Decentralization and fuel subsidies
No full textThis is the author accepted manuscript. The final version is available from Elsevier via the DOI in this recordThis paper explores the role of decentralization in explaining variation in fuel subsidies across countries. Using panel data over the period 1998-2008 and for 108 countries, it emerges that the effect of ‘decentralization’ (taken to be an increase in the number of government levels) broadly decreases both diesel and gasoline subsidies, with this effect being more pronounced when the level of political accountability is low. For developing countries, for which political accountability is low, decentralization decreases gasoline and diesel subsidies by at least 6.98% and 12.99%, respectively. For developed countries, for which political accountability is high, decentralization does not have any impact on both gasoline and diesel. What this evidence points to is that in developing economies, where voters are poorly informed and accountability is low, decentralization appears to be associated with lower fuel subsidies.Leonzio Rizzo thankfully acknowledges financial support from the Spanish Ministry of Economy and Competitiveness (ECO2012-37873) and also from FIR 2016

Translating cognitive neuroscience to the driver's operational environment: A neuroergonomic approach
No full textNeuroergonomics provides a multidisciplinary translational approach that merges elements of
neuroscience, human factors, cognitive psychology, and ergonomics to study brain structure and
function in everyday environments. Driving safety, particularly that of older drivers with cognitive
impairments, is a fruitful application domain for neuroergonomics. Driving makes demands
on multiple cognitive processes that are often studied in isolation and so presents a useful
challenge in generalizing findings from controlled laboratory tasks to predict safety outcomes.
Neurology and the cognitive sciences help explain the mechanisms of cognitive breakdowns
that undermine driving safety. Ergonomics complements this explanation with the tools for systematically
exploring the various layers of complexity that define the activity of driving. A variety
of tools, such as part task simulators, driving simulators, and instrumented vehicles, provide a
window into cognition in the natural settings needed to assess the generalizability of laboratory
findings and can provide an array of potential interventions to increase driving safety.
Overview of neuroergonomics with respect to driving
Neuroergonomics is the study of brain and behavior
at work (Parasuraman, 2003; Parasuraman & Rizzo,
2007). This multidisciplinary field merges the principles
and practice of neuroscience and ergonomics
to study brain structure and function in everyday
environments. Whereas neuroscience and cognitive
psychology have tended to focus on the neural structures
and mental processes underlying cognition in
controlled laborator

Dummynet and Forward Error Correction
No full textIn this paper we present a couple of tools developed by the author on FreeBSD, and available from the author's Web page in source format. The first one, called dummynet, is a tool designed for the performance evaluation of network protocols and applications. Despite its original design goal, there has been a lot of interest on using dummynet as a bandwidth manager in network servers. dummynet simulates the effect of finite queues, bandwidth limitations, and queueing delays, and is embedded in the protocol stack of the host, allowing even complex experiments to be run on a single machine, using existing applications and protocol implementations. The second tool is a software implementation of an erasure code especially suited for use in network protocols. Erasure codes are used in Forward Error Correction (FEC) techniques to reduce or remove the need for retransmissions in presence of communication errors. FEC has been rarely used in network protocols, because of the encoding/decoding o..

Diagnosis. Proboscis with 10 pairs of distal papillae, circa 20 subdistal papillae in rows, each row with 3–5 papillae, and unpaired median papilla absent; prostomium with characteristic pigmentation pattern, a central spot, a pair of small eyes, and another pair embedded on anterior segments (fourth parapodium). Description. Specimens ranging from 5–22 mm long and 0.6–1 mm wide; with 12–69 chaetigers; some specimens incomplete. Description based on the complete holotype (UERJ 5823) in three parts, with 73 chaetigers, 21.5 mm long, and 0.8 mm wide (excluding chaetae). Body long and slender. Prostomium with anterior and lateral edges slightly rounded; small spot on dorsal central portion (Figure 3 A–B). Frontal pair of antennae and ventral pair of palps present. One pair of small subdermal eyes (Figure 3 B) located at base of first chaetiger, near posterolateral edge of prostomium, and another pair embedded on anterior segments (fourth parapodium), occasionally not visible (when stained) (Figure 3 B). Proboscis with 10 pairs of distal papillae; circa 20 rows, each row with 3-5 subdistal papillae. Pair of rounded nuchal organs situated on first chaetiger. First parapodia well delimited, rudimentary and positioned frontally (Figure 3 A–B); dorsal and ventral cirri short, slender and rudimentary, as are notopodial and neuropodial lobes. Ventral mouth opening occupying chaetigers 1 to 3. Interramal branchiae curved inward, present from chaetiger 3 (Figure 3 C–E); decreasing in size toward posterior region until they disappear in final portion of body. Notopodial and neuropodial preacicular lobes rounded, underdeveloped; acicular lobe small and pointed, slightly larger than preacicular; postacicular lobe larger than others, rounded, well developed and translucent (Figure 3 C–E). Notopodia less developed than neuropodia. Dorsal cirri slender, short; ventral cirri conical and developed, but short (Figure 3 C–E). Space between notopodia and neuropodia decreases gradually toward posterior chaetigers. Notopodial and neuropodial preacicular chaetae of three kinds: short and barred (Figure 8 B), short and flattened (Figure 8 C), and short and serrulate; postacicular chaetae from middle of body of two kinds: long and serrulate (Figure 8 D), and long capillary (Figure 8 A). Lyrate chaetae present on all parapodia, but in larger numbers from middle region. Pygidium rounded, small, with short pygidial cirrus. Remarks. The new species resembles Aglaophamus uruguayi Hartman, 1953, from Uruguay: both have a pair of subdermal eyes on the posterior margin of the prostomium, the proboscis with 20 rows of subdistal papillae, and chaetae of the same type. In A. uruguayi the rows of subdistal papillae contain 6 to 9 papillae each, a middorsal unpaired papilla is present, and the interramal branchiae start from chaetiger 4. Unlike the other species described from Brazil, Aglaophamus fabrun sp. nov. has the proboscis with 20 subdistal papillae in rows of 3–5, and lacks an unpaired median papilla; also, the prostomium has characteristic pigmentation, with a central dorsal spot, a feature not present in other Brazilian species of this genus. The nervous system appears as two small dark subdermal eyes located at the basis of chaetiger 4, but cannot be seen in all specimens, especially when they are stained and /or juveniles. Etymology. The species name “ fabrun ’ is dedicated to Fatima Lobôsco Bizzo (“ fa ”) and Bruno Bizzo Franco (“ brun ”), respectively, the mother and brother of the first author, combining the first letters of each name. Distribution. Known only from the Campos Basin, Brazil, in depths of 65– 73 m.Published as part of Franco, Natália Bizzo & Rizzo, Alexandra E., 2016, Nephtyidae (Annelida: Polychaeta) from the Campos Basin, including two new species and a new record, pp. 291-308 in Zootaxa 4114 (3) on pages 295-296, DOI: 10.11646/zootaxa.4114.3.5, http://zenodo.org/record/26458

