description: A modular multifunctional façade for the retrofit of shopping malls, capable of adapting to different climates and to the existing building features both by the presence of movable components and by proper sizing of the fixed ones, is under development within the European FP7 project CommONEnergy. In particular, this curtain-wall façade is equipped with a fixed shading system, a photovoltaic panel with a battery feeding the automated openings for natural ventilation. The aim of this work is to define a reliable parametric model for a multi-functional façade system, to support designers with a set of useful data for the holistic design of the façade configuration depending on climate, orientation and building use. Firstly, a reference zone model for the façade was devised; this had to be both representative of reality and smartly defined for simulation software implementation. Besides the definition of the façade model parameters, all unknown design parameters were identified with their minimum and maximum values, depending on different possible applications and environmental conditions in which the façade could be applied. The inputs for the model were defined in a parametric matrix and included: facade module size, façade orientation, climate, window typology (thermal transmittance and g-value), distance between the shading lamellas, tilt angle, and openable window size. The simulation engine was decoupled: visual comfort and artificial lighting use were assessed with Radiance, while the façade thermal behaviour was evaluated by means of building energy simulations in TRNSYS, taking into consideration the daylight assessment results. For each simulated configuration, a set of relevant outputs fields for Indoor Air Quality, thermal and visual comfort, and energy performance were derived. The main considered performance indicators were the long-term percentage of people dissatisfied, the number of hours when CO2 concentration was within the recommended values for each of the categories defined by EN 15251:2007, the illuminance provided by daylight, the energy consumption due to lighting, ventilation, heating and cooling, and the energy generated by the PV panel. Moreover, all outputs were collected in a pre-design support tool comprised of a database accessible through a filtering system to gather the desired performances. This work highlights the role of thermal and daylighting simulation in the design of an adaptive multifunctional façade through the definition of a methodology for the support at the pre-design phase.

description: Dear JFDE Readers and Authors, This issue is the result of the facade conference Powerskin, held on 19 January 2016 at the building tradefair ‘Bau’ in Munich. The conference was organised in a cooperation of TU Munich, TU Darmstadt and TU Delft. All three universities maintain a facade research and education unit on building envelopes. The conference featured a mix of practice and education related and scientific contributions. Again, JFDE was chosen as the platform to publish a selection of scientific papers. A total of 22 abstracts were reviewed of which 17 were pre-selected. From those, we received 13 papers that had been subjected to our strict double blind peer review process. A final selection of 9 papers forms this issue. We thank our guest editors Thomas Auer and Jens Schneider who have been key partners in creating this special issue. As discussed in the last editorial, we have successfully completed the NWO funding period (Netherlands Organisation of Scientific Research) to start up JFDE. Open Access publishing strongly depends on author publishing fees and the introduction in our scientific ((field?)) needs some more time. In search of a new business model, we proudly announce that we have found two partners wo believe in the relevance of JFDE. The Society of Facade Engineering SFE is a joint initiative of CIBSE, IStructE and the RIBA with the aim to create a forum to advance knowledge and practice in facade engineering. CWCT It is an industry funded centre and a leading information provider and trainer in the field of building envelopes and glazing. Both organisations acknowledge the need for an independent scientific publishing organ which will contribute to the development of the field of facade design, engineering and construction. This support enables us to continue JFDE. We want to thank the publisher IOS Press and especially Mark Eligh to have guided JFDE to the level where it is now. This issue is the first published by TU Delft Open, a publishing house established by the TU Delft Library. We will continue to deliver high quality contributions with the aim of 3 issues per year. Thank you for supporting JFDE. The editors in chief, Tillmann Klein Ulrich Knaack

Magnetosphere-Ionosphere Coupling Through E-region Turbulence 1: Energy Budget

description: During periods of intense geomagnetic activity, strong electric fields and currents penetrate from the magnetosphere into high-latitude ionosphere where they dissipate energy, form electrojets, and excite plasma instabilities in the E-region ionosphere. These instabilities give rise to plasma turbulence which induces non-linear currents and strong anomalous electron heating (AEH) as observed by radars. These two effects can increase the global ionospheric conductances. This paper analyzes the energy budget in the electrojet, while the companion paper applies this analysis to develop a model of anomalous conductivity and frictional heating useful in large-scale simulations and models of the geospace environment. Employing first principles, this paper proves for the general case an earlier conjecture that the source of energy for plasma turbulence and anomalous heating equals the work by external field on the non-linear current. Using a two-fluid model of an arbitrarily magnetized plasma and the quasilinear approximation, this paper describes the energy conversion process, calculates the partial sources of anomalous heating, and reconciles the apparent contradiction between the inherently 2-D non-linear current and the 3-D nature of AEH.

