Niphargus graecus Karaman S. 1934
No full textNiphargus graecus Karaman S., 1934 Published records: Karaman S. (1934); Karaman G.S. (2017a). Distribution: Endemic to Greece: Central Greece (IO); Western Greece (IO); Peloponnese (IO). Type material: Holotype: male 10 mm on 4 slides (217/1-217/4), 217 = Akrokorinth (Acrocorinth), spring (central part of Greece), 19.06.01931, 3 exp. (leg. Hans Stadler),,. Paratype: male 6 mm (217/5), same data as for holotype,. Examined material: G-248 (= Sp 313), Delphes, fountain (central part of Greece), 24.04.1954, 7 exp. (leg. K. Lindberg), Karaman G.S.

Remarks: Recently, Karaman G.S. (2017a) has redescribed this species, using the original material and additional specimens from the central and western part of Greece. According to the author, N. graecus and N. aitolosi have morphological similarities, sharing the same locality at the lower part of Acheloos system, including the lakes of Lysimachia and Trichonida. Molecular analysis of N. graecus from all known localities is therefore required to solve the taxonomis status of different populations. Etymology: Species epithet is derived from the country of origin, Greece.Published as part of Ntakis, Alexandros, Karaouzas, Ioannis, Fišer, Cene & Stoch, Fabio, 2020, An annotated checklist of the Niphargidae (Crustacea: Amphipoda) of Greece, pp. 517-544 in Zootaxa 4772 (3) on page 529, DOI: 10.11646/zootaxa.4772.3.5, http://zenodo.org/record/385661

Remarks: Relatively small species described by Karaman G.S. (1917f) from two distant geographical regions in Greece, although within the same ecoregion. The female holotype of N. fautor is located in the same type locality with N. cymbalus. This species can be found along the southern coasts of the PeloponneseKaraman G.S. 1917f). Specimens collected by the second author (I. Karaouzas) from Karya stream estuary (South Peloponnese) have shown some differences with Karaman’s description, thus indicating a morphologically distinct population which needs to be revised. Etymology: The specific name fautor is referring to the Latin word “fautor” (protector, friend).Published as part of Ntakis, Alexandros, Karaouzas, Ioannis, Fišer, Cene & Stoch, Fabio, 2020, An annotated checklist of the Niphargidae (Crustacea: Amphipoda) of Greece, pp. 517-544 in Zootaxa 4772 (3) on pages 528-529, DOI: 10.11646/zootaxa.4772.3.5, http://zenodo.org/record/385661
Covid-19, sovereign risk and monetary policy: Evidence from the European Monetary Union
No full textThis paper investigates the impact of Covid-19 pandemic and monetary policy measures adopted by the European Central Bank (ECB) on the sovereign risk for the European Monetary Union (EMU) countries for the period between March-2020 and November-2020 using daily data. The impact of Covid-19 and monetary policy shocks on the credit default swap rates and bond yields are investigated relying on a fixed effects panel regression model for five core (Germany, France, Austria, Netherlands, Belgium) and three periphery (Italy, Portugal and Spain) countries. To investigate the cross-country differences in responses, the interactions of the independent variables with periphery dummy and other country-specific variables are included in the regressions. The results of the empirical analysis suggest that Covid-19 shock increased the sovereign risk in the periphery EMU countries significantly and monetary policy measures have been effective in easing financial conditions in these countries. The results are insignificant for the core countries. The results also show that financial stability alleviates the negative impact of Covid-19 on the sovereign risk

