The institutional design of intra-party democracy through legal instruments: Turkish case

The importance of political parties for contemporary representative democracies is beyond dispute. Despite their significance for state-level democracy, political parties continue to be regarded as oligarchical and to be criticised because of their internal practices. For this reason, intra-party democracy (IPD) warrants in-depth analysis. This thesis investigates IPD in Turkey, primarily from the perspective of participatory democracy, with the purpose of suggesting reforms to the Turkish Political Parties Law (TPPL). Turkish political parties and Turkish party regulation provide an interesting case because there is a significant difference between mature democracies and Turkey regarding IPD regulation. IPD in established democracies has always been regarded as a private concern of parties and has been left unregulated. IPD in Turkey, by contrast, is provided for both by the constitution and the TPPL. Although IPD is a constitutional and legal requirement in Turkey, however, political parties in fact display a high level of non-democratic administration. The main reason is that the TPPL only pays lip service to the idea of IPD and requires no specific measures apart from establishing a party congress with a representative form of democracy. By establishing and holding party congresses, political parties are perceived as conforming to the requirements of IPD under the law. In addition, the contested nature of democracy as a concept has impeded the creation of efficacious legal principles. Thus, the existing party law fails to tackle the lack of IPD within political parties and, for this reason, is in need of reform. Furthermore, almost every Turkish party’s own constitution highlights the importance of IPD and promises IPD. However, these declared commitments to IPD in their constitutions alone, especially in countries where the democratic culture is weak, are unlikely to make much difference in practice. Accordingly, external regulation is necessary to ensure the protection of the rights and interests of the party members with regards to their participation in intra-party decision-making processes. Nevertheless, in spite of a general consensus in favour of reforming the TPPL, a lack of consensus exists as to what kind of reforms should be adopted. This thesis proposes that reforming the TPPL in line with an approach based on participatory democracy could provide better IPD within Turkish political parties, citing as evidence comparative case studies of the participatory practices for policy-making, leadership selection and candidate selection in mature democracies. This thesis also analyses membership registration and the effect of state funding on IPD, which are highly problematic in Turkey and represent impediments to the flourishing of IPD.

Intra-pulse transition between ion acceleration mechanisms in intense laser-foil interactions

Multiple ion acceleration mechanisms can occur when an ultrathin foil is irradiated with an intense laser pulse, with the dominant mechanism changing over the course of the interaction. Measurement of the spatial-intensity distribution of the beam of energetic protons is used to investigate the transition from radiation pressure acceleration to transparency-driven processes. It is shown numerically that radiation pressure drives an increased expansion of the target ions within the spatial extent of the laser focal spot, which induces a radial deflection of relatively low energy sheath-accelerated protons to form an annular distribution. Through variation of the target foil thickness, the opening angle of the ring is shown to be correlated to the point in time transparency occurs during the interaction and is maximized when it occurs at the peak of the laser intensity profile. Corresponding experimental measurements of the ring size variation with target thickness exhibit the same trends and provide insight into the intra-pulse laser-plasma evolution.

Delivery of nucleic acids for cancer gene therapy: overcoming extra- and intra-cellular barriers

The therapeutic potential of cancer gene therapy has been limited by the difficulty of delivering genetic material to target sites. Various biological and molecular barriers exist which need to be overcome before effective nonviral delivery systems can be applied successfully in oncology. Herein, various barriers are described and strategies to circumvent such obstacles are discussed, considering both the extracellular and intracellular setting. Development of multifunctional delivery systems holds much promise for the progression of gene delivery, and a growing body of evidence supports this approach involving rational design of vectors, with a unique molecular architecture. In addition, the potential application of composite gene delivery platforms is highlighted which may provide an alternative delivery strategy to traditional systemic administration.

