Abstract:

This study analyses press treatment of the Korean chaebols from 1989 to 1993. A review of the scholarly literature found that the chaebols were very powerful, but were widely disliked and distrusted by members of the Korean public. As well as controlling many Korean businesses, the chaebols influence the media industries through direct and indirect control. With such influence, and their effort to improve their image after the Seoul Olympics, the researcher expected rather favourable images to be reported in the selected press. A total of seven foreign and domestic newspapers and magazines were selected for the study, which represented various ownership and readership characteristics. Hypotheses were established on the basis of the evidence in Chapters 1 and 2 of the power of the chaebols, and of their recent concern to improve their public images. Quantitative content analysis was then used to investigate significant differences in each selected source in relation to the resource dependencies of the selected newspapers and magazines. Each source was compared and analysed to investigate its distinctiveness and their dependencies due to limited resources. Also, some qualitative content analysis was incorporated to further investigate the ways the Korean chaebols were reported. The research found that rather unfavourable images of the chaebols were often reported in the press, both Korean and overseas. They were favourably described as a contributor in developing in the Korean economy, but were unfavourably described as socially destructive. Our results often contradicted our hypotheses. Also, some significant difference and similarities of reports about chaebols were found especially between the Korean and non-Korean press. The more complex situation revealed by our results was addressed using Turow's(1984) Resource Dependency Theory. Overall, the study supported the more complex picture put forward by the Resource Dependency Theory rather than the somewhat simplistic view that sees ownership as the main influence on media outlets.

Abstract:

The aim of this thesis is to show how Russian antisemitism in Imperial Russia is related to a broader European context, beyond its specific features. The research is focused on the narration by French press of a judicial case involving a Russian Jew, Menahem Mendel Beilis, accused of committing the ritual murder of a child in 1911. The Beilis Affair took place between 1911 and 1913, six years after the resolution of the Dreyfus Affair, which divided the public opinion not only in France but all over Europe.It was quite controversial, and it also had resonance abroad: analyzing the reception of this trial by the French press allows to see how it involved the Dreyfusards and Anti-Dreyfusards sides. It also shows how a case of ritual murder in Russia was transposed and narrated in the French context, thus revealing the broader circumstances in which Russian antisemitism arose. The work will be thus structured in three chapters. The first part will analyze the phenomenon of antisemitism focusing on its origins in the 19th century: this will then allow to discuss the Jewish question in the Russian Empire. This historical context is necessary to focus, in the third chapter, on the Beilis and its reception by the French press.

Abstract:

This thesis investigates whether institutional journalism should receive special treatment at the hands of the law. Special treatment encompasses the affording of benefits to and the imposition of liabilities on journalistic institutions and the individuals who work for them. The arguments against special treatment are pragmatic and theoretical: pragmatic arguments emphasise, inter alia, the difficulty of providing a definition of journalism, and theoretical arguments emphasise the difficulty in explaining why special treatment can be coherent. The former can be addressed by describing how special treatment is already afforded to institutional journalism, both liabilities and benefits, to individuals and institutions, and showing that some of the problems foreseen by the pragmatic arguments have not proved as difficult as they appear. The arguments that special treatment is incoherent can be addressed by arguing that the credibility and assessability of institutional journalism still provide a prima facie rationale for special treatment irrespective of the rise of public speech on the Internet, when combined with the integral nature of journalism to democracy. Two basic arguments are advanced why this is so. The first, the free speech values argument, is a consequentialist account that holds that special treatment is appropriate when (or because) institutional journalism contributes to free speech values. It is attractive, but presents difficulties, both when considered in the abstract and when applied to the free speech value of democracy. The second, a rights-based argument, based on the notion that freedoms of speech and of the Press are distinguishable, can be based on either on Dworkin’s theory of rights as trumps or Raz’s theory of rights as interests. Raz’s account is preferable, as it complements the free speech values thesis in explaining the coherence of special treatment.

Enterocutaneous fistulas are associated with prolonged hospital stay, high morbidity/mortality, and increase in hospital costs. This study aims to describe the use of a vacuum system and normal oral diet in dealing with this problem. Methods: Seventy-four consecutive patients with recent and defined external postoperative fistulas were analyzed. Abdominal imaging was used to exclude abscess and distal obstruction. The fistula tract was sealed with Foley catheter, connected to a negative pressure flask, changed daily for 5, 10 or 15 days, as necessary. Normal oral diet was permitted. Results: No patient died. Serum albumin and transferrin showed significantly higher levels at the end of treatment than at the beginning. The moderate and low-output fistulas had the best results (97% closed). Forty-eight (65%) fistulas closed after five days, 16(22%) after 10 days and 4(5%) after 15 days. Treatment failed in 6(8%) patients, who subsequently underwent surgery. Only one patient with low-output did not close her fistula. The cost of the treatment was US$ 41.75/day and it was considered cost effective. Conclusions: The vacuum system demonstrated good results in the treatment of fistulas. It included simplicity, low cost, short hospital stay, absence of skin breakdown, normal eating, good nutrition and activity patterns

Abstract:

The aim of this study was to establish whether the South African Broadcasting Corporation (SABC) performed according to its mandate in ensuring a fair broadcast coverage of all political parties that participated in the 2014 national general election. The study was undertaken as a result of the complaints by political parties who accused the SABC of bias during the election. The study focused on two SABC radio stations, namely SAFM and UKHOZI FM. In executing the research, particular attention was paid to the coverage of political party manifestos, town hall election debates and radio interviews. The study was written utilising the theoretical paradigm of Social Responsibility Theory, as this is largely deemed the most ethical guide in testing South African journalism. The research was conducted in accordance with the Independent Complaints Authority of South Africa (ICASA) regulations that govern broadcast media during elections. The second part of the analysis deconstructed the SABC’s media coverage of the 2014 election through Media Monitoring Africa – a non-profit organisation that monitors and reports on media coverage of elections, whilst simultaneously taking ICASA stipulated guidelines into account. The MMA and ICASA equipped the study with reports which were compiled after an intense monitoring of SABC’s coverage of the 2014 election. Through the analysis of political parties’ accessibility to the election broadcast programmes on SABC platforms, the study concluded that although there were errors, the SABC treated all parties fairly during the 2014 general elections. The study also found that poor corporate governance at the SABC did not impact directly on the public broadcaster’s ability to deliver fair election broadcasting. By conforming to the social responsibility role that calls for high professional conduct, fairness and objectivity as expected in the public broadcaster, this study found that the SABC was committed to a fair coverage of the 2014 election.

