  • Supplementary Material for Traditional Agricultural Practices and the Sex Ratio Today Alberto Alesina1,2, Paola Giuliano3,2,*, Nathan Nunn1,2
    Supplementary Material for Traditional agricultural practices and the sex ratio today Alberto Alesina1,2, Paola Giuliano3,2,*, Nathan Nunn1,2 1 Harvard University. 2 NBER. 3 UCLA. *Correspondence to: [email protected] The Supplementary Material provides details on the data sources and the robustness of the analysis for the results derived in the paper. Additional details on the Ethnographic Atlas The Ethnographic Atlas was constructed by George Peter Murdock. It contains ethnographic information for 1,265 ethnic groups worldwide. The period in which the information was collected varies by ethnicity, with the earliest observation dates coming from ethnicities in the Old World (where early written evidence is available) and the most recent information dating around the 20th century, for those parts of the world without a written history and directly observed by anthropologists. All societies are observed prior to industrialization. In total, 23 ethnicities are observed during the 17th century or earlier, 16 during the 18th century, 310 during the 19th century, 876 between 1900 and 1950, and 31 after 1950. For nine ethnicities, an exact year is not provided. The variable v39 classifies each ethnic group as being in one of the following three categories: (1) the plough was absent, (2) the plough existed at the time the group was observed, but it was not aboriginal, and (3) the plough was aboriginal, having existed prior to contact. Using this information, we construct an indicator variable that equals one if the plough was ever adopted during the pre-industrial period (whether aboriginal or not) and zero otherwise. Of the 1,156 ethnicities for which information exists, for 997 the plough was absent, for 141 the plough was adopted (and aboriginal), and for 18 it was adopted, but after European contact.

  • Data Encoding: All Characters for All Countries
    PhUSE 2015 Paper DH03 Data Encoding: All Characters for All Countries Donna Dutton, SAS Institute Inc., Cary, NC, USA ABSTRACT The internal representation of data, formats, indexes, programs and catalogs collected for clinical studies is typically defined by the country(ies) in which the study is conducted. When data from multiple languages must be combined, the internal encoding must support all characters present, to prevent truncation and misinterpretation of characters. Migration to different operating systems with or without an encoding change make it impossible to use catalogs and existing data features such as indexes and constraints, unless the new operating system’s internal representation is adopted. UTF-8 encoding on the Linux OS is used by SAS® Drug Development and SAS® Clinical Trial Data Transparency Solutions to support these requirements. UTF-8 encoding correctly represents all characters found in all languages by using multiple bytes to represent some characters. This paper explains transcoding data into UTF-8 without data loss, writing programs which work correctly with MBCS data, and handling format catalogs and programs. INTRODUCTION The internal representation of data, formats, indexes, programs and catalogs collected for clinical studies is typically defined by the country or countries in which the study is conducted. The operating system on which the data was entered defines the internal data representation, such as Windows_64, HP_UX_64, Solaris_64, and Linux_X86_64.1 Although SAS Software can read SAS data sets copied from one operating system to another, it impossible to use existing data features such as indexes and constraints, or SAS catalogs without converting them to the new operating system’s data representation.
