Italian translation of the BIS Press Release on the presentation of the Annual Report (25 June 2017)

More than any other factor, it is our asset that determines our adversary. For most of us, our asset is the corpus of sensitive personal details used for online transactions. This all comes down to how much data an adversary can glean from you, and how thoroughly it can analyze it. If your data passes through some software or hardware, its developer or maintainer enjoys some measure of control.

Like conventional criminals, criminal hackers choose easy, lucrative targets. One group in the crosshairs is made up of companies that have data on millions of users, such as private sector entities with a Web presence. Why go after one user at a time when data is collected in one place? Criminal hackers also like to hunt small organizations that have modest capital but weak information security.

Speech by Mr Claudio Borio, Head of the Monetary and Economic Department of the BIS, at the OECD-G20 High Level Policy Seminar, Paris, 11 September 2019.

Story: As many as 12 million computers worldwide have been infected with a highly encrypted computer worm called Conficker. Writer Mark Bowden details how Conficker was discovered, how it works, and the ongoing programming battle to bring down Conficker in his book Worm: The First Digital World War.

Although the etiology of schizophrenia is still unknown, it is accepted to be a neurodevelopmental disorder that results from the interaction of genetic vulnerabilities and environmental insults. Although schizophrenia's pathophysiology is still unclear, postmortem studies point toward a dysfunction of cortical interneurons as a central element. It has been suggested that alterations in parvalbumin-positive interneurons in schizophrenia are the consequence of a deficient signaling through NMDARs. Animal studies demonstrated that early postnatal ablation of the NMDAR in corticolimbic interneurons induces neurobiochemical, physiological, behavioral, and epidemiological phenotypes related to schizophrenia. Notably, the behavioral abnormalities emerge only after animals complete their maturation during adolescence and are absent if the NMDAR is deleted during adulthood. This suggests that interneuron dysfunction must interact with development to impact on behavior. Here, we assess in vivo how an early NMDAR ablation in corticolimbic interneurons impacts on mPFC and ventral hippocampus functional connectivity before and after adolescence. In juvenile male mice, NMDAR ablation results in several pathophysiological traits, including increased cortical activity and decreased entrainment to local gamma and distal hippocampal theta rhythms. In addition, adult male KO mice showed reduced ventral hippocampus-mPFC-evoked potentials and an augmented low-frequency stimulation LTD of the pathway, suggesting that there is a functional disconnection between both structures in adult KO mice. Our results demonstrate that early genetic abnormalities in interneurons can interact with postnatal development during adolescence, triggering pathophysiological mechanisms related to schizophrenia that exceed those caused by NMDAR interneuron hypofunction alone.

SIGNIFICANCE STATEMENT NMDAR hypofunction in cortical interneurons has been linked to schizophrenia pathophysiology. How a dysfunction of GABAergic cortical interneurons interacts with maturation during adolescence has not been clarified yet. Here, we demonstrate in vivo that early postnatal ablation of the NMDAR in corticolimbic interneurons results in an overactive but desynchronized PFC before adolescence. Final postnatal maturation during this stage outspreads the impact of the genetic manipulation toward a functional disconnection of the ventral hippocampal-prefrontal pathway, probably as a consequence of an exacerbated propensity toward hippocampal-evoked depotentiation plasticity. Our results demonstrate a complex interaction between genetic and developmental factors affecting cortical interneurons and PFC function.

Nitric oxide (NO) is an important signaling molecule that fulfills diverse functional roles as a neurotransmitter or diffusible second messenger in the developing and adult CNS. Although the impact of NO on different behaviors such as movement, sleep, learning, and memory has been well documented, the identity of its molecular and cellular targets is still an area of ongoing investigation. Here, we identify a novel role for NO in strengthening inhibitory GABA_A receptor-mediated transmission in molecular layer interneurons of the mouse cerebellum. NO levels are elevated by the activity of neuronal NO synthase (nNOS) following Ca²⁺ entry through extrasynaptic NMDA-type ionotropic glutamate receptors (NMDARs). NO activates protein kinase G with the subsequent production of cGMP, which prompts the stimulation of NADPH oxidase and protein kinase C (PKC). The activation of PKC promotes the selective strengthening of α3-containing GABA_ARs synapses through a GABA receptor-associated protein-dependent mechanism. Given the widespread but cell type-specific expression of the NMDAR/nNOS complex in the mammalian brain, our data suggest that NMDARs may uniquely strengthen inhibitory GABAergic transmission in these cells through a novel NO-mediated pathway.

SIGNIFICANCE STATEMENT Long-term changes in the efficacy of GABAergic transmission is mediated by multiple presynaptic and postsynaptic mechanisms. A prominent pathway involves crosstalk between excitatory and inhibitory synapses whereby Ca²⁺-entering through postsynaptic NMDARs promotes the recruitment and strengthening of GABA_A receptor synapses via Ca²⁺/calmodulin-dependent protein kinase II. Although Ca²⁺ transport by NMDARs is also tightly coupled to nNOS activity and NO production, it has yet to be determined whether this pathway affects inhibitory synapses. Here, we show that activation of NMDARs trigger a NO-dependent pathway that strengthens inhibitory GABAergic synapses of cerebellar molecular layer interneurons. Given the widespread expression of NMDARs and nNOS in the mammalian brain, we speculate that NO control of GABAergic synapse efficacy may be more widespread than has been appreciated.