Abstract:

The thesis investigates whether the treatment by the criminal justice system of children who kill in England, starting with the commencement of the police investigation into their crime and ending with the completion of their trial and sentencing processes, has differed over time and if so, the reasons for these differences. It does so by placing a special focus on the adoption of four different concepts of the child, which it develops using the extensive literature available. It carries out its analysis through the exploration of five case studies of children who killed between 1800 and 2000, including the notorious 1993 case of the killing of James Bulger. The thesis draws associations between the approach of different elements of the criminal justice system towards these children and the four concepts of the child and examines their movement over time. It also conducts a comparative analysis with the approaches of the press, public reaction and politicians towards these children, by drawing equivalent associations and observing how they evolve over time. Simultaneously, it observes particular features of the different fields in order to determine their influence over those associations. The thesis concludes that the treatment of these children by the criminal justice system was associated with the various concepts of the child to different degrees over time, though the changes and movements have been to a large extent gradual, unemotional and informed. It also argues that during the late 20th century the approaches of the press, politicians and the public became more erratic and emotional and hence came to deviate substantially from the approach of the criminal justice system. The politicisation of crime, the intense competitiveness of the press and the growing involvement and reactions of the public in matters of juvenile crime, which constituted changes in the three fields during the 1990s, are believed to be instrumental in this divergence. Its findings constitute a platform on which a framework for reform of the treatment within the criminal justice system of children who kill can be founded in the future.

Abstract:

Este estudo procurou investigar a utilização de polímeros para condicionamento de lodo de ETE para desidratação em filtro prensa de placa e verificar as eventuais vantagens em relação ao condicionamento com cal e cloreto férrico. Para isso foram realizadas pesquisa bibliográfica, consulta a fornecedores de polímeros e de equipamentos e trabalhos experimentais em laboratório e em escala piloto com lodo gerado nos digestores anaeróbios da ETE Barueri da SABESP que mostrava interesse em fazer o condicionamento do lodo com polímeros. Atualmente, na ETE Barueri o condicionamento de lodo é feito com cal e cloreto férrico, com dosagens em torno de 25% e 10% respectivamente e a desidratação em filtro prensa de placas, com tempo de ciclo de 4 horas, produz tortas com 40% de teor de sólidos e densidade de 1,20 kg/L. Nos experimentos foram utilizados polímeros catiônicos de alto peso molecular. O equipamento piloto utilizado foi um filtro prensa de placa do tipo membrana diafragma com dez placas de 800 x 800 mm. Nos ensaios do filtro prensa piloto, com a utilização de polímero em pó para o condicionamento de lodo, indicou-se uma redução nos custos de produtos químicos consumidos em relação ao condicionamento com cal e cloreto férrico. O condicionamento com polímero em pó e cloreto férrico, com dosagens respectivamente de 4,83 kg/ton e 6,3%, resultou numa torta com teor de sólidos de 31% e densidade de 1,13 kg/L. Já o condicionamento feito somente com polímero em pó, com dosagem de 5,38 kg/ton, resultou numa torta com teor de sólidos de 30% e densidade de 1,08 kg/L, porém apresentou problemas na soltura das tortas. A utilização de polímeros permitiu trabalhar em taxas iniciais de filtração mais altas, resultando num tempo de filtração em torno de 120 minutos, implicando em tempos de ciclo mais curtos.
This study investigated the utilization of polymers for the conditioning of the sludge generated at Wastewater Treatment Plants (WTP) for dewatering at filter presses, verifying the eventual advantages in comparison with the conditioning with lime and ferric chloride. Specific bibliography was researched, polymer and equipment suppliers were consulted and experimental studies were carried out at the laboratory and in a pilot scale. The sludge was generated at the anaerobic digesters of Barueri WTP operated by SABESP which has shown interest in this method. Currently, at Barueri WTP the sludge conditioning is performed with lime and ferric chloride at dosages around 25% and 10%, respectively. The dewatering is processed by filter presses during a cycle period of 4 hours, producing cakes with 40% of solids and a density of 1,20 kg/L. The experimental studies were carried out with high molecular weight cationic polymers. The pilot equipment consisted of a filter press with a diaphragm membrane with 10 plates measuring 800 x 800 mm each. During the tests at the pilot filter press, when dry polymers for sludge conditioning were utilized, it was verified that the cost of chemical products consumed was reduced in comparison with the conditioning with lime and ferric chloride. The sludge conditioning with dry polymers and ferric chloride at respective dosages of 4,83 kg/ton and 6,3% resulted in cakes with 31% of solids and density of 1,38 kg/L. On the other hand, the sludge conditioned only with dry polymers at a dosage of 5,38 kg/ton resulted in cakes with 30% of solids and density of 1,08 kg/L, but the cake release from the plates was difficult. The utilization of polymers allowed higher initial filtration rates resulting in a 120 minute filtration period with a consequent reduction of the cycle time.

