Additions to the Hyperaspis Chevrolat (Coleoptera: Coccinellidae) fauna of South American, descriptions of nine new species, and recognition of Hyperaspis pectoralis Crotch as a valid species

Nine new species of Hyperaspis from various South American localities are described, illustrated, and compared with previously described taxa. New taxa are: Hyperaspis luciae, H. corcovado, H. divaricata, H. humboldti, H. mimica, H. praecipua, H. unimaculosa, H. drechseli, and H. esmeraldas. Hyperaspis pectoralis Crotch is recognized as a valid species of Hyperaspis and integrated into the existing classification

Descriptions of the male of Heterodiomus marchali Brèthes and a new species of Chilean Heterodiomus Brèthes (Coleoptera: Coccinellidae: Scymninae: Diomini)

Additions to the classification of South American Diomini are provided. Male genitalia of Heterodiomus marchali Brèthes are described and Diomus brethesi is newly described

Why It Is Difficult to Apply Revenue Management Techniques to the Car Rental Business and What Can Be Done About It

Revenue management systems are used by airlines, hotels, and cruise lines to manipulate prices and availability of inventory in real-time, in order to increase profit. We discuss the reasons that the revenue management problem is more complex when applied to the car rental business. We then show how to simplify the model formulation and provide the human-computer interaction, organization, and procedures to make the problem tractable for the car rental business

Management Information Sources and Corporate Intelligence Systems

In this book the word “intelligence” is used in several different contexts. Intelligence can refer to the process of gathering data; it can refer to the data itself; and it can refer to the application of knowledge to product useful information from the data. We will see in this chapter how the computer can be used in business to further all three aspects of intelligence: capturing the data, storing the data in an accessible form, and adding value to the data by transforming it into useful information for decision making. This chapter is organized according to these three areas of computer support for business intelligence: 1. Transaction processing and intelligence capture 2. Data-base management and intelligence storage and retrieval 3. Decision support systems and intelligence processing We provide an overview of the concepts in transaction processing, data-base management, and decision support systems. References are listed in each of these areas for further details. Our purpose is to provide the perspective for the executive to detenmne the use of these concepts for his or her company and to understand the choices open to him or her in today’s technology

Using Microsoft Excel to Teach Simulation Concepts to Business Students

The application of computers to solving business problems, the area of study known as decision support systems, is an important component in the education of business students today. One major type of decision support system is computer simulation, which is the technique most often used to solve queuing problems in the industry. This paper describes how to teach the concepts of computer simulation, explain the key components of simulation software, and provide hands-on experience to solve these problems by using Microsoft Excel

Higher Level Modeling in RESQME

RC 13554 (#60544) The RESearch Queueing Package Modeling Environment (RESQME) is a graphical workstation environment for iteratively constructing, running and analyzing models of resource contention systems. It is built on top of the RESearch Queueing Package (RESQ) which provides the functionality to evaluate extended queueing networks. In this paper we describe the high-level building component design for RESQME. The modeler is provided with tools to create his own icons and to associate them with submodels. He then uses ilicsc building blocks to construct his model. This capability extends the funtlaiiicnlal building blocks of RESQ and allows the user to create models with objccls directly related to his application domain

Application Interface Development Environment

RC 11160 (#50246) The user of interactive systems must learn a different interface for each system he uses. Furthermore the designer of such systems has limited guidelines to create good user interfaces. We describe an application interface development environment, AIDE, in which one can create and select multiple interfaces easily for a given application, and conversely one can create multiple applications with a given interface. This benefits the end-user by providing the possibility of familiar, even identical, interfaces among wide ranges of products, and this helps the designer by supporting Human Factors testing of interfaces. We formulate a model of interactive systems in which the application and interface are decoupled and the components of the interface can be changed. We also provide tools for these components and a methodology to create and sélect interfaces

A Comparison of Intrauterine and Cervical Artificial Insemination Catheters on Farrowing Rate and Litter Size in Artificially Mated Sows

The objectives of this study were to determine the effects of artificial insemination (AI) catheter type on litter size and farrowing rate. No performance difference was found between sows artificially inseminated using intrauterine or intracervical methods. Since intrauterine catheters typically are more expensive, there is an economic advantage for the more commonly used intracervical method of artificial insemination in the present study
