    No full text
    This dissertation explores the construction of the pan-Africanist and socialist discourse of Kwame Nkrumah’s government—Ghana’s first independent government—during the nation-building project of the 1950s and 1960s. In 1957, when Ghana became independent, the country’s transition to self-rule emerged as a watershed moment in African and world history as this small West African country challenged an international community rooted in the political and institutional framework of the territorial nation-state with a radical program of pan-African liberation and global socialist development. By 1958, the Nkrumah government’s commitment to this radical program had resulted in supra-territorial federations with Guinea-Conakry and later Mali, while, at home, Nkrumah and his Convention People’s Party (CPP) presented the nascent nation as a model for a new form of modern, disciplined, and continental citizenship. Based on eighteen months of oral and archival research in Ghana, this dissertation reconstructs the development and performance of Nkrumah’s program of pan-African liberation and socialist development in the Ghanaian public sphere. In doing so, it interrogates the role of pan-Africanism and global socialism in shaping a vision of a growing modern, disciplined, and socialist citizenry within the Nkrumahist state. Moreover, through an examination of the press, youth, women’s, and workers’ organizations, this dissertation traces how key groups of both “elite” and “ordinary” Ghanaians embedded aspects of Nkrumahist ideology into existing idioms of power, corruption, and progress in their communities as they sought to negotiate the increasingly volatile realities associated with life in postcolonial Africa. As a result, I argue that, through the institutional framework of Nkrumah-era pan-Africanist and socialist politics, an interactive debate developed within Nkrumah’s Ghana whereby an eclectic array of Ghanaian men and women came together to debate and contest their changing places, roles, and responsibilities in the postcolonial nation. Such an analysis, I contend, provides a framework for understanding decolonization and nation-building in Africa not as the elite program of political re-organization that most scholars have portrayed it as, but as part of a dynamic set of local and transnational imaginings and contestations aimed at addressing the challenges and inequities associated with Africa’s transition to self-rule.U of I Only2 year U of I Access extension requested by author and approved by Emily Wuchner.

    27306Este trabajo analiza el impacto del proceso de integración europea sobre el volumen de exportaciones de Castilla y León durante el período 1993-2007. La metodología utilizada se basa en la estimación de una ecuación de gravedad, que constituye una herramienta útil en la modelización de los flujos de comercio bilateral. Tras aplicar un análisis de datos de panel, los resultados indican que la riqueza del país importador y de Castilla y León, así como la distancia entre ellos, son las variables básicas de la ecuación de gravedad que mejor explican el flujo exportador analizado. Respecto a los distintos acontecimientos vinculados al proceso de integración europea, nuestros hallazgos ponen de manifiesto que ni la pertenencia del país importador a la UE, ni el hecho de compartir una moneda común, han ejercido un impacto favorable significativo sobre la cifra de exportaciones de Castilla y León.S

    胡安•冈萨雷斯•德•门多萨于1585年出版的 《中华大帝国史》第一次以西班牙语和葡萄 牙语全面整理了有关中国的记述。该书正面 记录了中国明朝司法制度,并探讨了这些司 法制度与当代西班牙和墨西哥司法制度之间 的巨大差别。其中包括对法律和公共框架的 曲解,公众对证人的质疑,多层面不同形式 的惩罚,经济上的惩罚以及死刑的场景。作 者在书中强调通过奖励和惩罚双重方式对各 级官员、下属大臣进行严格控制,以保证对 各级官员的选拔任用标准,这一点也曾在蒙 田对明代官员的评价中得到过体现。此外, 胡安•冈萨雷斯•德•门多萨还十分崇敬守护印 第安人的拉斯卡萨斯,他决定从他的文献中 删掉那些为对抗中国而向强硬派提供的所谓 正当权利的论辩,如洛阿尔卡所目睹的邪恶 和杜拉埃尼亚所描述的死刑等。 González de Mendoza’s book on China, published in 1585, compiled all the first narratives about China, both Portuguese and Spanish. It contains a highly positive account of Ming criminal justice in which he emphasizes those elements of Chinese justice that deeply contrasts with Spanish and Mexican practices: the legal and public frame of torture, the public questioning of witnesses, the multilayered revisions of penalties, the public placing of the monetary fines, and the mise en scène of the death penalty. He insistently highlights the strict control upon every layer of officers and inferior ministers through a double procedure of rewards and punishments that guarantees the high standing of Chinese officials, an appraisal that Montaigne would pick up in his extremely rare allusions to China. At the same time, González de Mendoza, a thorough admirer of father Las Casas, the defender of Indians, decided to omit from his sources those elements that could provide the hardliners with arguments, the just title, to confront China, such as the nefandous sin witnessed by Loarca and the death by a thousand cuts described by Dueñas

