Item response theory modeling for microarray gene expression data
Authors: Kastrin Andrej
Published: December 2021

The high dimensionality of global gene expression profiles, where number of variables (genes) is very large compared to the number of observations (samples), presents challenges that affect generalizability and applicability of microarray analysis. Latent variable modeling offers a promising approach to deal with high-dimensional microarray data. The latent variable model is based on a few latent variables that capture most of the gene expression information. Here, we describe how to accomplish a reduction in dimension by a latent variable methodology, which can greatly reduce the number of features used to characterize microarray data. We propose a general latent variable framework for prediction of predefined classes of samples using gene expression profiles from microarray experiments. The framework consists of (i) selection of smaller number of genes that are most differentially expressed between samples, (ii) dimension reduction using hierarchical clustering, where each cluster partition is identified as latent variable, (iii) discretization of gene expression matrix, (iv) fitting the Rasch item response model for genes in each cluster partition to estimate the expression of latent variable, and (v) construction of prediction model with latent variables as covariates to study the relationship between latent variables and phenotype. Two different microarray data sets are used to illustrate a general framework of the approach. We show that the predictive performance of our method is comparable to the current best approach based on an all-gene space. The method is general and can be applied to the other high-dimensional data problems.
Statistically sound distribution plots in Excel
Authors: Vidmar Gaj
Published: December 2021

Excel is the most widespread and the most powerful general-purpose spreadsheet software, but it is not popular with statisticians. Nevertheless, as a natural means for organising, displaying and analysing large amounts of data, spreadsheets keep gaining importance in statistical education and practice. Aiming at improving such practice rather than fruitlessly and indiscriminately condemning it, the paper provides general considerations on the topic, pointers to the huge body of relevant literature and software, and several concrete examples of data visualisation in Excel in the sense of univariate, bivariate and multivariate distribution plotting. Original and improved Excel solutions for producing dot-density plots, dot plots, stem-and-leaf plots, windowgrams, coplots and parallel coordinates plots are presented, as well as for performing the Box-Cox transformation. Additionally, further possibilities opening with the forthcoming Excel 2007 version, use of various commercial and freeware add-ins, and integration of Excel with statistical software are discussed.
On covariance estimation when nonrespondents are subsampled
Authors: Gamrot Wojciech
Published: December 2021

The phenomenon of nonresponse in a sample survey reduces the precision of parameter estimates and introduces the bias. Several procedures have been developed to compensate for these effects. An important technique is the two-phase (or double) sampling scheme which relies on subsampling the nonrespondents and re-approaching them in order to obtain the missing data. This paper focuses on the application of double sampling to estimate the finite population covariance. Two covariance estimators using combined data from the initial sample and the subsample are considered. Their properties are derived. Two special cases of the general procedure are discussed.
Topics in data analysis using R in extreme value theory
Authors: Penalva Helena , Neves Manuela
Published: December 2021

The statistical Extreme Value Theory has grown gradually from the beginning of the 20th century. Its unquestionable importance in applications was definitely recognized after Gumbel's book in 1958, Statistics of Extremes. Nowadays there is a wide number of applied sciences where extreme value statistics are largely used. So, accurately modeling extreme events has become more and more important and the analysis requires tools that must be simple to use but also should consider complex statistical models in order to produce valid inferences. To deal with accurate, friendly, free and open-source software is of great value for practitioners and researchers. This paper presents a review of the main steps for initializing a data analysis of extreme values in R environment. Some well documented packages are briefly described and two data sets will be considered for illustrating the use of some functions.
Choosing the number of factors in independent factor analysis model
Authors: Viroli Cinzia
Published: December 2021

Independent Factor Analysis (IFA) has recently been proposed in the signal processing literature as a way to model a set of observed variables through linear combinations of hidden independent ones plus a noise term. Despite the peculiarity of its origin the method can be framed within the latent variable model domain and some parallels with the ordinary factor analysis can be drawn. If no prior information on the latent structure is available a relevant issue concerns the correct specification of the model. In this work some methods to detect the number of significant latent variables are investigated. Moreover, since the method defines a probability density function for the latent variables by mixtures of gaussians, the correct number of mixture components must also be determined. This issue will be treated according to two main approaches. The first one amounts to carry out a likelihood ratio test. The other one is based on a penalized form of the likelihood, that leads to the so called information criteria. Some simulations and empirical results on real data sets are finally presented.

