Immigrants, markets and policies in Southern Europe. The making of an immigration model?
No full textThe authors skilfully synthesise the immense research and new findings pertaining to four countries – Italy, Greece, Spain and Portugal (Arango, Bonifazi, Finotelli, Peixoto, Sabino, Strozza & Triandafyllidou 2009). They refer to earlier comparative analyses of immigration experiences in Southern European countries with the intention of testing their validity and updating them. In the analysis, They focus on the phenomenon of irregular migration, the mechanisms of migrant workers’ insertion in the labour market and migration policy responses. Special attention is paid to regularisation policies, executed – typical for Southern countries – ex post, as well as to their effectiveness and social costs. Through cross-country analysis, the authors scrupulously examine various aspects of migration related experiences, tracking signs of both regional homogeneity and diversity. Despite the differences with regard to timing, quantity and types of migrant flows or to policy tools, ultimately, they seem to be convinced that a ‘Southern model’ does exist. They stress, however, that the model is dynamic because with time it acquires ever-new dimensions and meanings and includes new social frameworks and new policy instruments
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
Austrodecus childi Arango, 2003, new species
No full textAustrodecus childi new species (figure 5) Type material. Holotype W, Pandora Reef, 3–6 m, among rubble and algae, 15 July 1999. Paratypes two juveniles, same locality, 19 April 2000. Other material. Townsville Port, piling scrapings, 3 m,?/ 2001, 2 X. Diagnosis. Trunk with four dorsomedian tubercles, moderately tall, two long slender spines distally in all first coxae, one dorsodistal in femur, one long slender spine distally on femur and tibiae. Description. Trunk length 0.9 mm, width 0.42 mm, fully segmented, lines of segmentation distinct, granulate surface, crurigers distanced by less than half their diameter, each segment with a dorsomedian slender tubercle half the length of the ocular tubercle, abdomen horizontal, somewhat curved downwards, with dorsal row of small granules. Ocular tubercle very tall, pointing obliquely towards the front, with rounded tip housing dark pigmented eyes (height 0.44 mm, width base 0.1 mm). Proboscis long, thin, strongly downcurved, joined to a basal stalk, otherwise typical pipette-like, about 25 annulations (length 0.7 mm). Palps slightly longer than proboscis, with six segments, all with small granules, segmentation line between second and third not clear, third segment the longest, with two dorsal tubercles, one at midpoint, another distally, ventral setae on fourth segment (total length palp 0.9 mm; 0.1–0.16–0.32–0.8–0.16–0.8), gland openings visible on second palp segment. Ovigers not found in any of the specimens. Legs not remarkably long, femur the longest segment, tibiae subequal, first coxa with two prominent, tubular distal spines forming a V-shape, longer than the dorsomedian tubercles, small dorsal tubular spine on third coxa and femur, two long simple spines on femur, one distally, other ventrally; both tibiae with a long distal spine; propodus curved, with no heel, feeble sole spines; main claw long and robust. Auxiliaries lacking (total length third leg 1.76; 0.1–0.12–0.1–0.4–0.3–0.25–0.07–0.32–0.18). Etymology. This species is dedicated to Dr C. Allan Child, for his enormous contribution to the knowledge of sea spiders from all around the world, especially of those from remote locations. Distribution. Only known from the inshore Pandora Reef and Townsville Port. Remarks. This previously unknown species fits into the gordonae -section (Stock, 1957), appearing related to A. stocki Child, 1988 from the Indo-Pacific, A. palauense Child, 1983 from the Palau Islands and A. staplesi Stock found in New South Wales (Stock, 1990). They all have a similar armature in the distal segments of palps, have