Analysis of the spawning stock-recruitment relationship of vendace (Coregonus albula (L.)) with evaluation of alternative models, additional variable…
2004
– Spawning biomass and recruitment data for vendace from a central Finnish lake were analysed by fitting various recruitment models and comparing the fits statistically. The compensatory models of Ricker, Cushing and Beverton & Holt fitted the data better than the H0 hypothesis of constant proportionality, but model and parameter uncertainties were high. Additional variables were included in an attempt to reduce uncertainties. Heavy wind forcing during the first month after hatching of larvae reduced the recruitment success. For the Ricker and the Cushing models, recruitment seemed to be also negatively associated with the density of the previous year-class. The r2 increased considerably w…
Multi-mycotoxin occurrence in feed, metabolism and carry-over to animal-derived food products: A review
2021
The world requests for raw materials used in animal feed has been steadily rising in the last years driven by higher demands for livestock production. Mycotoxins are frequent toxic metabolites present in these raw materials. The exposure of farm animals to mycotoxins could result in undesirable residues in animal-derived food products. Thus, the potential ingestion of edible animal products (milk, meat and fish) contaminated with mycotoxins constitutes a public health concern, since they enter the food chain and may cause adverse effects upon human health. The present review summarizes the state-of-the-art on the occurrence of mycotoxins in feed, their metabolism and carry-over into animal …

Spanish Stock Returns: Rational or Weather-Influenced?
2002
Psychological studies support the existence of an influence of weather on mood. It could affect the behaviour of market traders, as suggested by some authors, and this should be reflected by the stock returns. This paper investigates the possible relation between weather and market index returns in the context of the Spanish market, in order to test the above hypothesis. In 1989, this market changed its open outcry trading system into a computerised and decentralised trading system. Therefore, it is possible to check the influence of weather variables (sunshine hours and humidity levels) on index returns in an open outcry trading system, and to compare it with a screen traded environment. T…
Multidimensional scaling and stock location assignment in a warehouse: an application
1999
By means of an application, in the present paper, the suitability of a multivariate statistical methodology, as multidimensional scaling (MDS), to solve an optimization problem is shown. In particular, considering the stock location assignment problem in the warehouse of a supermarket chain, the solution gained by applying MDS to a set of seven variables is compared with the one obtainable by considering the usual techniques applied in this context. A wide discussion of results is reported. Copyright © 1999 John Wiley & Sons, Ltd.
El efecto del anuncio de beneficios cuando cotizan opciones: un estudio conjunto del mercado de contado y el mercado de opciones
2015
ResumenEl objetivo del trabajo es comprobar, para los mercados de valores españoles, si el comportamiento de los precios incorporando la información revelada por el anuncio de beneficios trimestrales, es más eficiente en aquellas empresas en las cuales se negocian opciones sobre sus acciones. Utilizando la tradicional metodología del suceso y la comparación de funciones de distribución, obtenemos que para las empresas con opciones, la información se incorpora antes. Además, verificamos que hay un comportamiento anormal en el mercado de opciones que viene explicado por la información que contiene el beneficio. Los resultados obtenidos soportan la mejora de la eficiencia del mercado de contad…
Effects of external imbalances on GDP recovery patterns
2021
Abstract A decade after the beginning of the Great Recession, flow external imbalances, measured by the current account (CA) have narrowed markedly. However, stock or net foreign assets (NFA) imbalances have kept increasing and have created challenges for future macroeconomic and financial stability. To date, early warning systems (scoreboards) have focused more on flow than on stock variables. To approach this problem, in this paper we analyze expansions using two complementary sets of indicators proposed by Harding and Pagan (2002) and Gadea et al. (2017) for the period 1950–2016. After controlling for a large set of explanatory variables, we find that the effect of CA imbalances is limit…
Categorizing and assessing multi-campus universities in contemporary higher education
2016
Multi-campus universities are not a new phenomenon per se, but they have become an increasing feature of contemporary higher education systems all over the world. In the case of Northern Europe, multi-campus universities are the consequence of contraction patterns resulting from overcapacity, fragmentation and rising competition. This paper has two main objectives. First, to take stock of the existing scientific literature on multi-campus universities and, on that basis, develop a novel conceptual framework for categorizing such systems, with focus on the level of autonomy and profile enjoyed by the individual campuses composing a given system or university. Second, we provide new empirical…
Sport as a vehicle for implementing corporate social responsibility: firms listed on the Warsaw and Moscow stock exchanges
2021
This paper provides a descriptive account of the extent to which firms listed on the Warsaw (WSE) and Moscow (MSE) Stock Exchanges use sport for their corporate social responsibility agendas. Drawing on institutional isomorphism, we deductively categorised CSR through sport cases based on the framework developed by Bason and Anagnostopoulos (2015). A total of 1317 documents were content-analysed, 442 from WSE firms and 875 from MSE firms. A total of 2501 CSR-through-sport initiatives were reported over the five-year period studied (2013-2017) in the WSE case and 2175 in the MSE case. Our results show that internationally listed firms are increasingly embracing sport for their CSR programs, …
Effects of PET packaging on the quality of an orange juice made from concentrate
2004
An orange juice made from concentrate was conditioned in three different PET (PolyEthylene Terephtalate) and glass packagings. Influence of storage conditions (length of storage, light, oxygen) on vitamin C content, browning index, and colour were measured. Results show that permeability to oxygen of PET packagings is the major factor detrimentally affecting the above parameters.