Sensory systems integrate multiple stimulus features to generate coherent percepts. Spectral surround suppression, the phenomenon by which sound-evoked responses of auditory neurons are suppressed by stimuli outside their receptive field, is an example of this integration taking place in the auditory system. While this form of global integration is commonly observed in auditory cortical neurons, and potentially used by the nervous system to separate signals from noise, the mechanisms that underlie this suppression of activity are not well understood. We evaluated the contributions to spectral surround suppression of the two most common inhibitory cell types in the cortex, parvalbumin-expressing (PV+) and somatostatin-expressing (SOM⁺) interneurons, in mice of both sexes. We found that inactivating SOM⁺ cells, but not PV+ cells, significantly reduces sustained spectral surround suppression in excitatory cells, indicating a dominant causal role for SOM⁺ cells in the integration of information across multiple frequencies. The similarity of these results to those from other sensory cortices provides evidence of common mechanisms across the cerebral cortex for generating global percepts from separate features.

SIGNIFICANCE STATEMENT To generate coherent percepts, sensory systems integrate simultaneously occurring features of a stimulus, yet the mechanisms by which this integration occurs are not fully understood. Our results show that neurochemically distinct neuronal subtypes in the primary auditory cortex have different contributions to the integration of different frequency components of an acoustic stimulus. Together with findings from other sensory cortices, our results provide evidence of a common mechanism for cortical computations used for global integration of stimulus features.

In 2015 we celebrated the “International Year of Soils” and with good reason. Soil sustains all our agricultural and livestock food production, wood for fuel production, filters water so that we can drink it and fish can live in it. We also use it for construction - therefore it sustains our homes and infrastructure. As we approach the end of #IYS [...]

Mountains provide freshwater and biodiversity, and are a major source of food. By definition, they dominate their surroundings with towering height and protect valleys and their inhabitants. They play a critical part in moving the world towards sustainable economic growth and have a leading role as indicators of climate change. As we celebrate the International Mountain Day, see how much you [...]

10: EtymologyThe word pulse originates directly from the Latin puls meaning "thick gruel, porridge, mush.” 9: Pulses vs legumes, what’s the difference?The term "legume" refers to the plants whose fruit is enclosed in a pod. Pulses are a subgroup of the legume family, but the term “pulse” refers only to the dried seed. Dried beans, lentils and peas are the most commonly known and consumed types [...]

In 2016 we celebrated the International Year of Pulses and it is obvious why. Pulses are good for you, beneficial to farmers' livelihoods and have a positive impact on the environment. It is clear that even though dried beans, lentils and peas have been around for centuries, they will play a fundamental role in our sustainable future. Even though #IYP2016 has [...]

Safer Internet Day (SID) is an international education and awareness-raising effort spanning more than 100 countries around the globe to promote safer and more responsible use of online technology and mobile phones, especially amongst children and young people across the world.

Mauritius is among one of the very first countries where government has taken keen interest to protect children and youngsters on the Internet.  In this context, a Child Online Safety Action Plan was developed by the National Computer Board (NCB) and endorsed by the cabinet in 2009.  Following the aproval of the action plan, number of activities have been started on Child Online Safety since 2009 including organisation of the Safer Internet Day. 

This year is the 6th edition of Safer Internet Day which will be celebrated in Mauritius. On this occasion, CERT-MU, a division of the National Computer Board is organising several activities.  The activities are as follows:

• A half day workshop with theme "Let's create a better Internet together" in collaboration with the Ministry of Technology, Communication and Innovation and the Ministry of Education and Human Resources, Tertiary Education and Scientific Research.  The proposed workshop is targeted towards State and Private secondary school students to sensitise them on the impact of threats and consequences that improper use of the Internet may have on the youth.

• Awareness sessions on “Internet Safety” will be carried out for secondary school students (State and Private) in all four school zones of the country.  These sessions will highlight issues like sexting, sextortion, cyber bullying, online predators and identity theft etc. 

• Organisation of awareness sessions on “Dangers of the Internet” for secondary school teachers (State and Private) in all four school zones during the school holidays. Trainings on the Dangers of the Internet and how to help youngsters choose a better way of socialising in the virtual world will be organised for the teachers of  secondary schools.

• Awareness sessions for Parents, Senior Citizens and House Wives on "Secure Usage of Internet".  Parents, Grandparents and House Wives need to be aware of the dangers on the Internet and how to protect their kids online.  An awareness session will be organised to address this issue with parents, in collaboration with the PTA of secondary schools.  The Senior Citizens and House Wives sessions will take place in NCB cyber caravans and community welfare centres. 

• Dissemination of brochures on "Child Online Protection" to the students and teachers.

Using a cross-country sample of bank-dependent public fi rms we study the international spillovers of a change in banking regulation on corporate borrowing. For identi cation we examine how US rms' liabilities vis-a-vis banks, non-bank lenders and bond markets evolve after an increase in capital requirements implemented by the European Banking Authority (EBA) in 2011. We find that US firms experience a reduction in credit lines but not in term loans from EU banks.

This paper reviews post-crisis financial regulatory reforms, examines how they fit together and identifies open issues. Specifically, it takes stock of the salient new features of bank and CCP international standards within a unified analytical framework.

Recent literature has highlighted that international trade is mostly priced in a few key vehicle currencies, and is increasingly dominated by intermediate goods and global value chains (GVCs). Taking these features into account, this paper reexamines the business cycle dynamics of international trade and its relationship with monetary policy and exchange rates.
