A Comparison Study of An American High School with An International Saudi Arabian High School: Select Variables Include Lessons Plan, Program Assessment, Teacher Credentials, School Culture Provided, and Intramural Activities, 2019
No full textThe purpose of the present research was to identify the differences between some various schooling aspects at one U.S. high school and one girls Kingdom of Saudi Arabia (KSA) high school. In particular, the studied objectives include lessons plan, program assessment, teacher credentials, school culture, and intramural activities. This study was conducted using a mixed-method approach. The obtained results allowed making some specific recommendations that could be considered by the Saudi teachers and school administrations to improve simultaneously the learning process, employee satisfaction, as well as students engagement and motivation. This case study will help to improve both systems through sharing success strategies. Also, it will help families who moved from the United States to Saudi Arabia or the opposite to understand the differences between these education systems for their childrens success. After the data collection and analysis, the researcher concluded that there is no one of these educational systems better than the other. If we could merge these two school systems, we would have the best educational system for students future success.

An analysis of service delivery in the city of Muskegon Heights, Michigan, 1980
No full textThe purpose of this study is to isolate some of the major managerial problems prevalent in the City of Muskegon Heights, Michigan, to elaborate on some of the contributing factors leading to these problems, and to make some recommendations on the fiscal future of this city in view of these problems. No effort is made to deal with the political situation of the City. The writer recognizes that the political problems are indeed serious and that they do impact on the managerial problems. However, the identification and magnification of the political problems require an independent effort altogether.
It is virtually impossible to identify and illuminate of magnify each managerial problem as it effects service delivery. But the major ones are discussed to a considerable extent thus allowing the reader a broad view of this city's municipal operation

Get PDFThis study examines the attitudes of local elected officials regarding quality of life ordinances that impact the street homeless in Atlanta, Georgia, and San Francisco, California. The case study approach was employed. A closed and opened-ended questionnaire was employed to obtain data. Content and aggregate data analysis was also performed. Although the data indicates that there is political representation for the homeless in Atlanta and San Francisco, it is not substantive. That is, even though local government in Atlanta and San Francisco acknowledges the need and its willingness to build additional affordable housing, more energy, time, and resources must be utilized for the creation of affordable housing if governmental figures realistically expect to assist the homeless in securing permanent affordable housing. The data shows, however, that in addition to creating affordable housing, local government in Atlanta and San Francisco has devoted a significant amount of energy, time, and resources to control the behavior of the street homeless. The data analysis also shows that it is the residential and business communities leading the charge for enactment and strong enforcement of quality of life ordinances in both cities. This finding is consistent with Robert DeLeons study of local governance in San Francisco. DeLeon argues that San Francisco politics is best understood within the context of pluralism. My study basically shows that pluralism is at work regarding quality of life ordinances in San Francisco. On the other hand, this finding comes in opposition to what Clarence Stone found in his study of Atlanta: Stone concluded that Atlanta governance is best understood within a regime. Even though my study does not confirm that regime theory is inadequate in explaining governance in Atlanta, it does highlight that the residential and rank and file have a strong and significant voice in ensuring the creation and enforcement of quality of life ordinances in Atlanta. The data analysis also suggests that a relationship exists among council members who believe that the primary cause of homelessness in Atlanta and San Francisco, respectively, stems from personal defects and those who support quality of life ordinances. This finding is consistent when analyzing the attitudes of San Francisco Mayor Willie Brown regarding quality of life ordinances. Of respondents supporting quality of life ordinances, all indicated that the primary cause of homelessness in their respective cities falls within the personal perspective. At the other end of the spectrum, respondents who stated that the primary cause of homelessness is structural indicated opposition to quality of life ordinances

Get PDFThe regulatory role of ROS on CXCR4 expression and function in prostate cancer cells, 2012
Get PDFInactivation of the tumor suppressor phosphatase and tensin liomolog deleted on chromosome 10 (PTEN) is heavily implicated in the tumorigenesis of prostate cancer. Conversely, the upregulation of the chemokine (CXC) receptor 4 (CXCR4) is associated with prostate cancer progression and metastasis. The inactivation of functional PTEN is typically due to genetic and epigenetic modulations, as well as active site oxidation by reactive oxygen species (ROS); likewise ROS upregulates CXCR4 expression. Furthermore, the pathways of CXCR4 and PTEN converge, leading to the promotion and regulation of turnorigenesis, respectively. Based on these observation we hypothesized that, PTEN inhibits CXCR4-mediated functions in prostate cancer cells. This hypothesis was investigated through the following aims: (1) To determine whether PTEN inhibits CXCR4-mediated functions in prostate cancer cells and, (2) To investigate a mechanism by which PTEN function is lost, and CXCR4 function is gained in prostate cancer cells. Upon screening advanced metastatic prostate cancer cell lines for PTEN, identified a loss of expression in PC3 and LNCaP cells, whereas DU145 expressed wildtype PTEN. All three cell lines were positive for surface expression of CXCR4. Reconstitution of PTEN induced a mesenchymal to epithelial-like morphological change and inhibited CXCR4-mediated migration and proliferation in PC3 cells. Downregulation of PTEN by siRNA enhanced the CXCR4-mediated migratory behavior of DU145 cells. By western blot analysis, we observed that PTEN inhibited basal Protein Kinase B (AKT) phosphorylation, but not extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation in PTEN expressing cells. Upon CXCR4 stimulation, PTEN inhibited ERK1/2 phosphorylation, but not phosphorylation of AKT. The CXCR4- mediated migration of PC3 cells was through the ERK1/2 pathway, as confirmed by chemical inhibitors. Based on these studies, we suggest that loss of PTEN permits CXCR4-mediated functions in prostate cancer cells, through the ERK1/2 pathway. We also observed that ROS increased expression of phosphorylated AKT (p -AKT) and phosphorylated ERK1/2 (p-ERK1/2) in DU145 and 22Rv1 prostate cancer cell lines, which was abrogated by the ROS scavenger N-acetyl cysteine (NAC). This study showed that PTEN, was oxidized by ROS accumulation. The oxidized form of PTEN became catalytically inactive, although the expression levels of PTEN remained consistent. Additionally, the ROS-mediated inactivation of PTEN enhanced hypoxia inducible factor lcL (HIF1CL) and CXCR4 expression, and invasion and migration of DU145 cells, in a CXCR4-dependent manner. Interestingly, at the same ROS concentration, 22Rv1 cells did not display mitogenic effects. HIFlo expression decreased in 22Rv1 cells and the cells became apoptotic, despite the increases in AKT and ERK1/2. Taken together, antagonizing CXCR4 and downstream signaling cascades may provide an efficient approach for treating patients with advanced prostate cancer
