Praesphaerammina, a new genus of Cenozoic deep-water agglutinated foraminifera from the Carpathian flysch deposits
No full textThe genus Praesphaerammina Kaminski and Filipcscu is newly described based on a revision of the type species Cystammina subgaleata Vasicek 1947. The genus differs from the Holocene genus Sphaerammina Cushman 1910 emend. Loeblich and Tappan 1964, in possessing a less embracing final chamber and in its interio-areal to areal aperture that lacks any tooth. The definition of the subfamily Sphaeramminae is accordingly emended as well. The genus is common in the Eocene of the Carpathian flysch deposits, but the type species Praesphaerammina subgaleata (Vasicek 1947) is also observed in the Caribbean region and West Africa, where it ranges into the Miocene
The response of modern benthic foraminiferal assemblages to water mass properties along the southern shelf of the Marmara Sea.
No full textDiffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Does National Identity have an impact on Gender Equality? A Feminist-Constructivist analysis of Estonia´s identity formation process and its impact on Gender (In-)Equality today
No full textThe shift of mainstream International Relations after the collapse of the Soviet Union as well as societal changes challenged the way we see the world. This research is concerned with the, for the researcher most pressing issue of our social coexistence, (In-)equality. To further narrow down, the author engages with identity formation and the issue of gender in Estonia. After assessing the International Relations relevance of Feminist IR and pointing out Constructivist similarities ontological and epistemological assumptions are presented, where the author shares the Feminist claims of seeing states as the analytical unit in the international system but as a representational conglomeration of a population. Estonia´s transformation process, from a oppressed socialist society to economic liberalization will show a deeper connection to the population´s national identity. The methodological endeavour takes two indexes the Gender Equality Index and the World Value Survey and cross-analyses opinion with reality and finds correlation in the Socialist past influencing the opinion in Gender Equality. The comparative study with Slovenia shows ineffectiveness of Gender quotas and a general slow progress in terms of Gender Equality. Concluding, that the past and the constructed identity against the former Soviet ideology and the constructed national identity has an influence on Gender Equality

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Atypical intraocular migration of Angiostronglus vasorum
No full textINTRODUCTION. Angiostrongylus vasorum is a nematode which usually inhabitsthe pulmonary arteries and right ventricle of wild and domestic canids (Morgan et al., 2005 Trends Parasitol. 21: 49-51). Clinical manifestations vary from insidious and non-specific signs (mostly respiratory and neurological manifestations) to fatal cardiopulmonary insufficiency (Ferdushy et al., 2010 Parasitol Res. 107: 765-71). In extremely rare cases, larvae can migrate through the host’s body and reach atypical tissues such as the anterior chamber of the eye, but the mechanism of migration is still unclear (Colella et al., 2016 Parasit Vectors. 9: 161). This report describes the case of two intraocular A. vasorum specimens in an 18-months old dog living in the countryside of Terni, Central Italy.
MATERIALS AND METHODS. The patient was referred for an ophthalmological examination due to the presence of two motile parasites in the anterior chamber of one eye. The medical historyshowed that hehad several episodes of recurrent cough in the past. Physical and imaging (thoracic X-ray and ultrasound) examinations were carried out, along with a complete hematobiochemical analysis and modified Knott test. The intraocular parasites were surgically removed and preserved in 70% ethanol for morphological and biomolecular identification. Serum and aqueous humor were tested forantigens of Dirofilaria immitis (SNAP 4DX Plus, IDEXX, Westbrook, US) and A. vasorum (AngioDetect, IDEXX, Westbrook, US). A stool sample has been examined using the Baermann’s method.
RESULTS AND CONCLUSIONS. The intraocular parasites where morphologically consistent with metastrongylid and identified by PCR as A. vasorum. Both serum and aqueous humor yielded positive for AngioDetect test, and larvae of A. vasorum were retrieved at the Baermann’stest. All tests for D. immitis were negative. Thoracic X-ray and ultrasound showed findings compatible with angiostrongylosis, i.e. areas of subpleural lung consolidation. This clinical case demonstrates the importance of including A. vasorum in the differential diagnosis of canine ocular diseases. Furthermore, an update of the current epidemiological distribution of A. vasorum in Italy would be of great help for local vets towards appropriate diagnostic, prevention, and treatment approaches for angiostrongylosis