description: I met Peter J. Bickel for the first time in 1981. He came to Jerusalem for a year; I had just started working on my Ph.D. studies. Yossi Yahav, who was my advisor at this time, busy as the Dean of Social Sciences, brought us together. Peter became my chief thesis advisor. A year and a half later I came to Berkeley as a post-doc. Since then we have continued to work together. Peter was first my advisor, then a teacher, and now he is also a friend. It is appropriate that this interview took place in two cities. We spoke together first in Jerusalem, at Mishkenot Shaananim and the Center for Research of Rationality, and then at the University of California at Berkeley. These conversations were not formal interviews, but just questions that prompted Peter to tell his story.

More precisely, C_T is bounded from below by a universal function of the dimensions of the lowest and second-lowest scalars present in the CFT. The method uses the crossing symmetry constraint of the 4-point function, analyzed by means of the conformal block decomposition.

Magnetosphere-Ionosphere Coupling Through E-region Turbulence: Anomalous Conductivities and Frictional Heating

description: Global magnetospheric MHD codes using ionospheric conductances based on laminar models systematically overestimate the cross-polar cap potential during storm time by up to a factor of two. At these times, strong DC electric fields penetrate to the E region and drive plasma instabilities that create turbulence. This plasma density turbulence induces non-linear currents, while associated electrostatic field fluctuations result in strong anomalous electron heating. These two effects will increase the global ionospheric conductance. Based on the theory of non-linear currents developed in the companion paper, this paper derives the correction factors describing turbulent conductivities and calculates turbulent frictional heating rates. Estimates show that during strong geomagnetic storms the inclusion of anomalous conductivity can double the total Pedersen conductance. This may help explain the overestimation of the cross-polar cap potentials by existing MHD codes. The turbulent conductivities and frictional heating presented in this paper should be included in global magnetospheric codes developed for predictive modeling of space weather.

Investigation into DNA methylation and gene expression profiles of imprinted regions in infants conceived via assisted reproductive technologies
Creators: name: Vincent, Rebecca Naomi
Publisher: name: University of British Columbia
Year: 2015

description: A correlation has been found between babies born through assisted reproductive technologies (ARTs) and an increased risk of genomic imprinting disorders such as Beckwith-Wiedemann syndrome (BWS), Angelman syndrome (AS), and Silver-Russell syndrome (SRS), as well as other diseases in later life such as diabetes and obesity. In order to assess whether in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) impact the establishment of DNA methylation and/or gene expression patterns of imprinted regions, cord blood and placental tissue were collected from babies born after IVF and ICSI infertility treatments, as well as from naturally conceived controls. DNA methylation levels at the PLAGL1, KvDMR1 and PEG10 differentially methylated regions (DMRs) and their corresponding gene expression levels were analyzed due to their association with known imprinting disorders and influence on fetal and placental development. Methylation at the LINE-1 repetitive element was also analyzed as an indicator of global DNA methylation. We discovered a small, but significant increase in DNA methylation at the DMR of the tumor suppressor gene, PLAGL1, in cord blood from IVF pregnancies, as well as a lack of methylation at PEG10 in cord blood from all groups. We also found decreased levels of PLAGL1 gene expression in the IVF and ICSI groups, and decreased expression of KCNQ1OT1 and increased expression of IGF2 in IVF cord blood samples, which may suggest the disruption of an imprinted gene network involving chromosome 11p15.5. These findings indicate that the PLAGL1 DMR may be susceptible to epimutations in the ART population and could potentially lead to increased risk of imprinting disorders, intrauterine growth restriction and cancer susceptibility in ART conceived infants.
Excitation of relaxation oscillations in a semiconductor superlattice by incident waves: efficient terahertz harmonics generation

description: Generation of terahertz harmonics by frequency multiplication with a semiconductor superlattice due to an excitation of relaxation oscillations by incident waves is investigated theoretically. It is shown that the relaxation oscillations excitation becomes feasible if the superlattice dc resistance is low enough in comparison with a characteristic radiation impedance of the external waveguide system. The power of the generated harmonics as a function of the incident wave power demonstrates a threshold-like behavior at a specific input power level dependent on the superlattice peak current. We demonstrate that for typical superlattice parameters the roll-of frequency of the generated harmonics is mostly specified by the plasma frequency of electrons in a superlattice miniband. We argue that an increase of the superlattice miniband widths could essentially enhance both the efficiency and the spectral range of the generated terahertz harmonics.

