Повний текст джерелаThe Charter of Nizza (2000) has recalled the attention to the theme of human dignity. Although human dignity is conceived as a supreme principle in many different present constitutional systems, we cannot escape from dealing with the problem of human dignity balancing, especially in a context where, for about twenty years, Courts have been treating rights, including human dignity, as balanceable principles. After having analyzed the main problems of juridical systems referring to human dignity (chapter 1) and detailed the most important meanings and contents of the locution ‘human dignity’ in the Charter of Nice and in other normative/juridical documents and contexts (chapter 2), my Ph.D Dissertation analyzes and compares two opposite ethical-normative macro-conceptions of human dignity in their different configurations, pointing out their strengths and their weaknesses: a conception of human dignity as a supreme norm (chapter 3) and a conception of human dignity as a balanceable principle (chapter 4). My hypothesis is that not a third conception beyond a conception of human dignity as a supreme norm and a conception of human dignity as a balanceable principle, but a particular configuration of the first one – a conception of human dignity as a supreme norm of «minimum» content – provides the better ethical-normative human dignity explanation theory, in and for a juridical system. I do not intend to provide a justification of human dignity as a supreme norm of «minimum» content; nevertheless I point out that such a conception allows to overcome weaknesses and to integrate strengths both of a conception of human dignity as a supreme norm on one hand, and of a conception of human dignity as a balanceable principle, on the other hand (chapter 5). The «minimum» content I refer to finds its most explicit formulation in the revision and extension of the Kantian conception of human dignity carried out by the phenomenological tradition. A significant role is played by Jeanne Hersch (1919-2000), with her extension of human dignity from the protection of the person as homo noumenon to the protection of the person as the unity of homo noumenon and homo phaenomenon (1919-2000). The «minimum» content integrates the concept of human dignity with the protection of individual autonomy without reducing human dignity to this last idea. I specifically identified three traits of a possible «minimum» content of human dignity: a personological trait, an eudemonological trait and a deontic trait.

Повний текст джерелаENGLISH ABSTRACT: This study focuses on the requestive behaviour, including perceptions of politeness and directness, of Omani second language (L2) English students at Nizwa University in Oman as revealed by their written responses to real life scenarios. The study is an attempt to improve linguistic understanding of pragmatic differences, with reference to the similarities and differences between Omani L2 English students and L1 English speakers’ communicative proficiency, in order to contribute to improved language teaching curricula. The research design consisted of an initial series of two questionnaires which required that the participants rate given responses based on their perceptions of ‘politeness’ and ‘indirectness’; a third discourse completion test (DCT) that required participants to respond in writing in the form of a request to five real life scenarios; and a fourth questionnaire that required teachers to judge the written responses of the DCT according to five criteria. Additionally, the Omani-speaking teachers of L2 English were interviewed and asked questions relating to their responses from a sociopragmatic/ cultural perspective. The Omani teachers’ responses were then used to assist in the analysis of the written response data. The four instruments above thus used both quantitative and qualitative research methods. The results of the data analysis showed that (1) the query preparatory is considered by both groups to be the most polite request strategy and is used to mitigate imposition; (2) Omani L2 English students consider the words should and must to be most impolite in contrast with the L1 English speakers who consider the mood derivable to be the most impolite request strategy; (3) mild hints are considered far more polite by L1 English speakers than by Omani L2 English students; (4) politeness is influenced by differences in perceptions of social variables such as social distance, social power and degree of imposition; (5) direct strategies are not considered impolite and are used six times more frequently by Omani L2 English students than by L1 English speakers in low-imposition contextual situations; and (6) positive transfer and conventionalisation of the time intensifier has been produced and the strategy is used more than twice as much by the Omani L2 English students than by the L1 English speakers. In contrast, the L1 English speakers use the preparator 11 times more frequently than the Omani L2 English students who predominantly have no pragmalinguistic knowledge of this tactic. The study highlights the need for pragmalinguistic and sociopragmatic training of students in the classroom and for pragmatics to be included in the material and curriculum design of English language learning programmes.
