Abstract:
Sherry Ortner's account of the development of anthropological theory is admirable both because of the complexity of her argument and because it opens up a series of interesting possibilities for theoretical self-criticism among anthropologists. In this essay, I consider a theme which is not directly addressed in Ortner's piece, but which might usefully be considered in relation to it. The theme involves the significance of place in the construction of anthropological theory in the period since World War II.

Abstract:
Abstract This paper situates center-periphery issues at two levels. At the broadest level (world system), it looks at the spectrum of selected dependency theories and the position of George Klay Kieh Jr’s ideas in this spectrum. In this discussion, I will pay especial attention to small states, powers and economies and explain the justifications in the section below. At the intermediate level (compradorial category) of the world system, I examined some area-specific writings on this subject, in particular those related to Asia and Africa but also classical studies of compradorial economies in South America. In reviewing these theories, I identified three major issues for study. First, are dependency theories and the idea of an intermediate compradorial economy in the world system still relevant or important to the study of developing economies? Second, are regional economic bodies in the intermediate space of the world system challenging the dichotomous binary of only center and periphery? Third, if resource supply and primary processing are the comparative advantages of smaller or peripheral states, can regional cooperation help to upgrade the value-added-ness of their economic activities?

Abstract:
Contemporary conflict research usually measures the influence of ethnicity on conflict by capturing ethnic constellations as country-based indices, such as ethnic fractionalization or polarization. However, such aggregated measures are likely to conceal the actual operation of actor-specific mechanisms. In this article, therefore, we introduce a disaggregated model that measures ethnic groups' access to power. We do so by disaggregating both ethnicity and conflict to the level of explicitly geo-coded center-periphery dyads. This procedure allows us to measure the power balance between politically excluded ethnic groups and dominant actors in terms of group sizes, distances between the center and the periphery, and the roughness of the latter's terrain. We rely on geographic information systems (GIS) to compute demographic and ethno-geographic variables. The dyadic analysis enables us to show that exclusion of powerful ethnic minorities increases the likelihood of conflict considerably. In addition, we show that the risk of conflict is positively associated with the extent of rough terrain in the peripheral group's home region and its distance from the political center.

Abstract:
The aim of this study is to describe the role of the state in Turkish modernization. For this purpose, Ottoman-Turkish political history is discussed in the context of the "center-periphery" model and Metin Heper's "strong state tradition". In this context, it is discussed whether the general validity of the center-periphery model continues. The center-periphery theory, which reduces modernization to tension and conflict between the superstructure institutions in Turkey, has made the opposition between the urban-secular-middle classes and the traditional-poor-lower classes its starting point. According to the strong state tradition thesis, the ruling elites, who took the modern values transferred from the West as a reference, were insensitive to the environment while constantly strengthening the center. The authoritarian structure of the state prevented the development of different social classes and non-governmental organizations. The strong state tradition transferred from the Ottoman Empire continued to be effective in the republic period as the subject of modernization. So much so that the bureaucratic structure that established the Republic identified itself with the state and strengthened the center until the multi-party system. Cultural conflict and tension between the ruling elites representing the center and traditional society segments representing the periphery have also been decisive in terms of the power struggle. The rise of the neo-liberal wave in the 1980s had reflections on the power struggle in Turkey and affected the relations between the center and the periphery. While the old elites forming the center became the periphery, the conservative sections forming the periphery became centralized and formed the new elites. In conclusion, it can be said that the center-periphery theory and strong state tradition are still functional in explaining Ottoman-Turkish modernization with some reservations. Key Words: Ruling elites, Center-Periphery Model, strong state tradition.

Abstract:
This paper expands the framework of the Bourdieusian field theory using a world-system theoretical perspective to analyze the global system of social sciences, or what might be called the world-system of knowledge production. The analysis deals with the main agents of the world-system of social sciences, and it also investigates the core-like and periphery-like processes of the system. Our findings affirm that a very characteristic center-periphery structure exists in global social sciences, with a few hegemonic countries and distinctly peripheral world regions. Our analysis not just presents empirical data on power structures in global social sciences but it also offers meaningful typologies for analysis of the roles different world regions play in maintaining the world-system of global knowledge production. The paper also proposes a three-dimensional model by which both geographical and social/institutional center-periphery relations may be analyzed.

