Luus-Jaakola optimization procedure for some problems in optics
Creators: name: Al-Marzoug, Saeed M
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Physics, Optics.

description: In today's technology an increasing use is made of materials consisting of thin layers with thicknesses in the range of a few nanometers. Applications of these types of materials can be found in integrated circuits, magnetic heads and tapes, solid-state lasers, X-ray mirrors and coated window glass, etc. They are used for their mechanical, magnetic, optical and/or electrical properties. These properties are related to the structural parameters of these materials, such as the elemental composition, thickness, roughness and number of layers in the material. The first part of this thesis explores both the thickness of layers and the number of layers in x-ray multilayer mirrors by using the Luus-Jaakola optimization procedure in order to achieve a desired reflectivity. The reflectivity of multilayer coatings shows a strong dependence on the thickness of each layer and the number of layers. In the first chapter we present and modify the Luus-Jaakola algorithm to design optical th in-film systems by optimizing the thickness of the layers as well as the number of layers. We show that the optimization model can improve the results using fewer layers of material with the Luus-Jaakola method for the design of x-ray multilayer mirrors in both the angular and spectral domains. Numerical results indicate that the proposed approach performs very competitively with other approaches. It has become possible to design optical coatings with fewer layers. This opens a new opportunity for the design of high quality optical coatings. We then apply this technique to help in the design of multilayer mirrors for a target application, such as an astronomical grazing-incidence hard X-ray telescope. These designs are compared with other author's results. Further, we present a computational study of a modification of the Luus-Jaakola method that could be used in multilayer mirrors with more than two components. Then we apply this method to determine the optical constants, thickness and root mean square roughens of the layers. Finally, in the last part of the thesis we present optimization results of phase-only sampled fiber Bragg gratings by using the modified Luus-Jaakola method. We show that it is able to produce a high number of channels with less refractive-index modulation, high reflectivity, as well as requiring fewer segments.

Radical changes in strategy of high technology new ventures
Creators: name: Benjamin, Eyal
Publisher: name: Swinburne
Year: 2024

description: Business strategy occupies a significant place in the business literature, being one of the main pillars of business design and implementation. Scholars and practitioners agree that a strategy well designed and implemented should secure an organization a sustainable competitive advantage within a market. The Resource-Based View (Barney 1991) demonstrated the role of strategy in aligning resources and competences of organizations with their environments. Strategy literature addressed issues of strategy change, noting the cost and risk involved, frequently associating change with poor performance and/or reaction to an anticipated decline. Later research (Lumpkin & Dess 1995) focused on entrepreneurial strategizing, effectual or causal behavior of entrepreneurs (Sarasvathy 2001a) and their ability to aggregate a bricolage of resources in order to 'create something from nothing' (Baker & Nelson 2005). Nevertheless, most of the available literature has not related to fastmoving environments, such as the high technology industry; an industry involving venture capital investors, characterized mainly by its agility and hyperdynamics. New ventures operating in this arena are challenged to realign their strategic orientation, sometimes in an extreme and radical manner. Research to date has not covered in full the issue of Radical Strategic Changes (RSC) of those ventures. The frequency of RSC, and investors‘ perspective on this type of change in their portfolio companies, are at the focus of this study. This research proposes that RSC in high technology new ventures is more frequent than observed in established organizations. It further suggests a linkage between the resources of a new venture and the ignition of a radical change in its strategy. The thesis seeks to evaluate the factors and effects of RSC in high technology new ventures by testing the frequency of the RSC phenomena, followed by the exploration of the factors igniting RSC. Results indicate that the appearance of RSC in high technology new ventures is more frequent than in established organizations and as derived from the literature. It further suggests that internal unfavorable events, as opposed to entrepreneurial opportunities, are more likely to drive radical strategic changes. The investors‘ perspective and implications are discussed as well, demonstrating the importance of the investor-investee relationship in the process of strategy formation in general and for radical strategic change events in particular. As stated by one of the venture capital investors: 'I can hardly think of a successful company that did not change its strategy. It must be a necessity for success.'
Political awakening, identity formation and the other's survival: Bihar's internal re-organization
Creators: name: Marcil, Jacinthe
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Political Science, General.

