AbstractA good assignment of code reviewers can effectively utilize the intellectual resources, assure code quality and improve programmers’ skills in software development. However, little research on reviewer assignment of code review has been found. In this study, a code reviewer assignment model is created based on participants’ preference to reviewing assignment. With a constraint of the smallest size of a review group, the model is optimized to maximize review outcomes and avoid the negative impact of “mutual admiration society”. This study shows that the reviewer assignment strategies incorporating either the reviewers’ preferences or the authors’ preferences get much improvement than a random assignment. The strategy incorporating authors’ preference makes higher improvement than that incorporating reviewers’ preference. However, when the reviewers’ and authors’ preference matrixes are merged, the improvement becomes moderate. The study indicates that the majority of the participants have a strong wish to work with reviewers and authors having highest competence. If we want to satisfy the preference of both reviewers and authors at the same time, the overall improvement of learning outcomes may be not the best.

Assignment Model

This article examines the role of random sampling and random assignment in the interpretation of research results. Students and faculty were asked two multiple-choice questions about research methods. When questioned about the role of random sampling, 75% of all subjects correctly associated it with generality inference (generalizability). When asked about the role of random assignment, however, only 27% of all subjects correctly associated it with causal inference. The remaining subjects allocated at least some part of the role of random assignment to generalizability. We suggest that these findings reflect a bias in psychologists' training due to teaching a statistical model that stresses random sampling and generality inference. We discuss the random assignment model, which focuses on causal inference, and recommend that both models be taught in introductory methods and statistics courses.

Assignment Models

In this paper, an integrated simulation optimization model for the assignment problems is developed. An effective algorithm is developed to evaluate and analyze the back-end stored simulation results. This paper proposes simulation tool SIMASI (Simulation of assignment models) to simulate assignment models. SIMASI is a tool which simulates and computes the results of different assignment models. This tool is programmed in DOT.NET and is based on analytical approach to guide optimization strategy. Objective of this paper is to provide a user friendly simulation tool which gives optimized assignment model results. Simulation is carried out by providing the required values of matrix for resource and destination requirements and result is stored in the database for further comparison and study. Result is obtained in terms of the performance measurements of classical models of assignment system. This simulation tool is interfaced with an optimization procedure based on classical models of assignment system. The simulation results are obtained and analyzed rigorously with the help of numerical examples.

Breastfeeding Counseling

Background : Scaling Up Nutrition movement is a global effort to strengthen our commitment and accelerating action plan to improve nutrition, particularly the handling of nutrition in the first 1,000 days of life is exclusive breastfeeding and it until 24 months. One of the way is with exclusive breastfeeding counselling that can reduce stunting. The counseling is addressed to brides who need special attention in improving the nutrition and health. Objective : The aim of research to improve knowledge about exclusive breastfeeding counseling the bride through the use of leaflets. Method : This quasi-experimental study was a sample of 30 person a brides with non-random assignment, the variable a knowledge obtained through interviews using questionnaires while the method of counseling does face to face with an exclusive breastfeeding leaflet. The data was analyzed by dependent t-test. Result : The results showed exclusive breastfeeding counseling can improve knowledge bride (p= 0,000) with a mean difference is 6,13 and a deviation is 3,71. Conclusion : Increase of knowledge among ‘bride-to be’ about exclusive breastfeeding could be improved through the use of exclusive breastfeeding leaflet. Each health center must be in collaboration with Office of Religious Affairs to have exclusive breastfeeding counseling, and set one of the priority programs in the prevention of child stunting.   Keywords: Bride, counseling, knowledge of exclusive breastfeeding

Quasi Experiment

Penelitian ini bertujuan untuk: 1) mengetahui perbedaan hasil belajar antara mahasiswa yang diajarkan dengan Problem Based Learning dibanding mahasiswa yang diajarkan pembelajaran Group Investigation, 2) mengetahui peningkatan hasil belajar mahasiswa akibat penerapan pembelajaran Problem Based Learning. Jenis penelitian ini quasi experiment. Populasi penelitian adalah sebanyak 132 orang mahasiswa dilakukan secara random assignment. Teknik pengumpulan data menggunakan tes tertulis. Data yang diperoleh dianalisis dengan statistik deskriptif. Hasilnya sebagai berikut. 1) Terdapat perbedaan hasil belajar antara mahasiswa yang diajar Problem Based Learning dengan nilai rata-rata 75,00, nilai tertinggi 90 dan nilai terendah 55, dibandingkan mahasiswa yang diajar pembelajaran Group Investigation dengan nilai rata-rata 59,55, nilai tertinggi 75, dan nilai terendah 40. 2) Ada peningkatan hasil belajar mahasiswa akibat penerapan pembelajaran Problem Based Learning dengan nilai rata-rata peningkatan 46,11 dan ada peningkatan hasil belajar siswa dengan pembelajaran Group Investigation sebesar 29,20.