AFRIKAANSE OPSOMMING: Hierdie studie fokus op hoe versoeke, insluitend die persepsies van beleefdheid en direktheid, van tweede taal (T2) Omani studente aan die Universiteit van Nizwa in Oman geformuleer word soos geopenbaar deur hulle skriftelike reaksies op realistiese lewenscenarios tydens vraagstelling. Die studie is ‘n poging om taalkundige begrip van pragmatiese verskille te verbeter, met verwysing na die ooreenkomste en verskille tussen Omani T2 Engelssprekendes en L1 Engelssprekendes se kommunikatiewe vaardighede, ten einde by te dra tot die verbetering van taalonderrig leerplanne. Die navorsing het bestaan uit ‘n aanvanklike reeks van twee vraelyste wat vereis dat deelnemers antwoorde gee op grond van hulle persepsies van beleefdheid en indirektheid; ‘n derde diskoers voltooiings toets (DVT) wat vereis dat deelnemers skriftelik reageer op versoeke in vyf realistiese lewenscenarios; en ‘n vierde vraelys wat vereis dat onderwysers die skriftelike reaksies op die DVT in vyf areas beoordeel. Daarbenewens is die T2 Omani onderwysers ondervra met betrekking tot hulle antwoorde vanuit ‘n sosio-pragmatiese perspektief. Die Omani onderwysers se antwoorde is vervolgens gebruik om die ontleding van die skriftelike response te doen. Die bogenoemde vier instrumente gebruik dus beide kwalitatiewe en kwantitatiewe navorsingsmetodes. Die resultate van die data-analise toon dat (1) die “query preparatory” deur beide groepe as die mees beleefde vraag-strategie beskou word en gebruik word om taakoplegging te versag; (2) T2 sprekers beskou die woorde moet en behoort meestal as onbeskof, in teenstelling met die T1 Engelssprekendes, wat die “mood derivable” as die mees onbeskofte vraag-strategie ervaar; (3) die “mild hint” word as baie meer beleefd deur L1 Engelssprekendes as deur T2-sprekers ervaar; (4) beleefdheid word beinvloed deur verskille in persepsies van sosiale faktore soos sosiale afstand en –druk, en die graad van oplegging; (5) direktheid word nie as onbeskof gesien nie, en kom ses keer meer voor by T2 sprekers in laer taalvaardigheid situasies; en (6) positiewe oordrag en vaslegging van tyd as ‘n drukkrag het voorgekom, en die taktiek word meer as twee keer soveel deur die T2 sprekers as deur die T1 Engelssprekendes gebruik. In teenstelling gebruik die T1 Engelssprekendes die “preparatory” 11 keer meer as die T2 sprekers, wat meestal geen pragma-linguistiese kennis van hierdie tegniek het nie. Die studie beklemtoon die noodsaaklikheid van pragma-linguistiese en sosio-linguistiese opleiding in die klaskamer, en dat pragmatika in materiaal en kurrikulumontwerp vir Engelse taalleer programme ingesluit word.