description: Since Independence in 1947, India has been internally reorganized several times, and new states have been carved out of old ones for various reasons. The latest stage of reorganization occurred in 2000 when the states of Uttaranchal (Uttarakhand), Jharkhand and Chhattisgarh came into being from the remodelling of Uttar Pradesh, Bihar and Madhya Pradesh respectively. The three new states have their under-development in common as well as their sense of injustice about regional exploitation. This research focuses on the case study of Bihar and Jharkhand, situated in the Eastern part of India's Northern Hindi-speaking belt. Two distinct threads are followed: a top-down approach which asks why the central government decided to split Bihar; and a bottom-up approach wondering how the local population -- specifically the tribal one -- managed, throughout the years, to gain political power and to obtain their long-wanted -- yet truncated -- autonomous state within the Indian federation.

description: Tomographic methods on different length scales using different physical principles are well established tools in Materials Science and Engineering (MSE). One of the challenges from a research data management (RDM) perspective in this field is that the tomography process, i.e. data acquisition, is only one part of the entire experimental workflow of materials characterization, which starts with a sample and ends with a reconstructed 3D model. Each step, from sample preparation to data acquisition to post-processing and 3D reconstruction, takes place in its own ecosystem of hardware and software, and there is little standardization in the MSE community on how to collect and use metadata to describe the workflow. This ultimately hinders the (re-)use of data according to the FAIR principles.

In an attempt to improve this situation, we present an excerpt of the ongoing work in Participant Project 13 "Tomography and microstructure-based modeling" of the NFDI-MatWerk consortium. In a collaboration of domain and metadata experts, metadata schemas for the representation of the data acquisition process in FIB/SEM serial sectioning and computed tomography have been developed and implemented using the FAIR Digital Object concept. Furthermore, an automated extraction and mapping service for extracting metadata from existing FIB/SEM tomography datasets and mapping them to the terms of the metadata schema is presented, which provides a one-click solution to collect tomography metadata scattered across different files and write it into a JSON metadata document according to the developed schema. The final result is a FAIR Digital Object pointing to both data and metadata resources. This poster covers both the technical aspects and the researcher's perspective.

description: The WiggleZ Dark Energy Survey measured the redshifts of over 200 000 ultraviolet (UV)- selected (NUV < 22.8 mag) galaxies on the Anglo-Australian Telescope. The survey detected the baryon acoustic oscillation signal in the large-scale distribution of galaxies over the redshift range 0.2 < z < 1.0, confirming the acceleration of the expansion of the Universe and measuring the rate of structure growth within it. Here, we present the final data release of the survey: a catalogue of 225 415 galaxies and individual files of the galaxy spectra. We analyse the emission-line properties of these UV-luminous Lyman-break galaxies by stacking the spectra in bins of luminosity, redshift, and stellar mass. The most luminous (-25 mag < MFUV < -22 mag) galaxies have very broad Hβ emission from active nuclei, as well as a broad second component to the [OIII] (495.9 nm, 500.7 nm) doublet lines that is blueshifted by 100 km s-1, indicating the presence of gas outflows in these galaxies. The composite spectra allow us to detect and measure the temperature-sensitive [O III] (436.3 nm) line and obtain metallicities using the direct method. The metallicities of intermediate stellar mass (8.8 < log (M*/M⊙) < 10)WiggleZ galaxies are consistent with normal emission-line galaxies at the samemasses. In contrast, the metallicities of high stellarmass (10 < log (M*/M⊙) < 12) WiggleZ galaxies are significantly lower than for normal emission-line galaxies at the same masses. This is not an effect of evolution as the metallicities do not vary with redshift; it is most likely a property specific to the extremely UV-luminous WiggleZ galaxies.

description: This thesis consists of two articles that have been submitted to peer reviewed scientific journals. In addition, three introductory chapters precede the articles: one presenting the theory behind the work described in the articles, a second one presenting the methods used for the simulations and a third one summarising results published in literature by different research groups. The first article presents the results of the optimization of the pulse sequence during the electrophoresis of spherical particles in a gel and the presentation of two new types of pulse sequences: the correlated random telegraph signal and the dichotomous signal. Our results show that the optimal ratio of pulse durations in each direction t+/t - should be around 5, compared to a value of 2 or 3 generally used in experiments. In the second article, we explore the dynamics of rod-like DNA fragments in a 2D version of the system of Han et al. [1]. Our simulations present results that contradicts the statement made by Laachi and coworkers [2] why longer chains elude faster at high field: the "torque-assisted escape", where torque turns the DNA chains in a favourable conformation. Our results show that the torque caused by the electric field is in fact in the opposite direction to the movement near the constriction zone. Following those two articles, another chapter presents some supplementary results. The exact calculation method used for the optimization of the pulse sequences was also used to simulate a rotating field in a modified version of the system of asymmetric traps presented by Torres & Slater [3]. Our results show that separation of spheres of different sizes can be made along different directions, offering the possibility of continuous separation. In the second part of this chapter, we present the results of the separation of spherical particles in the system of Han et al. We present a new idea, the pulsed signal, and a new mode of operation with this signal.

