The unexpected admission of a child to the pediatric intensive care unit (PICU) creates feelings of uncertainty, distress, and fear and is a devastating experience for primary caregivers. Health care providers must address primary caregivers` concerns to enhance primary caregivers’ coping abilities. While a family-centred approach to care can assist in diminishing uneasy feelings experienced by primary caregivers, this philosophy of care is not consistently used in everyday practice. The PICU is a unique area of care that focuses on restoring the health of critically ill children with the use of machines and equipment. However, the use of technology for life sustaining measures creates additional responsibilities for health care providers, potentially compromising the quality of patient care. There is evidence to support that the involvement of the primary caregiver in the care of the critically child can address the gap that commonly exists between technology and holistic patient care. Furthermore, involvement in care increases primary caregivers’ satisfaction with the care their child receives and may also improve patient outcomes. Most importantly, the involvement of primary caregivers in the care of the critically ill child encompasses a family-centred approach to care. By increasing health care provider’s awareness of family-centred care within the PICU, primary caregiver’s needs may be more effectively addressed during this devastating and vulnerable time. Health care providers are key players in the promotion of family-centred care in the PICU; however, they are often faced with multiple challenges and barriers. Increasing health care providers’ awareness around the components of family-centred care can facilitate its implementation into practice by understanding how primary care givers define and experience ii family-centred care. Accordingly, a qualitative study guided by the philosophy of hermeneutic phenomenology was conducted to elicit a detailed description of the lived experience of family-centred care from the perspective of the primary caregiver. Participants in this study consisted of those primary caregivers who had previously had a child admitted to the PICU. Participants were recruited from a large mid-western hospital. In total nine primary caregivers ranging in age from 33 to 44 years with the mean age being 37 years participated in the study. Nine of the participants were mothers and two were fathers. All participants took part in semi-structured, open-ended interviews. A total of nine interviews were conducted with two of the interviews involving both parents. Demographic data and field notes were recorded. All field notes and interview data were transcribed. The transcripts were reviewed repeatedly for significant statements in an attempt to find meaning and understanding through themes. The data analysis revealed the essence of the lived experience of family-centred care to be being present. Three themes communicated the essence and included: (a) physical presence, (b) participation in care and, (c) advocating. Three themes from the data emerged around how primary caregivers defined family-centred care and included: (a) collaboration, (b) being updated and, (c) continuity of care. Finally, primary caregivers identified four conditions that needed to be in place to experience family-centred in the PICU which included: (a) being present for rounds, (b) caring behaviours, (c) feeling welcomed and, (d) support. The findings from this study may be used to guide policy around family-centred care and improve on, or bring new insights around interventions related to family-centred care. Future recommendation for nursing practice, education and research are presented.

Processors used in lower-end scientific applications like graphic cards and video game consoles have IEEE single precision floating-point hardware [23]. Double precision offers higher precision at higher implementation cost and lower performance. The need for high precision computations in these applications is not enough to justify the use double precision hardware and the extra hardware complexity needed [23]. Native-pair arithmetic offers an interesting and feasible solution to this problem. This technique invented by T. J. Dekker uses single-length floating-point numbers to represent higher precision floating-point numbers [3]. Native-pair arithmetic has been proposed by Dr. William R. Dieter and Dr. Henry G. Dietz to achieve better accuracy using standard IEEE single precision floating point hardware [1]. Native-pair arithmetic results in better accuracy however it decreases the performance by 11x and 17x for addition and multiplication respectively [2]. The proposed implementation uses a residual register to store the error residual term [2]. This addition is not only cost efficient but also results in acceptable accuracy with 10 times the performance of 64-bit hardware. This thesis demonstrates the implementation of a 32-bit floating-point unit with residual register and estimates the hardware cost and performance.

