- We consider TCP performance for cloud services in 5G cellular networks and show that edge clouds offer the highest throughput, but that further improvements still are possible. To this end we devise a concept where edge clouds connected directly to the radio access network can increase their transmission rates by relying on the built in re-transmissions (through quality of service features) and on the built in user fairness (through per-user buffers and scheduler policies). We use numerical examples from measurements in real networks to demonstrate that the concept is efficient and significantly improves the effective throughput beyond what placement alone can do, and we also outline possible further improvements.

- We consider bottlenecks of TCP throughput in scenarios with edge clouds and 5G cellular networks. By numerical examples from measurements in real networks, we show that edge clouds indeed improve throughput but that several, non-negligible bottlenecks remain. We therefore devise a concept where edge clouds connected directly to the radio access network can increase their transmission rates by relying on built in retransmissions (through quality of service features) and on the built in user fairness (through per-user buffers and scheduler policies). We then return to the numerical examples and show that our solution provides substantial gains and we conclude by identifying and discussing the remaining bottlenecks and the potential of an improved protocol.

The relation between office type and workplace conflict : A gender and noise perspective
- 2015

- This exploratory study aimed to investigate the impact of the office design on workplace conflicts, with a special attention to noise in the office. A gender perspective was applied. The sample consisted of 5229 employees from the Swedish Longitudinal Occupational Survey of Health 2010 (SLOSH), working in different office types. In the multivariate analysis office type was used as the explanatory variable with adjustments for age, supervisory position and labour market sector. Analysis stratified for gender was used. Among women a significant impact of office type per se on workplace conflicts was found, but not among men. For women several office types differed significantly from the cell-office with regard to prevalence of conflicts during the past two years, but for men only the combi-office differed from the cell-office. Noise had an impact on workplace conflicts, but is not the only explanatory factor since the effect of office type remained also after adjustment for noise in multivariate analyses. Other environmental factors inherent in the office type might thus explain the occurrence of conflicts.

Expert guidance for environmental compensation is consistent with public preferences - Evidence from a choice experiment in Sweden
- 2022

- Public acceptance of environmental compensation (offsetting) as a mechanism to address negative human impacts on biodiversity and ecosystem services is critical. Given that "in-kind/on-site" compensation is rarely possible, proposals must address trade-offs with respect to design. We measure Swedish citizens' support for compensation and analyze preferences for design attributes based on a choice experiment in which respondents choose between various compensation alternatives to address the hypothetical loss of green space due to urban development. We find citizens' support for compensation is high, but the activity causing the damage affects acceptance. Our model suggests that several design attributes affect choice but size of the compensation area was valued highest, both in relative and absolute terms. Further, our results suggest that compensation should be primarily focused on creating or improving biodiversity and nature values in order to be in line with public preferences. Additionally, choice depends on interactions between attributes: a larger compensation site matters more when it is relatively further away; and the importance of size and distance from damage depends on whether compensation type focuses on nature or recreational values. Observable characteristics such as a respondent's age, income and education affect compensation design preferences, but perceptions and previous experiences have the largest effect on choice. Our findings suggest that public preferences are consistent with many of the general recommendations found in guidance documents, but local context may argue for alternative priorities with respect to certain species, habitats, and/or the wellbeing of certain groups. To engender broad support, compensatory offsets will need to balance scientific rigor with transparent involvement of the public.

Om organisering av det regenerativa arbetet : samtal om roll, process och interaktivt meningsskapande
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The focal point of this thesis is an interest in the phenomena of regenerative work, which is a work that has the potential of recreating and developing human resources and energy. The aim is to make a contribution, by presenting a supplementary perspective, to this area of research by considering regenerative work through a process perspective where the centre of interest is transferred from being a question of what to a question of how? The guiding research question is as follows: How could the organizing processes of regenerative work be understood? - more specifically - through an interactive approach the purpose is to describe, analyze and understand those everyday processes that have implications for regenerative work. This general inquiry took place at a number of wards/departments at a hospital in southern Sweden. Above all, the empirical focus concentrated on two specific occurrences: (1) an implementation of a new work model at the various wards/departments and (2) the function of the ward managers and their work situation. Empirical material was collected in collaboration with assistant nurses, registered nurses and ward managers through forum dialogues, interviews and observations. Narratives as formation of knowledge are a significant tool that constitutes an important foundation of this thesis. The chain of events and actions of complex processes are thus interpreted and understood by means of using narratives as a research device. The narrative form was also a source of inspiration for a large portion of the results presentation. The comprehension of the construction of experiences that may be related to regenerative work must be interpreted and understood beyond an individualistic perspective. Overconfidence in rules and routines, and a predetermined execution of the work proved also to be problematic in a complex and symbolically charged reality. Consequently, regenerative work must be understood in the light of a reality/world that consists of regularities and irregularities as well as predictability and unpredictability. It is in the complexity of such worlds, actors are required to interpret what their work/assignment is about and to carry it out satisfactory and to the best of their ability. Hence, two crucial questions are derived: How is the work/assignment interpreted? Are their prerequisites in the organization enabling and supporting good performances? In conclusion, these two questions are interconnected and discussed further in view of local basic conditions for conversation and action as well as leadership in terms of organizing for sensemaking.

Analytic or holistic? A study about how to increase the agreement in teachers’ grading

Tidskriftsartikel (refereegranskat)abstract
- In Sweden, grades are used for selection to upper-secondary school and higher education, even though agreement in teachers’ grading is low and the selection therefore potentially unfair. Furthermore, measures taken to increase the agreement have not been successful. This study has explored how to increase agreement in teachers’ grading by comparing analytic and holistic grading. Teachers (n = 74) have been randomly assigned to two different conditions (i.e. analytic or holistic grading) in either English as a foreign language (EFL) or mathematics. Findings suggest that analytic grading is preferable to holistic grading in terms of agreement among teachers. The effect was stronger and statistically significant in EFL, but could be observed in mathematics as well. However, teachers in the holistic conditions provided more references to criteria in their justifications, whereas teachers in the analytic conditions to a much larger extent made references to grade levels without specifying criteria.

Tidskriftsartikel (refereegranskat)abstract
- Introduction A growing number of parents are navigating parenthood influenced by medical complexity and technological dependency as the group of children with long-term tracheostomy grows. However, little is known regarding the parental experiences of parenthood for this heterogeneous group of children now surviving through infancy and intensive care.Objective This study aimed to analyze how parents of children who have received a tracheostomy adapted to parenthood.Methods Interviews were conducted and analyzed following a constructivist grounded theory approach. Ten parents of seven children living with a tracheostomy in Sweden were recruited via the long-term intensive care unit (ICU).Results The core variable of parenthood "Stuck in survival" was explained by two categories and six subcategories. The category "Unaddressed previous history" describes the experiences from being in the ICU environment and how the parents are not able, due to insufficient time and resources, to address these stressful experiences. The category "Falling through the cracks of a rigid system" describes how the parents found themselves and their children to be continuously ill-fitted in a medical system impossible to adapt to their needs and situation. Parents placed the starting point of parenthood with the birth of the child, whilst the tracheotomy only constituted a turning point and would lead to the loss of any previously held expectations regarding parenthood.Conclusion This study identified a previously undescribed period prior to tracheostomy placement, which may have long-lasting effects on these families. The care provided in ICUs following the birth of a child who will require tracheostomy may not be tailored or adapted to accommodate the needs of these families leading to long-lasting effects on parenthood.
