Contemporary complexity sciences claim a literal, non-metaphorical applicability to physical, economic, social and cultural events. They envision the development of a general social or historical physics. Conversely, in the social sciences and humanities, complexity sciences have been typically treated as a source of new metaphors or tropes to be used in theory-building. Can there be a critical social or historical physics that is not a world-view and that does not treat science as a source of metaphors? The Lorenz attractor figures centrally in the history of complexity science as a popular image of ‘deterministic chaos’ and the ‘butterfly effect’, as an indication of how far complexity science has progressed in the last two decades, and, as this article argues, as an event whose multiplicity of interpretations attests to the problem it raises, the problem of generality associated with complexity. Via the Lorenz attractor, the article examines three attempts to treat complexity non-metaphorically in recent theoretical work (Delanda; Massumi; Stengers). In these accounts, the attractor performs several different functions. It forms part of a re-engineered concept of multiplicity, it helps conceptualize feeling or sensitivity, and it raises the general problem of practice in theory-building.

Charlottesville: University of Virginia Press, 1998. xii + 197 pp. (Cloth US$ 42.50, Paper US$ 18.50)In his most recent theoretical work, Traite du Tout-Monde, Edouard Glissant stresses the virtues of what he calls "archipelagic thinking." "The entire world is becoming an archipelago," he asserts (1997:194), and for this reason we need to distance ourselves from both insular and continental ways of thinking if we are to register the complexities of that global creolization process. The archipelago is situated between the solitary confines of the islands that constitute it and the expansive territory of the mainland toward which it points, relating the one to the other while retaining its own indeterminately distinct identity. For Glissant, actual archipelagos such as the Caribbean are exemplary sites for understanding the complex new relations that ambivalently and chaotically join together all the hitherto unconnected parts of the world. As a consequence of this, the need for understanding the Caribbean as an archipelago becomes ever more pressing: the Caribbean must be considered in its archipelagic totality, as a region that can only be adequately understood through comparative, cross-cultural analysis focusing less on its discrete parts than on the way these parts exist in relation with and to one another.

Scattering Matrix Elements

Recent theoretical work has shown that the complete set of polarized elastic light-scattering studies should yield information about scatterer structure that has so far hardly been utilized. We present here calculations of angular dependences of light-scattering matrix elements for spheres near the Rayleigh and Rayleigh-Gans-Debye limits. The significance of single matrix elements is documented on examples that show how different matrix elements respond to changes in particle parameters. It appears that in the small-particle limit (Rg/λ < 0.1) we do not loose much information by ignoring "large particle" observables.

AbstractI survey recent theoretical work on the structure of the magnetospheres of rotation-powered pulsars, within the observational constraints set by their observed spindown, their ability to power synchrotron nebulae and their ability to produce beamed collective radio emission, while putting only a small fraction of their energy into incoherent X- and gamma radiation. I find no single theory has yet given a consistent description of the magnetosphere, but I conclude that models based on a dense outflow of pairs from the polar caps, permeated by a lower density flow of heavy ions, are the most promising avenue for future research.

Abstract This article uses Joan Baez's impersonations of Bob Dylan from the mid-1960s to the beginning of the twenty-first century as performances where multiple fields of complementary discourse converge. The article is organized in three parts. The first part addresses the musical details of Baez's acts of mimicry and their uncanny ability to summon Dylan's predecessors. The second considers mimicry in the context of identity, specifically race and asymmetrical power relations in the history of American popular music. The third and final section analyses her imitations in the context of gender and reproductive labour, focusing on the way various media have shaped her persona and her relationship to Dylan. The article engages critical theoretical work informed by psychoanalysis, post-colonial theory, and Marxist feminism.

We review the remarkable properties, including superconductivity, charge-density-wave ordering and metal–insulator transitions, of lead- and potassium-doped barium bismuthate. We will discuss some of the early theoretical studies of these systems. Our recent theoretical work, on the negative-U, extended-Hubbard model for these systems, will also be described. Both the large- and intermediate-U regimes of this model were examined, using mean-field and random-phase approximations, particularly with a view to fitting various experimental properties of these bismuthates. On the basis of our studies, we point out possibilities for exotic physics in these systems. We also emphasize the different consequences of electronic and phonon-mediated mechanisms for the negative U. We show that, for an electronic mechanism, the semiconducting phases of these bismuthates must be unique, with their transport properties dominated by charge±2eCooperon bound states. This can explain the observed difference between the optical and transport gaps. We propose other experimental tests for this novel mechanism of charge transport and comment on the effects of disorder.