Abstract:
This article presents an overview of the paths of sociology in times of change in a globalized world. Looking at the four-year period from the XVIII ISA World Congress of Sociology, in Yokohama, to the XIX ISA World Congress of Sociology, in Toronto, it is possible to argue that sociology is going global and growing stronger each day. The paper stresses the importance of comparative analysis, the integration of theory and method, and the defense of Sociology as a scientific and academic field. The major question is how to keep on the move during times of profound geopolitical and geo-economic transformations and what is the place of Sociology in the global era. Hereupon we address the debate about sociological research in the 21st century considering the challenges and possibilities open to our academic field. We also analyze the contribution to sociological analysis of Latin-American and the BRICS sociologies who bring in perspectives that can go beyond the theories developed by early industrialized countries or, as they are called here, central countries.

Abstract:
The article attempts to outline new approaches to the study of the timber industry complex as one of the main instruments of interaction between the State and Karelia, as the Finno-Ugric region, during the second half of the 20th century. The aim of the study is to find the theories and concepts that could form the basis for the systematic analysis of the interaction. The urgency of the study is related to the fact that for many forest-producing regions of Russia, including Karelia, the result of the regional state social and economic policy during the studied period turned out to be largely negative. The research methodology is based on the use of modernization theory and the concept “center – periphery”. The article is based on the research of international and Russian scholars which interpret these concepts. The comparison of theoretical material with the historical experience of development of Karelia in the second half of the 20th century allows to draw a conclusion about the possibility of successful combination of the noted research approaches. Various interpretations of the theory of modernization made it possible draw a conclusion about the peripheral nature of the modernization processes in this region in relation to socio-economic development of Karelia. Using the concept “center – periphery”, according to which the unevenness of economic growth and the process of spatial polarization inevitably generate disparities between the so-called center and periphery, has shown its potential in the study of the peculiarities of interaction between the state and the Finno-Ugric region. Comparison of these two concepts makes it possible to draw a conclusion about the high degree of their mutual complementarity and the possibility in the long term to propose the realization of a center-peripheral model of regional modernization in the social and economic development of Karelia.

Abstract:
Introduction. The study is of relevance due to the need to expand the theoretical developments in the field of spatial economics within the regional system in order to form adequate and flexible measures to stimulate and support the subjects of the intraregional environment. With regard to the state authorities’ growing interest in the tendencies of spatial development of territories, a careful analysis of the full diversity of processes and connections that take place within individual regions is necessary. The purpose of the study is to identify and analyze these processes. Materials and Methods. The information and empirical base of the study included statistical data presented on the official website of the regional Department of Statistics in the Stavropol Territory and its municipal units. Fundamental methods of scientific knowledge were employed, the gravitational model was applied, and the tools of correlation and regression analysis were used to test hypotheses and calculated conclusions. Results. For the first time, analytical data were obtained on the level, strength and direction of the spatial gravitation between the center and the peripheral territories in an agro-industrial region – the Stavropol Territory. The gravitational model adapted for studying the spatial processes of interaction of the ‘center–periphery’ system was for the first time tested in the conditions of an agro-industrial region. On the basis of the theory of gravitational environments, conclusions were drawn about the presence of specific processes in the region in the form of establishment of ‘the second-order’ gravitation centers, which are ‘beacons’ for the periphery due to a higher level of socio-economic development and general territorial remoteness from the main regional center. Discussion and Conclusion. The implementation of the presented diagnostic approach made it possible to put forward a number of hypotheses about the presence and specificity of the spatial connections between the objects of the regional ‘center–periphery’ system. The force of gravitation, the direction and type of the spatial drift can have a direct impact on the level of socio-economic development of the periphery. The specified factors affect the overall ‘survival’ potential of the peripheral territories. The results of the study are of practical importance and can be used as the empirical justification for program projects aimed at stimulating development of regions.

