Different types of forensic data are used for forensic identification, primarily fingerprint and DNA evidence. Two samples are compared—samples taken from the suspect and trace evidence left at the crime scene. If the samples match, a source attribution can be made. Examiners determine whether a person should continue to be a suspect on the basis of sample similarity. If all other sources can be excluded, individuation has been achieved. The four ways an expert can use to communicate to a jury that forensic identification has been made are via (1) a qualitative statement (how strong the match is); (2) a simple match statement (the evidence is consistent with the suspect’s guilt); (3) a match plus statistics statement (the evidence is consistent with the suspect’s guilt, and we have the statistics to back up this finding); and (4) an individuation statement (the match perfectly identifies the suspect). Guidelines allow an expert giving testimony to provide only one of three conclusions—inconclusive results, exclusion of the suspect, or individuation.
Unfortunately, the narrowness of these guidelines can lead jurors to falsely believe that fingerprint evidence is absolute; for example, the jury has no information about possible false positive rates. For evidence to be scientifically meaningful, it should be reliable (consistent) and valid (measure what it says it is measuring). DNA evidence can be used to identify an individual by comparing the genetic profile found at the crime scene to that of a suspect. Sometimes there is a clear match, but when the DNA sample is incomplete, poorly collected, or poorly stored, the results can be ambiguous. This is why DNA evidence is usually accompanied by a probability statement (a random match probability) declaring how likely it is that the match occurred by chance.
A different, less objective type of evidence is fingerprints, whose patterns are described as a series of loops, whorls, and arches. Despite the popular culture claim that each person’s fingerprints are unique, no evidence exists to support this notion. In addition, the processes used to compare fingerprints from the crime scene (latent prints) to the suspect’s are not standardized. In addition, individual bias may corrupt the matching process if the examiner believes the prints are from a guilty suspect. Subjectivity also comes into play when bite marks or bullet striations are being compared. All of these comparative analyses require a known, captured, suspect or weapon for any comparisons to even be made.
Measures to eliminate some of the bias inherent in the matching process include proficiency testing and certification. In proficiency testing, analysts are given a sample (e.g., the suspect’s DNA and DNA from the crime scene that is not the victim’s). They then are asked to make a judgment whether there is a match. Because they cannot be biased by knowing the “suspect’s” identity, since the samples are also obtained from known individuals, it is relatively easy for laypeople like jurors to determine whether the experts’ statements are accurate or inaccurate. Still, when jurors are presented with DNA evidence, they tend to undervalue the accompanying probabilities, which causes them the place more faith in the evidence.
In this assignment, you will analyze Fiedler’s Contingency Theory and learn to identify the most effective leadership style to use in different situations.Using the South University Online Library or the Internet, conduct research to gain a greater understanding of Fiedler’s Contingency Theory.John, a health management student completing an internship at Memorial Hospital, has been appointed chair of a multidisciplinary clinical taskforce by the hospital’s CEO. The taskforce will design a new operational system to reduce the waiting time of patients entering the hospital’s emergency room (ER). Although John had no clinical experience, he had successfully completed a course in operations management prior to beginning his internship and was excited to apply his new knowledge for solving a “real” problem for the hospital. The hospital CEO told John that when a patient entered the hospital’s ER, it could take up to eight hours from the time the patient was initially triaged by a nurse to the time the patient was either discharged home or admitted as an inpatient by the physician. The CEO said, “Due to quality of patient care issues, this timeframe is unacceptable and the taskforce needs to come up with solutions to this problem. My goal is to reduce the “turnaround” time for the patient from eight hours to two hours.” Prior to being assigned as the chair of this taskforce, John had informally observed the operations of the hospital’s ER and noted that many of the bottlenecks causing patient care delays were caused by operational issues such as nurses filling out duplicate forms and a lack of communication between the hospital departments (for example, radiology) when the ER physicians ordered tests or were waiting for test results to confirm their diagnoses. These bottlenecks caused a slow turnover of the ER’s examination rooms and unnecessary paperwork resulting in the ineffective use of both the physicians’ and nurses’ time. In addition to John, the CEO assigned Dr. Smith, the medical director of the hospital’s ER, and Mary, the ER nurse manager, to the taskforce. As chair of the taskforce, John scheduled an initial meeting for 10:00 a.m., the following Monday. John was surprised that both Dr. Smith and Mary arrived