Organizational arrangements for MIS units

Decisions on organizational arrangements for MIS units comprise location in the organization, rank of responsible executive, organization of MIS implementators, degree of centralization, the user interface, the study group, the steering committee, the data base administrator, the corporate computer staff, and external assistance. Based on a wide-ranging survey of papers in the field of MIS, the authors have formulated guidelines which derive from the impact of organizational decisions on the success or failure or MIS and MIS projects.     

The deconvolution of Doppler-broadened positron annihilation measurements using fast Fourier transforms and power spectral analysis

A deconvolution procedure which corrects Doppler-broadened positron annihilation spectra for instrument resolution is described. The method employs fast Fourier transforms, is model independent, and does not require iteration. The mathematical difficulties associated with the incorrectly posed first order Fredholm integral equation are overcome by using power spectral analysis to select a limited number of low frequency Fourier coefficients. The FFT/power spectrum method is then demonstrated for an irradiated high purity single crystal sapphire sample.     

Stressful life events' effects on rheumatoid arthritis disease activity.

A 53-year-old female rheumatoid arthritis (RA) patient endured 2 unexpected family deaths during a 12-week study investigating the prospective relationships between stressful small life events, negative affect, and disease activity. Her disease went into temporary remission the same week as the deaths. She was identified as a case study participant, and weekly data collection was extended to 1 year. Clinical exams verified a large decrease in disease status immediately after the major losses. In addition to major events, negative affect and small events were found to serve as independent arthritis symptom predictors within this patient. Major events were associated with decreased symptoms. Negative affect and small events related to symptom increased. Subsequent between-subjects analyses conducted on 25 participants from the parent project probed for generalizability. The substantive findings from the case study were supported: Major life events and small life events functioned as opposing predictors of RA disease states.

Arylsulfonate esters of fatty alcohols as hypocholesterolemic agents. I: Oleyl and linoleyl p-toluenesulfonates

Cholesterol levels of both plasma and liver of cholesterol-fed rats are lowered by feeding linoleyl and oleyl esters of p-toluenesulfonic acid. A structural specificity exists, since the effect is not observed with similar amounts of sodium p-toluenesulfonate nor with linoleyl methanesulfonate. Effective levels of these arylsulfonates do not alter liver to body weight ratios and maturation, nor reduce plasma cholesterol in normocholesterolemic rats.

Six PL/I compilers

This paper describes an experimental evaluation of the execution speed of object programs produced by six PL/I compilers. A set of 139 representative PL/I statements were compiled and executed under the PL/I Optimizing, PL/I(F), PL/C, PL/I Checkout, SP/k and PLUTO compilers. An analysis is made of the relative speed of the object code produced by each compiler and also of the relative execution speed of each statement.     

Factors affecting the moisture barrier of vinylidene chloride-vinyl chloride copolymer films

Copolymers of vinylidene chloride, SARAN* resins, can be fabricated into films which have excellent barrier to mass transport. They are useful for making packages which must keep oxygen out or prevent moisture from entering or leaving. The oxygen barrier properties of SARAN films have been recently published (8). The purpose of this paper is to describe the moisture barrier properties of SARAN films as functions of temperature, humidity, and film composition. This information will aid packaging engineers design better barrier packaging.     

Discriminative utility of a brief cognitive status assessment with alcoholics and the impact of cognitive status on acquisition of treatment-relevant information.

Assessed the discriminative utility of a brief assessment procedure for quantifying cognitive status in alcoholics and the impact of existing cognitive status on acquisition of information presented during treatment. 112 male patients (aged 20–77 yrs), consecutively admitted to an inpatient alcohol treatment program, were assessed at admission and discharge. The 30-min assessment protocol included the Rey Auditory Verbal Learning Task (M. D. Lezak, 1983), portions of the Wechsler Memory Scale, and a brief structured interview that assessed treatment-relevant knowledge. These measures were able to differentiate performance levels related to age and drinking history. Recent drinking behavior and cognitive function may only moderately influence acquisition of treatment program content. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Referral patterns in ethnic-specific and mainstream programs for ethnic minorities and Whites.

The present study examined the referral patterns of 1,095 African, 2,168 Asian, 1,385 Hispanic, and 2,273 White Americans (18 years of age and older) in a public mental health system to determine whether group differences in help-seeking and referral patterns were related to participation in ethnic-specific versus mainstream programs. Results indicated that (a) ethnic minorities in both mainstream and ethnic-specific programs were more likely than Whites to have been referred by natural help-giving and lay referral sources (e.g., family or friends, health services, and social services) and (b) ethnic minorities in ethnic-specific programs were more likely than ethnic minorities in mainstream programs to have been referred by natural help-giving and lay referral sources if they were Asian and Hispanic Americans and self-referred if they were African Americans.