Abstract:

Este trabalho buscou analisar dois materiais para fabricação de navalhas para corte de sucata, de forma a identificar aquele que melhor atenda às solicitações de desgaste dentro de um custo competitivo. Foram realizados testes comparativos de desempenho entre navalhas de aço AISI S1 e SAE 4340, sendo este último o material base utilizado atualmente para a fabricação de navalhas para corte de sucata na Gerdau Aços Especiais Charqueadas. O estudo foi realizado durante o processamento de sucata em uma Prensa Tesoura Harris BSH 1123, sendo que as medições de desgaste foram realizadas nas arestas de corte com a utilização de um relógio comparador. Os resultados mostram que o aço ferramenta, apesar de seu elevado custo e necessidade de maior controle durante o tratamento térmico, é superior em todos os aspectos, apresentando a metade do desgaste do aço ligado quando utilizado nas mesmas condições e trazendo benefícios operacionais como a redução do tempo de troca das navalhas, sendo o material mais indicado para este fim.
Performance trials were carried out to identify the most suitable material for the manufacturing of blades for scrap cutting considering resistance for wear specifications as well as competitive cost. The materials tested were AISI S1 and SAE 4340, being the latter the material currently used for this application at Gerdau Aços Especiais Charqueadas. The study was conducted during scrap processing in a Harris BSH 1123 shearing press. In order to measure the cutting edge wear, a dial gauge was employed. The results show that the tool steel, despite its higher cost and more complex heat treatment process, is superior for all analyzed aspects, presenting less than half of the wear shown by the low alloyed steel when processing scrap under the same conditions. Other additional operational benefits also were obtained as a decrease in the set up time, being the material of choice for this task.

Research for better performance materials in biomedical applications are constants. Thus recent studies aimed at the development of new techniques for modification of surfaces. The low pressure plasma has been highlighted for its versatility and for being environmentally friendly, achieving good results in the modification of physic chemical properties of materials. However, it is requires an expensive vacuum system and cannot able to generate superficial changes in specific regions. Furthermore, it is limits their use in polymeric materials and sensitive terms due to high process temperatures. Therefore, new techniques capable of generating cold plasma at atmospheric pressure (APPJ) were created. In order to perform surface treatments on biomaterials in specific regions was built a prototype capable of generating a cold plasma jet. The prototype plasma generator consists of a high voltage source, a support arm, sample port and a nozzle through which the ionized argon. The device was formed to a dielectric tube and two electrodes. This work was varied some parameters such as position between electrodes, voltage and electrical frequency to verify the behavior of glow discharges. The disc of titanium was polished and there was a surface modification. The power consumed, length, intensity and surface modifications of titanium were analyzed. The energy consumed during the discharges was observed by the Lissajous figure method. To check the length of the jets was realized with Image Pro Plus software. The modifications of the titanium surfaces were observed by optical microscopy (OM ) and atomic force microscopy (AFM ). The study showed that variations of the parameters such as voltage, frequency and geometric position between the electrodes influence the formation of the plasma jet. It was concluded that the plasma jet near room temperature and atmospheric pressure was able to cause modifications in titanium surface

Abstract:

Дисертація на здобуття наукового ступеня кандидата технічних наук (Ph.D) за спеціальністю 05.17.11 – технологія тугоплавких неметалічних матеріалів. – Національний технічний університет "Харківський політехнічний інститут", Харків, 2019. Дисертація присвячена створенню оптичних кольорових стекол зі спектральними параметрами – коефіцієнтом пропускання на довжині хвилі 1060 τ(λ₁₀₆₀) >65 %, поглинанням у спектральному діапазоні до 950 нм та технологіям їх отримання. На цей час існуючі стекла лише частково виконують ці умови, або технології їх отримання є нерентабельними для масового виробництва, тому було поставлена задача про створення стекол, які б могли задовольняти ці умови з фактором технологічності у виробництві. Вирішення досягнуто завдяки дослідженням поглинальної дії системи барвників Cr₂O₃-Mn₂O₃ у системі R₂O-PbO-SiO₂ та додатковому нанесенню оптичного покриття. Завдяки дослідженням було встановлено механізми забарвлення з урахуванням впливу домішок-барвників (Fe₂O₃/FeO), а також знайдені оптимальні концентрації барвників у склі. При розробці технології отримання оптичного кольорового скла були дослідженні основні технічні операції та методи контролю якості скла, що дозволяє отримувати дане скло у виробничому масштабі. Розроблені параметри контролю протікання процесів гомогенізації та освітлення розплаву скла з метою підвищення якості продукції. Також були розроблені методики обробки деталей зі скла та нанесення оптичних покриттів. Для автоматизації виробництва даної продукції та зменшення впливу людського фактору було розроблено програмне забезпечення автоматичної системи керування технологічними процесами (АСК ТП).
Dissertation for the Ph.D. degree in specialty 05.17.11 – "Technology of refractory nonmetallic materials". – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. The dissertation is devoted to the development of infrared optical glasses with next spectral characteristics, as well as the creation of technologies for their production. The spectral characteristics are transmittance at a wavelength of 1060 nm 1060 τ (λ₁₀₆₀)>65% and absorption in the spectral range up to 950 nm. The solution to this problem was achieved due to the addition of the Cr₂O₃-Mn₂O₃ colorant system to the glass matrix of the R₂O-PbO-SiO₂ system, as well as the additional optical thin-film coatings. For production implementation optical color glass a pot regenerator furnace was used. The ceramic vessel with a volume of 500 liters was chosen. The temperature of the production was 1420 ± 20 °С. To improve the quality of optical glass practical studies were carried out. These studies devote to the modes of batch filling, mixing and temperature parameters. Fundamental researches were conducted on the mode of cooling of colored optical glass. For the first time for such glasses the stage of cooling made by inertia cooling of the furnace construction without gas. Due to introduction of the results and improving of the spectral parameters the volume of quality glass yield has increased. The software was developed to control the technological processes of the furnace in automatic mode.

