Madeline Leininger theory integrated into the clincial practice Essay

Madeline Leininger theory integrated into the clincial practice - Essay Example Cultural care and universality was identified as being the missing link between the nursing profession and what was actually done in practice (Leininger, 1988). Creating an environment that is culturally acceptable for a patient will lead to a better experience in the hospital (Shaner, n.d.) One of the most important landmarks in the profession of nursing was the establishment of theories to guide the nursing profession and provide the framework for this profession (Leininger, 1988). The concept of ‘care’ as put forth by Leininger was accepted and wrought into the framework of the theories that guide the nursing profession (Shaner, n.d; Leininger, 1988). The theory of care is now a firm fixture in the nursing profession. Nursing students are taught to emphasise on ‘caring’ and accept that being sensitive to a person’s culture will lessen the gap between healthcare professionals and the patients they treat (Leininger, 1988). To conclude, Leininger came up with the concept of caring in the nursing practice which includes the ideas that understanding the culture and environment that a person comes from is vital in providing care. These ideas have now been firmly accepted in to the nursing profession and students are taught these guidelines. Shaner, H. (n.d).

Using Newton Method of Optimization - Coursework Example On the other hand, if a constrained optimization is done (for example, with Lagrange multipliers), the problem may become one of saddle point finding, in which case the Hessian will be symmetric indefinite and the solution of xn+1 will need to be done with a method that will work for such, such as the LDLT variant of Cholesky factorization or the conjugate residual method. There also exist various quasi-Newton methods, where an approximation for the Hessian (or its inverse directly) is built up from changes in the gradient. If the Hessian is close to a non-invertible matrix, the inverted Hessian can be numerically unstable and the solution may diverge. In this case, certain workarounds have been tried in the past, which have varied success with certain problems. One can, for example, modify the Hessian by adding a correction matrix Bn so as to make Hf(in) + Bn positive definite. One approach is to diagonalize H f(xn) and choose Bn so that H f(xn) + Bn has the same eigenvectors as H f(xn), but with each negative eigenvalue replaced by Ï µ > 0.
