Theme 3 - Research and theory (2/2)

For this week’s reflection I prepared by reading my ow blog post again and looking through my notes form the lecture in order to refresh my memory in regards to what the theme was about and what topics were important within the theme. Before the seminar I felt that I had an impression about what theory means but I found it hard to put my thoughts into words, something that I still find hard even after the seminar. However, during the lecture we were asked to explain the term and concept of theory as if speaking to a first year student. Below, I have attempted to do this but also taking into consideration two other concepts which we also focused on during the seminar; hypothesis and truth. This is also a simple and concrete way collect my thoughts and what I know about the terms which I also feel will help me in my road to understanding this week's theme.

One of the main discussions during the seminar centered around what theory is and what the difference is between theory and hypothesis. A theory is a combination of ideas, statements and definitions intended to explain something. Another idea of what theory is was provided by the lecture who said that “theory is what practice is not”. The reason why we use theories is because we need a framework when conducting research. A hypotheses is instead something that is testable and when discussing what the word itself meant we talked about how it is a guess. We also discussed the difference between scientific theory and philosophical theory. We came to the conclusion that scientific theory is based on empirical data while philosophical theory is based on an idea.

On a more philosophical note, we also discussed how truth is relative and whether or not it is possible to find the truth. We talked about how truths are tied to space and time and gave the example of how people thought the earth was flat until it was discovered that the earth was round. At a certain time, the truth was that the earth was flat and the same goes for everything we today think are true as well. Continuing this discussion we also talked about how it is only possible to find “truth” through falsification. Instead of proving that something is true, you try in different ways to prove something to be false. If you can’t prove something to be false, then you have arrived at a relative truth.

Theme 4 - Quantitative research (1/2)

The paper I have chosen is called “FoodLog: Multimedia Tool for Healthcare Applications” and is published in MultiMedia, IEEE with an impact factor of 1.694. The paper studies the app FoodLog which is a multimedia tool for recording food and researches how users experience the app in terms of e.g. how fun the app is to use, how they use the app, how often they use it and if they will keep using the app after the study is completed. The goal of the user study was to see if the participants benefited from the app and service.

Which quantitative method or methods are used in the paper? Which are the benefits and limitations of using these methods?
The chosen quantitative method in the research paper is a questionnaire where the users answered several questions using a scale of 1-5 where one was negative and 5 was positive.
The paper also used statistics from the Food Log database to see what types of food people recorded and to collect nutrition data. The paper describes how they used statistics in this case but does not discuss this at depth and does not explain what method is used when analyzing this data.

What did you learn about quantitative methods from reading the paper?
Since I have already studied several courses within the topic of theory and method (where all courses had strong focus on the definition of qualitative and quantitative methods) I did not feel that this paper specifically affected my knowledge of quantitative methods. It did however serve as a reminder of the definition of quantitative methods.

Which are the main methodological problems of the study? How could the use of the quantitative method or methods have been improved?
The main methodological problem I see is that the method used when analyzing the FoodLog data is not stated. Instead, the paper only mentions a problem that arose in connection with the analysis and explains how they solved this. In order to enhance the replicability of the study the paper would need to state what method they used here and how they analyzed the data. In regards to the questionnaire, the study only used 18 participants and does not motivate how or why they arrived at this number. In order to get a result that is more generalizable I think that a larger number of participants should have been used.

______________


One of the keywords in the text “Drumming in Immersive Virtual Reality: The Body Shapes he Way We Play” is “virtual body ownership illusions”. This term refers to the phenomenon when people are given the illusion that they exist through a different body, therefore losing sense of their own body. In this report, this is done through virtual reality where the participants play African drums and see, instead of their own hands, the hands of a Caucasian formally dressed male or a dark-skinned casually dressed male. The aim of the report was to see if a virtual body ownership illusion could affect people’s behavior and the results showed evidence that this is indeed possible. The report also argues that this type of illusion may have cognitive consequences.

Which are the benefits and limitations of using quantitative methods?
Quantitative research methods are used to understand a problem by transforming data into statistics. The method is used to quantify behaviors, attitudes and opinions from a sample group in order to generalize the results of a larger group. Benefits of the method is that it is based on facts and/or statistics and it can uncover patterns. The method is structured and can relatively easily include a large amount of people without the costs escalating in the same way as with qualitative methods. Limitations are that you cannot get a deeper view of the problem through the method, the data is at times not available, the method does not take the context of the data into consideration and the data may not be sufficient enough to explain complex situations.

