Small is beautiful: Implications of reliability and statistical power for testing the efficacy of HR interventions

The development of optimal human resource practices is often contingent on the accurate statistical testing of potential interventions. Testing the efficacy of HR interventions can be enhanced by taking additional measures to improve statistical power, but the traditional means of increasing power through sample size are often beyond the cost and ability of HR professionals to pursue. This article, therefore, focuses on measurement procedures as an alternative way to increase statistical power for detecting HR intervention effects. Selection of reliable and appropriate measures and subsequent instrumentation are examined as efficacious and cost‐beneficial techniques that can be employed during the planning and designing stage of a study for augmenting statistical power to optimize business decision making. © 2012 Wiley Periodicals, Inc.     

Advertising,concentration and profitability in Greek food manufacturing industries

The conventional framework for cross-sectional studies of industrial organisation focuses on the hypothesised relations among structure, conduct and performance (SCP). This paper investigates these relationships for the food and beverage manufacturing industries in a European country, i.e., Greece. 3SLS method is used to estimate the parameters of the profitability, concentration and advertising model for a sample of 38 four-digit industries in 1994. The main results, which are in line with the relevant empirical work, show that profitability is determined by advertising, which, in turn, is affected by both profitability and concentration, while the latter is determined by economies of scale.

Site selection to test an integrated approach to agricultural research for development: combining expert knowledge and participatory Geographic Information System methods

The sub-Saharan Africa challenge programme is designed to address the problems of failures of agricultural markets, inappropriate policies and natural resource degradation, that contribute to the continuing deterioration of livelihoods and food security in the region. It is seeking to do this by redefining the roles of scientists and farmers through collaborative learning processes, addressing questions about the level, timing, type and formof participation, as well as themost effective approaches andmethods to foster them. The research domains of the programme deal with sustainable intensification of smallholder agriculture, the sustainable management of natural resources, the development of efficient markets, and the promotion of enabling policies. One question that was addressed in designing the initiative was deciding where to work so as to maximize the chances of successful testing of this new approach, so that it would lead to significant reductions of rural poverty. A participatory process was put in place to design a framework to accomplish this site selection, and then to apply it in west, east and southern Africa. A mixture of spatial data analysis and expert knowledge on spatial and non-spatial factors was used, and one primary site in each region was identified to form the basis for the next phase of the challenge programme. Several lessons were learnt from the process, including the importance of adapting themethods to actual conditions, the increased utility of targetting when the quantitative and the qualitative are freely combined, and the continued need for baseline spatial and non-spatial data to improve the targeting of research in the future that is designed to alleviate poverty in sub-Saharan Africa.     

Erfolgreiche Sanierung in der Insolvenz aus Sicht des Schuldnerunternehmens

Zusammenfassung Der Beitrag stellt die M?glichkeiten eines geplanten und gesteuerten Einsatzes des Insolvenzverfahrens zur Sanierung Not leidender Unternehmen dar. Aufbauend auf den Erkenntnissen der Krisentheorie sowie einer ?konomischen Analyse des Insolvenzrechts eignen sich aus Sicht eines schuldnerischen Unternehmens vor allem das Insolvenzplanverfahren auf Basis eines Antrags wegen drohender Zahlungsunf?higkeit in Verbindung mit einem Antrag auf Eigenverwaltung zur Sanierung in der Insolvenz. Der Erfolg der gerichtlichen Sanierung h?ngt dabei ma?geblich von einem effizienten Vorgehen unter Beachtung des aus Sicht der Anteilseigner optimalen Insolvenzzeitpunkts, der Bewertung der Insolvenzeignung des zu sanierenden Unternehmens und der Entscheidung über die Verwertungsart ab.

Summary This paper addresses the options of systematically managed insolvency proceedings to reorganise nonperforming firms. Crisis theory and an economic analysis of insolvency law suggest an “Insolvenzplanverfahren” based on a motion because of imminent insolvency in conjunction with requesting a debtor in possession solution is the best option for an indebted company. The success of a juristictional reorganisation depends on the optimal time to file for insolvency, a preselection of companies based on the appropriateness for a juristictional reorganisation, and the decision on asset utilisation.