Small to medium-sized species. Ozophores located on lateral edges of dorsum (type 1 after Juberthie 1970). Narrow frontal edge of dorsum closely covers basal article of chelicerae on its terminal half, after which basal article of chelicerae rises sharply on its dorsal side, forming a prominent transverse ridge. At height of transverse ridge of chelicerae, a medially oriented ventral process present. Distal cheliceral article wide and stout (its basal part twice as long as wide). Pedipalp tibia as long as or longer than tarsus. Coxal lobes I wide, in basal part as long as wide; basal part longer than distal part; coxal endites I continuous along its entire length. Coxal lobes II cup-shaped; about 2.5 times (2.3–2.7) as wide as long, with almost straight frontal margins. Metatarsi of legs elongated (longer than half of tarsal length), first two pairs subdivided in ornamented astragalus and smooth calcaneus (Fig. 1 А). Claws of legs III–IV with teeth (Fig. 1B–F) (also II in all except Cimmerosiro rhodiensis gen et sp. nov.). Corona analis: sternites 8 and 9 medially fused, tergite IX free. Sensitive structures named “subapical process” or “processus sensitif” (Juberthie 2000) (Fig. 2A–E) located dorsally on tarsi of legs I–II conspicuous and not tapering toward distal portion at all (Willemart & Giribet 2010) or only shortly near tip. Female genital orifice posterior margin thick, wide and smooth (Fig. 2F). Ovipositor short, with small number of articles (8–10). Ovipositor lobi without terminal plumose setae; setation concentrated on their dorsal side (Fig. 3), in Sironidae evenly distributed. Males without anal glands. In contrast to other Cyphophthalmi, this family is characterized by a rather uniform structure of the ventral prosomal compleX. The differences between the species of this family are more pronounced in the genital structures of both sexes.</p> Remarks <p> Working on this study, the first author discovered a hitherto unknown sensory organ (sensilla) of Cyphophthalmi, situated medially on the dorsal side of the pedipalp coxae (Fig. 4). It was overlooked in previous studies. In Sironidae (which were in focus), it is represented by a bristle-like structure and looks more like a mechanoreceptor. That structure is a differentiating character between members of the new family and Sironidae, from which it is here separated. In parasironids, the organ forms sensilla that are voluminous, with more or less expressed lobes (Figs 4 A-D), while in sironids they are more bristle-like (Fig. 5). A brief overview of a small sample of available material shows that this organ is present in most of Cyphophthalmi in various forms. It is not recognized in <i>Tucanogovea shusteri</i> Karaman, 2013 or a specimen of <i>Metagovea</i> sp. (Neogoveidae). In parasironids, it is membranous, more or less voluminous (they shrink when drying), suggesting a possible hygroreceptive role. It is similar in structure in Pettalidae and <i>Suzukiellus sauteri</i> (Roewer, 1916). In <i>Ankaratra franzi</i> Shear & Gruber, 1996 it seems more complex, as well as in <i>Meghalaya</i> sp. (Stylocellidae) (Fig. 4E–F). Perhaps this character may have some importance in phyletic analyses of Cyphophthalmi, and it is worth being investigated in more detail.</p> <p>The structure of the pedipalp coxae shows a strong phylogenetic signal in Cyphophthalmi. They are remarkably different among representatives of two families. In Sironidae it is wider along the sagittal axis than long (Fig. 6A–C) and the articulation with the trochanter is eccentrically placed towards the ventral side. In Parasironidae (Fig. 6D) it is as wide as long, and the articulation is centered in the middle of its width. In addition, the pedipalp coxal lobi in Parasironidae are positioned more ventrally to the coxae compared to in Sironidae.</p> <p> The setation of the ovipositor terminal lobi in Parasironidae is specific and remarkably different from the situation in Sironidae. Beside the absence of plumose setae, almost all setae are located on the dorsal side, while in Sironidae they are evenly distributed (Karaman 2009: figs 4–5). On the ventral side, there is only a pair of setae on the basal third of the lobi and a subterminal pair. This, together with the fact that the ventral prosomal complex is quite conservative in this group and that an anal gland is absent, suggests a possibly different way of spermatophore transfer than the one presented in Karaman (2005a). In <i>Odontosiro lusitanicus</i> Juberthie, 1962 the ovipositor setation is similar to that in parasironids, with the difference that one laterodistal seta is plumose (Juberthie 1962: fig. 9). This character mode may be a reflection of the phyletic closeness of this species to the family Parasironidae, despite numerous and significant differences, or a symplesiomorphic feature of phyletically distant taXa.