The degree of coverage of knowledge has varied according to the time and country of publication.
It is also worth noting that the Clarke and Nebulas are both limited by country of publication, whereas the Hugos are not.
The authors, date and country of publication, study type, patient group, outcomes and key results of these papers have been represented in a table.
The analysis included establishing the types of materials, differences between resources used across the departments within the faculty, the journals referenced most frequently and the holdings of such titles by the library and lastly the age, language and country of publication of journal articles referenced.
In this study we analysed these 744 articles and classified them by year into: type of environment (e.g., zoo, farm and laboratory); taxonomic classification (e.g., mammal, bird, etc).; type of enrichment (e.g., food, sensory, etc).; subject area (e.g., neurosciences and agriculture); country of publication; and gathered data on experimental design (e.g., sample sizes).
Additionally, the association between country of publication and the proportion of qualitative research was of borderline significance.
Items of the table include report title, journal name, year of publication, type of control, number of participants and country of publication.
For the purpose of describing the secular trend of publication of qualitative research (aim 1) we examined the proportion of qualitative research in the journals over a 10 year period (1998 2007), and also stratified by journals' country of publication.
For aim 2, we assessed the association between the publication of qualitative research over the 10 year period and independent variables (i.e. country of publication, editorial/methodological papers, aim/guidelines, and impact factor).
