Use of Rounded Base Turns in General Aviation Traffic Patterns: A Quantitative Analysis

Prevention of in-flight loss of control (I-LOC) in General Aviation (GA) continues to be identified as a most-wanted safety improvement by the National Transportation Safety Board (NTSB), with emphasis on low-altitude maneuvering. A possible technique to mitigate I-LOC is modification of the rectangular traffic pattern used by aircraft arriving and maneuvering within the airspace around an airport. The rectangular pattern is used to align the aircraft with the runway for landing and consists of a “base leg” in which two 90-degree directional changes are accomplished. A “rounded-base” could instead be conducted, consisting of a constant 180- degree turn, potentially resulting in lower angles-of-attack (AOA), thereby keeping the aircraft further from the critical AOA at which I-LOC may occur. Using flight data monitoring equipment, a comparative statistical analysis was conducted between the rectangular method and rounded base method to evaluate variables that influence AOA and determine if the rounded-base method provides an increased level of safety. Results suggest that the rounded base method does allow for lower bank angles, lower pitch attitudes, lower vertical speeds, and more consistent indicated airspeeds throughout the maneuver. Additionally, the rounded-base method considerably reduces the likelihood of runway overshoot during the turn to final

Technical and Regulatory Factors of Adopting Electric Training Aircraft in a Collegiate Aviation Setting

Electric-powered aircraft have entered the market. The arrival of the Pipistrel Velis Electro and other developmental efforts by companies such as Bye Aerospace, Piper, and eViation, have signaled to the aviation community that more electric-powered aircraft can be expected in the coming years. But how useful are they for training pilots in a Federal Aviation Administration (FAA) approved Part 141 collegiate aviation environment? To identify candidate flight courses and lessons, the authors examine flight hour distributions of a one-year window of invoiced flights (N = 52,728), including flight hour data cut-points at 60 minutes (n = 6,050) and 90 minutes (n = 25,439). The data distribution suggests that approximately 11.5% of the candidate flights would fall within a 60-minute expected flight duration, whereas 48% of flights would fall within a 90-minute flight duration. These calculations provide realistic targets for designed minimum flight duration (plus the inclusion of required FAA reserve) in order to be determined a feasible trainer in many high-volume FAA Part 141 training environments. Detailed course-level analysis suggests the Instrument Flight Instructor (CFII) flight course as a potential launch point for electric flight due to the relatively lower flight hour per lesson. In addition to minimum flight duration, other feasibility questions are included in this analysis, such as regulatory requirements, battery duration, aircraft turnaround time, multiple charge-discharge cycles per day, environmental factors, airport charging infrastructure, and maintenance factors. Additional research will benefit this developing area of electric aircraft in flight training environments

Bone Morphogenetic Protein-9 Is a Potent Chondrogenic and Morphogenic Factor for Articular Cartilage Chondroprogenitors

Articular cartilage contains a subpopulation of tissue-specific progenitors that are an ideal cell type for cell therapies and generating neo-cartilage for tissue engineering applications. However, it is unclear whether the standard chondrogenic medium employing transforming growth factor-β (TGFβ) isoforms is optimal to differentiate these cells. We therefore used pellet culture to screen progenitors from immature bovine articular cartilage with a number of chondrogenic factors and discovered that bone morphogenetic factor-9 (BMP9) precociously induces their differentiation. This difference was apparent with toluidine blue staining and confirmed by biochemical and transcriptional analyses with BMP9 treated progenitors exhibiting 11-fold and 5-fold greater aggrecan and collagen type II gene expression than TGFβ1 treated progenitors. Quantitative gene expression analysis over 14 days highlighted the rapid and phased nature of BMP9 induced chondrogenesis with sequential activation of aggrecan then collagen type II, and negligible collagen type X gene expression. The extracellular matrix of TGFβ1treated progenitors analysed using atomic force microscopy was fibrillar and stiff whist BMP9-induced matrix of cells more compliant and correspondingly less fibrillar. Polarised light microscopy revealed an annular pattern of collagen fibril deposition typified by TGFβ1 treated pellets, whereas BMP9 treated pellets displayed a birefringence pattern that was more anisotropic. Remarkably, differentiated immature chondrocytes incubated as high-density cultures in vitro with BMP9 generated a pronounced anisotropic organisation of collagen fibrils indistinguishable from mature adult articular cartilage, with cells in deeper zones arranged in columnar fashion. This contrasted with cells grown with TGFβ1 where a concentric pattern of collagen fibrils was visualised within tissue pellets. In summary, BMP9 is a potent chondrogenic factor for articular cartilage progenitors and is also capable of inducing morphogenesis of adult-like cartilage, a highly desirable attribute for in vitro tissue-engineered cartilage

Paediatric distal radial fracture manipulation: Multicentre analysis of process times

Background: Children with simple radial fractures requiring manipulation are conventionally admitted for manipulation under general anaesthesia. On the assumption that children (and their parents) wish to spend as little time in hospital as possible, a study was undertaken to explore the experience of children with distal radial fractures admitted for general anaesthesia. Methods: A retrospective analysis was performed of the time taken from arrival at the emergency department (ED) to general anaesthesia and the time taken from arrival at the ED to hospital discharge in three centres in south-west England: the Bristol Children's Hospital, Derriford (Plymouth) Hospital and the Royal Devon & Exeter Hospital. Results: The median wait for general anaesthesia was >8 h and the median wait from ED admission to discharge was >21 h. This compares with a typical arrival to discharge time for paediatric procedural sedation of 4-5 h in the ED of the Royal Devon & Exeter Hospital. Conclusions: Given the assumption that children (and their parents) wish to spend as little time in hospital as possible, there appears to be a role for procedural sedation in the ED for this group of children, with a significantly reduced turnaround time anticipated

