Type species. Arcithelphusa cochleariformis Pati & Sudha Devi, 2015, by original designation; gender feminine. Diagnosis [emended from Pati & Sudha Devi (2015a)]. Carapace ovate, broader than long (cw/cl = 1.2–1.4), relatively deep (ch/cw = 0.6–0.7); dorsal surface arched, almost smooth; anterolateral margin lacking distinct serrations; front strongly deflexed, with narrow frontal margin (fw/cw = 0.25); epigastric cristae only visible as 2 low, broad, oval protuberances; postorbital cristae indistinct; external orbital angle indistinct; epibranchial tooth indistinct; branchial regions highly inflated; cervical grooves relatively shallow, not reaching beyond level of postorbital cristae; frontal median triangle incomplete, lateral margins indiscernible; epistome posterior margin with triangular median lobe and sinuous lateral lobes (Figs. 2A, B, D, E, 4A, B, D, E). Third maxilliped exopod longer than ischium, lacking flagellum or with relatively short flagellum, ca. 0.5× width of merus (Fig. 3B, N). Chelipeds relatively smooth (Figs. 2 A–F, 4A–F). Ambulatory legs slender, long (Figs. 2 A–F, 4A–F). Suture between male thoracic sternites s2/s3 shallow or deep, broad, not reaching edge of sternum; suture between male thoracic sternites s3/s4 deep, broad, reaching edge of sternum (Figs. 2C, F, 3C, 4C). Pleonal locking mechanism with low, anteriorly directed tubercles on each antero-submedial part of sternite 5 (Fig. 3I). Male sternopleonal cavity long, reaching imaginary line joining medial part of cheliped coxae (Figs. 2C, F, 4C). Male pleon narrowly triangular, with concave lateral margins; pleonal somite 6 trapezoidal, broader than long, with gently convex lateral margins (Figs. 2C, F, 3D, 4C). Male telson narrow, with strongly concave lateral margins; apex rounded (Figs. 2C, F, 3D, 4C). G1 relatively stout, with large flexible zone, tip not reaching pleonal locking structure; terminal segment relatively short, ca. 0.3–0.4× length of subterminal segment, medial portion distinctly curved outwards, dorsal flap absent or low, broad; subterminal segment relatively stout, with strongly convex outer margin at basal half (Fig. 3 E–G, I, J, O). G2 short, ca. 0.6–0.7× length of G1; distal segment very short, ca. 0.2× length of basal segment (Fig. 3H, K, P). Remarks. Among the Indian genera of gecarcinucid crabs, Arcithelphusa is most close to Cylindrotelphusa in carapace morphology and gonopod structures (see Pati & Sudha Devi 2015a; Pati et al. 2017). Both the genera can be distinguished from other Indian gecarcinucid genera mainly by the presence of a relatively deep carapace (ch/cw = 0.5–0.7), a narrow frontal margin (ca. 0.25 times the carapace width), an incomplete frontal median triangle, and a short G2 distal segment (ca. 0.2–0.3 times the length of the basal segment) (Figs. 2B, E, 3H, K, P, 4B, E; see Bahir & Yeo 2007: figs. 4D, 5B; Pati et al. 2017: figs. 11b, 12d, 13b, 14d). Other major characters common to both are their strongly convex dorsal surface, the highly inflated branchial regions, the prominent and triangular median lobe on the epistome posterior margin, a narrowly triangular male pleon, and a short G2 (Figs. 2 A–F, 3D, E, H, J, K, O, P, 4A–E; see Bahir & Yeo 2007: figs. 4A, D, 5A–C; Pati et al. 2017: figs. 11a–c, h, 12a, d, 13a–c, h, 14a, d). While they share many features of the carapace and gonopods, the flagellum on the exopod of the third maxilliped shows considerable variations. The flagellum on the third maxilliped exopod is altogether absent in A. cochleariformis (Fig. 3N) whereas it is distinct but short in A. tumpikkai sp. nov., reaching nearly half the merus width (Fig. 3B). On the other hand, all the species of Cylindrotelphusa have a