title: Survey of Botswana Political Participation, 1970: Secondary School Sample
title: Version 1

description: This study is part of a larger investigation that focused
 on political awareness and participation in Botswana. Three separate
 surveys were conducted, with an elite sample (SURVEY OF BOTSWANA
 POLITICAL PARTICIPATION, 1970: ELITE SAMPLE [ICPSR 7350]), a sample of
 the adult population ((SURVEY OF BOTSWANA POLITICAL PARTICIPATION,
 1970: MASS SAMPLE [ICPSR 7362]), and a sample of secondary school
 students (the present study). The questionnaire elicited views on the
 structure of local and national decision-making processes and the
 relationship between traditional (tribal) and modern (elected) loci of
 power. Variables assessed respondents' perceptions of the power
 structure, their participation in local politics and other
 decision-making processes, their political knowledge, and views of
 community cohesion. Demographic data include age, sex, religion,
 tribal affiliation, intra-tribal class, media usage, parents'
occupations, and sources of income.
description: Three vocational ("workers' brigade") schools and five
 regular secondary schools with different curricula, student-body
 compositions, and sources of financial support were selected for the
 sample. Classes of beginning, intermediate, and graduating students
 were then selected within the sampled schools and all students in
these classes were asked to complete the questionnaire.

title: Pattern of Human Concerns Data, 1957-1963
title: Version 1

description: Of the 14 nations included in the original study, these
 data cover the following ten: Brazil, Cuba, Dominican Republic, India,
 Israel, Nigeria, Panama, United States, West Germany, and
 Yugoslavia. (The data for Egypt, Japan, the Philippines, and Poland
 are not available through ICPSR.) In India and Israel the interviews
 were conducted in two waves, with different samples. Besides
 ascertaining the usual personal information, the study employed a
 "Self-Anchoring Striving Scale," an open-ended scale asking the
 respondent to define hopes and fears for self and the nation, to
 determine the two extremes of a self-defined spectrum on each of
 several variables. After these subjective ratings were obtained, the
 respondents indicated their perceptions of where they and their
 nations stood on a hypothetical ladder at three different points in
 time. Demographic variables include the respondents' age, gender,
 marital status, and level of education. For more information on the
 samples, coding, and the means of measurement, see the related
publication listed below.
description: Separate samples were drawn in each country. All samples
 were intended to be crossnational, except for the kibbutz sample in
 Israel. However, both India samples underrepresent females, and the
 sample from Cuba was drawn exclusively from urban areas. In addition,
 the samples from Brazil, Cuba, the Dominican Republic, India, Nigeria,
 Panama, and the United States were weighted to achieve the intended
representation.

 multiply punched variables, it is inappropriate to assume that the
 first response of a multiple response variable is more important than
 the rest: the current order of responses is an artifact of the
 technology used to record and recover them. It is even possible to
 have a missing data code followed by further substantive responses in
 some cases. (2) These data files were originally released separately,
 under ICPSR study numbers 7023-7031, 7085-7086, and 7258. They are now
 concatenated into one data collection as 7023. References in the
 codebooks to the old study numbers should be ignored. (3) The codebooks

title: Political Regimes and Regime Transitions in Africa, 1910-1994
title: Version 1

description: This data collection focuses on political regimes and
 regime transitions in 47 countries in sub-Saharan Africa. The first
 part of the dataset contains information on the characteristics of
 post-colonial political regimes from independence to December 31, 1989
 (63 variables). Economic variables include GNP per capita, inflation,
 structural adjustment programs, overseas development assistance, and
 external debt, while social indicators concern ethnic and religious
 fragmentation. Political variables provide a listing of every national
 election in Africa from independence to 1989, for totals of 106
 presidential and 185 parliamentary contests, the number of political
 parties, association groups, and media outlets in each country in 1975
 and 1989, and type of political regime, including the duration of each
 regime in years and the total number and mode of previous regime
 transitions up to 1989. The second part of the dataset covers the
 political dynamics of regime transitions for the five-year period from
 the beginning of 1990 to the end of 1994 (36 variables). The
 researchers created a standardized framework to identify and
 categorize the key events and features of political transitions,
 concentrating on landmark events such as political protests,
 liberalization reforms, elections, and changes of government in each
 country. In addition, the researchers assembled a complete set of
 standard election results for every multiparty contest in Africa
 between 1990 and 1994, along with information on whether observers
 ruled the vote as free and fair, whether incumbents were ousted, and
whether losers accepted the results.