Avaliação in vitro da capacidade de selamento de diferentes materiais usados como barreiras intra-coronal

Introdução: O adequado selamento do sistema de canais radiculatres (SCR) obtido através da obturação, evita a infiltração de micro-organismos entre as paredes do canal radicular e o material obturador, reduzindo a possibilidade de insucesso do tratamento endodôntico (TE). A falta de selamento coronal, o atraso da colocação da restauração permanente, a fratura da restauração coronal, assim como uma espessura inadequada da restauração provisória, inferior a 4mm, podem, entre outros factores, ser predisponentes para a recontaminação do SCR obturado. Sendo o selamento da entrada do SCR uma importante etapa do TE, neste estudo pretendeu-se avaliar diferentes materiais para tal procedimento, avaliando qual o material que proporciona menor infiltração. Materiais e métodos: Neste estudo foram utilizados 70 dentes humanos monocanalares, que foram divididos aleatoriamente em 6 grupos. Grupo I (15 dentes) foram selados com ionómero de vidro modificado por resina (Ionoseal - VOCO®), Grupo II (15 dentes) foram selados com ionómero de vidro modicifado por resina (GC Fuji II LC- GA America®), Grupo III (15 dentes) foram selados por um compósito fluído (GrandioSO Heavy Flow - VOCO®), Grupo IV (15 dentes) foram selados por um compósito nanohíbrido (GrandioSO - VOCO®). O Grupo V (5 dentes) e o Grupo VI (5 dentes) foram usados como controlo negativo e positivo, respectivamente. Os dentes foram submetidos a termociclagem de 500 ciclos, de 60 segundos de duração cada um, com variações de temperatura de 5°C - 55°C. Em seguida, foram imersos em corante azul de metileno a 2% para avaliação da infiltração dos materiais. Resultados: Em geral, Ionoseal® demonstrou maior infiltração de corante que os outros materiais, e quando comparado com os demais grupos a diferença foi significativa. Porem entre os grupos 1, 2 e 3 não houve diferença estatística significante. Conclusões: LC Fuji II®, GrandioSo® Nano partícula Flow e GrandioSo® Nano partícula podem ser usados como barreira intracanalar.

A Ortodontia e aparelhos intra orais no tratamento da SAHOS (Sindrome da Apneia e Hipopneia Obstrutiva do Sono)

A síndrome da apneia e hipopneia obstrutiva do sono (SAHOS) é uma patologia que atinge cerca de 4% da população adulta, é uma doença crónica, progressiva, com alta morbilidade e mortalidade. A apneia do sono e o ronco têm despertado a atenção da área da saúde devido às inúmeras comorbilidades associadas. Esta síndrome é caracterizada por obstrução parcial ou total das vias aéreas superiores durante o sono e manifesta-se como uma redução (hipopneia) ou cessação (apneia) do fluxo aéreo. A queixa habitual dos pacientes além dos problemas sociais como ronco e a hipersonolência diurna, são a preocupação com outros quadros que esta patologia pode desencadear, como insuficiência cardíaca e hipertensão pulmonar. O tratamento da apneia obstrutiva do sono é multidisciplinar e indispensável, podendo ser realizado de diversas formas, tanto conservadoras como cirúrgicas, dependendo de inúmeros fatores como a gravidade da doença, as alterações anatómicas das vias aéreas superiores, idade e condições sistémicas do paciente. Os aparelhos intra orais têm sido usados durante anos, no tratamento da SAHOS como controle da obstrução das vias aéreas superiores. A terapia com aparelhos intraorais é simples e reversível. O sucesso do tratamento com aparelhos intra orais para o ronco e SAHOS leve e moderada é comprovado pela grande maioria dos estudos. A facilidade de uso, manutenção e conforto quando comparados a outros tratamentos faz com que os aparelhos intrabucais sejam considerados de fácil aceitação pelos pacientes. Através de uma revisão de literatura discutiu-se o uso de aparelhos intrabucais para o tratamento dessa patologia, destacando a eficácia e as limitações dessa terapia, os principais sintomas clínicos, os principais efeitos colaterais oclusais, o grau de colaboração e o índice de satisfação dos pacientes. Foi possível concluir que aparelhos intrabucais de avanço mandibular estão amplamente indicados para o tratamento do ronco e da SAHOS como terapia principal, ou alternativa naqueles pacientes que não podem suportar a terapia da pressão positiva das vias aéreas e que para o sucesso do tratamento é fundamental uma equipe multidisciplinar, incluindo um Médico Dentista e a colaboração do paciente.