Abstract:
Esta tese trata, de forma ampla, da relação ciência e sociedade. Especificamente procura compreender o processo de construção do sistema biotecnológico em face do contexto ao qual está relacionado. A argumentação teórica estrutura-se em torno de questões levantadas pelos estudos sociais da ciência e tecnologia, e tem como marco teórico a teoria dos sistemas sociais de Niklas Luhmann, que parte da diferença sistema/entorno para compreender a relação ciência e sociedade. A questão levantada refere-se à estrutura de reprodução da ciência contemporânea e sua relação com o entorno. A hipótese argumenta que a estrutura do sistema biotecnológico sofreu uma mudança, da reprodução baseada na "verdade" à reprodução baseada no "funcionamento". Esta última forma de reprodução emerge em função das perturbações do entorno da ciência, principalmente em função do contexto caracterizado por exigências tecnológicas. Vinculadas a tais exigências estão ainda exigências de aplicação, legalidade, lucratividade, segurança, inovação. A pesquisa utilizou entrevista semi-estruturada com líderes de grupos de pesquisa em biotecnologia em seis estados da federação, e pesquisa documental, como métodos de coleta de dados, e utilizou técnicas qualitativas de análise, especificamente, a análise de conteúdo temática. De maneira mais específica, a investigação localiza-se na periferia do sistema global de ciência e tecnologia, e apresenta como a diferenciação centro/periferia também incide na reprodução do sistema biotecnológico. Para tanto, constrói-se o conceito de regime de produção de conhecimento, um regime de perturbações recíprocas entre sistemas, limitado pelas configurações institucionais dos Estados nacionais. Tal regime, no Brasil, foi caracterizado pelos sistemas do direito, da economia, da política e da ciência, e as perturbações dos três primeiros na biotecnologia é o que se investiga nesta pesquisa. Conclui-se que a pesquisa biotecnológica produz um outro tipo de verdade, a saber, a verdade eficaz.<br>This thesis deals with the relationship between science and society. It particularly seeks to understand the process of construction of biotechnology and its context. Beyond this, it searches to link biotechnology research to the global society and to the specific context of peripheral science The theoretical argument is structured around issues raised by social studies of science and technology, and uses the theoretical framework of the theory of social systems of Niklas Luhmann, who considered the difference system / environment to understand the relationship between science and society. The main question raised refers to the structure of the reproduction of contemporary science and its relation with the environment. Therefore, our hypothesis argues that the structure of the biotechnology has changed from a reproduction based on "truth" to a reproduction based on "operation". The latter form of reproduction emerges in the light of disturbances around the science, especialy in a context characterized by technological requirements. Besides theses, there are requirements for application, legality, profitability, safety and innovation. This research was conducted using semi-structured interviews with leaders of biotechnology research groups from six brazilian states. Besides, a documentary research was conducted and a thematic content analysis was performed. Particularly, this research is located at the periphery of the global system of science and technology, and presents how the differentiation center/periphery also affects the reproductive system of biotechnology. In this sense, we construct the concept of knowledge production regime, a regime of mutual disturbances between systems, which is limited by the institutional configurations of national states. In Brazil, such regime was characterized by systems of law, economy, policy and science. This research has focused on the disturbance of the first three on biotechnology. It is concluded that research biotechnology produces another kind of truth, namely truth effectively.

Abstract:
Recent political developments, with the outcome of the Brexit referendum and the election of Donald J. Trump as President of the United States, have revitalized the discussion about so called political cleavages. Drawing upon the work of Lipset and Rokkan, some see the urban-rural cleavage as an explanation to the election outcomes. In a Swedish context it is primarily the increase in electoral support for the Sweden Democrats that has brought up the question. The overarching purpose with this master’s thesis is to explain the role of Lipset and Rokkans theoretical cleavages in Swedish rural politics. Rural politics is considered a most likely-case for finding ideas related to the urban-rural cleavage, a cleavage which is said to have gained a greater importance over the past couple of years. Political cleavages exist when political actors demonstrate cohesive ideas and in a structured matter relate to them. For this reason, the thesis’ subordinate purpose is to describe what ideas parliamentary parties have in the rural political debate. This is done through an idea analysis where problems and solutions presented by the political parties are described and interpreted. The conclusion is that the worker-owner-cleavage is the dominant cleavage in Swedish rural politics. Political parties tend to problematize issues that are a part of the cleavage, with issues such as welfare, regional redistribution, entrepreneurship and taxation. The urban-rural and center-periphery cleavage can only be regarded as secondary and subordinate to the worker-owner-cleavage. However, there are ideas in the debate relating to these two cleavages. Ideas relating to the state-church cleavage is absent in the chosen material.

