Objetivo: describir y analizar la percepción sobre factores predisponentes a Infecciones Respiratorias Agudas en madres de preescolares de una comunidad de Pomalca. Método: Investigación cualitativa, descriptiva, en una muestra de 12 madres de preescolares de la comunidad el Combo, determinada por saturación y redundancia de datos, el muestreo fue no probabilístico por conveniencia. Los datos se recolectaron a través de la entrevista semiestructurada, la cual fue validada por juicio de expertos y por una prueba piloto en 2 madres que cumplían con los criterios de inclusión. Los datos fueron procesados por el método de análisis de contenido temático. Resultados: Se obtuvieron 4 categorías: identificación de factores individuales, reconocimiento de factores en la vivienda, asimismo, identificación de los factores familiares y reconocimiento de factores ambientales como factor predisponente. Conclusión: En su mayoría, las madres de familia tienen una percepción adecuada y reconocen los diversos factores que predisponen a presentar una IRA en los menores de 5 años. Reconocen de manera correcta dentro de los factores familiares, la presencia de algún familiar fumador debido a las sustancias tóxicas que pueden inhalar los preescolares; pero existe una percepción incorrecta sobre la asociación del fumador pasivo (inhala el humo del cigarrillo) con presentar TBC. / Objective: to describe and analyze the perception of predisposing factors to Acute Respiratory Infections in mothers of preschoolers in a community of Pomalca. Method: Qualitative, descriptive research, in a sample of 12 mothers of preschoolers from the Combo community, determined by data saturation and redundancy, sampling was non-probabilistic for convenience. The data were collected through a semi-structured interview, which was validated by expert judgment and by a pilot test on 2 mothers who met the inclusion criteria. The data were processed by the thematic content analysis method. Results: 4 categories were obtained: identification of individual factors, recognition of factors in the home, also, identification of family factors and recognition of environmental factors as a predisposing factor. Conclusion: For the most part, mothers have an adequate perception and recognize the various factors that predispose children under 5 years of age to having an ARI. They correctly recognize within family factors, the presence of a family member who smokes due to the toxic substances that preschoolers can inhale; But there is an incorrect perception about the association of passive smoking (inhaling cigarette smoke) with developing TB.

Face à la diminution croissante des ressources d'origine fossile, une attention particulière est portée depuis plusieurs années envers l'utilisation de ressources renouvelables. Dans ce contexte, beaucoup de recherches sont orientées vers l'utilisation de polysaccharides tels que la cellulose. L'intérêt de ces composés est qu'ils sont abondants, peu chers et biodégradables. A l'inverse, ces polymères possèdent une faible résistance mécanique limitant ainsi leurs applications. De manière à moduler les propriétés de ces polymères, une alternative consiste à les modifier chimiquement par greffage de chaînes de polymères synthétiques. Néanmoins, les stratégies de greffage décrites dans la littérature présentent certaines limitations notamment sur la facilité de mise en oeuvre, la toxicité des méthodes employées, le nombre d'étapes de synthèses ou encore le contrôle des masses molaires. Par ailleurs, la caractérisation de ces architectures complexes reste délicate notamment pour prouver le greffage covalent des chaînes de polymère sur le polysaccharide. C'est précisément dans cet axe de recherche que s'insère ce sujet de thèse. Plus particulièrement, l'objectif principal consiste à mettre au point une méthode de greffage de l'acétate de cellulose robuste et facile à mettre en oeuvre, en vue d'une utilisation potentielle en tant que compatibilisant de mélange de polystyrène et d'acétate de cellulose. Afin d'atteindre cet objectif, notre stratégie a consisté à utiliser la polymérisation radicalaire contrôlée par les nitroxydes (NMP) où une attention particulière a été portée sur la caractérisation structurale des matériaux synthétisés (RMN du solide et DOSY, RPE, CES, DLS et DSC). / In order to respond to the fossil resources depletion, a particular attention was paid to the use of renewable resources since several years. In this context, many researches focus on the use of polysaccharides such as cellulose. These compounds are attractive because of their abundance, low cost and biodegradability. On the other hand, these polymers suffer from weak mechanical resistance limiting their practical applications. Grafting synthetic polymers chains on these natural polymers is an alternative to this problem. Nevertheless, grafting strategies described in the literature involve certain limitations such as the difficulty of implementation, the toxicity of the used methods, the great number of synthesis steps or the control of molar mass. Moreover, the characterization of these complex architectures remains delicate in order to prove the covalent grafting of chains on the polysaccharide. In line with this research context, the topic of this thesis concerns the development of a robust method for cellulose acetate polymer grafting. Moreover, the selected method has to be easy to implement, with a possible application as a compatibilizer for blending of polystyrene and cellulose acetate. In order to achieve this purpose, our strategy is based on the use of Nitroxide-Mediated Polymerization (NMP) where particular attention was paid to the structural characterization of synthesized materials (solid state NMR, DOSY NMR, ESR, SEC of grafts, DLS and DSC).