Дисертація на здобуття наукового ступеня кандидата технічних наук (Ph.D) за спеціальністю 05.17.11 – технологія тугоплавких неметалічних матеріалів. – Національний технічний університет "Харківський політехнічний інститут", Харків, 2019. Дисертація присвячена створенню оптичних кольорових стекол зі спектральними параметрами – коефіцієнтом пропускання на довжині хвилі 1060 τ(λ₁₀₆₀) >65 %, поглинанням у спектральному діапазоні до 950 нм та технологіям їх отримання. На цей час існуючі стекла лише частково виконують ці умови, або технології їх отримання є нерентабельними для масового виробництва, тому було поставлена задача про створення стекол, які б могли задовольняти ці умови з фактором технологічності у виробництві. Вирішення досягнуто завдяки дослідженням поглинальної дії системи барвників Cr₂O₃-Mn₂O₃ у системі R₂O-PbO-SiO₂ та додатковому нанесенню оптичного покриття. Завдяки дослідженням було встановлено механізми забарвлення з урахуванням впливу домішок-барвників (Fe₂O₃/FeO), а також знайдені оптимальні концентрації барвників у склі. При розробці технології отримання оптичного кольорового скла були дослідженні основні технічні операції та методи контролю якості скла, що дозволяє отримувати дане скло у виробничому масштабі. Розроблені параметри контролю протікання процесів гомогенізації та освітлення розплаву скла з метою підвищення якості продукції. Також були розроблені методики обробки деталей зі скла та нанесення оптичних покриттів. Для автоматизації виробництва даної продукції та зменшення впливу людського фактору було розроблено програмне забезпечення автоматичної системи керування технологічними процесами (АСК ТП).
Dissertation for the Ph.D. degree in specialty 05.17.11 – "Technology of refractory nonmetallic materials". – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. The dissertation is devoted to the development of infrared optical glasses with next spectral characteristics, as well as the creation of technologies for their production. The spectral characteristics are transmittance at a wavelength of 1060 nm 1060 τ (λ₁₀₆₀)>65% and absorption in the spectral range up to 950 nm. The solution to this problem was achieved due to the addition of the Cr₂O₃-Mn₂O₃ colorant system to the glass matrix of the R₂O-PbO-SiO₂ system, as well as the additional optical thin-film coatings. For production implementation optical color glass a pot regenerator furnace was used. The ceramic vessel with a volume of 500 liters was chosen. The temperature of the production was 1420 ± 20 °С. To improve the quality of optical glass practical studies were carried out. These studies devote to the modes of batch filling, mixing and temperature parameters. Fundamental researches were conducted on the mode of cooling of colored optical glass. For the first time for such glasses the stage of cooling made by inertia cooling of the furnace construction without gas. Due to introduction of the results and improving of the spectral parameters the volume of quality glass yield has increased. The software was developed to control the technological processes of the furnace in automatic mode.

Abstract:

The press hardening belongs to state-of-the-art technology at sheet metal forming to gain high strength and crash resistant parts in automotive industry. This process could establish due to its cost- and esourceefficiency. According to ongoing developments on direct press hardening processes it is necessary to describe and understand the thermo-mechanical treatment of 22MnB5. Therefore the flow behavior and phase transformation during cooling with simultaneous forming is investigated. The experimental process considers industrial parameters in order to get industry-oriented results. In deep drawing processes the sheet metal is roped into the draw die and bended around the die edge. Thereby sheets perform different stages of compressive and tensile strain at the die oriented side and the punch oriented side of the sheet. There are different stages and values of stress and strain according to several layers of the sheet over its cross-section. The values of stress, strain and forming rate were FEcalculated for industry-relevant bending radii and sheet thicknesses of manganese-boron steel 22MnB5. According to the calculations different cooling and forming strategies were performed by dilatometric tests. The forming behavior is described by the microstructural development with regard to the cooling rate and temperature. Beside the influence of austenite forming on the phase transformation and mechanical properties is considered. A prospective view is given to illustrate ongoing examinations under compressive and combined tensional and compressive forces.

ENGLISH ABSTRACT: When South African President Thabo Mbeki began doubting that HIV was the cause of AIDS in the late 1990s, failed to provide AIDS medication and stalled its introduction, openly supported HIV pseudoscientists and doubted HIV statistics, one of the most widely reported debates in the country’s history emerged. When two independent 2008 studies found that the death of approximately 330 000 South Africans could have been prevented between 1999 and 2007 if President Mbeki’s HIV policy made provision for AIDS medication, the AIDS debate was re-introduced, and it was these findings that provided the motivation for this study. The purpose of this study was to provide a historical perspective on HIV reporting in the media during Mbeki’s presidency in order to answer how the media reflected and reported on his HIV policy, and also to provide possible reasons for the way the media reported on the matter. Research has shown that the government (particularly President Mbeki and his health ministers) and AIDS social movement organisations (particularly the Treatment Action Campaign [TAC]) were the main actors framing the AIDS epidemic in South Africa. Thus, this study examined the media’s HIV trail in reporting on these actors’ responses and counter-responses by means of content analysis. Qualitative analysis, in the form of questionnaires sent to health journalists who reported on HIV during this period, was completed in order to provide the possible reasons for the media’s reporting style. During the content analysis it was found that the media reporting was mostly positive towards the TAC and mostly critical towards Mbeki and his government, and the results of the questionnaires verified this, but also provided reasons why the media were mostly critical of Mbeki and his government. One principal reason was that the government’s policies on HIV were so blatantly contrary to scientific evidence and medically unethical that it was the media’s duty to fulfil their watchdog and surveillance role.
AFRIKAANSE OPSOMMING: Toe die Suid-Afrikaanse president, Thabo Mbeki, in die laat jare negentig begin het om die oorsaak van VIGS in twyfel te trek, daarin misluk het om VIGS-medikasie te verskaf en produksie daarvan vertraag het, en openlik MIV-pseudowetenskaplikes ondersteun het en MIV-statistiek bevraagteken het, het ’n debat met moontlik van dié wydste nuusdekking in die geskiedenis van die land posgevat. Die VIGS-debat het weer op die voorgrond beland nadat twee onafhanklike studies in 2008 bevind het sowat 330 000 Suid-Afrikaners se dood kon tussen 1999 en 2007 vermy gewees het indien president Mbeki se MIV-beleid voorsiening gemaak het vir die verskaffing van VIGS-medikasie. Hierdie bevindinge het die motivering vir die studie verskaf. Die doel van hierdie studie was om ’n historiese perspektief van die mediadekking van MIV tydens Mbeki se presidentskap te verskaf om sodoende vas te stel hoe die media die debat oor Mbeki se MIV-beleid weerspieël het, maar ook om die redes te bepaal vir die manier waarop die media oor die kwessie berig het. Navorsing het getoon die regering (spesifiek president Mbeki en sy gesondheidsministers) en aktivistegroepe (spesifiek die Treatment Action Campaign [TAC]) was die hoofkarakters betrokke by die fokussering van die VIGS-epidemie in Suid-Afrika. Dus het hierdie studie probeer om die media se MIV-spore met betrekking tot beriggewing oor hierdie akteurs se stellings en reaksies deur middel van inhoudanalise te bestudeer. Kwalitatiewe analise in die vorm van vraelyste wat aan gesondheidsjoernaliste gestuur is wat in hierdie tydperk beriggewing oor MIV gedoen het, is gebruik om moontlike redes te verskaf vir die manier van beriggewing. Tydens die inhoudanalise is bevind dat mediadekking meestal positief teenoor die TAC was en meestal negatief teenoor Mbeki en sy regering. Die resultate van die vraelyste het dít bevestig, en redes verskaf waarom die media meestal krities was teenoor Mbeki en sy regering. Een van die vernaamste redes was dat die regering se beleidsrigtings met betrekking tot MIV so blatant teen wetenskaplike bewyse gekant was en boonop medies oneties was, dat dit juis die media se plig was om die rol van waghond te speel.