description: Oxidative stress (OS) has been linked to the aetiology of many diseases including osteoarthritis (OA). Recent studies have shown that caveolin-1—a structural protein of plasma membrane’s caveolae—is upregulated in response to OS. Here, we explore the function of caveolin-1 in chondrocytes derived from healthy individuals (control) and OA patients that were subjected to exogenous OS. We showed that caveolin-1 was upregulated in response to acute OS in the control, but not in OA chondrocytes. Moreover, OS-induced DNA damage analysis revealed that control cells started repairing the DNA lesions 6 h post-oxidative treatment, while OA cells seemed unable to restore these damages. Importantly, in the control cells, we observed a translocation of caveolin-1 from the membrane/cytoplasm in and out of the nucleus, which coincided with the appearance and restoration of DNA lesions. When caveolin-1 was prevented from translocating to the nucleus, the control cells were unable to repair DNA damage. In OA cells, no such translocation of caveolin-1 was observed, which could account for their inability to repair DNA damage. Taken together, these results provide novel insights considering the role of caveolin-1 in response to OS-induced DNA damage while revealing its implication in the pathophysiology of OA.

description: This paper examines the process by which the social entrepreneurial identity can be constructed through narrative. In so doing, we employ a case study analysis of a social entrepreneur who started, and still operates, a refugee support centre in a major Australian city. This research is timely in light of the current state of academic development of social entrepreneurship (SE) which remains an emerging and under-researched field of academic inquiry (Austin, 2006). In a literature review covering the period between 1990 and 2004, Mair, Robinson and Hockerts (2006) were able to uncover only a handful of academic articles on SE in peer-reviewed journals. Johnson (2000) found similar results, with most references contained in journalistic and professional sources, including internet websites. As such the field remains under-theorised, extremely broad, and bedevilled by a plethora of varying definitions. Our review of the SE literature reveals that it is concentrated in four distinct topic areas: (i) the meaning and conceptualisation of SE (Mort, Weerawardena, and Carnegie, 2003; Thompson, Alvy, and Lees, 2000; Waddock and Post, 1991; Roper and Cheney, 2005; Dees, 1998), (ii) the difference between SE and business entrepreneurship (Austin, Stevenson, and Wei-Skillern, 2006), (iii) the characteristics, motivations, and personal values of social entrepreneurs (Plater-Zyberk, 2005; Hemingway, 2005), and (iv) the activities of social entrepreneurs (Thompson, 2002; Alvord, Brown, and Letts, 2004).

Regulation of IL-7 receptor (CD127) expression on circulating CD8+T cells in HIV infection and its role in cytotoxicity

description: The progressive breakdown of cell mediated immunity is a feature in the pathology of HIV disease. Although not lost from the circulation, with disease progression cytotoxic T lymphocytes (CTL) are less able to contain numerous pathogens including HIV itself. Interleukin (IL)-7 and its signalling via the IL-7 receptor (CD127) is essential for optimal CTL activity. Our demonstration that fewer CD8+ T cells from HIV+ patients express CD127 as compared to healthy individuals, implicates a role for the regulation of CD127 expression in the immunopathogenesis of HIV. Thus, we hypothesize that altered CD127 expression and/or function on CD8+ T cells contributes to impaired cell mediated immunity. This thesis reports an examination of which host or viral factors may be responsible for the down-regulation of CD127 on CD8+ T cells in HIV infection and the mechanism(s) by which these host and/or viral factors decrease CD127 expression on CD8+ T cells. It also assesses whether HIV down-regulates CD127 expression on CD8+ T cells in vitro, and evaluates if the functional capacity of CD127 is altered in HIV infection. Of all the host and viral factors tested, IL-7, IL-4 and HIV-1tat caused a down-regulation in surface CD127 expression on CD8+ T cells, without affecting CD127 mRNA. IL-7 did not increase internalization of surface CD127, but caused shedding of the receptor. Furthermore, In vitro HIV infection of PBMC caused a down-regulation in surface CD127 expression on CD8+ T cells, without affecting CD127 mRNA, and seems to be caused by a soluble factor produced by the infected PBMCs. Finally, in response to IL-7, STAT5 phosphorylation in CD8+CD127 + cells from HIV+ individuals is significantly decreased compared to healthy controls. Proliferation of CD8+CD127 + cells in response to IL-7 is also significantly impaired. These data demonstrate a dysfunction in the IL-7 receptor system that may be explained by IL-7 specific signal transduction defects. As the IL-7/IL-7R system and its disruption during HIV infection continue to be intensively studied, one will get a better understanding of HIV immunopathogenesis and the potential to lead to the development of novel immune based therapies will come about.