UNIVERZITA KARLOVA V PRAZE FAKULTA SOCIÁLNÍCH VĚD Institut politologických studií Eliška Vyšatová Praha 2014 Diploma thesis: The Functioning of national-separatist organizations. A Comparative study of the IRA and ETA Abstract: The diploma thesis "The Functioning of National-Separatist Organizations. A Comparative Study of IRA and ETA" deals with two West European national-separatist organizations as well as the phenomenon of political terrorism and ethnic conflict. The selected organizations are unique among other ones as to their history and the way of functioning, and for these reasons they have been chosen for this study. Both organizations can be considered the main source of conflict in the national separatist movement in Basque Country and Northern Ireland from the beginning of the 20th century. The basic premise is that both IRA and ETA reach their aim, which can be generalised as independence of the national states, which they are a part of, in a specific way, it being primarily terrorism. The main aim of this paper is to compare various aspects of functioning of IRA and ETA and, on the basis of these results, to evaluate if we can consider these as two organizations different from other groups of this kind as well as different from each other, although they demonstrate some similar...

The Irish peace process is heralded as a success among insurgencies that attempt transitions toward peaceful resolution of conflict. After thirty years of armed struggle, pitting Irish republicans against their loyalist counterparts and the British State, the North of Ireland has a reconfigured political landscape with a consociational governing body where power is shared among several parties that hold divergent political objectives. The Irish Republican Movement, whose main components are the Provisional Irish Republican Army, a covert guerilla armed organization, and Sinn Fein, the political party of Irish republicans, initiated peace that led to all-inclusive talks in the 1990s and that culminated in the signing of the Good Friday Agreement in April 1998, setting out the parameters for a non-violent way forward. Given the traditional intransigence of the IRA to consider any route other than armed conflict, how did the leadership of the Irish Republican Movement secure the support of a majority of republicans for a peace initiative that has held now for more than fifteen years? This dissertation explores the dynamics of leadership in this group, and in particular, focuses on the prisoner resistance waged by its incarcerated activists and volunteers. It is the contention here, that various prisoner resistance tactics enabled a wide-ranging group of captives to develop the skill set necessary to persuade their community to back the peace initiative, engage in electoral politics, mobilize their supporters to invest in attaining a united Ireland by peaceful negotiations, and put down their arms in a permanent and unequivocal manner. In this dissertation, the work of Paulo Freire is explored in order to capture the processes inherent the resistance-leadership continuum.

