Investing in commodities - Will commodity futures enhance risk-adjusted return in efficient portfolios?

With this paper we intend to investigate what kind of benefits there are by adding commodity futures to a well-diversified portfolio. Since the last fifteen years the commodity speculation has grown tremendously, which partially can be explained by that commodities exposes the investor to certain factors other than an investment in equities. According to our calculations the commodity futures have outperformed stocks during our research period, which partially could be explained by the increasing demand of physical commodities in developing countries e.g. India & China (Akey, 2005). By constructing different portfolios consisting of equities and corporate bonds we could investigate whether our portfolios will benefit from commodity futures and how this will vary over different levels of risk.

Förpackningshantering i det dolda : En studie om hur den interna hanteringen kan synliggöras och förbättras.

Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

Hur påverkar regeringen företagens internationella konkurrensfördelar? : En studie av den svenska miljöteknikbranschen

Sweden experienced a decline in exports of 16 percent in the period after the financial crisis. The decline has created a lot of question marks regarding the traditional exports which has started a process with the aim of finding Sweden?s next cash cow in export.Sweden adopted stringent environmental laws early which positioned them as a strong nation in environmental awareness. The stringent environmental legislation meant that the Swedish companies were required to minimize the environmental impact, which created a demand for eco-efficient products. Despite the early demand for eco-efficient products, the international success of the Swedish cleantech companies has been modest.The government can increase firms international competitiveness by encouraging, supporting and promoting activities on the domestic market.

Effektivitetsparadoxen - En eventstudie av handelsstopp på Stockholmsbörsen mellan 2003 och 2008

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

Effektivisering av logistiklösningar : En jämförelse av nya och gamla logistiksystem vid ROT-projekt

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

Utvecklingen av ett nytt såghandtag

SNA Europe?s handsaw concept is called ?Bahco Handsaw System? and is constituted by a saw handle with the possibility to switch between different saw blades. The sales of ?Bahco Handsaw System? products have not achieved the desired results probably due to the high price. Developing a more cost efficient handle, enabling a lower consumer price of the product, is assumed to increase the sales volume.

Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Effektiva återkopplingsverktyg för elanvändning : En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030

Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased flexibility of electricity use. The primary aim of this study is to identify and analyse how existing feedback tools can be improved, to ensure that they contribute efficiently to the achievement of the EU objectives congruent with a more sustainable energy system in 2030, emphasizing: greenhouse gas reduction, increased energy efficiency and an increased share of renewable energy. In order to reach the primary aim of this study, existing feedback tools have been identified and mapped and interviews with feedback tools providers have been conducted. The study is limited to three research areas: the practical functions of feedback tools, available technology and the use of feedback tools.The use of more efficient feedback tools will provide an increased success rate for energy management, which includes both behavioural changes and energy efficiency. According to the results from the interviews conducted for this study, an increased use and user frequency is important to utilise the energy management potential.

Vaccinering mot galtlukt ? ett alternativ till obedövad kirurgisk kastrering av smågris

In 2012, about 1.3 million boars were surgically castrated, most of them without anaesthesia. Castration is performed to avoid the occurrence of boar taint and aggressive and sexual behaviour. There is a growing concern about the welfare of the piglets and the Swedish Board of Agriculture is working to find efficient and functional alternatives to castration without anaesthesia. The aim of this study was to obtain an overall picture of the latest research about the alternatives to castration without anaesthesia, with focus on vaccination against boar taint, and how they affect the welfare of the pigs. The alternative methods that are available today are surgical castration with anaesthesia and/or analgesia, rearing entire males and vaccination against boar taint.

Energiförbättrande åtgärder på befintliga flerbostadshus : -En lönsamhetsanalys

The EU Council adopted in 2007, environmental and energy goals with the aim of them must be met by 2050. This, in combination with those of the Swedish government 15 enacted environmental goals is supposed to lead the way for the Swedish environmental work.This report has examined measures in properties in the Swedish Cooperative Housing Society (SKB) stocks.The report discusses a range of measures that might be appropriate to apply on the properties to make them more energy efficient.One of the measures discussed, the vent whose primary purpose is to create a good indoor environment for the residents but is also where the most energy is lost.Another measure discussed is insulation of the building envelope on the estate to make it more energy efficient. To put extra insulation on the building envelope is important because of the large amount of energy that is lost through the walls, ceilings and floors.Future actions that may be implemented is individual billing of heating and hot water. This system has been used in European countries since the 70's and today the EU wants to increase the own individuals control over their electricity costs. This has led to a discussion whether to implement the system in Sweden or not.However, there are a number of equitable measures to be sorted out before the system can be used in any great scale.Finally, it is important to remember that environmental measures should be the primary and the pursuit of cost reductions the secondary otherwise you risk the environmental work to be counterproductive..

"Vi både möts och inte möts" - En kvalitativ studie om politikers syn på samverkan med teamchefer inom äldreomsorgen "We both meet and don`t meet" - A gualitative study on politics vision on cooperation with supervisor in old-age care

While conducting our practical training we experienced how the structure and the complexity of the municipal administration could, from a white-collar workers perspective, become a limitation and burden for efficient work. Deriving from this experience we found an interest in how politicians reasoned with regards to their relationship with supervisor in municipal old-age care. Kouzes och Micos (1979) ?Theory of organizational behavior in human service? became our point of departure. Their framework was therefore the foundation for our research and work throughout this paper.Our aim with this research was to examine how politicians viewed their relationship with supervisor in municipal old-age care.

Lane Keeping Aid : ett förarstödjande system för bilar

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Småskalig elproduktion i Arvika

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

Ska man tro på aktie-Nostradamus? : en studie om aktierekommendationers värde för privata investerare

Intro: 80 percent of the Swedish population own shares. This makes Sweden the leading country in private investment in securities. It can be difficult for the private investor to know where, when and which security to invest in. The strategies are as ambivalent as the stock markets fluctuations. If the investor prefers to refrain from investing money himself, there are brokers who carry out these types of services.

Utvecklingen av energieffektiv teknologi i svenska datorcenter

This thesis investigate how energy efficient measures has spread throughout the data centers in Sweden. These questions are put up against a theoretical use of such concepts such as green IT, technological evolution, large technical systems and knowledge dissemination. These theories are used to answer the questions that are encountered during the study, such as how green IT is approached, how big of a role environmental thinking has had in the evolvement of these new technologies. The study has been conducted in a longitudinal manner, it is an observation of the phenomenon that is data centers over a longer period of time. 23 non structured interviews spanning over 27.5 hours of recorded material have been conducted alongside a study of archived material.
