Understanding professional community and professional identity through the experiences of Bahraini teachers working with British teachers in a partnership project

This paper is an exploration into the nature of the professional community that is formed when teachers from different nations work together. The research presented here consists of the findings from a small-scale exploratory case study that is the scoping study for a larger piece of research on this same theme. This larger piece of research is my doctoral study that I am currently undertaking at Cambridge University. This paper specifically involves the presentation of data drawn from interviews with teachers from Bahrain who have been involved in working with teachers from Britain via programmes run by the British Council and others. In this paper I discuss how identity is constructed within a professional community that crosses national boundaries. I conclude by suggesting that teachers who are working with colleagues from other nations build their professional identity together in innovative and exploratory ways. I also suggest that they actively construct professional communities with these colleagues and that they find this rewarding and significant. This paper responds to several of the identified themes of the ECER Conference 2015. These include ‘ways in which teachers learn and develop throughout their professional career’. In relation to this, this paper also addresses issues around the conference title 'education and transition'

Modelling the robustness properties of HVAC plant under feedback control

Most existing building simulation programs fail to capture sufficient of the underlying dynamics of nonlinear HVAC plant and some have restricted room space modelling capabilities for low-time-horizon analyses. In this work, a simplified model of a room space with hot water heating and a chilled ceiling system is developed for the main purpose of analysing control system response. The room model is based on a new approach to lumped capacitance modelling and the heating and chilled ceiling emitters are modelled using third-order descriptions. Control system components are treated in detail and both controllers are ‘tuned’ at a nominal region of plant operation using a gradient-descent-based optimization procedure. Robustness qualities of the controllers are analysed with reference to extremes in plant operating conditions. A key feature of the work is the transparency of the modelling procedure, designed to have appeal to researchers as well as practitioners involved with HVAC control system design problems

The development of aerodynamic uncertainties for the space shuttle orbiter

The Shuttle Program development schedule and the management decision to perform an orbital, manned mission on the first launch resulted in a requirement to develop realistic aerodynamic uncertainties for the preflight aerodynamic predictions. This paper addresses the methodology in developing two types of aerodynamic uncertainties. One involves the ability to reproduce aerodynamic results between various wind tunnel tests. The second addresses the difference between preflight aerodynamic predictions and flight results derived from analysis of past aircraft programs. Both types of uncertainties for pitching moment, lateral-directional stability, rudder power, and aileron power are presented. In addition, the application of uncertainties to flight control design and fight test planning is briefly reviewed

Understanding Extended Projected Profile (EPP) Trajectory Error Using a Medium-Fidelity Aircraft Simulation

A critical component of Trajectory-Based Operations is the ability for a consistent and accurate 4-dimensional trajectory to be shared and synchronized between airborne and ground systems as well as amongst various ground automation systems. The Aeronautical Telecommunication NetworkBaseline 2 standard defines the Extended Projected Profile (EPP) trajectory that can be sent via Automatic Dependent Surveillance-Contract from an aircraft to ground automation. The EPP trajectory message contains a representation of the reference trajectory from an aircrafts Flight Management System (FMS). In this work, a set of scenarios were run in a medium-fidelity aircraft and FMS simulation to perform an initial characterization of EPP trajectory errors under a given set of conditions. The parameters investigated were the route length, route type, wind magnitude error, wind direction error, and with and without a required time-of-arrival constraint

Effects of zinc on microalgal biofilms in intertidal and subtidal habitats

Microalgal biofilms are sensitive to environmental conditions. Impacts of contaminants on assemblages of marine biofilm are often investigated in laboratories or in mesocosms. Such experiments are rarely representative of the effects of contaminants on biofilms under natural conditions. Studies in field situations, with enough power to detect impacts, are necessary to develop a better understanding of the effects of contaminants on ecological processes. Metals are a common contaminant of marine systems and can cause disturbances to assemblages. Using a new technique to experimentally deliver contaminants to microalgal assemblages, hypotheses were tested regarding the effects of zinc on microalgal biofilms growing on settlement panels in subtidal and intertidal habitats. PAM fluorometry was used to assess the amount and physiological state of biofilms on panels. Control panels deployed for 1 month in each habitat had significantly greater amounts of biofilm than those exposed to zinc. After deployment for 3 months, the results varied with location. The observed effects on the biofilm did not, however, cause significant changes in the macro-invertebrate assemblages that developed on the panels

Cladding strategies for building-integrated photovoltaics

Photovoltaic cladding on the surfaces of commercial buildings has the potential for considerable reductions in carbon emissions due to embedded renewable power generation displacing conventional power utilization. In this paper, a model is described for the optimization of photovoltaic cladding densities on commercial building surfaces. The model uses a modified form of the ‘fill factor’ method for photovoltaic power supply coupled to new regression-based procedures for power demand estimation. An optimization is included based on a defined ‘mean index of satisfaction’ for matched power supply and demand (i.e., zero power exportation to the grid). The mean index of satisfaction directly translates to the reduction in carbon emission that might be expected over conventional power use. On clear days throughout the year, reductions of conventional power use of at least 60% can be achieved with an optimum cladding pattern targeted to lighting and small power load demands

Construction informatics in Turkey: strategic role of ICT and future research directions

Construction Informatics deals with subjects ranging from strategic management of ICTs to interoperability and information integration in the construction industry. Studies on defining research directions for Construction Informatics have a history over 20 years. The recent studies in the area highlight the priority themes for Construction Informatics research as interoperability, collaboration support, intelligent sites and knowledge sharing. In parallel, today it is widely accepted in the Architecture/Engineering/Construction (AEC) industry that ICT is becoming a strategic asset for any organisation to deliver business improvement and achieve sustainable competitive advantage. However, traditionally the AEC industry has approached investing in ICT with a lack of strategic focus and low level of priority to the business. This paper presents a recent study from Turkey that is focused on two themes. The first theme investigates the strategic role of ICT implementations from an industrial perspective, and explores if organisations within the AEC industry view ICT as a strategic resource for their business practice. The second theme investigates the ‘perspective of academia’ in terms of future research directions of Construction Informatics. The results of the industrial study indicates that ICT is seen as a value-adding resource, but a shift towards the recognition of the importance of ICT in terms of value adding in winning work and achieving strategic competitive advantage is observed. On the other hand, ICT Training is found to be the theme of highest priority from the academia point of view

Rethinking practitioner research in education: not transcribing but reflecting and some reflections on the nature of practitioner research (2nd iteration – Cambridge)

This paper is intended to provoke discussion regarding how different types of research, particularly practitioner research and arts-based research, can inform each other and develop their own rationale for collecting and analysing research data as well as for generating new knowledge. The authors have different backgrounds, one in practitioner research (James), one in arts-based research (Selena) and one in leadership research (Joelma). This paper explores the commonalities they have found, in terms of searching for alternative methodologies for themselves and for those they work with. In this paper, we question some of the dominant approaches to qualitative research, including those that are highly influenced by grounded theory and that typically include creating new data through interviews, then transcribing and coding interviews. The pressure on teachers to find concrete strategies rather than investigate perceptions is discussed in the final section. The paper makes a case for original contributions and alternative approaches towards educational research freed from methodological conventions. It is intended to provoke discussion regarding where the boundaries of innovation may lie in terms of producing research that can still be seen as valid and useful to the researcher and to others. It is one of two papers written concurrently and delivered at conferences just a month apart. The other paper focuses explicitly on the dissemination of research and is entitled: Torn Between Expectations and Imagination: Alternative Forms of Communicating Educational Research (a short discussion paper reflecting on a workshop) (Yuan & Underwood, 2015)
