Towards New Levels of Creating/Improving and Understanding Value in Swedish Municipalities : A Review of Research on Understanding and Creating Value in Municipal Quality Development by Qualitative Approaches (and Co-Creation)
- 2017
-
Konferensbidrag (refereegranskat)abstract
- PurposeQuality management and Lean initiatives are currently widespread in the Swedish municipal sector. It is also made clear that all Lean initiatives should be initiated to benefit the customer and not for internal organizational reasons. However, the practices currently used for understanding value creation in the municipalities tend to focus heavily on the use of numerical, quantitative approaches. In sharp contrast, the growing field of, for example, design thinking argue that qualitative approaches are key when it comes to getting closer to the citizens, establishing new levels of understanding and thereby inspiring new and better solutions. In sum, it seems likely that municipalities are struggling with developing quality due to relying, in too one-sided on the use of quantitative rather than qualitative approaches to understand and spark new levels of value creation. The purpose of this paper is to contribute with a review of research concerning qualitative approaches for understanding and co-creating value in municipal quality development. Methodology/Approach The paper is based on a literature review. Findings The paper provides an overview of previous research concerning practices for evaluating and understanding value creation in the context of a municipal quality development. Value of the paperThis overview is of value for practitioners within the context, as well as researchers that wants to contribute within this area.

Cooperative Lewis Acids and Aminocatalysis
- 2017
-
Ingår i: Chiral Lewis Acids in Organic Synthesis. - Weinheim, Germany : Wiley-Blackwell. ; , s. 345-374
-
Bokkapitel (refereegranskat)abstract
- This chapter describes the cooperative strategy of combining metal catalyst activation with aminocatalysis, with a focus on the metal acting as a Lewis acid catalyst. It gives examples where the metal catalyst promotes the reactivity of different substrates by the formation of reactive intermediates. These intermediates can act either as electrophiles or nucleophiles, which in turn can couple with nucleophilic enamine or electrophilic iminium intermediates formed between the carbonyl compounds and aminocatalyst. The chemical transformation ensues via the merging of the enamine and π‐allyl‐Pd complex via asymmetric counteranion‐direct catalysis (ACDC). Subsequently, several groups reported different co‐catalytic systems and chemical strategies for the α‐allylic alkylation of aldehydes and ketones. Cordova and coworkers reported the first example where iminium activation catalysis is combined with metal catalyst activation cooperatively. The stratagem was demonstrated for the catalytic enantioselective conjugate silyl addition to α,β‐unsaturated aldehydes.

Sustainable Design for the Direct Fabrication and Highly Versatile Functionalization of Nanocelluloses
- 2017

Ingår i: Global Challenges. - Weinheim : Wiley. - 2056-6646. ; 1:7

Tidskriftsartikel (refereegranskat)abstract
- This study describes a novel sustainable concept for the scalable direct fabrication and functionalization of nanocellulose from wood pulp with reduced energy consumption. A central concept is the use of metal-free small organic molecules as mediators and catalysts for the production and subsequent versatile surface engineering of the cellulosic nanomaterials via organocatalysis and click chemistry. Here, organoclick chemistry enables the selective functionalization of nanocelluloses with different organic molecules as well as the binding of palladium ions or nanoparticles. The nanocellulosic material is also shown to function as a sustainable support for heterogeneous catalysis in modern organic synthesis (e.g., Suzuki cross-coupling transformations in water). The reported strategy not only addresses obstacles and challenges for the future utilization of nanocellulose (e.g., low moisture resistance, the need for green chemistry, and energy-intensive production) but also enables new applications for nanocellulosic materials in different areas.

Redesign and Evaluation of a Technology Enhanced Learning Environment for Thesis Supervision
- 2017

- Thesis supervision is an important activity in higher education with Bachelor’s and Master’s theses mandatory parts of university programmes. In traditional education, thesis supervision has been a face-to-face activity, but today, both the student groups and the learning environments are blended. This study describes and discusses the design and implementation of a blended learning environment for a student group at Mid Sweden University. The research question that the study aims to answer is: Which are the important factors in the design of a course for undergraduate students, to facilitate supervision of thesis projects in a technology enhanced environment? This study employed a Design science research strategy with three phases for design, implementation and evaluation of a blended learning environment during thesis supervision. For the first phase, design requirements were specified based on document studies and a literature review. In the second phase (first part), the created design requirements were implemented as an instance in the Moodle virtual learning environment. Second phase (second part), the implemented instance was used as the online part of a blended learning course for students writing their Bachelor’s thesis. In the third phase an evaluation was carried out with an online questionnaire were students gave their opinions on course design and teaching and learning sessions. Findings show that the learning outcomes were good and that the course aim and the learning objectives were clearly stated. Found important factors for a successful supervision were peer collaboration, multimodality, and technology enhanced interaction. Remaining challenges are to improve course content and to motivate students for research in the field of Informatics. Most surprising positive finding was that peer situation occurred informally, which deepen their knowledge for thesis writing and presentation.

Konferensbidrag (refereegranskat)abstract
- In the biomedical sector, pressure sensors exhibit an important role towards monitoring and recognition of sitting posture for wheelchair users, which is helpful for pressure ulcer prevention and cure. In this paper, a flexible and inexpensive screen printed large area pressure sensing system is presented. The large area sensor comprise three layers, is able to cancel-out false pressure detection, and achieves a sitting classification accuracy over 80 percent. The sensor matrix contains 16 sensors distributed over an area of 23.5 cm × 21.5 cm and the pressure points are monitored at a scanning rate of 77 Hz. The sensor system provides wireless communication and a Windows based GUI is developed that allows real-time presentation of pressure data by means of a pressure map. The presented sensor design targets smart wheelchairs but is suitable for any low cost and high throughput pressure distribution monitoring systems.

Interpreting Plenoptic Images as Multi-View Sequences for Improved Compression
- 2017
-
Ingår i: ICIP 2017. - : IEEE. - 9781509021758 ; , s. 4557-4561
-
Konferensbidrag (refereegranskat)abstract
- Over the last decade, advancements in optical devices have made it possible for new novel image acquisition technologies to appear. Angular information for each spatial point is acquired in addition to the spatial information of the scene that enables 3D scene reconstruction and various post-processing effects. Current generation of plenoptic cameras spatially multiplex the angular information, which implies an increase in image resolution to retain the level of spatial information gathered by conventional cameras. In this work, the resulting plenoptic image is interpreted as a multi-view sequence that is efficiently compressed using the multi-view extension of high efficiency video coding (MV-HEVC). A novel two dimensional weighted prediction and rate allocation scheme is proposed to adopt the HEVC compression structure to the plenoptic image properties. The proposed coding approach is a response to ICIP 2017 Grand Challenge: Light field Image Coding. The proposed scheme outperforms all ICME contestants, and improves on the JPEG-anchor of ICME with an average PSNR gain of 7.5 dB and the HEVC-anchor of ICIP 2017 Grand Challenge with an average PSNR gain of 2.4 dB.
