‘A stitch in time…may save nine’: A systematic synthesis of the evidence for domestic violence management and prevention in Emergency Care

The aim of this policy brief is to provide an evidence-informed answer to the question: ‘What is the role and scope of pre-hospital emergency care providers to domestic violence (DV) intervention as a form of gender-based violence prevention?’ The answer is intended to determine the theoretical and clinical best practice to inform the emergency care community and policy development by critically appraising the evidence that considers the responsiveness of Emergency Medical Services to the health needs of DV victims. Evidence-informed Decision Making methods are employed. The evidence appraised was based on electronic searchesusing the Cape Peninsula University of Technology database. Research and non-research publications were considered with publication dates mostly from 1999 to 2011. Upon screening 164 articles for content relevance, 53 were critically appraised against predetermined criteria for relevance of the evidence, robust nature of the evidence and presence of bias. A thematic/narrative analysis ensued in terms of strength of evidence and frequency of findings. Early recognition and intervention is seen as one of the most effective methods of DV prevention. This finding is nuanced if it is male caregivers doing so. There is an ethical obligation to implement a comprehensive health approach to manage domestic violence victims. The strong, majority findings are that educational intervention/s increases the health care provider’s understanding of DV and improves screening for DV. The research supports the development and use of screening tools/guidelines/ procedures for DV as they are found to improve DV intervention. The evidence supports an integrated effort of the health system in achieving its goal of DV prevention by promoting the participation of pre-hospital emergency care providers as critical stakeholders.Key words: Domestic Violence (DV) management and prevention, Emergency Care Providers (ECP’s), Gender-based violence (GBV) prevention, Evidence-informed Decision Making (EiDM), Emergency Medical Servic

Analytical Bethe Ansatz for A2n−1(2),Bn(1),Cn(1),Dn(1)A^{(2)}_{2n-1}, B^{(1)}_n, C^{(1)}_n, D^{(1)}_n quantum-algebra-invariant open spin chains

We determine the eigenvalues of the transfer matrices for integrable open quantum spin chains which are associated with the affine Lie algebras $A^{(2)}_{2n-1}, B^{(1)}_n, C^{(1)}_n, D^{(1)}_n$, and which have the quantum-algebra invariance U_q(C_n), U_q(B_n), U_q(C_n), U_q(D_n)$, respectively.Comment: 14 pages, latex, no figures (a character causing latex problem is removed

Quantum Group Invariant Supersymmetric t-J Model with periodic boundary conditions

An integrable version of the supersymmetric t-J model which is quantum group invariant as well as periodic is introduced and analysed in detail. The model is solved through the algebraic nested Bethe ansatz method.Comment: 11 pages, LaTe

On the algebraic Bethe ansatz: Periodic boundary conditions

In this paper, the algebraic Bethe ansatz with periodic boundary conditions is used to investigate trigonometric vertex models associated with the fundamental representations of the non-exceptional Lie algebras. This formulation allow us to present explicit expressions for the eigenvectors and eigenvalues of the respective transfer matrices.Comment: 36 pages, LaTex, Minor Revisio

Quantum spin chain with "soliton non-preserving" boundary conditions

We consider the case of an integrable quantum spin chain with "soliton non-peserving" boundary conditions. This is the first time that such boundary conditions have been considered in the spin chain framework. We construct the transfer matrix of the model, we study its symmetry and we find explicit expressions for its eigenvalues. Moreover, we derive a new set of Bethe ansatz equations by means of the analytical Bethe ansatz method.Comment: 12 pages, LaTeX, two appendices added, minor correction

Classification of reflection matrices related to (super) Yangians and application to open spin chain models

We present a classification of diagonal, antidiagonal and mixed reflection matrices related to Yangian and super-Yangian R matrices associated to the infinite series so(m), sp(n) and osp(m|n). We formulate the analytical Bethe Ansatz resolution for the so(m) and sp(n) open spin chains with boundary conditions described by the diagonal solutions.Comment: 36 pages ; references added ; typos corrected, precisions adde
