Volatility risk premia and financial connectedness

2014

In this paper we use the Diebold Yilmaz (2009 and 2012) methodology to construct an index of connectedness among five European stock markets: France, Germany, UK, Switzerland and the Netherlands, by using volatility risk premia. The volatility risk premium, which is a proxy of risk aversion, is measured by the difference between the implied volatility and expected realized volatility of the stock market for next month. While Diebold and Yilmaz focus is on the forecast error variance decomposition of stock returns or range based volatilities employing a stationary VAR in levels, we account for the (locally) long memory stationary properties of the levels of volatility risk premia series. The…

Evolution of Seismicity During a Stalled Episode of Reawakening at Cayambe Volcano, Ecuador

2021

Cayambe Volcano is an ice-capped, 5,790 m high, andesitic-dacitic volcanic complex, located on the equator in the Eastern Cordillera of the Ecuadorian Andes. An eruption at Cayambe would pose considerable hazards to surrounding communities and a nationally significant agricultural industry. Although the only historically documented eruption was in 1785, it remains persistently restless and long-period (LP) seismicity has been consistently observed at the volcano for over 10 years. However, the sparse monitoring network, and complex interactions between the magmatic, hydrothermal, glacial, and tectonic systems, make unrest at Cayambe challenging to interpret. In June 2016 a seismic “crisis” …

Mapping the Concept(s) of Belonging

2014

Various epistemological changes – such as the linguistic, narrative, and cultural turns that have influenced humanistic and social scientific studies since the 1980s – have contributed to the increased academic interest in politics, discourses, processes, and practices of belonging. During the recent decades, the idea of belonging or notbelonging have been discussed and theorized in various fields with diverse parallel and/or overlapping conceptualizations. These include, for example, identity, placemaking, displacement, and their representational, intersectional, and fluid nature. In recent years, several scholars have aimed to discuss the topics framed by the above mentioned concepts and …

Singing is what we do (together) - redefining "together" : A comparative study

2021

This article discusses the impact that the Covid-19 pandemic has had on singing with children in schools by providing a descriptive analysis of a comparative look at children's experiences of their singing habits and emotional well-being during the first Covid-19 lockdown. Covid-19 has established itself as (for now) an ever-present variable in our daily lives. This paper offers a descriptive analysis of a comparative study of the Covid-19 lockdown(s) influence on children's singing habits and emotional well-being in Italy, Austria, and Finland. A survey was carried out on children and young people aged 10-20 from Austria, Finland, and Italy on how the Coronavirus lockdown has impacted thei…

The mechanically based non-local elasticity: an overview of main results and future challenges

2013

The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.

Longitudinal Patterns of Ethical Organisational Culture as a Context for Leaders’ Well-Being: Cumulative Effects Over 6 Years

2021

AbstractThe aim of this longitudinal study was to investigate the temporal dynamics of ethical organisational culture and how it associates with well-being at work when potential changes in ethical culture are measured over an extended period of 6 years. We used a person-centred study design, which allowed us to detect both typical and atypical patterns of ethical culture stability as well as change among a sample of leaders. Based on latent profile analysis and hierarchical linear modelling we found longitudinal, concurrent relations and cumulative gain and loss cycles between different ethical culture patterns and leaders’ well-being. Leaders in the strongest ethical culture pattern exper…

Is Autonomy Always Beneficial for Work Engagement? A Six-year Four-Wave Follow-Up Study.

2021

Work engagement is expected to result from job resources such as autonomy. However, previous results have yielded that the autonomy–work engagement relationship is not always particularly strong. Whereas previous longitudinal studies have examined this relationship as an average at a specific point in time, this study examined whether this relationship is different within individuals from one time to another over the years. Furthermore, experiences of work engagement are expected to affect how employees benefit from autonomy, but no studies have so far investigated whether the initial level of work engagement affects the autonomy–work engagement relationship. This study aimed to first ident…

Sense of belonging in a digitalised care work community

2021

This chapter uses the theoretical framework of sense of belonging to explore how eldercare workers from Finnish service housing units for older people describe the use of digital devices and applications in their work and the work practices that relate to their sense of belonging. The study is based on interview data (n = 25) that was collected in 2018 for a study on digitalisation of eldercare. The chapter asks: what does a sense of belonging mean for care workers’ agency in a digital era? The analysis concentrates especially on the practices of belonging and how they are enacted in a digitalised work environment. The chapter proposes that in the digital era, a sense of belonging is partic…

Physical activity from adolescence to young adulthood: patterns of change, and their associations with activity domains and sedentary time

2021

Background Longitudinal studies demonstrate an average decline in physical activity (PA) from adolescence to young adulthood. However, while some subgroups of adolescents decrease activity, others increase or maintain high or low activity. Activity domains may differ between subgroups (exhibiting different PA patterns), and they offer valuable information for targeted health promotion. Hence, the aim of this study was to identify PA patterns from adolescence to young adulthood; also to explore the associations of (i) changes in PA domains and in sedentary time, (ii) sociodemographic factors, and (iii) self-rated health with diverging PA patterns. Methods The observational cohort study data …