twenty minutes late to the meeting saying that this was “taking valuable time away from their normal assignments.” John started the meeting by first introducing himself. Before this meeting, he had no interactions with Dr. Smith and Mary. He then reviewed the current statistics of the average wait time for a patient presenting to the ER and the hospital’s CEO desire to reduce this time. He then opened the meeting for comments and suggestions. Dr. Smith spoke first, “In my opinion, the current operational systems that we have in place are just fine. We just need more ER physicians and examination rooms so that more patients can be seen.” Dr. Smith told John to recommend that the operational systems were good enough and that the hospital should build a new wing for additional ER exam rooms and hire more physicians. Interrupting Dr. Smith, John said, “The hospital has a very limited capital budget and no funds have been allocated for building more facilities. We need to redesign the operational system to be more efficient and effective.” Dr. Smith gave John a stern look and reminded him that he, not John, was the medical director and therefore, knew what is needed and what is best for the hospital’s ER. Mary was the next to speak. She recommended that more nurses be hired so patients could be triaged quicker when they first present themselves in the ER. Dr. Smith disagreed, saying, “Hiring more nurses is not the solution because even if patients were triaged quicker, there aren’t enough examination rooms to move the patients to!”John was just about to remind them of the taskforce’s purpose, when an overhead page indicated that both Dr. Smith and Mary were needed in the ER immediately. By now, patients were lined up in the hallways waiting to be seen in the ER. Dr. Smith told John to make the hiring and building recommendations to the CEO. The meeting adjourned, with Dr. Smith and Mary running off to the ER where patients were waiting to be seen. John sat in the empty meeting room and thought, “The CEO is not going to be happy with the taskforce’s recommendations.” He wondered, “As chair of this taskforce, what could I have done to produce the desired outcome?” John knew that hiring more physicians and nurses and building more examination rooms was not the answer. The answer was better coordination and integration of the ER’s operating systems.What is Fiedler’s Contingency Theory? How did it develop? What are its applications? What are its pros and cons?Does everyone have just one leadership style or can it vary? Why? What factors exert pressure to influence a shift in leadership style? Are the factors exerting pressure to influence a shift in leadership style appropriate with respect to merit and measure?

Ravi – What is a Hyperplane?
In science, a hyperplane H is a direct subspace of a vector space V to such an extent that the premise of H has cardinality one not exactly the cardinality of the reason for V. As such, if V is a n-dimensional vector space than H is a (n-1)- dimensional subspace. Instances of hyperplanes in 2 measurements are any straight line through the source. In 3 measurements, any plane containing the starting point. In higher measurements, it is helpful to think about a hyperplane as individual from a relative group of (n-a)- dimensional subspaces-with the end goal that the whole space is divided into these relative subspaces. This family will be stacked along the extraordinary vector (up to sign) that is opposite to the first hyperplane. This “representation” permits one to handily comprehend that a hyperplane consistently separates the parent vector space into two areas (kumar, 2017).
In AI, it might be valuable to utilize strategies, for example, bolster vector machines to learn hyperplanes to isolates the information space for grouping. The most widely recognized case of hyperplanes by and by is with help vector machines. Right now, a hyperplane sums to learning a straight, regularly in the wake of changing the space utilizing a nonlinear bit to loan a direct examination subspace that isolates the informational index into two districts for parallel order. In the event that the dimensionality of the informational collection is more prominent than 2, this might be played out numerous occasions to accomplish a multi-way order (YANG, MENG, WEN & WU, 2013).
Applications of the hyperplane.
Common Language Processing – Support vector machines are valuable in both content and hypertext grouping, since they lessen the measure of named preparing cases required. Both for inductive and transudative strategies.
Picture Classification – Using hyperplanes expands picture acknowledgment and division exactness.
Biosciences – This strategy has demonstrated valuable to quickly order proteins in obscure substances with high exactness, which radically chops down the examination time when reading new mixes for potential wellbeing employments (YANG, MENG, WEN & WU, 2013).
Vamshi – When carrying out data analysis, we are sometimes interested in finding the classification that the data points in the dataset have. This is where the use of support vector machines comes in and we have to make use of hyperplanes so that we can classify the data. As a machine learning language algorithm, classification with the use of hyperplanes can be implemented in languages such as R and Python. Their implications and in uses related to classification and regression have made this process have some real-life applications where hyperparameters are set.
