No full textPheidole chloe Forel, new status Pheidole goeldii subsp. chloe Forel 1908c: 56. Types Mus. Hist. Nat. Geneve; Mus. Comp. Zool. Harvard. Etymology Gr chloe, first green shoots of plants in spring, allusion unknown. diagnosis A member of the flavens group close to striaticeps of Mexico and Central America (and a possible synonym of it), much less so to the other species listed in the heading, and distinguished as follows. Major: antennal scrobes present; entire dorsal surface of head, except for frontal triangle, covered by longitudinal carinulae, which do not curve inwardly toward midline at occiput; humerus subangulate in dorsal-oblique view; mesonotal convexity absent in both side and dorsal-oblique views; head wider than long (HW/HL 1.04); pronotum lacks transverse carinulae. Minor: longitudinal carinulae stretch from mesopleuron to sides of propodeum. Measurements (mm) Syntype major: HW 1.00, HL 0.96, SL 0.56, EL 0.14, PW 0.50. Syntype minor: PW 0.36 (head missing in syntype available). Color Major: concolorous light reddish brown. Minor: body brownish yellow (color of head unknown). Range Costa Rica and Mexico. Longino (1997) does not distinguish this species from striaticeps, although the two appear to be different. He reports " striaticeps, " which may include both species, from the Atlantic slope to 500 m and Pacific lowlands of Costa Rica. Biology Longino (1997) reports " striaticeps," which as noted, may include both true striaticeps and chloe, from mature rainforest, nesting beneath the bark of rotten stumps and logs.

Out With the Old and In With the New: Something Museums Always Do
No full textChloe White describes the evolution of museums from private collections of curiosities to publicly funded institutions serving the purposes of education, entertainment, and historical preservation. Recounting ways in which museums have adopted technological advances (gramophones, dramagraphs, films, audio guides), White urges museums to employ virtual and augmented reality technologies to revive interest in museums (at a time when people have endless entertainment options available) and to make museums appealing to a wider audience
Powering Afghanistan: ethnic rivalries over the TUTAP power line
No full textFollowing protests and violence in Afghanistan, Rabia Nasimi and Chloe Blades discuss the proposed TUTAP project, which promises to double electricity coverage. They consider why the Hazara minority in particular feel like they are being excluded from the benefits that the power line will bring, and why this is seen as part of a wider trend of neglect by the incumbent National Unity Government
Environmental and wider economic implications of modifications to environmental tax reform
No full textThe most common definition of Environmental Tax Reform (ETR) is the use of the revenue from environmental taxes to reduce distortionary labour taxes. However, the PETRAS project has shown that there are a number of social and political impediments to implementing such reform. This paper
firstly outlines some of the environmental and economic implications of environmental taxes generally. It goes on to explore three broad approaches to ETR, based on the allocation of the tax revenues, and explores the environmental and economic implications of each approach and the likelihood of political and social acceptance. Particular attention is paid to ameliorating regressive impacts and impacts on competitiveness. It is concluded that some combination of hypothecating a proportion ofrevenues to environmental projects and diverting rest to reduce labour taxes is probably the best approach in light of the results of the project. The balance should depend upon local labour market and macroeconomic conditions, the extent to which environmental projects are already funded and the extent of government failure. Funding should only provided to environmental projects if it can be shown that, in themselves, they are economically efficient. In addition, it is most important that a proportion of the funds be used to ameliorate any regressive impacts. It is also important to bear in mind that hypothecation or recycling of revenue is not the same as a tax shift, which is a reform of the entire system, so some of these approaches may take away from the integrity of ETR. The paper concludes with some of the initiatives that are likely to be necessary to facilitate social and political acceptance of this approach to ETR

It serves as a platform for STH students to share their academic work, theological reflections, and life experiences with one another and the wider community.A series of reflections on Sabbath by Chloe McElyea
