The aim of this paper is to investigate a promising, yet largely unexplored cause of these inconsistencies, namely, differences in how key variables have been conceptualized and operationalized into questionnaire measurement items across this literature. Specifically, by means of a survey experiment with 215 participants from a Swedish university, we formally tested whether alternative operationalizations of two key variables from Protection Motivation Theory—Perceived vulnerability and Perceived severity of a threat—lead to statistically significant differences in mean values across responder groups. Regarding the former variable, we found significant differences between operationalizations focusing on the probability and vulnerability of the threat. Regarding the latter, we found significant differences between whether the target of the consequences of the threat was unclear or clear to respondents, but not between clearly stated targets in terms of individuals and organizations . Overall, therefore, this study contributes to the field by highlighting the importance of conceptual clarity and precision in measuring key variables. It also highlights the potential of survey experiments—an underutilized method in ISP compliance research—for exploring the empirical impact of the different variable operationalizations which currently characterize much of the extant literature.

| 2022 | Which skills? A critical perspective on the skills facilitating the transfer of third-cycle students to knowledge-intensive SMEsabstractThis Research Full Paper relates to public-private innovation ecosystems. This loosely knit form of cooperation allows for beneficial activities such as knowledge transfer, dissemination of novel technology, and recruitment. In these contexts students graduating from third-cycle education should be able to find opportunities for transferring to knowledge-intensive positions in small and medium-sized enterprises (SMEs).(/p)()pHowever, a 3-year study of the reasons why firms approach public organisations within a Europe-wide, public-private innovation ecosystem suggests that students might struggle to find such opportunities. Through a questionnaire provided to all firms approaching the ecosystem we identify recruitment as one of their lowest ranked interests. By interviewing members of the public organisations found in the ecosystem we identify how cooperation is initiated and maintained, and how this influences the opportunities for students to transfer into industry. The results provide nuance to the current emphasis in skill development within third-cycle (engineering) education. It is rarely recognized that fostering technical skill and academic entrepreneurship might not be enough to allow all types and sizes of firms to receive engineering students.Particularly, this study identifies the academic and industrial boundary spanning roles at knowledge-intensive SMEs as important. These roles require a third-cycle education that early on hones skills that typically do not become critical until much later for students that pursue an academic path – e.g., the inter-organisational project management skills necessary to effectively seek research funding or to negotiate goal alignment between organisations. We argue that to allow third-cycle students to practice the finer points of such skills, universities need to evolve more distributed support structures for innovation that integrate in-depth engineering knowledge with innovation skills and have an increased focus on human and social capital.

| 2022 | The effect of perceived organizational culture on employees' information security complianceabstractPurpose This paper aims to investigate the connection between different perceived organizational cultures and information security policy compliance among white-collar workers. Design/methodology/approach The survey using the Organizational Culture Assessment Instrument was sent to white-collar workers in Sweden ( n = 674), asking about compliance with information security policies. The survey instrument is an operationalization of the Competing Values Framework that distinguishes between four different types of organizational culture: clan, adhocracy, market and bureaucracy. Findings The results indicate that organizational cultures with an internal focus are positively related to employees’ information security policy compliance. Differences in organizational culture with regards to control and flexibility seem to have less effect. The analysis shows that a bureaucratic form of organizational culture is most fruitful for fostering employees’ information security policy compliance. Research limitations/implications The results suggest that differences in organizational culture are important for employees’ information security policy compliance. This justifies further investigating the mechanisms linking organizational culture to information security compliance. Practical implications Practitioners should be aware that the different organizational cultures do matter for employees’ information security compliance. In businesses and the public sector, the authors see a development toward customer orientation and marketization, i.e. the opposite an internal focus, that may have negative ramifications for the information security of organizations. Originality/value Few information security policy compliance studies exist on the consequences of different organizational/information cultures.

