Project description:New and disruptive technologies, including cryptocurrencies and new payment methods, are revolutionising the way people engage with finance. Although they provide significant benefits to consumers, they are also inadvertently creating new money laundering and terrorist financing risks. This paper examines the risks that are, or are predicted to be, prevalent in three technology sectors—distributed ledger technologies (including cryptocurrencies), new payment methods and financial technologies (FinTech), through a systematic scoping review process. Specifically, the paper identifies enablers of both crimes, the precise criminal methods they might facilitate, at-risk stakeholders (of exploitation and/or complicity) and risk characteristics. The study involves systematic scoping reviews of the academic and futures literatures as well as a consultation exercise with experts to assess the likely veracity of the findings. In addition to identifying an array of specific risks, we identify six underlying trends that facilitate them. We discuss these, their policy implications, future directions for research and their benefit for conducting risk assessments to assess forthcoming technological developments.

Project description:It is important to understand the amounts and types of money laundering flows, since they have very different effects and, therefore, need different enforcement strategies. Countries that mainly deal with criminals laundering their proceeds locally, need other measures than countries that mainly deal with foreign illegal investments or dirty money just flowing through the country. This paper has two main contributions. First, we unveil the country preferences of money launderers empirically in a systematic way. Former money laundering estimates used assumptions on which country characteristics money launderers are looking for when deciding where to send their ill-gotten gains. Thanks to a unique dataset of transactions suspicious of money laundering, provided by the Dutch Institute infobox Criminal and Unexplained Wealth (iCOV), we can empirically test these assumptions with an econometric gravity model estimation. We use this information for our second contribution: iteratively simulating all money laundering flows around the world. This allows us, for the first time, to provide estimates that distinguish between three different policy challenges: the laundering of domestic crime proceeds, international investment of dirty money and money just flowing through a country.

Project description:Financial and legal entities (e.g. banks, casinos, notaries etc.) have to report money laundering suspicions. Countries' engagement in fighting money laundering is evaluated-among others-with statistics on how often these suspicions are reported. Lack of compliance can result in economically harmful blacklisting. Nevertheless, these blacklists repeatedly become empty-in what is known as the emptying blacklist paradox. We develop a principal-agent model with intermediate agents and show that non-harmonized statistics can lead to strategic reporting to avoid blacklisting, and explain the emptying blacklist paradox. We recommend the harmonization of the standards to report suspicion of money laundering.

Project description:BackgroundThe Global Terrorism Database (GTD) is an open-source database on terrorist incidents around the world since 1970, and it is maintained by the National Consortium for the Study of Terrorism and Responses to Terrorism (START; College Park, Maryland USA), a US Department of Homeland Security Center of Excellence. The consortium reviews media reports to determine if an event meets eligibility to be categorized as a terrorism incident for entry into the database.ObjectiveThe objective of this study was to characterize chemical terrorism incidents reported to the GTD and understand more about the kinds of chemical agents used, the associated morbidity and mortality, the geography of incidents, and the intended targets.MethodsChemical terrorism incidents from 1970 through 2015 were analyzed by chemical agent category, injury and fatality, geographic region, and target.ResultsDuring the study period, 156,772 terrorism incidents were reported to the GTD, of which 292 (0.19%) met the inclusion criteria for analysis as a chemical terrorism incident. The reported chemical agent categories were: unknown chemical (30.5%); corrosives (23.3%); tear gas/mace (12.3%); unspecified gas (11.6%); cyanide (8.2%); pesticides (5.5%); metals (6.5%); and nerve gas (2.1%). On average, chemical terrorism incidents resulted in 51 injuries (mean range across agents: 2.5-1,622.0) and seven deaths (mean range across agents: 0.0-224.3) per incident. Nerve gas incidents (2.1%) had the highest mean number of injuries (n = 1,622) and fatalities (n = 224) per incident. The highest number of chemical terrorism incidents occurred in South Asia (29.5%), Western Europe (16.8%), and Middle East/North Africa (13.0%). The most common targets were private citizens (19.5%), of which groups of women (22.8%) were often the specific target. Incidents targeting educational institutions often specifically targeted female students or teachers (58.1%).ConclusionsChemical terrorism incidents rarely occur; however, the use of certain chemical terrorism agents, for example nerve gas, can cause large mass-causality events that can kill or injure thousands with a single use. Certain regions of the world had higher frequency of chemical terrorism events overall, and also varied in their frequencies of the specific chemical terrorism agent used. Data suggest that morbidity and mortality vary by chemical category and by region. Results may be helpful in developing and optimizing regional chemical terrorism preparedness activities.

