Warfare in the West Highlands and Isles of Scotland, c. 1544-1615

Warfare has long been associated with Scottish Highlanders and Islanders, especially in the period known in Gaelic tradition as ‘Linn nan Creach’ (the ‘Age of Forays’), which followed the forfeiture of the Lordship of the Isles in 1493. The sixteenth century in general is remembered as a particularly tumultuous time within the West Highlands and Isles, characterised by armed conflict on a seemingly unprecedented scale. Relatively little research has been conducted into the nature of warfare however, a gap filled by this thesis through its focus on a series of interconnected themes and in-depth case studies spanning the period c. 1544-1615. It challenges the idea that the sixteenth century and early seventeenth century was a time of endless bloodshed, and explores the rationale behind the distinctive mode of warfare practised in the West Highlands and Isles. The first part of the thesis traces the overall ‘Process of War’. Chapter 1 focuses on the mentality of the social elite in the West Highlands and Isles and demonstrates that warfare was not their raison d'être, but was tied inextricably to chiefs’ prime responsibility of protecting their lands and tenants. Chapter 2 assesses the causation of warfare and reveals that a recurrent catalyst for armed conflict was the assertion of rights to land and inheritance. There were other important causes however, including clan expectation, honour culture, punitive government policies, and the use of proxy warfare by prominent magnates. Chapter 3 takes a fresh approach to the military capacity of the region through analysis of armies and soldiers, and the final thematic chapter tackles the conduct of warfare in the West Highlands and Isles, with analysis of the tactics and strategy of militarised personnel. The second part of this thesis comprises five case studies: the Clanranald, 1544-77; the Colquhouns of Luss and the Lennox, 1592-1603; the MacLeods of Harris and MacDonalds of Sleat, 1594-1601; the Camerons, 1569-1614; and the ‘Islay Rising’, 1614-15. This thesis adopts a unique approach by contextualising the political background of warfare in order to instil a deeper understanding of why early modern Gaelic Scots resorted to bloodshed. Overall, this period was defined by a sharp rise in military activity, followed by an even sharper decline, a trajectory that will be evidenced vividly in the final case study on the ‘Islay Rising’. Although warfare was widespread, it was not unrestrained or continuous, and the traditional image of a region riven by perpetual bloodshed has been greatly exaggerated.

Original sin: divine and symbolic violence in the turn to the Apostle Paul

When we take a step back from the imposing figure of physical violence, it becomes possible to examine other structurally violent forces that constantly shape our cultural and political landscapes. One of the driving interests in the “turn to Paul” in recent continental philosophy stems from wrestling with questions about the real nature of contemporary violence. Paul is positioned as a thinker whose messianic experience began to cut through the violent masquerade of the existing order. The crucifixion and resurrection of the Messiah (a slave and a God co-existing in one body) exposed the empty grounding upon which power resided. The Christ-event signifies a moment of violent interruption in the existing order which Paul enjoins the Gentiles to participate in through a dedication of love for the neighbour. This divine violence aims to reveal and subvert the “powers,” epitomised in the Roman Empire, in order to fulfil the labour of the Messianic now-time which had arrived. The impetus behind this research comes from a typically enigmatic and provocative section of text by the Slovene philosopher, cultural critic, and Christian atheist Slavoj Žižek. He claims that 'the notion of love should be given here all its Paulinian weight: the domain of pure violence… is the domain of love' (2008a, 173). In this move he links Paul’s idea of love to that of Walter Benjamin’s divine violence; the sublime and the cataclysmic come together in this seemingly perverse notion. At stake here is the way in which uncovering violent forces in the “zero-level” of our narrative worldviews aids the diagnosis of contemporary political and ethical issues. It is not enough to imagine Paul’s encounter with the Christ-event as non-violent. This Jewish apocalyptic movement was engaged in a violent struggle within an existing order that God’s wrath will soon dismantle. Paul’s weak violence, inspired by his fidelity to the Christ-event, places all responsibility over creation in the role of the individual within the collective body. The centre piece of this re-imagined construction of the Pauline narrative comes in Romans 13: the violent dedication to love understood in the radical nature of the now-time. 3 This research examines the role that narratives play in the creation and diagnosis of these violent forces. In order to construct a new genealogy of violence in Christianity it is crucial to understand the role of the slave of Christ (the revolutionary messianic subject). This turn in the Symbolic is examined through creating a literary structure in which we can approach a radical Nietzschean shift in Pauline thought. The claim here, a claim which is also central to Paul’s letters, is that when the symbolic violence which manipulates our worldviews is undone by a divine violence, if even for a moment, new possibilities are created in the opening for a transvaluation of values. Through this we uncover the nature of original sin: the consequences of the interconnected reality of our actions. The role of literature is vital in the construction of this narrative; starting with Cormac McCarthy’s No Country for Old Men, and continuing through works such as Melville’s Bartleby the Scrivener, this thesis draws upon the power of literature in the shaping of our narrative worlds. Typical of the continental philosophy at the heart of this work, a diverse range of illustrations and inspirations from fiction is pulled into its narrative to reflect the symbolic universe that this work was forged through. What this work attempts to do is give this theory a greater grounding in Paul’s letters by demonstrating this radical kenotic power at the heart of the Christ-event. Romans 13 reveals, in a way that has not yet been picked up by Critchley, Žižek, and others, that Paul opposed the biopolitical power of the Roman Empire through the weak violence of love that is the labour of the slaves of Christ on the “now-time” that had arrived.

