How does past forecast behavior affect analysts' employment outcome?

We study the relationship of sell-side analysts’ performance and their employment outcomes in the U.S. from 1983 to 2013. Analysts with a weak accuracy score are more likely to leave the job and less likely to experience a job-upgrade. Controlling for accuracy and experience, bolder and younger analysts are also more likely to experience job-termination. Additionally an Institutional Investors’ all-star has a lower chance of job-termination in case of a weak performance. Finally from 2003 onwards, after Wall Street’s regulation enforcement, employment outcome becomes less sensitive to an analyst’s past performance

Knowledge management : critical perspectives on e-business activities

This article is both a review and an agenda-setting piece. It argues that knowledge management suffers from conceptual and definitional ambiguity, oversimplification of its development processes, and methodological limitations. Nevertheless, there is a consensus in business and academia that knowledge is a key component of success and allows firms to achieve and sustains competitive advantages. In a digital era, these advantages arise from the potential of data and information that can be gathered, processed, shared, and used to improve e-business activities. Thus, this research bridges the gap in the assessment of knowledge management and e-business relationship, by applying an SEM to a large database sample of KM activities performed by European firms.N/

Estándares territoriales de innovación : análisis de las regiones de Portugal

Competitiveness among regions and innovation dynamics are intimately related and depend on a solid and effective innovation system. This study aims to measure innovativeness in different Portuguese regions and to evaluate the nature of the innovation process and the relationship between innovativeness and its region of origin. To characterize the territorial innovation processes and to identify innovation patterns by regions, it analyzes their main distinctive factors, based on the Community Innovation Survey results for each region. Thus, it compares the Portuguese regions by verifying the existence of subjacent clusters and finding out the characteristics that distinguish the different groups of regions. The results point to the existence of four groups of regions, and the factors identified are related to the innovation process, namely objectives of innovation, sources of innovation, collaborative networks, triple helix performance, and obstacles to innovation.RESUMEN: La competitividad entre las regiones y la dinámica de la innovación están íntimamente relacionadas y dependen de un sistema de innovación sólida y eficaz. Este estudio tiene como objetivo medir la capacidad de innovación en diferentes regiones portuguesas y evaluar la naturaleza del proceso de innovación y la relación entre la capacidad de innovación y su región de origen. Para la caracterización de los procesos de innovación territoriales y identificar estándares de innovación en las regiones, este artículo analiza sus factores distintivos principales, con base en los resultados de las encuestas comunitarias sobre innovación para cada región. Por lo tanto, se comparan las regiones portuguesas mediante la verificación de la existencia de agrupaciones subyacentes y descubrir las características que distinguen a los diferentes grupos de regiones. Los resultados apuntan a la existencia de cuatro grupos de regiones, y los factores identificados están relacionados con el proceso de innovación, es decir, los objetivos de la innovación, las fuentes de innovación, redes de colaboración, el funcionamiento de la triple hélice, y los obstáculos a la innovación.info:eu-repo/semantics/publishedVersio

Promoting student questioning in the learning of natural sciences

This work aims to analyze the written questions asked by 9th grade students in three different question-promoting strategies in the subject of Natural Sciences, in order to assess the cognitive level and the functions of these questions. For this purpose, a qualitative research was implemented. Students’ written questions posed in the three strategies were collected. A close relationship was not found between the type of strategy and the cognitive level of the students’ questions. Nevertheless, the percentage of closed questions decreased throughout the three strategies while the percentage of open questions increased

Expansion Opportunities In The Eu Power Sector For An Integrated Power Utility By 2025

CEMSThis project provides the identification of investment opportunities by 2025 in selected EU power markets for an integrated power utility. To be able to come up with a sound recommendation, it was essential to elaborate on key energy market trends as well as their implications and deep dive into selected markets. After coming across the potential investment opportunities, a simple financial model was developed through a detailed business case to provide quantification and translate potential risks or mitigations

Going viral : the influence of emotional content and gender on social transmission

