Trend Switching Processes in Financial Markets
2010
For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes at a specific point from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating increasing trends (“bubble formation”) and decreasing trends (“bubble collapse”), on time scales ranging from macroscopic bubbles persisting for hundreds of days to microscopic bubbles persisting only for very short time scales. Our analysis is based on a German DAX Future data base containing 13,991,275 transactions recorded with a time resolution of 10− 2 s. For a parallel analysis, we use a data base of all S&P500 stocks …
Generating dialogical practices in mental health: experiences from southern norway, 1998-2008.
2013
Published version of an article in the journal: Administration and Policy in Mental Health and Mental Health Services Research. Also available from the publisher at: http://dx.doi.org/10.1007/s10488-013-0479-3 In Norway and many other countries, political guidelines prescribe the development of mental health strategies with both a service user's perspective and a treatment system established by the local authority. The development of new strategies frequently involves challenges regarding procedures and treatment as well as a view of knowledge and humanity. Dialogical practices might provide a solution for these challenges not only because of its procedures but also due to its attitudes tow…
Police violence in West Africa : Perpetrators' and ethnographers' dilemmas
2012
This article explores the use of violence by police officers and gendarmes in Ghana and Niger. We analyse how popular discourses, legal and organizational conditions frame the police use of violence. Acts of violence by police are situated in this inconsistent framework and can be seen as legal and appropriate, despicable and brutal, or as useful and morally legitimate. Thus, every time the police use violence, they face a major dilemma: legally and morally justified violence can be a source of long-term legitimacy; but because of multiple possible readings of a certain situation (according to different, conflicting moral and legal discourses), the very same action has potentially delegiti…
Rewriting Oromo History in the North: Diasporic Discourse about National Identity and Democracy in Ethiopia
2015
This article analyzes the way the Oromo intellectuals living in diaspora have reflected on and positioned themselves in the ethno-political conflict and related debate between the dominant Amharic- and Tigrinya-speaking “Abyssinian” groups and the descendants of the various Oromo groups, which were conquered by the former during the nineteenth century. Even though they are the largest ethnic group in Ethiopia, a large part of the Oromo perceive themselves as discriminated against and exploited by the groups holding political power, and many have fled the country. In the debate, the Oromo diaspora has had an important role. Theoretically, the article takes off from the concept of “orientati…
La verificació audiovisual en el procés d’evolució de les redaccions televisives: Al Jazeera i el trànsit del satèl·lit a l’estructura de núvol
2021
With the spread of the digital sphere and the proliferation of images from indirect sources that can be accessed by systems and users, verification routines have become essential to ensure media corporations' credibility. The advances in artificial intelligence which allow automated fact-checking (AFC) initiatives to be created help detect falsehoods, but they do not eliminate the need for human intervention. On the contrary, information professionals are necessary, and their functions increasingly include procedures such as mediating in videos and images. This study analyses the evolution of verification routines in audiovisual journalism and how new techniques have influenced the percepti…
Performing ethnography and ethnicity : an early documentation of Finnish immigrants in Nordiska museet
2010
This article discusses the first project of the Nordic Museum in Stockholm, Sweden, dealing with immigrants. It was carried out between 1972 and 1990, and it produced material based on interviews, participant observation, photographs and other written and visual sources. The article first examines why and how this extensive research project was carried out and then discusses the documentation project as performance. The project was an early attempt to document the contemporary lives of people through fieldwork, although the original aim of this pioneering project was merely to create and preserve ethnic identity by documenting “authentic” Finnish characteristics. Thus, it is a good example …
Entrepreneurship Training and Self-Employment among University Graduates
2012
In economies characterized by low labor demand and high rates of youth unemployment, entrepreneurship training has the potential to enable youth to gain skills and create their own jobs. This paper presents experimental evidence on a new entrepreneurship track that provides business training and personalized coaching to university students in Tunisia. Undergraduates in the final year of licence appliquee were given the opportunity to graduate with a business plan instead of following the standard curriculum. This paper relies on randomized assignment of the entrepreneurship track to identify impacts on labor market outcomes one year after graduation. The analysis finds that the entrepreneur…
Maternal body mass index, gestational weight gain, and the risk of overweight and obesity across childhood: An individual participant data meta-analy…
2019
Background Maternal obesity and excessive gestational weight gain may have persistent effects on offspring fat development. However, it remains unclear whether these effects differ by severity of obesity, and whether these effects are restricted to the extremes of maternal body mass index (BMI) and gestational weight gain. We aimed to assess the separate and combined associations of maternal BMI and gestational weight gain with the risk of overweight/obesity throughout childhood, and their population impact. Methods and findings We conducted an individual participant data meta-analysis of data from 162,129 mothers and their children from 37 pregnancy and birth cohort studies from Europe, No…

The signaling effects of central bank tone
2021
Abstract Does policymakers’ choice of words matter? We assess empirically whether the tone of FOMC statements contains useful information for financial market participants and explore the nature of the information conveyed. We quantify central bank tone using computational linguistics. We find that the tone of FOMC statements explains monetary surprises beyond FOMC information released on policy announcement days such as policymakers’ forecasts and votes. We also find that the FOMC tone matters more around monetary cycle turning points. We show that the tone of policy statements also helps predict future policy decisions. Our findings suggest that the central bank tone may be one of the veh…