Estudo empírico de antecedentes do sucesso de sistemas de informação: análise de um sistema de apoio à decisão em uma universidade pública

Universities are institutions that generate and manipulate large amounts of data as a result of the multiple functions they perform, of the amount of involved professionals and students they attend. Information gathered from these data is used, for example, for operational activities and to support decision-making by managers. To assist managers in accomplishing their tasks, the Information Systems (IS) are presented as tools that offer features aiming to improve the performance of its users, assist with routine tasks and provide support to decision-making. The purpose of this research is to evaluate the influence of the users features and of the task in the success of IS. The study is of a descriptive-exploratory nature, therefore, the constructs used to define the conceptual model of the research are known and previously validated. However, individual features of users and of the task are IS success antecedents. In order to test the influence of these antecedents, it was developed a decision support IS that uses the Multicriteria Decision Aid Constructivist (MCDA-C) methodology with the participation and involvement of users. The sample consisted of managers and former managers of UTFPR Campus Pato Branco who work or have worked in teaching activities, research, extension and management. For data collection an experiment was conducted in the computer lab of the Campus Pato Branco in order to verify the hypotheses of the research. The experiment consisted of performing a distribution task of teaching positions between the academic departments using the IS developed. The task involved decision-making related to management activities. The data that fed the system used were real, from the Campus itself. A questionnaire was answered by the participants of the experiment in order to obtain data to verify the research hypotheses. The results obtained from the data analysis partially confirmed the influence of the individual features in IS success and fully confirmed the influence of task features. The data collected failed to support significant ratio between the individual features and the individual impact. For many of the participants the first contact with the IS was during the experiment, which indicates the lack of experience with the system. Regarding the success of IS, the data revealed that there is no significance in the relationship between Information Quality (IQ) and Individual Impact (II). It is noteworthy that the IS used in the experiment is to support decision-making and the information provided by this system are strictly quantitative, which may have caused some conflict in the analysis of the criteria involved in the decision-making process. This is because the criteria of teaching, research, extension and management are interconnected such that one reflects on another. Thus, the opinion of the managers does not depend exclusively on quantitative data, but also of knowledge and value judgment that each manager has about the problem to be solved.

Single-molecule fluorescence resonance energy transfer study of SNARE-mediated membrane fusion

