Denna uppsats undersöker effekterna av första generationens biobränslen, såsom bioetanol och biodiesel, på jordbruksprodukters prisnivåer både inom länder och internationellt ? samt dessa prisers vidare påverkan på svält i utvecklingsländer. En enkel sektormodell för utbud och efterfrågan, uppdelad i tre delmarknader, utnyttjas först för att illustrera och förklara biobränslens grundläggande kvalitativa priseffekter på jordbruksmarknader. Andra forskningsstudiers och modellers kvantitativa uppskattningar av samma skeenden granskas och vidareutvecklas. Den relativa andel hos senare tids prisstegringar (den så kallade ?matkrisen?), vilken kan tillskrivas biobränslens effekter, skattas med försiktighet: min uppskattning blir att i storleksordningen 10 procent av de samtida prisökningarna beror på biobränslen, med viss variation för enskilda produkter.

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Because of the increasing numbers of international tourist arrivals each year it is essential that tourist operators are aware of the impacts that tourism generate. Tourism affects the world in an environmental, social and economic way, positive but also in a negative way. To travel responsible and sustainable is therefore important, and operators have a responsibility in this subject.Because of this I wanted to look at how Swedish tourist operators manage responsible tourism, together with what amount of information their customers receive about this. To be able to study how operators work with this I conducted three interviews via email. The tourist operators were of different sizes and specializations to receive a more extensive result.

Utländska direktinvesteringar har ökat markant de senaste 10 åren, en utveckling som påverkar det dagliga livet för allt fler människor då företagens investeringar ger upphov till såväl nya blomstrande orter som nya ödebygder. Denna uppsats syftar till att på företagsnivå undersöka vad som påverkar val av geografisk plats för direktinvesteringar utomlands. I undersökningen har de faktorer som lyfts fram av den nya handelsteorin samt ekonomisk geografi undersökts. Dessa faktorer är tullar och andra handelshinder, transportkostnader, agglomerationseffekter, närhet till och storlek på marknader, positiva externaliteter samt skalfördelar. Hur viktiga dessa anledningar är har i denna uppsats undersökts genom en kvalitativ enkätmetod, där företagen själva har svarat på i vilken grad varje enskild anledning påverkat investeringsbeslutet.

Nowadays the world of football has become more commercial than before. As a result of this the clubs' financial status is getting more and more important. Therefore the UEFA has given the national federations a specific task to make sure that the clubs from each country follow certain standards of maintaining the football credibility. The Swedish federation has decided that the Swedish clubs must follow the so-called ?elitlicensen?.

The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.

Denna uppsats behandlar utkontrakteringar i offentlig sektor och som praktikfall har utkontrakteringen av äldreboendena Nibblegården och Ärtan i Lunds kommun valts. Själva syftet med uppsatsen är att få en uppfattning om vilka effekter som uppkommer vid utkontrakteringar. I uppsatsen diskuteras även vad som bör beaktas vid utkontrakteringsbeslut (eller återtagande av utkontrakterad verksamhet). Den innehåller också en analys av hur kontrakt mellan det offentliga och privata aktörer är utformade och hur utformningen stämmer överens med den ekonomiska litteraturen. Studien har visat på att det finns vissa skillnader finns mellan teori och empiri vad gäller kontrakts utformning.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

Public health focuses on interventions related to physical activity during leisure and at work under conditions where health care is offered during working hours. Increased physical activity offers many positive effects on health in general and reduces the risk for most injuries and illnesses. Female cleaners represent a profession that is largely composed of women at high risk of overload injury and rarely participate in wellness initiatives offered at workplace. The purpose of this study was to investigate the effects of 20 minutes of daily physical exercise for 10 weeks of intervention for healthy female cleaners. A total of 40 female cleaners in a larger organization participated in the study and were divided in into an intervention group and a control group.

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

Kvinnors och mäns relativa vilkor på arbetsmarknaden är intimt sammanknippade med fördelningen av betalt och obetalt arbete inom hushållet. Denna fördelning kan påverkas genom ekonomiska incitament och familjepolitiken har en viktig roll i detta sammanhang. Sverige står nu inför en familjepolitisk reform, bestående av ett vårdnadsbidrag, en jämställdhetsbonus och ett skatteavdrag för hushållsnära tjänster. Denna uppsats diskuterar dessa reformers förväntade effekter på tidsallokeringen inom hushållet och hur dessa effekter kan förväntas skilja sig mellan olika socioekonomiska grupper. Den teoretiska ramen utgörs av Gronaus tidsallokeringsmodell och en hushållsmodell utformad av Blau et al.
