Sobre la crítica de Mumford al realismo nomológico

Resumen Stephen Mumford (2004) propone una alternativa al Realismo Nomológico que no requiere resignar los compromisos modales comúnmente asociados a posiciones realistas, un Realismo Sin Leyes (RSL) donde el peso de la modalidad no está puesto sobre las leyes sino sobre propiedades entendidas en términos de poderes y disposiciones. Las ventajas relativas del RSL dependen, sin embargo, de una serie de objeciones que presenta al RN. La principal de ellas es la que Mumford denomina el Dilema Central, según el cual el RN no es capaz de dar cuenta de cómo las leyes gobiernas sus instancias. En el presente trabajo me propongo mostrar que ni el Dilema Central ni el resto de los argumentos de Mumford contra el RN justifican su rechazo.

Understanding the Racial Nature of Police and Immigrant Relations In Finland. The Case of Africans in Turku

The focus of this study is to examine the role of police and immigrants’ relations, as less is known about this process in the country. The studies were approached in two different ways. Firstly, an attempt was made to examine how immigrants view their encounters with the police. Secondly, the studies explored how aware the police are of immigrants’ experiences in their various encounters and interactions on the street level. An ancillary aim of the studies is to clarify, analyse and discuss how prejudice and stereotypes can be tackled, thereby contributing to the general debate about racism and discrimination for better ethnic relations in the country. The data in which this analysis was based is on a group of adults (n=88) from the total of 120 Africans questioned for the entire study (n=45) police cadets and (n=6) serving police officers from Turku. The present thesis is a compilation of five articles. A summary of each article findings follows, as the same data was used in all five studies. In the first study, a theoretical model was developed to examine the perceived knowledge of bias by immigrants resulting from race, culture and belief. This was also an attempt to explore whether this knowledge was predetermined in my attempt to classify and discuss as well as analyse the factors that may be influencing immigrants’ allegations of unfair treatment by the police in Turku. The main finding shows that in the first paper there was ignorance and naivety on the part of the police in their attitudes towards the African immigrant’s prior experiences with the police, and this may probably have resulted from stereotypes or their lack of experience as well as prior training with immigrants where these kinds of experience are rampant in the country (Egharevba, 2003 and 2004a). In exploring what leads to stereotypes, a working definition is the assumption that is prevalent among some segments of the population, including the police, that Finland is a homogenous country by employing certain conducts and behaviour towards ethnic and immigrant groups in the country. This to my understanding is stereotype. Historically this was true, but today the social topography of the country is changing and becoming even more complex. It is true that, on linguistic grounds, the country is multilingual, as there are a few recognised national minority languages (Swedish, Sami and Russian) as well as a number of immigrant languages including English. Apparently it is vital for the police to have a line of communication open when addressing the problem associated with immigrants in the country. The second paper moved a step further by examining African immigrants’ understanding of human rights as well as what human rights violation means or entails in their views as a result of their experiences with the police, both in Finland and in their country of origin. This approach became essential during the course of the study, especially when the participants were completing the questionnaire (N=88), where volunteers were solicited for a later date for an in-depth interview with the author. Many of the respondents came from countries where human rights are not well protected and seldom discussed publicly, therefore understanding their views on the subject can help to explain why some of the immigrants are sceptical about coming forward to report cases of batteries and assaults to the police, or even their experiences of being monitored in shopping malls in their new home and the reason behind their low level of trust in public authorities in Finland. The study showed that knowledge of human rights is notably low among some of the participants. The study also found that female respondents were less aware of human rights when compared with their male counterparts. This has resulted in some of the male participants focussing more on their traditional ways of thinking by not realising that they are in a new country where there is equality in sexes and lack of respect on gender terms is not condoned. The third paper focussed on the respondents’ experiences with the police in Turku and tried to explore police attitudes towards African immigrant clients, in addition to the role stereotype plays in police views of different cultures and how these views have impacted on immigrants’ views of discriminatory policing in Turku. The data is the same throughout the entire studies (n=88), except that some few participants were interviewed for the third paper thirty-five persons. The results showed that there is some bias in mass-media reports on the immigrants’ issues, due to selective portrayal of biases without much investigation being carried out before jumping to conclusions, especially when the issues at stake involve an immigrant (Egharevba, 2005a; Egharevba, 2004a and 2004b). In this vein, there was an allegation that the police are even biased while investigating cases of theft, especially if the stolen property is owned by an immigrant (Egharevba, 2006a, Egharevba, 2006b). One vital observation from the respondents’ various comments was that race has meaning in their encounters and interaction with the police in the country. This result led the author to conclude that the relation between the police and immigrants is still a challenge, as there is rampant fear and distrust towards the police by some segments of the participating respondents in the study. In the fourth paper the focus was on examining the respondents’ view of the police, with special emphasis on race and culture as well as the respondents’ perspective on police behaviour in Turku. This is because race, as it was relayed to me in the study, is a significant predictor of police perception (Egharevba, 2005a; Egharevba and Hannikianen, 2005). It is a known scientific fact that inter-group racial attitudes are the representation of group competition and perceived threat to power and status (Group-position theory). According to Blumer (1958) a sense of group threat is an essential element for the emergence of racial prejudice. Consequently, it was essential that we explored the existing relationship between the respondents and the police in order to have an understanding of this concept. The result indicates some local and international contextual issues and assumptions that were of importance tackling prejudice and discrimination as it exists within the police in the country. Moreover, we have to also remember that, for years, many of these African immigrants have been on the receiving end of unjust law enforcement in their various countries of origin, which has resulted in many of them feeling inferior and distrustful of the police even in their own country of origin. While discussing the issues of cultural difference and how it affects policing, we must also keep in mind the socio-cultural background of the participants, their level of language proficiency and educational background. The research data analysed in this study also confirmed the difficulties associated with cultural misunderstandings in interpreting issues and how these misunderstandings have affected police and immigrant relations in Finland. Finally, the fifth paper focussed on cadets’ attitudes towards African immigrants as well as serving police officers’ interaction with African clients. Secondly, the police level of awareness of African immigrants’ distrustfulness of their profession was unclear. For this reason, my questions in this fifth study examined the experiences and attitudes of police cadets and serving police officers as well as those of African immigrants in understanding how to improve this relationship in the country. The data was based on (n=88) immigrant participants, (n=45) police cadets and 6 serving police officers from the Turku police department. The result suggests that there is distrust of the police in the respondents’ interaction; this tends to have galvanised a heightened tension resulting from the lack of language proficiency (Egharevba and White, 2007; Egharevba and Hannikainen, 2005, and Egharevba, 2006b) The result also shows that the allegation of immigrants as being belittled by the police stems from the misconceptions of both parties as well as the notion of stop and search by the police in Turku. All these factors were observed to have contributed to the alleged police evasiveness and the lack of regular contact between the respondents and the police in their dealings. In other words, the police have only had job-related contact with many of the participants in the present study. The results also demonstrated the complexities caused by the low level of education among some of the African immigrants in their understanding about the Finnish culture, norms and values in the country. Thus, the framework constructed in these studies embodies diversity in national culture as well as the need for a further research study with a greater number of respondents (both from the police and immigrant/majority groups), in order to explore the different role cultures play in immigrant and majority citizens’ understanding of police work.

