The use of temporary workers gives companies the opportunity to be flexible, by avoiding hiring and dismissing workers because of economic conditions and trends in demand. The management control in use at the company has the purpose of influencing employees? behaviour to act in the company?s best interest and towards its goals. The management control should also influence the behaviour of the temporary worker. The companies have to create motivation and commitment among the temporary workers although they are employed by a staffing agency.

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

För att förhindra övergödning används skyddszoner i stora delar av Sverige där jordbruk utförs. Det finns även andra faktorer som kan bidra till, eller förhindra, förluster av sediment via fluviala element i landskapet. Variationer i ett vattendrags omland påverkar hur den fluviala transporten av sediment ser ut. Syftet med den här studien är att kartlägga vilka faktorer som kan påverka hur transporten av upplöst sediment ser ut i Librobäckens nedre delar. Hur variationer i omgivningsmiljön skulle kunna skapa variationer i transporten av upplöst sediment.

In the past decade there has been a considerable growth of contingent employment arrangements. In Sweden, the most common among these are the temporary-help service firms. The aim of this study is to investigate how the employees of temporary-help service firms experience their situation as employed by one company and working at another. We have used a qualitative approach to reach an increased understanding for the daily situation of the contingent worker. The essay is based on participant observations and semi-structured interviews with six contingent workers.

Background and problem discussionThe temporary employment industry has grown extensively during the past two decades since the market was deregulated. Companies today need to be flexible to meet fluctuating demand and economic climate in society which has made the market expand. When using employees not directly employed by the company there is a risk that long term effects appears that the companies have not thought of.Aim of studyTo create a model of what negative aspects companies should consider when making the decision to use temporary employees.Methodological frameworkThe study performed through an abdicative literature study and with an empirical data collection method of a qualitative approach where we interviewed five hiring companies and one temporary agency on the decision of hiring temporary employees.Frame of referenceProblem areas with the use of temporary employments were identified through four perspectives of the organization; the structural, human resource, symbolic and political perspective. The problem areas we address are organizational learning, motivation, risk of eroding human capital, belongingness and conflicts. These will be described and presented together with management control to counter the problems.EmpiricsThe empirics are focused on what aspects the companies of the study considered when making the decision to use temporary employment, what the companies? different reasons for using temporary employment are and what they do to minimize possible negative effects.Analysis and conclusionsCompanies use temporary employees mostly to become more flexible, both numerically and in their competence.

This study examines how temporary agency workers experience the working climate in client firms, i.e. how their psychological climate is affected. The study has a qualitative approach based on semi-structured interviews with temporary agency workers. The purpose of the study is to contribute with knowledge about the triangular relationship between the temporary worker, the temporary employment agency and the client firm. Another purpose is to describe how the temporary workers experience the working climate and how this experience is influenced by a number of circumstances. The research question this study aims to answer is How do temporary agency workers experience the working climate in client organisations? And What factors influence this experience? The conclusion of this study shows that the volun- tariness of the psychological contract positively influence the psychological climate, and also whether the temporary workers? expectations correspond to those of the client firm or not.

Geotextildukar används idag som tillfällig kontroll av sedimentgrumling vid vattenarbeten. Syftet med examensarbetet är att ge ökad kunskap kring olika geotextildukars genomsläpplighet med avseende på suspenderat material, PAH (Polycykliska aromatiska kolväten) och kvicksilver vid suspension av sediment från Karlbergskanalen. Detta har gjorts genom en laboration. Resultaten visar att det inom några minuter bildas en filterkaka på de tre undersökta dukarna. Dukarna blir täta då de utsätts för finpartikulärt suspenderat sediment med koncentrationen 57 g/l hämtat från Karlbergskanalen.

The aim of this study is to examine the legal regulation regarding the psychosocial work environment for temporary agency workers. Furthermore, the aim of the study is to examine how temporary agency workers perceive their psychosocial work environment, and possible consequences of such perception. The methodology of the study consists of practical legal method and qualitative method in the form of interviews.The results show that the psychosocial work environment for temporary agency workers is regulated at both the EU legal level by Directive as well as at national level in Arbetsmiljölagen and regulations issued by Arbetsmiljöverket. The study finds that health and safety responsibility for temporary agency workers is shared between the agency and the client company. The result of the study indicates that there are shortcomings in the introduction and training of temporary agency workers, which can contribute to an unsatisfactory work environment.

Temporary architecture is an alternative urban planning concept which has been adapted in many cities worldwide during the last decade. There is however no common definition for temporary architecture and it is diversely labelled and applied. In 2013 it also became publicly introduced in Stockholm via the approval of the city's first architectural guideline. Temporary architecture is presented in the guideline as a potential tool for exploring public spaces among other architecture related themes. The ideas for temporary architecture are ambitious and promising. The problem is that they are vague and leaves questions regarding performance unanswered.

On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.

In the directive 2008/104/EC on Temporary agency work there is a regulation concerning that there shouldn?t be any restrictions or prohibitions in national legislation if it can not be attributed to the public interest. According to that the purpose of this paper is to investigate whether the Swedish law about reemployment in 25 § LAS is a restriction for temporary work agencies, it?s role on the labor market and also to investigate what consequences a restriction can have from a diversity perspective. To fulfill the purpose I have been using a legal dogmatic method based on determination of the current law.I have by the legal research determined that reemployment is not a restriction for temporary work agencies.

AbstractThe use of temporary agency workers has increased significantly during the last decades. Due to considerable differences in the legal status and working conditions of temporary agency workers within the EU, the directive 2008/104/EC on temporary agency work was adopted in 2008. The current directive has a two folded purpose, first and foremost to improve the employment and working conditions for temporary agency workers, by establishing the principle of equal treatment. The second purpose is to create greater acceptance for the temporary work agencies, and also to review and remove any unjustified restrictions or prohibitions against them.There are several different models for labour market regulation represented within the EU. The Swedish and Nordic model has through history relied heavily on regulation via collective agreements, entered into by the social partners, with a minimal amount of state interference and regulation.For Sweden there is a potential problem in the implementation of the directive on temporary agency work, since it follows from case law by the European Court of Justice (ECJ).
