cluster analysis of childhood temperament data on adoptees.cluster analysis is used with behavioral data on 162 adoptees to assess temperament and to test the validity of the temperament typologies described by thomas and chess. data are divided into two groups by sex. results concur with the thomas-chess findings in identifying three main temperament groups: difficult, easy, and slow to warm up. membership in the difficult group predicted later childhood behavior disorder in both sexes. differing environmental factors associated with difficulty for mal ...19807406035
foreign body aspiration of grass inflorescences as a cause of hemoptysis.although the sparsity of reports in the literature suggest aspiration of grass inflorescence is rare, in certain areas of the southern united states, aspiration of this type of foreign body is not so uncommon. four cases of aspiration of hordeum pusillium, often referred to as "cheat grass" are reported: three of the four patients had hemoptysis. the highest incidence of inhaled foreign bodies usually occur in young children, but all our four patients were older children or adolescents. the clin ...19807398419

visual short-term memory and aging in chess players.young (m = 20 years) and older (m = 54 years) equally skilled chessplayers reconstructed slides of chess diagrams shown for 1, 2, and 4 sec either immediately or following 15 sec of interpolated processing. recall was more accurate for younger players, with the gap widening as viewing time increased. interpolated processing decreased accuracy and increased retrieval time equally in the two groups. measures of chunking indicated no age-related differences. these results imply that there is an age ...19817264247
search heuristics of chess players of different calibers.information-processing models of chess-playing ability have distinguished between players of different calibers solely in terms of perceptual encoding and recognition of chess configurations. a reanalysis of degroot's verbal protocols of 1965 indicates that players of different calibers direct their attention toward different areas of the board. grandmasters and masters consider squares that are affected by many pieces, while lesser players direct their attention toward squares on which the piec ...19827180947
[effect of parameters of spatio-structural stimuli on evoked potentials of the visual and posterior associative regions of the cortex in man].in subjects with normal vision, differences have been detected in the reactions of the main components (p100, n150, p200) of evoked potentials recorded in the oz and tpo leads, to homogeneous stimuli, chess fields with different sizes of cells and grids differing in area and the number of orientation stripes. the data obtained are discussed in the light of v.d. glezer's hypothesis on specialized information processing in the visual and posterior associative cortical areas and concepts on the exi ...19827164577
[maturation of evoked potentials to patterned stimuli, and sensitivity of the visual system to deprivation].a study was made of age peculiarities of eps to spatially structurized stimuli in the shape of chess fields with different dimensions of their cells in children and juveniles with normal vision, aged from seven to seventeen. heterochroneity has been established in maturation of eps to a homogeneous and a spatially structurized stimuli. in accordance with the criterion of "maturity" of the ep to a spatially structurized stimulus, an enhanced probability of "mature" eps appearance was observed wit ...19827158033

[play, an indicator of the health of children].africans attach much importance to the fact that their children like to play. a child who is not hungry and refuses to play is not in good health. when a sick child wants to play again one can be sure that his health is improving. thus, play can be a health indicator and can help to form a diagnosis. moreover, the way the child plays is a mental health indicator. during games one can distinguish the leaders who are mentally well-balanced, those who try to cheat and who must be carefully watched, ...19854093132

[use of visual evoked potentials in neurology--a review. i].in 1972, halliday and co-workers [13] inaugurated the rotary mirror method for producing the visually evoked potential (vep) by means of pattern reversal. the so-called pattern reversal vep (prvep) is at present frequently obtained by means of a television monitor (tv stimulation) or light-emitting diode system (led system). independent of its special advantages and disadvantages, the stimulation by means of these systems as compared to the simple flash stimulation potentials seems to evoke with ...20144013563
chemical shift selective mr imaging using a whole-body magnet.we have applied a new method for separating water and fat resonances in proton magnetic resonance (mr) imaging to human studies using a whole-body mr imaging system at 2.0 t. chemical shift selective (chess) mr imaging provides either a water or fat image in a single experimental run within the same time needed for a conventional composite image. although the technique requires a spectral resolution of about 1 ppm over the entire imaging region, first images of the human head and hip indicated t ...19854011907

