Nigeria is, by population, the largest country in Africa and their economic growth will be a key part in the world reaching the goals of eradicating poverty. This paper investigates the economic growth performance of Nigeria and the relationship between oil and the GDP performance by using growth accounting, ARIMA, VAR and VEC models. Through the ARIMA and VAR models, the GDP is forecasted until 2

I mars 2020 rasade Tarfalahallen i Kiruna. Idrottshallens takkonstruktion bestod av långa underspända limträbalkar upplagda på limträpelare. Balkarna var underspända med hjälp av två trycksträvor som stöttades med dragband av stål och anslutningen mellan trycksträvorna och balken bestod av spikförband. Statens Haverikommission (SHK) har en pågående utredning kring raset, och har hittills bland annDuring March of 2020 a large-span sports arena, Tarfala hall, built 2015, collapsed in northern Sweden. The main load-bearing girders with a 54 m span, were high and slender glulam beams supported underneath by a cable system via vertical struts. Investigations concluded that the failure was initiated by lateral buckling of the struts and slender beam, in spite of lateral stabilization by a corrug

Today, we are creating and building more than ever. While buildings rise from the horizon, the consumption of building materials increases massively. More than 22% of global carbon dioxide emissions come from the consumption of building materials such as concrete, steel, and aluminum, etc. 55% of embodied carbon in a conventional building is in the structure and substructure (Smedley, 2019). Hence

This report covers the development process of finding the best attach method for a plastic cover to a metal chassis of a sensor. Several manufacturers of electronic equipment use screws as a semi-permanent way of attaching a cover to their product. However, this method is not always appreciated as it takes up volume in the product and makes the exterior of the product unattractive. The project has

This thesis was performed in collaboration with Phoniro AB, that develops digitally unlocked products that are mainly used in home care service. The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuri

The study is about architecture which helps restore disconnected relationship. The site is an empty military base which had been occupied by the U.S army right after the Korean War and has been physically and emotionally disconnected from the city and the citizen. The aim of the design is to encourage people to revitalize the lost connection by spending time in the architecture. In accordance with

Jordens invånarantal ökar med rasande fart vilket också leder till ett ökat behov av mat. Detta har resulterat i ett intensivt jordbruk som bland annat kan orsaka skada på de livsviktiga organismerna som lever i marken. Organismer som lever i marken kan bland annat vara bakterier, svampar och även större organismer såsom daggmaskar. Tillsammans utför dessa viktiga funktioner i marken som är avgöraThis field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. Structural liming is used on clay soils to improve soil stru

Degradation of tools is a prevalent aspect in the mechanical world; due to the advancement of technologies and intense research and development, there are new ways and ideas to curb or delay the tool failures; one such idea is to implement Metal Matrix Composites (MMCs) with various reinforcement materials. This thesis focuses on improving the hardness and wear resistance of Hadfield steel b

Intelligent reflective surfaces (IRS) are envisioned to have a significant number of applications in future wireless network systems by reconfiguring the signal propagation to improve system performance. In particular, the IRS's cell elements can independently reflect the incident signal by tuning its phase and achieving passive beamforming to enhance the received signal of the user equipment.

The Missing Middle describes a phenomenon and a movement to fill a gap in the housing choices offered in many North American cities. Although proponents of the movement state that Missing Middle forms can seamlessly replace single-family housing in existing neighbourhoods, a paradigm shift in Vancouver’s housing supply presents an opportunity to restructure its public spaces and services in tandem

Thesis purpose: The purpose of our research is to examine the intersection of organisational change and the corporate brand identity in the hybrid workplace model. We explore the implications of the model on the corporate brand identity, how brand identity may be shaped in the model and the reasons why identity may change during the hybrid workplace model transformation. Theoretical perspective:

This qualitative mixed methods case study aims to seek understanding of employer branding within the public sector from a New Public Management perspective. The chosen case is two campaigns from the Swedish Armed Forces of 2011 and 2019. Due to political changes in Sweden, the Swedish Armed Forces faced major organizational changes regarding their staffing. Through a text analysis of the commer

The study of the impact of social capital on economic outcomes is currently on the rise. Social capital is a multidimensional concept hard to grasp. This paper makes an attempt to comprise such range of dimensions and analyzes its impact in a potential channel for growth, financial development. Three rural-based provinces of Vietnam are the places where this analysis takes upon. Vietnamese society

Equity crowdfunding has achieved a high popularity in the UK throughout the last years. However, most researchers within this field primarily focused on the success factors of an equity crowdfunding campaign while only little is known about the post-campaign effects. Therefore, the aim of this thesis is to determine which patterns of characteristics successfully equity crowdfunded companies that r

The conflict mineral crisis has been ongoing in the DRC for nearly two decades, with armed groups and increased military presence have played on the tin, tantalum, tungsten and gold to fund a brutal war across the eastern region of the country. Recent international efforts to tackle such illicit trade in conflict minerals has focused on requiring relevant stakeholders involved in the mineral sourc

In 2019, migrant seasonal workers from outside the EU constituted approximately twenty percent of the hired workforce within the agricultural sector in Sweden. However, the total share of migrant seasonal workers is assumed to be even greater. During 2020 this figure dropped significantly due to the travel restrictions associated with the COVID-19 pandemic. According to the Federations of Swedish

This paper examines the reaction of the U.S. stock market to various economic conditions over the last two decades. The major finding reveals a substantial difference between the two subsamples segmented at the decade node. The presence of a moderating effect is highly significant only in subsample 1. The fitting evidence from GJR-GARCH is mixed. In the case of subsample 1, the significance of the

Sustainability transformations will require a fundamental re-thinking of work. However, so far the role of reproductive care work in these transformations is hardly recognized, although this work is low-carbon and essential in sustainable futures. This thesis examines the intersectional coalition politics articulated by feminist activists, climate justice movements and labor unions around the role

The aim of the study was to investigate how municipal home care workers can determine whether an elderly woman in an ordinary home has been or is being subjected to violence, of any kind, by her partner, and how the home care workers respond to their findings. My two key questions were: how do staff detect that an elderly woman is being or has been subjected to some form of violence by her partner
