Why (and how) to regulate Power Exchanges in the EU market integration context?
No full textPower Exchanges (PXs) are key market institutions in open and market-based electricity industries. This paper aims at contributing to the ongoing debate on why and how to regulate Power Exchanges in the EU market integration context. . The paper starts by stating that two different types of PXs have to be distinguished, i.e. "Merchant" PXs and the "Cost of Service Regulated" PXs. The paper continues by comparing the typical incentives of these two types of PXs to perform the basic PX tasks in an isolated national market and in a market integration context. The paper concludes by deriving from this analytical frame the most relevant regulatory actions..Regulation, Exchanges, Grid access, Power Markets.
Implicit Auctioning on the Kontek Cable: Third Time Lucky?
No full textCross-border capacities in Europe are currently inefficiently used. Implicit auctioning is about eliminating these cross-border trade inefficiencies by internalizing the arbitrage into the auction procedures of the Power Exchanges that are organizing trade nationally. On the Kontek Cable, implicit auctioning has been implemented without price coordination between the involved Power Exchanges. This implementation, referred to as “volume or dome coupling” as opposed to “price coupling”, has been argued to be institutionally easier to implement. The Kontek Cable experimented with three different implicit auctioning implementations whose performance we analyze empirically in this paper. We find that the third implementation is significantly outperforming the previous two implementations, but in this third implementation stakeholders partly abandoned the volume coupling approach they initially believed to be a viable alternative to price coupling.electricity, transmission, congestion management, market coupling
Neighbourhood poverty, work commitment and unemployment in early adulthood: A longitudinal study into the moderating effect of personality
No full textWe studied how personality moderates the effect of neighbourhood disadvantage on work commitment and unemployment in early adulthood. Using a personality typolo-gy of resilients, overcontrollers, and undercontrollers, we hypothesised that the association between neighbourhood poverty and both work commitment and unemployment would be stronger for overcontrollers and undercontrollers than for resilients. We used longitudinal data (N=249) to test whether the length of exposure to neighbourhood poverty between age 16 and 21 predicts work commitment and unemployment at age 25. In line with our hypothesis, the findings showed that longer exposure is related to weaker work commitment among undercontrollers and overcontrollers and to higher unemployment among undercontrollers. Resilients’ work commitment and unemployment were not predicted by neighbourhood poverty.OTBArchitecture and The Built Environmen
Biological sensitivity to context: Cortisol awakening response moderates the effects of neighbourhood density on the development of adolescent externalizing problem behaviours
No full textAbstractThis four-year longitudinal study attempted to test person-environment interaction theory and biological sensitivity theory by assessing whether individuals’ biological stress activity CARAUCg (Cortisol Awakening Response Area Under the Curve with respect to ground) moderates the effects of neighbourhood density on the development of adolescent externalizing problem behaviours. Participants were 358 Dutch adolescents with a mean age of 15 years at the first measurement. Our analyses showed that CARAUCg moderated the effects of neighbourhood density on the level of parent-reported delinquency and aggression and adolescent self-reported delinquency. More specifically, for adolescents with high CARAUCg, higher neighbourhood density significantly predicted higher levels of parent-reported and adolescent self-reported delinquency and aggression, whereas the association was reversed or non-significant for adolescents with low CARAUCg. Our findings suggest that adolescents with different levels of CARAUCg respond differentially to the density of the neighbourhood they live in, supporting for person-environment interaction perspectives and biological sensitivity theory

Being Poorer Than the Rest of the Neighborhood: Relative Deprivation and Problem Behavior of Youth