The aim of the study was to gain a deeper understanding of the expectations that assistant nurses in the elderly care have on unit manager's leadership and the consequences if the expectations are not met. To answer the purpose of this paper a qualitative research was conducted with interviews with six assistant nurses in municipal elderly care. To analyze the empirical material communication were used as a theoretical concept. Communication includes codes, signals and messages to be interpreted by the parties in a conversation and they can be both verbal and nonverbal. This means that communication is complicated and can cause confusion if it is interpreted wrong. Both literature and the results of the interviews showed that the director has a lot of expectations on him- or herself. What among other things emerged was that the manager should be involved in employees' work, he should be knowledgeable about the organization and be able to give confidence to the families and this by including external characteristics argued the interviewees. Another important part of the result was that the manager should support staff, providing them with appreciation as this makes them feel good and do more at work. The consequence of the result showed a reduced commitment when expectations are not met. The decreased involvement came partly from the unit manager being in a terminal position, among other things, employees do not bring their ideas to the manager's because he do not introduce them without first asking his director for "permission". The second consequence was crap talk. Crap talk turned out to poison the workplace if among other things, conflicts were not handled or if the employees received too little information. / Syftet med studien var att få en fördjupad förståelse för de förväntningar som undersköterskorna i äldreomsorgen har på enhetschefernas ledarskap samt vilka konsekvenserna blir om förväntningarna inte uppfylls. För att besvara syftet genomfördes en kvalitativ studie. Det empiriska materialet består av intervjuer gjorda med sex undersköterskor inom den kommunala äldreomsorgen. För att analysera det empiriska materialet användes kommunikation som teoretiskt begrepp. Kommunikation innefattar koder, signaler och budskap som ska tolkas av parterna i ett samtal och dessa visar sig både verbalt och ickeverbalt. Detta gör att kommunikation är komplicerat och kan leda till missförstånd om det tolkas fel. Både litteraturen och resultaten från intervjuerna visade att chefen har en hel del förväntningar på sig. Det som bland annat framkom var att chefen ska vara engagerad i medarbetarnas arbete, denne ska vara kunnig om organisationen och kunna inge förtroende både till medarbetarna och till de anhöriga. En annan viktig del i resultatet var att chefen ska stödja personalen, ge dem uppskattning då detta gör att de mår bra och gör mer på arbetet. De konsekvenser som följer om förväntningarna inte uppfylls var ett minskat engagemang. Det minskade engagemanget kom bland annat från att chefen befinner sig i en klämposition som till viss del innebär att medarbetarna inte kommer med sina idéer till chefen då denne inte inför dem utan att först fråga verksamhetschefen om ”lov”. Den andra konsekvensen var skitsnack. Skitsnacket visade sig kunna förpesta en hel arbetsplats om bland annat konflikter inte hanterades eller om medarbetarna fått för lite information.

