Cephalothorax dorsoventrally flattened with well-developed marginal membranes; frontal plates with lunules. Genital complex just slightly wider than long (Fig. 24A); abdomen 1-segmented, 1.85 times longer than wide; genital complex about 1.4 times longer than abdomen. Antenna with small, pointed posterior process on proximal segment (Fig. 24B). Post-antennal process with weakly curved tine; associated papillae bisensillate with unusually long sensillae (Fig. 24B). Maxilliped of female with smooth myxal margin. Sternal furca with long, slender, slightly incurved tines (Fig. 24C). Distal exopodal segment of leg 1 with 3 plumose setae on posterior margin; distal spine 1 simple, about same length as spines 2 and 3 (Fig. 24D), each armed with accessory process; seta 4 about twice as long as spines and markedly longer than segment. Leg 2 with fine setules along margins of endopodal segments 1, 2 and 3; outer spines on exopodal segments 1 and 2 lying obliquely across axis of ramus; proximal outer spine on exopodal segment 3 curved and well developed, lying across blunt distal spine (Fig. 24E). Leg 3 with 3-segmented exopod; first exopodal segment bearing small straight outer spine but no inner seta; second segment with outer spine and inner plumose seta; third segment with 3 subequal outer spines, plus 4 plumose setae; endopod 2-segmented; first segment forming velum, and armed with inner seta; distal endopodal segment with swollen lateral margin and bearing 6 plumose setae. Leg 4 uniramous (Fig. 24F), 3-segmented; first and second exopodal segments with I and IV spines, respectively; each spine with pecten on surface of segment adjacent to base. Mean body length of female 3.34 mm, range 3.15 to 3.85 mm (based on 8 specimens). Remarks. One of the most characteristic features of C. chiastos is the form of the outer margin spines on the third exopodal segment of leg 2. Unusually, the proximal spine on this segment is curved and slightly longer than the straight distal spine (Fig. 24E). The significance of this feature in distinguishing C. chiastos from the closely related C. acanthopagri Lin, Ho & Chen, 1994 was emphasized by Ho & Lin (2004). Caligus chrysophrysi is very similar to C. chiastos. Indeed, the differences in body proportions are trivial. When C. chiastos was established, Lin & Ho (2003) presented detailed comparisons with C. acanthopagri Lin, Ho & Chen, 1994 but did not compare their material with C. chrysophrysi. Pillai (1985) only had a single female and presented an incomplete description of C. chrysophrysi, but it agrees with that of C. chiastos in every important respect, including the form of the proximal outer spine on the distal exopodal segment of leg 2, which is as long as the distal spine and curves across its surface, as highlighted by Lin & Ho (2003). It is possible that C. chiastos is a junior synonym of C. chrysophrysi, but the species are maintained as separate here on the basis of female body size: the females of C. chiastos range from 3.15 to 3.85 mm whereas female C. chrysophrysi is only 2.1 mm in length according to Pillai (1985). In addition, the lateral spine on the compound distal exopodal segment of leg 4 reaches well beyond the base of the outermost distal spine in C. chiastos (Fig. 24F) but barely reaches this spine in C. chrysophrysi. Caligus chiastos is a pest of both farmed and cultured marine teleost fishes (Hayward et al. 2008; Venmathi Maran et al., 2009). It was described by Lin & Ho (2003) to accommodate specimens of both sexes collected from the haemulid, Plectorhinchus cinctus (Temminck and Schlegel, 1843) in Taiwanese waters. Lin & Ho (2003) also noted that the female caligid reported as Caligus sp. 1 by Roubal et al. (1983) could also be attributed to this species. Roubal et al. ’s (1983) material was collected from the sparid Pagrus auratus (as Chrysophrys auratus) caught off Coff’s Harbour (NSW) in Australian waters. Ho & Lin (2004) listed three additional hosts, Caranx sexfasciatus Quoy & Gaimard, 1825 (Carangidae), Otolithes ruber (Bloch & Schneider, 1801) (Sciaenidae) and Pelates quadrilineatus (Bloch, 1790) (Terapontidae) from Taiwan, and it has since been reported from cultured Lutjanus johnii (Bloch, 1792) (Lutjanidae) in Malaysia (Venmathi Maran et al., 2009). This species is a known pest of farmed fish in Australian waters, including Argyrosomus japonicus (Temminck & Schlegel, 1843) (Sciaenidae), Seriola lalandi (Carangidae), and Thunnus maccoyii (Scombridae) (Hayward et al. 2007, 2008). In addition, early records of C. elongatus and C. rapax from Australian waters (e.g. Heegaard, 1962; Munday et al., 2003; Nowak, 2004) can also, in all probability, be considered as belonging to C. chiastos (Hayward et al. 2008). In Moreton Bay C. chiastos was found on Abudefduf bengalensis (Pomacentridae), Acanthopagrus australis, Lutjanus fulviflamma, Lagocephalus lunaris (Tetraodontidae), Sillago ciliata (Sillaginidae) and Aetobatus ocellatus (Myliobatidae). Having been reported from at least eleven families of actinopterygian fishes, and now from an elasmobranch, it appears that C. chiastos exhibits relatively low host specificity.Published as part of Boxshall, Geoff, 2018, The sea lice (Copepoda: Caligidae) of Moreton Bay (Queensland, Australia), with descriptions of thirteen new species, pp. 1-172 in Zootaxa 4398 (1) on pages 52-55, DOI: 10.11646/zootaxa.4398.1.1, http://zenodo.org/record/120295

