CSR i sociala medier - Möjligheter och risker med att kommunicera CSR i sociala medier
This B.Sc. Thesis examines how Swedish Large Cap companies communicate CSR in social media. We describe the current state of CSR communication in four different social media channels, Twitter, Youtube, Facebook, and blogs. This research, supported by interviews with stakeholders and a quantitative survey, analyses the potential risks and benefits from communicating CSR via social media and provides concrete advice on the development of a CSR communication strategy for social media. Although some benefits have been realized, many companies have failed to truly reap the potential benefits from an effective social media strategy for CSR.
Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten
In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.
Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider
The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

"Jag vill ju inte vara sämre och landa helt på botten" : En kvalitativ studie om prestationsångest och stress hos gymnasieelever.
Syftet med studien var att undersöka hur familjerättsekreterarna upplever barns situation i samband med deras uppdrag med vårdnads-, boende- och umgängesärenden. Frågeställningarna var; Hur definierar familjerättssekreterarna sitt uppdrag vid vårdnads-, boende- och umgängesärenden vid föräldrars separation? Vilka instrument/verktyg använder familjerättssekreterarna för att ta reda på barns situation i samband med vårdnads-, boende- och umgängesärenden vid föräldrars separation? Hur upplever familjerättssekreterarna att barns fysiska och psykiska hälsa samt relation till föräldrarna påverkas i samband med föräldrarnas separation? Studien utfördes med en kvalitativ forskningsmetod där undersökningen innefattade åtta semistrukturerade intervjuer med familjerättssekreterare. I vår studie har vi utgått från systemteorin och gräsrotsbyråkratin. Detta för att familjerättssekreterarna har myndighetsutövning och att de vid utredningsärenden tittar på hur familjemedlemmarna samspelar med varandra.
Mekaniserad ungskogsbehandling för röjning och skörd :
Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees
of success. Most attempts have been based on techniques where residual stems are straddled.
Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.

Islandshästar med hosta och/eller prestationsnedsättning : skiljer de sig åt jämfört med andra raser?
The purpose of the study was to investigate whether or not Icelandic horses are
less severely affected in clinical symptoms of cough or decreased performance
than other breeds of horses. A breed variation in chronic respiratory disease
severity was suspected based on clinical experience at the Institution for surgery &
medicine, large animal, SLU Uppsala. A retrospective journal study of 17
Icelandic horses and 17 Swedish Standardbred horses with chronic problems with
cough and/or decreased performance compared several measurements of disease
severity.
The clinical signs, physical examination and laboratory testing results compared
were respiratory rate, abdominal breathing, lung auscultation, endoscopy results,
broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All
parameters were available for all 34 individuals except for the blood gases, which
were analysed, in only four Icelandic horses and four Swedish Standardbred
horses.
The only parameters that appeared different between the two groups were
respiratory rate and pO2. The four Icelandic horses, which had blood gases
analysed, had more severe hypoxemia.

Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden
Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.
En kvantitativ studie om lärares inställning till och arbete med Nationella Prov : En enkätstudie i syfte att beskriva lärares uppfattning av huruvida NP bidrar till likvärdig bedömning och ökad måluppfyllelse i mellan ? och högstadiet.
The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.

Mining for culture : performance arts center Ställberg?s Mine
This degree project summarizes five years of education at the landscape architecture program at the Swedish University of Agriculture Sciences, SLU, Alnarp and the School of architecture at Royal Institute of Technology, KTH, Stockholm. The project has been carried out by Lovisa
Berg and Per Crona in collaboration with DRIFT Scenkonst. This master project is based on the ongoing transformation of a former mining site in Ställberg, Bergslagen situated in central Sweden.
The organization DRIFT is in the process of recreating to former industrial mining site as a green cultural center. Their field of artistic examination concerns existential questions connected to the site. The aim is to offer a place for both performing and experiencing contemporary performing arts in Bergslagen.
Our objective is to contribute to the growth of the performing arts project and to demonstrate in concrete terms how a conversion of a mining area can be completed, while taking into account both its history and its new function.
