| Abstrak | : | Saat ini, humanisme sering dikaitkan dengan ateisme. Seorang humanis sering dianggap sebagai orang-orang yang tidak beriman. Apakah memang demikian yang dimaksud dengan humanisme? Memang humanisme, tepatnya humanisme sekular, yang berkembang pada abad ke-20, sangat bersifat ateis (humanisme ateis), namun salah kalau humanisme hanya diartikan dalam konteks ateisme. Artikel ini mencoba untuk memberi suatu wacana yang lebih luas tentang makna humanisme. |
Kernel Meets Sieve: Post-Regularization Confidence Bands for Sparse Additive Model

| Halaman | : | 2084-2099 |
| Abstrak | : | We develop a novel procedure for constructing confidence bands for components of a sparse additive model. Our procedure is based on a new kernel-sieve hybrid estimator that combines two most popular nonparametric estimation methods in the literature, the kernel regression and the spline method, and is of interest in its own right. Existing methods for fitting sparse additive model are primarily based on sieve estimators, while the literature on confidence bands for nonparametric models are primarily based upon kernel or local polynomial estimators. Our kernel-sieve hybrid estimator combines the best of both worlds and allows us to provide a simple procedure for constructing confidence bands in high-dimensional sparse additive models. We prove that the confidence bands are asymptotically honest by studying approximation with a Gaussian process. Thorough numerical results on both synthetic data and real-world neuroscience data are provided to demonstrate the efficacy of the theory. Supplementary materials for this article are available online. |

| Abstrak | : | Pemahaman kita sulit membayangkan bahwa imam dapat terlibat dalam kehidupan politik. Semacamnya ada keyakinan pemahaman, adalah "tabu" kalau imam terlibat dalam kehidupan politik. Alasannya jelas, imam itu berkaitan dengan pekerjaan suci di sekitar altar dan sakramen, sedangkan politik sudah terlanjur diidentikkan dengan kegiatan yang penuh intrik dan kotor. Persoalannya sekarang, apakah pemikiran dikotomis semacam ini masih tepatuntuk kehidupan Gereja dan pelayanan imam yang makin kompleks dalam arus deras globalisasi zaman ini? Tulisan kecil ini bermaksud memberikan refleksi teologis atas persoalan imam dan politik, untuk menerangkan beberapa gagasan pokok seperti: kalau bicara imam dan politik, maka mesti dimulai dari pembicaraan tentang Gereja dan politik; apa artinya imam terlibat dalam politik; dan perlukah imam cuci tangan terhadap politik ? |
Statistical Inference for Average Treatment Effects Estimated by Synthetic Control Methods

| Halaman | : | 2068-2083 |
| Abstrak | : | The synthetic control (SC) method, a powerful tool for estimating average treatment effects (ATE), is increasingly popular in fields such as statistics, economics, political science, and marketing. The SC is particularly suitable for estimating ATE with a single (or a few) treated unit(s), a fixed number of control units, and large pre and post-treatment periods (which we refer as “long panels”). To date, there has been no formal inference theory for SC ATE estimator with long panels under general conditions. Existing work mostly use placebo tests for inference or some permutation methods when the post-treatment period is small. In this article, we derive the asymptotic distribution of the SC and modified synthetic control (MSC) ATE estimators using projection theory. We show that a properly designed subsampling method can be used to obtain confidence intervals and conduct inference whereas the standard bootstrap cannot. Simulations and an empirical application that examines the effect of opening a physical showroom by an e-tailer demonstrate the usefulness of the MSC method in applications. |
AGAMA DI TENGAH JERIH PAYAH HIDUP BERSAMA

