Abstract:
Using data from the Integrated Global Radiosonde Archive Version 2 (IGRA2) and the Multi Model Ensemble (MME) of four global climate models (GCMs), named CanESM5, IPSL-CM6A-LR, MIROC6, and MRI-ESM2-0, within the framework of phase 6 of the Coupled Model Intercomparison Project (CMIP6), we analyzed the changes in atmospheric total column water vapor (TCWV) over Central Asia in the future (2021–2100) under SSP-RCPs scenarios: SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP4-3.4, SSP4-6.0, and SSP5-8.5, relative to baseline period (1986–2005). Results showed that the annual mean TCWV from IGRA2 was consistent with the model output from 1979 to 2014 in Central Asia. Besides, the spatial distribution of TCWV in Central Asia during the baseline period was consistent between the models. The regional average value of Central Asia was between 10.8 mm and 12.4 mm, and decreased with elevation. TCWV will increase under different SSP-RCPs from 2021 to 2040, but showed different trends after 2040. It will increase under SSP1-1.9 and SSP1-2.6 scenarios from 2021 to 2050, and decrease after that. It will grow from 2021 to 2055 under SSP4-3.4 scenario, and then stay essentially constant. Under SSP2-4.5 and SSP4-6.0 scenarios, TCWV will rise rapidly during 2021–2065, but the growth will decline from 2065 to 2100. TCWV will continue to increase under SSP3-7.0 and SSP5-8.5 scenarios, and the largest increase is projected under SSP5-8.5 scenario. Change in near-surface temperature (Ts) matched the change in TCWV, but changes in precipitation and evapotranspiration are not significant during 2021–2100. In spite of the large variations in TCWV under different SSP-RCPs, the dominant characteristic in all scenarios shows that a large TCWV increase is demonstrated over areas with small TCWV amounts during the baseline period. On the contrary, increases will be small where the TCWV amounts had been large during the baseline period. The change in TCWV is highly correlated to the increase in Ts in Central Asia. Under SSP2-4.5, SSP3-7.0, SSP4-3.4, SSP4-6.0, and SSP5-8.5 scenarios, the higher the temperature due to higher radiative forcing, the steeper the regression slope between TCWV and Ts change. It is closest to the theoretical value of the Clausius-Clapeyron equation under SSP3-7.0 and SSP5-8.5 scenarios, but not presented under other scenarios. Spatially, steeper regression slopes during 2021–2100 have been found around the Caspian Sea in the southwest and in the high-elevation areas in the southeast of Central Asia, which is likely related to the abundant local water supply for evaporation.

Abstract:
This study compares and analyzes simulations of ozone under different scenarios by three CMIP6 models (IPSL-CM6A, MRI-ESM2 and CESM-WACCM). Results indicate that as the social vulnerability and anthropogenic radiative forcing is increasing, the change of total column ozone in the tropical stratosphere is not linear. Compared to the SSP2-4.5 and SSP5-8.5 scenarios, the SSP1-2.6 and SSP3-7.0 are more favorable for the increase in stratospheric ozone mass in the tropics. Arctic ozone would never recover under the SSP1-2.6 scenario; however, the Antarctica ozone would gradually recover in all scenarios. Under the SSP1-2.6 and SSP2-4.5 scenarios, the trend of tropical total column ozone is mainly determined by the trend of column ozone in the tropical troposphere. Under the SSP3-7.0 scenario, tropospheric ozone concentration will significantly increase; under the SSP5-8.5 scenario, ozone concentration will distinctly increase in the middle and lower troposphere.

Abstract:
Technological changes in water use efficiency directly influence regional sustainable development. However, few studies have attempted to predict changes in water use efficiency because of the complex influencing factors and regional diversity. The Chinese Government has established a target of 0.6 for the effective utilization coefficient of irrigation water, but it is not clear how the coefficient will change in different provinces in the future. The purpose of this study is to predict irrigation water use efficiency changes using a conditional convergence model and combined with the shared socioeconomic pathways (SSPs) scenario settings and hydro-economic (HE) classification to group 31 Chinese provinces by their different economic and water resources conditions. The results show that the coefficient exponentially converges to 0.6 in half the provinces under SSP1 (sustainability), SSP2 (middle of the road), and SSP5 (conventional development) by 2030, whereas SSP3 (fragmentation) and SSP4 (inequality) are generally inefficient development pathways. HE-3 provinces (strong economic capacity, substantial hydrological challenges) achieve the greatest efficiency improvements (with all coefficients above 0.6), and SSP1 is a suitable pathway for these provinces. HE-2 provinces (strong economic capacities, low hydrological challenges) have relatively low efficiency because they lack incentives to save water, and SSP1 is also suitable for these provinces. For most HE-1 provinces (low economic capacity, low hydrological challenges), the coefficients are less than 0.6, and efforts are required to enhance their economic capacity under SSP1 or SSP5. HE-4 provinces (low economic capacity, substantial hydrological challenges) would improve efficiency in a cost-efficient manner under SSP2.

