Contemporary debates on the transformation of building methods, the structure of the building industry, and the introduction of new technologies (informational, material and structural) in professional literature and in the architectural humanities tend to ignore the realities of work on construction sites. This follows a long history of failure to recognise the importance of workers’ experience and knowledge of building as a process by the key professions in the industry. The absence of the working process in accounts of historical development is exacerbated by abstract reflection on building know-how, categories of expertise, and the structure of the industry, when these are not supported by direct observation and engagement with building work and workers. Key assumptions about the relation between structural and technological changes in the industry and the knowledge, skills, composition, and requirements of the workforce can be challenged by paying attention to day-to-day activities and conditions of site work

Understanding Transgender Prejudice Through the Lens of Emotion

Transgender individuals report facing incidents of discrimination often in all aspects of their lives (James et al., 2016). A potential way to combat the discrimination transgender people face is through reducing transgender prejudice. However, it is not yet known what comprises transgender prejudice. Some research has found that emotions may be the more predominant determinant of prejudice, as opposed to stereotypes (Dasgupta, Desteno, Williams, & Hunsinger, 2009; Haddock, Zanna, & Esses, 1993a; Smith, 1993). Thus, the present research sought to identify the specific emotions associated with transgender prejudice. In Study 1, participants completed explicit and implicit measures of prejudice and measures of basic emotions (e.g., anger, disgust) about transgender men and women. In Study 2, participants completed an online survey of self-reported prejudice and emotions (both primary and secondary) toward transgender men and women. The studies found that more disgust, anger and contempt toward transgender individuals was associated with more prejudice; and more compassion toward transgender individuals was associated with less prejudice. Additionally, the studies found that differential patterns of emotions were associated with transgender individuals compared to cisgender individuals. Overall, the studies provide support that differential emotions are related to transgender prejudice

Formalisation and Implementation of the XACML Access Control Mechanism

We propose a formal account of XACML, an OASIS standard adhering to the Policy Based Access Control model for the specifica- tion and enforcement of access control policies. To clarify all ambiguous and intricate aspects of XACML, we provide it with a more manageable alternative syntax and with a solid semantic ground. This lays the basis for developing tools and methodologies which allow software engineers to easily and precisely regulate access to resources using policies. To demonstrate feasibility and effectiveness of our approach, we provide a software tool, supporting the specification and evaluation of policies and access requests, whose implementation fully relies on our formal development

The pharmacokinetics of nebulized nanocrystal budesonide suspension in healthy volunteers.

Nanocrystal budesonide (nanobudesonide) is a suspension for nebulization in patients with steroid-responsive pulmonary diseases such as asthma. The pharmacokinetics and safety of the product were compared to those of Pulmicort Respules. Sixteen healthy volunteers were administered nanobudesonide 0.5 and 1.0 mg, Pulmicort Respules 0.5 mg, and placebo in a four-way, randomized crossover design. All nebulized formulations were well tolerated, with no evidence of bronchospasm. Nebulization times were significantly shorter for nanobudesonide compared to Pulmicort Respules. Because of a low oral bioavailability, plasma concentration of budesonide is a good marker of lung-delivered dose. The pharmacokinetics of nanobudesonide 0.5 and 1.0 mg were approximately dose proportional with respect to Cmax, AUC(0-t), and AUC(0-infinity). Nanobudesonide 0.5 mg and Pulmicort Respules 0.5 mg exhibited similar AUCs, suggesting a similar extent of pulmonary absorption. A higher Cmax was noted with nanobudesonide 0.5 mg, and the tmax was significantly different, suggesting a more rapid rate of drug delivery of nanobudesonide 0.5 mg than Pulmicort Respules. In conclusion, nebulized nanobudesonide 0.5 mg was safe in healthy volunteers, with a similar extent of absorption as Pulmicort Respules

Establishment Techniques to Increase the Production of Italian Ryegrass (\u3cem\u3eLolium multiflorum\u3c/em\u3e) Over-Sown into an Irrigated Kikuyu (\u3cem\u3ePennisetum clandestinum\u3c/em\u3e) Pasture

Irrigated mixed pastures of kikuyu (Pennisetum clandestinum) over-sown with Italian ryegrass (Lolium multiflorum) in the cool-season (May-October) can produce large amounts of biomass in a sub-tropical environment (Botha et al. 2008). However, appropriate pasture management practices are required to suppress the aggressive growth of kikuyu prior to autumn, in order to facilitate establishment of ryegrass seedlings. The present study evaluated ryegrass establishment techniques on the dry matter (DM) production, botanical composition and forage quality of a mixed sward containing kikuyu