This is a comprehensive study of protein-mediated membrane fusion through single-molecule fluorescence resonance energy transfer (smFRET). Membrane fusion is one of the important cellular processes by which two initially distinct lipid bilayers merge their hydrophobic cores, resulting in one interconnected structure. For example, exocytosis, fertilization of an egg by a sperm and communication between neurons are a few among many processes that rely on some form of fusion. Proteins called soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) play a central role in fusion processes which is also regulated by many accessory proteins, such as synaptotagmin, complexin and Munc18. By a new lipid mixing method at the single-vesicle level, we are able to accurately detect different stages of SNARE-mediated membrane fusion including docking, hemi and full fusion via FRET value of single donor/acceptor vesicle pair. Through this single-vesicle lipid mixing assay, we discovered the vesicle aggregation induced by C2AB/Ca2+, the dual function of complexin, and the fusion promotion role of Munc18/SNARE-core binding mode. While this new method provides the information regarding the extent of the ensemble lipid mixing, the fusion pore opening between two vesicular cavities and the interaction between proteins cannot be detected. In order to overcome these limitations, we then developed a single-vesicle content mixing method to reveal the key factor of pore expansion by detecting the FRET change of dual-labeled DNA probes encapsulated in vesicles. Through our single-vesicle content mixing assay, we found the fusion pore expansion role of yeast SNAREs as well as neuronal SNAREs plus synaptotagmin 1.

Controle de uma microrrede ilhada baseada em geração eólica-diesel com alto nível de inserção de geração eólica

The insertion of distributed generation units in the electric power systems have contributed to the popularization of microgrid concepts. With the microgrids, several potential benefits can be achieved in regard to power quality and supply reliability. However, several technical challenges related to the control and operation of microgrids, which are associated with high insertion of generation systems based on static converters, must be overcame. Among the opportunities in the context of microgrids, there is the islanded operation of microgrids temporarily disconnected from the electric power systems and also the autonomous operation of geographically isolated microgrids. The frequency in large power systems is traditionally controlled by the generation units based on traditional synchronous generator. The insertion of distributed generation units based on static power converters may bring difficulties to the frequency control in microgrids, due to the reduction of the equivalent inertia of conventional synchronous generators present in islanded and isolated microgrids. In this context, it becomes necessary the proposition of new operational and control strategies for microgrids control, taking into account the presence of distributed generation units based on full-rated converter. This paper proposes an operational and control strategy for the islanded operation of a winddiesel microgrid with high insertion level of wind generation. The microgrid adopted in this study comprises of a wind energy conversion system with synchronous generator based on full rated converter, a diesel generator (DIG) and a dump load. Due to the high insertion level of wind generation, the wind unit operates in Vf mode and the diesel generator operates in PQ mode. The diesel generator and the dump load are used to regulate the DC-link voltage of the wind generation unit. The proposed control allows the islanded operation of the microgrid only with wind generation, wind-only mode (WO), and with wind-diesel generation, wind-diesel mode (WD). For the wind-only mode, with 100% of penetration level of wind generation, it is proposed a DC-link voltage control loop based on the use of a DC dump load. For the winddiesel mode, it is proposed a DC-link voltage control loop added to the diesel generator, which is connected to the AC side of the microgrid, in coordinated action with the dump load. The proposed operational and control strategy does not require the use of batteries and aims to maximize the energy production from wind generation, ensuring the uninterrupted operation of the microgrid. The results have showed that the operational and control strategy allowed the stable operation of the islanded microgrid and that the DC-link voltage control loop added to the diesel generator and the dump load proved to be effective during the typical variations of wind speed and load.

Adaptability, Transformation and Complex Changes in Namibia and Tanzania: Resilience and Innovation System Development in Local Communities

This thesis is a research about the recent complex spatial changes in Namibia and Tanzania and local communities’ capacity to cope with, adapt to and transform the unpredictability engaged to these processes. I scrutinise the concept of resilience and its potential application to explaining the development of local communities in Southern Africa when facing various social, economic and environmental changes. My research is based on three distinct but overlapping research questions: what are the main spatial changes and their impact on the study areas in Namibia and Tanzania? What are the adaptation, transformation and resilience processes of the studied local communities in Namibia and Tanzania? How are innovation systems developed, and what is their impact on the resilience of the studied local communities in Namibia and Tanzania? I use four ethnographic case studies concerning environmental change, global tourism and innovation system development in Namibia and Tanzania, as well as mixed-methodological approaches, to study these issues. The results of my empirical investigation demonstrate that the spatial changes in the localities within Namibia and Tanzania are unique, loose assemblages, a result of the complex, multisided, relational and evolutional development of human and non-human elements that do not necessarily have linear causalities. Several changes co-exist and are interconnected though uncertain and unstructured and, together with the multiple stressors related to poverty, have made communities more vulnerable to different changes. The communities’ adaptation and transformation measures have been mostly reactive, based on contingency and post hoc learning. Despite various anticipation techniques, coping measures, adaptive learning and self-organisation processes occurring in the localities, the local communities are constrained by their uneven power relationships within the larger assemblages. Thus, communities’ own opportunities to increase their resilience are limited without changing the relations in these multiform entities. Therefore, larger cooperation models are needed, like an innovation system, based on the interactions of different actors to foster cooperation, which require collaboration among and input from a diverse set of stakeholders to combine different sources of knowledge, innovation and learning. Accordingly, both Namibia and Tanzania are developing an innovation system as their key policy to foster transformation towards knowledge-based societies. Finally, the development of an innovation system needs novel bottom-up approaches to increase the resilience of local communities and embed it into local communities. Therefore, innovation policies in Namibia have emphasised the role of indigenous knowledge, and Tanzania has established the Living Lab network.