    Does international patent collaboration have an effect on entrepreneurship?

    .Entrepreneurship is one of the main pillars of growth in any economy. Achieving a high rate of entrepreneurship in a region has become the priority objective of governments and firms. However, in many cases, new firm creation is conditioned by relations or collaboration in innovation with agents from other countries. Previous literature has analyzed the mechanisms that foster entrepreneurship. This paper attempts to shed light on the influence of international patent collaboration (IPC) on entrepreneurial activity at country level taking into account the timing of this relationship. An empirical study is proposed to verify whether IPC leads to greater entrepreneurship and to analyze the gestation period between international patenting actions and firm creation. Using the Generalized Method of Moments, the two hypotheses proposed were tested in a data panel of 30 countries for the period 2005–2017. Results show the influence of IPC in promoting entrepreneurship in the same year, but especially in the following year. The study offers implications for entrepreneurs and public agents. IPC affects the integration and interaction of international agents in a country, favors the production of new knowledge, and increases positive externalities in a territory. All this facilitates the creation of new companies with a high innovative component.S

    A new index of resilience applicable to external pulse-disturbances that considers the recovery of communities in the short term

    Get PDF
    .Resilience is a key concept in the study of the recovery of ecosystems affected by disturbances. Currently, there are numerous indices to measure resilience, but many of them do not show the accuracy of the resilience value or the behaviour of ecological parameters in the face of disturbances. New approaches and technologies enable large amounts of information to be obtained, facilitating the proposal of new resilience indices that work consistently and intuitively for a wide variety of ecological response variables under different scenarios after pulse-disturbances. In this study, we propose and verify a new resilience index, comparing its performance with others previously published. We validated the performance of the new index using real data based on field measurements of changes in soil bacterial OTUs diversity and abundance after a wildfire. The new resilience index provided an automatic and robust functional classification of the behaviour of ecosystems after disturbances, supported by a bootstrap analysis. We identified 5 scenarios of ecosystem resilience performance according to their behaviour after a pulse-disturbance: resilient, non-resilient, recovering, rebound, and continuing.S

    Identification of Hindbrain Neural Substrates for Motor Initiation in the hatchling Xenopus laevis Tadpole

    Animal survival profoundly depends on the ability to detect stimuli in the environment, process them and respond accordingly. In this respect, motor responses to a sensory stimulation evolved into a variety of coordinated movements, which involve the control of brain centres over spinal locomotor circuits. The hatchling Xenopus tadpole, even in its embryonic stage, is able to detect external sensory information and to swim away if the stimulus is considered noxious. To do so, the tadpole relies on well-known ascending sensory pathway, which carries the sensory information to the brain. When the stimulus is strong enough, descending interneurons are activated, leading to the excitation of spinal CPG neurons, which causes the undulatory movement of swimming. However, the activation of descending interneurons that marks the initiation of motor response appears after a long delay from the sensory stimulation. Furthermore, the long-latency response is variable in time, as observed in the slow-summating excitation measured in descending interneurons. These two features, i.e. long-latency and variability, cannot be explained by the firing time and pattern of the ascending sensory pathway of the Xenopus tadpole. Therefore, a novel neuronal population has been proposed to lie in the hindbrain of the tadpole, and being able to 'hold' the sensory information, thus accounting for the long and variable delay of swim initiation. In this work, the role of the hindbrain in the maintenance of the long and variable response to trunk skin stimulation is investigated in the Xenopustadpole at developmental stage 37/38. A multifaceted approach has been used to unravel the neuronal mechanisms underlying the delayed motor response, including behavioural experiments, electrophysiology analysis of fictive swimming, hindbrain extracellular recordings and imaging experiments. Two novel neuronal populations have been identified in the tadpole's hindbrain, which exhibit activation patterns compatible with the role of delaying the excitation of the spinal locomotor circuit. Future work on cellular properties and synaptic connections of these newly discovered populations might shed light on the mechanism of descending control active at embryonic stage. Identifying supraspinal neuronal populations in an embryonic organism could aid in understanding mechanisms of descending motor control in more complex vertebrates

