=================================================== ** ** NEPS STARTING COHORT 2 - RELEASE NOTES a.k.a CHANGE LOG ** changes and updates for release NEPS SC2 4.0.0 ** (doi:10.5157/NEPS:SC2:4.0.0) ** =================================================== * Known Issues * - an updated data manual is not yet published; please use the appropriate data manual from version 1.0.0 instead - joint weights for students and parents (w_tp4, w_tp34, w_tp1234) are currently not available for wave 4 data; they are likely to be included in the next release; for further information please contact methoden@lifbi.de =================================================== * Changes introduced to NEPS:SC2 by version 4.0.0 * =================================================== General: - translation for all meta data (variable and value labels, question texts, etc) have been revised - meta data for all variables have been revised and updated where appropriate - additional wave 4 has been incorporated into the data CohortProfile: - dataset CohortProfile erroneously contained the variable "ID teacher / educator" [ID_e]; however, it is not possible to directly assign teachers and educators to children in Starting Cohort 2; assignment always has to take place using the pTarget dataset in order to corretly reflect the educator-to-child relationship; thus, this variable has been removed spSiblings: - in the spSiblings dataset, system missing values in variables "Sibling's date of birth - month" [p73221m] and "Sibling's date of birth - year" [p73221y] are incorrectly coded in version 3.0.0, leading to implausible birth dates; this has been fixed WeightsElementarySchool: - the english value label for value "3" of variable "Grouping variable for children in Kindergarten and school context" [group] is incorrect and should be "Target person from sample in wave 1, observation in school context"; this has been fixed WeightsKindergarten: - the english value label for value "3" of variable "Grouping variable for children in Kindergarten and school context" [group] is incorrect and should be "Target person from sample in wave 1, observation in school context"; this has been fixed pParent: - the concept of reflecting migrational background in NEPS SUFs has been improved in order to also represent migrants in 3.75th generation; thus, the older variables on migrational background [p400500_g1,p400500_g2,p400500_g3] in the pParent dataset have been renamed using the "v1" suffix [p400500_g1v1,p400500_g2v1,p400500_g3v1], and the new ones have been introduced - in version 3.0.0, there was an error in the derived values of target persons' CAMSIS scale (p731904_g15); this has been fixed =================================================== * Changes introduced to NEPS:SC2 by version 3.0.0 * =================================================== General: - starting with this release, all NEPS Scientific Use Files will ship with an additional, unicode-enabled Stata data set version; this version is only readable in Stata version 14 or younger, and is placed in the subdirectory "Stata14" - translation for all meta data (variable and value labels, question texts, etc) have been revised and completed - meta data for all variables have been revised and updated where appropriate - additional wave 3 has been incorporated into the data, including observations from a sample refreshment in wave 3 - regional information for German federal states have been added (for waves 1 through 3, restrospectively) to the download SUF, more fine-grained information to the RemoteNEPS and onsite variant - weighting should be performed depending on the analyses focus; thus, the Weights data set has beend split up into two files: one for the analyses of waves one and/or two [WeightsKindergarten], the other for analyses of the full sample in wave 3 [WeightsElementarySchool] CohortProfile: - in contrast to prior releases of Starting Cohort 2, a target person from now on is considered a "participant" [tx80220==1] only if he or she participated in competency testing; if there is only context information available on the target person, this person will be considered a "temporary drop out" instead [tx80220==2] pInstitution: - in versions 2.0.0 and 1.0.0, variable h401820 has been treated as a single choice variable instead of a multiple choice variable set; this has been fixed, the (re-generated) muliple choice item variables are named h40182a, h40182b, h40182c, h40182d ParentMethods: - id variable ID_t was missing; this has been fixed pTarget: - in wave 3 (grade 1) data, several educators could fill in distinct questionnaires about a single target person; this leads to two observations per target person for a total of 81 target persons; a recommendation marker [ex20100] has beend added, recommending the observation with least item nonresponse; thus, before merging data sets, unrecommended observations should be dropped, or any other mechanism reducing these multiple lines to one single observation should be imposed - variable e67801c_g1 did contain value "0" instead of missing code -55 in case of missing values in one of the source variables; this has been fixed - variable eb10030 did contain an erroneous missing code "4" instead of "-98"; this has been fixed pParent: - variable p731702 was missing in version 2.0.0; this has been fixed - variable p743040 was missing in version 2.0.0; this has been fixed spParentSchool: - for the sake of consistency between NEPS Starting Cohorts, the