I detta examensarbete utförs en jämförande analys av metoder och verktyg för hantering och analys av data inom datalager. Med den snabbt ökande mängden data och utvecklingen av molnteknologier står företag inför utmaningen att navigera bland olika metoder för att välja den mest lämpliga för sin specifika datahantering och analysbehov. Rapporten belyser metoden One Big Table (OBT) samt verktyget Data Build Tool (dbt) och undersöker deras för- och nackdelar i datalagermiljöer. För att få en djupare förståelse för deras funktion och effektivitet jämförs de i olika användarfall genom prestandatester på latens och samtidighet med hjälp av verktyget Hyperfine. OBT implementeras med hjälp av Google BigQuery såväl som Google Cloud SQL för PostgreSQL där latens och samtidighet för analytiska målsättningar utvärderas genom användning av Python-skript med SQL-frågor respektive med dbt-modeller. Skripten och dbt-modellerna körs mot BigQuery samt PostgreSQL och de båda implementerar OBT. Resultatet visar att SQL-skripten uppvisade lägre latens än dbt-modeller när de exekverades mot både BigQuery och PostgreSQL. Ett annat fynd är att latensen för SQL-skripten var lägre i PostgreSQL jämfört med BigQuery, medan dbt-modellerna istället uppvisade högre latens i PostgreSQL jämfört med BigQuery. I båda datalagermiljöer visas det även att SQL-skripten presterar bättre än dbt-modeller vid samtidiga körningar. / This bachelor’s thesis presents a comparative analysis of methods and tools for data management and analysis within data warehouses. With the rapidly increasing volume of data and the development of cloud technologies, companies face the challenge of navigating various methods to choose the most suitable one for their specific data management and analysis needs. The report highlights the One Big Table (OBT) method and the Data Build Tool (dbt), examining their advantages and disadvantages in data warehouse environments. To gain a deeper understanding of their functionality and efficiency, they are compared in different use cases through performance tests on latency and concurrency using the Hyperfine tool. OBT is implemented using Google BigQuery as well as Google Cloud SQL for PostgreSQL, where latency and concurrency for analytical purposes are evaluated using Python scripts with SQL queries and dbt models. The scripts and dbt models are run against BigQuery and PostgreSQL, both implementing OBT. The results show that the SQL scripts exhibited lower latency than the dbt models when executed against both BigQuery and PostgreSQL. Another finding is that the latency for SQL scripts was lower when run against PostgreSQL compared to BigQuery, while dbt models showed higher latency when run against PostgreSQL compared to BigQuery. The SQL scripts also performed better than the dbt models in concurrent executions in both BigQuery and PostgreSQL.

Dialektisk Beteendeterapi (DBT) är en beforskad behandling avsedd för personer med borderline personlighetsstörning. Medveten närvaro (mindfulness) ingår som en del i DBT. Det är oklart hur de olika delarna i behandlingen påverkar helhetseffekten av DBT. Syftet med denna studie var att se i vilken utsträckning patienter som avslutat DBT-behandling för minst 6 månader sedan använder sig av medveten närvaro och om detta användande har samband med ökat välbefinnande och minskade borderlinesymtom. Korrelationer och multipel regressionsanalys användes för att undersöka dessa samband. Hänsyn togs till relevanta bakgrundsvariabler. Resultatet bekräftade samband mellan mindfulnessanvändande och större välbefinnande, respektive mindre självskadebeteende och mindre identitetsproblem. Studien är en korrelationsstudie och inga kausala slutsatser kan dras.

The relationship between religion and mental healthcare are somewhat complicated with the psychiatric need for control and religions attempt to accept what we cannot control. Swedish mental healthcare is undergoing a change towards a more individualistic and patient ruled care. Throughout the world clinicians are more and more convinced with the positive effects religion and spirituality can have on the recovery process for the mentally ill. This paper will show a variety of different studies made on the effect of combining religious coping with mental illness as well as showing result from interview made especially for the context of this paper. The result of these combined studies shows an overall positive effect of religious coping for the mentally ill. Focus within the primary study is behaviourproblematics with extra attention on IPS, emotionally instable personalitydisorder formerly known as borderline personalitydisorder and posttraumatic stresssymptom.

