A four-step approach to research synthesis was used:
1. Screening studies.
2. Critical appraisal and data extraction.
3. Data analysis.
4. Characteristics of studies.
Of the 3,259 records, only 463 studies met the selection criteria. From these, 230 were retained for analysis in the first instance. All 4,072 studies were screened in duplicate by Title and Abstract (T&A), and by full text (FT) for studies meeting the selection criteria. These steps were then checked in consultation with SL.
Our Critical Appraisal Tool (CAT) has been used in the development of two previous reviews [[@B25],[@B26]]. The purpose of the CAT is to determine the accuracy and balance of study design and results. By using this approach, we can test if some studies are unsuitable for pooled analysis, and if there are some studies that are more suitable than others. The CAT is simple to administer, reliable, and user-friendly.
Data extraction and analysis
We reviewed all retained studies in duplicate according to a structured data extraction tool, using a web-based data abstraction instrument created for this review. We included data on study design and methods, participant and community characteristics, intervention details and outcome measures. For each study, we extracted data in a manner that was responsive to each study’s methods and findings.
In stage two, we conducted a narrative synthesis of study results. We developed a coding tree that was sensitive to study design. Specific interventions were labelled as follows:
1. Firewood and charcoal production (including wood pellets).
3. Solar photovoltaic energy.
4. Other means of renewable energy.
5. Clean cooking technologies (includes gas, solar cookers and other technologies).
6. Other renewable energy technologies (includes biomass, wind power, and kerosene and LPG lighting)
7. Conventional stoves and other improved combustion technologies.
8. Self-selected traditional cooking methods (includes cookstoves, open fires and paraffin).
9. Natural building materials, such as clay, thatch or other environmentally friendly building materials.
10. Traditional techniques of choice (includes faith-healing and herbal medicine).
the figure is right. Now there are 13 variables. Do you think that can be a problem? Is it any practical?
Yes, this can be problematic. If you have a high amount of parameters, then you may actually have to estimate more parameters (clusters, constructs, variables, etc.).
You could use an exploratory data analysis to see if it is reasonable, and if so, run the SEM using that number of parameters. If it is not reasonable, then split your data into at least 5 different analyses (one for each solution).
Did you know that the word « fry » is becoming more and more commonly used? It’s something to keep in mind for the next time you see it on TV.
In a short message from the Next Generation Institute, a few words were removed on an episode of Star Trek: Voyager. It seems that some of the contents from this episode were copied and pasted from George Orwell’s book « 1984 » and carried out on several TV stations in France and Spain.
In the message, you can see that the words « frievance report », « methodology », « projection », « synchronization », « tactics » and « the war on terror » have been censored in the USA. These words were removed on the Internet in Spain, and are also censored in France. Even worse, the words « militarization » and « coercion » have been removed from the message.
Why these words? Well, over the past few years, the US Department of Defense has claimed to be able to track the activities of practically every person by following every e-mail and every website visited by the user.
In the case of the Spanish version, it seems that the removal of the words has to do with the human rights that the US government are currently violating in the Central American region, and more specifically in Honduras, through the USAID program.
Freedom on the Net recently reported:
« According to a report published by the Honduran Institute of Public Opinion, when it comes to free speech and expression, Honduras is the country with the most restricted expression, followed by Bolivia and Ecuador. « We also have the most censored Internet with Honduras leading the world with over 1672 censored websites. »
The most censored sites in Honduras are those of a human rights group, the Association of the Families of the Disappeared in Honduras
