The unattended collection and delivery point (UCDP) is one of several solutions to address the delivery issues arisen by increasing online retail sales. There are four solutions of the UCDP concept: the traditional parcel locker, the automated box design, the automated pillar design and the cart design. Moreover, the physical dimensioning of a UCDP mainly needs to consider the number of orders, or

In empirical economics, the generalized method of moments (GMM) is one of the most widely used methods for estimating models with fixed effects, such as the dynamic panel model. For the dynamic panel model, the two most widely used GMM-based estimators are the so-called difference GMM and system GMM estimators. However, it is typically the case that such estimators are asymptotically biased of order

In recent memory the question of climate change has been at the forefront of a great deal of debates at the international level and with the Paris Agreement and the continuation of COP-meetings in the future, the preoccupation with climate change is sure to continue and to involve many different actors. The question of how a state such as Denmark, traditionally known as a state dedicated to fighti

In recent years, insufficient obstetric care has been a highly debated topic in Swedish media and politics. However, despite reports on e.g. the country’s high prevalence of birthing injuries, the recent closing of numerous maternity wards and a severe lack of midwives, the development of Sweden’s medical birth outcomes has been stable. Thus, based on the assumptions that (I) said quality measurem

Communities of Practice (CoPs) have been featured heavily in the literature of organisational learning and knowledge sharing in recent years. However, the concept denotes a paradigmshifting learning theory that goes beyond a mere management tool. In the present text, we review the CoP literature and argue that it lacks an elaborate explanation of CoPs’ organisation, resorting to saying they are ‘s

Following the UNHCR:s launch of the #IBelong Campaign to End Statelessness by 2024 in November 2014, a Global Action Plan to End Statelessness: 2014 – 2024 was adopted urging states to undertake ten actions to end statelessness, including to facilitate the naturalization of stateless migrants. While the facilitated naturalization of stateless persons would certainly reduce the occurrence of statel

Semantic Web technology has attracted much interest for its ability to integrate and deliver information from different sources, and increasingly, geodata are being published as triple data according to the graph structure laid out in the Resource Description Framework (RDF). Although the Semantic Web already contains a large volume of geotagged information, there is still a lack of suitable geome

The world as we know it today has evolved to be a very connected space, where not only ICT’s (information & communication technologies) have made it easy to interact with individuals around the globe at any time, but also developments in air travel allow to reach ever more distant destinations. Many go as far as describing the world as shrinking or small; it seems that at least it feels smalle

In recent decades, industrialized economies have significantly increased their R&D efforts while economic growth rates have been relatively stable. This goes against the conclusions of most previous economic models of endogenous growth. In this paper, an endogenous growth model has been created in which technology is treated as an income-compensated factor of production. The purpose is to crea

Denna uppsats undersöker hur den svenska barnrättsorganisationen Bris skapar förtroende och visar försiktighet i sina livechattar, som riktar sig direkt till barn och unga under 18 år. Syftet är att undersöka vilka språkliga strategier som kuratorer på Bris använder i sina svar till barnen för att skapa kontakt och närhet, men samtidigt visa respekt och hålla distans. I undersökningen utgår jag fr

The emerging market for meat substitutes has largely been filled with different types of soy products. Although soy usually has a lower environmental impact than meat, soy is not entirely unproblematic. Deforestation and global transportations are two negative effects of the increasing production of soybeans. One of these meat substitutes is tempeh: an Indonesian mold-fermented food usually made o

With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations,dynamic charge through Electric Road Systems (ERS) is in development, and fast charging stations are being deployed all over the world. This thesis focuses on combining the use of both technologies, attempting to use an EL

Det har länge funnits ett fokus på att uppnå en säker och trivsam arbetsmiljö. Den fysiska arbetsmiljön har i över 100 år haft arbetslagstiftning och tillsyn för att skydda de anställda på svenska företag. Det var först år 2001 som regeringen gjorde en sammanslagning av Arbetarskyddsstyrelsen och Yrkesinspektionen som skapade Arbetsmiljöverket. Samma år beslutades det om en stor satsning på den ps

En diofantisk ekvation är en polynomekvation i två eller flera variabler, där polynomet har heltalskoefficienter och man söker heltalslösningar. Det enklaste (och kanske mest praktiskt användbara) fallet är det linjära, ax+by=c. I sådant fall är det enkelt att hitta lösningar (x,y), eller visa att inga lösningar existerar, med hjälp av Euklides algoritm eller kedjebråk. För diofantiska ekvationer This thesis deals with some special types of Diophantine equations. Two classic cases of Fermat's equation are shown to have no nontrivial integer solutions, using two different approaches. The rest of the thesis deals with some instances of y^2=x^3+k, commonly known as Mordell's equation. In most cases, no integer solutions exist.

In this paper we investigate whether a modern approach to identifying the desirable locations to launder money, the Walker Attractiveness Index, is suitable, and compare its projected results with those revealed by the Panama Papers leak. We find that the model does a poor job at predicting the real-world results, and propose that it be revised. To this we provide some policy recommendations that

Urbanization is a process where rural population move to urban places for better job opportunities and facilities. This is a natural process and more or less unavoidable. But when this process takes place rapidly and at large -scale, the urban cities will undergo various changes that will impact the environment. Rapid and large-scale urbanization is mainly observed in developing countries of Asia

In 2013 Kenya implemented their devolution, which is the process of devolving political functions, fiscal resources and administrative responsibilities to sub-national units. The central reason behind this constitutional change was to address the chronic ethnic conflicts of Kenya. A part of the ethnic conflict in Kenya is the plague of corruption, where it has divided the people of Kenya, putting

The purpose of this study has been to look at four peoples life stories about their experiences of drug use over time as well as to share their individual attitudes, and possible experiences, of drug-related support and treatment. The life stories of these four people were collected through semi structured interviews, after which they were analyzed based on narrative aspects conveyed in their stor

In this thesis we test the performance of hedge funds against several fund specific variables, mainly fund size. As a measure of the hedge funds performance we employ both excess and risk-adjusted returns. The first part the thesis employs unbalanced panel regressions where hedge funds excess returns are run on several fund specific variables. In the second part several financial performance measu
