Reciprocal hybridization at different times between Senecio flavus and Senecio glaucus gave rise to two polyploid species in north Africa and south‐w…

2006

Summary • The analysis of hybrid plant taxa using molecular methods has considerably extended understanding of possible pathways of hybrid evolution. • Here, we investigated the origin of the tetraploid Senecio mohavensis ssp. breviflorus and the hexaploid Senecio hoggariensis by sequencing of nuclear and chloroplast DNA, and by analysis of the distribution of taxon-specific amplified fragment length polymorphism (AFLP) fragments. • Both taxa originated from hybridization between the diploid Senecio flavus and Senecio glaucus. Whereas S. glaucus was the female parent in the origin of S. mohavensis ssp. breviflorus, S. flavus was the female parent in the origin of S. hoggariensis. • The dist…

Multi-channel search for squarks and gluinos in root s=7 TeV pp collisions with the ATLAS detector at the LHC

2013

A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb[superscript −1] of √s = 7 TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam line that are sensitive to several topologies expected in supersymmetry. Mutually exclusive final states are defined, allowing a combination of all channels to increase the search sensitivity. No deviation from the Standard Model expectation is observed. Upper limits at 95 % confidence level…

The influence of business groups on board composition in offshore financial multinational enterprises

2023

Based on resource dependence theory we argue for an influence of business groups (BGs) on the board composition of constituent offshore financial multinational enterprises (FMNEs). Using a unique sample of 171 Caribbean FMNEs in an inter-island BG setting, we find BGs’ control in constituent firms to be indicative of the importance of the internal financing and intermediation within the group network. This control leads to a higher proportion of lawyers hired to the boards of directors in BG-constituent firms and supports the argument that lawyers provide skills in complex offshore regulatory frameworks that facilitate BGs’ optimal tax management. Furthermore, we observe that an increased a…

Forward rapidity isolated photon production in proton-nucleus collisions

2018

We calculate isolated photon production at forward rapidities in proton-nucleus collisions in the Color Glass Condensate framework. Our calculation uses dipole cross sections solved from the running coupling Balitsky-Kovchegov equation with an initial condition fit to deep inelastic scattering data and extended to nuclei with an optical Glauber procedure that introduces no additional parameters beyond the basic nuclear geometry. We present predictions for future forward RHIC and LHC measurements. The predictions are also compared to updated results for the nuclear modification factors for pion production, Drell-Yan dileptons and $J/\psi$ mesons in the same forward kinematics, consistently c…

Commodity market based hedging against stock market risk in times of financial crisis: The case of crude oil and gold

2018

Based on daily data from 1989-2016 we find that the correlations between some relevant commodity market futures and equity returns in the aggregate U.S. market, and specifically in the energy sector stocks have changed strongly during the stock market crisis periods. The correlation between crude oil futures and aggregate U.S. equities increases in crisis periods, whereas in case of gold futures the correlation becomes negative, which supports the safe haven hypothesis of gold. For energy sector equities, the dynamics of hedge ratios does not support using either crude oil or gold futures for cross-hedging during stock market crises.

Do commodity assets hedge uncertainties? What we learn from the recent turbulence period?

2022

AbstractThis study analyses the impact of different uncertainties on commodity markets to assess commodity markets' hedging or safe-haven properties. Using time-varying dynamic conditional correlation and wavelet-based Quantile-on-Quantile regression models, our findings show that, both before and during the COVID-19 crisis, soybeans and clean energy stocks offer strong safe-haven opportunities against cryptocurrency price uncertainty and geopolitical risks (GPR). Soybean markets weakly hedge cryptocurrency policy uncertainty, US economic policy uncertainty, and crude oil volatility. In addition, GSCI commodity and crude oil also offer a weak safe-haven property against cryptocurrency uncer…

Why Am I the Only One You’re Talking to, Talk to Them, They Haven’t Said a Word? : Pitfalls and Challenges of Having the Child in the Focus of Family…

2021

Children with conduct disorders are at risk of being positioned in the family therapy as ‘the problem’. This study describes how the difficulties were talked about and how the child coped in this situation. The results showed: the parents produced symptom-oriented problem talk about the child’s behavior, rendering systemic reformulation of the problem challenging. The negative interaction made the climate unsafe and impaired consideration of the child’s behavior as a meaningful way for the child to become seen and heard. This study enriches understanding of the therapeutic challenge therapists face with high-risk families from the very beginning of the treatment. peerReviewed

The influence of financial features and country characteristics on B2B ICOs’ website traffic

2021

Abstract Technology, blockchain, and initial coin offerings (ICOs) have changed the established ways of financing companies and doing business. The changes that affect organizational communications, specifically marketing communications, remain unclear, especially in the context of business-to-business (B2B) organizations. The current trend is for B2B companies to view social media as an optimal way to enhance lasting and valuable relationships with other companies. There is little research on social media marketing strategies by B2B organizations. To fill this gap, this study uses a sample of 57 B2B ICOs completed by December 2019 and qualitative comparative analysis to examine how the com…
