ABSTRACT Standardized assessment instruments have increasingly come to be used in social work. Although national studies of ASI and DOK's reliability and validity has only been examined to a limited extent. In order to improve knowledge of assessment instruments conditions, relevance and scope, this present literature study highlights the background and the application of the interview methods ASI and DOK, used in swedish abuse and dependent care. In answering the survey questions, a qualitative content analytical method has been used. ASI and DOK are multidimensional interviews which take into account that several areas affecting the client's treatment outcome. Assessment instruments differ in respect of use, approach to the assessment of client needs and help troubled, the basis for the interview estimates and its rating scales. International research shows that the ASI and DOK include a number of methodological problems that affect the reliability and validity in self-reported data. Assessment instruments different question areas, however, lacks a theoretical framework that allows any assumptions about the causal relationships between key areas of life and substance abuse problems. In accordance with a social constructionism perspective, ASI and DOK's usability are time and culture bound and must therefore be seen as methods that are in a constant process of change to generate as reliable knowledge as possible. Keywords: assessment instrument, social work, Addiction Severity Index, ASI, documentation system, DOC, structured interviews, addiction, substance abuse.

Magister Educationis - MEd / In Suid-Afrikaanse skole word op 'n gereelde grondslag gevind dat nie alle leerlinge baat vind by gewone groeponderrig soos dit in die gewone klaskamer vergestalting vind nie. Enersyds is daar die groep wat op Buitengewone Onderwys aangewese is, en andersyds is daar die groep wat nie vir buitengewone onderwys kwalifiseer nie, maar nog steeds nie die mas in die gewone klas kan opkom nie. Laasgenoemde maak dikwels deel uit van 'n sosio-ekonomies of polities benadeelde groep en die grootste persentasie druipelinge en vroeë skoolverlaters, in vergelyking met die res van die skoolbevolking , kom uit die groep. Die swak akademiese prestasies van hierdie leerlinge word in die meeste literatuur gekoppel aan kognitiewe benadeeldheid. Opvoedkundige Sielkunde. Kognitiewe benadeeldheid word vir die doel van hierdie mini-tesis gelykgestel aan kulturele benadeeldheid, maar dit word gekoppel aan die definisie van Feuerstein wat dit beskou as 'n gebrek aan bemiddelde leerervaring (BLE). Te midde van 'n strewe na sosio-ekonomiese, politieke en opvoedkundige rekonstruksie in Suid-Afrika, is dit belangrik dat probleme met skolastiese prestasie op die intermediêre vlak aangespreek word. Alhoewel skole weinig kan doen om 'n radikale verandering in die omgewingstoestande van leerlinge teweeg te bring, kan dit egter 'n groot bydrae lewer in die ontwikkeling van die kognitiewe vermoëns van kinders. Om hierdie belangrike funksie te vervul, is ditnoodsaaklik dat onderwysers in hul voorbereiding vir hul taak deeglik toegerus moet word met gepaste teoretiese begronding, asook daaruitvloeiende maatreëls om kognitiewe benadeeldheid by hul leerlinge effektief te verklaar en te bekamp. Die fokus in hierdie mini-tesis is op die benadering ten opsigte van kognitiewe benadeeldheid by primêre skool leerlinge in die opleidingsprogramme - spesifiek die Opvoedkundesillabusse - van onderwyskolleges van die Departement van Onderwys en Kultuur, Raad van Verteenwoordigers (DOK:RV); en die Departement van Onderwys en Opleiding (DOO), asook ontwikkelinge op die gebied van kognitiewe onderwys in Suid-Afrika. Op grond van die leemtes in die betrokke opleidingsprogramme is die doel van hierdie mini-tesis om BLE as noodsaaklike komponent in die opleidingsprogram van primêre skoolonderwysers in Suid- Afrika aan te beveel.