description: Background: Maintenance of mean arterial pressure (MAP) at levels sufficient to avoid tissue hypoperfusion is a key tenet in the management of distributive shock. We hypothesized that patients with distributive shock sometimes have a MAP below that typically recommended and that such hypotension is associated with increased mortality. Methods: In this retrospective analysis of the Medical Information Mart for Intensive Care (MIMIC-III) database from Beth Israel Deaconess Medical Center, Boston, USA, we included all intensive care unit (ICU) admissions between 2001 and 2012 with distributive shock, defined as continuous vasopressor support for ≥ 6 h and no evidence of low cardiac output shock. Hypotension was evaluated using five MAP thresholds: 80, 75, 65, 60 and 55 mmHg. We evaluated the longest continuous episode below each threshold during vasopressor therapy. The primary outcome was ICU mortality. Results: Of 5347 patients with distributive shock, 95.7%, 91.0%, 62.0%, 36.0% and 17.2%, respectively, had MAP < 80, < 75, < 65, < 60 and < 55 mmHg for more than two consecutive hours. On average, ICU mortality increased by 1.3, 1.8, 5.1, 7.9 and 14.4 percentage points for each additional 2 h with MAP < 80, < 75, < 65, < 60 and < 55 mmHg, respectively. Multivariable logistic modeling showed that, compared to patients in whom MAP was never < 65 mmHg, ICU mortality increased as duration of hypotension < 65 mmHg increased [for > 0 to < 2 h, odds ratio (OR) 1.76, p = 0.005; ≥ 6 to < 8 h, OR 2.90, p < 0.0001; ≥ 20 h, OR 7.10, p < 0.0001]. When hypotension was defined as MAP < 60 or < 55 mmHg, the associations between duration and mortality were generally stronger than when hypotension was defined as MAP < 65 mmHg. There was no association between hypotension and mortality when hypotension was defined as MAP < 80 mmHg. Conclusions: Within the limitations due to the nature of the study, most patients with distributive shock experienced at least one episode with MAP < 65 mmHg lasting > 2 h. Episodes of prolonged hypotension were associated with higher mortality.

description: Gas-phase controlled mass-transfer for the system, hexane-nitrogen-dodecane has been studied. Three different contacting apparatuses were used: (1) a wetted wall column; (2) a bubble column; (3) a slug-flow absorber. The outlet gas streams from these apparatuses were analysed and the effect of gas-flow rate, liquid flow rate and contact time on overall mass-transfer efficiencies, ET, were investigated. For the wetted wall column mass-transfer efficiencies were found to be a function of column diameter and contact time. The results are found to be consistent with the data of previous investigators. Practically no end-effect mass-transfer took place. For the bubble column, ET, was found to be very high and end-effect mass-transfer predominated. The EE values fell between 0.98 and 0.99. ET was observed to be the function of gas flow rate and contact time. For the slug-flow absorber, mass-transfer efficiencies were again high and end-effect mass-transfer also predominated EE ranging from 0.94 to 0.98. ET was observed to be the function of liquid flow rate as well as gas flow rate, and contact time. Asymtopic values of E T less than 1.0 were observed and are considered to be as the result of incomplete liquid mixing. The effect of liquid flow rate was further studies by varying the position of liquid loading, top or-bottom of the absorber. ET, values were slightly reduced when the liquid was introduced at the top of the column. The overall gas phase mass transfer coefficients were calculated for the rise period mass-transfer. Highest values were found with the bubble column, but are considered to be low in view of the high ET, values observed. Lowest values were found with the slug flow absorber and suggested that mass-transfer was inhibited when bubble movement is restricted. The KOG values for wetted wall column, bubble column and slug-flow absorber, at 50 cc. per min. gas rate, 7 cc. per min. liquid rate and 0.5 cm. I. D. tube, were 0.15 x 10-4, 0.35 x 10-4 and 0.029 x 10-4 g-mole/(sec.) (atm.) (cm.2), respectively. Photographs of bubbles rising in a slug-flow absorber were taken. Slug size was found to be dependent on both gas and liquid flow rate. Variations in gas and liquid rates resulted in the slugs changing in form from an elongated gas slug to a hemispherical cap.