Thermal, Energy and Daylight Analysis of Different Types of Double Skin Facades in Various Climates
Creators: name: Aksamija, Ajla
Publisher: name: Journal of Facade Design and Engineering
Year: 2018

description: This article explores thermal, energy and daylighting performance of double skin facades (DSFs) in different climate types, specifically focusing on three typologies: box window, corridor and multi-story DSFs. These systems were investigated and analyzed to determine how different DSFs perform in comparison to each other, as well as a typical curtain wall (single skin glazed facade used as a baseline), in a multitude of climate applications. The utilized research methods included two-dimensional heat transfer analysis (Finite Element Method analysis), Computational Fluid Dynamics (CFD) analysis, energy modeling, and daylight simulations. Heat transfer analysis was used to determine heat transfer coefficients (U-values) of all analyzed facade types, as well as temperature gradients through the facades for four exterior environmental conditions. CFD analysis investigated three-dimensional heat flow, airflow and air velocity within air cavity of DSFs. Energy modeling and daylight simulations were conducted for an office space, which was enclosed by the analyzed facade types. Individual energy models were developed for each facade type and for fifteen different climates representing various climate zones and subzones, from very hot to arctic. For daylighting simulations, multiple models were developed to study investigated typologies of DSFs, depth of air cavity between the two skins, orientations and four climate types, as well as different sky conditions. Results indicate that there is not a lot of variation in thermal performance of the different DSF types, but that all DSF facades would have significantly improved thermal performance compared to the baseline single skin facade. Energy modeling results indicate significant differences in performance between the DSFs and single skin facade, but fewer variations between the different typologies of investigated DSFs. Moreover, the results show the effect of DSFs in different climate types on energy performance, heating, cooling and lighting loads. Daylighting results indicate that all types of DSFs would decrease daylight levels compared to a conventional curtain wall, however, the differences between lighting levels are also dependent on the orientation, air cavity depth, facade type and climate.

description: Ammonia is not only the most important chemical for fertilizer production, it has also gained much interest as a future hydrogen storage material. Besides the well-known Haber–Bosch process to generate ammonia from elemental sources, new ways to convert nitrogen into ammonia have been investigated in the last decade for a decentralized production, including electrocatalytic and photocatalytic approaches. However, photocatalysis in particular suffers from stagnating materials development and unstandardized reaction conditions. In this Review, we shine light on recent materials and reaction engineering results for photocatalytic nitrogen reduction, putting an emphasis on the need to connect the activity of reported materials together with detailed reaction conditions and efficiencies. Photocatalytic nitrogen reduction is an emerging field that will certainly gain significant interest in the future as a sustainable pathway to generate green hydrogen and ammonia. The field will certainly strongly benefit from joint efforts with strong interactions between chemists, physicists and chemical engineers at a fundamental level.
Classification of Oblique Grids in Curtain Walls: A Case-Study of Design Strategies in Modular Edge-Panels
Creators: name: Brzezicki, Marcin Michal
Publisher: name: Journal of Facade Design and Engineering
Year: 2018

description: Recent developments in façade engineering allow for much more freedom in designing façade grids, including various tessellations. This paper reviews different geometrical configurations in order to provide a framework for the understanding and classification of façades based on oblique grids. On the basis of case studies, this paper analyses oblique grids used in planar light-transmitting façades and evaluates existing geometries. The main difficulties linked to edge panels are: (i) the high number of unique panels and (ii) their irregular shape, which complicates the building process. This paper serves as a review of the currently used technologies and of the possible design solutions aimed at decreasing the number of unique panels. As a result, the applied strategies lower the costs and simplify the manufacturing process and installation of the façade’s panels. Technologies that directly link façade geometries created using CAD software with manufacturing processes offer the possibility to use non-rectangular solutions on a much wider scale.

