This paper aims to explore the concepts related to risks. In particular, this paper deems to tackle the utilization and limitations of risk assessment, risk characterization and epidemiologic transition of disease. Risk Assessment and Related Concepts It is essential that concepts associated with risk assessment be given high regard. Hence, the different concepts related to risk assessment need to be understood through discussion of its definition. Uncertainty There are diverse predicaments confronting the performance of risks assessment. Moreover, as stressed by Ramachandran (2011), a high level of uncertainty can make it rather daunting to lessen impacts through prescriptions for safe utilization or through the redesign of materials, products or technologies. Uncertainties may also result to lessened patronage of individuals of certain products since they are hesitant or unsure of the consequences once they employ the use of a certain product or procedure. Conversely, there are three standard approaches in reducing the likelihood of uncertainties in risk assessment as highlighted by Ramachandran (2011) and these include: data collection, extrapolation and modeling. Adequate and appropriate data generation and collection can aid in coming up with reliable data for risk assessment. Subsequently, data can also be extrapolated from studies done on similar populations to identify standards which are unavailable (Ramachandran, 2011). Finally, employing the use of numerical models may also lessen the probability of uncertainties in risk assessment for they are flexible and can incorporate diverse kinds of information and use subjective expert decision to be able to gauge standards crucial to risk assessment. Variability Loeber and Farrington (2012) had given emphasis that “considerable variability exists in the way in which risk assessments are designed and reported.” The said variations or differences may transpire first at the origin of the assessment; furthermore, instances of variability may also happen in the utilization of methods in performing risk assessments (Loeber & Farrington, 2012). Case Study After having an overview of the definitions of uncertainty and variability and when it could occur during risk assessment, this paper will then look into “Drinking Water Toxicity Profiles” by the Human Risk Assessment Branch in 1992. In the aforementioned document, particular information is provided regarding health effects and other essential data that can help in dealing with contamination of drinking water; moreover, non-regulatory concentrations of drinking water contaminants were also illustrated at which adverse health effects would not be anticipated to transpire over particular exposure durations (Human Risk Assessment Branch, 1992). This paper will specifically focus on the component, dipropylene glycol 1, 2-dinitrate. With the information presented, if human effects were taken into consideration in deriving safe water levels, uncertainty and variability issues may be evident. Since no detailed information was derived regarding human effects, it is uncertain whether it is a crucial factor in identifying safe water levels. Moreover, if ever there are certain data available, variances may be apparent since it may not be representative of the whole population. Some population groups if their lifestyle is given regard may or may not ...Download file to see next pagesRead More

Risk Factors for Disease

...? RISK FACTORS FOR DISEASE Task: Risk Factors for Disease Introduction Recent research indicates that vaccines may be dangerous to the body. It is crucial to trace the effects of different vaccines on the functioning of human beings. Pommerville (2009 pg 484) sums the detrimental effects of vaccines in the body by indicating, “Some individuals’ immune system can react differently to a vaccine”. This statement provides the platform for this paper since it seeks to understand the extended and short-term detrimental effects of vaccines on the body. It is important to analyze different categories of vaccines such as travel, which encompass yellow fever and hepatitis, as well as non-travel vaccines. 1. The source of the disease trigger... to be...

Disease and its Symptoms

... Case Study Consultant: Charles B. Nemeroff Clinician: I have a patient with the symptoms I have just described. Kindly advice Charles Nemeroff: I think I understand Ms. Vega’s situation. Based on our recent research findings and verification from other researchers, your patient is suffering because of predisposal to trauma in her childhood. Neurobiologists have established that there are hormonal, genetic, and monoamine influences on depression. Alterations in the work of certain genes, alterations in the work of certain monoamines, and hormonal imbalance, all contribute to depressive moments in a depressed patient. It has not been established if all these factors work together, but one clear finding... Case Study Consultant: Charles B....

Understanding the Limitations in Risk Assessment

...? Understanding the Limitations in Risk Assessment Understanding the Limitations in Risk Assessment We can define risk assessment as the process of defining and characterizing the type, magnitude, and impact of a possible hazard. Risk assessment plays a fundamental part in decision making where it determines the potential dangers and their influence on different parties with reference to a given situation. Risk assessment is significant in risk management and risk communication as it derives the quantitative or qualitative value of a possible hazard. Risk...

Utilization of the law and its processes

...Running head: PARALEGAL Paralegal Studies You're The following research explores various areas that describe the utilization of the law and its processes. It makes it quite clear why there is a need for the law and how effective it is in society today. Also, an understanding is given in some of the areas of how judges utilize certain powers to control areas of the law as well. The conclusion wraps up each area individually so that proper cohesive thought can be developed to form the basis of the paralegal studies. Paralegal Studies Chapter 1 1.1 Why there are Laws Law is a fundamental process within society as it controls societal behaviors and minimizes illegal...

Limitations in Risk Assessment

...of the agent. Exposure models can be used to estimate the exposures of populations based on small numbers of representative measurements. Models that predict concentration can be combined with information on human time-activity patterns to estimate exposures. Modeling may be done on long-term and short-term exposures, both of which have limitations. For example, in long-term exposure modeling, changes may occur in natural levels of exposure over time and in activity patterns of exposed persons; in short-term modeling, there are difficulties in modeling concentrations that vary widely over time. The success of risk characterization depends on conducting a systematic analysis...

From this, it is apparent that active population base surveillance system is of paramount importance in characterizing the illness where passive laboratory investigation based surveillance to support the data collected by epidemiological investigations. E. coli O157:H7 infection is regarded as a notifiable disease since 1993. As per requirements, physicians and clinical laboratories report the infection within 3 days of diagnosis to the local health authority. After review, the local health authority submits the report to MDCH, where they are further collated and analyzed. Detection of these bacteria must be specifically ordered...

The purpose of this discussion is to approach the issue of heart disease from an epidemiological standpoint in order to analyze how data relating to the topic may be used in a healthcare setting with regards to decision making concerning limited healthcare resources. When saying that heart diseases is not communicable, it is meant that it is not like a bacterial or viral infection which is transferred from host to host or in an airborne manner. It is however, a disease which is more likely to occur in those who have a...

Characterization and Analysis of Risks - Risk Communication

...Characterization and Analysis of RisksRisk Communication Risk assessment is integral to any framework which does govern the overall security of anorganization and inherent underlying activity. Within the paradigm of risk perception and terrorism (Clinton, 2006), risk assessment seeks to identify the though process and the activity that will damage normal operations. Risk assessment is important for a number of reasons. Primarily however, risk assessment enables the identification of areas to which breaches activity potentially exists. Another example of a risk assessment though...
