A sharp increase in the popularity of commodity investing in the past decade has triggered an unprecedented inflow of institutional funds into commodity futures markets. Such financialization of commodities coincided with significant booms and busts in commodity markets, raising concerns of policymakers. In this paper, we explore the effects of financialization in a model that features institut...

Empirical evidence indicates that trades by institutional investors have sizable effects on asset prices, generating phenomena such as index effects, asset-class effects and others. It is difficult to explain such phenomena within standard representative-agent asset pricing models. In this paper, we consider an economy populated by institutional investors alongside standard retail investors. In...

Ascorbic acid (Vitamin C) has long been known for its anti-cancer properties and in the present study the effects of ascorbic acid (AsA) on osteogenic differentiation, apoptosis, and signaling pathways of the human G29 osteosarcoma cell line were studied. The expression of Runt-related transcription factor-2 (RUNX2) and osteocalcin genes were evaluated by real-time polymerase chain reaction (PC...

In this paper, we examine the risk characteristics and capital adequacy of hedge funds using Value-at-Risk (VaR) as the criterion for measuring risk and estimating capital requirements. We find that a vast majority of hedge funds are adequately capitalized, with the level of under-capitalization being only 3.1% for live funds and 7.5% for dead funds. Using extreme value theory, we confirm that ...

Blackgram (Vigna mungo (L.) Hepper) yields are noticeably poor due to a shortage of improved varieties and an aggravated narrow genetic base. An attempt was made isolate novel blackgram mutants by selecting for yield-related traits derived through gamma irradiation testing the mutant genotype’s stability across different environments. The irradiated populations M1-M5 were established in backgro...

Purpose- The aim of the study is to measure efficiency real estate investment trusts traded on BIST with data envelopment analysis and Malmquist total factor productivity index. Efficiency were measured using Data Envelopment Analysis approach, both whose application fields have grown recently. Methodology- index used analyze changes in 20 operating 2019–2020–2021, as well reasons for these cha...

A phylogeny of haemosporidian parasites (phylum Apicomplexa, family Plasmodiidae) was recovered using mitochondrial cytochrome b gene sequences from 52 species in 4 genera (Plasmodium, Hepatocystis, Haemoproteus, and Leucocytozoon), including parasite species infecting mammals, birds, and reptiles from over a wide geographic range. Leucocytozoon species emerged as an appropriate out-group for t...

Let V be a finite dimensional complex vector space and W ⊂ GL(V ) be a finite complex reflection group. Let V reg be the complement in V of the reflecting hyperplanes. A classical conjecture predicts that V reg is a K(π, 1) space. When W is a complexified real reflection group, the conjecture follows from a theorem of Deligne, [20]. Our main result validates the conjecture for duality (or, equi...
