The need for faster, more flexible and less risky ways for organisations to expand their capabilities and competencies increasingly lead to the formation and proliferation of networking strategies and partners. Understanding the potential contribution that CoP membership can provide within these teams is a step towards developing and refining a strategy to support and enhance the speedy progression of the team towards a productive phase. The study shows that membership of researchers to the same or similar CoPs have some impact on the norming stage, and assist in reaching the performing / productive stage faster in team development. The survey in particular has indicated that similar standards, practices, terminology, ethics, standards, peer recognition, trust and a sense of belonging have more of an impact on the productive phase of team forming, than on the norming phase. The hard factors such as terminology, standards and similar practices have a strong correlation with the softer factors such as a sense of belonging and trust. This information should be utilised in both the socialisation processes in academic institutions as part of the education of professionals, as well as organisational approaches to Research and Development (R&D), information sharing and development of the researchers. The paper also highlights emerging organisational and strategic Best Practices currently prevalent in R&D teams and collaborative projects. It is clear that research collaborations cuts across the whole spectrum of business and management areas - from strategy, across intellectual property issues, finance, strategic human resource management, R&D management and innovation, knowledge management, organisational values and culture, and many more. To support innovation and R&D on a strategic level, both internally and on inter-firm collaborations, requires a review of the total organisational strategy, culture and norms in an organisation. Innovation and R&D support should be a holistic approach, with strategic and pro-active risk management supported by appropriate strategic human resources management and systems. Literature on CoPs, teams, social capital (SC), knowledge management (KM), intellectual capital (IC), intellectual property (IP), strategy and governance provide theoretical grounding. / Business Leadership / Ph.

Main goal of this work is familiarization with basic features of absorption heat pumps and it’s growing importance on the market. In the first part of the work there is a research for clarifying facts associated with such pumps. In the introduction there are descriptions of basic information from the field of heating industry and its connections to our systems. Next there is a brief analysis of price changes in electricity and heat in the last five years. Main part of the analytical section is a description of the used absorption system. Second part of the work is focused on the calculation of the absorption system itself. First there is calculated internal and external part of the device according to the parameters from GE Power s.r.o. After this step there are parametric studies based on changes of key parameters of the default device for a demonstration of the behavior of a heating pump. In the end of the work there is a integration of the unit into the heating cycle for variations including flue gas condenser and using a cooling water from the turbine condenser.

Background: Gait initiation is a major issue in Parkinson’s disease (PD). Moreover, the effect of current treatment on motor deficits vary alongside individual differences and disease severity. In some cases, postural instability has been documented as a major side-effect and refractory symptom to dopaminergic medication. Despite these shortcomings, research involving other forms of therapy including deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS), has evidenced the improvement of postural deficits in PD. In this regard, there is a strong rational for the modulation of subcortical brain activity via the application of non-invasive transcranial direct current stimulation (tDCS) to interconnected cortical brain structures. Purpose: Therefore, we sought to determine the effect of tDCS applied to the supplementary motor area (SMA), on gait initiation preparation and performance in PD. Methods: A within subjects repeated measures quasi-experimental design was used to investigate the effects of a 10-minute sham-controlled tDCS intervention. Clinically diagnosed participants (n=12) with idiopathic PD were tested on medication during two sessions that bookended one week. Those who had previously undergone other forms of brain stimulation, had diabetes, severe freezing of gait, or any other neurological or functional limitations that could interfere with gait initiation were excluded from the study. Statistical Analyses/Results: Two-way repeated measures ANOVAs with Bonferroni corrections and a post-hoc analyses when appropriate, revealed a significant reduction in the magnitude of center of pressure (CoP) displacement and velocity in the mediolateral (ML) direction following tDCS. Conclusions: Findings from this study provide insights that may guide scientific research regarding the effects of tDCS on gait initiation among those with PD. Additionally, our work may highlight the importance of ML postural stability for individuals with comorbid and/or pharmacologically induced postural instabilities.

