Cancer may be due to genetic cause. At present environmental pollution is a serious problem may cause cancer to living-beings specially to human. As I am an agricultural scientist indiscriminate use of agricultural inputs like ground water use for irrigation purpose may cause arsenic contaminant to surface water use for drinking purpose . Use of synthetic high-analysis urea fertiliser contain 46% water soluble nitrogen as nitrate use for agricultural crop cultivation ;generally in upland condition about 50% use by the crop and in submerged paddy soil about 30% use by the crop ; rest about 50 to 70 % contaminate ground water with nitrate use for drinking purpose . It has been observed by W.H.O. that drinking water for living-beings as human-being consumption contain 0.05 milligram arsenic and 50 milligram nitrate to nitro-samines per litre of drinking water may cause cancer. Use of synthetic plant protection chemicals contain nickel to lungs cancer and arsenic to cancer. So,sustainable use of organic agro-chemicals and its awareness programme very much essential to prevent cancer in living-beings.

The original Braun & Clarke (2006) article does mention the possibility of using a pre-planned codebook (a deductive approach), but all the examples they have ever given derive the codebook from the data (an inductive approach). There is also a third, hybrid approach, where you being with a pre-planned codebook and update during your reading of the data.

thanks i want to use a inventory as a frame work to analyze the diary text. i wonder if the categories or the main constructs of this inventory should be mentioned as a main themes and what i extract from the written text as subcategories? in that case i think the result would be reported in quantitative way rather qultitive which i think is not a thematic analysis. i t would be more like checking something by a checklist

.looking forward to your response.

thanks for your response.

If you have a pre-determined codebook and you are treating the main constructs in that codebook as your themes, then you would definitely not be doing thematic analysis. For TA, you need to create your themes, based on what you discover when you code the data.

In particular, it sounds like you would be counting your codes, so that would be a quantitatively oriented form of content analysis.

thanks, u can say that again.

so
