Aquiescence produce methods bias?: A study across self-esteem scales
2011
Un exercici corrent a les escales d’autoestima és presentar ítems en la direcció del tret, així com ítems en el sentit oposat. Aquesta pràctica ha esdevés habitual donat la presència d’aquiescència, entesa com la tendència a respondre de manera afirmativa amb independència del contingut dels ítems. Existeix abundant evidència a la literatura que el seu ús genera variància de mètode, fent aparéixer efectes de mètode no associats amb els trets d’interés. En aquest sentit, la present investigació pretén ampliar l’evidència i l’estudi de l’efecte de mètode associat als ítems negatius en el context de les escales d’autoestima. Es valora si aquest es presenta, no només quan l’autoestima es mesura…
Is individual- and school-level teacher burnout reduced by proactive strategies?
2021
There is provisional evidence that burnout may be contagious within professional communities via the crossover effect, referring to an inter-individual transmission of stress or strain. However, our understanding of effective means for tackling stressors is scarce. We tested a two-level path model to explore the interrelation between teachers’ proactive self- and co-regulative strategies and experienced burnout. The study sample comprised 1531 Finnish in-service teachers from 75 schools. The results showed that burnout symptoms varied both between individual teachers and between professional communities. Self- and co-regulative strategies serve partly different functions in regulating teach…
Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists
2018
The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…
Consensus nomenclature for CD8(+) T cell phenotypes in cancer
2015
International audience; Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T…

Omalizumab outcomes for up to 6 years in pediatric patients with severe persistent allergic asthma
2021
BACKGROUND: Various studies have assessed omalizumab outcomes in the clinical practice setting but follow-up and/or number of patients included were limited. We aim to describe the long-term outcomes of pediatric patients with severe persistent allergic asthma receiving omalizumab in the largest real-life cohort reported to date. METHODS: ANCHORS was a multicenter, observational, retrospective cohort study conducted in 25 Pediatric Allergy and Pulmonology units in Spain. We collected data of patients < 18 years and initiating omalizumab between 2006 and 2018, from the year prior to omalizumab initiation to discontinuation or last available follow-up. The primary outcome was the evolution of…
Inserimento di restringimenti e ponti in un modello diffusivo 2D di acque basse
2010
Gli effetti su una corrente, causati dalle pile di un ponte, o più in generale da strutture che riducono la sezione trasversale dell’alveo, risultano di particolare interesse per le variazioni idrometriche che comportano alla corrente stessa. Nonostante i numerosi studi teorici e sperimentali di letteratura, l’attuale modellistica numerica diffusiva non integra la presenza di tali manufatti nelle proprie tecniche risolutive. Nella presente memoria viene presentata la metodologia implementata nel modello diffusivo bidimensionale FLOW2D per la valutazione del rigurgito provocato da restringimenti della sezione trasversale, nonché dalla presenza delle campate. I profili di rigurgito ottenuti c…
Limits to Arbitrage and Interest Rates: a Debate Between Keynes, Hawtrey and Hicks
2018
International audience; This paper deals with a debate between Hawtrey, Hicks and Keynes concerning the capacity of the central bank to influence the short-term and the long-term rates of interest. Both Hawtrey and Keynes considered the central bank’s ability to influence short-term rates of interest. However, they do not put the same emphasis on the study of the long-term rates of interest. According to Keynes, long-term rates are influenced by future expected short-term rates (1930, 1936), whereas for Hawtrey (1932, 1937, 1938), long-term rates are more dependent on the business cycle. Short-term rates do not have much effect on long-term rates according to Hawtrey. In 1939, Hicks enters …
Dual action of phosphonate herbicides in plants affected by herbivore—Model study on black bean aphid Aphis fabae rearing on broad bean Vicia faba pl…
2008
Abstract The interactions between plants, herbicides and herbivore insects were studied as an aspect of possible side effect of the using of phosphonate herbicides. The experimental system was composed of phosphonate herbicides, broad bean Vicia faba (L.) plants and black bean aphid Aphis fabae (Scopoli). Two means of herbicide application, namely standard spraying and direct introduction of the herbicide into stem via glass capillary, were examined. The results obtained for N-2-piridylaminomethylene bisphosphonic acid and its derivatives show 10 times higher inhibition of the plant growth if glass capillary mode was used. When plants were infested by aphids 24 h after the use of herbicide,…
Gender Differences in the Frequency of Positive and Negative Effects after Acute Caffeine Consumption
2023
Gender-specific caffeine-related adverse effects should be thoroughly investigated. Sixty-five adult participants were included in the study, 30 men and 35 women (age, 22.5 ± 2.8; body weight, 71.7 ± 16.2 kg; BMI, 23.6 ± 4.4). The participants who were classified as low and moderate caffeine users received 3 mg/kg, and high caffeine users received 6 mg/kg of caffeine in one dose. One hour after ingestion of caffeine and within twenty-four hours, the participants completed a side effect questionnaire. Effects after the ingestion of CAF were divided into two subgroups: negative (muscle soreness, increased urine output, tachycardia and palpitations, anxiety or nervousness,…
