Technical, tactical and spatial indicators related to goal scoring in European elite soccer
No full textThe aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, or actions as dribbling or running with the ball had a greater percentage of goals against circumstantial defences (2=37.027; p>0.001). Besides, greater utilization of wide invasive spaces (70.2%) was observed to assist against organized defences, while this percentage was 53.1% (2=5.501; p=0.015) against circumstantial defences. For the last action, 70.1% of the goals were scored by using only one contact to the ball in organized defences but 46.6% in circumstantial defences (2=26.521; p>0.001). The technical and tactical actions that achieve goal and their spatial characteristics are related to the type of defence used by the opposing tea
Effectiveness and duration of plantar pressure offloading by two designs of felt padding: a preliminary study
No full textBackground: The aim of this study was to observe the pressure changes in the felt padding used to off-load pressure from the first metatarsal head, the effects obtained by different designs, and the loss of effectiveness over time. Method: With a study population of 17 persons, two types of 5-mm semicompressed felt padding were tested: one was C-shaped, with an aperture cutout at the first metatarsophalangeal joint, and the other was U-shaped. Pressures on the sole of the foot were evaluated with a platform pressure measurement system at three time points: before fitting the felt padding, immediately afterward, and 3 days later. Results: In terms of decreased mean pressure on the first metatarsal, significant differences were obtained in all of the participants (P , .001). For plantar pressures on the central metatarsals, the differences between all states and time points were significant for the C-shaped padding in both feet (P , .001), but with the U-shaped padding the only significant differences were between no padding and padding and at day 3 (P ¼ .01 and P ¼ .02). Conclusions: In healthy individuals, the U-shaped design, with a padding thickness of 5 mm, achieved a more effective and longer-lasting reduction in plantar pressure than the C-shaped design
Cotinine administration improves impaired cognition in the mouse model of Fragile X syndrome
No full textCotinine is the major metabolite of nicotine and has displayed some capacity for improving cognition in mouse models following chronic administration. We tested if acute cotinine treatment is capable of improving cognition in the mouse model of Fragile X syndrome, Fmr1-/- knockout mice, and if this is related to inhibition by cotinine treatment of glycogen synthase kinase-3β (GSK3β), which is abnormally active in Fmr1-/- mice. Acute cotinine treatment increased the inhibitory serine-phosphorylation of GSK3β and the activating phosphorylation of AKT, which can mediate serine-phosphorylation of GSK3β, in both wild-type and Fmr1-/- mouse hippocampus. Acute cotinine treatment improved cognitive functions of Fmr1-/- mice in coordinate and categorical spatial processing, novel object recognition, and temporal ordering. However, cotinine failed to restore impaired cognition in GSK3β knockin mice, in which a serine9-to-alanine9 mutation blocks the inhibitory serine phosphorylation of GSK3β, causing GSK3β to be hyperactive. These results indicate that acute cotinine treatment effectively repairs impairments of these four cognitive tasks in Fmr1-/- mice, and suggest that this cognition-enhancing effect of cotinine is linked to its induction of inhibitory serine-phosphorylation of GSK3. Taken together, these results show that nicotinic receptor agonists can act as cognitive enhancers in a mouse model of Fragile X syndrome and highlight the potential role of inhibiting GSK3β in mediating the beneficial effects of cotinine on memory
Methylammonium-free, high-performance, and stable perovskite solar cells on a planar architecture
No full textCurrently, perovskite solar cells (PSCs) with high performances greater than 20% contain bromine (Br), causing a suboptimal bandgap, and the thermally unstable methylammonium (MA) molecule. Avoiding Br and especially MA can therefore result in more optimal bandgaps and stable perovskites. We show that inorganic cation tuning, using rubidium and cesium, enables highly crystalline formamidinium-based perovskites without Br or MA. On a conventional, planar device architecture, using polymeric interlayers at the electron- and hole-transporting interface, we demonstrate an efficiency of 20.35% (stabilized), one of the highest for MA-free perovskites, with a drastically improved stability reached without the stabilizing influence of mesoporous interlayers. The perovskite is not heated beyond 100°C. Going MA-free is a new direction for perovskites that are inherently stable and compatible with tandems or flexible substrates, which are the main routes commercializing PSCs
Des dels segons plans. Estudi de l'assaig de Josep Igual
No full textA partir d'una tria de set llibres de Josep Igual, ens proposem caracteritzar la seua escriptura assagística, tenint en compte cinc paràmetres d'anàlisi: l'escriptura en prosa, el pacte autobiogràfic, el predomini de l'argumentació, l'ús dels paratextos i la funció social. Com podrem constatar, tots els llibres presenten els elements clàssics d'aquest gènere literari, amb l'excepció parcial de Plàncton. A més a més, es tracta d'obres que procedeixen del seu dietari, cosa que ens permetrà plantejar algunes hipòtesis sobre la importància d'aquesta escriptura -en principi privada- en l'obra de Josep Igual i, per extensió, en la tradició de l'assaig. Finalment, dedicarem una certa atenció a la importància del territori i d'altres referents culturals en l'autor de Benicarló
La disrupció de la veu d'Alda Merini en la poesia catalana actual
No full textLa investigació que proposem s'incorpora a la tendència dels últims anys dels estudis poètics i traductològics dedicada a recuperar les obres capitals de dones que han estat silenciades i marginades del cànon en funció de criteris, quasi sempre, extraliteraris. Una autora com Alda Merini, candidata al Nobel, fins fa ben poc temps era una desconeguda per al públic en català i, de fet, el seu llibre més destacable, La Terra Santa, no havia estat traduït mai. L'any 2016 aparegueren dues traduccions importants de la seua obra La clínica de l'abandó i La Terra Santa , que, molt parcialment, corregeixen aquest deute. La recuperació actual de l'obra de Merini per mitjà de traduccions forma part d'una tasca necessària de visibilització de les genealogies poètiques, amb les implicacions posteriors de revisió del cànon literari
