Laevimon Yeo & Ng, 2005, new genus
No full textLaevimon, new genus Type species. Laevimon kottelati, new species, by present designation. Diagnosis. Carapace distinctly transverse, high; dorsal surface strongly convex longitudinally and transversely; smooth; grooves weak to indistinct; regions poorly defined; epigastric cristae very weak, indistinct, confluent with postorbital cristae; postorbital cristae indistinct, rounded; antennular fossae slitlike; external orbital angle acutely triangular, separated from epibranchial tooth by distinct, rounded cleft; epibranchial tooth distinct, very low, rounded; anterolateral margin distinctly convex, entire, very weakly cristate; median tooth of posterior margin of epistome low, lateral and outer parts forming continuous sinuous margin, with lateral part convex and outer part gently concave. Ischium of third maxilliped broadly rectangular; exopod reaching beyond upper edge of ischium, with well developed flagellum subequal to or exceeding width of merus. Chelipeds distinctly unequal. Ambulatory legs moderately long, with long, slender dactyli. Suture between thoracic sternites 3 and 4 demarcated by strong ridge; abdominal cavity reaching imaginary line joining median points of coxae of chelipeds. Male abdomen narrowly triangular. G 1 terminal segment about 0.3 times length of subterminal segment, subcylindrical, straight, tip truncate with inner distal angle produced as sharp, narrow projection, proximal part with narrow, humplike, dorsal flap; subterminal segment relatively slender. G 2 with distal segment longer than half of basal segment. Etymology. The genus name is derived from laevis, Latin for smooth or polished, in arbitrary combination with the genus name, Potamon, in allusion to the carapace form of the genus. The gender is neuter. Remarks. Laevimon, new genus, is morphologically closest to Hainanpotamon Dai, 1995, owing to its high, swollen and smooth carapace; long exopod flagellum of third maxilliped; long, slender ambulatory dactyli; and slender G 1 with a short, straight terminal segment and narrow, proximal dorsal flap. Laevimon, however, can be immediately distinguished from Hainanpotamon by the following characters: i) carapace proportionately more strongly convex and raised laterally (versus carapace relatively less strongly convex); ii) postorbital cristae indistinct (versus postorbital cristae distinct); iii) epibranchial tooth very low, rounded (versus epibranchial tooth relatively more developed, triangular); iv) anterolateral margin entire, very weakly cristate (versus anterolateral margin weakly serrated, relatively more distinctly cristate); v) posterior margin of epistome with the lateral and outer parts forming a continuous sinuous margin, with the convex lateral part confluent with the gently concave outer part (versus posterior margin of the epistome with the lateral parts straight and distinct from gently concave outer parts); vi) suture between thoracic sternites 3 and 4 demarcated by distinct, strong ridge (versus suture between thoracic sternites 3 and 4 not discernible); and vii) G 1 terminal segment subcylindrical, with tip truncate (versus G 1 terminal segment conical, with tip tapered) (Figs. 2–6; Dang 1967: fig. 6, 1980: fig. 242; Dang & Tran 1992: figs. 1, 2; see also Table 1; Dai 1995). Other Indochinese potamiscine genera that have swollen, smooth, eggshaped carapaces similar to Laevimon are Thaipotamon Ng & Naiyanetr, 1993 [Thailand], Thaiphusa Ng & Naiyanetr, 1993 [Thailand], and Pudaengon Ng & Naiyanetr, 1995 [Thailand, Laos]. Laevimon is immediately differentiated from these by its unique suite of characters of the third maxilliped, thoracic sternum and G 1 (see Table 1). Crabs of the genus Tiwaripotamon Bott, 1970 [central Vietnam to southern China] also have a relatively smooth carapace (Bott 1970, Ng & Yeo 2001). However, the genus can immediately be distinguished by their distinctly lower and flatter carapace; slender, elongated legs; and third maxilliped with a squarish ischium having a shallow or no sulcus, and a short exopod with a short flagellum. This contrasts with Laevimon species, all of which have a high, swollen carapace; ambulatory legs that are not unusually elongated; and a third maxilliped with a rectangular ischium possessing a distinct sulcus, and a long exopod with a long flagellum (Figs. 2 A, B, 3 A, 4 A, B; cf. Bott 1970, Dai 1999, Ng & Yeo 2001). Distribution. Hai Phong, Thanh Hoa Province, northern Vietnam; Nghe Tinh Province, central Vietnam (Dang & Tran 1992).

