This e-book aims to present the most critical aspects of knowledge about using experiments in economics and practical tools for using them. The topic is extended to the more advanced and increasing in popularity area of biometric research. The book is divided into three parts mirroring experimentation. The first part provides theoretical background and tips about organising own research. The chapter is concluded with a guide focused on writing a research report in APA style. This part includes an example of the actual research report. The next part has two chapters, and both are guided tours allowing to plan and conduct eye-tracking research and electrodermal activity research (EDA). The chapters contain details about preparing experiments, conducting them, using the dedicated software to analyse collected data and interpreting the default charts. The last part is devoted to the data analysis and is universal, goes beyond the biometric experiments. There are three chapters in this part covering the standard procedures used in the analysis of experiments. The first part includes tests for one hypothesis: parametric t-test and One-Way ANOVA and non-parametric siblings: Mann Whitney U test and Kruskal-Wallis test. The next part describes tests allowing testing more hypotheses: ANOVA without repetition and ANOVA with repetitions. Furthermore, the last chapter deals with dependent samples, which are a popular approach in experiments. This part describes the dependent sample t-test and Wilcoxon test. The effect sizes calculations are included; each test is shown with screenshots from SPSS and some additional screenshots from Excel. This approach allows following the procedure step by step. The examples help easily understand procedures and interpretations; they were chosen from areas of sustainability and innovations to match the general idea of the e-books series prepared within the CENETSIE program. The book contains texts that can be useful in the teaching process. It can be helpful in graduate programs in economics and business schools. Programs of doctoral schools cab benefit from this book as well.

Scientific Reporting

The management activity of research report writing requires sufficient knowledge in its preparation. A researcher must learn about the management of understanding scientific concepts, as well as management of research reports that are based on scientific truth. In this study, 1 (one) method was used, namely a literature study of 10 (ten) to support the understanding of scientific concepts according to experts. The concept is a general idea that represents perceived understanding on the basis of reason and logic by someone who then forms a meaning deductively or inductively. Whereas knowledge is what is known or the results of work know. Then scientific truth is related to the quality of knowledge, where every knowledge possessed is viewed from the type of knowledge that is built. Thus scientific truth is an important point in scientific reporting, as the basic foundation of accurate management of report writing and must be displayed in every corner of the report. It is hoped that this research can assist researchers in compiling research reports. Keywords: Management, Science, Scientific Truth, Research Reports.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently.

The purpose of this study is to answer if there is a reasonable difference on academical success of students who get education with traditional and RME approach question on “Teaching geometrical objects to 8th grade students” subject. Study group consists of 47 students which contains 21 experimental and 16 control group from “Ordu Anadolu İmam Hatip High School Project School” in Altinordu, Ordu. Experimental and control group have same academical success level, as the school which this study has runned is a school which accepts students with an exam only. After the experimental and control groups were created, a 25 question pre-test was performed to understand the level of knowledge of the group regarding geometrical objects. The same test was performed on the same groups 8 weeks later as retention test. To determine opinions of the students in experimental group regarding RME and related learning activities, semi-structured interviews are conducted. The data obtained from the pretest, posttest and retention tests were analyzed with t-test for independent samples and t-test for dependent samples and variance analysis for mixed measurements with 0.05 significance level. According to the results, it is seen that learning activities prepared according to RME approach are much more effective than learning activities prepared according to the traditional approach on students’ academic success.

Parody as hybridic text: research report Parody can be seen as one of the techniques of selfreferentiality through which a consciousness of the context dependency of meaning is revealed in an aesthetic way. This article explores the theoretical background of parody as literary style against which the researcher challenged a group of teacher education students in a research programme to generate their own parodies. The task required that they choose a well-known fairy tale and use its structure to mock their own society. Students of another group were asked as the writers’ peers to read the stories in order to engage in a dialogue between encoder and decoder in the process of reception. The educational aim of the programme was to equip students to reflect critically and react creatively to social, political and economic issues that surround them. Furthermore, the researcher wanted to discover how these texts would generate a flexibility, fluency and hybridity in relationship with the students’ cultural identity and how they would project their own liminality in a no-man’s land between youth and adulthood. Analysis and interpretation of the parody texts revealed themes of late capitalism, materialism and consumerism, as well as typical student cultural manifestations of language usage and some of their existing attitudes toward the South African political society in post-apartheid. The students’ parodies have intertextual density with imitation and subversion of the original text contexts and values. The writers used a variety of stylistic techniques to generate double-voiced narratives as manifestation of literary creativity.

ABSTRACT Objective: This study evaluated alveolar bone loss around mandibular incisors, induced by the Herbst appliance. Methods: The sample consisted of 23 patients (11 men, 12 women; mean age of 15.76 ± 1.75 years), Class II, Division 1 malocclusion, treated with the Herbst appliance. CBCT scans were obtained before treatment (T0) and after Herbst treatment (T1). Vertical alveolar bone level and alveolar bone thickness of mandibular incisors were assessed. Buccal (B), lingual (L) and total (T) bone thicknesses were assessed at crestal (1), midroot (2) and apical (3) levels of mandibular incisors. Student's t-test and Wilcoxon t-test were used to compare dependent samples in parametric and nonparametric cases, respectively. Pearson's and Spearman's rank correlation analyses were performed to determine the relationship of changes in alveolar bone thickness. Results were considered at a significance level of 5%. Results: Mandibular incisors showed no statistical significance for vertical alveolar bone level. Alveolar bone thickness of mandibular incisors significantly reduced after treatment at B1, B2, B3, T1 and significantly increased at L2. The magnitude of the statistically significant changes was less than 0.2 mm. The changes in alveolar bone thickness showed no statistical significance with incisor inclination degree. Conclusions: CBCT scans showed an association between the Herbst appliance and alveolar bone loss on the buccal surface of mandibular incisors; however, without clinical significance.

