New Challenges

With the advances in genotyping technologies and electronic health records (EHRs), large biobanks have been great resources to identify novel genetic associations and gene-environment interactions on a genome-wide and even a phenome-wide scale. To date, several phenome-wide association studies (PheWAS) have been performed on biobank data, which provides comprehensive insights into many aspects of human genetics and biology. Although inspiring, PheWAS on large-scale biobank data encounters new challenges including computational burden, unbalanced phenotypic distribution, and genetic relationship. In this paper, we first discuss these new challenges and their potential impact on data analysis. Then, we summarize approaches that are scalable and robust in GWAS and PheWAS. This review can serve as a practical guide for geneticists, epidemiologists, and other medical researchers to identify genetic variations associated with health-related phenotypes in large-scale biobank data analysis. Meanwhile, it can also help statisticians to gain a comprehensive and up-to-date understanding of the current technical tool development.

This research is a survey research using a questionnaire as an instrument. For testing the instrument using a test of validity and reliability. As for the technique of data analysis using multiple linear regression methods, because the variables used are more than two variables, with the F test and t test. The results of the study showed that the religiosity variable (X1) did not significantly influence the intention to buy halal cosmetics, this was indicated by the significance value&gt;α(0.24)&gt;0.05) attitude (X2) had no significant effect on the intention to buy halal cosmetics, this is shown from the significance value&gt;α(0.509&gt;0.05), subjective norm (X3) does not affect the intention to buy halal cosmetics, this is indicated from the significance value&gt;α(0,250&gt;0.05), behavioral control (X4) influences on the interest in buying halal cosmetics, this is indicated by the significance value&lt;α(0,000&lt;0.05). Simultaneously the influence of religiosity, attitudes, subjective norms, and behavioral control on the intention to buy halal cosmetic products at the Faculty of Economics and Business Ahmad Dahlan University has a significant effect on the intention to buy halal cosmetics (Y). This is evidenced by the calculation of the F test of 28,135 with a significance of 0,000.</span></p><p><span>Keywords</span><span>: </span><span>Religiosity, Attitude, Intention, Halal Cosmetics </span><span>ABSTRAK</span></p><p><span>Penelitian ini bertujuan untuk mengetahui pengaruh religiusitas, sikap, norma subyektif dan kontrol perilaku terhadap niat membeli produk kosmetik halal pada mahasiswi muslim di Fakultas Ekonomi dan Bisnis Universitas Ahmad Dahlan Yogyakarta.

Dependent Variables

This study aims to test and describe Tax Avoidance which is influenced by the Audit Committee, Return On Assets (ROA), and Leverage. This study uses two variables, namely the independent and dependent variables, and the source of data in this study in the form of financial statements of mining sector manufacturing companies listed on the Indonesia Stock Exchange (BEI) in 2015-2017. Data analysis was performed by classical assumption test and hypothesis testing in this study using multiple linear regression methods. The results of this study indicate that partially the Audit Committee and Leverage variables have a significant effect on tax avoidance, while the Return on Assets (ROA) does not affect tax avoidance.

Positive Effect

This study analyzes the participation decision and income impacts of fair-trade coffee certification on small-scale coffee producers in the Araku valley in India using panel data for 183 households and endogenous-switching and quantile regression methods. The results show that fair trade certification has a positive effect on income; the income of certified farmers is 17 percent higher on average than the income of uncertified coffee producers. Furthermore, fair trade certification has a “bottom of the pyramid” effect in that the largest income gains accrue to farmers in the poorer quantiles.