| 2018 | Detection and Control of Contact Force Transients in Robotic Manipulation Without a Force SensorabstractIn this research, it is shown that robot joint torques can be used to recognize contact force transients induced during robotic manipulation, thus detecting when a task is completed. The approach does not assume any external sensor, which is a benefit compared to the state of the art. The joint torque data are used as input to a recurrent neural network (RNN), and the output of the RNN indicates whether the task is completed. A real-time application for force transient detection is developed, and verified experimentally on an industrial robot. Martin Karlsson, Anders Robertsson, Rolf Johansson 0001 |

| 2018 | Master-Slave Coordination Using Virtual Constraints for a Redundant Dual-Arm Haptic InterfaceabstractProgramming robots for tasks involving force interaction is difficult, since both the knowledge of the task and the dynamics of the robots are necessary. An immersive haptic interface for task demonstration is proposed, where the operator can sense and act through the robot. This is achieved by coupling two robotic systems with virtual constraints such that they have the same coordinates in the operational space disregarding a fixed offset. Limitations caused by the singular configurations or the reach of the robots are naturally reflected to either side as haptic feedback.

| 2018 | Value conflicts and non-compliance: Attitudes to whistleblowing in Swedish organisationsabstractPurpose The purpose of the study is to explore potential value conflicts between information security work and whistleblowing activities by analysing attitudes to whistleblowing among white-collar workers in Swedish organisations. Design/methodology/approach The study is conducted using survey data among (n= 674) Swedish white-collar workers. Statistical analyses are conducted to explore variations in acceptance of whistleblowing and analyse the relationship between acceptance for whistleblowing and information security attitudes and behaviours. Findings The study finds strong support for whistleblowing in both public and private spheres, and by both private and public sector employees. The study also finds stronger acceptance for intra-organisational whistleblowing, while support for external whistleblowing is low. Finally, the study shows that the whistleblowing activities might be perceived as coming in conflict with information security work, even as the support for including whistleblowing functions in information security practices is high. Research limitations/implications With a focus on one country, the study is limited in terms of empirical scope. It is also limited by a relatively small number of respondents and survey items relating to whistleblowing, which in turn affects its explanatory value. However, the study does provide unique new insight into a specific form of “non-compliance”, i.e. whistleblowing, which merits further investigation. Originality/value Few studies exist that combine insights from the fields of whistleblowing and information security research. Thus, this study provides a basis for further investigation into attitudes and behaviours linked to whistleblowing in public and private organisations, as well as attendant value conflicts related to information security management and practice.

| 2018 | Perceptions of organizational culture and value conflicts in information security managementabstractPurpose The purpose of this paper is to investigate the occurrence of value conflicts between information security and other organizational values among white-collar workers. Further, analyzes are conducted of the relationship between white-collar workers’ perceptions of the culture of their organizations and value conflicts involving information security. Design/methodology/approach Descriptive analyses and regression analyses were conducted on survey data gathered among two samples of white-collar workers in Sweden. Findings Value conflicts regarding information security occur regularly among white-collar workers in the private and public sectors and within different business sectors. Variations in their occurrence can be understood partly as a function of employees’ work situations and the sensitivity of the information handled in the organization. Regarding how perceived organizational culture affects the occurrence of value conflicts, multivariate regression analysis reveals that employees who perceive their organizations as having externally oriented, flexible cultures experience value conflicts more often. Research limitations/implications The relatively low share of explained variance in the explanatory models indicates the need to identify alternative explanations of the occurrence of value conflicts regarding information security. Practical implications Information security managers need to recognize that value conflicts occur regularly among white-collar workers in different business sectors, more often among workers in organizations that handle sensitive information, and most often among white-collar workers who perceive the cultures of their organizations as being externally oriented and flexible. Originality/value The study addresses a gap in the information security literature by contributing to the understanding of value conflicts between information security and other organizational values. This study has mapped the occurrence of value conflicts regarding information security among white-collar professionals and shows that the occurrence of value conflicts is associated with work situation, information sensitivity and perceived organizational culture.

| 2017 | Autonomous interpretation of demonstrations for modification of dynamical movement primitivesabstractThe concept of dynamical movement primitives (DMPs) has become popular for modeling of motion, commonly applied to robots. This paper presents a framework that allows a robot operator to adjust DMPs in an intuitive way. Given a generated trajectory with a faulty last part, the operator can use lead-through programming to demonstrate a corrective trajectory. A modified DMP is formed, based on the first part of the faulty trajectory and the last part of the corrective one. A real-time application is presented and verified experimentally.

