Abstract
For most students with intellectual disability (ID), education in the least restrictive environment has been determined to be separate special education classrooms. One means to promote greater participation in general education classrooms is for educators to identify and arrange individualized supports that students need to be successful. We conducted focus group interviews with 33 educators in 6 schools from 3 states to explore how they currently plan supports for their students, obtain their opinions on the usefulness of a systematic problem-solving process for supports planning, and gather their perspectives on resources, including the nature of technical assistance, that would be most helpful in planning individualized supports. Themes from the focus group interview transcripts were identified and recommendations for increasing educator competencies in planning and monitoring individualized supports for students with ID in general education classrooms are provided.

Published: February 2020

Phase-shifting techniques are one of the most promising strategies to extract the phase information and retrieve the parameters of interest (e.g., refractive index, beam collimation, object shape, deformations, thickness, focal length, etc.) from interferograms. However, traditional phase-shifting techniques suffer from both internal and external noise, which reduce measurement accuracy. This paper reports a comparative analysis of the three commonly used filtering techniques, namely, Fourier, windowed Fourier, and wavelet filtering for noise reduction and accurate extraction of phase information from phase-shifted interferograms. Toward this, two basic types of noise (additive and multiplicative noise) are introduced in the simulated interferograms and processed using the pre-filtering strategies. The effect of second-order harmonics in the presence of noise is also examined. In addition, experimental demonstrations of the real-life applicability of the analyses are provided using the interferograms recorded on coherent (Talbot) and incoherent (Lau) grating shearing interferometers. High accuracy in the measurement of defocusing error of the lens is obtained using the filtering strategies. Further inferences and insights are drawn in favor of the pre-filtering techniques.

Authors: Nursam Natalita Maulani 
Published: February 2020

Sel surya tersensitasi pewarna atau dye-sensitized solar cell (DSSC) merupakan sel surya generasi ketiga yang teknologinya sangat menjanjikan untuk untuk menjadi alternatif sel surya berbasis silikon. DSSC umumnya memiliki dua bagian utama, yaitu working electrode (anoda) dan counter electrode (katoda). Counter electrode memiliki peran krusial pada DSSC, utamanya sebagai katalis untuk mempercepat reaksi reduksi-oksidasi pada elektrolit. Dengan demikian, pemilihan jenis material pada bagian counter electrode memiliki pengaruh signifikan terhadap performa DSSC secara keseluruhan. Platina merupakan salah satu material yang sangat umum digunakan pada counter electrode DSSC dikarenakan karakteristiknya yang hampir mendekati counter electrode ideal. Material counter electrode lain seperti karbon dan poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) juga digunakan sebagai alternatif counter electrode platina yang memiliki harga yang mahal dan persediaan terbatas. Dalam paper review ini akan dibahas mengenai berbagai usaha yang dilakukan untuk meningkatkan performa DSSC menggunakan counter electrode platina, karbon dan PEDOT:PSS. Usaha tersebut meliputi peningkatan aktivitas katalis, konduktivitas, porositas, dan luas permukaan counter electrode. Beberapa penelitian telah membuktikan bahwa karbon dan PEDOT:PSS mampu menghasilkan performa DSSC yang mendekati dan bahkan melebihi counter electrode platina. Pengaruh variasi metode deposisi dan jenis komponen lain seperti fotoanoda, dye, dan elektrolit terhadap performa DSSC dengan counter electrode platina, karbon dan PEDOT:PSS juga dibahas dalam paper ini. Pemilihan material dan komponen DSSC yang sesuai, sangat penting dilakukan untuk menghasilkan sel surya dengan performa tinggi.

Włodek Roman, Joseph Green, producent polskich filmów jidyszowych [Joseph Green, producer of Polish Yiddish-language films]. „Images” vol. XXVI, no 35. Poznań 2019. Adam Mickiewicz University Press. Pp. 77–101. ISSN 1731-450X. DOI 10.14746/i.2019.35.04.
Joseph Green (1900–1996), born Josef Chaim Grinberg in Łódź, was one of the most important producers of films in Yiddish. At the beginning of the sound era in the United States, he worked on dubbing in Yiddish for Jewish films, including Joseph in the Land of Egypt. He received a copy of the film as a royalty, which he then used with great success. The money helped him produce four Jewish films in Poland between 1936 and 1938: Yiddle with His Fiddle, The Jester, Little Mother and A Letter to Mother. Green left Poland in the spring of 1939. When the world of Shtetls – evoked by him – disappeared as a result of the Second World War, he ceased making films.