Proximal segment of antenna with short rounded posterior process provided with marginal flange (Fig. 53B). Postantennal process strongly curved; associated papillae bisensillate. Maxillule with slight marginal flange on posterior process (Fig. 53B). Sternal furca with incurved tines; accessory processes present on ventral surface of cephalothorax either side of sternal furca. Distal exopodal segment of leg 1 with 1 minute, unarmed vestigial seta on posterior margin (Fig. 53C), lacking plumose setae; distal spines 2 and 3 each with accessory process; seta 4 about 40% longer than spine 1, shorter than segment. Leg 2 outer spines on first and second exopodal segments aligned obliquely across ramus; proximal outer spine on third segment short, distal outer spine with extensive bilateral membrane (Fig. 53D). Leg 3 with 3-segmented exopod; first segment bearing weakly curved outer spine, lacking inner seta; second with outer spine and inner seta; third with 3 spines and 4 setae: endopod 2-segmented; first segment forming well developed velum, bearing inner seta; compound distal segment with 6 plumose setae.

It was originally recognised as a subspecies of <i>C. pagrosomi</i> by Ho & Lin (2004), but Boxshall & El-Rashidy (2009) subsequently raised this subspecies to species level, as C. <i>schelegeli</i> Ho & Lin. 2004. It is proposed here to amend the spelling of the name: Ho & Lin (2004) spelled the name <i>C. schelegeli</i> in the section heading, but in the legends of figures 121 to 123 in the same work, the name was given as <i>C. schlegeli</i>. Whilst not explicitly stated, the name choosen by Ho & Lin (2003) appears to refer to the name of its “ major ” host <i>Acanthopagrus schlegeli</i> (Bleeker, 1854) (Ho & Lin, 2004) which, in turn, honours the nineteenth Century German biologist Hermann Schlegel. The change to <i>C. schlegeli</i> can be considered a justified emendation.

