The thesis addresses the debate about the impact of immigration policy on the socio-economic incorporation of immigrants. A distinction between rights-based and responsibility-based models of incorporation is made and the effect of a feature of the responsibility-based model, temporary residence permits, on socio-economic incorporation is studied. Empirically, a policy change in Sweden that entailed a shift from permanent to temporary residence permits is explored through individual-level register and survey data. The thesis uses a two-folded methodological approach: a traditional regression approach and a fuzzy regression discontinuity design. The composition of the available data motivates the two-folded approach. The limitations of both approaches are discussed, and the results compared and contrasted. The results indicate that immigrants with temporary residence permits work more than immigrants with permanent residence permits. This result should however be interpreted with caution due to the limitations of the approaches used. The results do not show a significant effect oftemporary residence permits on an educational outcome, Swedish tuition, nor on a labour market activation outcome, participation in labour market programmes. The predictions that immigrants with temporary residence permits study less and participate in labour market programmes more than immigrants with permanent residence permits are thus not supported.

Det här projektet undersöker vad hemkänsla innebär och hur förhållandet mellan en bostad och ett hem ser ut. Hemmet är till skillnad från bostaden något som inte kan formges. Projektet undersöker därför hur en bostad kan utformas för att ge goda förutsättningar för att utvecklas till ett hem, ett monument över människorna som bebor det. Projektet innefattar såväl en teoretisk del, i form av en litteraturstudie, som en praktisk del, i form av utformandet av två stycken småhus i Dalarna, Sverige. En viktig inspirationskälla för projektet är ”The Poetics of Space” av den franske filosofen Gaston Bachelard, som belyser hemmets själsliga dimensioner. I projektet görs ett försök att koppla samman de teoretiska och praktiska aspekterna av bostaden/hemmet, vilka i stor utsträckning behandlas separat inom den forskning som ligger till grund för projektet. I strävan efter att formge bostäder som är väl anpassade till platsens förutsättningar studeras dessutom lokal timmerarkitektur, liksom den traditionella stugans utveckling. / This project investigates the meaning of “feeling at home” and the relationship between a residence/accommodation (the English language lacks a more precise translation for the Swedish word bostad) and a home. The residence is something that can be designed, whereas the sensation of feeling at home is something that emerges over time. Therefore, the project investigates how a residence can be designed to provide good conditions for it to be transformed into a home. The project is constituted of a theoretical part, in the form of a literature study, as well as a practical part, which consists of the designing of two single family houses, to be placed in Dalarna, Sweden. An important source of inspiration for the project is “The Poetics of Space”, written by the French philosopher Gaston Bachelard, which highlights the existential dimensions of the residence. The project attempts at combining the theoretical and practical aspects of residence and home, which are usually treated separately in this field of research. Furthermore, in the pursuit of designing residences that are well adapted to the conditions of the site, local timber architecture and the development of the traditional cottage/hut are explored.

Can I create my own design companion? My own design AI? How far do I go using the machine? What are the poetics of machine learning? This thesis is about exploring art and artificial intelligence, specifically machine learning which is the study of computer algorithms that improve through experience. The core thing of what machine learning does is to find patterns in data to then use those patterns to in some way predict the future.  I define a machine which works and generates images according to the given rules. The rules are set in time and in data. The decision, however, as in all creative processes, is up to the creator (in this the architect) so it is as much a part of the creation as the setting up of the data. The method is a mix of my own personality and imagination and the impersonal machine (my computer).  With me during the process, I found inspiration from other creators working with machines in different experimental ways that diverge from the original purpose of their machine/tool. The project is an investigation of contemporary technologies where I try to understand my tool through a series of experiments.

Autism diagnoses are on the rise and part of the explanation is that society is making increasing demands on us and our brains. Autism is largely about how we perceive and interpret our surroundings, so there should be opportunities to support people with autism through thoughtful architecture to reduce stress levels and save energy. What is autism-friendly architecture and what might it look like?  In this project, I have designed a service residence (a type of LSS accommodation) for adults diagnosed with autism. By reviewing relevant literature and reference projects on the topic, I have tried to find keys on how to design a home that can support a person with autism. The overall objectives of the design are to reduce stress, enhance the individual's independence and support social interaction. The architectural aspects I have mainly worked on to achieve this are daylight, views, visual connections and boundaries and the organisation of the programme. Since people with autism have, among other symptoms, a different sensory experience often being hyper- or hypersensitivity to sensory input, an autism-friendly architecture is very much about designing for the senses.  The conclusion is that accommodation suitable for a person with an autism diagnosis can suit most people. It’s more about avoiding certain things that may be experienced as disturbing in different ways by people with autism, rather than adding special features.