Minas e memórias da Urgeiriça: contributos da arte para a sensibilização ambiental

O projeto "Minas e Memórias da Urgeiriça" focaliza-se nos contributos da arte enquanto vetor de sensibilização ambiental, entendida como um veículo privilegiado para promover comportamentos e atitudes mais sustentáveis, responsáveis e cívicas, apelando para a mudança ou para o reforço de boas práticas ambientais. O projeto foi implementado no Concelho de Nelas, distrito de Viseu, baseando-se na história socioambiental das Minas da Urgeiriça, localizadas na freguesia de Canas de Senhorim. Abarcou um conjunto de atividades de índoles pedagógico e artístico, que se interligaram coerentemente, iniciando-se com o seminário “Urgeiriça: Antes, Agora e Depois?”, seguindo-se a performance “Escuridão” complementada pelos cantares de hinos dos ex-trabalhadores das Minas da Urgeiriça, culminando na visita à instalação artística “Escavações”. Os resultados estão ancorados em duas premissas fundamentais: por um lado, os testemunhos reais dos ex-trabalhadores mineiros expressaram a influência da ação do homem sobre a natureza de forma descomedida e irresponsável, que continua a acarretar consequências nefastas para o ser humano, e por outro, demonstraram as intervenções a que o local se sujeitou (da exploração desenfreada de recursos até à progressiva requalificação). Para tal, conseguiu-se revitalizar e reforçar as memórias do espaço (físico e mental) e materializá-las através da arte como forma de sensibilizar a comunidade local acerca das ações resultantes da interação do homem versus ambiente, sendo encaradas como meio privilegiado de desenvolvimento comunitário, gerador de competências e de mudanças.

A cyber exercise post assessment framework: In Malaysia perspectives

Critical infrastructures are based on complex systems that provide vital services to the nation. The complexities of the interconnected networks, each managed by individual organisations, if not properly secured, could offer vulnerabilities that threaten other organisations’ systems that depend on their services. This thesis argues that the awareness of interdependencies among critical sectors needs to be increased. Managing and securing critical infrastructure is not isolated responsibility of a government or an individual organisation. There is a need for a strong collaboration among critical service providers of public and private organisations in protecting critical information infrastructure. Cyber exercises have been incorporated in national cyber security strategies as part of critical information infrastructure protection. However, organising a cyber exercise involved multi sectors is challenging due to the diversity of participants’ background, working environments and incidents response policies. How well the lessons learned from the cyber exercise and how it can be transferred to the participating organisations is still a looming question. In order to understand the implications of cyber exercises on what participants have learnt and how it benefits participants’ organisation, a Cyber Exercise Post Assessment (CEPA) framework was proposed in this research. The CEPA framework consists of two parts. The first part aims to investigate the lessons learnt by participants from a cyber exercise using the four levels of the Kirkpatrick Training Model to identify their perceptions on reaction, learning, behaviour and results of the exercise. The second part investigates the Organisation Cyber Resilience (OCR) of participating sectors. The framework was used to study the impact of the cyber exercise called X Maya in Malaysia. Data collected through interviews with X Maya 5 participants were coded and categorised based on four levels according to the Kirkpatrick Training Model, while online surveys distributed to ten Critical National Information Infrastructure (CNII) sectors participated in the exercise. The survey used the C-Suite Executive Checklist developed by World Economic Forum in 2012. To ensure the suitability of the tool used to investigate the OCR, a reliability test conducted on the survey items showed high internal consistency results. Finally, individual OCR scores were used to develop the OCR Maturity Model to provide the organisation cyber resilience perspectives of the ten CNII sectors.

