Diploma Effects by Gender in the Spanish Labour Market

2006

.  The aim of this paper is to contrast the nature of the schooling effect on earnings in the Spanish labour market in terms of gender. Hungerford and Solon's (Review of Economics and Statistics 69: 175–177, 1987) methodology is used to distinguish between the returns to schooling arising from mere years of schooling as a reflection of their productivity-enhancing contribution (human capital) and the returns to schooling arising from certificates (diploma effects) as signals of the individual's productivity (sheepskin effects) or as credentialism. The results show evidence only of diploma effects in Upper Secondary Studies for men.

Mapping Economic Activity in the European Union: Do Ownership, Industry and Location Matter?

2020

The paper proposes a new method for analysing the structure and dynamics of economic activity undertaken by locally owned and foreign-owned companies within the European Union. We employ an unsupervised learning algorithm that generates a neural network depicted on Kohonen maps and offering a clustering of companies with a different ownership (local and foreign) from various industries and countries of the European Union during 2009–2016. The research methodology, based on a self-organizing map (SOM) algorithm, belongs to a class of neural networks trained to organize data so that unknown patterns may be discovered, thus leading to results that cannot be attained by more traditional cluster…

Scientometric Picture of the Evolution of the Literature of Automation in Spectroscopy and Its Current State

2006

Abstract The current study focuses on the status of automation and mechanization in spectroscopy for analytical chemistry publications compiled during the period 1980–2006, in Analytical Abstracts. Flow injection analysis (FIA), sequential injection analysis (SIA), multicommutation, and monosegmented and segmented flow strategies were considered. For assessing the evolution of scientific productivity, the total number of publications concerned with the different methodologies was evaluated. In order to provide a picture of the state of the art of this field, the most important journals, the most active authors, and the most productive countries in the field of automation were evaluated in t…

Political Consumerism and Food Community Networks

2011

European society, with its steadily increased welfare levels, is not only concerned about food (safety, prices), but also on other aspects such as biodiversity loss, landscape degradation, pollution of water, soil and atmosphere. To a large extent these concerns can be translated into a wider concept named sustainable development defined as a normative concept by Morgan and Sonnino (2008). Sustainability in the food chain means approaching a new emerging vision of a sustainable agro-food system introducing an institutional dimension to take into account. Among different attempts to conjugate such concepts, there is one that is taking place in many Regions of Italy. In the last years spontan…

Climate Effects on Breeding Phenology of Peregrine and Lanner Falcons in the Mediterranean

2022

We explored the effects of weather on the timing and reproduction of the Mediterranean Peregrine Falcon Falco peregrinus brookei and the Lanner Falcon F. biarmicus feldeggii living on the Mediterranean island of Sicily. We found that the start date of incubation has changed during 1979–2019 and analysed whether incubation timing affected the productivity of both populations and whether the change of incubation date and the quality of breeding sites depended on climatic conditions. Overall spring temperature and rainfall increased on Sicily and the incubation date of the Peregrine and the Lanner Falcon has shifted to be about one week later over the time period 1979 to 2019. Linear mixed mod…

A System Dynamics Approach to Evaluate Incentive-based Policies, Human Resource Motivation and Performance of Public Sector Organizations

2014

This paper tries to analyze - through a System Dynamics approach - positive and negative effects caused by human resources‘ (de)motivation in terms of productivity and quality of performance in public sector organizations. Therefore, motivation is here meant as an inclination to fill a gap between a desired and an actual level of productivity; this can be achieved through a set of policies aimed to encourage, sustain and address human resource behaviour in a working setting. As a consequence of such policies, public sector organizations would increase their productivity and effectiveness, thereby improving the level of wealth to the community they work for. But how does work motivation infl…

Disentangling conditional effects of multiple regime shifts on Atlantic cod productivity

2020

AbstractRegime shifts are increasingly prevalent in the ecological literature. However, definitions vary, and many detection methods are subjective. Here, we employ an operationally objective means of identifying regime shifts, using a Bayesian online change-point detection algorithm able to simultaneously identify shifts in the mean and(or) variance of time series data. We detected multiple regime shifts in long-term (59-154 years) patterns of coastal Norwegian Atlantic cod (>70% decline) and putative drivers of cod productivity: North Atlantic Oscillation (NAO); sea-surface temperature; zooplankton abundance; fishing mortality (F). The consequences of an environmental or climate-relate…

Co-evolutionary coupling leads a way to a novel concept of R&D - Lessons from digitalized bioeconomy

2020

Given the increasing role of research and development (R&D) in competitive markets in the digital economy while confronting the dilemma between R&D expansion and a productivity decline, transformation of the R&D model has become a crucial subject for global digital leaders. The authors of this paper postulate that neo open innovation harnessing the vigor of external innovation resources which then developed into a new concept of R&D that self-transforms during an R&D process initiated by Amazon by coupling with users. The authors further develop these postulates by proposing the embedding of a growth characteristic identical to biological coupling. An empirical analysis focusing on the fore…

Harnessing soft innovation resources leads to neo open innovation

2019

Advancement of the digital economy has transformed the concept of the growth crossover in nations and firms, both concerning input and output. Advanced economies have been confronting a dilemma between input increases and output decreases. Contrary to traditional expectations, excessive increase in input has resulted in a productivity decline in output. A solution to this dilemma can only be expected by harnessing the vigor of soft innovation resources that lead to neo open innovation in the digital economy. This paper attempts to demonstrate this hypothetical view. Based on an empirical analysis of the development trajectories of 140 countries and 500 global ICT firms, dynamism, resulting …
