Connecting High School Mathematics and Abstract Algebra

This thesis focuses on the connections between the content covered in college level abstract algebra and high school mathematics courses. The purpose of studying and understanding these connections is in hopes to improve the way concepts are presented at the high school level to give students a deeper understanding of the mathematics. High school mathematics teachers are required to take specific college courses such as abstract algebra before they can teach high school mathematics. However, many teachers do not believe they can use the complex ideas learned in college to teach their students. On the surface, the content from courses like abstract algebra may seem unrelated, but recognizing important links and altering instruction could make college level mathematical ideas seem accessible to the high school students. We will not only study the connections in content, but also examine different ways to teach the content and how this can be beneficial to students

BOOK REVIEW : CLASS, CULTURE AND SPACE: THE CONSTRUCTION AND SHAPING OF COMMUNAL SPACE IN SOUTH THAILAND

Compared with other regions of Thailand, South Thailand has been a somewhat neglected center of research for many decades. Thomas Fraser's classic ethnographic study of the fishing village known as Rusembilan and Louis Golomb's work on ethnicity in the region, supplemented by some political science investigations by Ladd Thomas, Astri Suhrke and others, were conducted in the 1960s and 70s. In the 1980s Muslim scholars in Thailand including Surin Pitsuwan, Arong Suthasasna, Hasan Madmarn, and Chaiwat Satha-Anand contributed major studies that placed the Malay Muslims of South Thailand in their political, religious and cultural contexts. Thai anthropologist Chavivun Prachuabmoh developed models for understanding gender and ethnicity among Malay Muslims, while Uthai Dulyasakem focused on educational institutions in the region. Studies lagged on South Thailand, however, in comparison with those on Central, North, and Northeast Thailand.

Evaluation of Invasive Retrofitting Interventions on an Unreinforced Masonry Heritage Building

The present study case highlights the importance of considering local failures for irregular unreinforced masonry buildings, by means of nonlinear seismic analyses. Simplified seismic assessments based on equivalent frame method were used in order to capture the structural behavior of the National Geological Museum from Bucharest in its initial form and also the current structural layout. The retrofitting works realized in the 1982 were focused on strengthening the transversal masonry walls and on creating horizontal diaphragms to improve the “box behavior” of the building subjected to lateral forces. Retrofitting of unreinforced masonry walls by reinforced concrete jacketing and the replacement of flexible floors by reinforced concrete slabs were previously considered to be effective only though post-earthquake visual inspections of the strengthened elements. The efficiency of past interventions is studied in the present paper through comparisons between the two models in terms of damage patterns, global behavior and also performance levels established function of maximum relative displacements

Constraining long-term denudation and faulting history in intraplate regions by multisystem thermochronology: An example of the Sudetic Marginal Fault (Bohemian Massif, central Europe)

The Rychlebské hory Mountain region in the Sudetes (NE Bohemian Massif) provides a natural laboratory for studies of postorogenic landscape evolution. This work reveals both the exhumation history of the region and the paleoactivity along the Sudetic Marginal Fault (SMF) using zircon (U-Th)/He (ZHe), apatite fission track (AFT), and apatite (U-Th)/He (AHe) dating of crystalline basement and postorogenic sedimentary samples. Most significantly, and in direct contradiction of traditional paleogeographic reconstructions, this work has found evidence of a large Cretaceous sea and regional burial (to >6.5 km) of the Carboniferous-Permian basement in the Late Cretaceous (~95–80 Ma). During the burial by sediments of the Bohemian Cretaceous Basin System, the SMF acted as a normal fault as documented by offset ZHe ages across the fault. At 85–70 Ma, the basin was inverted, Cretaceous strata eroded, and basement blocks were exhumed to the near surface at a rate of ~300 m/Ma as evidenced by Late Cretaceous–Paleocene AFT ages and thermal modeling results. There is no appreciable difference in AFT and AHe ages across the fault, suggesting that the SMF acted as a reverse fault during exhumation. In the late Eocene–Oligocene, the basement was locally heated to <70°C by magmatic activity related to opening of the Eger rift system. Neogene or younger thermal activity was not recorded in the thermochronological data, confirming that late Cenozoic uplift and erosion of the basement blocks was limited to less than ∼1.5 km in the study area

Diglossia and identity in Northeast Thailand: Linguistic, social, and political hierarchy

The paper explores diglossic relations between Central Thai and phasa isan, a variety officially known as a dialect of Thai, but linguistically close to Lao. Phasa isan is spoken by almost one-third of Thailand's population but its speakers in the Northeast are often stigmatized as uneducated and backward. We conducted field research mainly among university students in Ubon Ratchathani, a northeastern border province, by drawing upon data from survey questionnaires, reflective essays, interviews, and field observations. The findings suggest a transitional diglossic relationship in which Central Thai is the High and phasa isan the Low variety. These relationships are discussed in terms of nationalism, social hierarchy, and language maintenance and shift
