    © 2013 Elsevier B.V. All rights reservedThis paper focuses on the effects of global factors on the saving–investment relationship. We prove that, if investments and savings are affected by idiosyncratic and global components, they must be cointegrated to obtain reliable estimates of the saving-retention coefficient. When global shocks are taken into account throughcommonfactors,wefind that the estimated saving-retention coefficient is close to zero for a panel of 21 OECD countrie

    Dynamics of Laughter: Mithrobarzanes’ Disguise as a Magos in Lucian’s Menippus

    Get PDF
    Amongst the many literary products of the Second Sophistic, few are so exuberant and satirical as those by Lucian of Samosata. In the comic dialogue known as the Menippus or Nekyomanteia (‘The Oracle of the Dead’), he narrates the attempt of the Cynic Menippus to consult with the prophet Tiresias in the underworld. In order to descend into Hades, Menippus needs the guidance of the disciples of Zoroaster, the μάγοι, and he finds his guide in Mithrobarzanes, a Chaldean from Babylon (Nec.6). After some preliminary rituals, Mithrobarzanes prepares Menippus for the katabasis by means of a comic disguise: Menippus has to wear a woollen hat, hold a lyre, and gear himself up with a lion skin to pass for Odysseus, Orpheus, or Herakles (Nec.7). With such description, Lucian trivialises the figures of these mythical heroes on the wake of a well-established comic tradition (e.g. Aristoph. Batr.46-7;495-6). In this study, I argue that Mithrobarzanes’ garments (Nec.8) have a comic value as well, and this is due to the fact that he is not a real μάγος, but a Chaldean from Babylon who needs to wear a μαγική στολή (‘Magian stole’) to disguise himself as a μάγος. To support this interpretation, I shall discuss some key passages (i.e. Apul. Apol.25.9-26.6; Philostr. V.A.1.2;1.26; Hist.Alex.Mag. rec.vet. 1.4.3-4;3.30.6; Hsch. s.v. Χαλδαῖοι) clarifying the meaning of μάγος and Χαλδαῖος, and their semantic association with the term γόης (‘enchanter’). This will allow us to understand that, by means of Mithrobarzanes’ costume, Lucian aims to satirise the figure of the Zoroastrian high priests. This study aims, therefore, to shed light on the hilarious connotation of Mithrobarzanes’ disguise as a μάγος, which will enable us to recover an additional farcical note of Lucian’s Nekyomanteia

    The skulls of Borgo Cerreto (Perugia): medical, surgical, and anatomical activity of Baronio Vincenzi (XVII century)

    In the Sixties of the last century the vault of a 17th century private chapel was opened, revealing three isolated skulls with evidence of surgical and anatomical activity. The chapel was built by Baronio Vincenzi, who lived and practiced medicine in Borgo Cerreto, a village in the province of Perugia, between the 16th and the 17th century. The skull bc 01 belongs to an adult male, aged 25-35 years. It shows a hole on the left front-parietal region (30 x 31 mm), that can be identified as the result of a skull trepanation. The margins of the lesion are regularly smoothed and inclined internally and the diplopic tissues result almost completely obliterated by a cicatricial bone. A bone splinter (10 x 8 mm), completely reabsorbed, can be observed on the right side of the hole. These findings are the proof of a long survival of the subject. X-ray examination confirms a regular process of ossification, without infection. Trepanation was performed with a Hippocratic trypanon, largely used in cranial surgery of Modern Age. The specimen bc 02 is without skullcap and the right upper part of the face; it belongs to an adult male, 25-30 years aged. The cuts were produced by a bone saw with a thin blade. The choice of these regions suggests the willingness to study the basal skull, the right eye cavity and the paranasal sinuses. The skull bc 03 consists only in a skullcap of an adult individual, which shows the signs of a bone saw. In conclusion, the recovery of a trepanned skull, at present the first specimen of this type recovered so far in Umbria, together with two others skulls with the signs of postmortem examination, inside the Vincenzi family vault can be probably related to the professional activity of Baronio. He was an experienced surgeon and a skilled anatomist, who certainly experienced the empirical surgery of the nearby surgical School of Preci, famous throughout Europe for the treatment of urinary bladder stones, cataract as well as the ability in skull trepanation