| 2017 | Measuring employees' compliance - the importance of value pluralismabstractPurpose This paper aims to investigate two different types of compliance measures: the first measure is a value-monistic compliance measure, whereas the second is a value-pluralistic measure, which introduces the idea of competing organisational imperatives. Design/methodology/approach A survey was developed using two sets of items to measure compliance. The survey was sent to 600 white-collar workers and analysed through ordinary least squares. Findings The results suggest that when using the value-monistic measure, employees’ compliance was a function of employees’ intentions to comply, their self-efficacy and awareness of information security policies. In addition, compliance was not related to the occurrence of conflicts between information security and other organisational imperatives. However, when the dependent variable was changed to a value-pluralistic measure, the results suggest that employees’ compliance was, to a great extent, a function of the occurrence of conflicts between information security and other organisational imperatives, indirect conflicts with other organisational values. Research limitations/implications The results are based on small survey; yet, the findings are interesting and justify further investigation. The results suggest that relevant organisational imperatives and value systems, along with information security values, should be included in measures for employees’ compliance with information security policies. Practical implications Practitioners and researchers should be aware that there is a difference in measuring employees’ compliance using value monistic and value pluralism measurements. Originality/value Few studies exist that critically compare the two different compliance measures for the same population. Fredrik Karlsson 0001, Martin Karlsson, Joachim Åström |

| 2016 | Particle filter framework for 6D seam tracking under large external forces using 2D laser sensorsabstractWe provide a framework for 6 DOF pose estimation in seam-tracking applications using particle filtering. The particle filter algorithm developed incorporates measurements from both a 2 DOF laser seam tracker and the robot forward kinematics under an assumed external force. Special attention is paid to modeling of disturbances in the respective measurements, and methods are developed to assist the selection of sensor configurations for optimal estimation performance. The developed estimation algorithm and simulation environment are provided as an open-source, extendable package, written with an intended balance between readability and performance.

| 2015 | Information security culture - state-of-the-art review between 2000 and 2013abstractPurpose – The aim of this paper is to survey existing information security culture research to scrutinise the kind of knowledge that has been developed and the way in which this knowledge has been brought about. Design/methodology/approach – Results are based on a literature review of information security culture research published between 2000 and 2013 (December). Findings – This paper can conclude that existing research has focused on a broad set of research topics, but with limited depth. It is striking that the effects of different information security cultures have not been part of that focus. Moreover, existing research has used a small repertoire of research methods, a repertoire that is more limited than in information systems research in general. Furthermore, an extensive part of the research is descriptive, philosophical or theoretical – lacking a structured use of empirical data – which means that it is quite immature. Research limitations/implications – Findings call for future research that: addresses the effects of different information security cultures; addresses the identified research topics with greater depth; focuses more on generating theories or testing theories to increase the maturity of this subfield of information security research; and uses a broader set of research methods. It would be particularly interesting to see future studies that use intervening or ethnographic approaches because, to date, these have been completely lacking in existing research. Practical implications – Findings show that existing research is, to a large extent, descriptive, philosophical or theoretical. Hence, it is difficult for practitioners to adopt these research results, such as frameworks for cultivating or assessment tools, which have not been empirically validated. Originality/value – Few state-of-the-art reviews have sought to assess the maturity of existing research on information security culture. Findings on types of research methods used in information security culture research extend beyond the existing knowledge base, which allows for a critical discussion about existing research in this sub-discipline of information security.

| 2009 | Simultaneous speculative threading: a novel pipeline architecture implemented in sun's rock processorabstractThis paper presents Simultaneous Speculative Threading (SST), which is a technique for creating high-performance area- and power-efficient cores for chip multiprocessors. SST hardware dynamically extracts two threads of execution from a single sequential program (one consisting of a load miss and its dependents, and the other consisting of the instructions that are independent of the load miss) and executes them in parallel. SST uses an efficient checkpointing mechanism to eliminate the need for complex and power-inefficient structures such as register renaming logic, reorder buffers, memory disambiguation buffers, and large issue windows. Simulations of certain SST implementations show 18% better per-thread performance on commercial benchmarks than larger and higher-powered out-of-order cores. Sun Microsystems' ROCK processor, which is the first processor to use SST cores, has been implemented and is scheduled to be commercially available in 2009.

