Experimental data from flesh quality assessment and shelf life monitoring of high pressure processed European sea bass (Dicentrarchus labrax) fillets

Fresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation and leads to waste, which has a negative impact on aquaculture sustainability. New non-thermal food processing methods, such as high pressure (HP) processing, prolong shelf-life while assuring high food quality. The effect of HP processing (600MPa, 25 °C, 5min) on European sea bass (Dicentrarchus labrax) fillet quality and shelf life was investigated. The data presented comprises microbiome and proteome profiles of control and HP-processed sea bass fillets from 1 to 67 days of isothermal storage at 2 °C. Bacterial diversity was analysed by Illumina high-throughput sequencing of the 16S rRNA gene in pooled DNAs from control or HP-processed fillets after 1, 11 or 67 days and the raw reads were deposited in the NCBI-SRA database with accession number PRJNA517618. Yeast and fungi diversity were analysed by high-throughput sequencing of the internal transcribed spacer (ITS) region for control and HP-processed fillets at the end of storage (11 or 67 days, respectively) and have the SRA accession number PRJNA517779. Quantitative label-free proteomics profiles were analysed by SWATH-MS (Sequential Windowed data independent Acquisition of the Total High-resolution-Mass Spectra) in myofibrillar or sarcoplasmic enriched protein extracts pooled for control or HP-processed fillets after 1, 11 and 67 days of storage. Proteome data was deposited in the ProteomeXchange Consortium via the PRIDE partner repository with the dataset identifiers PXD012737. These data support the findings reported in the associated manuscript "High pressure processing of European sea bass (Dicentrarchus labrax) fillets and tools for flesh quality and shelf life monitoring", Tsironi et al., 2019, JFE 262:83-91, doi.org/10.1016/j.jfoodeng.2019.05.010.FCT (Foundation of Science and Technology) COFASP/0002/2015; Portuguese Foundation for Science and Technology UID/Multi/04326/2019 POCI-01-0145-FEDER007440 UID/NEU/04539/2019info:eu-repo/semantics/publishedVersio

Career progression and formal versus on-the-job training

We develop a dynamic discrete choice model of training choice, employment and wage growth, allowing for job mobility, in a world where wages depend on firm-worker matches, as well as experience and tenure and jobs take time to locate. We estimate this model on a large administrative panel data set which traces labour market transitions, mobility across firms and wages from the end of statutory schooling. We use the model to evaluate the life-cycle return to apprenticeship training and find that on average the costs outweigh the benefits; however for those who choose to train the returns are positive. We then use our model to consider the long-term lifecycle effects of two reforms: One is the introduction of an Earned Income Tax Credit in Germany, and the other is a reform to Unemployment Insurance. In both reforms we find very significant impacts of the policy on training choices and on the value of realised matches, demonstrating the importance of considering such longer term implications

Information Acquisition and Adoption of Organic Farming Practices: Evidence from Farm Operations in Crete, Greece

The objective of the paper is to model the degree of organic farming adoption as well as the importance of technical information acquisition in the adoption decision process. In doing so, a trivariate ordered probit model is specified and implemented in the case of organic farming adoption in Crete, Greece. The results suggest that the decisions of information acquisition and adoption are indeed correlated and different farming information sources play a complementary role. Policies required to encourage organic farming adoption should be primarily structural while the provision of technical information is more crucial than conversion subsidies if total organic adoption is to be pursued.Technology adoption, information acquisition, organic farming, Crete, Greece

Information Acquisition and Adoption of Organic Farming Practices

This study offers an empirical framework for analyzing farmers' joint decisions to adopt organic farming practices and to seek technical (i.e., farming) information from various sources. To that end, a trivariate ordered probit model is specified and implemented in the case of organic land conversion in Crete, Greece. Findings suggest that the decisions of information acquisition and organic land conversion are indeed correlated, and different farming information sources play a complementary role. Structural policies improving the farmer's allocative ability are found to play an important role in encouraging organic farming adoption.Crete, Greece, information acquisition, organic farming, technology adoption, Farm Management,

The MNC as a Knowledge Structure The Roles of Knowledge Sources and Organizational Instruments in MNC Knowledge Management

Recent research on the differentiated MNC has concerned knowledge flows between MNC units. While linking up with this literature, we extend in two directions. First, we argue that conceptualizing the MNC as a knowledge structure furthers the understanding of intra-MNC knowledge flows. Thus, we see MNC knowledge elements as being structured along such dimensions as their type and degree of complementarity to other knowledge elements, and their sources, for example, whether they are mainly developed from external or internal knowledge sources. These dimensions matter in terms of knowledge flows, because they influence the costs and benefits of knowledge transfer and, hence, the actual level of knowledge transferred. Second, based on this conceptualization, we argue that MNC management can influence the development, characteristics and transfer of knowledge through choices regarding organizational instruments (control, motivation and context). We test six hypotheses derived from these arguments against a unique dataset on subsidiary knowledge development. The dataset includes information on organizational instruments, sources of subsidiary knowledge, and the extent of knowledge transfer to other MNC units. It covers more than 2,000 subsidiaries located in seven different European countries.Knowledge structure, complementarity, knowledge transfer, the MNC

Asset Accumulation, Fertility Choice and Nondegenerate Dynamics in a Small Open Economy

This paper shows that the assumption of elastic fertility choices represents an unconsidered way of introducing nondegenerate dynamics within an immortal small open economy, facing perfect capital mobility and no adjustment costs associated with capital accumulation, and having a fixed discount rate. The transient dynamics are obtained since fertility, which enters the Euler equation, renders the growth of the marginal utility of wealth strictly interconnected with wealth accumulation. The comparative dynamics are studied for two exogenous shocks: an increase in thrift, which changes fertility and capital formation permanently, and an increase in government spending, which alters fertility and capital stock temporarily.Endogenous population, Capital accumulation, Current account, Transitional dynamics

Universities and economically depressed regions: how ‘attractive’ is the University of Évora?

As it is well known, universities constitute sources of important multiplier effects on the economic activity of the regions where they are located. Plainly, in the case of economically depressed regions, the importance of universities becomes higher. This is certainly the case with the University of Évora as being located in the Alentejo, one of the poorest regions at the European Union level, it have been contributing to the attraction of economic activity. Besides the direct effect on the economic activity of the Alentejo, the University of Évora also have been exerting demographic effects, on the one hand, by allowing people to become residents on the region and, on the other hand, by attracting students which normally become residents during the period of time required to conclude their academic degrees. The paper explores this last effect by the analysis of how and why the University of Évora is chosen by students coming from all over the country (and from abroad). This analysis, which is done through the use of econometric techniques, also indicates which are the decisive factors for the attraction exerted by the University of Évora, in general, and by its degree courses, in particular, on the candidate students.
