Abstract. Smart phones together with plethora of different sensors create a massive data collection system. This system can be also used for storing, analyzing, and broadcasting data. Data can be anything that can be metered or derived, from chemical compounds to traffic congestion to advertisement data to users’ activity or health statistics. Using the sensors already present in smartphones together with Bluetooth capable controller chips to add more sophisticated sensors, user creates an easily extendable monitoring system that does not require an internet connection. After embedded initialization programming, configuring and managing these chips can be done with a smartphone using Bluetooth communication stack. This study presents an Android-library for managing BLE peripherals and an app to collecting and store the recorded data. Bluetooth devices are scanned and connected through Bluetooth Low Energy interface and data is stored to persistent Room database.Tiivistelmä. Älypuhelimet yhdessä lukuisten eri antureiden kanssa luovat massiivisen järjestelmän tietojen keräämiseksi, tallentamiseksi, lähettämiseksi ja analysoimiseksi. Nämä tiedot voivat olla mitä tahansa kemiallisista yhdisteistä liikenteen ruuhkautumiseen ja mainosdatan esittämisestä käyttäjän aktiivisuuteen ja terveystilastoihin. Käyttämällä älypuhelimen valmiiksi olemassa olevia sensoreita ja yhdistelemällä niitä Bluetooth -ominaisuudella varustettuun ohjaussiruun kehittyneempien sensorien kanssa, käyttäjä saa luotua helposti laajennettavan monitorointi verkoston, joka ei vaadi internet yhteyttä. Käyttöönotettaessa tarvitun sulautetun ohjelmakoodin jälkeen, sensorilaitteita voi ohjata älypuhelimella, käyttäen Bluetooth radiota. Tässä tutkimuksessa esitellään Android-kirjasto BLE sensorien hallintaan, yhdistettynä tietojen keräämiseksi ja tallentamiseksi rakennettuun appiin. Bluetooth-laitteet skannataan ja liitetään Bluetooth Low Energy -rajapinnan kautta ja näistä luettu data tallennetaan paikalliseen Room-tietokantaan.

Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. However, the actions to reduce the nutrient input to the Baltic Sea have so farmainly been land-based. These actions seem to not be enough since the eutrophication continues tobe a problem for the Baltic Sea. Farming blue mussels has shown to have a mitigating effect on theeutrophication and could thus be a complementary action. Blue mussels are filter-feeding specieswhich means that they filter water for food and thus eat phytoplankton and accumulate nutrients atthe same time. When the blue mussels are removed from the sea, so is the nutrients accumulated inthe mussels, resulting in a mitigation of nutrients and thereby the eutrophication. Due to the brackishwater with the low salinity in the Baltic Sea, the blue mussels farmed there do not grow bigger thanaround 3 cm. This means that the mussels are not suitable for human food production and theharvested mussels need to be used for something else, even though the farming itself is anenvironmental action. Three possible mussel products from valorisation of the Baltic Sea blue musselshave been identified; producing mussel meal, biogas or compost.Region Östergötland is involved in a project, Baltic Blue Growth, with the main objective to study howto use mussel farming as an environmental measure and which of the three valorisation options is themost beneficial from an environmental perspective. This study is a part of their investigation to reachtheir goal and will study their mussel farm in St. Anna and the three valorisation options from anenvironmental perspective. The aim of this study is thus to investigate the net nutrient reduction froma mussel farm in the Baltic Sea in combination with the contribution to climate change. This is donefrom a life cycle perspective to include the valorisation of the mussels into the different productsmussel meal, biogas or compost. For this, an existing farm in the archipelago of St. Anna, Östergötland,Sweden is studied. The main results show that there is a nutrient reduction from the mussel farm andthis is not majorly affected regardless of which valorisation option that is chosen. However, the musselfarm does have an impact on climate change and the magnitude of the impact varies for the threevalorisation options. The results of the sensitivity analysis show that the result from the life cycle canbe improved with future improvements of the mussel farm and transportation. The nutrient reductioncan become larger and the impact on the climate change can be reduced. Outside the result from thelife cycle analysis it is discussed that there are other future improvement possibilities in the productionof the mussel products, which would impact the result. The mussel farm and the mussel products alsohave other positive impacts that is not included in the life cycle analysis but discussed in the study,such as increased water transparency, recycling of nutrients and reduction of over fishing. However,the mussel farm could also have negative impacts, such as emissions of microplastics and locallyincreased sedimentation which affect the hypoxia. Those are discussed in this study but the probabilityand possible impact of them are not fully investigated and need further research.

The objective of this thesis is to examine the evidence of and responses to shortages of skilled blue collar workers in the machining trades--tool and die makers and machinists--in the Montreal metropolitan region. The period studied is 1974 to 1981 and the study focuses on employer behaviour.<br>It was found that data available from government sources documenting the supply and demand for thee occupations are generally inadequate. The research underlines that one of the fundamental difficulties in compiling net supply and demand figures for these occupations is the pinning down of skill levels involved. Employers' definitions of skill are therefore analyzed.<br>This research indicates that organizational factors appear to influence the recruitment process as well as the choice of adjustment measures. It was found that employers dispose of and use many measures to respond to shortages. Specifically it was found that the adjustment process does not take place only through changes in wage rates. Rather employers will tend to favour adjustment measures that maintain existing arrangements within firms and preserve management discretion.