Pesquisas apontam vocabulários como uma fonte valorosa de informação sobre o projeto. Para entender a natureza e o potencial dos vocabulários, desenvolvemos um ferramental capaz de extraí-los a partir de código fonte. Explorando os dados estatisticamente, identificamos duas propriedades de vocabulários: tamanho, expresso como função de potência de LOC (Lines-Of-Code); e a repetição de seus termos, que se ajusta a uma distribuição log-normal. Vocabulários, bem como suas propriedades e operações foram formalizadas baseadas no conceito de multisets. O ferramental de extração e a formalização viabilizaram cooperações científicas sobre a utilidade de vocabulário sem atividades de manutenção. Esse conhecimento acumulado revelou que vocabulário pouco foi explorado como insumo à modelagem de conhecimento de código. Desenvolvemos então uma abordagem para identificar especialistas de código cujo conhecimento é definido pela similaridade existente entre vocabulários das entidades e dos desenvolvedores. Comparamos a precisão e cobertura da nossa abordagem com de duas outras: baseada em commits e baseada em percentual de LOC modificadas. Os resultados apontam que para indicar um único especialista, top-1, a nossa abordagem tem uma precisão menor, entre 29.9% e 10% que as abordagens de baseline. Já para indicar mais de um desenvolvedor especialista, até top-3, a nossa abordagem tem uma acurácia melhor de até 18.7% em relação as de baseline. Identificamos também que o conhecimento definido por similaridade quando combinado com um modelo baseado em autoria aumenta a capacidade de identificar especialistas, no R2 do modelo, em mais de 4 pontos percentuais. Concluímos que além de poder ser utilizado de forma isolada para modelar conhecimento de código e assim identificar especialistas, o vocabulário pode ser um componente adicional a modelos de conhecimento baseados em autoria e propriedade, já que capturam aspectos diferentes dos existentes nesse modelos. / Identifiers and comments from a source code are the software vocabulary. Research point vocabularies as a valuable source of information about the project. To understand we developed a tool that extract them from source code. Exploring the data statistically, we identify two vocabularies properties: vocabulary size, that is a power function of LOC (Lines-Of-Code) and the repetition of vocabulary terms that fits alog-normal distribution. Vocabulary as well as their properties and operations were formalized based on the concept of multisets. Extraction tool and formalization made possible scientific cooperation on usage of vocabulary in maintenance activities. This accumulated knowledge has shown that vocabulary was not explored as an input to code knowledge. Then we developed a code experts identification approach whose knowledge is defined by existing similarity between entities and developers vocabularies. We compared precision and recall with two baseline approaches: based on commits and based on percentage of modified LOC.The results show that to indicate a single specialist, top-1, our approach has alower precision, between 29.9% and 10%,than baseline approaches. More than one specialist-developer, up to top-3, our approach has better accuracy of up to 18.7% over those of the baselines. We also identify that the knowledge defined by similarity when combined with an authorship model enhances the ability to identify experts, R2 of the model, by more than 4 points. We conclude that vocabulary can be solely used to expertise, and thus identify experts. In addition, vocabulary can be an additional component for models based on authorship and ownership, since it captures different aspects from ones existing in these models.

The aim of this thesis is to undertake simplified design and assessment of cofferdam under vertical surcharge in the form of virtual project. Cofferdam constructed on the sea shore must be able to withstand all loads to enable construction of cut and cover tunnel. As a part of the design it is required to assess ground conditions and it is necessary to review feasibility of the structure on the sea. The construction will be described in construction phases and graphically demonstrated in construction sequence drawing. Because the structure is designed for life time of five years, temperature load on struts is studied in the thesis and further considered in structural analysis. Furthermore, it is required to compare analytical models from GEO5 and PLAXIS. Horizontal frame is analysed separately in Scia Engineer. Structural members – cofferdam wall, waler beam and strut are checked in this thesis. For the design of the cofferdam wall second order theory is considered. All mentioned requirements were accomplished with help of corresponding Eurocodes, books and technical advice. Results of this work are feasible and it was possible to design all members to enable construction of the cut and cover tunnel. The phasing was designed such that deformation of the cofferdam is minimalized and use of machinery is limited to machines on temporary platforms. Comparison of two different analytical models showed that different soil modelling has great effect on internal forces, even though the shape of the bending curve is very similar, values obtained from PLAXIS software are much higher. Assessment of the structural members is done according to Eurocode 3, and horizontal frame is checked also against disproportionate collapse.

