Collaborative research and development (R&D) for climate technology transfer and uptake in developing countries: Towards a needs driven approach

While international cooperation to facilitate the transfer and uptake of climate technologies in developing countries is an ongoing part of climate policy conversations, international collaborative R&D has received comparatively little attention. Collaborative R&D, however, could be a potentially important contributor to facilitating the transfer and uptake of climate technologies in developing countries. But the complexities of international collaborative R&D options and their distributional consequences have been given little attention to date. This paper develops a systematic approach to informing future empirical research and policy analysis on this topic. Building on insights from relevant literature and analysis of empirical data based on a sample of existing international climate technology R&D initiatives, three contributions are made. First, the paper analyses the coverage of existing collaborative R&D efforts in relation to climate technologies, highlighting some important concerns, such as a lack of coverage of lower-income countries or adaptation technologies. Second, it provides a starting point for further systematic research and policy thinking via the development of a taxonomic approach for analysing collaborative designs. Finally, it matches characteristics of R&D collaborations against developing countries’ climate technology needs to provide policymakers with guidance on how to Configure R&D collaborations to meet these needs

Specific Internalisation of Gold Nanoparticles into Engineered Porous Protein Cages via Affinity Binding

Porous protein cages are supramolecular protein self-assemblies presenting pores that allow the access of surrounding molecules and ions into their core in order to store and transport them in biological environments. Protein cages’ pores are attractive channels for the internalisation of inorganic nanoparticles and an alternative for the preparation of hybrid bioinspired nanoparticles. However, strategies based on nanoparticle transport through the pores are largely unexplored, due to the difficulty of tailoring nanoparticles that have diameters commensurate with the pores size and simultaneously displaying specific affinity to the cages’ core and low non-specific binding to the cages’ outer surface. We evaluated the specific internalisation of single small gold nanoparticles, 3.9 nm in diameter, into porous protein cages via affinity binding. The E2 protein cage derived from the Geobacillus stearothermophilus presents 12 pores, 6 nm in diameter, and an empty core of 13 nm in diameter. We engineered the E2 protein by site-directed mutagenesis with oligohistidine sequences exposing them into the cage’s core. Dynamic light scattering and electron microscopy analysis show that the structures of E2 protein cages mutated with bis- or penta-histidine sequences are well conserved. The surface of the gold nanoparticles was passivated with a self-assembled monolayer made of a mixture of short peptidols and thiolated alkane ethylene glycol ligands. Such monolayers are found to provide thin coatings preventing non-specific binding to proteins. Further functionalisation of the peptide coated gold nanoparticles with Ni2+ nitrilotriacetic moieties enabled the specific binding to oligohistidine tagged cages. The internalisation via affinity binding was evaluated by electron microscopy analysis. From the various mutations tested, only the penta-histidine mutated E2 protein cage showed repeatable and stable internalisation. The present work overcomes the limitations of currently available approaches and provides a new route to design tailored and well-controlled hybrid nanoparticles

Exploring the Natural Attributes of Principals as Educational Leaders

This study sought to explore the leadership of principals as educational administrators based on their natural attributes. The excellence in the actions of principals as educational administrators will serve as the determining factor for the success of a school across nine fields listed in the Malaysian School Principals Competency Standards. This success is mainly driven by the natural attributes of principals’ leadership in influencing the processes and behaviour of teachers in the delivery of education. This study also explores leadership issues and problems that are still of current interest. Principals’ competency levels in executing leadership still show that teachers are constrained by numerous flaws particularly in the teaching and learning in schools. Such conditions are often mirrored in schools with poor leadership display by Principals who are bent on putting off planned educational programmes. This qualitative study was done as a single case study. Qualitative data obtained via interviews with 10 informants in school formed the research case. The interviews were semi-structured and were analysed manually using category classification. The interviews explained the natural attributes reflected via Principals’ leadership orientation to answer the issues in this study. The findings of this study shall serve as additional elements in the process of selecting and placing Principals, as well as be developed as a guide for educational administrators desiring effective and quality leadership orientation for managing and administrating schools in Sabah. This study is of importance as it contributes additional knowledge in the fields of education and human resource for the benefit of other researchers

Key Attributes of Graduate Interim’s Capabilities For successful Transfer Knowledge: a Structural Equation Modelling Using Partial Least Squares

