- The understanding of Earth's biodiversity depends critically on the accurate identification and nomenclature of species. Many species were described centuries ago, and in a surprising number of cases their nomenclature or type material remain unclear or inconsistent. A prime example is provided by Elephas maximus, one of the most iconic and well-known mammalian species, described and named by Linnaeus (1758) and today designating the Asian elephant. We used morphological, ancient DNA (aDNA), and high-throughput ancient proteomic analyses to demonstrate that a widely discussed syntype specimen of E.maximus, a complete foetus preserved in ethanol, is actually an African elephant, genus Loxodonta. We further discovered that an additional E.maximus syntype, mentioned in a description by John Ray (1693) cited by Linnaeus, has been preserved as an almost complete skeleton at the Natural History Museum of the University of Florence. Having confirmed its identity as an Asian elephant through both morphological and ancient DNA analyses, we designate this specimen as the lectotype of E.maximus. The mass spectrometry proteomics data have been deposited in the ProteomeXchange Consortium with the data set identifier PXD000423.

Why do you control? The concept of control purpose and its implications for is project control research
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Existing IS project control research primarily draws on agency theory to conceptualize control, relating control closely to aligning behaviors of self-interested controllees with organizational objectives. Recent studies in neighboring disciplines, however, suggest that the agency view of control is too narrow to fully understand control activities. Informed by these studies as well as drawing on stewardship and coordination theory, we introduce the concept of control purpose to the IS literature. We define this concept as the intentions underlying the controller's control activities, and distinguish between appropriation-And coordination-oriented controls. To evaluate the control purpose concept, we conduct a secondary analysis of 21 IS project control case studies. Results show that, despite their stated agency focus, most studies report on controls addressing both appropriation concerns and coordination requirements. On this basis, we discuss two potential research areas, knowledge management and control dynamics, where the control purpose concept can offer novel insights.

Moving IS Project Control Research into the Digital Era: The "Why" of Control and the Concept of Control Purpose
- 2019

Tidskriftsartikel (refereegranskat)abstract
- In this research commentary, we argue that the current digital era compels a reconsideration and problematization of research on information systems (IS) project control. IS projects are key to the pursuit of digital innovation and transformation activities, and the control of IS projects is central to creating and capturing value from these activities. However, IS project control research has not kept pace with current developments in the digital era. Specifically, we find that existing research has been dominated by an underlying agency theory perspective, which is not attuned to salient aspects of current control settings, such as digital innovation initiatives, and thus restricts our understanding of IS project control. To address this shortcoming, we problematize core assumptions underlying existing IS project control research and draw on stewardship theory to present an alternative set of assumptions complementing the prevalent agency theory perspective; introduce the concept of control purpose (why); offer empirical support for its conceptual distinction between value-appropriation and value-creation control purposes; and develop a research agenda that helps move IS project control research into the digital era.