convergence among assessments of temperament in the first month.this study was designed to assess the potential convergence of 3 approaches to the description of temperament in the first month of life and to identify which aspects of early temperament are most meaningful to mothers. 48 newborns were tested with the brazelton neonatal behavioral assessment scale (nbas). 2 weeks later, mothers responded to the rothbart infant behavior questionnaire (ibq). 2 weeks thereafter, mothers were interviewed in accordance with the thomas, chess, and birch new york long ...19863948594
[methods of evaluating the efficacy of combinations of aminoglycosides with penicillins and their value for the possibility of predicting the therapeutic effect in patients].the efficacy of the combinations of aminoglycosides and penicillin with respect to pseudomonas, klebsiella and escherichia strains was estimated with the methods of two-fold serial dilutions of aminoglycosides and constant concentrations of penicillin and the "chess board" method. correlation between the synergistic effect and sensitivity of the strains to separate components of the combinations was observed. for prediction of the combination efficacy these methods are not useful, since they are ...19853927835
[an immunoenzyme method of determining benzylpenicillin in biological substrates and its antibodies in immunized animals].lately it appeared to be necessary to develop-alternative methods for control of antibiotic therapy. detection of low molecular substances based on the immunoenzymatic assay (iea) is one of the most promising approaches to the development of such methods. the authors developed a quantitative method for determination of benzylpenicillin (bp) according to the procedure described earlier by van weemen. the bp antisera were prepared by immunization of rabbits with a conjugate of bovine serum albumin ...19853888100

roundtable: what is temperament? four approaches.4 current approaches to understanding temperament are discussed in the roundtable. in an introductory overview, goldsmith outlines some of the major convergences and divergences in the understanding of this concept. theorists representing 4 positions--goldsmith, buss and plomin, rothbart, and thomas and chess--outline their views by responding to each of 6 questions: how do you define temperament and explain the boundaries of the concept? what are the elements of temperatment? how does the const ...20133829791
darwinian evolution in games with perfect information.we consider a model of darwinian evolution in games with perfect information like chess or checkers. the evolution is viewed as a sequence of strategies, each of which wins over its immediate predecessor. we argue that the intelligence level of strategies need not necessarily increase during this type of evolution.19873828402
the impact of temperament in a school setting: an epidemiological study.the authors present the results of an epidemiological study on a large non-clinical population-based sample of french speaking seven year-old children (n = 596) whose aim was to verify if a relation exists between temperament and outward-type or inward-type behavior problems in school. the thomas and chess' parent temperament questionnaire, filled out twice by the parents over a four-week interval, was used to determine temperament. the conners teacher questionnaire, filled out twice by the teac ...19863756750
multipurpose nmr imaging using stimulated echoes.steam (stimulated-echo acquisition mode) imaging techniques recently introduced by the authors are demonstrated to provide a versatile tool for improving the parametric specificity in nmr imaging. stimulated echoes can be excited by a sequence of at least three rf pulses with flip angles of 90 degrees or less. the main characteristics of the steam method are based on the great functional flexibility of an imaging sequence comprising three rf pulses unequal to 180 degrees and three intervals prio ...19863747817

