Identification of picobirnavirus from faeces of Italian children suffering from acute diarrhea
1996
Polyacrylamide gel electrophoresis of nucleic acid extracted from stool samples of diarrhoeic children revealed in 3 out of 690 (0.43 %) specimens two electrophoretic bands with a migration pattern characteristic of picobirnavirus ds-RNA. In none of the 92 control children were similar bands detected. No other potential enteric pathogens were found in the patients with picobirnavirus infection.
‘I don’t know the answer to that question’: a corpus-assisted discourse analysis of White House Press Briefings
2013
White House Press Briefings, daily meetings with the press held by the White House Press Secretary, are the main information conduit for the White House (Kumar 2007). They are considered a “political chess game” where the Press Secretary and the press face a “wrestling match” (Partington 2006: 16). Our analysis is carried out on a corpus comprising all the Press Briefings across three presidencies from Clinton to Obama. The additional mark-up includes information about individual speakers and their role, allowing us to compare different discourse strategies adopted by the participants in the briefings at different points in time. This leads us to determine the extent of the differences in t…
Up and Down States During Slow Oscillations in Slow-Wave Sleep and Different Levels of Anesthesia
2021
Slow oscillations are a pattern of synchronized network activity generated by the cerebral cortex. They consist of Up and Down states, which are periods of activity interspersed with periods of silence, respectively. However, even when this is a unique dynamic regime of transitions between Up and Down states, this pattern is not constant: there is a range of oscillatory frequencies (0.1–4 Hz), and the duration of Up vs. Down states during the cycles is variable. This opens many questions. Is there a constant relationship between the duration of Up and Down states? How much do they vary across conditions and oscillatory frequencies? Are there different sub regimes within the slow oscillation…
2030 for the EU: Real steps of change? A short commentary on Biodiversity Strategy and Farm to Fork
2020
A short commentary on the EU 2030 Biodiversity Strategy and the Farm to Fork Strategy. The Covid-19 pandemic adds other similarly contradictory stances: it is an occasion to change the world for the better, but it also forces us to focus on the here and now to save lives and jobs. The Strategy, whose subtitle is Bringing nature back into our lives, seems to speak to people in lock-down, building on their sense of suffocation from strict indoor living and on the beautiful and nourishing memories of moments spent in nature. However, the Strategy also, and mostly, speaks to industries and entrepreneurs who are projected to the post-Covid time to bring business back into their lives. Regardless…
Absence Seizure Detection Algorithm for Portable EEG Devices
2021
Absence seizures are generalized nonmotor epileptic seizures with abrupt onset and termination. Transient impairment of consciousness and spike-slow wave discharges (SWDs) in EEG are their characteristic manifestations. This type of seizure is severe in two common pediatric syndromes: childhood (CAE) and juvenile (JAE) absence epilepsy. The appearance of low-cost, portable EEG devices has paved the way for long-term, remote monitoring of CAE and JAE patients. The potential benefits of this kind of monitoring include facilitating diagnosis, personalized drug titration, and determining the duration of pharmacotherapy. Herein, we present a novel absence detection algorithm based on the propert…
Spanish Validation of the Leader Empowering Behavior Questionnaire (LEBQ)
2019
The concept of empowering leadership has attracted widespread academic and practical interest and different questionnaires have been developed to measure it. However, there are no instruments to measure empowering leadership in the Spanish language. This article presents the translation, adaptation, and validation of a scale to measure this construct. In addition, it analyzes the relationship between managers’ empowering leadership and employees’ job satisfaction. In turn, the study analyzes whether employees who participate in a greater number of continuous improvement programs have supervisors who favor more empowering behaviors. A total of 739 participants with various occupations from d…
The Creative Activity of Textile Lecturers as an Aspect of Professional Competence Development and its Impact on Study Process
2015
The creative activity of lecturers teaching textile course of studies is an essential aspect of professional competence development, which acquires a special meaning in context of lifelong learning. The purpose of this study is to analyse, how the creative activity of lecturers improves their own professional competences as well as influences and motivates the creative activity of students during the process of acquisition of textile course of studies. The following research methods have been applied: case study, survey (N=36). The study analyses the impact of creative activity of lecturers on study process in nine textile courses of studies, the choice of graduation paper subject and its d…
ID4 Is Required for Normal Ependymal Cell Development
2021
Ependymal cells are radial glia-derived multiciliated cells lining the lateral ventricles of the brain and spinal cord. Correct development and coordinated cilia beating is essential for proper cerebrospinal fluid (CSF) flow and neurogenesis modulation. Dysfunctions of ependymal cells were associated with transcription factor deregulation. Here we provide evidence that the transcriptional regulator ID4 is involved in ependymal cell development and maturation. We observed that Id4-deficient mice display altered ventricular cell cytoarchitecture, decreased ependymal cell number and enlarged ventricles. In addition, absence of ID4 during embryonic development resulted in decreased ependymal ce…
A Fair Share of Work: Is Fairness of Task Distribution a Mediator Between Transformational Leadership and Follower Emotional Exhaustion?
2019
Drawing on social resource theory and the norm of equity, this research proposes fairness of task distribution as a mediating mechanism of the well-established relationship between transformational leadership and followers’ well-being, conceptualizing the latter as low emotional exhaustion. Using data from 479 German employees in a three-wave longitudinal study, we found transformational leadership to be related to fair task distribution over time. The perceived fairness of task distribution mediated the relationship between transformational leadership and follower emotional exhaustion (structural equation modeling) when excluding stabilities. Our results also show a reverse causation effec…
Sonority as a Phonological Cue in Early Perception of Written Syllables in French
2020
Many studies focused on the letter and sound co-occurrences to account for the well-documented syllable-based effects in French in visual (pseudo)word processing. Although these language-specific statistical properties are crucial, recent data suggest that studies that go all-in on phonological and orthographic regularities may be misguided in interpreting how—and why—readers locate syllable boundaries and segment clusters. Indeed, syllable-based effects could depend on more abstract, universal phonological constraints that rule and govern how letter and sound occur and co-occur, and readers could be sensitive to sonority—a universal phonological element—for processing (pseudo)words. Here, …