Using parametric BIM integration for prototyping future responsive facades
Creators: name: Mallasi, Zaki
Publisher: name: Journal of Facade Design and Engineering
Year: 2018

description: Architectural facades throughout the history have been designed to respond to environmental, social and functional conditions among other considerations. Advancements in Digital Design Computation (DDC) emerged as an essential support for exploring and creating contemporary architectural facades. Current research attempts seeking responsive kinetic facade revealed different methods of integrating kinetics into the physical facade. However, some case studies indicated that physical façades struggled to achieve the anticipated kinetic responses after a facade is constructed. In addition, the process is formal, prescribed, lacks flexibility and can only assist the designer in the visualization of the design. As a consequence, the challenges in understanding the process of connectivity between digital/physical kinetics are important to address in the early design stage. Digital and physical façade prototypes would allow designers to test the qualities of such system before constructing full-size mock-ups and discover new modes of parametric design thinking in architecture. In this work, we report on an ongoing development of a custom Add-on utilizing Autodesk ® Revit application that connects between the kinetic properties of the digital and physical model to control dynamic façade. We deployed the Revit Application Programming Interface (API) C# programming to manipulate the kinetic response through linear actuation. The system framework proposes a practical mechanism connecting solar exposure values to a Building Information Model (BIM). In this process, an Arduino Mega board, servo motors, tooth-beam and tensile-fabric material were used to construct the small physical prototype and program its automation. While adding to previous research, we are tackling three challenges. The first is to dynamically harness the response mechanism of kinetic façade so that to avoid uninformed design decision making. The second is to map the digital/physical kinetic properties in terms of: modeling, process and function. The third is to assess the benefits from our approach of connecting BIM parametric model with physical prototypes. Our experimental project demonstrates how data could be transformed digital/physical façade model. We conclude by observations from this work on how BIM parametric modeling with design computation could influence the future direction of kinetic façade systems.

description: Designing the facade of a building is a complex task due to the multiple criteria to consider and the number of stakeholders involved. This paper highlights the influence criteria, the requirement and the issues relative to the selection of cladding material for non-residential buildings. Architects, contractors, subcontractors and clients provide a systemic view of the situation, based on an analysis of the findings from a mixed-research method combining online survey and semi-structured interviews. The results show that the decision for the cladding material is mainly influenced by building type, client type, project context, personal experience, product reputation and project delivery methods. The most important requirement for architects, in terms of cladding materials are, in order, performance, appearance, and good warranties. Contractors and subcontractors look especially for compliance with the delivery schedule, with an optimal deadline of less than three weeks. Regarding installation, subcontractors seek speed of installation, system simplicity, easy coordination with envelope workers and on-site product modulation. Finally, the main issues with cladding are maintenance, newness of cladding systems, lack of construction detail, and tendering process. A better understanding of the cladding selection process provides valuable insight to the manufacturer in order to provide the right information to satisfy stakeholder’s need.

description: A concept for a smart material morphing building surface tile that would utilize adaptive surface wrinkle patterns to improve solar interaction is explored. The effect of the wrinkle patterns is numerically investigated in the context of an objective to reduce solar irradiance entering buildings by changing the shape of the surface (i.e., surface topography) so that the facade is self-shading, thereby reducing energy costs of the building for temperature control. A generally applicable algorithm was utilized and is presented to quantify the area of an arbitrarily shaped/oriented surface that is in shade for any given date/time and geographic location. Numerical case studies are shown that utilize the surface shading algorithm to evaluate the capabilities of various basic wrinkle patterns, both static and dynamically changing, to self-shade a building surface over the course of a day. The results indicate that a morphing wrinkle pattern can substantially increase the amount and duration of surface area in shade over time in comparison to any of the static (non-morphing) patterns, although it is noted that there is an expected tradeoff in the energy cost to change the surface pattern. Furthermore, it is shown that as the location of the proposed tile on the building facade changes, the optimal wrinkle pattern changes as well.

