Creating learning solutions for executive education programs

Executive education is both a growing and increasingly competitive industry. The traditional business school, once a dominant player in this space, now faces competition from sophisticated and focused consultants and for-profit training specialists offering a variety of face-to-face and on-line instructional vehicles. An abiding question has become ever more prevalent for business schools – are executive education clients getting meaningful, long-term value for their significant investments? Demonstrating value and building capabilities is different for a generic, open enrolment course than for a custom program. This paper proposes a solutions-based approach to the development and implementation of customized executive programs, arguing that the tailored customer focus and the operational rigor of a solutions perspective leads to sustainable and measurable client value both at the individual and corporate level. A case study involving a global high technology company is used to demonstrate the steps required to apply a solutions roadmap. The results show that a solutions approach – carefully and collaboratively undertaken in selected settings – can provide considerable benefits to both client and provider. Further research is proposed to validate and develop the learning points

Steel Industry Slags Compared with Calcium Carbonate in Neutralizing Acid Mine Soil

Author Institution: Ohio State University Agricultural Technical Institute, OHOhio has substantial lands impacted by surface mining for coal and an active steel industry. Steel industry slags have been used as liming compounds for agriculture and acid mine soil reclamation. This 3-year study evaluates slags from Ohio steel mills in greenhouse trials where these materials are compared to reagent grade CaCO3 in their ability to improve plant growth on acid mine soil. The objectives of this study were to evaluate the effectiveness of these materials at two rates of application in raising acid mine soil pH and to address concerns about metals in such slags. Three slags and reagent grade CaCO3 were applied at rates equivalent to 12.5 and 25 g CaCO3 kg-1 soil on acid mine soil (pH = 3.5). Five consecutive crops of oats (Avena sativa L.), wheat (Triticum aestivum L.), corn (Zea mays L.), wheat and soybean (Glycine max (L.) Merr.) were grown and harvested at the seedling stage. The slags and CaCO3 increased yields (P <0.01 level) compared to unlimed control pots. Soil and plant Ca were increased and plant Al and Mn decreased by application of all four materials. The slags increased soil and plant Mg. Particle size of the slags was somewhat coarse which decreased their effectiveness, but overall these slags proved to be satisfactory liming materials. The fineness efficiency developed for carbonate forms of lime may not adequately characterize slag effectiveness. Micronutrient metals including iron were not found to be in excess in plant tissue treated with slags despite the steel slags’ high Fe content

Pathologies in the sticky limit of hard-sphere-Yukawa models for colloidal fluids. A possible correction

A known `sticky-hard-sphere' model, defined starting from a hard-sphere-Yukawa potential and taking the limit of infinite amplitude and vanishing range with their product remaining constant, is shown to be ill-defined. This is because its Hamiltonian (which we call SHS2) leads to an {\it exact}second virial coefficient which {\it diverges}, unlike that of Baxter's original model (SHS1). This deficiency has never been observed so far, since the linearization implicit in the `mean spherical approximation' (MSA), within which the model is analytically solvable, partly {\it masks} such a pathology. To overcome this drawback and retain some useful features of SHS2, we propose both a new model (SHS3) and a new closure (`modified MSA'), whose combination yields an analytic solution formally identical with the SHS2-MSA one. This mapping allows to recover many results derived from SHS2, after a re-interpretation within a correct framework. Possible developments are finally indicated.Comment: 21 pages, 1 figure, accepted in Molecular Physics (2003

Potassium Relationships of Three Ohio Soils

Author Institution: The Ohio State University Agricultural Technical Institute; Department of Agronomy, The Ohio State UniversityThree Ohio soils, Hoytville clay, Brookston silty clay loam, and Wooster silt loam located at various branches of the Ohio Agricultural Research and Development Center, were studied. Bulk samples from each horizon were tested for exchangeable basic cations, pH, sulfuric acid extractable potassium (K+), and particle-size distribution. The surface horizons of each soil were characterized by measurement of cation exchange capacity, quantity-intensity adsorption isotherms for K+ and x-ray diffraction of the clay ( times greater than that for Wooster. Hoytville clay was predominantly illitic while the Brookston and Wooster clays were of a more mixed mineralogical nature. The potassium content and crystallinity of the illite in the Hoytville clay is lower than those of the Brookston and Wooster clays

Logging - one of Mississippi’s most important industries

Logging is extremely important to Mississippi\u27s economy for two reasons. First, the industry is essential in providing wood-based raw materials necessary for many thousands of jobs throughout the state. The industry is the ·:first link in a manufacturing chain that reaches through the state and touches the pulp and paper industry, the sawmill industry. the furniture industry, the building/construction industry. and many others. The industry is also important because of the economic contributions it makes through its own employment and income created. In 1993, the industry contributed an estimated $1.-1-5 billion to Mississippi\u27s economy. and over 11 thousand jobs were directly and indirectly related to logging activities

Economic Impact of Wildlife-Associated Recreation Expenditures in the Southeast United States: A General Equilibrium Analysis

The economic impact of wildlife-associated recreation in the Southeast United States was evaluated using a general equilibrium model. Exogenous demand shocks to the regional economy were based on estimates of expenditures by wildlife recreationists on hunting, fishing, and wildlife watching activities. Counterfactual simulations were carried out, making alternative assumptions about labor and capital mobility and their supply. Without wildlife-associated recreation expenditures, regional employment would have been smaller by up to 783 thousand jobs, and value added would have been $22 to$48 billion less. These findings underscore the significance of regional factor market conditions in economic impact and general equilibrium analysis.general equilibrium modeling, input-output analysis, regional economic impact, wildlife-associated recreation activities, Resource /Energy Economics and Policy, R13, R15, Q26,

The High-Order-Multiplicity of Unusually Wide M-dwarf Binaries: Eleven New Triple and Quadruple Systems

M-dwarfs in extremely wide binary systems are very rare, and may thus have different formation processes from those found as single stars or close binaries in the field. In this paper we search for close companions to a new sample of 36 extremely wide M-dwarf binaries, covering a spectral type range of M1 to M5 and a separation range of 600 - 6500 AU. We discover 10 new triple systems and one new quadruple system. We carefully account for selection effects including proper motion, magnitude limits, the detection of close binaries in the SDSS, and other sample biases. The bias-corrected total high-order-multiple fraction is 45% (+18%/-16%) and the bias-corrected incidence of quadruple systems is < 5%, both statistically compatible with that found for the more common close M-dwarf multiple systems. Almost all the detected companions have similar masses to their primaries, although two very low mass companions, including a candidate brown dwarf, are found at relatively large separations. We find that the close-binary separation distribution is strongly peaked towards < 30AU separations. There is marginally significant evidence for a change in high-order M-dwarf multiplicity with binding energy and total mass. We also find 2-sigma evidence of an unexpected increased high-order-multiple fraction for the widest targets in our survey, with a high-order-multiple fraction of 21% (+17%/-7%) for systems with separations up to 2000AU, compared to 77% (+9%/-22%) for systems with separations > 4000AU. These results suggest that the very widest M-dwarf binary systems need higher masses to form or to survive.Comment: 11 pages, 14 figures, accepted for publication in Ap
