The High Plateau is a rather ill-defined region occupying the south-eastern portion of Brazil. It rises abruptly from the south-east coast but slopes off very gradually to the north and west. In consequence the rivers flowing north and west are of great length and importance in navigation. Those flowing south are useless for navigation though of great importance for water power. An interesting exceptional river is the Parahyba flowing east and parallel to the south-east coast-line curve. The geology of the whole region is essentially granite and gneiss with curiously metamorphosed quartzites and schists. The accompanying map was made by the writer during some explorations carried out over this region in 1919, and as some of the points studied and already published (1), (2) were new and surprising to geological science, the following general description is added.

Kawasan pesisir timur pulau Natuna Basar memiliki garis pantai yang bervariasi, dari pantai berpasir, pantai berbatu hingga pantai berbakau. Tipe pantai barbakau hanya menempati pada kawasan muara-muara sungai yang sangat dangkal dan berlumpur. Sedangkan pantai berpasir adalah tipe pantai yang mendominasi kawasan pesisir timur pulau Natuna Besar, memanjang dari utara hingga selatan. Pantai berbatu adalah pesisir pantai dengan bongkah granit yang tersebar di kaki Gunung Ranai. Sebaran bongkah granit secara tidak beraturan dan tumpang tindih di kawasan pesisir menyebabkan garis pantai ini menjadi garis pantai yang bernilai wisata tinggi. Bongkah granit ini adalah bagian dari batholit granit Ranai yang merupakan batuan dasar dari kawasan kepulauan Natuna. Kata kunci : pantai, bakau, wisata, bongkah. East coast of Natuna Besar island has variation beach lines, sandy beach, stony beach and mangrove beach. Apparently type of mangrove beach develops in the river mouths, which are muddy and shallow. Sandy beach dominated eastern coast of Natuna Besar island, distributs form the north to the south coast. Stony beach is a coast with boulders of granite in the foot mountain of Ranai. Distribution of Granite boulders are disorientation and unorganized along the east coast, because of these, the coast line has highly tourism value. Granite boulders are part of batholite Ranai granite which is base rock of Natuna islands. Keywords : coast, mangrove, tourism, boulder.

We report the presence of subfossil dwarf hippopotamuses from the neighbourhood of Berivotra (Mahajanga Basin, NW Madagascar), based on an isolated premolar of Hippopotamus, tentatively referred to <em>H. madagascariensis</em> Guldberg, 1882 or<em> H. lemerlei</em> Grandidier, 1868, two of the three species of the genus known in the Malagasy fossil record. Dwarf hippopotamuses from Madagascar are Holocenic, concentrated on the central upland and near the SW coast, with the exception of a single site on the East coast. Their presence and distribution in the N is poorly documented. The new finding, in a locality about 50 km E-SE to the city of Mahajanga, represents the innermost fossil site respect to the present coast line from the NW of the island, and increases the areal distribution of the genus in the Mahajanga Province.

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.

Large areas of North Island hill country are producing below potential as a result of low fertility and poor pasture composition. Removal of undesirable species and replacement with a higher producing pasture is essential for increased productivity but is difficult to achieve. A development programme is described where the use of glyphosate in close association with oversowing and stock management has allowed rapid pasture establishment, marked increase in carrying capacity and a quick return on investment. Keywords: Pasture establishment, glyphosate, oversowing, white clover, subdivision, productivity.

In late September 2018, multiple generations of Chicago’s storied social movements marched through Chicago’s Lincoln Park neighborhood as part of the sold-out, three-day Young Lords Fiftieth Anniversary Symposium hosted by DePaul University—an institution that, alongside Mayor Richard J. Daley’s administration, had played a sizeable role in transforming Lincoln Park into a neighborhood “primed for development.” Students, activists, and community members—from throughout Chicago, the Midwest, the East Coast, and even as far as Texas—converged to celebrate the history of Puerto Ricans in Chicago, the legacies of the Young Lords, and the promises and possibilities of resistance. As Elaine Brown, former chairwoman and minister of information for the Black Panther Party, told participants in the second day’s opening plenary, the struggle against racism, poverty, and gentrification and for self-determination and the general empowerment of marginalized people is a protracted one. “You have living legends among you,” Brown insisted, inviting us to associate as equals with the Young Lords members in our midst. Her plea encapsulated the ethos of that weekend’s celebrations: “If we want to be free, let us live the light of the Lords.”
