This study considers whether Unified English Braille provides an efficient representation of printed English. Two databases of English words were used to acquire and calculate information about English orthography that was then used to analyze Unified English Braille (UEB) using a computer program developed by the second author. In general, braille groupsigns and wordsigns represent many of the most frequently occurring letter combinations and words in English. However, there were some braille contractions that are so infrequent, they appear fewer than 100 times per million words or did not appear in the database at all. There was good braille representation within the 50 most frequent words, and our efficiency index showed that braille is already extremely efficient, although there is some mismatch between the order of introduction for braille and the frequency of certain words and letter combinations in English. There is a common understanding that we should teach all of the contractions by the end of third grade, but our results show that some contractions, many of which are shortform words, never appear in school texts. It may be possible to approach instruction of shortform words in a different way.

Purpose: to evaluate the effectiveness, safety, and predictability of the wavefront-guided FemtoLASIK using the Platoscan computer program and data from the KR-1W aberrometer, in comparison with the conventional algorithm FemtoLASIK in patients with low to moderate myopia.Patients and methods. There were 62 eyes of 62 patients with low to moderate myopia who had undergone FemtoLASIK procedure using an excimer laser ‘Microscan Visum” (Russia) and a femtosecond laser Femto LDV Z6 (Switzerland) in the study. In the “Wavefront” group which included 31 eyes with a mean spherical equivalent (SE) -=3,32 ± 1,23 D (M ± SD) was performed a wavefront-guided Femtosecond LASIK using aberrometer KR-1W (Japan) and a program for calculating the operation’s parameters “Platoscan” (Russia). “Standard” group included 31 eyes with an average SE –3.51 ± 1.21 D (M ± SD), who received the conventional FemtoLASIK. The “Wavefront” and “Standard” groups were comparable in terms of pre-operative data (age, sex, corneal curvature, central thickness of the cornea, sphere, cylinder, SE) (p > 0.05). All patients underwent complete ophthalmological examination before refractive laser surgery, and also patients were examined on the 1st day and 1 month after FemtoLASIK.Results. One month postoperatively, in the “Wavefront” group the UDVA 1.0 or better (20/20 or better by Snellen) was achieved in 93.5%, in the “Standard” group — in 96,8% (p > 0.05). There wasn’t observed a loss of the CDVA lines in both groups. In the “Wavefront” group, gain of one or more lines of the CDVA was in 38.7%, in the “Standard” group — in 12.9% (p = 0.04, Fisher’s exact test). In the “Wavefront” group the predictability of targeted refraction within ±0.5 D was in 93.5%, within ±1.0 D — in 100%, in the “Standard” group — in 90,3 and 100%, respectively (p > 0.05). The efficiency index in the “Wavefront” group was 1.00 (1.00; 1.20) (Me (Q25; Q75)), in the “Standard” group — 1.00 (1.00; 1,00) (Me (Q25; Q75)) (p > 0.05). The safety index in the “Wavefront” group was 1.00 (1.00; 1.20) (Me (Q25; Q75)), in the “Standard” group — 1.00 (1.00; 1,00) (Me (Q25; Q75)) (p > 0.05).Conclusions. The FemtoLASIK procedure, performed according to the conventional and wavefront-guided algorithms using the “Platoscan” computer program and data from the KR-1W aberrometer, is an effective, safe and predictable method for correcting low to moderate myopia, there is no statistically significant difference between two algorithms (p > 0.05).

Association Matrix

Simuread is a computer program which segments traditional English orthography into minimum graphic signals and designates a segmental phoneme, non phoneme, or phoneme combination for each. The segmental phoneme chains required for the oral representation of the orthography are simulated in numeric output. The program also derives a conditional association matrix. The rows of the matrix are the minimum graphic signals and the columns are the phoneme designates. The row totals and the percentages of specific graphic-phoneme associations are computed for the cells of the matrix. Samples of Simuread processing of various texts, a portion of a conditional association matrix and comparisons of the total occurrences of the graphic units in several first grade readers are presented in this article to illustrate its research applications.

