Economic growth in low income countries: How the G20 can help to raise and sustain it
No full textThis paper aims to operationalise the G20 commitment to ensure that the benefits of global growth are shared with Low Income Countries. Growth is central to poverty reduction and the achievement of MDGs, and in developing countries it is episodic and volatile. However, while the current LICs have poor growth histories, the countries that started off the 1960s as LICs have had virtually the same average growth rates as other country groups. We review the evidence connecting long-run growth and growth accelerations and collapses to six areas of policy: trade, skills development, macro-stability, financial development, infrastructure investment and human development. Growth strategies have to be developed and owned by LIC governments and societies and they need to be tailored to individual country needs. However, there are some things which the G20 can do to help. We group these actions under three headings: mitigating downturns, boosting underlying growth rates and developing institutions and knowledge. A final annex describes how Korea’s spectacular growth strategy can be viewed through these lenses.growth, low income countries, G20

The people behind the papers – Jason Ko and Daniel Lobo
No full textPlanarians grow when they are fed and shrink during periods of starvation. However, it is unclear how they maintain appropriate body proportions as their size changes. A new paper in Development investigates the differences between growth and shrinkage dynamics and builds a mathematical model to explore the mechanisms underpinning these two processes. To learn more about the story behind the paper, we caught up with first author, Jason Ko, and corresponding author, Daniel Lobo, Associate Professor at the University of Maryland.https://doi.org/10.1242/dev.20298
Organizational Learning and Marketing Capability Development: A Study of Charity Retailing Operation of British Social Enterprises
No full textSocial enterprise is a hybrid form of profit- and social benefit-seeking organization whereby traditional nonprofit organizations pursue both their social mission and business opportunities. To embrace this new strategic direction shift, the nonprofit organizations need to develop new competences that will enable them to respond to the changes in the business model. The article investigates the learning mechanisms through which social enterprises develop a marketing capability to deploy their resources in the marketplace as the drivers of competitive advantage in their commercial practice. We study eight cases of UK-based charity retailers, in order to address the role of knowledge accumulation, articulation and codification process in the evolution of marketing capability development. We identify, amongst other things that the critical process of organizational learning for social enterprise is to transfer the experience into organization specific knowledge under the social aspects of constraints
Immobilization of Antibody on a Cyclic Olefin Copolymer Surface with Functionalizable, Non-Biofouling Poly[Oligo(Ethylene Glycol) Methacrylate]
No full textWe report a perfluoroaryl azide-based photoreaction for synthesizing functionalizable and nonbiofouling poly[oligo(ethylene glycol) methacrylate] (pOEGMA) films on a chemically inert COC substrate, and an estimation of a surface coverage of the antibody immobilized onto the surface with the immuno-gold nanoparticles. The processes were confirmed by water contact angle measurement, FT-IA spectroscopy, and FE-SEM. The strategy demonstrated in this work could be applied to functionalizations of other polymeric materials and determination of the binding capacity of analytes in biosensors and microfluidic devices
Ko au te whenua, te whenua ko au – I am the land, the land is me: An autoethnographic investigation of a secondary school teacher’s experience seeking to enrich learning in outdoor education for Māori students.
No full textThis thesis is my story as an outdoor educator, as a researcher, and a co-participant reflecting on my own actions and experiences as well as those of my students. In this autoethnography I share my revelations and tensions in my role as an outdoor education teacher seeking to enrich the experiences of Māori students. Māori culture and history have largely been ignored in the outdoor education classrooms and environments of Aotearoa New Zealand. After teaching the subject for ten years I didn’t perceive that I was perpetuating the same invisibility in my own outdoor education course. Over this time a number of questions that had fermented at the back of my mind came to the fore; ‘why are so few Māori students opting to take outdoor education as a senior secondary school subject?’ and ‘how can I make the subject of outdoor education more desirable and appealing to Māori?’ A place-responsive approach incorporates and values traditional ways of learning through the notion of place and the stories attached to them. The cultural context of learning about and through place has the potential to provide learning opportunities that are relevant and meaningful to all learners but particularly Māori. Place-responsive pedagogies allow outdoor educators to create an environment where language, knowledge, culture and values are normal, valid and legitimate – contexts where Māori students can be themselves. Through this research I have found that the implementation of a place responsive approach has had significant implications for Year twelve outdoor education at Mount Maunganui College. The improvement in Māori student achievement and numbers selecting the subject have been affirming.