DINÂMICA DOS ATRIBUTOS FÍSICO-QUÍMICOS E VARIA��ÃO SAZONAL DOS ESTOQUES DE CARBONO NO SOLO EM DIFERENTES FITOFISIONOMIAS DO PANTANAL NORTE MATO-GROSSENSE

O bioma Pantanal pode ser considerado um ambiente de hipersazonalidade, onde há um período de inunda��ão pronunciada seguido por extenso período seco com temperaturas muito elevadas. A diversidade de suas fitofisionomias ocasiona aportes de carbono para o solo em quantidade e qualidade distintas. Com esse foco, este trabalho teve por objetivo verificar o efeito do ciclo hidrológico do Pantanal (enchente, cheia, vazante e estiagem) sobre a dinâmica do estoque carbono orgânico do solo nas fitofisionomias de Cambarazal, de Floresta Ripária, de Cordilheira e de Espinheiral. Verificou-se que as fitofisionomias puderam ser separadas pela análise de componentes principais (ACP) em três grupos distintos, caracterizados pela reserva de nutrientes e pela acidez do solo. O estoque de carbono do solo está condicionado por fatores sazonais e igualmente dependentes da fitofisionomia local que ocorreram nas fitofisionomias que apresentaram maior nível de fertilidade natural, ou seja, respectivamente o Cambarazal e o Espinheiral. O maior teor de carbono foi observado no período de enchente, na maioria das fitofisionomias, e o menor estoque de carbono aconteceu no período de vazante (2008), após o período de anaerobiose em razão da enchente e antes que o período seco passasse a ser determinante.

