In this note, I study how the precision of a binary classifier depends on the ratio r of positive to negative cases in the test set, as well as the classifier's true and false-positive rates. This relationship allows prediction of how the precision-recall curve will change with r, which seems not to be well known. It also allows prediction of how Fβ and the precision gain and recall gain measures of Flach and Kull (2015) vary with r.

ABSTRACT Objectives: To determine the relative effects of Herbst appliance therapy in hypo- and hyperdivergent patients. Materials and Methods: The treated group included 45 growing Class II, division 1, patients treated with stainless steel crown Herbst appliances, followed by fixed edgewise appliances. The untreated control group consisted of 45 Class II, division 1, subjects, matched to the treated sample based on Angle classification, age, sex, and pretreatment mandibular plane angle (MPA). Subjects were categorized as hypo- or hyperdivergent based on their MPAs. Pre- and posttreatment cephalograms were traced and superimposed on cranial base and mandibular structures. Results: The primary effect of the Herbst in terms of maxillomandibular correction was in the maxilla. It significantly restricted maxillary growth, producing a “headgear effect.” Mandibular treatment changes depended on divergence. Hyperdivergent patients experienced a deleterious backward true mandibular rotation with Herbst treatment. Hypodivergent patients, as well as untreated hypo- and hyperdivergent controls, underwent forward true mandibular rotation. However, hypodivergent chins did not advance any more than expected for untreated hypodivergent Class II patients. Conclusions: Hypo- and hyperdivergent patients benefit from the Herbst's headgear effect. While the mandibular growth of hypodivergent patients overcomes the negative rotational effects, hyperdivergent patients undergo a deleterious backward mandibular rotation and increases in facial height.

The objective of the present work was to evaluate the effect of somatic cell score on the longevity of Holstein cows raised all over Brazil, using a piecewise Weibull proportional-hazard model. The following two longevity traits were defined: true longevity, number of days from first calving to culling; and functional longevity, approximated by correcting true longevity to within-herd-year production. Records on productive life of 131330 cows were used. The model included the time-independent effect of age at first calving. The other effects were time-dependent, and included the following: region by year of calving, variation in herd-size class, milk-production class by year of calving within herd, within-herd milk-production class by number of lactations, within-herd fat content, within-herd protein content, and somatic cell score (SCS). The overall mean of the somatic cell counts (SCC) was 322000 cells/mL. The highest SCC mean was found between 130 to 290 days of lactation. The SCC mean decreased over the years. Cows from Region 5 (Rio Grande do Sul) showed higher SCC means. The risk of culling was slightly higher for functional longevity than for true longevity. The impact of longevity was high in cows from first to fourth lactation with a high SCS, with the risk of culling varying from 0.90 (true longevity: second lactation and Class 2) to 1.2 (functional longevity: fourth lactation and Class 5). Cows at the fifth lactation with a lower SCS had a higher risk of culling (1.4). Including the effect of SCS class by stage of lactation in the models was not beneficial. The decrease in SCS, especially from the first to fourth lactation, can be used for indirect selection to improve the longevity of Holstein cows in Brazil.

Streszczenie:

Class imbalance is a condition where the amount of data in the minority class is smaller than that of the majority class. The impact of the class imbalance in the dataset is the occurrence of minority class misclassification, so it can affect classification performance. Various approaches have been taken to deal with the problem of class imbalances such as the data level approach, algorithmic level approach, and cost-sensitive learning. At the data level, one of the methods used is to apply the sampling method. In this study, the ADASYN, SMOTE, and SMOTE-ENN sampling methods were used to deal with the problem of class imbalance combined with the AdaBoost, K-Nearest Neighbor, and Random Forest classification algorithms. The purpose of this study was to determine the effect of handling class imbalances on the dataset on classification performance. The tests were carried out on five datasets and based on the results of the classification the integration of the ADASYN and Random Forest methods gave better results compared to other model schemes. The criteria used to evaluate include accuracy, precision, true positive rate, true negative rate, and g-mean score. The results of the classification of the integration of the ADASYN and Random Forest methods gave 5% to 10% better than other models.