Author-Illustrator
No full textThis essay investigates the concept author-illustrator by drawing on two influential essays – ‘Death of the Author’ by Roland Barthes and ‘What is an Author?’ by Michel Foucault. By engaging with the key points of debate that emerge from these positions, this essay argues that the notion of author-illustrator is part of a wider discursive field that is embedded in a complex, commodified, multimedia public sphere where the author is paradoxically reinscribed and erased. This environment is changing the nature of the text, authorship, and reader-text interaction, but until now the concept author-illustrator has been largely absent from these discussions

Similar to male (Fig. 1A), length 1.9–2.1 mm, metaventrite and first abdominal ventrite unmodified; last abdominal tergite bearing a long and stout median spine prolonged backwards (Figs 1A and 2D).</p> <p> <b>Distribution</b>. The new species is endemic from Marchesato (Calabria, Kroton province).</p> <p> <b>Etymology</b>. The new species is named in honor of the environmental association Chloe of Strongoli (KR), who has contributed so much to the field research, and to whom we wish success.</p> <p> <b>Ecological notes</b>. All specimens were collected by sifting litter in oak (<i>Quercus</i>) forests.</p> <p> <b>Comparative notes</b>. The species of <i>Pselaphogenius</i> of the <i>fiorii</i> group have symmetric aedeagi (except <i>P. lucanicus</i> Besuchet, 1964 which shows an aedeagus partially asymmetric with the presence of a ventral lamina), characterized by two evident lateral apophyses of the basal capsule, two well developed and sinuated parameres, one median apical lamina and the armature of internal sac simple consisting of a single piece. Although some of these portions are sometimes recognizable, despite being more or less modified, in the structure of the aedeagus of the other species of the genus <i>Pselaphogenius</i>, they never show the symmetry that characterizes the aedeagi of the species of the <i>Pselaphogenius</i> of <i>fiorii</i> species group.</p> <p> <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> by the aedeagal and exoskeleton features clearly belongs to the <i>Pselaphogenius fiorii</i> species group, but it is easily distinguished from all the species of this group by some characters of the male and the female. For the head clearly punctate, the reticulated dorsal region of the pronotum, and the elytral lateral fovea slightly larger than medial one, <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> shows the greatest similarities to <i>P. aspromontanus</i> (Reitter 1910), <i>P. lucanicus</i> Besuchet, 1964 and <i>P. neapolitanus</i> Besuchet, 1964. <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> is distinguished from the males of these three species by the characters of the aedeagus (cfr. Fig. 1B and Figs 28–33 in Besuchet, 1964), as well as by the secondary sexual characters. The male of <i>P. chloe</i> <b>sp. n.</b> has the metaventrite raised in the middle in a conical process rounded at the apex (this conical process is pointed in the males of the other three species) and, especially, the dorsal surface of first ventrite of <i>P. chloe</i> <b>sp. n.</b> is raised in the middle from the base up to about 2/3 of its length, while it is occupied almost for the entire length of the ventrite by a median longitudinal oval-shaped depression in the males of the other three species. The female <i>P. chloe</i> <b>sp. n.</b> is easily distinguished because its last abdominal tergite bears a long and stout median spine prolonged backwards (Figs 1A, 2D), while in the <i>P. aspromontanus</i> female the last abdominal tergite ends in a pointed tip (Fig. 2C) and the posterior margin of the last abdominal tergite of <i>P. neapolitanus</i> is rounded (Fig. 2A). The female of <i>P. lucanicus</i> is still unknown.</p> <p> <i>P. calabrus</i> (Reitter, 1910) is also present in Calabria, this species is easily distinguished from <i>P. chloe</i> <b>sp. n.</b> by the tegument of the head and the pronotum smooth and shiny, the features of the aedeagus (cfr. Fig. 1B and Figs 10-11 in Sabella 1992), the metaventrite of the male that is raised in the middle in a pointed conical process (rounded at the apex in <i>P. chloe</i> <b>sp. n.</b>), the dorsal surface of the first ventrite of male that is traversed almost for its entire length by a median longitudinal oval-shaped depression (raised in the middle from the base up to about 2/3 of the ventrite length in <i>P. chloe</i> <b>sp. n.</b>). The last tergite of the female of <i>P. calabrus</i> is triangular (bearing a long and stout median spine in <i>P. chloe</i> <b>sp. n.</b>) (cfr. Figs 2B and 2D).</p>Published as part of <i>Sabella, Giorgio, Viglianisi, Fabio Massimo & Bekchiev, Rostislav, 2019, A new species of Pselaphogenius Reitter, 1910 of the fiorii species group from southern Italy (Coleoptera, Staphylinidae, Pselaphinae), pp. 387-394 in Zootaxa 4585 (2)</i> on pages 388-392, DOI: 10.11646/zootaxa.4585.2.12, <a href="http://zenodo.org/record/2637282">http://zenodo.org/record/2637282</a>