Caligus dactylus Ho, Lin & Chang 2007
No full textCaligus dactylus Ho, Lin & Chang, 2007 Ho et al. (2007) described C. dactylus as a new species based on material of both sexes collected from Dactyloptena peterseni (Nyström, 1887) landed in Taiwan. They made detailed comparisons between their new species and C. priacanthi Pillai, 1961, but did not compare it with C. dactylopteni Uma Devi & Shyamasundari, 1981 described from material taken from another species of flying gurnard, Dactyloptena orientalis (Cuvier, 1829), caught at Waltair on the coast of India (Uma Devi & Shyamasundari, 1981). The descriptions match in every respect and there are no significant differences between these two species. We therefore propose to treat C. dactylus Ho, Lin & Chang, 2007 as a junior subjective synonym of C. dactylopteni Uma Devi & Shyamasundari, 1981.Published as part of Hayes, Polly, Justine, Jean-Lou & Boxshall, Geoffrey A., 2012, The genus Caligus Müller, 1785 (Copepoda: Siphonostomatoida): two new species from reef associated fishes in New Caledonia, and some nomenclatural problems resolved, pp. 21-39 in Zootaxa 3534 on page 32, DOI: 10.5281/zenodo.21082

Male body length 2.28–2.84 mm. Female genital complex longer than wide, lacking distinct postero-lateral lobes: abdomen 2 -segmented, first segment about 2.0 times longer than second. Male abdomen 2 -segmented; second segment about 1.6 times longer than first. Female antenna with distal claw weakly curved. Post-antennal process curved in both sexes. Additional process present between post-antennal process and base of antenna in female. Posterior process of maxillule with tiny blunt accessory process in male. Sternal furca of female with incurved tines and with small rounded processes on body surface either side of furca. Female maxilliped with smooth myxal margin. Male maxilliped with large, acutely-pointed process on myxal margin, opposing tip of claw. Exopod of leg 1 with seta at inner distal angle shorter than segment but longer than longest of distal spines; posterior margin with single, naked vestigial seta. Outer margin of second endopodal segment of leg 2 ornamented with typical setules. Leg 4 with robust first exopodal segment bearing marginal setule, spine extending beyond base of proximal outer spine of second segment; second segment with distal spines well developed, increasing slightly in length from outer to inner.

The 1961 Kampong Bukit Ho Swee fire and the making of modern Singapore
Get PDFBy 1970, Singapore’s urban landscape was dominated by high-rise blocks of planned public housing built by the People’s Action Party government, signifying the establishment of a high modernist nation-state. A decade earlier, the margins of the City had been dominated by kampongs, home to semi-autonomous communities of low-income Chinese families which freely built, and rebuilt, unauthorised wooden houses. This change was not merely one of housing but belied a more fundamental realignment of state-society relations in the 1960s. Relocated in Housing and Development Board flats, urban kampong families were progressively integrated into the social fabric of the emergent nation-state. This study examines the pivotal role of an event, the great Kampong Bukit Ho Swee fire of 1961, in bringing about this transformation. The redevelopment of the fire site in the aftermath of the calamity brought to completion the British colonial regime’s ‘emergency’ programmes of resettling urban kampong dwellers in planned accommodation, in particular, of building emergency public housing on the sites of major fires in the 1950s. The PAP’s far greater political resolve, and the timing of and state of emergency occasioned by the scale of the 1961 disaster, enabled the government to rehouse the Bukit Ho Swee fire victims in emergency housing in record time. This in turn provided the HDB with a strategic platform for clearing other kampongs and for transforming their residents into model citizens of the nation-state. The 1961 fire’s symbolic usefulness extended into the 1980s and beyond, in sanctioning the PAP’s new housing redevelopment schemes. The official account of the inferno has also become politically useful for the government of today for disciplining a new generation of Singaporeans against taking the nation’s progress for granted. Against these exalted claims of the fire’s role in the Singapore Story, this study also examines the degree of actual change and continuity in the social and economic lives of the people of Bukit Ho Swee after the inferno. In some crucial ways, the residents continued to occupy a marginal place in society while pondering, too, over the unresolved question of the cause of the fire. These continuities of everyday life reflect the ambivalence with which the citizenry regarded the high modernist state in contemporary Singapore

The Relationship Between Pretend Play and Playfulness in Children With Autism Spectrum Disorder
No full textAbstract
Date Presented 3/30/2017
This study explored the relationship between pretend play and playfulness in children with autism spectrum disorder (ASD). Our findings suggest that it is important to assist children with ASD to engage in pretend play, for doing so could promote their internal experience of playfulness.