243 Background: Androgen deprivation therapy (ADT) is commonly prescribed for advanced prostate cancer (PCa) patients, but ADT has many side effects that can impair patients’ quality of life. In various Canadian cities, we are running an educational program to help PCa patients and their partners deal with the side effects of ADT, and maintain a strong relationship with each other while on ADT. Methods: Patients, who are about to start or have been on ADT, and their partners are invited to attend an educational program. Each patient is given a copy of the book Androgen Deprivation Therapy: An essential guide for men with prostate cancer and their partners (Wassersug et al., 2014) and attends a 1.5 hour educational class, where they learn strategies for managing ADT side effects and how to effectively make healthier lifestyle changes using goal-setting exercises. At the end of the class, participants are given the option to attend a monthly follow-up session. To evaluate the effectiveness of the program, participants are asked to complete questionnaire package before attending the class and again 2-3 months later. Results: As of August 2015, 179 patients and 113 partners have attended the ADT Educational Program at Victoria, Vancouver, and Calgary. About 40% of patients returned for the follow-up session. 62 attendees participated in the research evaluation portion of the program. Uniquely designed for this study, the questionnaire package assesses ADT side effect frequency, bother associated with side effects, use of management strategies, and self-efficacy regarding side effect management. An assessment of physical activity and relationship adjustment, and feedback about the class are also included. Conclusions: Patients and partners appreciate being informed about ADT side effects managements and how to make healthier lifestyle changes while on ADT. It remains to be seen how effective the program is in limiting the bother from ADT side effects and helping couples maintain a strong dyadic relationship in the fact of the challenges brought on by ADT. Good enrollment in the in-person program in the 3 cities has propelled the development of the program in Halifax and Toronto starting in fall 2015, and an online version to be available in early 2016.

Streszczenie:

It is well known that efficient estimation of average treatment effects can be obtained by the method of inverse propensity score weighting, using the estimated propensity score, even when the true one is known. When the true propensity score is unknown but parametric, it is conjectured from the literature that we still need nonparametric propensity score estimation to achieve the efficiency. We formalize this argument and further identify the source of the efficiency loss arising from parametric estimation of the propensity score. We also provide an intuition of why this overfitting is necessary. Our finding suggests that, even when we know that the true propensity score belongs to a parametric class, we still need to estimate the propensity score by a nonparametric method in applications.

AbstractThe aim of the submitted work is to study the influence of applied loads ranging from 0.09807 N to 0.9807 N on measured values of micro-hardness of heat treated aluminum alloy 6082. The influence of applied load on a measured value of micro-hardness was evaluated by Meyer’s index n, PSR method and by Analysis of Variance (ANOVA). The influence of the load on the measured value of micro-hardness is statistically significant and the relationship between the applied load and micro-hardness manifests the moderate reverse ISE. As the temperature of the solution treatment rises, the YS/UTS ratio and also Meyer’s index n, measured and “true hardness“ increase. On the other hand, its effect on the plastic properties of the alloy is ambiguous.

Abstract Ever since the discovery of the HLA-DOA and HLA-DOB genes in the HLA Class II region, controversy has surrounded their true function. Studies resulting in transcriptional modification of the HLA-DO gene analogs in mice (H-2O) support the general theory that DO decreases the presentation of antigens through the MHC class II system by inhibiting the effects of the MHC class II accessory molecule HLA-DM. The mechanism of such inhibition, however, still remains a mystery. To shed some light on this issue, we have constructed a recombinant form of soluble HLA-DO, without its cytoplasmic anchors, and conducted peptide binding experiments with soluble forms of recombinant HLA-DM and HLA-DR1. Our experiments indicate that DO can have both a negative and a positive effect on peptide presentation by the MHC Class II molecule HLA-DR1, depending on the quality of the anchoring residues of the peptide. In addition, HLA-DO only affects peptide association to the MHC Class II molecules and has virtually no effect on peptide dissociation.