Nature-based tourism and recreation is a growing phenomenon around the world. In Australia, nature-based tourism represents an important part of the tourism sector and is to a large extent dependent on protected areas such as World Heritage areas, marine parks and national parks. While tourism and recreation can benefit protected areas, some are under pressure from visitation and marketing should play a role in managing visitor demand. To this end, a number of authors have suggested demarketing as a management tool to address situations of excess visitor demand, however, research on demarketing in protected areas is limited. To address this research gap, this thesis examines the use of demarketing in Australian national parks that face excess visitor demand using a case study on the Blue Mountains National Park. The thesis investigates factors that contribute to high visitor demand for the park, the use of demarketing to manage demand and factors that influence when and how demarketing is applied. Demarketing is that aspect of marketing that deals with discouraging customers in general or a certain class of customers in particular on either a temporary or permanent basis. In protected areas specifically, demarketing is concerned with reducing visitor numbers in total or selectively and redistributing demand spatially or temporarily. Six factors that contribute to high visitor demand for the national park were identified including the attractiveness of the park, its proximity to Sydney and the fact that the park is a renowned destination with icon sites. It was established that no holistic demarketing strategy is currently employed in the park and that the demarketing measures that are applied are not consciously used as demarketing. The measures used in the Blue Mountains National Park were discussed according to their association with the marketing mix components (4 Ps). Demarketing measures related to �product� include limiting recreational activities by defining specific areas where they can be conducted, limiting the duration of activities and closures of sites or features in the park. The measures related to �place� are the use of a booking system, limiting visitor numbers and group sizes, commercial licensing and limiting signage. Measures related to �price� are not extensively used in the park. The promotional demarketing measures applied include stressing restrictions and appropriate environmental behaviour in promotional material and nonpromotion of certain areas or experiences in the park. Importantly, these demarketing measures are not employed across the whole park or for all user groups, but are used for certain experiences in specific contexts and circumstances. Three types of factors influence the use of demarketing in the Blue Mountains National Park: pragmatic considerations, resource considerations and stakeholder interests. Pragmatic considerations include the feasibility and effectiveness of certain demarketing measures, which are influenced by the specific context of the national park. Resource considerations relate to financial, human and temporal resources and the findings suggest that a lack of resources influences and at times inhibits the use of demarketing measures. It was also found that various stakeholders have a profound influence on the use of demarketing measures. The stakeholder groups have diverse interests and therefore influence the use of demarketing in different ways by supporting or impeding certain measures. Based on the findings and limitations of this study, recommendations for government and future research are made. These emphasise among others the need for more consistent and comprehensive collection of visitor information to tailor management actions more effectively. It is also suggested that a more conscious and holistic application of demarketing measures may help to manage visitor demand to parks proactively to ensure that the resource remains for future generations.

What impact does the Swedish society have on the practice of Islam? That is the main topic of this thesis. As a result of migration, the distinction between a specific region and a culture or religion has been mixed. Islam is not just part of the Middle East but is more and more institutionalized in the Western, and the Swedish society. Sweden, which is one on the most secular countries in the world, has developed into a country where the view on religion have been privatized. Religion can be practiced, but not in public. This also has an impact on the individual’s practice of Islam. To grow up in a society where the Islam is dominated in the public space and migrating to a society where there is little public support for practicing your own religion does in many ways affect the expression of Islam. The thesis is based on interviews with ten individuals practicing Islam and living in Sweden,but who have been growing up in different societies. Through the interviews there has emerged a tendency that the visible/outer practice of Islam decreases and the non-visible/inner practice are becoming more apparent. In this thesis this is de-islamisation. For example, praying five times a day is an aspect of Islam that among some of the respondents is less focused on. There is not less of Islam, but the practice of Islam has changed in a way where most of the focus is on the non-visible part of Islam.

The Baltic Sea is the most polluted sea in the world. Its hydrological conditions and ongoing eutrophication are a high threat for marine biodiversity and ecosystems. Additionally, eutrophication has negative effects on the wellbeing of countries and their societies in the Baltic Sea Region (BSR). Actions to mitigate eutrophication in the Baltic Sea have been implemented through on-land measures in the last 40 years. Although the improvement in the marine environment is notable, it happens very slowly. In order to combat eutrophication, there is a need for a combination of on-land and in-situ measures. In this study, blue mussel farming practices are presented as one of the in-situ measures to combat eutrophication in the Baltic Sea. Blue mussel farming has been implemented in Sweden since the 1980s and has potential to not only mitigate the amounts of nutrients that accumulate in the sea but also brings a circular approach to resource use. In this study, stakeholders from four different sectors that are closely related to blue mussel farming practices and Baltic Sea issues have been interviewed with the aim of making a comprehensive analysis of stakeholder perceptions of blue mussel farming practices in the BSR. Interviewed stakeholders represent four different sectors - academia, entrepreneurs, municipalities and NGOs. A comprehensive analysis of stakeholders’ perceptions on blue mussel farming practises from environmental, social and economic perspective is presented. All interviewed stakeholders are actors in Sweden and represent Swedish perspective on blue mussel farming activities. Potential causes for different perceptions across sectors are discussed.