Plant-derived protein such as pea protein is a promising replacement for animal protein and is becoming popular in recent years because of its high nutritional value and potential reduction of environmental footprint. However, the increasing demand for plant-derived proteins is accompanied by the increase of wastes during protein processing such as wastewater containing dilute protein content, which may raise the cost for the downstream processing. Therefore, there is an emerging need to develop novel processing strategies to reduce waste while valorizing useful ingredients. Several researchers suggest that foam fractionation technology can be a viable approach to extract and concentrate protein from dilute wastewater effluent. This technology has already been applied to the chemical and food industry for the extraction of surfactant and animal proteins from wastewater. To design and apply foam fractionation to the plant-derived protein industry, fundamental knowledge on foaming properties of dilute plant-derived protein solution is needed and is currently lacking. Therefore, the objective of this thesis is to advance a fundamental understanding of the foaming properties of dilute pea protein solutions (protein concentration ≤ 1wt%). To achieve the objective, a multiscale approach is used, which is comprised of a detailed investigation of both bulk and interfacial properties of pea protein solutions and foaming properties such as foaming capacity and stability with the help of bubble structure and foam volume kinetics. The focus of this thesis is on the effect of protein concentration. Results demonstrate that protein adsorption kinetics can be characterized by four distinctive regimes: lag phase, diffusion-limited regime, transitional regime, and conformation change regime, which are highly dependent on the protein concentration. However, apparent viscosity is less affected by the protein concentration. Results also show that depending on the protein concentration, two regimes can be distinguished for foam capacity and foam stability. For the first time, these regimes can be rationalized by contrasting characteristics times of protein adsorption kinetics and processing time scale – residence time of bubbles during the foam formation. New findings from this fundamental research will shed light on the control and optimization of foaming properties of plant-derived protein solutions for applications ranging from food processing design to food product development.

College students are at higher risk to develop problematic internet use (PIU) than the average person and that risk may negatively impact their college success. Since students with PIU are not violating policies, they are not being identified as having a problem through the student conduct process like other students with problems such as alcohol abuse. While research on PIU is still in its infancy, the research that has been conducted indicates that PIU is a growing problem with no agreed upon definition, diagnosis or treatment. The main purpose of this study was to determine the extent that PIU and PVP exists in residence halls on college campuses. The theoretical framework was the addiction syndrome theory (AST) and is the only current model that can be used to explain all addictions, including behavioral addictions which is the category of addiction the PIU falls under. The main measurement tool was the Young internet addiction test (IAT) which measures levels of online activity. The results of this study were inconclusive. There was a low correlation between online activity and academic performance as measured by academic probation. The weak relationship indicates that PIU may be an issue for college students and therefore may need to be considered when administrators are making policies. Whether the AST proves to be a valid conceptual framework for studying PIU and other addictions remains to be seen. The results here were inconclusive and therefore further research involving AST is needed before drawing any real conclusions.

Job satisfaction of entry-level student affairs professionals has been an issue of interest to researchers and practitioners alike since at least the 1980s. A high turnover of housing and residence life live-on and live-in (LO/LI) professionals has led to a curiosity for the reason. Investigation into job satisfaction of these professionals is an ideal way to determine ways to help retain LO/LI professionals and enhance their overall job satisfaction. In this study, the personal demographics, institutional demographics, and amenities provided to entry-level housing and residence life professionals holding LO/LI positions, and what impact, if any, they had on job satisfaction were examined. Job satisfaction was measured by two separate means, both based on the theoretical framework, the Job Characteristics Model. A web-based survey was distributed to approximately 9,000 members of the Association of College and University Housing Officers-International, asking for all LO/LI professionals to complete the survey. Personal demographics slightly affected job satisfaction, and institutional demographics were not related to job satisfaction. Amenities were the strongest predictors of job satisfaction among the three areas examined. Specific amenities such as meal plans, reserved parking, and flexible work hours had a more significant impact on job satisfaction than others.

Two sets of triplicate pilot algal raceway ponds (1000-L, 0.30-m deep, paddle wheel mixed) were operated for 14 months at a California wastewater treatment plant to treat wastewater and generate algal-bacterial biomass as biofuel feedstock. Two experiments were run to determine the effect on biomass productivity of (1) hydraulic residence time (HRT: 2, 3, 4, or 4.5 days) and (2) feeding schedule (18 small pulses during 8 AM-4 PM [diurnal] versus 20 large pulses during 4 AM-12 AM [diel]). The target productivity was at least 20 g volatile suspended solids per m2 of pond per day. Additional output variables were followed during the experiments: treatment performance and the effectiveness of biomass harvesting though bioflocculation. Productivity was consistently higher in ponds with a 2-d HRT versus longer HRTs. Average productivity for the 2-d HRT ponds and the variable-HRT ponds (3.6-d average HRT) were 30.1 and 23.4 g/m2-d, respectively. Productivity data collected during the feed regime experiment were highly variable, and average productivities were the same at 26 g/m2-d. During both experiments, both pond sets exceeded the target of 20 g/m2-d on an annual basis. During the hydraulic residence time experiment, the average pond productivity throughout the HRT experiment for the 2-d HRT and 3-d HRT ponds were 30.1 and 23.4 g/m2-d, respectively. Settling efficiency was high for both 2- and 3-d HRT ponds with average turbidity removal of 87-89%. However, total ammonia nitrogen (TAN) concentrations in the 2-day HRT pond effluent were 50-94% higher than in the 3-d HRT pond effluents, although effluent TAN concentrations in both ponds were approximately the same during mid-summer. Furthermore, effluent biochemical oxygen demand (BOD5) concentrations were similar, with the supernatant of Imhoff cones settled for 24 hours containing 24-27 mg/L BOD5 (81-92% removal). In general, the 3-d HRT ponds provided better treatment than the 2-d HRT ponds. During the feeding regime experiment, no productivity or BOD5 removal differences were evident. However, the 3-d HRT ponds had consistently 8 mg/L more effluent TAN than the 2-d HRT ponds.

