Adapting to new challenges: extension theory and practice for the 21st century

Twenty first century challenges facing agriculture include climate change, threats to food security for a growing population and downward economic pressures on rural livelihoods. Addressing these challenges will require innovation in extension theory, policy and education, at a time when the dominance of the state in the provision of knowledge and information services to farmers and rural entrepreneurs continues to decline. This paper suggests that extension theory is catching up with and helping us to understand innovative extension practice, and therefore provides a platform for improving rural development policies and strategies. Innovation is now less likely to be spoken of as something to be passed on to farmers, than as a continuing process of creativity and adaptation that can be nurtured and sustained. Innovation systems and innovation platforms are concepts that recognise the multiple factors that lead to farmers’ developing, adapting and applying new ideas and the importance of linking all actors in the value chain to ensure producers can access appropriate information and advice for decision making at all stages in the production process. Concepts of social learning, group development and solidarity, social capital, collective action and empowerment all help to explain and therefore to apply more effectively group extension approaches in building confidence and sustaining innovation. A challenge facing educators is to ensure the curricula for aspiring extension professionals in our higher education institutions are regularly reviewed and keep up with current and future developments in theory, policy and practice.

Pollination ecology in the 21st century: key questions for future research

To inspire new ideas in research on pollination ecology, we list the most important unanswered questions in the field. This list was drawn up by contacting 170 scientists from different areas of pollination ecology and asking them to contribute their opinion on the greatest knowledge gaps that need to be addressed. Almost 40% of them took part in our email poll and we received more than 650 questions and comments, which we classified into different categories representing various aspects of pollination research. The original questions were merged and synthesised, and a final vote and ranking led to the resultant list. The categories cover plant sexual reproduction, pollen and stigma biology, abiotic pollination, evolution of animal-mediated pollination, interactions of pollinators and floral antagonists, pollinator behaviour, taxonomy, plant-pollinator assemblages, geographical trends in diversity, drivers of pollinator loss, ecosystem services, management of pollination, and conservation issues such as the implementation of pollinator conservation. We focused on questions that were of a broad scope rather than case-specific; thus, addressing some questions may not be feasible within single research projects but constitute a general guide for future directions. With this compilation we hope to raise awareness of pollination-related topics not only among researchers but also among non-specialists including policy makers, funding agencies and the public at large.

Comment on "Tropospheric temperature response to stratospheric ozone recovery in the 21st century" by Hu et al. (2011)

Abstract. In a recent paper Hu et al. (2011) suggest that the recovery of stratospheric ozone during the first half of this century will significantly enhance free tropospheric and surface warming caused by the anthropogenic increase of greenhouse gases, with the effects being most pronounced in Northern Hemisphere middle and high latitudes. These surprising results are based on a multi-model analysis of CMIP3 model simulations with and without prescribed stratospheric ozone recovery. Hu et al. suggest that in order to properly quantify the tropospheric and surface temperature response to stratospheric ozone recovery, it is necessary to run coupled atmosphere-ocean climate models with stratospheric ozone chemistry. The results of such an experiment are presented here, using a state-of-the-art chemistry-climate model coupled to a three-dimensional ocean model. In contrast to Hu et al., we find a much smaller Northern Hemisphere tropospheric temperature response to ozone recovery, which is of opposite sign. We suggest that their result is an artifact of the incomplete removal of the large effect of greenhouse gas warming between the two different sets of models.

Changes in subduction in the South Atlantic Ocean during the 21st century in the CCSM3

The Community Climate System Model version 3 is used to analyse changes in water mass subduction rates in the South Atlantic Ocean over the 21st century. The model results are first compared to observations over 1950-2000, and shown to be rather good. The subduction rates do not change significantly over the 21st century, but the densities at which water masses form become significantly lighter. The strong westerly winds in this region do not change much, which suggests small changes to the rate at which the Atlantic sector of the Southern Ocean takes up heat and carbon dioxide over the 21st century.

