The Tale of Two research Communities: The Diffusion of Research on Productive Efficiency
No full textThe field of theoretical and applied efficiency analysis is pursued both by economists and people from operational research and management science. Each group tends to cite a different paper as the seminal one. Recent availability of extensive electronically accessible databases of journal articles makes studies of the diffusion of papers through citations possible. Research strands inspired by the seminal paper within economics are identified and followed by citation analysis during the 20 year period before the operations research paper was published. The first decade of the operations research paper is studied in a similar way and emerging differences in diffusion patterns are pointed out. Main factors influencing citations apart from the quality of the research contribution are reputation of journal, reputation of author, number of close followers; colleagues, “cadres of protégés”, Ph.D. students, and extent of network (“invisible college”). Such factors are revealed by the citing papers. In spite of increasing cross contacts between economics and operations research the last decades co-citation analysis reveals a relative constant tendency to stick to “own camp” references.Farrell efficiency measures, data envelopment analysis, DEA, bibliometry
The contribution of innovations in total factor productivity of organic olive enterprises
No full textThis paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform better than less innovative ones regarding TFP and efficiency scores. Adoption of innovations has a positive contribution in the reduction of inefficiency and profit-loss. The rate of technical difference is always positive in the formulation of TFP difference whereas the adjustment in innovativeness effects varies among the innovation groups. Finally, high-tech capital is more or less under-utilized, regardless of the innovation group.Innovations, total factor productivity, profit efficiency, organic farming, Greece, Productivity Analysis,
Handedness-Dependent Brain Networks Re-organization During Visuo-Motor Task Execution
No full textThe aim of the present study was to investigate handedness-dependent organization and functioning of brain networks during visuomotor integration processes. Specifically, a connectivity study was conducted on EEG traces acquired on a group of healthy volunteers during a resting (baseline) condition and the execution of a visuomotor task with the dominant and non-dominant hands. Our results showed that an enhanced network reorganization is observed in the mu band during the movement performed with the right hand with respect to the baseline condition. Conversely, more evident reorganization was observed for the movement performed with the non-dominant hand when dealing with the beta band. These results suggest that different brain functional reorganization strategies are used to accomplish motor tasks with the two body sides. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG
Association Between Variations in Kinematic Indexes of Manual Dexterity and Mu Rhythm Desynchronization Changes After Action Observation and Motor Imagery
No full textThe Mirror Neuron System functioning have enabled the development of Action Observation and Motor Imagery (AOMI) as effective approaches to enhance manual dexterity. Improvements in manual dexterity can be quantified using kinematic indexes during the execution of clinical and functional tests, and neurodynamical correlates of such changes may also be investigated through EEG recording. The current study aimed at investigating (1) kinematic and EEG mu rhythm desynchronization changes after an AOMI-training in healthy subjects and (2) the association between variations in kinematic indexes of manual dexterity and mu rhythm desynchronization changes induced by AOMI. Thirty healthy subjects performed a 3-week AOMI intervention consisting of the observation and motor imagery of transitive manual dexterity tasks. Manual dexterity assessed through the analysis of kinematic indexes and EEG mu rhythm desynchronizations were analyzed before and after the training. Results showed that AOMI improved kinematic indexes of manual dexterity and induced an increase in murhythm desynchronizations during motor performance. Furthermore, improvements in kinematic indexes of manual dexterity were related to mu rhythm desynchronization changes in central and parietal cortical areas during the execution of NHPT with the left hand. These findings are explanatory of parameters of human movements subtended to sensorimotor system activity changes induced by AOMI and may provide useful information for planning AOMI interventions aimed at enhancing manual dexterity. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG
The ASTAROTH project
No full textThe most discussed topic in direct search for dark matter is arguably the
verification of the DAMA claim. In fact, the observed annual modulation of the
signal rate in an array of NaI(Tl) detectors can be interpreted as the awaited
signature of dark matter interaction. Several experimental groups are currently
engaged in the attempt to verify such a game-changing claim with the same
target material. However, all present-day designs are based on a light readout
via Photomultiplier Tubes, whose high noise makes it challenging to achieve a
low background in the 1-6 keV energy region of the signal. Even harder it would
be to break below 1 keV energy threshold, where a large fraction of the signal
potentially awaits to be uncovered. ASTAROTH is an R\&D project to overcome
these limitations by using Silicon Photomultipliers (SiPM) matrices to collect
scintillation light from NaI(Tl). The all-active design based on cubic crystals
is operating in the 87-150 K temperature range where SiPM noise can be even a
hundred times lower with respect to PMTs. The cryostat was developed following
an innovative design and is based on a copper chamber immersed in a liquid
argon bath that can be instrumented as a veto detector. We have characterized
separately the crystal and the SiPM response at low temperature and we have
proceeded to the first operation of a NaI(Tl) crystal read by SiPM in cryogeny.Comment: proceedings of the LRT 2022 conferenc
On the Convergence of Social Protection Performance in the European Union
No full textIn this article, we use data on five social inclusion indicators (poverty, inequality, unemployment, education and health) to assess and compare the performance of 15 European welfare states (EU15) over a 12-year period from 1995 to 2006. Aggregate measures of performance are obtained using index number methods similar to those employed in the construction of the widely used Human Development Index. These are compared with alternative measures derived from data envelopment analysis methods. The influence of methodology choice and the assumptions made in scaling indicators upon the results obtained is illustrated and discussed. We then analyse the evolution of performance over time, finding evidence of some convergence in performance and no sign of social dumping. (JEL codes: H50, C14, D24) Copyright The Author 2010.