well-developed and relatively long flagellum on the third maxilliped exopod, which reaches up to 0.6–0.7 times the merus width (see Pati et al. 2017: figs. 11i, 13i). The variations in the length of the flagellum on the third maxilliped exopod could be associated with the ecological requirements of each species of Arcithelphusa and Cylindrotelphusa. According to Cumberlidge (1999), the presence of a long flagellum on the third maxilliped exopod of a crab is a plesiomorphic state, and the absence of the said flagellum is an apomorphic state, which is common in air-breathing crabs and mostly associated with the adaptations of the respiratory system by the relatively terrestrial species of freshwater crabs (see Ng & Shokita 1995). Cumberlidge (1999) also noted that this character is useful to distinguish some genera of the West African crabs. The presence or absence of a flagellum on the third maxilliped exopod, however, is not a reliable character to exclusively define Arcithelphusa and Cylindrotelphusa because the condition of the flagellum varies considerably among their species depending upon the habitat preferences. Huang (2018) recently found that some crab genera are strikingly similar in external morphology, and the use of the G1 characters alone could be problematic to define them. In these situations, he suggested using a combination of characters that are apparently under less environmental selective pressure, such as male pleon, G1, and female vulvae. Furthermore, a molecular study has now become necessary to support morphological data (see Shih et al. 2016; Huang 2018). Currently, no molecular data is available for Arcithelphusa and Cylindrotelphusa, and the female vulvae were not described for all the species. Their male pleon is quite similar in morphology. On the contrary, the G1 structure is a reliable character to set them apart. While the generic treatment of Arcithelphusa needs investigation based on morphological and molecular data, we still continue to recognize the genus and provide here an emended diagnosis to accommodate both A. cochleariformis and A. tumpikkai sp. nov. Arcithelphusa can be now distinguished from Cylindrotelphusa by the following suite of characters: the anterolateral margins of the carapace lack distinct serrations (Figs. 2A, D, 4A, D) (vs. with distinct serrations; see Bahir & Yeo 2007: fig. 5A; Pati et al. 2017: figs. 11a, 13a); the third maxilliped exopod lacks a flagellum (Fig. 3N) or with a short flagellum that reaches half the merus width (Fig. 3B) (vs. with a well-developed flagellum that reaches beyond half the merus width; see Pati et al. 2017: figs. 11i, 13i); the chelipeds are relatively smooth (Figs. 2 A–F, 4A–F) (vs. rugose; see Bahir & Yeo 2007: fig. 5A–C; Pati et al. 2017: figs. 11a, c, d, 13a, c, d); the G1 is relatively stout with a large flexible zone (Fig. 3 E–G, J, O) (vs. relatively slender with a reduced flexible zone; see Bahir & Yeo 2007: fig. 4A–C; Pati et al. 2017: figs. 12a–c, 14a–c); the G1 terminal segment is relatively short, ca. 0.3–0.4 times the length of the subterminal segment (Fig. 3E, J, O) (vs. relatively long, ca. 0.4–0.6 times the length of the subterminal segment; see Bahir & Yeo 2007: fig. 4A; Pati et al. 2017: figs. 12a, 14a); the G1 subterminal segment is relatively stout, with a strongly convex outer margin at the basal half (Fig. 3E, F, J, O) (vs. relatively slender, with a straight to gently convex outer margin at the basal half; see Bahir & Yeo 2007: fig. 4A, B; Pati et al. 2017: figs. 12a, c, 14a, c). Distribution. The genus is endemic to the Western Ghats of India and known only from Wayanad district of Kerala (Fig. 1).Published as part of Pati, S. K., Sujila, P. S. & Devi, A. R.