Diagnosis. Interramal branchiae from parapodium 5, and basal papillae starting on chaetiger 6. Description. Based on incomplete holotype in three parts, with 86 chaetigers, measuring 18.5 mm long and 1.1 mm wide (excluding chaetae). Remaining specimens with 10–44 chaetigers, ranging between 1–5.7 mm long and 0.5–0.7 mm wide (excluding chaetae); all are incomplete except one specimen (UERJ 4772). Body slender, rectangular and wider in anterior than posterior region. Prostomium with posterior edge rounded, upper right and left corners rounded, anterior edge slightly rounded, and with slight central dorsal depression (Figure 5 A–B). Antennae and eye spots absent. Nuchal organs digitiform and long (Figure 5 A–B). Pair of ventral palps, each with digitiform papilla similar to nuchal organs. Parapodium 1 little developed, projected frontally (Figure 5 A–B); dorsal and ventral cirri short. Interramal branchiae starting from parapodia 5, curved inward and well developed, becoming longer from median region of body (Figure 5 C–E). All specimens are incomplete, except one paratype (UERJ 4772), in which branchiae continue to end of body. Basal papillae short and sometimes difficult to see, located on upper part of each branchia (Figure 5 D), from chaetiger 6. Dorsal cirri short and foliaceous with rounded tips on first 4 chaetigers, becoming long and digitiform on following chaetigers (Figure 5 C–E). Dorsal cirri occupying up to half of interramal space on anterior parapodia and 2 / 3 of interramal space from median parapodia. Ventral cirri well developed and similar to dorsal cirri, with base broader than tip, becoming longer and digitiform from middle region (Figure 5 C–E). Notopodia with preacicular lobe rounded and little developed; acicular lobe conical and larger than preacicular lobe; postacicular lobe translucent, rounded and larger than the others; becoming longer and tapered from middle region; narrower and digitiform in posterior region (Figure 5 C– E). Neuropodia with preacicular lobe short and rounded; acicular lobe conical and short; postacicular lobe rounded and larger than acicular lobe (Figure 5 C–E). Neuropodial lobe less developed than notopodial lobe, unlike cirri and branchiae which are well developed. Anterior parapodia with notopodial and neuropodial chaetae long and barred, with rough sandpaper-like appearance, in pre-acicular position (Figure 9 A); and long and denticulate, in postacicular position. Posterior parapodia with no barred chaetae. Some short lyrate chaetae (Figure 9 C) in middle region. Barred chaetae decreasing in number from median parapodia until they disappear in posterior parapodia, and denticulate chaetae occurring in larger numbers. One or 2 aciculae per acicular lobe. Remarks. The new species differs from the others in a set of characteristics including the interramal branchiae from parapodium 5; basal papillae on the upper part of each branchia, from chaetiger 6; and prostomium rounded, with a slight central dorsal depression. In contrast, Inermonephtys brasiliensis Martin, Gil & Lana, 2009, also described from Brazil, has the interramal branchiae from chaetiger 3 and the basal papillae from chaetiger 5; the prostomium pentagonal, long and with the anterior edge straight; and spinulose chaetae. Inermonephtys soldius sp. nov. is the only member of its genus with interramal branchiae emerging from the 5 th parapodia. The barred chaetae with a rough surface are similar to the chaetae found in the glycerid Glycerella magellanica (McIntosh, 1885), see Miranda et al. (2014). Etymology. The species name “ soldius ” is dedicated to Solange (“ sol ”) and Diomar (“ dius ”), the grandmother and grandfather of the first author, combining the first part of each name. Distribution.
