a specific description of the situated structure of the therapy. As such, this study is able to contribute to the sparse psychological and therapeutic information available on factitious disorders. There are few detailed accounts of actual therapeutic interactions – specifically from a psychological perspective – for patients diagnosed with factitious disorders. The specific description of the situated structure of the therapy is also compared to the available literature on factitious disorders. Although the aim of this study was not evaluative in nature, the author does provide some tentative comments on the aetiology and therapeutic considerations for factitious disorders – with regards to this particular case. The author suggests a strong link to personality and character deficits underlying factitious behaviour. The author further suggests the importance of acknowledging the “sick role”; allowing for “face-saving” strategies; providing consistency (on behalf of the therapist); and the setting of rigid, overt, therapeutic boundaries in the psychotherapeutic treatment of factitious disorders. / Dissertation (MA (Clinical Psychology))--University of Pretoria, 2005. / Psychology / unrestricted

由唐迄宋的迷樓研究──迂迴與幻象 / The Study of Milou: Detour and Fantasy

賀淑芳, Ho Sok Fong Unknown Date (has links)
從「迷樓」的敘事研究可投射出「享樂」與「匠藝」的兩大圖像。本論文的論述分成兩個層次,一個層次從唐宋期間各種不同類型的文本和文體來探討「迷樓」典故中的欲望與當時的話語現象的關係,涵蓋唐宋時二元對立的一系列價值如節制/放縱、儉/奢、自然/人工。另一個層次則是以「迷樓」的欲望與技術,來比擬文學創作意識中的欲望與技巧的問題,後者觸及詩學中的自然風格與人工技術或「工巧」之間的辯證關係。 迷樓不見於任何官方正史及私家撰述的史籍,它主要見於詩、詞、賦、小說逸史、方志和筆記或札記。根據方志,揚州被認為位於揚州,但在文學作品中,卻有迷樓位在揚州、長安、洛陽之說,本文認為,從唐宋詩詞的空間意象來看,迷樓其實更近於一種散佈於汴淮流域的想像空間,顯見「迷樓」有傳聞異辭的性質。雖然這篇論文有探究方志與文學文本中迷樓地點所在的問題,然而目的並非志在斷定迷樓「實體」存在與否、或存在於何處,而是在提供一種背景來理解唐宋時期人們對迷樓所在的認同差異與相關的空間敘述。 根據小說《迷樓記》的敘述,迷樓是煬帝所建的一座結構宛若迷宮的宮殿,它也是一個承載「極樂」想像的空間。「極樂」在宋代的養身論與主張節制的話語之中是需被抑制的一種禁忌。故此,有關「迷樓」中的「極樂」敘述是在尋回如同拉康所言的某種早已被排除出去的「愛欲」或原初已經失落的「歡爽」,人們對這種「極樂」的境界充滿想像,對於「極樂」的渴求威脅著主體賴以生存的經濟制度與權力體制乃至耗竭個人的身體。在此也參考巴塔耶的色情史理論,來說明主體也會渴求某種迷失自我的欲望。本文也將隋煬帝在迷樓內「浪費的技術」(即同時耗損自身精氣、浪費「發明」的技能、揮霍國家的財富)也延伸到詩學裡詩歌藝術裡一種創作技術上的魅力,來回扣宇文所安《迷樓:詩與欲望的迷宮》中以迷樓作為論述結構的「比擬」。本文也試圖以「迷樓」來「比擬」唐宋期間勾連自然與技巧的文學觀念,詩人為此心搖神馳,對文學技巧追求完美的「欲望」,使得欲望從現實空間「逃遁」到文學空間裡來,追求天工般技巧所造的詩境。 中國人傾向於將政權興亡與自然現象互比相連,使得興、亡循環成為必然發生且無可避免的現象,這種對於興亡循環有其必然性的觀念反而削弱了諷喻文學規勸帝王的實質功能。這正是迷樓作為諷喻的典故所盤結的重重矛盾與衝突之所在。意識到「諷喻」在啟悟他人功能上的侷限,詩歌作為高度創作與獨立自足的藝術性質更受重視,如唐宋詩學中有頗多詩話與詩評大量闡述詩歌創作的理想,崇尚以不鑿痕跡的技巧,來達到完美「自然」的詩境。 在唐宋兩代,可以發現在歷史處境的衝擊下,迷樓典故亦有所衍異,並被詩人加以部署以訴說個人的生命情境。唐宋兩代旅人在揚州岸外的長江與運河水道上曲曲折折的移動經驗,這種移動經驗也賦予迷樓遺址特殊的意象,無論是在遠離或接近揚州,蜀岡上的迷樓遺址都被包裹在迂回曲折的路線地圖裡,從迂迴到昇華,迷樓成為想像中登高地點的所在。在有意託諷之下,迷樓的敘事並不純粹只是過往歷史的回顧,同時也是當代歷史的指涉。 除了作為社會性敘事的諷喻功能之外,本論文最後也在兩個層次上回扣宇文所安以迷樓作為文學論述與詩學上的「比擬」:一、迷樓作為個體欲望縷織下與群體相隔離的藝術空間;二、傳聞中迷樓是一座在技術上巧奪天工的宮殿,在詩歌中「迷樓」經常被強調作為一種人工成果,與自然對立。