The fragility of two monetary regimes: The European Monetary System and the Eurozone. National Bank of Belgium Working Paper No. 243, October 2013

The purpose of these working papers is to promote the circulation of research results (Research Series) and analytical studies (Documents Series) made within the National Bank of Belgium or presented by external economists in seminars, conferences and conventions organised by the Bank. The aim is therefore to provide a platform for discussion. The opinions expressed are strictly those of the authors and do not necessarily reflect the views of the National Bank of Belgium.

ECB Policy and Eurozone Fragility: Was De Grauwe Right? CEPS Working Document No. 397, June 2014

Paul De Grauwe’s fragility hypothesis states that member countries of a monetary union such as the eurozone are highly vulnerable to a self-fulfilling mechanism by which the efforts of investors to avoid losses from default can end up triggering the very default they fear. The authors test this hypothesis by applying an eclectic methodology to a time window around Mario Draghi’s “whatever it takes” (to keep the eurozone on firm footing) pledge on 26 July 2012. This pledge was soon followed by the announcement of the Outright Monetary Transactions (OMT) programme (the prospective and conditional purchase by the European Central Bank of sovereign bonds of eurozone countries having difficulty issuing debt). The principal components of eurozone credit default swap spreads validate this choice of time frame. An event study reveals significant pre announcement contagion emanating from Spain to Italy, Belgium, France and Austria. Furthermore, time-series regression confirms frequent clusters of large shocks affecting the credit default swap spreads of the four eurozone countries but solely during the pre-announcement period. The findings of this report support the fragility hypothesis for the eurozone and endorse the Outright Monetary Transactions programme.

Glass fragility and atomic ordering on the intermediate and extended range

The relation between the fragility of glass-forming systems, a parameter which describes many of their key physical characteristics, and atomic scale structure is investigated by using neutron diffraction to measure the topological and chemical ordering for germania, or GeO2, which is an archetypal strong glass former. We find that the ordering for this and other tetrahedral network-forming glasses at distances greater than the nearest neighbor can be rationalized in terms of an interplay between the relative importance of two length scales. One of these is associated with an intermediate range, the other with an extended range and, with increasing glass fragility, it is the extended range ordering which dominates.

State fragility and international development co-operation

Over the past few years addressing state fragility in the third world has become an important priority in international development cooperation. However, it seems that the international donor community has so far not been able to develop adequate instruments for dealing with the problems posed by state failure. We see two reasons for this: (i) there is growing recognition within the donor community that the lack of absorptive capacity, or bad economic policies in the partner country can actually make aid counterproductive, even harmful; and (ii) it is very difficult to manage effective development cooperation with weak governments. Channelling aid through NGOs, or giving limited aid in the form of capacity-building is clearly not sufficient to solve the problems fragile states face.

Changes in Hematological Parameters and Erythrocyte Osmotic Fragility in Lame and Aged Horses Administered with Resveratrol Supplement

The study was aimed at evaluating the changes in haematological parameters and erythrocyte osmotic fragility in lame and aged horses administered with resveratrol supplement (Equithrive joint®). A total of 16 horses of both sexes, aged 18 ± 0.65 and showing lameness grade 3 were used for the study. The horses weighed 350-450 kg and comprised 8 horses which were administered with resveratrol supplement for 4 weeks and 8 others, which served as controls and given only Saccharomyces cerevisiae yeast strain used as carrier in the supplement. Blood samples were collected from each horse before supplementation and at weekly intervals for 4 weeks of the experiment. Haematological parameters and erythrocyte osmotic fragility were determined by standard methods. Equithrive joint® increased significantly (P ˂ 0.05) packed cell volume, haemoglobin concentration and erythrocyte counts in the treated horses while total leucocyte, neutrophil and eosinophil counts decreased significantly (P ˂ 0.05) in the treated horses compared with the untreated horses. Erythrocyte osmotic fragility test showed decreased haemolysis in the treated horses. The result indicated that equithrive joint® a potent antioxidant and anti-inflammatory agent maintained the membrane integrity of red blood cells and may be of value in aiding horses move with ease during ageing.

Age-Dependent Fragility and Life-Cycle Cost Analysis of Timber and Steel Distribution Poles Subjected to Hurricanes

Power distribution systems are susceptible to extreme damage from natural hazards especially hurricanes. Hurricane winds can knock down distribution poles thereby causing damage to the system and power outages which can result in millions of dollars in lost revenue and restoration costs. Timber has been the dominant material used to support overhead lines in distribution systems. Recently however, utility companies have been searching for a cost-effective alternative to timber poles due to environmental concerns, durability, high cost of maintenance and need for improved aesthetics. Steel has emerged as a viable alternative to timber due to its advantages such as relatively lower maintenance cost, light weight, consistent performance, and invulnerability to wood-pecker attacks. Both timber and steel poles are prone to deterioration over time due to decay in the timber and corrosion of the steel. This research proposes a framework for conducting fragility analysis of timber and steel poles subjected to hurricane winds considering deterioration of the poles over time. Monte Carlo simulation was used to develop the fragility curves considering uncertainties in strength, geometry and wind loads. A framework for life-cycle cost analysis is also proposed to compare the steel and timber poles. The results show that steel poles can have superior reliability and lower life-cycle cost compared to timber poles, which makes them suitable substitutes.

Seismic fragility assessment of unreiforced masonry aggregate buildings

Aggregate masonry buildings have been generated over the years, allowing the interaction of different aggregated structural units under seismic action. The first part of this work is focused on the seismic vulnerability and fragility assessment of clay brick masonry buildings, sited in Bologna (Italy), with reference, at first, to single isolated structural units, by means of the Response Surface statistical method, taking into account some variabilities and uncertainties involved in the problem. The seismic action was defined by means of a group of selected registered accelerograms, in order to analyse the effect of the variability of the earthquakes. Identical and different structural units chosen by the Response Surface generated simulations are then aggregated in row, in order to compare the collapse PGA referred to the isolated structural unit and the one referred to the aggregate structure. The second part is focused on the seismic vulnerability and fragility assessment of stone masonry structures, sited in Seixal (Portugal), applying a methodology similar to that used for the buildings sited in Bologna. Since the availability of several information, the analyses involved the assessment of the most prevalent structural typologies in the area, considering the variability of a set of structural and geometrical parameters. The results highlighted the importance of the statistic procedures as method able to consider the variabilities and the uncertainties involved in the problem of the fragility of unreinforced masonry structures, in absence of accurate investigations on the structural typologies, as in the Seixal case study. Furthermore, it was showed that the structural units along the unreinforced clay brick or stone masonry aggregates cannot be analysed as isolated, as they are affected by the effect of the aggregation with adjacent structural units, according to the different directions of the seismic action considered and to their different position along the row aggregate.

[insomnia Symptoms, Daytime Naps And Physical Leisure Activities In The Elderly: Fibra Study Campinas].

The practice of physical activities contributes to reducing the risk of chronic diseases and improves sleep patterns in the elderly. This research aimed to investigate the association between insomnia symptoms and daytime nap and the participation in physical leisure activities in elderly community residents. Data from the Studies Network of the Fragility in Brazilian Elderly (Campinas site), were used. Information from 689 elderly was analyzed, regarding sociodemographic characterization, physical leisure activity, occurrence of daytime napping and its duration, symptoms of insomnia and use of sleep medication. A significant association was found between the practice of walking and the daytime nap of short duration. Studies indicate that a short nap can benefit the quality of sleep and health of the elderly. Therefore, promoting the practice of walking can be a nursing intervention that favors the sleep patterns of the elderly.
