The aim of this one-year master thesis in archival science was to examine how municipalities take regulations concerning public records into account when they use Facebook.
Another aim was to examine the involvement of archivists, registrars or similar staff in the management of the regulations. Since Swedish archival theory and practice has a close connection to the application of these regulations, such an examination was hopefully going to reveal tendencies of importance for archival science. The method used to collect information was a web questionnaire and the result was based on answers from 21 municipalities with an official Facebook page.
The questionnaire showed that six of the municipalities regarded documents originating from their Facebook page as public records. Three did not, and a large group had not yet decided how to treat these documents. Only three municipalities did archive documents from Facebook. The involvement of archivists, registrars and similar personnel was generally very small, even though regulations concerning public records had more often been taken into account in the municipalities that had informed this personnel about the use of an official Facebook page.
The difference in management between the municipalities was together with the demand for national guiding principles indicating difficulties in applying the regulations to social medias like Facebook.
The fact that most of the municipalities that had taken the regulations into account had come to the conclusion that Facebook generated public records, together with the fact that national guiding principles presented during the work with this thesis had the same interpretation, indicated that documents originating from Facebook will be a part of Swedish public records in the future.
The difference in management and the demand for guidance also indicated a need for better division of responsibilities and a more active approach in the future, to ensure that the regulations concerning public records are taken into account early and correctly when authorities starts to use new medias. Accident models and analysis methods affect what accident investigators look for, which contributory factors are found, and which recommendations are issued.
The main issue addressed in this paper is the comparison of the established multi-linear method STEP with the new systemic method FRAM and which new insights the latter provides for accident analysis in comparison to the former established multi-linear method. Since STEP and FRAM are based on a different understandings of the nature of accidents, the comparison of the methods focuses on what we can learn from both methods, how, when, and why to apply them.
The main finding is that STEP helps to illustrate what happened, involving which actors at what time, whereas FRAM illustrates the dynamic interactions within socio-technical systems and lets the analyst understand the how and why by describing non-linear dependencies, performance conditions, variability, and their resonance across functions. A novel arc heat treatment technique was applied to design a uniquely graded super duplex stainless steel SDSS , by subjecting a single sample to a steady state temperature gradient for 10 h.
The microstructure was characterized and functionality was evaluated via hardness mapping. A schematic diagram, correlating information about phase contents, morphologies and hardness, as a function of exposure temperature, is introduced for evaluation of functionality of microstructures.
We have recently documented that trisomy 21 mosaicism is common in human foetal ovaries. On the basis of this observation we propose that the maternal age effect in Down syndrome DS is caused by the differential behaviour of trisomy 21 in relation to disomy 21 oocytes during development from foetal life until ovulation in adulthood.
The net effect of this preferential elimination will be an accumulation of trisomy 21 oocytes in the ovarian reserve of older women. We here highlight the implications of this Oocyte Mosaicism Selection OMS model with respect to the prevalent view that the maternal age effect is complex, dependent on many different biological and environmental factors.
We examine conclusions drawn from recent large-scale studies in families, tracing DNA markers along the length of chromosome 21q between parents and DS children, in comparison to the OMS model. We conclude that these family linkage data are equally compatible with the maternal age effect originating from the accumulation of trisomy 21 oocytes with advancing maternal age.
One relatively straightforward way to get to grips with what is actually going on in this regard would be to compare incidence of trisomy 21 oocytes and their pairing configurations in foetal ovaries with that in oocytes at the meiosis I stage from adult women.
Residents in marginalized areas tend to show a lower level of confidence in the criminal justice system and carry out police reports and testimonies to the criminal justice system to a lesser extent than residents in other areas.
In this scientific essay, a qualitative study is conducted to analyze the disinclination to leave testimonies and report crimes in marginalized areas, along with researching possible ways to improve the residents relationship with the criminal justice system.
The sample group for the study is advocates in non-profit organizations operating in marginalized areas. Furthermore, our findings show that an admittance of the existence of racism within the justice system, increased communication, cultural competence, and safe meeting places are believed to improve the relationship between the residents and the criminal justice system. This is a study of qualitative method that aims to investigate how compulsory school students perceive the content of Visual Art Education and the relevance of art education.
The study is based on empirical methods that consists of semi-structured interviews with a total of 12 students in grades 6 and 9. The theoretical framework of the study is based on a sociocultural perspective which describes that it is through communication and interaction with others that the individual acquires knowledge and skills.
The theoretical starting points for the study are supported by the concepts of visual culture, visual literacy and Vygotskijs concepts of creativity and imagination with the assistance of contemporary research that describes the concepts from the perspective of a modern-day society. Furthermore, the study uses the cultural circuit from Hall and photo elicitation from Rose as analytical tool to analyze the participants perceptions about Visual Art Education.
The results of my study show that Visual Art Education still represents something that is more similar to a traditional view of artist work, with a focus on techniques and materials. This shows the participants narrow view of how abilities linked to visual literacy are relevant in a modern society.
