<p>Self-efficacy innefattar tilltro till sin egen förmåga och är ett av de mål som gymnasieskolor arbetar för. En enkätundersökning med hundrafemtio gymnasieelever utfördes med syfte att se hur dessa uppfattar sin egen tro på sin förmåga inom två olika gymnasieprogram utifrån fyra informationskällor. Även fyra intervjuer med lärare genomfördes för att ta reda på hur de arbetar för att öka elevernas tro på sin förmåga. Resultatet utifrån enkätundersökningen visade att eleverna i båda programmen hade hög self-efficacy samt att elever inom naturprogrammet upplevde att tidigare erfarenheter ökar deras self-efficacy. Eleverna inom byggprogrammet upplevde däremot att fysiska och emotionella tillstånd ökar deras self-efficacy. Intervjuundersökningen visade att lärarna genom uppmuntran stöder elevernas self-efficacy. Resultatet stämde till viss del med tidigare forskning.</p>

<p>Människor tenderar att attribuera framgångar till sig själva och misslyckanden till externa källor, fenomenet kallas för Self-serving bias. Hur individer attribuerar kan enligt forskning påverkas av bland annat graden av självkontroll samt självkänsla. Enligt forskning kan intentioner eller beteendemål aktiveras automatiskt och omedvetet av en utlösande signal, så kallad priming, och därmed aktivt guida en persons självreglering. Denna studie har genom ett experiment, med 56 högskolestudenter, undersökt om priming av självkontroll och självförtroende kan påverka hur en individ attribuerar vid framgång och misslyckande. Resultatet visade ingen signifikant skillnad mellan priminggrupperna. Humör visade sig ha betydelse för hur deltagarna attribuerade. En ojämn gruppfördelning och en för bred variationsvidd på beroendemåttet diskuteras om det hade någon påverkan på resultatet.</p>

A model was created in order to assist classical musicians, especially pianists, with the process of creating their own musical niches in order to achieve public recognition, build an audience following and experience financial gain. This blueprint involved creating six arrangements for the piano four-hand medium that were then self-recorded, self-marketed and self-distributed. This essay introduces the repertoire used for this project, five Argentinean tangos by Eduardo Arolas and a habanera by Sebastian Yradier and it also examines the criteria by which they were chosen. A discussion of the arrangements follows, focusing on the compositional techniques that were used. Next, the essay presents the methods employed to self-record, self-market and self-distribute the compilation as well as additional means available to independent musicians pursuing a similar endeavor. The discussion focuses on techniques that pertain to musicians who do not have the support of a record label or a music publisher. The conclusion of this study is that there are a number of accessible methods that independent musicians can employ in order to self-record, self-market and self-distribute their music. However, the level of success of such endeavors depends on the musicians' ability to create a high quality musical product, constantly interact with new audiences and employ various promotional methods. A recommendation for further study is enclosed.

CMOS active pixel sensors (APS) have shown competitive performance with charge-coupled device (CCD) and offer many advantages in cost, system power reduction and on-chip integration of VLSI electronics. Among CMOS image sensors, sensors with logarithmic pixels are particularly applicable for outdoor environment where the light intensity varies over a wide range. They are also randomly accessible in both time and space. A major drawback comes from process variations during fabrication. This gives rise to a considerable fixed pattern noise (FPN) which deteriorates the image quality. In this thesis, a technique that greatly reduces FPN using on-chip calibration is introduced. An image sensor that consists of 64x64 active pixels has been designed, fabricated and tested. Pixel pitch is 18um x 19.2um? and is fabricated in a 0.5-um? CMOS process. The proposed pixel circuit considerably reduces the FPN as predicted in theoretical analysis. The measured FPN value is 2.29% of output voltage swing and column-wise FPN is 1.49% of mean output voltage over each column.

Rationale: The rate of acquisition of drug self-administration may serve as a predictor of later drug-taking behavior, possibly influencing vulnerability to initiate drug use. Objectives: The present study examined the effects of perinatal (gestation/lactation) lead exposure on adult rates of acquisition of intravenous (i.v.) heroin self-administration and cocaine self-administration using an automated procedure that included both Pavlovian and operant components. Methods: For Experiment 1, female rats were gavaged daily with 0 or 16 mg lead for 30 days prior to breeding with nonexposed males. Metal administration continued through pregnancy and lactation and was discontinued at weaning (postnatal day [PND] 21). Animals born to control or lead-exposed dams received indwelling jugular catheters as adults and subsequently were tested daily in a preparation where sessions included an initial 3-hr autoshaping period followed by a 3- hr self-administration period. During autoshaping, heroin (.018 mg/kg) infusions were paired with the extension and retraction of a lever when a lever press was not made for 15 sec, while infusions occurred during self-administration only when a lever press was executed (FR-1). The criterion for acquisition was a 2-day period during which a mean of 10 infusions/session occurred during self-administration. Animals were given 35 days to reach criterion. Results: Findings from Experiment 1 showed the proportion of rats meeting the lever-press response criterion for heroin when tested as adults was lower among lead-exposed animals. In Experiment 2, cocaine (.20 mg/kg) was presented to animals that underwent the same metal-exposure regimen, surgical procedures and methods with variations only in the number of infusions that were automatically administered during the Pavlovian component. Criterion for cocaine acquisition was a mean of 50 infusions over a two-day. In Experiment 2, a greater proportion of leadexposed animals reached the criterion for cocaine acquisition. Conclusions: Developmentally lead-exposed animals showed a decrease in vulnerability to initiate drug-taking behavior when presented with heroin in the adult phase, relative to controls. In contrast, developmentally lead-exposed animals showed an enhanced vulnerability to reach the criterion for cocaine self-administration. Clinical relevance of developmental exposure to lead and the attendant vulnerability to self-administer drugs of abuse is discussed.