Diagnosis of intra-abdominal injuries can be challenging in multitrauma patients with associated injuries. Our experience and review of the literature

ntroduction. Trauma is the most common cause of death and disability among patients during the first four decades of life. Abdominal trauma is reported to be the 3rd most common injured region. Clinical examination may be unreliable in the evaluation of these patients especially in the presence of associated injuries. Therefore the use of diagnostic tools is essential in the management of the injured patient with abdominal trauma and additional injuries. Patients and Methods. During 1 year period from December 2010 to November 2011 we recorded the patients that presented to the emergency department of our hospital and were found to suffer from intra-abdominal injuries. These patients were divided in two groups depending on whether they had additional comorbid injuries or not. Several parameters were recorded and compared between the two groups, such as mechanism of injury, general status and hemodynamic stability of the patient on presentation, physical examination, use of imaging modalities and concomitant findings, need for surgical intervention and mortality rates. Furthermore the discrepancy between physical findings and final diagnosis after the use of diagnostic adjuncts is reported. Results. We recorded 31 patients with abdominal trauma. 13 (42%) patients were found to suffer from abdominal trauma and associated injuries (Group I), whereas 18 (58%) presented with abdominal trauma alone (Group II). The patients of the first group presented hemodynamic instability in 38% of cases while the patients of the second in 22% of cases. Reduced consciousness was present in 38% in group I versus 17% in group II. Signs of abdominal injury during clinical examination were present in only 15% in group I versus 72% in group II that represented a remarkable difference between the two groups. Conservative treatment was possible in 15% of patients with additional injuries and in 22% of patients with abdominal injury alone. In group I there were two deaths whereas in group II all patients survived. Conclusion. In patients with abdominal trauma, associated injuries seem to add to the severity of injury and indicate a worse prognosis. Clinical examination is unreliable and misleading in the majority of these patients and the use of diagnostic tools cannot be overemphasized.

Caminhos que estruturam cidades: redes técnicas de transporte sobre trilhos e a conformação intra-urbana de Natal

The railroad, from 1870 and on, becomes an usual complaining in the press s and politician elite s speeches, especially because of Natal s geographic isolation. The implantation of two railroads in the capital territory Estrada de Ferro de Natal a Nova Cruz, afterwards part of Great Western Railway Company network, and Estrada de Ferro Central do Rio Grande do Norte had serious implications in the urban environment. While railroad s structures were already consolidated, other transportation mechanisms were being implanted in the first decades of the 20th century, such as trams lines, which, by the way, was a transport modal that also used rails as a dislocation meaning. Considering these questions, we may ask: how come railroads and tramways demands, roads and buildings had influenced the internal organization of Natal? We work with the general hypothesis that the influence of technical networks, composed by tramways and railroads, over Natal s urban space happened in a diversified way, sometimes consolidating social aspects in certain areas, sometimes improving the occupation of others. The impact over the city s territory also happens in a diversified way between the buildings/railroad s complexes and the pathways. The different scale of the train in comparison to the trams velocity, size, noise level, flow, among others is also a cause to the different consequences in urban environment. The main objective of this work is to understand the role of circulation technical networks in the construction process of urban space in Natal, as a way to contribute to the urban historiography about the subject. The time frame adopted, between 1881 and 1937, marks the time path of railroads and tramways in Rio Grande do Norte: 1881 is the year of railroad s first section inauguration from Natal to São José do Mipibu as well of the railroad complex in the Republic Square in Natal; the year of 1937 marks the beginning of tramways declination process in the city. At this time railroads and tramways had to face more intensively the competition of motor vehicles. The theory reference adopted is based on concepts and analysis of authors, such as Flávio Villaça and Roberto Lobato Corrêa references to the concepts of urban structure , localization and accessibility and Gabriel Dupuy to explain the concept of urban technical networks . These references reveal the conflict of different realities in the urban universe interests and values which is an important factor about the construction of urban space. The information sources used were from two distinctive natures: primary, journals of the time studied and official government reports, and secondary, based on other works about the subject. It was also used by this study iconographic source, especially images from the data base of the research group História da Cidade, do Território e do Urbanismo .

Hipertensión intra-abdominal y síndrome abdominal compartamental prevalencia postlaparotomía por abdomen agudo, HVCM Cuenca 2010-2011 /

