Multilocus phylogeny and coalescent species delimitation in Kotschy's gecko, Mediodactylus kotschyi: Hidden diversity and cryptic species
No full textKotschy's Gecko, Mediodactylus kotschyi, is a small gecko native to southeastern Europe and the Levant. It displays great morphological variation with a large number of morphologically recognized subspecies. However, it has been suggested that it constitutes a species complex of several yet unrecognized species. In this study, we used multilocus sequence data (three mitochondrial and three nuclear gene fragments) to estimate the phylogenetic relationships of 174 specimens from 129 sampling localities, covering a substantial part of the distribution range of the species. Our results revealed high genetic diversity of M. kotschyi populations and contributed to our knowledge about the phylogenetic relationships and the estimation of the divergence times between them. Diversification within M. kotschyi began approximately 15 million years ago (Mya) in the Middle Miocene, whereas the diversification within most of the major clades have been occurred in the last 5 Mya. Species delimitation analysis suggests there exists five species within the complex, and we propose to tentatively recognize the following taxa as full species: M. kotschyi (mainland Balkans, most of Aegean islands, and Italy), M. orientalis (Levant, Cyprus, southern Anatolia, and south-eastern Aegean islands), M. danilewskii (Black Sea region and south-western Anatolia), M. bartoni (Crete), and M. oertzeni (southern Dodecanese Islands). This newly recognized diversity underlines the complex biogeographical history of the Eastern Mediterranean region
Shared encounters
No full textEvery day we share encounters with others as we inhabit the space around us. In offering insights and knowledge on this increasingly important topic, this book introduces a range of empirical and theoretical approaches to the study of shared encounters. It highlights the multifaceted nature of collective experience and provides a deeper understanding of the nature and value of shared encounters in everyday life.
Divided into four sections, each section comprises a set of chapters on a different topic and is introduced by a key author in the field who provides an overview of the content. The book itself is introduced by Paul Dourish, who sets the theme of shared encounters in the context of technological and social change over the last fifteen years. The four sections that follow consider the characteristics of shared encounters and describe how they can be supported in different settings: the first section, introduced by Barry Brown, looks at shared experiences. George Roussos, in the second section, presents playful encounters. Malcolm McCulloch introduces the section on spatial settings and – last but not least – Elizabeth Churchill previews the topic of social glue. The individual chapters that accompany each part offer particular perspectives on the main topic and provide detailed insights from the author’s own research background.
A valuable reference for anyone designing ubiquitous media, mobile social software and LBS applications, this volume will also be useful to researchers, students and practitioners in fields ranging from computer science to urban studies

Esta pensadora proveniente del campo de la psicología cognitiva propone un acercamiento al psicoanálisis que conlleva una revisión de conceptos basales, tanto para la psicología cognitiva, que según su entender debe reconocer una deuda intelectual con el psicoanálisis, como para el psicoanálisis, que debe replantearse el sentido de algunos de sus términos basales y la estructura general de su metapsicología. Se presentan en forma sintética los desarrollos teóricos y metodológicos a fin de comprender cuáles son los conceptos fundamentales de la obra de esta autora.The purpose of this paper is to present some key concepts in the works of Wilma Bucci. The author, who comes from the field of Cognitive Psychology, proposes an approach to Psychoanalysis that involves the revision of essential concepts of both Cognitive Psychology – which in her view should acknowledge its intellectual debt to Psychoanalysis – and Psychoanalysis, which should reconsider the sense of some of its fundamental notions as well as the general structure of its metapsychology.