Purpose – The purpose of this work is to examine the influence that gender and different emotional stimuli exert on people’s online sharing intentions. Precisely, we take a closer look at whether (1) people share more positive or negative content; (2) men or women react more strongly to these emotional stimuli; and (3) emotional valence has a heterogeneous effect across genders. Design/Methodology - This dissertation employs an experimental study: 2 (emotional valence: positive vs. negative) x 2 (gender: male vs. female) between-subjects design. Findings – Results show that emotional valence does indeed influence sharing intentions, and more importantly, that negative emotions lead to a higher willingness to share. Further, results demonstrated that women share more content online when compared to men but no heterogeneous effects of emotional valence were observed. Research limitations - The main limitation of this research is that it is based on self-reported answers to hypothetical scenarios, since we intend to measure potential behavior of sharing. Meaning that, although an individual’s intention to commit to a certain behavior is the most adequate predictor of one’s behavior, it is beyond the scope of this study to measure actual sharing behavior. Practical implications - This research produced valuable insights by providing relevant information on how to create content that will probably be highly shared, on the opposite to the regular content that most agencies and marketer use to promote their products.Objetivo – O objetivo desta tese é examinar a influencia que gênero e diferentes estímulos emocionais exercem sobre as intenções de partilha online das pessoas: (1) se os indivíduos partilham mais conteúdos positivos ou negativos; (2) quem, de entre homens ou mulheres, reage mais fortemente a estímulos emocionais; e (3) se a valência emocional e o género têm algum tipo de correlação. Metodologia - Esta dissertação utiliza um estudo experimental: 2 (valência emocional: positiva vs. negativa) x 2 (género: masculino vs. feminino) entre sujeitos. Resultados – Os resultados mostram que a valência emocional afeta, de facto, as intenções de partilha de conteúdo online e, mais importante, que as emoções negativas levam a uma maior predisposição para partilhar. Além disso, os resultados demonstram que as mulheres partilham mais conteúdos online quando comparadas com os homens, contudo, não foram observados efeitos heterogêneos de valência emocional. Limitações- A principal limitação desta pesquisa é o fato de ser baseada em respostas próprias a cenários hipotéticos, uma vez que pretendemos medir uma intenção de partilha. Isso significa que, embora a intenção de um indivíduo de se comprometer com um determinado comportamento seja o indicador mais adequado para o comportamento do próprio, isso ultrapassa o âmbito deste estudo. Aplicabilidade do trabalho - Esta pesquisa fornece informações relevantes sobre como criar conteúdo com grande probabilidade de ser partilhado online, ao contrário do conteúdo regular que a maioria das agências e profissionais de marketing utilizam para promover os seus produtos

Does market volatility have predictive power for momentum returns? : evidence for the United Kingdom and Japan

Recent studies for the United States indicate that market volatility predicts momentum returns. The objective of this paper is to analyze if this happens in two different countries, the United Kingdom and Japan. Using a simple time series regression not only with variables regarding market volatility and market state but also macroeconomic variables, the return dispersion, sentiment index, default risk, and expected future volatility it turns out that indeed, in the case of the UK, market volatility has predictive power for the momentum payoff after controlling for all other variables except one, the VSTOXX. This measure of expected volatility can subsume the power of market volatility but only in the positive market state. Regarding Japan, the volatility of the market only has predictive power when it is used in combination with macroeconomic variables. This situation maintains with the rest of the variables except for the default risk proxies that in a down market take away the predictive power of market volatility. The conclusions that were obtained from the study of each country differ.Estudos recentes para os Estados Unidos indicam que a volatilidade do mercado ajuda a prever o lucro da estratégia momentum. O presente estudo tem como objetivo analisar se o mesmo acontece em dois outros países, o Japão e o Reino Unido. Utilizando uma simples regressão linear, que não apenas contém variáveisrelacionadas com a volatilidade e com o estado de mercado, mas também variáveis macroeconómicas, dispersão do retorno, índice de sentimento, risco de falência das empresas e volatilidade futura esperada, concluiu-se que de facto isso acontece no Reino Unido. A volatilidade do mercado pode ser usada para prever o lucro do momentum quando é controlado o efeito de outras variáveis exceto uma, a VSTOXX. A volatilidade esperada futura absorve o poder da volatilidade do mercado, mas apenas num estado de mercado considerado positivo. No que diz respeito ao Japão, a volatilidade do mercado apenas tem poder de previsão quando são introduzidas variáveis macroeconómicas. Esta situação mantém-se quando são inseridas as restantes variáveis com a exceção da variável referente ao risco de falência das empresas, que em mercados em estado considerado negativo consegue retirar o poder da volatilidade do mercado em prever o rendimento da estratégia. As conclusões obtidas para os dois países diferem
