Institutional Logics and Their Influence on Enterprise Architecture Adoption

Enterprise architecture adoption (EAA), often ironically known as “ineffective adoption,” is frequently marked by poor utilization and signals of failure. To date, comprehensive examinations of which factors influence EAA are lacking. This study aims to address this knowledge gap. The paper uses an interpretive multiple case-study approach using an institutional theory lens to conduct the research. The findings show that three institutional logics dominate EAA: managerialism, professionalism, and user logic. These logics drive stakeholder activities and behaviors and ultimately influence EAA processes and outcomes. The paper contributes to the literature by explaining how these three logics influence the adoption process. Practitioners will be able to use the logics discussed in this study to assess and prevent potential challenges to adoption by carefully examining the stakeholder behaviors and activities embedded in these logics.© 2019 Taylor & Francis.

Essays on Asset Pricing Factor Models

This dissertation investigates the utilization of factor models to measure performance in corporate bond markets, identifies an optimal factor model for corporate bond returns, and finally provides a comprehensive analysis of factor pricing and market integration across asset classes. Chapter 1 introduces the main concepts and delivers an overview of the following chapters. Chapter 2 seeks to answer the question "which factor model do investors in corporate bonds use?" by tracking investors' decisions to invest in actively managed corporate bond mutual funds with a revealed preference approach. The main result is that all bond factor models are dominated by the simple Sharpe ratio and Morningstar ratings. For all major corporate bond mutual fund styles, the Sharpe ratio explains fund flows better than alphas from bond factor models. Since the Sharpe ratio (and to some extent also Morningstar ratings) can be easily manipulated in bond markets, these findings have potentially severe implications for all market participants. Going a step further, Chapter 3 addresses the following important questions, from both an academic and a practitioner's perspective: What are important drivers of corporate bond returns? What should be a benchmark model for pricing and investing in corporate bond markets? The central finding is that factors related to carry, duration, equity momentum, and the term structure are the most important risk factors in corporate bond markets. From a large set of factor candidates for corporate bond returns, we condense an optimal model with a two-step approach. First, we filter out factors that do not systematically move bond prices. Second, we use a Bayesian model selection approach to determine the optimal, parsimonious model. Many prominent factors do not move prices, or are redundant. We document the new model's good performance compared to that of existing models in time-series and cross-sectional tests and analyze the economic drivers of the factors. While Chapter 2 and Chapter 3 focus on corporate bonds, the study conducted in Chapter 4 extends the understanding to a bigger picture of factor pricing and market integration across asset classes. Factor models specializing in one asset class have limited pricing power for other asset classes. Thus, we reject perfect market integration. However, an optimal integrated factor model across asset classes can effectively characterize the returns of multiple asset classes and provide a useful benchmark for multi-asset, multi-factor investing. The optimal model includes several equity and corporate bond factors, suggesting the presence of multiple systematic return drivers. Despite this, there appears to be some degree of cross-market linkages, as the optimal model does not require factors from all asset classes. Finally, Chapter 5 concludes and outlines possible future directions for research

Enterprise Architecture and Organizational Reform: A Project Debrief

This paper studies on how enterprise architecture (EA) is used as a tool to assist organizational reform. In particular, we examine how institutional factors influencing organization change process through an EA project. We conduct a qualitative case study and use institutional theory as a lens to analyze data from an organization. This analysis offers insights about how exogenous and endogenous factors influence organizational change, and how organizational structures get shaped, diffused, and institutionalized. Our study provides understanding how stakeholders are involved in project activities in multiple levels and phases of the institutionalization process; namely innovation phase, theorization phase, diffusion phase, and institutionalization phase

Digital Strategy in Information Systems : A Literature Review and an Educational Solution Based on Problem-Based Learning

In recent years, there has been a considerable amount of information systems (IS) research on digital strategy. However, it is not clear how digital strategy is taught in higher education. To investigate this issue, we conducted a literature review on digital strategy in the IS field and IS education. We then developed a digital strategy course using the problem-based learning (PBL) approach with constructivism as a theoretical lens. The research contributes to the literature by illustrating the key differences between digital strategy and IT/IS strategy while providing insight into the dimensions of digital strategy. These dimensions are digital strategy environments, digital strategy visions, digital strategy approach, digital strategy capabilities, digital strategy stakeholders, and digital strategy challenges. We then used these dimensions as inputs to design the digital strategy course. We contribute to IS education by proposing a meta-requirement for the digital strategy course based on the PBL approach and provide an example of the course syllabus.©2022 by the Information Systems & Computing Academic Professionals, Inc.

Understanding Cyberprivacy: Context, Concept, and Issues

Cyberprivacy has become one of the most worrisome issues in the age of digitalization, as data breaches have increased at an alarming rate, and the development of technology has changed privacy norms themselves. Thus, maintaining cyberprivacy is important for both academia and practitioners. However, the literature on cyberprivacy is fragmented, since the topic is multidisciplinary and often confused with cybersecurity and data privacy. In this study, we seek to understand cyberprivacy by conducting a comprehensive literature review and analyzing 79 selected articles on the topic between 2008 and 2021. Our analysis shows that there are eight contexts associated with cyberprivacy. We proposed concepts on cyberprivacy from different views and highlighted four issues related to cyberprivacy for future consideration. Taken together, the knowledge on cyberprivacy, its challenges and its practices does not seem to accumulate. Consequently, there is a need for more targeted research on the topic to cover different contexts

Institutional perspectives on the process of enterprise architecture adoption

Organizations often adopt enterprise architecture (EA) when planning how best to develop their information technology (IT) or businesses, for strategic management, or generally for managing change initiatives. This variety of different uses affects many stakeholders within and between organizations. Because stakeholders have dissimilar backgrounds, positions, assumptions, and activities, they respond differently to changes and the potential problems that emerge from those changes. This situation creates contradictions and conflicts between stakeholders that may further influence project activities and ultimately determine how EA is adopted. In this paper, we examine how institutional pressures influence EA adoption. Based on a qualitative case study of two cases, we show how regulative, normative, and cognitive pressures influence stakeholders’ activities and behaviors during the process of EA adoption. Our contribution thus lies in identifying roles of institutional pressures in different phases during the process of EA adoption and how it changes overtime. The results provide insights into EA adoption and the process of institutionalization, which help to explain emergent challenges in EA adoption.fi=vertaisarvioitu|en=peerReviewed

Building forecast maps of water quaůity for main rivers and canals in Tien Giang province, Vietnam

This study aims to enhance the mapping of forecast for water quality assessment in Mekong Delta provinces. The data from 32 sites from main rivers and canals in an area of around 2,482 km2 in Tien Giang Province, Vietnam, were used for calculation and mapping. The ArcGIS 9.3 software, Inverse Distance Weighting (IDW) interpolation method, hydrologic data, and water quality parameters in March (2010-2014) were applied to build the maps showing 2020 water quality predictions for main rivers and canals in Tien Giang Province. The estimation was based on the Water Quality Index (WQI) with 6 parameters such as pH, total suspended solid (TSS), dissolved oxygen (DO), biochemical oxygen demand (BOD), total nitrogen (T_N), and coliform. The results showed that water quality in the studied area in dry season will not be improved by the year 2020. The finding could be a scientific reference for the selection of effective approaches to improve water quality in main rivers and canals in Tien Giang Province