Este trabalho objetivou analisar a estratégia de aliança nas cooperativas de leite no Brasil, identificando fatores que levaram à sua implementação e seus resultados. O estudo foi realizado nas cooperativas associadas à Central Leite Nilza, criada em 2001 através da joint venture de três cooperativas singulares: Coonai, Casmil e Coopercarmo. Sabe-se que a aliança é uma estratégia eficaz, que é utilizada quando a organização deseja alavancar o crescimento e melhorar sua competitividade, sendo atualmente muito usada nas cooperativas dos principais países produtores de leite. No Brasil, a aliança foi adotada em poucas cooperativas, pois muitos fatores dificultaram sua implantação, como o receio de demissões por parte dos funcionários e a perda do status de dirigentes, entre outros. A abordagem deste trabalho considerou a Teoria de Crescimento da Firma, que procurou identificar os fatores que levaram as cooperativas a adotarem a estratégia, e a análise do setor financeiro, de produção, de recursos humanos e a eficiência social. A razão que levou as cooperativas a formarem a aliança foi a possibilidade de resolverem as dificuldades que cada uma possuía na época. Os principais resultados positivos foram o aumento da escala produtiva e a consolidação da marca. A Coonai foi beneficiada com a estratégia porque repassou sua dívida para as associadas e conseguiu aumentar o indicador de liquidez corrente, porém sua receita operacional líquida diminuiu. Na Coopercarmo houve aumento do endividamento, os índices de liquidez reduziram e sua rentabilidade permaneceu em baixos patamares, mas a receita operacional líquida aumentou, ao contrário do que ocorreu nas principais cooperativas de leite do país. A Central apresentou aumento dos índices de liquidez, redução da rentabilidade e aumento do endividamento no período analisado. A cooperativa Casmil não forneceu dados à pesquisa, o que impossibilitou analisá-la através de indicadores. A divergência de interesses entre os próprios dirigentes dificultou o processo de estruturação da aliança e impulsionou a saída da Casmil em 2004. Portanto, conclui-se que, para as cooperativas de leite terem resultados positivos ao formarem alianças estratégicas, devem primeiramente realizar reformas “internas”, ou seja, que visem melhorar o funcionamento da cooperativa, como a liquidação de dívidas, a profissionalização da gestão e a transparência na administração, por exemplo. A aliança estratégica tem o intuito de alavancar e melhorar a eficiência das cooperativas que estão preparadas, não trazendo resultados positivos para aquelas que tentam utilizar essa estratégia para solucionar os seus problemas.
The objective of this work was to analyze the alliance strategy applied by the dairy cooperatives in Brazil, identifying the factors that led to its application and results. The study was carried out at the three cooperatives associated with Central Leite Nilza, created in 2001 through a joint venture, Coonai, Casmil and Coopercarmo. Alliance is known to be an effective strategy, applied when the organization wants to stimulate growth and improve competitivity, being currently widely used in cooperatives of major milk-producing countries. In Brazil, alliance was adopted by few cooperatives, since many factors can hinder its implementation, such as employees ’fear of losing their jobs and employers’ fear of losing their status, etc. This work approaches the Firm Growth Theory, seeking to identify the factors that led cooperatives to adopt this strategy and to analyze the economic, production, human resources sectors and social efficiency. The reason cooperatives formed an alliance was that it was seen as a possibility to solve the difficulties each was undergoing at the time. The major positive results were productive scale increase and brand name consolidation. Coonai was benefited by the strategy because it passed its debt to its associate and managed to increase the indicators of current and quick liquidity, but the profitability indicators had a reduction starting from 2001, as well as the net operational net income. Coopercarmo had an increase in debt, the liquidity indices reduced and sales remained low, but its operational net income increased, contrary to what occurred in the main dairy cooperatives in the country. Central Leite Nilza showed an increase in the liquidity indices, reduced sales and increased debt during the period analyzed. Casmil cooperative did not provide data for this research, rendering its analysis by indicators unviable. The conflict of interests among the managers themselves hindered the alliance structuring process and led to Casmil’s exit in 2004. Therefore, it is concluded that for the dairy cooperatives to accomplish positive results when forming strategic alliances, they should first undergo internal reforms to improve their functioning, such as debt liquidity, professional management and administration transparency, for instance. The purpose of strategic alliance is to stimulate and improve the efficiency of well- prepared cooperatives, but negative results are obtained for those attempting to apply this approach only to solve their own problems.

