<strong>Abstract:</strong> The financial performance of Insurance firms plays a vital role in increasing the sector's market value and leads to the economy's overall growth. There exists substantial empirical literature on fundamental risk factors and the financial performance of commercial banks and microfinance institutions. However, few studies have delved much into the relationship between fundamental risk factors and the financial performance of Insurance firms. The downward financial performance trend of the Insurance firms in Kenya is a cause for concerns among various stakeholders. The

Abstract:

The Risk Assessment (RA) of pollutants from contaminated sites and landfills is a major environmental issue in Europe, due to the large number of sites and to the importance of groundwater protection. The high number of contaminants and the lack of knowledge of their environmental properties and their ecotoxicological and toxicological characteristics complicate the problem. Furthermore, this information about the chemicals has to be combined with the data relative to the territory and to the targets. We will describe the problems relative to each topic involved in the process, and we will pro

Abstract:

Rainfall is a natural phenomenon that needs to be studied more deeply and interesting to be analyzed. It involves numbers of human activities such as aviation, agriculture, fisheries, and also disaster risk reduction. Moreover, the characteristics of rainfall data follows seasonality, fluctuation, not normally distributed and it makes traditional time series challenging to use. Therefore, neurocomputing model can be used as an alternative to extraction information from rainfall data and give high performance also accuracy.

For three countries of similar economic characteristics, I ratify previous studies of the impact of fundamental macroeconomic and foreign exchange variables influencing country risk, as captured by the Emerging Market Bond Index (EMBI).

Abstract:

Our willingness to take risks, our ability to wait or the speed with which to make decisions are central features of our personality. However, it is now recognized that impulsive and risk-taking behaviours are not a unitary construct, and different aspects can be both psychologically and neurally dissociated. The range of neurochemicals and brain systems that govern these behaviours is extensive, and this may be a contributing factor to the phenotypic range seen in the human population. However, this variety can also be pathological as extremes in risk-taking and impulsive behaviours are chara

Abstract:

SiC MOSFETs face short-circuit issues in practical applications. When a short circuit occurs in a SiC MOSFET, the high current density causes rapid heat generation, leading to a short short-circuit withstand time. This, in turn, increases the risk of device damage or even the burnout of the entire electrical equipment. To ensure the safe and reliable operation of SiC MOSFETs in electrical systems, research on their fundamental characteristics, short-circuit behavior, and protective driving mechanisms is crucial.

Abstract:

The article discusses the architecture of the formation of indicators, criteria, measures and risk assessment scales necessary in risk management systems based on the fundamental axioms of management theory and the principles of risk theory to build a risk management structure. As the most effective modeling method, it is proposed to use a hybrid one using the advantages of both formal and informal methods and models in building an adaptive risk management system in enterprises on a bottomup basis. To remove the emerging contradictions of indicative risk indicators, it is proposed to use a mul

Abstract:

The last thirty years have witnessed a fundamental change in the regulation of infrastructure industries. Whereas firms were subject to rate of return regulation and protected from entry in the past, they now face various forms of incentive regulation, competition is actively promoted by many regulators, and both regulators and the firms they regulate must often confront rapid technological progress. This paper surveys the literature on the investment implications of different regulatory schemes, highlighting the relevance of modern investment theory, which puts risk and intertemporal issues,

Abstract In comparison with other types of construction, the development of rock engineering design codes has been slow. Codes must, however, be developed with relevant discipline-specific characteristics in mind. This paper, therefore, presents a generic design framework for rock engineering. The framework is based on the presumption that rock engineering design must be viewed as decision-making under uncertainty, which makes the design process subject to general risk management principles, as risk is defined as “effect of uncertainties on objectives” (ISO 31000). Thus, rock engineering desig

Abstract:

Spectral analysis has been widely applied to the detection of bifurcation and the determination of the extent to which dynamic instability and chaotic responses develop. However, because spectral analysis employs stationary sinusoids in representing time-varying signals of inherent nonlinearity, the use of Fourier domain methodologies would inexorably risk misinterpreting the true characteristics and obscuring the underlying physics of the nonlinear system being investigated. The fact that the amplitude and frequency of all the individual spectral component of a nonlinear, nonstationary dynami

Abstract:

Reproductive investment, including the number of offspring produced, is one of the fundamental characteristics of a species. It is particularly important for island vertebrates, which face a disproportionate number of threats to their survival, because it predicts, among other things, a species’ resilience to environmental disruption. Taxa producing more offspring recover more quickly from environmental perturbations and survive environmental change better. However, ecologists do not understand which primary drivers shape a species’ reproductive investment well. Here, we compare the reproducti

Natural hazards are classified according to their severity based on their impact on various human activities (economic, infrastructure, development, etc.…). A natural event only becomes a threat when associated with "Mortgages" measurable in terms of damages, whether material or human losses. Among the natural phenomena of interest in northeastern Morocco, natural hazards threatening paved roads are notable. The natural and human characteristics of the area, as well as the potential interactions among them in terms of exploitation, adaptation, and mobility, are the fundamental drivers of these

An earthquake is one of the critical natural disasters that causes a massive impact on life and property in the areas it occurs. From the past earthquake patterns, the increase in the number of earthquakes in southern peninsular India can be observed. The increasing number of earthquakes is one of the critical reasons for shifting Chennai from zone II (least active) to zone III (moderately active) by the Bureau of Indian Standards. The soil column's natural frequency and time period are the key parameters for seismic design and construction. Furthermore, compared to shear wave velocity, the fu

Abstract:

The human mind is not as good at processing large amounts of information as we might like. Psychologists have shown that human beings are only able to juggle small numbers of related and often conflicting pieces of information without making judgment errors. As a result, individuals faced with the vast amounts of information available to support investment decisions often find themselves swamped by the enormity of the task; unable to see the wood from the trees. Technical analysis is a field of financial markets research that works to address the above problem by focusing on a single, commonly

Pathogens that can be transmitted between different host species are of fundamental interest and importance from public health, conservation and economic perspectives, yet systematic quantification of these pathogens is lacking. Here, pathogen characteristics, host range and risk factors determining disease emergence were analysed by constructing a database of disease–causing pathogens of humans and domestic mammals. The database consisted of 1415 pathogens causing disease in humans, 616 in livestock and 374 in domestic carnivores. Multihost pathogens were very prevalent among human pathogens