Abstract:
Abstract. Stratospheric ozone and water vapour are key components of the Earth system, and past and future changes to both have important impacts on global and regional climate. Here, we evaluate long-term changes in these species from the pre-industrial period (1850) to the end of the 21st century in Coupled Model Intercomparison Project phase 6 (CMIP6) models under a range of future emissions scenarios. There is good agreement between the CMIP multi-model mean and observations for total column ozone (TCO), although there is substantial variation between the individual CMIP6 models. For the CMIP6 multi-model mean, global mean TCO has increased from ∼ 300 DU in 1850 to ∼ 305 DU in 1960, before rapidly declining in the 1970s and 1980s following the use and emission of halogenated ozone-depleting substances (ODSs). TCO is projected to return to 1960s values by the middle of the 21st century under the SSP2-4.5, SSP3-7.0, SSP4-3.4, SSP4-6.0, and SSP5-8.5 scenarios, and under the SSP3-7.0 and SSP5-8.5 scenarios TCO values are projected to be ∼ 10 DU higher than the 1960s values by 2100. However, under the SSP1-1.9 and SSP1-1.6 scenarios, TCO is not projected to return to the 1960s values despite reductions in halogenated ODSs due to decreases in tropospheric ozone mixing ratios. This global pattern is similar to regional patterns, except in the tropics where TCO under most scenarios is not projected to return to 1960s values, either through reductions in tropospheric ozone under SSP1-1.9 and SSP1-2.6, or through reductions in lower stratospheric ozone resulting from an acceleration of the Brewer–Dobson circulation under other Shared Socioeconomic Pathways (SSPs). In contrast to TCO, there is poorer agreement between the CMIP6 multi-model mean and observed lower stratospheric water vapour mixing ratios, with the CMIP6 multi-model mean underestimating observed water vapour mixing ratios by ∼ 0.5 ppmv at 70 hPa. CMIP6 multi-model mean stratospheric water vapour mixing ratios in the tropical lower stratosphere have increased by ∼ 0.5 ppmv from the pre-industrial to the present-day period and are projected to increase further by the end of the 21st century. The largest increases (∼ 2 ppmv) are simulated under the future scenarios with the highest assumed forcing pathway (e.g. SSP5-8.5). Tropical lower stratospheric water vapour, and to a lesser extent TCO, shows large variations following explosive volcanic eruptions.

Abstract:
The main goal of this study was to assess the interannual variations and spatial patterns of projected changes in simulated evapotranspiration (ET) in the 21st century over continental Africa based on the latest Shared Socioeconomic Pathways and the Representative Concentration Pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5) provided by the France Centre National de Recherches Météorologiques (CNRM-CM) model in the Sixth Phase of Coupled Model Intercomparison Project (CMIP6) framework. The projected spatial and temporal changes were computed for three time slices: 2020–2039 (near future), 2040–2069 (mid-century), and 2080–2099 (end-of-the-century), relative to the baseline period (1995–2014). The results show that the spatial pattern of the projected ET was not uniform and varied across the climate region and under the SSP-RCPs scenarios. Although the trends varied, they were statistically significant for all SSP-RCPs. The SSP5-8.5 and SSP3-7.0 projected higher ET seasonality than SSP1-2.6 and SSP2-4.5. In general, we suggest the need for modelers and forecasters to pay more attention to changes in the simulated ET and their impact on extreme events. The findings provide useful information for water resources managers to develop specific measures to mitigate extreme events in the regions most affected by possible changes in the region’s climate. However, readers are advised to treat the results with caution as they are based on a single GCM model. Further research on multi-model ensembles (as more models’ outputs become available) and possible key drivers may provide additional information on CMIP6 ET projections in the region.