The knowledge contribution added to the problem area and previous research is a deeper understanding of how the participants perceive the relevance of Visual Art Education. The study is important and relevant for the teaching profession, as students need to be made more aware of the breadth and relevance of Visual Art Education.
From this content it can be deduced that the abilities that students must acquire through visual arts education are about so much more than just drawing. It is also important that teachers gain insight and understanding of how students perceive the relevance of Visual Art Education for them to be able to move forward. This thesis presents the development of integrated silicon photonic devices.
These devices are compatible with the present and near future CMOS technology. High-khorizontal grating couplers and waveguides are proposed. This work consists of simulations and device design, as well as the layout for the fabrication process, device fabrication, process development, characterization instrument development and electro-optical characterizations.
The work demonstrates an alternative solution to costly silicon-on-insulator photonics. The proposed solution uses bulk silicon wafers and thin film deposited waveguides. Back-end deposited horizontal slot grating couplers and waveguides are realized by multi-layers of amorphous silicon and high-k materials.
The achievements of this work include: A theoretical study of fully etched slot grating couplers with Al 2 O 3 , HfO2 and AIN , an optical study of the high-k films with spectroscopic ellipsometry, an experimental demonstration of fully etched SiO2 single slot grating couplers and double slot Al 2 O 3 grating couplers, a practical demonstration of horizontal double slot high-k waveguides, partially etched Al 2 O 3 single slot grating couplers, a study of a scheme for integration of the double slot Al 2 O 3 waveguides with selectively grown germanium PIN photodetectors, realization of test chips for the integrated germanium photodetectors, and study of integration with graphene photodetectors through embedding the graphene into a high-k slot layer.
From an application point of view, these high-k slot waveguides add more functionality to the current silicon photonics. The presented devices can be used for low cost photonics applications. Also alternative optical materials can be used in the context of this photonics platform. With the robust design, the grating couplers result in improved yield and a more cost effective solution is realized for integration of the waveguides with the germanium and graphene photodetectors.
We calculate the Josephson current density j phi for a Weyl superconductor-normal-metal-superconductor junction for which the outer terminals are superconducting Weylmetals and the normal layer is a Weyl semi metal.
We describe the Weyl semi metal using a simple model with two Weyl points. The model has broken time-reversal symmetry, but inversion symmetry is present. We calculate the Josephson current for both zero and finite temperature for the two pairing mechanisms inside the superconductors that have been proposed in the literature, zero-momentum BCS-like pairing and finite-momentum FFLO-like pairing, and assuming the short-junction limit. For both pairing types we find that the current is proportional to the normal-state junction conductivity, with a proportionality coefficient that shows quantitative differences between the two pairing mechanisms.
The current for the BCS-like pairing is found to be independent of the chemical potential, whereas the current for the FFLO-like pairing is not. This thesis aims to contribute to the understanding of how we better support teaching and learning of undergraduate chemistry to make it meaningful and intelligible for students from the outset. The thesis is concerned with examining the interactions between student, specific content and teacher in the undergraduate chemistry classroom; that is, the processes making up the three relations of the didactic triangle.
The data consists of observations of students and tutors during problem-solving activities in an introductory chemistry course and interviews with graduate students.
Systematic analyses of the different interactions between the student, the chemistry content, and the tutor are made using the analytical tool of practical epistemology analysis. The main findings of the thesis include detailed insights into how undergraduate chemistry students deal with newly encountered content together with didactic models and concrete suggestions for improved teaching and for supporting continuity and progression in the undergraduate chemistry classroom.
Specifically, I show how students deal with the chemistry content through a complex interaction of knowledge, experiences, and purposes on different levels invoked by both students and tutors as they interact with each other. Moreover, the tutor sometimes invoked other purposes than the ones related to the task at hand for connecting the activity to the subject matter in general.
These purposes were not always made continuous with the activity which resulting in confusion among students. The results from these analyses were used for producing hypotheses and models that could support continuity and progression during the activity. The suggested models aim to make the content more manageable and meaningful to students, enabling connections to other experiences and purposes, and helping teachers and tutors to analyze and reflect on their teaching.
Moreover, a purpose- and activity-based progression is suggested that gives attention to purposes in chemistry education other than providing explanations of chemical phenomena. A general conclusion is that detailed knowledge about the processes of teaching and learning is important for providing adequate support to both undergraduate students and university teachers in the chemistry classroom.
In this paper, we discuss the well-known teaching challenge of how to provide undergraduate students with basic chemistry knowledge without making them experience these basics as meaningless and unintelligible. First, we situate the challenge in a classic dilemma: should we teach the necessary basic facts before the chemical explanations or should the explanations be taught before or in parallel to these facts?