Project description:Indicators of compliance and efficiency in combatting money laundering, collected by EUROSTAT, are plagued with shortcomings. In this paper, I have carried out a forensic analysis on a 2003-2010 dataset of indicators of compliance and efficiency in combatting money laundering, that European Union member states self-reported to EUROSTAT, and on the basis of which, their efforts were evaluated. I used Benford's law to detect any anomalous statistical patterns and found that statistical anomalies were also consistent with strategic manipulation. According to Benford's law, if we pick a random sample of numbers representing natural processes, and look at the distribution of the first digits of these numbers, we see that, contrary to popular belief, digit 1 occurs most often, then digit 2, and so on, with digit 9 occurring in less than 5% of the sample. Without prior knowledge of Benford's law, since people are not intuitively good at creating truly random numbers, deviations thereof can capture strategic alterations. In order to eliminate other sources of deviation, I have compared deviations in situations where incentives and opportunities for manipulation existed and in situations where they did not. While my results are not a conclusive proof of strategic manipulation, they signal that countries that faced incentives and opportunities to misinform the international community about their efforts to combat money laundering may have manipulated these indicators. Finally, my analysis points to the high potential for disruption that the manipulation of national statistics has, and calls for the acknowledgment that strategic manipulation can be an unintended consequence of the international community's pressure on countries to put combatting money laundering on the top of their national agenda.

Project description:The COVID-19 pandemic has made a prominent impact of social contexts on teachers' professional development in remote classroom teaching. To explore how the change has altered human-environment relationships in university language classes, this qualitative case study investigated three teachers' progressive reflection on their use of affordances for teaching Chinese as a second language (L2) during COVID-19. Under the framework of human ecological language pedagogy, three themes of emergency remote teaching emerged from monthly semi-structured interviews about the three teachers' reflective practice in remote classrooms: computer-dominant teaching conditions, flexible classroom interaction, and rational social empathy in L2 education. The findings suggest the importance of a growth mindset for L2 teachers to leverage their teaching abilities and environmental resources for continuing professional development during COVID-19 and post-pandemic periods.

Project description:Because of high purchase costs of newer vaccines, financial risk to private vaccination providers has increased. We assessed among pediatricians and family physicians satisfaction with insurance payment for vaccine purchase and administration by payer type, the proportion who have considered discontinuing provision of all childhood vaccines for financial reasons, and strategies used for handling uncertainty about insurance coverage when new vaccines first become available.A national survey among private pediatricians and family physicians April to September 2011.Response rates were 69% (190/277) for pediatricians and 70% (181/260) for family physicians. Level of dissatisfaction varied significantly by payer type for payment for vaccine administration (Medicaid, 63%; Children's Health Insurance Program, 56%; managed care organizations, 48%; preferred provider organizations, 38%; fee for service, 37%; P < .001), but not for payment for vaccine purchase (health maintenance organization or managed care organization, 52%; Child Health Insurance Program, 47%; preferred provider organization, 45%; fee for service, 41%; P = .11). Ten percent of physicians had seriously considered discontinuing providing all childhood vaccines to privately insured patients because of cost issues. The most commonly used strategy for handling uncertainty about insurance coverage for new vaccines was to inform parents that they may be billed for the vaccine; 67% of physicians reported using 3 or more strategies to handle this uncertainty.Many primary care physicians are dissatisfied with payment for vaccine purchase and administration from third-party payers, particularly public insurance for vaccine administration. Physicians report a variety of strategies for dealing with the uncertainty of insurance coverage for new vaccines.

Project description:ObjectivesThe objective of this study is to explore the association of health financing indicators with the proportion of births by caesarean section (CS) across countries.DesignEcological cross-country study.SettingThis study examines CS proportions across 172 countries.Main outcome measuresThe primary outcome was the percentage excess of CS proportion, defined as CS proportions above the global target of 19%. We also analysed continuous CS proportions, as well as excess proportion with a more restrictive 9% global target. Multivariable linear regressions were performed to test the association of health financing factors with the percentage excess proportions of CS. The health financing factors considered were total available health system resources (as percentage of gross domestic product), total contributions from private households (out-of-pocket, compulsory and voluntary health insurance contributions) and total national income.ResultsWe estimate that in 2018 there were a total of 8.8 million unnecessary CS globally, roughly two-thirds of which occurred in upper middle-income countries. Private health financing was positively associated with percentage excess CS proportion. In models adjusted for income and total health resources as well as human resources, each 10 per cent increase in out-of-pocket expenditure was associated with a 0.7 per cent increase in excess CS proportions. A 10 per cent increase in voluntary health insurance was associated with a 4 per cent increase in excess CS proportions.ConclusionsWe have found that health system finance features are associated with CS use across countries. Further monitoring of these indicators, within countries and between countries will be needed to understand the effect of financial arrangements in the provision of CS.

Project description:The ongoing novel coronavirus disease (COVID-19) pandemic makes us painfully perceive that our bullet shells are blank so far for fighting against severe human coronavirus (HCoV). In spite of vast research work, it is crystal clear that the evident does not warrant the commercial blossoming of anti-HCoV drugs. In this circumstance, drug repurposing and/or screening of databases are the only fastest option. This study is an initiative to recapitulate the medicinal chemistry of severe acute respiratory syndrome (SARS)-CoV-2 (SARS-CoV-2). The aim is to present an exquisite delineation of the current research from the perspective of a medicinal chemist to allow the rapid development of anti-SARS-CoV-2 agents.