Bakgrund: Sömn är ett mänskligt grundläggande behov och bör därför tillgodoses hos patienter som vårdas på sjukhus. Patienter som vårdas på intensivvårdsavdelningar upplever dock ofta upprepade avbrott på sömnen och sömnbrist vilket kan leda till både fysiska och psykiska negativa konsekvenser. Intensivvårdsmiljön med dess oljud, starka belysning och frekventa vårdrelaterade interaktioner leder ofta till oförmåga hos patienterna att få en adekvat sömn. Syfte: Att belysa olika interventioner sjuksköterskan kan tillämpa för att förbättra sovmiljön och sömnkvaliteten hos patienter som vårdas på en intensivvårdsavdelning. Metod: En litteraturöversikt med grund i analys av kvantitativ forskning. Resultat: I resultatet framkom sju interventioner som delades in i tre olika kategorier: skapa en bättre sovmiljö, avskärmning från ljud och ljus samt förbereda patienten för sömn. De sju interventionerna som identifierades var: tysta/störningsfria perioder, riktlinjer/ramverk innefattande aktiviteter för att kontrollera yttre störande faktorer, utbildning, öronproppar och ögonmask, adderat "white noise", musik samt akupressur. Slutsats: Genom att tillämpa en eller fler av de sju interventionerna kan sovmiljön och sömnkvalitet förbättras för patienter som vårdas på intensivvårdsavdelningar. Dock krävs ytterligare forskning inom området då vissa interventioner ger motstridiga resultat. Klinisk betydelse: Sömn är ett nödvändigt behov och har en stor betydelse för återhämtning från sjukdom och bör därför tillgodoses av sjuksköterskan. Resultatet i denna litteraturöversikt kan ge en ökad förståelse för vilka interventioner sjuksköterskan kan tillämpa i sitt omvårdnadsarbete för att förbättra sovmiljön och sömnkvalitet för patienter som vårdas på intensivvårdsavdelningar. / Background: Sleep is a basic human need and should be addressed in patients being treated in hospital. Patients cared for in intensive care units often experience repeated interruptions of sleep and sleep deprivation, which can lead to both physical and psychological adverse consequences. The intensive care environment with its noise, strong lighting and frequent care-related interaction often leads to the inability of patients to get adequate sleep. Aim: To illustrate the various interventions the nurse can implement to improve the sleep environment and quality of sleep in patients who are cared for in an intensive care unit. Methods: A literature review with its basis in an analysis of quantitative research. Results: The result emerged in seven interventions that were divided into three different categories: creating a better sleep environment, shielding from light and sound, and preparing the patient for sleep. The seven interventions identified were: quiet/non-disturbance periods, guidelines/framework including activities to control disturbing environmental factors, education, ear plugs and eye mask, added "white noise", music and acupressure. Conclusion: By applying one or more of the seven interventions the sleep environment and sleep quality for patients cared for in intensive care units may improve. However, as some interventions produced conflicting results, further research in the area is required. Clinical significance: Sleep is an essential requirement and has great importance in the recovery from illness and should therefore be carefully understood by the nurse. Findings from the literature review can provide a better understanding of which interventions nurses can apply in their work to improve the sleep environment and sleep quality for patients cared for in intensive care units.

Background: Events happening in the 21st century- global economic crisis, naturaldisasters, extreme poverty, struggles and conflicts have led to a realization that we areliving in a troubled world where we are interdependent in one way or the other. These issues tend to be complex and intertwined such that delegating them to a single sectoris too huge of a task to bear, thus the need for social innovation through cross sector collaboration. The case of the Refugee Housing Unit is being studied- a collaboration between the IKEA Foundation, UNHCR and the Swedish Industrial Design Foundation led to the creation of a more sustainable environmental friendly shelter for refugees.Since social innovation is a green field especially in a BOP context, the research is aimed at understanding how the RHU case can provide important insight in which collaboration theory can be applied between sectors to shape future social innovation endeavors. Aim: The aim of this thesis is to study the collaboration of organizations belonging to different sectors to create social innovations. This research will examine how collaboration between sectors takes place, and through the empirical case of theRefugee Housing Unit, derive key learning points that could shape future social innovation projects. A framework will be developed that could provide important insightsfor future socially oriented collaborations. Methodology: The proposed framework was developed through a study of socialinnovation theory in terms how it can be accelerated through cross sector collaborationiitheory. A case study that entailed these two theories was chosen to enable the development of a suggested framework. The study involved collection of primary data inform of interviews with Johan Karlsson and Chris Earney, RHU project leader and UNHCR Innovation co-leader, respectively. Additionally, secondary data was used tohelp understand the case further. Results: Examining the core elements of cross-sectoral collaboration for social innovation showed imperative social aspects as well as key dimensions that are pillars for the process of collaboration. The RHU case revealed critical factors for collaboration between sectors that are well stipulated in the framework. The framework can act as a guide for organizations wishing to collaborate for social innovation as well as provide abasis for future research in this young field.