In this comparative study, an attempt was made to examine the effects of two types of listening questions and activities on the quantity of note taking of intermediate EFL learners. In so doing, the researchers selected a sample of 30 intermediate English language learners randomly assigned to two comparison groups—Multiple-choice Group and True-false Group. The instrument for data collection was note taking papers of students from which the total number of words for each language learner was calculated. Results showed that the True-false Group gained higher scores in note taking quantity as compared with Multiple-choice Group. Based on the results of this study, it is imperative that EFL teachers pay serious attention to the types of activities and questions used in class as they can have an influence on the ways foreign language learners use note taking as a learning strategy.

Abstract True function of HLA-DO (DO), an MHC Class II accessory molecule remains a mystery. The leading model on it function proposes that DO inhibits the effects of DM. Most of those studies were have used in vivo mouse models, looking at the endpoint of peptide presentation, not taking into account the individual steps in the process. To directly study DO function, we designed a recombinant soluble DO that included leucine zipper for better dimerization of the DOα- and β- chains and expressed it in insect cells. Kinetic experiments involving DR1 and the peptide with or without DM and DO revealed unexpected results. We found that; a) DO diminishes the binding of two peptides that are DM-sensitive, b)DO has positive effects on binding of peptides that form DM-resistant complexes, c) DO only has an effect on peptide association and virtually no effect on peptide dissociation, and d) DO functionsdirectly on DR molecules.We propose that DO binds to the peptide-receptive MHC II molecules that DM generates either by dissociating the bound peptides, or opening of the empty groove. The role for DO then is to enforce another layer of control on peptide selection. In support of this hypothesis, using BIACore Surface Plasmon Resonance, we have measured direct binding of DO to an open conformation of HLA-DR1 in real time, while no binding to a closed DR1 conformation wasdetected.

Streszczenie:

Accordion performance is an emotional art, and the generation of emotions is inseparable from human psychological activities. It has a great relationship with the performance of music and has a great impact on the performance of the performance. The performance of the accordion is a process of psychological perception, understanding, imagination, experience, and emotion. It not only shows the true creative intention and emotion of the “original work” but also integrates it into the individual characteristics of the individual. In the creation, the true artistic vitality is given to each note, thereby enriching the musical composition, thus showing its unique charm. Therefore, this paper proposes a study on the emotional expression and playing psychology of accordion playing. In the end, the performance of class A students was significantly better than that of class B students, while more students in class B scored within 50-60 points, more students in class A scored within 90-100 points, therefore, the contrast is large. The average score of class A students is 80.125, and the average score of class B students is 71.45. The highest score for A can be as high as 98, the lowest score is 58, and the lowest score in class B is 51. It can be seen that having a high performance psychological quality and the ability to express emotions can achieve a good effect on accordion performance.

In continuation of studies on the effect of seed size on growth, made under part-I, the effect of seed size and seedling size are studied jointly by size-grading of seedlings in to three classes under each seed-size class, with 2700 F1 promising genotypes of two crosses. The combined population was screened in two steps, adopting comparison tree method. In step-1, transplanted seedlings (transplants) with closer spacing were screened based on shoot weight for a period of two crops and 487 genotypes were shortlisted based on higher superiority percent. In step-2, these 487 transplants were replanted with wider spacing and screened using three parameters for a period of four crops. In each crop, the genotypes which showed superiority percent value more than Minimum Selection Standard for the parameters studied, were shortlisted. Among 22 genotypes shortlisted finally, 18 have come from large seed-size class and the remaining four are also from long seedling-size class of medium seed-size class. This clearly established the importance of size-grading of seeds and seedlings in screening process. As the chance of getting any promising genotype from small seeds is remote they could be rejected before sowing and as it is also true with small seedlings they could be rejected at nursery stage screening. The tracking of juvenile performance of shortlisted genotypes indicated that, shoot length and root collar diameter are more reliable parameters for assessing the growth of seedlings at nursery. Comparison tree method is found to be highly useful for shortlisting of transplants in mulberry

