The effect of demographic changes on saving for life cycle motives in developing countries
No full textIf developing countries follow the same paths that industrialized countries have followed, saving for retirement will initially become more important as the population growth rate declines. To calculate the potential importance of life-cycle savings (saving for retirement), the paper presents a simulation model that translates demographic projections into savings-rate projections. It simulated aggregate rates for life-cycle savings for Brazil, China, Korea, Mexico, Nigeria, Pakistan and Turkey. The savings rates increase 5 or 6 percentage points when the last baby boomers enter the work force and begin to save after their children leave home. The effect on life-cycle savings is dramatic; the effect on total savings rates which are often three or four times as high, is not. Simulated life-cycle savings rates peak at an absolute 10 percent or less in all cases. The patterns of these projections seem robust with regard to assumptions about productivity growth, interest rates, and age-specific participation in the labor force.Banks&Banking Reform,Environmental Economics&Policies,Economic Theory&Research,Health Monitoring&Evaluation,Inequality
Rhotana biermani Zelazny & Webb 2011, new combination
No full textRhotana biermani (Schmidt, 1926), new combination Decora biermani Schmidt, 1926: 240 Redescription. Forewings and abdomen missing in only specimen available. Colour stramineous, facial carinae in front of eyes, mesonotum and fore tibiae light brown. Hindwings colourless. Facial carinae contiguous at their bases; subantennal processes well -, lateral carinae of pronotum little developed. Schmidt provides the following description of the forewing (translated from German): "Forewings glassy with a smoky-grey band crossing the wing at the end of its basal third. Forewing marks in number and position like in Decora pavo Bierman. Apical margin and veins between the marks red. Anterior apical crossveins and band before the anterior apical margin smoky-grey." Etymology. The species is named for C.J.H. Bierman, the author of the genus Decora, and ' biermani ' is a latinized noun used in the genitive case. Type material. Holotype (sex unknown, abdomen missing), INDONESIA: Buru Island; labels: 1) Buru 1921/ Station 17/ leg. L.J. Toxopeus/ 1300 M 2) Typus 3) Decora / Biermani Schmidt / Edm. Schmidt / determ. 1926 (MZWP). Distribution. Buru Island (Maluku, Indonesia). Diagnosis. Schmidt has stressed the similarity to Rhotana pavo (Bierman), found in Sumatra and Borneo. It is not possible to provide an adequate characterisation of this species since the holotype has missing forewings and no abdomen. It seems to differ from Rhotana pavo (Bierman) by its lighter colour (e.g. foretibiae and labium), by the facial carinae being contiguous at their bases, and by the poorly developed lateral carinae of the pronotum.Published as part of Zelazny, B. & Webb, M.

Rhotanella sophiae Zelazny & Webb 2011, sp. nov.
No full textRhotanella sophiae Zelazny, sp. nov. (Fig. 257) Description. Forewings length in male about 4.0 mm. Forewings with a large red area along base of costa, covering nearly half of first costal cell; third and fourth subcostal sectors covered by a red U-shaped mark; Sc+R, first, third and fourth subcostal sectors and veins in apical half of wing red; remaining veins light brown, interrupted by numerous light dots. Hindwings colourless; in apical third slightly infuscated with red veins. Male genital styles widening towards end which is truncated, its apical margin bent inwards; both dorsal processes short and thick, contiguous. Aedeagus ending in two long and pointed processes which are straight and contiguous. Etymology. The species is named for Sophia Zelazny, the daughter of the senior author, and ' sophiae ' is a latinized noun used in the genitive case. Type material. Holotype ♂ (forewing 4.0 mm), PAPUA NEW GUINEA; labels: 1) NEW GUINEA (NW)/ River Tor (mouth)/ 4 km E of Hol / Maffen, 19. VII '59 2) T. C. Maa / Collector (BPBM). Distribution. New Guinea. Diagnosis. Rhotanella sophiae is similar to R. cyclops sp. nov. and to R. thyrsis Fennah, both also from New Guinea. It can be separated from R. cyclops sp. nov. by the large red area in the basal costal cell. It can be distinguished from R. thyrsis by the forewings having the first subcostal sector red and light dots along the basal forewing veins, by the contiguous dorsal processes on the male genital styles and by the long and slender terminal processes of the male aedeagus.Published as part of Zelazny, B. & Webb, M.

Lectures focusing on the theme of Sport History and Sport Mythology were presented by Allen Guttmann, Richard D. Mandell, Stephen Hardy, and Donald G. Kyle. An additional paper by Steven A. Riess was the winning entry in the 1989 Webb-Smith Essay Competition. Revised and edited to varying degrees by the authors and co-editors, the five papers are collected in this volume, with an introduction by Jack W. Berryman. The co-editors wish to thank all the authors for their contributions and their cooperation
Asylum and Complexity : The Vulnerable Identity of Law as a Complex System
No full textThe present chapter uses complexity theory to argue that the so-called ‘consensus approach’ of the European Court of Human Rights (henceforth ‘the Court’ or ‘ECtHR’) can be a rational response to the cognitively demanding task of interpreting and applying the European Convention of Human Rights (henceforth ‘the Convention’ or ‘ECHR’) to member states of the Council of Europe. The chapter begins by setting the stage in two ways. First, drawing on recent literature on the subject, I provide a succinct sketch of a number of complexity theory concepts and argue that they can be relevant to the study of the ECHR. Second, I briefly present the consensus approach and some of the criticisms that have been addressed against it, with specific reference to the moral reading of the Convention. The moral reading of the ECHR, associated with Ronald Dworkin’s legal
interpretivism and defended by leading commentators such as George Letsas (Letsas 2007), is one of the most forceful sources of criticism of the consensus approach. It is also an independently plausible and sophisticated theory of interpretation of the ECHR. Thus, using complexity theory to show that, despite initial appearances, the moral reading
of the Convention could be compatible with the consensus approach is an interesting result in itself
Monobazus Distant
No full textMonobazus Distant Remarks. A review of this genus is in preparation by the second author and C.A. Viraktamath. Monobazus dissimilis (Distant), comb. nov. (Plate 1, d; Fig. 4). Deltocephalus fuscovarius Distant. Syn. nov. Material examined. Pakistan: 213, 4 Ƥ, Sindh Prov., Tando Jam, 7.xi.07. India: several specimens from throughout India and Sri Lanka, including the syntypeƤ of Xestocephalus dissimilis and 2 Ƥ syntypes of Deltocephalus fuscovarius (BMNH). Remarks. This species is similar to Osbornellus (Mavromoustaca) macchiae (see below) in having a pair of long basal paraphyses of the aedeagus (Figs 4 k-m) but these are dorsal rather than ventral and its subgenital plate is distinctive in being very long with its apical part digitate and lightly sclerotised, macrosetae relatively slender, and with both marginal and dorsal long fine setae.Published as part of Khatri, Imran & Webb, Michael D., 2010, The Deltocephalinae leafhoppers of Pakistan (Hemiptera, Cicadellidae), pp. 1-47 in Zootaxa 2365 on page 7, DOI: 10.5281/zenodo.19365
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
