Abstract
This paper aims to show how the forms of multiculturalism values are displayed in Amina's life and how multiculturalism can change the perspective of other characters towards multiculturalism in the novel Amina's Voice (2017), written by a Pakistani-American writer, Hena Khan. This novel tells about a girl named Amina who has a family background from Pakistan and has long lived in Milwaukee, Wisconsin, United States. Despite living in a dominant Western culture, the Amina family consistently upholds Pakistani cultural values and uses their native customs daily. The differences between these two cultures often lead to conflicts experienced by Amina and other characters in the story. Despite encountering obstacles, Amina is shown still to practice the values of multiculturalism in her daily life. This study uses the concept of indicators of multiculturalism values proposed by Tilaar (2004) and the concept of acculturation written by Berry (2005). This research shows that there are forms of multiculturalism values found in the three spheres of Amina's life, namely in the family, school, and social environment. The indicators of multicultural values are learning in diversity, mutual trust, mutual understanding, mutual respect, open-mindedness, appreciation and interdependence (mutual dependence), and conflict resolution. In addition, the present writer also found that the practice of multiculturalism that occurred in the text resulted in an acculturation process that succeeded in changing the perspective of Amina's family members towards the value of multiculturalism.
Keywords: acculturation, multicultural, multiculturalism values
Abstrak
Tulisan ini bertujuan untuk menunjukkan bagaimana bentuk nilai-nilai multikulturalisme ditampilkan dalam kehidupan Amina dan bagaimana praktek multikulturalisme dapat mengubah cara pandang tokoh lain terhadap multikulturalisme di dalam novel Amina’s Voice (2017) yang ditulis oleh seorang penulis Pakistan-Amerika, Hena Khan. Novel ini menceritakan tentang seorang anak perempuan bernama Amina yang memiliki latar belakang keluarga dari Pakistan yang sudah lama menetap di Milwaukee, Wisconsin, Amerika Serikat. Walaupun hidup di tengah budaya Barat yang sangat dominan, keluarga Amina secara konsisten tetap menjunjung tinggi nilai budaya Pakistan dan menggunakan adat-istiadat asal mereka di kehidupan sehari-hari mereka. Perbedaan 2 budaya ini kerap kali mendatangkan konflik yang dialami Amina dan tokoh-tokoh lain di dalam cerita. Walaupun mengalami kendala, Amina ditampilkan tetap mempraktekkan nilai-nilai multikulturalisme di dalam kehidupan sehari-harinya. Dalam penelitian ini, penulis menggunakan konsep indikator nilai-nilai multikulturalisme yang dikemukakan oleh Tilaar (2004) dan menggunakan konsep akulturasi yang ditulis oleh Berry (2005). Hasil dari penelitian ini adalah terdapat bentuk-bentuk nilai multikulturalisme yang ditemukan di tiga ruang lingkup kehidupan Amina, yaitu di lingkungan keluarga, sekolah, dan sosial. Adapun indikator nilai multikultural yang ditemukan adalah belajar hidup dalam perbedaan, membangun saling percaya, memelihara saling pengertian, menjunjung sikap saling menghargai, terbuka dalam berpikir, apresiasi dan interdepedensi, dan resolusi konflik. Selain itu, penulis juga menemukan bahwa praktek multikulturalisme yang terjadi di dalam teks menghasilkan proses akulturasi yang berhasil mengubah cara pandang anggota keluarga Amina terhadap nilai multikulturalisme.

The Health Equity Network of the Americas (HENA) is a multidisciplinary network that promotes knowledge sharing and intersectoral action for equity in health and human rights in the Americas. The objectives of HENA are: 1) to share successful experiences in the development of interventions, considering the social determinants and determination of health, to achieve participatory and community-based health responses; 2) to analyze the health, social, political, environmental and economic impacts of the COVID-19 pandemic; 3) to identify the effects of pandemic care on populations most at risk because of their age and pre-existing health conditions; 4) examine the situation at borders and population movements in the spread of the pandemic and its effects on migrant populations; 5) propose strategies to ensure access to comprehensive care for pregnant women in order to reduce maternal and neonatal suffering, morbidity, and mortality; and 6) analyze violations of human rights and the right to health of historically marginalized populations, including street dwellers and other communities that depend on public spaces and the street for survival. The analytical and intervention models for health equity at HENA are based on various approaches, including social medicine, social epidemiology, medical anthropology, human ecology, and One Health.

Este artigo nada mais é do que um exercício que busca analisar de forma comparativa aspectos da construção da identidade de grupos judaicos oriundos do Marrocos. Um grupo que iniciou sua imigração para a Amazônia atraído pelo Ciclo da Borracha (1860-1910), e o outro grupo de judeus marroquinos que imigraram para Israel em 1950, vítimas das retaliações dos países árabes depois da criação do Estado de Israel. Por meio da análise da cerimônia pré-nupcial da hena, que é largamente adotada pelos judeus oriundos de países árabes, onde os noivos e seus convidados têm suas mãos adornadas com tintura de hena para afugentar o mau-olhado, teremos a possibilidade de vislumbrar a posição controvertida deste ritual em relação ao judaísmo rabínico, e como estas duas identidades judaico-marroquinas são construídas, atualizadas, e como esta cerimônia ajuda a demarcar a pertença étnica dos judeus marroquinos na sociedade israelense em relação a outras identidades judaicas, ou, ainda, como esta cerimônia, que já havia sido esquecida, foi resgatada na comunidade judaico-marroquina de Belém do Pará, como mais um dos sinais diacríticos formadores da identidade dos judeus marroquinos da Amazônia.

Uppsatsens syfte var att undersöka om begreppet Hen kan fylla en funktion i skolans jämställdhetsarbete. Jag har genomfört både kvalitativa och kvantitativa studier genom tre djupdykningar, en enkätundersökning som verksamma lärare svarade på, tre semistrukturerade intervjuer med informanter som främst representerar ett akademiskt perspektiv samt en textanalys från ett kapitel av en lärobok. Resultatet har jag teoretiserat genom Hirdmans begrepp det stereotypa genuskontraktet, Butlers teori om performativitet och genom den binära genusuppdelningens betydelse i genusordningen samt ställt resultatet i relation till tidigare forskning. Resultatet av teoretiseringen pekar i stor utsträckning på att de verksamma lärarna ser ett problem med det stereotypa genuskontraktet samt performativitet, men inte den binära genusuppdelningen. Informanterna såg problem med alla dessa begrepp då de är en del av genusordningen. I textanalysen framkom att läromedlet inte stämde överens med skolans uppdrag, att aktivt motarbeta traditionella könsmönster, då texten agerade konserverande i samtliga begrepp. Slutsatsen av uppsatsen är att eftersom genusordningen upprätthålls i skolan genom den binära genusordningen och performativa processer, har Hen en tydlig teoretisk funktion i skolan jämställdhetsarbete och kan därför vara gynnsamt att införa i skolans verksamhet.

