A sustainable phenolic compound extraction system from olive oil mill wastewater
2017
Abstract The reduction of environmental impact and the achievement of economic advantages based on by-product recovery is the aim of applying methodologies for phenolic compounds extraction from Olive Oil Mill Wastewater. Volume reduction of Olive Oil Mill Wastewater could generate important advantages in terms of waste disposal cost abatement and, in addition, reuse in the production of foods with health properties could lead to economic benefits. Despite the fact that literature shows that several techniques have been developed, few economic approaches have been presented. This paper assesses the economic feasibility of a system based on membrane filtration and reverse osmosis processes f…
Corporate Governance Configurations and Corporate Social Responsibility Disclosure: Qualitative Comparative Analysis of Audit Committee and Board cha…
2020
[EN] Drawing on the complexity theory and responding to the recent calls to use such creative methods that mix between a quantitative and qualitative approach. Therefore, this study fills the literature gap, adding novelties, showing evidence from the unexplored (or underexplored) European context and, consequently, shedding light to inconclusive results in previous research concerning the effect of audit committee (AC) and board characteristics on corporate social responsibility (CSR) disclosure by applying a novel research methodology: the fuzzy set qualitative comparative analysis. The data were collected from Eikon database for a sample of the top 69 non¿financial European companies (ba…
Minding the Gaps : The Role of Finnish Civil Society Organizations in the Labour Market Integration of Migrants
2021
AbstractThe growing role of civil society organizations (CSOs) in welfare service provision is sometimes portrayed as a threat to welfare state universalism in Nordic societies. In Finland, CSOs co-produce integration services alongside comprehensive official integration programmes, compensating for gaps and shortcomings in those services. We identify three “gaps”, which are (1) limited availability of services in terms of time and target group, (2) lack of direct labour market contacts and (3) limited flexibility to serve individual needs. We assess how CSOs target these gaps with their service offerings through qualitative interviews with policy implementers, CSO workers and migrants. How…
Vocational bachelor graduates in France: labour market integration and social mobility
2014
Purpose – In France, the vocationalization of higher education has resulted in an increase in the number of graduates and created new opportunities. The access of these vocational bachelor graduates to the labour market raises the issue of their professional prospects amid changing economic and social circumstances. The paper aims to discuss these issues. Design/methodology/approach – To provide insights into these issues, the employment situation of bachelor graduates during the first years of active working life will be compared with other tertiary graduates entering the labour market in the same years, using econometric models that estimate the effects of vocational courses “all other t…
Environmental Sustainability Orientation, Reward-Based Crowdfunding, and Venture Capital: The Mediating Role of Crowdfunding Performance for New Tech…
2021
Extant literature has investigated the effects of new ventures’ environmental sustainability orientation (ESO) on the crowdfunding (CF) performance and on the ability to secure venture capital, separately and with mixed results. In this article, we address the study of these relationships simultaneously. Specifically, we examine how the presence of ESO features influences new technology-based ventures’ ability to secure funding in reward-based CF campaigns and how the CF performance mediates the effect of such features on attracting subsequent venture capital. Using a sample of new hardware ventures that have launched a CF campaign on Kickstarter, we document a negative effect of the presen…
An empirical investigation into market risk disclosure: is there room to improve for Italian banks?
2020
PurposeThis paper aims to examine the market risk disclosure practices of large Italian banks. The contribution provides insights on the way banks should provide information about market risk. The problem related to the asymmetric information between banks from one side, and investors and stakeholders on the other, represents a crucial issue that requires further considerations by scholars and regulators.Design/methodology/approachThis contribution adopts a mixed methodological approach to analyse both qualitative and quantitative profiles of market risk disclosure in banking. This paper analyses the most important documents Italian banks are required to prepare for risk disclosure purposes…
Market valuation and acquiring firm performance in the short and long term: Out-of-sample evidence from Spain
2019
We investigate bidder’s short- and long-term performance in periods of high and low valuation market in response to announcements of acquisitions carried out by Spanish listed firms over the period 1991–2016. We find that acquirers of unlisted targets fully react at the announcement date in high valuation periods, meanwhile the underreaction of listed target bidders at the moment of the announcement in low valuation markets is the result of return continuations. In addition, we find that the market reaction do not depend on recent merger history. Therefore, we provide evidence that bidder reaction to acquisitions is not consistent with the predictions of market sentiment (optimism) after c…
A GRASP algorithm for constrained two-dimensional non-guillotine cutting problems
2005
This paper presents a greedy randomized adaptive search procedure (GRASP) for the constrained two-dimensional non-guillotine cutting problem, the problem of cutting the rectangular pieces from a large rectangle so as to maximize the value of the pieces cut. We investigate several strategies for the constructive and improvement phases and several choices for critical search parameters. We perform extensive computational experiments with well-known instances previously reported, first to select the best alternatives and then to compare the efficiency of our algorithm with other procedures.
Bayesian forecasting with the Holt–Winters model
2010
Exponential smoothing methods are widely used as forecasting techniques in inventory systems and business planning, where reliable prediction intervals are also required for a large number of series. This paper describes a Bayesian forecasting approach based on the Holt–Winters model, which allows obtaining accurate prediction intervals. We show how to build them incorporating the uncertainty due to the smoothing unknowns using a linear heteroscedastic model. That linear formulation simplifies obtaining the posterior distribution on the unknowns; a random sample from such posterior, which is not analytical, is provided using an acceptance sampling procedure and a Monte Carlo approach gives …
Tabu search for a multi-objective routing problem
2006
Multi-objective optimization problems deal with the presence of different conflicting objectives. Given that it is not possible to obtain a single solution by optimizing all the objectives simultaneously, a common way to face these problems is to obtain a set of efficient solutions called the non-dominated frontier. In this paper, we address the problem of routing school buses with two objectives: minimize the number of buses, and minimize the longest time a student would have to stay in the bus. The trade-off in this problem is between service level, which is represented by the maximum route length, and operational cost, which is represented by the number of buses in the solution. We prese…