Here we draw on examples from interviews with graduate students reflecting on their experiences regarding their studies at the undergraduate level. Second, we suggest a way out of the dilemma, through a shift in perspective from the typical progression of facts and explanations towards a purpose and activity-based progression.
We conclude with a discussion of implications of such a shift for university chemistry education together with suggestions for future research. Anthropomorphisms are widespread at all levels of the educational system even among science experts.
Findings suggest that students invoked anthropomorphisms alongside technical relations which together produced more or less chemically appropriate explanations. The implications of this study refer to the need to deal with anthropomorphisms explicitly and repeatedly as well as to encourage explicit connections between different parts of the explanation - teleological as well as causal.
We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical epistemology analysis PEA. The results show that the ability to make relevant distinctions between the different parts of a molecule for solving the problem, even with the guidance of the tutor, seemed to be challenging for students.
These shifts were connected to both purposes that were specific for solving the problem at hand, and additional purposes for general learning of the subject matter, in this case how to assign oxidation states in molecules.
The students sometimes could not follow the additional purposes introduced by the tutor, which made the related distinctions more confusing. Our results indicate that in order to provide adequate support and guidance for students the tutor needs to consider how to sequence, move between, and productively connect the different purposes introduced in a tutor-student interaction.
Further recommendations drawn from this study are discussed as well. We document the discovery of an active, shallow, seafloor hydrothermal system known as the Seven Sisters Vent Field hosted in mafic volcaniclasts at a mid-ocean ridge setting. Up to deg C phase-separating fluids vent from summit depressions in the volcano, and from pinnacle-like edifices on top of large hydrothermal mounds.
The hydrothermal mineralization at Seven Sisters manifests as a replacement of mafic volcaniclasts, as direct intraclast precipitation from the hydrothermal fluid, and as elemental sulfur deposition within orifices.
Barite is ubiquitous, and is sequentially replaced by pyrite, which is the first sulfide to form, followed by Zn-Cu-Pb-Ag bearing sulfides, sulfosalts, and silica. A deltaC value of In view of the fact that most of the synthetic refrigerants, in case of leakage or release, are harmful to the environment by contributing in global warming or depleting stratospheric ozone layer, many research works have been done recently to find alternative refrigerants posing no or negligible threat to the environment.
Although ammonia has been used for many years in large industrial systems, its application in small units is rare. The heat pump is expected to produce enough heat to keep a single-family house warm in Sweden and to provide tap hot water for the house. After successful completion of this project, it is planned to install the heat pump in a house to test it throughout a heating season to study its performance in real working conditions.
Since ammonia is flammable and toxic in high concentrations, the refrigerant charge is tried to be kept low in the heat pump to reduce the risk of fire or poisoning in case of unwanted release of refrigerant to the surroundings. The compact design of the heat pump helps reducing the refrigerant charge. Besides, considering the limited space normally reserved for installation of a heat pump in a house, the compact design of the heat pump is necessary.
This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts.
In addition to the environmental impacts associated with energy consumption, the vapor-compression systems contribute in global warming due to the release of their gaseous refrigerants into the atmosphere. As an alternative technology for near room-temperature applications, magnetic refrigeration is proposed by some researchers to eliminate the release of gaseous refrigerants into the atmosphere and to reduce the energy consumption.
This thesis is a compilation of a number of studies done on magnetic refrigeration for room-temperature applications. In the first study, the environmental impacts associated to magnetic refrigeration are looked at closely through a life cycle assessment.
The life cycle assessment indicates that because of the environmental burdens related to the rare-earth materials used in magnetic refrigeration, the reduction in the environmental impacts is not guaranteed by switching to magnetic refrigeration technology. Accordingly to avoid the extra environmental impacts the magnetic refrigeration systems should use magnetic materials frugally, which requires an optimized design. In addition, operation with higher efficiency compared to vapor-compression systems is necessary to have environmental advantages, at least in some impact categories.
A practical method to optimize the design of magnetic refrigeration systems, e. Such a software model of the magnetic refrigeration system is developed and validated in this project. In developing the model one goal is to add to the precision of the simulated results by taking more details into consideration. This goal is achieved by an innovative way of modeling the parasitic heat transfer and including the effect of the presence of magnetocaloric materials on the strength of the field created by the magnet assembly.
In addition, some efforts are made to modify or correct the existing correlations to include the effect of binding agents used in some active magnetic regenerators. Validation of the developed software model is done using the experimental results obtained from the prototype existing at the Department of Energy Technology, KTH Royal Institute of Technology.
One of the parameters that can be modified by the developed software model is the choice of the magnetocaloric materials for each layer in a layered active magnetic regenerator.
Utilizing the software model for optimizing the choice of the materials for the layers reveals that materials with critical temperatures equal to the cyclic average temperature of the layers in which they are used do not necessarily result in the desired optimum performance.
In addition, for maximizing different outputs of the models, such as energy efficiency or temperature lift sustained at the two ends of the regenerators, different choice of materials for the layers are needed.