The purpose of this study was to evaluate the effect of estradiol benzoate (EB) and progesterone/norgestomet on follicular dynamics of heifers aspirated every 7 d through synchronization of the follicular wave emergence in order to increase the number of follicles and quality of the recovered oocytes. Three experiments were designed in which crossbred Simmental x Nelore heifers were randomly divided into three groups, with all animals participating in all groups. In experiments 1 and 2, heifers were synchronized using a progestin implant for 7 d followed by a 150 µg im injection of d-Cloprostenol and aspiration of all ovarian follicles greater than 3 mm in diameter. In experiment 1 (n = 12), follicles from group 2X were aspirated twice a week with 4- and 3-day interval, and follicles from 1X and 1X-EB heifers were aspirated once a week. Heifers from group 1X-EB also received an im injection of 2 mg of EB immediately after OPU. In experiment 2 (n= 12), all heifers were aspirated once a week. Heifers from 0EB group did not receive EB, and from 2EB and 5EB received 2 mg and 5 mg of EB immediately after OPU. In experiment 3 (n = 15), heifers were synchronized with 2 mg EB and progesterone intravaginal implant (DIB) for seven d followed by an im PGF2_ injection. On day 4 of the subsequent estrous cycle, heifers received a DIB and had all ovarian follicles larger than 3 mm in diameter aspirated, followed by a PGF2_ injection on day seven. Heifers in groups 0h-EB (n = 4), -12h-EB (n = 6) and -24h-EB (n = 5) received 2 mg of EB immediately after OPU and twelve and twenty four h before, respectively. The semen, media used and culture conditions were equal for all groups. Ultrasound evaluations of number of follicles greater than 3 mm in diameter and size of the largest follicle at the time of OPU were performed. All recovered oocytes were in vitro matured and fertilized (D0). Cleavage rate on D2 and blastocyst production on D7 was evaluated. During a 7-day period, daily measurement of the size of the greatest follicle was performed by ultrasonography, and daily blood collection was done for evaluation of serum FSH concentrations. Although the use of EB in association with a norgestomet/progesterone implant seven d prior to OPU have altered follicular wave profile and FSH concentration, it was not able to efficiently synchronize the emergence of follicular wave and follicular deviation. Moreover, it was not enough to improve number and quality of the recovered oocytes. This study failed to demonstrate a positive effect of OPU earlier after wave emergence, when the effect of dominance should be less pronounced, on IVP in bovine. Moreover, the use of EB in association with a progesterone implant 12 and 24 h prior to OPU compromised the in vitro embryo production in a program of OPU with a 7 d interval between sessions.O objetivo deste estudo foi avaliar o efeito de benzoato de estradiol (BE) e progesterona/norgestomet sobre a dinâmica folicular de novilhas aspiradas a cada sete dias, sincronizando a emergência da onda folicular para aumentar o número de folículos e qualidade dos ovócitos. Em três experimentos, novilhas meio sangue Simental x Nelore foram divididas aleatoriamente em três tratamentos, com todos os animais participando de todos os tratamentos. Nos experimentos 1 e 2, as novilhas foram sincronizadas com implante de progesterona/progestágeno por 7 d seguido da administração im de 150 µg de d-Cloprostenol e aspiração de todos os folículos maiores que 3 mm de diâmetro. No Experimento 1 (n=12), os folículos das novilhas do tratamento 2X foram aspirados duas vezes por semana, com intervalo de 3 e 4 d, e os das novilhas do tratamento 1X e 1X-BE uma vez por semana. As novilhas do tratamento 1X-BE receberam 2 mg de BE im após a aspiração. No Experimento 2 (n = 12), as novilhas do tratamento NBE não receberam BE, e as dos tratamentos 2BE e 5BE receberam 2 mg e 5 mg após a aspiração. No Experimento 3 (n = 15), as novilhas foram sincronizadas com 2 mg de BE e implante intravaginal de progesterona (DIB) por sete dias, seguido de administração de PGF2_. No dia quatro do ciclo estral subseqüente, as novilhas receberam DIB e tiveram todos os folículos maiores que 3 mm de diâmetro aspirados, seguido da administração de PGF2_ no dia sete. As novilhas do tratamento 0h-BE (n= 4), -12h-BE (n = 6) e -24h-BE (n = 5) receberam 2 mg de BE imediatamente após a aspiração, doze e vinte e quatro horas antes, respectivamente. O sêmen, meios utilizados e as condições de cultivo foram iguais para todos os tratamentos. O número de folículos maior que 3 mm e o tamanho do maior folículo foram avaliados por ultra-sonografia no momento da aspiração folicular. Todos os ovócitos aspirados foram maturados e fecundados in vitro (D0), com a taxa de clivagem e a taxa de blastocisto avaliadas no D2 e D7, respectivamente. Durante uma semana foi realizada, diariamente, a mensuração do tamanho do maior folículo, por ultra-sonografia, e coletado sangue para a quantificação da concentração de FSH. Embora o uso de 2 mg de BE associado a progestágeno/progesterona tenha alterado o padrão de crescimento folicular e a concentração de FSH, não foi capaz de sincronizar eficientemente a emergência da onda e o desvio folicular, além de não aumentar o número e a qualidade dos ovócitos recuperados. Este estudo falhou em mostrar o efeito positivo da aspiração folicular logo após a emergência da onda folicular, quando o efeito da dominância seria menos evidente, sobre a produção in vitro de embriões bovinos. Além disso, o uso de BE associado a um dispositivo de progesterona, 12 h ou 24 h antes da aspiração folicular, prejudicou a produção de embriões in vitro, em um programa de aspiração com intervalo de sete dias entre sessões.