The Given

The article presents a methodology for determining the probability of aircraft information contacting airborne objects within flight test procedures. The methodology is based on the experimental-theoretical test method, based on the application of mathematical modeling. The technique differs from the known ones in that it uses modern information technologies, and the adopted mathematical model is implemented in the form of a computer program. In addition, detecting the given performance indicator in flight experiments is inappropriate because of significant resource costs. This technique is suitable for practical testing purposes and allows determining the aircraft efficiency index when searching air objects – the probability of an information contact with a typical air facility. The presented computer program provides the performance of calculations of the output index for different values and combinations of factors influencing the result. The simulation was performed and the probabilities of the aircraft information contact with typical airborne objects under given conditions were obtained. The results of the influence research on the probability of groups of factors outlet into information contact: the aircraft and the air object characteristics, the quality of the initial information about it, search conditions are presented. As a result of the work, the main regularities are established when solving the problem of the aircraft information contact with an air object. The computer program created within the methodology framework has a modern graphical interface and allows reducing the time spent by the researcher on the processing of test results. The developed technique allows performing a comparative assessment of the aircraft capabilities to detect airborne objects in tests.

In contrast to the adjustment of single plates a block adjustment is a simultaneous determination of all unknowns associated with many overlapping plates (star positions and plate constants etc. ) by one large adjustment. This plate overlap technique was introduced by Eichhorn and reviewed by Googe et. al. The author now has developed a set of computer programmes which allows the adjustment of any set of contemporaneous overlapping plates. There is in principle no limit for the number of plates, the number of stars, the number of individual plate constants for each plate, and for the overlapping factor.

In hexagonal Se crystal each atom is covalently bound to two others to form an endless spiral chain, and in Sb crystal each atom to three others to form an extended puckered sheet. Such chains and sheets may be regarded as one- and two- dimensional molecules, respectively. In this paper we investigate the structures in amorphous state of these elements and the crystallization.HRTEM and ED images of vacuum-deposited amorphous Se and Sb films were taken with a JEM-200CX electron microscope (Cs=1.2 mm). The structure models of amorphous films were constructed on a computer by Monte Carlo method. Generated atoms were subsequently deposited on a space of 2 nm×2 nm as they fulfiled the binding condition, to form a film 5 nm thick (Fig. 1a-1c). An improvement on a previous computer program has been made as to realize the actual film formation. Radial distribution fuction (RDF) curves, ED intensities and HRTEM images for the constructed structure models were calculated, and compared with the observed ones.

Reading And Spelling Difficulties

Purpose Morphological interventions promote gains in morphological knowledge and in other oral and written language skills (e.g., phonological awareness, vocabulary, reading, and spelling), yet we have a limited understanding of critical intervention features. In this clinical focus article, we describe a relatively novel approach to teaching morphology that considers its role as the key organizing principle of English orthography. We also present a clinical example of such an intervention delivered during a summer camp at a university speech and hearing clinic. Method Graduate speech-language pathology students provided a 6-week morphology-focused orthographic intervention to children in first through fourth grade ( n = 10) who demonstrated word-level reading and spelling difficulties. The intervention focused children's attention on morphological families, teaching how morphology is interrelated with phonology and etymology in English orthography. Results Comparing pre- and posttest scores, children demonstrated improvement in reading and/or spelling abilities, with the largest gains observed in spelling affixes within polymorphemic words. Children and their caregivers reacted positively to the intervention. Therefore, data from the camp offer preliminary support for teaching morphology within the context of written words, and the intervention appears to be a feasible approach for simultaneously increasing morphological knowledge, reading, and spelling. Conclusion Children with word-level reading and spelling difficulties may benefit from a morphology-focused orthographic intervention, such as the one described here. Research on the approach is warranted, and clinicians are encouraged to explore its possible effectiveness in their practice. Supplemental Material https://doi.org/10.23641/asha.12290687

Abstract. There is a growing interest in embitterment as psychological concept. However, little systematic research has been conducted to characterize this emotional reaction. Still, there is an ongoing debate about the distinctiveness of embitterment and its dimensions. Additionally, a categorical and a dimensional perspective on embitterment have been developed independently over the last decade. The present study investigates the dimensions of embitterment by bringing these two different approaches together, for the first time. The Bern Embitterment Inventory (BEI) was given to 49 patients diagnosed with “Posttraumatic Embitterment Disorder (PTED)” and a matched control group of 49 patients with psychological disorders with other dominant emotional dysregulations. The ability to discriminate between the two groups was assessed by t-tests and Receiver Operating Characteristic Curves (ROC curve analysis). PTED patients scored significantly higher on the BEI than the patients of the control group. ROC analyses indicated diagnostic accuracy of the inventory. Further, we conducted Confirmatory Factor Analyses (CFA) to examine the different dimensions of embitterment and their relations. As a result, we found four characteristic dimensions of embitterment, namely disappointment, lack of acknowledge, pessimism, and misanthropy. In general, our findings showed a common understanding of embitterment as a unique but multidimensional emotional reaction to distressful life-events.
