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 modification of nylon 6 by a phenol-formaldehyde resin

Modification of nylon 6 by blending with a small amount of a novolac resin has been investigated. Unexpected increased of T_g and tensile modulus and reduction in moisture absorption have been found at levels of novolac incorporation of 1–3 wt %. The small amount of novolac resin also has an effect on the crystallization and nylon 6 crystal structure (α vs. γ form). © 1993 John Wiley & Sons, Inc.     

The federal health scientist-administrator: An opportunity for role integration.

The federal health scientist-administrator is centrally involved in the national health program and serves in the interface between science and public policy. In this middleman role there is a role conflict which derives from the dichotomy between his values as a scientist and as an administrator. He is viewed as an expert in the process of federal grantsmanship as well as in the research area for which he has responsibility. It is suggested that he must be willing to accept this role conflict as an attribute of science administration today and work toward a process of integrating the 2 roles. Psychologists and other behavioral scientists should participate in such an effort at integration. (15 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Defense" against traumatic concepts.

Shows that traumatic responses attached to 1 instance of a concept will impair the identification of the concept even when the traumatized concept is not part of the concept identification task. Such traumatic priming proved detrimental compared with either neutral priming or no priming. Neutral priming proved to facilitate concept identification.

The assassination of Yitzhak Rabin: Resonance of a national tragedy in psychotherapy.

Examined the reactions of 31 Israeli patients (aged 15–60 yrs) in psychotherapy to the assassination of Prime Minister Yitzhak Rabin using a single-site study. Data were collected during the 1st psychotherapy session following the fatal shooting of the Prime Minister. The 31 vignettes were investigated by 8 clinicians. The patients' reactions were subjected to a qualitative data analysis that yielded high intercoder agreement with regard to 20 codes clustered in 4 content categories: (1) object of reference, (2) perceived threat, (3) personal association, and (4) affect. No apparent relationships between DSM diagnoses and any response patterns were identified, indicating that the Ss might have responded with grief reactions that transcended diagnostic nosologies. Findings indicate, however, that Ss with a history of paternal child abuse were significantly more likely to respond in a unique way. These Ss often identified with members of the surviving family or with the assassin rather than with the slain leader; explored anxieties about the looming dangers emanating from the Israeli extreme right; and displayed feelings of revenge, disgust, or satisfaction with this figurative patricide. These findings are discussed from a psychodynamic perspective. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Catalyst Sintering and Reactor Design

The subject of sintering (sometimes termed coarsening) has received considerable attention since the late 1960s, and a review [1] appeared in this journal in 1975. Significant progress has been made since then, in particular, with regard to the mechanisms and kinetics of sintering and measurement techniques. With these advances it is now possible to utilize the understanding gained for the design of reactors undergoing catalyst sintering. In fact, a few attempts have already been made.     

Quantifying motion in video recordings of neonatal seizures by robust motion trackers based on block motion models

This paper introduces a methodology for the development of robust motion trackers for video based on block motion models. According to this methodology, the motion of a site between two successive frames is estimated by minimizing an error function defined in terms of the intensities at these frames. The proposed methodology is used to develop robust motion trackers that rely on fractional block motion models. The motion trackers developed in this paper are utilized to extract motor activity signals from video recordings of neonatal seizures. The experimental results reveal that the proposed motion trackers are more accurate and reliable than existing motion tracking methods relying on pure translation and affine block motion models.     

Improving the accuracy and reliability of motion tracking methods used for extracting temporal motor activity signals from video recordings of neonatal seizures

This paper presents an approach for improving the accuracy and reliability of motion tracking methods developed for video based on block motion models. This approach estimates the displacement of a block of pixels between two successive frames by minimizing an error function defined in terms of the pixel intensities at these frames. The minimization problem is made analytically tractable by approximating the error function using a second-order Taylor expansion. The improved reliability of the proposed method is illustrated by its application in the extraction of temporal motor activity signals from video recordings of neonatal seizures.
