The first research was completed in 53 years and the second research was completed in two years. Another difference is that the first study relied on different kinds of sampling, not the second one. The first one contains quota sampling, as the researcher knows exactly who he wishes to select for the research participants. The second study included random and coincident sampling of data observation and collection. I believe that the research by Jennings, Hahn and Farrington (2014) is not as effective as Myer's research.
Bite analysis is a subjective method. It usually involves investigating traces of victims or objects remaining in the crime scene and comparing their impressions with the impression of the tooth taken from the suspect: (1) the characteristics of the tooth, The placement varies widely from person to person; (2) the skin (or other marking surface of the crime scene) can reliably capture these unique features. Bimark analysis begins with the examiner judging whether the injury is a trace caused by human teeth. (1) can not be excluded due to byte marking, (2) can be excluded owing to bit marking, or (3) uncertainty
The theory of analysis or evaluation is the process of systematically verifying the theory using different standards depending on the authors of the proposed analysis method, including: The main purpose of the theory's origin, meaning, logical applicability, usefulness analysis theory is to determine the potential contribution to scientific knowledge. It also helps to increase cohesiveness from a practical point of view by adding knowledge, enables identification of errors and discrepancies, and allows the use of actual theories 5, 6.
Grounded Theory Approach and its Application to Information Systems The grounded theory approach provides logically consistent data collection and analysis procedures for text analysis. The initial purpose of the grounded theory approach was to develop a research method that systematically derives the theory of human behavior from empirical data. A rational theoretical method tries to discover what is happening. It is usually applied to texts obtained by interview, observation and other data collection methods. The explicit use of the theoretical basis is the collection of data from participants who have different views on the phenomena to be studied and must adapt to the development of the theory. Here there is a clear resonance, the concept of the preparation of Ingarden and the transparency of the objectivity represented by the individual.