Abstract:
Abstract The aim of this study was to compare the dosimetric parameters of whole-pelvic radiotherapy (WPRT) for cervical cancer among plans involving 3D conformal radiotherapy (3D-CRT), intensity-modulated radiotherapy (IMRT), or spot-scanning proton therapy (SSPT). The dose distributions of 3D-CRT-, IMRT-, and SSPT-based WPRT plans were compared in 10 patients with cervical cancer. All of the patients were treated with a prescribed dose of 50.4 Gy in 1.8-Gy daily fractions, and all of the plans involved the same planning target volume (PTV) constrictions. A 3D-CRT plan involving a four-field box, an IMRT plan involving seven coplanar fields, and an SSPT plan involving four fields were created. The median PTV D95% did not differ between the 3D-CRT, IMRT and SSPT plans. The median conformity index 95% and homogeneity index of the IMRT and SSPT were better than those of the 3D-CRT. The homogeneity index of the SSPT was better than that of the IMRT. SSPT resulted in lower median V20 values for the bladder wall, small intestine, colon, bilateral femoral heads, skin, and pelvic bone than IMRT. Comparing the Dmean values, SSPT spared the small intestine, colon, bilateral femoral heads, skin and pelvic bone to a greater extent than the other modalities. SSPT can reduce the irradiated volume of the organs at risk compared with 3D-CRT and IMRT, while maintaining excellent PTV coverage. Further investigations of SSPT are warranted to assess its role in the treatment of cervical cancer.

Abstract:
ABSTRACT Eleven small, acid-soluble proteins (SASP) which are present in spores but not in growing cells of Bacillus subtilis were identified by sequence analysis of proteins separated by acrylamide gel electrophoresis of acid extracts from spores which lack the three major SASP (α, β, and γ). Six of these proteins are encoded by open reading frames identified previously or by analysis of the complete sequence of the B. subtilis genome, including two minor α/β-type SASP (SspC and SspD) and a putative spore coat protein (CotK). Five proteins are encoded by short open reading frames that were not identified as coding regions in the analysis of the completeB. subtilis genomic sequence. Studies of the regulation of two of the latter genes, termed sspG and sspJ, showed that both are expressed only in sporulation. ThesspG gene is transcribed in the mother cell compartment by RNA polymerase with the mother cell-specific sigma factor for RNA polymerase, ςK, and is cotranscribed with a downstream gene, yurS; sspG transcription also requires the DNA binding protein GerE. In contrast, sspJ is transcribed in the forespore compartment by RNA polymerase with the forespore-specific ςG and appears to give a monocistronic transcript. A mutation eliminating SspG had no effect on sporulation or spore properties, while loss of SspJ caused a slight decrease in the rate of spore outgrowth in an otherwise wild-type background.

Abstract:
We used CMIP6 GCMs to quantify climate change impacts on precipitation and potential evapotranspiration (PET) across water management zones (WMZs) in Uganda. Future changes are assessed based on four Shared Socioeconomic Pathways (SSP) scenarios including SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 over the periods 2021–2040, 2041–2060, 2061–2080, and 2081–2100. Both precipitation and PET are generally projected to increase across all the WMZs. Annual PET in the 2030s, 2050s, 2070s, 2090s will increase in the ranges 1.1–4.0%, 4.8–7.9%, 5.1–11.8%, and 5.3–17.1%, respectively. For the respective periods, annual precipitation will increase in the ranges 4.0–7.8%, 7.8–12.5%, 7.9–19.9%, and 6.9–26.3%. The lower and upper limits of these change ranges for both precipitation and PET are, respectively, derived under SSP1-2.6 and SSP5-8.5 scenarios. Climate change will impact on PET or precipitation disproportionately across the WMZs. While the eastern WMZ (Kyoga) will experience the largest projected precipitation increase especially towards the end of the century, the southern WMZ (Victoria) exhibited the largest PET increase. Our findings are relevant for understanding hydrological impacts of climate change across Uganda, in the background of global warming. Thus, the water sector should devise and implement adaptation measures to impede future socioeconomic and environmental crises in the country.