</p> <p>Characters such as the setation and number of claw teeth show a certain degree of variability among specimens and even aberrations, but do not affect their importance as differential characteristics between genera and species.</p> Distribution <p>Disjunct distribution in the Mediterranean from the eastern slopes of the Pyrenees in the west to the Transcaucasus in the east.</p>Published as part of <i>Karaman, Ivo M., Mitov, Plamen G. & Snegovaya, Nataly, 2024, Parasironidae fam. nov., a Cimmerian lineage of Mediterranean Cyphophthalmi (Opiliones), with the description of three new genera and four new species, pp. 173-209 in European Journal of Taxonomy 921 (1)</i> on pages 175-180, DOI: 10.5852/ejt.2024.921.2427, <a href="http://zenodo.org/record/10656519">http://zenodo.org/record/10656519</a>

The Infl uence of Ljubo Karaman on Anđela Horvat’s Conservation Work
No full textRad u Konzervatorskom zavodu u Zagrebu za vrijeme ravnateljstva Ljube Karamana (1941.–1950.), tadašnje rasprave i kritike, imale su velik udio u usmjeravanju i oblikovanju konzervatorskog rada Anđele Horvat. Naglasak rada je na metodologiji i primjeni Pravilnika za čuvanje starina većih mjesta u NR Hrvatskoj te sudjelovanje u predlaganju zakonske regulative o zaštiti kulturnih dobara. Za usporedbu autorica opisuje angažman za izradu Pravilnika grada Šibenika (Karaman, 1931.) i Siska (Karaman i Horvat, 1942. i 1948.), odnosno polazišta Anđele Horvat i Ljube Karamana o »stvaralačkom stavu« u konzervaciji spomenika, funkciji spomenika, jednakovrijednosti stilova i restauratorskim postupcima.Anđela Horvat dedicated her entire life to the protection of cultural monuments, from the very first days when, in a time of war, she accepted Gjuro Szabo’s invitation to become a research assistant in the Directorate for Cultural Heritage Protection. A month after her appointment, Ljubo Karaman became the head of the Directorate (in August 1941), who modernized the organization of the Directorate’s activities through individual approach to every employee. As a »female conservator« Anđela Horvat was at fi rst considered unfi t for fi eld work, and was assigned to archivist tasks (the Szabo archives and Committee acts from 1910 to 1940). Her persistence and potential were soon noticed by Karaman. She started conducting fi eld trips to different areas of inland Croatia, which resulted in systematic analyses of collected data and continual publication of the results. From Karaman she adopted the moto »to travel, to travel and to travel«, because conservators must maintain constant contact with the area of their jurisdiction and keep track of the events occurring there. The paper pays special attention to their dedication to the drafting of the Book of Regulations for the Preservation of Antiquities and Larger Cities, introduced by Karaman on the basis of his Split experience. Anđela Horvat frequently collaborated with Karaman on the project, bringing up to date the existing books of regulations with regard to current events and situations, such as the Books of Regulations for the cities Šibenik (1931) and Sisak (1948). Anđela Horvat was a true pupil of Karaman and Szabo: she adopted all postulates of Riegl and Dvořák’s school even prior to the publication of Karaman’s Considerations under the Slogan »Conserve, not Restore« (Razmatranja na krilatici »konzervirati a ne restaurirati«), and complemented them by thorough long-term archival research. The author compares their views of the »creative attitude« of conservators in the forementioned Karaman’s essay and in Horvat’s unpublished work Conservation Problems of Sacral Monuments of Zagreb Archdiocese (Konzervatorski problemi crkvenih spomenika zagrebačke nadbiskupije; 1956)
Gronella Barnard & Karaman 1991
