Building synergies in development research: The application of the mosaic model to animal health research

Development research has responded to a number of charges over the past few decades. For example, when traditional research was accused of being 'top-down', the response was participatory research, linking the 'receptors' to the generators of research. As participatory processes were recognised as producing limited outcomes, the demand-led agenda was born. In response to the alleged failure of research to deliver its products, the 'joined-up' model, which links research with the private sector, has become popular. However, using examples from animal-health research, this article demonstrates that all the aforementioned approaches are seriously limited in their attempts to generate outputs to address the multi-faceted problems facing the poor. The article outlines a new approach to research: the Mosaic Model. By combining different knowledge forms, and focusing on existing gaps, the model aims to bridge basic and applied findings to enhance the efficiency and value of research, past, present, and future.

Formation of triple helical nanofibers using self-assembling chiral benzene-1,3,5-tricarboxamides and reversal of the nanostructure's handedness using mirror image building blocks

Intertwining triple helical nanofibers with an overall handedness have been formed from self-assembling chiral benzene-1,3,5-tricarboxamides 1, 2 and 3, whereas the achiralbenzene-1,3,5-tricarboxamide 4 upon self-association gives rise to straight nanofibers without any twist and transmission electron microscopy images of chiral compounds clearly demonstrate that the handedness of the triple helical nanofibers can be reversed by using the enantiomeric benzene-1,3,5-tricarboxamide building blocks.

Multi-agent building control in shared environment

Multi-agent systems have been adopted to build intelligent environment in recent years. It was claimed that energy efficiency and occupants' comfort were the most important factors for evaluating the performance of modem work environment, and multi-agent systems presented a viable solution to handling the complexity of dynamic building environment. While previous research has made significant advance in some aspects, the proposed systems or models were often not applicable in a "shared environment". This paper introduces an ongoing project on multi-agent for building control, which aims to achieve both energy efficiency and occupants' comfort in a shared environment.

The tendering process and performance analysis of a public building project in Ghana

A case study on the tendering process and cost/time performance of a public building project in Ghana is conducted. Competitive bids submitted by five contractors for the project, in which contractors were required to prepare their own quantities, were analyzed to compare differences in their pricing levels and risk/requirement perceptions. Queries sent to the consultants at the tender stage were also analyzed to identify the significant areas of concern to contractors in relation to the tender documentation. The five bidding prices were significantly different. The queries submitted for clarifications were significantly different, although a few were similar. Using a before-and-after experiment, the expected cost/time estimate at the start of the project was compared to the actual cost/time values, i.e. what happened in the actual construction phase. The analysis showed that the project exceeded its expected cost by 18% and its planned time by 210%. Variations and inadequate design were the major reasons. Following an exploration of these issues, an alternative tendering mechanism is recommended to clients. A shift away from the conventional approach of awarding work based on price, and serious consideration of alternative procurement routes can help clients in Ghana obtain better value for money on their projects.

Building resilience in the face of recurring environmental crisis in African Sahel

The present food shortages in the Horn of Africa and the West African Sahel are affecting 31 million people. Such continuing and future crises require that people in the region adapt to an increasing and potentially irreversible global sustainability challenge. Given this situation and that short-term weather and seasonal climate forecasting have limited skill for West Africa, the Rainwatch project illustrates the value of near real-time monitoring and improved communication for the unfavourable 2011 West African monsoon, the resulting severe drought-induced humanitarian impacts continuing into 2012, and their exacerbation by flooding in 2012. Rainwatch is now coupled with a boundary organization (Africa Climate Exchange, AfClix) with the aim of integrating the expertise and actions of relevant institutions, agencies and stakeholders to broker ground-based dialogue to promote resilience in the face of recurring crisis.

Wind pressure on a single building immersed in a low-jet wind profile

This paper for the first time discuss the wind pressure distribution on the building surface immersed in wind profile of low-level jet rather than a logarithmic boundary-layer profile. Two types of building models are considered, low-rise and high-rise building, relative to the low-level jet height. CFD simulation is carried out. The simulation results show that the wind pressure distribution immersed in a low-jet wine profile is very different from the typical uniform and boundary-layer flow. For the low-rise building, the stagnation point is located at the upper level of windward façade for the low-level jet wind case, and the separation zone above the roof top is not as obvious as the uniform case. For the high-rise building model, the height of stagnation point is almost as high as the low-level jet height.

Building capacity in an indigenous nonprofit artistic enterprise

Growth in Indigenous artistic enterprises has attracted government funding, cultural tourists, and arts managers with a strong interest in cultural democracy and, more recently, an interest in business models for these artists. This paper documents a case study of Arilla Paper, an artistic enterprise in Queensland, Australia, where a group of Aboriginal women, worked on making paper from natural materials, to create a sustainable non-profit arts business. Sections of the business manual developed for these women, together with primary and secondary data supporting the Indigenous creative industries, are presented. The paper concludes that success in such ventures requires a social entrepreneurship model of funding that recognises the challenges of Indigenous cultural ownership and capacity building in business practice.

Permian brachiopods from the Baoshan and Simao Blocks in Western Yunnan, China

This paper describes and illustrates four Permian brachiopod assemblages (Assemblages A–D) from western Yunnan, southwest China. Assemblage A occurs in the basal part of the Yongde Formation in the Xiaoxinzhai section in the southern Baoshan Block and is assignable to the latest Artinskian or earliest Kungurian. Assemblage B occurs about 50 m stratigraphically above Assemblage A in the same section, and is of Chihsian (Kungurian–Roadian) age. Assemblage C was collected from the Yongde Formation in the Anpaitian section in the southern Baoshan Block and is most likely Roadian to Wordian in age. Assemblage D came from the Longtan Formation in the Simao Block and is of late Wuchiapingian in age. The brachiopod faunas from the Yongde Formation of the Baoshan Block, as a whole, is dominated by species characteristic of the Cathaysian Province, although some links with Peri-Gondwanan faunas are also evident. In contrast, Assemblage D from the Simao Block is characterised exclusively by taxa of the Cathaysian Province. New taxa described and illustrated are Neochonetes (Huangichonetes) inflatus n. sp. Costatumulus minor n. sp. and Celebetus yunnanensis n. sp.
