The Agulhas Ridge, South Atlantic: the peculiar structure of a fracture zone

The Agulhas Ridge is a prominent topographic feature that parallels the Agulhas-Falkland Fracture Zone (AFFZ). Seismic reflection and wide angle/refraction data have led to the classification of this feature as a transverse ridge. Changes in spreading rate and direction associated with ridge jumps, combined with asymmetric spreading within the Agulhas Basin, modified the stress field across the fracture zone. Moreover, passing the Agulhas Ridges location between 80 Ma and 69 Ma, the Bouvet and Shona Hotspots may have supplied excess material to this part of the AFFZ thus altering the ridges structure.The low crustal velocities and overthickened crust of the northern Agulhas Ridge segment indicate a possible continental affinity that suggests it may be formed by a small continental sliver, which was severed off the Maurice Ewing Bank during the opening of the South Atlantic.In early Oligocene times the Agulhas Ridge was tectono-magmatically reactivated, as documented by the presence of basement highs disturbing and disrupting the sedimentary column in the Cape Basin. We consider the Discovery Hotspot, which distributes plume material southwards across the AAFZ, as a source for the magmatic material

Seismic wide-angle study of accreted Proterozoic crust in southeastern Wyoming

A seismic wide-angle xperiment was conducted in southeastern Wyoming, USA to investigate the seismic character of a postulated Proterozoic magmatic arc south of the suture (Cheyenne Belt) to the Archean Wyoming Province. Recordings from vibrator and dynamite sources with offsets between 34 and 126 km reveal no evidence for Moho reflections. The large-offset recordings contain multicyclic bands of reflective phases from the middle to lower crust. The data were transformed into the intercept ime-ray parameter (~--p) domain to estimate local depth bounds. A subsequent 1D inversion using high-amplitude ~'-p arrivals shows that the reflective part of the crust ranges from the depths of 25 to 40 km. This part of the crust exhibits velocities increasing from about 6.5 to 7.5 km/s. Reflectivity modeling shows that the lower crust might consist of a zone of alternating low- and high-velocity layers with average velocity increasing. The average lower crustal velocity of about 6.9 km/s suggests a predomi-nantly mafic composition with interlayered intermediate to felsic components generating impedance contrasts that cause observable amplitudes from reflections at large offsets but not at clearly pre-critical and near-vertical distances. Our model is consistent with observations of interlayered sequences of gabbroic to ultramafic rocks with more felsic anorthositic and charnockitic rocks in the exposed lower crust of magmatic arc complexes. The lack of wide-angle Moho reflections might be explained by a gradational compositional boundary, or a transitional phase change from granulite to eclogite facies. 1

The Effect of Group Music Therapy on Alleviating Depression in Older Adults

Depression and loneliness are significant psychological symptoms that often go unnoticed in older adults. Group music therapy with older adults provides an opportunity to alleviate depression through shared music making, reminiscing, and forming new connections with other individuals. This paper explores the implications of using music therapy to alleviate depression in an older adult population as found in prior research on this topic, advocating for group music therapy over individual therapy as a means to establish connections during old age

Cognitive Behavioral Therapy for Binge Eating Disorder in Adolescence

Eating disorders are among the most prevalent psychological disorders for the adolescent population. The onset of binge eating disorder (BED) occurs in late adolescence to early adulthood and affects numerous individuals who struggle with identity formation and social development. This paper critiques the efficacy of cognitive behavioral therapy (CBT) in treating binge eating disorder in adolescence. While evidence on the efficacy of this treatment is limited, all research supports the use of cognitive behavioral therapy in treating binge eating disorder. More research on treatment of binge eating disorder must be conducted as adolescence is a crucial time for identity formation

From Augustine to Scalia: Catholic Thought and Capital Jurisprudence in the United States

In April 2009, after baptism, confirmation, and twenty years as a Missouri Synod Lutheran, William Gohl entered the Roman Catholic Church. His reasons for doing so were manifold, but included an attraction to a sense of community in the Mass and the various mysteries of sacramentality, among other things. His time at Regis University sparked an interest in further exploring the topic of capital punishment and contemplating some of the most difficult moral questions it raises facing American society today. This Senior Honors Thesis discusses a novice Catholic and aspiring attorney\u27s study of the Church\u27s teaching on capital punishment and the manner in which the teaching is applied today in the United States. Gohl believes that human life, and the pursuit of the best means of defending and preserving human life, are well worth the effort

Workshop - Amundsen Sea Embayment Tectonic and Glacial History - Programme and Abstracts

Overall Objective: Review existing data and identify priorities for future geoscience research (terrestrial, marine and airborne) in the Amundsen Sea embayment (ASE) region required to develop a better understanding of the past, present and future behaviour of this sector of the West Antarctic Ice Sheet (WAIS). Background: The ASE is the most rapidly changing sector of the WAIS and contains enough ice to raise global sea level by 1.2 m. Over the past few years considerable efforts have been made to acquire new data to improve knowledge of the geological structure, subglacial topography, continental shelf bathymetry and glacial history of this remote region. In this workshop we aim to review the current state of knowledge on the tectonic and glacial evolution of the Amundsen Sea embayment. Particular emphasis will be placed on work that will improve boundary conditions for ice sheet models (e.g. subglacial topography, shelf bathymetry, palaeotopography, heat flow and substrate types) and provide palaeo-data against which model outputs can be compared. There will also be a focus on plans and targets for future scientific drilling that will reveal the history of this sector of the WAIS and its sensitivity to major climate changes

A Literature Review of Parental Involvement in Public Schools from 1994-1999

The purpose of this project was to see how parental involvement affected student achievement and how educators could involve parents at the middle grades and junior/senior high levels. American families and our society have changed dramatically over the past twenty-five years. These changes have had exciting effects on educational processes in schools. It has become a challenge to involve parents in the educational process, especially during the middle, junior and senior high school years. Parents are far more involved in their children\u27s early childhood education than in their later years of schooling (Pryor, 1995). Involvement drops off dramatically when children enter the middle and junior/senior high school. Research studied in this project shows that there is a link between parent involvement and student achievement (Ho Sui-Chi, & Williams, 1996). This project explores research relative to decreased parent involvement, and how this phenomenon is impacting many public schools across the United States. It also explores what schools might do to increase parent involvement and student achievement