Terrestrial herpetofauna of Limnos and Agios Efstratios (Northern Aegean, Greece), including new species records for Malpolon insignitus (Geoffroy Saint-Hilaire, 1827) and Pelobates syriacus Boettger, 1889
No full textThis article presents herpetofaunal observations from Limnos and Agios Efstratios, two Asia Minor continental shelf islands in the Aegean Sea. Comprehensive surveys over 88 days in total on Limnos, over a period of nine years, consisted mainly of visual encounter surveys and road cruised observations, revealed the presence of three species of amphibians and twelve species of reptiles, including two new species records for the island (Malpolon insignitus and Pelobates syriacus). The results of these surveys provide a clearer understanding of the extant herpetofauna on Limnos and Agios Efstratios and offer discussion on natural history, possible erroneous historical records and preliminary ecological understanding of the herpetofaunal assemblages residing on these islands

Göteborg Natural History Museum, GNM Re. ex. 4942. Leg. Nilson & Andrén 1988. Paratypes. GNM Re. ex. 6823 (six newborn), GNM Re. ex. 6849 (ZIG 146), GNM Re. ex. 6850 (ZIG 147), GNM Re. ex. 6851 (ZIG 142) + GNM ZIG 145. Leg. Nilson & Andrén 1988. Terra typica. Peristeri, Lakmos Mountains in the central Pindos mountain range, 1900 m altitude, Greece (Nilson & Andrén 1988). Morphological Diagnosis. This taxon differs from all other members of V. ursinii – renardi complex by having the following combination of morphological characters (Nilson & Andrén 1988; Nilson & Andrén 2001; Mizsei et al. 2016): small body size (for males a snout to vent length (SVL) max. 40.6 cm, and tail length is 5.4 cm, and for females a SVL max. 44.3 cm, and tail length is 4.1 cm); non-bilineate body ground colour pattern; white or bright brownish-grey ventral colour; no dark spots on labial, lateral and dorsal sides of head except occipital and postorbital stripes; dorsal zigzag pattern tagged with pointed corners at windings, or consisting of a narrow vertebral line only; 45–58 dorsal windings; nasal divided into two plates or united with nasorostralia; rostral as high as broad; 2–8 loreals; 13–20 circumoculars; upper preocular not separated from nasal; 7–20 crown scales; more fragmented parietals; 12–15 supralabials (sum of right and left sides); first three supralabials two times larger than the following ones; third supralabial below orbit; 14–19 sublabials (sum of right and left sides); 3–5 mental scales; early dorsal scale row reduction; 120–129 ventrals for males, 119–133 ventrals for females; lowest number of subcaudals in the complex: 21–29 subcaudals for males, 13–26 subcaudals for females. Molecular Diagnosis. The works of Ferchaud et al. (2012) and Zinenko et al. (2015) showed divergence of Vipera graeca stat. nov. based on mtDNA datasets. Its distinction is supported by phylogenetic position (basal taxon for all other species of the ursinii-renardi complex), time of divergence (the Middle Pliocene) and value of uncorrected pairwise p–distances (4.5% in view of ursinii clade) as is defined by Ferchaud et al. (2012). All our analyses based both on mitochondrial and nuclear loci support these results. Specimens in the study of Ferchaud et al. (2012) originated from Stavros area in the Vardoussia Mts., Greece), but in the present study we used samples from Albania. The specimens used here share the same CYT B and ND4 haplotypes as the previously analysed Greek samples of Ferchaud et al. (2012). A single ND4 haplotype is presented by the southernmost (Stavros area, Vardoussia Mts., Greece) and the northernmost populations (Tomorr Mts., Albania; Mizsei et al. 2016). Therefore, a single haplotype is very likely to be present throughout most of the distribution area of this species. Because the sequence variability of the nDNA regions is, in general, much less variable than mtDNA (Townsend et al. 2008), we could use specimens originated from another locality than the type locality as they represent the same phylogenetic pattern and position. Distribution. The species occurs in the subalpine meadows of the Hellenides mountain system of southern Albania and central Greece (Dimitropoulos 1985; Nilson & Andrén 1988; Nilson & Andrén 2001; Korsós et al. 2008; Mizsei et al. 2016). These localities are Koziakas, Lakmos (Peristeri; type locality), Metsovon, Oiti, Tsouka Karali, Tzoumerka (Athamanika), Tymfristos, Vardoussia (including Stavros area) mountains in Greece, and Dhëmbel, Llofiz, Lunxhërisë, Griba, Nemerçkë (crossborder mountain, called Nemertzika in Greek), Shëndelli, Tomorr and Trebeshinë mountains in Albania. The entire distribution is extremely fragmented and each mountain population is completely isolated by a large matrix of unsuitable habitat for the taxon consisting of deep valleys and plains. Ecology and habitats. A mosaic of open or closed grass and shrub communities formed on limestone characterizes the main habitats of the taxon. Annual mean temperatures are about ~6°C, and the meadows are partially covered by snow until early summer (May-June. South-facing slopes are usually more open and rocky than north-facing slopes. Different species of Festuca, Poa and Sesleria dominate the open grasslands, and characteristic shrubs are Juniperus sabina, Daphne oleoides and Astragalus creticus. Most of the observed vipers were found close to shrubs or stone piles in south-facing habitat patches. The diet of the species consists mainly of Orthoptera (97%) species, of which Stenobothrus rubicundulus, Platycleis sp., Decticus verrucivorus is the most frequent prey (Mizsei et al. in prep.). The abundance of Orthopterans is high from June to September (Lemonnier- Darcemont et al. 2015.). Known predators of the species are Vulpes vulpes, Falco tinnunculus and Circaetus gallicus.Published as part of Mizsei, Edvárd, Jablonski, Daniel, Roussos, Stephanos A., Dimaki, Maria, Ioannidis, Yannis, Nilson, Göran & Nagy, Zoltán T., 2017, Nuclear markers support the mitochondrial phylogeny of Vipera ursinii – renardi complex (Squamata: Viperidae) and species status for the Greek meadow viper, pp. 75-88 in Zootaxa 4227 (1) on page 84, DOI: 10.11646/zootaxa.4227.1.4, http://zenodo.org/record/26638
Design and Development of Sentient Collective Urban Spaces
No full textThis chapter aims to envision design approaches for creating ubiquitous interactive spaces which can empower the users to shape and reshape their living environments. It starts with the discussion of the affordances of networked sentient technologies to facilitate cycles of reflexivity through a comparative case study. Based on this analysis, the author distils key principles for future practices including: incomplete, dynamic architectural program, continuous representation of the user needs, incorporation of user variety and differences, embracing open-endedness, self-organization and spontaneity in use. Following these principles, the author reveals a conceptual design for a sentient space in Ghent as a means to demonstrate action possibilities latent in ubiquitous spaces. In conclusion, the author shares lessons learned and elaborates on future directions.status: Publishe
A new dimensionality estimation tool for multiple-item tests and a new DIF analysis paradigm based on multidimensionality and construct validity
No full textThis thesis is concerned with two critical issues facing the testing industry today: dimensionality analysis and DIF (Differential Item Functioning) analysis. Chapter 1 develops the use of new dimensionally-sensitive proximity measures with Hierarchical Cluster Analysis and DIMTEST to estimate the dimensionality structure of tests. The results of simulation studies and real data analyses indicate that the new tool represents a significant step forward in the ability of dimensionality assessment tools to identify reliably the latent dimensionality structure of a set of items. Chapter 2 of the thesis develops a new DIF analysis paradigm that unifies the substantive and statistical DIF research camps by linking both camps to a theoretically sound and mathematically rigorous multidimensional conceptualization of DIF. The new paradigm is shown to have the potential to improve the understanding of the root causes of DIF through the testing of substantive DIF hypotheses, to reduce Type 1 error through a better understanding of the dimensionality of the matching criterion, and to increase power through the testing of bundles of items with similar content. Two new paradigm-based DIF analysis methods, one of which employed the new dimensionality estimation tool of Chapter 1, were described and applied to real data. The analyses demonstrated that the new paradigm-based methods offered insights that cannot be obtained from the standard one-item-at-a-time DIF analysis.Made available in DSpace on 2011-05-07T14:05:53Z (GMT).
