Employment interviewer reactions to former mental patients.

A job applicant (male undergraduate) obtained an interview at 32 manufacturing concerns and in 16 of these places he indicated he had been traveling the preceding 9 months while in the others he said he had been in a mental hospital for the same period of time. Each interview was surreptitiously sound recorded. The recordings were rated for friendliness of interviewer behavior and probability that a job might be available there. A history of mental illness led to a trend for fewer jobs to be offered (4 in the traveling condition and 2 in the mental illness condition), less friendly behavior, and lowered estimated probability of finding a job.

Mental illness and the impact of believing others know about it.

Reports 2 studies measuring the impact upon 30 male inpatients and 29 male outpatients of believing others have become aware of their psychiatric history. Ss thought the interest was in determining if another person would behave the same toward mental patients and controls. 1/2 the Ss were told the other person knew they were patients and the remainder that he believed them to be nonpatients. Believing others were aware of their status caused Ss to feel less appreciated, to find a task more difficult, and to perform more poorly, and they were perceived as more tense, anxious, and poorly adjusted by an O.

A novel approach for precise simulation of the EMG signal detected by surface electrodes

We propose a new electromyogram generation and detection model. The volume conductor is described as a nonhomogeneous (layered) and anisotropic medium constituted by muscle, fat and skin tissues. The surface potential detected in space domain is obtained from the application of a two-dimensional spatial filter to the input current density source. The effects of electrode configuration, electrode size and inclination of the fibers with respect to the detection system are included in the transfer function of the filter. Computation of the signal in space domain is performed by applying the Radon transform; this permits to draw considerations about spectral dips and clear misunderstandings in previous theoretical derivations. The effects of generation and extinction of the action potentials at the fiber end plate and at the tendons are included by modeling the source current, without any approximation of its shape, as a function of space and time and by using again the Radon transform. The approach, based on the separation of the temporal and spatial properties of the muscle fiber action potential and of the volume conductor, includes the capacitive tissue properties.     

Disentangling time in a near-field approach to scanning probe microscopy

Microwave microscopy has recently attracted intensive effort, owing to its capability to provide quantitative information about the local composition and the electromagnetic response of a sample. Nonetheless, the interpretation of microwave images remains a challenge as the electromagnetic waves interact with the sample and the surrounding in a multitude of ways following different paths: microwave images are a convolution of all contributions. In this work we show that examining the time evolution of the electromagnetic waves allows us to disentangle each contribution, providing images with striking quality and unexplored scenarios for near-field microscopy.     

Study of green Sicilian table olive fermentations through microbiological,chemical and sensory analyses

The production of five different green table olive cultivars was studied by a combined strategy consisting of chemical, microbiological and sensory analyses. Cultivable microflora of samples collected during processing was monitored by plate counts on seven synthetic culture media. In all samples Enterobacteriaceae, Pseudomonaceae, staphylococci, lactic acid bacteria and spore-forming bacteria were undetectable. Yeasts and moulds were countable from the day 42 (2 log CFU/ml) till the end of fermentation (6 log CFU/ml). The use of three different approaches for microorganism detection, including a culture-independent methodology, revealed the presence of barely three yeast species during the entire fermentation period: Candida parapsilosis, Pichia guilliermondii and Pichia kluyveri. Biochemical features of technological interest were evaluated for 94 strains in order to investigate their potential role in fermentation of green Sicilian table olives.     

Changes in endogenous benzodiazepine-like compound levels during the course of fulminant hepatic failure: potential effects of decreased renal function

The pathogenetic agents which cause encephalopathy due to fulminant hepatic failure are still under debate. Ammonia and benzodiazepine-like compounds are two of the most important agents considered, so far. Herein, we report the levels of benzodiazepine-like compounds in serum and in urine and of venous ammonia measured during the course of the disease (30 days). The patient rapidly developed stage IV encephalopathy with high levels of ammonia and with only a slight increase of benzodiazepine-like compounds. At that moment, the levels of these compounds were similar to those recorded in the blood when the patient regained full consciousness 28 days later. During the course of the disease, there was a 10-fold increase of benzodiazepine-like compounds in serum which was recorded in parallel with an impaired excretion due to oliguria. This observation seems to indicate that encephalopathy may develop in the absence of significantly increased levels of these compounds and that their episodic increase during fulminant hepatic failure may be an epiphenomenon linked with several factors such as impaired renal function.