O presente trabalho analisa o impacto do treinamento desportivo e competições sobre a incidência e duração de IRA em atletas de natação do clube Associação dos Docentes da Escola Superior de Educação Física do Pará (ADESEF-PA), Belém, Pará, no período de janeiro a junho do ano de 2004. Para isso, dezoito atletas de natação de ambos os sexos, das categorias infantil (13 e 14 anos), juvenil (15 e 16 anos) e júnior (17 e 18 anos) foram acompanhados durante um período de treinamento de 24 semanas visando às disputas do campeonato brasileiro de natação das referidas categorias. A partir do macrociclo foram obtidos os dados a respeito do volume de treinamento e o número de competições disputadas. Através de uma ficha clínico-epidemiológica, levantando a ocorrência de sinais e sintomas sugestivos de gripe e resfriado, registrou-se o número e a duração dos episódios de IRA. Os resultados deste estudo revelaram uma ocorrência freqüente de IRA no grupo de atletas estudado e ausência de imunidade prévia por vacina anti-Influenza. A incidência (61,1%) e a duração média total (9,5 dias) dos episódios de IRA não diferiu entre os sexos, categorias e períodos do treinamento desportivo. Identificou-se ainda uma importante proporção de recorrência dos episódios de IRA nos atletas acompanhados. As infecções respiratórias apresentaram um perfil clínico compatível com a gripe, sugerindo que o vírus Influenza parece constituir o principal agente etiológico das infecções respiratórias apresentadas pelos atletas estudados. A partir dos resultados obtidos no estudo, concluiu-se que tanto a incidência quanto a duração dos episódios de IRA não foram influenciadas pelo volume de treinamento e número de competições aos quais os atletas foram expostos. / The physiologic stress exercise-induced can to raise the susceptibility of athletes to acute respiratory infections. This work evaluate the impact of training and matches competitions on incidence and duration of acute respiratory infections in swimmers of the “Associação dos Docentes da Escola Superior de Educação Física do Pará" team, Belém, Pará, of january to june of 2004. Follow up eighteen swimmers of both sex, including infantile (13 and 14 years), juvenile (15 and 16 years) and junior (17 and 18 years) categories during 24 weeks of training season to aim at the matches of swimming Brazilian championship in this categories. The volume training and number matched competitions were registered. Using a clinic and epidemiologic questionary to survey the occurrence of signs and symptoms suggesting of flu and cold, we registered the number and time of respiratory infection episodes. The incidence (61,1%) and durations (9,5 days) of acute respiratory infections don’t were differ between sex, categories ands seasons of training. Identify frequently searching of the respiratory infections episodes in the followed up athletes. A clinic profile of respiratory infections, like flu, was observed, suggesting that Influenza virus appear to constitute the major etiologic agent of the respiratory infections presented by studied athletes. The results of study we conclude that incidence and durations of acute respiratory infections don’t were altered by volume training and number of competitions.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O presente trabalho propÃe investigar a ira na Hecyra (160 a.C.) de TerÃncio (185-159 a.C.) por meio de uma leitura estoica. A delimitaÃÃo desse corpus de anÃlise decorre da significativa recorrÃncia na peÃa de um campo lexical atrelado à noÃÃo de ira (ira, iniuria, iniquitas), em especial em episÃdios que envolvem os senes Laques e Fidipo. Julgando possÃvel examinar a presenÃa da ira na Hecyra por um prisma estoico, nosso objetivo à analisar a peÃa à luz da teoria das paixÃes. Para atingir esse objetivo, elaboramos uma pesquisa bibliogrÃfica e entÃo estudamos textos filosÃficos que discutam a teoria das paixÃes, principalmente à luz do estoicismo, em seguida aplicamos os resultados obtidos Ãs hipÃteses de nossa pesquisa e realizamos uma anÃlise mais fundamentada do texto de TerÃncio. Para desenvolver esta pesquisa, utilizamos como fundamentaÃÃo teÃrica em especial obras filosÃficas que discutam a teoria das paixÃes, sobretudo a ira, como Rhetorica e Ethica Nicomachea, de AristÃteles, Tusculanae disputationes, de CÃcero, e De ira, de SÃneca. AlÃm de textos antigos, tambÃm utilizamos estudos modernos a respeitos da teoria das paixÃes, como os de Martha C. Nussbaum e Margareth Graver. Na IntroduÃÃo, comentamos a relaÃÃo do teatro com a filosofia e como essa relaÃÃo se dava desde Menandro, contextualizamos TerÃncio e sua obra e discutimos a relaÃÃo de seu teatro com a filosofia e sua presenÃa no CÃrculo dos CipiÃes; no capÃtulo seguinte, apresentamos a teoria das paixÃes e a concepÃÃo de ira nas escolas peripatÃtica e estoica; no terceiro capÃtulo, analisamos a presenÃa de um lÃxico vinculado à noÃÃo de ira na Hecyra à luz do estoicismo. Esperamos, ao fim desta investigaÃÃo, descortinar um pouco mais o diÃlogo da literatura com a filosofia e o teatro de TerÃncio, em particular a Hecyra. / The present work proposes to investigate anger in Hecyra (160 BC), play by Terence (185- 159 BC), through a Stoic reading. The delimitation of analysis corpus stems from a significant recurrence of a lexical field linked to the anger notion (ira, iniuria, iniquitas) in the play, especially in episodes that involve the senes Laques and Fidipo. Judging the possibility to examine the presence of anger in Hecyra by a Stoic prism, our aim is to analyze the play in light of Theory of the Passions. To reach this goal, we elaborate a bibliographical research and then study philosophical texts that discuss the Theory of the Passions, mainly in the light of stoicism, then apply the results obtained to our research hypothesis and make a more reasoned analysis of Terenceâs text. To develop this research, we use as theoretical foundation, especially philosophical works, that discuss the Theory of Passions, especially Anger, such as Rhetorica and Ethica Nicomachea, by Aristotle, Tusculanae disputationes, by Cicero, and De ira by Seneca. In addition to ancient texts, we also use modern studies concerning the theory of passions, such as Martha C. Nussbaum and Margareth Graver. In the Introduction section, we comment on the relationship between theater and philosophy and how this relationship was given since Menander, we contextualize Terence and his work, discuss his theater relationship with philosophy, and his presence in the Scipionic Circle; in the following chapter, we present the theory of passions, the conception of anger in both peripatetic and stoic schools; in the third chapter, we analyze the presence of a lexicon linked to the notion of anger in Hecyra in the light of Stoicism. We hope, at the end of this investigation, to discover a little more on the dialogue of literature with philosophy and theater by Terence, in particular Hecyra. .

