The Researcher Librarian Partnership : building a culture of research

Increasingly, the library and information science (LIS) practitioner is being challenged to incorporate research into the context of their professional work. This paper reports on the Researcher-Librarian Partnership, a research-mentoring program that was initiated by the International Federation of the Library Association and Institutions. Six new LIS practitioners within their first seven years of professional practice took part in the program. Each was partnered with an experienced LIS researcher who provided mentoring and support. During the 12-month program the new professionals designed and implemented a research project on a topic of interest. This paper outlines the details of the program providing observations on how research mentoring can be a powerful way to ensure all stakeholders – practitioners, educators and professional associations – can plan an active role in supporting the development of a research culture within the profession.

Information Experience : New Perspectives and Research Directions

In this closing chapter the editors review key themes that have emerged through the book. We recognize the varied and dynamic nature of information experience across multiple contexts, and present our own conceptualization of information experience. Finally, we consider possible future directions for information experience research.

Who are Australia’s information educators?

In recent years there has been considerable discussion afforded to the challenges facing the future of information education in Australia. This paper reports a study that explored the characteristics and experiences of Australia’s information educators. The study was undertaken as part of a larger project, which was designed to establish a consolidated and holistic picture of the Australian information profession, and identify how its future education could be mediated in a cohesive and sustainable manner. Sixty-nine of Australia’s information educators completed an online questionnaire that gathered data on aspects such as age, gender, rank, qualifications, work activities, and job satisfaction. The key findings from this study confirm that a number of pressing issues are confronting information educators in Australia. For example, Australia’s information educators are considerably older than that the total Australian academic workforce; over half the information educators who participated in the study are looking to retire in the next ten years; and, Australia’s information educators spend more time on service activities then other disciplines within Australia’s education system and are place a stronger importance on teaching over research. Left unaddressed these issues will have significant implications for the future of information education as well as the broader information profession. Many of the key observations drawn from this study may also have relevance to other disciplines in the Australian educational context.

Education for Australia’s information future

Digital disruption and an increasingly networked society drive rapid change in many professions and a corresponding need for change in tertiary education. Across the world, information education has, to date, prepared graduates for employment in discrete professions, such as librarianship, records management, archives, and teacher librarianship. However, contemporary information practices are less defined and are demanding of new professional skill-sets and understandings. This paper reports a study that consulted Australia’s tertiary academics about the current circumstances of information education in the academy and elicited a vision and a concern for future directions in Australian information education.

Information Experience : Contemporary Perspectives

The purpose of this book is to open a conversation on the idea of information experience, which we understand to be a complex, multidimensional engagement with information. In developing the book we invited colleagues to propose a chapter on any aspect of information experience, for example conceptual, methodological or empirical. We invited them to express their interpretation of information experience, to contribute to the development of this concept. The book has thus become a vehicle for interested researchers and practitioners to explore their thinking around information experience, including relationships between information experience, learning experience, user experience and similar constructs. It represents a collective awareness of information experience in contemporary research and practice. Through this sharing of multiple perspectives, our insights into possible ways of interpreting information experience, and its relationship to other concepts in information research and practice, is enhanced. In this chapter, we introduce the idea of information experience. We also outline the book and its chapters, and bring together some emerging alternative views and approaches to this important idea.

Diversifying Information Literacy Research : An Informed Learning Perspective

This article uses the idea of informed learning, an interpretation of information literacy that focuses on people’s information experiences rather than their skills or attributes, to analyse the character of using information to learn in diverse communities and settings, including digital, faith, indigenous and ethnic communities. While researchers of information behaviour or information seeking and use have investigated people’s information worlds in diverse contexts, this work is still at its earliest stages in the information literacy domain. To date, information literacy research has largely occurred in what might be considered mainstream educational and workplace contexts, with some emerging work in community settings. These have been mostly in academic libraries, schools and government workplaces. What does information literacy look like beyond these environments? How might we understand the experience of effective information use in a range of community settings, from the perspective of empirical research and other sources? The article concludes by commenting on the significance of diversifying the range of information experience contexts, for information literacy research and professional practice.