The project elaborates design opportunities for a future practice that could promotealternative sustainable lifestyles on waste handling through up-cycling activities. It doesthis on a small scale through engagement in the local communities of the Hildaneighborhood and Segepark students’ accommodations in Sweden. To thesecommunities, creative-up-cycling is explored which it introduced here as an approachwhere neighbors can participate in making new things from leftover materials. Throughthis work creative-up-cycling is a proposed recommendation for a possible service systemon how to share the leftover materials in the local resident’s communities, as well as, howto remake the items no longer needed.The empirical studies explore maker culture lifestyles and include how to find leftovermaterials, tools, space, and skills in order to guide people in creative-up-cyclingalternatives. These creative activities also build social relationship via the integration ofmultidisciplinary citizens who are living in the same community and explorations weredone on how could we elicit the skill sets from those people? What is a useful skill set inthis area today? Values like mutual physical experience, reciprocity, and ownership couldalso be found along the empirical workshops in this project. Additionally, this reportshows some interesting findings pointing towards the design process and the suggestionsof design elements; ‘Co-storage’, ‘Mix and Match furniture shop’, and ‘Renovation andup-cycling’ concept elements.Participatory design (designing with people) has been the core approach in this project.Additionally, I have been influenced by user-centered design, as well as service designapproaches in order to comprehend the services, system and activities of recycling andup-cycling in cities like: SYSAV, STPLN, Cykelköket, Återskapa, Toolpool. The findingpresented here are examples of practices that could make up the composition of recyclingand up-cycling activities in future local communities.

Syftet med studien är att presentera ett designkoncept för publika diskussioner på nätet med målet att uppnå djupare diskussioner och minska mängden information overload. Arbetet använder metoden Concept Driven Interaction Design (CDID) som går ut på att skapa ett designkoncept utifrån flera olika teorier som appliceras genom interaktionsdesign. Ett designkoncept innehåller tre delar: ett namn, ett syfte och huvudprinciper. CDID innehåller sju steg som arbetet är utformat efter: 1.      Concept Generation – Summeras i en tabell som jämför diskussioner i forum (med flera antagande) och diskussioner med hjälp av metoden Philosophy for Children (P4C), samt annan teori. 2.      Concept Exploration – Åtta olika designaspekter identifieras utifrån jämförelsetabellen. 3.      Internal Concept Critique – Designaspekterna jämförs med två snarlika diskussionsformat. 4.      Design of Artifacts – Designkoncept version 1 skapas. 5.      External Design Critique – Intervjuer utförs för att undersöka intervjupersonerna generella erfarenheter av online diskussioner, testar antagandena från jämförelsetabellen och ge direkt feedback på första versionen av designkonceptet. 6.      Concept Revisited – Ändringar görs baserat på intervjumaterial och direkt feedback. 7.      Concept Contextualization – Designkonceptet kopplas tillbaka till litteraturen. Studien resulterar i ett designkoncept kallat CoFramer och stödjer dessa huvudprinciper som ställs i kontrast till material som identifierats genom intervjuerna: Tabell 1: CoFramers huvudprinciper och faktorer från intervjuer om diskussioner på forum. CoFramers huvudprinciper | Från intervjuer om diskussioner på forum Strukturerad början och slut | Diskussion utan tydligt slut Begränsat antal deltagare | Stor mängd deltagare Minimum antal deltagare | Många inaktiva åskådare Explicita deltagare | Lite information om deltagare Gemensamma förutsättningar | Otydlighet kring deltagares förutsättningar Begränsad informationstäthet per inlägg | Långa inlägg och/eller snabba inlägg Den röda tråden och parallella trådar | Oftast parallella trådar Aktiv samtalsledare | Outredda missförstånd Studien indikerar på att CoFramer bör resultera i mer strukturerade diskussioner och som utsätter användaren för en lägre mängd information overload och mindre grounding cost jämfört med vad som vanligtvis uppstår i publika diskussioner online. / The focus of this essay is to develop a design concept for online public discussions with deep discussions and low information overload. The method used is Concept Driven Interaction Design (CDID) which involves constructing a design concept by applying a variety of theories in tangible interaction design. A design concept has three basic parts: a name, high-level goals and outlines generic principles. CDID includes seven steps which is used in this work: 1.      Concept Generation – Formatted into a table that compare forum discussion (with several hypothesis) compared to discussions with the method Philosophy for Children (P4C) and other theories. 2.      Concept Exploration – Eight distinct design aspects are identified from the comparison table. 3.      Internal Concept Critique – The design aspects are compared to three similar discussion formats. 4.      Design of Artifacts – Design concept version 1 is created. 5.      External Design Critique – Interviews are conducted to explore their general experience of online discussions, investigate the hypothesis from the comparison table and to seek direct feedback on the first draft of the design concept. 6.      Concept Revisited – Changes are made to the design concept based on the interview material and the direct feedback. 7.      Concept Contextualization – The design concept is related to the original literature. The result of the study is a design concept named CoFramer. CoFramer’s generic principles are summarized and contrasted against factors identified from the interview material in this table: Tabell 2: CoFramer’s generic principles and interviews about online discussions. CoFramer’s generic principles | From interview material on forum discussion Organized start and ending | Discussions without clear ending Limited number of participants | Large number of participants Minimum number of participants | Large number of inactive spectators Explicit participants | Low information about participants Common conditions | Vagueness in participants conditions Limited information density per post | Long posts and/or fast posts The red thread and parallel threads | Often parallel threads Active facilitator | Unresolved misunderstandings The study indicates that CoFramer would create more structured discussions with a lower amount of information overload and less grounding cost compared what normally arise in public online discussions.