Abstract:
<p> The dynamics of expanding polities and relationships between cultural core groups, peripheral populations and sites in semi-peripheral areas between the two groups are important topics in studies of complex societies. One area where these distinctions are clearly identified within the settlement pattern formed by the relationship between the cultural and the natural landscape is the Tequila Valleys of Western Mexico. The Teuchitl&aacute;n culture of the Late Formative and Early Classic periods formed distinctive settlements around the edges of the valleys, which were also marginally bound to most complex social developments within the cultural core region near the center of the valleys. Semi-peripheral sites between cultural traditions are of particular interest as focal points for economic, political, and social relationships. This thesis focuses on two sites which occupied very different environments, namely Llano Grande and Las Navajas. I ask whether these sites show different degrees of emphasis on two basic economic strategies in ways which capitalized on the advantages of each site's respective environment. Specifically, did Llano Grande's relative physical isolation from the cultural core area, more distant location and differences in available resources reflect a greater reliance on trade via exported obsidian? Alternatively, did Navajas' closer relation to the core allow a continuance of the core's degree of emphasis on the staple-oriented economy, with less emphasis on obsidian production and trade than Llano Grande? This thesis draws upon the work of Earle (1991) to structure the analysis, particularly his contrast between wealth and staple finance. Past research is reviewed to develop expectations for each model, which are tested using the analysis of obsidian debitage and products within the ritual centers of each site.</p>

Abstract:
The aim of the Master's thesis is to analyze the growing interest of the global economic system centers in the region of developing countries in sub-Saharan Africa with the account on weakening position of the West in relation to this region. The thesis will be structured into two sections. The first part will focus on the relationship between the West and countries of the African continent and the circumstances allowing not only the access of new challengers, but also alternative development models. In this respect the thesis will use the theoretical works of Adrian Leftwich and Claus Offe dealing with the issues of democratization and economic development and their mutual incompatibility. The second part of the thesis will analyze relations with these emerging, non-western power centers and their alternative development models. The research question of the thesis is formulated whether these alternative centers of the global economic system in the region of sub-Saharan Africa propagate their own conception of development models, with proclaimed respect for local conditions, as a challenger to the Western concept of development policy. The hypothesis assumes a certain degree of autonomy in case of developing countries in choosing "their" partner center. These centers are forced to offer certain...

This book examines the feeling that we often refer to as ‘nostalgia’ from the perspective of writers and artists located on the (imperial, Soviet, and Post-Soviet) periphery of Russian culture who regard the center of the culture from which they have been excluded with varying degrees of longing and ambivalence. The literary and artistic texts analyzed here have been shaped by these author’s ruminations on social and psychological marginalization, a process that S. Boym has called ‘reflective nostalgia’ and that the authors of this volume also refer to as ‘toska’.

Full text
Abstract:
In A Case for Community-Centered Journalism: Solutions, Engagement, Trust, Andrea Wenzel maps out a process model for building trust—not just in journalism, but between different sectors of communities. She details how, in many communities, residents gauge trust in news not only based on factors like accuracy and credibility, but also based on how these are intertwined with the perceived motives of news media, and whether outlets are seen to represent communities respectfully. For this reason, Wenzel contends that more local journalism alone is not enough. Rather, she argues that a different kind of local journalism is needed—a community-centered journalism that is solutions-oriented and that engages and shares power with community stakeholders. Through a series of case studies across the U.S., in urban, suburban, and rural communities, Wenzel uses a communication infrastructure theory framework to explore how local journalism interventions attempt to strengthen relationships between residents, community organizations, and local media. She examines the boundary challenges to dominant journalistic practices and norms that arise from place-based interventions to build relationships of trust. Mindful of dynamics of race, class, place, and power, Wenzel recommends a process that is portable – rather than scalable -- that centers on community stakeholders, and is shaped as much by local assets as by needs. She argues that if they shift away from a model that puts journalists at the center and marginalized communities on the periphery, engaged journalism and solutions journalism have the potential to strengthen not just journalism, but the communication health of communities.

Full text
Abstract:
The World Come of Age offers a cultural history of ideas that culminated in a radical political theology forwarded by the first generation of liberation theologians. Representing those marginalized by modern politics and religion due to race, class, or sex status, liberationists built a trans-American intellectual movement. Lilian Calles Barger sets the stage in the 1960s and 1970s, as black theologian James Cone, Catholic priest Gustavo Gutiérrez, and feminists Mary Daly and Rosemary Radford Ruether led the way in bridging the gulf between the religious values of justice and equality and political pragmatism. Sharing a heightened awareness of oppression with Latin American revolutionaries, Black Power and women’s liberation movements, and a Third World consciousness, liberationists honed their theo-political impulses. They unmasked the ideas that underwrote the white/black, male/female, rich/poor ordering of the world, not only within given societies but between the political and economic center and the periphery of the modern world. Questioning the religious/political divide with its privatized religion, they reconstructed thinking about God’s relationship to the world. Combining strands of radical politics, social theory, theological antecedents, and the history and experience of subordinated groups, they challenged the legitimating role of theology that dominated the mid-twentieth century. Liberationists secularized the meaning of Christian salvation combined with enlightened notions of freedom into an integral liberation and sought to recover a religious vitalism to instigate social action. The World Come of Age demonstrates how, by redefining the theo-political public space, liberation theologians set the stage for the subsequent torrent of religious activism across the ideological spectrum.

