London South Bank University is a public university located in Southwark, London, United Kingdom. It has over 19,000 students and 1,700 staff, and is based in the London Borough of Southwark, near the South Bank of the River Thames, from which it takes its name.Founded from charitable donations in 1892 as the "Borough Polytechnic Institute", it absorbed several other local colleges in the 1970s and 1990s, and achieved university status in 1992. LSBU is a post-1992 or new university.The current Chancellor is investor Richard Farleigh and their Vice-Chancellor is Prof David Phoenix. Wikipedia.


This paper proposes a dynamic nonlinear state-space model with a neural network that uses a sequential learning algorithm capable of online simulation, in which the model predicts and adapts to the arrival of each new item of hydrological data in a sequential manner (as opposed to a 'batch'), thereby enabling online real-time hydrological modeling. The improved sequential extended Kalman filtering (EKF) learning algorithm is developed to train multi-layer perceptron (MLP) neural networks, and is known as the MLP-EKF method with updating of noise covariance (MLP-EKFQ). It is herein proposed to allow the evolution of the weight of a neural network sequentially in time while also computing the noise covariance matrices of the EKF algorithm automatically by maximizing the evidence density function with respect to the noise covariance matrices.The proposed MLP-EKFQ was used to develop an online real-time warning system to predict river temperatures affected by the discharge of cooling water 1. km downstream of a thermal power station, from real-time to 2. h ahead, sequentially on the arrival of each new item of hydrological, meteorological, and power station operational data at 10. min intervals. It is demonstrated that the proposed MLP-EKFQ is superior in terms of both model performance and computational efficiency to those models that adopt a batch learning algorithm such as a multi-layer perceptron (MLP) system trained using the back-prorogation learning algorithm (MLP-BP), or an adaptive neural-fuzzy inference system (ANFIS). Due to its computational efficiency, its online simulation capability, and the high levels of accuracy achieved by the proposed MLP-EKFQ method, there is a great deal of potential for its use as an online dynamic hydrological modeling tool that may be suitable for a variety of complex dynamic and/or real-time tasks. © 2012 Elsevier B.V.

Shushu is a Turkish Cypriot drag performance artist and the article begins with a discussion of a short film about him by a Greek Cypriot playwright, film maker, and gay activist. The film is interesting in its own right as a documentary about a complex personality, but it is also relevant to wider discussion of sexual and gender identity and categorization in a country divided by history, religion, politics, and military occupation. Shushu rejects easy identification as gay or transgender, or anything else. He is his own self. But refusing a recognized and recognizable identity brings problems, and I detected a pervasive mood of melancholy in his portrayal. The article builds from this starting point to explore the problematic nature of identities and categorizations in the contemporary world. The analysis opens with the power of words and language in defining and classifying sexuality. The early sexologists set in motion a whole catalogue of categories which continue to shape sexual thinking, believing that they were providing a scientific basis for a more humane treatment of sexual variations. This logic continues in DSM-5. The historical effect, however, has been more complex. Categorizations have often fixed individuals into a narrow band of definitions and identities that marginalize and pathologize. The emergence of radical sexual-social movements from the late 1960s offered new forms of grassroots knowledge in opposition to the sexological tradition, but at first these movements worked to affirm rather than challenge the significance of identity categories. Increasingly, however, identities have been problematized and challenged for limiting sexual and gender possibilities, leading to the apparently paradoxical situation where sexual identities are seen as both necessary and impossible. There are emotional costs both in affirming a fixed identity and in rejecting one. Shushu is caught in this dilemma, leading to the pervasive sense of loss that shapes the film. © 2015, Springer Science+Business Media New York. Source

Problematic Internet use (PIU), which has become a global social issue, can be broadly conceptualized as an inability to control one's use of the Internet which leads to negative consequences in daily life. The aim of this paper is to give a brief overview of the gradually evolving body of literature on PIU. This shows that the definitions and diagnostic criteria that have been proposed, and the assessment tools that have been developed, stress similarities between PIU, addictive behaviours and impulse-control disorders. Disagreements regarding diagnostic criteria and the lack of large epidemiological studies have resulted in difficulties in establishing the prevalence of PIU in the general population. Studies suggest high comorbidity rates between PIU and numerous psychiatric disorders highlighting the importance of focusing on comorbidity in treatment. There is growing evidence that genetic, personality and individual differences in automatic and controlled aspects of self-regulation may promote the development of PIU. Pharmacological and psychotherapeutic treatments specific to PIU have received limited testing in large, rigorous studies however preliminary evidence suggests that both psychotropic medications (Escitalopram, Naltrexone and Methylphenidate) and cognitive behaviour therapy may have some utility in the treatment of PIU. More research is needed on areas which remain unclear and contribute to the prognosis of PIU, in particular the temporal relationships between psychiatric disorder and PIU, mechanisms of comorbidity and the more subtle psychological changes that occur through Internet use. © 2013 Elsevier Ltd.

This paper will examine the views and experiences of Black youths living in socially deprived areas of London in order to examine the way in which they recognise the term 'Black neighbourhood' as a resource for ethnic identity formation and collective mobilisation. Despite the apparent problems that are typically associated with 'Black neighbourhoods' for many Black youths, these neighbourhoods also represent urban spaces through which a range of bonding social capital resources are generated including ties of reciprocal trust, solidarity and civic participation. These spaces hold intrinsic value for these young people providing them with a sense of wellbeing and belonging. However, the analysis will also show that the young people's experiences of the neighbourhood are not always positive ones, and such spaces create negative outcomes for Black youths residing there. In particular, the data will highlight the restrictive capacity of 'Black neighbourhoods' and the various ways in which they limit Black youths' opportunities to 'get on' in terms of social mobility and their ability to move beyond neighbourhood boundaries. © 2013 Urban Studies Journal Limited.

An analysis of swimming patterns in the ciliate Paramecium shows that the ability to swim preferentially upwards (negative gravitaxis) is primarily the result of upwardly curving trajectories. The trajectory characteristics are consistent with those produced by mechanical orientation. Cell profile measurements from microscope images suggest that the characteristic front-rear body asymmetry accounts for the observed orientation rates. Gravikinesis may result from interactions between the propelling cilia and the sedimentary flow around the cell, and it seems unlikely that an internal physiological gravity receptor exists in Paramecium. © 2010.
