Application of Data Mining Technology in Financial Intervention Based on Data Fusion Information Entropy

Finance, as the core of the modern economy, supports sustained economic growth through financing and distribution. With the continuous development of the market economy, finance plays an increasingly important role in economic development. A new economic and financial phenomenon, known as financial intervention, has emerged in recent years, which has created a series of new problems, promoting the rapid increase both in credit and investment and causing many problems on normal operation of financial bodies. In the long run, it will inevitably affect the stability and soundness of the entire economic and financial system. In order to maximize the effect of financial intervention, in response to the above problems, this article uses a series of US practices in financial intervention as the survey content, combined with the loan data provided by the US government financial intervention department, and mines the data of the general C4.5 algorithm of the decision tree algorithm. Generate a decision tree and convert it into classification rules. Next, we will discover the laws hidden behind the loan data, further discover information that may violate relevant financial policies, provide a reliable basis for financial intervention, and improve the efficiency of financial intervention. Experiments show that the method used in this article can effectively solve the above problems and has certain practicability in fiscal intervention. With stratified sampling, the risky accuracy rate increased by 10%, probably because stratified sampling increased the number of high-risk samples.

Multi-day evaluation of space domain awareness architectures via decision analysis and multi-objective optimization

The US Government is the world’s de facto provider of space object cataloging data, but it is challenged to maintain pace in an increasingly complex space environment. This work advances a multi-disciplinary approach to better understand and evaluate an underexplored solution recommended by national policy in which current collection capabilities are augmented with non-traditional sensors. System architecting techniques and extant literature identified likely needs, performance measures, and potential contributors to a conceptualized Augmented Network (AN). Multiple hypothetical architectures of ground- and space-based telescopes with representative capabilities were modeled and simulated on four separate days throughout the year, then evaluated against performance measures and constraints using Multi-Objective Optimization. Decision analysis and Pareto optimality identified a small, diverse set of high-performing architectures while preserving design flexibility. Should decision-makers adopt the AN approach, this research effort indicates (1) a threefold increase in average capacity, (2) a 55% improvement in coverage, and (3) a 2.5-h decrease in the average maximum time a space object goes unobserved.

Inevitable Failure of Inconvertible Paper Money

Since the invention of paper money, it has been understood that it is difficult for its creators to resist issuing so much that it loses value. Long experience led to the single uniquely effective means of resisting this fraud: this is for the issuer to guarantee to convert their paper money, on demand, into some defined asset, such as gold, on fixed terms. With the end of the US dollar's guaranteed convertibility into gold, its value became dependent on decisions by leaders of the US government and financial system, unhindered by the need to keep it stable. Predictably, this led to unprecedented inflation of the supply of dollars, leading to ever-rising prices and continuing decline in the acceptability of dollars and US geopolitical leadership.

How to Determine the Cost of Capital for a Commercial Forestry

This paper focuses on designing a methodological workflow to fill a knowledge gap for determining the cost of capital for commercial forestry projects. Upon reviewing the literature, a method to determine the cost of capital for profit-oriented forestry seems to be lacking. Accordingly, we selected and analyzed 42 companies that do businesses worldwide, are present on the stock exchange, and possess or lease forest land. Based on their business activities (growing forest, sawmilling, final production, paper production), these companies are classified into four subgroups. An algorithm has been devised using the concept of risk diversification and the capital asset pricing model for three groups of investors and four forestry subgroups. In doing so, the real risk-free rate (0.43%) is set as the difference between an average return on 10-year US government bonds (2.59% nominal) and the 10-year average US inflation rate (2.16%). The measure of forestry systematic risk (beta coefficient) varies between 0.83 and 1.41, while the equity (stock exchange market) risk premium is set to 6%. Unsystematic risk is determined using a process of mapping which takes into account all risk elements marked as relevant for the forestry sector. This approach provides results that reveal the cost of capital varying between 5.41% and 16.55% based on the current level of an investor's portfolio diversification and the risk characteristics of the forestry subgroup. Finally, the forestry companies meeting the investor's expectations are noted as preferable investment opportunities.

The Long-Predicted Failure of the Post-Bretton Woods “Non-System”

The monetary system implemented at Bretton Woods in 1944 made the US dollar the centre of the world economic system, with 43 other countries' currencies linked to it via fixed exchange rates. However, once the US government broke its promise to redeem dollars in gold at $35 per ounce on August 15, 1971, expansion of the supply of dollars was no longer constrained, and like many currencies before it, the lack of monetary discipline led to inflation through which the value of the dollar has fallen by about 98%. The “oil shock” of the 1970s led to the introduction of the “petro-dollar” system whereby Saudi Arabia, then the largest oil producer, agreed to accept only US dollars in payment for its oil in exchange for the US government's pledge to defend it. This shored up demand for the fiat US dollar, enabling it to survive until its now approaching endgame.