description: We investigate the phase diagram of a discrete version of the Maier-Saupe model with the inclusion of additional degrees of freedom to mimic a distribution of rodlike and disklike molecules. Solutions of this problem on a Bethe lattice come from the analysis of the fixed points of a set of nonlinear recursion relations. Besides the fixed points associated with isotropic and uniaxial nematic structures, there is also a fixed point associated with a biaxial nematic structure. Due to the existence of large overlaps of the stability regions, we resorted to a scheme to calculate the free energy of these structures deep in the interior of a large Cayley tree. Both thermodynamic and dynamic-stability analyses rule out the presence of a biaxial phase, in qualitative agreement with previous mean-field results.
Integrated Facades as a Product-Service System: Business process innovation to accelerate integral product implementation

description: The Circular Economy (CE) attempts to realign business incentives, across all fields of human industry, to support the preservation of raw materials within closed economic loops. Within this conceptual frame, Product-Service Systems (PSS) combine the use of tangible products such as building technologies, with intangible maintenance and monitoring services, to enhance the delivery of valuable performances while limiting the use of materials and other resources. This paper explores the potential for the application of CE and PSS organization principles in the delivery of Facades-as-a-Service. It explores how the benefits brought about by this way of thinking: Lower initial capital requirements, material ownership retention by suppliers, and long-term interdisciplinary collaboration, could lead to a more efficient façade construction industry, while accelerating the rate of building energy renovations. Within the current process for designing, manufacturing, and operating facades there is a gap between supply-side discoveries and demand-side needs, which hinders the implementation of resource-efficient facades. Facade leasing as a form of product-service system keeps suppliers committed, throughout the building’s service-life, to safeguard optimum performance in operation, while actively stimulating clients to adopt innovative technical solutions. The paper elaborates on both supply-side facade innovations and the demand-side conditions necessary to implement such business models, while exploring the costs and benefits of product-service systems as new business-to-client models to connect supply and demand. It builds upon the research project “Facade leasing” (MSc thesis by Azcarate-Aguerre, J.F., 2014) and combines knowledge about facade design and engineering (supply-side approach) with the knowledge about client needs, performance criteria, and willingness to pay (demand-side approach). The research methodology includes literature review and expert interviews, integrating both theory and practice. This paper argues that a Product-Service System approach to facade design, construction, operation and renovation could accelerate the rate and depth of building energy renovations. It could also provide incentives to supply- and demand-side stakeholders, to implement Circular Economy principles through new models of ownership, contracting, and service delivery. It aims at establishing the general conceptual frame of a Product-Service System for leasable facades, setting the basic parameters to be taken into account when designing a PSS-based business model, and formulating its value proposition.

description: The paper presents an innovative approach to the retrofitting of the adaptive ventilated facade module developed in the EU project E2VENT. The E2VENT innovative facade module is targeted to Optimal Adaptability and Heat Exchange for the refurbishment of existing buildings and is composed of two main parts: an adaptable smart modular heat recovery unit (SMHRU), which is adjustable to work within the ventilated façade cavity, is able to recover heat from ventilation air, and can preheat ventilation air in winter while precooling it in summer; and a latent thermal heat energy storage system (LTHES) which is based on phase change materials fitting in the cavity and is complementary to the SMHRU. Following a brief introduction of the E2VENT project, the integration of the new technology at the building scale, and analysis of the foreseen design issues in terms of interfaces and façade singularities shall be discussed. The paper will discuss how the systemic managing of these issues at the design level is vital in preventing inconsistencies between parts and helps with the design team working process.

description: These days, we are constantly expecting more from the performance of the building envelope with regard to both comfort and ecological compatibility. Operational energy has been undergoing significant improvement, which in turn draws attention to the building matter: If a standard building does not consume energy in its operation, then it is the building material that impacts the level of environmental compatibility. Designing with used building matter offers an opportunity to decrease emissions from extraction, preserve primary resources and reduce landfill. On top of that, the EU waste directive requires all new construction to have a recycling concept for 70% of the building mass (Commission, 2013). This paper deals with a new approach to deconstructing used building elements and re-introducing them in new construction on a regional scale. A well-connected network of stakeholders increases the regional recycling potential. On a technical scale, the deconstruction process needs to be improved so that it becomes more safe and economically competitive. Robotic disassembly shows great potential to simplify the process and restore high valuable recycling. Deconstruction processes can be arranged in a mobile way with a wide range of tools. Such tools can be equipped to relate to the flexible layout of machines, thus allowing individualized adaptation to the building envelope.