mid- to low median dorsal tubercles and are found in shallow tropical waters. Austrodecus childi differs from A. stocki in the lack of distal femoral spur (instead it has a mid-dorsal long tubercle not present in any other species), the shape of the trunk is not as compact as A. staplesi nor as elongate as A. palauense, the dorsal spurs in first coxae are longer than in any of the other species. Remarkably, males of this species do not show signs of ovigers. This absence has been attributed only to deep-sea species grouped in the subgenus Tubidecus (Stock, 1991).Published as part of Arango, Claudia P., 2003, Sea spiders (Pycnogonida, Arthropoda) from the Great Barrier Reef, Australia: new species, new records and ecological annotations, pp. 2723-2772 in Journal of Natural History 37 (22) on pages 2734-2737, DOI: 10.1080/0022293021015877
Anoplodactylus concavicollis Arango, 2003, new species
No full textAnoplodactylus concavicollis new species (figure 9) Type material. Holotype X, GBR, Orpheus Island, Pioneer Bay, reef flat, in Galaxaura rugosa (Ellis and Solander), 27 July 1998. Two paratypes X, juvenile, same locality as holotype. Other material. Same locality as holotype, 24 November 1998, five W, 17 X; 14 April 2000 one X. Great Palm Island, Cannon Bay, reef flat 2 m, in Laurencia sp. and G. rugosa, 28 November 1998, one W. Picnic Bay, intertidal, found in Laurencia sp. attached to rock, 3 October 1998, one W with eggs, one X. Turtle Bay, intertidal in C. prolifera, 27 March 1997, three W, four X, three juveniles (coll. Otto); 12 July 1999, one W; 4 May 2000, two W, two X; 1 July 2000, one X. Diagnosis. One of the tiniest pycnogonids, leg span 2.5 mm, sides of the neck concave. Description. Trunk length 0.64 mm, width 0.49 mm; ovoid in dorsal outline, glabrous, neck short, with concave sides, anterior pair of crurigers extends slightly forward beyond the oviger bases. Crurigers crowded together, armed with low rounded distal tubercles, ocular tubercle moderately tall, with large well-pigmented eyes and a low apical cone; abdomen typical (length 0.2 mm), erect, as tall as the ocular tubercle. Proboscis short, cylindrical, slightly tapering distally, carrying the mouth horizontally (length 0.3 mm). Chelifore scape one-segmented, glabrous, chelifores touching each other. Ovigers with six segments, third segment longest, last segment pointed, twice as long as wide. Legs short, with swellings, second coxae of fourth pair of legs with ventral genital spurs in males, a spine distally in femur and tibiae, cement gland a mid-dorsal tube. Females with swollen femora and smoother appearance, with same pattern of spination as males, propodus large, curved, strong heel, two heel spines, main claw more than three-quarters the length of the propodus, no auxiliary claws visible (total length third leg= 1.95 mm; 0.1–0.25–0.1–0.4–0.3–0.2–0.1–0.3–0.2). Etymology. A compound name that refers to the unusually concave sides of the neck (Latin collis meaning neck) seen in dorsal view. Distribution. This species is only known from localities near Townsville and coral reefs in the central section of the GBR. Remarks. Anoplodactylus concavicollis is one of the tiniest sea spiders known. Given its relatively wide distribution in the area studied, it is expected the species had been overlooked previously due to its small size. The species is similar to A. viridintestinalis Cole, 1904 and also A. crassus Child, 1988. These share the ovoid trunk and small robust appearance with crowded crurigers, short proboscis and short legs but the characteristic shape of the neck is not found in any other species. Specimens from Picnic Bay Magnetic Island had a more greenish coloration.Published as part of Arango, Claudia P., 2003, Sea spiders (Pycnogonida, Arthropoda) from the Great Barrier Reef, Australia: new species, new records and ecological annotations, pp. 2723-2772 in Journal of Natural History 37 (22) on pages 2748-2750, DOI: 10.1080/0022293021015877

Paranymphon bifilarium Arango, 2009, n. sp.