To evaluate the effect of different lighting programs on performance, feed intake at each six hours, economic aspects, carcass characteristics and antibodies production to Newcastle disease of broiler chickens an experiment was conducted with 840 young males chicks of the Cobb-500 lineage. The treatments defined according to the photoperiod were: 23L 23 hours of light and 1 hour of darkness from 1 to 45 days old; CRES 23 hours of light from 1 to 7 days old, without artificial light during the 8
and 21 days old, 14 hours of light from 22 to 28 days old, 18 hours of light from 29 to 35 days old and 23 hours of light from 35 to the 45 days old; 16L 16 hours of light from 1 to 45 days old and the NAT program, without artificial light during all the raising period. The poultry was located in an experimental poultry house, 11,60 birds for m2. The lighting intensity at the birds level was of 20 lux during all raising period that was from 1 to 45 days of age. The rations used were the same and offered at pleasure. The statistical design was the complete randomized divided in four treatments with six repetitions of 35 birds each. Analysis of variance with mean separation was made using SNK´s multiple range test for
performance, carcass characteristics, economic aspects and immunological response. Broiler chickens of CRES lighting program presented higher body weight (p<0,05) than birds of the others lighting programs that were similar between then (p>0,05). The feed intake of the birds of the CRES lighting program was higher than the birds of the 23L and NAT (p<0,05) and similar to the 16L treatment (p>0,05). Feed
conversion was not observed differences between treatments (p>0,05). The livability was higher in birds of the NAT lighting program than the 23L lighting program (p<0,05) and similar to the others treatments (p>0,05). Feed intake during 24 hours period was not observed differences between treatments at 27 days of age (p>0,05). Feed intake during 24 hours period at 34 days of age was higher in the 16L treatment than the others treatments (p<0,05) that were similar between then (p>0,05). The carcass, foot, head, abdominal fat, liver, heart and gut yield were not observed differences between treatments (p>0,05). The birds of the 23L lighting program presented breast muscle higher than the others treatments (p<0,05). The cost of the broiler kilogram was not observed differences between treatments (p>0,05). The antibody levels against Newcastle disease were not observed differences between treatments (p>0,05).Para avaliar os efeitos dos programas de luz sobre o desempenho, consumo de ração a cada seis horas aos 27 e 34 dias de idade, aspectos econômicos, rendimentos de abate e resposta à vacinação contra Newcastle foram utilizados 840 pintos machos da linhagem Cobb-500. Os tratamentos, definidos pelos períodos de luminosidade diária foram os seguintes: 23L quase contínua 23 horas de luz e uma hora de escuro do primeiro aos 45 dias de idade das aves; CRES 23 horas de luz até os 7 dias de idade, luz natural dos 8 aos 21 dias de idade, 14 horas de luz dos 22 aos 28 dias de idade, 18 horas de luz dos 29 aos 35 dias e 23 horas de luz dos 36 dias ao abate; 16L 16 horas de luz e 8 horas de escuro do primeiro aos 45 dias de idade e o programa NAT sem suplementação de luz artificial durante todo o período de criação. As aves foram alojadas em galpão experimental sendo a densidade de 11,60 aves/m2. O nível de iluminamento na altura das aves foi de 20 lux durante todo o período de criação que foi de 1 a 45 dias de idade. As rações utilizadas foram as mesmas para todas as aves e oferecidas à vontade. O delineamento experimental utilizado foi inteiramente ao acaso, com 4 tratamentos, 6 repetições de 35 aves. As diferenças entre as médias foram comparadas pelo teste de Student-Newman-Keuls (SNK) para desempenho, consumo, aspectos econômicos, rendimentos de abate e sorologia para detecção de anticorpos contra a doença de Newcastle. As aves submetidas ao programa de luz CRES apresentaram peso vivo superior quando comparado aos demais tratamentos (p<0,05), os quais apresentaram resultados semelhantes aos 45 dias de idade (p>0,05). O consumo de ração também foi superior nas aves do tratamento CRES quando comparado aos tratamentos 23L e NAT (p<0,05), e semelhante ao tratamento 16L (p>0,05). A conversão alimentar não foi influenciada pelos tratamentos (p>0,05). A viabilidade das aves do tratamento NAT foi superior em relação às aves do tratamento 23L (p<0,05) e semelhante aos demais tratamentos (p>0,05) aos 45 dias de idade. O consumo no período de 24 horas não foi influenciado pelos tratamentos aos 27 dias de idade (p>0,05). Aos 34 dias de idade, as aves do tratamento 16L apresentaram consumo superior às aves dos demais tratamentos (p<0,05), as quais apresentaram consumos semelhantes entre si (p>0,05). Os rendimentos de carcaça, pés, cabeça+pescoço, gordura abdominal, dorso, fígado, coração e intestinos não foram influenciados pelos tratamentos (p>0,05). As aves do tratamento 23L apresentaram rendimento de peito superior aos demais tratamentos (p<0,05). O custo do kg de frango não foi influenciado pelos tratamentos (p>0,05). Os títulos geométricos médios de anticorpos contra a doença de Newcastle não foram influenciados pelos tratamentos (p>0,05).

