Reaction to the Special Section on supervision research: Comment on Ellis et al. (1996), Ladany et al. (1996), Neufeldt et al. (1996), and Worthen and McNeill (1996).

Both the post-positivistic (M. V. Ellis, N. Ladany, M. Krengel, and D. Schult; N. Ladany, C. E. Hill, M. M. Corbett, and E. A. Nutt; see PA, Vol 83:21766 and 24267, respectively) and interpretive (S. A. Neufeldt, M. P. Karno, and M. L. Nelson; V. Worthen and B. W. McNeill; see PA, Vol 83:24269 and 24281, respectively) studies in this special section on supervision research are reviewed from the perspective of rigor and relevancy to the critical questions facing educators and practitioners of supervision. The value of different empirical methods to uncover the meaning and structure of supervision is discussed in light of these researchers' contribution to building a theory of practice. Empirical findings of both methods are needed to guide the systematic teaching of psychotherapy in supervision and the teaching of supervision itself.

Molecular subtyping of Treponema pallidum subspecies pallidum

PURPOSE: Psychosocial distress and patient attitude towards psychosocial support as well as the correlations with clinical and sociodemographic characteristics should be assessed. METHODS: The stress due to cancer was measured in a consecutive sample of tumor patients at the start of radiotherapy (n = 117) by use of the Hornheide Questionnaire. In addition, the interest of these patients in professional psychosocial support was assessed with the help of the Questionnaire for Psychosocial Support. RESULTS: Patients in the course of radiotherapy and patients with a poor prognosis and advanced disease were more strongly distressed. 32.7% of patients wished professional psychosocial support from the oncologist treating them, 40.6% of the patients wished support from the oncologist and additionally from a psychotherapist or social worker. Interest in professional psychosocial support correlated with the amount of distress, but not with sociodemographic variables. CONCLUSIONS: Results stress the importance of training programs for oncologists in order to improve their ability to detect psychosocial distress in cancer patients and to offer adequate emotional support to them.     

Review of Learning disabilities and brain function: A neuropsychological approach (rev. ed.).

Reviews the book, Learning disabilities and brain function: A neuropsychological approach (rev. ed.), by William H. Gaddes (1985). The neurological substrata of intellectual functioning have long been a topic of interest to psychologists; but with the development of the learning disabilities classification and the interest in the brain, learning behavior relationships have expanded to include the entire educational community. This book, like the first edition, has been designed to draw together the neuropsychologist, the school psychologist, and teacher in common cause. In doing so, it helps to bridge a traditional interdisciplinary communications gap. There is a need for neuropsychological training of school psychologists. This book helps to bring this knowledge to bear directly on practice in the field of learning disabilities. Advantages of the second edition over the first are the inclusion of discussions of new techniques (i.e., new brain scanning devices and methods, new applications of dichotic listening) and expanded examples of case studies. The reviewers feel that Gaddes has provided an updated, thorough treatment of the role of neuropsychology in the diagnosis and remediation of the learning-disabled child.

An Instrument to Measure Cutaneous Blood Flow Using the Doppler Shift of Laser Light

A system utilizing the Doppler shift of monochromatic laser light has been developed to measure blood flow in skin. Light from a low power (S mW) He-Ne laser is coupled into a quartz fiber and transmitted to the skin. This light is reflected from both the nonmoving tissues (reference beam) and moving red blood cells (Doppler shifted beam), received by a plastic fiber, and transmitted back to a photodiode where optical heterodyning occurs. The heterodyned output signal, which is proportional to the Doppler shift frequency, is amplified and both RMS and dc values obtained. The RMS value is weighted against the backscattered light intensity using the measured dc value as an index of total received power. This is used as the output flow velocity value.     

Synthesis and mutagenicity of a series of nitrated carbazoles and hydroxycarbazoles

The effects of a component of an Oriental medicine and green tea plants utilized for the traditional beverage on the proliferation of mesangial cells were determined in terms of the 3H-thymidine uptake. When magnesium lithospermate B was added to the medium of the mesangial cell culture, it suppressed the proliferation of mesangial cells at a concentration of 50 micrograms/ml. The 3H-thymidine uptake began to display an inhibitory action from the 6.25 micrograms/ml (-)-epicatechin 3-O-gallate, (-)-epigallocatechin 3-O-gallate or green tea tannin mixture, showing a more conspicuous inhibition at 50 micrograms/ml that did the magnesium lithospermate B at the corresponding concentration. In particular, (-)-epigallocatechin 3-O-gallate, the predominant component of the green tea tannin mixture, exerted an inhibitory effect at a relatively low concentration.     

Intradimensional reversal shift performance in brain-damaged and chronic alcoholic patients.

Examined impaired set-shifting behavior frequently reported in brain-damaged Ss. Using a simple E-paced, 2-choice, visual, intradimensional reversal shift task, samples of brain-damaged (n = 24), alcoholic (n = 28), and control (n = 24) male patients were compared on errors, reaction time, and behavioral impulsivity (finger lift before signal). Alcoholic Ss were not significantly different from controls on any of the measures. As expected, brain-damaged Ss had significantly more total errors, longer reaction times, and higher impulsivity scores than controls. Differences in errors appeared to be due to difficulty in maintaining the perceptual and motor set rather than in set shifting. The importance of investigating disruptions in set maintenance in the performance of brain-damaged Ss is emphasized. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Models of counselor development or training models for supervision? Rejoinder to Stoltenberg and Delworth.

This rejoinder to Stoltenberg and Delworth's comments on my earlier article on developmental models of supervision focuses on three critical issues in the investigation of these models: (a) the distinction between models of becoming a counselor and models of training in counselor education; (b) the methodological issues in the investigation of counselor development and supervisory relationships; and (c) the characterization of conceptual level as a content-specific variable.

An Equivalent CTL Formulation for Condition Sequences

A condition system is a form of Petri net that interacts with other condition systems and the environment via state-based signals called conditions. The condition language framework has been used in previous papers to characterize the input/output behavior of such interacting systems, as well as to specify desired control behavior among other things. In this paper, we show that condition sequences (the specification) and condition systems (the model of the system) have an equivalent structure in the computation tree logic (CTL) framework. The primary goals of this work are to be able to utilize existing tools for program verification for our systems, and to make our work more accessible to the temporal logic community.     

Quantification of cytokines involved in wound healing using surface plasmon resonance

Sensing of three cytokines related to chronic wound healing, interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha), with detection limits at or below 1 ng/mL in buffered saline solution and spiked cell culture medium (CCM) has been achieved. Fiber-optic surface plasmon resonance (SPR) sensors are coated with an antibody binding layer and antibodies specific to the cytokine of interest are covalently attached to this layer. To achieve such detection limits in a complex medium such as CCM, total protein content of 4 mg/mL, the use of a novel N-hydroxysuccinimide ester of 16-mercaptohexadecanoic acid (NHS-MHA) is necessary. A comparison of the detection limits for IL-6 using currently widely used CM-dextran and NHS-MHA shows an improvement by a factor of 3 using NHS-MHA. The detection limits for the monitoring of cytokines in spiked saline solutions and CCM were similar for TNF-alpha and slightly higher for IL-1 and IL-6. The detection of each cytokine in the presence of interfering agents resulted in concentration prediction well within the error of calibration. The SPR sensors are stable in CCM after 20 min of pretreatment in CCM, minimizing the reliance on a reference sensor to quantify the cytokines in complex media. This technique enables a major advancement in the field of real-time monitoring of biologically relevant molecules in complex biological fluids.