Which are the benefits and limitations of using qualitative methods?
Qualitative research methods are used to gain a better understanding of a problem or situation. Benefits of the method is that you can gain insights and understand underlying problems, opinions, motivations and reasons behind e.g. actions. Benefits of the method is that you can get a deeper understanding of your research problem and there is room for both unstructured and semi-structured techniques which allows for a certain amount of flexibility within the data collection. Limitations are that the data is not generalizable, collection and analysis of data is expensive in terms of time and financial costs and the replicability is limited as the data and results are based on specific people in a specific time and space.

Theme 2 - Critical media studies (2/2)

In preparation for theme three I read the texts assigned and answered the questions that were assigned to this theme. I had a hard time understanding the actual meaning of what Benjamin and Adorno and Horkheimer were trying to convey. After the lecture and the seminar I have a very different view on the literature than before. After having discussed the texts both in group and with the seminar leader I have a much better understanding of the texts assigned.

One part of the text that I had a particular hard time understanding was the concept of nominalism. However, after the seminar I understood better that nominalism states that everything is unique and objects are only similar in our conceptions because of the way we classify and group them together. For example, we discussed that no two apples are the same. They have properties that distinguish each one from the other but because they have the same core attributes, we group them into the same category and define them as the same thing. During the seminar we also discussed that Adorno and Horkheimer believe that nominalism is a way for fascism to have status quo. If you only know what is then you cannot know what could be. If there weren’t any differences (e.g. upper and lower class) then you wouldn’t be aware that there was a different way to live life and they argue that this is a danger to society. However, when discussing these aspects we also talked about how these concepts (the concept of class and what defines a good society) are actually social constructs that only exist in our cognition.

In connection with this, another aspect that I understood better after the seminar was the connection between enlightenment and deception in terms of mass media. We discussed how it forces repeating patterns of behavior. Adorno and Horkheimer argued that movies only show a view of what the world looks like today, and not what it could look like. By constantly repeating a certain view of people then people are going to continue behaving in a certain way and repeating what they see in the pictures. Adorno and Horkheimer mean that this is deceptive as movies claim that society is a non-changing situation when they don’t show a view of what reality could look like.

Theme 3 - Research and theory (1/2)

The research journal I have chosen is called Multimedia and is a part of IEEE. The journal has an impact factor of 1.694 and I believe that it is relevant for media technology research as it publishes research articles within subjects such as multimedia user interfaces, creation and modification of multimedia applications and media creation integration editing and management, among other topics. The journals goal is to keep readers informed about technical trends and research within the subject of multimedia.

The article I have chosen from Multimedia, IEEE is “Face Matching and Retrieval in Forensics Applications” written by Anil k. Jain, Brendan Klare and Unsang Park in 2012. The article studies facial recognition approaches and looks at difficulties that exist within this field that affect the accuracy of the results. The article identifies four problems within facial recognition and try to solve how the accuracy of facial recognition within these areas can be improved. The problems are sketch recognition, aging/facial scars/marks, pose-/illumination correction and low resolution images. The research method is not explained in detail but the article states that the method chosen is a survey. A weakness within the article is the lack of explanation in regards to the method, e.g. in how they collected and analyzed the data.

The article suggests three actions for improving the accuracy of the results. First, entering images into a 3D simulator with a specific algorithm for facial aging to get an improved image of what a person might look like at a specific age. Second, the article suggests methods for image filtering on low resolution images in order to improve and enhance the quality. Third, the article claims that the accuracy of matching sketches to photographs is very low. In order to solve this problem the authors designed a facial recognition system that actually uses both the sketch and photographs together in the same program in order to get more results and hopefully a better accuracy. The problems and solutions are described in detail but the article does not explain how they collected the data and arrived at these conclusions which makes it difficult to see if the conclusions are a logical extension of the data.

In connection with the proposals, the authors of the article also warns that technology alone will not lead to more accurate results. The article argues that technology will still not always be successful when trying to find a match, which means that human interaction is still needed to interpret the result.


Briefly explain to a first year university student what theory is, and what theory is not.