The aim of this study was to evaluate the application of a strategic control program of Amblyomma cajennense in equines, in the city of Palma, MG. Before the implantation of the program the parasitic loads of the A. cajennense and Anocentor nitens were observed, monthly, in the period from October of 2003 to March of 2004, in the same period of the following year the comparative analyses were carried. The acaricide treatments were carried to each seven days and divided in two batteries: the first one beginning in April of 2004, composed of eight treatments and second beginning in July of 2004, composed of five treatments, respectively, aiming to reach the larvae and nymphs of the A. cajennense. The chemical base used was pyrethroid - cypermethrin 0.015%, to bathe the equines. Clinical and hematological aspects (hemogram and serum biochemical) of the equines were analyzed before the control program. Also the effect of the program destined to the control of the A. cajennense on the population of A. nitens was observed. After the control program had a reduction of 44.85% of adults A. cajennense of October of 2004 to March 2005, and 59.74%, in February and March of 2005. The results of the clinical and hematological examinations of the equines had not evidenced alterations undesirable, but the improvement in some hemogram parameters. However the acaricide treatments had not determined significant reduction of the parasitic load of A. nitens in the equines. The control program revealed effective and safe for the control of the A. cajennense in the equines. However, it was not possible to carry through all the stages of the initial planning, once the study was carried on a commercial property, searched to define some critical points for the implantation of this type of technology in field situations. The interference was evidenced of the management model and structure of the agricultural company with the operational and technical aspects of the proposal of control of the tick, factors that can be determinant in the degree of success of the sanitary control. The permanence of the levels of infestation for A. nitens can be by no application of acaricide in nasal diverticulums of the equines, since this is an important site of parasitism of A. nitens in equines, however theres no compatible methods or acaricide formulations with the particularities of this anatomical structure.Avaliou-se a aplicação de um programa de controle estratégico de Amblyomma cajennense em eqüinos, no município de Palma, Minas Gerais. Antes da implantação do programa foram observadas as cargas parasitárias de A. cajennense e Anocentor nitens, mensalmente, no período de outubro de 2003 a março de 2004 e no mesmo período do ano seguinte foram realizadas as observações comparativas. Os tratamentos carrapaticidas foram realizados a cada sete dias e divididos em dois módulos: o primeiro com início em abril de 2004, composto de oito banhos e o segundo com início em julho de 2004, composto de cinco banhos, respectivamente, visando atingir as larvas e ninfas de A. cajennense. Empregou-se a base química piretróide - cipermetrina 0,015%, para banhar os eqüinos. Foram analisados aspectos clínicos e hematológicos (hemograma e bioquímica sérica) dos eqüinos perante o programa de controle. Também foram observados os efeitos do programa destinado ao controle do A. cajennense sobre a população de A. nitens. Após o programa de controle houve uma redução de 44,85% de adultos de A. cajennense no período de outubro de 2004 a março 2005, e de 59,74%, em fevereiro e março de 2005 em relação ao período anterior. Os resultados dos exames clínicos e hematológicos dos eqüinos não evidenciaram alterações. Observou-se a melhora em alguns parâmetros do hemograma em função das condições de saúde dos animais após o controle do carrapato. Porém os banhos carrapaticidas não determinaram redução significativa da carga parasitária de A. nitens nos eqüinos. O programa de controle mostrou-se efetivo para o controle do A. cajennense e seguro para os animais. No entanto, não foi possível realizar todas as etapas do planejamento inicial, uma vez que, o estudo foi realizado em uma propriedade comercial, contudo, buscou-se definir alguns pontos críticos para a implementação deste tipo de tecnologia em situações de campo. Puderam-se evidenciar a interferência do modelo de gestão e estrutura da empresa rural com os aspectos técnicos e operacionais da proposta de controle do carrapato, fatores que podem ser determinantes no grau de sucesso do controle sanitário. A permanência dos níveis de infestação por A. nitens, pode ser devida, a não aplicação do produto carrapaticida no divertículo nasal dos animais, pois este é um importante sítio de parasitismo de A. nitens em eqüinos, visto que não existem métodos ou formulações carrapaticidas compatíveis, técnica e operacionalmente, com as particularidades desta estrutura anatômica.

We develop a model to evaluate the effects of prednisone when applied at different time intervals after moderate and acute spinal cord injury. A pilot study using 10 Rattus novergicus allowed us to define a spinal cord injury protocol as 50.5g applied during five minutes with estereotoxic equipment. Later 25 rats were submitted to this protocol and randomly divided into five treatment groups: one group received placebo 8 hours after injury and the remaining four groups received prednisone eight, 24, 48 and 120 hours after injury. Prednisone was applied at 2 mg/Kg dosage during five days and progressively reduced until the 26th day. Animals were evaluated by motor capacity, proprioceptive positioning, searching ness reflex, inclined plan and sensibility to pain. Each rat was sacrificed 33 days after surgery for histopathology of the spinal cords that revealed degeneration of the rootlets, spinal cord necrosis and reactive gliosis, with no significant differences among treatment groups. Results for the various tests did not seem to be consistent and hence we could not conclude which treatment group was the best. Late administration of high dosages of prednisone to animals with acute spinal cord injury had no deleterious effects on neurological recoveryObjetivou-se desenvolver um modelo de trauma medular agudo e moderado, para avaliar o efeito da prednisona em diferentes tempos após esse trauma. Primeiramente foram utilizados 10 Rattus novergicus submetidos à compressão medular empregando-se um aparelho estereotáxico com diferentes pesos e tempos e padronizou-se a utilização de 50,5g por cinco minutos. Posteriormente, utilizou-se 25 ratos submetidos ao trauma proposto e divididos em cinco grupos de cinco. O grupo A recebeu placebo oito horas após o trauma; os grupos B, C, D e E receberam prednisona oito, 24, 48 e 120 horas após o trauma, respectivamente. A prednisona foi administrada na dose de 2mg/Kg, durante cinco dias com diminuição progressiva até o 26º dia. Os animais foram avaliados conforme a capacidade motora; posicionamento proprioceptivo; reflexo de localização; plano inclinado e sensibilidade dolorosa. Após 33 dias da cirurgia os animais foram sacrificados e, realizou-se a histopatologia das medulas espinhais onde constatou-se degeneração das raízes nervosas, necrose medular e reação glial, sem diferenças entre os grupos. Verificou-se falta de correlação entre os testes indicando que não houve um grupo superior. A utilização da prednisona na lesão medular não teve efeito diferenciado com o tempo e a administração tardia não foi prejudicial à recuperação neurológica.

