Negative Interest Rate Policies: Sources and Implications
Against the background of continued growth disappointments, depressed inflation expectations, and declining real equilibrium interest rates, a number of central banks have implemented negative interest rate policies (NIRP) to provide additional monetary policy stimulus over the past few years. This paper studies the sources and implications of NIRP. We report four main results. First, monetary transmission channels under NIRP are conceptually analogous to those under conventional monetary policy but NIRP present complications that could limit policy effectiveness. Second, since the introduction of NIRP, many of the key financial variables have evolved broadly as implied by the standard transmission channels. Third, NIRP could pose risks to financial stability, particularly if policy rates are substantially below zero or if NIRP are employed for a protracted period of time. Potential adverse consequences include the erosion of profitability of banks and other financial intermediaries, and excessive risk taking. However, there has so far been no significant evidence that financial stability has been compromised because of NIRP. Fourth, spillover implications of NIRP for emerging market and developing economies are mostly similar to those of other unconventional monetary policy measures. In sum, NIRP have a place in a policy maker's toolkit but, given their domestic and global implications, these policies need to be handled with care to secure their benefits while mitigating risks
prtH2, Not prtH, Is the Ubiquitous Cell Wall Proteinase Gene in Lactobacillus helveticusâ–ż
Lactobacillus helveticus strains possess an efficient proteolytic system that releases peptides which are essential for lactobacillus growth in various fermented dairy products and also affect textural properties or biological activities. Cell envelope proteinases (CEPs) are bacterial enzymes that hydrolyze milk proteins. In the case of L. helveticus, two CEPs with low percentages of amino acid identity have been described, i.e., PrtH and PrtH2. However, the distribution of the genes that encode CEPs still remains unclear, rendering it difficult to further control the formation of particular peptides. This study evaluated the diversity of genes that encode CEPs in a collection of strains of L. helveticus isolated from various biotopes, both in terms of the presence or absence of these genes and in terms of nucleotide sequence, and studied their transcription in dairy matrices. After defining three sets of primers for both the prtH and prtH2 genes, we studied the distribution of the genes by using PCR and Southern blotting experiments. The prtH2 gene was ubiquitous in the 29 strains of L. helveticus studied, whereas only 18 of them also exhibited the prtH gene. Sequencing of a 350-bp internal fragment of these genes revealed the existence of intraspecific diversity. Finally, expression of these two CEP-encoding genes was followed during the growth in dairy matrices of two strains, ITG LH77 and CNRZ32, which possess one and two CEP-encoding genes, respectively. Both genes were shown to be expressed by L. helveticus at each stage of growth in milk and at different stages of mini-Swiss-type cheese making and ripening
Experimental study on infusion devices containing polyvinylchloride: To what extent are they di(2-ethylhexyl)phthalate-free?
The use of medical devices containing highly criticized phthalates including di(2-ethylhexyl) phthalate (DEHP) has been challenged by European directive 2007/47/CE, put into effect in March 2010. New plasticizers are now being used to soften PVC in medical devices: trioctyltrimellitate (TOTM), di-isononylcyclohexan-1,2-dicarboxilate (DINCH) and di(2-ethylhexyl) terephthalate (DEHT). To quantify DEHP in nine DEHP-free medical devices made of PVC softened by alternative plasticizers, high performance liquid chromatography analysis with ultraviolet detection at 220 nm wavelength was achieved. An NMR spectroscopy was performed to confirm DEHP presence. Only two medical devices out of the nine tested were truly without DEHP. One of them showed traces of DEHP exceeding the threshold contamination of 0.1% in plastic mass set by REACH regulations. TOTM plasticizer is still incriminated when polyvinylchloride (PVC) is contaminated with DEHP. Manufacturers must verify the purity of their raw material. not only on PVC, but also an other soft plastics entering into the composition of medical infusion devices. The clinical consequences of exposure to certain levels of DEHP have not been evaluated. A solution could be to use alternative PVC-free materials

The Financial crisis and loan impairment provisioning in Asian banks
This chapter examines the response of a sample of Asian banks to the recognition of loan loss provision in the face of a gathering economic storm Drawing on empirical data from 2006 through 2008, this chapter focuses on the level of loan loss provisioning undertaken by the banks, with a view to generating insights into the effectiveness of the approach to loan impairment and provisioning prescribed by IAS 39-Financial Instruments: Measurement and Recognition. Given that the focus of impairment decision-making, under IAS 39, is historically oriented rather than future oriented, we argue that this may result in the diminution in the decision usefulness of the content of bank financial statements in the face of imminent, though not yet manifested, economic distress. Despite mounting evidence that substantial portions of the globe's financial and economic fabric lay in a state of severe distress, our analysis of the financial disclosures of the sample of Asian banks shows a picture at odds with this larger reality. We argue that this response is shaped by the requirements of the newly introduced accounting standard and that a broadening of the legitimate sources of evidence upon which loan impairment recognition decisions may be based, pursuant to IAS 39, should be a matter of priority.18 page(s
