Comparative analyses of caste, sex, and developmental stage‐specific transcriptomes in two Temnothorax ants
2020
Abstract Social insects dominate arthropod communities worldwide due to cooperation and division of labor in their societies. This, however, makes them vulnerable to exploitation by social parasites, such as slave‐making ants. Slave‐making ant workers pillage brood from neighboring nests of related host ant species. After emergence, host workers take over all nonreproductive colony tasks, whereas slavemakers have lost the ability to care for themselves and their offspring. Here, we compared transcriptomes of different developmental stages (larvae, pupae, and adults), castes (queens and workers), and sexes of two related ant species, the slavemaker Temnothorax americanus and its host Temnoth…
Foreign Language learning and teaching Enjoyment: Teachers’ Perspectives
2019
Aim. The primary objective of the present study was to investigate the level of Foreign Language learning Enjoyment and Foreign Language teaching Enjoyment experienced by foreign language teachers in Poland. The secondary aim of the study was to investigate the sources of FLE from the perspective of FL teachers.
 Methods. The informants of the study were Polish educators teaching foreign languages at different educational levels (from primary to tertiary education). To compute the obtained quantitative data, the statistical program STATISTICA was used. Standard descriptive and inferential statistics were used to report means, median and standard deviation for sociodemographic and base…
Between ideologies and realities: Multilingual competence in a languagised world
2016
AbstractRecent developments in sociolinguistics and applied linguistics have put emphasis on the contrast between ideologies of distinct ‘languages’ and the multifaceted reality of linguistic practices. This article argues that recent usage-based reconceptualisations of the notions of competence and repertoire can help paint a more complex picture of the relationship between monolingual ‘ideologies’ and diverse linguistic ‘realities’. Drawing on data from interviews with highly proficient adult speakers of Finnish as a second language, I explore some aspects of how speakers’ competence can be understood as shaped by language use, and what role linguistic ideologies, social expectations and …
SAMSLAM: Simulated Annealing Monocular SLAM
2013
This paper proposes a novel monocular SLAM approach. For a triplet of successive keyframes, the approach inteleaves the registration of the three 3D maps associated to each image pair in the triplet and the refinement of the corresponding poses, by progressively limiting the allowable reprojection error according to a simulated annealing scheme. This approach computes only local overlapping maps of almost constant size, thus avoiding problems of 3D map growth. It does not require global optimization, loop closure and back-correction of the poses.
MOBILE MAPPING FOR CULTURAL HERITAGE: THE SURVEY OF THE COMPLEX OF ST. JOHN OF THE HERMITS IN PALERMO (ITALY)
2023
Abstract. During the 11th and 12th century, the Arab-Norman architectural style characterized the most beautiful and important Cultural Heritage buildings in Sicily, and especially in Palermo (Italy). The relevance of these monuments is highlighted by their inclusion in the UNESCO World Heritage Sites List in 2015. For many years, the University of Palermo has been studying and documenting several Arab-Norman cultural assets, and in particular, the complex of St. John of the Hermits in Palermo (Italy). A first detailed 3D survey of the main structures of this complex was carried out using a terrestrial laser scanner while the 3D survey of the entire complex was made using a Mobile Mapping S…
Integrating the Real and Virtual World for Academic Language Education in Second Life
2013
This chapter focuses on a Second Language Acquisition (SLA) study conducted in virtual worlds that could help teachers in terms of knowledge about acquisition processes, in which technology is integration between formal and non formal education. The research comprises of two studies strongly focused on the development of Italian oral language proficiency. It was held within Second Life® (SL™)1 in order to explore the affordances of public spaces to enhance Intercultural Communicative Competence (ICC)2 and to stimulate the oral production through learner’s engagement. Since 2007, a new pilot project, Café Italia, was developed by Carmela Dell’Aria (aka Misy Ferraris) in Second Life®. Startin…
Further evidence that D90A-SOD1 mutation is recessively inherited in ALS patients in Italy.
2008
Mutations in the Cu/Zn superoxide dismutase 1 (SOD1) gene have been reported to cause adult-onset autosomal dominant amyotrophic lateral sclerosis (FALS). In sporadic cases (SALS), de novo mutations in the SOD1 gene have occasionally been observed. All the SOD1 mutations are autosomal dominantly inherited with the exception of D90A. To date, in Italy, only two sporadic ALS cases carrying the D90A mutation have been reported in a homozygous state. We investigated for the presence of this mutation in 169 unrelated ALS patients from southern Italy. The genetic analysis revealed three ALS patients (1.8%) with mild phenotype carrying the homozygous D90A mutation.
Granulomatous slack skin: report of a case associated with Hodgkin's disease and a review of the literature.
1994
We report a case of granulomatous slack skin (GSS) associated with Hodgkin's disease, and review the literature on this entity. GSS, a variant of cutaneous T-cell lymphoma, clinically presents with erythematous patches in the flexures, which gradually transform into bulky, pendulous areas of skin. Histology shows an elastolytic granulomatous infiltrate, with atypical lymphoid cells, and occasional epidermotropism. As far as we are aware, 10 cases of GSS, including our patient, have been reported in detail. The male:female ratio of these cases is 9:1, and the age range 15-51 years. Five cases were associated with Hodgkin's disease, one with small lymphocytic lymphoma, and one developed cutan…
Viktor Sklovskij na Belomorkanale: literator kak razvedcik
2017
Viktor Shklovskii actively participated in the infamous collective volume about the White Sea-Baltic canal (1934). He did not, however, take part in the writers’ excursion organized by the OGPU: he had travelled to the lager alone well before that, looking for his convicted brother. This is, at least, the version the writer was trying to spread in his senior years, clearly trying to diminish his responsibility for a book glorifying slave labour in the Soviet camps in the eyes of the progressive intelligentsia. In the post-Stalin years, a new role-model for writers emerged, offering an alternative to the previous forced choice between “general” and “martyr”: we could call this third option t…