The present study was conducted in order to analyze the possible risk factors involved the occurrence of Visceral Leishmaniasis (VL) in Belo Horizonte/MG, in 2006. It was made a case-Control study using questionnaire, images registration inside and outside of the affected dwellings and collection of canine blood. The sample was constituted by 82 human cases of VL occurred in 2004 and 164 controls (neighbors of the left and of the right of the cases). The nine regional administrative branch of the Town Hall of Belo Horizonte participated with residences in the study, in spite of not have aimed at geographical level of the disease. The collection of data of the cases happened with the relatives' participation, when it was not possible to do with the own cases. The biological material sample was sent to the laboratory of Leishmaniasis of the Veterinary School of UFMG for accomplishment of laboratory analysis (ELISA and IFAT). The interviewed population was characterized for being adult, with feminine sex slightly predominant. Larger occurrence of VL was noticed among children with age less or equal to 10 years. In relation to the dwellings, the risk factors show significant effect were: if there is a hen house in the propriety, humidity, garbage, fallow lands, If there is fruit or vegetable crop in the house, besides the presence of others animals such as rodents, birds and cats. Due to the low index of canine seropositivity, the dog presence in the residence was considered without statistical effect, which can be inferred a effective control of the animals soropositive for VL in areas with occurrence of human cases. The orientation of the people about the main VL information showed a potential protection, being estimated 2,24 times less likely of have a diseased among the people that have any knowledge about VL.Objetivou-se analisar os fatores de risco envolvidos na ocorrência de Leishmaniose Visceral (LV) em Belo Horizonte/MG, em 2006. Para tal, fez-se estudo de caso-controle por meio de entrevistas domiciliares, questionário semi-estrurado, registro de imagens do intra e peridomicílio e coleta de sangue canino. A amostra foi constituída por 82 casos humanos de LV ocorridos em 2004 e 164 controles (vizinhos da esquerda e da direita dos casos). As nove regionais administrativas de Belo Horizonte tiveram residências participantes no estudo, apesar desse não ter objetivado mapeamento geográfico da doença. A coleta de dados dos casos ocorreu com a participação de familiares, quando não foi possível fazê-la com os próprios acometidos. O material biológico coletado foi encaminhado para o laboratório de Leishmaniose da Escola de Veterinária da UFMG para realização de análises sorológicas (Ensaio Enzimático - ELISA e Reação de Imunofluorescência Indireta - RIFI). A população entrevistada se caracterizou por ser adulta, com discreto predomínio do sexo feminino. Notou-se maior acometimento da LV em crianças com idade inferior ou igual a 10 anos. Em relação às residências, os fatores de risco que se mostraram significativos foram: a existência de galinheiro, umidade, lixo, terrenos baldios, cultivo de plantas frutíferas e arborização ao redor do domicílio, além da presença de outros animais, tanto domésticos quanto silvestres, como roedores, pássaros e gatos. Devido ao baixo índice de soropositividade canina, a presença de cão na residência foi considerada sem significância estatística, o que sinaliza um controle efetivo dos animais soropositivos para LV em áreas com ocorrência de casos humanos da doença. A orientação das pessoas sobre as principais informações que abordam a doença mostrou potencial de proteção, sendo estimado um decréscimo no risco de ser acometido de 2,24 vezes para pessoas que detenham quaisquer conhecimentos sobre a LV.

The present work aimed to describing values and aspects that can serve as parameters of physiological reference for the hematology of the blue-fronted-parrot (Amazona aestiva - Psittacidae), as well as determining the occurrence of hemoparasites, in an established commercial breeder in Betim - Minas Gerais, Brazil. Fifty eight blue-fronted-parrot (Amazona aestiva) on captivity for at least three years, adults, of both sex and in adequate conditions of health were used. After an statistics analysis of the results, the following basic parameters were found (Mean + Standard Derivation): Erythrocytes (x106/mm3): 2,54 + 0,45; Hemoglobin (g/dL): 16,28 + 1,13; Hematocrit (%): 44,66 + 4,45; Mean corpuscular volume (µ3ou fL): 179,99 + 32,15; Mean corpuscular hemoglobin (µµg ou pg): 65,50 + 8,15; Mean corpuscular hemoglobin concentration (g/dL or %): 36.51 + 2,90; immature erythrocytes (x103/mm3): 32,06 + 1,85; Thrombocytes (x 103/mm3): 16,61 + 7,45; Leukocytes (x 103/mm3): 7,01 + 4,15; Heterphils (x 103/mm3): 3,40 + 2,05; Lymphocytes (x 103/mm3): 3,37 + 2,83; Monocytes (x 103/mm3): 0,16 + 0,16; Basophils (x 103/mm3): 0,08 + 0,09; Eosinophils (x103/mm3): 0,02 + 0,05; immature granulocytes (x /mm3): 37,95 + 84,17. Parameters for subpopulations of immature erythrocytes and immature granulocytes in the peripheral blood, as well as morphologic characteristics of the subpopulations of leukocytes and thrombocytes were also evaluated. The occurrence of Plasmodium sp. in peripheral blood occurred in 29,31% of birds, and the parasitemy was 0,031% + 0,031%. Significant differences had not been observed between: sex; clinical and reproductive parameters. There was no statistical difference on hematological parameters between both groups (with or without Plasmodium sp.), except for the parameters of counting of juvenile polychromatic erythrocytes and advanced polychromatic erythrocytes (P = 0,004 and 0,025 respectively).O presente trabalho objetivou descrever valores e aspectos que possam servir como parâmetros de referência fisiológica para a hematologia do papagaio-verdadeiro (Amazona aestiva - Psittacidae), bem como determinar a ocorrência de hemoparasitoses em um criatório comercial estabelecido em Betim Minas Gerais, Brasil. Para tanto utilizaram-se 58 (cinqüenta e oito) papagaios-verdadeiros (A. aestiva) cativos a pelo menos três anos, adultos, de ambos os sexos e em condições adequadas de saúde. Após analises estatísticas dos dados, foram obtidos os seguintes parâmetros fundamentais (Média + Desvio Padrão): Hemácias (x 106/mm3): 2,54 + 0,45; Hemoglobina (g/dL): 16,28 + 1,13; Hematócrito (%): 44,66 + 4,45; Volume corpuscular médio (µm3 ou fL): 179,99 + 32,15; Hemoglobina corpuscular média (µµg ou pg): 65,50 + 8,15; Concentração hemoglobina corpuscular média (g/dL ou %): 36,51 + 2,90; Eritrócitos imaturos (x 103/mm3): 32,06 + 1,85; Trombócitos (x 103/mm3): 16,61 + 7,45; Leucócitos (x103/mm3): 7,01 + 4,15; Heterófilos (x 103/mm3): 3,40 + 2,05; Linfócitos (x 103/mm3): 3,37 + 2,83; Monócitos (x 103/mm3): 0,16 + 0,16; Basófilos (x 103/mm3): 0,08 + 0,09; Eosinófilos (x 103/mm3): 0,02 + 0,05; Granuloblastos (x /mm3): 37,95 + 84,17. Também foram avaliados parâmetros referenciais para subpopulações de eritroblastos e granuloblastos no sangue periférico, bem como características morfológicas das subpopulações de leucócitos e trombócitos. Neste estudo, observou-se a ocorrência de 29,31% de aves hemoparasitadas por Plasmodium sp. com parasitemia de 0,031% + 0,031%. Não foram observadas diferenças significantes entre: sexos; parâmetros clínicos e reprodutivos. Quanto ao hemograma, não se evidenciou diferença relevante nos parâmetros hematológicos entre sexos, exceto para os parâmetros de contagem dos eritrócitos policromáticos jovens e eritrócitos policromáticos avançados (P = 0,004 e 0,025 respectivamente).

