Factors Related to the Implementation of Evidenced-based Practice (EBP) of Nursing Staffing Levels in Hospitals: A Literature Review

The implementation of Evidenced-based practice (EBP) was one of the factors in increasing the quality of health services as an ideal problem-solving approach. The ability of nurses to appliance EBP was influenced by many factors, not only on individual nurses consisting by the support of unit leader and colleague. The purpose of this study was to determine the factors associated with the implementation of EBP at the care room level establishing on the support of coworkers and nursing managers. This writing used a literature review study, from several databases namely PubMed, ProQuest, Google Scholar, and ScienceDirect with a limitation of the last 5 years. 17 journals met the inclusion criteria and the results of a literature review study show: eight journals conclude that the support of colleagues and authority in changing practices affects the implementation of EBP, 13 journals concluded the role of managerial nurses affects the implementation of EBP consisting of leadership support and mentorship including the lack of knowledge and skills of nursing leaders regarding EBP. Data from the collected and identified literature study clearly showed that EBP knowledge and skills of nursing leaders related to EBP are important factors in increasing the implementation of EBP but co-worker factors can be a supporter and also an obstacle to the implementation of EBP if it is not well managed.

Boundary Value Problems for Fractional Differential Equations: Existence Theory and Numerical Solutions

Fractional calculus can be considered as supper set of conventional calculus in the sense that it extends the concepts of integer order differentiation and integration to an arbitrary (real or complex) order. This thesis aims at existence theory and numerical solutions to fractional differential equations. Particular focus of interest are the boundary value problems for fractional order differential equations. This thesis begins with the introduction to some basic concepts, notations and definitions from fractional calculus, functional analysis and the theory of wavelets. Existence and uniqueness results are established for boundary value problems that include, two–point, three–point and multi–point problems. Sufficient conditions for the existence of positive solutions and multiple positive solutions to scalar and systems of fractional differential equations are established using the Guo–Krasnoselskii cone expansion and compression theorems. Owning to the increasing use of fractional differential equations in basic sciences and engineering, there exists strong motivation to develop efficient, reliable numerical methods. In this work wavelets are used to develop a numerical scheme for solution of the boundary value problems for fractional ordinary and partial differential equations. Some new operational matrices are developed and used to reduce the boundary value problems to system of algebraic equations. Matlab programmes are developed to compute the operational matrices. The simplicity and efficiency of the wavelet method is demonstrated by aid of several examples and comparisons are made between exact and numerical solutions.