La hipertensión intra-abdominal (HIA) y el síndrome compartamental abdominal (SCA) son causa importante de morbi-mortalidad postoperatoria. Avances en su diagnóstico y tratamiento oportuno han proporcionado mejor sobrevida en estos pacientes. Objetivo. Determinar la prevalencia de HIA, SCA y asociarla con (hallazgos quirúrgicos, presión de perfusión Intra-abdominal (PPI), obesidad) intervenidos por abdomen agudo en el Departamento de Cirugía del Hospital Vicente Corral Moscoso de Cuenca. Metodología. Se realizó un estudio transversal analítico en pacientes mayores de 16 años que ameritaron laparotomía de septiembre de 2010 hasta agosto de 2011 y que cumplieron criterios de exclusión, la PIA fue medida mediante método indirecto y la información se recopilo en un formulario elaborado para el estudio. Resultados: 347 Pacientes fueron incluidos en el estudio, la media de edad se ubicó en 46.72 ± 22.30 años, presentaron sobrepeso el 5.2%, en el estadio pre-quirúrgico se encontró Hipertensión Intra-abdominal en 41.2% y 10.4% de síndrome compartamental; luego de la laparotomía la hipertensión intra-abdominal disminuyó a 37.7% y el síndrome compartamental a 8.4%. La PIA iguales o mayores a 12mmHg aumentan el riesgo de hipo-perfusión intestinal en 3.56 veces (IC 95%: 1.81-6.99), p menor que 0.05; la obesidad se comportó como factor de riesgo con un RP de 1.73 (1.451-2.13); los hallazgo quirúrgico encontrados fueron significativos para Abdomen agudo perforativo: 2.45 con IC 95% 1.91-3.13; Abdomen agudo hemorrágico 1.83 con IC 95% 1.46-2.30 y Abdomen agudo oclusivo intestinal 2.32 con IC 95% 2.05-2.64. Conclusión: La Hipertensión intra-abdominal disminuye progresivamente en el postoperatorio, mientras que en quienes se manifiesta el SCA permaneció elevado por mayor tiempo. Se evidencio que la Obesidad influye incrementando la PIA, la misma que produce disminución de la PPI prediciendo peor pronóstico; los hallazgos quirúrgicos representativos para el incremento de la PIA fueron el abdomen agudo perforativo y oclusivo .au

EXPLORING THE EFFECTS OF THE RELATIONSHIP BETWEEN SCHOOL CHARACTERISTICS, TEACHER CHARACTERISTICS, ADMINISTRATIVE SUPPORT, AND SCHOOL CLIMATE ON VOLUNTARY INTRA-DISTRICT TEACHER MIGRATION

This quantitative research study utilized a binary logistic regression in a block design to investigate exogenous and endogenous factors influencing a teacher’s decision to make an intra-district move. The research focused on the following exogenous factors: classroom characteristics (size of class, percent minority, percent of students with an individualized education plan, and percent of students that are English language learners) and teacher characteristics (experience and gender). The following endogenous factors were examined: direct administrative influence (administrative support, rules enforced, school vision, teacher recognition, and job security) and indirect administrative influence (school climate, student misbehavior, parental support, materials, staff collaboration). The research was conducted by using information available from the National Center for Educational Statistics, the SASS from 2011-2012 and TFS from 2012-2013. The 2012-2013 Teacher Follow-up Survey identified 60 teachers who made a voluntary intra-district move. Results illustrate there is a statistically significant relationship between percentage of English Language Learners and overall job satisfaction and teachers choosing to make an intra-district move.

Sources de variation intra-populationelle de la morphologie des otolithes: asymétrie directionnelle et régime alimentaire

Otoliths are calcified structures located in Osteichthyes’ inner ear that are involved in audition and balance. Their morphology is used as an indicator of various ecological processes or properties. This application requires identifying the endogenous and exogenous factors that act simultaneously as sources of shape variation. This thesis aims at detecting and quantifying the relative contributions of directional asymmetry and diet to otolith shape variation at the intra-population level. Directional asymmetry between left and right otoliths was found in flat-fishes, the blind-side otolith being always longer and larger, whereas it was negligible in round-fishes. However, asymmetry amplitude never exceeded 18 %, which suggests evolutionary canalization of otolith shape symmetry. A correlation between global diet and otolith was detected in 4 species studied in situ. Diet composition contributed more than food amount to morphological variation and affected otolith shape both globally and locally. An experimental study on sea bass (Dicentrarchus larbrax) showed that diet composition in terms of essential polyunsaturated fatty acids at larval stage affects otolith morphogenesis during juvenile stage without impacting on individuals’ somatic growth. This result suggests a direct effect of diet on otolith shape and not an indirect one through the somatic-otolith growth relationship. This effect disappeared at later stages, morphogenetic trajectories converging back to a similar shape, which suggests ontogenetic canalization of otolith shape.