The Ballad of Ravolo Soto

Set in 2008 Puerto Rico, this novel aims to explore the relationship between constructed masks of personal identity, the increasingly interconnected nature of community, and their confluence in the worlds of politics, media, social activism, and business through a narrative examination of the ways in which three primary characters affect the lives of those around them. Jaime, a meditative young man with a penchant for planes, comes home to find the power shut off and his drug-addict mother gone. His best friend, Yarique, a disaffected stoner with a false sense of machismo, becomes an overnight sensation after an escalating series of violent run-ins with his abuelo’s neighbor. Ravolo Soto, a reclusive pitorro distiller, drinks to keep The Other in check, but takes off into the jungles of Lares, hiding out in his father’s mountain shack, after a violent encounter with the police leaves one officer dead.

Proposta de uma matriz de decisão em energia hidrelétrica com o uso do método multicritério, para formulação de políticas públicas no estado do Paraná

Brazil is internationally acknowledged for its renewable sources, most notably, hydroelectric power plant projects which correspond to 65% of electricity production supply to the National Interconnected System. The main question behind this research is: what are the weights and the relative importance of the variables which have influence on the decision making process for the expansion of hydroelectric generation projects in Parana? The main objective is to propose a multi-criteria decision procedure, in association with water sources options that take into consideration the weight and relative importance of the alternatives having influence on the decision by enterprises in the generation of electricity in the state of Paraná. As far as the approach to the problem is concerned, this research can be classified as having mixed methodologies, applying Content Analysis, Delphi technique and the Analytic Hierarchy Process. Following Delphi methodology, a group of 21 was selected for data collection, all of those linked to Paranaense hydroelectricity market. And the main result was the construction of a decision tree in which it was possible to identify the importance and relative weight of the elements associated with the four dimensions of energy. In environmental dimension, the highest relative weight was placed on the loading capacity of Parana system; the economic dimension, the amortization of investment; in social dimension, the generation of direct work places and in institutional dimension, the availability of suitable sources of financing. Policy makers and business managers make their decisions based on specific criteria related to the organization segment, market information, economic and political behavior among other indicators that guide them in dealing with the typical tradeoffs of projects in hydropower area. The results obtained in the decision tree show that the economic bias is still the main factor in making investment decisions. However, environmental impacts on the State loading capacity, income generation, providing opportunities for direct as well as indirect jobs. And at an institutional level, the absence of funding sources show that the perception of experts is focused on other issues beyond the logic behind development per se. The order of priority of variables in this study indicates that in the current environment of uncertainty in the Brazilian economy as many variables must be analyzed and compared in order to optimize the scarce resources available to expand local development in relation to Paranaense water matrix.

Aprendizagem histórica: diálogos entre a telenovela “Gabriela” e a historiografia

Iniciamos esta pesquisa a partir da compreensão que a aprendizagem dos saberes históricos se realiza de diferentes formas, na maioria das vezes para além das salas de aulas, e, está diretamente relacionada às instâncias em que se processa. Estas instâncias são a acadêmica e a de circulação massiva, as quais possuem caracteres distintos. Aprendizagem histórica, portanto, ocorre mediante três fatores: o primeiro diz respeito à consciência histórica surgida no cotidiano, na práxis da vida, regida pela cultura do individuo; o segundo relaciona-se a historiografia, ou seja, o modo como as informações dos eventos históricos inscritos na mente dos homens é transformada em história oficial, o que envolve métodos de pesquisa, referenciais teóricos, argumentação e narrativa; o terceiro fator é próprio sistema escolar e a forma com que se ensina história. Assim, o aprendizado histórico, emerge na narrativa histórica, quando as operações mentais da experiência, da interpretação e da orientação são realizadas, situação em que a história é apontada como responsável pela orientação cultural na vida prática dos sujeitos. Deste modo, objetivamos nesta pesquisa analisar as relações dialéticas entre uma cultura histórica construída através da historiografia sobre os conceitos de coronelismo e clientelismo e a narrativa desses conceitos na telenovela Gabriela e essa como meio de massificação da aprendizagem Histórica. Para isso, adotamos o método do estudo de casos múltiplos, o qual foi suportado nas técnicas de entrevista e da análise de conteúdo. Obtivemos duas categorias de aprendizagem histórica nas narrativas dos participantes: 1) Coronelismo/ clientelismo e 2) Sociedade. Concluímos que as cenas apresentadas em Gabriela em sua maioria convergiram para os apontamentos da historiografia, portanto qualificando-a como uma narrativa histórica. Esta narrativa foi decodificada pelos telespectadores em conformidade com sua própria cultura e permitiu a construção de saberes que se apresentaram interligados nas falas dos participantes. As operações mentais da experiência, interpretação e orientação foram processadas de forma distinta entre os sujeitos do grupo amostral, fator que evidenciou a individualidade do aprendizado de cada participante. Dessa forma, o contato com esta representação televisiva do passado, possibilitou-lhes aquisição do conteúdo histórico, o qual foi ressignificado de modo a possibilitar a compreensão do presente e a criar expectativas de futuro, definindo a ação dos participantes em sua práxis cotidiana.

