Measuring Public Speaking Anxiety: Self-report, behavioral, and physiological

2021

Self-reports are typically used to assess public speaking anxiety. In this study, we examined whether self-report, observer report, and behavioral and physiological reactivity were associated with each other during a speech challenge task. A total of 95 university students completed a self-report measure of public speaking anxiety before and after the speech challenge. Speech duration (i.e., behavioral measure), physiological reactivity, as well as speech performance evaluated by the participants and observers were also recorded. The results suggest that self-reported public speaking anxiety predicts speech duration, as well as speech quality, as rated by the participants themselves and ob…

Les partis politiques en Grande-Bretagne

2013

National audience; La vie politique en Grande-Bretagne est marquée par l’une des histoires les plus riches et anciennes d’Europe, mais son originalité reste largement méconnue – surtout par le public francophone, qui la réduit trop souvent à l’affrontement des deux grands partis dominants : Labour et Tories.D’où le présent ouvrage qui analyse l’ensemble des partis politiques, en soulignant la force des changements intervenus récemment en Grande-Bretagne. Fondé sur une définition précise du parti politique, il tient compte des multiples dimensions des organisations partisanes (idéologie-valeurs, ressources, soutiens). Il insiste aussi sur la modernisation des grands partis majoritaires (New …

Coincidental loss of bacterial virulence in multi-enemy microbial communities.

2014

The coincidental virulence evolution hypothesis suggests that outside-host selection, such as predation, parasitism and resource competition can indirectly affect the virulence of environmentally-growing bacterial pathogens. While there are some examples of coincidental environmental selection for virulence, it is also possible that the resource acquisition and enemy defence is selecting against it. To test these ideas we conducted an evolutionary experiment by exposing the opportunistic pathogen bacterium Serratia marcescens to the particle-feeding ciliate Tetrahymena thermophila, the surfacefeeding amoeba Acanthamoeba castellanii, and the lytic bacteriophage Semad11, in all possible combi…

Apvienotās Karalistes izstāšanās no Eiropas Savienības ietekme uz brīvas preču aprites regulējumu

2020

Apvienotā Karaliste ir pirmā valsts, kas saskaņā ar Līgumu par Eiropas Savienību (turpmāk - LES) 50. pantu izstājusies no Eiropas Savienības. Pētījuma veikšanas brīdī Apvienotā Karaliste ir pārejas periodā un tiek veiktas sarunas par nākotnes tirdzniecības attiecību satvaru. Darba ietvaros veikts pētījums par dažādu tirdzniecības attiecību modeļu ietekmi uz Eiropas Savienības un Apvienotās Karalistes nākotnes tirdzniecības attiecībām, padziļināti pētot brīvās tirdzniecības līguma regulējumu un piemērošanas aspektus. Mērķis ir izpētīt iespējamos tirdzniecības attiecību regulējumu modeļus pēc Apvienotās Karalistes izstāšanās, lai analizētu tirdzniecības attiecību attīstību un tiesisko regulēj…

Mismatches between objective parameters and measured perception assessment in room acoustics: a holistic approach

2014

Psychoacoustic research in the field of concert halls has revealed that many aspects concerning listening perception have yet to be totally understood. On the one hand, the objective room acoustics of performance spaces are reflected in parameters, some standardized and some not, but these are related to a limited number of perceptual attributes of human response. In general, these objective parameters cannot accurately describe the acoustic details due to their inherent simplification. Under these premises, impulse responses (576 receivers) are measured in 16 concert halls, according to standard procedures, and the perception and satisfaction of the occupants of the rooms are evaluated by …

Multimedia in Learning English as a Foreign Language as Preferred by German, Spanish, and Polish Teenagers

2014

This paper presents the findings of a small-scale study investigating the preferences of German, Polish, and Spanish teenage English as a foreign language (EFL) learners concerning their use of multimedia, such as Skype, Facebook, YouTube, e-mails, and TV-programmes in learning English. A group of 88 respondents was requested to complete an on-line questionnaire in order to specify how often some selected types of multimedia are used by adolescents in their autonomous EFL learning, and to determine their views on the extent to which some selected multimedia affect the development of their language skills (reading, writing, listening, and speaking) and their English pronunciation. The outcom…

Production, stability, gene sequencing and in situ anti-Listeria activity of mundticin KS expressed by three Enterococcus mundtii strains

2014

Three enterococci (WFE3, WFE20 and WFE31) selected as presumptive bacteriocin producers were found to be active against Listeria monocytogenes. In this study, due to their potential industrial/food applications, the three bacterial isolates were extensively characterized. Identification was performed by means of a combined 16S rRNA gene sequencing and multiplex PCR approach, and was confirmed with the sequencing of a partial region of a protein-encoding gene, namely pheS. The three isolates belonged unequivocally to the species Enterococcus mundtii. The randomly amplified polymorphic DNA (RAPD) analysis recognized three distinct strains. The supernatants were mainly active against Listeria …

Biological control of Listeria monocytogenes in soil model systems by Enterococcus mundtii strains expressing mundticin KS production

2022

Abstract The agricultural practices applied in pre-harvest greatly influence the presence and the levels of microorganisms in fresh produce. Among these, Listeria monocytogenes represents one of the most lethal foodborne pathogens associated with vegetables. The main hypothesis of this work is that bacteriocin producer Enterococcus mundtii strains can be effective against L. monocytogenes in soil. To this purpose, bacteriocin production by E. mundtii WFE3, WFE20 and WFE31, three strains showing a strong bacteriocin activity in terms of inhibitory power and inhibition spectra, was evaluated in sterile extracts from agricultural soil and peat moss, in organic nutrient solution (ONS) and miner…

Microbial interactions in food model systems: In situ antilisterial activity of mundticin KS producing strains

2013

It is known that microbial interactions are important for the success of food fermentations, as well as for the establishment of the safety of the final products. In this study, we characterized extensively three enterococci (WFE3, WFE20 and WFE31) of flour origin, which were found to be active against Listeria monocytogenes, in order to investigate on their ability to produce bacteriocins in complex food model systems for their future industrial/food applications. The identification of the three bacterial isolates was performed by means of a combined 16S rRNA gene sequencing and multiplex PCR approach. Two isolates belonged unequivocally to the species E. mundtii, while one isolate could n…
