Determinants of E-Business Use in U.S. Firms

The factors leading to variations in e-business use among U.S. firms are identified. Building on diffusion of innovation theory, an integrated model is developed that explains the relative influence of eight known determinants. Diversity and volume of e-business use are empirically investigated using a sample of 294 firms. The analysis demonstrates that (1) considering the diversity of e-business use, pressure from trading partners is the most important driver, (2) when e-business volume is investigated, government pressure emerges as the strongest factor, (3) government promotion may not have much effect on the diversity of e-business use by private companies, but does significantly influence the volume of e-business use by firms doing business with the government, and (4) the United States has a positive regulatory environment for supporting e-business. Taken together, these findings on the multidimensionality of e-business use show that diversity and volume are not only different measures of e-business use, but also have different determinants. The integrated model provides a more comprehensive explanation of e-business use and could serve as a foundation for future research on interorganizational systems.

INJURIES TO A SAMPLE OF SEATBELTED CHILDREN EVALUATED AND TREATED IN A HOSPITAL EMERGENCY ROOM

This study provides descriptions of the types of injuries sustained by a sample of children (0-14 years of age) who were using a vehicle seatbelt at the time of a motor vehicle accident and who were subsequently evaluated and treated in a hospital emergency room. Data were obtained from a hospital monitoring system established in nine emergency room facilities in a single county in California. The analysis indicates that in some cases injured seatbelted children were injured in circumstances in which the seatbelt could not have been protective, e.g., vehicle deformation into the child, flying glass, etc. The analysis of the remaining cases of seatbelted children suggests that there are significant variations in mechanisms of injury as well as injury patterns for different aged children. In many of the cases of injury observed in this sample, even though the child had been restrained in the adult seatbelt, the anatomic characteristics of the child prevented optional protection. The research provides further evidence for the necessity for utilizing specially designed restraints for children at least up to the age of 10 years.

Fetal death in motor vehicle accidents

This study represents a series of cases of fetal death secondary to maternal involvement in a motor vehicle accident. During the period 1982 to 1985, nine cases were reported to the county coroners office. In approximately 50% of the cases, other injuries to the victim, excluding injuries related to the pregnancy, were minor. Evidence of fetal distress was not always apparent at the time of initial evaluation. In all cases, placental abruption was documented. The injury mechanism was generally impact with the steering wheel. At the time of the accident, none of the patients were using seat belts. These cases demonstrate that minor maternal trauma without apparent maternal distress may result in fetal demise. The data indicate the need for prolonged continuous fetal monitoring for all pregnant women involved in motor vehicle accidents.

Strategic Orientation in the Globalization of Software Firms

In the search for profits, software firms are globalizing their development activities. Some firms achieve greater profits by becoming more efficient, whereas others do so by reaching new markets; some do both. This paper creates an a priori typology of strategies based on the extent to which firms are focused on operational improvement or market access, have a dual focus or are unfocused. We find that firms with these strategies differ in degree of internationalization, organization of offshoring and performance outcomes related to offshoring. Market-oriented firms receive a greater proportion of their total revenue from sales outside the U.S., showing a greater international orientation. They keep more of their offshore development in-house via captive operations. They also are most likely to report increased non-U.S. sales as a result of offshoring. On the other hand, operations-oriented firms have lower levels of international sales, are more likely to go offshore via outsourced software development, and achieve greater costs savings and labor force flexibility as a result of offshoring. Operations-oriented firms also face more obstacles in offshoring, perhaps because of their reliance on outsourcing. Dual focus firms generally achieve some of the best of both strategies, whereas unfocused firms achieve lower cost benefits.

Management Policy for Greater Computer Benefits: Friendly Software, Computer Literacy, or Formal Training

Using data from over 3,000 public employees in 46 U.S. cities in 1988, this article in vestigates three classes of factors commonly thought to affect computer use: training, friendliness of software, and user computer background. Computer use is analyzed as 11 specific tasks (such as programming, record searching) and is further broken down by organizational role of user, for example, manager and street-level employee. Some findings are that (1) the computer literacy or prior coursework of employees is more important to their computer use than how many years an employee has used computers; and (2) for most employees the user friendliness of programs is relevant, and weakly so, only for generic tasks such as searching a file or entering data. More generally, the data lead us to highlight training because it can be used to compensate for weaknesses in present software as well as in the computer literacy and experience of users. Keywords: computing benefits, friendly software, computer literacy, training.