multiple chemical shift selective (chess) mr imaging using stimulated echoes.recently, stimulated echo acquisition mode (steam) magnetic resonance (mr) imaging has been demonstrated as a new tool for multiparametric mr imaging studies. applications of the chemical shift selective (chess) steam technique using a 2.0-t whole-body mr imaging system are reported in which a series of contiguous cross-sectional images of the head and the pelvis were acquired. because selective excitation of the desired component is employed rather than elimination of the unwanted component, th ...19863737919
[relation between sleep and processes of retention and mental activity].the structure of nocturnal sleep was studied in two groups of subjects: the group i subjects had been given 60 unfamiliar english words to learn, whereas group ii subjects had been playing games of chess. the paradoxical sleep (ps) latency in the 1 st cycle, the type of falling into the ps, and intensity of rapid eye movements were recorded. no reliable difference was found in the sleep structure of both test groups. no correlation either was observed between the sleep characteristics and the qu ...19863732546
cartilage disorders: comparison of spin-echo, chess, and flash sequence mr images.magnetic resonance (mr) imaging is known to be a suitable modality for the visualization of the hyaline cartilage and the fibrocartilage joint structures. to compare standard spin-echo (se) images with water images obtained with the chemical shift selective (chess) sequence and with the fast low angle shot (flash) sequence, examinations were performed with all three sequences in eight volunteers and 28 patients with inflammatory degenerative and traumatic alterations of the knee, hip, and sacroi ...19873615875
a model for emmetropization: predicting the progression of ametropia.the response of a second-order feedback system is used to describe the controlling process that regulates the refraction of the human eye to achieve optimal visual acuity over the years (emmetropization). from data collected in past refractions, the equation of the feedback system has been derived for individual eyes and used to predict changes in their refraction with age with an accuracy of 0.50 diopters for 89.1% of the eyes tested. if the model is applied to other populations, the root mean ...19873614846
gradient reversal technique and its applications to chemical-shift-related nmr imaging.the chemical-shift effect often degrades slice selectivity thereby degrading the contrast and spatial resolutions in a high-field nmr imaging. we propose a new pulse sequence which can compensate for this chemical-shift effect during slice selection. this technique provides correct slice definition as well as clear separation between water and lipid protons in high-field proton nmr imaging. particular applications of this technique are 2d imaging with a thin-slice selection and chunk 3d imaging, ...19873613953
[testing of visual function by the evoked potential method before and after surgical treatment of optico-chiasmal arachnoiditis].dynamics of changes of visual evoked potentials recorded in patients with optico-chiasmatic arachnoiditis in response to a flash of light were revealed during restoration of visual function in the postoperative period. in improvement of visual functions no changes were found of evoked potentials recorded in a chess pattern in the immediate postoperative period.20083564794

[various characteristics of gene localization in eukaryotic chromosomes. formulation of a problem and analysis of non-random localization of mating type loci in fungi].we have denoted two possible models of gene order evolution as the "card" and "chess" models. the first suggests random shuffling of genes during evolution, the second--non-random gene transposition, gene order being checked by natural selection. we discuss here localization of the mating type locus in fungal genomes. in 8 of 10 genetically well studied species of ascomycetous fungi, the mating type locus is linked to a centromere; in one species, it segregates regularly during the second meioti ...20123542707
terminal distributions along a 'knight's line' for a stochastic epidemic.the model under consideration relates to the spread of a disease in a finite population where removal of infectives is allowed to occur. it is equivalent to a restricted random walk over a discrete grid of points interior to a trapezium. we consider an artificial barrier on the grid at which the epidemic ceases. the barrier is a semi-diagonal resembling the path of the knight in chess and allows some simplification of the analysis. in particular, we investigate the probability distribution along ...19873503088

