Qualitative analysis of interview data: A step-by-step guide
 
06:51
The content applies to qualitative data analysis in general. Do not forget to share this Youtube link with your friends. The steps are also described in writing below (Click Show more): STEP 1, reading the transcripts 1.1. Browse through all transcripts, as a whole. 1.2. Make notes about your impressions. 1.3. Read the transcripts again, one by one. 1.4. Read very carefully, line by line. STEP 2, labeling relevant pieces 2.1. Label relevant words, phrases, sentences, or sections. 2.2. Labels can be about actions, activities, concepts, differences, opinions, processes, or whatever you think is relevant. 2.3. You might decide that something is relevant to code because: *it is repeated in several places; *it surprises you; *the interviewee explicitly states that it is important; *you have read about something similar in reports, e.g. scientific articles; *it reminds you of a theory or a concept; *or for some other reason that you think is relevant. You can use preconceived theories and concepts, be open-minded, aim for a description of things that are superficial, or aim for a conceptualization of underlying patterns. It is all up to you. It is your study and your choice of methodology. You are the interpreter and these phenomena are highlighted because you consider them important. Just make sure that you tell your reader about your methodology, under the heading Method. Be unbiased, stay close to the data, i.e. the transcripts, and do not hesitate to code plenty of phenomena. You can have lots of codes, even hundreds. STEP 3, decide which codes are the most important, and create categories by bringing several codes together 3.1. Go through all the codes created in the previous step. Read them, with a pen in your hand. 3.2. You can create new codes by combining two or more codes. 3.3. You do not have to use all the codes that you created in the previous step. 3.4. In fact, many of these initial codes can now be dropped. 3.5. Keep the codes that you think are important and group them together in the way you want. 3.6. Create categories. (You can call them themes if you want.) 3.7. The categories do not have to be of the same type. They can be about objects, processes, differences, or whatever. 3.8. Be unbiased, creative and open-minded. 3.9. Your work now, compared to the previous steps, is on a more general, abstract level. 3.10. You are conceptualizing your data. STEP 4, label categories and decide which are the most relevant and how they are connected to each other 4.1. Label the categories. Here are some examples: Adaptation (Category) Updating rulebook (sub-category) Changing schedule (sub-category) New routines (sub-category) Seeking information (Category) Talking to colleagues (sub-category) Reading journals (sub-category) Attending meetings (sub-category) Problem solving (Category) Locate and fix problems fast (sub-category) Quick alarm systems (sub-category) 4.2. Describe the connections between them. 4.3. The categories and the connections are the main result of your study. It is new knowledge about the world, from the perspective of the participants in your study. STEP 5, some options 5.1. Decide if there is a hierarchy among the categories. 5.2. Decide if one category is more important than the other. 5.3. Draw a figure to summarize your results. STEP 6, write up your results 6.1. Under the heading Results, describe the categories and how they are connected. Use a neutral voice, and do not interpret your results. 6.2. Under the heading Discussion, write out your interpretations and discuss your results. Interpret the results in light of, for example: *results from similar, previous studies published in relevant scientific journals; *theories or concepts from your field; *other relevant aspects. STEP 7 Ending remark This tutorial showed how to focus on segments in the transcripts and how to put codes together and create categories. However, it is important to remember that it is also OK not to divide the data into segments. Narrative analysis of interview transcripts, for example, does not rely on the fragmentation of the interview data. (Narrative analysis is not discussed in this tutorial.) Further, I have assumed that your task is to make sense of a lot of unstructured data, i.e. that you have qualitative data in the form of interview transcripts. However, remember that most of the things I have said in this tutorial are basic, and also apply to qualitative analysis in general. You can use the steps described in this tutorial to analyze: *notes from participatory observations; *documents; *web pages; *or other types of qualitative data. STEP 8 Suggested reading Alan Bryman's book: 'Social Research Methods' published by Oxford University Press. Steinar Kvale's and Svend Brinkmann's book 'InterViews: Learning the Craft of Qualitative Research Interviewing' published by SAGE. Good luck with your study.

Standard Method for Sieve Analysis of Fine and Coarse Aggregates (ASTM C136)
 