Abstract. The Scenario Model Intercomparison Project (ScenarioMIP) defines and coordinates the main set of future climate projections, based on concentration-driven simulations, within the Coupled Model Intercomparison Project phase 6 (CMIP6). This paper presents a range of its outcomes by synthesizing results from the participating global coupled Earth system models. We limit our scope to the analysis of strictly geophysical outcomes: mainly global averages and spatial patterns of change for surface air temperature and precipitation. We also compare CMIP6 projections to CMIP5 results, especially for those scenarios that were designed to provide continuity across the CMIP phases, at the same time highlighting important differences in forcing composition, as well as in results. The range of future temperature and precipitation changes by the end of the century (2081–2100) encompassing the Tier 1 experiments based on the Shared Socioeconomic Pathway (SSP) scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5) and SSP1-1.9 spans a larger range of outcomes compared to CMIP5, due to higher warming (by close to 1.5 ∘C) reached at the upper end of the 5 %–95 % envelope of the highest scenario (SSP5-8.5). This is due to both the wider range of radiative forcing that the new scenarios cover and the higher climate sensitivities in some of the new models compared to their CMIP5 predecessors. Spatial patterns of change for temperature and precipitation averaged over models and scenarios have familiar features, and an analysis of their variations confirms model structural differences to be the dominant source of uncertainty. Models also differ with respect to the size and evolution of internal variability as measured by individual models' initial condition ensemble spreads, according to a set of initial condition ensemble simulations available under SSP3-7.0. These experiments suggest a tendency for internal variability to decrease along the course of the century in this scenario, a result that will benefit from further analysis over a larger set of models. Benefits of mitigation, all else being equal in terms of societal drivers, appear clearly when comparing scenarios developed under the same SSP but to which different degrees of mitigation have been applied. It is also found that a mild overshoot in temperature of a few decades around mid-century, as represented in SSP5-3.4OS, does not affect the end outcome of temperature and precipitation changes by 2100, which return to the same levels as those reached by the gradually increasing SSP4-3.4 (not erasing the possibility, however, that other aspects of the system may not be as easily reversible). Central estimates of the time at which the ensemble means of the different scenarios reach a given warming level might be biased by the inclusion of models that have shown faster warming in the historical period than the observed. Those estimates show all scenarios reaching 1.5 ∘C of warming compared to the 1850–1900 baseline in the second half of the current decade, with the time span between slow and fast warming covering between 20 and 27 years from present. The warming level of 2 ∘C of warming is reached as early as 2039 by the ensemble mean under SSP5-8.5 but as late as the mid-2060s under SSP1-2.6. The highest warming level considered (5 ∘C) is reached by the ensemble mean only under SSP5-8.5 and not until the mid-2090s.

Abstract:
Increased attention towards threatening stimuli in both the external and internal environments is thought to be a factor in the causation and maintenance of pathological anxiety. Attentional biases for threatening information have been demonstrated in anxiety disorders, however the cortical mechanisms involved remain unclear. In this investigation, an Emotional Stroop task consisting of neutral, positive, depression-related and anxietyrelated words, was used to investigate attentional biases in 14 Panic Disorder patients and 32 psychiatrically healthy controls. The standard colour-word Stroop was also performed to determine whether any general cognitive deficits exist in Panic Disorder. Steady-state probe topography (SSPT), a brain electrical activity imaging methodology, was used to investigate participants' brain activity during performance of the tasks. It was hypothesised that Panic Disorder is associated with specific biases for disorder-specific information and thus patients would exhibit increased interference for anxiety-related words only, compared to neutral words. Mean reaction times for the Standard Stroop was similar for the two groups. For the Emotional Stroop task, neither group showed an interference effect for any emotional category. However, Panic Disorder patients performed the Emotional Stroop significantly more slowly than the Controls. The SSPT data suggest that the Standard and Emotional Stroop tasks are associated with different patterns of brain activity in the Control and Panic Disorder groups despite the similarities in the reaction time data. Specifically, the Standard Stroop was marked by strong temporo-parietal excitation in the Panic Disorder group only. In addition, anterior SSVEP patterns further differentiated between the Control and Panic Disorder groups. The most striking finding for the Emotional Stroop was strong sustained bilateral temporo-parieto-occipital excitation in the Panic Disorder group. In addition, a subgroup of the Controls exhibited increased interference for anxiety-related words and therefore the brain activity for this group and the remainder of Controls who did not show interference was analysed separately. It was found that the presence of interference for anxiety-related words was associated with right prefrontal inhibition prior to response. Other time-varying changes in the SSVEP further distinguished between the subgroup of Controls who showed an interference effect and those who did not.

Abstract:
CAMSAP 1 is a spectrin associated, Calmodulin regulated protein that is a member of a large ubiquitous family of cytoskeletal proteins, defined by a novel C-terminal domain, the CKK domain. The CAMSAP family member in the fruit fly Drosophila melanogastor is encoded by the gene short spindles4 (ssp4). Little is known about this gene but a role in microtubule dynamics has been shown in cultured cells. I have interrogated bioinformatics databases and compared Ssp4 with Human CAMSAP proteins and found many similarities, and some differences, between them. Using in situ hybridisation I show that ssp4 transcripts are expressed in the gut, head and central nervous system during embryogenesis. An antibody that recognises the Ssp4 C-terminus reveals expression throughout the embryonic development of the gut and nervous system, and in a discrete population of cells in the head. I have investigated the effects of two independent P-element induced mutant alleles of ssp4 and show that mutant flies die in late embryonic or early larval stages. Disruptions to the locus do not seem to affect the nervous system but mutants were found to have aberrant head involution. I present preliminary evidence that suggests this defect may be the result of reduced apoptosis in the embryo. Head involution is a complex process, dependent upon co-ordinated changes to cell shape and the movement of groups of cells from different origins. As Ssp4 is a multi-domain cytoskeletal protein that is required for embryonic development, it may play a role in processes that are common to these morphogenetic events.