Overview on Updates on Digital Dental Radiography

Wilhelm Roentgen first discovered X-rays in 1895. Since its introduction in the mid-1980s, digital radiography has surpassed traditional screen-film radiography. Since 2000, more than 75 percent of medical clinics in the United States have migrated to digital radiography (DR). In fact, the US government has ordered that all medical records be converted to digital. Indirect, direct, or semi-direct digital radiography pictures are types of digital radiography currently available. Forensic radiology is a branch of medical imaging technology that helps clinicians. Radiology technology has evolved and grown tremendously in recent years. When comparing aggregated antemortem and postmortem information, radiographs are crucial. Adopting new technologies into a dental business demands a certain amount of bravery. After all, why alter things if your practise is running smoothly? To grasp the new equipment and procedures, the dentist and his or her staff will need further training. It's not always apparent how the new strategy will influence the practice's present logistics. These factors may cause the practitioner to be hesitant to alter present techniques. In this article we’ll reviewing digital dental radiography, and what are the advantages of going digital. And also what are the challenges that face us.

The measures against the International Criminal Court (USA v. ICC): the perspective of International Law

Since its creation, the International Criminal Court has faced the refusal of the United States to cooperate, which, in addition to staying outside the Rome Statute, has undertaken a real strategy of weakening the Criminal Code. The argument put forward by the US Government against the Rome Statute is that an international treaty cannot create obligations for a non-party state and therefore the United States denies any jurisdiction of that jurisdiction over its nationals. As early as 2000, that country had unsuccessfully introduced a proposal before the Preparatory Commission to prevent bringing American military personnel to the Court. The American Service Members Protection Act (ASPA), bilateral immunity agreements and Security Council resolutions constitute the arsenal used by States at that time to neutralize the ICC. Recently, the United States signed an order authorizing the United States to prevent and penalize employees of the International Criminal Court from entering the country. The US administration, which has been critical of the ICC for months, is opposed to launching investigation into war crimes in Afghanistan. Is not that a sign of difficulty with the US Legal Justifications? In other words, does this weakness open up the possibility of prosecution in the event of a violation of international law by US?

Delay in assessing vitamin D supplements and live vaccines for tuberculosis, polio, and measles to protect people from Covid-19

Introduction: In March 2020, less than three months after China reported a cluster of pneumonia cases in Wuhan, the United States (US) government budgeted money to support development of Covid-19 vaccines. By mid-December 2020, two had been developed, tested, and received the US government’s experimental use authorization. Given evidence that vitamin D supplements and live vaccines for tuberculosis, polio, and measles reduce risks for acute respiratory infection, many experts hypothesized they might reduce risks for Covid-19 infection. Expedited randomized controlled trials, as done for Covid-19 vaccines, could have assessed their protection against C19 no later than end-July 2020. Methods: On 21 April 2021, I searched trial registries maintained by the US National Institutes of Medicine and the World Health Organization for trials with ≥400 participants to assess vitamin D or live vaccines to prevent Covid-19 infections (all or symptomatic). On 10-13 November 2021, I searched PubMed and medRxiv for results reported from these trials.Results: In April 2021, I found 32 trials (9 for vitamin D and 23 for live vaccines) proposing to assess the impact of these interventions on rates of new Covid-19 infections (all or symptomatic). Only 10 trials proposed to begin by June 2020, and only one to end in 2020. My search on 10-13 November 2021, almost 11 months after the US approved the first two Covid-19 vaccines, found results reported from only one of the 32 trials (live measles vaccine significantly reduced new symptomatic infections). Conclusions: If health experts had demonstrated similar urgency in assessing vitamin D supplements and live vaccines for tuberculosis, polio, and measles as in developing Covid-19 vaccines, trials could have reported by end-July 2020. Depending on what trials reported, these interventions could have prevented a large percentage of more than 600,000 Covid-19 deaths reported in the US from August 2020 through November 2021. Delay in assessing vitamin D has racial implications as well, since vitamin D deficiency and Covid-19 deaths in the US have been far more common among Blacks and Hispanics compared to Whites. Going forward, depending on what trials report, these interventions could help people live with Covid-19 as an endemic virus.