05:51
Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates Today we’re going to demonstrate the dry sieving test method used to determine the particle size distribution of fine and coarse aggregates in accordance with ASTM C136, where a sample of dry aggregate of known mass is separated through a series of sieves with progressively smaller openings to determine the particle size distribution of the test sample. The Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates is used primarily to (1) determine the grading of materials proposed for use as aggregates or being used as aggregates, and to (2) determine the compliance of the particle size distribution where applicable specifications are required, and to (3) provide necessary data for quality control of the production of various aggregate products and mixtures containing aggregates. Devices required for this test method are: a balance or scale used in testing of fine and coarse aggregate with a readability of 0.1 g for fine aggregate, and 0.5 g for coarse aggregate, or mixtures of fine and coarse aggregate; Test sieves that conform to ASTM E11 specifications; A mechanical sieving device to create motion of the particles to bounce, tumble, or otherwise turn so as to present different orientations to the sieving surface; An oven of appropriate size capable of maintaining a uniform temperature of 110 +/- 5 °C (230 +/- 9 °F); A sieve brush; a sample container or pan; a sieve pan; a sieve stack cover; and a way to record and analysis your test finding. Sieving Procedure The procedure for Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates, we first dry the test sample in an oven at a constant temperature of 110 +/- 5 °C (230 +/- 9 °F). For this demonstration we’re using a Gilson BO-350 Quincy Bench Oven. Now, measure on a balance or scale the tare weight or unladen weight of your sample container or pan. Now place the test sample into the sample container and measure its gross weight. Next, select test sieves with suitable openings to furnish enough information required by the specifications covering the material being tested. Nest the sieves in order of decreasing size of opening from top to bottom. Today we’re using Gilson 8in ASTM E11 stainless steel compliance grade test sieves. Place the sieve stack on to a sieve pan. Now place the test sample into the top sieve and then cap the sieve stack with a sieve cover. Agitate the sieves by means of a mechanical sieving apparatus for a sufficient period of time so that not-more-than 1% by mass of the material retained on any individual sieve will pass that sieve during 1 minute of continuous sieving. For this demonstration we are using the Gilson SS-15 mechanical Sieve Shaker. The SS-15 delivers superior accuracy and repeatability for particle separations for No. 4 to No. 200 size ranges by combining a back and forth lateral motion with an up and down tilting motion which causes test material to travel in an orbit on sieve surfaces. Once sieving has completed its course, measure and record the mass weight of each sample size increment on a scale or balance to the nearest 0.1 gram. Repeat this process for each sieve and the sieve pan. The total mass of the sieved sample should match closely with original mass of test sample before sieving. If the amounts differ by more than 0.3%, based on the original dry sample mass, the results should not be used, and the test should be repeated. In recording the mass of each sample size and determining the gross test sample mass you should include the total percentage of material passing each sieve, and/or the mass of material retained on each test sieve and pan, and/or the percentage of material retained between consecutive sieves (Report percentages to the nearest whole number, except if the percentage passing the 75-μm (No. 200) sieve is less than 10 %, it shall be reported to the nearest 0.1 %) For more information go to https://www.globalgilson.com/sieve-analysis-of-coarse-aggregate-from-the-field-to-the-lab-part-3 sieve analysis of coarse aggregate lab report / sieve analysis test procedure / sieve analysis pdf / sieve analysis conclusion / sieve analysis lab report / sieve analysis lab report pdf / sieve analysis graph / importance of sieve analysis / sieve analysis test pdf / sieve analysis of fine aggregate

From user feedback surveys, telephone polls, and those questionnaires at your doctors office, surveys are everywhere, but with their ease to create and distribute, they're also susceptible to bias and error. So today we’re going to talk about how to identify good and bad survey questions, and how groups (or samples) are selected to represent the entire population since it's often just not feasible to ask everyone.

Soil samples from Japan tested with gamma spectroscopy - the results
 
12:55
A while back as part of a collaboration I was sent soil samples from several places across Japan. The most notable was from Kashiwa City in Chiba Prefecture which is a known "hot-spot", an area that received significant radiological fallout after the Fukushima nuclear disaster. This can be seen documented in Science and Education Ministry (MEXT) contamination maps and other sources. The samples of soil from Kashiwa were enough to induce significant response in a hand-held Geiger counter. I carefully packaged small samples and forwarded it to Youtube user "antiprotons" (Tom) who does a lot of work with gamma spectroscopy and makes educational videos about radiation. He did an analysis of the samples and wrote about his testing methodology and conclusions. I briefly present his findings in this video. Tom's blog entry about the testing is here: http://anti-proton.com/?p=609 The report, figures, and data are here for you to review: http://anti-proton.com/japan/ Zoomable, scrollable, contamination map based on MEXT data: http://www.nnistar.com/gmap/fukushima.html Contamination maps by independent professor Yukio Hayakawa's (based on his vulcanology expertise, geography, weather, and expected fallout patterns): http://kipuka.blog70.fc2.com/ Uncivil, off-topic, or personal comments will be screened Corrections and clarifications: asuperdry's video of high radiation in his back yard is http://youtu.be/VC9CIs6-pZw (the 'I' looks like an 'l' in the font I used on the screen possibly leading to difficulty finding the video.) --- Disclaimer: I prefer to be responsible for managing my own work and as such ask that you please don't upload this video to any other Youtube channels or sites.

Soil samples sent for analysis were small and the package complied with all relevant regulations with regards to shipping such material. I make every effort to neither downplay nor exaggerate the situation. I am careful to clearly state things that are inconclusive or theories as such and provide additional references for information presented and so that viewers can do their own research and arrive at their own conclusions. Not everyone will arrive at the same conclusion, but an atmosphere of free inquiry and evaluation of all available information is critical to mitigating this situation and preventing future ones like it.

The Spectrophotometer:  A demo and practice experiment
 
06:27
The spectrophotometer is an instrument used to measure the effect of a sample on a beam of light. We can learn a lot about a substance by studying the way it interacts with light. In this video, we'll demonstrate how to use a spectrophotometer to perform a basic experiment: determining the absorbance spectrum of red food coloring. Included in the video is a short animation that illustrates the inner workings of a spectrophotometer. Special thanks to Joe Issa and the Gaston College Biotechnology department for helping to make this video. Practice using a virtual spec: http://www.ncbionetwork.org/educational-resources/elearning
