- The present study highlights earning management optimization possibilities to constrain the events of earning management and financial fraud. Our study investigates the existing stock of knowledge and strand literature available on earning management and fraud detection. It aims to review systematically the methods and techniques used by prior research to determine earning management and fraud detection. The results indicate that prior research in earning management optimization is diverged among several techniques and none of these techniques has provided an ideal optimization for earning management. Further, the results reveal that earning management determinants are complex based on the type and size of business entities which complicate the optimization possibilities. The current research brings useful insights for predicting and optimization of earnings management and financial fraud. The present study has significant implications for policymakers, stock markets, auditors, investors, analysts, and professionals.

A History of the Surrealist Novel
- 2023. - 1
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- A History of the Surrealist Novel offers a rich, long, and elastic historiography of the surrealist novel, taking into consideration an abundance of texts previously left out of critical accounts. Its twenty thematically organized chapters examine surrealist prose texts written in French, English, Spanish, German, Greek, and Japanese, from the emergence of the surrealist movement in the 1920s and 1930s, through the post-war and postmodern periods, and up to the contemporary moment. This approach extends received narratives regarding surrealism's geographical locations and considers its transnational movement and modes of circulation. Moreover, it challenges critical biases that have defined surrealism in predominantly masculine terms, and which tie the movement to the interwar or early post-war years. This book will appeal both to scholars and students of surrealism and its legacies, modernist literature, and the history of the novel.

Bokkapitel (refereegranskat)abstract
- The case method provides entrepreneurship educators with great potential to be entrepreneurial and to think outside the box when adjusting the case method for increased entrepreneurial learning. This chapter provides the theoretical background of case-based entrepreneurship education and a debate on context in case teaching in general and the Nordic countries in particular. Further the chapter provides a synopsis and reflections of how the chapters in this book discuss the design and utilization of cases through 2 parts. Part 1 includes theoretical perspectives, discussions, and practical procedures on how the case method and case activities can be reframed and approached in entrepreneurship education in general and for experiential learning in particular. Part 2 contributes with a collection of Nordic entrepreneurship cases with accompanying teaching notes. We believe that this book is of great inspiration for entrepreneurship educators wanting to use the case method in their teaching.

Factors associated with healing failure after early repair of acute, trauma-related rotator cuff tears
- 2023
-
Ingår i: Journal of Shoulder and Elbow Surgery. - : MOSBY-ELSEVIER. - 1058-2746 .- 1532-6500. ; 32:10, s. 2074-2081

Tidskriftsartikel (refereegranskat)abstract
- Background: Healing failure after rotator cuff repair is a challenging problem. Acute, trauma-related tears are considered a separate entity and are often treated surgically. The aim of this study was to identify factors associated with healing failure in previously asymptomatic patients with trauma-related rotator cuff tears treated with early arthroscopic repair. Methods: This study included 62 consecutively recruited patients (23% women; median age, 61 years; age range, 42-75 years) with acute symptoms in a previously asymptomatic shoulder and a magnetic resonance imaging–verified full-thickness rotator cuff tear after shoulder trauma. All patients were offered, and underwent, early arthroscopic repair, during which a biopsy specimen was harvested from the supraspinatus tendon and analyzed for signs of degeneration. Of the patients, 57 (92%) completed 1-year follow-up and underwent assessment of repair integrity on magnetic resonance images according to the Sugaya classification. Risk factors for healing failure were investigated using a causal-relation diagram where age, body mass index, tendon degeneration (Bonar score), diabetes mellitus, fatty infiltration (FI), sex, smoking, tear location regarding integrity of the rotator cable, and tear size (number of ruptured tendons and tendon retraction) were included and analyzed. Results: Healing failure at 1 year was identified in 37% of patients (n = 21). A high degree of FI of the supraspinatus muscle (P = .01), a tear location including disruption of rotator cable integrity (P = .01), and old age (P = .03) were associated with healing failure. Tendon degeneration as determined by histopathology was not associated with healing failure at 1-year follow-up (P = .63). Conclusion: Older age, increased FI of the supraspinatus muscle, and a tear including disruption of the rotator cable increased the risk of healing failure after early arthroscopic repair in patients with trauma-related full-thickness rotator cuff tears.

