The Graham Bank (Sicily Channel, central Mediterranean Sea). Seafloor signatures of volcanic and tectonic controls
2018
Abstract Graham Bank is a dominant physiographic element of the NW Sicily Channel (central Mediterranean Sea), affected in the last 100 years by numerous well-documented volcanic eruptions. We present the first results of a geomorphological study where the Graham Bank region in the depth interval 7–350 m was mapped for the first time with multi-beam echosounder and high-resolution seismic and multi-channel seismic reflection profiles. We describe in high resolution the detailed geomorphological features of Graham Bank, and how the superficial expression of different process and dynamics occurring in the sub-seafloor evidence volcanic and tectonic controls on seafloor morphology across a rel…
Survival and gene expression under different temperature and humidity regimes in ants
2017
Short term variation in environmental conditions requires individuals to adapt via changes in behavior and/or physiology. In particular variation in temperature and humidity are common, and the physiological adaptation to changes in temperature and humidity often involves alterations in gene expression, in particular that of heat-shock proteins. However, not only traits involved in the resistance to environmental stresses, but also other traits, such as immune defenses, may be influenced indirectly by changes in temperature and humidity. Here we investigated the response of the ant F. exsecta to two temperature regimes (20 degrees C & 25 degrees C), and two humidity regimes (50% & 75%), for…
Origin and distribution of desert ants across the Gibraltar Straits
2017
The creation of geographic barriers has long been suspected to contribute to the formation of new species. We investigated the phylogeography of desert ants in the western Mediterranean basin in order to elucidate their mode of diversification. These insects which have a low dispersal capacity are recently becoming important model systems in evolutionary studies. We conducted an extensive sampling of species belonging to the Cataglyphis albicans group in the Iberian Peninsula (IP) and the northern Morocco (North Africa; NA). We then combined genetic, chemical and morphological analyses. The results suggest the existence of at least three and five clades in the IP and NA, respectively, whose…
Starvation resistance and tissue-specific gene expression of stress-related genes in a naturally inbred ant population
2016
Starvation is one of the most common and severe stressors in nature. Not only does it lead to death if not alleviated, it also forces the starved individual to allocate resources only to the most essential processes. This creates energetic trade-offs which can lead to many secondary challenges for the individual. These energetic trade-offs could be exacerbated in inbred individuals, which have been suggested to have a less efficient metabolism. Here, we studied the effect of inbreeding on starvation resistance in a natural population of Formica exsecta ants, with a focus on survival and tissue-specific expression of stress, metabolism and immunity-related genes. Starvation led to large tis…
Gambling and gaming during COVID-19 : The role of mental health and social motives in gambling and gaming problems
2022
Background: The uncertain and stressful global situation caused by the COVID-19 pandemic has the potential to cause anxiety and impact people's mental health. Simultaneously, social distancing policies have isolated people from their normal social interactions. These societal changes have inevitably influenced gambling and gaming practices, and many people may have turned to betting or gaming as a means of social exchange. This study examined the influence of COVID-19 anxiety on increased mental health problems and their relationship to gambling and gaming problems. The mediating role of social motives for gambling and gaming was also investigated. Material and methods: Finnish adults (N = …

Dzieje organów w kościele parafialnym w Niemczy
2018
Pierwsze wzmianki o organach w kościele parafialnym w Niemczy pochodzą z przełomu XVI i XVII wieku. W latach 1597–1598 niewielki instrument wybudował Abraham Grasse. W 1617 roku ten sam organmistrz postawił nowe organy, liczące sześć głosów w manuale i trzy w pedale. Strawił je pożar w 1633 roku. W 1648 roku do odbudowanego kościoła zakupiono używany pozytyw. W 1725 roku świątynia wzbogaciła się o 20-głosowe organy wybudowane przez Ignatzego Mentzla. Służyły one parafii do 1852 roku, wówczas zamknięto, a następnie rozebrano kościół. Organy znajdujące się w obecnej świątyni pochodzą z 1866 roku i są dziełem Gottfrieda Riemera z Brzegu. Miały pierwotnie 18 głosów i mechaniczną trakturę rejest…
Rahoitusmarkkinainformaatio BRIC-maiden laajennetussa Taylorin säännössä
2017
Tutkielmassa tarkastellaan BRIC-maiden harjoittamaa rahapolitiikkaa vuosina 2005-2015. Tutkielman päämääränä on selvittää, ovatko keskuspankit reagoineet rahapolitiikallaan inflaation ja tuotantokuilun lisäksi myös rahoitusmarkkinainformaatioon. Aineistona on käytetty reaaliaikaista aineistoa inflaation ja tuotantokuilun osalta. Rahoitusmarkkinainformaatiolla tarkoitetaan tutkielmassa kohdemaan valuuttakurssia ja keskimääräistä osinkotuottoa. Rahapolitiikkaa on arvioitu sekä sen hetkisten että eteenpäin katsovien Taylorin sääntöjen avulla. Rahoitusmarkkinainformaation roolia on tutkittu estimoimalla erilaisia rahoitusmarkkinainformaatiolla laajennettuja Taylorin sääntöjä ja arvioimalla laaj…
A gene transfer agent and a dynamic repertoire of secretion systems hold the keys to the explosive radiation of the emerging pathogen Bartonella
2013
Gene transfer agents (GTAs) randomly transfer short fragments of a bacterial genome. A novel putative GTA was recently discovered in the mouse-infecting bacterium Bartonella grahamii. Although GTAs are widespread in phylogenetically diverse bacteria, their role in evolution is largely unknown. Here, we present a comparative analysis of 16 Bartonella genomes ranging from 1.4 to 2.6 Mb in size, including six novel genomes from Bartonella isolated from a cow, two moose, two dogs, and a kangaroo. A phylogenetic tree inferred from 428 orthologous core genes indicates that the deadly human pathogen B. bacilliformis is related to the ruminant-adapted clade, rather than being the earliest diverging…
Drivers and outcomes of consumer engagement : Insights from mobile money usage in Ghana
2019
Purpose The purpose of this paper is to examine the drivers of consumer engagement and its consequences via the experiences of mobile money services’ users in Ghana and to discuss its implications for the society, financial service innovation, delivery and operations. Design/methodology/approach A pre-tested survey instrument was used with a sample of 595 mobile money services users in Ghana. SmartPLS application was used to analyze the data and report findings. Findings The study shows that perceived risk, consumer empowerment, subjective norm, performance expectancy and effort expectancy influence the affect component of consumer engagement and explain around half of its variance. The ef…