Greenhouse gas emissions in livestock production systems

Agriculture is responsible for a significant proportion of total anthropogenic greenhouse gas emissions (perhaps 18% globally), and therefore has the potential to contribute to efforts to reduce emissions as a means of minimising the risk of dangerous climate change. The largest contributions to emissions are attributed to ruminant methane production and nitrous oxide from animal waste and fertilised soils. Further, livestock, including ruminants, are an important component of global and Australian food production and there is a growing demand for animal protein sources. At the same time as governments and the community strengthen objectives to reduce greenhouse gas emissions, there are growing concerns about global food security. This paper provides an overview of a number of options for reducing methane and nitrous oxide emissions from ruminant production systems in Australia, while maintaining productivity to contribute to both objectives. Options include strategies for feed modification, animal breeding and herd management, rumen manipulation and animal waste and fertiliser management. Using currently available strategies, some reductions in emissions can be achieved, but practical commercially available techniques for significant reductions in methane emissions, particularly from extensive livestock production systems, will require greater time and resource investment. Decreases in the levels of emissions from these ruminant systems (i.e., the amount of emissions per unit of product such as meat) have already been achieved. However, the technology has not yet been developed for eliminating production of methane from the rumen of cattle and sheep digesting the cellulose and lignin-rich grasses that make up a large part of the diet of animals grazing natural pastures, particularly in arid and semi-arid grazing lands. Nevertheless, the abatement that can be achieved will contribute significantly towards reaching greenhouse gas emissions reduction targets and research will achieve further advances.

Experiences of informed learning in the undergraduate classroom

This chapter discusses using phenomenography to study information experience. Phenomenographers aim to investigate people’s experiences of the world around them, which is comprised of the interrelationship between an individual and a phenomenon they are focusing on. Phenomenography has been identified as a research approach suited to the study of information experience. Phenomenographic research investigating experiences of using information in different contexts has led to the development of informed learning, which is an approach to information literacy that emphasizes learning as an outcome of using information. Recent research focusing on information experience has been referred to as informed learning research. The preliminary findings from a current informed learning study illustrate the educative benefits of researching information experience. This study investigates a classroom lesson, in which a teacher outlines an assignment that requires the students to understand a language and gender topic by investigating the evolution of research on the topic. The lesson is experienced in multiple ways by the students and the analysis suggests a way of enhancing the lesson to enable more students to experience it in the way intended by the teacher.

Ectopic overexpression of a mungbean vacuolar Na+/H+ antiporter gene (VrNHX1) leads to increased salinity stress tolerance in transgenic Vigna unguiculata L. Walp

Salinity is a major threat to sustainable agriculture worldwide. Plant NHX exchangers play an important role in conferring salt tolerance under salinity stress. In this study, a vacuolar Na+/H+ antiporter gene VrNHX1 (Genbank Accession No. JN656211.1) from mungbean (Vigna radiata) was introduced into cowpea (Vigna unguiculata) by the Agrobacterium tumefaciens-mediated transformation method. Polymerase chain reaction and Southern blot hybridization confirmed the stable integration of VrNHX1 into the cowpea genome. Comparative expression analysis by semi-quantitative RT-PCR revealed higher expression of VrNHX1 in transgenic cowpea plants than wild-type. Under salt stress conditions, T2 transgenic 35S:VrNHX1 cowpea lines exhibited higher tolerance to 200 mM NaCl treatment than wild-type. Furthermore, T2 transgenic 35S:VrNHX1 lines maintained a higher K+/Na+ ratio in the aerial parts under salt stress and accumulated higher [Na+] in roots than wild-type. Physiological analysis revealed lower levels of lipid peroxidation, hydrogen peroxide and oxygen radical production but higher levels of relative water content and proline, ascorbate and chlorophyll contents in T2 transgenic 35S:VrNHX1 lines.

Health information literacy and ageing Australians : applications for practice

This practice framework is designed for health practitioners and allied health care workers. The framework provides empirically-based descriptions of ageing Australians’ experiences of health information literacy and suggests how these may provide a foundation for helping ageing Australians enhance their health information literacy. Health information literacy is understood here to be people’s use of relevant information to learn about health.

Researching information experience : methodological approaches

This chapter highlights the varied scope of research in the emerging information experience domain. First, I share my perspective as educator-researcher on information experience and its association with informed learning. Then, in six methodological snapshots I present a selection of qualitative approaches which are suited to investigating information experience. The snapshots feature: action research, constructivist grounded theory, ethnomethodology, expanded critical incident approach, phenomenography and qualitative case study. By way of illustration, six researchers explain how and why they use one of these methods. Finally, I review the key characteristics of the six methods and their respective benefits for information experience research.

