No full textJohn H. Wheeler [b. 1908, d.1978] began his academic career at Morehouse College in 1925. He graduated summa cum laude with a Bachelor of Arts degree in 1929. In 1947, Wheeler graduated from the law school at the North Carolina College at Durham (now North Carolina Central University). Beginning as a teller at the Mechanics and Farmers Bank in 1929, he rose to become president of the bank in 1952. Mechanics and Farmers Bank was a black-owned financial institution in a city that boasted several thriving black enterprises, including the North Carolina Mutual Life Insurance Company (N.C. Mutual). Wheeler was heavily involved in politics and education through various positions within the federal government and on various boards of trustees for institutions like Morehouse College, Atlanta University, Lincoln Hospital, and the National Scholarship Service for Negro Students. While serving two presidents, Wheeler devoted his time to the development of low-income housing, focused on race relations, and the elimination of poverty.

Understanding risky driving among motorized two-wheeler drivers: The role of time-related anxiety and impunctuality
No full textMotorized Two-Wheeler (MTW) drivers significantly contribute to road fatalities due to their vulnerability and the higher severity of crashes. Risky driving behavior, such as violations and errors, is a key precursor to road crashes. Understanding the factors that influence such risky behavior can shed light on opportunities for risk management. In this investigation, data from 460 motorized two-wheeler drivers were collected through an online questionnaire, exploring Red Light Running (RLR), lane sharing, and turning without indicating driving tendencies, latent psychological factors, and demographic attributes of the participants. The analysis was conducted in two steps: (a) decision trees were developed to classify risky driving behavior, and (b) binary logistic regression models were developed to quantify risky driving choices based on demographic and latent psychological variables, as well as interaction variables. The results showed that as driver anxiety increased, the probability of lane sharing rose from 76.3% to 87.9% in normal driving situations and from 80.3% to 96.6% in time-pressure driving situations, respectively. Furthermore, the results revealed that the odds of running red lights and lane sharing decreased to 0.57 and 0.68, respectively, for older drivers compared to young drivers. Overall, this study quantified the impact of underlying psychological factors and demographic parameters, as well as their combined effects, on assessing traffic violations, traffic errors, and non-illegal dangerous driving behaviors among motorized two-wheeler drivers. Additionally, the study discusses the implications and policy interventions related to the legalization of lane sharing and the risks associated with time-pressure driving in online food delivery systems. These findings can inform evidence-based policymaking to achieve road safety goals.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Safety and Security Scienc
Agaporomorphus colberti Miller & Wheeler 2008, sp. n.
No full textAgaporomorphus colberti sp. n. (Figs 1, 6, 7–9, 21) Type locality. Venezuela, Departamento Amazonas, Rio Negro, Rio Baria, Dpt Rio Negro, 00°55'N 066°10'W. Diagnosis. Agaporomorphus species are extremely similar in characters such as size, general shape and coloration (Fig. 1). This species can be distinguished from all other known Agaporomorphus except A. knischi by the following character combination in males: 1) antennomeres V and VI broadly expanded with VI more expanded than V and with a distinct emargination on the posteroventral surface (Fig. 4), 2) abdominal sternite V with an apicomedial triangular process (Figs 5, 6), and 3) abdominal sternite VI with a broad medial fovea (Figs 5, 6). This new species can be clearly placed within a group of species (the A. knischi species group) characterized by distinctly modified male genitalia with a short series of fine setae on each side of the ventral surface (Figs 7, 10, 13, 17). Within this group, A. colberti sp. n. is most similar to A. knischi in having the character combination indicated above, but differs from that species in the shape of