- Background: Significant others are important to persons with aphasia. For several reasons they should be involved in speech-language pathology (SLP) services, including acquiring facilitating communicative strategies and receiving support. In order to further adapt SLP services there is a need to know the perceptions and views of the significant others. Little is known about how they perceive changes in communication as well as received SLP services and in what way they want to be involved in these services.Aims: The study aimed to investigate which communicative changes significant others of persons with aphasia had experienced after a stroke event and to what extent these changes were experienced. A further aim was to describe the significant others’ experiences of SLP services and their motivation to participate in these services. Finally, the significant others’ experiences were compared in terms of sex, age, type of relationship, time since stroke onset, and type and severity of aphasia.Methods & Procedures: An 80-item study-specific questionnaire was answered by 173 significant others of persons with aphasia living throughout Sweden (response rate 69%). Of these, 33% were male and 67% female. Mean age was 64.2 years (range 33–87 years) and 85.5% of the participants were a cohabiting partner to a person with aphasia.Outcomes & Results: A total of 64% of participants perceived their conversations as being less stimulating and enjoyable compared with conversations before stroke onset. Aphasia was considered a substantial or very substantial problem by 64%. The participants took on an increased communicative responsibility, and 70% had changed their communicative behaviour in order to facilitate conversations. A total of 75% (n = 130) had met with the SLP of the person with aphasia. Of those, 63% perceived their own support from SLP services to be adequate; 87% considered language ability training as the most important SLP service. Type and severity of aphasia were especially related to the communicative experiences of the participants and their motivation to be involved in SLP services.Conclusions: The substantial decrease from pre- to post-stroke regarding enjoyment and meaningfulness of conversations suggests the need to further improve SLP services in order to help the people in question communicate at an optimal level. We suggest that clinicians should put more emphasis on explaining the benefits and availability of different kinds of aphasia rehabilitation services, such as functional communication training and communication partner training in addition to language ability training.

Tidskriftsartikel (refereegranskat)abstract
- Background: Changes in the everyday life and health of the significant others (SOs) of people living with stroke sequalae have been widely investigated. However, information regarding the frequency of the changes in daily life and the variables most associated with these perceived life changes is limited. Aims: To examine the extent to which SOs of persons with aphasia (PWAs) experience changes in everyday life and health after the stroke event and how they evaluate these changes and to identify which variables are associated with these perceived life changes. Methods & Procedures: A study-specific questionnaire about perceived changes in everyday life and health was completed by 173 SOs of PWAs living in Sweden (response rate 67.8%). The items concerned the SO’s working and financial situation, leisure time and social life, relationship with the PWA, household work and responsibility, and health and quality of life. Outcomes & Results: The everyday life and health of the SOs were greatly affected by the stroke event. The changes the SOs experienced were mainly appraised negatively. The relationships with the PWA and immediate family were least affected by the stroke. The perceived existence and severity of physical, cognitive, and language impairments of the PWA were the variables most strongly associated with the everyday life situation of the participants. The sex and age of the participants and the nature of the relationship with the PWA were only marginally associated with the experience of the situation. Conclusions: SOs’ perceptions of the PWA’s stroke-related disabilities and need for assistance may be a key factor in identifying SOs who may require support and guidance to help them cope with their new life situation.

Does Investor Recognition Predict Excess Returns?
- 2024

Ingår i: SSRN Electronic Journal. - : Elsevier BV. - 1556-5068.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- We test Merton's (1987) hypothesis using individual level stockholdings of Swedish investors. Controlling for size and other factors, we find that lower levels of investor recognition lead to greater future excess returns. Positive (negative) changes in investor recognition are followed by lower (higher) excess returns. The effect of investor recognition is more pronounced for young firms. We demonstrate that investor recognition is conditionally priced.

Investor Recognition and the Long-Run Performance of Repurchases
- 2004
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Theory suggests that firms with lower investor recognition should provide investors with higher returns. Using U.S. data we document a strong negative relationship between changes in investor recognition and asset returns. We demonstrate that investor recognition is a priced factor in asset returns different from the traditional ones. Undertaking a repurchase significantly reduces the firm's investor recognition. Accounting for changes in investor recognition reduces the abnornlal performance of firms undertaking a repurchase by 1.4% over one year.

