Behavioral Impact of Short-Term Stock Price Trends on Equity Research : A Textual Analysis of Trend-Chasing Bias in Norwegian Equity Research Reports Covering the Oslo Stock Exchange

This thesis employs XGBoost and linear regression to reveal whether short-term stock price trends can explain the variance in textual sentiment in Norwegian equity research reports covering the Oslo Stock Exchange, investigating whether trend-chasing bias is present in equity research. The thesis is based on 2,350 equity research reports from the past 5 years covering the 25 largest companies by market capitalization listed on the Oslo Stock Exchange, published by Carnegie, DNB Markets, and Pareto Securities. We present empirical evidence demonstrating an enhancement in the predictive efficacy of our model with the integration of short-term stock price trend indicators. Specifically, the incorporation of these indicators resulted in a 2.2% increase in the linear regression model’s explanatory power compared to our reference model. The full model can account for 44.7% of the variance in textual sentiment. Further, the XGBoost model improves predictive accuracy over the linear model and returns the lagged sentiment, investment bank, financial leverage, and RSI to be the most important variables explaining sentiment, chronologically ordered by variable importance. The 3-month simple return and MACD prove to be similar in variable importance with traditional valuation metrics such as the P/E ratio and firm size. Thus, we find that stock price trend indicators improve the models capacity to explain the sentiment of an equity research report. However, our findings cannot state that the given dependency is due to trend-chasing bias in Norwegian equity research. The textual sentiment is determined by numerous unobservable variables, making it likely that our model suffers from omitted variable bias, thus causing endogeneity issues. Further, we cannot determine if a change in textual sentiment is attributable to a measurable change in the perception of a company, or the fact that the reports summarize and relay market information.nhhma

Förderpotenziale von erfahrungsgeleiteten Begegnungen zwischen Kind und Tier

Tiere haben eine besondere Wirkung auf Kinder. Dies steht heutzutage vor allem bei der Gesundheitsförderung während der kindlichen Entwicklung im Fokus. Das Ziel in der vorliegenden Arbeit ist es zu beantworten, welche Förderpotenziale durch erfahrungsgeleitete Begegnung zwischen Kind und Tier entstehen. Dazu wird die folgende Forschungsfrage gestellt: Welche Förderpotenziale haben erfahrungsgeleitete Begegnungen zwischen Kind und Pferd? Um die Forschungsfrage zu beantworten, wurde eine systematische Literaturrecherche benutzt und die Ergebnisse aus den vier theoretischen Hauptteilen zusammengefasst. Die Hauptteile stellen die Entwicklung der Wahrnehmung von Kindern, sinnlich und ästhetische Raum für Kinder, tiergestützte Gesundheitsförderung und pferdegestützte Interventionen dar. Die Ergebnisse geben einen Überblick über mögliche Förderpotenziale. Die Kind-Pferd-Beziehung wirkt sich positiv auf die Lebensqualität sowie auf die Gesundheit aus und stärkt sinnliche sowie ästhetische Erfahrungen/Kompetenzen. Auf dieser Grundlage ist es empfehlenswert, die Gesundheitsförderung mit dem Fokus auf tiergestützte Interventionen zu vergrößern. Weiterführende Forschung im Bereich der Kind-Pferd-Begegnung könnte eine empirische Darstellung sein, wie explizit eine sinnlich sowie ästhetische Begegnung verläuft

School Nurse Influence on Adolescent Type 1 Diabetic Control

Diabetes care is complex and requires consistent management of multiple factors (such as insulin, blood sugar and carbohydrate counting). School-aged children typically show poorer metabolic control, indicating a need for helping students to manage their diabetic needs. The purpose of this systematic review is to identify strategies within the care coordination role of the Licensed School Nurse that can be implemented by the school nurse, during the school day, to improve diabetic self-care among children and adolescents. Pender’s Health Promotion Model (Petiprin, 2016) was used as a framework for interventions for the school nurse and provided information about important factors that can affect an adolescent’s diabetes self-management, such as their social support, willingness and functional and cognitive abilities. A literature search was conducted to gather evidence about the effects of diabetes care management interventions in the school setting. Interventions that were or can be provided by the school nurse showed improvements that included: improved adherence to self-care, improved A1c, more frequent blood sugar monitoring and insulin administration, improved life satisfaction, better school attendance and a higher grade point average. The findings can be used to support the care coordination role of the school nurse in direct care and supervision, creating a supportive school environment and collaborative communication. However, there is a need for more randomized control trials specifically testing the effect of specific school nurse interventions on diabetic outcomes