The pediatric intensive care unit (PICU) has been described as a stressful place for parents of critically ill children. Research to date has examined parents’ needs and stressors with a child in PICU. There is a paucity of research examining the experience for parents of a child who is transferred from the PICU to the hospital ward. Open-ended interviews were conducted with 10 parents within 24-48 hours after transfer from a PICU to a hospital ward at a children’s hospital in Canada to understand this experience. Parents revealed that the experience involved a search for comfort through transitions as expressed through the themes of: ‘being a parent with a critically ill child is exhausting’, ‘being kept in the know’, ‘feeling supported by others’, and ‘being transferred’. The findings from this study can help nurses and other health professionals working with parents to support them through the transition from PICU. Recommendations are made for the inclusion of family-centered care practices to assist parents through transitions.

This master’s thesis, carried out at MAN Truck & Bus AG, presents a self-observational case study of the software  development  methodology  Test-driven  development  (TDD)  in  the  context  of  developing  a framework  for  human-machine  interface  concepts  in  commercial  vehicles.  Software  developers  are constantly looking for ways to improve productivity and the quality of their code. TDD has been said to do precisely this, but not many experience reports from new practitioners can be found, making it difficult to know what to expect when using it for the first time. This thesis focuses on the experiences of a beginner to the TDD practice and follows the development of the framework and the changes made to the design over time. The framework, consisting of a C++ server application and an Android client, was developed using TDD. Decisions, obstacles and general experiences from the development process are documented in this report with the aim of finding out how TDD works in practice for a beginner and how well the practice is suited for this particular kind of project. It was concluded that TDD seems to have both benefits and drawbacks, as it appears to facilitate lower coupling of the code and a more structured design, but also complicates the changing of public interfaces since the changes often also affect the test code. Subjectively perceived effects of the practice included that developer  focus  improved,  that  testing  actually  occurred  and  that  the  continuous  passing  of  tests  gave confidence and a sense of accomplishment to the developer. Furthermore it was concluded that experienced developers may reap more benefits from TDD whereas developers with little experience might have a harder time  adjusting  to  the  practice  and  may  not  see  any  notable  improvement  on  the  design.  The  observed developer in this study also found that TDD was difficult to get used to and that it would have been helpful to initially pair up with an experienced TDD practitioner to be properly guided through the first steps and to form good habits. Some  parts  of  the  framework  developed  were  left  out  of  the  TDD  because  of  complexity  and  time reasons, leading the suitability of the practice for similar frameworks to be judged as moderate. The areas that  induced  problematic  situations  were  multithreading,  networking  and  graphical  user  interfaces  which were all considered difficult to handle with TDD.

Optimal generation scheduling attempts to minimise the cost of power production while satisfying the various operation constraints and physical limitations on the power system components. The thermal generation scheduling problem can be considered as a power system control problem acting over different time frames. The unit commitment phase determines the optimum pattern for starting up and shutting down the generating units over the designated scheduling period, while the economic dispatch phase is concerned with allocation of the load demand among the on-line generators. In a hydrothermal system the optimal scheduling of generation involves the allocation of generation among the hydro electric and thermal plants so as to minimise total operation costs of thermal plants while satisfying the various constraints on the hydraulic and power system network. This thesis reports on the development of genetic algorithm computation techniques for the solution of the short term generation scheduling problem for power systems having both thermal and hydro units. A comprehensive genetic algorithm modelling framework for thermal and hydrothermal scheduling problems using two genetic algorithm models, a canonical genetic algorithm and a deterministic crowding genetic algorithm, is presented. The thermal scheduling modelling framework incorporates unit minimum up and down times, demand and reserve constraints, cooling time dependent start up costs, unit ramp rates, and multiple unit operating states, while constraints such as multiple cascade hydraulic networks, river transport delays and variable head hydro plants, are accounted for in the hydraulic system modelling. These basic genetic algorithm models have been enhanced, using quasi problem decomposition, and hybridisation techniques, resulting in efficient generation scheduling algorithms. The results of the performance of the algorithms on small, medium and large scale power system problems is presented and compared with other conventional scheduling techniques.
