Introduction: Why (Ever) Define Law and How to Do It

2016

This contribution addresses some problems regarding the two core aspects of Schauer’s proposal discussed by his critics in this book: the method of defining law (his proposal of anti-essentialism) and the definition of law based on the ubiquity of coercion. In this introduction, both aspects will be discussed pushing to the very limit the idea of law as a differentiated phenomenon. This means that legal theory has to take non-state law seriously. But main legal theories in the Nineteenth century are biased by the domestic assumption: law is produced by the nation-state as a coherent and rational system identified by its pedigree and supported by the state’s raw force. According to this idea…

Work, Time and Family: Is It Possible to Identify European Family Working Time Regimes?

2018

Overall in Europe, over the past decades there has been a shift from the male-breadwinner to the dual-earner model, but with a varying pace, and it has even been claimed that the rise of the dual earning households is one of the most significant social trends that has impacted European societies. In order to capture more carefully the variation of the family working time patterns, research has clustered European countries into family working time regimes or clusters. As men’s position in the labour market has been more stable over time, the change in women’s position in the labour markets is the core of explaining the changing family work patterns. Research has shown that family working tim…

Education, Growth and Development

2016

The link between higher-education investment and growth is more relevant when a country’s economy is no longer based on imitation, and begins to rely instead, on innovation as the main engine for growth. The knowledge triangle – research, education and innovation – was a core factor in European efforts to meet the Lisbon strategy and its stated objective that knowledge should help the European economy become the most dynamic knowledge-based one in the world. The failure of the Lisbon strategy was later conducive to a new ambitious scheme, namely Horizon 2020. Human capital, when transposed to educational matters, helps put forward an assessment of the relevance of the neo-Schumpeterian view…

Accurate tuning of mismatched twin-core fiber filters

1998

We have demonstrated a reproducible and accurate way of tuning the coupling wavelength of a mismatched twin-core filter. This method allows high quality all-fiber filters to be implemented with low loss at any desired wavelength over a range of few hundred nanometers from the same fiber. An ~500-nm tuning range is demonstrated, limited only by the measurement setup and not by the technique itself. Highly accurate control of the filtering wavelength in combination with control of filtering strength by adjustment of the length of the twin-core fibers allows complex filter profiles to be implemented by cascading of several different filters. These filters are also very stable to a change in te…

A Theoretical Model to Evaluate the Compressive Behaviour of RС Jacketed Columns

2016

Reinforced concrete (RC) jacketing is becoming increasingly common among the different retrofit techniques for poor RC members, due to its economical and practical advantages. Experimental investigations in the literature have shown that the actual axial capacity of RC jacketed members can be substantially lower than that analytically evaluated by adapting the most common theoretical models for confined concrete. This fact can be explained by taking into account the presence of tensile stresses developing in the concrete, due to a mutual interaction between the inner core and the external jacket. This phenomenon is relevant especially in members where the concrete properties of the jacket a…

The study and optimization of the behavior and energy absorbed in the frontal impact by a rectangular metal workpiece with an Origami core

2021

The bumper systems (beams and face bars) are parts of the car body structure, one of the most important components of an auto vehicle because of its role in absorbing the energy of an impact by deformation. The main objective of this paper is to study, optimize the built shape of the frontal members beams used in the endurance structure of motor vehicles in terms of their ability to absorb internal energy resulting from a frontal impact under the principles of sustainability. The study combines the classical technology used in the construction of vehicles with, the Origami Engineering” technique, which is generally used by NASA, but also by engineers in other fields: aeronautics, nanotechno…

A review of colour center and nanostructure creation in LiF under heavy ion irradiation

2015

A study of radiation damage in LiF crystals under irradiation with MeV–GeV energy ions, from 12C to 238U, at temperatures varying from 8 to 300 K, depending on the ion energy, energy loss and irradiation temperature, is presented. For light ions (12C, 14N) at low fluences, it is mainly color centers that are created. Increasing the fluence leads to the overlapping of tracks and the creation of more complex color centers, defect aggregates and dislocations. For ions with an energy loss above a threshold value (dE/dx = 10 keV nm−1) the tracks exhibit a central core damage region with a radius of 1–2 nm, surrounded by an extended halo which mainly contains single color centers. In this case, i…
