The Difference

The traditional technique for converting repeating decimals to common fractions can be found in nearly every algebra textbook that has been published, as well as in many precalculus texts. However, students generally encounter repeating decimal numerals earlier than high school when they study rational numbers in prealgebra classes. Therefore, how do prealgebra students in the middle grades convert repeating decimals to fractions without using the age-old algebraic process (multiplying and finding the difference of two “stacked” equations) or without applying the precalculus approach of treating repeating decimal digits as an infinite geometric series?.

Abstract Background Tobacco use accounts for half the difference in life expectancy across groups of low and high socioeconomic status. The objective was to assess whether social inequalities in smoking in Canada-born young adults are also apparent among same-age immigrants, a group often viewed as disadvantaged and vulnerable to multiple health issues. Methods Data were drawn from the Interdisciplinary Study of Inequalities in Smoking, a longitudinal investigation of social inequalities in smoking in Montreal, Canada. The sample included 2,077 young adults age 18-25 (56.6% female; 18.9% immigrants). Immigrants had been in Canada 11.6 (SD 6.4) years on average. The association between level of education and current smoking was examined separately in immigrants and non-immigrants in multivariate logistic regression analyses controlling for covariates. Results Twenty percent of immigrants were current smokers compared to 24% of non-immigrants. In immigrants, relative to those who were university-educated, the adjusted odds ratio (OR) (95% confidence interval) for current smoking was 1.2 (0.6, 2.3) among those with pre-university or vocational training, and 1.5 (0.7, 2.9) among those with high school education only. In non-immigrants, the adjusted ORs were 1.9 (1.4, 2.5) among those with pre-university or vocational training and 4.0 (2.9, 5.5) among those with high school education. Conclusions Despite a mean of over 10 years in Canada, young adults who immigrated to Canada did not manifest the strong social gradient in smoking apparent in non-immigrants. Identification of factors that protect immigrants from manifesting marked social inequalities in smoking could inform the development of smoking preventive intervention sensitive to social inequalities in smoking. Key messages A social gradient in smoking apparent in Canada-born young adults was not observed in same-age immigrants. Factors that protect immigrants against social inequalities in smoking should be identified.

In solid geometry needed the ability to visualize space that cannot be seen so differences in visual intelligence can trigger errors in solving geometry problems. Therefore, this study aimed to determine the types of errors made by students and the factors that cause errors in working on geometry problems based on Newman's Error Analysis (NEA) in terms of visual intelligence. This research chose the subjects of class XII high school who had studied the material distance points to lines in space with different levels of visual intelligence, namely high and low. The process of collecting data used visual intelligence test questions, geometry test questions, and interviews. The results of this study indicated that the level of students' visual intelligence affects the difference in location and the factor that causes errors in the stage of transformation especially on determining the distance in dimension 3. Students with high visual intelligence made mistakes at the stage of transformation and encoding that caused by the students’ carelessness. However, students with low visual intelligence made mistakes at the stage of comprehension, transformation, process skills, and encoding due to the concept of the point distance to the line and the concept of the Pythagorean theorem.

Anak Pelangi Indonesia (API) Foundation is a non-profit foundation that offers scholarship programs for elementary, middle and high school students. This institute is supported by donaturs who give contribution to the Foundation. The donation is processed to be a cost that is used to pay Sumbangan Pembinaan Pendidikan (SPP) or Education Development Donation of each student. Currently, the provision of monthly donor fund is at uncertain amount so that the Foundation needs to determine the students of whom SPP will be firstly paid. However, the funding needs of each student are different due to the different amount of SPP and a giving fine from the school for the tardiness in paying the tuition. From these matters, the Foundation finds it difficult in deciding which students whose the tuition will be paid first. The solution to this problem is to use the four criteria referring to the tuition payment, namely the difference of pay date, fine, rank, and the amount of payment. The four criteria is then given the same integrity which is 25% for each criteria and counted by using Weighted Product (WP) method. The result of this research is an information system to the selection of scholarship payment using Weight Product method that takes the biggest value from the calculation result as a reference in deciding which students of whom SPP will be initially paid in accordance with the current fund condition.

