TL;DR: In this article, the authors explore the role of price or quantity leadership in facilitating collusion, and show that price leadership facilitates collusion by making it easier to punish deviations by the leader.

TL;DR: In this article, a tutorial on formal concept analysis (FCA) and its applications is presented, which is an applied branch of Lattice theory, a mathematical discipline which enables formalisation of concepts as basic units of human thinking and analysing data in the object-attribute form.
Abstract: This paper is a tutorial on Formal Concept Analysis (FCA) and its applications. FCA is an applied branch of Lattice Theory, a mathematical discipline which enables formalisation of concepts as basic units of human thinking and analysing data in the object-attribute form. Originated in early 80s, during the last three decades, it became a popular human-centred tool for knowledge representation and data analysis with numerous applications. Since the tutorial was specially prepared for RuSSIR 2014, the covered FCA topics include Information Retrieval with a focus on visualisation aspects, Machine Learning, Data Mining and Knowledge Discovery, Text Mining and several others.

TL;DR: It is shown that the regret, as well as the rate of sampling from the inferior population, can be finite or grow at various rates with the time horizon of the problem, depending on "local" properties of the covariate distribution.
Abstract: We consider the one-armed bandit problem of Woodroofe [J. Amer. Statist. Assoc. 74 (1979) 799-806], which involves sequential sampling from two populations: one whose characteristics are known, and one which depends on an unknown parameter and incorporates a covariate. The goal is to maximize cumulative expected reward. We study this problem in a minimax setting, and develop rate-optimal polices that involve suitable modifications of the myopic rule. It is shown that the regret, as well as the rate of sampling from the inferior population, can be finite or grow at various rates with the time horizon of the problem, depending on "local" properties of the covariate distribution. Proofs rely on martingale methods and information theoretic arguments.

TL;DR: In this paper, the authors look at the subjective evaluations of a number of coping strategies that respondents undertook to mitigate the effect on their welfare of the Russian financial crisis and find that households with low human capital, households headed by pensioners, and low-educated households are more likely to be socially excluded.
Abstract: The paper looks at the subjective evaluations of a number of coping strategies that respondents undertook to mitigate the effect on their welfare of the Russian financial crisis. Given the dramatic drop in formal cash incomes, how are people able to adapt? What are the relative importance and effectiveness of coping strategies to resist hardship in reducing poverty for different groups of households? The results of the analysis indicate that the choices of survival strategies are determined by the level of human capital in the household. The higher the household human capital, the more likely the household is to choose active strategies. Households with low human capital, households headed by pensioners, and low-educated households are more likely to be socially excluded. A specific set of policy interventions should be targeted on such households to avoid the entrenchment of poverty, and the trend toward marginalization and impoverishment of these groups should be expressly monitored.

TL;DR: In this article, the authors used an external magnetic field to probe the detection mechanism of a superconducting nanowire single-photon detector and found that the hot belt model does not explain observed weak-field dependence of the photon count rate.
Abstract: We use an external magnetic field to probe the detection mechanism of a superconducting nanowire single-photon detector We argue that the hot belt model (which assumes partial suppression of the superconducting order parameter $\mathrm{\ensuremath{\Delta}}$ across the whole width of the superconducting nanowire after absorption of the photon) does not explain observed weak-field dependence of the photon count rate (PCR) for photons with $\ensuremath{\lambda}=450\phantom{\rule{4pt}{0ex}}\mathrm{nm}$ and noticeable decrease of PCR (with increasing the magnetic field) in a range of the currents for photons with wavelengths $\ensuremath{\lambda}=450--1200\phantom{\rule{4pt}{0ex}}\mathrm{nm}$ Found experimental results for all studied wavelengths can be explained by the vortex hot spot model (which assumes partial suppression of $\mathrm{\ensuremath{\Delta}}$ in the area with size smaller than the width of the nanowire) if one takes into account nucleation and entrance of the vortices to the photon induced hot spot and their pinning by the hot spot with relatively large size and strongly suppressed $\mathrm{\ensuremath{\Delta}}$