Perception of academic learning environments and perceived impact on articulation of employability; a mixed methods study

This study reports on the findings of a mixed methods study that was undertaken to establish student perceptions of academic learning environments and the perceived impact of these on their articulation of employability skills. This was so student perspectives on employability could be used to inform reflection on pedagogic practices for their educators in higher education. Using a purposive sample of 250 students based in a recently modernised Sciences Complex Building in a Higher Education Institution (HEI), the study was cross sectional and descriptive by design. The social learning spaces researched were perceived by participants to provide optimal academic learning environments for their development of knowledge, skills and professionalism through certain signature pedagogies as they progressed through their programmes of study. Students also expressed the view that their acquisition of functional skills were significantly more important than any personal attributes/characteristics that they brought to programmes. What also mattered was whether the importance of certain graduate skills to the workplace had been made explicit to them so that they could see the relevance of their studies to practice. In defining ‘graduateness’, in employability terms the research Hayes et al. Perception of academic learning environments and perceived impact on articulation of employability skills Journal of Learning Development in Higher Education, Issue 10: November 2016 2 concluded that it was necessary to consider how it was shaped by the context of delivery of subject disciplines, stages of academic progression, and the use of social learning spaces, as they all had a significant impact on the perceptions students held about their potential employability upon completion of their academic programmes. Keywords: learning environments; employability; signature pedagogies; situated cognition; problem based learning

Against Reduction

Provocative, hopeful essays imagine a future that is not reduced to algorithms. What is human flourishing in an age of machine intelligence, when many claim that the world's most complex problems can be reduced to narrow technical questions? Does more computing make us more intelligent, or simply more computationally powerful? We need not always resist reduction; our ability to simplify helps us interpret complicated situations. The trick is to know when and how to do so. Against Reduction offers a collection of provocative and illuminating essays that consider different ways of recognizing and addressing the reduction in our approach to artificial intelligence, and ultimately to ourselves. Inspired by a widely read manifesto by Joi Ito that called for embracing the diversity and irreducibility of the world, these essays offer persuasive and compelling variations on resisting reduction. Among other things, the writers draw on Indigenous epistemology to argue for an extended “circle of relationships” that includes the nonhuman and robotic; cast “Snow White” as a tale of AI featuring a smart mirror; point out the cisnormativity of security protocol algorithms; map the interconnecting networks of so-called noncommunicable disease; and consider the limits of moral mathematics. Taken together, they show that we should push back against some of the reduction around us and do whatever is in our power to work toward broader solutions

Institutions and social structures

This paper clarifies the terms "institutions" and "social structures" and related terms "rules", "conventions", "norms", "values" and "customs". Part one explores the similarities between institutions and social structures whilst the second and third parts explore differences. Part two considers institutions, rules, habits or habitus and habituation, whilst part three critically reflects on three common conceptions of social structures. The conclusion comments upon reflexive deliberation via the internal conversation. © The Executive Management Committee/Blackwell Publishing Ltd. 2008

Quantifying the impact of social mobilisation in rural Bangladesh : donors, civil society and 'the road not taken'

As part of a general trend toward a reduced role for the state, international donors have increasingly encouraged development NGOs to take up a service delivery function. In Bangladesh, this has induced NGOs to shift their core activities away from social mobilisation to a focus on providing microfinance services, although many organisations also promote education, health and other social services. NGOs are credited with some of Bangladesh’s remarkable progress on poverty reduction, human development indicators and the Millennium Development Goals. However, social inequalities persist, and the quality of governance is extremely low. This paper reports on the impact of an NGO, Nijera Kori (NK), in rural Bangladesh on its members’ democratic knowledge, practice and engagement. Unique among its peers, NK’s work with the landless poor prioritises rights, social mobilisation and solidarity over more individualistic forms of democratic participation. The study carried out a survey of randomly selected members of NK, along with a randomly selected ‘control group’ from the same socioeconomic background of the NK membership. Statistical analysis of the data confirms much higher levels of political awareness and participation among NK members. More surprisingly, given that NK does not distribute microfinance, NK membership was also associated with a number of material impacts, including more diverse household diets, a higher likelihood of asset ownership and higher levels of economic activity relative to non-members. Levels of ‘trust’ in local power structures and public institutions were significantly lower amongst NK members compared to nonmembers, challenging some of the dominant assumptions about the positive correlation between social trust and political participation. We propose that NK’s intensive focus on education, information-sharing and social mobilisation instils a level of political consciousness in members that qualifies trust in public institutions, with implications for enhanced democratic accountability and an alternative civil society approach to improving democratic citizenship.

Self-reported psychopathy and aggression motivation: A role for emotions?

The current study examined the psychopathy-aggression relationship by considering different forms of aggression, including aggressive motivation. Emotions were explored as useful in understanding any emerging relationship, notably those consistent with detachment and sensitivity/poor regulation. In three studies, involving non-offending samples (Study one: n = 150, 47 men, 103 women; Study two: n = 442, 314 men, 123 women, five not disclosed; Study three: n = 200, 100 men and 100 women), it was predicted that higher levels of psychopathy would be associated with reports of higher overall, proactive and reactive aggression, and that the association would be moderated by emotion. Specifically, it was predicted that emotion regulation difficulties would associate with higher levels of reactive but not proactive aggression, and that proactive aggression would involve a lack of emotion. Findings generally supported the predictions. The role of emotion-regulation difficulties as a mediator between psychopathy and reactive aggression, and greater emotional detachment as a mediator between psychopathy and proactive aggression was demonstrated. The results demonstrate importance for the components of psychopathy and different aspects of emotion for the psychopathy-aggression link. Directions for future research and some implications for practice are outlined