Muslim supplementary classes and their place within the wider learning community : a Redbridge-based study
No full textUsing his own professional experiences and fieldwork in the north-east of London as a
starting point, the author suggests that the time is now right to consider the place of Muslim
supplementary education in a wider social and educational setting. He suggests that four
factors support this: the growing public interest in the emergence of British Islam; the
continuing debate about the efficacy of traditional forms of Islamic education; the increasing
use of networking within the educational community; and the growing official recognition of
the contribution made by supplementary schooling.
Following a review of a wide range of relevant literary material, the author draws on a
number of life-story interviews in order to portray the reality and variety of British Muslims'
experience of Islamic education. The outcomes of ethnographic fieldwork are then used to
describe and analyse what takes place in a British maktab (elementary mosque school). This
includes a detailed explanation of how and why the Qur'an is learned, particularly by those
individuals who are training to become huffaz (those who have committed the whole Qur'an
to memory).
The ways in which Muslim supplementary schools might form part of the wider social and
educational community are then explored together with factors that might block or encourage
the creation of such an ideal. Analysis includes a review of existing organisational attempts
to promote the work of supplementary schooling. A case is also presented for the reappraisal
of the role of memorisation as a distinct form of learning.
The thesis ends with a concluding statement, focusing on the ideal of maktabs and
mainstream LEA schools working together to mutual benefit, and a number of
recommendations aimed at researchers and those involved in both Muslim and wider
community schooling
Lagrangian analysis of turbulent rotating convection
No full textThis study aims to explore how the flow transition from one state to the other in rotating convection will affect the Lagrangian statistics of (fluid) particles. 3D Particle Tracking Velocimetry (3D-PTV) is employed in a water-filled cylindrical tank of equal height and diameter 200 mm. The measurements are performed in the central volume of 50 × 50 × 50 mm3 at a Rayleigh number Ra = 1.28 × 109 and Prandtl number Pr = 6.7. We are reporting the velocity and acceleration pdfs for different Rossby numbers. For different rotation rates, the transverse velocity pdfs show a Gaussian distribution. The vertical velocity pdf has slightly wider tails for stationary and high rotation rate cases, while it approaches the Gaussian distribution for intermediate rotation rates. The acceleration pdfs have significantly wider tails in comparison to those of a Gaussian distribution which is similar to the other turbulent flows. Increasing rotation results in less intermittency in vertical acceleration in the center of RB
Rethinking Asian Drama
No full textGunnar Myrdal published Asian Drama in 1968, a work which made important analytical contributions to our understanding of development but was deeply pessimistic about Asia's future prospects. Since then, contrary to Myrdal's expectations, Asia's development has been remarkable, although transformations have been uneven across countries and unequal between people. This paper explains the conception and design of the UNU-WIDER study on Asian Transformations, which seeks to analyse the amazing story of economic development in Asia over the past 50 years. It begins with reflections on Gunnar Myrdal, the author, and rethinking Asian Drama, the book, in retrospect 50 years later. It goes on to outline the rationale and objective of the study. It then discusses some critical issues and lessons that emerge - diversity in development, history and context, economic growth and structural change, wellbeing of people, markets and governments, economic openness, and institutions and policies - to serve as a teaser. It concludes with some brief reflections on Asia's future prospects over the next 25 years