A short version of the Alcohol Consumption Consequences Evaluation Scale (ACCE10)
No full textA brief version of the Alcohol Consumption Consequences Evaluation Scale (ACCE) [38] was developed to promptly detect possible risks related to alcohol consumption, such as Binge Drinking (BD), in university students. Using the 'snowball' method, a sample of 595 students aged 18 to 20 (65.4% women) from the University of Valencia (Spain) was obtained during the 2019-2020 academic year. Items with the highest values of the discrimination parameter in the original version (ACCE) were selected and the Rasch model was applied. To verify the usefulness of this version, ROC analyses were conducted separately for men and women using the Audit score as the criterion. In the overall sample, the analysis had an area of 0.812 (SE = 0.018). In men, the area was 0.796 (SE = 0.032) and for women, it was 0.823 (SE = 0.021). In addition, a logistic regression analysis was performed, using a cut-off point of 3 based on the ROC analysis, to assess the utility of this version in classifying BD and non-BD. The odds ratio was 3.812 (p = 0.000), correctly classifying 89.2% of the young people and indicating that the probability of engaging in BD is 3.8 times higher for individuals obtaining more than 3 points on this scale. This result confirms the usefulness of this brief version (ACCE10) as a screening tool for early intervention, especially in clinical or university settings, since it allows young people to be situated within a range of severity according to their consumption patterns. Furthermore, it may help stop the progression of the addictive process, create awareness of the need for change, and facilitate access to the most suitable interventions
Impaired recollection and initially preserved familiarity in a patient with bilateral fornix transection following third ventricle colloid cyst removal: A two-year follow-up study
No full textObjective Recognition memory is widely accepted as a dual process-based model, namely familiarity and recollection. However, the location of their specific neurobiological substrates remains unclear. Similar to hippocampal damage, fornix damage has been associated with recollection memory but not familiarity memory deficits. To understand the neural basis of recognition memory, determining the importance of the fornix and its hippocampal connections is essential. Methods Recognition memory was examined in a 45-year-old male who underwent a complete bilateral fornix section following the removal of a third ventricle colloid cyst. The application of familiarity and recollection for recognition memory decisions was investigated via an immediate and delayed associative recognition test and an immediate and delayed forced-choice task in the patient and a control group (N = 15) over a two-year follow-up period. Complete demographic, neuropsychological, neuropsychiatric, and neuroradiological characterizations of this patient were performed. Results Persistent immediate and delayed verbal recollection memory deficits were observed in the patient. Moreover, delayed familiarity-based recognition memory declined gradually over the follow-up period, immediate familiarity-based recognition memory was unaffected, and reduced non-verbal memory improved. Conclusion The present findings support models that the extended hippocampal system, including the fornices, does not appear to play a role in familiarity memory but is particularly important for recollection memory. Moreover, our study suggests that bilateral fornix transection may be associated with relatively functional recovery of non-verbal memor
Bibliometric analysis of Emotion-Focused Therapy: a psychotherapeutic orientation in scientific flourishing
No full textEmotion-Focused Therapy (EFT) is an empirically supported humanistic treatment that considers clients' emotional processes as the path to therapeutic change. The present aim was to develop a bibliometric study of EFT articles published in the Web of Science (WoS) Core Collection. Books and chapters were not included in this research. The bibliometric analysis was performed using Hiscite and VosViewer. Results showed 273 publications on EFT in WoS, the first being in 1994. The most relevant areas were depression and anxiety. The most productive author is Greenberg (n = 56; GCS = 2050). The 51.28% of publications corresponds to the last five years (2016-2020), observing a substantial increase in publications comparing with previous years. It is concluded that EFT is a psychotherapeutic orientation in recent scientific growth, with potential interest for further development in next years. The absence of results in WoS prior to 1994 is a limitation, given the origins of EFT in the 1970s. Extension of this study is recommended, including: publications about emotionally focused therapy, publications from other databases different from WoS, together with books and chapters. The importance of these results is discussed to allow other researchers and professionals to know deeply about the scientific production in EFT and its impact
Orígenes y evolución de las cooperativas de crédito hasta su equiparación como entidades de crédito
No full textEste artículo examina la evolución histórica y jurídica de las cooperativas de crédito, desde sus orígenes en el siglo XIX hasta su consolidación como entidades de crédito equiparadas a las instituciones financieras convencionales. A través de un análisis detallado, se identifican tres etapas clave en su desarrollo: la distinción inicial de las cooperativas respecto a las sociedades mercantiles y sindicatos; la formalización del cooperativismo de crédito durante el régimen franquista; y finalmente, la equiparación con las entidades de crédito en la España democrática, destacando la Ley 13/1989 que estableció un marco jurídico unificado para estas instituciones. Además, se discute la naturaleza jurídica de las cooperativas de crédito, situándolas como entidades sui generis dentro del derecho cooperativo y financiero, y se evalúan las implicaciones de su evolución normativa en el contexto del sistema financiero español
