Budget Planner is a whole-farm or enterprise budgeting software program that is simple to use for farmers, extension agents, and other budgeters who are sometimes inexperienced, but that also provides the detail necessary to be accurate. Program defaults eliminate repetitive questions that change little from budget to budget. Defaults can be temporarily overridden, or they can be permanently changed with a detailed modify program. The program leads a user through a sequence similar to that a producer might utilize. Input forms were created to enlarge the user clientele and eventually increase computer use by farmers and extension agents.

This paper presents a conceptual framework, known as systems development, for designing, selecting, and evaluating information systems. Techniques are developed that aid farm managers in choosing an accounting system. Six farmers took part in case studies testing the selection techniques. The participating farmers exhibited great diversity in the preferred design of their accounting systems and the manner in which they desired reports to be presented. This diversity suggests that system selection is an important aspect of implementing an accounting system.

Poor management of the southeastern vegetable marketing cooperatives has been linked to poor record keeping practices. The VEGMARC II© Record Keeping Program is part of a comprehensive multi-agency effort to provide solutions to the problems of south-eastern vegetable marketing cooperatives. This computer program has been refined and expanded during four years of field testing. VEGMARC II© features include pool price calculations, deduction of packing fees, calculation of grower net returns, and the printing of reports, checks, and mailing labels. Eighty percent of cooperatives responding to user surveys indicated the program was meeting the needs of their cooperative.

This paper describes four agribusiness simulators which can be processed on a microcomputer for use in undergraduate and extension teaching. The simulators model the environment in which supermarket chains, farm supply centers, and cooperative and proprietary grain elevators compete for business. Instruction manuals, user's manuals, and a diskette are distributed for each simulator. Each diskette contains programs to enter and edit team decisions, to process decisions and print reports, and to create graphs of team performance. The simulators can be used to teach financial management concepts and techniques, as well as economic principles.

The Net Present Value Sire Summary Professional Package (NPVSS) is a microcomputer program designed for technical personnel to help dairy producers better manage investments in genetic improvement. NPVSS is written in C language, utilizes the MS-DOS operating system, and requires 256K of RAM. It is menu driven and includes parameter screens to define herd management characteristics of individual producers. Profit rankings of bulls can be generated to evaluate alternative: a) objective functions (selection policies for genetic merit in milk income and type scores), b) herd management performance factors (conception rate, calving interval, age at first calving), and c) economic factors (milk price, semen price, discount rate, planning horizon).

This paper describes computer-assisted instruction for financial management which can be used to supplement an undergraduate course or to update training of persons in agribusiness. It is used to review principles of financial management, to illustrate analytical techniques, and to provide practice in the use of financial concepts and techniques. The material covered is similar to that found in traditional textbooks. Student evaluations of the software were fairly positive, but teaching effectiveness needs to be measured.

Les propriétés psychostimulantes de trois doses (25, 50 et 75 mg) d’un agoniste partiel des benzodiazépines, la pipequaline (PK-8165, figure 1), ont été comparées à celles mesuràes sous placebo chez 18 volontaires sains.

Les mesures réalisées avant la prise, 2, 5 et 7 heures après la prise, comprenaient une batterie d’échelles visuelles analogiques (tableau 1) ainsi que 4 tests informatisés (discrimination visuelle, “visual scanning”, temps de réaction en champ central et latéral, “digit/digit”).

Les données analysées par analyse de variance à mesures répétées montrent que la pipequaline ne possède pas, aux doses utilisées, d’effet sédatif et que, en général, la dose la plus faible induit une diminution des temps de réaction et une augmentation de la capacité d’attention (figures 4 à 6). Quant aux lignes d’auto-évaluation, les sujets se sentent plus éveillés, plus calmes, l’esprit plus clair, plus adroits, plus énergiques, plus attentifs, plus intéressés et plus réservés, en général sous 25 mg (figures 2 et 3).

Ces résultats confirment ceux déjà observés dans une étude précédente et montrent, de surcroît, la sensibilité et le pouvoir de discrimination des méthodes utilisées.

Cette étude suggère que de faibles doses de pipequaline méritent d’être testées en clinique particulièrement dans une symptomatologie asthénique et, sous toute réserve, dans une symptomatologie anxieuse.
