European option pricing under cumulative prospect theory with constant relative sensitivity probability weighting functions
In this contribution, we evaluate European financial options under continuous cumulative prospect theory. In prospect theory, risk attitude and loss aversion are shaped via a value function, while a probability weighting function models probabilistic risk perception. We focus on investors’ probability risk attitudes, as probability weighting may be one of the possible causes of the differences between empirically observed options prices and theoretical prices obtained with the Black and Scholes formula. We consider alternative probability weighting functions; in particular, we adopt the constant relative sensitivity weighting function, whose parameters have a direct interpretation in terms of curvature and elevation. Curvature models optimism and pessimism when one moves from extreme probabilities, whereas elevation can be interpreted as a measure of relative optimism. We performed a variety of numerical experiments and studied the effects of these features on options prices and implied volatilities
The Medical Debate about Prostitution and Venereal Diseases in Yugoslavia (1918-1941)
The article aims at illustrating the main features of the medical debate about prostitution
and venereal diseases in the first Yugoslavia, and the role played by physicians in shaping prostitution
policies in that country between the two world wars. The Yugoslav medical debate, while
sharing many of the same arguments and characteristics with analogues debates in Europe and
beyond, also reveals some peculiar aspects. These aspects were related to the Habsburg and
Ottoman legacies, the phenomenon of Bosnian endemic syphilis, the establishment of the new
Yugoslav state, and the South-East European context. This resulted firstly in a multifaceted debate,
with internal discrepancies and a dynamic development during the time; secondly, in a relevant role
played by physicians as policy consultants and even policy makers with marked eugenic tones,
which were in full accordance with the social engineering and nation-building projects of the political
elite of this newly founded state

Whole-body low-dose CT recognizes two distinct patterns of lytic lesions in multiple myeloma patients with different disease metabolism at PET/MRI
We evaluated differences in density and 18 F-FDG PET/MRI features of lytic bone lesions (LBLs) identified by whole-body low-dose CT (WB-LDCT) in patients affected by newly diagnosed multiple myeloma (MM). In 18 MM patients, 135 unequivocal LBLs identified by WB-LDCT were characterized for inner density (negative or positive Hounsfield unit (HU)), where negative density (HU < 0) characterizes normal yellow marrow whereas positive HU correlates with tissue-like infiltrative pattern. The same LBLs were analyzed by 18 F-FDG PET/DWI-MRI, registering DWI signal with ADC and SUV max values. According to HU, 35 lesions had a negative density (− 56.94 ± 31.87 HU) while 100 lesions presented positive density (44.87 ± 23.89 HU). In seven patients, only positive HU LBLs were demonstrated whereas in eight patients, both positive and negative HU LBLs were detected. Intriguingly, in three patients (16%), only negative HU LBLs were shown. At 18 F-FDG PET/DWI-MRI analysis, negative HU LBLs presented low ADC values (360.69 ± 154.38 × 10 −6 mm 2 /s) and low SUV max values (1.69 ± 0.56), consistent with fatty marrow, whereas positive HU LBLs showed an infiltrative pattern, characterized by higher ADC (mean 868.46 ± 207.67 × 10 −6 mm 2 /s) and SUV max (mean 5.04 ± 1.94) values. Surprisingly, histology of negative HU LBLs documented infiltration by neoplastic plasma cells scattered among adipocytes. In conclusion, two different patterns of LBLs were detected by WB-LDCT in MM patients. Both types of lesions were indicative for active disease, although only positive HU LBL were captured by 18 F-FDG PET/DWI-MRI imaging, indicating that WB-LDCT adds specific information
