En kvalitativ studie om hur chefer i socialt arbete ser på sitt ledarskap

The aim of this study was; from a group of boys and girls description and interpretation of interaction with other young people, personnel and the environment of the youth centre illuminate how the social gender are constructed and maintained at the youth centre. In this study we have tried to analyse the phenomena from an intersectionalistic perspective. Except gender, the analytic category social class have been tried to capture. Our theoretical standing point is social constructivism. Institutionalized structures in our society are constructed by humans, gender is not only a biological construction it is also a man created construction.

Användning av könssorterad sperma i nötkreatursaveln :

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

Finansiering av företag under rekonstruktion

In this study, company reconstructions and the financing of current accounts hereof are analysed from a perspective of insolvency law. The purpose with a company reconstruction is to maintain the operations of the company despite the insolvency of the mandator. In contrast to bankruptcy proceedings the person liable for payment stays in charge of the operations. However, this person is not allowed to sign for new loans, issue pledges of security for these loans or in any other way enter new obligations without the approval from the temporary company reconstructor. Besides providing for a successful reconstruction the reconstructor also has to consider the interests of creditors, especially to maintain the preferential order of the creditor's claims, keeping them unchanged in case of a formal bankruptcy.

Tågtrafikledare i praktiken : Informationshantering och systemanvändning vid Gävle driftledningscentral

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

En fallstudie av konsult-klientsamspelet vid ERP-implementering. : En fallstudie från den Polska marknaden.

For many providers of ERP-system, Poland is one of the most valuable markets in Central andEastern Europe. The Polish market for ERP-systems is still a growing market, especially; wecan see the low utilization of ERP-systems among small and medium-sized enterprises. Thisis due to several factors, primarily the cost of implementing the system and the necessary infrastructure.Subsequently due to the lack of knowledge, where there is no sufficientknowledge of the benefits arising from the use of an ERP-system in their business, and thereis a fear within the companies that its business would start stagnating.This paper investigates the implementation process of a Polish consulting company whichworks towards small and medium-sized businesses. The key success factors will be studied inthe implementation of ERP-systems, and the instance factors of the interrelationship betweenthe consultant and client from a consultant perspective. The review of the literature has beenidentified and discussed in relevance to the empirical study.

Ledarskap i en agil verksamhet : En kvalitativ studie om hur ledarskapet påverkas vid en förändring

Syftet med denna undersökning har varit att utforska och förstå hur ledarskapet påverkas när en organisation genomgår en förändring till en agil verksamhet. Bakgrunden till undersökningen grundar sig i den traditionella synen på ledarskap där chefen ledde och fördelade arbetet. Under 1950-talet förändrades synen på arbetsledning och arbetsfördelning där medarbetarna blev allt mer delaktiga i arbetsprocessen.Med utgångspunkt i detta har vår forskning behandlat de effekter på ledarskapet som inträffar när en organisation går ifrån ?command and control? till ?empowerment?. Därav har vi ställt upp följande frågeställningar; Hur har kontrollen (över teamen) förändrats för linjechefen i övergången från Classic Waterfall till Agile, På vilket sätt har förändringen påverkat linjechefens informationshämtning till att genomföra IPM-samtal och Vilka effekter får förändringen på ledarstilen när organisationen övergår till en agil organisation.Vi har använt oss av en kvalitativ metod där åtta semistrukturerade intervjuer genomfördes med linjechefer ur två avdelningar för att samla in vårt empiriska material.

Design av PID-regulator baserad på kommersiell processormodul

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

There are an increasing number of people suffering from depression and depressed mood. Concurrently important benefits have been noticed from the effects of massage, effects that can be assumed to restore individual?s health with depression and depressed mood. The aim of the study was to examine the importance of gentle massage in connection with depression and depressed mood. The research was based on scientific studies that were applied through the databases Cinahl, elin@Kristianstad, PsycARTICLES, PsycINFO, PubMed and the journal Vård i Norden as well as by manual searches.

Investigation of tissue factor mRNA levels in human platelets using real-time PCR

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer

In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.
