No full text9. Acacia janzenii Ebinger & Seigler, Southw. Naturalist. 32: 245. 1987. type: Mexico. Tabasco: 9.8 mi. W of Lázaro Cárdenas on hwy. 180, 17 June 1966, D. H. Janzen 515 (holotype, MO; isotypes, BM, CAS, F, GH, MICH, MO, UC, US). Tree to 12 m tall, young twigs dark reddish brown, lightly puberulent. Stipular spines dark brown to black, smooth, terete, densely pubescent with straight, yellowish hairs to 0.5 mm long, asymmetrical, U-shaped with an angle of 30-70°, usually curved around the stem, 30-60 (rarely 80) mm long, 6-9 mm thick near the base. Leaves 150-370 mm long; pinnae 30-60 pairs per leaf, 6-9 mm between pinna pairs; rachis grooved, densely pubescent with yellowish hairs, a columnar to narrowly volcano-shaped gland located at the node of each pinna pair, its apex 0.5-0.7 mm across; petiole densely pubescent, 5-8 mm long. Petiolar glands absent. Leaflets 40-70 pairs per pinna, glabrous, linear, 3-5.5 mm long, 0.6-0.9 mm wide, lateral veins not obvious, only one vein from the base, apex acute, margins ciliate. Inflorescence a densely flowered globose head 4-6 mm across, in clusters of 16-42 in the axil of slightly reduced leaves on normal branches, also located on fertile branchlets to 250 mm long with 16-42 inflorescences in each of 6-12 fascicles that may not be subtended by leaves; peduncles glabrous to lightly puberulent, 7-16 mm long, 0.3-0.7 mm thick, the same thickness throughout; involucre located near the middle of the peduncle, usually 4-lobed. Floral bracts peltate, apex circular, stalk 0.4-0.7 mm long. Flowers sessile, calyx 5-lobed, glabrous, 0.6-1.1 mm long; corolla 5-lobed, glabrous, 1.2-2.1 mm long, about twice as long as the calyx. Legumes not seen, but probably very similar to those of Acacia cookii. Flowering May-July. Distribution. Disturbed habitats, roadsides, pastures, and moist disturbed forests, to 400 m elevation, in Chiapas, Tabasco, and Veracruz, Mexico. Representative specimens. MEXICO. Chiapas: stream bank, lower montane rainforest ridge above Ixtacomitan, 300 m, Breedlove 35053 (MEX, MICH, MO). Tabasco: 9.8 mi. W of Cardenas on hwy. 180, Janzen 515 (MEX). Veracruz: Las Cruces, 250 m, Nevling & Gómez-Pompa 1555 (F). Acacia janzenii is easily distinguished from all other ant-acacias by its asymmetrical stipular spines, which usually curve around the stem and are covered with straight, yellowish hairs to 0.5 mm long. The only other species that commonly has asymmetrical thorns is A. cookii. These two closely related species differ in the petiolar and rachis glands, the type of pubescence on the spines, the leaflet length and width, and the flowering branchlets (see discussion under A. cookii). Janzen (1974) considered this taxon a part of Acacia cookii. However, he noted that specimens from Tabasco and Chiapas, Mexico (herein referred to A. janzenii) differ from typical A. cookii. In particular, he noted that progressing from north (Mexico) to south (Belize, Guatemala, Honduras), there is a change in spine length, a shortening of the fertile branchlets, an increase in the number of inflorescences per axil, an increase in the number of Beltian bodies per leaf, and a higher percentage of plants occupied by ants. Although he suggested that the extremes are clinally connected, our principal component analysis (PCA) suggests that these two species are specifically distinct. No intermediate plants were found, and the characters used for separation (petiolar and rachis glands, spine size, pubescence, leaflet size, fertile branchlets) are as significant as those characters used to distinguish other taxa of ant-acacias. Originally, Acacia janzenii probably was a species of disturbed sites in open forests, particularly landslide scars and stream banks. Most recent collections seen are from roadsides and pastures. Beltian body production in this species is relatively low; usually less than 1/4 of the leaflets contain these bodies. Also, these bodies are usually less than 0.7 mm long. None of the specimens tested positive for cyanide production.Published as part of David S. Seigler & John E.

Is there an energy crisis in America's future?