Classification with the use of separating hyperplanes deploys an approach which requires that the separating hyperplane can perform classification of data in a binary class. The only caveat to the process of separating hyperplanes is that the classifier should be as far from the points in the dataset as possible. “It is important to be able to classify data discriminatively because, in many of the applications of the process, the parameters in use are not fixed and are adjusted regularly”. (Pang, Ozawa, & Kasabov, 2005).
The hyperplanes are essentially linear functions that help us get the difference between two or more categories of data points we might be interested in. In many instances, these data points are in the same class and the use of separating hyperplanes is efficient in such cases because it finds the best possible separation between the binaries. According to (Xu, Yu, Tresp, Xu, & Wang, 2003), “classification is helpful in scenarios where there is a need to have distinct distinctions between data streams of interest”. The use of classification with hyperplanes is especially popular because it can be used in many dimensions.
Bhanuteja – Added Value of Simulation Models
Decisions on a company’s further course of action are very often derived from flow charts or from spreadsheets which are not very suitable for the representation of processes and their synchronizations (Weisel, 2011). Experience shows that such a more static approach can be successful only conditionally, since planning and realization frequently differ from each other substantially. This also can be seen by the following analogy: If, at the examination of a patient, only the description of the human body was taken into account, then no proper diagnosis could be made in most cases. To obtain a satisfactory diagnosis of a patient’s condition, the so-called dynamic values which parameterize the processes and their interplay (e.g., current blood values, blood pressure, the ECG) are necessary.
With business processes we have a quite similar situation. Here, too, only the dynamic data and the consequences derived from them make a realistic judgment and improvement of the processes possible. But since the processes are substantially more transparent than the biological processes in the above analogy, it is possible with a suitable tool and with sensible effort to make an exact computer model of the process landscape with which the processes and their synchronization can be represented, visualized, calculated and optimized. Such exact models with which one can improve the processes are necessary if one wants to obtain qualified statements which help to take the right decisions at upcoming organizational requests. In this, the real added value of simulation models can be seen.
For the application of simulation techniques, the visual simulator development and execution system can be developed with which realistic and exact simulation systems for commercial, logistical and technical applications can be developed efficiently.
vijay – Chapter 6 – Features and Added Value of Simulation Models Using Different Modelling Approaches Supporting Policy-Making
This chapter examines and compares five different simulation models that are built on three different modeling paradigms, which include system dynamics, micro simulation, and agent-based modeling. System dynamics models a simulation at a global level in the attempt to describe a real-world system using analytical means through systems of varying equations. Micro-simulation modeling represents systems and processes in varying social domains to test their functioning for policy purposes (Majstorovic, Wimmer, Lay-Yee, & Davis, 2015). On the other hand, agent-based modeling is viewed as a powerful tool for developing, testing, and formalizing social theories as well as examining complex social interactions. Models compared in the chapter include VirSim, MicroSim, Modeling the Early Life-Course (MEL-C), Ocopomo’s Kosice Case, and Simulating Knowledge Dynamics in Innovation Networks (SKIN). A comparison of these models shows that none is able to address all the aspects of complex policy interactions (Majstorovic, Wimmer, Lay-Yee, & Davis, 2015). Addressing complex interactions requires the development of hybrid simulation models that comprise of different models build in different modeling theories.
An additional method of simulation other than system dynamics, micro simulation, and agent-based modeling is Discrete Event Simulation (DES), which was introduced by Geoffrey Gordon. The method is commonly used in manufacturing to evaluate planning, routing, and scheduling alternatives. The most important elements of DES are activities, entities, events, resources, and queues (Barbosa & Azevedo, 2017). DES approach can be process-oriented or event-oriented. It can be applied to model production as well as study the system behavior in response to detailed events in discrete points in time. This approach can also be applied when modeling for public policymaking.

Intensity Modulated Radiotherapy (IMRT) in the Treatment of Malignant Tumours
assignment writer With respect to the localisation, radiotherapy planning and treatment delivery, critically evaluate the role of Intensity Modulated Radiotherapy (IMRT) in the treatment of malignant tumours in the head and neck region. Introduction Intensity modulated radiotherapy (IMRT) is a radiotherapy treatment technique which can be used for a multitude of treatment sites. IMRT uses many segments to create one individual treatment field with the objective being to produce a higher conformity than would be achievable with a standard conformal treatment plan. The technique usually involves 5 to 7 beams, each with its own intensity profile, to conform the dose tightly to the target volume allowing normal tissue and critical organs to be spared. The multi leaf collimator (MLC) is controlled by the computer to create these segments (Symonds, Deehan, Mills