description: We investigate the nature of objects in a complete sample of 28 galaxies selected from the first sky area fully covered by ALFALFA, being well-detected and having HI profiles wider than 550 km/s. The selection does not use brightness, morphology, or any other property derived from optical or other spectral bands. We investigate the degree of isolation, the morphology, and other properties gathered or derived from open data bases and show that some objects have wide HI profiles probably because they are disturbed or are interacting, or might be confused in the ALFALFA beam. We identify a sub-sample of 14 galaxies lacking immediate interacting neighbours and showing regular, symmetric, two-horned HI profiles that we propose as candidate high-mass disk systems (CHMDs). We measure the net-Halpha emission from the CHMDs and combine this with public multispectral data to model the global star formation (SF) properties of each galaxy. The Halpha observations show SFRs not higher than a few solar masses per year. Simple SF models indicate that the CHMDs formed most of their stars almost a Hubble time ago, but most also underwent an SF event in the last 1-10 Myrs; the young stars now produce 10 to 30% of the visible light. The spatial distribution of the SF-regions is compatible with recycled stellar ejecta. We calculate representative dynamical masses from 1 to $\sim7 10^{11}$ M_sun, larger by factors of 2.5 to 7.5 than the baryonic masses of the luminous stars and gas. We test the Tully-Fisher relation for the CHMDs and show that these lie below the relation defined for lower mass galaxies, i.e., that their M_dyn is lower than expected when extrapolating the relation from lower mass galaxies to higher HI line widths.

Directions for the design of energy efficient kinematics in adaptive solar building envelopes
Creators: name: Basso, Paolo
name: Del Grosso, Andrea E.
Publisher: name: Journal of Facade Design and Engineering
Year: 2017

description: The development of adaptive building envelopes is receiving increasing interest in contemporary architecture, as it strives to cope with several requirements such as energy saving and harvesting (or mitigating environmental actions), improving performance and, finally, aesthetics. Actual implementation fundamentally concerns external “skins” (i.e. adaptive façades), but internal “skins” (e.g. adaptive ceilings) may also be developed. The engineering aspects related to the above developments are quite complex and involve different behavioral models to be merged within the adaptive strategy. In the present paper, a study is presented that concerns the conception of an adaptive origami-like solar skin. The main design issues in managing the kinematics of the envelope are then identified and the envisaged solutions, to be developed in the next stage of the research, are discussed.

description: The new calculation tool EvalDRC enhances current strategies for the simulation of Daylight Redirecting Components (DRCs). It is built upon RADIANCE as a core simulation engine and uses the daylight coefficient method, climate based sky models for annual simulations, and daylight metrics for data reduction. Contribution Photon Mapping is introduced as a new method for physically correct DRC simulation. Further new features are separate: True Sun Coefficients for a less approximated, more accurate treatment of the sun contribution and monthly breakdowns of the Spatial Daylight Autonomy and Annual Sunlight Exposure metrics for more detailed information about DRC performance over the course of the year. To show the versatility of the tool, two application studies were carried out in which either measured Bidirectional Scattering Distribution Functions (BSDF) or detailed geometry models were used for the DRC simulation.

Teaching and learning perspectives of clinical instructors within a Canadian dental hygiene program
Creators: name: Waldron, Shannon Kerry
Publisher: name: University of British Columbia

description: Entry to Practice Competencies and Standards is a document that sets the guidelines of curriculum for all Canadian dental hygiene programs. Within the document, a competency-based curricular aim is emphasized. As contemporary educational literature have been suggesting, student centered learning has become a dominant guiding principle of pedagogical approaches for competency-based education. With shifting curricular aims and pedagogical principles many current educators of dental hygiene programs may be teaching new curricula different to that which they experienced when they were students in dental hygiene programs. Furthermore, many of them may be expected to implement pedagogical approaches that are different from how they were taught due to traditional conceptions of how people learn. This study explores the perspectives on teaching and learning held by clinical dental hygiene instructors at one Canadian institution. The objective is to understand which teaching and learning perspectives dental hygiene instructors hold. Data were collected through semi-structured interviews with fifteen instructors. The results show that instructors tend to think of their teaching as student-centered, yet in a set of 'simulated teaching' questions, the responses were found to be teacher-centered. The research also revealed that the process by which one learns to become a clinical dental hygiene instructor is multifactorial. These factors include but are not limited to the following: instructors' perceptions of their own learning experiences, instructors' experiences of inter- instructor collaboration, and instructors' methods of facilitating student self-efficacy. Given curricular change and the emergence of literature supporting a student-centered approach to teaching and learning, this study shows that it is critical to uncover the teaching/learning beliefs of the instructor's prior to designing faculty development programs. Integrating instructors'preconceptions into the program design may create an environment that is more accommodating of the transition towards the new pedagogical culture.
