 Paul Allatson PORTAL : Journal of Multidisciplinary International Studies , 2010, Abstract: This issue of PORTAL Journal of Multidisciplinary International Studies comprises five articles in its general essays section, and two works in its creative works section. We are delighted with the inclusion of the first three essays: “‘A Bit of a Grope’: Gender, Sex and Racial Boundaries in Transitional East Timor,” by Roslyn Appleby; “Undermining the Occupation: Women Coalminers in 1940s Japan,” by Matthew Allen; and “Pan-pan Girls: Humiliating Liberation in Postwar Japanese Literature,” by Rumi Sakamoto. These essays were presented in earlier formats at the two-day workshop, “Gender and occupations and interventions in the Asia Pacific, 1945-2009,” held in December 2009 at the Centre for Asia Pacific Social Transformation Studies (CAPSTRANS), University of Wollongong. The workshop was convened by Christine de Matos, a research fellow at CAPSTRANS, and Rowena Ward, a Lecturer in Japanese at the Language Centre, in the Faculty of Arts, University of Wollongong. The editorial committee at Portal is particularly grateful to Christine and Rowena for facilitating the inclusion of these essays in this issue of the journal. Augmenting those studies is “Outcaste by Choice: Re-Genderings in a Short Story by Oka Rusmini,” an essay by Harry Aveling, the renowned Australian translator and scholar of Indonesian literature, which provides fascinating insights into the intertextual references, historical contexts and caste-conflicts explored by one of Indonesia’s most important Balinese authors. Liliana Edith Correa’s “El lugar de la memoria: Where Memory Lies,” is an evocative exploration of the newly emergent Latin(o) American identifications in Australia as constructed through self-conscious memory work among, and by, a range of Latin American immigrant artists and writers. We are equally pleased to conclude the issue with two text/image works by the Vancouver-based Canadian poet Derek Symons.

 Mathematics , 2006, Abstract: We give a systematic definition of the fundamental groups of gropes, which we call grope groups. We show that there exists a nontrivial homomorphism from the minimal grope group M to another grope group G only if G is the free product of M with another grope group.
 Mathematics , 2002, Abstract: We explain how the usual algebras of Feynman diagrams behave under the grope degree introduced in "Grope cobordism of classical knots." We show that the Kontsevich integral rationally classifies grope cobordisms of knots in 3-space when the class'' is used to organize gropes. This implies that the grope cobordism equivalence relations are highly nontrivial in dimension three. We also show that the class is not a useful organizing complexity in four dimensions since only the Arf invariant survives. In contrast, measuring gropes according to height'' does lead to very interesting four-dimensional information (Cochran-Orr-Teichner). Finally, several low degree calculations are explained, in particular we show that S-equivalence is the same relation as grope cobordism based on the smallest tree with an internal vertex.
 Mathematics , 2000, Abstract: We explain the notion of a grope cobordism between two knots in a 3-manifold. Each grope cobordism has a type that can be described by a rooted unitrivalent tree. By filtering these trees in different ways, we show how the Goussarov-Habiro approach to finite type invariants of knots is closely related to our notion of grope cobordism. Thus our results can be viewed as a geometric interpretation of finite type invariants. An interesting refinement we study are knots modulo symmetric grope cobordism in 3-space. On one hand this theory maps onto the usual Vassiliev theory and on the other hand it maps onto the Cochran-Orr-Teichner filtration of the knot concordance group, via symmetric grope cobordism in 4-space. In particular, the graded theory contains information on finite type invariants (with degree h terms mapping to Vassiliev degree 2^h), Blanchfield forms or S-equivalence at h=2, Casson-Gordon invariants at h=3, and for h=4 one has the new von Neumann signatures of a knot.