La tratta di esseri umani è un crimine che ha attratto progressivamente l’attenzione dei media negli ultimi anni, durante il consolidamento delle politiche anti-tratta internazionali e nazionali.

È questo il contesto nel quale s’inserisce la ricerca, il cui scopo è investigare se le misure legislative nazionali anti-tratta possano influenzare la copertura a mezzo stampa della tratta di persone in un Paese. A questo scopo, sono state formulate sei ipotesi, verificate attraverso l’analisi di quattro quotidiani di stampo conservatore e liberale in Italia e Regno Unito dal 2000 al 2010: Corriere della Sera, La Repubblica, Daily Telegraph, The Guardian. Il test delle ipotesi è avvenuto tramite la content analysis, i cui risultati sono stati validati da interviste in profondità. L’analisi dei dati ha rivelato che la relazione tra l’agenda legale e quella della stampa è risultata essere positiva nei dieci anni di riferimento. Pur presentando dei limiti, questo studio può essere considerato come un passo verso la comprensione di come i giornali affrontino il tema della tratta e di quali fattori influenzino le loro scelte.

As regards the data analysis, the relationship between the legal agenda and the press agenda appears to have been close during the ten reference years. Notwithstanding its limitations, this study can be read as the first stage in understanding how newspapers approach the issue of trafficking and what factors may influence their choices.

Abstract:

Afin de participer aux décisions politiques, suivant des procédures institutionnalisées ou par le simple fait de se forger une opinion, les médias d’information jouent un rôle central. Avec les problématiques écologiques contemporaines, cette exigence de participation s'accroît. Comment, dans les discours médiatiques, les enjeux environnementaux sont-ils traduits et mis en forme ? Par l’étude de deux trajectoires de controverses sociotechniques (autour du gaz de schiste et de la centrale nucléaire de Fessenheim) dans la presse généraliste (Le Monde et 20minutes) et un éventail de journaux plus large, nous explorons comment celles-ci se fixent dans différents répertoires de « montée en généralité ». À l’aide d’une articulation entre méthodes quantitative (lexicométrie) et qualitative (analyse du discours), nous dévoilons un dialogue entre différents « mondes de justification » (Boltanski et Thévenot, 1991) et cherchons l’existence d’une « cité écologique » (Lafaye et Thévenot, 1993) dans l’espace public médiatique
In order to participate in political decisions, following institutional processes or through the simple fact of opinion-forming, the informative media play a central role. With the contemporary ecological problems this kind of involvement is ever more needed. How are environmental issues interpreted and shaped by media discourses ? By studying the trajectories of two socio-technical controversies (shale gas and the nuclear power plant of Fessenheim) in the mainstream press (Le Monde and 20minutes) and in a larger range of newspapers, we explore how these are linked to different “forms of generalization”. By combining quantitative (lexicometric analysis) and qualitative (discourse analysis) methods, we reveal a dialogue between different “worlds of justification” (Boltanski and Thévenot, 1991) and search for the existence of an “ecological city” (Lafaye and Thévenot, 1993) in the media public sphere

Abstract:

Les médias et les réseaux sociaux constituent une source importante de diffusion et de communication des résultats de la recherche clinique. Le terme « spin » est utilisé lorsque la présentation et l’interprétation des résultats d’une étude sont déformées par les auteurs que ce soit intentionnellement ou involontairement. Les spins exagèrent les effets bénéfiques des interventions et sous-estiment les effets indésirables. Les principaux objectifs de ce travail étaient :1) d’évaluer la prévalence des « spins » dans les articles de presse, d’identifier les différentes stratégies de spin et de développer une classification de spin ; 2) d’identifier les facteurs associés à une diffusion des résultats via les réseaux sociaux et 3) d’étudier comment les articles scientifiques rapportés avec des spins diffusent via les réseaux sociaux, à partir de l’exemple de l’essai DAPT 2014. Dans un premier temps, nous avons réalisé une revue systématique des articles de presse décrivant les résultats d’études évaluant une intervention et indexés dans la rubrique santé de Google. Nous avons développé une classification des stratégies de spin pour les articles de presse et montré que la prévalence des spins est élevée. Dans un deuxième temps, nous avons réalisé une étude de cohorte d’articles évaluant les traitements contre le cancer pour identifier les facteurs associés à une attention médiatique élevée. Le critère de jugement principal était l’attention portée par les médias et les réseaux sociaux mesuré par le « score Altmetric ». Nos résultats ont montré l’importance de l’accès libre et des communiqués de presse. Enfin, nous avons effectué une analyse systématique de l’attention portée par les médias et les réseaux sociaux autour de l'étude DAPT qui était rapporté avec des spins sous estimant les effets indésirable de l’intervention. Nous avons montré que l’interprétation des résultats par les auteurs sont rarement contredits. Ces travaux ont permis de mettre en évidence l’importance des spins dans les médias et de développer des outils (classification de spin) pour améliorer la diffusion des résultats de la recherche
Mass media and social networks are important sources of disseminating and communicating clinical research. The term “spin” is used when the presentation and interpretation of the results of a study is distorted by the authors intentionally or unintentionally. Spins exaggerate the beneficial effects of interventions and underestimate adverse effects. The main objectives of this PhD were (I) to assess the prevalence of spin in health news, as well as identify and classify different strategies of spin; (II) to identify factors associated with dissemination of research results through online media, and (III) to explore how results of a trial reported with spin were disseminated to the scientific community and online media, using the 2014 DAPT trial as a case study. For the first aim, we performed a cross-sectional study of health news and described the distortion of research results of studies evaluating an intervention in Google health news. We developed a classification of spin for health news and showed a high prevalence of spin. For the second aim, we performed a cohort study of articles evaluating cancer treatments and identify factors associated with high online media attention. The primary outcome was the attention received by media and social networks measured by Altmetric score. Our results highlighted the importance of open access and press releases. Finally, we performed a systematic review of attention received by media and social networks surrounding the DAPT study which were reported with spin and undermine the adverse effects of the treatment. We showed that the interpretation of results by authors was rarely criticized. These results highlighted the importance of spin in mass media and provided a tool (classification of spin) to improve the dissemination of research results