Authors: Zigon Giulia , Rosato Rosalba , Bò Simona , Gregori Dario
Published: December 2021

Objective: To compare some survival models as applied to the estimation of the costs of hospitalization as a function of several covariates in diabetic patients. The application of the Aalen regression model (Aalen, 1989) to medical costs is stressed. Design: Retrospective observational study analyzing hospitalizations in a cohort of diabetic patients with a follow up of 4.5 years. Study population: A total of 2550 patients have been included in the cohort, according to clinical-based enrollment standards. The patients with at least one hospitalization have been considered in this analysis. Methods: Costs have been modelled using five different regression model: the ordinary least square regression model, the logistic regression model using the median and the third quartile of the costs distribution as cut-off points, the parametric survival model assuming Weibull distribution, the Cox proportional hazard model and the Aalen additive regression model. Conclusions: The Aalen additive regression model applied to the costs has the best performances in estimating the mean hospitalization costs for specific clinical profiles.
scaling problems in service quality evaluation
Authors: Gallo Michele
Published: December 2021

In service quality evaluation we have to treat data having different kinds of scales. In order to obtain a measure of the service quality level a conventional ordinal rating scale for each attribute of a service is used. Moreover additional information on the customers or on the objective characteristics of the service is available (interval, ordinal and or categorical scale). In the latter the importance or weight assigned to the different items must be also considered (compositional scale). To analyze these different kinds of data particular precaution should be used, a transformation of quality level perceived (expected) data in quantitative scale is carried out before a multidimensional data analysis. In literature more techniques are proposed for the quantification of ordinal data preserving the original characteristics. The aims of this paper are to analyze different ways to quantify ordinal data, and illustrate how the additional information on the customers or on the service could be used in the multidimensional analysis as external information.
Pretest shrinkage estimators for the shape parameter of a Pareto model using prior point knowledge and record observations
Authors: Barmoodeh Leila , Qomi Mehran Naghizadeh
Published: December 2021

Considering a Pareto model with unknown shape and scale parameters α and β, respectively, we are interested in Thompson shrinkage test estimation for the shape parameter α under the Squared Log Error Loss (SLEL) function. We find a risk-unbiased estimator for α and compute its risk under the SLEL. According to Thompson (1986), we construct the pretest shrinkage (PTS) estimators for α with the help of a point guess value α0 and record observations. We investigate the risk-bias of these estimators and compute their risks numerically. A comparison is performed between the PTS estimators and a risk-unbiased estimator. A numerical example is presented for illustrative and comparative purposes. We end the paper by discussion and concluding remarks.

Confidence interval for the process capability index based on the bootstrap-t confidence interval for the standard deviation
Authors: Panichkitkosolkul Wararit
Published: December 2021

This paper proposes a confidence interval for the process capability index based on the bootstrap-t confidence interval for the standard deviation. A Monte Carlo simulation study was conducted to compare the performance of the proposed confidence interval with the existing confidence interval based on the confidence interval for the standard deviation. Simulation results show that the proposed confidence interval performs well in terms of coverage probability in case of more skewed distributions. On the other hand, the existing confidence interval has a coverage probability close to the nominal level for symmetrical or less skewed distributions. The code to estimate the confidence interval in R language is provided.

Authors: TEMÜR Cüneyt , GÜNEY Mehtap , ERDOĞAN Sibel , DEMİREL Murat
Published: December 2021