Norstedt, Karin (2020). Hela barnet hela dagen, Om fritidshemspersonalens tillgång till specialpedagogiskt stöd. Specialpedagogprogrammet, Institutionen för skolutveckling och ledarskap, Lärande och samhälle, Malmö universitet, 90 hp. Förväntat kunskapsbidrag Det här arbetet väntades kunna bidra till att det forskas mer kring specialpedagogik på fritidshemmet. Att belysa i vilken omfattning en del personal i fritidshemmet upplevde stöd, ämnade studien ge en inblick i ämnet. Det här arbetet kan bidra med insikt och kunskap kring vikten av att det specialpedagogiska stödet till lärare ska fördelas efter behov även för personal på fritidshemmen. För specialpedagogen kan arbetet bidra till att belysa vikten av att fritidshemmet inkluderas i arbetet för barn i behov av särskilt stöd Syfte och frågeställningar Syftet med undersökningen är att ta reda på i vilken utsträckning personal i fritidshemmen har tillgång till specialpedagogiskt stöd samt hur detta stöd ser ut utifrån givna kategorier. Frågeställning Hur upplever verksamma inom fritidshemmet omfattning och innehåll i specialpedagogiskt stöd Vilket stöd ges och vilket stöd efterfrågas? Teori Den teoretiska utgångspunkten var Bronfenbrenners (1979) miljöekologiska systemteori som menar att delarna inte kan verka var för sig utan måste ses ur ett helhetsperspektiv. I sammanhanget är fritidshemmet en del av barnets hela skoltid dvs. helheten. Att bearbeta och analysera utifrån denna teori fyllde sitt syfte väl gällande att se delarna som en del av helheten. Teorin bearbetade materialet utifrån och in, där Bronfenbrenners (1979) ekologiska systemteori startar med makronivån som innefattade skollag och politik, värderingar och normer. Sedan följer exonivå som bland annat innefattar skolans organisation, sjukvård och andra organisationer som kan påverka individen indirekt. Mesonivån användes som ett sätt att se på samverkan mellan skola och hem och dess kunskap om varandra. Mikronivån är individen och den miljö och relationer den möter under dagen i skolans lokaler, dvs fritids-skola-fritids. Metod För att ta reda på hur många anställda (lärare i fritidshem, fritidspedagog och annan utbildning) i fritidshemmet som upplevde ett specialpedagogiskt stöd var kvantitativ enkätundersökning den metod som lämpade sig bäst. I enkäten användes slutna frågor för att kunna besvara frågeställningen. Detta sammanställdes i olika tabeller och figurer för att få en uppfattning kring stödet. Ett fritextsvar fanns under en del frågor och som resulterade i en djupare inblick i hur respondenterna upplevde stödet eller icke stödet. Resultat Resultatet visade att det finns en signifikant skillnad i upplevelsen av specialpedagogiskt stöd. Lite mer än 2/3 upplevde ett stöd som inte kan ses som tillräckligt (Ja, men inte i den utsträckning jag önskar eller Nej). Resultatet visade att det stödet som efterfrågas främst är handledning och stöttning kring lärmiljön. Detta gav indikationer på att det måste ske förändringar i systemet som skapar förutsättningar för specialpedagoger och verksamma i fritidshemmet att utveckla och vidmakthålla en verksamhet som lever upp till skollagen Specialpedagogiska implikationer Specialpedagogens uppgift är att se barnet som en helhet, dvs allt som på något sätt berör barnet, och det är helheten som ska ligga till grund för det stöd som ges. Det betyder att barnets kunskapsutveckling, sociala utveckling och hälsa är delar av helheten. Dessa delar existerar från tidig morgonfritids till lektionstid och till eftermiddagsfritids. Genom att handleda och använda fritidshemmens kunskap kring aspekter som direkt eller indirekt kan påverka elevens helhet, kan specialpedagogen vara med och förändra, stötta och anpassa även fritidshemmets verksamhet. Specialpedagogen måste ges förutsättningen till samverkan med alla delar och dessa förutsättningar är en del av huvudmännens uppdrag. Specialpedagogiken och det stöd specialpedagogen kan ge, bör innefatta fritidshemmet.

The aim of this study was to determine the eggs and eggshell quality of organic laying hens at different stages of the one-year production cycle. Based on the results of these studies, it can be concluded that the organic eggs of 24-week-old Isa Brown layers had lower weight and a higher shape index than the eggs of 48- and 72-week-old hens. On the other hand, the eggs of 24- and 48-week-old laying hens had a higher albumen height and Haugh units, and less colored yolks compared to the eggs of 72-week-old hens. In terms of eggshell quality, 24-week-old hen eggs had a higher proportion, thickness and breaking strength and less shell deformation compared to 48- and 72-week-old hen eggs.

Full textAbstract:
The present paper describes the latest development of an Expert System for the design and optimization of Heat Exchange Networks (HEN). The code described herein, HENEA (acronym for Heat Exchanger Network Expert Assistant) is a Knowledge Based System capable of interacting with a Process Engineer to generate an optimal configuration for a HEN under several different objective functions. Contrary to most of the currently available methods, the code is able to produce such solutions by making explicit use of a set of Second Law Analysis criteria and of some of the basic principles of the “Pinch Method”. With respect to the previous version, HENEA now includes an additional application, “HEN-SPLIT” that accounts for the possibility of splitting one or more of the participating streams according with a general “minimal entropy generation” criterion. In its present version, HENEA can be used both for process design (new HEN) and for process structural optimization (retrofit problems). The optimization procedure is based on Sama’s “Second Law Insight Method” and is directly and explicitly finalized to the reduction of the global entropy generation. The code is also endowed with a cost calculations utility, and can be thus employed to search for the optimum using two alternative optimization criteria: it generates in fact both a Maximum Energy Recovery (MER) and Minimum Exchange Area configuration (MCC, Minimum Capital Cost). Since the code is though intended for practical industrial use, and it is well known that a thermodynamically optimal configuration is not always the “most convenient” one from an engineering point of view, HENEA presents to the user also a certain number of additional sub-optimal configurations. An interactive graphic user interface makes HENEA very user-friendly: furthermore, the user can (indirectly) interrogate HENEA about its choices and understand the underlying physic in an unambiguous and immediate way. Several tests conducted on some of the available benchmarks have proven that the solutions generated by HENEA are always comparable to those produced by other optimization criteria (Pinch Method or Second Law method): in fact, for large problems (many participating streams, several splittings) they are often better than those obtained with its competitors.