Abstract:

Pharmaceuticals are ubiquitous water contaminants that have shown detrimental effects on aquatic organisms at low concentrations. National authorities are starting to plan and implement measures (Wastewater treatment plants (WWTP) upgrades and source control) to reduce pharmaceutical concentrations in rivers. Decision-makers use models to predict the fate and transport of pharmaceuticals and to evaluate measures for the reduction of pharmaceuticals. However, there is still large uncertainty in the predictions which compromises decision-making. The cost of implementing WWTP upgrades at catchment level can be daunting, hence the development of tools that optimize the costs are indeed required. Moreover, there is little scientific information on the effectiveness of source control measures for the reduction of pharmaceutical concentrations at catchment scale. The aim of this thesis is to provide decision-makers with modelling tools for the evaluation of measures to reduce pharmaceutical concentrations in rivers. The modelling tools include uncertainty in the whole decision-making process

Alguns països estan començant a planificar i implementar mesures (millores en les EDARs i control de les fonts de la contaminació) per reduir les concentracions de fàrmacs en rius. Els responsables en la presa de decisions utilitzen models per a estimar concentracions de fàrmacs i per a avaluar mesures orientades a reduir aquestes concentracions. Malgrat això, encara existeix molta incertesa en les predictions, la qual cosa compromet la presa de decisions. A més, es requereix desenvolupar eines per optimitzar els costos que se'n deriven.

Abstract:

Les maladies cardiovasculaires sont la principale cause de décès dans le monde. Actuellement, leur prévalence croît en Afrique subsaharienne où l'hypertension représente un facteur de risque cardiovasculaire majeur. Différents médicaments sont utilisés pour le traitement de l'hypertension mais dans les pays à revenu faible en général, et en R.D.Congo en particulier, le niveau socio-économique bas de la population pousse cette dernière à faire appel à la médecine traditionnelle. En R.D.Congo, les tradithérapeutes utilisent une multitude de plantes pour traiter l’hypertension. Cependant, les propriétés pharmacologiques de certaines de ces plantes sur la fonctionnalité vasculaire n’ont pas encore été étudiées de manière approfondie.

Afin de donner une base scientifique à l’utilisation de ces plantes dans le traitement de l'hypertension artérielle en médecine traditionnelle congolaise, nous avons réalisé dans un premier temps une enquête ethnobotanique. Celle-ci a été menée auprès de tradipraticiens de Kinshasa et du Bas-Congo, dans l'ouest de la R.D.Congo, afin d'obtenir des informations spécifiques sur les plantes qui sont utilisées pour traiter l'hypertension. Suite à cette enquête, trois plantes ont été sélectionnées :les feuilles et les écorces de racines de Combretum racemosum P. Beauv (Combretaceae), les feuilles de Combretum celastroides subsp. laxiflorum Welw (Combretaceae) et les écorces de tronc et de racines d'Hymenocardia acida Tul. (Euphorbiaceae). L'évaluation de l'effet vasorelaxant des extraits polaires issus de ces plantes sur les anneaux d’aorte isolée de rat a montré que les extraits testés ont un effet vasorelaxant endothélium-dépendant. Tous les extraits induisent cet effet via la voie du NO-GMPc alors que ceux de feuilles et d'écorces de racines de Combretum racemosum agissent également via la voie des prostanoïdes. Ces extraits ont aussi une action antioxydante. Enfin, l'administration chronique des extraits polaires de feuilles de Combretum celastroides subsp. laxiflorum et d'écorces de racines d'Hymenocardia acida aux rats spontanément hypertendus a montré que ces deux extraits possèdent une activité antihypertensive. Dans le but de déterminer les composés phytochimiques responsables de l’activité vasorelaxante observée, les extraits polaires de feuilles de Combretum celastroides subsp. laxiflorum et d'écorces de racines d'Hymenocardia acida ont été soumis à un fractionnement sur une colonne de polyamide. Toutes les fractions obtenues ont présenté une activité antioxydante, mais l'activité vasorelaxante était concentrée dans une fraction dont l'analyse par chromatographie liquide couplée à la spectrométrie de masse après thiolyse a indiqué qu'elle était enrichie en procyanidines. En conclusion, notre étude montre l'intérêt de ces plantes dans le traitement de l'hypertension en médecine traditionnelle congolaise, intérêt qui mérite d’être confirmé par des études cliniques rigoureuses./

Cardiovascular diseases represent a major cause of death in the world. Currently, their prevalence grows in sub-Saharan Africa where hypertension represents a major cardiovascular risk factor. Different drugs are used for the treatment of hypertension, but in low-income countries in general and in the D.R.Congo in particular, low socio-economic level forces the population to frequently recourse to the traditional health systems. In D.R.Congo, the traditional healers use a variety of plants to treat hypertension, but the pharmacological properties of some of these plants on vascular function have not been investigated.

