- Dalton is a powerful general-purpose program system for the study of molecular electronic structure at the Hartree-Fock, Kohn-Sham, multiconfigurational self-consistent-field, MOller-Plesset, configuration-interaction, and coupled-cluster levels of theory. Apart from the total energy, a wide variety of molecular properties may be calculated using these electronic-structure models. Molecular gradients and Hessians are available for geometry optimizations, molecular dynamics, and vibrational studies, whereas magnetic resonance and optical activity can be studied in a gauge-origin-invariant manner. Frequency-dependent molecular properties can be calculated using linear, quadratic, and cubic response theory. A large number of singlet and triplet perturbation operators are available for the study of one-, two-, and three-photon processes. Environmental effects may be included using various dielectric-medium and quantum-mechanics/molecular-mechanics models. Large molecules may be studied using linear-scaling and massively parallel algorithms. Dalton is distributed at no cost from for a number of UNIX platforms.

- We calculated input of organic carbon to the unproductive, brackish water basin of the Gulf of Bothnia from rivers, point sources and the atmosphere. We also calculated the net exchange of organic carbon between the Gulf of Bothnia and the adjacent marine system, the Baltic Proper. We compared the input with sinks for organic carbon; permanent incorporation in sediments and mineralization and subsequent evasion of CO2 to the atmosphere. The major fluxes were riverine input (1500 Gg C year(-1)), exchange with the Baltic Proper (depending on which of several possible DOC concentration differences between the basins that was used in the calculation, the flux varied between an outflow of 466 and an input of 950 Gg C year(-1)), sediment burial (1100 Gg C year) and evasion to the atmosphere (3610 Gg C year(-1)). The largest single net flux was the emission of CO2 to the atmosphere, mainly caused by bacterial mineralization of organic carbon. Input and output did not match in our budget which we ascribe uncertainties in the calculation of the exchange of organic carbon between the Gulf of Bothnia and the Baltic Proper, and the fact that CO2 emission, which in our calculation represented 1 year (2002) may have been overestimated in comparison with long-term means. We conclude that net heterotrophy of the Gulf of Bothnia was due to input of organic carbon from both the catchment and from the Baltic Proper and that the future degree of net heterotrophy will be sensible to both catchment export of organic carbon and to the ongoing eutrophication of the Baltic Proper.

Impossible Interculturality? : Education and the Colonial Difference in a Multicultural World
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- An increasing number of educational policies, academic studies, and university courses today propagate ‘interculturality’ as a method for approaching ‘the Other’ and reconciling universal values and cultural specificities. Based on a thorough discussion of Europe’s colonial past and the hierarchies of knowledge that colonialism established, this dissertation interrogates the definitions of intercultural knowledge put forth by EU policy discourse, academic textbooks on interculturality, and students who have completed a university course on the subject. Taking a decolonial approach that makes its central concern the ways in which differences are formed and sustained through references to cultural identities, this study shows that interculturality, as defined in these texts, runs the risk of affirming a singular European outlook on the world, and of elevating this outlook into a universal law. Contrary to its selfproclaimed goal of learning from the Other, interculturality may in fact contribute to the repression of the Other by silencing those who are already muted. The dissertation suggests an alternative definition of interculturality, which is not framed in terms of cultural differences but in terms of colonial difference. This argument is substantiated by an analysis of the Latin American concept of interculturalidad, which derives from the struggles for public and political recognition among indigenous social movements in Bolivia, Ecuador and Peru. By bringing interculturalidad into the picture, with its roots in the particular and with strong reverberations of the historical experience of colonialism, this study explores the possibility of decentring the discourse of interculturality and its Eurocentric outlook. In this way, the dissertation argues that an emancipation from colonial legacies requires that we start seeing interculturality as inter-epistemic rather than simply inter-cultural.