Society’s dependence on electronic and electrical systems has increased rapidly over the past few decades, and people are relying more and more on these gadgets in their daily life because of the efficiency in operation which these systems can offer. This has revolutionized many areas of electrical and electronics engineering including power sector, telecommunication sector, transportation and many other allied areas. With progress in time, the sophistication in the systems also increased. Also as the systems size reduced from micro level to nano level, the compactness of the systems increased. This paved the way for development in the digital electronics leading to new and efficient IC 0s that came into existence. Power sector also faced a resurge in its technology. Most of the analog meters are now replaced by digital meters. The increased sophistication and compactness in the digital system technology made it susceptible to electromagnetic interference especially from High Power Electromagnetic Sources. Communication, data processing, sensors, and similar electronic devices are vital parts of the modern technological environment. Damage or failures in these devices could lead to technical or financial disasters as well as injuries or the loss of life. Electromagnetic Interference (EMI) can be explained as any malicious generation of electromagnetic energy introducing noise or signals into electric and electronic systems, thus disrupting, confusing or damaging these systems. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. These effects can range from a simple degradation of data to a total loss of data. The source may be any object, artificial or natural, that carries rapidly changing electrical currents, such as an electrical circuit. The sources of electromagnetic interference can be either unintentional or intentional. The sources producing electromagnetic interference can be of different power levels, different frequency of operation and of different field strength. One such classification of these sources are the High Power Electromagnetic Sources (HPEM) High Power Electromagnetic environment refers to sources producing very high peak electromagnetic fields at very high power levels. These power levels coupled with the extremely high magnitude of the fields are sufficient to cause disastrous effects on the electrical and electronic systems. There has been a lot of developments in the field of the source technology of HPEM sources so that they are now one of the strongest sources of electromagnetic interference. High Power Electromagnetic environment refers to the sources producing very high peak electromagnetic fields at very high power levels. These power levels coupled with the extremely high magnitude of the fields are sufficient to cause disastrous effects on the electrical and electronic systems. HPEM environments are categorized based on the source characteristics such as the peak electric field, often called threat level, frequency coverage or bandwidth, average power density and energy content. The sources of electromagnetic interference can be either unintentional or intentional. Some examples of unintentional sources are the increased use of electromagnetic spectrum which generates disturbance to various systems operating in that frequency band, poor design of systems without taking care of other systems present nearby as well as lightning. Intentional sources are High altitude Electromagnetic Pulse (HEMP) or Nuclear Electromagnetic Pulse (NEMP) due to nuclear detonations, Ultra Wide Band (UWB) field from Impulse Radiating Antennas (IRA), Nar-row band fields like those coming from High Power Microwaves (HPM), High Intensity Radio Frequency (HIRF) sources. Of these the lightning is natural and all other sources are man-made. The significant progress in the Intentional High-Power Electromagnetic (HPEM) sources and antenna technologies and the easy access to simple HPEM systems for anyone entail the need to determine the susceptibility of electronic equipment as well as coupling of these fields with systems such as cables (buried as well as aerial), airborne vehicle etc. to these types of threats. Buried cables are widely used in the communication and power sectors due to their efficient functioning in urban cities and towns. These cables are more prone to electromagnetic interferences from HPEM sources. The buried communication cables or even the buried data cables are connected to sensitive equipments and hence even a slight rise in the voltage or the current at the terminals of the equipments can become a serious problem for the smooth operation of the system. In the first part of the thesis the effect of the electromagnetic field due to these sources on the cables laid underground has been studied. The second part of this thesis deals with the study of the interaction of the EM field from the above mentioned HPEM sources with an airborne vehicle. Airborne vehicle and its payload are extremely expensive so that any destruction to these as a result of the voltages and currents induced on the vehicle on account of the incoming HPEM fields can be quite undesirable. The incoming electromagnetic fields will illuminate the vehicle along its axis which results in the induction of currents and voltages. These