This experiment was conducted to determine the fermentation characteristics and in vivo digestibilities of silages prepared from soybean, sunflower and soybean-sunflower mixtures at different levels (15% soybean + 85% sunflower, 30% soybean + 70% sunflower, 45% soybean + 55% sunflower). For this purpose, a total of 25 silages, 5 for each mixture, were prepared in 120-liter drums. After 90 days of incubation, the content of crude materials, volatile fatty acids and fermentation characteristics of the silages were determined. To determine the digestive characteristics of the silages, 5 two-year-old Akkaraman rams with an average weight of 30-35 kg were used. The classical digestion method was used in the study. Dry matter (DM), organic matter (OM) and crude protein (CP) contents increased and ether extract (EE), acid and neutral detergent fiber (ADF and NDF) contents decreased with increasing soybean content in the mixtures. While the lowest pH, acetate, propionate and the highest Flieg values were determined in silages containing 30% soybean and 70% sunflower, the lowest butyrate value was determined in silages containing 15% soybean and 85% sunflower. The highest butyrate, lactate, EE, NDF and the lowest dry matter, CP contents were determined in sunflower silages. Digestibilities of DM, OM and CP were higher in soybean silages than others. While the highest EE digestibility was found in 30% soybean + 70% sunflower silage, the highest ADF content was found in 15% soybean + 85% sunflower silage and the lowest NDF content was found in sunflower silages. Consequently, sunflower and soybean silages and different mixture ratios did not lead to negative results and quality silages were obtained. According to fly evaluation, the best quality silages were obtained from a mixture of 30% soybean + 70% sunflower. Regarding digestibility, 100% soybean silage and 15% soybean silage + 85% sunflower silage had higher digestibility values than the others. It was concluded that these two silages can be recommended due to their higher digestibility.

Authors: Tekbaş-Atay Meltem , Büyükgöze-Dindar Mediha
Published: December 2021

Purpose: This study aimed to evaluate the patient’s knowledge, attitude, and practice of cross-infection control in dentistry. Materials & Methods: This cross-sectional study was conducted at the Faculty of Dentistry, Trakya University. In this study, 250 patients (134 female and 116 male) aged 18 years and older (35.5±13.9) participated and data were collected using a questionnaire containing questions to determine the knowledge, attitudes, and practices related to cross-infection and infection control. Required personal and socio-demographic data were obtained. A chi-square test was conducted for categorical variables. Kruskal Wallis and Mann-Whitney U tests were used to compare questionnaire scores (p <0.05).
Results: Most of the participants (30.5%) reported that their sources of information on dental infection control were social media. Knowledge scores of females were statistically significantly higher than males (p=0.005) and participants living in the city were significantly higher than those living in the town (p=0.015). Knowledge scores of health-care workers were significantly higher than both other workers and unemployed/students (p=0.001, p=0.004, respectively). Regarding participants’ attitudes and practices, only 29.2% of the participants questioned the dentists about the contagious disease, and only 36% asked about the sterilization method of the dental instruments. Most of the participants perceived that wearing gloves, masks, eyewear, and face shield would protect both patients and dentists.
Conclusion: Participants in this study seem to have a satisfactory level of knowledge about cross-infection and infection control methods in the nowadays’ pandemic condition. However, dental health professionals should make additional efforts to educate and encourage dental patients.

Published: December 2021

Young women have been found to experience body image dissatisfaction as a consequence of excessive social media usage and vice versa. Therefore, the current study was conducted to examine the relationship between body image dissatisfaction and social media use in young women aged 19-23 years in a Pakistani sample. A sample of 401 young women from different cities of Punjab province completed an online Google Form-based questionnaire containing informed consent, demographic sheet, and two scales namely social networking usage scale and socio-cultural attitude towards appearance questionnaire-4 (SATAQ-4). The findings of the study significantly predicted excessive social media usage from body dissatisfaction. The pressure sub scale of body image dissatisfaction was found to be significantly associated with social media usage. There were found no differences in body image dissatisfaction and social media usage in single and married young women. However, urban women were found to have high levels of body image dissatisfaction than rural women. The study concluded that body image dissatisfaction could lead to excessive social media usage in young women. The future directions and limitations of the study were discussed.
Non si può fermare il vento con le mani – Populismo e Moralismo nella crisi del pensiero europeo
Authors: Castiglioni Federico
Published: December 2021