通過這種自然──天工對比的論述,本文也嘗試指出迷樓足可比擬文學裡透過崇尚自然風格征服人工鑿痕的觀念。 / Through the variety of texts and genres from Tang to Sung, the narration of “Milou” had projected the figure of pleasure and exquisite craftwork. The inquisitions of this essay consist of two layers. First, to addresses the relation of the desire and the discursive phenomena at the time of Tang to Sung, especially on the binary aspect of temperance and pleasure, frugality and luxury, nature and craftsmanship. Secondly, to mate the dazzling craftwork of Milou correspondent with the desire and pleasure of the attentive craftwork in literary world, in which the dialectical relation between the Nature and craftsmanship was deeply concerned. Neither the official nor the private historical texts have any record on Milou. However, the allusion and narration of Milou was found in variety of texts including poets, rhapsodies, lyrics, novels, geographical documents and notes. According to the novel “The Tales of Milou”(Milou Ji, 迷樓記), Milou was a labyrinthine palace built by Shui Yang Ti, a space loaded with the imagination of “utmost enjoyment”(Ji Le, 極樂). The utmost enjoyment had been known as a forbidden state in the discourse on regimen, it was also considered as a dangerous force which threatening to the nation. The inquisition of “utmost enjoyment” has been linked to the “technique of waste”, which provoke the exhaustion of the King’s body, and also the waste of accumulative wealth of the kingdom, and brought huge chaos and doom to the dynasty. My argument of the “technique of waste” has extended to the discussion of creative technique involved in literary writing, which had been gaining a lot of attention in late-Tang and Sung, poets were aware of the poor efficacy of “critical allegory” (feng yu諷喻) due to the paradox of flourish and fading which had been seen as nature mechanism, as has been pointed out by Stephen Owen. Poetry had gained its own sovereignty; poetic commentators had discussed the technique of creation enthusiastically and pursued for the perfect poetic scene(境). There are two layers of discussion which closely interrelated with each other: 1. Milou was a symbol of pleasure and crafty achievement, and thus contradictory to the Nature. 2. This essay has further elaborated the relation of the crafty image of Milou with the “clever technique” (巧工) in the poetic notion from Tang to Sung. However, to achieve perfect work for poetry that look like the work of nature(天工), it definitely had to be created through superb technique that can smooth away any crafty traces.