Full textAbstract:
Spent hens, a poultry by-product, have little economic value for processing due to poor meat quality and low yield. In North America alone, 150 million spent hens are produced every year which are either end up in landfill or burnt. However, there are concerns over disposal of spent hens; therefore, it is pertinent to find out alternative uses that are environmentally friendly. On the other hand, single-use plastic packaging is leading to a global environmental crisis. The development of hybrid bionanocomposite films from spent hen proteins using cellulose nanocrystals (CNCs) is a viable option for food packaging applications. In this study, proteins were harvested from spent hen using alkali aided extraction method. To develop protein derived bionanocomposite films, glycerol was used as a plasticizer and chitosan as a cross-linker agent. Furthermore, cellulose nanocrystals (1,3,5%) were incorporated into the proteins/glycerol/chitosan mixture and sonicated it for an hour. Finally, mixture was transformed into food packaging films using compression molding and characterized using FTIR, XRD, TEM, DMA, DSC and TGA.The results indicated that alkali aided method provided excellent proteins recovery yield (74%) and percentage purity (96%) from spent hen. The physicochemical analysis showed an improvement in the thermal, mechanical, and barrier properties of the prepared bionanocomposite films. A greater enhancement in mechanical strength (2.65± 0.50 to 8.48±0.98 MPa) of CNCs derived films was observed as compared to films without nanoparticles. Transmission electron microscopy images confirmed the dispersion of CNCs into the protein polymeric chains which resulted in good exfoliation/intercalation of CNCs and improved the overall properties of the films.The above results suggested that spent hen proteins have great future potential to develop protein/CNCs hybrid bionanocomposite films with improved functional properties for food packaging applications. The petro-based plastic environmental impacts can be reduced with the development of these environmentally benign bionanocomposite films.

Full textAbstract:
The synthesis of heat exchanger networks (HENs) is one of the most studied problems in process synthesis, because a high level of integration of the internal heat transfer is necessary to reduce both primary energy consumption and total costs. This work develops a methodology for the multi-objective optimization of HEN synthesis. A two-level hybrid algorithm operating on a population of candidate HEN topologies is proposed to search for the best tradeoffs between the maximization of energy recovery and the minimization of total HEN costs. The advantages deriving from graph representations of a HEN are fully exploited in order to handle topologies with arbitrary complexity and to simplify the optimization procedure required to evaluate the objective functions for a given topology. The Aromatics Plant problem, a well-known test case in the literature about HEN synthesis, is used as a test case to show the potentialities of the proposed methodology.

Full textAbstract:
Abstract This paper presents a novel method for the design of “optimal” (or quasi-optimal) HEN. The method consists of an Expert System (“ES”) based on a small number of powerful and strongly selective heuristic rules. The important contribution of this study does not lie in the formulation of the rules, that have been adapted from the existing literature, but in their expression as logical propositions, and in their subsequent implementation in a prototype ES that performs interactively with the user. It is not unusual to find chemical processes with as many as 100 interacting streams, and even simple thermal processes, excluding refineries and chemical plants, contain at least a 10-streams-HEN: hence the high demand for an “automatic” (in some sense) Design Procedure that may conveniently be adapted to design-and-optimisation problems. Pinch Technology (“PT”), at present the almost universally adopted design procedure, is very successful in most types of applications (except in cases where mechanical and thermal power must be optimised concurrently), but it constitutes an operative tool, and does not improve its user’s comprehension of the problem: it assumes, rather, that the user is already familiar with the design of HEN. The approach we present in this paper is entirely different: we do not “mask” the thermodynamic and thermo-economic principles that guide the engineer in the path towards the “optimal” HEN configuration, and do not allow concerns about “user friendliness” to impair the necessary participation of the user to the HEN synthesis procedure. In fact, though our ES (which we prefer to call “Expert Assistant”, to underline its peculiarity of constantly interacting with the user) is still lacking many of the capabilities that a good designer possesses, the underlying procedure is, unlike any of the other existing Design-and-Optimisation Procedures, entirely inspectable by the user for what its decision-making rules are concerned. It can be interrogated about its decision making, so that the logical path followed from the design data to the final solution can be inspected at will, and it can be used to directly compare different alternatives in a logically systematic fashion. The paper begins with a brief review of the HEN design problem, followed by a critical discussion of the heuristic rules that form the basis for the Inference Engine of the Expert System. The formalisation of these rules into logical propositions suitable for Knowledge Based Methods is then presented, and the resulting macrocode developed. As a preliminary validation, two examples of application of the code (named Heat Exchanger Network Expert Assistant, HENEA for short) are presented and discussed: since both cases have published, and their “optimal” solutions are known, the performance of HENEA can be assessed by comparison.

Full textAbstract:
In most finite-element-analysis codes, accuracy is achieved through the use of the hexahedron hexa-20 elements (a node at each of the 8 corners and 12 edges of a brick element). Unfortunately, without an additional node in the center of each of the element’s 6 faces, nor in the center of the hexa, the hexa-20 elements are not fully quadratic such that its truncation error remains at h2(0), the same as the error of a hexa-8 element formulation. To achieve an accuracy with a truncation error of h3(0), we need the fully-quadratic hexa-27 formulation. A competitor of the hexa-27 element in the early days was the so-called serendipity cubic hexa-32 solid elements (see Ahmad, Irons, and Zienkiewicz, Int. J. Numer. Methods in Eng., 2:419–451 (1970) [1]). The hexa-32 elements, unfortunately, also suffer from the same lack of accuracy syndrome as the hexa20’s. In this paper, we investigate the accuracy of various elements described in the literature including the fully quadratic hexa-27 elements to a shell problem of interest to the pressure vessels and piping community, viz. the shell-element-based analysis of a barrel vault. Significance of the highly accurate hexa-27 formulation and a comparison of its results with similar solutions using ABAQUS hexa-8, and hexa-20 elements, are presented and discussed. Guidelines are proposed for selection of better elements.

