Complexity: Some Remarks about a Classical Aesthetic Concept

The connection between autonomous art and complexity has been extensively and deeply studied in literary theories in the 20th century. The rise of aesthetic autonomy implies the complexity of literary work as the concept of a sealed container arises from the relationship between the parts that make it up. In this model, the interpretation subject works to directly face literary texts. Instead of pursuing the author’s intention, it aims to reproduce the richness and subtlety of the aesthetic state, and consider the richness and subtlety revealed in the maximum amount of text details in literary works, even if procedurally deviating from the way of mainstream understanding. There is increasing skepticism about the consequences of the autonomous aesthetics, which has been coerced by the development of contemporary capitalism, and it is necessary to develop new forms of aesthetics to reflect the changing social situation.     

Schematising hospitality: Ai WeiWei’s activist artwork as a form of dark travel

The article provides a holistic appraisal of activist-artist Ai WeiWei’s work. It argues that, despite its topical innovations and evolution, it continues to be informed by narratives of ‘hospitality’ as an experiential form of engagement with variations of otherness (father, migrant, tourist and refugee). Dividing Ai’s artwork into two overlapping phases of development (national and international/global), it considers the artist’s construction of a cosmopolitan identity with uses of ‘technology’ as embodied and communal property. As Ai’s work on the refugee crisis on Lesbos attests, his (dark) artistic cosmopolitan symbolisations use geo-political imaginaries of justice and hospitality in subsequent projects.     

An improved algorithm for the triples test

An algorithm, in the form of a Fortran subroutine TRIPLE, is given to compute statistics for the triples test for symmetry, The computational complexity of the algorithm is O(n²) which is an improvement over the straight for ward method, which is O(n³).     

ADAPTING THE MODEL: THERAPEUTIC WORK WITH CHILDREN FROM ARMY FAMILIES

This paper describes the development of a specialised therapeutic service for parents and their young children in an inner city social services family centre. The Under five's counselling service, based on the Tavistock Model, offers brief psychoanalytic interventions to parents who are worried about their young child's development e.g. crying, eating, persistent crying etc. The premise behind setting up such a service was to provide therapeutic intervention to the parent-child relationship at the earliest possible stage, preventing further ongoing difficulties. The paper draws upon observations and interventions with families I have seen in the first year the service was opened. Particular themes which emerged in the work with these families will be highlighted. In particular a link is made between early childhood difficulties and unresolved loss in the mother's lives. Furthermore, the impact of the service upon the rest of the social services family support services is commented upon.     

The Interface of Racial Identity Development with Identity Complexity in Clinical Social Work Student Practitioners

This paper examines the influence that one's racial identity development plays in the overall professional identity development of clinical social work student practitioners. The author discusses race, as a construct, in a post-modern world. Utilizing Saari's (1993, 2000) discussion of identity complexity, the paper demonstrates how the ability to dialogue about issues of race, in a complex and multi-faceted way, is reflective of evolution in one's racial identity development. To further one's identity development, the importance of a dialogical mode of interaction (Bahktin, 1986, 1993) is emphasized.     

The Steiner Tree Problem in Kalmanson Matrices and in Circulant Matrices

We investigate the computational complexity of two special cases of the Steiner tree problem where the distance matrix is a Kalmanson matrix or a circulant matrix, respectively. For Kalmanson matrices we develop an efficient polynomial time algorithm that is based on dynamic programming. For circulant matrices we give an -hardness proof and thus establish computational intractability.     

On the Complexity of Constructing Evolutionary Trees

In this paper we study a few important tree optimization problems with applications to computational biology. These problems ask for trees that are consistent with an as large part of the given data as possible. We show that the maximum homeomorphic agreement subtree problem cannot be approximated within a factor of , where N is the input size, for any 0 in polynomial time unless P = NP, even if all the given trees are of height 2. On the other hand, we present an O(N log N)-time heuristic for the restriction of this problem to instances with O(1) trees of height O(1) yielding solutions within a constant factor of the optimum. We prove that the maximum inferred consensus tree problem is NP-complete, and provide a simple, fast heuristic for it yielding solutions within one third of the optimum. We also present a more specialized polynomial-time heuristic for the maximum inferred local consensus tree problem.
