Software Engineering as Instrumentation for the Long Tail of Scientific Software

The vast majority of the long tail of scientific software, the myriads of tools that implement the many analysis and visualization methods for different scientific fields, is highly specialized, purpose-built for a research project, and has to rely on community uptake and reuse for its continued development and maintenance. Although uptake cannot be controlled over even guaranteed, some of the key factors that influence whether new users or developers decide to adopt an existing tool or start a new one are about how easy or difficult it is to use or enhance a tool for a purpose for which it was not originally designed. The science of software engineering has produced techniques and practices that would reduce or remove a variety of barriers to community uptake of software, but for a variety of reasons employing trained software engineers as part of the development of long tail scientific software has proven to be challenging. As a consequence, community uptake of long tail tools is often far more difficult than it would need to be, even though opportunities for reuse abound. We discuss likely reasons why employing software engineering in the long tail is challenging, and propose that many of those obstacles could be addressed in the form of a cross-cutting non-profit center of excellence that makes software engineering broadly accessible as a shared service, conceptually and in its effect similar to shared instrumentation.Comment: 4 page

Sustainable plant protection for increased food security in a changing climate

The global climate is changing. Rising temperatures in temperate regions are making headlines, but there are a host of changes that may have even greater impact on a global scale, particularly in regions where food security is already delicately balanced. Rising sea levels, changing patterns of rainfall, availability of water and increasing concentration of carbon dioxide in the atmosphere are all likely to affect the biotic environment upon which we depend

Ready for Tomorrow: Demand-Side Emerging Skills for the 21st Century

As part of the Ready for the Job demand-side skill assessment, the Heldrich Center explored emerging work skills that will affect New Jersey's workforce in the next three to five years. The Heldrich Center identified five specific areas likely to generate new skill demands: biotechnology, security, e-learning, e-commerce, and food/agribusiness. This report explores the study's findings and offers recommendations for improving education and training in New Jersey

Bio-techno-practice. Personal and social responsibility in the academic work

The new challenges posed by biomedicine and biotechnologies ask for a deeper consideration on the relationship among science, knowledge and social responsibility. On one hand, in fact, technologies seem to shape our idea of human progress and scientific understanding of the natural world and of life in particular. On the other hand, a thoughtful consideration on the philosophical foundations of science as human enterprise is required. This also opens important questions about the new emerging paradigms of ‘excellence’ in the academic, social and market fields and on the role that universities play in training the future leaders and professionals of our society. After a short review of the contemporary philosophical reflections on the unity of knowledge, which is the origin and the goal of academic work, we argue that adherence to our current challenges through the bio-techno-practice prism is a fecund driving force of the academic activities. Moving from the experience of an international project, we also discuss the impact that such interdisciplinary activities have on what we call hidden curriculum, i.e. the embodied style of (skills that allow) people in taking care of each other in their physical, social, professional and scientific needs

Information seeking retrieval, reading and storing behaviour of library users

In the interest of digital libraries, it is advisable that designers be aware of the potential behaviour of the users of such a system. There are two distinct parts under investigation, the interaction between traditional libraries involving the seeking and retrieval of relevant material, and the reading and storage behaviours ensuing. Through this analysis, the findings could be incorporated into digital library facilities. There has been copious amounts of research on information seeking leading to the development of behavioural models to describe the process. Often research on the information seeking practices of individuals is based on the task and field of study. The information seeking model, presented by Ellis et al. (1993), characterises the format of this study where it is used to compare various research on the information seeking practices of groups of people (from academics to professionals). It is found that, although researchers do make use of library facilities, they tend to rely heavily on their own collections and primarily use the library as a source for previously identified information, browsing and interloan. It was found that there are significant differences in user behaviour between the groups analysed. When looking at the reading and storage of material it was hard to draw conclusions, due to the lack of substantial research and information on the topic. However, through the use of reading strategies, a general idea on how readers behave can be developed. Designers of digital libraries can benefit from the guidelines presented here to better understand their audience