A spirit of collaborative partnership amongst universities, industries, and communities is a prerequisite for a success of knowledge transfer program initiatives. The effort provides a platform for exchange of ideas either tangible or intangible, expertise, explicit or implicit knowledge and skills amongst parties involved. Companies are now beginning to recognize the fundamental value of knowledge transfer mechanism on how it is acquired, used and shared which contribute to their core competencies and in making sound strategic decisions to maintain the competitive advantage in today’s business environment. As to promote the ideas of knowledge transfer, the Ministry of Education (MOE) Malaysia has underlined the graduate intern’s capability as one of the areas under the critical agenda which need to be addressed in portraying the success of the knowledge transfer programme (KTP). Therefore, in order to obtain deeper insights of the issue, this project attempts to examine the contribution of graduate intern capabilities towards the success of KTP project in Malaysia. This study has employed a questionnaire that has been distributed to academics in the public universities in Malaysia who have obtained KTP grants from the government. The study has revealed that graduate interns’ capabilities contribute significantly to the implementation of knowledge transfer projects. Thus, higher education institutions must then address and review its present teaching and learning delivery to enhance students’ capabilities in dealing with the industry as well as with community

Persistent fluctuations in stride intervals under fractal auditory stimulation

Copyright @ 2014 Marmelat et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Stride sequences of healthy gait are characterized by persistent long-range correlations, which become anti-persistent in the presence of an isochronous metronome. The latter phenomenon is of particular interest because auditory cueing is generally considered to reduce stride variability and may hence be beneficial for stabilizing gait. Complex systems tend to match their correlation structure when synchronizing. In gait training, can one capitalize on this tendency by using a fractal metronome rather than an isochronous one? We examined whether auditory cues with fractal variations in inter-beat intervals yield similar fractal inter-stride interval variability as isochronous auditory cueing in two complementary experiments. In Experiment 1, participants walked on a treadmill while being paced by either an isochronous or a fractal metronome with different variation strengths between beats in order to test whether participants managed to synchronize with a fractal metronome and to determine the necessary amount of variability for participants to switch from anti-persistent to persistent inter-stride intervals. Participants did synchronize with the metronome despite its fractal randomness. The corresponding coefficient of variation of inter-beat intervals was fixed in Experiment 2, in which participants walked on a treadmill while being paced by non-isochronous metronomes with different scaling exponents. As expected, inter-stride intervals showed persistent correlations similar to self-paced walking only when cueing contained persistent correlations. Our results open up a new window to optimize rhythmic auditory cueing for gait stabilization by integrating fractal fluctuations in the inter-beat intervals.Commission of the European Community and the Netherlands Organisation for Scientific Research

How many people have had a myocardial infarction? Prevalence estimated using historical hospital data

<p>Abstract</p> <p>Background</p> <p>Health administrative data are increasingly used to examine disease occurrence. However, health administrative data are typically available for a limited number of years – posing challenges for estimating disease prevalence and incidence. The objective of this study is to estimate the prevalence of people previously hospitalized with an acute myocardial infarction (AMI) using 17 years of hospital data and to create a registry of people with myocardial infarction.</p> <p>Methods</p> <p>Myocardial infarction prevalence in Ontario 2004 was estimated using four methods: 1) observed hospital admissions from 1988 to 2004; 2) observed (1988 to 2004) and extrapolated unobserved events (prior to 1988) using a "back tracing" method using Poisson models; 3) DisMod incidence-prevalence-mortality model; 4) self-reported heart disease from the population-based Canadian Community Health Survey (CCHS) in 2000/2001. Individual respondents of the CCHS were individually linked to hospital discharge records to examine the agreement between self-report and hospital AMI admission.</p> <p>Results</p> <p>170,061 Ontario residents who were alive on March 31, 2004, and over age 20 years survived an AMI hospital admission between 1988 to 2004 (cumulative incidence 1.8%). This estimate increased to 2.03% (95% CI 2.01 to 2.05) after adding extrapolated cases that likely occurred before 1988. The estimated prevalence appeared stable with 5 to 10 years of historic hospital data. All 17 years of data were needed to create a reasonably complete registry (90% of estimated prevalent cases). The estimated prevalence using both DisMod and self-reported "heart attack" was higher (2.5% and 2.7% respectively). There was poor agreement between self-reported "heart attack" and the likelihood of having an observed AMI admission (sensitivity = 63.5%, positive predictive value = 54.3%).</p> <p>Conclusion</p> <p>Estimating myocardial infarction prevalence using a limited number of years of hospital data is feasible, and validity increases when unobserved events are added to observed events. The "back tracing" method is simple, reliable, and produces a myocardial infarction registry with high estimated "completeness" for jurisdictions with linked hospital data.</p