Published: February 2020

Abstract
Aluminium Covetic metallurgical synthesis along with the characterization of cast material results were presented in this paper. Aluminium- 3% graphite (carbon) composites were fabricated by applying different voltages and amperages of direct current through the stir-casting process. This process, called Covetic based on patent applications of Third Millennium Metals. Obtained casts were tested for their chemical composition, density, tensile strength, hardness, microstructures, and electrical conductivity measurements using an Oxford PMI-Master Pro spark emission spectrometer, a DA-300M density measurement device, a WDW-200 universal tensile test machine, a HBA-3000S automatic Brinell Hardness Tester, a scanning electron microscope with Energy-Dispersive Spectroscopy and an AT512 Precision Ohmmeter, respectively. Moreover, increasing of amperages and/or decreasing of voltages of direct current ensured considerable increasing of electrical conductivity (≈ 34%), the notable decrement in the density (≈ 0.94%), an enhancement in the tensile strength (≈ 18%) and the hardness (≈ 15%) of aluminium Covetic casts compared to the parent metal. In summary, results show that the increasing of amperages and/or decreasing of voltages of direct current has a superior influence on improving electrical conductivity of aluminium-graphite Covetic casts with better mechanical properties.

Published: February 2020

Abstract
Process of ready mixed concrete (RMC) delivery is an example of multi-objective optimization due to the conflicting objectives of the parties involved. In order to face this problem, discrete event simulation model of the delivery process is created with input parameters based on the surveyed data of real processes. The model is simulated with different vehicle dispatching policies and the results are analysed focusing on performance indicators. The research results compared in terms of Pareto optimality indicate that employing effective dispatching strategies can reduce both site idle time and waiting time of vehicles.

AbstractBackgroundThe optimal duration of antibiotic treatment for complicated parapneumonic effusions (CPPEs) has not been properly defined. Our aim was to compare the efficacy of amoxicillin-clavulanate for 2 vs. 3 weeks in patients with CPPE (i.e. those which required chest tube drainage).MethodsIn this non-inferiority, randomized, double-blind, controlled trial, patients with community-acquired CPPE were recruited from two centers in Spain and, after having obtained clinical stability following 2 weeks of amoxicillin-clavulanate, they were randomly assigned to placebo or antibiotic for an additional week. The primary objective was clinical success, tested for a non-inferiority margin of<10%. Secondary outcomes were the proportion of residual pleural thickening of>10 mm at 3 months, and adverse events. The study was registered with EudraCT, number 2014-003137-25. We originally planned to randomly assign 284 patients.ResultsAfter recruiting 55 patients, the study was terminated early owing to slow enrolment. A total of 25 patients were assigned to 2 weeks and 30 patients to 3 weeks of amoxicillin-clavulanate. Clinical success occurred in the 25 (100%) patients treated for 2 weeks and 29 (97%) treated for 3 weeks (difference 3%, 95% CI −3 to 9.7%). Respective between-group differences in the rate of residual pleural thickening (−12%, 95%CI −39 to 14%) and adverse events (−7%, 95%CI −16 to 2%) did not reach statistical significance.ConclusionsIn this small series of selected adult patients with community-acquired CPPE, amoxicillin-clavulanate treatment could be safely discontinued by day 14 if clinical stability was obtained.

Abstract
Micro-surfacing is a cationic mixture for reparation and maintenance of asphalt pavement and contains polymer-modified bitumen emulsion, 100 % manufactured well-graded fine aggregate, mineral filler, water, and chemical additives. The object of this study was to extend the lifespan of a Micro-surfacing mixture against traffic loads to obtain a higher performance asphalt mixture using different additives, including Diatomite filler, nano-zeolite, styrene butadiene rubber, and glass fiber. To evaluate the performance of the mixtures, a variety of experimental tests, including the abrasion test (International Slurry Surfacing Association [ISSA] TB 100), adhesion test (ISSA TB109), and Wet Cohesion test (ISSA TB139) and Scanning Electron Microscopy, were conducted to classify Micro-surfacing quality control against traffic loads. Cohesion test results showed that adding 2 % nano-zeolite and 4 % polypropylene increased loading resistance up to 25 % (Quick Set and Quick Traffic). In addition, using 10 % of Diatomite improved abrasion resistance. It is worth noting that with an increasing dosage of asphalt emulsion, the effect of the additives will also increase. Moreover, adding 0.26 % of glass fiber in the mixtures increased bleeding resistance around 14 %.