With the world's population growing at a rate faster than the rate at which natural resources are being replenished, the challenge for governments and the world's citizens is how to conserve resources in order to provide a sustainable level of natural resources for the future. Conserving natural resources includes educating the citizens of the world on the connection between natural resource depletion and their levels of consumption of resources, such as energy and water. To help alleviate the increasing burden the world's growing population is placing on natural resources, sustainability should be a part of college students' education in their field of study and in preparing them to become good citizens. This education should take place in the classroom and other activities, including athletics, community organizations, and in their residence life. Teaching students living in on-campus residence halls conservation activities provides information that students can use in their private lives when setting up their own households. On-campus residence halls also provide an opportunity to evaluate any gender differences related to conservation activities since the demographics of the residence halls vary from all-female, to co-ed, to all-male students. Virginia Polytechnic Institute and State University (Virginia Tech) was the location for a study on promoting environmentally-relevant behavior (ERB) among students residing in on-campus residence halls. The objective of this study was to investigate the relationship between the use of educational strategies and natural resource consumption by promoting ERB among students living in the residence halls during the spring and fall semesters of the 2009 calendar year. Using the literature on promoting ERB, five different strategies were designed for promoting water and electricity conservation. Each strategy involved different stimuli to promote student participation in ERB. The information provided the students included reasons why ERB was important and specific actions to take to conserve resources. In three of the strategies, students were provided the results of their conservation efforts monthly during the study period. The Virginia Tech Office of Residence Life provided detailed information for the 49 on-campus residence halls, including buildings' characteristics such as heating and cooling methods, age, construction, renovation history, square footage, if the buildings contained offices or classrooms, and student population figures. Variability among the buildings was eliminated by comparing these differences, and then a random numbers table was used to assign each of the buildings to one of the five different groups. The strategy for each group was applied to four residence halls -- two dormitories and two Greek Houses, for a total of twenty buildings. In each strategy more stimuli were applied in an effort to produce higher consumption reductions. The Virginia Tech Office of Facilities provided four-years historical electricity and seven-years historical water usage, and provided monthly usage for each building during the study period. Electricity consumption reduction was promoted in all twenty halls but water consumption reduction was promoted only in the dormitories, as the University was unable to track water consumption for any one individual Greek House. The historical data showed that water usage per student was higher in most of the female-occupied dormitories, but no statistical difference was seen with regards to historical electricity usage and gender. Percent change in per student usage — kilowatt hours for electricity and gallons for water — was the calculation used to determine change in ERB. The results of this research showed a general relationship between educational strategies and natural resource consumption reduction over both study periods. However, except for the Greek-House Spring semester results, no statistical significant difference was found between any of the different study groups. Electricity reductions were achieved in seventeen of twenty residence halls during the first semester and in all but one residence hall during the second semester. Water reductions were achieved in five of ten dormitories during the first semester and in six of nine dormitories in the second semester. However, the use of more strategies did not lead to a higher percentage of reductions. During the first semester, a statistically significant difference was found in water usage and gender and the difference did not support a female predisposition for ERB. Decreases were achieved in excess of 10% in the male-occupied dormitories, but only a minimal reduction or increases were achieved in any of the dormitories that included female residents. After the first month of the second semester, similar results were seen relative to gender, so additional posters and prompts were placed in the female-occupied dormitories. As a result, water reductions were achieved in six dormitories with only small increases in the other three, and the semester final results did not show a statistical significant difference between genders. The lack of statistical difference between the study groups could be a result of contamination, the active environmental organizations on campus, or an observational effect. The study was contaminated within the first two weeks of the study period when all residence halls across campus learned of the research and requested their inclusion in the study. Since, the residence halls in the control groups were advised of their inclusion in the study, the students may have demonstrated ERB because of the knowledge they were being observed. A survey sent to the students living in the study residence halls revealed that 94.6% of the students had knowledge of the study, and that 77% participated in ERB. Students showed a propensity for ERB when they were informed on their consumptive behaviors' effects on natural resource depletion, and by being provided with actions they could take to change their behaviors. This research did not show that adding strategies of feedback and group leaders to information increased the percentage of consumption reductions in college students residing on Virginia Tech's campus. / Master of Science
