Data from: Survival after pathogen exposure in group-living insects: don’t forget the stress of social isolation!
2016
A major cost of group-living is its inherent risk of pathogen infection. To limit this risk, many group-living animals have developed the capability to prophylactically boost their immune system in the presence of group members and/or to mount collective defenses against pathogens. These two phenomena, called density dependent prophylaxis and social immunity, respectively, are often used to explain why, in group-living species, individuals survive better in groups than in isolation. However, this survival difference may also reflect an alternative and often overlooked process: a cost of social isolation on individuals’ capability to fight against infections. Here, we disentangled the effect…
Data from: When earwig mothers do not care to share: parent-offspring competition and the evolution of family life
2018
1. Kin competition often reduces – and sometimes entirely negates – the benefits of cooperation among relatives, and hence is often regarded as central process in social evolution. Surprisingly, however, our understanding of the role of kin competition in the evolution of family life remains fragmentary, despite the close scrutiny it received in studies on sibling rivarly. This is because much less attention has been given to local competition between parents and their offspring, and its potential impact on the early evolution of parental care and family life. 2. Here, we examined mother-offspring competition over food access in the European earwig Forficula auricularia, an insect with facu…
The Forgotten Representatives of the School of Mathematics in Sciences of Management
2017
Szybki rozwój technologii, wzrost poziomu życia i zmiany demograficzne przyczyniają się do dynamicznych zmian zachodzących we współczesnym społeczeństwie. Specjaliści w dziedzinie demografii, zwracają szczególną uwagę na zjawisko „starzejącego się społeczeństwa”, co przyczyni sie do wzrostu zapotrzebowania na usługi medyczne świadczone przez lekarzy specjalizujących się w leczeniu ludzi starszych, oraz miejsca w ośrodkach opiekuńczo-leczniczych (sanatoriach czy hospicjach). Głównym celem niniejszego opracowania była ocena pozycji Polski na tle krajów Unii Europejskiej na podstawie wybranych wskaźników charakteryzujących system opieki zdrowotnej. W badaniach starano sie odpowiedzieć na pytan…
When earwig mothers do not care to share: Parent–offspring competition and the evolution of family life
2017
Kin competition often reduces – and sometimes entirely negates – the benefits of cooperation among family members. Surprisingly, the impact of kin competition on the fitness effects of family life only received close scrutiny in studies on sibling rivalry, whereas the possibility of parent–offspring competition has attracted much less attention. As a consequence, it remains unclear whether and how parent–offspring competition could have affected the early evolution of parental care and family life. Here, we examined the occurrence and consequences of parent–offspring competition over food access in the European earwig Forficula auricularia, an insect with facultative family life reminiscent…
Spór o wybory powszechne na stanowiska sędziowskie w amerykańskim dyskursie publicznym w okresie „demokracji jacksonowskiej”
2021
Artykuł przedstawia debatę, jaka odbyła się pomiędzy zwolennikami i przeciwnikami obsadza-nia stanowisk sędziowskich w drodze wyborów powszechnych w Stanach Zjednoczonych w okre-sie tzw. „demokracji jakcsonowskiej” (zwaną także populistyczną) od początku lat trzydziestych XIX wieku do wybuchu wojny secesyjnej. Począwszy od prezydentury Andrew Jacksona nasiliła się w USA walka polityczna pomiędzy ludem reprezentowanym przez Partię Demokratyczną a eli-tami, których interesów broniła Partia Wigów. Przedmiotem sporu stało się żądanie szerszego do-puszczenia ludu do sprawowania władzy oraz demokratyzacja dotychczasowej oligarchicznej re-publiki poprzez rozszerzenie praw wyborczych oraz wyborów p…
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes
2003
Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…
Grimaces et lèvres pincées : remarques sur la ritualisation pénale (Pascal, Wittgenstein) (Grimaces and Pursed Lips: Remarks on the judicial ritualiz…
2018
Cet article vise à clarifier le recours à une famille de métaphores qui entoure fréquemment le procès (ritualisation, théâtralisation, mise en scène, cérémonie de type religieux), et défend la thèse que la notion de ritualisation judiciaire exprime avant tout la louable intention d'accorder à la justice internationale pénale un temps et des occasions sans finalité préconçue, mais qui permettent la manifestation d'une diversité d'émotions. Il prend principalement appui sur la comparaison des Pensées et des Lettres provinciales de Pascal d'une part, sur le…

PHILOSOPHICAL INVESTIGATIONS ON INTEGRATIVE COMPLEXITY
2019
Integrative complexity (IC) refers to a psychological construct, a measurement, and an experience. As a construct IC refers to our less than conscious thinking style in the face of difference or disagreement, how we process information, make decisions, solve problems. The cross-culturally validated empirical measurement frame of IC has predictive values. ’Low IC’ indicates a simple thinking style that is rigid and closed, a ’tunnel vision’ way of thinking that cannot respect or recognize different dimensions or perspectives on a topic, predicting destructive conflict or violence. An increasingly complex thinking style is able to ’see the big picture’, to …
