Wage Setting - Assignment Example The hijackers might be impersonating as accident victims and when truck drivers help them, in return they hijack the trucks. Truck hijackers might even gain unauthorized entrance into areas where trucks are parked; they might kill the person responsible for the security of the trucks and then hijack the truck and escape with them. Ans. 12 The act of checking or going through the file of the victim is one of the activities that are considered necessary while an officer of a robbery case conducts a follow-up of the case. This action is considered as necessary to cheek whether the same victim has been a victim of the case of robbery before or whether he has reported such crimes against him in the past. This action is considered necessary to match the previous crimes of robbery to the current crime of robbery in which the victim is same. This is done to find similarities between old and new cases and whether a new robber has committed the crime or the victim has been robbed for more than once by the same criminal. The act of checking past records can even help figure out whether the victim himself is connected in the crime as individuals report such crimes to conduct various frauds such as insurance frauds. Chapter 14 Ans. 1 There are various dimensions of the crime of burglary, this crime is mostly witnessed in residences and this crime is witnessed or experienced after every 15 seconds in different areas. The average loss experienced by a residence due to this crime is calculated at $1,381 and the average loss experienced by nonresidential or commercial settings is calculated at $1,615 (Swanson, 2012). Out of all the cases of burglaries, 64% of the criminals conduct a forced entry; this means that the criminal uses forceful ways of entering into the target settings. Investigations have figured out that when the crime is committed in residential setting, the criminal makes an entry from the front, where as in the case of commercial settings, the criminal makes a b ack door entry. These crimes are mostly conducted when the setting or the property is not in use by the property owners or the people who live or work over there.

The rate of this crime does not vary according to different months and seasons, and the cases of this criminal act are very difficult to solve. Ans. 8 There are various signs at the crime scene that differentiate a crime of burglary conducted by a professional burglar and the same crime committed by an armature or a juvenile. In case of juvenile burglars, juvenile burglars do not conduct ample amount of planning before they make their move, they are easily arrested as compared to professional burglars, they mostly conduct crimes in shape of groups and teams and do not strike in areas or setting where they can obtain high amount of return, they might end up making mistakes such as killing members in the residence if they are confronted by household members as they are quite confused and afraid and have a quite heavy arrest history. Juvenile burglars mostly steal portable assets and assets that are easy to move such as radio, mobile phones, gaming consoles and cash. Ans. 11 Information and leads about a particular residential or a commercial setting and what can be found in these settings is obtained by burglars through various sources.

Research methods - Assignment Example One of the major sources that can lead to invalidity and unreliability in a research is the bias of the researcher (Baumgarten 2012). Biases in research are mainly categorized into selection bias, measurement bias, and analysis bias (CEMÂ  - Research -Â  Bias & Confounding n.d.). The present study focuses on learning about the different types on bias in research studies with specific examples for each of the types. Bias and Types of Bias in Research Studies: Bias is said to have occurred in a research when the outcomes of the research are different from the actual results. For example, if a research is focused on determining the risk of a disease and the results of the research reflect consistent overestimation of the risks, then the study can be said to have been based on bias. Design of a research is largely responsible for a bias and bias in general presents error in the same direction for a repeated number of the experiments for a particular research sample and work (World Heal th Organization 2001). Thus biases need to be reduced in order to produce a reliable and valid research. Types of Bias with Examples: Selection Bias: Selection bias is defined as the bias when some participants are favored and selected over others while sampling is conducted and the research outcomes are based on experiments conducted on such samples, thereby affecting the external validity of the research (Gravetter and Forzano 2010). It is also referred to as sampling bias. As a result of such bias, the outcome of the research reflects a systematic difference between those subjects that are included and those that are not. Thus either the results are underestimated or overestimated in terms of their statistics, rates, and ratios (Peat, Mellis and Williams 2002). This means that the study cannot be considered as reliable for use. Moreover, with different outcomes than the actual results, the validity of the research also gets reduced. An example of selection bias in research is a c omparison of patients in one hospital where a new wound dressing method is applied on them, with patients of another hospital who are offered the standard method of treatment. In such a case the possibility of selection bias is significantly high since different patients in different hospitals differ in their social and biological characteristics. Thus such a research is exposed to selection bias (Stommel and Wills 2004). Allocation bias is a type of selection bias that occurs when there is a difference in the characteristics of the different samples put in different trial groups of a particular research experiment, and has significant influence on the outcomes of the research (Peat, Mellis and Williams 2002). Measurement Bias: Measurement bias is defined as the bias that occurs when biases or errors occur in the process of measurement and calculations of the data based on which the results are obtained. Such biases can result from erroneous tools of measurement, errors in calculati ons, errors while measurements are recorded, participant bias, recall bias, and so on (Howlett, Rogo and Shelton 2013). For example, if dietary recalls are considered for a 24 hours time period, then measurement biases can occur with the methods of the interview, the assumptions of coding, or