- Purpose: Acute trauma-related rotator cuff tears are believed to have better healing potential than chronic tears due to less degenerative changes of the tendons. However, the histopathological condition of tendons from trauma-related tears is not well investigated. The purpose of this study was to explore specific histopathological features in tendons from acute trauma-related full-thickness rotator cuff tears and to compare them to findings in tendons from nontraumatic, chronic tears. Methods: In a prospective cohort study, 62 previously asymptomatic patients [14 women, median age 61 years (range 42–75)] with trauma-related full-thickness rotator cuff tears were consecutively included. Arthroscopic repair was performed within 30 (median, IQR 25–37) days after the injury. During surgery, tissue biopsies were harvested from the supraspinatus tendons in 53 (86%) of the patients. In addition, similar biopsies were harvested from 10 patients undergoing surgery for chronic tears without history of trauma. All tissue samples were examined by a well-experienced pathologist under light microscope. Tendon degeneration was determined using the Bonar score whereas immunostaining was used for proliferation (Ki67), inflammation (CD45), apoptosis (p53) and haemosiderin staining to study traces of bleeding. Results: The median (IQR) Bonar score for the acute trauma-related biopsies was 10.5 (7.5–14.5) compared to 11 (5–12.8) for the control group with no statistically significant difference between the groups. No statistically significant between-group difference was found for the inflammatory index whereas tendons from patients with trauma-related full-thickness rotator cuff tears had statistically significantly higher apoptosis [3.1 (0.5–8.9) vs. 0.1 (0–1.5), p = 0.003] and proliferation [4.0 (1.8–6.9) vs. 0.4 (0–2.0), p = 0.001) indices than those undergoing surgery for chronic tears. Positive haemosiderin staining was found in 34% of tissue samples from patients with trauma-related tears compared to 10% in the control group (n.s). Conclusion: This study suggests that there is no difference with regard to degenerative changes between supraspinatus tendons harvested from patients with acute, trauma-related rotator cuff tears and patients with nontraumatic, chronic tears. Level of evidence: II.

Informal Caregivers Experiences with Performing Telemonitoring in Heart Failure Care at Home-A Qualitative Study
- 2022
-
Ingår i: Healthcare. - : MDPI. - 2227-9032. ; 10:7
-
Tidskriftsartikel (refereegranskat)abstract
- Informal caregivers have an important role in caring for family members at home. Supporting persons with a chronic illness such as heart failure (HF) in managing their self-care is reported to be a challenge and telemonitoring has been suggested to be of support. Aim: to explore informal caregivers experiences with performing non-invasive telemonitoring to support persons with HF at home for 30 days following hospital discharge in Norway and Lithuania. Methods: A qualitative explorative study of informal caregivers performing non-invasive telemonitoring using lung-impedance measurements and short message service (SMS). Data was collected using semi-structured interviews with informal caregivers of persons with HF in NYHA class III-IV in Norway and Lithuania. Results: Nine interviews were conducted with informal caregivers of persons with HF who performed non-invasive telemonitoring at home. A sequential process of three categories emerged from the data: access to support, towards routinizing, and mastering non-invasive telemonitoring. Conclusion: Informal caregivers performed non-invasive telemonitoring for the first time in this study. Their experiences were of a sequential process that included access to support from health care professionals, establishing a routine together, and access to nurses or physicians in HF care as part of mastering. This study highlights involving informal caregivers and persons with HF together in the implementation and future research of telemonitoring in HF care.