One of the distinctive features of a democratic society is the pervasive and endless public debate that regularly antagonize groups and individuals, clashing different interests and ideologies. In this competitive environment, the delegitimization of a political enemy is the more natural – and yet democratically unhealthy – way to win the confrontation between diverse ideas. Historically, one of the predilected strategies to discredit a political adversary has always been blaming its morality, thereby eroding the very root on which any consensus rests. The moral blaming is declined differently, depending on the social and cultural context of the time and therefore the dominating values. In a democratic debate, these moral allegations often relate to duplicity or spreading of misinformation, the so-called demagogy. Today, the same campaign is rolled out against some partiers accused to be “populists” for their appeal to the most illogic and instinctive popular sentiment. The definition of “populism” is though still uncertain and subject to academic debate. This article aims at presenting different definition and interpretation of this political phenomenon to better frame it in the nowadays Western politics. The concept of populism is considered in its different shapes, questioning on the one hand the consistency of the existing definition and on the other its relationship with the democratic tenet. At the end of this analysis, the focus is shifted to the European Union and the reason as to why all the populist parties are seemingly Eurosceptic. The reason provided challenges the ideas of European unity itself, underlying the contrasting directions that the experiment of integration conveys, and question the multi-layered architecture of the contemporary democracy.

Business diplomacy ca instrument pentru implementarea intereselor economice externe ale Republicii Moldova
Authors:   Academia de Administrare Publică, Republica Moldova, Golovataia Ludmila
Published: December 2021

Problemele dezvoltării exportului de bunuri și servicii moldovenești, precum și creșterea competitivității internaționale sunt foarte relevante astăzi. Consolidarea poziției Republicii Moldova în economia mondială este o sarcină necesară și inevitabilă. Cu toate acestea, politica externă și factorii economici externi, cum ar fi presiunea corporațiilor multinaționale, creează dificultăți pentru companiile moldovenești de a-și apăra și promova interesele pe piețele externe. Subdezvoltarea sistemului intern de promovare a exporturilor, complexitatea mediului politic și economic internațional și numeroase riscuri actualizează necesitatea de a analiza și a considera conceptul de business-diplomație în cadrul diplomației economice ca un mecanism promițător pentru asigurarea intereselor industriei și companiilor individuale din țări străine. Ca subspecie a diplomației economice, business-diplomația este caracterizată ca o formă mai aplicată de realizare a intereselor economice, inclusiv metode de lobby și comunicare cu statul. Această formă de promovare a intereselor economice la nivel internațional, bazându-se pe structuri diplomatice și misiuni comerciale, poate facilita interacțiunea mai strânsă a companiilor interne atât cu agențiile guvernamentale străine, cât și cu departamentele moldovenești, pentru a realiza interese comerciale în străinătate. Articolul prezintă situația reală din domeniul diplomației economice în Republica Moldova și oferă câteva recomandări pentru îmbunătățirea acesteia.

Управление энергией часто сводится к задаче ее экономии. Однако управление энергопотреблением является более широкой концепцией. Оно включает планирование и управление операциями подразделений производства и потребления. Другими словами, управление энергией подразумевает под собой взаимосвязь между получением, распределением и использованием энергии для нужд человека с целью экономии средств и охраны окружающей среды. В связи с этим в июне 2011 года Международная организация по стандартизации выпустила стандарт ISO 50001: 2011 для систем управления энергией – требования и руководящие принципы. Стандарт предназначен для повышения энергоэффективности. Объектом исследования является энергетическая система университета, включающая административные и учебные корпуса, где размещены учебные аудитории и лаборатории, производственные помещения, мастерские.
Argumentation as a Speech Act: A (Provisional) Balance
Authors: Labinaz Paolo
Published: December 2021

This paper investigates whether, and if so, in what way, argumentation can be profitably described in speech-act theoretical terms. I suggest that the two theories of argumentation that are supposed to provide the most elaborate analysis of it in speech-act theoretical terms (namely van Eemeren and Rob Grootendorst’s Pragma-Dialectics and Lilian Bermejo-Luque’s linguistic normative model of argumentation) both suffer from the same two flaws: firstly, their “illocutionary act pluralism” assumption and secondly, a lack of interest in where arguing belongs in the classification of illocutionary acts. I argue that these flaws derive from the authors’ reliance on an intention-based speech-theoretical framework. Finally, I adopt a deontic framework for speech acts in order to propose an alternative way of accounting for argumentation which seems to overcome the two limitations outlined above. According to this framework, argumentation may be conceived as a speech act sequence, characterized by the conventional effects brought about by the communicative moves (as illocutionary acts) of which it is composed.
Governance, Real Output and Foreign Direct Investment in Asia: A Panel Data Analysis
Authors: Altaf Hussain  , Nawaz Muhammad Atif , Ibraheem Ruqayya
Published: December 2021