the role of theories of cognitive aging: comment on salthouse.cognitive models of aging ought, minimally, to simulate age effects for a broad range of tasks, and their underlying assumptions ought to be constrained by existing data on cognitive mechanisms. salthouse's model (and other parallel distributed-processing network models) meets the first criterion better than it meets the second. another weakness is in its inability to account for goal-directed behavior. thus, models like that of salthouse seem best suited to the description of automatic informat ...19883268238
[doppler and valvular prostheses].the principle of examination of prosthetic valves is not different from that of the original valves in terms of bioprosthesis. on the contrary, mechanical prosthesis are markedly opaque to ultrasounds and cause masking and non-flow phenomena behind the prosthesis, which are capable to completely hide abnormal retrograde flows, in traditional views (apical 4 cavities to demonstrate a mitral leakage). therefore, with mechanical prostheses, it is necessary to "cheat" and use atypical views which av ...20113223725
a comparison of selective saturation and selective echo chemical shift imaging techniques.we report on a comparative study of two methods of chemical shift imaging which can be used to selectively image fat and water in vivo. both methods require a b0 field sufficiently homogenous to resolve the methylene and water spectral lines. one method, called chess, uses a chemically selective pulse to saturate the unwanted spectral line. the other method, called secsi, achieves chemical selectivity by using a soft 180 degree rf pulse in forming a spin echo image. both methods require that the ...19883185136
standardized clinical evaluation of depressive and anxious symptomatology.the main standardized instruments for clinical assessment of depression and anxiety are diagnostic criteria, rating scales, and mental tests, mainly questionnaires. the systematic use of rigorous diagnostic criteria is useful in recruiting sufficiently homogeneous patient groups for clinical research. the polydiagnostic system represents, in this perspective, a stimulating trend of research, as it is not linked to a sole nosographic reference system. some rating scales have recently been develop ...19883180118
trends in temperament research.the paper focuses on current concepts of temperament that has led to different approaches within the field of temperament research. the concept of temperament has interested scholars from ancient greece until modern european and american research teams. also in soviet psychology temperament is getting attention. in finland temperament research has advanced on two different lines. there is widespread agreement that temperament is a group of related traits and not just one trait attributed to the ...19883067510

cns and pns effects of nimodipine.calcium ions play a decisive role in a large number of processes dealing with development, regeneration after damage, and aging of elements of the nervous system. nimodipine, a member of the 1,4-dihydropyridine chess of calcium-channel blockers, has proved to influence the calcium metabolism of neurons. this review focuses on the results of recent studies on the role of nimodipine in both the central and peripheral nervous system, during or after events that threaten the integrity or function of ...19902074438

[a controlled double-blind study of tetrabamate versus lorazepam and placebo in generalized anxiety].the anxiolytic efficacy of tetrabamate was evaluated in a multicentric double-blind study versus lorazepam and placebo, in 269 patients with a generalized anxiety disorder according to dsm iii-r criteria. the anxiolytic activity of tetrabamate (at 900 mg/day) was significantly superior than that of placebo from day 7 of treatment and equivalent to lorazepam efficacy (at 4.5 mg/day). in the tetrabamate group, 55.3% were considered as "good responders" (as defined by a hars score reduction equal o ...20131959498
rook's tour representation of the genetic code.disconnected recurrences of the stop signal, serine and arginine appear in the original representation of the genetic code, and of the stop signal, arginine, serine and leucine in the codon ring representation. to achieve connectedness along with structural continuity, a rook's tour representation is presented here. on the basis of structural similarities and disparities in their side groups, each of the 20 amino acids is associated with a domain comprised of from one to six contiguous squares o ...19911958894
aspects of skilled imagery in blindfold chess.blindfold chess is a very good task environment to study skill-based mental images or skilled imagery. seven experiments providing information on different aspects of skilled imagery in blindfold chess were made. in all experiments very clear skill-related differences in the operation of chess-specific materials could be found. it will also be argued that chess-specific patterns or chunks are important in skilled subjects' construction of images and the operation of these images relies on the co ...19911950637
combined chemical-shift and phase-selective imaging for fat suppression: theory and initial clinical experience.incomplete fat suppression with a chemical-shift-selective (chess) or phase-selective (dixon) technique is partially due to the olefinic fat component, which precesses at the same frequency as water. the authors developed a new method of fat suppression--the opposed-fat saturation (op-es) sequence--that combines both techniques to obtain superior fat saturation. fat suppression was verified in phantom studies, which showed that the chess portion can eliminate most of the aliphatic fat signal exc ...19911887054
cognitive advantage in sport: the nature of perceptual structures.to extend and clarify the nature of the perceptual processes used by sport experts to perceive schematic sport information, two experiments used schematic football diagrams that varied in structure (structured vs. unstructured) and complexity (complex vs. easy). the primary objective was to examine and characterize the nature of the perceptual structures (chunks) that are initially encoded, stored, and subsequently retrieved. in experiment 1, compared with nonexperts, experts recalled larger per ...19911862820