| 2007 | Conserving Memory Bandwidth in Chip Multiprocessors with Runahead ExecutionabstractThe introduction of chip multiprocessors (CMPs) presents new challenges and trade-offs to computer architects. Architects must now strike a balance between the number of cores per chip versus the amount of on-chip cache and the cost-efficient amount of pin bandwidth. Technology projections indicate that the cost of pin bandwidth would increase significantly and may therefore inhibit the number of processor cores per CMP. Runahead execution is a very promising approach to tolerate long memory latencies. In this paper we study the memory access characteristics of runahead execution. We show that temporal and data dependency aspects of runahead execution makes it possible to conserve bandwidth through the use of smaller cache blocks in the cache. We demonstrate, using execution-driven full system simulation, that our method of fine-grained fetching can obtain significant performance speedups in bandwidth constrained systems but also yield stable performance in systems that are not bandwidth limited.

| 2006 | TMA: a trap-based memory architectureabstractThe advances in semiconductor technology have set the shared-memory server trend towards processors with multiple cores per die and multiple threads per core. We believe that this technology shift forces a reevaluation of how to interconnect multiple such chips to form larger systems.This paper argues that by adding support for coherence traps in future chip multiprocessors, large-scale server systems can be formed at a much lower cost. This is due to shorter design time, verification and time to market when compared to its traditional all-hardware counter part. In the proposed trap-based memory architecture (TMA), software trap handlers are responsible for obtaining read/write permission, whereas the coherence trap hardware is responsible for the actual permission check.In this paper we evaluate a TMA implementation (called TMA Lite) with a minimal amount of hardware extensions, all contained within the processor. The proposed mechanisms for coherence trap processing should not affect the critical path and have a negligible cost in terms of area and power for most processor designs.Our evaluation is based on detailed full system simulation using out-of-order processors with one or two dual-threaded cores per die as processing nodes. The results show that a TMA based distributed shared memory system can perform on par with a highly optimized hardware based design. Håkan Zeffer, Zoran Radovic, Martin Karlsson, Erik Hagersten |

| 2005 | Exploring Processor Design Options for Java-Based MiddlewareabstractJava-based middleware is a rapidly growing workload for high-end server processors, particularly chip multiprocessors (CMP). To help architects design future microprocessors to run this important new workload, we provide a detailed characterization of two popular Java server benchmarks, ECperf and SPECjbb2000. We first estimate the amount of instruction-level parallelism in these workloads by simulating a very wide issue processor with perfect caches and perfect branch predictors. We then identify performance bottlenecks for these workloads on a more realistic processor by selectively idealizing individual processor structures. Finally, we combine our findings on available ILP in Java middleware with results from previous papers that characterize the availibility of TLP to investigate the optimal balance between ILP and TLP in CMPs. We find that, like other commercial workloads, Java middleware has only a small amount of instruction-level parallelism, even when run on very aggressive processors. When run on processors resembling currently available processors, the performance of Java middleware is limited by frequent traps, address translation and stalls in the memory system. We find that SPECjbb2000 differs from ECperf in two meaningful ways: (1) the performance of ECperf is affected much more by cache and TLB misses during instruction fetch and (2) SPECjbb2000 has more memory-level parallelism.

| 2003 | Memory System Behavior of Java-Based MiddlewareabstractIn this paper, we present a detailed characterization of the memory system, behavior of ECperf and SPECjbb using both commercial server hardware and Simics full-system simulation. We find that the memory footprint and primary working sets of these workloads are small compared to other commercial workloads (e.g. on-line transaction processing), and that a large fraction of the working sets are shared between processors. We observed two key differences between ECperf and SPECjbb that highlight the importance of isolating the behavior of the middle tier. First, ECperf has a larger instruction footprint, resulting in much higher miss rates for intermediate-size instruction caches. Second, SPECjbb's data set size increases linearly as the benchmark scales up, while ECperf's remains roughly constant. This difference can lead to opposite conclusions on the design of multiprocessor memory systems, such as the utility of moderate sized (i.e. 1 MB) shared caches in a chip multiprocessor.
