Numerous materials are essentially structures of discrete fibres, yarns or struts. Considering these materials at their discrete scale, one may distinguish two types of intrinsic randomness that affect the structural behaviours of these discrete structures: geometrical randomness and material randomness. Identifying the material randomness is an experimentally demanding task, because many small fibres, yarns or struts need to be tested, which are not easy to handle. To avoid the testing of hundreds of constituents, this contribution proposes an identification approach that only requires a few dozen of constituents to be tested (we use twenty to be exact). The identification approach is applied to articially generated measurements, so that the identified values can be compared to the true values. Another question this contribution aims to answer is how precise the material randomness needs to be identified, if the geometrical randomness will also influence the macroscale behaviour of these discrete networks. We therefore also study the effect of the identified material randomness to that of the actual material randomness for three types of structures; each with an increasing level of geometrical randomness.

This article investigates the impact of remittances on credit in 30 developing (low and middle income) countries and 27 developed (high-income) countries during the period of 2000-2014. This paper differs from existing literature in two ways. First, we distinguish the impact of remittances on credit in both the short run and the long run. Second, we investigate whether remittances influence credit provided to households and credit provided to firms differently, thanks to a new dataset. Our results indicate that (i) remittances have a positive impact on credit in the long run but no impact in the short run; (ii) remittances have a stronger effect on household credit than on firm credit in developing countries; and, (iii) remittances stimulate credit provision through firm credit in developed countries.

This paper investigates whether long-term finance affects firm entry worldwide. We construct a new database on short-term and long-term credit provided by commercial banks to the private sector in 85 countries over the period 1995-2014. We then analyze whether differences in entrepreneurship are related to the provision of short-term and long-term bank credit. Data on entrepreneurship are extracted from two frequently used databases: the Global Entrepreneurship Monitoring dataset and the Entrepreneurship Database, each of which captures different aspects of firm creation. Econometric results indicate that long-term credit does not stimulate firm entry. By contrast, we find that short-term credit is positively related to firm creation, from birth to registration. Controlling for potential endogeneity by implementing an instrumental variables approach does not affect our conclusions. Our findings suggest that better provision of short-term credit allows entrepreneurs to apply for formal loan instead of having to rely exclusively on informal loans or internal funds. The absence of impact of long-term loans can be explained by the difficulty entrepreneurs face in getting access to long-term credit. [less ▲]

We introduce the notion of almost commutative Q-algebras and demonstrate how the derived bracket formalism of Kosmann-Schwarzbach generalises to this setting. In particular, we construct ‘almost commutative Lie algebroids’ following Vaintrob’s Q-manifold understanding of classical Lie algebroids. We show that the basic tenets of the theory of Lie algebroids carry over verbatim to the almost commutative world. [less ▲]

This paper studies experimentally the behaviour of circular FRP-steel-confined columns subjected to reversed cyclic loads. The influence of main structural factors on the cyclic behaviour of the columns is discussed. Test results show the outstanding seismic performance of FRP-steel confined reinforced concrete (RC) and steel-reinforced concrete (SRC) column. The lateral confinement effectiveness of FRP materials is verified in the steel tube confined RC columns. A simplified finite element method (FEM) model supported by OpenSees is developed to simulate the experimental results of the test columns. Based on the proposed FEM model, a parametric analysis is conducted for investigating the effects of several main factors on the reversed cyclic behaviour of GFRP-steel confined RC columns. Based on the test and numerical analyses, the study discusses the influence of variables such as the lateral confinement on the plastic hinge region and peak drift ratio of the studied concrete columns under reversed cyclic loads. Results indicate that the lateral confinement significantly affects the height of plastic hinge region of circular confined columns without H-steel. Based on the analysies of test data from the study and literature, the paper suggests a simple model to predict the peak drift ratio of the confined RC columns. [less ▲]

Brian Leiter (2016) throws down two gauntlets to philosophers engaged in dialogue with the broader public. If, with the first, public philosophers recognize that they cannot offer substantive answers but only sophisticated method, they nevertheless fail to realize that said method does not resonate with the very public whom they purport to help. For, with the second, that method does not engage the emotivist and tribalist cast of contemporary public discourse: emotivist because a person’s moral and political beliefs are a function of emotional attitudes or affective responses for which she adduces reasons post hoc; tribalist because the person tracks not the inferential relation between beliefs but her similarity with interlocutors. In order to understand the full extent of this critique, it is necessary, first, to parse strands of public philosophy, distinct discursive sites, and pictures of philosophical practice and, then, to probe the critique’s empirical groundedness and intended scope. These elements in place, it is then possible to sketch public philosophy reconceived along Leiter’s lines as equal part rigor and rhetoric. That sketch may be somewhat filled out through two tactics employed in Jeffrey Stout’s (2004, 2010) work. These form part of a toolkit for philosophical dialogue whereby philosophers get a discursive grip on non-discursive factors underlying public discourse and push back on Leiter's dilemma. [less ▲]

Conventional wisdom holds that building democracy takes time. Deliberative democracy will likely prove no exception. To that end, this chapter will explore one possible path towards more deliberative institutions and decision-making in the form of Gastil and Wright’s proposal for a Sortition Chamber. Our thesis is that deliberative innovations, notably a sortition chamber, require a gradualist approach to implementation. While other authors in this volume may take for granted that some form of sortition chamber will be institutionalized and focus instead on design questions, we probe the necessary conditions preceding institutionalization. To support this thesis, we shall make an argument comprising four main claims. 1.) Sortition is a promising deliberative innovation. 2.) A strong, unaccountable deliberative device like sortition may delegitimize citizen deliberation and future deliberative innovations, in particular a sortition chamber. 3.) A weaker deliberative device like citizens’ consultation is effective though often blocked by a lack of institutional footing. 4.) Citizens’ consultation, once proven to be effective and regular, opens one path towards enhanced deliberative innovations like the sortition chamber. Claim 1.) will not be developed here beyond the point that a sortition chamber’s “hybrid legitimacy” may allow it to overcome critiques addressed to one-shot, single-issue consultative or 1 empowered mini-publics which may lack institutional footing1. Such mini-publics face multiple challenges: significant social or political uptake, electoral accountability, capture by interests, political redundancy, representativeness, biases, frames2. If a sortition chamber prima facie meets or precludes these different critiques, it represents a striking contribution to democratic innovations beyond mini-publics. That said, we must work out claims 2.), 3.) and 4.) in individual sections below. While examples in 3.) and 4.) will mainly be drawn from the European Union, we maintain that this argument is broadly applicable at local, regional national and transnational levels. We argue that, if institutionalizing consultative mini-publics is desirable and feasible at the EU level, it will be all the more so at other levels throughout the decision-making process’ different stages.

This paper presents a methodology for comparing income rank volatility profiles over time and across distributions. While most of the existing measures are affected by changes in marginal distributions, this paper proposes a framework that is based on individuals’ relative positions in the distribution, and is neutral in relation to structural changes that occur in the economy. Applying this approach to investigate rank volatility in Germany and the US over three decades, we show that while poorer individuals within both countries are the most volatile, the volatility trend for the middle class in each of these countries differs.
