Lax forms of the qq-Painlev\'e equations

All $q$-Painlev\'e equations which are obtained from the $q$-analog of the sixth Painlev\'e equation are expressed in a Lax formalism. They are characterized by the data of the associated linear $q$-difference equations. The degeneration pattern from the $q$-Painlev\'e equation of type $A_2$ is also presented.Comment: 24 page

“Once you’ve been there, you’re always recovering”: exploring experiences, outcomes, and benefits of substance misuse recovery

Purpose – Recovery is a central component of UK substance misuse policy, however, relatively little is known about the views and meanings of recovery by those experiencing it. The purpose of this paper is to explore these factors, and understand how service user experiences align to current understandings of “recovery capital”. Design/methodology/approach – This paper draws on qualitative interviews with 32 individuals from six UK recovery communities, including those commissioned by a statutory service (n=8) and a peer-led recovery community (n=24). Findings – Meanings of recovery differed between people in abstinence-based communities and those not; however, all had consistent views on their own recovery outcomes and the benefits they believed recovery brought. All viewed recovery as a process; a continuous journey with no end-point. Internal motivation, peer support, social networks and daily structure were integral to supporting individuals achieve and maintain recovery. Key benefits of recovery reflected recovery capital and included positive relationships, sense of belonging, increased self-worth and confidence, employment and education. Research limitations/implications – This research shows that recovery experiences and outcomes are not centred entirely on the individual but are wider, more holistic. Maintaining recovery involves being connected to themselves and to the wider environment: family, friends, peers and society. Although the recovery capital model has many elements that were discussed by the participants of this research, the discourse they used does not align with the model. To validly measure and quantify recovery outcomes, individuals need to identify with the measures themselves. Practical implications – From policy and commissioning perspectives, these findings suggest benefits of recovery that were viewed by participants as indicators of success: demonstrate elements which support recovery; and highlight key social value outcomes which people attribute to recovery. Social implications – These “softer”, qualitative benefits should be considered by policy-makers, commissioners, statutory and non-statutory services in order to evidence outcomes. However, it should also be recognised that a temporally static approach to assessing recovery may be in contradiction to the meaning and perspectives held by those in recovery communities who conceptualise it as a long term and ongoing process. Originality/value – This paper adds to understandings of experiences and meanings of recovery, with a particular focus on the measurement of outcomes and their meanings, and the role of abstention and continued drug use within the recovery process. © 2016, Emerald Group Publishing Limited

Globalization, the ambivalence of European integration and the possibilities for a post-disciplinary EU studies

Using the work of Manuel Castells as a starting point, this article explores the ambivalent relationship between globalization and European integration and the variety of ways in which the mainstream political science of the EU has attempted to deal with this issue. The analysis here suggests that various 'mainstreaming' disciplinary norms induce types of work that fail to address fully the somewhat paradoxical and counter-intuitive range of possible relationships between globalization and European integration. The article explores critically four possible analytical ways out of this paradox—abandonment of the concept of globalization, the development of definition precision in globalization studies, the reorientation of work to focus on globalization as discourse, and inter- and post-disciplinarity. The argument suggests that orthodox discussions of the relationship require a notion of social geography that sits at odds with much of the literature on globalization and while greater dialogue between disciplines is to be welcomed, a series of profound epistemological questions need to be confronted if studies of the interplay between global and social process are to be liberated from their disciplinary chains

DFT Calculations as a Tool to Analyse Quadrupole Splittings of Spin Crossover Fe(II) complexes

Density functional methods have been applied to calculate the quadrupole splitting of a series of iron(II) spin crossover complexes. Experimental and calculated values are in reasonable agreement. In one case spin-orbit coupling is necessary to explain the very small quadrupole splitting value of 0.77 mm/s at 293 K for a high-spin isomer

Harmonic generation in ring-shaped molecules

We study numerically the interaction between an intense circularly polarized laser field and an electron moving in a potential which has a discrete cylindrical symmetry with respect to the laser pulse propagation direction. This setup serves as a simple model, e.g., for benzene and other aromatic compounds. From general symmetry considerations, within a Floquet approach, selection rules for the harmonic generation [O. Alon Phys. Rev. Lett. 80 3743 (1998)] have been derived recently. Instead, the results we present in this paper have been obtained solving the time-dependent Schroedinger equation ab initio for realistic pulse shapes. We find a rich structure which is not always dominated by the laser harmonics.Comment: 15 pages including 7 figure