Att vara sjuk för någon annans skull : En litteraturstudie om att tidigt upptäcka föräldrar med Münchausen Syndrome by Proxy

Aldenhamn, Nathalie, Askling Wall, Christopher January 2020 (has links)
Bakgrund: Munchausen syndrome by proxy (MSBP) är en psykisk sjukdom som drabbar föräldrar där barnet/barnen blir offer. Föräldrarna, ofta modern drivs av uppmärksamheten de får av sjukvården. Föräldrarna manipulerar sjukvårdspersonalen då de ofta blir indragna i misshandeln genom diverse behandlingar/ingrepp. Svårigheter med att påvisa misshandeln för allmänsjuksköterskan/sjukvårdspersonalen är svår då det sker i det tysta samt att kunskapen kring MSBP är liten. Vid all misstanke om att ett barn far illa har sjukvårdspersonalen anmälningsplikt och på så sätt kan barnens rättigheter enligt Barnkonventionen skyddas. Syfte: Syftet var att undersöka faktorer som kan leda till tidig upptäckt av förälder med MSBP. Metod: En kvalitativ litteraturstudie baserad på case studies/case reports som innehåller narrativa berättelser som bygger på empiri och induktiv ansats. Litteraturstudien genomfördes utifrån Polit och Becks (2017) niostegsanalys.   Resultat: Fyra kategorier framkom. Vanliga symtom hos barnen, vanliga undersökningar av barnen, vanlig behandling av barnen samt beteenden hos barn respektive föräldrar. Slutsats: De faktorer som vårdpersonal ska vara uppmärksamma på är barns beteendeförändringar och förseningar i utvecklingen, föräldrar som för barnets talan, som ej lämnar barnets sida på sjukhuset samt vill ta och lämna in egna provmaterial från sitt barn. En annan faktor är familjer som frekvent söker vård för sitt barn eller varit inlagda trots att ingen sjukdom kunnat diagnostiseras eller bekräftats till följd av de diffusa symtomen som funnit hos barnen. Ytterligare en faktor är familjer som har haft många vårdkontakter och flyttar ofta. För att denna medvetenheten ska finnas behöver kunskap kring Münchausen Syndrome by Proxy spridas.

The predator ladybeetles are part of the biological control agents of agricultural pests, could be management by the three biocontrol strategies: classical, conservative and augmentative. In the present work, it was tried to generate knowledge for using the aphidophagous predator ladybeetle Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae) under the perspective of the last two strategies. The conservative biological control involving predator insects bases on the fact that in the absence or scarceness of their preferential prey or in the presence of the other preys with inferior nutritional quality, they may use alternative foods, such as pollen, to guarantee their survivorship and, sometimes, their reproduction, and because of that botanical species that provide this floral resource might integrate the agricultural landscape, inside and/or around the agricultural property; meanwhile the augmentative control requests the multiplication of the predator in the laboratory, using natural or artificial preys. Even though some authors proved the visitation of the flowers of some species of Apiaceae by C. maculata, there are no records in the literature of the ingestion of pollen grains of this botanical family by this ladybeetle. In this context, this work was carried out with the aim to select the plant species whose flowers are source of pollen as alternative or complementary food to C. maculata in the perspective to compose the vegetation of the agroecosystems to contribute in the conservation of this ladybeetle, and /or to aid in its mass rearing in the laboratory conditions. The objective of the chapter I was to prove the ingestion of pollen of three species of the family Apiaceae [coriander (Coriandrum sativum L.), dill (Anethum graveolens L.), and fennel (Foeniculum vulgare Mill.)] from the provision of their flowers to the larvae of the 4th instar and adults of C. maculata. It was observed the presence of pollen grains in the five replicates of all treatments, proving the ingestion of the pollen of these three species of Apiaceae from their flowers by C. maculata. At 24 hours of exposition, adults fed on average more pollen of dill than pollens of coriander