This thesis investigates the role of marijuana use in labor productivity in the United States with the aim to contribute to the discussion and understanding of economic consequences of marijuana legalization. The data is sourced from various federal agencies to create a panel of 50 U.S. states and the District of Columbia for the period of 2005-2017. A panel data model with fixed effects is estima

Den utbredda gängkriminaliteten och bruket av vapen eller andra farliga föremål på offentliga platser är ständigt närvarande i den politiska debatten i Sverige. Frågor rörande vilka medel och befogenheter polisen har och bör ha återkommer frekvent och i diskussionen framkommer ofta referenser till Danmark och systemet med visitationszoner som där finns. En liknande, men inte identisk, lagstiftningThe widespread gang violence and the use of weapons in public spaces are often focal points in Swedish political debate. Questions regarding which means and authorities the police have and should have are raised frequently and references to Denmark and their system with ‘stop and search’ zones are often mentioned in the discussions. A similar, but not identical, legislation to the one in Denmark h

Background The widespread antibiotic resistance is an imminent problem in today’s world. As the number of antibiotic resistance cases increase, it is inevitable to discover alternate treatment options. Probiotics could be one of the potentially important avenues which could be exploited to treat antibiotic resistance and other infections. The holistic approach of probiotics in exerting their benef

“The code that guides the Path” Geosmin is a volatile metabolite that smells like the earthy odorant that is mostly predominant after a heavy rain fall; what produces this intensive surge of geosmin in the air is from the spore producing family streptomycetaceae. Not only do these bacteria produce a scent that most people find pleasant to smell, they also play a key role in modern society. Why th

As transistors in integrated circuits (ICs) are becoming smaller, faster and more, it has become harder to avoid malfunctioning. Embedded instruments are increasingly used to test, tune, and configure the transistors in ICs. IEEE Std.1149.1-2013 and IEEE Std.1687 standardize the access to these embedded instruments. IEEE Std.1687 enables reconfigurable scan networks which allow only desirable inst

Community resilience is a highly relevant topic and the focus of much contemporary research, however it has yet to be distilled down to an exact science. The current thesis applies a theoretical framework for community resilience as an analytical lens when investigating the community response to the Grenfell fire and tragedy of 14th June 2017. Of particular interest is to uncover what community re

This paper aimed to identify discourses and interpretative repertoires, used by the CIA to construct a narrative regarding terrorism when communicating with the public. This was done by analysing texts found on the official CIA website with discursive psychology methodology. Three main themes were identified, with thirteen subthemes. These related to how the CIA presented terrorists, terrorism, an

Idag finns mängder av kommersiella VST-syntar som modellerar klassiska analoga syntar men det finns lite publik forskning på området. Anledningen till att det är av intresse att efterlikna klassiska analoga syntar är att deras oscillatorers grundvågformer sällan är perfekta. Denna imperfektion ger anledning att undersöka och digitalt implementera klassiska analoga syntar för att ta reda på vad det

The role of private cars in urban areas is coming under increasing scrutiny. A growing number of municipalities are now implementing or exploring the potential of car-free city centres (CFCCs), defined zones in which car use is prohibited or severely restricted. Whilst CFCCs can deliver environmental, social and economic benefits for cities, businesses are routinely opposed to the introduction of

The demand for space cooling is rising. The increase in cooling demand can put significant strain on the electric grid since approximately 99% of air-conditioning and refrigeration loads worldwide are met with electricity. Many hot weather cities could benefit from district cooling (DC) systems to meet their growing cooling demand in an effective sustainable manner. Since these systems require sig

Insects play vital roles in almost every ecosystem and have high ecological, social as well as economic value. Human activity -most critical in urban environments- profoundly stress insect populations and habitats, regardless of their known benefits to society. Conserving insects in an urban context remains a topic predominantly for insect enthusiasts and revolves around preferred insects, such as

As a result of the current climate crisis, which reflects people's unsustainable consumer behaviour, there is an increased need for companies to apply sustainability strategies. One of the responses to the crisis is the increasing number of packaging-free grocery stores that have opened across Europe. These new stores have the intent of reducing waste by using, for instance, Circular Economy s

Car sharing (CS) is a growing phenomenon globally but its environmental implications are not yet fully explored. While many researchers agree that it could have multiple direct environmental benefits, indirect effects like carbon emissions induced through changed consumption patterns have been poorly explored. This thesis aims to quantify and compare consumption induced carbon emissions (CCE) of C

Connexins are proteins that make up the gap junctions that directly link the intracellular spaces of neighboring cells. Each gap junction is formed by the joining up or docking of two hemichannels in the cell membranes. It has been proposed that the gap junctions themselves or opening of hemichannels to the extracellular space may allow the spread of cytotoxic signals after injury, leading to prog

Cerebral Palsy (CP) is a disorder of movement that is caused before, during or soon after birth. CP affects movement and co-ordination caused by lack of muscle control by the brain [1], [2]. Stiff muscles, weak muscles, tremors and seizures as well as difficulties with swallowing are examples of symptoms in children with CP. Every year there are approximately 200 children born in Sweden that are a

“Only in the most technical sense is this a case about who may penetrate whom where. At a practical and symbolical level it is about the status, moral citizenship and sense of self-worth of a significant section of the community.” Justice Albie Sachs, National Coalition for Gay and Lesbian Equality and Another v Minister of Justice and Others 1999 (1) SA 6, para. 107 More than 70 years after th

Pupils tend to experience ‘attentional fatigue’ after persistently demanding their attentional system during school hours, resulting in decreased psychological well-being and a lack of attention, along with losses of other cognitive functions. Previous research found natural elements in a school environment to restore pupils’ depleted attentional system. The present study aimed at investigating na

Microbial decomposers breakdown soil organic matter, releasing carbon dioxide (CO2) to the atmosphere. This release of CO2 could therefore contribute to future climate change. However, microbial decomposers might also be affected by climate change, as for example the intensity and frequency of drought and rainfall events are expected to increase, resulting in more drying-rewetting (D/RW) events in

This study revolves around how the adult immigrants who live in Rosengård think and feel about living in this segregated area, the impact such place has on identity creation and how identity development is seen in the background of their integration into the Swedish society. In this study the qualitative method has been used – six interviews have been conducted with residents of Rosengård. On the