Abstract:
Denna licentiatuppsats behandlar brottspreventiv samverkan på individnivå, vilket är ett relativt nytt fenomen i Sverige och Skandinavien. Ett specifikt arbetssätt, samverkan mellan skola, socialtjänst, polis och fritidssektor – SSPF – undersöks i studien och övergripande studeras hur idén om brottspreventiv samverkan i form av SSPF konstrueras och motiveras, hur den tolkas och omtolkas av samverkansparterna samt hur den omsätts i praktik. Det mer specifika syftet med studien är att undersöka brottspreventiv samverkan på individnivå som idé och praktik. Tre olika fokus eller aspekter på detta belyses: policy/struktur; organisation/profession och praktik/familj. De frågeställningar som besvaras i studien och som är kopplade till ovanstående fokusområden är följande: Hur har denna form av samverkan runt unga växt fram och hur motiveras den? Hur ser de organisatoriska förutsättningarna ut och hur upplevs SSPF av samverkansparterna? Slutligen hur interagerar företrädare för samhällets institutioner/ de professionella med familjen? Tre kommuner ingår i undersökningen. Empiriskt material har samlats in  genom dokumentstudie, intervjuer i grupp och enskilt med samverkansparterna i de tre kommunerna, genom observationer vid SSPF-möten samt genom en enkät som gick ut till 30 kommuner och stadsdelar i Sverige. Resultaten visar att en koppling finns mellan den allmänna samhällsutvecklingen i stort och brottspreventionens utveckling. Allmänt kan sägas att talet om brottsprevention idag handlar allt mindre om strukturella förklaringar och åtgärder. I stället talas alltmer om kontroll och effektivitet, vilket bland annat innebär tidiga upptäckter och snabba insatser. För att lyckas med detta behöver samverkan komma till stånd. Resultaten visar också att polisens roll i individriktad prevention har blivit viktigare och framträder som den tydligaste aktören i SSPFsamverkan. Gällande förutsättningarna för SSPF-arbetet visar studien att såväl organisatoriska förutsättningar som exempelvis stabilitet i organisationer och implementeringsmöjligheter, som möjligheter till informationsutbyte på individnivå mellan parterna spelar stor roll för arbetet. De professionella bildar allians där den gemensamma bilden av den unge skapar mening. En spänning mellan stöd och kontroll blir synlig i  SSPF-arbetet, likväl som en sorts likriktning, där poliser agerar  socialarbetare och socialtjänsten talar om mer kontroll. Allians bildas  också mellan professionella och föräldrar, vilket främst syftar till ökad  kontroll runt den unge, men också till att stärka stödet till den unges  föräldrar.

This dissertation deals with crime prevention co-operation targeted at the  individual level, a relatively new phenomenon in present Sweden and Scandinavia. A certain work model – SSPF, collaboration between school, social services, the police and the leisure sector – is chosen for the study. The study's purpose is to investigate crime prevention co-operation on individual level as idea and practice. To this end, different focuses are used: policy/structure; organization/profession and practice/family. The questions the study answers attached to the focus areas above are the following: How has this form of interaction around the young  emerged and how is it justified? What are the organizational conditions and how is SSPF experienced by collaborative partners? What does the interaction look like between those representing society´s institutions as well as between the professionals and the families? Three municipalities are examined in the study. The empirical material was collected through studies of documents; interviews, in groups and individually, with collaborative partners in the three municipalities; observations at SSPF-meetings and a survey that were sent to a number of municipalities and districts in Sweden. On an overall level, the results show that a clear link exists between the  general development of society at large and the development of crime prevention work. Generally it can be said that talk of crime prevention today is less focused on structural explanations and action, but rather increasingly concerns control and efficiency, including early discoveries and rapid reaction, which should be strengthened through collaboration at work. The role of the police in individually targeted prevention has become more important and they can be seen clearly as the most dominant party in the SSPF-interaction. Regarding the current conditions for SSPF-work, the study shows that both the organizational prerequisites (such as stability in organizations), and implementation (such as opportunities for exchange of information at the individual level between the parties) play a major role. The professionals form an alliance in which the common image of the young creates meaning. A tension between support and control becomes visible in the work, as well as a kind of uniformity – iso-morphism- whereby the police acting social workers and the social service talk about more control. An alliance is also formed between professionals and parents, aiming mainly at gaining increased control concerning the young person, but also at strengthening support to the parents. The professional´s quest for a new way of working to make it better for the target group becomes clear in the study. In conclusion: this kind of collaborative work within the area of crime prevention is complex, and this study is a contribution to a better understanding of the subject.