Kottelat et al., 26 Sep. 1998; 3 males (largest 27.6 by 20.9 mm) (ZRC 2004.697), Cat Ba Island, 20 º 4757 ” N 107 º00’05” E, northern Vietnam, coll. T. Whitten, 1998. Description. Carapace (Fig. 2 A, B) distinctly transverse, 1.32–1.35 times broader than long, high; dorsal surface strongly convex longitudinally and transversely, glabrous; regions indistinct; cervical grooves faint; Hshaped groove also indistinct. Epigastric cristae poorly developed, rounded, smooth, very weakly separated by faint groove, slightly anterior to postorbital cristae, confluent with postorbital cristae; postorbital cristae indistinct, straight, rounded, smooth, confluent with epibranchial teeth; regions behind epigastric and postorbital cristae smooth. Frontal margin very gently sinuous, cristate; frontal region strongly deflexed downwards, smooth; antennular fossae slitlike when viewed from front; supraorbital margin very gently sinuous, cristate; infraorbital margin straight, cristate; orbital region relatively narrow; eyes normally developed; subhepatic and subbranchial regions rugose. External orbital angle well developed, acutely triangular, outer margin subequal to inner margin, margins cristate, with shallow, narrow, rounded cleft separating it from epibranchial tooth; epibranchial tooth weak, low, rounded; anterolateral margin strongly convex, indistinctly cristate, almost smooth, entire, not confluent with posterolateral margin, running inwards posteriorly; posterolateral margin strongly converging posteriorly, entire, gently convex; branchial region smooth, inflated; metabranchial region smooth, lacking oblique striae. Epistome with median triangle on anterior margin; median tooth on posterior margin very low, broadly triangular, lateral and outer parts forming continuous sinuous margin, with gently concave outer parts and convex lateral parts; median endostomial ridge hardly visible (Fig. 2 B). Third maxilliped glabrous; ischium broadly rectangular, with distinct longitudinal median sulcus; merus squarish, subequal to half of ischium length, with concave outer surface, with smooth margins; palp threesegmented, with tip exceeding proximal margin of merus, lacking any distinctive feature; exopod long, exceeding distal margin of ischium, straight, distally tapered, inner margin of distal part produced as a tooth, flagellum well developed, longer than or subequal to width of merus (Figs. 2 B, 3 A). Chelipeds unequal, outer surface of merus, carpus and palm weakly rugose; fingers strongly gaping, longer than palm, tips hooked and overlapping, carpus armed with robust, obliquely directed subdistal spine on inner margin; merus without subterminal spine (Fig. 2 A). Chelipeds similar in males and females. Ambulatory legs glabrous, relatively short and stout; dactyli elongated, slender; merus unarmed, with upper margin weakly serrated; dactylus of fourth ambulatory leg about 1.3 times as long as propodus, about 6.2 times longer than proximal width; propodus, carpus and merus rugose (Fig. 2 A). Suture between thoracic sternites 2 and 3 distinct, complete, straight; groove or suture between thoracic sternites 3 and 4 demarcated by distinct, strong, complete ridge, fused with tip of margin of abdominal cavity; thoracic sternites 5 and 6 medially interrupted; thoracic sternite 7 completely separated by longitudinal median line; thoracic sternite 8 completely separated by longitudinal median line, lacking transverse ridge; abdominal cavity reaching imaginary line joining median part of coxae of chelipeds (Figs. 1, 2 C). Male abdomen narrowly triangular; telson narrowly triangular, longer than or subequal to proximal width, slightly longer than sixth segment, lateral margins gently concave, tip rounded, proximal margin almost straight; segment 6 elongate rectangular or trapezoidal, median length about half of proximal width, proximal margin almost straight, lateral margins convex; lateral margins of segments 3 to 5 convex (Fig. 2 C). G 1 gently sinuous, slender; terminal segment clearly separated from subterminal segment, relatively short and stout, about 0.3 times length of subterminal segment, subcylindrical, straight, without longitudinal torsion, without swelling on inner margin, dorsal flap present in proximal part, relatively high, narrow, humplike, tip truncate with inner distal angle produced as sharp, narrow projection; groove