Avalia��ão da exposição solar na intoxica��ão experimental por Brachiaria decumbens em ovinos

Foram utilizados 26 ovinos, entre 3 e 4 meses de idade, divididos em 3 grupos, provenientes de rebanhos que nunca tiveram contato com pastos de Brachiaria spp.. Dois grupos receberam Brachiaria decumbens no cocho diariamente ad libitum, sendo que um deles permaneceu em área com exposição solar (GS) e o outro foi mantido em baias cobertas protegidos do sol (GSB). O grupo controle (GC) foi também mantido em local com exposição solar e alimentado com feno de Cynodon dactylon e capim Pennisetum purpureum triturado. Todos os grupos receberam alimenta��ão em cochos e foram suplementados com 200g/dia/animal de ra��ão comercial para ovinos. Foi realizada a avalia��ão clínica diária dos ovinos e colhidas amostras duas vezes por semana para dosagem sérica de AST e GGT. Os animais que morreram foram submetidos a necropsia e em todos os ovinos sobreviventes foi realizada biópsia hepática no final do experimento. Três animais do grupo GS adoeceram e dois morreram. Um ovino do grupo GSB adoeceu e morreu. Não houve altera��ões clínicas nos ovinos controles. Os principais sinais clínicos observados nos animais que adoeceram foram apatia, emagrecimento, fotofobia, hiperemia e secreção ocular e icterícia. Nenhum animal apresentou lesões cutâneas de fotossensibiliza��ão. O grupo que permaneceu no sol apresentou atividades séricas médias de AST e GGT significativamente maiores que a dos demais grupos (p<0,05) e os animais que permaneceram na sombra apresentaram níveis maiores de GGT (p<0,05) em compara��ão ao grupo controle. A histopatologia das amostras de fígados dos ovinos com sinais clínicos demonstrou tumefa��ão e vacuoliza��ão de hepatócitos, necrose individual de hepatócitos, macrófagos espumosos com cristais birrefringentes intracitoplasmáticos e dentro de ductos biliares e infiltrado mononuclear periportal. Amostras do capim fornecidas aos cordeiros evidenciaram níveis médios de 0,94±0,80% da saponina protodioscina. As observa��ões do presente experimento sugerem que a não exposição ao sol não evita a presença de sinais clínicos da intoxica��ão, mas que a exposição solar exacerba os sinais clínicos.

Importância da intoxica��ão por Amorimia pubiflora (Malpighiaceae) em bovinos em Mato Grosso: reprodução experimental da intoxica��ão em ovinos e bovinos

No município de Colniza, Mato Grosso, a principal limita��ão para expansão pecuária é a ocorrência de "morte súbita" em bovinos, com registros de mortalidade próxima a 50% dos animais. Em visitas realizadas em áreas de ocorrência do problema, nos anos de 2004, 2011 e 2012, constatou-se que havia coincidência entre a ocorrência de "mortes súbitas" no rebanho e a presença de Amorimia pubiflora nas pastagens. As mortes ocorrem durante todo ano, porém acentuam-se no início do período das chuvas, quando há maior quantidade de brota��ão nas áreas de pastoreio. A intoxica��ão foi reproduzida em ovinos e bovinos através da administra��ão de folhas jovens coletadas em dois períodos do ano, e, em ovinos, através de folhas maduras e dos frutos. Nos ovinos que morreram, as primeiras manifesta��ões clínicas foram observadas entre 34min e 17h34min após a administra��ão da planta e a evolução clínica foi de 3min a 15h20min, com uma fase final superaguda de 3 a 21min. As principais altera��ões clínicas encontradas foram taquicardia, evidencia��ão da jugular, tremores musculares, apatia e relutância à movimenta��ão. Todos os sinais acentuavam-se após a movimenta��ão. A fase final superaguda foi caracterizada por relutância para caminhar, cifose, tremores e contra��ões musculares generalizadas, principalmente de membros, cabeça e pescoço. Notou-se também taquipneia com respira��ão abdominal, decúbito esternal e rapidamente lateral ou quedas em decúbito lateral, opistótono, nistagmo e cianose de mucosa oral, seguidos de morte. As folhas jovens, independentemente do período da coleta, foram mais tóxicas; causaram a morte de ovinos a partir de 2g/kg e de um bovino que ingeriu 3g/kg. Já as folhas maduras revelaram-se tóxicas e causaram morte na dose de 20g/kg e os frutos ocasionaram a morte de um ovino que ingeriu 5g/kg. Concluímos que monofluoracetato de sódio (MFA), encontrado na concentra��ão de 0,015% nas folhas em brota��ão de A. pubiflora, é o princípio tóxico responsável pela "morte súbita" causada por Amorimia pubiflora. Esse estudo mostra a importância de A. pubiflora para a região Centro-Oeste do Brasil, principalmente para a pecuária bovina do município de Colniza, MT. Essa planta é tóxica, também, para ovinos e o quadro clínico é similar ao descrito para bovinos.

