These phenomena of IS use are typically set in multi-leveled, dynamic, and complex contexts that lend explanation to the non-positivist tradition in IS research. However, limited methodological options exist to make predictions. In this research, we propose stratified agent-based modeling, a step-by-step approach that enables prediction in non-positivist paradigms. Drawing upon the critical realist philosophy of science, which suggests ontological stratification and assumes open systems, we adopt a retroduction-based explanation formation and agent-based modeling to simulate different potential states of a complex system. The critical step in combining critical realism with agent-based modeling involves identifying and codifying the underlying generative mechanisms (i.e., causal powers) into various components of the agent-based model. We propose four steps toward prediction under the critical realist paradigm: (1) capturing the phenomenon, (2) identifying the generative mechanism, (3) building the agent-based model, and (4) simulating states of the system. We present an exemplar of our proposed approach that investigates the effectiveness of strategies to combat malicious content propagation in social networks.","PeriodicalId":50178,"journal":{"name":"Journal of Information Technology","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this potential, research analysing such datasets often struggles to construct novel theoretical insight. This paper argues that holistically incorporating temporality enhances data collection and data analysis, thereby facilitating process theory construction from SMTD. Recommendations to integrate temporality are outlined in the proposed Temporal Dynamics Framework and Methodology (TDFM). We apply the TDFM to investigate the temporal dynamics of mental health discourse on Twitter (now X) across different phases of the COVID-19 pandemic, theoretically framed in the context of innate psychological needs satisfaction. The findings reveal dynamic shifts in social media use, indicating that different phases of the pandemic triggered dynamic shifts in the needs motivating, and being motivated by, social media use. This illustrative case reflectively evaluates the usefulness of the TDFM in contextualising SMTD collection, analytical strategies, and process theory construction by incorporating a dynamic perspective on time.","PeriodicalId":50178,"journal":{"name":"Journal of Information Technology","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This development has raised expectations that a firm’s chief information officer (CIO) will take a more strategic role, including innovation leadership and digital exploration. In this study, we argue from an upper echelons perspective that CIOs’ career variety and role tenure are critical in shaping the extent to which firms explore digital technologies in their patent portfolio, i.e., digital exploration. We expect a U-shaped relationship between CIO career variety and digital exploration, and an inverted U-shaped relationship between CIO role tenure and digital exploration. We test our conceptual model using a cross-industry panel of U.S. firms. As predicted, the results show high digital exploration for low and high career variety, and low digital exploration for moderate career variety, i.e., a U-shape. Conversely, they show low digital exploration for low and high role tenure, and high digital exploration for moderate role tenure, i.e., an inverted U-shape. These insights indicate that CIOs do become strategic leaders in exploring and shaping digital innovation.","PeriodicalId":50178,"journal":{"name":"Journal of Information Technology","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140978756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To provide scholars with an overview of the literature, we performed a systematic qualitative review of the IS literature. The goal of our review was to identify the antecedents and consequences of trust in technology that have received frequent empirical support, as well as those for which the evidence is not yet conclusive. To that end, we curated a glossary of unique construct terms and summarized the results of 241 relationships tested in 62 empirical research articles (both quantitative and qualitative) from the AIS “Basket of Eight” journals. From these, we identified 62 unique relationships: 22 are well-supported, six are supported by suggestive evidence, and 34 have received little support. These relationships summarize what is well-known and less well-known within the literature. By taking stock, we prepare a path for future research on the phenomenon of trust in the context of emerging technologies (e.g., artificial intelligence, blockchain). We conclude the paper with opportunities and directions for future research.","PeriodicalId":50178,"journal":{"name":"Journal of Information Technology","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140812515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Untuk mengatasinya, diperlukan ketelitian yang hati-hati dan waktu yang cukup untuk menyusun jadwal pelajaran. Algoritma genetika muncul sebagai pilihan yang tepat untuk menangani penjadwalan mata pelajaran di sekolah karena kemampuannya menyelesaikan masalah multi-kriteria dan multi-objektif yang terinspirasi dari evolusi biologis. Konsep algoritma genetika dapat diterapkan secara efektif dalam konteks penyusunan jadwal di institusi pendidikan. Penelitian ini menggunakan metodologi kuantitatif dan menerapkan metode pengembangan sistem Rapid Application Development (RAD). Penggunaan algoritma genetika dalam penyusunan jadwal mata pelajaran, seperti yang ditunjukkan dalam penelitian ini, dapat memberikan manfaat bagi lembaga pemasyarakatan yang sebelumnya melakukan proses penyusunan jadwal secara manual.