Abstract:
This chapter argues that it was partly through engagement with the Ottoman Empire, particularly its tradition of extraterritorial consular jurisdiction, that nineteenth-century European and American jurists came to view China, Japan, and a number of other states as ‘semi-civilized’, setting them against ‘civilized’ states on the one hand and ‘savage’ peoples on the other. These states on the ‘semi-periphery’ exercise a greater degree of agency in international law, given their closeness to dominant centers of economic and intellectual production that had come under their influence, as well as their possession of national traditions and state institutions resilient enough to resist formal colonization. These traits are especially evident in the case of the Ottoman Empire, a powerful state that made a point of modifying its profile for different audiences.

This chapter argues that incidents of transformative violence in the periphery fail to generate enough public revulsion to spark an open debate about how policing must change. Vulnerable individuals in the periphery lack the connections with civil society activists, mostly concentrated in urban areas, who would advocate for their rights. Many rural-based activists and NGOs call for a police overhaul in the aftermath of these episodes of transformative violence, but their voices are not as loud or as unified as those speaking about similar events in urban areas. The national leadership’s response to outbreaks of transformative violence in rural areas aims at closing the center’s governance gap where the public rebels against unpopular local authorities. As a result, the state moves to increase the political loyalty of the local police to the center under the pretense of police reform.

Abstract:
Social science scholars have repeatedly predicted the demise of regional (or peripheral) nationalism, from the late nineteenth century to the post-World War II period and in the 1990s. However, all suggestions about the death of regional nationalism have been proven wrong. On the contrary, nationalist movements in the West have not only survived advanced capitalist development in liberal democratic contexts but have thrived as well. In the developing world, decolonization gave rise to a variety of regional nationalist movements that frequently spiraled into violent conflict and secessionist attempts. To deal with regional nationalism, states often turned to devolution, resulting in the implementation of various schemes of autonomy, most of which came under the guise of federalism. Three trends characterize the literature on regional nationalism and its management through devolution: a change in the way regional nationalism is viewed; a transformation in the type of political, institutional, and constitutional response scholars have suggested toward regional nationalism; and a willingness to accept, or even favor, secession as a possible solution to conflict in multinational and/or multiethnic countries. At the same time, there are at least two challenges in the study of regional nationalism and its management: objectivity and the need to develop a greater comparative perspective.

Abstract:
Building on a slate of recent discoveries and publications, the chapter investigates how the Macedonian kings employed letters and so-called diagrammata to interact with and to rule over cities within their reign and regions under their control. It thus brings to life the diplomatic activity between court and constituencies that defined the political culture of fourth-century BCE Macedonia: the different types of missives used by the kings yield important insights into the administrative hierarchies and institutional procedures (as well as the ‘styles’ of exercising power) that sustained royal rule. Specifically, Mari reconsiders the role and function of the epistatai (the local administrators who received the letters and were in charge of distributing the royal message): as initial addressees of the royal correspondence but frequently nominated by the local community, they mediated between centre and periphery and thus functioned as vital nodes in imperial administration.

Abstract:
AbstractSince the 2000s, Lima city shows important changes in its socio-spatial structure, decreasing the long-established opposition between the centre and the periphery, developing a more complex arrangement. Sustained national economic growth has allowed better socio-economic conditions in different areas of the city. However, high inequality still remains in the ways of production of urban space, which affects residential segregation. To identify possible changes in the segregation patterns of Metropolitan Lima, this study focuses on the spatial patterns of occupational groups, examining their causes and relation with income inequality. The analysis is based on the 1993 and 2007 census data, measuring residential segregation by the Dissimilarity Index, comparing with the Diversity Index. The results confirm trends towards increased segregation between occupational groups. Top occupational groups are concentrated in central areas, expanding into adjacent districts. Bottom occupational groups are over-represented in distant neighbourhoods. In-between, a new, more mixed, transitional zone has emerged in upgraded formerly low-income neighbourhoods. Areas of lower occupational diversity coincide with extreme income values, forming spaces of greater segregation. In the metropolitan centre–periphery pattern, the centre has expanded, while the periphery has been shifted to outer peripheral rings.