for accommodation of G 2 marginal; subterminal segment slender, not distinctly constricted or necklike distally, without shelf on upper part of outer margin (Fig. 3 B–E). G 2 with distal segment distinctly longer than half of basal segment, slender, tapering distally, without distal projection; outer margin of basal segment gently convex (Fig. 3 F). Etymology. The species is named after its collector, Dr. Maurice Kottelat. Remarks. Laevimon kottelati, new species, is very similar to L. tankiense (Dang & Tran, 1992). Laevimon kottelati can, however, still be easily separated from L. tankiense by the differences of the carapace and G 1: i) carapace relatively less broad, 1.32–1.35 times broader than long (versus carapace broader, 1.43–1.52 times broader than long); ii) anterolateral and posterolateral margins relatively less strongly convex and less strongly converging, respectively (versus anterolateral and posterolateral margins relatively more strongly convex and more strongly converging, respectively); iii) cleft separating external orbital angle and epibranchial tooth relatively narrower, less distinct (versus cleft relatively broader, more distinct); iv) epibranchial tooth relatively lower and weaker (versus epibranchial tooth relatively higher and more strongly developed); v) ridge demarcating suture between thoracic sternites 3 and 4 complete, fused with tip of margin of abdominal cavity (versus ridge demarcating suture between thoracic sternites 3 and 4 incomplete, broken medially, not fused with tip of margin of abdominal cavity); vi) male abdominal segment 6 lateral margins distinctly convex (versus male abdominal segment 6 lateral margins very gently convex to almost straight); vii) G 1 terminal segment relatively more slen der, with a relatively higher and narrower dorsal flap (versus G 1 terminal segment relatively stouter, with a relatively lower and broader dorsal flap); and viii) G 1 subterminal segment is relatively more slender (versus subterminal segment relatively broader) (Figs. 2–6). Ecological note. The specimens of Laevimon kottelati were collected from along the stream banks as well as a short distance from the streams (M. Kottelat, pers. comm.). This semiterrestrial habit is unusual for freshwater crabs with such carapace physiognomy (high, swollen carapace), instead normally being associated with more terrestrial forest habitats (e.g., Terrapotamon abbbotti, Thaiphusa sirikit, Thaipotamon chulabhorn, Pudaengon spp.) or poorlyoxygenated aquatic habitats (e.g., Somanniathelphusa spp.) (Naiyanetr 1992, 1993; Ng 1993; Ng & Naiyanetr 1993, 1995, 1998; Ng & Kosuge 1997; pers. observ.). Distribution. Hai Phong, northern Vietnam. Laevimon tankiense (Dang & Tran, 1992) (Figs. 4–6) Orientalia tankiensis Dang & Tran, 1992: 19, Fig. 2; Dang & Ho, 2001: 74, Fig. 9. Hainanpotamon tankiensis.— Yeo & Ng, 1999: 641. Material examined. Holotype: male (40.0 by 26.4 mm) (VNCNST), Tan Ky District, Nghe Tinh Province, northern Vietnam, coll. Jul. 1987. Paratype: 1 female (33.5 by 23.4 mm) (VNCNST), same data as holotype. Diagnosis. Carapace distinctly transverse, 1.43–1.52 times broader than long, high; dorsal surface strongly convex longitudinally and transversely, smooth; epigastric cristae very weak, indistinct; postorbital cristae indistinct, rounded; external orbital angle acutely triangular, separated from epibranchial tooth by distinct, broad rounded cleft; epibranchial tooth low but distinct, rounded; anterolateral and posterolateral margins very strongly convex and strongly converging, respectively. Third maxilliped exopod reaching beyond distal margin of ischium, flagellum well developed, subequal to or exceeding width of merus. Ambulatory dactyli long, slender. Suture between thoracic sternites 3 and 4 demarcated by strong incomplete ridge, not fused with tip of margin of abdominal cavity. Male abdomen narrowly triangular; segment 6 with lateral margins very gently convex. G 1 terminal segment about 0.3 times length of subterminal segment; subcylindrical, straight, tip truncate with inner distal angle produced as sharp, narrow projection, with narrow, humplike, dorsal flap in proximal part; subterminal segment relatively slender. G 2 with distal segment longer than halflength of basal segment. Remarks. Laevimon tankiense (Dang & Tran, 1992) differs from its only congener, L. kottelati, new species, by