In state psychiatric hospitals in the United States, many patients are admitted with a history of trauma. Although trauma-focused interventions are offered within these psychiatric facilities, there remain issues with the higher-than-average length of treatment and rehospitalization rates for patients with a diagnosis of posttraumatic stress disorder or for those who are suffering with a history of trauma. This study investigated between group differences for measured levels of attendance and type of group intervention (which included the men's trauma recovery empowerment model, dialectical behavior therapy, and art and healing) on the risk for violence as measured by scores on the historical, clinical, and risk-20 (HCR-20 v2) checklist. Participants had documented trauma history as well as mental health disorders including schizophrenia, schizoaffective, bipolar disorder, major depressive disorder, posttraumatic stress disorder, and substance abuse. Cognitive behavioral and social learning theory comprised the theoretical foundations for the study. Archival data from the past 6 years included 16 participants from the M-TREM group, 15 participants from the DBT group, and 15 participants from the Art and healing group. Data were used to complete a nonequivalent control group design and data analysis included an ANOVA, correlation, and regression analysis. The results of this study identified a statistically significant difference in risk for violence based on level of attendance but not by type of group intervention. The findings of this study will assist psychiatric hospital administrators and mental health professionals in the development and implementation of effective trauma programming to lower the risk for violence for patients with trauma.

Bulk metallic glasses (BMGs) are a new class of structural materials and exhibit unique combinations of mechanical properties. As a result, their mechanical behavior has been an active area of scientific pursuit in the recent past and considerable emphasis has been paid to understand plastic deformation in them. It is now well accepted that shear transformation zones (STZs), aided by free volume, are the fundamental carriers of plasticity. At a microscopic level, deformation at low temperatures and high stresses tends to localize into shear bands. Most BMGs posses high fracture toughness despite high yield strengths and poor global ductility. However, the micro-mechanisms of fracture and fatigue in this new class of materials are not fully understood yet. The overall objective of this study is to provide insights into the fracture and fatigue response of amorphous alloys, which is important both from scientific and technological perspectives. The key questions we seek to answer through this study are the following. Do amorphous alloys undergo a ductile-brittle transition (DBT), and if so what are the reasons for it? What are the parameters that influence fatigue crack initiation in amorphous alloys and whether fatigue life can be improved by surface treatments? A related question is whether the BMGs are susceptible to deformation-induced crystallization (DIC). A Zr-based BMG, Zr41.2Ti13.75Cu12.5Ni10Be22.5 was utilized to conduct this study. By comparing the fracture and fatigue behaviors in the as-cast and annealed states {annealing was carried out below the glass transition temperature (Tg) because of established embrittlement effects}, we seek to provide answers for the questions posed above. We begin by examining the influence of temperature on the toughness of BMGs. Impact toughness measurements show that the annealed samples, which are brittle at room temperature, recover the lost toughness beyond a critical temperature (TDB) and exhibit a sharp DBT. However, the hardness remains unaffected across the TDB. Fractography reveals nano-scale patterning and cleavage fracture in the brittle state, while the formation of thick vein-patterns and shear fracture are characteristics of the ductile state of the annealed samples. We explore various micro-mechanistic possibilities for explaining the features of this transition, including a critical Poisson’s ratio-toughness correlation. Next, to understand the origins of fatigue crack initiation, we study the un-notched fatigue response of as-cast and sub-Tg annealed Zr-based BMG specimens. Because of embrittlement and nano-crystallization at the crack initiation region, the annealed specimens exhibit a lower fatigue life than the as-cast specimens. Shot-peening of the as-cast specimens did not exhibit significant improvement in their fatigue performance because of competing effects between the compressive residual stress field (CRSF) and deformation-induced softening. To further investigate surface and repeated loading effects, the tribological response of the as-cast Zr-based BMG was compared with specimens annealed above and below the Tg. A good correlation between the hardness (increasing as a function of the annealing temperature) and wear rate was obtained. The formation and peeling of the oxide layer formed during testing was the primary wear mechanism in all the specimens. Lastly, crystallization was observed within the deformed region of the as-cast Zr-based BMG repeatedly scratched with a sharp diamond indenter. But, transmission electron microscopy (TEM) does not reveal any evidence of crystallization within the indents formed within an electron transparent film formed by laser deposition of the as-cast Zr-based BMG. Absence of crystallization in deformed regions obtained by designing critical experiments, which avoid artifacts generated during sample preparation, suggests that the occasional observation of DIC might be an exception rather than the rule in BMGs.

The fields of psychology and rhetoric share the goal of improving human mental health and behavior through persuasion. This thesis traces the history of rhetoric and psychology theory, focusing on the parallel theories of Nienkamp's internal rhetoric and Herman's dialogical self. Both theories model the human mind as having multiple psyches that actively interact to interpret human experience and project human behavior. I conclude with a case study of anorexic patients using ethos, pathos, and logos in dialectical behavior therapy (DBT), arguing that principles of rhetoric can help patients with mental disorders cognitively realign their thinking more effectively than drug treatments can.