Повний текст джерелаAflaj are typical man-made water acquisition and distribution techniques in Oman. They constitute a national and global heritage; their management as a private communal property system has already built the integrity of the resource and the related institutions. We propose to study these systems, specifically in the wilayat of Nizwa, as we hypothesize that they are behind the identified cultural landscape. We propose to define, from crossed perspectives, the two realities, material and social, of this landscape. We used spatial and spatio-temporal analyses of the landscape of the study area by means of identification and characterization of surface components based on multi-spectral spatial remote sensing combined with a good knowledge of the field, and the assessment of the "social gaze", which essentially involves human forces, through a survey among the population living in Oman. As principal results, we carried out a multi-dated descriptive reading of the landscape components of the wilayat of Nizwa, which enabled us to identify a certain tracking of the evolution over time of the anthropic components of the landscape. Concerning the social reality of the landscape, we have established statistical analyses of the survey data which have informed us about socio-economic data specific to aflaj, socio-cultural data concerning practices and perceptions and data on behaviors with an environmental impact and which may, inter alia, threaten the survival of these systems

Повний текст джерелаThe present research examines the European Directive on the right to information in criminal proceedings (Directive 2012/13/EU, hereinafter ‘the Directive’), assessing the impact that it is likely to have on the Italian legal system. Before analyzing the legislation, the thesis provides an historical overview of the status of human rights safeguards in the EU and a description of its multi-layered system of protection. Starting from the early ECJ case law setting out a ‘human rights theory’, the research moves on to consider the Charter of Nice and the development of a European Area of Criminal Justice, until the Stockholm Program and the entry into force of the Lisbon Treaty. In addition, it addresses the question as to whether and to what extent the directives ‘of new generation’ based on art. 82 par. 2 TFEU bring an added value to the aforementioned human rights protection system. Chapters 2 and 3 of the research focus on the analysis of the legislation and on the three meanings that the Directive attaches to the right to information in criminal proceedings, namely, the right to information about rights, the right to information about accusation, and the right to information about case file. The effort is shedding some light on the most innovative prescriptions, while at the same time highlighting how much the EU legislation owes to the ECtHR case law, which is used as a yardstick for the evaluation and interpretation of the Directive. Finally, Chapter 4 addresses the Italian implementing legislation (d. lgs. 101/2014) and the impact of the Directive on our legal system. It finds that the NIM is highly unsatisfactory, as the Italian legislator has failed to comply with the most innovative EU standards. In this regard, the research illustrates the impact of EU prescriptions on the jurisdiction of national judges, in particular, the impact of the ‘new’ right to information about accusation. It concludes that Italian judges can (in)directly apply ECtHR case law standards due the direct effect of the Directive (which can be regarded as an ‘ECtHR case-law codification’).

Повний текст джерелаNa região do Alto Alentejo, foram identificadas várias mineralizações de urânio durante a prospecção sistemática que teve início já antes dos anos 50. Nesta região nenhuma ocorrência foi alvo de exploração, tendo havido todavia, um desmonte experimental no jazigo de Nisa e de terem sido empregues esforços na caracterização da viabilidade económica de cada ocorrência. No presente trabalho foram estudadas em pormenor três ocorrências uraníferas nesta zona: o jazigo disseminado de Nisa, em contexto metassedimentar, encaixado em xistos mosqueados do Grupo das Beiras, junto ao contacto com o granito do Maciço de Nisa; Tarabau, do tipo filoniano, encaixado no granito, também próximo do contacto; e Melriça, outra ocorrência do tipo filoniano, na proximidade de uma fácies pegmatítica do granito, a Norte de Castelo de Vide. As técnicas radiométricas comprovaram-se fiáveis, por comparação com os mapeamentos que estiveram na origem da descoberta destas ocorrências. Os levantamentos radiométricos no campo com recurso a espectrómetro multi-canal mostram o carácter mais imóvel do tório, restringido às zonas de mineralização, enquanto o U e K apresentam halos de dispersão em redor das mesmas. A mineralização uranífera à superfície é constituída somente por fosfatos de U, com preponderância para a torbernite. Em Nisa, foi identificada saleíte, com ocorrência da mineralização nos planos de xistosidade, em filonetes de quartzo e em domínios de alteração, segundo uma direcção geral N60-80ºW. Na ocorrência do Tarabau, foi identificada meta-torbernite com meta-uranocircite associada, especialmente nas zonas de esmagamento adjacentes aos filões. Esta associação resulta de processos de substituição e precipitação tardia com troca do catião na camada hidratada levando à transformação da meta-torbernite em meta-uranocircite. Os óxidos/hidróxidos de ferro surgem associados aos fosfatos de U em alguns domínios, evidenciando relações texturais resultantes da substituição dos fosfatos com a presença de quantidades residuais de P e U na sua composição.