The term theory can be described as explaining something and testing it through scientific methods. A theory tries to provide an understanding for how and why something is done in that particular way. Theory is not a simple list of data, variables, diagrams, methods or hypothesis.


Describe the major theory or theories that are used in your selected paper. Which theory type (see Table 2 in Gregor) can the theory or theories be characterized as?

There are five types of reasons for why theories are made; theory for analyzing, theory for explaining, theory for predicting, theory for explaining and predicting and theory for design and action. The major theory in the article I chose is design and action. When problems and weaknesses were identified the artic


Which are the benefits and limitations of using the selected theory or theories?

A benefit of the theory for design and action is that it gives instructions on how to do something. In the example of “Face Matching and Retrieval in Forensics Applications” the article offers states how to solve specific problems. However, limitations of this type of theory is that is does not necessarily provide detailed explanations about the problems or even the proposed solutions.le gave detailed suggestions of how these problems could be solved.

Theme 1 - Theory of knowledge and theory of science (2/2)

In preparation for the blog post and the seminar I read Plato’s Theaetetus and Kant's Critique of Pure Reason. I also read several other texts that discussed Theaetetus and Critique of Pure Reason in order to get a better understanding of parts of the text that I found difficult to comprehend. I also discussed questions about the text and different passages with classmates beforehand as this type of discussion helped me make sure that I actually understood the meaning of the texts instead of simply memorizing them. I also prepared during the week by attending the lecture at the beginning of the week and taking notes, especially taking note of the parts which I did not fully understand. These questions were then discussed during the seminar, both in a smaller group and also later with the lecturer after which I had a greater comprehension of the parts I was previously unclear about. During the seminar I also contributed in the smaller groups by helping explain aspects of the texts that I felt I understood to the others in the group. Everyone had their on grasp of the meanings of the texts and I felt that the group discussions were very worthwhile and rewarding.


One thing in particular I understood better during discussions at the seminar was the concept of “God’s point of view” in regards to knowledge. From what I understood, Kant means that pure knowledge without preconceptions is “godly knowledge”. It is as if God himself has this knowledge because of its overview and pureness. God, in this meaning is an observer who does not add and perspectives or preconceptions to the knowledge. However, since the human soul and mind is made up of schemas and has an organized character that automatically determines the world around us according to our preconceptions, it is not possible for humans to transcend above ourselves and receive knowledge from “God’s point of view”. Instead, we must accept this and choose a point of view to look at things from when we are looking into the world.

Theme 2 - Critical Media Studies (1/2)

Dialectic of Enlightenment
1.      What is "Enlightenment"?
Adorno and Horkheimer write that enlightenment leads to knowledge and understanding that frees people from authority (e.g. religious rules). Enlightenment means that people, through human reason, have the capacity to answer all questions previously answered by authority and do not need to adhere to authorities imposed rules.

2.      What is "Dialectic"?
The term dialectic refers to a method of examining opposing ideas and discussing these in order to elicit the truth and expose false beliefs. This is necessary because knowledge is perception and the truth can be found through discussion of different opinions and beliefs.

3.      What is "Nominalism" and why is it an important concept in the text?
Nominalism is the theory that individuals exist while abstract things (e.g. upper class and lower class) do not exist. In other words it describes a way of thinking about physical and abstract things. It is an important concept because it can be applicable to the perspective “failed Enlightenment” during the National Socialism. An example of this is how Hitler’s arguments were based on abstract things such as a master race which according to Nominalism does not exist because it is an abstract concept.


4.      What is the meaning and function of "myth" in Adorno and Horkheimer's argument?
Myths were created in order to explain what people did not understand because there was fear of the unknown. Adorno and Horkheimer argue that enlightenment wanted to dispel myths and replace the fantasy of myths with actual knowledge.


"The Work of Art in the Age of Technical Reproductivity"
1.    In the beginning of the essay, Benjamin talks about the relation between "superstructure" and "substructure" in the capitalist order of production. What do the concepts "superstructure" and "substructure" mean in this context and what is the point of analyzing cultural production from a Marxist perspective?
The concept of “superstructure” refers to for example culture which changes very slowly in a society while the concept of “substructure” refers to for example politics and economy which can change much quicker and help define society. These two concepts are dependent on each other and according to Benjamin you need to look at the substructure (and how it changes) in order to understand how the superstructure changes. Benjamin also argues that if you draw attention to changes in the substructure, you can intervene in the process that forms and changes the superstructure.


