Effect of Stacking Sequence and Sodium Bicarbonate Treatment on Quasi-Static and Dynamic Mechanical Properties of Flax/Jute Epoxy-Based Composites

2019

The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed …

Mocking fakeness

2022

Abstract Phonetic resources, like dialects and accents, are used in ethnic humour to build up a recognisable character that pokes fun at the stereotypes associated with a particular identity, sometimes with critical and political undertones. In this article, we examine the manipulation of one such resource, aspiration, used in performing and mocking one such clichéd character, called the fake Sámi. This character has a contested history in Finnish tourism and marketing practices, and is embedded in a long-standing debate about who can use emblems of Sámi identity for economic purposes. Adopting a sociophonetic language regard and folk linguistics approaches (Preston 2010; Niedzielski & …

High testosterone levels and sensitivity to acute stress in perpetrators of domestic violence with low cognitive flexibility and impairments in their…

2013

Hormonal and neuropsychological impairment in intimate partner violence (IPV) perpetrators could play a role in domestic violence. For characterizing whether there is a specific psychobiological response to stress, participants who had previously been jailed for IPV and controls were compared for testosterone and cortisol levels, tested for 2D:4D ratio (as an indicator of masculinization), and given several trait questionnaires and neuropsychological tests related to executive functions and theory of mind. After performing the Trier Social Stress Test (TSST), IPV perpetrators experienced decreases in salivary testosterone (T) levels, a moderate worsening of mood, slight anxiety, and a saliv…

Emisores políticos, mediáticos y ciudadanos en internet: hacia un nuevo marco comunicativo en la jornada de reflexión en España

2015

Resumen La campaña electoral en España está regulada por la ley orgánica de régimen electoral general 5/1985, que no contempla ninguna medida específica para la cibercampaña. Este vacío legal motiva a los emisores a realizar una interpretación de la norma cuando se comunican en internet durante este periodo. Con el fin de explorar si el nuevo tempo y forma de comunicación en internet se corresponde con un nuevo espacio comunicativo, este estudio analiza los mensajes que políticos, periodistas y ciudadanos se intercambiaron en la jornada de reflexión de las últimas elecciones generales españolas (2011) y muestra cómo esta jornada, comprendida hasta la fecha como un día de reflexión silencios…

Is it true that young drama practitioners are more creative and have a higher emotional intelligence?

2021

Abstract Drama studies can provide adolescents and young adults with learning opportunities that can help them to develop creative and socio-emotional skills. In interviews and discussion groups, when given the opportunity to talk about their experiences, young drama students explain the creative and emotional benefits they feel they have received from their participation in the arts. This research study investigates whether engagement, and particularly engagement over time, in drama is significant in stimulating creative and socio-emotionally intelligent behaviour in young people. It compares the creative and socio-emotional levels of adolescents and young adults who participate in drama s…

Individual differences in behavioral consistency are related to sequential access to resources and body condition in a producer-scrounger game

2014

Investigating the evolution of consistent between-individual behavioral differences necessitates to explain the emergence of within-individual consistency. Relying on a recent mathematical model, we here test the prediction that the emergence of differences in within-individual consistency is related to the sequential access to resources in a frequency-dependent foraging game. To this end we used flocks of zebra finches (Taeniopygia guttata) engaged in a producer-scrounger foraging game. Tactic investment (i.e., the proportion of hops with the head down) significantly predicted successful tactic use (i.e., the proportion of seeds produced). In support of predictions, we found that individua…

Representational flexibility in children's drawings: Effects of age and verbal instructions

1999

This study aims to investigate representational and syntactical flexibility in children's drawing behaviour, and the extent to which changes introduced at both representational and syntactical levels are related to age or can be induced by contextual manipulations. A Deletion task required three age groups of 5-, 7- and 9-year-old children to draw objects that had been rendered partially invisible, thanks to magic transformations. Two different verbal instructions about what was to remain visible in the objects, and two different objects, one regularly and one non-regularly drawn, were designed to investigate contextual sensitivity in children's representational and syntactical behaviour re…

Reading and Writing Skills in Adolescents With Autism Spectrum Disorder Without Intellectual Disability.

2021

The purpose of this study is to extend the knowledge about academic achievement in individuals with autism spectrum disorder (ASD). To this end, first, we analyzed differences in a wide range of reading and writing skills in adolescents with ASD without intellectual disability (ASD-WID) and adolescents with typical development (TD). Second, these two groups were compared on academic outcomes in core subjects and indicators of successful transition to secondary school. Third, the potential contribution of literacy skills to academic outcomes was examined in the two groups. Participants were 56 adolescents between 12 and 14 years old, 30 with ASD-WID and 26 with TD. Results showed no signific…

2019

Ankle plantar flexor muscles are active in the stance phase of walking to propel the body forward. Increasing walking speed requires increased plantar flexor excitation, frequently assessed using surface electromyography (EMG). Despite its popularity, validity of surface EMG applied on shank muscles is mostly unclear. Thus, we examined the agreement between surface and intramuscular EMG at a range of walking speeds. Ten participants walked overground at slow, preferred, fast, and maximum walking speeds (1.01 ± 0.13, 1.43 ± 0.19, 1.84 ± 0.23, and 2.20 ± 0.38 m s-1, respectively) while surface and fine-wire EMG activities of flexor hallucis longus (FHL), soleus (SOL), medial gastrocnemius (MG…

Effect of footwear on plantar flexor fine-wire electromyography activity in walking

2019

Compared to barefoot walking, walking in footwear seems to alter plantar flexor electromyography (EMG) activity, vertical and horizontal ground reaction forces (Sacco, Akashi, & Hennig, 2010), ankle kinematics and the time of peak activity (Sacco et al., 2010). However, study results are inconsistent regarding the magnitude and direction of these changes. Magnetic resonance imaging showed high inter-individual variability in muscle metabolic activity during walking, suggesting individual-specific activation patterns (Kolk et al., 2015). Additionally, little is known about the role of toe flexors such as flexor hallucis longus (FHL) in walking.