Magnetic carbon xerogels for the catalytic wet peroxide oxidation of sulfamethoxazole in environmentally relevant water matrices

Novel magnetic carbon xerogels consisting of interconnected carbon microspheres with iron and/or cobalt microparticles embedded in their structure were developed by a simple route. As inferred from the characterization data, materials with distinctive properties may be directly obtained upon inclusion of iron and/or cobalt precursors during the sol-gel polymerization of resorcinol and formaldehyde, followed by thermal annealing. The unique properties of these magnetic carbon xerogels were explored in the catalytic wet peroxide oxidation (CWPO) of an antimicrobial agent typically found throughout the urban water cycle – sulfamethoxazole (SMX). A clear synergistic effect arises from the inclusion of cobalt and iron in carbon xerogels (CX/CoFe),the resulting magnetic material revealing a better performance in the CWPO of SMX at the ppb level(500 microg L−1) when compared to that of monometallic carbon xerogels containing only iron or cobalt.This effect was ascribed to the increased accessibility of highly active iron species promoted by the simultaneous incorporation of cobalt.The performance of the CWPO process in the presence of CX/CoFe was also evaluated in environmentally relevant water matrices, namely in drinking water and secondary treated wastewater, considered in addition to ultrapure water. It was found that the performance decreases when applied to more complex water and wastewater samples. Nevertheless, the ability of the CWPO technology for the elimination of SMX in secondary treated wastewater was unequivocally shown, with 96.8% of its initial content being removed after 6 h of reaction in the presence of CX/CoFe, at atmospheric pressure, room temperature(T = 25◦C), pH = 3, [H2O2]0= 500 mg L−1and catalyst load = 80 mg L−1. A similar performance (97.8% SMX removal) is obtained in 30 min when the reaction temperature is slightly increased up to 60◦C in an ultra-pure water matrix. Synthetic water containing humic acid, bicarbonate, sulphate or chloride, was also tested. The results suggest the scavenging effect of the different anions considered, as well as the negative impact of dissolved organic matter typically found in secondary treated wastewater, as simulated by the presence of humic acid.An in-situ magnetic separation procedure was applied for catalyst recovery and re-use during reusability cycles performed to mimic real-scale applications. CWPO runs performed with increased SMX concentration (10 mg L−1), under a water treatment process intensification approach, allowed to evalu-ate the mineralization levels obtained, the antimicrobial activity of the treated water, and to propose adegradation mechanism for the CWPO of SMX.

Towards a Research Proposal Outline of the Central Library

Few studies relating to librarianship as a science, because it is argued that the Library lacks a body of theory, an object of study and methodology of its own. According to Murcia and Tamayo "science is a critical task not dogmatic, that puts all its cases to trial and criticism." 0 is, science tests the presumed knowledge. He adds that science related facts and interconnected with each other, in order to achieve logical connections that allow the provision of postulates and axioms from the systematization achieved through research and the scientific method to determine the objectivity that exists between facts and phenomena. For him, scientific research is the instrument by which science makes it to scientific knowledge. (1982, p. 11)