Full textAbstract:
This brief explains youth perceptions of COVID-19 vaccination and outlines key considerations for engaging with and building trust among young people living in Ealing, London. Within the category of ‘young people,’ there are differences in vaccination based on age and ethnicity. This brief is based on research, including a review of the literature and in-depth interviews and focus groups with 62 youth across Ealing to contextualise youth perspectives of COVID-19 vaccination and highlight themes of trust/distrust. We contribute ethnographic and participatory evidence to quantitative evaluations of vaccine roll-out. Key considerations for addressing youth distrust regarding the COVID-19 vaccine are presented, followed by additional regional context. This work builds on a previous SSHAP brief on vaccine equity in Ealing. This brief was produced by SSHAP in collaboration with partners in Ealing. It was authored by Megan Schmidt-Sane (IDS), Tabitha Hrynick (IDS), Jillian Schulte (Case Western Reserve University), Charlie Forgacz-Cooper (Youth Advisory Board), and Santiago Ripoll (IDS), in collaboration with Steve Curtis (Ealing Council), Hena Gooroochurn (Ealing Council), Bollo Brook Youth Centre, and Janpal Basran (Southall Community Alliance), and reviews by Helen Castledine (Ealing Public Health), Elizabeth Storer (LSE) and Annie Wilkinson (IDS). The research was funded through the British Academy COVID-19 Recovery: USA and UK fund (CRUSA210022). Research was based at the Institute of Development Studies.

The aim of the research is to identify the elements of the psycholinguistic image of the main antagonist Hela in the superhero film Thor: Ragnarok based on the Marvel Comics and directed by Taika Waititi (2017). The task consists of two stages, at the first of which I identify the psychological characteristics of the character to determine to which of the archetypes Hela belongs. As the basis, I take the classification of film archetypes by V. Schmidt. At the second stage, I distinguish the speech peculiarities of the character that reflect her psychological image.

Hazards, Exposure and Vulnerability in Indonesia: A risk assessment across regions and provinces to inform the development of an Adaptive Social Protection Road Map. United Nations University - Institute for Environment and Human Security, March 2022. http://dx.doi.org/10.53324/uvrd1447.
Full textAbstract:
Risk induced by natural hazards and climate change has been accelerating worldwide, leading to adverse impacts on communities' well-being. Dealing with this risk is increasingly complex and requires cross-sectoral action. Adaptive Social Protection (ASP) has emerged as a promising approach to strengthen the resilience of communities by integrating Social Protection (SP), Disaster Risk Management (DRM) and Climate Change Adaptation (CCA) efforts. To inform this integration and thereby support the development of a functional ASP approach, the identification and provision of relevant data and information are vital. In this context, risk assessments are crucial as they establish the groundwork for the design of effective ASP interventions. However, despite the importance of risk information for ASP and the abundance of sectoral assessments, there is not yet a comprehensive risk assessment approach, a reality that also applies to Indonesia. Although the country is one of the international pioneers of the concept and has enshrined ASP at the highest national level in its development plans, this emphasis in policy and practice has been hampered by the absence of more unified assessment methods. The Hazard, Exposure and Vulnerability Assessment (HEVA) presented here takes a unique approach to develop such a cross-sectoral risk assessment and apply it throughout Indonesia. The HEVA brings together different risk understandings of key actors both internationally and domestically within SP, DRM and CCA, as well as identifying commonalities across sectors to establish a joint understanding. The HEVA not only considers risk as an overarching outcome but also focuses on its drivers, i.e. hazards, exposure and vulnerability, to identify why specific communities are at risk and thus customize ASP interventions. Subsequently, risks are assessed for Indonesia’s regions and provinces based on this cross-sectoral risk understanding. Secondary data has been acquired from various existing sectoral assessments conducted in Indonesia, and in total, data for 44 indicators has been compiled to calculate hazard, exposure and vulnerability levels for all 34 Indonesian provinces. Findings of the HEVA suggest that overall risk is high in Indonesia and no single province can be characterized as a low-risk area, demonstrating a strong relevance for ASP throughout the whole of the country. Papua, Maluku, and Central Sulawesi were identified as provinces with the highest overall risk in Indonesia. However, even Yogyakarta, which was identified as a comparatively low-risk province, still ranks among the ten most hazard-prone provinces in the country and has a demonstrated history of severe impact events. This also underlines that the composition of risk based on the interplay of hazard, exposure and vulnerability differs significantly among provinces. For example, in Papua and West Papua, vulnerability ranks as the highest in Indonesia, while hazard and exposure levels are comparatively low. In contrast, East Java and Central Java are among the highest hazard-prone provinces, while exposure and vulnerability are comparatively low. The results provide much more comprehensive insight than individual sectoral analyses can offer, facilitating the strategic development and implementation of targeted ASP interventions that address the respective key risk components. Based on lessons learned from the development and application of the HEVA approach, as well as from the retrieved results, the report provides recommendations relevant for policymakers, practitioners and researchers. First, recommendations regarding risk assessments for ASP are given, emphasizing the need to bring together sectoral understandings and to consider the interconnection of hazards, exposure and vulnerability, including their drivers and root causes, to assess current and future risk. It is also recommended to complement national level assessments with more specific local assessments. Secondly, recommendations regarding ASP option development in general are provided, including the importance of considering side effects of interventions, root causes of risks, the potential of nature-based solutions and barriers to implementation due to local capacities when designing ASP interventions. Third, recommendations regarding focal areas for ASP programmes are outlined for the case of Indonesia, such as prioritizing interventions in risk hotspots and areas characterized by high readiness for ASP solutions. At the same time, it is vital to leave no region behind as all provinces face risks that potentially jeopardize communities’ well-being.

Men för att ringa in begreppen lekfullhet och disciplin, behöver jag först ta er med till en lägenhet i Göteborg, närmare bestämt i övre Guldheden. Där, i en kökssoffa allra längst upp i hörnlägenheten med utsikt över hela staden, tillbringade jag en stor del av min uppväxt. Anledningen var att jag hade kommit till lite väl tidigt i mina föräldrars relation. De hade just tagit studenten – och det var stort – men sedan kom det ett hot mot den unga familjens klassresa. Och det hotet var jag. Därför ryckte min morfar och mormor ut, och hämtade mig till sin kökssoffa...

Full textAbstract:
The aim of the research is to identify the elements of the psycholinguistic image of the leading character in the dark fantasy adventure film Maleficent directed by Robert Stromberg (2014). The task consists of two stages, at the first of which I identify the psychological characteristics of the character to determine to which of the archetypes Maleficent belongs. As the basis, I take the classification of film archetypes by V. Schmidt. At the second stage, I distinguish the speech peculiarities of the character that reflex her psychological image. This paper explores 98 Maleficent’s turns of dialogues in the film. According to V. Schmidt’s classification, Maleficent belongs first to the Matriarch archetype and later in the plot to the Scorned Woman archetype. These archetypes are representations of the powerful goddess of marriage and fertility Hera, being respectively her heroic and villainous embodiments. There are several crucial characteristics revealed by speech elements.
