La thématique de la lutte et l’ἀγὼν θεῖος dans 4 Maccabées
No full textThis article argues for the importance of a linguistic analysis of biblical texts and proposes such an analysis in relation to the language of 4 Maccabees and the metaphors its author uses to describe the battle between the pious Jews and the king Antiochus IV, who wants to forcefully convert them. The expressions taken from the war lexicon are analysed in the light of the relationship between Hellenistic Judaism and the cultivated Greek language. Although these textual instances provide a detailed framework for the construction of the Greek enemy by the Jews, they nevertheless clearly show the high level of acculturation they had acquired in relation to the colonial language
Dendritic cells in acute promyelocytic leukaemia.
No full textDendritic cell (DC) differentiation was investigated in samples from two acute promyelocytic leukaemia (APL) patients with classic translocation t(15;17)(q22;q21). After 18 d of culture in the presence of granulocyte-macrophage colony-stimulating factor, interleukin 4 and tumour necrosis factor alpha, 10-15% of pathological promyelocytes had differentiated into DC-like cells, as demonstrated by immunological and functional characteristics and by analysis of CD1a+ cells. In one patient, analysed at relapse and after developing a picture of secondary myelodysplastic syndrome (MDS), three different populations of DCs were demonstrated, two of which derived from pathological myeloid precursors (the APL and the MDS clones). This patient's DCs also presented abnormal dextran uptake. Our results demonstrated that pathological myeloid precursors in APL can differentiate into DC-like elements and that different populations of pathological DCs may coexist in the same patient
The right person for the right job: workers’ prosociality as a screening device
No full textThe impact of workers’ non-pecuniary motivation on their productivity is a fundamental issue in labor economics. Previous studies indicate that prosocially motivated workers may perform better when assigned to jobs having socially desirable implications – even if effort is non-contractible and they are offered a low-powered fixed-compensation scheme – as compared to a standard job with an effort-contingent payment. This suggests that profit-maximizing employers should assign workers to different jobs, based on workers’ prosociality. We run an experiment to explore the link between workers’ prosociality and their level of effort under a prosocial and a standard job. Our experimental results provide some support to the hypothesis that selfish employers exploit the information on workers’ prosociality to assign them the type of job that would be most profitable from the firm’s perspective. However, the prosocial motivation of employers emerges as a second important determinant of their contract choice: employers’ prosociality drives their contract choice, when the worker is not prosocial
Combined experimental and numerical investigations on the roughness effects on the aerodynamic performances of LPT blades
No full textThe aerodynamic performance of a high-load low-pressure turbine blade cascade has been analyzed for three different distributed surface roughness levels (Ra) for steady and unsteady inflows. Results from CFD simulations and experiments are presented for two different Reynolds numbers (300000 and 70000 representative of take-off and cruise conditions, respectively) in order to evaluate the roughness effects for two typical operating conditions. Computational fluid dynamics has been used to support and interpret experimental results, analyzing in detail the flow field on the blade surface and evaluating the non-dimensional local roughness parameters, further contributing to understand how and where roughness have some influence on the aerodynamic performance of the blade. The total pressure distributions in the wake region have been measured by means of a five-hole miniaturized pressure probe for the different flow conditions, allowing the evaluation of profile losses and of their dependence on the surface finish, as well as a direct comparison with the simulations. Results reported in the paper clearly highlight that only at the highest Reynolds number tested (Re=300000) surface roughness have some influence on the blade performance, both for steady and unsteady incoming flows. In this flow condition profile losses grow as the surface roughness increases, while no appreciable variations have been found at the lowest Reynolds number. The boundary layer evolution and the wake structure have shown that this trend is due to a thickening of the suction side boundary layer associated to an anticipation of transition process. On the other side, no effects have been observed on the pressure side boundary layer

Enlisting accounting history in the contest between competing visions of accounting systems: Tommaso Zerbi and the origin of double-entry bookkeeping
No full textBiographical research has attracted a significant level of interest from the accounting history community. Nevertheless, most of these studies are focused on documenting the life and work of renowned accounting scholars and practitioners. The present study seeks to investigate the work of an author who is yet to attract the attention of the international community, Tommaso Zerbi, in close connection with the social and academic context in which his work was developed. The study emphasises the political and militant role that accounting history may play in academic communities by showing how accounting history research is not necessarily a value-free endeavour in the generation of new knowledge but can be enlisted in ensuring the success of a specific understanding of accounting systems in the context of academic struggles. Although mainly aiming at contributing to a national debate, the originality and value of Zerbi’s work ended up offering a significant contribution to the international debate on the origin of double-entry bookkeeping
Brain Asymmetry and Its Effects on Gait Strategies in Hemiplegic Patients: New Rehabilitative Conceptions
No full textBrain asymmetry is connected with motor performance, suggesting that hemiparetic patients have different gait patterns depending on the side of the lesion. This retrospective cohort study aims to further investigate the difference between right and left hemiplegia in order to assess whether the injured side can influence the patient’s clinical characteristics concerning gait, thus providing insights for new personalized rehabilitation strategies. The data from 33 stroke patients (17 with left and 16 with right hemiplegia) were retrospectively compared with each other and with a control group composed of 20 unaffected age-matched individuals. The 3D gait analysis was used to assess kinematic data and spatio-temporal parameters. Compared to left hemiplegic patients, right hemiplegic patients showed worse spatio-temporal parameters (p < 0.05) and better kinematic parameters (p < 0.05). Both pathological groups were characterized by abnormal gait parameters in comparison with the control group (p < 0.05). These findings show an association between the side of the lesion—right or left—and the different stroke patients’ gait patterns: left hemiplegic patients show better spatio-temporal parameters, whereas right hemiplegic patients show better segmentary motor performances. Therefore, further studies may develop and assess new personalized rehabilitation strategies considering the injured hemisphere and brain asymmetry
Effects of different loading on the bifurcation of annular elastic rods: theory vs. experiments
No full textThe bifurcation problem of a circular Euler-Bernoulli rod subject to a uniform radial force distribution is investigated under three distinct loading conditions: (i.) hydrostatic pressure, (ii.) centrally-directed, and (iii.) dead load. Previous studies on this apparently \u27familiar\u27 structural problem have yielded controversial results, necessitating a comprehensive clarification. This study shows that results previously labelled as \u27correct\u27 or \u27wrong\u27 simply refer to different external constraints, whose presence becomes necessary only for the two latter loads, (ii.) and (iii.). Moreover, the paper presents the first experimental realization of a circular rod subjected to centrally-directed loads. The experimental findings align with the theoretical predictions and show the exploitation of a new type of load acting on a continuous structural element. The feasibility of this load is demonstrated through the use of inextensible cables and opens the way to applications in flexible robotics when cables are used for actuation.25 pages, 10 figure