A spin-cast silicone membrane has been successfully bonded between two injection-molded microstructured plastic discs. This sandwich structure creates a useful platform for mass production of microfluidic systems, provided that the bonds are leakproof. The bonds were achieved by a silicon dioxide coating deposited on the plastic discs by evaporation. This investigation is concerned with the process and the result only, no theory is discussed.

The present thesis sought to compare participation in social types of play of children with and without hyperactivity in a Swedish preschool context. Based upon observational design of cross-sectional type, this study was built on a secondary analysis of data collected within two previous research projects that were merged into one dataset. A total of 583 children (n = 298 boys) aged 16 to 72 months (M = 52.55, SD = 11.01) were initially included in the sample. Preschool teachers rated children’s behavior difficulties on a hyperactivity scale using Strengths and Difficulties Questionnaire (SDQ). Structured observations of children’s attendance, engagement, verbal interaction, proximity and location during associative and cooperative interaction were conducted across day-long visits by three trained researchers using Children Observation in Pre- school (COP) tool. Conditional probability looping syntaxes were created and Independent sample t-Tests were used to analyze the data. Out of 572 children included in the analysis, n = 60 (10,2%) were rated as having some form of hyperactivity. On the whole, the findings illustrated that the observed averages of attendance and overall engagement in social types of play did not differ significantly between children with and without hyperactivity. However, an in-depth analysis of participation patterns, linked to contextual and environmental factors such as proximity and play location, revealed several considerable differences between the two groups of children. It seems that preschoolers with hyperactive behavior seek social play opportunities as much as their typical behavior peers, but the quality aspects of their experience defined by a specific context and environment may differ further as the interaction develops. Contextual and environmental factors are crucial determinants to take into account when studying participation. Play, operating as a natural booster of self-regulation and engagement may have the potential to serve as a mediating factor accommodating hyperactivity and promoting participation in Early Childhood Education settings.

This thesis presents work on a holistic approach for improving the overall design of solar cooling systems driven by solar thermal collectors. Newly developed methods for thermodynamic optimization of hydraulics and control were used to redesign an existing pilot plant. Measurements taken from the newly developed system show an 81% increase of the Solar Cooling Efficiency (SCEth) factor compared to the original pilot system. In addition to the improvements in system design, new efficiency factors for benchmarking solar cooling systems are presented. The Solar Supply Efficiency (SSEth) factor provides a means of quantifying the quality of solar thermal charging systems relative to the usable heat to drive the sorption process. The product of the SSEth with the already established COPth of the chiller, leads to the SCEth factor which, for the first time, provides a clear and concise benchmarking method for the overall design of solar cooling systems. Furthermore, the definition of a coefficient of performance, including irreversibilities from energy conversion (COPcon), enables a direct comparison of compression and sorption chiller technology. This new performance metric is applicable to all low-temperature heat-supply machines for direct comparison of different types or technologies. The achieved findings of this work led to an optimized generic design for solar cooling systems, which was successfully transferred to the market.
