Mediation analysis is a statistical method that aims to isolate the causal mechanisms that make an intervention work in a given context. We combined data from a cluster randomized control trial and a mixed-methods process evaluation. We developed two causal models following our hypotheses of how the intervention was intended to work through mechanisms at health centres to improve health outcomes in the community. In adjusted analyses, there was evidence of an effect of the intervention on some health centre mechanisms; however, these did not lead to improvements in community health outcomes. We discuss the practical and epistemological challenges encountered when using mediation analysis to evaluate a complex intervention. These findings will inform future evaluations.

The classical response to this need is anonymization, i.e., sanitizing the information that, directly or indirectly, can allow users’ re-identification. Among the various approaches, <math><mi>k</mi></math>-anonymity provides a simple and easy-to-understand protection. However, <math><mi>k</mi></math>-anonymity is challenging to achieve in a continuous stream of data and scales poorly when the number of attributes becomes high.In this paper, we study a novel anonymization property called <math><mi>z</mi></math>-anonymity that we explicitly design to deal with data streams, i.e., where the decision to publish a given attribute (atomic information) is made in real time. The idea at the base of <math><mi>z</mi></math>-anonymity is to release such attribute about a user only if at least <math><mrow><mi>z</mi><mo>−</mo><mn>1</mn></mrow></math> other users have exposed the same attribute in a past time window. Depending on the value of <math><mi>z</mi></math>, the output stream results <math><mi>k</mi></math>-anonymized with a certain probability. To this end, we present a probabilistic model to map the <math><mi>z</mi></math>-anonymity into the <math><mi>k</mi></math>-anonymity property. The model is not only helpful in studying the <math><mi>z</mi></math>-anonymity property, but also general enough to evaluate the probability of achieving <math><mi>k</mi></math>-anonymity in data streams, resulting in a generic contribution.</div>","PeriodicalId":19964,"journal":{"name":"Performance Evaluation","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49901370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluator–client relationship is critical in this respect, since it contains inherent tensions due to the necessity for independent assessments alongside requirements for increased responsiveness to clients’ interests. Despite this distinct relationship, the client perspective has only recently received attention in research. This article presents findings from a survey among US evaluation clients and compares these to existing evidence from Switzerland. Unlike previous studies, we distinguish between constructive and destructive client influences. We show that professional experience and client familiarity with evaluation standards increase the likelihood of constructive influences aimed at improving evaluation results. Nevertheless, the findings indicate that dissatisfaction with an evaluation increases client’s attempts at influence that may be destructive. By discussing both motives behind influence and potential preventive measures, this article seeks to contribute to the increased social impact of policy evaluations.","PeriodicalId":19964,"journal":{"name":"Performance Evaluation","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76584634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
