A SIMPLE method for solving problems involving steady flow of grease in pipes or tubing is being developed by the NLGI Subcommittee on Grease Dispensing in Central Systems. The method, based largely on a 1964 NLGI Annual Meeting paper, uses a graphical presentation of the Poiseuille equation for laminar flow. For this purpose, the Subcommittee has prepared charts that are direct reading in pressure drop and flow rate for pipe and tubing sizes commonly used in centralised systems and in transfer of grease from one point to another. The user of the charts must know the apparent viscosity characteristics of the particular grease of interest to him. When these data are plotted on the proposed NLGI chart as lines of shear stress vs. shear rate at constant temperature, various types of flow problems can be solved by drawing a few straight lines on the chart. Since the apparent viscosity is equal to the shear stress divided by the shear rate, the shear stress is found by multiplying each apparent viscosity value by its corresponding shear rate.

Policy-capturing is an experimental technique potentially capable of providing powerful insights into the cognitive bases of work-related decision processes by revealing actors’ “implicit” models of the problem at hand, thereby opening up the “black box” of managerial and organizational cognition. This chapter considers the strengths and weaknesses of policy-capturing vis-à-vis alternative approaches that seek to capture, in varying ways, the inner workings of people’s minds as they make decisions. It then outlines the critical issues that need to be addressed when designing policy-capturing studies and offers practical advice to would-be users concerning some of the common pitfalls of the technique and ways of avoiding them.

This paper uses a laboratory experiment to examine the effect of accountability pressure as a monitoring control tool to mitigate subordinates' propensity to create budgetary slack. The results suggest that budgetary slack is (lowest) highest when accountability pressure is (present) absent under a private information situation. The results further reveal that accountability pressure is positively associated with subordinates' perceived levels of honesty, which in turn is negatively associated with budgetary slack creation. The findings of this paper have important theoretical and practical implications for budgetary control systems design.

Strategic decision making influences organizational performance. However, close examination of this relationship reveals a subtle paradox. It appears that the products of strategic decision making, all of which are necessary for enhanced organizational performance, do not peacefully coexist. Conflict seems to be the crux of this conundrum. As such, a better understanding of conflict's effects on strategic decision making is needed This paper integrates a multidimensional conceptualization of conflict Into a model of strategic decision making and organizational performance and develops propositions to guide empirical study of the effects of conflict on strategic decision making.

Failure to rescue events, or events involving preventable deaths from complications, are a significant contributor to inpatient mortality. While many interventions have been designed and implemented over several decades, this patient safety issue remains at the forefront of concern for most hospitals. In the first part of this study, the development and implementation of one type of highly studied and widely adopted rescue intervention, algorithm-based patient assessment tools, is examined. The analysis summarizes how a lack of systems-oriented approaches in the design and implementation of these tools has resulted in suboptimal understanding of patient risk of mortality and complications and the early recognition of patient deterioration. The gaps identified impact several critical aspects of excellent patient care, including information-sharing across care settings, support for the development of shared mental models within care teams, and access to timely and accurate patient information.

This chapter describes the use of several system-oriented design and implementation activities to establish design objectives, model clinical processes and workflows, and create an extensible information system model to maximize the benefits of patient state and risk assessment tools in the inpatient setting. A prototype based on the product of the design activities is discussed along with system-level considerations for implementation. This study also demonstrates the effectiveness and impact of applying systems design principles and practices to real-world clinical applications.

Teams in extreme and disruptive contexts face unique challenges that can undermine coordination and decision-making. In this study, we evaluated how affective differences between team members and team process norms affected the team's decision-making effectiveness.

Teams were placed in a survival simulation where they evaluated how best to maximize the team's survival prospects given scarce resources. We incorporated multisource and multirater (i.e., team, observer, and archival) data to ascertain the impacts of affect asymmetry and team process norms on decision-making effectiveness.

Results suggest that teams with low positive affect asymmetry and low process norms generate the most effective decisions. The least effective team decision performance occurred in teams characterized by high variance in team positive affectivity (high positive affect asymmetry) and low process norms. We found no similar effect for teams with high process norms and no effect for negative affect asymmetry, however, irrespective of team process norms.

These findings support the affect infusion model and extend cognitive resource theory, by highlighting how affect infusion processes and situational constraints influence team decision-making in extreme and disruptive contexts.