Abstract:
AbstractThis chapter uses social network analysis to visualize the fields of relations involving John Dennis, the most important critic of the first half of the eighteenth century, with the other protagonists in Alexander Pope’s satire, The Dunciad in Four Books (1743). By using visualizations generated by GraphViz, a program that creates topological graphs from sets of dyadic relations, and ShivaGraph, a tool that helps visualize large networks and navigate through them as through a map, this chapter brings to light data that is structurally embedded in the poem but not immediately legible given the large amount and complexity of information. In Dennis’s case, they reveal the competing stories told by the poem and the apparatus and the critic’s main role as the uncrowned king of The Dunciad’s textual periphery. These visualizations also highlight Dennis’s essential position as a network connector, his camp affiliations, the role played by peripheral characters in the plot network of the poem, and the main dunces targeted by Pope, or the poem’s “hall of infamy.”

Abstract:
This chapter proposes a new understanding of prehistoric art and aesthetic function. The theory of kinesthetic function is defined by three interrelated features, which are defined in this chapter. Once these features are laid out, we will then be in a better place to see how this kinesthetic field concretely emerged in the dominant arts and images of the prehistoric period. Thus, the functional field is defined first and foremost by the continuous flow of matter from the periphery toward a center. The kinetic foundations of all aesthetic fields lie in a functional materialism. There is no separate or immaterial aesthetic conciseness that can cut itself off from its material co-functionality with matter.

Full text
Abstract:
This essay contributes to developing 21st-century readings of Rhys by exploring her work in relation to more recent theories of affect, particularly those associated with Brian Massumi. Massumi's work, including his influential concept of “the autonomy of affect,” is particularly intriguing in this regard because of its potential implications for postcolonial studies. Just as postcolonial studies has in the past decade sought to move beyond the center-periphery model that has dominated the discipline since its inception, readings of Rhys invite scholars to move beyond the focus on the purported (or failed) critique of Empire that has defined postcolonial Rhys scholarship. This chapter reads the two narrators of Wide Sargasso Sea, both of whom focus heavily on how their position within the British Empire is experienced on the level of emotions and affect. Rhys challenges the rigid distinctions between emotion and affect that underlie Massumi's theories, suggesting a more complex interplay between non-cognitive experiences and ideology.

Abstract:
The research shows several key causes of the reception and literary-historical periphery of the rich literary oeuvre of the Croatian poet, essayist, storyteller and author of one drama, Sida Košutić. While much of the research to date has cited the ideological and world-view causes of Sida Košutić’s marginal position in the canon of national literature, the writer’s expression of the unspeakable at the key of the Christian mystical experience is predominantly explored here. Thus, this research fits in with the contemporary interest in the philosophy of language and literary theory in the problem of the expression of the unspeakable (L. Wittgenstein, K. Jaspers, J. Derrida, M. Sells, etc.). The prominent elements of mystical discourse in the writer’s lyrical expression are analyzed on the example of a poem (“Ime tvoje sveti se”) which brings the majoritiy of poetic techniques from the entire collection Vjerenička žetva. Mystical hermeticism is also one of the possible causes of the peripheral status of Sida Košutić’s work. However, if the interpretation includes postmodern approach to language, it can be concluded that the poetic expression goes beyond the semantic atomism (the unspeakable refers to different experiences, conditions and realities), opposing representationalism and referentialism language model. Sida Košutić’s critical subject finds its legitimacy in Christian mysticism. The work of this writer can be equally included in the poetic guidelines of Croatian modern literature of the first half of the 20th century, thus undermining the dominant notions of the center and periphery defined by the national literary canon.

Abstract:
This chapter is devoted to Latin American structuralism. The chapter summarizes centre–periphery theory as stressing the co-evolution of technological capabilities and the pattern of specialization. The centre and periphery are two different sets of countries that differ markedly in terms of this co-evolution. Firstly, the periphery is a laggard region in terms of technological capabilities with respect to the centre. Secondly, to the extent that technology is a crucial determinant of international competitiveness, the asymmetry in technological capabilities (the technology gap) shapes the set of goods the periphery can competitively produce in an open economy. This set of goods constitutes the periphery’s pattern of specialization. Thirdly, causality goes in both directions: specialization affects the learning trajectory of the periphery because what economic agents learn depends on what they currently produce and on their accumulated experience in specific sectors and technologies. In this way, specialization has an impact of its own on the technology gap.

