Risk Assessment of an Environmental Liability in the Commercialization of Hydrocarbons-A Secondary Publication

The risk analysis evaluates the probability of occurrence with the impact of said risks.In the hydrocarbon sector,an environmental liability is an improperly abandoned facility,soil contaminated by spills or others.The objective of this work is to define a risk management plan.The characterization of the residue and the area was carried out.Hazardous events were identified:overflow spill,soil contamination by infiltration,as well as radiant heat and suffocating and toxic fumes from a fire.The matrix method was applied considering the probability of occurrence against vulnerability.The danger of infiltration implied a high level of risk.The risk management plan was drawn up,its main action being the liquidation of the pool and the sanitation of the area.

Determination of Liability for Violation of “Sexual Autonomy” and Compensation for Mental Damages

At the legislative level in China,there has been insufficient theoretical preparation to explicitly include“sexual autonomy”within the scope of general personality rights.In handling the increasing number of disputes related to violations of“sexual autonomy,”judicial biases have emerged during the trial process when courts determine the attribute of the right to“sexual autonomy.”This situation necessitates a clear legal analysis of the concept and attributes of“sexual autonomy”to establish its essential attribute as a personality right,and,from the perspective of legal doctrine,enable the justification of the right to“sexual autonomy”as either a general personality right or other personality interests,thereby providing theoretical support for courts to“adjudicate according to law.”By delineating and categorizing instances of violations of“sexual autonomy,”the constitutive elements and fundamental characteristics of such violations can be clarified.By examining the legal norms governing civil litigation and civil litigation associated with criminal cases concerning violations of“sexual autonomy,”the responsibility determination,remedies,and existing regulatory loopholes regarding violations of“sexual autonomy,”especially in cases involving both criminal and civil matters,can be defined.Based on this foundation,the legal basis,determination mechanism,and compensation standards for claiming compensation for mental damages resulting from violations of“sexual autonomy”can be elucidated.

Recovering implied risk-neutral probability density function using SVR

Using support vector regression （SVR）, a novel non-parametric method for recovering implied risk-neutral probability density function （IRNPDF） is investigated by solving linear operator equations. First, the SVR principle for function approximation is introduced, and an SVR method for solving linear operator equations with knowing some values of the right-hand function and without knowing its form is depicted. Then, the principle for solving the IRNPDF based on SVR and the method for constructing cross-kernel functions are proposed. Finally, an empirical example is given to verify the validity of the method. The results show that the proposed method can overcome the shortcomings of the traditional parametric methods, which have strict restrictions on the option exercise price; meanwhile, it requires less data than other non-parametric methods, and it is a promising method for the recover of IRNPDF.

Extracting Information on Implied Volatilities and Discrete Dividends From American Option Prices

This paper deals with options on assets, such as stocks or indexes, which pay cash dividends. Pricing methods which consider discrete dividends are usually computationally expensive and become infeasible when one considers multiple dividends paid during the option lifetime. This is the case of long-term options and options on indexes. The first purpose of this paper is to assess efficient and accurate numerical procedures which yield consistent prices for both European and American options when the underlying asset pays discrete dividends. The authors then analyze some methodologies to extract information on implied volatilities and dividends from quoted option prices. Implied dividends can also be computed using a modified version of the well-known put-call parity relationship. This technique is straightforward, nevertheless, its use is limited to European options, and when dealing with equities, most traded options are of American type. As an alternative, the numerical inversion of pricing methods, such as efficient interpolated binomial method, can be used. This paper applies different procedures to obtain implied volatilities and dividends of listed stocks of the Italian derivatives market （IDEM）.

Proposing a novel comprehensive evaluation model for the coal burst liability in underground coal mines considering uncertainty factors

Coal burst is a severe hazard that can result in fatalities and damage of facilities in underground coal mines.To address this issue,a robust unascertained combination model is proposed to study the coal burst hazard based on an updated database.Four assessment indexes are used in the model,which are the dynamic failure duration(DT),elastic energy index(WET),impact energy index(KE)and uniaxial compressive strength(RC).Four membership functions,including linear(L),parabolic(P),S and Weibull(W)functions,are proposed to measure the uncertainty level of individual index.The corresponding weights are determined through information entropy(EN),analysis hierarchy process(AHP)and synthetic weights(CW).Simultaneously,the classification criteria,including unascertained cluster(UC)and credible identification principle(CIP),are analyzed.The combination algorithm,consisting of P function,CW and CIP(P-CW-CIP),is selected as the optimal classification model in function of theory analysis and to train the samples.Ultimately,the established ensemble model is further validated through test samples with 100%accuracy.The results reveal that the hybrid model has a great potential in the coal burst hazard evaluation in underground coal mines.