several characters of the carapace, thoracic sternum and G 1 (see Remarks for Laevimon kottelati). The first author examined the types of this species while visiting the VNCNST but, unfortunately, was unable to illustrate specimens. Dang & Tran’s (1992) figure 2 and Dang & Ho’s (2001) figure 9 are therefore reproduced here in Figs. 5 and 6 for comparison. Although the drawings by Dang & Tran (1992) and Dang & Ho (2001) are rather diagrammatic, they nevertheless agree relatively well with the types reexamined. Dang & Tran’s (1992: fig. 2) drawing of the G 1 was made with the structure tilted on its side and hence their figure may be somewhat misleading. In any case, the G 1 of L. kottelati, when viewed and compared from all possible orientations, neither matches the G 1 of the holotype examined by the first author nor the published illustrations of L. tankiense (Dang & Tran 1992, Dang & Ho 2001). Therefore, we are certain that we are dealing with interspecific differences between L. kottelati and L. tankiense. Ecological note. The species occurs in streams in hilly or mountainous areas (Dang & Ho 2001). Distribution. Thanh Hoa Province, northern Vietnam; Nghe Tinh Province, central Vietnam (Dang & Tran 1992).Published as part of Yeo, Darren C. J. & Ng, Peter K.

No full textEngaging China – Reflections from the EU’s and ASEAN’s Responses. EU Centre Background Brief, 3rd January 2019
No full textChina’s rise as a global economic and trading power has taken on a new significance for the Asia-Pacific region as well as the western world in light of USA’s increasing protectionism under the Trump administration. This brief will explore how regional organizations like the Association for South East Asian Nations (ASEAN) and the European Union (EU) as well as their member states respond to the rise of China and its increasing assertiveness in projecting its power and protecting its interests globally. China’s geographical proximity to South East Asia and the power competition between China and USA are important factors that shape the responses of ASEAN nations. This brief looks at the “hedging” and “bandwagoning” strategy employed by ASEAN member states against China. On the other hand, being a more unified actor than ASEAN and a central pillar for a rule-based multilateral world order, the EU hopes to constructively manage its internal differences while engaging China in its reform process. Upon closer look, the author finds that the EU, like ASEAN, is challenged by an unpredictable and unilateral America First under Trump, and an increasingly assertive China. To manage the rising tensions and uncertainties, both regional organisations need to be more cohesive and united. They should also work more closely together to uphold a rule-based multilateral order
Book review: Varieties of State Regulation: How China Regulates Its Socialist Market Economy. Yeo, Yukyung (2020). Cambridge (MA) and London: Harvard University Press
No full textInternational audienceThe book review based on Varieties of State Regulation: How China Regulates Its Socialist Market Economy resumes the main findings of the book and presents several suggestions. The book by Professor Yukyung Yeo points out the particularity in the regulation practices of China. Navigating between the neoliberal and statist approaches which have been developed in industrialized countries, Yeo advances and tests the market-instutitonal approach which has been proven very robust for making sense of the regulatory practices in contemporary China. However, the sectors that the author has researched into -- automobile and telecommunications -- are examined through an economic lens. The political dimension of the regulation -- which is increasingly important for Chinese leaders -- could have been developed in greater detail

Decoding the Disciplines is being used to increase learning in at least nine countries on four continents, and the model has been enriched, as scholars of teaching and learning have
adapted the paradigm to the needs of their institutions. This session will begin with a very brief introduction to the Decoding model, followed by presentations showing how teams in Canada, South Africa, and Australia are putting Decoding to use on their campuses:
David Pace (Indiana University), co-founder of Decoding, will briefly describe the paradigm and its development.