    Chandra imaging of the ∼\simkpc extended outflow in 1H 0419-577

    The Seyfert 1 galaxy 1H 0419-577 hosts a ∼\simkpc extended outflow that is evident in the [\ion{O}{iii}] image and that is also detected as a warm absorber in the UV/X-ray spectrum. Here, we analyze a ∼\sim30 ks Chandra-ACIS X-ray image, with the aim of resolving the diffuse extranuclear X-ray emission and of investigating its relationship with the galactic outflow. Thanks to its sub-arcsecond spatial resolution, Chandra resolves the circumnuclear X-ray emission, which extends up to a projected distance of at least ∼\sim16 kpc from the center. The morphology of the diffuse X-ray emission is spherically symmetrical. We could not recover a morphological resemblance between the soft X-ray emission and the ionization bicone that is traced by the [\ion{O}{iii}] outflow. we argue that the photoionized gas nebula must be distributed mostly along the polar directions, outside our line of sight. In this geometry, the X-ray/UV warm absorber must trace a different gas component, physically disconnected from the emitting gas, and located closer to the equatorial plane.Comment: accepted for publications A&

    XMM-Newton observation of the ULIRG NGC 6240: The physical nature of the complex Fe K line emission

    Full text link
    We report on an XMM-Newton observation of the ultraluminous infrared galaxy NGC 6240. The 0.3-10 keV spectrum can be successfully modelled with: (i) three collisionally ionized plasma components with temperatures of about 0.7, 1.4, and 5.5 keV; (ii) a highly absorbed direct power-law component; and (iii) a neutral Fe K_alpha and K_beta line. We detect a significant neutral column density gradient which is correlated with the temperature of the three plasma components. Combining the XMM-Newton spectral model with the high spatial resolution Chandra image we find that the temperatures and the column densities increase towards the center. With high significance, the Fe K line complex is resolved into three distinct narrow lines: (i) the neutral Fe K_alpha line at 6.4 keV; (ii) an ionized line at about 6.7 keV; and (iii) a higher ionized line at 7.0 keV (a blend of the Fe XXVI and the Fe K_beta line). While the neutral Fe K line is most probably due to reflection from optically thick material, the Fe XXV and Fe XXVI emission arises from the highest temperature ionized plasma component. We have compared the plasma parameters of the ultraluminous infrared galaxy NGC 6240 with those found in the local starburst galaxy NGC 253. We find a striking similarity in the plasma temperatures and column density gradients, suggesting a similar underlying physical process at work in both galaxies.Comment: 8 pages including 9 figures.

    Some studies suggested a positive effect against cardiometabolic diseases of supplementation of alpha-linolenic acid (ALA, C18:3 n-3) rich foods in pathological subjects, even if the total literature is controversial. In order to clarify ALA-rich chia seed action in hypertensive model with the overt pathology and without drug interference, in the present study the biochemical markers of cardiometabolic diseases (endothelin-1, ET-1; nitric oxide, NO; and bradykinin, BK) in Spontaneously Hypertensive Rats (SHRs) were analysed after 5% chia seed dietary supplementation for five weeks, and compared with the staple raw material wheat and corn. At the end of the experimental period, also plasma antioxidant capacity and inflammatory condition were evaluated. Our results showed that the chia seed group was more oxidized. On the other hand, ET-1 significantly decreased in chia seed group, and there was no difference between groups for NO, BK, and the inflammatory C-reactive protein (CRP). In conclusion, some positive effects of chia seed consumption on cardiometabolic markers in SHRs were observed, despite this the association of chia seeds with antioxidants is suggested to avoid plasma oxidation increase

    Drug addiction among young people: A study of typology and its relevance to treatment programmes

    Get PDF
    On the basis of clinical observation, the authors have classified drug addiction into four types: traumatic, actual, transitional and socio-pathic. Such classification helps in epidemiological research to understand better the distribution of people addicted to a given drug. Each type of addiction differs in respect of onset, evolution, prognosis and certain other characteristics relevant to the treatment of drug-addicted persons. Thus, the classification helps in making an appropriate selection of a treatment method and in the evaluation of a treatment programme. It has been observed that (a)traumatic and actual types of addiction have a much more favourable prognosis; (b)individual psychotherapy and support in a medical setting is effective for the traumatic type of addiction; (c)treatment in a family setting appears to be suitable for actual and transitional types of addiction; and (d)the therapeutic community may prove to be effective in the treatment of persons affected by socio-pathic type of addiction