Abstract:
Although the so-called „Vienna school“ practised an universalist approach to history of arts, their prominent acters like Alois Riegel and Max Dvořák influenced the nationalist ideas among the Central European art historians in the interwar period. An evident example of such an influence is Croatian art historian Ljubo Karaman (1886‒1971) ‒ a Vienna student who studied the art relations between center and periphery from early 1930s on. His thoughts on this topic were collected in his 1963 book Problemi periferijske umjetnosti. O djelovanju domaće sredine u umjetnosti hrvatskih krajeva (Problems of Peripheral Art. On Influence of Local Surrounding on the Art of the Croatian Areas). Colonial character of the Karaman’s definition of the center/periphery relation is clear in his notion that the dissemination and assimilation of the artistic styles is always one-way: from developed center to the province. His definition of „peripheral art“ appeared as a reaction to the works of famous „Vienna school“ scholars from early 20th century (particularly Polish-Austrian art historian Strzygowski). It is based on the idea of external, political and artistic influences in Dalmatia as external forces of artistic exchange. A prominent writer and encyclopaedist Miroslav Krleža turned upside-down the idea of the artistic transfer from the advanced West toward underdeveloped East/Balkans as a periphery at the edge of civilisation. In his discussion on the Second Congress of writers in Zagreb he promoted the idea of the periphery as a true center. During 1950s, Krleža strongly influenced the formation of a new cultural paradigm, and forging of the new scientific paradigm within art history in Croatia. In her paper, the author explores how texts of the Croatian art-history scholars regarding ancient Dalmatian art were influenced by Karaman’s and Krleža’s ideas and concepts on peripheral, provincial, and border-line art.

Abstract:
Interpersonal ties are pivotal to individual efficacy, status and performance in an agent society.This paper explores three important and interrelated themes in social network theory: the center/periphery partition of the network; network dynamics; and social integration of newcomers. We tackle the question: How would a newcomer harness information brokerage to integrate into a dynamic network going from periphery to center? We model integration as the interplay between the newcomer and the dynamics network and capture information brokerage using a process of relationship building. We analyze theoretical guarantees for the newcomer to reach the center through tactics; proving that a winning tactic always exists for certain types of network dynamics. We then propose three tactics and show their superior performance over alternative methods on four real-world datasets and four network models. In general, our tactics place the newcomer to the center by adding very few new edges on dynamic networks with ~14000 nodes.

Four hierarchical levels of center-periphery processes such as oligopolization, metropolization, regionopolization and locopolization are considered. They occur at global, regional, country, in-country regional and local levels, respectively. Center-periphery processes result in regionalization (isolation of regions) and spatial fragmentation, which generates threats to further development. They are related to stratification of space by the level and quality of life of the population, its conversion into polarized and multi-problem one, making the transition to sustainable and inclusive development an imperative of further development of the mankind.

Abstract:
Mazowieckie Province is a unique area of Poland. It is characterised by social and economic diversification. Located in this province, Warsaw strongly influences the development of neighbouring rural areas. On the other hand, rural municipalities whose socio-economic parameters are among the lowest in the country are located within several dozen kilometres from the centre of the capital. Such disparities show that Mazowieckie is characterised by large interregional differences in its internal structure. This is an interesting research area that requires the analysis of socio-economic development in this region to be conducted in a multidimensional way. The aim of this study is to evaluate the spatial differentiation of the level of socio-economic development of rural areas in Mazowieckie Province. Linear ordering was used to determine the level of socio-economic development. The results of the study are consistent with core-periphery theory. The large urban centres that function as the centres for the surrounding rural areas have the greatest impact on the level of rural development. The impact of smaller towns can also be noticed. They often are the local development centres for surrounding villages.

Abstract:
In the heavy oil process industry preheated bitumen and steam are mixed upstream of the feed nozzle and subsequently injected into fluid bed coker reactors via feed nozzles. To achieve high liquid product yields, the bitumen should contact a large number of fluidized coke particles quickly and uniformly. One of the drawbacks of the spray issuing from the nozzle is the potential pulsation within the spray and in the feeding conduit, which is highly undesirable to yield high productivity. These pulsations result in poor atomization and in most instances, a slug of liquid is ejected out of the nozzle. It would be valuable to investigate under which two-phase fluid conditions this pulsation aggravates. It would also be beneficial to examine the detailed spray map with changing air-to-liquid ratio (ALR) by mass and void fraction (α). The average void fraction in the feeding conduit was measured by a pneumatic controlled quick-closing-valve (QCV). The length and diameter of the feeding conduit was 36.8 cm and 6.35 mm, respectively. The experiments were performed using mixtures of air with water at water flow rates of 1.50 to 7.50 kg / min and air-to-liquid (ALR) mass ratios of 0.30 to 9.3%. This study indicates that there exists a strong positive correlation between the droplet diameter and axial velocity at the center of the spray. A positive correlation also exists in between the spray center and periphery. However, a strong negative correlation exists at the periphery of the spray. Knowledge from this study would help the heavy oil process industry to upgrade their heavy oil upgrading process and increase the product yield.