Several uranium mineralizations were identified in the Alto Alentejo region during the exploration works that started before 1950. None of the identified occurrences has been exploited to this day. However, an experimental open pit in the Nisa deposit was developed as well as some efforts to characterize the economic feasibility of the occurrences. In this work, three occurrences were studied: the Nisa disseminated deposit hosted by metasediments, constituted by cordierite schists of the Beiras Group nearby the contact with the Nisa Granitic Massif; Tarabau, hosted by quartz veins, nearby the granite border a crossing its contact; and Melriça, hosted by quartz veins, in the vicinity of a pegmatitic phase of the granite north of Castelo de Vide. The radiometric techniques proved to be reliable, when compared to the maps produced in the exploration of these occurrences. The radiometric surveys on the field used a multichannel spectrometer and showed the immobile character of thorium, which is restricted to the mineralized areas, while both U and K are spread forming halos around the same areas. The U mineralization is exclusively formed by uranyl phosphates. Saleeite was identified in Nisa where the mineralization occurs along the schistosity planes, quartz veinlets and alteration zones, along a general trend N60-80ºW. Meta-torbernite and associated meta-uranocircite were identified in the Tarabau and Melriça occurrences along the brecciated domains of the veins. This association results from cation exchange within the hydrated layer, driving the transformation of meta-torbernite to meta-uranocircite. Iron oxides/hidroxides also occur associated with uranyl phosphates in some domains, with textural relationships resulting from the uranyl phosphate substitution and hosting residual amounts of P and U in its composition.

Повний текст джерелаDominującym trendem w ewolucji roślin okrytonasiennych było przejście od form zdrewniałych (krzewów i drzew) do zielnych. Jego odwrócenie, tj. ewolucja form zdrewniałych z zielnych przodków, nazywana jest „wtórnym zdrewnieniem”. Takie przypadki są najliczniejsze na oceanicznych wyspach i zboczach tropikalnych gór o łagodnym klimacie, ale występują też w rejonach o klimacie śródziemnomorskim z okresową, dotkliwą suszą. Dwie najpowszechniej przywoływane hipotezy zakładają, że wtórne zdrewnienie ewoluuje w odpowiedzi na sprzyjające warunki klimatyczne pozwalające na przedłużony wzrost wegetatywny lub że jest formą przeciwdziałania niekorzystnym efektom kawitacji, gdyż bardziej zdrewniałe gatunki wykazują na nią większą odporność. Apioideae to najliczniejsza i najbardziej zróżnicowana spośród czterech podrodzin wyróżnianych w rodzinie baldaszkowatych (Apiaceae): obejmuje około 3820 gatunków o kosmopolitycznym zasięgu, głównie roślin zielnych, ale także nielicznych krzewów i drzew. Formalna rekonstrukcja stanów ancestralnych wskazuje, że ostatni wspólny przodek Apioideae był rośliną zielną, zatem wszystkie formy zdrewniałe w obrębie tej podrodziny są wtórne. Przedmiotem niniejszej rozprawy jest zbadanie wzorców wtórnego zdrewnienia na przykładzie trzech, odlegle spokrewnionych, kladów Apioideae (Daucinae, Apieae, Tordylieae) oraz przegląd zróżnicowania anatomii drewna w perspektywie całej podrodziny. Badania te mają na celu w szczególności określenie: (a) Czy istnieje zależność między formą życiową a