Using the Balanced Scorecard for Ranch Planning and Management:Setting Strategy and Measuring Performance

The key to business success—whether operating a ranch or a Fortune 500 company—lies in management and planning. It’s the ability to have foresight, to carefully evaluate and choose appropriate new concepts and technologies, and to implement a well thought- out plan that complements all aspects of the business. The highly-respected former CEO and chairman of General Electric Jack Welch put it this way: Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion. How does that description apply to you? Are you a visionary business leader for your ranch enterprise? Or can you become one? This manual introduces the “Balanced Scorecard” developed by Dr. Robert Kaplan of the Harvard Business School and Dr. David Norton. The duo authored the book The Balanced Scorecard: Translating Strategy Into Action, and the scorecard format has been used by thousands of global companies and small businesses since the early 1990s when it was initially developed. While this concept may be relatively new to the ranching community, adopters of this approach to management include corporate icons like General Electric, DuPont, Ford Motor Company, IBM, and Walt Disney World. Using the scorecard, a manager can clearly see the things that need to be measured to “balance” different competing parts of the ranch. For example, rather than analyze financial records alone—which are only capable of telling of past events—this approach also takes into account things such as customer relationships, ranch processes, and investment in family members and employees’ learning and growth— all of which can have an impact on future business success. Central to the effectiveness of the Balanced Scorecard is viewing the business (your ranch) from these perspectives and then developing strategies and evaluating outcomes relative to each of those perspectives. By doing so, you can build a stronger base for your future sustainability. To that end, this manual offers a step-by step guide for the ranching industry to adopt the Balanced Scorecard and move toward managing for ranch business success

The effective hyper-K"ahler potential in the N=2 supersymmetric QCD

The effective low-energy hyper-K"ahler potential for a massive N=2 matter in the N=2 super-QCD is investigated. The N=2 extended supersymmetry severely restricts that N=2 matter self-couplings so that their exact form can be fixed by a few parameters, which is apparent in the N=2 harmonic superspace. In the N=2 QED with a single matter hypermultiplet, the one-loop perturbative calculations lead to the Taub-NUT hyper-K"ahler metric in the massive case, and a free metric in the massless case. It is remarkable that the naive non-renormalization `theorem' does not apply. There exists a manifestly N=2 supersymmetric duality transformation converting the low-energy effective action for the N=2 QED hypermultiplet into a sum of the quadratic and the improved (non-polynomial) actions for an N=2 tensor multiplet. The duality transformation also gives a simple connection between the low-energy effective action in the N=2 harmonic superspace and the component results.Comment: 12 pages, LaTeX, one figure and macros include

Coronary sinus ostial occlusion during retrograde delivery of cardioplegic solution significantly improves cardioplegic distribution and efficacy

AbstractThis study documents the gross flow characteristics and capillary distribution of cardioplegic solution delivered retrogradely with the coronary sinus open versus closed. Methods : Five explanted human hearts from transplant recipients were used as experimental models. Hearts served as their own controls and received two doses of warm blood cardioplegic solution, each containing colored microspheres. The first dose was delivered through a retroperfusion catheter with the coronary sinus open and the second dose was delivered with the sinus occluded. Capillary flow was measured at twelve ventricular sites and gross flow was measured by examining coronary sinus regurgitation, thebesian vein drainage, and aortic effluent (nutrient flow). Results : Coronary sinus ostial occlusion allowed for a significant decrease in total cardioplegic flow (1.74 ± 0.40 ml/gm versus 1.06 ± 0.32 ml/gm; p < 0.05) to occur while maintaining an identical intracoronary sinus pressure. Ostial occlusion also resulted in an increase in the ratio of nutrient flow/total cardioplegic flow from 32.3% ± 15.1% to 61.3% ± 7.9% (p < 0.05). A statistically significant improvement in capillary flow was found at the midventricular level in the posterior intraventricular septum and posterolateral right ventricular free wall. This improvement was also documented for the intraventricular septum and right ventricle at the level of the apex. Conclusion : Coronary sinus occlusion during retrograde cardioplegia significantly improves cardioplegic delivery to the right ventricle and posterior intraventricular septum. Furthermore, the technique affords a significant improvement in nutrient cardioplegic flow while reducing the overall volume of cardioplegic solution administered.

Conflict of roles, a conflict of ideas? The unsettled relations between care team staff and independent mental health advocates.

Drawing on a national study of Independent Mental Health Advocacy we explore the social relations of independent advocacy. The study was commissioned by the Department of Health (England) and involved a case study design covering eight different geographies and service configurations, and interviews or focus groups with a total of 289 stakeholders across two phases of inquiry. This paper focuses on analysis of qualitative data relevant to the relationship between mental health care services and independent advocacy services, drawn from interviews with 214 participants in phase two of the study. Discussion of these particular findings affords insights into the working relations of independent advocacy within mental health services beset by reorganizational change and funding cuts, and increasing levels of legally sanctioned compulsion and coercion. We offer a matrix which accounts for the different types of working relationships that can arise and how these are associated with various levels of understanding of independent advocacy on the one hand, and appreciation for the value of advocacy on the other. The discussion is framed by the wider literature on advocacy and the claims by practitioners such as nurses for an advocacy role as part of their professional repertoire

Engineering of Quantum Hall Effect from Type IIA String Theory on The K3 Surface

Using D-brane configurations on the K3 surface, we give six dimensional type IIA stringy realizations of the Quantum Hall Effect (QHE) in 1+2 dimensions. Based on the vertical and horizontal lines of the K3 Hodge diamond, we engineer two different stringy realizations. The vertical line presents a realization in terms of D2 and D6-branes wrapping the K3 surface. The horizontal one is associated with hierarchical stringy descriptions obtained from a quiver gauge theory living on a stack of D4-branes wrapping intersecting 2-spheres embedded in the K3 surface with deformed singularities. These geometries are classified by three kinds of the Kac-Moody algebras: ordinary, i.e finite dimensional, affine and indefinite. We find that no stringy QHE in 1+2 dimensions can occur in the quiver gauge theory living on intersecting 2-spheres arranged as affine Dynkin diagrams. Stringy realizations of QHE can be done only for the finite and indefinite geometries. In particular, the finite Lie algebras give models with fractional filling fractions, while the indefinite ones classify models with negative filling fractions which can be associated with the physics of holes in the graphene.Comment: 14 pages, one figure.