Rapid genetic screening of Charcot-Marie-Tooth disease type 1A and hereditary neuropathy with liability to pressure palsies patients

We used the allele-specific PCR-double digestion method on peripheral myelin protein 22 （PMP22） to determine duplication and deletion mutations in the proband and family members of one family with Charcot-Marie-Tooth disease type 1 and one family with hereditary neuropathy with liability to pressure palsies. The proband and one subclinical family member from the Charcot-Marie-Tooth disease type 1 family had a PMP22 gene duplication; one patient from the hereditary neuropathy with liability to pressure palsies family had a PMP22 gene deletion. Electron microscopic analysis of ultrathin sections of the superficial peroneal nerve from the two probands demonstrated demyelination and myelin sheath hyperplasia, as well as an ＇onion-like＇ structure in the Charcot-Marie-Tooth disease type 1A patient. We observed an irregular thickened myelin sheath and ＇mouse-nibbled＇-Iike changes in the patient with hereditary neuropathy with liability to pressure palsies. In the Charcot-Marie-Tooth disease type 1A patient, nerve electrophysiological examination revealed moderate-to-severe reductions in the motor and sensory conduction velocities of the bilateral median nerve, ulnar nerve, tibial nerve, and sural nerve. Moreover, the compound muscle action potential amplitude was decreased. In the patient with hereditary neuropathy with liability to pressure palsies, the nerve conduction velocity of the bilateral tibial nerve and sural nerve was moderately reduced, and the nerve conduction velocity of the median nerve and ulnar nerve of both upper extremities was slightly reduced.

Implied volatility estimation of bitcoin options and the stylized facts of option pricing

The recently developed Bitcoin futures and options contracts in cryptocurrency derivatives exchanges mark the beginning of a new era in Bitcoin price risk hedging.The need for these tools dates back to the market crash of 1987,when investors needed better ways to protect their portfolios through option insurance.These tools provide greater flexibility to trade and hedge volatile swings in Bitcoin prices effectively.The violation of constant volatility and the log-normality assumption of the Black–Scholes option pricing model led to the discovery of the volatility smile,smirk,or skew in options markets.These stylized facts;that is,the volatility smile and implied volatilities implied by the option prices,are well documented in the option literature for almost all financial markets.These are expected to be true for Bitcoin options as well.The data sets for the study are based on short-dated Bitcoin options(14-day maturity)of two time periods traded on Deribit Bitcoin Futures and Options Exchange,a Netherlandsbased cryptocurrency derivative exchange.The estimated results are compared with benchmark Black–Scholes implied volatility values for accuracy and efficiency analysis.This study has two aims:(1)to provide insights into the volatility smile in Bitcoin options and(2)to estimate the implied volatility of Bitcoin options through numerical approximation techniques,specifically the Newton Raphson and Bisection methods.The experimental results show that Bitcoin options belong to the commodity class of assets based on the presence of a volatility forward skew in Bitcoin option data.Moreover,the Newton Raphson and Bisection methods are effective in estimating the implied volatility of Bitcoin options.However,the Newton Raphson forecasting technique converges faster than does the Bisection method.

Public Broadcasting in Brazil＂ Challenges to Overcome a Symbolic Liability

A survey of opinion conducted by the Observatory of Public Broadcasting in Latin America indicates that one of the biggest challenges for Brazilian public broadcasting lies in changing the perception that has been crystallized by the public in relation to such stations. Initial analysis of the data obtained so far shows that the respondents have a negative image in relation to public media. At times, the people manifest themselves in favor of the principles that should delimit the performance of radios and TVs, such as diversity, independence, and differentiation from commercial media, but, which are not fully followed. At other times, they criticize the quality of programming and the political-governmental character of these stations. In this critical scenario, the paper presents a discussion on the challenges facing the sector considering the complex historical, cultural, and economic policy circumstances, that have contributed to the maintenance of this ＂symbolic liability＂ between media and the audience/citizens, and which reflects on the possible strategies to face the problem.

The Fundamental Need of Reform in Company Law in England: Parent Company’s Liability for Debt of Insolvent Subsidiary

Based on the fact that the parent company has actual control over the subsidiary company,this paper analyzes the possibility of the parent company using the subsidiary company to seek benefits and damage the interests of creditors.Moreover,under the intangible protection of the current limited liability system and the independent personality of the company,it can“retreat”.This is undoubtedly against the original intention of the establishment of enterprise groups and has great potential harm to creditors.In addition,on the basis of the relief measures for the rights and interests of the parent company caused by the bad behavior of the subsidiary,the legal defects that should be carefully considered are determined.Considering whether there are other remedies that may have the same effect as disclosure,some are more moderate than disclosure.With Britain’s strong caution about lifting the veil,a more moderate direction could be considered.

Study on the Tort Liability of Electronic Commerce Platform

Today,the rapid development of electronic commerce(E-commerce)has added a new driving force for China’s economic development.However,all kinds of legal problems have followed,such as uncontrolled production and sale of fake goods,frequent malicious complaints,endless unfair competition,and illegal infringement,which have harmed the legitimate interests of consumers and seriously damaged the market order and fair competition.In order to provide some theoretical and realistic reference for the development of China’s E-commerce industry,this paper focuses on the relevant problems in the field of“infringement”of E-commerce platforms for in-depth thinking,and puts forward suggestions for solving the existing problems based on the development status of E-commerce platforms.