Konferensbidrag (refereegranskat)abstract
- Recent years have seen an increasing trend towards the development of Discrete Event Simulation (DES) platforms to support cloud computing related decision making and research. The complexity of cloud environments is increasing with scale and heterogeneity posing a challenge for the efficient management of cloud applications and data centre resources. The increasing ubiquity of social media, mobile and cloud computing combined with the Internet of Things and emerging paradigms such as Edge and Fog Computing is exacerbating this complexity. Given the scale, complexity and commercial sensitivity of hyperscale computing environments, the opportunity for experimentation is limited and requires substantial investment of resources both in terms of time and effort. DES provides a low risk technique for providing decision support for complex hyperscale computing scenarios. In recent years, there has been a significant increase in the development and extension of tools to support DES for cloud computing resulting in a wide range of tools which vary in terms of their utility and features. Through a review and analysis of available literature, this paper provides an overview and multi-level feature analysis of 33 DES tools for cloud computing environments. This review updates and extends existing reviews to include not only autonomous simulation platforms, but also on plugins and extensions for specific cloud computing use cases. This review identifies the emergence of CloudSim as a de facto base platform for simulation research and shows a lack of tool support for distributed execution (parallel execution on distributed memory systems).

Tidskriftsartikel (refereegranskat)abstract
- This paper outlines the main idea and approach of the H2020 ASSISTANT (LeArning and robuSt deciSIon SupporT systems for agile mANufacTuring environments) project. ASSISTANT is aimed at the investigation of AI-based tools for adaptive manufacturing environments, and focuses on the development of a set of digital twins for integration with, management of, and decision support for production planning and control. The ASSISTANT tools are based on the approach of extending generative design, an established methodology for product design, to a broader set of manufacturing decision making processes; and to make use of machine learning, optimisation, and simulation techniques to produce executable models capable of ethical reasoning and data-driven decision making for manufacturing systems. Combining human control and accountable AI, the ASSISTANT toolsets span a wide range of manufacturing processes and time scales, including process planning, production planning, scheduling, and real-time control. They are designed to be adaptable and applicable in a both general and specific manufacturing environments.

Bokkapitel (refereegranskat)abstract
- The complexity of computing along the cloud-to-edge continuum presents significant challenges to ICT operations and in particular reliable capacity planning and resource provisioning to meet unpredictable, fluctuating, and mobile demand. This chapter presents a high-level conceptual overview of RECAP—an architectural innovation to support reliable capacity provisioning for distributed clouds—and its operational modes and functional building blocks. In addition, the major design concepts informing its design—namely separation of concerns, model-centricism, modular design, and machine learning and artificial intelligence for IT operations—are also discussed.

Pressure-controlled versus manual facemask ventilation for anaesthetic induction in adults : A randomised controlled non-inferiority trial
- 2023
-
Ingår i: Acta Anaesthesiologica Scandinavica. - : John Wiley & Sons. - 0001-5172 .- 1399-6576. ; 67:10, s. 1356-1362

Tidskriftsartikel (refereegranskat)abstract
- Background: Pressure-controlled face mask ventilation (PC-FMV) with positive end-expiratory pressure (PEEP) after apnoea following induction of general anaesthesia prolongs safe apnoea time and reduces atelectasis formation. However, depending on the set inspiratory pressure, a delayed confirmation of a patent airway might occur. We hypothesised that by lowering the peak inspiratory pressure (PIP) when using PC-FMV with PEEP, confirmation of a patent airway would not be delayed as studied by the first return of CO2, compared with manual face mask ventilation (Manual FMV).Methods: This was a single-centre, randomised controlled non-inferiority trial. Seventy adult patients scheduled for elective day-case surgery under general anaesthesia with body mass index between 18.5 and 29.9 kg m(-2), American Society of Anesthesiologists (ASA) classes I-III, and without anticipated difficult FMV, were included. Before the start of pre-oxygenation and induction of general anaesthesia, participants were randomly allocated to receive ventilation with either PC-FMV with PEEP, at a PIP of 11 and a PEEP of 6 cmH(2)O or Manual FMV, with the adjustable pressure-limiting valve set at 11 cmH(2)O. The primary outcome variable was the number of ventilatory attempts needed until confirmation of a patent airway, defined as the return of at least 1.3 kPa CO2.Results: The return of >= 1.3 kPa CO2 on the capnography curve was observed after mean +/- SD, 3.6 +/- 4.2 and 2.5 +/- 1.9 ventilatory attempts/breaths with PC-FMV with PEEP and Manual FMV, respectively. The difference in means (1.1 ventilatory attempts/breaths) had a 99% CI of similar to 1.0 to 3.1, within the accepted upper margin of four breaths for non-inferiority.Conclusion: Following induction of general anaesthesia, PC-FMV with PEEP was used without delaying a patent airway as confirmed with capnography, if moderate pressures were used.