currents and voltages will get coupled to the internal control circuits that are extremely sensitive. If the induced voltage/ current magnitude happen to be above the damage threshold level of these circuits then it will result in either a malfunction of the circuit or a permanent damage of it, with both of them being detrimental to the success of the mission. This will even result in the abortion of the mission or possible degradation of the vehicle performance. Hence it is worthwhile to see what will be the influence of an incoming HPEM electromagnetic field on the airborne vehicle with and without the presence of an exhaust plume. In this work, the HPEM sources considered are NEMP, IRA and HPM. The electromagnetic fields produced by the EMP can induce large voltage and current transients in electrical and electronic circuits which can lead to a possible malfunction or permanent damage of the systems. The electric field at the earth 0s surface can be modelled as a double exponential pulse as per the IEC standard 61000-2-9. The NEMP field incident on the earth’s surface is considered as that coming from a source at a distance far away from the earth’s surface; hence a plane wave approximation has been used. Impulse radiating antennas are the ones that are used as the major source of ultra wide band radiation. These are highly powerful antennas that use a pulsed power source as the input and this power source is conditioned to get an extremely sharp rise time pulse. These antennas are very high power antennas that are capable of producing a significant electromagnetic field. Impulse radiating antenna is a paraboloidal reflector and hence is an aperture antenna. Initially the radiated field due to this aperture needs to be found out at any observation point from the antenna. In this thesis, the aperture distribution method is used to accurately determine the field due to the aperture. In this method the field reflected from the surface of the reflector is first found on an imaginary plane through the focal point of the reflector that is normal to the axis of the reflector, by using the principles of geometrical optics, which then is extended to the observation point. The IRA considered for the present work is the one of the most powerful IRA as per the published literature available in the open domain. This has an input voltage of 1.025 MV. The far field electric field measured at the boresight (at r =85 m) being equal to 62 kV/m, and the uncorrected pulse rise time (10%-90%) is 180 ps for this IRA. HPM sources are usually electromagnetic radiators having a reflector with a horn antenna kept at their focal point for excitation. HPM sources generally operate in single mode or at tens or hundreds of Hz repetition rates. Many HPM radiators are developed in the world each with their own peculiar geometry and power levels. In the present thesis, a single waveguide (WR-975) fed HPM antenna assembly has been studied. The chosen waveguide has a cut-o_ frequency of 1 GHz and a power level of 10 GW. The wavelength associated with the waveguide is 0.3 m. The field pattern shows a definite peak in its response when the frequency is 1 GHz, the cut-off frequency of the waveguide. The electric field coming out of the HPEM sources travel through the medium that is either air alone or a combination of air and soil respectively depending upon whether the circuit on which the coupling is analysed is an airborne vehicle or an underground cable. The media plays a major role in the coupling, as the field magnitude is influenced by the characteristic properties of the media. As height increases the magnitude of the electric field decreases for all types of sources and also the time before which the field waveform starts is increased. The electric field in the soil is decided by the soil properties such as its conductivity and permittivity. The soil is modelled in frequency domain and the high frequency behaviour of soils is considered with its conductivity and permittivity taken as functions of frequency, as the incident field has high frequency components. A soil medium can be electromagnetically viewed as a four component dielectric mixture consisting of soil particles, air voids, bound water, and free water. When electric field is incident on the soil, it gets polarized. This is as a result of a wide variety of processes, including polarization of electrons in the orbits around atoms, distortion of molecules, reorientation of water molecules, accumulation of charge at interfaces, and electrochemical reactions. Whatever is the HPEM source, an increase in the soil conductivity results in an increased attenuation of the field. Also there is a significant loss of high frequency components in the GHz range in the field due to the selective absorption by the soil. This effect causes the percentage attenuation to be maximum for HPM and minimum for NEMP and IRA lying in between these two extremities. Increase in permittivity of the soil causes attenuation of the electric field for all HPEM sources. This is due to the relaxation mechanisms in the soil due to atomic- or molecular-scale resonances. The coupling of the electromagnetic fields due to HPEM sources is considered in the first phase. Two cables are considered (i) buried shielded and (ii) buried shielded