Theme 4: Quantitative research (before lecture)

I chose the paper called “A Systematic Review of Mapping Strategies for the Sonification of Physical Quantities,http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0082491”,using the bottom-up pattern to set up a list of conceptual dimensions” included in physical and auditory areas.In total,the paper is an overview of the sonification performance to deliver and interpret the certain hints as a informational carrier.The approaches are the mapping-based.In the reviewed works,mappings were identifying and forming a database of 495 entries.In some way,I think it is the one of the features for the bottom-up structure that reveal and demonstrate the results with a great details in an data-based way.Meanwhile, because of the highly intensive data demonstrations,the most of entries would be obscure in the display.For the methods itself,there would be more risks to the increasing of difficulties to filter data and statistics.

The most impressive part of the paper in my mind is the author’s angle to the consider the subjects and the methods which are kinds of decomposition and categories in the whole view.Firstly,the author tries to build up the relations with even all physical quantities with the central terms.There is a database of 495 entries to support the methods to face up the multifarious objects and reflect different responses.Then,using the bottom-up pattern is easy to clarify the complex in an explicit and systematic way.

There are some puzzles for the methods formulation and implementation.This is the system based on the potential relations between central terms and its surroundings.Generally,we must filter and categorize the specific properties which is traced and referred finally in the statistics to make the structural plan more feasible and accurate.Hence,detecting the suitable and authentic data is in the crucial aspect to facilitate the quantitative methods in some degree.I think the cases collections and assumptions from the previous publications is play a key role as the precondition to influence the progressive methods.The methods in the paper is a good way to focus on main factors and contradictions of the central objects that related with multifarious factors and neglect the contrast of quantities temporarily.

Which are the benefits and limitations of using quantitative methods?
Which are the benefits and limitations of using qualitative methods?

 In this paper,the researchers conduct the critical and accurate methods with the quantitative methods,such as the samples detection,materials uses,data analysis and etc.I think the quantitative methods could demonstrate and control the process of experiments in the authentic framework which is under the system of engineering management.It contributes to the results with more deep and extensive to set up the mathematical model so that we could conclude the exact value and other features of aimed objects.To say simply, the quantity could translate the phenomenon in the range of human’s cognition. However,the highly accurate statistics with large workloads of data analysis and collection.Probably,the qualitative methods which focus on the phenomenon and relations between objects with previous knowledge and empirical judgments is feasible to analyze  and summarize the predictions of objects with current state in a preliminary research.However,the quantitative methods should be the preconditions of qualitative analysis in some way.Only the constant interpretation of patterns and properties could be detected to brace the quantity structures and improve the accuracy of data filtering,the results can be comprehensive and meaningful. Definitely,the both should be work together for the critical and complete methods