Flipped classroom is a hybrid educational format that shifts guided teaching out of class, thus allowing class time for student-centered learning. Although this innovative teaching format is gaining attention, there is limited evidence on the effectiveness of flipped teaching on student performance. We compared student performance and student attitudes toward flipped teaching with that of traditional lectures using a partial flipped study design. Flipped teaching expected students to have completed preclass material, such as assigned reading, instructor-prepared lecture video(s), and PowerPoint slides. In-class activities included the review of difficult topics, a modified team-based learning (TBL) session, and an individual assessment. In the unflipped teaching format, students were given PowerPoint slides and reading assignment before their scheduled lectures. The class time consisted of podium-style lecture, which was captured in real time and was made available for students to use as needed. Comparison of student performance between flipped and unflipped teaching showed that flipped teaching improved student performance by 17.5%. This was true of students in both the upper and lower half of the class. A survey conducted during this study indicated that 65% of the students changed the way they normally studied, and 69% of the students believed that they were more prepared for class with flipped learning than in the unflipped class. These findings suggest that flipped teaching, combined with TBL, is more effective than the traditional lecture.

The flipped learning is a widely-used teaching method that increases the interaction between the instructor and the students by changing the in-class instructional time and the out-of-class practices. In this method, if students come to the class without studying the pre-course materials, this might lead to failures in its application. Besides, the gamified flipped learning environment was obtained by integrating the gamification elements in the pre-class phase of the flipped learning. The effects of teaching in this environment on students’ online behaviors and achievements were investigated. The participants were fourth-year undergraduate petroleum and natural gas engineering students enrolled in a natural gas engineering course. A true-experimental design was used in the study. Data were collected from a natural gas concept test, weekly quizzes, and data logs from Moodle. The research results indicated that teaching in the gamified flipped learning method showed a significant increase in the students’ participation in the pre-class activities of the flipped learning compared to the control group. Moreover, there was a significant increase in the achievement levels of the experimental group as compared to the control group. Based on these findings, the use of gamification elements in the pre-class phase of the flipped learning method can have a positive effect on the pre-course online behavior engagements of students. Furthermore, it was determined that it has a positive effect on the achievements of students who completed the method.

AbstractQuantifying true patterns of biodiversity change over the Cenozoic has major implications for all of biology and paleontology but is still a source of significant debate. The problem centers on the magnitude and nature of several well-known sampling effects and analytical biases in the fossil record, including the Pull of the Recent. We test the effect of the Pull of the Recent at both generic and species levels on the exemplary New Zealand Cenozoic marine mollusk fossil record. We examine several biological traits of species to determine whether particular attributes of taxa control their likely presence or absence in the youngest fossil record (<2.4 Ma). We demonstrate that, for a tectonically active region, the Pull of the Recent does not exert a strong effect on apparent diversity patterns of genera and species over the Cenozoic at temporal scales typically used in global and regional biodiversity analyses. This result agrees with previous studies quantifying the effect of the Pull of the Recent in the marine and terrestrial realms at the genus level. The effect of the Pull of the Recent, although small, is greatest for the youngest fossil record (<2.4 Ma), particularly for species. This increase cannot easily be explained by effects related to shell mineralogical composition, size, habitat, taxonomic class, or lithification. The small effect that the Pull of the Recent exerts on the New Zealand molluscan fossil record implies that the apparent rise in regional marine diversity during the Cenozoic represents a true biological signal and/or reflects other confounding effects not considered here.

When speakers share two or more languages in common, they often switch their languages in a conversation. It is true in the classes where both teachers and students must use a certain language as the language of instructions, as happening in the English classes of Computer Science students in Indonesia. Some teachers tend to always use English all the time with some considerations, whereas others often practice code-switching in the instructional process with other reasons, as well. This study is an observation of the effect of code switching to engage students in two English for computer science classes, in which the teacher in one class used code-switching and the other did not.DOI: doi.org/10.24071/ijiet.2019.030206