STUDY ON NUTRITIONAL AND ELEMENTAL ANALYSIS OF THE SEAWEEDS OF NORTHERN SAMAR, PHILIPINES

The purpose of the study: In this work, the nutritional and elemental analysis of seaweeds in Northern Samar is analyzed. Methodology: The seaweeds of Northern Samar are collected from the intertidal zone, and it was brought back to the College of Science for taxonomic identity.&nbsp;&nbsp; The nutritional and elemental content of the seaweeds were determined. Main findings: Based on the results obtained a total of 39 species belonging to eighteen (18) families of seaweeds were recorded from different coastal towns in Northern Samar, Philippines.&nbsp; The results revealed that for seaweeds with the economic value the nutritional and elemental content is comparable to the unknown seaweeds with no economic value.&nbsp;&nbsp;&nbsp;&nbsp; Implications: The results of the bioavailability of nutrients of this study might be the basis that unknown seaweeds with no economic value can be used directly in the diet and promote health advantage. Originality/Novelty of study: The seaweeds of Northern Samar are not properly documented in comparison with other marine flora.&nbsp; The results demonstrated that some species of seaweeds collected in Northern Samar with no economic value could also accumulate non-essential elements.&nbsp; Further studies would surely be a great contribution to our local food and pharmaceutical industries.&nbsp

On the Importance of Countergradients for the Development of Retinotopy: Insights from a Generalised Gierer Model

During the development of the topographic map from vertebrate retina to superior colliculus (SC), EphA receptors are expressed in a gradient along the nasotemporal retinal axis. Their ligands, ephrin-As, are expressed in a gradient along the rostrocaudal axis of the SC. Countergradients of ephrin-As in the retina and EphAs in the SC are also expressed. Disruption of any of these gradients leads to mapping errors. Gierer's (1981) model, which uses well-matched pairs of gradients and countergradients to establish the mapping, can account for the formation of wild type maps, but not the double maps found in EphA knock-in experiments. I show that these maps can be explained by models, such as Gierer's (1983), which have gradients and no countergradients, together with a powerful compensatory mechanism that helps to distribute connections evenly over the target region. However, this type of model cannot explain mapping errors found when the countergradients are knocked out partially. I examine the relative importance of countergradients as against compensatory mechanisms by generalising Gierer's (1983) model so that the strength of compensation is adjustable. Either matching gradients and countergradients alone or poorly matching gradients and countergradients together with a strong compensatory mechanism are sufficient to establish an ordered mapping. With a weaker compensatory mechanism, gradients without countergradients lead to a poorer map, but the addition of countergradients improves the mapping. This model produces the double maps in simulated EphA knock-in experiments and a map consistent with the Math5 knock-out phenotype. Simulations of a set of phenotypes from the literature substantiate the finding that countergradients and compensation can be traded off against each other to give similar maps. I conclude that a successful model of retinotopy should contain countergradients and some form of compensation mechanism, but not in the strong form put forward by Gierer

End-to-end 6-DoF Object Pose Estimation through Differentiable Rasterization

Here we introduce an approximated differentiable renderer to refine a 6-DoF pose prediction using only 2D alignment information. To this end, a two-branched convolutional encoder network is employed to jointly estimate the object class and its 6-DoF pose in the scene. We then propose a new formulation of an approximated differentiable renderer to re-project the 3D object on the image according to its predicted pose; in this way the alignment error between the observed and the re-projected object silhouette can be measured. Since the renderer is differentiable, it is possible to back-propagate through it to correct the estimated pose at test time in an online learning fashion. Eventually we show how to leverage the classification branch to profitably re-project a representative model of the predicted class (i.e. a medoid) instead. Each object in the scene is processed independently and novel viewpoints in which both objects arrangement and mutual pose are preserved can be rendered.