data set "spSchool" has been renamed to "spParentSchool" xTargetCompetencies: - competency data for wave 2 stage-specific competency tests could not be delivered in due time by the responsible data editors for version 2.0.0; integration into the "xTargetCompetencies" data set now follows in version 3.0.0, incorporating all competency assessment data up to wave 3 =================================================== * Changes introduced to NEPS:SC2 by version 2.0.0 * =================================================== General: - metadata for all datasets has been revised and updated where appropriate - variables now ship with a characteristic 'NEPS_instname' attached in Stata datasets, reporting the variable name used in the survey - wave 2 data has been fully integrated into the data - a new dataset "Weights" has been added, reflecting panel weights for the cohort; documentation is available online - a new dataset "spSchool" has been added, reflecting the target person's school history reported in the parent's interview - a new dataset "spSibling" has been added, reflecting the target person's siblings reported in the parent's interview - a new dataset "pTargetMicrom" has been added for onsite access, reflecting spatial data from "microm Micromarketing-Systeme und Consult GmbH" - a new dataset "pInstitutionMicrom" has been added for onsite access, reflecting spatial data from "microm Micromarketing-Systeme und Consult GmbH" - several bugfixes and enhancements have been integrated into this new release, influencing various variables; only the most important ones are listed in this change log pParent: - as wave 2 data makes this a panel dataset, the filename has changed from "xParent" to "pParent" - the interview process in parent's interviews does not guarantee unique ids for parents; thus, the identifier in this dataset is no longer "ID_p", but the target person's "ID_t" - three variables with information about the target person's migrational status have been calculated [p400500_g1, p400500_g2, p400500_g3]; a working paper on the generation process and theoretical background is forthcoming - values 5, 6 and 7 have been recoded to 7, 8 and 9 in 'Highest education qualification (ISCED)' [p731802_g1] - values 5, 6 and 7 have been recoded to 7, 8 and 9 in 'Partner: Highest education qualification (ISCED)' [p731852_g1] - value 96 has been recoded to -20 in 'Partner: (Highest) vocational education certificate' [p731863] in accordance with official NEPS missing codes - 'Occupation (DKZ 2010)' [p731904_g10] was erroneously in the dataset and has been removed - 'Partner: Occupation (DKZ 2010)' [p731954_g10] was erroneously in the dataset and has been removed - 'Occupation (DKZ 1988)' [p731904_g11] was erroneously in the dataset and has been removed - 'Partner: Occupation (DKZ 1988)' [p731954_g11] was erroneously in the dataset and has been removed - EGP generation syntax was adjusted due to errors in the derivation syntax (particularly classes IVc and V) [p731904_g8, p731954_g8] - German EGP value labels have been corrected [p731904_g8, p731954_g8] - CASMIN [p731802_g2 & p731852_g2]: Class assignment slightly modified - ISCED [p731802_g1 & p731852_g1]: Civil servants of the medium grade are now identifiable - 'SDQ-Scale: Prosocial behaviour' [p67801a_g1] has been corrected to only contain a sum score if all included items are non-missing CohortProfile: - older weighting variables ('Standardized design weight' [weight_design_std] and 'Design weight' [weight_design]) are now deprecated and have been removed - the interview process in parent's interviews does not guarantee unique ids for parents; as "ID_p" therefore has been replaced by "ID_t" and is no longer needed to link datasets, it has been removed from CohortProfile - variable 'Test: survey day 1 (month)' [test1m] has been renamed to [testm_w1] - variable 'Test: survey day 1 (year)' [test1y] has been renamed to [testy_w1] - variable 'Test: survey day 2 (month)' [test2m] has been renamed to [testm_w2] - variable 'Test: survey day 2 (year)' [test2y] has been renamed to [testy_w2] pEducator: - as wave 2 data makes this a panel dataset, the filename has changed from "xEducator" to "pEducator" - 'Further education, successful professional qualification (DKZ 2010)' [e212821_g10] was erroneously in the dataset and has been removed - 'Further education, successful professional qualification (DKZ 1988)' [e212821_g11] was erroneously in the dataset and has been removed pInstitution: - as wave 2 data makes this a panel dataset, the filename has changed from "xInstitution" to "pInstitution" - 'Further education, successful professional qualification (DKZ 2010)' [h212821_g10] was erroneously in the dataset and has been removed - 'Further education, successful professional qualification (DKZ 1988)' [h212821_g11] was erroneously in the dataset and has been removed pTarget: - as wave 2 data makes this a panel dataset, the filename has changed from "xTarget" to "pTarget" - 'SDQ-Scale: prosocial behaviour' [e67801a_g1] has been corrected to only contain a sum score if all included items are non-missing - the scale of variable 'Helps other voluntarily' [e67801i] has been erroneously reversed in generation of 'SDQ-Scale: prosocial behaviour' [e67801a_g1]; this has been fixed spChildCare: - the interview process in parent's interviews does not guarantee unique ids for parents; thus, the identifier in this dataset is no longer "ID_p", but the target person's "ID_t"