Rappresentazioni della storia della psicologia sociale in Europa e Nord America attraverso l'analisi della produzione scientifica: European Journal of Social Psychology e Journal of Personality and Social Psychology
No full textIf we consider a discipline as a historical product of the dynamics that exist between institutions, scientific communities and their practices (Danziger, 1995), scientific production, as a product of these dynamics, can be considered crucial to outline its history. Studying the history of a discipline starting from its scientific production means understanding how it is built around a specific community, since it contains its theories, methods and fields of application (Trevisani & Tuzzi, 2015, 2018). The aim of the present dissertation is to offer a representation of the history of social psychology in two communities or centres (cf. Danziger, 1996), European and North American, which are historically linked and at the core of debated issues in the field. Thus, we started from the study of the temporal evolution of contents in two central journals in their respective contexts: European Journal of Social Psychology and Journal of Personality and Social Psychology. In particular, we intend: 1) to offer a reflection on the contribution of the methods used to portray a history of a discipline, 2) to identify the direction of publications by highlighting hegemonic or marginal perspectives and methods and 3) to contribute to a reflection on the discipline itself. Since these journals convey the contents of the articles through keywords, all the titles and the abstracts of the two journals have been collected from their foundation (1971 and 1965 respectively) until the last issue of 2016. By means of a (lexical) correspondence analysis (SPAD software), the existence of a latent temporal pattern in keywords' occurrences has been explored. An overview of the words that characterised each year in each corpus is presented to observe and compare debated themes, processes, and methods covered by the two journals throughout the years. Furthermore, the main debated topics (that are clusters of words with a common meaning) by the journals and their temporal trajectories have been identified and compared by means of Reinert's method (1986) (IRaMuTeQ and R software) and Latent Dirichlet Allocation (Blei, Ng, & Jordan, 2003) (implemented in the R environment). The individual trajectories of the keywords were then tracked and grouped together based on their temporal pattern (Functional Data Analysis and Curve Clustering) in order to identify their "life cycle" (Trevisani & Tuzzi, 2015; 2018). Finally, some interviews with social psychologists were carried out to discuss some of the outcomes of the analyses, they were also invited to highlight methods and perspectives that might remain marginal to the field and to discuss on the overall history and development of the discipline. The results from all the moments of data collection and analysis were discussed a) by making a comparison between the journals and the literature, b) with respect to the methods used and c) reflecting on some questions posed in the beginning of this project - or that have emerged during the course of the work -considered relevant to fully explore the influence the history of the discipline to the field of Social Psychology
1D ZnO nano-assemblies by Plasma-CVD as chemical sensors for flammable toxic and gases
No full textIn this work, 1D ZnO nano-assemblies were prepared on Al(2)O(3) substrates by plasma enhanced-chemical vapor deposition (PE-CVD), and characterized in their morphology and chemical composition by field emission-scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDXS) and X-ray photoelectron spectroscopy (XPS). For the first time, the sensing performances of PE-CVD ZnO nanosystems were tested in the detection of toxic/combustible gases (CO, H(2) and CH(4)), revealing very good responses already at moderate working temperatures. In particular, carbon monoxide and hydrogen detection was possible already at 100 degrees C. whereas methane sensing required a minimum temperature of 200 degrees C. The performances of the present ZnO nanosystems, that make them attractive candidates for technological applications, are presented and discussed in terms of their unique and controllable morphological organization.

We now report similar measurements of air- and -broadening and shifts for the two laser bands, plus new determinations of self-broadening and shifts in the laser bands. These results were obtained from simultaneous analysis of 30 long-path absorption spectra using a multispectrum . In addition to the 10 spectra of air-and -broadened natural analyzed previously, we have included 20 new spectra recorded at room temperature and resolution using the McMath-Pierce FTS. These additional spectra include two low pressure, four air-broadened and four -broadened spectra obtained with a -enriched sample and 10 self-broadened spectra obtained with a high purity natural sample. The self-broadened spectra were recorded with pathlengths of 73, 97, 193 and 433 m and pressures varying between 3 Torr and 400 Torr. The spectra were obtained with a pathlength of 84 m with sample pressures < 4 Torr for the low-pressure spectra and from 100 to 500 Torr for the air- and -broadened mixtures. By combining the spectra of and in the same fit we were able to obtain a consistent set of line parameters for both molecules. The results obtained for the and laser bands will be compared with each other, with the values in the HITRAN , and with available values reported in the literature

As in our previous effort, the spectrometer was set up in double-pass to cover the region at resolution. The ozone samples were contained in a glass cell having crossed IR transmitting and UV transmitting paths approximateley 10 cm in each direction. A 254 nm UV-absorption monitor of the same design as Pickett et al. was used to measure the ozone partial pressures, which were kept at approximately 0.3 to 0.5 Torr to prevent the appearance of saturated lines in any region of the band. Four spectra, for which the ozone partial pressure varied by 1.0 percent during the recording time, were selected for anaylysis. Using our multispectrum nonlinear least-squares procedure, we have fit these spectra simultaneously to determine intensities for numerous lines in both the and branches of the fundamental band. These results will be compared with other recent and with the values on the 1992 HITRAN compilation