Transformation and tumorigenicity testing of simian cell lines and evaluation of poliovirus replication

The key role of cell cultures in different scientific fields is worldwide recognized, both as in vitro research models alternative to laboratory animals and substrates for biological production. However, many safety concerns rise from the use of animal/human cell lines that may be tumorigenic, leading to potential adverse contaminations in cell-derived biologicals. In order to evaluate the suitability of 13 different cell lines for Poliovirus vaccine production, safety and quality, in vitro/in vivo tumorigenicity and Poliovirus propagation properties were evaluated. Our results revealed that non-human primate cell lines CYNOM-K1, FRhK-4, 4MBr-5 and 4647 are free of tumorigenic features and represent highly susceptible substrates for attenuated Sabin Poliovirus strains. In particular, FRhK-4 and 4647 cell lines are characterized by a higher in vitro replication, resulting indicated for the use in large-scale production field

Machiavellian Ways to Academic Cheating:A Mediational and Interactional Model

Academic cheating has become a pervasive practice from primary schools to university. This study aims at investigating this phenomenon through a nomological network which integrates different theoretical frameworks and models, such as trait and social-cognitive theories and models regarding the approaches to learning and contextual/normative environment. Results on a sample of more than 200 Italian university students show that the Amoral Manipulation facet of Machiavellianism, Academic Moral Disengagement, Deep Approach to Learning, and Normative Academic Cheating are significantly associated with Individual Academic Cheating. Moreover, results show a significant latent interaction effect between Normative Academic Cheating and Amoral Manipulation Machiavellianism: “amoral Machiavellians” students are more prone to resort to Academic Cheating in contexts where Academic Cheating is adopted as a practice by their peers, while this effect is not significant in contexts where Academic Cheating is not normative. Results also show that Academic Moral Disengagement and Deep Approach to learning partially mediate the relationship between Amoral Manipulation and Academic Cheating. Practical implications of these results are discussed

Detection of poliovirus by ICC/qPCR in concentrated water samples has greater sensitivity and is less costly using BGM cells in suspension as compared to monolayers

The integrated cell culture quantitative reverse transcriptase PCR (ICC/qRT-PCR) method is used in our lab to detect enteroviruses in environmental waters. Typically we utilize monolayers of 3 cell lines; buffalo green monkey kidney (BGM), human colonic carcinoma (CACO-2) and African rhesus monkey kidney (MA104) with the intent of providing one or more permissive hosts to a wide range of enteroviruses. In this study the BGM cell line was used to compare poliovirus infectivity in conventional monolayer cultures to BGM cells in suspensions. Propagated virus was subsequently amplified by qRT-PCR. Our PCR data showed lower cycle threshold (Ct) values in the suspensions which corresponded to a higher rate of infectivity than that observed in the monolayers. The difference in Ct values was determined statistically significant by One-way ANOVA (0.000). Infecting BGM cells in suspensions required less hands-on time, less chance of contamination and was more cost effective than utilizing the conventional monolayer technique

Can constructive deviance be empowered? A multi-level field study in Australian supermarkets

We test four hypotheses about how leaders facilitate constructive deviance in the teams they manage. Constructive deviance describes ways of creating value by departing from common ways of working. We test a multi-level model that suggests links between various leadership behaviors, psychological empowerment, and constructive deviance at the individual and team levels. Our findings add nuance to the prevalent assumption that empowered employees engage in more constructive deviance than unempowered employees do by suggesting that, rather than stimulating constructive deviance, empowerment makes deviance unnecessary. We detail implications for management