Parametric study on the flight envelope of a radio-frequency ion thruster based atmosphere-breathing electric propulsion system
No full textThe atmosphere-breathing electric propulsion (ABEP) system utilizes atmospheric species as propellants to generate thrust for drag compensation of a satellite in very-low-Earth-orbit (VLEO). A parametric approach is used to assess the impact of different parameters on the flight envelope of a sample VLEO satellite with an ABEP system based on a radio-frequency ion thruster (RIT). The considered parameters include capture efficiency, maximum input power, solar activity, and atomic oxygen recombination factor. The NRLMSIS 2.0 atmosphere model is used to determine the flow conditions at VLEO, at a target altitude of 150–300 km with high, moderate, and low solar activity levels. DSMC method is employed to calculate the drag of the sample satellite with the ABEP system. The 0-D model of the RIT discharge chamber is used to predict the thrust of the RIT-based ABEP system. The flight envelope of a sample RIT-based ABEP system shows that drag can be compensated at altitudes between 196 km and 248 km. Increasing capture efficiency and maximum input power expands the feasible range for drag compensation to higher and lower altitudes, respectively. Also, the flight envelope shifts to higher altitudes with increasing solar activity levels. However, the atomic oxygen recombination factor of the intake device has minimal effects on the flight envelope.
KNOWLEDGE ACCUMULATION IN ASIAN PUBLIC ADMINISTRATION RESEARCH: A CRITICAL REVIEW
No full textGiven the growing controversy over the relevance of Anglo-Saxon style public administration to developing countries and a greater demand for more context-relevant theories of public administration in Asia, we should expect that Asian scholars achieve a certain level of knowledge growth in line with this controversy and demand. On the basis of the review of 8810 articles published in nine major international journals during 1990-2011, the author found that the number of articles on Asian public administration is very small, and there is no strong pattern of growth in this regard. In addition, there are very few studies adopting a comparative approach covering multiple Asian countries. Copyright (c) 2013 John Wiley & Sons, Ltd.N

Differentially altered social dominance- and cooperative-like behaviors in Shank2- and Shank3-mutant mice
No full textBackground: Recent progress in genomics has contributed to the identification of a large number of autism spectrum disorder (ASD) risk genes, many of which encode synaptic proteins. Our understanding of ASDs has advanced rapidly, partly owing to the development of numerous animal models. Extensive characterizations using a variety of behavioral batteries that analyze social behaviors have shown that a subset of engineered mice that model mutations in genes encoding Shanks, a family of excitatory postsynaptic scaffolding proteins, exhibit autism-like behaviors. Although these behavioral assays have been useful in identifying deficits in simple social behaviors, alterations in complex social behaviors remain largely untested. Methods: Two syndromic ASD mouse models—Shank2 constitutive knockout [KO] mice and Shank3 constitutive KO mice—were examined for alterations in social dominance and social cooperative behaviors using tube tests and automated cooperation tests. Upon naïve and salient behavioral experience, expression levels of c-Fos were analyzed as a proxy for neural activity across diverse brain areas, including the medial prefrontal cortex (mPFC) and a number of subcortical structures. Findings: As previously reported, Shank2 KO mice showed deficits in sociability, with intact social recognition memory, whereas Shank3 KO mice displayed no overt phenotypes. Strikingly, the two Shank KO mouse models exhibited diametrically opposed alterations in social dominance and cooperative behaviors. After a specific social behavioral experience, Shank mutant mice exhibited distinct changes in number of c-Fos+ neurons in the number of cortical and subcortical brain regions. Conclusions: Our results underscore the heterogeneity of social behavioral alterations in different ASD mouse models and highlight the utility of testing complex social behaviors in validating neurodevelopmental and neuropsychiatric disorder models. In addition, neural activities at distinct brain regions are likely collectively involved in eliciting complex social behaviors, which are differentially altered in ASD mouse models. © 2020, The Author(s).1
