Combining carvacrol and nisin in biodegradable films for antibacterial packaging applications
2021
Abstract In this work, the feasibility of antibacterial biopolymeric films containing carvacrol (CRV) and a nisin commercial formulation (Nis) for potential food packaging applications was investigated. As polymer matrix, a commercial biodegradable polymer formulation of Mater-Bi (MB) was chosen due to its significant food packaging applications. CRV and Nis were chosen due to their well-established antibacterial properties and their potential synergistic effect. MB/CRV, MB/Nis, and MB/CRV/Nis systems were produced by melt mixing and compression molding. The mechanical properties of the films were evaluated by tensile tests. Differential scanning calorimetry was assessed aiming at investiga…
Secular Mean Reversion and Long-Run Predictability of the Stock Market
2013
Empirical financial literature documents the evidence of mean reversion in stock prices and the absence of out-of-sample return predictability over periods shorter than 10 years. The goal of this paper is to test the random walk hypothesis in stock prices and return predictability over periods longer than 10 years. Specifically, using 141 years of data, this paper begins by performing formal tests of the random walk hypothesis in the prices of the real S&P Composite Index over increasing time horizons up to 40 years. Even though our results cannot support the conventional wisdom which says that the stock market is safer for long-term investors, our findings speak in favor of the mean revers…
The Monitoring and Advisory Functions of Corporate Boards
2018
The main objective of this chapter is to investigate the effects of advisory directors’ presence on the board’s overall effectiveness in value creation. To achieve this purpose, we first explore the channels through which this advisory measure influences firm value. Thus, the results suggest that the presence of at least one independent director principally committed to advising duties on the board leads to an increase in corporate innovation and a better acquisition performance. We then examine the effect of this measure on firm value. Our findings highlight that the presence of advisory directors on the board is associated with a significant increase in firm value, especially for highly i…
Access to eHealth language-based services for multinational patients
2015
In more and more countries the number of citizens with double nationality is growing substantially. In their developing stage, current eHealth technologies are oriented towards helping the native patients rather than those speaking a foreign language that limits an access to the medical care. Nowadays, most people search the web for the medical symptoms of their disorders before going to the General Practitioner (GP), however multinational patients have limited chance to access eHealth care services not only owning to the lack of medical knowledge, but specifically due to their language barriers. In this study we investigate eHealth services on multilingual information access and online com…

Association of Maternal Secretor Status and Human Milk Oligosaccharides With Milk Microbiota: An Observational Pilot Study
2019
Background and Objectives: Breast milk contains several bioactive factors including oligosaccharides (HMO) and microbes that shape the infant gut microbiota. HMO profile is determined by secretor status, however their influence on milk microbiota is still uncovered. This study is aimed to determine the impact of the FUT2 genotype on the milk microbiota during the first month of lactation and the association with HMO. Methods: Milk microbiota from 25 healthy lactating women was determined by quantitative PCR and 16S gene pyrosequencing. Secretor genotype was obtained by PCR-RFLPs and by HMO identification and quantification. Results: The most abundant bacteria were Staphylococcus and Strepto…
Coordination of Wage Bargaining, Exchange Rate Stability and External Adjustment
2016
The literature on the determinants of the rate of current account reversion has been limited to examining the role of exchange rate regimes. We propose that the degree of coordination of wage bargaining affects the speed of current account adjustment. Our point estimates are economically and statistically significant, suggesting that fragmented firm-level wage bargaining facilitates external adjustment. We also find a strong negative interaction between the effects of coordination of wage bargaining and exchange rate stability on the rate of current account reversion.
Participation Costs for Responders Can Reduce Rejection Rates in Ultimatum Bargaining
2008
This paper reports data from an ultimatum mini-game in which responders first had to choose whether or not to participate. Participation was costly, but the participation cost was smaller than the minimum payoff that a responder could guarantee himself in the ultimatum game. Compared to a standard treatment, we find that the rejection rate of unfavorable offers is significantly reduced when participation is costly. A possible explanation based on cognitive dissonance is offered.
Does it (re)pay to be female? Considering gender in microfinance loan officer-client pairs
2021
This paper examines the effect of the gender combination of client-loan officer pairs on loan repayment in an Ecuadorian microfinance institution. We show that among the four possible client-loan officer gender pairs i.e. female client-female loan officer, female client-male loan officer, male client-male loan officer and male client-female loan officer, the most favourable pairs in terms of repayment are those with female loan officers whereas the least favourable are those with male loan officers. We also show that repayment is even further enhanced for all client-loan officer pairs when the client’s previous loan officer was a woman. Our findings point to relational differences between m…
