Fat Fisher Zeroes

We show that it is possible to determine the locus of Fisher zeroes in the thermodynamic limit for the Ising model on planar (``fat'') phi4 random graphs and their dual quadrangulations by matching up the real part of the high and low temperature branches of the expression for the free energy. The form of this expression for the free energy also means that series expansion results for the zeroes may be obtained with rather less effort than might appear necessary at first sight by simply reverting the series expansion of a function g(z) which appears in the solution and taking a logarithm. Unlike regular 2D lattices where numerous unphysical critical points exist with non-standard exponents, the Ising model on planar phi4 graphs displays only the physical transition at c = exp (- 2 beta) = 1/4 and a mirror transition at c=-1/4 both with KPZ/DDK exponents (alpha = -1, beta = 1/2, gamma = 2). The relation between the phi4 locus and that of the dual quadrangulations is akin to that between the (regular) triangular and honeycomb lattices since there is no self-duality.Comment: 12 pages + 6 eps figure

The Effects of Plyometric Training on Spinal and Supraspinal Motor Control

Purpose: The purpose of this study was to determine the effects of plyometric training on spinal and supraspinal motor control in healthy active females. Methods: A 2 (Group) x 2 (Session) x 2 (Stance) mixed model design was used for homosynaptic depression (HD) and recurrent inhibition (RI) data. A 2 (Group) x 2 (Session) mixed model design was used for H:M ratios and V-waves (V:M ratios) data. Thirty-one participants were recruited to participate in the study. Participants participated in either the training or control group for 6-weeks. All participants were measured pre- and post-intervention on H:M ratios, HD, RI, and V-waves. Results: There were no statistically significant interactions for any of the dependent variables (p \u3e 0.05). There was a session main effect for RI (p = 0.01) as well as a group main effect (p = 0.01) and a stance main effect (p \u3c 0.01) for HD. Conclusions: Performing plyometric training does not modulate the spinal or supraspinal motor control based on the findings of this study. Plyometric training is not the only component that should be used in Anterior Cruciate Ligament Injury Prevention Programs to alter motor control. A more challenging and higher impact plyometric exercises are suggested to allow more demand on the neural drive of the physically active participants

All work and no pay: consequences of unpaid work experience in the creative industries

This research note evaluates the benefits and pitfalls of unpaid work as an entry route into employment in the creative industries and investigates the consequences of this practice for those who already work in the sector. Based on a qualitative study of perspectives of stakeholders in unpaid work, this article argues that the social capital thesis, often used as a rationale for unpaid work, inadequately explains the practice of unpaid work experience, primarily because it does not take cognisance of the consequences of this practice for other people working in the sector. The study also highlights methodological issues that need to be considered in the future. As well as the importance of a plurality of stakeholder perspectives, the study emphasizes the need to consider the perspectives of those who are excluded from unpaid work and those who are potentially displaced by it

Lower job satisfaction among workers migrating within Europe: A gender paradox

Intra-European migrants reported lower job satisfaction levels than native workers, in three rounds of the European Social Survey. This deficit was also experienced by their descendants (the second generation), despite the latter generation achieving native levels of household income. At least some part of these lower levels of job satisfaction was associated with a clustering into lower-productivity industries. There are striking gender differences in experiences: among men the first generation is just as likely to be satisfied with their jobs as the ‘native’ population, whilst it is the second generation who are less likely to achieve job satisfaction. For women, both generations experienced a deficit in job satisfaction. This may reflect changing expectations of work among men, and integration for women, across generations, and contrasts with the convergence in earnings over time. The country of origin, within Europe, did not seem to be associated with levels of job satisfaction

Dualization and subjective employment insecurity: Explaining the subjective employment insecurity divide between permanent and temporary workers across 23 European countries

Dualization theory posits that certain institutions cause dualization in the labour market, yet how institutions deepen the subjective insecurity divide between insiders and outsiders has not been examined. This paper examines this question using data from 23 European countries in 2008/9. Results show that the subjective employment insecurity divide between permanent and temporary workers varies significantly across different countries. Corporatist countries, with stronger unions, have larger subjective insecurity divides between permanent and temporary workers. However, this is because permanent workers feel more secure in these countries rather than because temporary workers are more exposed to feelings of insecurity