Austere histories in European societies : social exclusion and the contest of colonial memories
- 2016
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Austere Histories in European Societies discusses how the current economic and political crisis in Europe affects not just our present but also our views and interpretations of the past. The contributions to the book examine a firmly defined problem: in which ways do crisis and decline in contemporary Europe trigger a selective forgetting and remodelling of the past? This problem is addressed through a set of questions, which the contributors to the collection address at various levels:How do present policies of austerity and the ensuing social exclusion of migrants and minorities influence the perceptions and interpretations of the place of minorities, migrants and colonized peoples in European history?How do new regimes of historiography and memory culture relate to emerging and established patterns of discrimination and social segmentation in today’s European societies? In seeking to answer these questions, the book makes a strong contribution to a European-wide discussion on the backlash against multiculturalism, diversity, and immigration, and on changing interpretations of the imperial and colonial systems that have shaped Europe’s position in the world.The point of departure for the collection is the recent turn of European societies toward more austere political regimes, entailing budget cuts, deregulation of labour markets, restrictions of welfare systems, securitization of borders, and new regimes of migration and citizenship. In the wake of such changes, new forms of social inclusion and exclusion appear that are justified through a reactivation of differences of race, class and gender. Against this backdrop, the book investigates contemporary understandings of history and cultural memory. Are we witnessing a turn toward austerity also in theories and practices of historiography, as well as in pedagogies of history? Can we speak of an austere historiography, an enforcement of conformity on Europe past and present?The contributions to the book examine, in both national and comparative perspective, how this development entails a privileging of certain narratives of the European past, whereas other parts of the cultural heritage are being weeded out. Strong interests are apparently at work to purge the histories of specific European nations, but also those of Europe, the West, and globalization from cultural plurality. The authors also discuss how heroic and homogeneous stories about the past of nations, regions, institutions and religions are being retold, reinvented, and re-launched. The book thus explores to what extent history (including public debate on history and history education) is again becoming “nationalistic”, and to what extent Europe’s proclaimed “cosmopolitanism” is being narrowed down so as to simply celebrate the achievements of Europe and posit the West as a model of universality to be emulated by others.Most chapters in the book focus on debates on history and colonial legacies in Britain, France, Netherlands, Denmark, Portugal, Sweden and Germany. They show how an increasing number of historians and intellectuals are again becoming blind to less gratifying parts of Europe’s history. While it is still too early to speak of a historical revisionism in the strict sense (for there are also strong counter-tendencies in parts of the academic community and postcolonial and migrant communities and organizations), the authors nonetheless argue that a transformation is under way, corresponding to a new politics of austerity that seems impatient with both democracy and the complexities of past. Among the sacrifices of this tendency are multiculturalism, postcolonial memories, and minority discourses of all kinds. What is lost is thus the very complexity and contradictoriness of Europe and the West. Especially, colonial and postcolonial memories are evicted from their recently claimed habitats in the European past, and again placed at the outskirts, far beyond the limit of the Western world. There is thus a strong correlation, which this collection aims to extract and analyze, between the ways in which migrant and migrant labourers are treated by present policies and the ways in which memories and experiences of migrants, minorities and colonized peoples are treated in historiography, historical pedagogy, and cultural heritage institutions.

Challenging cultures of rejection
- 2022

Tidskriftsartikel (refereegranskat)abstract
- In this article, Bojanic, Jonsson, Neergaard and Sauer present a synthetic overview of the five country cases included in the special issue that analyse the emergence of cultures of rejection since 2015. In general, they discuss the conceptual framework of ‘Cultures of Rejection’, elaborated throughout the issue as a more encompassing approach that is sensitive to the values, norms and affects that underlie different or similar patterns of exclusion and rejection in different contexts. These cultures are located in the everyday lives of people. The article, therefore, first identifies contexts, objects of rejection—often migrants and racialized Others, but also ‘the political’ or state institutions—narratives and components of cultures of rejection that we label reflexivity, affect, nostalgia and moralistic judgement. The contrasting reading of the five cases shows that people struggle for agency under precarious and insecure conditions, and fight against imagined enemies. As Bojanić, Jonsson, Neergaard and Sauer conclude, cultures of rejection mirror ongoing processes of neoliberal dispossession, authoritarization and depolitization that culminate in a wish for agency and resovereignization. Second, and based on this overview, trends in cultures of rejection are detected against different national contexts as well as against common trends of social and economic transformations and crises, such as, for instance, the COVID-19 pandemic. This results, finally, in a discussion of ways of challenging the cultures of rejection towards more democratic and solidaristic societies. One starting point might be the ‘re-embedding’ of the economy in society, that is, a more equal distribution of resources and future perspectives.

A complete parameterized complexity analysis of bounded planning

Tidskriftsartikel (refereegranskat)abstract
- The propositional planning problem is a notoriously difficult computational problem, which remains hard even under strong syntactical and structural restrictions. Given its difficulty it becomes natural to study planning in the context of parameterized complexity. In this paper we continue the work initiated by Downey, Fellows and Stege on the parameterized complexity of planning with respect to the parameter "length of the solution plan." We provide a complete classification of the parameterized complexity of the planning problem under two of the most prominent syntactical restrictions, i.e., the so called PUBS restrictions introduced by Backstrom and Nebel and restrictions on the number of preconditions and effects as introduced by Bylander. We also determine which of the considered fixed-parameter tractable problems admit a polynomial kernel and which do not. (C) 2015 Elsevier Inc. All rights reserved.