title: Data from: Long-term fertilization impacts on metal(loid) transfer from soil to wheat in a 120-year fertilization experiment - using 87Sr/86Sr isotopes as metal(loid) tracer

description: Mineral and organic fertilizers are widely used to sustain food production but can also contribute toxic metal(loid)s to agricultural systems. However, their long-term impacts on metal(loid) accumulation in soil and crops remain insufficiently explored. This study uses a unique 120-year field experiment to demonstrate that organic (manure), mineral (NPK), and combined mineral+organic fertilization increased total soil concentrations of Zn, Cd, Pb, As, and U. For the first time, we use the 87Sr/86Sr isotopic fingerprint to trace metal(loid) transfer from fertilizer to soil into wheat grains. Metal(loid) concentrations in wheat grains were primarily governed by fertilization-induced changes in soil geochemistry affecting their mobility in soil. For example, mineral fertilization lowered soil pH, mobilizing cationic Cd and increasing its accumulation in wheat grains by 70%. Organic fertilization raised soil pH and organic matter, reducing Cd concentrations in wheat grain to below unfertilized ones. The 87Sr/86Sr in wheat grains matched that of triple superphosphate, which is one of the fertilizers used in mineral fertilization, indicating that wheat Sr and co-occurring Cd were primarily derived from the phosphate fertilizer. In contrast, the behavior of the oxyanion As was distinct, with concentrations in grain increasing by 70% under mineral+organic compared to mineral fertilization alone. Changes in As mobility in both mineral treatments significantly correlated with 87Sr/86Sr. Overall, this study demonstrates long-term metal(loid) enrichment in soil and wheat from mineral fertilization and establishes 87Sr/86Sr as a robust tracer of fertilizer impacts. These findings underscore the need for targeted fertilization strategies to reduce contaminant accumulation in agroecosystems.

title: Canadian National Election Study, 1965
title: Version 1

description: This study consisted of a survey administered to eligible
 Canadian voters after the 1965 national elections. Open-ended
 questions measured the respondents' attitudes toward the problems
 confronting Canada and various campaign issues, as well as their
 political efficacy and trust in government. Provincial and regional
 conflicts and affinities were explored through several questions
 inquiring which provinces were more powerful, better off, and worse
 off. The respondents were also queried about their political party
 attachments, voting behavior, campaign activities, and attitudes
 toward campaign financing. Demographic data include age, sex, marital
 status, education, religion, occupation, and country of birth, if
applicable.

title: Dutch Election Study, 1970-1973
title: Version 1

description: This election study was designed as a three-wave panel,
 with the first wave conducted shortly after the Dutch Provincial
 Council elections of March 18, 1970 (1,838 respondents), the second
 wave after the April 1971 parliamentary election (1,262 of the
 first-wave respondents), and the third wave after the parliamentary
 election of November 1972 (972 of the original respondents). In
 addition, a questionnaire was mailed to respondents who had refused an
 interview in the first or second wave, with a total of 356 responses
 obtained from this mailing. The study focused on the partisan
 orientations of the Dutch people. Questions were asked in each wave
 about party identification, electoral choices in the three
 parliamentary elections as well as local elections, awareness of
 candidates, issue importance, and political activities. In addition,
 Wave Two concentrated on the concept of representation: questions
 focused on citizens' perceptions of the stance of political parties
 with respect to national issues such as abortion, civil disturbances,
 aid to developing nations, income distribution, taxation, and defense
 spending, as well as respondents' opinions on the responsiveness of
 representatives to citizen demands. The third wave
 measured changes in attitudes and opinions during the period
 covered by the entire study. Many of the questions on public policy
 stands were repeated. All three waves contain information on
 respondents' family, sex, religion, marital status, education, and
occupation.