No full textGronella Barnard & Karaman, 1991 Gronella Barnard & Karaman, 1991: 489. Type species. Anonyx groenlandica Hansen, 1888, original designation. Included species. Gronella includes two species: G. groenlandica (Hansen, 1888); G. lobata (Chevreux, 1907). Diagnostic description. Antenna 1 flagellum article 1 lacking robust seta on distal margin; accessory flagellum forming cap. Antenna 2 flagellum articles 3–5 slender, with strong brush setae on the anterior margin. Mandibular incisor curved; molar with reduced column and convex triturating surface (button); palp attached midway. Maxilla 1 ST-7 cuspidate along distomedial margin; ST-D slender, apically cuspidate. Maxilliped outer plate with apical robust setae. Gnathopod 1 subchelate; coxa large, slightly shorter than coxa 2, tapering; carpus shorter than propodus; propodus palm acute or transverse, straight. Pereopod 4 coxa with well developed posteroventral lobe. Uropod 2 inner ramus constricted. Uropod 3 rami with plumose setae in male, absent in female. Telson moderately cleft. Remarks. Gronella appears to be the sister taxon of Tryphosa. The only clear distinction between these genera is that Gronella has a tapering gnathopod 1 coxa, the setal-teeth of maxilla 1 are less cuspidate and apparently in females the rami of uropod 3 do not develop plumose setae. Gronella is also a sister taxon to Tryphosella which has a tapering first coxa and also a cap on the accessory flagellum. The main difference between these genera is the constricted inner ramus on uropod 2 that occurs in Gronella but not in Tryphosella. The other apparent difference is the structure of the maxilla 1 setal-teeth, most noticeable in ST-7 which is serrate along the entire curved medial margin in Tryphosella (see Lowry & Stoddart 2011), but serrate distally in Gronella groenlandica, with a smooth, straight medial margin. Tryphosa nana has setal-teeth more similar to species of Tryphosella. Two species, Tryphosella propinqua (Chevreux, 1926) from deep water off Portugal and Tryphosella spitzbergensis (Chevreux, 1926) from the Norwegian Arctic, may also belong to Gronella. Neither the seta-teeth of maxilla 1 nor the rami of uropod 2 have ever been illustrated or described for T. propinqua so that the critical characters which determine its generic status are not known and it cannot be definitely placed in either Gronella or Tryphosella. Chevreux (1926) shows a cap on the accessory flagellum and a broadly tapering gnathopod 1 coxa in T. spitzbergensis. Stephensen (1935) shows a multi-articulated accessory flagellum and a narrowly tapering gnathopod 1 coxa. Neither author illustrated or described uropod 2. Stephensen (1935) was unsure of his identification and his material may well be a different species. Chevreux (1926) indicates the similarity of T. spitzbergensis to Tryphosella schneideri Stephensen, 1921, which does not have a constricted inner ramus on uropod 2. Until this character is known the species cannot be definitely placed in either Gronella or Tryphosella. Distribution. Arctic, northwest boreal Atlantic.Published as part of Kilgallen, N. M. & Lowry, J. K., 2014, The Tryphosa group (Crustacea: Amphipoda: Lysianassoidea: Lysianassidae: Tryphosinae), pp. 501-545 in Zootaxa 3768 (5) on page 507, DOI: 10.11646/zootaxa.3768.5.1, http://zenodo.org/record/490968
On One Chronological Question of Early Croatian Archaeology (asked by Ljubo Karaman)
No full textOsvrnuvši se na postavljenu tezu o pojavi trojagodnih naušnica kod nas tek u kasno doba Srednjeg vijeka, koju je S. Gunjača utemeljio na skupnom nalazu trojagodnih naušnica i novca Ludovika Anžuvinca (1342.-1382.) u zatvorenoj grobnoj cjelini pri istraživanju nekropole uokolo porušene crkve sv. Mihovila u Brnazama kod Sinja, Lj. Karaman u prvom poglavlju naslovljenom "O vremenu pojave trojagodnih naušnica t. zv. Kijevskog tipa u dalmatinskoj Hrvatskoj" u svom članku "Dva hronološka pitanja starohrvatske arheologije" najprije dovodi u pitanje, a zatim odbacuje tu Gunjačinu tvrdnju. Kao glavni argument za potvrdu svoga mišljenja o pojavi trojagodnih naušnica u ranom srednjem vijeku donosi arhivsku fotografiju, iz fototeke Muzeja hrvatskih starina, na kojoj se uz par ostruga karolinškog tipa, koje on datira u IX. st., u zajedničkoj cjelini nalaze i trojagodne naušnice ukrašene filigranom. Suočen s Karamanovom argumentacijom za koju nije imao adekvatnog odgovora Gunjača više ne ulazi u kronološka pitanja naušnica. Iako je od tada prošlo preko pedeset godina u kojima je arheološka znanost uz nove nalaze evoluirala, začuđuje činjenica da mnogobrojni povijesničari umjetnosti i arheolozi koji se bave tipologijom i