To provide a scientific basis for the use of these plants in the treatment of hypertension in Congolese traditional medicine, we first carried out an ethnobotanical survey among traditional healers in some districts of Kinshasa and Bas-Congo, in the west of D.R. Congo, to obtain specific information about the plants that are used as antihypertensive remedies. As a result of this investigation, three plants were selected :leaves and root bark of Combretum racemosum P. Beauv (Combretaceae), leaves of Combretum celastroides subsp. laxiflorum Welw (Combretaceae), and trunk bark and root bark of Hymenocardia acida Tul. (Euphorbiaceae). The evaluation of the vasorelaxant effect of the polar extracts from these plants on isolated rat aorta showed that all extracts have an endothelium-dependent vasorelaxant effect. All extracts induce the vasorelaxant effect through the NO-cGMP pathway while those of Combretum racemosum leaves and root bark also act via the prostanoids pathway. These extracts also showed an antioxidant activity. Chronic administration of polar extracts of Combretum celastroides subsp. laxiflorum leaves and Hymenocardia acida root bark to spontaneously hypertensive rats showed that both extracts have an antihypertensive activity. Both extracts were fractionated on a column of polyamide in order to determine the nature of the compounds responsible for the vasorelaxant activity. All fractions obtained had an antioxidant activity but the vasorelaxant activity was concentrated in one fraction. Analysis of this fraction by liquid chromatography-mass spectrometry after thiolysis indicated that it was enriched in procyanidins. In conclusion, our study shows the interest of these plants in the treatment of hypertension in Congolese traditional medicine, interest which should be confirmed by rigorous clinical studies.

The study examines the effectiveness of sludge dewatering using filter presses in Feng Yuan Purification Plant of Taiwan Water Corporation. By installing an experimental filter press and using polypropylene filters, the study tries to remove the liquid from liquid-solid sludge containing 5%, 10%, 15% and 37.3% solids for 30, 60 and 90 minutes by batch conditioning. The pressure is set at 5.5 kg/cm2 with the voids between plates(filter chambers) measuring 2.5cm, 3.0 cm, 3.5cm, 4.0 cm and 4.5 cm respectively. The study observes the filtrate, the weight and moisture content of each filter cake to investigate the influence of parameters of a filter press on the production and the moisture content of filter cakes. Based on the results of the first phase of the experiment, another void between plates(filter chambers) measuring 3.5 cm is designed for pressure tests with fabric filters of low permeability and high permeability. The pressure is set at 4 kg/cm2, 5.5 kg/cm2, and 7 kg/cm2 respectively to dewater liquid-solid sludge containing 29.94% solids by continuous feeding for the observation of the influence of pressure on the weight and moisture content of filter cakes. The first phase of the experiment indicates that a narrow void between plates(filter chamber) measuring 2.5cm and the pressure setting at 60 minutes give the best dewatering efficiency for sludge containing a lower percentage of solids of 5%, 10%, 15%. On the other hand, when sludge contains solids up to 37.3%, good filter cakes with low moisture content can be produced by a wide void measuring 4.5 cm and the pressure setting of 30 min. We conduct pressure tests with polypropylene filters with different permeability and summarize views of the filters under the microscope at 400 times of magnification. Take 1000 L of filtrate from the first batch of condition for particle size distribution by LASER diffraction. The results show that polypropylene filters with large mesh size and low permeability facilitate better dewatering than those with small mesh size and high permeability. The second phase pressure tests indicates that the increased pressure from 4 kg/cm2 to 7 kg/cm2 help add the weight and reduce the moisture content of filter cakes.

The written press in the maneuver of mass communication represents an extremely important role for Latin America. For the feminine presidencies, the treatment of their images is influenced deeply of the social, human and culture matters on the local public. The example of the written press on the reflection and judgment of the argentineans to the governors are affected deeply by Latin American culture hybrid as reacted on the cultivation effect. Specially, the argentine newspapers, magazines, and impression of related publication are expression remarkable, to inform different degrees from the reports. Then involved the two argentine feminine presidencies during its predominant time were different published commentaries, public opinion and different point of view in the homogeneity and heterogeneity from them. In seventy to eighty decades is the period when María Estela Martínez lived at the turbulent times, when the internal country by the leftist influence was affected in politics, economy and society. In another view of the titular presidency, Cristina Fernández situates in the time where the flood of political manipulation and excessive exaggeration of medias, thus compares both presidencies that belong to hybrid cultural phenomenon, in when leaves from history is different from before and after. Under the structure of the cultivation theory, if neutrality of editorials had been suffered implication of the political force, until it affected newspapers and the magazines with threat for closing and suspension of his publications; for a place with prosperous of culture hybrid like Latin America, if the freedom of expression was limited and prohibited, it could be a relative index from which the public opinion was received or not. As much the veteran journalists of medias, did critic on the governors in the part of image and the level of the confidence which has been harmed and diminished. This thesis has to focus to the two argentine feminine presidencies as the cases of the objective and outline of the investigation; and analyze the bibliographies related of the written press, as induce the conclusion of this thesis and discovery of this investigation.

The objective of this study was to develop a novel pilot-scale sludge electrodewatering (EDW) system using recessed plate filter press with no filter cloth and evaluate its performance on sewage dewatering. In this EDW device, a perforated stainless steel sheet was used as the electrodes and filter. An experimental design using the L9 orthogonal arrays based on the Taguchi Method was employed using the following factors of three levels: (1) mechanical dewatering time, (2) time of pseudo-secondary dewatering by compressed air, (3) electrodewatering time, and (4) intermittent change of applied electric field strength. The goal was to yield the optimal operating conditions to obtain sludge cakes of the lowest moisture content and the lowest extra energy consumption separately. Tests A and B were carried out by using the optimal operating conditions determined by the Taguchi Method representing the sludge cakes having the lowest moisture content and the lowest extra energy consumption, respectively. The magnitudes of moisture content and extra energy consumption associated with the sludge cakes obtained were given as follows: (1) 65.13% and 154.89 kWh/ton for Test A; and (2) 70.98% and 83.97 kWh/ton for Test B. Evidently, EDW is capable of lowering the moisture content of dewatered sludge. A further study on sludge disposal cost taking into account of the extra energy expenditure showed that it yielded a cost saving of 27-35% as a result of implanting EDW. In summary, the novel sludge electrodewatering system developed in this work is a viable technology with economic effectiveness.

