Pre-visual detection of stress in pine forests
Pre-visual, or early, detection of forest stress with particular reference to detection of attacks by pine bark beetles is discussed. Preliminary efforts to obtain early detection of attacks by pine bark beetles, using MSS data from the ERIM M-7 scanner, were not sufficiently successful to demonstrate an operational capability, but indicate that joint processing of the 0.71 to 0.73, 2.00 to 2.60, and 9.3 to 11.7 micrometer bands holds some promise. Ratio processing of transformed data from the 0.45 to 0.52, 1.55 to 2.60, and 4.5 to 5.5 or 9.3 to 11.7 micrometer regions appears even more promising
Forest Species Identification with High Spectral Resolution Data
Data collected over the Sleeping Bear Sand Dunes Test Site and the Saginaw Forest Test Site (Michigan) with the JPL Airborne Imaging Spectrometer and the Collins' Airborne Spectroradiometer are being used for forest species identification. The linear discriminant function has provided higher identification accuracies than have principal components analyses. Highest identification accuracies are obtained in the 450 to 520 nm spectral region. Spectral bands near 1,300, 1,685 and 2,220 nm appear to be important, also

Remote sensing of changes in morphology and physiology of trees under stress
Measurements on foliage samples collected from several drought and salt treated plants revealed that leaf thickness decreased with increasing severity of the drought treatment and increased with increasing severity of treatment with NaCl, but remained essentially unaffected by treatment with CaCl2. Airborne data collected by multispectral scanner indicated that false color images provide selective enhancement of a diseased area. Comparison of simulated and actual aerial color and color IR photography revealed that the color renditions of the MSS simulations agreed closely with those of the actual photography

THE IMPACT OF INFORMATION TECHNOLOGY ON ORGANIZATIONAL FLEXIBILITY
This paper argues that information technology can have a significant impact
on organizational flexibility. Information technology (IT) contributes to flexibility
by 1) changing the nature of organization boundaries and the time at which work
takes place and 2) altering the nature and pace of work. IT also has important
second and third order impacts on organizations and industries. The paper presents
examples to illustrate the impact of information technology on two industries and
three companies. The paper concludes that management should consider the use of
information technology to increase flexibility and should predict the higher order
impact of their actions on the organization and their industry.Information Systems Working Papers Serie

Nutritional Consequences of Food Insecurity in a Rural New York State County
This study of women with children in a rural county of upstate New York examined the relationships of food insecurity and income with two nutritional consequences (adiposity and fruit and vegetables consumption), and assessed whether disordered eating patterns is a mediator for the effects of food insecurity and income on these nutritional consequences. Each of 193 respondents was interviewed twice in her home. Data were collected on household food stores, socioeconomic and demographic characteristics, methods of obtaining food, food program participation, household expenditures, food intake, the Radimer/Cornell hunger and food insecurity items, height, weight, frequency of fruit and vegetable consumption, and disordered eating patterns. Regression analysis was used to analyze the relationships of body mass index and an obesity classification with height, income, education, single parenthood, employment, food insecurity, disordered eating, and frequency of fruit and vegetable consumption. Regression analysis was also used to examine the relationships of disordered eating and frequency of fruit and vegetable consumption with the other variables. Lower income and unemployment were related to higher adiposity. The effects of income on adiposity were not mediated through disordered eating patterns or through fruit and vegetable consumption. Food insecurity was related to adiposity, and part of this effect of food insecurity was mediated through disordered eating. This mediating effect of disordered eating partially explained why those experiencing the least severe food insecurity were more likely to be overweight than those who were food secure, but those experiencing the most severe food insecurity were less likely to be overweight than those who were food secure. Food insecurity was related to lower fruit and vegetable consumption, but this did not translate into effects on adiposity.
The Impact of Office Automation on the Organization: Some Implications for Research and Practice
Computer technology has recently been applied to
the automation of office tasks and procedures. Much of
the technology is aimed not at improving the efficiency
of current office procedures, but at altering the nature of
office work altogether. The development of automated
office systems raises a number of issues for the organization.
How will this technology be received by organization
members? How will it affect the definition of
traditional office work? What will be its impact on
individuals, work groups, and the structure of the organization?
This paper presents a descriptive model and
propositions concerning the potential impacts of office
automation on the organization and it stresses the need,
when implementing automated office systems, to take a
broad perspective of their potential positive and negative
effects on the organization. The need for further research
examining the potential effects of office automation is
emphasized.Information Systems Working Papers Serie
