Adrenaline is a powerful stimulus of glucagon secretion. It acts by activation of β-adrenergic receptors, but the downstream mechanisms have only been partially elucidated. Here, we have examined the effects of adrenaline in mouse and human α-cells by a combination of electrophysiology, imaging of Ca2+ and PKA activity, and hormone release measurements. We found that stimulation of glucagon secret

Learning a language is a creative process. It involves novelty and imagination. While curiosity can be highly beneficial, research is limited. Studies so far conducted have explored epistemic curiosity as a trait-like disposition. In contrast, the current study focuses on perceptual curiosity (PC). PC is a situational response evoked by novelty, complexity and ambiguities in sensory stimulation. P

Background: Glucose-dependent insulinotropic polypeptide (GIP) was the first incretin identified and plays an essential role in the maintenance of glucose tolerance in healthy humans. Until recently GIP had not been developed as a therapeutic and thus has been overshadowed by the other incretin, glucagon-like peptide 1 (GLP-1), which is the basis for several successful drugs to treat diabetes and

The grocery retail industry, with its large product volumes, low margins and fierce competition, is constantly seeking efficiency improvements in its supply chain. The grocery retail industry uses an immense amount of packaging and is directly affected by packaging logistics activities. There is, therefore, a potential for efficiency improvements in the grocery retail supply chain through the inte

I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. Gliding flight performance of a jackdaw was measured in a wind tunnel and I conclude that the current model for predicting optimum wingspan as a function of forward gliding

Previous research showed that living closer to bus stops could be a factor in promoting a healthy and active lifestyle. However, most of the studies relied on self-reported measures of distance, which might be affected by several confounders. In this study, self-reported distances among study participants were compared to actual ones, computed by the use of GIS (Geographic Information System) tech

Purpose: Forensic populations have high prevalence rates of adverse childhood experiences (ACE), but specific pathways from childhood victimization to adult victimizing behavior remain unclear. Difficulties in emotion regulation may prove to be a more proximal risk factor that functions as a pathway between ACE and aggressive antisocial behavior (AAB). In this study, we investigated concurrent ass

Syftet med denna studie var att undersöka ledarstilens samband med organisationens kreativa klimat. Studien avsåg även att undersöka sambandet mellan ledarstil och känsla av sammanhang på arbetet. Data inhämtades via ett pågående forskningsprojekt, vid Institutionen för psykologi vid Lunds Universitet, med syfte att kartlägga organisatoriska förutsättningar för kreativitet och innovation. MaterialThe aim of this thesis was to examine the relationship between leadership style and creative organizational climate. The aim was also to examine the relation between leadership style and work-related sense of coherence. The material for our study has been part of a project at the University of Lund, aimed to study organizational conditions for creativity and innovation. The information was gathere

This study was performed to investigate the psychosocial work environment for priests in Malmö and Lund. The purpose of the study was to identify differences in psychosocial work environment for men and women, and to identify most important areas of problem within the psychosocial work environment. To measure the work environment Copenhagen Psychosocial Questionnaire, COPSOQ, was distributed to 78

Volatility smile arising from the Black-Scholes model is a long studied subject in option pricing theory. By analysing higher order derivatives of the model, I hope to put another perspective to the problem. Accoridng to a study on the American S&P 500 future options, about 90% of the risks of holding an option in five days can be removed by using higher order derivatives of Black-Scholes. The

The debate over Corporate Social Responsibility is present in many parts of society. The business sector’s engagement in CSR has increased rapidly during the last decades. One important question this brings out is how CSR should be governed. The debate consists in large of two views – CSR should be regulated by law or forced regulation or CSR should be managed through private and civil regulation

Denna explorativa studie syftade till att undersöka eventuella samband mellan självkänsla och upplevelse av omvärlden hos individer med psoriasis. Utgångspunkten har varit Maarit Johnsons teori för inre och yttre självkänsla, Aaron Antonovskys teori om känslan av sammanhang samt Gilbert och Miles modell över upplevelse av skam. I undersökningen användes ett egenkonstruerat frågeformulär byggt på sThe purpose of this explorative study was to investigate any connections between self-esteem of individuals with psoriasis and their experience of their social environment. The basis of the study was Maarit Johnson's theory of inner and outer self-esteem, Aaron Antonovsky's theory of the sense of coherence and Gilbert's and Miles' model of shame. In the study a self constructed que