jakościowymi cechami drewna? (b) Czy istnieją wspólne wzorce ewolucji wtórnego zdrewniania pomiędzy daleko spokrewnionymi kladami? (c) Jak długo, w czasie geologicznym, zajmuje ewolucja od formy zielnej do zdrewniałej? (d) Jakie czynniki anatomiczne/ekologiczne mogły przyczynić się do ewolucji wtórnego zdrewnienia w badanych kladach? Rozprawa obejmuje m.in. formalny opis anatomii drewna Apioideae oparty na analizie 154 gatunków ze wszystkich głównych kladów podrodziny. Drewno Apioideae jest nierozróżnialne od blisko spokrewnionych podrodzin (Saniculoideae, Azorelloideae) i charakteryzuje się małą różnorodnością. Odstępstwem od tego jest zróżnicowanie komórek podstawowych drewna, które mogą występować w postaci włókien (drewno włókniste), parenchymy (drewno miękiszowe) lub w formie mieszanej. Parenchymizacja drewna jest silnie związana ze skracaniem międzywęźli oraz polikarpicznością, podczas gdy drewno roślin monokarpicznych i tych o długich międzywęźlach zwykle jest włókniste. Zróżnicowanie form życiowych (według typologii Raunkiaera) nie znajduje odzwierciedlenia w anatomii drewna, w związku z czym formy zielne i zdrewniałe mogą być wzajemnie bardziej podobne anatomicznie, niż gatunki o podobnej formie wzrostu. Ogólnie, u baldaszkowatych z podrodziny Apioideae nie zaobserwowałem zależności między jakościowymi cechami drewna a formą życiową, co świadczy o tym, że ewolucja wtórnego zdrewnienia nie była hamowana/stymulowana przez czynniki anatomiczne, ale raczej warunkowana przez czynniki środowiskowe. Formalna rekonstrukcja stanów ancestralnych wykazała znaczną labilność formy życiowej w każdym z trzech badanych kladów: formy wtórnie zdrewniałe najprawdopodobniej wyewoluowały dwukrotnie w każdym z nich, a w co najmniej jednym przypadku czas potrzebny na zmianę formy życiowej wynosił zaledwie około 130 tysięcy lat. Wszystkie przypadki wtórnego zdrewnienia (za wyjątkiem jednego) miały miejsce w późnym miocenie, czyli okresie wyraźnego osuszenia klimatu. Cztery z nich (Daucus elegans, Daucinae; Deverra spp., Apieae; Nanobubon spp. oraz Notobubon spp., Tordylieae) to taksony występujące obecnie na obszarach doświadczających okresowych susz, co sugeruje, że wtórne zdrewnienie wyewoluowało jako forma przeciwdziałania kawitacji. Pozostałe taksony występują w środowiskach o łagodniejszym klimacie i jest bardziej prawdopodobne, że zdrewnienie powstało u nich w odpowiedzi na sprzyjające warunki pozwalające na wydłużenie czasu wegetacji. Analiza rozmieszczenia wtórnie zdrewniałych i zielnych gatunków Daucinae z Makaronezji pozwoliła potwierdzić wcześniejsze hipotezy o wielokrotnych, niezależnych dyspersjach przedstawicieli tego kladu z kontynentu na wyspy, w tym zidentyfikowała jedną, która mogła mieć miejsce w czasach historycznych i wynikać z zawleczenia przez człowieka. Z kolei formalna analiza biogeograficzna Apieae umożliwiła określenie miejsca różnicowania tego plemienia na zachodni obszar śródziemnomorski (najprawdopodobniej dzisiejsze Maroko) oraz wytypowanie kladu Apium z południowej półkuli jako tego, który w swojej historii doświadczył największej liczby niezależnych dyspersji długodystansowych. Klad ten jest jednocześnie jedynym, który wykazuje tempo dywersyfikacji wyższe niż reszta plemienia, co sugeruje, że w Apieae specjacja netto przyspieszyła w wyniku zasiedlania nowych terytoriów, a nie w rezultacie zmiany formy życiowej.