Consensus Decision Making

Purpose – The purpose of this paper is to trace the implementation of biculturalism in the New Zealand Playcentre Federation between 1989, when a public commitment to The Treaty of Waitangi was made, and 2011, when Tiriti-based co-presidents were elected. Design/methodology/approach – The data were drawn from the Playcentre Journal and papers from Playcentre National meetings, as well as from the author's experience as a Pākehā participating in Playcentre. The events are analysed using democratic theory. Findings – Despite a willingness to encompass biculturalism, the processes of democracy as originally enacted by Playcentre hindered changes that allowed meaningful rangatiratanga (self-determination) by the Māori people within Playcentre. The factors that enabled rangatiratanga to gain acceptance were: changing to consensus decision making, allowing sub groups control over some decisions, and the adult education programme. These changes were made only after periods of open conflict. The structural changes that occurred in 2011 were the result of two decades of persistence and experimentation to find a way of honouring Te Tiriti within a democratic organisation. Social implications – The findings suggest that cultural pluralism within a liberal democratic organisation is best supported with an agonistic approach, where an underlying consensus of world view is not assumed but instead relies on a commitment by the different cultures to retaining the political association within the structure of the organisation. Originality/value – Many organisations in New Zealand, especially in education, struggle to implement biculturalism, and the findings of this study could be useful for informing policy in such organisations. This history of Playcentre continues from where previous histories finished.

Morasko University Campus in Poznań – origin, spatial and functional structure, transport solutions The purpose of the paper is to characterize the most recently created part of the Adam Mickiewicz University – the Morasko Campus. The paper consists of three parts. The first concerns the origins and development of the campus. The second part presents its spatial and functional structure on the basis of a field inventory, while the third one – campus transport solutions based on a survey conducted among students. The history of the campus located in the northern, peripheral part of the city began with laying the foundation act and the cornerstone in 1977. The agricultural role of this area, dominant until the 1980s, has been replaced with new functions, mainly academic and scientific ones. The first university buildings were commissioned in the 1990s, and the construction boom began after 2000. A total of nine faculties (out of 21 existing) are housed in eight buildings in the campus, including exact and natural sciences, as well as a part of social sciences and humanities. To this day, neither student dormitories nor accommodation for PhD students have been constructed (although they are likely to be built), which would emphasize the academic function of the campus. The campus also comprises areas with recreational, sports, residential and other service functions (e.g. catering, beauty, hairdressing, and commercial services), which are complemented by areas that serve transport functions. Location in the northern periphery of the city, and above all the railway line for freight (the northern bypass of Poznań) separating the city from the campus, makes transport to this part of the city limited. The results of the survey revealed a lack of a safe bicycle path between the western and eastern part of the campus, insufficient number of parking places for motorists, a lack of paved roads from the north and west, only three narrow access roads for car commuters, and difficult access by public transport to the eastern and north-eastern parts. In the latter case, the planned extension of the tram line towards Umultowo after the year 2022 is expected to solve the problem. Zarys treści: Celem opracowania jest charakterystyka najmłodszej przestrzeni Uniwersytetu im. Adama Mickiewicza – Kampusu Morasko. Opracowanie składa się z trzech zasadniczych części. Pierwsza część artykułu dotyczy genezy powstania i rozbudowy miasteczka uniwersyteckiego. W drugiej części przedstawiono strukturę przestrzenno-funkcjonalną kampusu w oparciu o inwentaryzację terenową, w trzeciej zaś obsługę transportową na podstawie badań ankietowych przeprowadzonych wśród studentów. Historia położonego w północnej, peryferyjnej części miasta kampusu rozpoczęła się od wmurowania aktu erekcyjnego i kamienia węgielnego w 1977 r. Dominująca do lat 80. XX w. funkcja rolnicza tego obszaru została zastąpiona przez nowe funkcje, głównie akademickie i naukowe. Pierwsze budynki dydaktyczne oddano do użytku dopiero w latach 90. ubiegłego wieku, a boom budowlany rozpoczął się po roku 2000. Swoją siedzibę znalazły tutaj nauki ścisłe i przyrodnicze, a także część nauk społecznych i humanistycznych, w sumie dziewięć wydziałów (na 21 istniejących) w ośmiu budynkach. Do dzisiaj nie wybudowano akademików czy domu doktoranta (choć istnieją realne szanse na ich powstanie), co podkreśliłoby funkcję akademicką kampusu. W strukturze kampusu wyróżnia się ponadto obszary o funkcjach rekreacyjnych, rekreacyjno-sportowych, mieszkaniowych i innych o charakterze usługowym (np. usługi gastronomiczne, kosmetyczne, fryzjerskie, handel), których uzupełnieniem są obszary o funkcjach komunikacyjnych. Położenie na północnych peryferiach miasta, a przede wszystkim linia kolejowa dla przewozów towarowych (północna obwodnica Poznania) oddzielająca miasto od kampusu sprawiają, że obsługa transportowa tej części miasta jest ograniczona. Wyniki badań ankietowych wskazują na brak bezpiecznej drogi rowerowej między zachodnią i północno-wschodnią częścią kampusu, niewystarczającą liczbę miejsc parkingowych dla zmotoryzowanych, brak utwardzonych dróg od strony północnej i zachodniej, zaledwie trzy wąskie wjazdy na kampus dla dojeżdżających samochodem czy utrudniony dojazd komunikacją publiczną do części wschodniej i północno-wschodniej. W tym ostatnim przypadku rozwiązaniem ma być planowana po 2022 r. rozbudowa linii tramwajowej w kierunku Umultowa.