Dr’s Janice Miller-Young and Michelle Yeo at Mount Royal University will provide examples and evidence of the various ways in which the Decoding framework is being used on their
campus. Since 2013 a faculty learning community at Mount Royal has used Decoding for professional development, curriculum design, and research purposes. They will explore
some of the common themes that have emerged from these projects, connect the learning to practical applications for teachers in higher education, and make recommendations for
further work.
Dr Manie Moolman (Teaching and Learning Director: of the Faculty of Law), Prof. Annette Wilkinson (Professor Researcher, at the Centre for Teaching and Learning), and Dr Deirdre van
Jaarsveldt, Lecturer Researcher, from the University of the Free State, South Africa will describe the Decoding Learning in Law project. This 17-member learning community has focused on a
crucial bottleneck to learning in their discipline — reading case law and applying the law to a set of facts - and has used an ‘adapted’ version of the Decoding model that specifically provides for group participation and interaction within a specific discipline. They will provide evidence and reflect on the implementation and will explain that the Decoding model is not only efficient in solving bottlenecks, but that it can also be used as a means for deep reflection and professional development; curriculum design; and the identification of other bottlenecks that could hinder student learning in the faculty.
Adrian Jones (La Trobe University) and Jennifer Clark (University of New England) will describe how Australian-based scholars have used ‘Decoding’ to kick start cross-university conversations about the curriculum priorities for the first-year of tertiary study in five Humanities and Social Sciences disciplines. Each national Threshold Learning Outcome was addressed, and a good practice guide was drawn up, all focused on the crucial first-year. History is discussed as a case
study.
Participants will discuss how Decoding can be put to use on their campuses.

Integrating new assessment strategies into mathematics classrooms: an exploratory study in Singapore primary and secondary schools
No full textEducational researchers and practitioners have in recent years paid mounting attention to the importance of new assessment (or the so-called alternative assessment) strategies in Mathematics instruction to better reflect the new desired educational goals and shifted values in education. However, research is wanting in this area, particularly in Singapore's educational setting. This project seeks to investigate the influence of using new assessment strategies in Mathematics teaching and learning on students' achievements, in both the cognitive and affective domains, in our local school settings. A quasi-experimental study with about 15-20 teachers at primary and lower secondary levels will be carried out to assess the impact of using a variety of strategies (e.g., projects, journal writing, oral presentation, performance tasks, student self-assessment, classroom observation and interview, etc.) for three school semesters on students' learning. The project will also look into issues concerning how to use new assessment strategies effectively in classrooms in local schools. For this purpose, data will be collected from classroom observation, interviews with teachers and students, and questionnaire surveys. It is hoped that the project will provide research-based evidence and practical suggestions for promoting the effective use of alternative assessment in Singapore Mathematics classrooms. <br/
Conserved metabolite regulation of stress granule assembly via AdoMet

Q., Yeo, G., & Wilhelm, J. E. Conserved metabolite regulation of stress granule assembly via AdoMet. Journal of Cell Biology, 219(8), (2020): e201904141, doi:10.1083/jcb.201904141.Stress granules (SGs) are evolutionarily conserved condensates of ribonucleoproteins that assemble in response to metabolic stresses. Because aberrant SG formation is associated with amyotrophic lateral sclerosis (ALS), understanding the connection between metabolic activity and SG composition can provide therapeutic insights into neurodegeneration. Here, we identify 17 metabolic enzymes recruited to yeast SGs in response to physiological growth stress. Furthermore, the product of one of these enzymes, AdoMet, is a regulator of SG assembly and composition. Decreases in AdoMet levels increase SG formation, while chronic elevation of AdoMet produces SG remnants lacking proteins associated with the 5′ end of transcripts. Interestingly, acute elevation of AdoMet blocks SG formation in yeast and motor neurons. Treatment of ALS-derived motor neurons with AdoMet also suppresses the formation of TDP-43–positive SGs, a hallmark of ALS. Together, these results argue that AdoMet is an evolutionarily conserved regulator of SG composition and assembly with therapeutic potential in neurodegeneration.Work from the Wilhelm laboratory was supported by a grant to J.E.
