Rebuilding Fiscal Institutions in Post-Conflict Countries

This paper reviews the key challenges in rebuilding fiscal institutions in post-conflict countries. Based on IMF technical assistance advice, it proposes a three-step framework for the creation or re-establishment of well-functioning public finance institutions: (i) creating a proper legal framework for fiscal management, (ii) establishing a central fiscal authority, and (iii) designing appropriate tax policies while simultaneously creating simple tax administration and expenditure management arrangements.post-conflict, fiscal instutions, public expenditure management, tax administration

Postconflict Countries: Strategy for Rebuilding Fiscal Institutions

This paper reviews the challenges and experiences in rebuilding fiscal institutions in postconflict environments, based on advice from the IMF's Fiscal Affairs Department to selected countries. The recommended strategy involved a three-step process of (i) creating a proper legal framework for fiscal management, (ii) establishing a central fiscal authority and a mechanism for co-ordinating foreign assistance, and (iii) designing appropriate tax policies while simultaneously creating simple tax administration and expenditure management arrangements. The advice was tailored to the circumstances of postconflict countries, and in some cases involved transitional measures that were not first best from an efficiency standpoint. In a similar vein, recommendations on revenue administration and expenditure management focused on the most basic tasks and procedures. In providing advice, care was taken to ensure that these measures were consistent with the eventual transformation to a modern fiscal management system.fiscal policy, tax, institutions, conflict

A micromechanics-inspired constitutive model for shape-memory alloys that accounts for initiation and saturation of phase transformation

A constitutive model to describe macroscopic elastic and transformation behaviors of polycrystalline shape-memory alloys is formulated using an internal variable thermodynamic framework. In a departure from prior phenomenological models, the proposed model treats initiation, growth kinetics, and saturation of transformation distinctly, consistent with physics revealed by recent multi-scale experiments and theoretical studies. Specifically, the proposed approach captures the macroscopic manifestations of three micromechanial facts, even though microstructures are not explicitly modeled: (1) Individual grains with favorable orientations and stresses for transformation are the first to nucleate martensite, and the local nucleation strain is relatively large. (2) Then, transformation interfaces propagate according to growth kinetics to traverse networks of grains, while previously formed martensite may reorient. (3) Ultimately, transformation saturates prior to 100% completion as some unfavorably-oriented grains do not transform; thus the total transformation strain of a polycrystal is modest relative to the initial, local nucleation strain. The proposed formulation also accounts for tension–compression asymmetry, processing anisotropy, and the distinction between stress-induced and temperature-induced transformations. Consequently, the model describes thermoelastic responses of shape-memory alloys subject to complex, multi-axial thermo-mechanical loadings. These abilities are demonstrated through detailed comparisons of simulations with experiments

Criticality in a Hadron Resonance Gas model with the van der Waals interaction

The van der Waals interaction is implemented in a Hadron Resonance Gas model. It is shown that this model can describe Lattice QCD data of different thermodynamical quantities satisfactorily with the van der Waals parameters $a = 1250 \pm 150$ MeV fm$^3$ and $r = 0.7 \pm 0.05$ fm. Further, a phase transition is observed in this model with the critical point at temperature, $T = 62.1$ MeV and baryon chemical potential, $\mu_B = 708$ MeV

The effect of exercise on behavioural and psychological symptoms of dementia: the EVIDEM-E randomised controlled clinical trial.

OBJECTIVE: The objective of this study is to evaluate the effectiveness of a simple dyadic (person with dementia and their main carer) exercise regimen as a therapy for the behavioural and psychological symptoms of dementia. METHOD: A two arm, pragmatic, randomised, controlled, single-blind, parallel-group trial of a dyadic exercise regimen (individually tailored walking regimen designed to become progressively intensive and last between 20-30 min, at least five times per week).Community-dwelling individuals with ICD-10 confirmed dementia with the following: clinically significant behavioural and psychological symptoms, a carer willing and able to co-participate in the exercise regimen, and no physical conditions or symptoms that would preclude exercise participation were invited by mental health or primary care services into the study. RESULTS: One hundred and thirty-one dyads were recruited to this study. There was no significant difference in Behavioural and Psychological Symptoms as measured by the Neuropsychiatric Inventory at week 12 between the group receiving the dyadic exercise regimen and those that did not (adjusted difference in means (intervention minus control) = -1.53, p = 0.6, 95% CI [-7.37, 4.32]). There was a significant between-group difference in caregiver's burden as measured by the Zarit Caregiver Burden Inventory at week 12 (OR = 0.18, p = 0.01, CI [0.05, 0.69]) favouring the exercise group. CONCLUSIONS: This study found that regular simple exercise does not appear to improve the behavioural and psychological symptoms of dementia, but did seem to attenuate caregiver burden. Further study to improve exercise uptake are needed

Z(N) wall junctions: Monopole fossils in hot QCD

We point out that the effective action of hot Yang--Mills theories has semi-classical solutions, which are naturally identified with monopole world lines, ``frozen'' into the short imaginary time dimension. The solutions look like wall junctions: lines along which N electric Z(N) domain walls come together. They are instrumental in reconciling explicit perturbative calculations at high temperature with the magnetic Z(N) symmetry.Comment: 10 pages, Late

Impact of a United Kingdom-wide campaign to tackle antimicrobial resistance on self-reported knowledge and behaviour change

BackgroundAs part of the 2014 European Antibiotic Awareness Day plans, a new campaign called Antibiotic Guardian (AG) was launched in the United Kingdom, including an online pledge system to increase commitment from healthcare professionals and members of the public to reduce antimicrobial resistance (AMR). The aim of this evaluation was to determine the impact of the campaign on self-reported knowledge and behaviour around AMR.MethodsAn online survey was sent to 9016 Antibiotic Guardians (AGs) to assess changes in self-reported knowledge and behaviour (outcomes) following the campaign. Logistic regression models, adjusted for variables including age, sex and pledge group (pledging as member of public or as healthcare professional), were used to estimate associations between outcomes and AG characteristics.Results2478 AGs responded to the survey (27.5% response rate) of whom 1696 (68.4%)pledged as healthcare professionals and 782 (31.6%) as members of public (similar proportions to the total number of AGs). 96.3% of all AGs who responded had prior knowledge of AMR. 73.5% of participants were female and participants were most commonly between 45-54 years old. Two thirds (63.4%) of participants reported always acting according to their pledge. Members of the public were more likely to act in line with their pledge than professionals (Odds Ratio (OR) =3.60, 95% Confidence Interval (CI): 2.88-4.51). Approximately half of participants (44.5%) (both healthcare professionals and members of public) reported that they acquired more knowledge about AMR postcampaign.People that were confused about AMR prior to the campaign acquired moreknowledge after the campaign (OR=3.10, 95% CI: 1.36-7.09). More participantsreported a sense of personal responsibility towards tackling AMR post-campaign, increasing from 58.3% of participants pre-campaign to 70.5% post-campaign.ConclusionThis study demonstrated that the campaign increased commitment to tackling AMR in both healthcare professional and member of the public, increased self-reported knowledge and changed self-reported behaviour particularly among people with prior AMR awareness. Online pledge schemes can be an effective and inexpensive way to engage people with the problem of AMR especially among those with prior awareness of the topic