twisted pair cables. The results are arrived at using the Enhanced Transmission Line model. The induced current is more for a shielded cable than a twisted pair cable of the same configuration. The induced current magnitude depends upon the type of the HPEM source, the depth of burial of the cable and the point on the cable where the current/ voltage is computed. Current is maximum at the centre of the cable for a matched termination and the voltage is the minimum at this point. The ratio of the induced current in the inner conductor with respect to the shield current of a shielded cable is the least for an HPM, and maximum for NEMP. This is due to the fact that higher frequencies are absorbed more by the shield of the cable. This affects HPM induced current the maximum and NEMP the least because of the presence of the lower frequency components in NEMP. Induced current in the twisted pair cable depends upon the number of pairs of the cable and the pitching of the cable. The electromagnetic field from the HPEM sources propagates with less attenuation in air due to the lower resistance this medium offers for electromagnetic wave propagation. Hence any system in air, be it electrical or electronic, will be under the strong illumination by these electromagnetic fields. As the second part of this thesis, the influence of the electromagnetic fields from all the three HPEM sources on an airborne vehicle in flight is analysed. For this part of study, the Electromagnetic (EM) fields radiated by all the three sources at different heights from the earth 0s surface have been computed. The coupling study has been done for the case of a vehicle with plume as well as without plume. For the second case, the electromagnetic modelling of the plume has been done taking into consideration its conductivity, which in turn depends on the different ionic species present in the plume. The species of the exhaust plume depends upon the chemical reactions taking place in the combustion chamber of the nozzle of the vehicle. The presence of the alkali metals as impurity in the airborne vehicle propellant will generate considerable ion particles such as Na+, Cl in addition to e- in the plume mixture during combustion which makes the plume electrically conducting. But it does not influence the pressure, temperature and velocity of the plume. After the nozzle throat, the exhaust plume regains the supersonic speed, so the flow of the exhaust plume is assumed as compressible flow in the second region. The electrons have high collision frequency, high number density, high plasma frequency and lower molecular mass and hence the highly mobile electrons dominate the heavy ion particle in the computation of the electrical conductivity of the plume. The plume conductivity decreases marginally from the axis till a distance equal to the nozzle radius but the peak value increases sharply towards the exit plane edge of the nozzle radius. The induced current is computed using Method of Moments. The induced current depends upon the type of interference source, its characteristics, whether the plume is present or not and the type of the plume. The HPM induces maximum current in the vehicle because of the fact that the plume has a tendency to become more conductive at these frequencies. The induced currents due to the EM fields from IRA and NEMP comes after the HPM. The presence of the plume enhances the magnitude of the induced current. If the plume is homogeneous then the current induced in it is more.

The Irish peace process is heralded as a success among insurgencies that attempt transitions toward peaceful resolution of conflict. After thirty years of armed struggle, pitting Irish republicans against their loyalist counterparts and the British State, the North of Ireland has a reconfigured political landscape with a consociational governing body where power is shared among several parties that hold divergent political objectives. The Irish Republican Movement, whose main components are the Provisional Irish Republican Army, a covert guerilla armed organization, and Sinn Fein, the political party of Irish republicans, initiated peace that led to all-inclusive talks in the 1990s and that culminated in the signing of the Good Friday Agreement in April 1998, setting out the parameters for a non-violent way forward. Given the traditional intransigence of the IRA to consider any route other than armed conflict, how did the leadership of the Irish Republican Movement secure the support of a majority of republicans for a peace initiative that has held now for more than fifteen years? This dissertation explores the dynamics of leadership in this group, and in particular, focuses on the prisoner resistance waged by its incarcerated activists and volunteers. It is the contention here, that various prisoner resistance tactics enabled a wide-ranging group of captives to develop the skill set necessary to persuade their community to back the peace initiative, engage in electoral politics, mobilize their supporters to invest in attaining a united Ireland by peaceful negotiations, and put down their arms in a permanent and unequivocal manner. In this dissertation, the work of Paulo Freire is explored in order to capture the processes inherent the resistance-leadership continuum.