No full textIn the 1970s the United States suffered through two energy crises as a result of OPEC price hikes, and in response Americans turned to more fuel-efficient cars and other conservation methods, driving down the demand for oil. Between 1985 and 1987 a slowdown in economic growth, conservation by consumers, and a substantial increase in competition amongst producers further weakened OPEC, causing oil prices to fall to even lower levels. However, this changed when OPEC agreed to limit production in the fall of 1986, causing oil prices to rise 50% in just 6 months. As fears mounted that this latest round of price increases would result in another energy crisis, some experts called for government intervention to regulate oil market prices, while others argued that the best response to rising prices was simply to let the invisible hand of the market play its course. In this episode, Fred Smith of the Competitive Enterprise Institute, a free market advocacy group, and Charles Ebinger of the Center for Strategic and International Studies examine the current state of affairs in the world oil market and the question of whether government intervention in the marketplace can prevent future energy crises.Examines the problem of government intervention in the oil market and the sudden rise in oil prices that occurred in 1987
Strain accommodation in transitional rifts: extension by magma intrusion and faulting in Ethiopian rift magmatic segments
No full textActive deformation within the northern part of the Main Ethiopian Rift (MER) occurs within approximately 60 km-long, 20 km-wide ‘magmatic segments’ that lie within the 80 km-wide rift valley. Geophysical data reveal that the crust beneath the <1.9 Ma magmatic segments has been heavily intruded; magmatic segments accommodate strain via both magma intrusion and faulting. We undertake field and remote sensing analyses of faults and eruptive centres in the magmatic segments to estimate the relative proportion of strain accommodated by faulting and magma intrusion and the kinematics of Quaternary faults. Up to half the ?10 km-long normal faults within the Boset-Kone and Fantale-Dofen magmatic segments have eruptive centres or extrusive lavas along their length. Comparison of the deformation field of the largest Quaternary fault and an elastic half-space dislocation model indicates a down-dip length of 10 km, coincident with the seismogenic layer thickness and the top of the seismically imaged mafic intrusions. These relations suggest that Quaternary faults are primarily driven by magma intrusion into the mid- to upper crust, which triggers faulting and dyke intrusion into the brittle upper crust. The active volcanoes of Boset, Fantale and Dofen all have elliptical shapes with their long axes in the direction N105, consistent with extension direction derived from earthquake focal mechanisms. Calderas show natural strains ranging from around 0.30 for Boset, 0.55 for Fantale, and 0.94 for Dofen. These values give extension strain rates of the order of 0.3 microstrain per year, comparable to geodetic models. Structural analyses reveal no evidence for transcurrent faults linking right-stepping magmatic segments. Instead, the tips of magmatic segments overlap, thereby accommodating strain transfer. The intimate relationship between faulting and magmatism in the northern MER is strikingly similar to that of slow-spreading mid-ocean ridges, but without the hard linkage zones of transform faults
United States foreign policy in Angola
No full textFollowing independence from Portugal in 1975, Angola entered a 27 year-long civil war that pitted the Marxist Cuban-backed regime of Jose Eduardo dos Santos and his Popular Movement for the Liberation of Angola (MPLA) against the National Union for the Total Independence of Angola (UNITA), led by Jonas Savimbi. Yet despite the government's Marxist ideology, the dos Santos regime proved eager to do business with American companies, most notably those in the oil industry, and by 1980 taxes and royalties paid by Gulf Oil alone composed roughly one sixth of Angola's GDP. In addition to funding Angolan development projects, these American dollars also helped to foot the bill for Cuban missionaries, putting the Reagan Administration at loggerheads with the American business community. In this episode, guests Dr. Charles Ebinger of the Center for Strategic and International Studies and Dr. Scott Thompson of the Fletcher School of Law and Diplomacy discuss American business interests in Angola as well as U.S. involvement in the country's civil war, a matter complicated by the Clark Amendment of 1976, which prohibited government aid to organizations engaged in paramilitary operations in Angola. Given the Angolan government's communist alignment, should the United States back the anti-Marxist forces of Jonas Savimbi, or should it yield to the interests of the American business community?Examines the conflict between American business interests in Angola and the Reagan Administration's opposition to the Marxist government regime
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