 Mathematics , 2015, Abstract: To a special type of grope embedded in 4-space, that we call an admissible grope, we associate a length function for each real number q at least 1. This gives rise to a family of pseudo-metrics d^q, refining the slice genus metric, on the set of concordance classes of knots, as the infimum of the length function taken over all possible grope concordances between two knots. We investigate the properties of these metrics. The main theorem is that the topology induced by this metric on the knot concordance set is not discrete for all q>1. The analogous statement for links also holds for q=1. In addition we translate much previous work on knot concordance into distance statements. In particular, we show that winding number zero satellite operators are contractions in many cases, and we give lower bounds on our metrics arising from knot signatures and higher order order signatures.
 Rolando B. Modina Kasarinlan : Philippine Journal of Third World Studies , 1986, Abstract: East Timor is a tragedy. It is a small country with no strategic military value. In the eyes of the world’s power brokers, East Timor is nothing. More importantly, it is a tragedy because what Indonesia did and is still doing in East Timor is a gross violation of basic human rights—the basic right of a people to live in peace and self-determination. This paper examines the many difficulties East Timor is facing amidst the presence of key actors such as the UN, ASEAN and the European Economic Community. It argues that for the East Timor case, only a political solution, and not a military one, is viable. The international support for Indonesia by governments motivated by economic and practical considerations is detrimental to the cause of the East Timorese people. As the paper concludes, East Timor is a case where people matter the least.
 Peter Teichner Mathematics , 2003, Abstract: We explain new developments in classical knot theory in 3 and 4~dimensions, i.e. we study knots in 3-space, up to isotopy as well as up to concordance. In dimension~3 we give a geometric interpretation of the Kontsevich integral (joint with Jim Conant), and in dimension 4 we introduce new concordance invariants using von Neumann signatures (joint with Tim Cochran and Kent Orr). The common geometric feature of our results is the notion of a grope cobordism.
 Peter D. Horn Mathematics , 2008, Abstract: We consider the Grope filtration of the classical knot concordance group that was introduced in a paper of Cochran, Orr and Teichner. Our main result is that successive quotients at each stage in this filtration have infinite rank. We also establish the analogous result for the Grope filtration of the concordance group of string links consisting of more than one component.
 Hye Jin Jang Mathematics , 2015, Abstract: We study knots of order 2 in the grope filtration $\{\G_h\}$ and the solvable filtration $\{\F_h\}$ of the knot concordance group. We show that, for any integer $n\ge4$, there are knots generating a $\Z_2^\infty$ subgroup of $\G_n/\G_{n.5}$. Considering the solvable filtration, our knots generate a $\Z_2^\infty$ subgroup of $\F_n/\F_{n.5}$ $(n\ge2)$ distinct from the subgroup generated by the previously known 2-torsion knots of Cochran, Harvey, and Leidy. We also present a result on the 2-torsion part in the Cochran, Harvey, and Leidy's primary decomposition of the solvable filtration.
 Diversity , 2013, DOI: 10.3390/d5010139 Abstract: The Wallacean island of Timor is of particular biological interest due to its relatively large size and transitional location between the Indo-Malayan and Australasian biogeographic realms. However, the origins and levels of endemism of its invertebrate fauna are poorly known. A recent study of Timorese ants revealed a diverse fauna with predominantly Indo-Malayan affinities, but species-level taxonomy was considered to be too poorly understood for an analysis of levels of endemism. The highly diverse Old World tropical genus Polyrhachis represents a notable exception, and here we analyse levels of endemism in the Polyrhachis fauna of Timor and surrounding islands. We supplement the species listed in the previous study with additional collections to record a total of 35 species of Polyrhachis from Timor and surrounding islands. Only 14 (40%) of the 35 species could be named ( P. constricta, P. costulata, P. gab, P. sokolova, P. hera, P. illaudata, P. rixosa, P. acantha chrysophanes, P. saevissima, P. bicolor, P. cryptoceroides, P. dives, P. longipes and P. olybria), and the large majority of the remaining species have not previously been collected. These are very likely to be endemic to Timor and surrounding islands, and point to remarkably high levels (>50%) of endemism in the regional ant fauna.
