The Relationship of the Tetrachoric Correlation Coefficient to the Phi Coefficient Estimated from the Extreme Tails of a Normal Distribution of Criterion Scores

В статье представлены материалы о взаимосвязи продолжительности продуктивного использования коров с характеристикой устойчивости к деградации, с возрастом отела и удоем. В исследованной, разнородной по происхождению, группе животных для прогноза продуктивного периода коров, обусловленного устойчивостью к деградации и возрастом первого отела, пригодно уравнение регрессии, аргументами в котором являются индекс устойчивости, возраст первого отела в первой и второй степенях. Коэффициент корреляции межу предсказанными значениями продуктивного периода и его фактическими величинами в I группе составляет 0,502, во II - 0,604. При этом крайние варианты прогнозируются со статистическими ошибками 5 мес при оценке индекса устойчивости по 2 лактациям и 4,1 мес по 3, а средние варианты, соответственно, 1,6 и 1,51 мес. Индекс устойчивости к процессу старения является важной характеристикой биологических особенностей коров, определяющий их продуктивное долголетие. Его оценка по первым 2 и 3 лактациям имеет прямолинейную связь с продуктивным периодом (r=0,4109 и r=0,5270), соответственно. Зависимость продуктивного периода от возраста первого отела криволинейная — с увеличением возраста первого отела сокращается срок продуктивного использования, при возрасте первого отела более 1400 дней срок продуктивного использования колеблется от 1,33 до 1,41 лактации. Коэффициент корреляции между этими характеристиками коров составляет - 0,2164 в I и - 0,2620 во II группах. The article presents materials about the relationship of the duration of productive use of cows with the characteristic of resistance to degradation, with the age of calving and milk yield. In the studied group of animals, which is heterogeneous in origin, the regression equation is suitable for predicting the productive period of cows due to resistance to degradation and the age of the first calving, the arguments of which are the stability index, the age of the first calving in the first and second degrees. The correlation coefficient between the predicted values of the productive period and its actual values in group I is 0.502, in group II - 0.604. At the same time, the extreme variants are predicted with statistical errors of 5 months when evaluating the stability index for 2 lactations and 4.1 months for 3, and the average variants, respectively, are 1.6 and 1.51 months. The index of resistance to the aging process is an important characteristic of the biological characteristics of cows, which determines their productive longevity. Its estimate for the first 2 and 3 lactations has a direct relationship with the productive period (r=0.4109 and r=0.5270), respectively. The dependence of the productive period age at first calving curvilinear with increasing age at first calving reduces the time to productive use, while age at first calving of more than 1400 days, the period of productive use ranges from 1.33 to 1.41 lactation. The correlation coefficient between these characteristics of cows is-0.2164 in I and-0.2620 in II groups.

Placental Thickness

Background: Knowledge of gestational age (GA) is important because it affects clinical management in many ways. Ultrasonography has provided a safe and noninvasive means of dating a pregnancy. The purpose of the present study is to assess the relationship of placental thickness with gestational age and to compare it with other sonographic parameters used to estimate gestational age. Subjects and Methods: The study included 242 normal pregnant women who knew their last menstrual period (LMP). After taking consent, all the women underwent an ultrasound examination. During the scan, besides measuring routine biometric parameters, Placental thickness at the cord insertion was also measured. A retrospective study was designated to test the hypothesis that placental thickness in an age dependant variable and hence can predict gestational age. In the end, the predicted gestational age by placental thickness was compared with gestational age as determined by other sonographic parameters. Results: Placental thickness showed a linear progression in relation to the menstrual age. The correlation coefficient was found to be 0.86(p<0.001). The regression equation was formulated by regressing gestational age on the measured placental thickness. The correlation coefficient between GA-LMP and GA-USG was 0.92 as compared to 0.86 between GA-LMP and GA-PT. The standard error for other USG parameters was +2.32 compared to +2.96 for placental thickness. Conclusion: Placental thickness being a fusion of menstrual age, can be used to predict the gestational age by using the regression formula. Gestational age calculated by other USG parameters is closer to menstrual age as compared to that by placental thickness. The prediction interval was slightly more when the placental thickness was used instead of other USG parameters. Placental thickness is a good alternative parameter for predicting gestational age in the second and third trimester.

THE RELATIONSHIP OF STUDENTS' UNDERSTANDING LEVEL OF ANIMAL MORPHOLOGY CHARACTERISTICS WITH THE ABILITY TO MEMORIZE ANIMAL LATIN NAMES IN GRADE 10 IPAAbstractAnimal taxonomy subjects often use animal's Latin names. Many students think that this subject is annoying because it is dominated by memorizing animal's Latin names, even though memorizing becomes a prerequisite for understanding. Meanwhile, most of the language materials memorized need an understanding before the memorizing process. This study aimed to find a relationship between the level of students' understanding of an animal's morphological characteristics and the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember. This study used a quantitative approach with a type of ex post facto. The test obtained the data. Then it was descriptively and inferentially analyzed by Kendall correlation. This research indicated that 56 students who answered test of the level of understanding animal's morphological characteristics and the ability to memorize animal's Latin names resulted in a correlation coefficient of score 0.673, and significance 0,000 < 0.05. Therefore, if the level of students’ understanding of an animal's morphological characteristics increased, the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember also increased, conversely. AbstrakNama latin hewan sering digunakan dalam materi taksonomi hewan. Banyak siswa beranggapan bahwa materi tersebut membosankan karena didominasi oleh menghafal nama latin hewan, padahal menghafal menjadi prasyarat pemahaman. Sementara itu, sebagian besar materi bahasa yang dihafal membutuhkan pemahaman sebelum proses menghafal berlangsung. Tujuan penelitian ini ialah mengetahui hubungan tingkat pemahaman karakteristik morfologi hewan dengan kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis eks post facto. Data didapatkan menggunakan instrumen tes. Kemudian dianalisis secara deskriptif dan inferensial menggunakan korelasi Kendall. Penelitian ini menunjukkan bahwa dari 56 siswa yang menjawab tes tingkat pemahaman karakteristik morfologi hewan dan kemampuan menghafal nama latin hewan menghasilkan koefisien korelasi 0,673 dan signifikansi 0,000 < 0,05. Dengan demikian, jika tingkat pemahaman karakteristik morfologi hewan meningkat, kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember juga meningkat, begitupula sebaliknya.

Abstract The way of the mother’s interaction with her child is called maternal interactive style. It has been studied in the context of shared reading. This study aimed to formulate a system of evaluation of the interactive style in shared reading through behavior categories. Categories were constructed from previous studies, and then empirically tested. Fifty-two dyads participated. The average age of the mothers was 35.70 (±6.13) years; the children’s ages varied from 22 to 76 months (Mean = 48.59; Standard Deviation = 17.88). The dyads were filmed in a shared reading interaction. The videos were then analyzed. Agreement analyses (intraclass correlation coefficient) were made between observers in order to test the categories. Most of the categories presented good or excellent agreement, indicating that they were well constructed and properly described. We believe that the system may be useful in future studies investigating the relationship of the maternal interactive style in shared reading with other variables involved.