| Abstrak | : | Karangan ini mau melihat bagaimana agama, lewat proses dialog antaragama yang berpangkal pada pengalaman penderitaan/realitas paska konflik kekerasan memberi sumbangan berarti dalam proses politik dengan tindak pengakuan bersalah, memohon maaf dan mengampuni. Politik bukan melulu soal riuh rendah persaingan dan saling jegal, tapi juga proses di mana kekalahan dan kekeliruan diakui, dan permohonan maaf dan pengampunan diberikan. Proses seperti inilah yang menandai rekonsiliasi untuk membangun hidup bersama paska konflik kekerasan. Dalam tindakan seperti itu, masa lalu yang keliru diterima dan menjadikannya sebagai basis untuk untuk membangun masa depan yang lebih cerah. |
Adaptive Sparse Estimation With Side Information

| Halaman | : | 2053-2067 |
| Abstrak | : | The article considers the problem of estimating a high-dimensional sparse parameter in the presence of side information that encodes the sparsity structure. We develop a general framework that involves first using an auxiliary sequence to capture the side information, and then incorporating the auxiliary sequence in inference to reduce the estimation risk. The proposed method, which carries out adaptive Stein’s unbiased risk estimate-thresholding using side information (ASUS), is shown to have robust performance and enjoy optimality properties. We develop new theories to characterize regimes in which ASUS far outperforms competitive shrinkage estimators, and establish precise conditions under which ASUS is asymptotically optimal. Simulation studies are conducted to show that ASUS substantially improves the performance of existing methods in many settings. The methodology is applied for analysis of data from single cell virology studies and microarray time course experiments. Supplementary materials for this article are available online. |
Bayesian Hierarchical Models With Conjugate Full-Conditional Distributions for Dependent Data From the Natural Exponential Family

| Halaman | : | 2037-2052 |
| Abstrak | : | We introduce a Bayesian approach for analyzing (possibly) high-dimensional dependent data that are distributed according to a member from the natural exponential family of distributions. This problem requires extensive methodological advancements, as jointly modeling high-dimensional dependent data leads to the so-called “big n problem.” The computational complexity of the “big n problem” is further exacerbated when allowing for non-Gaussian data models, as is the case here. Thus, we develop new computationally efficient distribution theory for this setting. In particular, we introduce the “conjugate multivariate distribution,” which is motivated by the Diaconis and Ylvisaker distribution. Furthermore, we provide substantial theoretical and methodological development including: results regarding conditional distributions, an asymptotic relationship with the multivariate normal distribution, conjugate prior distributions, and full-conditional distributions for a Gibbs sampler. To demonstrate the wide-applicability of the proposed methodology, we provide two simulation studies and three applications based on an epidemiology dataset, a federal statistics dataset, and an environmental dataset, respectively.

| Nama Majalah/Jurnal | : | Fenomena |
| Volume / Edisi | : | XIII/-, MEI (No. 1) |
| Halaman | : | 51-54 |
| Abstrak | : | raksi: Teologi Politik harus berpihak pada kaum tertindas. Keberpihakan teologi politik direalisasikan dalam praksis hidup sosio-politis sebagai locusnya. Untuk itu teologi politik membutuhkan media yang secara efektif menyadarkan dan memberdayakan masyarakat yang apolitis agar terlibat aktif memperjuangkan keadilan. Media yang biasa digunakan teologi politik adalah wacana. Namun wacana saja tidak cukup, karena ada sekian banyak orang yang pendidikannya rendah dan bahkan butuh huruf, maka dibutuhkan media yang lain yaitu praksis iman yang liberatif. |
Mixed-Effect Time-Varying Network Model and Application in Brain Connectivity Analysis

| Halaman | : | 2022-2036 |
| Abstrak | : | Time-varying networks are fast emerging in a wide range of scientific and business applications. Most existing dynamic network models are limited to a single-subject and discrete-time setting. In this article, we propose a mixed-effect network model that characterizes the continuous time-varying behavior of the network at the population level, meanwhile taking into account both the individual subject variability as well as the prior module information. We develop a multistep optimization procedure for a constrained likelihood estimation and derive the associated asymptotic properties. We demonstrate the effectiveness of our method through both simulations and an application to a study of brain development in youth. Supplementary materials for this article are available online. |