Self-Care Monitoring of Heart Failure Symptoms and Lung Impedance at Home Following Hospital Discharge: Longitudinal Study
- 2020
-
Ingår i: Journal of Medical Internet Research. - : JMIR PUBLICATIONS, INC. - 1438-8871. ; 22:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Self-care is key to the daily management of chronic heart failure (HF). After discharge from hospital, patients may struggle to recognize and respond to worsening HF symptoms. Failure to monitor and respond to HF symptoms may lead to unnecessary hospitalizations. Objective: This study aimed to (1) determine the feasibility of lung impedance measurements and a symptom diary to monitor HF symptoms daily at home for 30 days following hospital discharge and (2) determine daily changes in HF symptoms of pulmonary edema, lung impedance measurements, and if self-care behavior improves over time when patients use these self-care monitoring tools. Methods: This study used a prospective longitudinal design including patients from cardiology wards in 2 university hospitals-one in Norway and one in Lithuania. Data on HF symptoms and pulmonary edema were collected from 10 participants (mean age 64.5 years; 90% (9/10) male) with severe HF (New York Heart Association classes III and IV) who were discharged home after being hospitalized for an HF condition. HF symptoms were self-reported using the Memorial Symptom Assessment Scale for Heart Failure. Pulmonary edema was measured by participants using a noninvasive lung impedance monitor, the Cardio Set Edema Guard Monitor. Informal caregivers aided the participants with the noninvasive measurements. Results: The prevalence and burden of shortness of breath varied from participants experiencing them daily to never, whereas lung impedance measurements varied for individual participants and the group participants, as a whole. Self-care behavior score improved significantly (P=.007) from a median of 56 (IQR range 22-75) at discharge to a median of 81 (IQR range 72-98) 30 days later. Conclusions: Noninvasive measurement of lung impedance daily and the use of a symptom diary were feasible at home for 30 days in HF patients. Self-care behavior significantly improved after 30 days of using a symptom diary and measuring lung impedance at home. Further research is needed to determine if daily self-care monitoring of HF signs and symptoms, combined with daily lung impedance measurements, may reduce hospital readmissions.

Tidskriftsartikel (refereegranskat)abstract
- Self-care monitoring at home can be a challenge for patients with heart failure (HF). Tools that leverage information and communication technology (ICT), comprise medical devices, or have written material may support their efforts at home. The aim of this study was to describe HF patients experiences and their prioritization of tools that support, or could support, self-care monitoring at home. A descriptive qualitative design employing semi-structured interviews was used with HF patients living at home and attending an HF outpatient clinic in Norway. We used a deductive analysis approach, using the concept of self-care monitoring with ICT tools, paper-based tools, medical devices, and tools to consult with healthcare professionals (HCPs) as the categorization matrix. Nineteen HF patients with a mean age of 64 years participated. ICT tools are used by individual participants to identify changes in their HF symptoms, but are not available by healthcare services. Paper-based tools, medical devices, and face-to-face consultation with healthcare professionals are traditional tools that are available and used by individual participants. HF patients use traditional and ICT tools to support recognizing, identifying, and responding to HF symptoms at home, suggesting that they could be used if they are available and supplemented by in-person consultation with HCPs.

- Virtual reality (VR) provides many exciting new application opportunities, but also present new challenges. In contrast to 360° videos that only allow a user to select its viewing direction, in fully immersive VR, users can also move around and interact with objects in the virtual world. To most effectively deliver such services it is therefore important to understand how users move around in relation to such objects. In this paper, we present a methodology and software tool for generating run-time datasets capturing a user’s interactions with such 3D environments, evaluate and compare different object identification methods that we implement within the tool, and use datasets collected with the tool to demonstrate example uses. The tool was developed in Unity, easily integrates with existing Unity applications through the use of periodic calls that extracts information about the environment using different ray-casting methods. The software tool and example datasets are made available with this paper.

Tidskriftsartikel (refereegranskat)abstract
- With the development of visual digital technologies it has become more common in the social sciences to both use and present research visually. This article explores different strategies for working with and including images in ethnomethodology and conversation analysis (EMCA) transcriptions. The purpose is to investigate how, and if, the ontology of the transcript changes when verbal transcripts become visual transcripts. The article explores what ensures that a transcript is still a transcript and what happens to the reflexive interpretative strategy fundamental to EMCA when new digital technologies make it possible to incorporate images in transcripts. The articles focus is on the social life of methods as well as methodological productivity showing how images can enact different social realities and scientific knowledge.
