Telemetered heart rate and skin potential of a chronic schizophrenic patient especially during periods of hallucinations and periods of talking.

Took telemetric recordings of a male 23-yr-old chronic schizophrenic patient's heart rate and skin potential while on the ward. During periods of hallucinations, the skin potential increased significantly, while there were no changes in heart rate. Neither heart rate nor skin potential increased during periods of talking. When very angry, heart rate showed a substantial deceleration followed by a large increase. There was no change in skin potential during the period of anger.

A survey on resource allocation in high performance distributed computing systems

An efficient resource allocation is a fundamental requirement in high performance computing (HPC) systems. Many projects are dedicated to large-scale distributed computing systems that have designed and developed resource allocation mechanisms with a variety of architectures and services. In our study, through analysis, a comprehensive survey for describing resource allocation in various HPCs is reported. The aim of the work is to aggregate under a joint framework, the existing solutions for HPC to provide a thorough analysis and characteristics of the resource management and allocation strategies. Resource allocation mechanisms and strategies play a vital role towards the performance improvement of all the HPCs classifications. Therefore, a comprehensive discussion of widely used resource allocation strategies deployed in HPC environment is required, which is one of the motivations of this survey. Moreover, we have classified the HPC systems into three broad categories, namely: (a) cluster, (b) grid, and (c) cloud systems and define the characteristics of each class by extracting sets of common attributes. All of the aforementioned systems are cataloged into pure software and hybrid/hardware solutions. The system classification is used to identify approaches followed by the implementation of existing resource allocation strategies that are widely presented in the literature.     

Low-Pressure Flame Deposition of Nanostructured Oxide Films

The influence of electroless nickel plating on lead-based relaxor ferroelectric multilayer ceramic capacitors (MLCs) was studied by a comparison experiment. It was found that the influence is related to reactions in the electroless plating. It is proposed that adsorbed hydrogen atoms generated in electroless plating can diffuse into the ceramic bodies of MLCs and undergo some reduction reaction with them, resulting in the failure of electroless nickel plating. The implications for the negative influence of electroplating on MLCs and for the degradation in MLCs are also included, in which much attention is paid to the reduction reaction of hydrogen atoms generated by electrolysis of water.     

Differential K theory and racial hierarchies.

Discusses J. P. Rushton's (see record 1986-17266-001) differential K theory (derived from the r/K model of evolutionary selection), which purportedly explains racial differences in sexual practices and anatomy, fertility, IQ, and criminality. The r/K model is frequently misinterpreted and overgeneralized. The predictions that Rushton derives from the r/K model are arbitrary, and these predictions are supported by selective citation and misrepresentation of the research literature and by the use of unreliable sources. Changes in human life-history traits are so rapid that there is no need to posit genetic selection to explain intergroup variation.

Obituary: David Bakan (1921-2004).

Presents an obituary for David Bakan, one of the most creative and provocative thinkers in psychology. David's best known paper on psychological method may be his critique of the test of significance in psychological research. David was one of the earliest psychologists to promote the use of Bayesian statistics as an alternative to conventional statistical approaches, first publishing on the topic in 1953. He was one of the founders of the American Psychological Association's Division 26, the History of Psychology, and served as the president of the division in 1970-71. He died in Toronto on October 18, 2004. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Measurement of Power Frequency Fluctuations Using the FFT

A new method for detecting fluctuations in the fundamental frequency component of a power system, by relating it to a leakage coefficient in the FFT, is presented. The phenomenon of leakage in the FFT is used advantageously to increase spectral resolution. The leakage coefficient is a quantitative measure of the deviation from the fundamental frequency component with respect to the sampling frequency. Theoretical aspects are considered along with a method for on-line implementation.     

Effects of communication, information overlap, and behavioral consistency on consensus in social perception.

Three experiments (N?=?69, 162, and 201, respectively) were conducted to test the mathematically derived predictions of the Weighted Average Model (D. A. Kenny, 1991) of consensus in interpersonal perception. Study 1 estimated the effect of perceiver communication, Study 2 estimated the effects of communication and stimulus overlap, and Study 3 estimated the effects of communication, overlap, and target consistency on consensus. The strongest consensus was found when perceivers communicated about highly overlapping information about targets who were cross-situationally consistent. Conversely, the lowest level of consensus was observed when perceivers did not communicate and had nonoverlapping information about targets who were cross-situationally inconsistent. Both stimulus variables (overlap and consistency) and an interpersonal variable (communication) affected consensus as predicted by the Weighted Average Model.

Allelopathic potential of sorghum (Sorghum bicolor)

The major inhibitory components obtained after fractionation of an aqueous extract of field-grown sorghum (Sorghumbicolorcv. Bird-a-boo) herbage were quantified in terms of biological potency by indexing three aspects of cumulative cress (Lepidium sativum cv. Curlycress) seed germination. The inhibitory potential expressed in the crude aqueous extract reflected a complex interaction of numerous individual components of diverse chemical compositions and potencies. Some of these inhibitory components included chemical classes not previously associated with herbage phytotoxicity.     

The observers and the observed: The effects of doing ratings on staff-patient contact patterns.

On a research ward where nursing personnel have both research and clinical responsibilities, the effect of staff's rating of patients' behavior on frequency of contacts was assessed. Percentages of staff's contacts with patients and with other staff were compared on days when the staff was doing the ratings with days when it was not. There were no differences in the percentage of interactions with patients on rating and nonrating days. There were more interactions with staff on rating days. This finding suggests that although doing rating did not interfere with patient-staff relations, the increase in staff-staff contacts might be due to rating staff obtaining more information upon which to base their ratings by talking to other staff members.
