Problem‐solving strategies for small‐scale emerging commercial mango farmers in Venda

This article describes the prevailing farming system of emerging small‐scale commercial mango farmers in the Venda region of the Northern Province of South Africa. Analyses based on intensive group discussions with farmers and prioritisation of their problems using a ‘problem tree/objective tree'framework, as well as comparisons with adjacent commercial mango farmers, enabled the development of operational support strategies. This study followed a new (for South Africa) participative approach. The first step of the Objective Oriented Intervention Planning (OOIP) approach to Logical Framework Analysis (LFA) is a problem tree; the next is to convert the problem tree into an objective tree in order to identify alternative strategies for alleviating constraints and problems. These are then summarised in the LFA matrix. This methodology is described here.     

The optimality of nominal contracts

Summary. This paper presents a model in which agents choose to use money as a medium of exchange, a means of payment, and a unit of account. The paper defines conditions under which nominal contracts, promising future payment of a fixed number of units of fiat money, prove to be the optimal contract form in the presence of either relative or aggregate price risk. When relative prices are random, nominal contracts are optimal if individuals have ex ante similar preferences over future consumption. When the aggregate price level is random, whether from shocks to the money supply or aggregate output, nominal contracts (perhaps coupled with equity contracts) lead to optimal risk-sharing if individuals have the same degree of relative risk aversion. Finally, nominal contracts may be optimal if the repayment of contracts is subject to a binding cash-in-advance constraint. In this case, a contingent contract increases the risk of holding excessive cash balances. Received: March 29, 1996; revised version: February 25, 1997     

Technology Foresight in Companies: From an Indicator to a Network and Process Perspective

Technology foresight is an important activity in companies to meet the challenges of a fast changing environment. The understanding and the concepts of technology foresight have changed during the last decades. Three generations of technology foresight are developed in this paper. In the third generation, technology foresight is an integrated part of strategic management, process-oriented, need- and value-driven and network-dominated. Although this model represents practices in companies, not all elements are included in one firm. This paper is based on interviews in large multinational corporations and a review of the literature.     

Curbing domestic violence: instantiating C–K theory with formal concept analysis and emergent self-organizing maps

We propose a human-centred process for knowledge discovery from unstructured text that makes use of formal concept analysis and emergent self-organizing maps. The knowledge discovery process is conceptualized and interpreted as successive iterations through the concept–knowledge (C–K) theory design square. To illustrate its effectiveness, we report on a real-life case study of using the process at the Amsterdam–Amstelland police in the Netherlands aimed at distilling concepts to identify domestic violence from the unstructured text in actual police reports. The case study allows us to show how the process was not only able to uncover the nature of a phenomenon such as domestic violence, but also enabled analysts to identify many types of anomaly in the practice of policing. We will illustrate how the insights obtained from this exercise resulted in major improvements in the management of domestic violence cases. Copyright © 2010 John Wiley & Sons, Ltd.     

Disinflation in a DSGE perspective: Sacrifice ratio or welfare gain ratio?

When used to examine disinflation monetary policies, the current workhorse dynamic stochastic general equilibrium model of business cycle fluctuations is able to quantitatively account for the main stylized facts in terms of recessionary effects and sacrifice ratio. We complement the transitional analysis of the short-run costs with a rigorous welfare evaluation and show that, despite the long-lasting economic downturn, disinflation entails non-zero overall welfare gains.     

Die Mittelfristplanung als verknüpfendes Element zwischen Strategieformulierung und operativer Umsetzung von Zielen

Zusammenfassung Die Mittelfristplanung ist in der betrieblichen Praxis weit verbreitet, wird in der Literatur dagegen wenig diskutiert. Dieser Beitrag stellt die Ergebnisse aus Fallstudien bei sechs marktführenden deutschen Konzernen vor und identifiziert typische Charakteristika der Mittelfristplanung. Die Mittelfristplanung ist in der Regel auf drei Jahre ausgelegt und stellt eine Schnittstelle zwischen der Strategieformulierung und der operativen Umsetzung von Ma?nahmen dar.

Mid term planning as a link between strategy formulation and goal achievement

Summary Mid-term planning is often used in German companies but not widely discussed in the literature. This paper shows the results of a case study project with six leading German companies and identifies typical characteristics of mid term planning. Mid term planning is typically covering a planning horizon of three years and can link the strategic goal setting process with the operative implementation of activities.

     

Worker replacement

Consider a labor market in which firms want to insure existing employees against income fluctuations and, simultaneously, want to recruit new employees to fill vacant jobs. Firms can commit to a wage policy, i.e. a policy that specifies the wage paid to their employees as a function of tenure, productivity and other observables. However, firms cannot commit to employ workers. In this environment, the optimal wage policy prescribes not only a rigid wage for senior workers, but also a downward rigid wage for new hires. The downward rigidity in the hiring wage magnifies the response of unemployment to negative shocks.     

Implementing Experiential Action Learning in International Management Education: The Global Business Strategic (GLOBUSTRAT) Consulting Program

This paper discusses the theoretical foundations and implementation challenges and outcomes of a unique “hands‐on” global consulting program that is integrated into an international EMBA program for mid‐career and senior American and European managers. It details the challenges for the integration of experiential action learning, double‐loop learning, service learning, and tacit learning into global management education and discusses the value of such integration for the EMBA‐participant's learning experience. The lessons learned from the implementation of the use of integrated global consulting based on an experiential action learning model on EMBA education are discussed. The andragogical model of education used should be a useful guide for designing and implementing experiential action learning based MBA/EMBA programs.