This study intends to analyze the impact of governance (such as political, economic and institutional governance) on real output (GDP) and foreign direct investment (FDI) in 26 Asian countries during 1996 – 2019. Results of panel ARDL show the positive impact of capital, labor and trade openness on GDP and FDI. Institutional governance affects GDP and as well as FDI negatively and validates the notion that corruption greases the wheel of growth but when institutional governance is used with other indicators of governance in the model, it affects the FDI positively. Other dimensions of governance such as political and economic governance have a positive and significant impact on GDP and FDI in all model specifications. The results of the panel causality test that there is bi-directional causality from governance to GDP but evidence of bi-directional causality among governance indicators have also been found. The study emphasized on the policy making to improve the level of governance in Asian countries.

GG25 en yaygın olarak kullanılan dökme demir alaşımıdır. Bu malzeme, yüksek sağlamlık ve aşınma direncine sahiptir ve ek ısıl işleme ihtiyaç duymaz. Bu nedenle üretim maliyetleri düşüktür. Ağırlıklı olarak perlitik yapıya sahip lamelli bir dökme demirdir. Sertlikleri 230 Brinell’e kadar çıkabilmektedir. Bu nedenle özellikle delme ve frezeleme işlemleri zordur. Bu çalışmada özel olarak döktürülmüş GG25 numunelerine yüzey frezeleme işlemi gerçekleştirilmiştir. Yüzey frezeleme işlemi için üç farklı kaplamaya sahip kesici uç (TiALN kaplamalı, TiN-TiCN-Al2O3 kaplamalı ve ALTiN kaplamalı), üç farklı kesme hızı (150, 200 ve 250 m/dak), üç farklı ilerleme (0.10, 0.25 ve 0.35 mm/diş) ve üç farklı kesme derinliği (0.5, 1 ve 1.5 mm) kesme parametresi olarak kullanılmıştır. Deneysel tasarım için Taguchi L27 (34) ortogonal dizisi seçilmiş ve 27 deney gerçekleştirilmiş, kesme parametreleri Taguchi metodu ile optimize edilmiştir.. Her bir deney esnasında kesme bölgesinden termal kamera ile sıcaklık ölçümleri yapılmıştır. Deneysel sonuçlar Varyans analizi ve üç boyutlu grafikler ile değerlendirilmiştir. Optimizayon sonucunda minimum sıcaklık için optimum parametreler, TiN-TiCN-Al2O3 kaplamalı kesici uç, 200 m/dak kesme hızı, 0.25 mm/diş ilerleme oranı ve 0.5 mm kesme derinliğidir. Varyans analizi değerlendirildiğinde sıcaklığa etki eden et etkili faktör kesme derinliği olmuştur. Taguchi optimiza parametreler ve üç boyutlu grafikler değerlendirildiğinde, minimum sıcaklık için en uygun kaplama türü TiN-TiCN-Al2O3 kaplamalı kesici uç olduğu görülmüştür.

أثر الاستخدام المتكامل للسماد الإحيائي و الكيميائي على إنتاجية الفول المصري (Vicia faba L.)‎ في السودان

أجريت ثلاثة تجارب حقلية في موسم 2007 / 2008م في المزارع التجريبية لهيئة البحوث الزراعية في كل من منطقة دنقلا و الحديبة و شندي لدراسة أثر استخدام أسمدة إحيائية (بكتيريا الرايزوبيم-سلالةENRRI 9 و / أو البكتيريا المذيبة للفسفور-الفسفوباكترين) و كيميائية (يوريا 46% N+ فوسفور 48% P2O5) منفردة و متكاملة على إنتاجية محصول الفول المصري (الصنف حديبة72 ).

تم ترتيب المعاملات حسب تصميم القطاعات الكاملة العشوائية في أربع مكررات.

