study of eating attitudes and body image perception in the preadolescent age.eating attitudes and body image have been studied in a group of 109 girls, pupils of the fifth primary school grade (average age 10 years and 8 months). the children's eating attitude test (cheat) has been used in the study of eating attitudes. the mean questionnaire score is 11.38 +/- 8 with a range of 0 to 45. fourteen girls (12.8%) had a total score higher than 20, making them an eating disorder risk group. a set of seven schematic figures showing silhouettes of girls ranging from very thin t ...199810097438
the endovascular treatment of brain arteriovenous malformations.advances in superselective microcatheterization techniques, which took place in the past decade, established superselective endovascular exploration as an integral and indispensable tool in the pretherapeutic evaluation of brain avms. the strict and routine application of superselective angiography furthered our knowledge on the angioarchitecture of brain avms, including vascular composition of the nidus, types of feeding arteries and types and patterns of venous drainage. in addition, various t ...199810050213
how shall we speak of children's personalities in middle childhood? a preliminary taxonomy.developmental researchers have neglected the study of personality traits in middle childhood, thus leaving unanswered many questions about childhood personality structure. this article presents a developmental framework for understanding personality in middle childhood and critically reviews 5 models of temperament and personality structure in this age range: the models of a. thomas and s. chess, a. h. buss and r. plomin, m. k. rothbart, j. block and j. h. block, and the big five. a number of ro ...19989849111
[osseous reconstruction of the patella with screwed autologous graft in the course of repeat prosthesis of the knee].the aim of this study was to propose an original way of solving the infrequent but difficult problem of a thin patellar remnant. after removal of the loose patellar button of a knee prosthesis, several options are available: patellectomy should be avoided because of unpredictable results; patelloplasty may be the solution if bone quality is too poor and can allow for its improvement with time; recementing a new implant needs the remaining patella to be thick enough (more than 10 millimeters).19989775038

expert chess memory: revisiting the chunking hypothesis.after reviewing the relevant theory on chess expertise, this paper re-examines experimentally the finding of chase and simon (1973a) that the differences in ability of chess players at different skill levels to copy and to recall positions are attributable to the experts' storage of thousands of chunks (patterned clusters of pieces) in long-term memory. despite important differences in the experimental apparatus, the data of the present experiments regarding latencies and chess relations between ...19989709441
automation in urodynamics.the information concerning bladder function during voiding and the size of the outlet resistance is found in relation to detrusor pressure and urinary flow (pressure flow plot). the lowest detrusor pressure during voiding (low-pressure flank) contains information on mechanical resistance (passive urethral resistance relation, purr). the purr curve is defined using foot point (cross-section with pressure axis) and slope. an increasing foot point as well as a decrease in the slope of the purr curv ...19989705553
expert memory: a comparison of four theories.this paper compares four current theories of expertise with respect to chess players' memory: chase and simon's chunking theory, holding's seek theory, ericsson and kintsch's long-term working memory theory, and gobet and simon's template theory (chase, w.g., simon, h.a., 1973a. perception in chess. cognitive psychology 4, 55-81; holding, d.h., 1985. the psychology of chess skill. erlbaum, hillsdale, nj; ericsson, k.a., kintsch, w., 1995. long-term working memory. psychological review 102, 211-2 ...19989677761
apperception and imagery in blindfold chess.apperception constructs functional and "meaningful" mental representations. these representations are often built on mental images. hence it is rational to assume that the contents of some parts of images may be functionally more important than others. this means that the cognitive processing of some parts of the image is more effective than for others. to extract this preferential structure, which we call the functional figure in mental images, five experiments were conducted on blindfold chess ...19989640433
analysis of outcome after thermotherapy using different classifications of bladder outlet obstruction.the urodynamic profiles of 97 patients with benign prostatic hyperplasia undergoing low-energy transurethral microwave thermotherapy (tumt) for lower urinary tract symptoms were analysed using the abrams/griffiths nomogram, the urethral resistance algorithm, the linpurr, schäfer nomogram, and the chess classification. a significant clinical response was seen for the whole group, as shown by changes in symptom score, free flow rate, and residual urine. the best symptomatic response was identified ...19989514143
a path model of whitewater boating satisfaction on the cheat river of west virginia/ recreation satisfaction is a complex psychological construct that is difficult to define and measure. recent approaches suggest that overall satisfaction may be a function of multiple satisfactions derived from specific elements of a recreation experience such as the situational characteristics of a recreation setting or activity and the recreationist's subjective evaluations of the experience. in this paper, a path model of whitewater boating satisfaction was tested using data from a survey o ...19989419289

antigen retrieval techniques in immunohistochemistry: comparison of different methods.routine sections of normal and pathological samples fixed in 10 per cent buffered formalin or b5, including edta-decalcified bone-marrow biopsies, were tested with 61 antibodies following heating in three different fluids: 0.01 m citrate buffer (ph 6.0), 0.1 m tris-hcl (ph 8.0), and 1 mm edta-naoh solution (ph 8.0). the sections underwent either three cycles of microwave treatment (5 min each) or pressure cooking for 1-2 min. the alkaline phosphatase/anti-alkaline phosphatase (apaap) technique w ...19979370957
a reexamination of gilligan's analysis of the female moral system : distaff altruism will not succeed.gilligan's (1982) refinement of kohlberg's theory on moral development operates on two theses: (1) females, more so than males, reach moral decisions based on the personalities of the relevant individuals; and (2) female behaviors stemming from moral decisions are based upon "care" and "responsibility for others." this article accepts the first thesis but argues that the second is incorrect. that is, self-interest-i.e., aiding "blood" kin and/or carefully monitoring reciprocity-rather than "altr ...199726196966
improved water and lipid suppression for 3d press csi using rf band selective inversion with gradient dephasing (basing).a t1 insensitive solvent suppression technique-band selective inversion with gradient dephasing (basing)-was developed to suppress water and lipids for 1h magnetic resonance spectroscopy (mrs). basing, which consists of a frequency selective rf inversion pulse surrounded by spoiler gradient pulses of opposite signs, was used to dephase stopband resonances and minimally impact passband metabolites. passband phase linearity was achieved with a dual basing scheme. using the shinnar-le roux algorith ...19979256113
evolution's 'missing link': a hypothesis upon neural plasticity, prefrontal working memory and the origins of modern cognition.many activities such as reading, mathematics and chess depend upon cognitive processes which arose after our evolution. why could they arise if not evolved? i argue four things fortuitously came together to make our nonevolved cognitive skills possible: (i) neural plasticity; (ii) large functionally uncommitted prefrontal, temporal and parietal cerebral cortices; (iii) the ability of their neural circuits (due to neural plasticity), if trained, to take on novel symbolic and nonsymbolic skills; a ...19979247893

templates in chess memory: a mechanism for recalling several boards.this paper addresses empirically and theoretically a question derived from the chunking theory of memory (chase & simon, 1973a, 1973b): to what extent is skilled chess memory limited by the size of short-term memory (about seven chunks)? this question is addressed first with an experiment where subjects, ranking from class a players to grandmasters, are asked to recall up to five positions presented during 5 s each. results show a decline of percentage of recall with additional boards, but also ...19968812020
recall of rapidly presented random chess positions is a function of skill.a widely cited result asserts that experts' superiority over novices in recalling meaningful material from their domain of expertise vanishes when they are confronted with random material. a review of recent chess experiments in which random positions served as control material (presentation time between 3 and 10 sec) shows, however, that strong players generally maintain some superiority over weak players even with random positions, although the relative difference between skill levels is much ...199624213863
