Clusters of Traders in Financial Markets
2020
In this chapter we discuss Aoki’s work on the description of clusters of economic agents acting in a market. Specifically, we briefly discuss his work on the Ewens distribution and its application in a model of stock market with heterogeneous agents. We then review recent empirical analyses on the heterogeneity of financial market participants and make a working hypothesis for an empirical study on the distribution of the number of clusters of market participants in a real stock market monitored with a resolution down to the shadowed identity of market participants.
Improving the Representativeness of a Simple Random Sample: An Optimization Model and Its Application to the Continuous Sample of Working Lives
2020
This paper proposes an optimization model for selecting a larger subsample that improves the representativeness of a simple random sample previously obtained from a population larger than the population of interest. The problem formulation involves convex mixed-integer nonlinear programming (convex MINLP) and is, therefore, NP-hard. However, the solution is found by maximizing the size of the subsample taken from a stratified random sample with proportional allocation and restricting it to a p-value large enough to achieve a good fit to the population of interest using Pearson&rsquo
Non-participation modestly increased with distance to the examination clinic among adults in Finnish health examination surveys
2018
Aims: Health examination surveys (HES) provide important information about population health and health-related factors, but declining participation rates threaten the representativeness of collected data. It is hard to conduct national HESs at examination clinics near to every sampled individual. Thus, it is interesting to look into the possible association between the distance from home to the examination clinic and non-participation, and whether there is a certain distance after which the participation activity decreases considerably. Methods: Data from two national HESs conducted in Finland in 2011 and 2012 were used and a logistic regression model was fitted to investigate how distanc…
The collaborative outcomes study on health and functioning during infection times in adults (COH-FIT-Adults): Design and methods of an international …
2022
BACKGROUND: . High-quality comprehensive data on short-/long-term physical/mental health effects of the COVID-19 pandemic are needed. METHODS: . The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) is an international, multi-language (n=30) project involving >230 investigators from 49 countries/territories/regions, endorsed by national/international professional associations. COH-FIT is a multi-wave, on-line anonymous, cross-sectional survey [wave 1: 04/2020 until the end of the pandemic, 12 months waves 2/3 starting 6/24 months threreafter] for adults, adolescents (14-17), and children (6-13), utilizing non-probability/snowball and representative samp…
Capturing the Resilience of the Textile Companies as a Specific Response of the Fashion industry
2021
This chapter examines the most recent innovative activities of textile companies in Spain and their expansion into sanitary textiles and digitalization. In light of the global crisis caused by the COVID-19, we consider highly relevant to review the challenges of one of the most important fashion sectors, e.g., the textile industry, through this evolutionary period and the resilience of clusters. From this territorial perspective, we explained the industry’s restructuring and survival through three main elements: companies, relationships, and institutions. Companies are fundamental because they pave the way forward with their strategic responses. Relationships or clustering is the interactio…
Representative bureaucracy and seconded national government officials in the European Commission
2015
The bureaucratic arms of modern international organizations increasingly consist of staff with ambiguous organizational affiliations. This article analyses the implications of this trend from the perspective of representative bureaucracy – using seconded national experts (SNEs) in the European Commission (Commission) as the empirical laboratory. Using a variety of datasets, we unveil Commission SNEs' profiles (to assess their passive representativeness) and link these profiles to their role perceptions (to evaluate their potential for active representation). This illustrates that Commission SNEs' background characteristics do not match those of their constituent population (i.e. the EU27 po…
Las Cortes de 1443-1446 y la Hacienda de la villa de Alcoy

Las Cortes de 1428 y su repercusión en la Hacienda municipal de la ciudad de Valencia
2004
Call for Cortes council means to Valencia's city big expenses about municipal Treasury. All of them were accounted by <i>clavario</i> of the city in his book of accounts (document wages, copy, donations, etc.).