Background: Dysfunctional uterine bleeding (DUB) is the most common menstrual disorder of women in any age group and is a diagnosis of exclusion. Medical management of menorrhagia is a difficult task as there are wide variations in the available drugs and a lot of different regimes are available. Present study evaluates efficacy and safety of ormeloxifene a selective estrogen receptor modulator (SERMs) as compared to combined oral contraceptive pills in treatment of dysfunctional uterine bleeding in perimenopausal women.Methods: Total 60 patients meeting with our inclusion and exclusion criteria were enrolled in the study over a time period of 6 months and were further divided randomly into two groups. One group was given Ormeloxifene and the other group was treated with combined oral contraceptive pills (COCP) over a period of six months. The outcome variables noted were pictorial blood loss assessment chart (PBAC) score, Hb level and combined endometrial thickness (CET). Quantitative variables were compared using independent t test/Mann-Whitney test between the two groups and paired t Test/Wilcoxon test was used for comparison between pre and post within the group.Results: Both ormeloxifene and COCP significantly reduce blood loss in these patients evidenced by decrease of PBAC score, rise in hemoglobin levels and decrease in CET levels. However, ormeloxifene was found to be superior to COCP in reducing the menstrual blood loss. Ormeloxifene was also tolerated better compared to COCP with fewer side effects experienced by patients.

Abstrak Terapi komplementer merupakan salah satu alternatif untuk mengatasi masalah kesehatan. Hidroterapi dan relaksasi Benson merupakan terapi komplementer yang efektif terhadap tekanan darah dan nadi, namun masih jarang masyarakat yang memanfaatkannya. Diketahui ada pengaruh kombinasi hidroterapi dan relaksasi Benson (disebut hidroson) terhadap tekanan darah dan nadi. Metode penelitian pra-eksperimen, pre- and post- design dengan teknik purposive sampel pada 32 responden usia 26-65 tahun. Penelitian dilakukan dari tanggal 1-18 Maret 2019 di RT 19 dan 20, Sungapan V Desa Wahyuharjo, Kecamatan Lendah, Kabupaten Kulon Progo dengan tiap responden diberikan intervensi selama 3 hari berturut-turut. Instrumen yang digunakan adalah sphygmomanometer digital untuk mengukur tekanan darah dan nadi 5 menit sebelum dan sesudah pemberian terapi. Tekanan darah dianalisis dengan wilcoxon test dan paired t-test untuk nadi. Hasil analisis menunjukkan tekanan darah sistolik sebelum terapi sebesar 118,25 mmHg dan setelah terapi sebesar 111,00 mmHg, sehingga disimpulkan terjadi penurunan sebesar 7,25 mmHg dengan ρ Value 0,0001. Tekanan darah diastolik sebelum terapi sebesar 81,25 mmHg dan setelah terapi sebesar 78,75 mmHg, sehingga disimpulkan terjadi penurunan sebesar 2,50 mmHg dengan ρ value 0,002. Nadi sebelum terapi sebesar 82,30 x/menit dan setelah terapi sebesar 80,64 x/menit, sehingga disimpulkan terjadi penurunan sebesar 1,66 x/menit dengan ρ value 0,003. Ada pengaruh yang signifikan terhadap pemberian kombinasi hidroterapi dan relaksasi Benson (hidroson) terhadap penurunan tekanan darah dan nadi di RT 19 dan 20, Sungapan V. Kata kunci: hidroterapi, Relaksasi Benson, tekanan darah, nadi Abstract Complementary therapy is one alternative to solving health problems. Hydrotherapy and Benson's relaxation are effective complementary therapies for blood pressure and pulse, but still few patients utilize it. There is a known effect of hydrotherapy and Benson relaxation combination (called hydrosol) on blood pressure and pulse. The study method was pre-experimental with pre and post design with a purposive sampling technique on 32 respondents aged 26-65 years. The study was conducted from 1-18 March 2019 in neighborhood 19 and 20, Sungapan V, Wahyuharjo Village, Lendah District, Kulon Progo. Regency Each respondent was given intervention with hydrosol therapy for 3 consecutive days. The instrument used was a digital sphygmomanometer to measure blood pressure and pulse 5 minutes before and after the administration of therapy. Blood pressure was analyzed by the Wilcoxon test while pulsing by paired t-test. The analysis showed that systolic blood pressure before therapy was 118.25 mmHg and after therapy became 111,00 mmHg, so there was a decrease of 7,25 mmHg with a p-value of 0,0001. The diastolic blood pressure before treatment was 81,25 mmHg and after therapy became 78,75 mmHg, so there was a decrease of 2,50 mmHg with a p-value of 0,002 mm. The pulse before therapy was 82,30 x / min and after therapy became 80,64 x / min, so there was a decrease of 1,66 x / min with ρ-value 0,003. There is a significant effect of giving a combination of hydrotherapy and Benson relaxation (hydrosol) on reducing blood pressure and pulse among 32 subjects in neighborhood 19 and 20, Sungapan V.