and fennel, while the larvae consumed more pollen of fennel. The objective of the chapter II was to determine the suitability of nine diets to C. maculata, including provision of pollen of the two species of Apiaceae (coriander and dill), under controlled conditions of the laboratory. Even though the diets with only flowers of these two Apiaceae did not provided the full development of C. maculata, they used as complementary food with eggs of Anagasta kuehniella Zeller (Lepidoptera: Pyralidae) resulted in reduction of larval period, increased the egg number by cluster, and increased the body weight. The diet with alive larvae of Drosophila melanogaster Meigen (Diptera: Drosophilidae) was proved to be an essential food as well as resulted in adults with higher body weight, and the number of eggs per cluster increased in comparison with the feeding with only eggs of A. kuehniella. / O controle biol?gico ? um importante m?todo para regular as populac?es de pragas em um sistema de produ??o agr?cola sustent?vel, pois ? uma alternativa promissora ao uso de agrot?xicos org?nicos sint?ticos que causam grandes impactos ecotoxicol?gicos. As joaninhas predadoras fazem parte dos agentes de controle biol?gico de pragas agr?colas, podendo ser manejadas pelas tr?s estrat?gias de controle biol?gico: cl?ssico, conservativo e aumentativo. No presente trabalho, buscou-se gerar conhecimento para uso da joaninha predadora afid?faga Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae) sob a perspectiva das duas ?ltimas estrat?gias. O controle biol?gico conservativo envolvendo insetos predadores baseia-se no fato de que, na aus?ncia ou escassez da presa preferencial ou na presen?a de outras presas de qualidade inferior, podem usar alimentos alternativos, tais como p?len, para garantir sua sobreviv?ncia e, por vezes, sua reprodu??o e, por isso, esp?cies bot?nicas provedoras desse recurso floral devem integrar a paisagem agr?cola, dentro e/ou no entorno da propriedade agr?cola; enquanto o controle aumentativo requer a multiplica??o do predador no laborat?rio, podendo se valer de presas naturais ou artificiais. Apesar de alguns autores comprovarem a visita??o das flores de algumas esp?cies de Apiaceae por C. maculata, n?o h? relatos na literatura da ingest?o de gr?os de p?len dessa fam?lia bot?nica por essa joaninha. Nesse contexto, este trabalho foi conduzido a fim de selecionar esp?cies de plantas cujas flores sejam fonte de p?len como alimento alternativo ou complementar para C. maculata na perspectiva de compor a vegeta??o dos agroecossistemas para contribuir na conserva??o dessa joaninha, e/ou auxiliar na cria??o massal da mesma em condi??es de laborat?rio. O objetivo do cap?tulo I foi comprovar a ingest?o de p?len de tr?s esp?cies da fam?lia Apiaceae [coentro (Coriandrum sativum L.), endro (Anethum graveolens L.) e erva-doce (Foeniculum vulgare Mill.)] a partir da oferta de suas flores para larvas de 4? instar e adultos de C. maculata. Constatou-se a presen?a de gr?os de p?len nas cinco repeti??es de todos os tratamentos, comprovando a ingest?o de p?len dessas tr?s Apiaceae a partir de suas flores por C. maculata. Em 24 horas de exposi??o, os adultos consumiram em m?dia mais p?len de endro em compara??o aos polens de coentro e erva-doce, enquanto que as larvas consumiram mais p?len de erva-doce. O objetivo do capitulo II foi determinar a adequabilidade de nove dietas para C. maculata, incluindo oferta de p?len de duas esp?cies de Apiaceae (coentro e endro), em condi??es controladas de laborat?rio. Apesar das dietas apenas com flores dessas duas Apiaceae n?o proporcionarem o desenvolvimento completo de C. maculata, elas usadas com complementa??o da alimenta??o com ovos de Anagasta kuehniella Zeller (Lepidoptera: Pyralidae) possibilitam a redu??o do per?odo larval, aumento no n?mero de ovos por postura e aumento do peso corp?reo. A dieta com larvas vivas de Drosophila melanogaster Meigen (Diptera: Drosophilidae) n?o foi s? comprovada como alimento essencial como tamb?m resultou em adultos de maior peso corp?reo e um aumento no n?mero de ovos por postura em compara??o ? alimenta??o apenas com ovos de A. kuehniella.
