The worker branch in Yorkshire as a way of organising Polish migrants: exploring the process of carving out diasporic spaces within the trade union structure

While post-2004 Polish labour migration to the UK was underpinned by diasporic spaces instrumental in facilitating social and labour market adjustments, the institutions of the host society such as trade unions also sought to establish links with migrants. The analysis of interactions between UK unions and EU migrants focused on organising strategies and specific provisions such as English language learning. However, the discussion tended to ignore the impacts of diasporic influences, from ethnicity and native languages of migrants to the outcomes of migrant worker organising. Drawing on ethnographic and qualitative data, this paper discusses how Polishness, in its ethnic, historic and linguistic manifestations, has affected the internal dynamics of a migrant worker organisation created by a major UK trade union. The explicit acknowledgement of diasporic particularities of post-2004 Polish migrants not only enabled labour organising activities but also shaped the migrant worker organisation from within. The strength of diasporic influences on one hand and the chosen form of union organising on the other created conditions for the development of diasporic spaces within the institution of the host society

First results from the asymmetric O(a) improved Fermilab action

We present first results from calculations using O(a) improved (FNAL) space-time asymmetric action on a 12^3 x 24 quenched lattice at \beta = 5.7 and c_SW = 1.57. The asymmetry parameter is determined non-perturbatively from the energy-momentum dispersion relation. This improvement scheme is mass dependent, and the calculations have been done in the charm and bottom quark mass sectors since it is at these heavier masses that the asymmetry is expected to be relevant.Comment: 3 pp. LaTeX2e, 6PostScript figures, uses espcrc2.sty.

Rapport building and witness memory: Actions may ‘speak’ louder than words

Building rapport during police interviews is argued as important for improving on the completeness and accuracy of information provided by witnesses and victims. However, little experimental research has clearly operationalised rapport and investigated the impact of rapport behaviours on episodic memory. Eighty adults watched a video of a mock crime event and 24-hours later were randomly allocated to an interview condition where verbal and/or behavioural (non-verbal) rapport techniques were manipulated. Memorial performance measures revealed significantly more correct information, without a concomitant increase in errors, was elicited when behavioural rapport was present, a superiority effect found in both the free and probed recall phase of interviews. The presence of verbal rapport was found to reduce recall accuracy in the free recall phase of interviews. Post-interview feedback revealed significant multivariate effects for the presence of behavioural (only) rapport and combined (behavioural + verbal) rapport. Participants rated their interview experience far more positively when these types of rapport were present compared to when verbal (only) rapport or no rapport was present. These findings add weight to the importance of rapport in supporting eyewitness cognition, highlighting the potential consequences of impoverished social behaviours for building rapport during dyadic interactions, suggesting ‘doing’ rather than simply ‘saying’ may be more beneficial

Rapport building with offenders in probation supervision: The views of English probation practitioners

Rapport-based supervision in probation is linked to positive behavioural change and reduced reoffending for probation service users. However, the process of rapport building is not well documented in probation practice. This study conducted focus groups and interviews with London-based probation practitioners to understand their views of rapport when supervising service users. Thematic analysis generated five themes related to how practitioners facilitated rapport building and maintenance, as well as several barriers that exist towards building and maintaining rapport – these were conceptualised as a rapport-building process. We provide recommendations to help alleviate barriers and further facilitate the rapport-building process

Magnetic Phase Diagram of Ca2-xSrxRuO4 Governed by Structural Distortions

We constructed, by the first-principles calculations, a magnetic phase diagram of Sr$_{2}$RuO$_4$ in the space spanned by structural distortions. Our phase diagram can qualitatively explain the experimental one for Ca$_{2-x}$Sr$_x$RuO$_4$. We found that the rotation and the tilting of RuO$_6$ octahedron are responsible for the ferro- and antiferro-magnetism, respectively, while the flattening of RuO$_6$ is the key factor to stabilize those magnetic ground states. Our results imply that the magnetic and the structural instabilities in Sr$_2$RuO$_4$ are closely correlated cooperatively rather than competitively.Comment: 3 figures; accepted by PRB as rapid communicatio

Cartan Pairs

A new notion of Cartan pairs as a substitute of notion of vector fields in noncommutative geometry is proposed. The correspondence between Cartan pairs and differential calculi is established.Comment: 7 pages in LaTeX, to be published in Czechoslovak Journal of Physics, presented at the 5th Colloquium on Quantum Groups and Integrable Systems, Prague, June 199

Upper critical field in layered superconductors

The theoretical statements about a restoration of a superconductivity at magnetic fields higher than the quasiclassical upper critical field and a reentrance of superconductivity at temperatures $T_c(H)\approx T_c(0)$ in the superconductors with open Fermi surfaces are reinvestigated taking into account a scattering of quasiparticles on the impurities. The system of integral equations for determination of the upper critical field parallel to the conducting planes in a layered conventional and unconventional superconductors with impurities are derived. The $H_{c2}(T)$ values for the "clean" case in the Ginzburg-Landau regime and at any temperature in the "dirty" case are found analytically. The upper limit of the superconductor purity when the upper critical field definately has a finite value is established.Comment: 10 page

Fermi Surface, Surface States, and Surface Reconstruction in Sr2RuO4

The electronic structure of Sr2RuO4 is investigated by high angular resolution ARPES at several incident photon energies. We address the controversial issues of the Fermi surface (FS) topology and of the van Hove singularity at the M point, showing that a surface state and the replica of the primary FS due to (sqrt2 x sqrt2) surface reconstruction are responsible for previous conflicting interpretations. The FS thus determined by ARPES is consistent with the de Haas-van Alphen results, and it provides additional information on the detailed shape of the alpha, beta and gamma sheets.Comment: Final version for Physical Review Letters.

Expression of Keratinocyte Growth Factor in Periapical Lesions

The epithelial proliferation associated with inflammatory periapical lesions and with periapical cyst formation represents an interesting but poorly understood pathological change. Keratinocyte growth factor (KGF) is a recently identified growth factor that is produced by stromal fibroblasts and acts specifically to stimulate epithelial growth and differentiation. To investigate its possible role in the activation of the normally quiescent rests of Malassez, we examined the expression of KGF by in situ hybridization of sections of normal periodontal ligament (PDL) and of 12 periapical granulomas or cysts. Normal PDL and periapical granulomas with scant inflammatory infiltration showed few cells expressing message for KGF. However, KGFexpressing cells were found in the connective tissue stroma close to dense foci of inflammatory cells and to proliferating epithelial elements and cystic epithelial linings. Examination of tissues by the reverse-transcription polymerase chain reaction (RT-PCR) showed KGF expression in 4 specimens of periapical lesions but low or undetectable levels in normal PDL. These observations suggest that the induction of KGF expression in the stromal cells of periapical lesions may play an important role in stimulating the epithelial proliferation associated with cyst formation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66683/2/10.1177_00220345960750090701.pd
