Indigenous knowledge: A route to the infusion of sustainable development in education.
Indigenous knowledge is the unique knowledge confined to a particular community, produced in order to cope with agro-ecological and socio-economic environments. The purpose of this study is to explore the perceptions of some educators around the issue of infusing indigenous knowledge embedded in communities such as Nubia in their school curricula similar to what other models in indigenous communities in countries such as Hawaii, Brazil and Australia did to reform their curricula. The research is based on the assumption that a culture- and place-based learning in Nubia can promote the infusion of indigenous knowledge. Foucault\u27s theory of power and knowledge relation is adopted to show how indigenous knowledge could be viewed as a tool of empowerment to indigenous, colonized communities contributing to sustainable development. Nubians, within the framework of this theory, could be seen as colonized people seeking a space to practice their teachings and traditions. Unfortunately, this kind of space is denied in Egypt because Nubian students are subjugated to academic practices created by the colonizing public education system that refuses to absorb their local culture and heritage. This study uses a qualitative research design. Interviews with university professors, students and their parents on the possibility and means of integrating indigenous knowledge into curricula were conducted. There were 20 participants that included ten Nubian students, five Nubian parents of the same students and five academics in three different private universities in Egypt. Data from the interviews were analyzed based on Creswell\u27s suggested steps for data analysis in qualitative research. The results indicate high perceptions of the importance of indigenous knowledge and the possibility of integrating it into curricula. The research indicates that the application and approaches towards education for sustainable development still need more thorough investigation in Egypt. Further attention should be given to integrating place-based learning and hands-on experience into educational curricula to encourage students to adapt to situations similar to those in real life
Tectonic significance of Late Precambrian calc-alkaline and alkaline magmatism in Saint Katherina Area, Southern Sinai, Egypt
Two magmatic rock suites are distinguished in the Late Precambrian basement of the Southern Sinai (NW Arabian-Nubian Shield, Egypt), namely (a) a calc-alkaline suite, and (b) an alkaline suite. The former includes Rutig Volcanics, quartz-diorite, quartz-monzonite and monzogranite, while the latter includes Katherina Volcanics and A-type granites. The minerals and textural features (kink, decussate and foliated textures) of the quartz-diorite reveal that it was subjected to deformation and thermal metamorphism. The Rutig Volcanics and quartz-diorite represent subduction related I-type magma, generated from anatexis of older crust with contribution of mantle-wedge magma. The quartz-monzonite and monzogranite are evolved from hybrid magma due to injection of the partly crystallized granitic magma by more basic melts. The mineralogical and geochemical characteristics of these granites indicate a mildly alkaline character and belonging to transitional magma type on the borderline between the calc-alkaline and alkaline magma. The mafic microgranular enclaves (MME) in the quartz-monzonite and monzogranite represent cooled globules from a dioritic magma mingled with the partly crystalline granitic magma. The association of rapakivi texture with the MME confirms the genetic link between the rapakivi texture and magma mixing. The overall characteristics of the Katherina Volcanics and Atype granite are consistent with within-plate tectonic setting. The Katherina Volcanics are derived from a crustal source with a mantle contribution, whereas A-type granites represent residual melts derived from deeper magma chamber through extreme fractional crystallization process
Innovative Modeling of Outcome in Cardiac Surgery
In the normal heart both left and right ventricle have a valve at the atrio-ventricular connection
and at the ventriculo-arterial connection. In the left ventricle the inflow valve is
the mitral valve and the outflow valve is the aortic valve. In the right ventricle the inflow
valve is the tricuspid valve and the outflow valve is the pulmonary valve. These heart
valves ascertain that blood only flows in one direction through the heart. The valves
are made of strong, thin flaps of tissue, called leaflets. The valves control the blood flow
through the heart by opening and closing the leaflets during the contractions of the
heart.
Heart valve disease occurs when one or more of the heart valves do not work correctly
because of valvular stenosis or valvular regurgitation, or a combination of the two. Valvular
stenosis occurs when a heart valve doesn’t fully open due to stiff or fused leaflets
or when a valve is congenitally too small. This limits the amount of blood that can flow
through the valve. Valvular regurgitation, also known as valvular insufficiency, occurs
when a valve does not close properly. This will lead to blood leaking back through the
valve when it should be closed. All four heart valves can develop stenosis, regurgitation
of a combination of both stenosis and regurgitation. In case heart valve disease is not
treated, it can have negative impact on a person’s quality of life and may even become
life-threatening. During the past decades, great advances in the surgical treatment of
heart valves disease have been achieved. This thesis will focus on the surgical treatment
of aortic and pulmonary valve disease
Market-Orientation and Its Impact on the Performance of Asia Insurance Company in Kerman Province
The key of successes by service providers can be found in their market-orientation. These are organizations which pay more attention to customers and rivals and attempt to provide services with the highest quality. Present paper has studied experimentally the relationship between market-orientation and performance of agencies and brokers of Asia Insurance Company in Kerman province. Here, the scale of market-orientation in service sector is applied. The methodology is field study and the tool to gather information is questionnaire. Factors analysis shows that there are four hidden aspects in the title of market-orientation: customer-orientation, rival-orientation, organizational responsiveness, propensity to customer satisfaction. Findings suggest that customer–orientation and propensity to customer satisfaction have remarkable impacts on performance relative to other aspects. Rival-orientation has lower impact on performance and organizational responsive has an inconsistency relationship with performance
