Abstract

The post - fire investigation is conducted on a fire-affected reinforced concrete shear wall building to ascertain the level of its strength degradation due to the fire incident. Fire incident took place in a three-storey building made of reinforced concrete shear wall and roof with operating floors made of steel beams and chequered plates. The usage of the building is to handle explosives. Elevated temperature during the fire is estimated to be 3500C based on visual inspection. Destructive (core extraction) and non-destructive (rebound hammer and ultrasonic pulse velocity) tests are conducted to evaluate the concrete strength. X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) are used for analyzing micro structural changes of the concrete due to fire. Tests are conducted for concrete walls and roof slab on both burnt and unburnt locations. The analysis of test results reveals no significant degradation of the building after the fire which signifies that the structure can be used with full expectancy of performance for the remaining service life. This document can be used as a reference for future forensic investigations of similar fire affected concrete structures.

2. Third Party Reports influence parents’ perceptions of coaching ability: Implications for youth sport coaches

Abstract

According to Olson, Roese, and Zanna’s (1996) Model of Expectancy Processes, information conveyed by others can determine our expectancies of people. Furthermore, Third Party Reports (TPRs) such as reputation may influence athletes’ initial expectancies of coaches (e.g., Manley et al., 2008; 2010; Thelwell et al., 2013). Parents are believed to play a fundamental role in the development of coach-athlete relationships (e.g., Jowett & Katchis, 2005) and, in turn, athletic achievement in youth sport (Gould et al., 2008). However, person perception research has not yet examined the impact of cues such as TPRs on the initial impressions and expectancies that parents form of youth sport coaches. The current study addresses this gap in the literature. Athletes’ parents viewed a hypothetical online report describing the appointment of a new coach at a local sports club. The report included a “comments” section, which consisted of “tweets” posted by the newly-appointed coach’s former athletes. Four experimental conditions were created by manipulating the coach’s level of warmth and competence (i.e., high vs. low) as reported through the “comments/tweets” (i.e., TPRs). After reading the online report, participants provided ratings of the coach’s ability using the Coaching Competency Questionnaire (Myers et al., 2006). Participants are currently being recruited via gatekeepers at sports clubs/organisations, as well as through social media. However, based on an initial sample (n = 83), Kruskal-Wallis tests typically revealed that high-warmth/high-competence TPRs resulted in highest evaluations of overall coaching ability, while TPRs low in both warmth and competence received poorest ratings. Interestingly, perceptions of Character-building Competence were highest for high-warmth/low-competence TPRs. These preliminary findings reveal that TPRs can influence parents’ perceptions of coaching proficiency, but that parents may value warmth over competence when assessing a coach’s ability to develop more holistic qualities in youth sport athletes.

Abstract

Aldosterone excess can produce heart and kidney fibrosis, which seem to be related to a direct effect of aldosterone at the level of specific receptors. We report a direct, mineralocorticoid-mediated effect on the protein expression of two markers of oxidative stress after incubation of mononuclear leukocytes with 1 × 10−8m aldosterone (p22phox/β-actin = 1.38 ± 0.05 and PAI-1/β-actin = 1.80 ± 0.05). The same effect was also found with 3 × 10−5m glycyrrhetinic acid, the principal constituent of licorice root (p22phox/β-actin = 1.37 ± 0.97 and PAI-1/β-actin = 1.80 ± 0.04). The effect of both aldosterone and glycyrrhetinic acid is blocked by incubation with added 1 × 10−6m of receptor-antagonist canrenone. Canrenone alone did not show any effect. PAI-1 related protein was also found using 4 × 10−9m aldosterone. Incubations with 1 × 10−9m for 3 hours as well as 1 × 10−8m aldosterone for 5, 10, and 20 minutes were ineffective for both proteins. These data support the previous finding of an involvement of mononuclear leukocytes in the pathogenesis of the oxidative stress induced by hyperaldosteronism. In addition, the results confirm our previous data on a direct effect of glycyrrhetinic acid at the level of mineralocorticoid receptors.
