AbstractDescriptions, a key to species, and distribution maps are presented for the three species of Dissochaetus Reitter 1884 known from America north of Mexico. A lectotype is designated for Dissochaetus oblitus LeConte, which occurs in the eastern deciduous forest biome of the eastern United States and southern Ontario. Dissochaetus arizonensis Hatch occurs in mountain forests from Arizona, New Mexico, and west Texas north to Wyoming. Dissochaetus mexicanus Jeannel is reported for the first time in the United States from montane forests in Big Bend, Texas. All are carrion scavengers. Each species represents a separate northwards colonization from Neotropical ancestors.

Solidago nemoralis, the gray goldenrod, is a polycarpic hemicryptophyte that reproduces vegetatively from branched caudices. This native North American species is morphologically variable throughout its range, and includes an eastern (ssp. nemoralis) and western (ssp. decemflora) race. The eastern subspecies occurs throughout the eastern deciduous forest region of North America and is commonly diploid, though tetraploids do occur throughout. The western race typically occurs on the prairies and is strictly tetraploid. The species occupies riparian habitats, rock outcrops and open fields and roadsides and grows best in well-drained sandy soils in full sunlight. Although the species is weedy in both Canada and the United States it is not noxious. Key words: Solidago nemoralis, gray goldenrod, verge d'or des bois, Asteraceae, Compositae

Cytotype Distribution

Chromosome number determinations were made from 218 populations of Solidago nemoralis collected throughout the range of the species in Canada and the United States. All individuals of ssp. decemflora were tetraploid (2n = 36; 28 populations); these came from the prairies and adjacent eastern deciduous forest states and provinces. The majority of the collections of ssp. nemoralis were diploid (2n = 18; 161 populations) and came from throughout the eastern deciduous forest region of eastern North America. Tetraploids (2n = 36; 29 populations) of ssp. nemoralis were less frequent and occurred scattered across the eastern and northern portions of the range of the subspecies. The cytotype distribution pattern of the two subspecies of Solidago nemoralis is representative of what appears to be a frequent evolutionary strategy in the goldenrods.

The morphology and chromosome number of nine species of Cirsium of eastern North America are considered. Chromosome counts are presented for the first time for C. iowense, 2n = 18; C. lecontei, 2n = 32; C. nuttallii, 2n = 24, 28; C. repandum, 2n = 30; C. smallii, 2n = 34; C. engelmannii, 2n = 20; C. texanum, 2n = 22, 24; C. virginianum, 2n = 28. Additional chromosomes, possibly to be considered as accessories, were found in C. nuttallii, C. engelmannii, and C. texanum. These chromosomes render uncertain the number characteristic of these species. A key to the 26 native and introduced species found in Canada and the United States east of 100° west latitude is presented. The interrelationships of the eastern species and of the species of the western series Undulata are discussed.

Herbaceous Perennial

Symphyotrichum ericoides, the heath aster, is a herbaceous perennial, arising from woody, corm-like rootstocks or herbaceous rhizomes. This facultative upland species occurs in open, dry ground in plains, railway sidings, prairies, ranges, glades, grassy hillsides, dunes, sand bars, river banks, shore salt flats, and thickets. A weed in Canada, and sometimes declared so in the United States and other times not, S. ericoides has an extensive North American distribution, occurring from Nova Scotia and Maine in the east, westward to southern British Columbia, and southward to northern Mexico. No infraspecific taxa are recognized in this treatment of the species. Symphyotrichum novae-angliae, the New England aster, is a herbaceous perennial, arising from thick, short-branched, woody rootstocks. This facultative wetland species occurs in open places such as along roadside ditches and fence rows, on dry ground in plains, prairies and glades, in clearings, meadows and abandoned fields, and along stream banks and swamps, or in moist open or sometimes wooded places. A weed in both Canada and the United States, S. novae-angliae occurs commonly throughout the northern two-thirds of the eastern deciduous forest region of North America and onto the Great Plains. In the east, Nova Scotia populations are likely escaped cultivars, but in the west, isolated natural populations occur from the Black Hills region of South Dakota south to New Mexico. No infraspecific taxa are reco gnized in this treatment of the species. In those habitats where the two species co-occur, the morphologically intermediate F1hybrid S. amethystinum is often found. Key words: Symphyotrichum ericoides, Aster ericoides, Aster multiflorus, heath aster, Symphyotrichum novae-angliae, Aster novae-angliae, New England aster

This chapter is a study of the themes of the New International Economic Order (NIEO). It begins with the notion of justice that had been constructed in imperial law to justify empire and colonialism. The NIEO was the first time a prescription was made for justice in a global context not based on domination of one people over another. In its consideration of the emergence of a new notion of justice in international law, the chapter discusses the reasons for the origins of the NIEO, and goes on to describe the principles of the NIEO and the extent to which they came into conflict with dominant international law as accepted by the United States and European states. Next the chapter deals with the rise of the neoliberal ideology that led to the displacement of the NIEO and examines the issue of whether the NIEO and its ideals have passed or whether they continue to be or should be influential in international law. Finally, the chapter turns to the ideas of the NIEO alongside new efforts at promoting a fuller account of justice by which to justify and evaluate international law.

Age Related

The emergence of age-related chronic diseases within the United States has led to the direct increase of Alzheimer’s disease (AD) as well as other neurological diseases which ultimately contribute to the development of dementia within the general population. To be specific, age-related chronic diseases such as cardiovascular disease, high cholesterol, diabetes, and kidney disease contribute greatly to the advancement and rapid progression of dementia. Furthermore, unmodifiable risk factors such as advancing age and genetics as well as modifiable risk factors such as socioeconomic status, educational attainment, exercise, and diet further contribute to the development of dementia. Current statistics and research show that minority populations such as Hispanic Americans in the United States face the greatest burden of dementia due to the increase in the prevalence of overall population age, predisposing genetics, age-related chronic diseases, low socioeconomic status, as well as poor lifestyle choices and habits. Additionally, Hispanic Americans living within Texas and the rural areas of West Texas face the added challenge of finding appropriate healthcare services. This article will focus upon the research associated with AD as well as the prevalence of AD within the Hispanic American population of Texas and rural West Texas. Furthermore, this article will also discuss the prevalence of age-related chronic diseases, unmodifiable risk factors, and modifiable risk factors which lead to the progression and development of AD within the Hispanic American population of the United States, Texas, and rural West Texas.