The Difference

Based on the mandate of Law Number 23 Year 2014 on Local Government, the management and authority of high school (SMA) and vocational high school (SMK) in the district/city governments are taken over by the provincial governments. The handover began in March 2016, and must be completed in early 2017. BPK’s audit found a difference of asset value of about Rp26 billion during the handover process. This study aims to determine the process of asset transfer carried out by the district/city governments to the provincial government, problems and constraints faced as well as the accounting treatment of the transferred assets. This study uses a qualitative descriptive method with empirical data which are collected through observation, interviews and documentation. The asset transfer procedure start from the recording process of assets owned by the district/city education office. The asset record data is subsequently submitted by the district/city education office to the district/city regional financial and asset management agency (BPKAD). Furthermore, without prior confirmation and physical checking, these records were used as a basis for calculating the amount of assets to be handed over to the provincial BPKAD in October 2016.Total assets transferred was Rp1,738,599,434,341.84, and the difference in value found by the BPK was due to incomplete reporting of grants to SMA/SMK that was allocated from the APBN. Problems that are quite complicated are in school’s land ownership, inadequate quantity and quality of human resources, multiple asset recording, lack of complete reporting, and various other administrative and accounting problems.AbtrakBerdasarkan amanat Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintahan Daerah, pengelolaan dan kewenangan pendidikan Sekolah Menengah Atas (SMA) dan Sekolah Menengah Kejuruan (SMK) di pemerintah kabupaten/kota, diambil alih oleh pemerintah provinsi. Serah terima ini mulai dilaksanakan pada bulan Maret 2016, dan harus tuntas pada awal tahun 2017. Hasil audit BPK menemukan adanya selisih nilai aset sebesar Rp26 miliar dalam proses serah terima aset ini. Penelitian ini bertujuan untuk mengetahui proses pengalihan aset yang dilakukan oleh pemerintah kabupaten/kota dan provinsi, permasalahan dan kendala yang dihadapi serta perlakuan akuntansi terhadap aset yang dialihkan tersebut. Penelitian ini menggunakan metode deskriptif kualitatif dengan menggunakan data empiris yang dikumpulkan melalui observasi, wawancara dan dokumentasi. Proses ini dimulai dari data catatan aset yang dimiliki oleh dindikbud kabupaten/kota. Data tersebut diserahkan oleh dindikbud kabupaten/kota kepada BPKAD kabupaten/kota. Selanjutnya tanpa melakukan konfirmasi dan pengecekan fisik terlebih dahulu catatan tersebut dijadikan dasar untuk melakukan penghitungan jumlah aset yang akan diserahterimakan kepada pihak BPKAD provinsi pada bulan Oktober 2016. Nilai total aset yang dialihkan sebesar Rp1.738.599.434.341,84, selisih nilai yang ditemukan BPK disebabkan oleh tidak lengkapnya pelaporan hibah ke SMA/SMK yang bersumber dari APBN. Permasalahan yang cukup rumit terdapat pada kepemilikan tanah sekolah, kualitas dan kuantitas sumber daya manusia yang kurang memadai, pencatatan aset ganda, kurang lengkapnya pelaporan, serta berbagai permasalahan administratif dan akuntansi lainnya.

How do people feel emotions for someone else? This has been studied asempathy—feeling the same emotion that someone else feels. But people also feel emotions for someone else that the other person doesn’t feel, such as feeling angry for someone who is sad. We use appraisal theories to predict that people feel an emotion for someone else when they appraise that person’s situation differently. According to appraisal theories, people react to misfortunes with anger if they are caused by another person, but not if the cause is impersonal, and we predicted that this would also be true in feeling emotions for another person, regardless of what the other person feels. In two studies, subjects learned about a disadvantaged high school student who applied to college and was rejected from every school. Subjects felt angrier when they learned that the student’s friend caused the bad outcome than when the student made a well-intentioned mistake, but they did not think the student felt angry. The difference in subjects’ anger was mediated by changes in appraisals of agency. The student believed the rejections were caused by bad circumstances and felt sad in both conditions. The results extend research on empathy and other vicarious emotional experiences by supporting appraisal as a process that is involved in feeling emotions for other people.
