Ministers as strategic political leaders? : Strategic political steering after NPM reforms in Finland

This study explores strategic political steering after the New Public Management (NPM) reforms, with emphasis on the new role assigned to Government ministers in Finland. In the NPM model, politicians concentrate on broad, principal issues, while agencies have discretion within the limits set by politicians. In Finland, strategic steering was introduced with Management by Results (MBR), but the actual tools for strategic political steering have been the Government Programme, the Government Strategy Portfolio (GSP) and Frame Budgeting. This study addresses these tools as means of strategic steering conducted by the Cabinet and individual ministers within their respective ministries. The time frame of the study includes the two Lipponen Cabinets between 1995 and 2003. Interviews with fourteen ministers as well as with fourteen top officials were conducted. In addition, administrative reform documents and documents related to strategic steering tools were analysed. The empirical conclusions of the study can be summarised as follows: There were few signs of strategic political steering in the Lipponen Cabinets. Although the Government Programmes of both Cabinets introduced strategic thinking, the strategic guidelines set forth at the beginning of the Programme were not linked to the GSP or to Frame Budgeting. The GSP could be characterised as the collected strategic agendas of each ministry, while there was neither the will nor the courage among Cabinet members to prioritise the projects and to make selections. The Cabinet used Frame Budgeting mainly in the sense of spending limits, not in making strategic allocation decisions. As for the GSP at the departmental level, projects were suggested by top officials, and ministers only approved the suggested list. Frame Budgeting at the departmental level proved to be the most interesting strategic steering tool from ministers viewpoint: they actively participated in defining which issues would need extra financing. Because the chances for extra financing were minimal, ministers had an effect only on a marginal share of the budget. At the departmental level, the study shows that strategic plans were considered the domain of officials. As for strategies concerning specific substances, there was variation in the interest shown by the ministers. A few ministers emphasised the importance of strategic work and led strategy processes. In most cases, however, officials led the process while ministers offered comments on the drafts of strategy documents. The results of this study together with experiences reported in other countries and local politics show that political decision-makers have difficulty operating at the strategic level. The conclusion is that politicians do not have sufficient incentive to perform the strategic role implied by the NPM type of reforms. Overall, the empirical results of the study indicate the power of politics over management reforms.

Common underlying steering curves for motorcycles in steady turns

We study the steady turn behaviours of some light motorcycle models on circular paths, using the commercial software package ADAMS-Motorcycle. Steering torque and steering angle are obtained for several path radii and a range of steady forward speeds. For path radii much greater than motorcycle wheelbase, and for all motorcycle parameters including tyre parameters held fixed, dimensional analysis can predict the asymptotic behaviour of steering torque and angle. In particular, steering torque is a function purely of lateral acceleration plus another such function divided by path radius. Of these, the first function is numerically determined, while the second is approximated by an analytically determined constant. Similarly, the steering angle is a function purely of lateral acceleration, plus another such function divided by path radius. Of these, the first is determined numerically while the second is determined analytically. Both predictions are verified through ADAMS simulations for various tyre and geometric parameters. In summary, steady circular motions of a given motorcycle with given tyre parameters can be approximately characterised by just one curve for steering torque and one for steering angle.

Studies in crystal engineering: Steering ability of fluorine in styrylcoumarins

In continuation of our studies on crystal engineering using fluorine as a steering group, the photobehaviour of di and tri fluoro 4-styrylcoumarins has been examined. It is found that out of the five derivatives, four crystallize into P-packing mode producing syn-HH photodimer upon irradiation whereas the parent hydrocarbon produces an anti K-T dimer. The packing features of the photolabile crystals of 4-(4-fluorostyryl)-6-fluorocoumarin (1), 4-(2,6-difluorostyryl) 6-fluorocoumarin (2) and the photodimer (3a) of 4-(2,6-fluorostyryl)-7-fluorocoumarin (3) have been determined by single crystal X-ray diffraction studies. The stereochemistry of the photodimer of 4-(2-fluorostyryl)-6-fluorocoumarin (4) is deduced based on preliminary X-ray crystallographic data. However, 4-(2,6-difluorostyryl) coumarin (5) is photoinert. The remarkable steering ability of fluorine is established with the molecular packing in the crystal lattice leading to the formation of syn H-H dimer in the above four examples.

Bit Steering In The Minimization Of Control Memory In Microprogrammed Digital-Computers

This correspondence presents an algorithm for microprogram control memory width minimization with the bit steering technique. The necessary and sufficient conditions to detect the steerability of two mutually exclusive sets of microcommands are established. The algorithm encodes the microcommands of the sets with a bit steering common part and also extends the theory to multiple (more than two) sets of microcommands.

INST: An Integrated Steering Framework for Critical Weather Applications

Online remote visualization and steering of critical weather applications like cyclone tracking are essential for effective and timely analysis by geographically distributed climate science community. A steering framework for controlling the high-performance simulations of critical weather events needs to take into account both the steering inputs of the scientists and the criticality needs of the application including minimum progress rate of simulations and continuous visualization of significant events. In this work, we have developed an integrated user-driven and automated steering framework INST for simulations, online remote visualization, and analysis for critical weather applications. INST provides the user control over various application parameters including region of interest, resolution of simulation, and frequency of data for visualization. Unlike existing efforts, our framework considers both the steering inputs and the criticality of the application, namely, the minimum progress rate needed for the application, and various resource constraints including storage space and network bandwidth to decide the best possible parameter values for simulations and visualization.

Optimum steering input determination and path-tracking of all-wheel steer vehicles on uneven terrains based on constrained optimization

In this paper we propose a framework for optimum steering input determination of all-wheel steer vehicles (AWSV) on rough terrains. The framework computes the steering input which minimizes the tracking error for a given trajectory. Unlike previous methodologies of computing steering inputs of car-like vehicles, the proposed methodology depends explicitly on the vehicle dynamics and can be extended to vehicle having arbitrary number of steering inputs. A fully generic framework has been used to derive the vehicle dynamics and a non-linear programming based constrained optimization approach has been used to compute the steering input considering the instantaneous vehicle dynamics, no-slip and contact constraints of the vehicle. All Wheel steer Vehicles have a special parallel steering ability where the instantaneous centre of rotation (ICR) is at infinity. The proposed framework automatically enables the vehicle to choose between parallel steer and normal operation depending on the error with respect to the desired trajectory. The efficacy of the proposed framework is proved by extensive uneven terrain simulations, for trajectories with continuous or discontinuous velocity profile.