The main function of the nervous system is to serve the body’s control center and communications network. Each nerve consists of various elements that possess distinct anatomic and physiological properties which allow them to perform their intended roles and function as a unit. Studies have shown the endoneurium, perineurium and epineurium, comprising the successive layers of intraneural connective tissue surrounding nerve fibers, to exhibit different properties [1, 2]. It is therefore important to take this into consideration when investigating mechanical properties of nerves.

Abstract:
Tissue-engineered cartilage using a hydrogel scaffold is capable of achieving native compressive properties and glycosaminglycan (GAG) content [1]. However, these tissues are limited in their collagen production and closer inspection of the localized mechanical properties demonstrates that mature constructs consist of a stiffer periphery region surrounding a softer core [1, 2]. Nutrient diffusion becomes increasingly more challenging as the cells in the construct periphery deposit extracellular matrix. Altering the scaffold porosity by adding microscopic porogens can improve the nutrient diffusion into the center of the construct [3]. Furthermore, chondroitinase ABC (chABC) has been shown to improve collagen production of mature engineered cartilage (i.e. tissue cultured for 2–4 weeks before chABC digestion). Lipid microtubes, designed to slowly release chABC for spinal chord injury repair can be incorporated into our agarose hydrogel scaffold in a chABC-loaded or unloaded form. The objective of this study was to explore the use of lipid microtubes in our scaffold as a tubular porogen and as a vehicle to deliver chABC throughout the scaffold to improve nutrient diffusion and collagen production into our engineered constructs.

Abstract:
Two-dimensional finite element thermal simulations of a generic rail package designed to transport twenty-one spent PWR assemblies were performed for normal transport conditions. Effective thermal conductivity models were employed within the fuel assembly/backfill gas region. Those conductivity models were developed by other investigators assuming the basket wall temperature is uniform. They are typically used to predict the maximum fuel cladding temperature near the package center. The cladding temperature must not exceed specified limits during normal transport. This condition limits the number and heat generation rate of fuel assembles that can transported. The current work shows the support basket wall temperatures in the periphery of the package are highly non-uniform. Moreover the thermal resistance of those regions significantly affects the maximum fuel clad temperature near the package center. This brings the validity of the fuel/backfill gas thermal conductivity models into question. The non-uniform basket wall temperature profiles quantified in this work will be used in future numerical and experimental studies to develop new thermal models of the fuel assembly/backfill gas regions. This will be an iterative process, since the assembly/backfill model affects the predicted basket wall temperature profiles.

Abstract:
Evaluation of a critical heat flux is one of the most important issues for design of an advanced water-cooled reactor core. Since it becomes difficult to perform full-scale experiments due to a larger scale of the advanced reactor cores, an analytical approach has been widely noticed in the core design. To predict the critical heat flux in high accuracy, it is required to correctly understand a horizontal distribution of a two-phase flow in the rod bundles. In this study, the two-phase flow characteristics through narrow gaps in the tight-lattice 37-rod bundle experiment at JAERI were investigated using the subchannel analysis code, NASCA. At the center of the bundle, liquid flowed toward the periphery due to the diversion cross-flow at the elevation where boiling started and the turbulent mixing and the void drift were not influential as they can be neglected. On the periphery of the bundle, the flow mixings due to the diversion cross flow, turbulent mixing and void drift were almost the same order. Gas flowed in the same way with the liquid phase due to the diversion cross-flow, and the turbulent mixing and the void drift moved the gas in the opposite way of the liquid phase migration. An amount of the diversion cross-flow for the liquid phase increased in proportion to the square of the mass velocity. The characteristics of cross flow were almost the same in the different local power peaking and in the different gap widths in the present model.

A smartphone app displays several neuropathy questionnaires to the user to identify and monitor changes in their condition. This paper presents results from comparison between the new smart device and the gold standard Neurothesiometer. Results suggest that the new device performs closely to the gold standard in terms of the frequency and amplitude of vibration.