No full textAccording to the neighbourhood effects hypothesis, there is a negative relation between neighbourhood wealth and youths' problem behaviour. It is often assumed that there are more problems in deprived neighbourhoods, but there are also reports of higher rates of behavioural problems in more affluent neighbourhoods. Much of this literature does not take into account relative wealth. Our central question was whether the economic position of adolescents' families relative to the neighbourhood in which they lived, was related to adolescents' internalising and externalising problem behaviour. We used longitudinal data for youths between 12-21 years of age, combined with population register data.We employ between-within models to account for time-invariant confounders, including parental background characteristics. Our findings show that for adolescents, moving to a more affluent neighbourhood was related to increased levels of depression, social phobia, aggression, and conflict with father and mother. This could be indirect evidence for the relative deprivation mechanism, but we could not confirm this, and we did not find any gender differences. The results do suggest that future research should further investigate the role of individuals' relative position in their neighbourhood in order not to overgeneralise neighbourhood effects and to find out for whom neighbourhoods matter
BeReal, Be Happy? Examining the relationships between authentic self-presentations on BeReal and adolescents' self-esteem
No full textUnlike most social media, the new platform BeReal encourages users to present an authentic self. Since such self-presentations are assumed to have positive effects, this study examined whether adolescents' authentic self-presentations on BeReal relate to a higher self-esteem and whether self-concept clarity plays a role in that relationship. The relationships between exposure to perceived authentic self-presentations of others, social comparison on BeReal, and self-esteem were also explored. Of the 367 adolescents who participated in our cross-sectional survey, a total of 148 (40.33%, Mage = 16.23, SDage = 1.46; 82.4% girls) had an account on BeReal. Using structural equation modeling (SEM), we found that these adolescents' authentic self-presentations were not significantly related to their self-concept clarity nor indirectly to their self-esteem. Self-esteem and self-concept clarity were, however, positively correlated. Regarding exposure to others' content on BeReal, only upward and downward social comparisons on these platforms were significantly related to a lower and higher self-esteem, respectively.The author(s) disclosed receipt of the following financial support for the research, authorship, and/ or publication of this article: This work was supported by the European Research Council (ERC) under grant agreement number 852317
De territoriale ambities van de diadochen in de eerste jaren na de dood van Alexander de Grote (323-320 v.C.)
No full textScholars almost universally agree that there were two tendencies among the Successors of Alexander the Great: while some are assumed to have aimed at gaining control of Alexander’s entire empire, others supposedly were content with a part of it. This paper will question the foundations of this communis opinio, as both Diodorus Siculus and Cornelius Nepos explicitly state that all the Successors wanted to lay their hands on the entire realm and no ancient author mentions any separatist tendencies. A new assessment might show that many of the alleged signs of separatism in the early Successor era can also be interpreted in other ways
Narrator and narratorial persona in Diodoros' Bibliotheke (and their implications for the tradition of Greek historiography)
No full textThis paper explores the possibility of gaining fresh insight into Diodoros’
Bibliotheke by means of the concepts of narrator and narratorial persona.
It falls in three parts. Part 1 offers a formal, narratological analysis of the Diodorean narrator. Part 2 characterises Diodoros’ narratorial persona and argues that it is more fruitful to regard it as a deliberate ‘persona’ claiming authority by placing itself in the historiographical tradition than as the autobiographical voice of the author. Part 3 analyses the narratorial register of four stretches of narrative from the Bibliotheke based on four different sources. It demonstrates that different branches of Greek historiography had traditionally used different modes of narration and argues that Diodoros may consciously have aimed to imitate the narrative mode of his predecessors in each area rather than mechanically taking
over the narrative mode of his sources
Ch. 4. Filling in the Gaps: Studying Anachronism in Diodorus’ Narrative of the First Sicilian ‘Slave War’
No full textDiodorus Siculus’ narrative of the First Sicilian ‘Slave War’ is often considered to offer an ‘accurate, reliable, and comprehensive’ account of the war. This article aims to demonstrate that the text is not necessarily authoritative by reassessing the narrative function of an anachronistic explanatory passage that is often ‘fixed’ in modern accounts with a plausible, but hypothetical alternative. It is argued that we cannot ‘fix’ this anachronism without thereby jeopardising the text’s narrative structure. In sum, the anachronism was inserted because the author did not understand the events he narrated or their immediate historical context.