توصلت النتائج إلى أن التسميد ببكتريا الرايزوبيم منفردة أو متكاملة مع الفسفوباكترين أدى إلى زيادة معنوية في متوسط إنتاجية الفول المصري مقارنة بالشاهد لمنطقة دنقلا، في حين أن التسميد بالفسفوباكترين لوحدة أدى إلى زيادة معنوية في متوسط الإنتاجية في كل من منطقتي دنقلا و الحديبة.

أوضحت النتائج أن التسميد الكيميائي بمفرده أدى إلى زيادة معنوية في متوسط إنتاجية الفول المصري مقارنة بالشاهد في منطقتي دنقلا و الحديبة.

أظهرت النتائج أن زراعة الفول المصري في المناطق الثلاث ذات عائد مجد اقتصاديا.

حيث أعطى التسميد المتكامل ببكتريا الرايزوبيم و الفسفوباكترين أعطي أعلى معدل ربح في منطقة دنقلا، أما في منطقة الحديبة كان أعلى معدل ربح عند التسميد ببكتريا الرايزوبيم، بينما في منطقة شندي كان أعلى معدل ربح عند التسميد المتكامل بالفسفوباكترين و السماد الكيميائي.

أشارت النتائج الى أن أعلى ربحية يمكن الحصول عليها عند استخدام الأسمدة الإحيائية الكيميائية.

Abstract. Evidence indicates that people not only mistakenly believe they are able to recognise risky situations in their everyday lives and avoid Sexually Transmitted Infections (STIs), but also that they hold stereotypical beliefs about who is most likely to contract an STI. In particular, if the image of a sexual partner is not consistent with the stereotypical image of someone who is infected with an STI, the possibility that the partner could be infected may be underestimated. Digital interventions offer enormous potential for young people’s sex education. This paper focuses on designing and developing interventions that could give people the potential to engage with the world and their sexual interactions on a different layer within which they can come to better understand the ramifications of the risk taking involved in their sexual behavior, via a safer setting. But what makes an effective sex education program? As early literature evidence suggests, a two-way, interactive, secure and tailored form of education is more promising than a traditional one-way passive from of education. A survey was conducted and the collected data was analysed to further elicit the user requirements of innovative digital sex education interventions. Keywords: sex education, digital interventions, sexual health, innovation.

This paper presents the data of comparative studies of the characteristics of the Mxus XF15R brushless elec-tric motor (rotation speed; consumed current, power and efficiency) depending on the maximum torque. The de-sign of the stand for studying the characteristics of the seeding process when using an electric drive of the seed-ing disc is presented; the key elements of the stand are: the seeding section, seeding disc, electric motor connect-ed to the seeding disc, the control unit, the source of rare-fied pressure, the seeding disc speed sensor and the seeding sensor. The technique of working with the stand and the procedure for setting it up are described. During the operation, the following indicators are taken into ac-count: control signal of the seeding disc drive; seeding disc and rotor revolutions, rpm; the number of the seed in the total volume from the moment of measurement; time between seeds falling, ms; vacuum, kPa; hole diameter, mm; reference time between the fall of adjacent seeds at a given rotational speed of the seeding disc, ms. During the experiment, it was found that with a value in the seed-ing chamber of 5 kPa, in the frequency range of the seed-ing disc from 17-100 rpm, the actual seeding rate was 3.28 pcs m, the number of twins in the seeding process was 8.17%, the number of gaps in the sowing process was 5.46%, and the deviation from the set rate was 5.2%. Thus, the electric drive of the seeding disc based on the brushless DC motor XF15R Mxus has shown its efficiency and may be used in the existing configuration of the MC type sowing device.

The search for the optimal variant of the structural ar-rangement of flat-screen separators by centrifugal-air sepa-rators with annular pneumatic separation ducts is a promis-ing direction in the development of new equipment. This will significantly improve the technological performance of grain cleaning plants. It may be considered a promising direction for such research. Therefore, it is necessary to look for new options for the layout of grain cleaning ma-chines to increase their technological efficiency. Several variants of technological schemes for the operation of ex-isting flat-sieve separators with a centrifugal-air separator with an annular pneumatic separation ducts are proposed. The technological process of the modernized grain clean-ing plant based on the A1-BIS-100 plantis described. The main parameters of the gravity transporting device are de-termined; they fully ensure the operability of the modern-ized plant.