Abstract:
Throughout the last years, the service encounter has gone through drastic changes due to rapid technological developments. The research area of service marketing is therefore putting a stronger focus on the academic field of technology-infused service encounters. Marketers have moreover also started to implement self-service technology (SST) within their service encounters, in order enhance their service delivery. This phenomenon has also been visible within the hospitality industry, whereby the hotel industry has experienced an increasing adoption of SST encounters. Consequently, hotels’ implementation of SST kiosks has enhanced the hotel guests’ participation level within the service encounter. Therefore, this thesis aims to gather insights on the emerging SST customer roles, by investigating the guests’ attitude towards the SST encounter. This leads to the investigation of distinctive SST customer roles within hotels’ self-check-ins.   The choice of the research topic was driven by the fact that existing research about SST implementation in the service encounter, lacks an investigation of the customers’ perspective. Thereby, a research gap was identified that outlays the customers’ enhanced participation as service co-producers. Previous research has focused on investigating customers’ technology acceptance, rather than their own identification as co-producers. Thereof, this thesis will put an emphasis on hotel guests’ attitude towards SST, as a specific aspect of the technology acceptance process. Moreover, this thesis will focus its investigation on self-check-ins within hotels that do not incorporate a human interaction point for their guests. Consequently, in order to investigate the SST customer roles more thoroughly, this thesis will also consider the viewpoint of the hotel. Therefore, qualitative interviews among nineteen hotel guests and one hotel representative were conducted.   The findings of this thesis revealed that SST customer roles cannot be predetermined within a hotel self-check-in. Instead, the hotel guests define their own SST customer roles through a reflection upon their purpose of the hotel stay, expectations of the check-in encounter, arising special needs and perceived benefits of the self-check-in. This determines their individual ‘role file card’, which can be utilized into the proposed SST customer roles archetypes of: technology enthusiast, beneficiary, traditionalist and contradictor. In regard to that, it has been identified that the information provided prior to the hotel guests’ stay, influences the reflection upon their SST customer roles. Moreover, it was discovered that with their increased responsibility over the check-in process, the hotel guests identified themselves as co-producers. Therefore, the findings outlined that the guests would want the price of the hotel stay to reflect their increased involvement in the service delivery.   From a theoretical perspective this thesis bridged the identified research gap of investigating hotel guests’ attitude towards SST, in order to classify the different customer roles that arise within a hotel’s self-check-in. Moreover, the findings revealed practical implications for hotel managers in regards of the need to provide their guests with more information about the SST encounter. Thereby, hotel managers will be enabled to increase their guests’ satisfaction with the SST encounter, as the guests’ expectations would be coherent with the hotel’s offerings.