kronologijom hrvatskog srednjovjekovnog nakita zaobilaze to Karamanovo stajalište, izbjegavajući taj članak i u njemu postavljene argumente kao da nikada nije ni napisan. No, dok god se ne riješi pitanje koje je tu postavio Karaman, sva domišljanja o kronologiji te vrste nakita znanstveno su manjkava i nedosljedna. Ovaj prilog, posvećen zaslužnom arheologu i profesoru J. Beloševiću, rješava postavljenu Karamanovu argumentaciju.Referring to the hypothesis about the appearance of three-beaded earrings in Croatia only in the late period of the Middle Ages, which Stjepan Gunjača based on the hoard find of three-beaded earrings and coins of the Angevin king Louis I (1342-1382) in a closed grave unit found during excavations of the cemetery surrounding the ruined church of St. Michael at Brnaze near Sinj, Ljubo Karaman in his article "Two chronological questions of Early Croatian archaeology" in the first section on "The period of appearance three beaded earrings of the socalled Kiev type in Dalmatian Croatia" first questioned and then rejected Gunjača’s claim. As the main argument for confirmation of his opinion about the appearance of the three beaded earrings in the early medieval period, he presented a photograph from the archives of the Museum of Croatian Antiquities, where the grave unit included spurs of the Carolingian type that he dated to the 9th century, along with a three-beaded earring decorated with filigree. Faced with Karaman’s argument, for which he had no proper answer, Gunjača did not further enter into discussions about the chronology of these earrings. Although more than fifty years have passed since then, in which the science of archaeology has greatly evolved through new findings, the fact remains that numerous art historians and archaeologists involved in the typology and chronology of the Middle Ages of Croatia ignore this opinion of Karaman. In fact, they avoid mentioning this article by Karaman and the arguments set forth in it as if it had never even been written. However, until the dilemma presented by Karaman is not solved, all conjectures about the chronology of this type of jewelry are scientifically defective and inconsistent. The author of this contribution, dedicated to the meritorious archaeologist and professor J. Belošević, solves the problem of Karaman’s hypothesis, by discovering that the three-beaded earring should be removed from the grave unit on the archival photograph, as it was placed there by chance. In this manner a serious problem in archaeological science has been removed and a more justified dating of medieval three-beaded earrings is made possible
Evaluation of anterior and posterior corneal aberrations in patients with keratoconus
No full textEvaluation of anterior and posterior corneal aberrations in patients with keratoconusPoster DetailsFirst Author: E.AltinkurtTURKEYCo Author(s): O. Muftuoglu S. Karaman Erdur Abstract DetailsPurpose:To evaluate the anterior and posterior corneal aberrations in patients with keratoconus.Setting:The study is made in a tertiary referral center.Methods:100 eyes of 57 patients with clinical keratoconus and 100 eyes of 50 control patients who were refractive surgery candidates were included in this study. All eyes were evaluated before and 6-months after surgery using Placido-Scheimpflug combined topo/tomographer. Visual acuity, keratometry, anterior, posterior, and total corneal aberrations were analyzed.Results:The mean Ksteep was 48.6 ± 4.8 D in keratoconus group, and 43.2 ±2.1 D in control group. The mean anterior corneal total higher order aberration, coma, and spherical aberration were 1.83±1.39 µm, 1.44 ± 0.92 µm, 0.31 ± 0.29 µm, respectively. The mean posterior corneal total higher order aberration, coma, and spherical aberration were 1.04 ± 1.63 µm, 0.36 ± 0.32 µm, 0.16 ± 0.21 µm, respectively. The mean anterior and posterior corneal total higher order aberration, coma, and spherical aberration were significantly higher than those of control groups (p˂0.05). The differences were more prominent in posterior corneal aberrations.Conclusions:Corneal higher order aberrations, particularly posterior corneal aberrations are significantly higher in eyes with keratoconus compared to normal controls