Veterinary Medical Libraries in the 21st Century

The purpose of this volume is to present a picture of information access and delivery by United States and Canadian academic veterinary medical libraries (VMLs) to the veterinary community and others with interests in the profession. This is done by discussing the resources that are available, as well as methods of delivery of that information. Our discussion of these topics will not only point out the unique aspects of these collections and services, but will also illustrate much that is in common with all medical collections and library services. As with all libraries, the goal of VMLs is to provide high quality service while looking after the information needs of their clientele through selection, acquisition, cataloging, and dissemination of materials and familiarizing their users with these resources. In the past decade, new challenges and opportunities for information specialists stem from the impact of technology on VMLs. Our goal with this volume is to be concise, but thorough about all of these topics.

The Healthy Workplace of the 21st Century: The Benefit of Organizational Wellness Programs on Employee Health and Absenteeism

Every year, obesity rates continue to rise and have reached epidemic proportions throughout the United States. The costs associated with obesity are staggering and many researchers feel that the workplace should be the new front line in the battle for a healthier workforce. Employers must take action to address this worsening health crisis and help reduce spiraling medical costs and absenteeism rates. This capstone reviews the current literature on wellness programs and discusses different companies' approaches to wellness programs that have special emphasis on nutrition and physical activity. It also provides strategies and recommendations for companies eager to initiate a comprehensive, dynamic and directed wellness program to improve the current and future health of their workforce.

RELIGIOUS SCULPTURE OF THE CHILOÉ ARCHIPELAGO, FROM THE 17TH TO THE 21ST CENTURY

Despite its central role in religious life of the region, the sculptural tradition of the Southern Chilean Chiloé Archipelago, ranging from the 17th century to the present day, has been vastly understudied. Isidoro Vázquez de Acuña’s 1994 volume Santeria de Chiloe: ensayo y catastro remains the only catalogue of Chilote sculpture. Though the author includes photographs of a vast array of works, he does not attempt to place the sculptures within a chronology, or consider their place within the greater Latin American context. My thesis will place this group of works within a chronological and geographical context that reaches from the 16th century to the present day, connected to the artistic traditions of regions as far afield as Paraguay and Lima. I will first consider the works brought to the Archipelago by religious orders – the Jesuits and Franciscans – as well as influences on artistic style and religious culture throughout the 17th, 18th and 19th centuries. I will focus in particular on three works generally considered to be from the 17th and 18th centuries – the Virgin of Loreto at Achao, the Saint Michael at Castro, and the Jesus Nazareno of Caguach – using visual analysis and sifting through generations of primary and secondary sources to determine from where and when these sculptures came. With this investigation as a foundation, I will consider how they inspired vernacular sculptural expression and trace ‘family trees’ of vernacular works based on these precedents. Vernacular artistic traditions are often viewed as derivative and lacking in skill, but Chilote sculptors in fact engaged with a variety of outside influences and experimented with different sculptural styles. I will conclude by considering which aspects of these styles Chilote artists chose to incorporate into their own work, alter or exclude, artistic decisions that shed light on the Archipelago’s religious and cultural fabric.

Ageing Modernity: Growing old in the EU in the 21st Century. EU Centre in Singapore Background Brief No. 7, December 2012

How do urban growth and an ageing population affect or inform planning at the national and regional level in the European Union? At a time when economic stagnation, environmental concerns and demographic changes are affecting social and political discourses, they are also influencing urban form and development. Furthermore, as people are living longer, they still have much to contribute in their later years to their communities and to the economy. As a result, the policy and urban design paradigm is shifting as the relative importance of older people grows. By looking at the connections between ageing, design and the environment, and the role of policy and planning strategies, this brief seeks to understand how the EU plans for an ageing population and attempts to reshape communities in an increasingly challenging socioeconomic context. This brief looks at some of the regional initiatives and guidelines and highlights the role the EU is playing in influencing some of the development trends, particularly those in urban centres.
