How important are cross-cultural studies when it comes to interventions for early literacy?

I know of Schieffelin's (1990) and Gottlieb's (2004) ethnographies, the Ochs and Schieffelin language and development-centered collaborations, and a few of the textbooks. I'd welcome any and all suggestions.

Recent and Classic ones are all good. Course Syllabi/Bibliographies/Articles are excellent too! 

Thank you :)

what is the impact of mothers work on the language development of their children compared to non working mothers

Does anyone know of research on child language acquisition and compounds concerning the question if children when learning a language with no productive compound system ever attempt to form compounds?

I am looking at research on infants ability to speak and whether or not teaching an infant sign-language can help develop their verbal ability.

Development of tasks to foster  autistic children's figurative language, inference and comprehension.  

Each cultural dimension of the Hofstede's culture require to assign a constant value [C(pd) for Power Distance Index, C(ic) for Individualism Index and etc). The manual says the constant values are chosen by the user to shift her/his PDI scores to values between 0 and 100. But how to determine what to assign and how to assign are not explained. Can anyone suggest me a procedure..

Dear Colleague,

We would like to invite you to our new, large-scale cross-cultural research project.

Our previous research projects, conducted in 53 study sites, turned out to be a great success. One of our manuscripts (from a first project) was published in Journal of Cross-Cultural Psychology, other from the new project is currently under review in the same journal, one will soon be submitted to the Journal of Marriage and Family, and three more papers are in the final stages of preparations. Thanks to our efficient team work we now collaborate with, e.g., David Buss.

We would like to continue the research in the area of cross-cultural/evolutionary psychology. This time, we plan to conduct six studies.

a) Sexual Morality Project

b) Comparison of daily life touch between countries

c) Creativity study

d) Love study

e) Mate study

f) Facebook study

Now, we have collaborators from 60 countries.  Algieria, Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, Croatia, Cuba, Czech Rep, Estonia, Etiopia, France, Georgia, Germany, Ghana, Greece, Hong Kong, Hugary, India, Iran, Ireland, Italy, Korea, Latvia, Lebanon, Lithuania, Malaysia, Malta, Mauritius, Mexico, Nepal, Netherlands, New Zealand, Nigeria, Norway, Pakistan, Peru, Philippines, Poland, Portugal, Romania, Russia, Salvador, Slovakia, Slovenia, South Africa, Spain, Sweden, Switzerland, Turkey,  UK, Ukraine, Uruguay, USA.

In spite of findings on cross-cultural differences, researchers seem to be using measurement scales across cultures without checking for cross-cultural validity or adapting it appropriately. What does this trend signify? Is it the pressure to publish quickly, or the difficulty in proper rigorous validation of scales?
