A Comparative Study of Institutionalizing Public Plant Breeding

Public–private partnerships are merely defined as an institutionalized cooperation between the public administration and private companies, but may take very different settings. This paper uses the case of partnerships in the plant breeding sector to study the institutional evolution of such linkages. It is shown how corporatist exclusivity can enter such partnerships, as their setting can have different purposes and be used to transfer subsidies from the public to companies or professional associations through low prices for resources transferred to the sector. The inefficiencies connected with such rents and possible alternatives are outlined and conclusions are drawn for the institutional theory of organizations.     

A social indicator based on time allocation

The authors have developed a social indicator, called Lambda, that has as its base the manner in which individuals allocate their time among various life activities. This indicator does not suffer from the usual demand characteristics and experimenter bias associated with most subjective social indicators, i.e., those based on question-naires. It is not a single rate indicator in the sense of suicide rate. Lambda is a weighted sum social indicator with both subjective and objective aspects. The weights are decided by the population under consideration and not by the investigators or some other outside agents. The elements to be summed are the frequency functions for the discrepancies that arise when individuals state the amount of time they would like to spend in an activitiy versus the amount of time they actually spend at the activity. There are frequency functions for each activity. The properties of this indicator are discussed in detail. A pilot study comparing Lambda to another social indicator and some demographic variables was conducted with 1012 undergraduate students. The results of the pilot study show a high correlation between Lambda and the other social indicator. The results are presented. Lambda is currently being used by the Gallup organization.     

Industrial relations problems—OR's contribution

This paper considers the contribution which OR (Operational Research) can make to solving some of the problems in the industrial relations field. It first discusses the characteristics of industrial relations problems, categorising them according to the degree of conflict involved. The kinds of contribution OR can make are then discussed, first in a general way and then for each category in turn. The paper draws particular attention to the need for OR work in much of the industrial relations field to take account of the existence of conflict and of the game-like nature of the negotiating process. Some of the problems this presents to the OR worker are mentioned. Directions for future developments in the field are proposed. Finally there is a brief discussion about whether the issues raised in the paper are relevant to OR's contribution in fields other than industrial relations.     

Effects of a Differential Observing Response on Intraverbal Performance of Preschool Children: A Preliminary Investigation

Axe (2008) speculated that some instances of intraverbal responding might be associated with limited or delayed acquisition because they require discrimination of multiple components of verbal stimuli. Past studies suggest that acquisition of responses under control of complex, multicomponent antecedent stimuli (e.g., conditional or compound stimulus control) can be facilitated with the introduction of a differential observing response (DOR; Dube & McIlvane, 1999; Gutowski, Geren, Stromer, & Mackay, 1995). The purpose of the current study was to evaluate the effects of a DOR (i.e., repeating the question) on intraverbal responding with six neurotypical preschool children. Findings included that (a) accuracy of intraverbal performance increased when the experimenter prompted a DOR; (b) 1 of 6 participants overtly emitted the DOR for a second relation in the absence of prompts, which was correlated with increased accuracy; and (c) following mastery, response accuracy was variable for 3 participants. Based on these findings, prompted DORs may offer an effective, if temporary, aid to intraverbal instruction for neurotypical preschool children.     

IMPLICATIONS OF A MODAL-DELAYED DISTRIBUTED LAG RESPONSE TO ADVERTISING EXPENDITURE*

This paper reviews a generalized optimal theoretic advertising model with the flexibility to account for a modal-delayed (inverted V), distributed lag response to advertising expenditure. Three econometric techniques are used in a general test of this model. Conclusions show that models constrained to a simple exponential lag overspecify the optimal level of advertising.