Bakgrund: Till operationssjuksköterskors ansvarsområden hör hygien och infektionsprevention. Vårdrelaterade infektioner (VRI) drabbar drygt 55 000 patienter i Sverige varje år. Av dessa VRI är runt 12 000 postoperativa sårinfektioner (SSI), varav hälften beräknas vara möjliga att undvika. En vanlig orsak till SSI är att bakteriebärande partiklar i luften, colony forming units (CFU), hamnar i operationssåret. Antalet personer i salen, personalens klädsel och antalet dörröppningar är några faktorer som antas påverka CFU-halten i operationssalens luft. Det råder osäkerhet kring vilka infektions-förebyggande åtgärder som bör prioriteras för att hålla CFU-halten nere och säkerställa en säker vård. Syfte: Att undersöka sambandet mellan CFU-halten i operationssalens sterila område och miljöfaktorer i salen.  Metod: En prospektiv icke-experimentell korrelationsstudie med kvantitativ ansats genomfördes. CFU-halten mättes med en aktiv luftprovtagare under 113 mätperioder fördelade på 17 operationer i en operationssal utrustad med LAF-ventilation. Samtidigt observerades antalet personer, antalet personer utan dok och antalet dörröppningar. Med hjälp av SPSS beräknades korrelationerna mellan de studerade variablerna. Resultat: Inget signifikant samband kunde påvisas mellan CFU-halten i operationsområdet och antalet personer i salen, antalet personer utan dok eller antalet dörröppningar. Slutsats: Luften i operationsområdet höll genomgående en ultraren nivå och CFU-halten påverkades inte av de studerade miljöfaktorerna. Detta är positivt ur perspektivet säker vård då det tyder på att risken för att drabbas av en postoperativ sårinfektion på grund av bakterier i luften är liten i salar med LAF-ventilation. Därigenom undviks onödigt lidande för patienter och kostnaderna för samhället hålls nere. Risken att drabbas av SSI påverkas av fler faktorer. Mer forskning behövs innan nuvarande rutiner kan ändras. / Background: Hygiene and infection prevention are two of the responsibilities of the operating room nurse. In Sweden, roughly 12,000 patients suffer from surgical site infections (SSI) each year, many of which could be avoided. A common cause of SSI is bacteria-laden particles (CFU) in the air of the operating room. The number of people in the room, the attire of the surgical staff and the number of door openings are thought to affect the CFU count. It remains unclear what preventive measures are most effective in reducing the CFU count to provide the safest care possible. Aim: To investigate the relationship between the CFU count in the sterile area of the operating room and various environmental factors. Method: A prospective, non-experimental correlational study was conducted. The CFU count was measured through active air sampling during 113 ten-minute periods, distributed over 17 operations, in an operating room equipped with a laminar air flow ventilation system. Simultaneously, observations were made of the number of people in the room, the number of people wearing a specific type of surgical cap called “dok” and the number of door openings. Correlations between variables were calculated using SPSS software. Results: No correlations between the CFU count within the sterile area and the studied variables were found. Conclusion: The air in the sterile area remained ultra-clean throughout the study, and the CFU count was not affected by the studied variables. This indicates that the risk of suffering from SSI caused by airborne bacteria is low, which benefits both patients and society. However, there is still a significant risk of suffering from SSI because of other risk factors. More research is needed before any new recommendations regarding hygiene routines in the operating room can be given.