the male median lobe of the aedeagus (Figs 7, 8) which is broader in ventral and lateral aspects and has a prominently broad and dorsally angulate ventral region near the base that is narrower in A. knischi (Figs 17, 18), among numerous other shape features. Also, the posteromedial spine on abdominal sternite V is smaller in A. colberti sp. n. (Fig. 5) than in A. knischi (Fig. 6). Description. Measurements. TL = 2.93–3.18mm, GW = 1.39–1.57mm, PW = 1.24–1.38mm, HW = 0.78– 0.87mm, EW = 0.49–0.58mm, TL/GW = 1.97–2.18, HW/EW = 1.50–1.64, FW/FL = 2.59–3.22. Coloration (Fig. 1). Red-brown on all dorsal surfaces, broadly light yellow along anterior margin of elytron and lateral margins of pronotum. All ventral surfaces and appendages yellow-brown except abdominal sternites red-yellow. Sculpture and structure. Pronotum with microsculpture consisting of fine cells, with few very fine punctures interspersed; lateral pronotal bead fine, absent in anterior one-fifth. Prosternum medially strongly carinate, carina extending onto prosternal process; prosternal process medially with a distinct, sharp longitudinal carina extending to apex, laterally with strongly beaded margins, apex pointed. Elytron covered with extremely fine, evenly spaced, short striae, striae more punctiform laterally and apically. Metafemur moderately broad, length about 3 × greatest width. Male genitalia; Median lobe in lateral aspect robust, with broad expansion dorsad, apex elongate, sublinear, with distinct dorsally-directed lobe on right side medially and very broad, angular region subbasally, with linear series of fine setae on each side of dorsal midline (Fig. 7); in ventral aspect very robust, broad, with complicated folding and structures (Fig. 8). Lateral lobe broad basally, strongly narrowed medially, apical half very slender, apicomedially with large membranous lobes bearing extensive series of long setae (Figs 9). Female genitalia; Spermatheca long, loosely coiled, slender, tapered to spermathecal duct; spermathecal duct relatively short; fertilization duct long, coiled; gonocoxa slender, lateral margin broadly convex, apex expanded; laterotergite very slender, elongate. Sexual dimorphism. Male protarsal claws unmodified; male pro- and mesotarsal claws about half length of mesotarsomere V; male without apical lobe on mesotarsomere V; male protarsomeres I and II broadened, protarsomere I with two large adhesive setae, protarsomere II without adhesive setae; male mesotarsomeres I and II slightly broadened, mesotarsomere I with one large, medial adhesive seta and two large, apical adhesive setae, mesotarsomere II with two smaller, apical adhesive setae; female pro- and mesotarsomeres unmodified. Male with fine but distinct triangular, posteriorly-directed prominence medially along posterior margin of visible abdominal sternite V (Fig. 5); female without prominence. Male with broad, elongate depression medially on abdominal sternite VI (Fig. 5); female without depression. Male with distinct parallel series of rugulosities on each side of midline on abdominal sternite III (Fig. 5); female without rugulosities. Male antennomeres V and VI modified, V broadly triangular, VI broad with large posterior emargination (as in Fig. 4); female antennomeres unmodified. Male metafemur unmodified. FIGURES 7–20.

Etymology. This species is named to honor comedian and author, Stephen T. Colbert. Phylogenetic relationships. The phylogenetic analysis resulted in a single parsimony tree (Fig. 21, length=13, CI=92, RI=94). This topology is identical to the one found by Miller (2005) with the addition of A. colberti sp. n. as the unambiguous sister to A. knischi (Fig. 21) based on the synapomorphy of modified antennomere V in addition to VI (e.g. Fig. 4, A. tambopatensis also has antennomere VI modified, though to a lesser extent, Fig. 3). Although not otherwise coded in this analysis because of challenges in homologizing complex shape features, A. colberti sp. n. and A. knischi exhibit considerable general similarity in the shape of the male median lobes (Figs 7, 8, 15, 18). Distribution. Agaporomorphus colberti sp. n. is currently known only from the type locality in extreme southern Venezuela near the border with Brazil. This is the only Agaporomorphus known from Venezuela. Material examined.