    Interactive Sonic Environments: Sonic artwork via gameplay experience

    The purpose of this study is to investigate the use of video-game technology in the design and implementation of interactive sonic centric artworks, the purpose of which is to create and contribute to the discourse and understanding of its effectiveness in electro-acoustic composition highlighting the creative process. Key research questions include: How can the language of electro-acoustic music be placed in a new framework derived from videogame aesthetics and technology? What new creative processes need to be considered when using this medium? Moreover, what aspects of 'play' should be considered when designing the systems? The findings of this study assert that composers and sonic art practitioners need little or no coding knowledge to create exciting applications and the myriad of options available to the composer when using video-game technology is limited only by imagination. Through a cyclic process of planning, building, testing and playing these applications the project revealed advantages and unique sonic opportunities in comparison to other sonic art installations. A portfolio of selected original compositions, both fixed and open are presented by the author to complement this study. The commentary serves to place the work in context with other practitioners in the field and to provide compositional approaches that have been taken

    Balancing the urban stomach: public health, food selling and consumption in London, c. 1558-1640

    Get PDF
    Until recently, public health histories have been predominantly shaped by medical and scientific perspectives, to the neglect of their wider social, economic and political contexts. These medically-minded studies have tended to present broad, sweeping narratives of health policy's explicit successes or failures, often focusing on extraordinary periods of epidemic disease viewed from a national context. This approach is problematic, particularly in studies of public health practice prior to 1800. Before the rise of modern scientific medicine, public health policies were more often influenced by shared social, cultural, economic and religious values which favoured maintaining hierarchy, stability and concern for 'the common good'. These values have frequently been overlooked by modern researchers. This has yielded pessimistic assessments of contemporary sanitation, implying that local authorities did not care about or prioritise the health of populations. Overly medicalised perspectives have further restricted historians' investigation and use of source material, their interpretation of multifaceted and sometimes contested cultural practices such as fasting, and their examination of habitual - and not just extraordinary - health actions. These perspectives have encouraged a focus on reactive - rather than preventative - measures. This thesis contributes to a growing body of research that expands our restrictive understandings of pre-modern public health. It focuses on how public health practices were regulated, monitored and expanded in later Tudor and early Stuart London, with a particular focus on consumption and food-selling. Acknowledging the fundamental public health value of maintaining urban foodways, it investigates how contemporaries sought to manage consumption, food production waste, and vending practices in the early modern City's wards and parishes. It delineates the practical and political distinctions between food and medicine, broadly investigates the activities, reputations of and correlations between London's guild and itinerant food vendors and licensed and irregular medical practitioners, traces the directions in which different kinds of public health policy filtered up or down, and explores how policies were enacted at a national and local level. Finally, it compares and contrasts habitual and extraordinary public health regulations, with a particular focus on how perceptions of and actual food shortages, paired with the omnipresent threat of disease, impacted broader aspects of civic life

    Paradoxes in the Management of Timebanks in the UK’s Voluntary Sector: Discursive Bricolage and its Limits

    Get PDF
    This paper contributes to our understanding of volunteer management by charting some important challenges associated with the governance of one of the UK’s largest timebanking networks. While timebanking is often treated as a form of volunteering, many timebank advocates are keen to distinguish it sharply from traditional volunteering. We suggest that this tension generates a fundamental ‘performance paradox’ in the management of timebanks in the voluntary sector. We draw on political discourse theory to characterise and evaluate associated challenges, suggesting that, when viewed against a host of context-specific organisational and policy pressures, the progressive potential of timebanking cannot be realised as a distinct community economy without adequate support. Instead of taking up a position alongside more traditional forms of volunteering, timebanking is more likely to be subsumed by them