Abstract:
Public Self Service Technology (SST) has become an important part of our daily life. Advancement in technology and reduced hardware costs have motivated service providers to deploy public a SST for various important and complex tasks. Examples of such tasks include editing and printing confidential documents, performing monetary transactions, etc. These tasks requires a user to reveal his/her personal information to a public SST. The major problem while performing these tasks using a public SST is that the user has to deal with many surrounding factors like social density, privacy and security, which might affect his/her trust towards the SST and in turn the user might refrain from using it. This study aims to find different factors that can enhance user’s trust towards a public SST, encourage to use it and complete the task even if it requires user’s personal information.The in-depth interview method was adopted for the study to learn twelve interviewees’ experience with varied public SSTs that specifically handles personal information, in an urge to understand interviewees’ behaviour, underlying motivations and desires to use those public SSTs. Analysing the data collected from interviews, ten trust factors were found that emerge at various stages of interaction with a public SST. They were categorized into pre-interaction, on-interaction and post-interaction factors based on their time of interaction. Beyond the trust factors, three additional important factors have emerged from interview data, which motivates users to adopt public SSTs. They are usefulness, convenience and personality-based trust. The results may be valuable for researchers who are focusing on different aspects of trust and any public artefact as well as for service providers and designers to design a trustworthy public SST. Based on the results, some practical implications for designing public SSTs are also presented.
Offentlig självbetjäningsteknik (eng. Public Self Service Technology) har blivit en viktig del av vårt dagliga liv. Förbättring i teknik och minskade hårdvarukostnader har motiverat tjänsteleverantörer att distribuera offentliga SST för olika viktiga och komplexa uppgifter. Exempel på sådana uppgifter är att redigera och skriva ut konfidentiella dokument, utföra monetära transaktioner etc. Dessa uppgifter kräver att en användare delar med sig av personlig information till en offentlig SST. Det stora problemet med att utföra dessa uppgifter med hjälp av SST är att användaren måste hantera många omgivande faktorer som social täthet, integritet och säkerhet, vilket kan påverka personens förtroende mot SST och i sin tur kananvändaren avstå från att använda den. Följaktligen syftar denna studie till atthitta olika faktorer som kan öka användarnas förtroende mot offentliga SST, uppmuntra att använda dem och slutföra uppgifter även om det kräver användarens personuppgifter.En djupintervjumetod användes i studien för att lära sig om tolv testdeltagares erfarenhet av olika offentliga SST, specifikt de som hanterar privat information, i en strävan att förstå deltagarnas beteende, underliggande motivation och önskemål att använda dessa offentliga SST. Analys av de uppgifter som samlats in från intervjuer, upptäckte tolv förtroendefaktorer som uppstår vid olika stadier av interaktion med en offentlig SST. De var därför uppdelade i pre-interaktion, interaktionsoch post-interaktionsfaktorer. Från intervjuerna har ytterligare tre viktiga faktorer upptäckts som motiverar användarna att använda offentliga SST. De är användbarhet, bekvämlighet och personlighetsbaserat förtroende. Resultaten är värde-fulla för forskare som fokuserar på olika aspekter av förtroende och offentligaartefakter samt för tjänsteleverantörer och designers för att utforma en pålitlig offentlig SST. Baserat på resultaten presenteras också några praktiska konsekvenser för utformningen av offentliga SST.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Biology, February 2006.
Includes bibliographical references.
ClpXP and related ATP-dependent proteases are implements of cytosolic protein destruction. They couple chemical energy, derived from ATP hydrolysis, to the selection, unfolding, and degradation of protein substrates with the appropriate degradation signals. The ClpX component of ClpXP is a hexameric enzyme that recognizes protein substrates and unfolds them in an ATP-dependent reaction. Following unfolding, ClpX translocates the unfolded substrate into the ClpP peptidase for degradation. The best characterized degradation signal is the ssrA-degradation tag, which contains a binding site for ClpX and an adjacent binding site for the SspB adaptor protein. I show that the close proximity of these binding elements causes SspB binding to mask signals needed for ssrA-tag recognition by ClpX. The SspB dimer overcomes this signal masking by tethering itself and bound substrate to ClpX, via docking sites located in the dimeric N-terminal domain of ClpX. Because this N-domain dimer binds only a single SspB subunit, the ClpX hexamer can accommodate just one SspB dimer per hexamer. Other adaptor proteins that use these same tethering sites must compete with SspB for access to ClpXP. Substrates bearing ssrA tags with increased spacing between the SspB and ClpX binding elements are degraded more efficiently at low concentrations by ClpXP.
(cont.) This mechanism in which the adaptor first obstructs and then stimulates substrate recognition may have evolved to permit an additional level of regulation of substrate choice. SspB binding to ssrA-tagged substrate is a highly dynamic process, allowing rapid transfer of substrates from SspB to ClpX. Although the ClpX hexamer is composed of six identical polypeptides, individual subunits assume at least three distinct conformations. Using a hexamer that was engineered to prevent nucleotide hydrolysis, I show that some nucleotide-binding sites in ClpX release ATP rapidly, others release ATP slowly, and at least two sites remain nucleotide free. Occupancy of both the slow sites by ATP and the fast sites by either ATP or ADP is required to bind the degradation tags of protein substrates. The ability of ClpX to retain binding of substrate with ATP or ADP in the fast sites suggests that nucleotide hydrolysis in the fast sites, but not in the slow sites, will allow repeated unfolding attempts without substrate release over multiple ATPase cycles. My results rule out ATPase models including ClpX6eATP6 or ADP6 and also suggest that the enzyme hydrolyzes only a fraction of bound ATP in a single turnover event. Short peptide motifs of ClpX, known as IGF loops, interact with ClpP and change conformation as a response to nucleotide binding by ClpX.
(cont.) As ClpX varies its nucleotide content during the ATP hydrolysis cycle, it also varies its affinity for ClpP. Processing of substrates is coupled to the ATP-hydrolysis cycle of ClpX and appears to modulate ClpX's affinity for ClpP by changing how long each ClpX subunit spends in each nucleotide state.