description: Herein, a Mn-based metal–organic framework is used as a precursor to obtain well-defined α-MnS/S-doped C microrod composites. Ultrasmall α-MnS nanoparticles (3–5 nm) uniformly embedded in S-doped carbonaceous mesoporous frameworks (α-MnS/SCMFs) are obtained in a simple sulfidation reaction. As-obtained α-MnS/SCMFs shows outstanding lithium storage performance, with a specific capacity of 1383 mAh g−1 in the 300th cycle or 1500 mAh g−1 in the 120th cycle (at 200 mA g−1) using copper or nickel foil as the current collector, respectively. The significant (pseudo)capacitive contribution and the stable composite structure of the electrodes result in impressive rate capabilities and outstanding long-term cycling stability. Importantly, in situ X-ray diffraction measurements studies on electrodes employing various metal foils/disks as current collector reveal the occurrence of the conversion reaction of CuS at (de)lithiation process when using copper foil as the current collector. This constitutes the first report of the reaction mechanism for α-MnS, eventually forming metallic Mn and Li2S. In situ dilatometry measurements demonstrate that the peculiar structure of α-MnS/SCMFs effectively restrains the electrode volume variation upon repeated (dis)charge processes. Finally, α-MnS/SCMFs electrodes present an impressive performance when coupled in a full cell with commercial LiMn1/3Co1/3Ni1/3O2 cathodes.

description: The mechanical properties of four reinforcing steel bars were evaluated in the temperature range from -40°C (-40°F) to 40°C (104°F). The steel bars were: #9G60 (sigmays = 60 ksi), #9G40 (sigma ys = 40 ksi), #6G60 (sigmays = 60 ksi), and #6G40 (sigma ys = 40 ksi). Both tension and Charpy V-notch Impact tests were performed in the present study. The tensile tests were carried out using a portable loading frame. A hydraulic cylinder was used to provide the force necessary to pull the specimen to rupture and the load on the specimen was measured by means of three calibrated load cells. The strains were measured with a 2" gage length extensometer, and the fracture strain was measured with calipers. The results of the tension tests showed that the yield and fracture stresses increase with decreasing temperature. The magnitude of the fracture strain does not change markedly with temperature. No consistent pattern can be discerned for the variations of yield strain with temperature. The Charpy impact tests were conducted by an Avery Charpy Impact Testing machine with a striking velocity of 16.5 ft per sec and an initial energy 220 ft lb loaded as a simple beam configuration. The Charpy impact test showed that the steel bar lost impact resistance when the testing temperature was decreased. In this report, the results of the tests were summarized to show the relationships between (1) yield stress vs temperature behavior curves, (2) fracture stress vs temperature curves, (3) yield strain vs temperature, (4) fracture strain vs temperature, (5) stress-strain curves at each temperature, and (6) the Charpy Impact energy vs various temperature curves.

description: Marriage and close intimate relationships are probably the most intense of all social relationships. Research indicates that individuals who commence an intimate relationship do so with an overly positive perception of their selected partner. The present study aimed to determine at what time in a relationship individuals begin to acknowledge both the negative as well as the positive qualities of their partner - to remove the “rosecoloured- glasses”, so to speak. Sixty-two individuals participated in the study, 30 males (M=29.9, SD=3.1) and 32 females (M=28.5, SD=3.2). Mean length of intimate relationship was 5.2 years for the sample, with 48.4% indicating a ‘married’ status for their relationship. A modified version of the Relationship Assessment Scale (Hendrick, 1988) and the Positive and Negative Qualities in Marriage Scale (Fincham and Linfield, 1997) were used to determine the satisfaction respondents had with their intimate relationship overall and the degree to which the positive and negative qualities of the intimate relationship were acknowledged as present in the relationship. Results indicate that those individuals currently in a relationship in excess of 3 years in length are significantly more likely to recognise the negative qualities of their intimate partner, but are not likely to assess the relationship in general as negative. Implications of the study’s finding are discussed and suggestions for further research are made.