2.    Does culture have revolutionary potentials (according to Benjamin)? If so, describe these potentials. Does Benjamin's perspective differ from the perspective of Adorno & Horkheimer in this regard?
According to Benjamin, culture does have revolutionary potential and argues the example that film can promote revolutionary criticism of social conditions or that photography can have a revolutionary impact on society.  While Benjamin means that culture has revolutionary potential, Adorno and Horkheimer instead argue that technology has revolutionary potential.


3.      Benjamin discusses how people perceive the world through the senses and argues that this perception can be both naturally and historically determined. What does this mean? Give some examples of historically determined perception (from Benjamin's essay and/or other contexts).
According to Benjamin, perception can be naturally determined or historically determined which means e.g. that perception is tied to existence in space and time. Therefore, perception can be historically determined depending on the surrounding circumstances in a person’s life and can also change drastically by specific experiences. Benjamin argues cases of historically determined perception such as art where art changed and therefore also changed the people and their way of seeing art. Benjamin also gives the example of photography and how it can capture historical occurrences which has raised questions and changed the way people see and define art.


4.     What does Benjamin mean by the term "aura"? Are there different kinds of aura in natural objects compared to art objects?
     By aura, Benjamin refers to the authenticity and originality of a phenomenon or a work of art, more specifically a work of art that has not been reproduced. By this definition, all natural things have an aura as well as painting because of its uniqueness and specific place in time and space. However, photography does not have an aura as it is a copy or an image of an image. Benjamin writes that natural objects have distance and shadows which creates a unique aura.

Theme 1 - Theory of knowledge and theory of science (1/2)

1. In the preface to the second edition of "Critique of Pure Reason" (page B xvi) Kant says: "Thus far it has been assumed that all our cognition must conform to objects. On that presupposition, however, all our attempts to establish something about them a priori, by means of concepts through which our cognition would be expanded, have come to nothing. Let us, therefore, try to find out by experiment whether we shall not make better progress in the problems of metaphysics if we assume that objects must conform to our cognition." How are we to understand this? 

My understanding of what Kant says is that though objects may help us in our daily life, they do not in themselves provide us with knowledge. If objects do not provide us with knowledge then knowledge must be attained or accumulated in other ways. Kant argues that knowledge and understanding is formed and structured in the mind, through our cognition. For something to be understood in our minds, Kant means that it must be experienced and therefore we cannot gain knowledge solely by looking at an object without having any information about it. Instead we should rather focus on adapting the object to our own knowledge and use the object in order to try and understand the world around us. In other words, we need to look at an object from a bigger perspective, in it's surrounding environment and can in this way, with help from intuition and preconceptions make sense of that object. Kant argues that this principle should be adapted to solve for example the problem of metaphysics and in doing so, we will make better progress when understanding said problem.

2. At the end of the discussion of the definition "Knowledge is perception", Socrates argues that we do not see and hear "with" the eyes and the ears, but "through" the eyes and the ears. How are we to understand this? And in what way is it correct to say that Socrates argument is directed towards what we in modern terms call "empiricism"?

My understanding of Socrates argument is that eyes and ears are instruments that are used by the body in order to gather data about sight and sound. However, it is the mind that understands and makes sense of the data and adds value to it. It is in the mind that data is transformed into information and with our preconceptions and through analysis we understand the world around us. In other words, our understanding and our perception is not created simply by using our eyes to see, but our minds are an integral part of the process. We see "through" our eyes and not "with" them because our body's senses and organs are tools with which our mind can interpret the world. This means that two different people who see, smell and taste the same thing can have different perceptions as their minds take preconceptions into consideration when experiencing that thing.

Empiricism is a theory which states that knowledge derives from experience and observation where real world observations are the foundation with which to test a hypothesis (Thurén (2007)). Socrates arguments that the mind is where knowledge and perception is formed and that these perceptions are created by using senses such as sight, sound and smell in order to make sense of the world. When the mind interprets the data it receives it, in a way, gains experience. The mind can make observations and test a hypothesis which can be related to how empiricism uses observations and experience to gain knowledge.