Theories of social collapse are not only the views that characterize ?societies deep in crisis?, but rather an expression of lack of belief in prosperity and central importance of the civilization in which we live. These theories follow processes of degradation of human societies, the decline of civilization`s powers and the loss of its cultural values resulting in their complete disappearance. This paper defines the subject of study and provides an overview of the history of these theories and their contemporary types by taking the main causes of collapse criteria as the basis for theory building. After the review of contemporary multi-factor analysis of collapse, mainly within the science of complex systems, full attention is focused on two atypical, yet very productive, contemporary theories of social collapse that are elaborated in detail: Jared Diamond`s theory, which studies social collapses by observing relations of other variables that can lead to collapse with environmental problems as central; and Peter Turchin`s theory which, revitalizing with modern scientific achievements Ibn Khaldun`s classical theory of ?asabia? (group feeling, spirit of community), sees social collapses as a consequence of the decline of cohesion provided by asabia. The final part of the work gives a critical review of these two theories and their relation with classical theories of social collapse (primarily those of Arnold Toynbee) and points to their mutual productive complementarity.

The history of relations of the Sheptytskyj family and the Jewish people reaches back to those remote times when the representatives of the Sheptytskyi lineage held high and honorable secular and clerical posts, and the Jews, either upon invitation of King Danylo of Halych or King Casimir the Great, began to build up their own world in Halychyna. Throughout the whole life of Metropolitan Sheptytskyi and Blessed Martyr Klymentii, a thread of cooperation with the Jews is traceable. It should be noted that heroic deeds of the Sheptytskyi Brothers to save Jews during the Second World War were not purely circumstantial: they were preceded by a long-standing deep relationship with representatives of Jewish culture. In addition, the sense of responsibility of the Spiritual Pastor, as advocated by the Brothers, extended to all people of different religions and genesis with no exception. The world-view principles of Metropolitan Sheptytskyi are important for us in order to understand what was going on in the then society in attitude to the Jews. Also, of importance is the influence of the Metropolitan on Kasymyr Sheptytskyi, later Fr. Klymentii, because the Archbishop was not only his Brother, but also a church authority and the leader. And if from under the Metropolitan Sheptytskyi’s pen letters and pastorals were published, they were directives, instructions, edifications and explanations for the faithful and the clergy, and not at all, the products of His own reflections or personal experiences, which Archbishop Andrey wanted to share with the faithful. On the grounds of the available archive materials, an effort to reconstruct the chief moments of those relations was undertaken, aiming among others, to illustrate the fact that the saving of Jews during the Holocaust was not incidental, nor with any underlying reasons behind, but a natural manifestation of a good Christian tradition of «Love thy Neighbor», to which the Sheptytskyj were faithful. Keywords: Andrey Sheptytskyi, the Blessed Hieromartyr Klymentii Sheptytskyi, Jews, the Holocaust, Galicia, Righteous Among the Nations.

Total Community

The point of the author’s research interest is mechanisms for the formation of a private religious community on the example of the Intersession brotherhood. A group of believers was emerged as part of the revival of the Orthodox life of the Kama region, but transformed into specific organization with features of popular religion, new religious movements and so-called “historical sects.” Author reconstructs the history of the community involving elements of the biographical method. The study is based on interviews and correspondence with former members of the community, close people of the residents of the commune, as well as analysis of the materials of the closed group on the social network, some audio of the groups’ seminars, photocopies of the working notebooks of the group and a series of photographs made by the believers. The investigation is based on the theoretical constructions of E. Goffman and the concept of total community. Intersession brotherhood appears as a community with the features of totality – territorial and communication closure of the residents, their employment in internal jobs, perception of the group as a family. Lack of privacy is combined with the presence of “mother-child” connection to the leader. The practice of naming for adults, the creation of new marriages, participation in gender-oriented councils create a special micro-environment with the unification of the world view. The system of privileges for advanced residents is supplemented by a developed system of fines. It makes possible to speak about special tools that lead to a change of values, a narrowing of the set of social roles and a reduction of critical thinking.