description: Coordinated atomic actions (CAAs) have been used in a semi-formal way for the design of the production cell case study. This paper presents a formal specification and verification of the production cell building on this design. However, this report is not intended to present yet another formalization of the production cell case study but rather as an approach to formalizing a CAA based system design in order to formally verify its properties. Each CAA is modeled as an atomic state transition characterized by its pre- and postconditions. In order for such transitions to become enabled, conditions are formalized requiring all associated roles to be activated. Activation of roles is performed by controllers, which are again modeled in terms of state transitions. The state space of the production cell can be viewed as being finite; hence, the production cell is specified as a finite state transition system and the formal verification of the CAA-design is carried out using model-checking.

description: Transport is not only an indispensable part of our daily lives, but also one of the major sources of greenhouse gases in Germany. What can be done to reduce greenhouse gas emissions from transport in the short- and mid-term? How can transport become greenhouse gas-neutral in the long term? Are Germany’s climate targets in the transport sector sufficiently ambitious? This paper answers these questions. It describes what needs to be done in the coming years to reconcile developments in the transport sector with the commitments of the Paris Climate Agreement and the German government’s Climate Action Plan 2050. It suggests measures that can help to achieve a quick and significant reduction in greenhouse gas emissions, ensuring that the climate targets agreed upon in Paris could be met by Germany’s transport sector.

description: Background: Conducting and/or disseminating research together with community stakeholders (e.g. policy-makers, practitioners, community organisations, patients) is a promising approach to generating relevant and impactful research. However, creating strong and successful partnerships between researchers and stakeholders is complex. Thus far, an in-depth understanding of how, when and why these research partnerships are successful is lacking. The aim of this study is to evaluate and explain the outcomes and impacts of a national network of researchers and community stakeholders over time in order to gain a better understanding of how, when and why research partnerships are successful (or not). Methods: This longitudinal multiple case study will use data from the Canadian Disability Participation Project, a large national network of researchers and community stakeholders working together to enhance community participation among people with physical disabilities. To maximise the impact of research conducted within the Canadian Disability Participation Project network, researchers are supported in developing and implementing knowledge translation plans. The components of the RE-AIM framework (reach, effectiveness, adoption, implementation and maintenance) will guide this study. Data will be collected from different perspectives (researchers, stakeholders) using different methods (logs, surveys, timeline interviews) at different time points during the years 2018–2021. A combination of data analysis methods, including network analysis and cluster analysis, will be used to study the RE-AIM components. Qualitative data will be used to supplement the findings and further understand the variation in the RE-AIM components over time and across groups. Discussion: The outcomes, impacts and processes of conducting and disseminating research together with community stakeholders will be extensively studied. The longitudinal design of this study will provide a unique opportunity to examine research partnerships over time and understand the underlying processes using a variety of innovative research methods (e.g. network analyses, timeline interviews). This study will contribute to opening the ‘black box’ of doing successful and impactful health research in partnership with community stakeholders.

Digital Cultural Communication: enabling new media and co-creation in Asia

description: Digital Cultural Communication (DCC) is a new field of research and design which seeks to build a co-creative relationship between the cultural institution and the community by using new media to produce audience-focused cultural interactive experiences (Russo and Watkins, 2005). By situating the development of cultural communities within DCC, the institution adopts a more representative curatorial practice and benefits through the creation of original community-derived content which can form new digital collections. The community benefits through improved ‘information literacy’ – the skills required to use digital technologies to engage in both cultural consumption and production (Russo and Watkins, 2004) – and can go beyond being a stakeholder of an institutional exhibition. Information literacy skills enable the community to both produce and consume its own original cultural content, in the form of narratives, wikis, blogs, vlogs or any other medium which is supported by the institution and connects to the audience. The institution ceases to be the sole custodian of cultural experience; instead it provides co-creative infrastructure for the community and distributes original cultural content to the audience via multiple platforms – physical, online and broadcast. This article uses a range of examples from around Asia to demonstrate how individuals and communities can benefit from the economy and immediacy offered by new media to co-create and distribute distinctive cultural content to broader audiences.
