PERBANDINGAN VOLATILITAS DAN RISIKO PASAR PRODUK DANA PIHAK KETIGA (DPK) PADA BANK MANDIRI CABANG BANDUNG BUAHBATU

Penelitian ini bertujuan untuk membandingkan perbedaan volatilitas dan risiko pasar produk Dana Pihak Ketiga (Tabungan, Giro dan Deposito) pada Bank Mandiri Cabang Bandung Buahbatu, menganalisis hasil estimasi varians dari masing-masing produk dana pihak ketiga serta mengukur tingkat kerugian maksimum yang dapat terjadi untuk masing-masing produk dana pihak ketiga dalam periode tiga tahun terakhir (2014,2015 dan 2016). Penelitian ini menggunakan model volatilitas meliputi uji Augmented Dickey Fuller (ADF) untuk melihat nilai varians untuk masing-masing produk dana pihak ketiga, kemudian menggunakan metode ARCH/GARCH beserta turunannya untuk mendapat nilai estimasi yang optimum melalui proses trial and error serta penelitian ini menghitiung tingkat Value at Risk (VaR) dengan menggunakan Historical Simulation dan Monte Carlo Simulation untuk mengukur tingkat kerugian maksimum yang dapat terjadi untuk masing-masing produk dana pihak ketiga dalam periode waktu yang berbeda. Hasil penelitian menunjukan bahwa berdasarkan hasil uji ADF bahwa p-value untuk semua kombinasi data kurang dari 0.05 artinya semua series data yang akan digunakan dalam pemodelan telah memenuhi asumsi kestatsioneran. Hasil pengolahan metode ARCH/GARCH rata-rata volatilitas tertinggi adalah produk Giro. Nilai VaR dengan menggunakan metode Historical Simulation dan Monte Carlo Simulation bahwa produk Giro selalu paling buruk disetiap tahunnya, sedangkan produk Tabungan dan Deposito cenderung lebih rendah dan konsisten.

Controversy and consensus on the management of elevated sperm DNA fragmentation in male infertility: A global survey, current guidelines, and expert recommendations

Purpose Sperm DNA fragmentation (SDF) has been associated with male infertility and poor outcomes of assisted reproductive technology (ART). The purpose of this study was to investigate global practices related to the management of elevated SDF in infertile men, summarize the relevant professional society recommendations, and provide expert recommendations for managing this condition. Materials and Methods An online global survey on clinical practices related to SDF was disseminated to reproductive clinicians, according to the CHERRIES checklist criteria. Management protocols for various conditions associated with SDF were captured and compared to the relevant recommendations in professional society guidelines and the appropriate available evidence. Expert recommendations and consensus on the management of infertile men with elevated SDF were then formulated and adapted using the Delphi method. Results A total of 436 experts from 55 different countries submitted responses. As an initial approach, 79.1% of reproductive experts recommend lifestyle modifications for infertile men with elevated SDF, and 76.9% prescribe empiric antioxidants. Regarding antioxidant duration, 39.3% recommend 4–6 months and 38.1% recommend 3 months. For men with unexplained or idiopathic infertility, and couples experiencing recurrent miscarriages associated with elevated SDF, most respondents refer to ART 6 months after failure of conservative and empiric medical management. Infertile men with clinical varicocele, normal conventional semen parameters, and elevated SDF are offered varicocele repair immediately after diagnosis by 31.4%, and after failure of antioxidants and conservative measures by 40.9%. Sperm selection techniques and testicular sperm extraction are also management options for couples undergoing ART. For most questions, heterogenous practices were demonstrated. Conclusions This paper presents the results of a large global survey on the management of infertile men with elevated SDF and reveals a lack of consensus among clinicians. Furthermore, it demonstrates the scarcity of professional society guidelines in this regard and attempts to highlight the relevant evidence. Expert recommendations are proposed to help guide clinicians

ODP Leg 125 drills forearc crust, mantle

The drillship JOIDES Resolution left Guam Feb. 20, 1989, on Leg125 of the Ocean Drilling Program. Fifteen holes at nine sites were drilled between the deep ocean trenches and island-arc volcanoes of the Mariana and lzu-Bonin regions south of Japan. Drill sites 778-781 are on the Conical Seamount east of the Marianas, andesites 732-786 were drilled in the lzu-Sonin system. These drill sites are in areas known as forearc terranes. Those terranes overlie the shallowest parts of the subcuction zones, where lithosphere is being subducted into the mantle in a northwesterly direction at about 10 centimeters a vear. This subduction has been active since the Eocene (about 45 miilion years ago), creating a complex series of island arcs and marginal ocean basins across much of' the western Pacific