Full text
Abstract:
The residual stress and distortion found in multi-pass welds are often influenced by the prescribed inter-pass temperature. In ferritic steel components, the severity of this influence is affected by solid-state phase transformation (SSPT) kinetics, which will depend on the overall heat input and cooling conditions. The development of an optimised welding procedure to mitigate weld residual stress (WRS) and distortion in these components can therefore necessitate an extensive test matrix, varying both preheat and inter-pass temperatures as well as the transient weld heat input. Computational parametric studies provide an opportunity to dramatically reduce the cost and time associated with the development of welding procedure specifications. Welding procedures can be simulated using validated modelling approaches to examine parametric sensitivity and gain insights into optimal conditions for a given welding task. In the present study, a three-pass tungsten inert gas (TIG) groove weld in SA508 Gr.3 Cl.1 ferritic steel is numerically investigated using the ABAQUS finite element code with a user defined subroutine to incorporate the effect of SSPT kinetics. Parametric sensitivity is assessed whereby a representative heat input is applied to simulate weld deposition for each pass, and the inter-pass temperature is varied to examine its effect on WRS and distortion in the weldment. The implications of the overall heat input on cross-weld microstructure are also presented using this approach.

Abstract:
Abstract Tomographic reconstruction of a wide range of materials can be accomplished via mechanical polishing serial-sectioning – alternately polishing away material and imaging the remaining polished surface with optical (or electron) microscopy. Under computer control it is possible to acquire 2-D images of hundreds of sections without user intervention and assemble them for 3-D visualization and measurements. In general, the resulting 3-D images permit significantly better understanding of the structure of complex systems than would be possible with a few strategically acquired 2-D images at various depths. Herein we report what we believe is the first general implementation of automated Serial-Section Polishing Tomography (SSPT) and reconstruction using light microscopy.

Abstract:
The Kimberlina Solar Thermal Power Station in Bakersfield, California, is AREVA Solar’s first North American solar thermal energy facility and an important showcase of AREVA’s Compact Linear Fresnel Reflector (CLFR) technology. Construction of a fourth solar steam generator (SSG4) was completed at Kimberlina in August 2010. At the time SSG4 represented AREVA Solar’s most current commercial technology, designed for direct superheat steam generation. SSG4 incorporates technology advancements that significantly enhance the AREVA Solar technology’s controllability, steam temperature and pressure capabilities as well as overall performance. After SSG4 was commissioned, AREVA Solar carried out an extensive performance test program on this advanced technology to formally evaluate and quantify its measured performance and compare that to the model-predicted performance. The performance testing included two specific tests. The first was the Steady State Performance Test (SSPT), which evaluated the technology’s steady-state performance over a two-hour period on multiple days. The second test was the Entire Day Performance Test (EDPT), which evaluated the technology’s performance throughout an entire day, including overnight losses, startup, mid-day performance (including steady-state, quasi steady-state and transients) and shutdown. The third test demonstrated the technology’s response to a simulated direct normal insolation (DNI) transient. AREVA Solar took great care to design and perform this testing in a standardized manner that would stand up to independent, expert observation and was consistent with established ASME performance test codes (PTC), where applicable. AREVA Solar plans to implement this testing methodology in future commercial plants and technology demonstrations. This paper documents in detail the performance testing methodology used to evaluate AREVA Solar’s new technology, including: • Test prerequisites; • Performance (both measured and modeled) calculation equations; • Environmental and optical surface measurement techniques; • Measurement test success criteria; • Uncertainty calculation and implementation. This paper also documents the measured testing results relative to the AREVA Solar internal modeled results including follow-up model validation.

Abstract:
Stochastic shortest path (SSP) is a well-known problem in planning and control, in which an agent has to reach a goal state in minimum total expected cost. In this paper we present the adversarial SSP model that also accounts for adversarial changes in the costs over time, while the underlying transition function remains unchanged. Formally, an agent interacts with an SSP environment for K episodes, the cost function changes arbitrarily between episodes, and the transitions are unknown to the agent. We develop the first algorithms for adversarial SSPs and prove high probability regret bounds of square-root K assuming all costs are strictly positive, and sub-linear regret in the general case. We are the first to consider this natural setting of adversarial SSP and obtain sub-linear regret for it.