Published: February 2020

La presente investigación tiene como objetivo principal integrar los parámetros morfo métricos de la cuenca con la información estadística del Servicio Nacional de Meteorología e Hidrología SENAMHI, para estimación de caudales medio y caudales máximos aplicando, respectivamente las ecuaciones sintéticas y las ecuaciones racionales.
En la primera parte se estimaron los parámetros morfo métricos dela cuenca aplicando el principio de la georreferenciación y superposición de capas vectoriales y raster, utilizando el programa Arc Gis 10.4. Luego mediante la superposición ponderada de mapas temáticos del Ministerio del Ambiente MINAM, se determina el coeficiente de escorrentía para la cuenca del rio Checras.
A continuación se procede hacer la trasformación y tratamiento estadístico de la data histórica de SENAMHI relacionado con registros de precipitación entre 1967 y 2008, obteniéndose la intensidad de precipitación de diseño y la precipitación media de la cuenca.
Con los cuatro parámetros principales identificados: área, coeficiente de escorrentía, precipitación media y la intensidad de precipitación de diseño, se procede a calcular la serie de caudales máximos así como los caudales medios y mínimos del rio Checras. Esto permite caracterizar la cuenca en términos hidrológicos y climáticos.

Published: February 2020

On the 3rd of July, the United Nations General Assembly, taking into consideration the decision of the Statistical Commission, has adopted a Resolution wherein it was decided to designate 20 October 2010 as the World Statistics Day. Aiming to focus on the core values of statistics, such as quality services, in­tegrity and professionalism, the main topic of the celebration will be “Celebrating the many contribu­tions and achievements of official statistics”.
The official Lithuanian statistics meets the World Statistics Day not only by declaring but also by actually implementing the principles of statistics of a democratic state, complying with the standards of European statistics and satisfying the needs of na­tional and foreign users of statistics.
The article gives a brief overview of the path­ways of national statistics stretching 90 years back­wards, the development of statistical thought, statis­tical integration processes in democratic society, as well as discusses the significance of statistical capacity in preparing reliable and timely statistical information necessary to arrive at legitimate political decisions and to inform society, demonstrates the achievements of Lithuanian statistics over 20 years of independence, and mentions key statistical works to be implemented in the nearest future.
Statistical Survey on Household Consumption in the Context of Economic Growth and Decline
Authors: Molienė Ona , Misiūnas Algimantas 
Published: February 2020

The article presents an in-depth analysis of household consumption expenditure in Lithuania in 2005−2008 through the use of not only traditional indicators and methods but also those proposed by the authors of the article. The results of the calcula­tions might be useful in the analysis of the efficiency of the poverty and social inequality reduction policy. The purpose of the article is to reflect the socioeco­nomic stratification of society and its changes across the country, in urban and rural areas. In the survey, different – identification, secondary grouping, sum­mary indicators, and index – methods were used. Tra­ditional and elementary statistical indicators – an arithmetic mean, a mode, and a median – were used for the assessment of the asymmetry of the distribu­tion of expenditure. In summarising structural differ­ences in consumption expenditure, it is proposed to use the Gateva integral coefficient of structural differ­ences; movement in this coefficient helps to reveal shifts in consumption patterns in household groups.
The analysis carried out confirmed the assump­tion that the outbreak of the economic crisis in 2008 had a negative impact on the level and structure of household consumption expenditure, which was stronger in case of urban than rural households.
Multidimensional Scaling in Market Research: Advantages and Disadvantages
Authors: Kėdaitienė Angelė , Kėdaitis Vytautas 
Published: February 2020

