Evaluation of a Continued Safe Patient and Handling Program

Nursing staff have a high risk of on the job injury from patient handling and movement. Safe Patient Handling and Movement programs help reduce injury through education and training to employees. Programs need to be evaluated regularly to determine if the goals are being met. When a program is not meeting its projected goals, modifications are needed to improve the program and its outcomes. The purpose of this project was to evaluate a continued safe patient handling program. The goals were to provide best evidence from research. Use best evidence to enhance the program. Promote positive behaviors from employees. Reduce healthcare workers injuries related to patient handling and movement. The objectives were to determine if modifications would decrease safe patient injuries. To promote safe patient handling and movement behaviors that is positive from employees. Increase employees comfort, knowledge, and use of minimal lift equipment during patient handling and movement. The outcomes of the program are successful in meeting the goals and objectives. Modifications to the program were introduced and injuries from patient handling decreased by 50% during the implementation period when compared to the post implementation period. Positive behaviors were witnessed and expressed from employees. Employees also expressed they felt they had increased knowledge of the minimal lift equipment and increased comfort with use of the minimal lift equipment

Exploring the Conformational Transitions of Biomolecular Systems Using a Simple Two-State Anisotropic Network Model

Biomolecular conformational transitions are essential to biological functions. Most experimental methods report on the long-lived functional states of biomolecules, but information about the transition pathways between these stable states is generally scarce. Such transitions involve short-lived conformational states that are difficult to detect experimentally. For this reason, computational methods are needed to produce plausible hypothetical transition pathways that can then be probed experimentally. Here we propose a simple and computationally efficient method, called ANMPathway, for constructing a physically reasonable pathway between two endpoints of a conformational transition. We adopt a coarse-grained representation of the protein and construct a two-state potential by combining two elastic network models (ENMs) representative of the experimental structures resolved for the endpoints. The two-state potential has a cusp hypersurface in the configuration space where the energies from both the ENMs are equal. We first search for the minimum energy structure on the cusp hypersurface and then treat it as the transition state. The continuous pathway is subsequently constructed by following the steepest descent energy minimization trajectories starting from the transition state on each side of the cusp hypersurface. Application to several systems of broad biological interest such as adenylate kinase, ATP-driven calcium pump SERCA, leucine transporter and glutamate transporter shows that ANMPathway yields results in good agreement with those from other similar methods and with data obtained from all-atom molecular dynamics simulations, in support of the utility of this simple and efficient approach. Notably the method provides experimentally testable predictions, including the formation of non-native contacts during the transition which we were able to detect in two of the systems we studied. An open-access web server has been created to deliver ANMPathway results. © 2014 Das et al

An organizational approach to comparative corporate governance: Costs, contingencies, and complementarities

This paper develops an organizational approach to corporate governance and assesses the effectiveness of corporate governance and implications for policy. Most corporate governance research focuses on a universal link between corporate governance practices (e.g. board structure, shareholder activism) and performance outcomes, but neglects how interdependences between the organization and diverse environments lead to variations in the effectiveness of different governance practices. In contrast to such ‘closed systems’ approaches, we propose a framework based on ‘open systems’ approaches to organizations which examines these organizational interdependencies in terms of the costs, contingencies, and complementarities of different corporate governance practices. These three sets of organizational factors are useful in analyzing the effectiveness of corporate governance in diverse organizational environments. We also explore how costs, contingencies, and complementarities impact effectiveness of different governance aspects through the use of stylized cases and discuss the implications for different approaches to policy such as ‘soft-law’ or ‘hard law’