Addressing factory needs in cane variety selection

Cane fibre content has increased over the past ten years. Some of that increase can be attributed to new varieties selected for release. This paper reviews the existing methods for quantifying the fibre characteristics of a variety, including fibre content and fibre quality measurements – shear strength, impact resistance and short fibre content. The variety selection process is presented and it is reported that fibre content has zero weighting in the current selection index. An updated variety selection approach is proposed, potentially replacing the existing selection process relating to fibre. This alternative approach involves the use of a more complex mill area level model that accounts for harvesting, transport and processing equipment, taking into account capacity, efficiency and operational impacts, along with the end use for the bagasse. The approach will ultimately determine a net economic value for the variety. The methodology lends itself to a determination of the fibre properties that have a significant impact on the economic value so that variety tests can better target the critical properties. A low-pressure compression test is proposed as a good test to provide an assessment of the impact of a variety on milling capacity. NIR methodology is proposed as a technology to lead to a more rapid assessment of fibre properties, and hence the opportunity to more comprehensively test for fibre impacts at an earlier stage of variety development.

The expert searcher's experience of information

Expert searchers engage with information in a variety of professional settings, as information brokers, reference librarians, information architects and faculty who teach advanced searching. As my recent research shows, the expert searcher’s information experience is defined by profound discernment of critical concepts about information, and a fluid ability to apply this knowledge to their engagement with the information environment. The information experience of the expert searcher means active and intentional participation with the processes and players that created that information environment. Expert searchers become an integral and seamless part of their information environment and also play a role in facilitating the information experiences of others. In this chapter, after discussing my understanding of the concept of information experience, I outline how I used threshold concept theory to explore the information experience of expert searchers. Through the findings, I identify four threshold concepts in the acquisition of search expertise that provide new perspectives on the information experience of the expert searcher. These new perspectives have implications for search engine design and how advanced search skills are taught. Finally, I consider how the fresh insights about the expert searcher’s experiences contribute to wider understanding about information experience.

The plasticity of NBS resistance genes in sorghum is driven by multiple evolutionary processes

Background Increased disease resistance is a key target of cereal breeding programs, with disease outbreaks continuing to threaten global food production, particularly in Africa. Of the disease resistance gene families, the nucleotide-binding site plus leucine-rich repeat (NBS-LRR) family is the most prevalent and ancient and is also one of the largest gene families known in plants. The sequence diversity in NBS-encoding genes was explored in sorghum, a critical food staple in Africa, with comparisons to rice and maize and with comparisons to fungal pathogen resistance QTL. Results In sorghum, NBS-encoding genes had significantly higher diversity in comparison to non NBS-encoding genes and were significantly enriched in regions of the genome under purifying and balancing selection, both through domestication and improvement. Ancestral genes, pre-dating species divergence, were more abundant in regions with signatures of selection than in regions not under selection. Sorghum NBS-encoding genes were also significantly enriched in the regions of the genome containing fungal pathogen disease resistance QTL; with the diversity of the NBS-encoding genes influenced by the type of co-locating biotic stress resistance QTL. Conclusions NBS-encoding genes are under strong selection pressure in sorghum, through the contrasting evolutionary processes of purifying and balancing selection. Such contrasting evolutionary processes have impacted ancestral genes more than species-specific genes. Fungal disease resistance hot-spots in the genome, with resistance against multiple pathogens, provides further insight into the mechanisms that cereals use in the “arms race” with rapidly evolving pathogens in addition to providing plant breeders with selection targets for fast-tracking the development of high performing varieties with more durable pathogen resistance.

The biology of an isolated population of American Flamingo Phoenicopterus ruber in the Galapagos Islands

A genetically and morphologically divergent population of c.500 American Flamingos, isolated from the parental Caribbean stock of Phoenicopterus ruber, occurs in the Galapagos archipelago. Based primarily on data from a 3-year study, we provide the first description of the feeding and breeding biology of this population. Galapagos provides a suitable habitat comprising lagoons on a number of islands, among which the flamingos travel in response to food and nest site availability. The occurrence and qualnity of some food species was associated with the chlorosity of lagoon water, as was the distribution of flamingos. They bred opportunistically at five lagoons on four islands, sometimes simultaneously on more than one island. Group display usually involved approx 20 birds and colonies contained as few as three nests. Laying occurred during nine months of the year... We review potential dangers to this unique population and suggest conservation measures.
