The Sclerocoelus galapagensis group is defined and revised, including the description of S. galapagensis new species from the Galapagos Islands; S. caribensis new species from the Caribbean and adjacent areas; S. brasilensis new species from Brazil, Ecuador, Colombia, and Panama; S. hemorrhoidal is new species from Ecuador and Venezuela; and S. andensis new species from Argentina, Bolivia, and Venezuela. The south Atlantic species Sclerocoelus subbrevipennis (Frey), new combination, is redescribed as a member of the S. galapagensis group, and is considered the sister species to the rest of the species group. A key to species, character matrix, and cladogram are provided.
A revision of the genus Gymnetina Casey, 1915 (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini)
(2011)
The genus Gymnetina Casey (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini) is redescribed and revised. Three new species and one new subspecies are described: G. borealis Warner and Ratcliffe, G. grossepunctata Ratcliffe and Warner, G. howdeni Warner and Ratcliffe, and G. cretacea sundbergi Warner and Ratcliffe. Gymnetina salicis (Bates), new status, is removed from synonymy with G. cretacea (LeConte), and G. alboscripta (Janson) is transferred from Gymnetis MacLeay to Gymnetina becoming Gymnetina alboscripta (Janson), new combination. Redescriptions of previously known species, a key for identification, and illustrations of the six species are provided. A brief biogeographical analysis suggests that ancestral taxa dispersed northwards from Guatemala and Mexico to the southwestern United States.
Motyxia Chamberlin is comprised of eight species of bioluminescent xystocheirine millipeds in which the gonopodal solenomere arises at different positions, from basally and subbasally on the acropodite to being fused with the companion acropodal branch and detaching proximad or near midlength. Previous synonymies of Amplocheir Chamberlin and LuminodeslnllS Loomis and Davenport under Motyxia are confirmed as is its assignment to the tribe Xystocheirini, which is redefined. Component species are 111. Iwnw Chamberlin, the type species, monica Chamberlin, sequoiae (Loomis and Davenport), tularea (Chamberlin), sequoia (Chamberlin), pior Chamberlin, porrecta Causey and Tiemann, and tiemanni Causey. Motyxia sequoia is comprised oftwo races, the nominate and sequoia alia Causey and Tiemann; sequoia ollae Causey and Tiemann is properly a subspecies of tularea. 1I1otyxiapiorform secea is an invalid name without standing in nomenclature, and M. tejona Chamberlin, and M. expansa and exilis, both by Loomis, are placed in synonymy under M. monica, the oldest name for the southernmost species, as Polydesllws dissectus Wood is referrable to Xystocheir Cook. The bioluminescence is a continuous, neon-white glow of the entire dorsal surface including the antennae and legs. Its visibility at night suggests a warning function analogous to aposematic coloration. The phenomenon may observe a circadian rhythm, and controlled photoperiod experimentation may be productive.
Background: Kyrgyzstan, where HIV is concentrated in prisons and driven by injection drug use, provides a prison-based methadone maintenance therapy program as well as abstinence-oriented therapeutic community based on the 12-step model called the “Clean Zone.” We aimed to qualitatively assess how prisoners navigate between these treatment options to understand the persistence of the Clean Zone despite a lack of evidence to support its effectiveness in treating opioid use disorders.
Methods: We conducted an analysis of policy documents and over 60 h of participant observation in February 2016, which included focus groups with a convenience sample of 20 therapeutic community staff members, 110 prisoners across three male and one female prisons, and qualitative interviews with two former Clean Zone participants. Field notes containing verbatim quotes from participants were analyzed through iterative reading and discussion to understand how participants generally perceive the program, barriers to entry and retention, and implications for future treatment within prisons.
Results: Our analyses discerned three themes: pride in the mission of the Clean Zone, idealism regarding addiction treatment outcomes against all odds, and the demonization of methadone.
Conclusion: Despite low enrollment and lack of an evidence base, the therapeutic community is buttressed by the strong support of the prison administration and its clients as an “ordered” alternative to what is seen as chaotic life outside of the Clean Zone. The lack of services for Clean Zone patients after release likely contributes to high rates of relapse to drug use. The Clean Zone would benefit from integration of stabilized methadone patients combined with a post-release program.
Extreme economic effects globally of various populations of the whitefly Bemisia tabaci (Gennadius)
(Hemiptera: Aleyrodidae) led to an in depth study of the morphology of that species as well as that of
numerous other species of whiteflies in the genus Bemisia Quaintance and Baker and other similar appearing
species. The data collected are presented here as illustrations of the puparia (fourth instar nymphal stages)
and discussions of morphology as it relates to species and generic separations within this closely knit group
of insects. A brief history of the pest outbreaks of B. tabaci is given and an overview of the important
morphological characteristics of aleyrodine whiteflies is provided. Each of the eighty illustrations is
accompanied by a discussion of the more important aspects of morphology.
This paper investigates the class of Tree-Tuple MCTAG with Shared Nodes, TT-MCTAG for short, an extension of Tree Adjoining Grammars that has been proposed for natural language processing, in particular for dealing with discontinuities and word order variation in languages such as German. It has been shown that the universal recognition problem for this formalism is NP-hard, but so far it was not known whether the class of languages generated by TT-MCTAG is included in PTIME. We provide a positive answer to this question, using a new characterization of TT-MCTAG.
Num dos artigos, relativos à história dos Ovimbundu, apresentamos três hipóteses sobre a possível origem deste grupo étnico, tendo-nos inclinado, depois de apresentarmos alguns factos, para a hipótese para nós a mais defensável segundo a qual os Ovimbundu descendem dos autores das pinturas rupestres de Caninguiri que, através de um processo de aculturação e miscigenação, foram adquirindo traços dos outros grupos bantu, chegados de paragens e latitudes longínquas. Os mitos possuem uma importância capital, porquanto a análise das narrativas permite não só resgatar elementos susceptíveis de subsidiar a análise de factos históricos (complementando as fontes escritas), como também auxiliar na identificação de elementos culturais com vista à construção da identidade de um determinado grupo étnico.
A origem dos Ovimbundu tem sido motivo de estudos apaixonados por parte de vários historiadores. Uma das razões tem a ver com o facto de se tratar de um grupo étnico que marcou (e continua a marcar), de modo profundo, a história económica, social, política e cultural da porção de território que hoje se chama Angola.
Als die amerikanische Rockband Matchbox Twenty im Jahr 2004 nach dem Start ihres Albums More Than You Think You Are auf Tour durch die Vereinigten Staaten gingen, beschlossen sie, der Tour einen Konzertfilm folgen zu lassen. Er wurde unter dem Titel SHOW: A NIGHT IN THE LIFE OF MATCHBOXTWENTY als Doppel-DVD veröffentlicht.