Fibrose cardíaca associada à intoxica��ão por Amorimia septentrionalis em bovinos

Amorimia septentrionalis contém monofluoracetato de sódio e quando consumida por ruminantes provoca morte súbita. Este estudo teve o objetivo de relatar a epidemiologia, os sinais clínicos e patológicos de surtos de morte súbita em bovinos provocadas por Amorimia septentrionalis nos Estados de Pernambuco e Para��ba. Para isso, realizaram-se visitas técnicas em diversas propriedades nas Microrregiões do Médio Capibaribe/PE e Itabaiana/PB. Oito bovinos foram necropsiados. Coletaram-se tecidos das cavidades abdominal e torácica, além do encéfalo e medula espinhal. As altera��ões clínicas consistiram em lentidão, decúbito esternal prolongado, relutância em se movimentar quando em esta��ão, cansa��o, taquipneia, taquicardia e pulso venoso positivo. Os bovinos que foram forçados a se movimentar apresentaram instabilidade, tremores musculares e queda repentina seguida de vocaliza��ões, movimentos de pedalagem e morte súbita em cerca de 5 a 7 minutos. As principais altera��ões macroscópicas consistiram em edema pulmonar, cora��ão com aspecto globular com áreas esbranquiçadas, petéquias e equimoses no epicárdio, miocárdio e músculos papilares. À microscopia observou-se aumento da eosinofilia do citoplasma dos cardiomiócitos, núcleos picnóticos, cariorrexia, cariólise, perda das estria��ões, edema intersticial, infiltrado inflamatório intersticial mononuclear e áreas multifocais de fibrose cardíaca. Nos rins, constatou-se degenera��ão hidrópico vacuolar e necrose das células epiteliais em túbulos contorcidos. Os sinais clínicos foram semelhantes aos sinais clínicos já descritos em bovinos por plantas que contém MFA. As lesões macro e microscópicas descritas no cora��ão e rins são de grande valor diagnóstico. A. septentrionalis é a principal planta tóxica de interesse pecuário nas microrregiões do Médio Capibaribe e Itabaiana devido às perdas econômicas diretas e indiretas que provoca na pecuária dessas regiões.

Poisoning by Poiretia punctata in cattle and sheep

Poiretia punctata (Willd.) Desv. was associated with cattle and sheep poisoning on nine farms in the State of Sergipe, northeastern Brazil. The animals were found dead or died later after showing clinical signs for up to 18 hours. Two sheep that ingested 40g/kg body weight (g/kg) of fresh P. punctata died three and eight hours after ingestion, respectively. Another sheep that ingested 40g/kg five days after plant collection showed mild clinical signs and recovered after 24 hours. Two sheep that received 20g/kg and another that ingested three daily doses of 20g/kg showed clinical signs, but recovered. Two cattle that ingested 20g/kg of the fresh plant exhibited clinical signs and recovered. The clinical observations of poisoning were depression, ataxia, loss of equilibrium, broad-based stance, head down, falls, mandibular trismus, opisthotonous, nystagmus, and recumbence. Significant gross and histologic lesions were not observed. Samples of P. punctata were analyzed for nitrates, cyanogenic glycosides, and sodium monofluouracetate with negative results. It is concluded that P. punctata is a toxic plant that caused death in cattle and sheep in the State of Sergipe.

A Study of African American Vernacular English in Three Novels and Colloquial Finnish in their Translations – The Dark Tower II: The Drawing of the Three, A Time to Kill and Push

Pro gradu -tutkielma käsittelee afroamerikkalaisen puhekielen (African American Vernacular English, AAVE) käyttöä kolmen englanninkielisen romaanin dialogissa ja suomen yleispuhekielen käyttöä romaanien käännöksissä. Tutkimus on pääasiassa kvantitatiivinen ja deskriptiivinen. Romaanit ovat Stephen Kingin The Dark Tower II: The Drawing of the Three (1987) (Musta torni 2, Kolme korttia pakasta 2005, suom. Kari Salminen), John Grishamin A Time to Kill (1989) (On aika tappaa 1994, suom. Kimmo Linkama) ja Sapphiren Push (1996) (Precious – harlemilaistytön tarina 2010, suom. Kristiina Drews). Alkukielisten romaanien osalta Grisham ja Sapphire suosivat lauseopillisia kielenpiirteitä, kun taas King on suosinut äänteellisiä. Sen sijaan käännöksissä piirteistä yleisimpiä ovat äänteelliset ja harvinaisimpia lauseopilliset. Vaikka käännöksissä sanastolliset piirteet ovat taajaan esiintyviä, äänteellisiä piirteitä esiintyy niitä enemmän. Poikkeuksena on On aika tappaa, jossa sanastollisia piirteitä esiintyy enemmän kuin äänteellisiä. Tulos eroaa Sampo Nevalaisen vuonna 2003 tekemästä tutkimuksesta, jossa hän sai selville, että käännöksissä käytetyt piirteet olivat enimmäkseen sanastollisia, kun taas alun perin suomeksi kirjoitetussa kaunokirjallisuudessa puhekielisyyden vaikutelma saatiin aikaan pääasiassa äänteellisin keinoin. Mahdollinen selitys tässä tutkimuksessa havaitulle erolle on se, että kahdessa romaanissa esiintyvä leimallinen AAVEn käyttö on saanut kääntäjät käyttämään samanlaisia strategioita kuin suomalaiset kirjailijat murretta kirjoittaessaan.