Spontaneous combustion liability of coal and coal-shale: a review of prediction methods

This study presents a review of the various methods to predict the spontaneous combustion liability of coal and coal-shale. The relative propensity of coal to undergo self-heating can be established by different methods. These methods are well established in their usage, but the fact that no particular test method has become a standard to predict the spontaneous combustion liability indicates that doubt still exists as to the validity of all of them. The underlying principle of all the tests is that the more readily the coal undergoes exothermic oxidation, the more liable it is to self-heat. Comprehensive studies that centres on the international position on research being conducted by academics, different research institutes and industries on spontaneous combustion of coal and coal mine fires were evaluated. Relationships between the geochemical analysis (proximate and ultimate analysis, forms of sulphur, petrographic properties, X-ray diffraction and X-ray fluorescence) and spontaneous combustion testing methods (numerical and experimental approaches) used to predict the spontaneous combustion liability of coal were reviewed. The combination of these tests provides a better understanding of the mechanism that controls the spontaneous combustion phenomena. However, irrespective of the extensive studies that have been conducted over time, spontaneous combustion is still a major problem in the coal value chain.

Replenishment policy and inventory optimization for supply-hub with liability period consideration

A replenishment decision-making model for supply-hub is firstly established from the angle of supplier, and optimal replenishment decision of the supplier is analyzed. Then, inventory optimization model for supply-hub is formulated from the angle of the manufacturer, and the optimization algorithm for obtaining optimal inventory levels is given. The result shows that liability period decides the share of the inventory cost between two sides in supply chain. With the increase of liability period, the service level has been quickly reduced even though the manufacturer's cost has been cut down by transferring the inventory cost to the supplier. As to the safety inventory, if the lower bound of components safety inventory increases, the supplier's cost will rise up more slowly than the liability period does, while the service levels increases as the safety inventory's lower bound is raised.

Analysis of spontaneous combustion liability indices and coal recording standards/basis

The characterization of the physical and chemical properties of coal on a standard provides an understanding of its characteristics towards spontaneous combustion.The trend of linear relationships between coal recording standards(%air-dried(ad),%dry(db)and%dry ash free(daf)basis)of 30 selected coal samples from the Witbank coalfields and spontaneous combustion liability indices were evaluated.The spontaneous combustion liability indices of these samples were evaluated by crossing point temperature(XPT),Stage II Slope,FCC(Feng,Chakravorty,Cochrane)and the Wits-Ehac tests,while the coal properties were determined from the proximate and ultimate analyses.The results obtained from these coal properties were related to different liability indices to develop trends of linear relationships using regression analysis.The ad basis indicated higher correlation coefficients than the db and daf basis for the XPT and FCC index,while the daf showed higher correlation coefficients than the ad and db basis for the Wits-Ehac index.It was found that the trend of linear relationships of these coal properties differs from one liability index to the next.The XPTs showed a better trend followed by the Stage II Slope on the coal properties among the spontaneous combustion liability indices evaluated.

A Liability Division Method for Harmonic Pollution Based on Line-Transferred Power Components

The existing liability division methods for harmonic pollution are either inexplicit or incomplete in physical meaning. To compensate these defects, two new methods are proposed based on line-transferred power components in this paper. At first, all harmonic sources are represented by ideal equivalent current source, line current components and bus voltage components of a source are determined by stimulation of this source with all other sources disabled. Then, the line-trans- ferred power component owing to a source under all sources action together is determined by the theory of line-transferred power components, and called source’s line-transferred power component. At last, the liability of a source for line-end harmonic pollution is divided by two methods: the ration of the source’s line-transferred active power component to the total line-transferred power, and the ration of projection of the source’s line-transferred complex power component to absolute value of the total line-transferred complex power. These two methods are taken into account not only harmonic voltage but also harmonic current in the liability division. Simulation results show that the proposed liability division method based on active power component is the most effective and ideal one.

On Environmental Quality Standards and Finding of Liability for Environmental Pollution Torts

Though bearing technical and legal attributes,environmental quality standards are neither rules nor regulatory documents.With the binding force coming from the legal norms where they are cited,environmental quality standards are designed and implemented as a yardstick for measuring environmental quality.They also play a role in the functions of goal setting,merit appraisals,inspiration,supervision and accountability in conjunction with the legal norms and administrative plans where they are cited.Characteristically,environmental quality standards adopt sort management in concept,take holistic values and methodologies,establish phased goals and accept the resulting policy choices.These standards are not applicable to determine tort liability caused by environmental pollution from the perspective of legal norms but provide limited evidence for finding the same in the view of factual analysis by delivering scientific support to prove negative effects on the environment.Hence,environmental quality standards do contribute to finding torts,thus making the production of evidence less difficult.Also,they can be used to prove the relevance between torts and damage.