Multidimensional scaling was developed by psychometricians, namely R. N. Shepard (1962) and J. B. Kruskal (1964). Its purpose is to deduce indirectly the dimensions a respondent uses to evaluate alterna­tives. The reason for using the indirect approach is that, in many cases, the attributes may be unknown and respondents may be unable or unwilling to repre­sent their reasons accurately. As already mentioned, multidimensional scaling requires an object-by-object similarity matrix as an input.
Initially popularized, however, multidimen­sional scaling relies on judged similarity. That is, re­spondents indicate how similar pairs of objects are directly rated (e.g. on a 1–10 scale). This can be a bur­densome task since for p objects p(p-1)/2judgments are needed. Still, the use of similarity judgments is relatively easy for respondents, especially when they cannot or do not want to reveal the basis for their opinion.
The results of multidimensional scaling depend on (a) the sample chosen to judge similarity and (b) the objects whose similarity is judged and the quality of input data. Multidimensional scaling derives dimen­sions that appear to be used by those rating a par­ticular set of objects.
The basic type of multidimensional scaling in­volves deducing graphical models of alternatives (e.g. brands) alone (simple space) from similarity data.
Some early applications of multidimensional scaling accepted apparent dimensions as “truth” without question or validation, which often proved to be disastrous. It is advisable to use multidimensional scaling as a generator of hypotheses rather than as a final model of the market. Any important result should be confirmed on a separate sample with a separate method, such as direct questioning, before the results are given too much credence.
Multidimensional scaling generates a configu­ration in which the relative positions of the brands are unique. The picture can be changed by several opera­tions without changing the relationship among the interpoint distance in some of the algorithms (as­suming the Euclidean distance is used, which it almost always is).
A major problem in data collection is the bur­den on respondents as the number of alternatives increases (e.g. 20 alternatives require 190 pairs). However, if respondents are “homogeneous”, it is possible to have different subjects rate a different pair.
Kernel Density Estimators for Gaussian Mixture Models
Authors: Ruzgas Tomas , Drulytė Indrė 
Published: February 2020

The problem of nonparametric estimation of probability density function is considered. The performance of kernel estimators based on various common kernels and a new kernel K (see (14)) with both fixed and adaptive smoothing bandwidth is compared in terms of the symmetric mean absolute percentage error using the Monte Carlo method. The kernel K is everywhere positive but has lighter tails than the Gaussian density. Gaussian mixture models from a collection introduced by Marron and Wand (1992) are taken for Monte Carlo simulations. The adaptive kernel method outperforms the smoothing with a fixed bandwidth in the majority of models. The kernel K shows better performance for Gaussian mixtures with considerably overlapping components and multiple peaks (double claw distribution).

Published: February 2020

Extending the research started in [31], the paper uses econometric methods for the short-term forecasting of quarterly values of sector indexes of stock prices from the OMX Baltic stock exchange. The ARMA models and modelling methodology that was used to build the statistical models in the previous paper are now augmented with the algorithms of time series aggregation and identification of special features of the series. Here, the search for informative factors relies on the study of related literature. The specification of models is further tailored using the traditional significance (p-value) analysis of regressors and a cross-validation analysis. The latter is implemented in this paper using the Jack-knife approach. The data period analysed covers the years 2000–2013. The results of the analysis indicate that the inclusion not only of recent autoregressive terms but also of some aggregated characteristics (as certain special features of indexes) improves the precision of forecasting substantially. The calculations were performed using the statistical analysis software SAS.

Published: February 2020

Background: Menarche is the most dramatic manifestation of puberty in girls; unlike the biometric developmental changes that occur at puberty, menarche requires the personal adjustment and response of an affected girl in order to attain good menstrual hygiene. This study was designed to evaluate how boarding secondary school girls manage their menstruation in school, away from the guidance of their parents.Methods: A cross sectional survey was performed in four public boarding secondary schools in the study area with the aid of structured questionnaires to evaluate how such girls manage their menstruation while in school.Results: The study population was 975 girls whose survey revealed the mean age at menarche of 12.5±1.4 years. Seven hundred and two (72.0%) respondents had received sexuality education before onset of menarche. Respondents who attained good menstrual hygiene were 775(79.5%). Such respondents were those who had received sexuality education (p<0.001) and those who had access to synthetic sanitary pad (p=0.005). Duration of the menstrual period and the volume of menstrual blood loss did not affect (p=0.219) the ability of respondents to attain good menstrual hygiene. Respondents who received sexuality education had about 605 chances of attaining good menstrual hygiene than those who did not receive such education.Conclusions: A vast majority of the respondents had received sexuality education before onset of menarche and a larger proportion attained good menstrual hygiene. Major factors that positively influenced the girls’ capacity to attained good menstrual hygiene were prior sexuality education and access to synthetic sanitary pad.
