Failure and impact behavior of facade panels made of glass fiber reinforced cement(GRC)

GRC is a cementitious composite material made up of a cement mortar matrix and chopped glass fibers. Due to its outstanding mechanical properties, GRC has been widely used to produce cladding panels and some civil engineering elements. Impact failure of cladding panels made of GRC may occur during production if some tool falls onto the panel, due to stone or other objects impacting at low velocities or caused by debris projected after a blast. Impact failure of a front panel of a building may have not only an important economic value but also human lives may be at risk if broken pieces of the panel fall from the building to the pavement. Therefore, knowing GRC impact strength is necessary to prevent economic costs and putting human lives at risk. One-stage light gas gun is an impact test machine capable of testing different materials subjected to impact loads. An experimental program was carried out, testing GRC samples of five different formulations, commonly used in building industry. Steel spheres were shot at different velocities on square GRC samples. The residual velocity of the projectiles was obtained both using a high speed camera with multiframe exposure and measuring the projectile’s penetration depth in molding clay blocks. Tests were performed on young and artificially aged GRC samples to compare GRC’s behavior when subjected to high strain rates. Numerical simulations using a hydrocode were made to analyze which parameters are most important during an impact event. GRC impact strength was obtained from test results. Also, GRC’s embrittlement, caused by GRC aging, has no influence on GRC impact behavior due to the small size of the projectile. Also, glass fibers used in GRC production only maintain GRC panels’ integrity but have no influence on GRC’s impact strength. Numerical models have reproduced accurately impact tests.

Justice, emotions and satisfaction in complaint behavior in services

This study proposes a marketing approach to service recovery (SR) models in order to help to explain what factors affect cumulative satisfaction, loyalty and word-of-mouth following complaint behavior. The model has its base on the definition of perceived justice and its influence on satisfaction with service recovery (SSR) and on emotions (positive and negative). Trust acts as a central construct in the model, receiving influence from the affective and cognitive aspect and mediating the relationship between SSR and cumulative satisfaction and between positive/negative emotions and loyalty. The sample for this study consists of 303 Spanish B2C-EC users who made a complaint after an electronic transaction. Results from the analysis show the influence of perceived justice ?mainly interactional justice and procedural justice? on SSR, and the relevance of positive emotions as a key factor in SSR processes, in contrast to the major role which negative emotions have traditionally played in these models. Furthermore, trust mediates the relation between SSR and cumulative satisfaction, and is the factor which has a higher influence on loyalty, whilst cumulative satisfaction becomes the more relevant factor affecting WOM.

Mobility and Aging in Denver, Colorado: Travel Behavior, Mobility Barriers, and Perceptions of Transit

The number of seniors in the U.S. today is growing rapidly because of longer life expectancies and the aging Baby Boomer generation. This age groups' travel behavior will have substantial impacts on transportation, economics, safety, and the environment. This research used a mixed-methods approach to address issues of mobility and aging in Denver, Colorado. A quantitative approach was used to answer broad questions about travel behavior and the effects of age, gender, work status, disability, residential location and socio-economic status on mobility. Qualitative interviews with seniors in the Denver metro area were conducted to identify barriers to mobility, decision-making processes and travel decisions, and seniors' perceptions of public transit. The results of the quantitative and qualitative analyses show that residential location is an important variable for determining seniors' travel behaviors and transportation options. Perceptions of public transit were positive, but accessibility and information barriers exist that prevent older adult from using transit. The findings of this study will help to provide transportation and service recommendations to policymakers and planners in the Denver area as well as to inform studies of other North American cities with large aging populations.

The Impact of Spain’s Economic and Political Crisis on the European Elections. EPIN Commentaries No. 17, 2 April 2014

Despite the emergence of a critical debate against the EU-imposed austerity measures both at the level of the political elites and on the street, this EPIN Commentary by two Spanish political scientists based in Barcelona finds no sign that the upcoming European elections will have a more European focus than any of the previous ones. While there is no anti-European discourse among the Spanish mainstream political parties, they report that public trust in the European institutions is plummeting and Spanish turnout in European elections has been dropping in the last few years. In the authors’ view, the main reason for this is the low level of awareness of the functioning of the European Parliament but some responsibility also lies with the Spanish political parties and the way they deal with the electoral campaign to mobilise the discontented voters, who consider unemployment and the economic situation as the two most important issues that the country is facing at the moment.

Does All Fit One Size? An evaluation of the ECB policy response to changing economic conditions in the Euro area member states. ACES Cases No. 2008.1

This paper empirically investigates the extent to which the European Central Bank has responded to evolving economic conditions in its member states as opposed to the euro area as a whole. Based on a forward-looking Taylor rule-type policy reaction function, we conduct counterfactual exercises that compare the monetary policy behavior of the ECB with two alternative hypothetical scenarios: (1) were the euro member states to make individual policy decisions, and (2) were the ECB to respond to the economic conditions of individual members. The results reflect the extent of heterogeneity among the national economies in the monetary union and indicate that the ECB's monetary policy rates have been particularly close to the "counterfactual" interest rates of its largest euro members, as well as of countries with similar economic conditions, which includes Germany, Austria, Belgium and France.

Brexit – potential economic consequences if the UK exits the EU. Policy Brief #2015/05

If the United Kingdom (UK) exits the EU in 2018, it would reduce that country’s exports and make imports more ex-pensive. Depending on the extent of trade policy isolation, the UK’s real gross domestic product (GDP) per capita would be between 0.6 and 3.0 percent lower in the year 2030 than if the country remained in the EU. If we take into ac-count the dynamic effects that economic integration has on investment and innovation behavior, the GDP losses could rise to 14 percent. In addition, it will bring unforeseeable political disadvantages for the EU – so from our perspective, we must avoid a Brexit.

The economic voter and economic crisis

Theories of economic voting have a long tradition in political science and continue to inspire a large group of scholars. Classical economic voting theory assumes a reward-and-punishment mechanism (Key, 1966). This mechanism implies that incumbents are more likely to stay in power under a good economy, but are cast out under a bad economy (Lewis-Beck and Stegmaier, 2000). The economy has repeatedly been shown to be a major determinant of electoral behavior (see especially the recent book by Duch and Stevenson, 2008), but the current economic crisis seems to provide a marked illustration of how the economy affects voting. In recent elections across the Western industrialized world, most ruling coalitions lost their majority. Opposition parties, on the other hand, whether right wing or left wing, have appeared to benefit from the economic downturn.

An economic analysis of life expectancy by gender with application to the United States

This paper presents an economic model to explain the behavior of life expectancy of both sexes. It explicitly examines the relationship between the gender gap in life expectancy and the gender gap in pay. It shows that as the latter narrows over the course of economic development, the former may initially expand but will eventually shrink. Simulation results from our model accord with the behavior of life expectancy for both sexes since the 1940s in the United States. (C) 2003 Elsevier B.V. All rights reserved.