Liminal Monster and the Conflict Between Human and Machine: The Shrike in Dan Simmons’ Hyperion and The Fall of Hyperion

Tarkastelen tutkielmassani Dan Simmonsin kaksiosaista tieteisfiktioteosta, joka koostuu romaaneista Hyperion ja The Fall of Hyperion. Keskityn teoksissa esiintyvään Shrike-hirviöön, joka edustaa ihmiskunnan pelkäämää potentiaalista konfliktia ihmisten ja koneiden välillä. Pelko ja konflikti ovat keskeisiä teemoja paitsi tieteisfiktiossa, myös hirviöteoksissa yleensä, ja näiden kahden käyttö samassa kertomuksessa luo otolliset edellytykset nyky-yhteiskunnan ahdistusten kuvaamiseen. Hirviöitä ja tieteisfiktiota on tätä nykyä tutkittu melko laajalti, mutta Shrike on aiemmin jäänyt vähälle huomiolle. Lähtökohtaisen teoreettisen viitekehyksen tutkimukselleni ovat luoneet Jeffrey Cohenin Monster Theory: Reading Culture, Stephen Asman On Monsters: An Unnatural History of Our Worst Fears sekä Holly Lynn Baumgartnerin ja Roger Davisin At the Interface: Hosting the Monster. Teoksista kokoamani hirviöteorian kautta tarkastelen sitä, miten Shriken puoliksi orgaaninen ja puoliksi keinotekoinen keho heijastaa niitä romaaneissa esiintyviä osa-alueita, joista tulevaisuudenpelko ja ihmisten ja koneiden väliseen konfliktin uhka koostuu. Koska Shrike on puoliksi orgaaninen ja puoliksi keinotekoinen, se on näiden ominaisuuksien kynnyksellä; tässä risteytyneessä kehossa yhdistyvät molemmat ääripäät, jolloin tämä keho myös symboloi osapuolten välistä konfliktia. Konfliktin lisäksi Shrike ilmentää niitä vastakkaisuuksia, joista ihmisten ja koneiden välisen konfliktin pelko rakentuu: itseyttä ja toiseutta, houkuttelevuutta ja luotaantyöntävyyttä, menneisyyttä ja tulevaisuutta sekä utopiaa ja dystopiaa.

Muutoksen avaimet. Tapaustutkimus opinnollisesta mielenterveyskuntoutuksesta

Tämä pro gradu –tutkielma on tapaustutkimus Pollesta potkua –yhdistyksen ja KSL-opintokeskuksen yhteistyössä järjestämästä opinnollisen mielenterveyskuntoutuksen kurssista nimeltä Ole muutos, jonka haluat nähdä. Tutkielmassa pyrin kuvaamaan kurssia ja vastaamaan seuraaviin tutkimuskysymyksiin: Mitä merkityksiä kuntoutumiselle annettiin kyseisellä kurssilla? Miten kurssi toimi kuntoutumisen tukena? Kurssin opetusmenetelmistä nostan erityisesti esiin kuntouttavan musiikkitoiminnan. Tutkielmalla osallistun keskusteluun vapaan sivistystyön mahdollisista voimauttavista vaikutuksista. Tarkastelen kurssia myös kriittisen kasvatussosiologian viitekehyksessä Stephen Brookfieldin ja Theodor W. Adornon teorioiden kautta. Totean, että vapaan sivistystyön kentällä tapahtuvalla opinnollisella kuntoutuksella on mahdollisuuksia voimauttaa yksilöitä ja myös antaa mahdollisuuksia kriittisen teorian peräänkuuluttamaan kriittiseen reflektioon.