Informal regulation of industrial pollution in developing countries : evidence from Indonesia
No full textThe authors test a model of supply-demand relations in an implicit market for environmental services when formal regulation is absent. They use plant-level data from Indonesia for 1989-90, before the advent of nationwide environmental regulation. Treating pollution as a derived demand for environmental services, their model relates emissions of biological oxygen demand to the price (expected cost) of pollution; to prices of other inputs (labor,energy, materials); and to enterprise characteristics that may affect pollution demand, including scale, vintage ownership, and efficiency. The price of pollution is determined by the intersection of plant-level demand and a local environmental supply function, enforced by community pressure or informal regulation. Environmental supply is affected by community income, education, the size of the exposed population, the local economic importance of the plant, and its visibility as a polluter. Their results are strongly consistent with the existence of an informal"pollution equilibrium."Pollution intensity declines with increase in plant size, efficiency, and local materials prices. Older plants and publicly owned facilities are more pollution intensive; multinational ownership has no independent effect. The results also suggest that the price of pollution is higher when plants are particularly visible and is far lower in poorer, less-educated communities. Thus the intensity of pollution is far higher in such communities. While it would be premature to generalize from these results, they suggest that the model of optimal pollution control in environmental economics is more relevant for developing countries than many have believed. Community-factory interactions seem to reflect environmental supply-demand considerations even when formal regulation does not exist. In addition, the apparent power of informal regulation implies that cost-effective formal systems should be designed to complement, not supplant, community control. In particular: 1) Local communities should not be forced to rely so heavily on visibility when judging environmental performance. Formal regulation should include publication of audited emissions reports from factories; 2) Environmental injustice may be real and important. Many poor, uneducated communities may need extra support from national regulators.; and 3) However, appropriate regulation should strike the right balance between equity and efficiency. Uniform national standards go too far because they eliminate all the natural and legitimate regional diversity that is also reflected in informal arrangements.Public Health Promotion,Environmental Economics&Policies,Water and Industry,Sanitation and Sewerage,Water Conservation,Environmental Economics&Policies,Water and Industry,TF030632-DANISH CTF - FY05 (DAC PART COUNTRIES GNP PER CAPITA BELOW USD 2,500/AL,Sanitation and Sewerage,Urban Services to the Poor

Rafael and J. Vidal cols (1 male, 4 females — INPA).</p> <p> <b>Geographical distribution.</b> Nicaragua, Brazil * (Amazonas; Fig. 3).</p> <p> <b>Remarks.</b> In Nicaragua, type specimens were collected mainly on a coffee farm on the mountainside, at an altitude of about 4.000m, next to a dense cloud forest above and a predominantly pine forest below (Wheeler 1956). The Brazilian specimens were collected in the Pico da Neblina Mountain, the highest mountain in the Brazilian Amazon region (2.995m).</p> <p> <b>Discussion.</b> Marques & Rafael (2016) found a female specimen from Peru that they considered very similar to <i>L. infumata</i>, but which presented some differences in relation to the description of this species, mainly in the size of the triangular spot of the scutum: the triangular spot of <i>L. xantha</i> is longer, occupying almost the entire length of the scutum, and the coloration of the legs differs between these species (Marques & Rafael 2016, see Figs 34, 47 and 50). The female specimen observed by Marques & Rafael (2016) was examined by us and compared with the Amazonian specimens studied in this work and we concluded that they are not the same species.</p> <p> As <i>Latheticomyia infumata</i> was described from Nicaragua and the specimens studied here were collected in Northern Brazil, at first, we thought they could be different species. However, the female specimens studied here fit Wheeler’s (1956) description and figures, and the only male present in the material was collected together with the females. As such, we here consider them conspecific.</p> <p> Two females of <i>Latheticomyia</i> collected from Ecuador and Southern Brazil and deposited at the Canadian National Collection of Insects, Arachnids, and Nematodes (Ottawa, Ontario, Canada) were analyzed by Hennig (1969). The author states that both specimens agree almost perfectly with the description and illustrations given by Wheeler for <i>L. infumata</i> but differ in the number of scutellar setae. Since <i>L. infumata</i> was described from Nicaragua, Hennig (1969) considered the possibility that they are different species, because the two specimens were collected from two distant localities. Hennig (1969) suggested that there was a group of species very closely related to each other and to <i>L. infumata</i>. Unfortunately, we were unable to study these two cited specimens and, given the doubt raised by Hennig (1969), we considered this the first formal record of <i>L. infumata</i> for Brazil.</p>Published as part of <i>Ale-Rocha, Rosaly & Barros, Luana, 2024, New records of Pseudopomyzidae in Brazil and description of the male of Latheticomyia infumata Wheeler (Diptera: Brachycera), pp. 594-600 in Zootaxa 5399 (5)</i> on pages 595-598, DOI: 10.11646/zootaxa.5399.5.9, <a href="http://zenodo.org/record/10517590">http://zenodo.org/record/10517590</a>