No full textParanymphon bifilarium n. sp. (Figures 6, 8 C) Holotype: AM P72806, 1 male with eggs and protonymphs. 9 December 2005, Ningaloo South, CSIRO station 141-142, collected with beam trawl from 22.0743 °S 113.8140 °E to 22.0784 °S 113.8130 °E, soft bottom, 102 m. Diagnosis: Trunk unsegmented, cephalon with a long, thin, curved tubercle dorsally at base of chelifores; lateral processes long, highly adorned, each lateral process armed with a long, curved, filiform dorsal spur and with 3 to 4 triangular projections on both sides each tipped with a seta; first coxae follow same pattern with two long spurs dorsodistally. Ocular tubercle very tall, eyes visible, slightly pigmented. Auxiliary claws present, nearly half the length of main claw. Description: Body of moderate size, trunk not segmented, dorsum smooth, lateral processes long, separated by V-shaped intervals, maximum distance twice their diameter, each with a long, thread-like dorsal spur (shorter on the last pair) and two to four lateral projections each side (Fig. 6 A; 8 C). Ocular tubercle tall, height about seven times the diameter at base, eyes at round tip (Fig. 6 H). Abdomen as tall as ocular tubercle but heavier, pointing obliquely upward. Proboscis almost cylindrical, slightly inflated at distal half, truncate tip. Scape 1 -segmented, with few distal setae; chelae slender, with long, curved fingers, tips crossing; 30 and 24 regular, thin teeth on movable and immovable finger respectively (Fig. 6 I). Palp 7 -segmented; second segment longest, with two distal setae, segments 3–6 subequal, with few setae, 7 th segment very small, tipped with two long setae (Fig. 6 G). Oviger ten-segmented, fifth segment longest, with bracelets of eggs attached; strigilis with simple spines in the formula 4: 2: 2: 2; terminal claw not much longer than distal segment, with seven denticulations (Fig. 6 E, F). Legs slender, smooth except for proximal coxae, first coxa with three lateral projections on each side, all tipped by a seta as in lateral processes; third coxa the shortest, femur as long as first tibia (Fig. 6 B), cement glands open through seven pores ventrally on proximal half of femur (Fig. 6 D); second tibia longest segment; tarsus very short, slightly shorter than main claw; tarsus + propodus + claw shorter than tibia 2; propodus straight with few internal setae; auxiliary claws nearly half length of main claw (Fig. 6 C). Measurements (in mm): Trunk length = 2.14; trunk width (across second pair of lateral processes) = 1.85, proboscis = 0.75, ocular tubercle = 1.1, abdomen = 1.07, palp segment 1 (p 1) = 0.07, p 2 = 0.38, p 3 = 0.15, p 4 = 0.06, p 5 = 0.06, p 6 = 0.045, p 7 = 0.03; oviger segment 1 (o 1) = 0.18, o 2 = 0.18, o 3 = 0.18, o 4 = 0.61, o 5 = 1.07, o 6 = 0.18, o 7 = 0.12, o 8 = 0.1, o 9 = 0.09, o 10 = 0.09; coxa 1 = 0.5, coxa 2 = 0.53, coxa 3 = 0.44, femur = 1.44, tibia 1 = 1.41, tibia 2 = 1.52, tarsus = 0.14, propodus = 0.4, main claw = 0.2, auxiliary claw = 0.11. Etymology: The species name relates to the presence of two (lat. bis = twice) thread-like tubercles on the lateral processes, instead of one as in P. filarium from the Caribbean. Remarks: This is the first record of the genus Paranymphon in the southern hemisphere. Three species had been previously recorded: P. s p i n o s u m (Caullery 1896), P. filarium Stock 1986 and P. magnidigitatum Hong & Kim 1987 from the Atlantic and Mediterranean (Hedgpeth 1948; Nogueira 1956; Stock 1966; Stock 1978; 1978) North Pacific (Hong & Kim 1987; Nakamura & Child 1991) and the Caribbean (Stock 1986) respectively. This specimen from Western Australia shares the presence of long filiform spurs with P. filarium, also the tall ocular tubercle and abdomen and the proportions of the leg segments, but the prominent lateral projections on the crurigers, the extremely short tarsus and the auxiliary claws are not found in any of the other three species known. This record of Paranymphon suggests the genus could have a much wider distribution, but the patterns of colonization remain uncertain, as for most sea spiders.Published as part of Arango, Claudia P., 2009, New species and new records of sea spiders (Arthropoda: Pycnogonida) from deep waters in Western Australia, pp. 1-20 in Zootaxa 1977 on pages 13-15, DOI: 10.5281/zenodo.18519
La violencia en la poesía de José Manuel Arango
No full textThis paper presents the poet José Manuel Arango and his poetry from how are the images of violence in his work. His poetry deals with recreating life in the city from the drama, confinement, loneliness, death, very different from the idyllic vision of the thematic field, because in this area the leisure life yearns evoked field, longs wistfully.Este ensayo presenta al poeta José Manuel Arango y a su poesía, desde cómo son las imágenes de la violencia en su obra. Su poesía se ocupa de recrear la vida en la ciudad desde el drama, el encierro, la soledad, la muerte, temáticas muy diferentes a la visión idílica del campo, pues en este espacio se añora la vida tranquila y apacible, el campo se evoca, se añora con nostalgia