Abstract:

The personal and national dimensions of terrorism victimhood lend the victims their unique moral authority and political legitimacy. The analysis of the news media coverage of victims' campaigns, on issues such as memorialization, criminal justice, hostage crises and peace activism, reveals that the more such campaigns are closer in time, space, and relevance to the attack that the victim-advocates underwent, the greater are their chances for positive coverage. Deferential coverage of victims' campaigns reflects journalism's cultural role as reinforcing common values and myths, including by way of portraying victims as heroes. Where victims' campaigns are less related to the physical memory of the attack and more concerned with the military or legal aspects of terrorism, journalists take on their informational role and employ traditional professional standards. Such standards include subjecting victims to potential criticism, and at the very least "balancing" their arguments with official views. In issues where the victims' arguments seem far removed from their personal experience, their influence over the news media is small. This range of journalistic notions is offered under the organizing mechanism of the Experience-Argument Scale. The two extreme ends of the Scale, the "deferential" end and the "disregarding" end, are where journalism's missions are in danger of compromise. Journalism at the "deferential" end is emotional, reluctant to bring forth opposing opinions, and in effect may contribute to policies that are driven more by trauma than by considered opinion. At the other end of the Scale, journalism is deaf to the victims, and fails to enrich policy debates with the lessons of their experience. The comparative examination of coverage in the U.S. and Israel illuminates the different relationships between press and government in these two cultures, and how local responses to victims reflect the particular local history of terrorism, and the particular notions of nationhood, solidarity and patriotism.

Background: Quadriceps strength training exercise has been shown to be effective in treating patellofemoral pain syndrome without relevant effective treatment strategies. It is suggested that the problem may not derive just from patellofemoral joint but alterd kinematic from proximal part.(hip and pelvic). According to recent studies, weakness of hip abductors and hip external rotator muscles was discovered in this population while quadriceps weakness was evident. However, if improved hip muscle strength are related to hip kinematics changes difference was interested in current study. Purpose: The first purpose was to compare the difference between leg press exercise(LPE) and additional hip abductor and external rotator muscle strength training to leg press exercise(LPE+HAE) in muscle strength, hip kinematics during step down, pain severity and function for patients diagnosed with patellofemoral pain syndrome. The second one was to discover the relationship between the change in muscle strength performance and the difference of hip joint kinematics post treatment. Methods: 85 individuals diagnosed with PFPS are randomized into 3 groups of intervention (leg press exercise(LPE), additional hip abductor and external rotator strength training to leg press exercise(LPE+HAE) and control). Tow exercise group received 8 weeks of 3 times per week strength training. Outcome measures were muscle strength (quadriceps, hip abductor, hip external rotator, hip internal rotator and hip extensor muscle strength) by hand-held dynamometry, hip joint kinematics during step down by electromagnetic motion tracking system (FASTRAK, Polhemus ), pain severity by PFPS pain severity scale (PSS), functional performance by Anterior Knee Pain Scale(AKP). All the tests mentioned above are measured at the baseline and after 8 weeks of treatment. Results: After 8 weeks of exercise intervention, patients with patellofemoral pain showed significant muscle strength improvements in knee extensors, hip abductors, and hip internal rotators, accompanied with significant reduction in pain(PSS) and functional improvements (Anterior knee pain scale)(p＜.005). Muscle strength performance in hip abductors, PSS and AKP demonstrated with statistical significance between each exercise group and control (p＜.008). There was no significant difference in hip kinematics performance after treatment while the change in hip internal rotation angle seems relevant larger in additional hip muscle strength training group (3°).When pooled the reduction in hip adduction and internal rotation angles and the improvement of every hip muscle strength of both exercise group post treatment, the change in hip abductor muscle group was correlated with change in hip internal rotation angle during stair decent(r=-.39. p＜.05). Conclusion: Both exercise groups demonstrated with significant improvement in muscle strength performance, pain severity and function. Even though there was no statistical significant difference in hip kinematic performance after 8 weeks of treatment, the improvement of hip abductor muscle strength and reduction in hip internal rotation angle were correlated. The relevant reduction in hip internal rotation angle of additional hip muscle strengthening group after treatment might suggest that additional hip muscle strength training may be helpful in reducing excessive hip internal rotation during stair decent.

Por este motivo, a presente dissertação apresenta-se como uma alternativa mais económica a obras de ampliação, sendo possível incrementar os rendimentos do processo de tratamento de águas residuais e industriais, quando comparado com os valores obtidos atualmente. Adicionalmente, este estudo permitiu aferir da importância que cada estágio/etapa tem bem como a forma como estes influenciam o processo e a qualidade do tratamento das águas residuais e industriais.Algumas das etapas do presente trabalho encontram-se descritas de um modo breve por forma a assegurar a confidencialidade requerida pela empresa.
The work was carried out at the Waste and Industrial Water Treatment Plant (ETARI), of SRAM Portugal, under the guidance of Eng. Alexandra Fortunato, responsible for the environment, safety and infrastructure, and supervision of Profa. Dr. Ana Paula Piedade, professor at the University of Coimbra, having started on 01.03.2021 and ended on 30.06.2021, totalling a duration of 4 months. The main objective of this document deals with the dimensioning of the ETARI for current and future needs (if there is an increase in the factory) and also the optimization of the physical-chemical process, as well as possible improvements in infrastructure.It is also important to mention that all the measures proposed in this document result from the experience with the daily problems that arise at the ETARI facilities. Within the time frame referred to in this document, it was thus possible to suggest changes to be made to the ETARI, without having to resort to its expansion. For this reason, the approaches and solutions presented in this dissertation are a more economical alternative to expansion works, being possible to increase the yields of the wastewater and industrial water treatment process, when compared to the values currently obtained. Additionally, this study allowed to assess the importance of each stage as well as how they influence the process and quality of wastewater and industrial water treatment.Some of the steps of this work are briefly described in order to ensure the confidentiality required by the company.
