AbstractNodulation is the result of a mutualistic interaction between legumes and symbiotic soil bacteria (e.g. soybean [Glycine max] and Bradyrhizobium japonicum) initiated by the infection of plant root hair cells by the symbiont. Fewer than 20 plant genes involved in the nodulation process have been functionally characterized. Considering the complexity of the symbiosis, significantly more genes are likely involved. To identify genes involved in root hair cell infection, we performed a large-scale transcriptome analysis of B. japonicum-inoculated and mock-inoculated soybean root hairs using three different technologies: microarray hybridization, Illumina sequencing, and quantitative real-time reverse transcription-polymerase chain reaction. Together, a total of 1,973 soybean genes were differentially expressed with high significance during root hair infection, including orthologs of previously characterized root hair infection-related genes such as NFR5 and NIN. The regulation of 60 genes was confirmed by quantitative real-time reverse transcription-polymerase chain reaction. Our analysis also highlighted changes in the expression pattern of some homeologous and tandemly duplicated soybean genes, supporting their rapid specialization.
Members of theLBDFamily of Transcription Factors Repress Anthocyanin Synthesis and Affect Additional Nitrogen Responses inArabidopsis

Published: November 2009

AbstractNitrogen (N) and nitrate (NO3 −) per se regulate many aspects of plant metabolism, growth, and development. N/NO3 − also suppresses parts of secondary metabolism, including anthocyanin synthesis. Molecular components for this repression are unknown. We report that three N/NO3 −-induced members of the LATERAL ORGAN BOUNDARY DOMAIN (LBD) gene family of transcription factors (LBD37, LBD38, and LBD39) act as negative regulators of anthocyanin biosynthesis in Arabidopsis thaliana. Overexpression of each of the three genes in the absence of N/NO3 − strongly suppresses the key regulators of anthocyanin synthesis PAP1 and PAP2, genes in the anthocyanin-specific part of flavonoid synthesis, as well as cyanidin- but not quercetin- or kaempferol-glycoside production. Conversely, lbd37, lbd38, or lbd39 mutants accumulate anthocyanins when grown in N/NO3 −-sufficient conditions and show constitutive expression of anthocyanin biosynthetic genes. The LBD genes also repress many other known N-responsive genes, including key genes required for NO3 − uptake and assimilation, resulting in altered NO3 − content, nitrate reductase activity/activation, protein, amino acid, and starch levels, and N-related growth phenotypes. The results identify LBD37 and its two close homologs as novel repressors of anthocyanin biosynthesis and N availability signals in general. They also show that, besides being developmental regulators, LBD genes fulfill roles in metabolic regulation.
An exploratory analysis of librarians' blogs: their development, nature and changes
Authors: Aharony Noa 
Published: November 2009

PurposeThe main purpose of this paper is to compare and examine two points in time of the LIS blogsphere: first period of publication of the blog (first two months for each blog) and a second period (July/August 2008). The research will describe and analyse librarians' blogsphere, focusing on its nature, development, and prevailing tendencies.Design/methodology/approachThis paper presents a statistical descriptive analysis and a thorough content analysis of 30 LIS blogs in two periods of time. The first phase in the investigation is the location of the LIS blogs that meet the research criteria; the second phase is the examination of data related to the posts. The final phase consists of the content analysis of the main ideas of the posts and the development of a subject scheme that represents the analysis.FindingsA thorough examination of blogs' content reveals that there is a current tendency to write essay‐type posts with hypertext links; there are fewer posts and postings days, as well as fewer readers' comments, but a larger number of links and tags which are assigned to the posts. Furthermore, three out of the five main content categories are equivalent in both periods and it seems that the same issues still occupy librarians' minds and thoughts.Originality/valueThe research findings are relevant for librarians and information scientists as they cause them to better understand and delve into the phenomenon of LIS blogsphere.
Explaining the unintended consequences of public sector reform
Authors: Ghobadian Abby , Viney Howard , Redwood John 
Published: November 2009

PurposeThe process of public sector reform in the United Kingdom continues to provoke debate. Even among advocates of the reform process there is a concern that improvements in public service provision have not been as marked as originally intended, and that the process has produced a variety of unintended consequences. The purpose of this paper is to explore possible explanations for these unintended consequences, and discuss possible practical solutions for policy makers and service commissioners.Design/methodology/approachIn this conceptual paper focus is in particular upon attempting to explain managerial behaviour from insights offered by two well‐established managerial theories – stakeholder theory and resource dependency theory. Insights from these theories are used to explain the possible causes of the unintended consequences of the reform process. The discussion is illustrated and set in context by reference to a continuum of service delivery modes from monopoly provision through to full competition.FindingsTheory suggests that managers inevitably prioritise the interests of what they identify as their key stakeholders, and particularly those providing critical resources. In the case of public services this means that the interests of government, as the commissioner and funder of services, are prioritised rather than the end‐users of services. Examples of how this distorts the objectives of government are highlighted. It is argued that understanding this aspect of managerial decision‐making and stakeholder prioritising opens up the potential to resolve the problem.Originality/valueThis is the first paper to address the question of managerial behaviour from these theoretical perspectives in the area of the public sector reform process.
Blogging toward information literacy: engaging students and facilitating peer learning
Authors: Chan Christopher , Cmor Dianne 
Published: November 2009

PurposeThe purpose of this paper is to describe how a course‐integrated blog is used to facilitate the learning of information literacy skills. It also reports on how the effectiveness of the blog is evaluated.Design/methodology/approachThe blog is made the centerpiece of library support offered to a first‐year politics course. With the support of the faculty member involved, students are required to post answers to weekly library research skills questions posted to the blog. The quality of student responses is examined using a simple assessment rubric. Also, a survey is administered to students to determine perceived usefulness.FindingsThe evaluation of blog posts shows that the quality of answers is generally very good. Students put effort into their responses and most give accurate and thorough answers. The results of the survey indicate that most students feel the blog is useful to their learning, both in terms of general information skills, and in terms of helping research the term paper for the course.Research limitations/implicationsThese results reflect just one course at a single university, therefore it is not possible to use the findings to make generalizations. The study could serve as a starting point for further inquiry into the evaluation of blogs as a support tool.Originality/valueWhile others have reported on using blogs in a similar manner, this study also attempts a thorough evaluation of the efficacy of the blog in helping students learn. Given the positive results of this evaluation, librarians could consider using blogs and other Web 2.0 tools to engage students in their own learning.
“More than words”: screencasting as a reference tool
Authors: Carr Allison , Ly Pearl 
Published: November 2009

PurposeThe purpose of this paper is to show how images and videos of search strategies can enhance student experiences in reference interactions by providing a visual and/or auditory explanation, rather than written step‐by‐step instructions. This paper explores how online screencasting tools, such as Jing, can be used to quickly create and share on‐the‐fly videos and images.Design/methodology/approachA literature review briefly discusses uses of screencasting in higher education and the implications for Millennial students, followed by a discussion of how librarians at California State University, San Marcos are creating screencasting videos and images to enhance chat/instant messaging, e‐mail, and in‐person reference interactions.FindingsBased on chat transcripts and anecdotal evidence, students find librarians' use of screencasting helpful in illustrating complex search strategies to find information resources.Research limitations/implicationsFurther research is needed to determine if screencasting is an effective learning tool for Millennial students, as well as, other library users in both reference interactions and instructional settings.Practical implicationsOnline screencasting tools are easy‐to‐use, low‐cost, and can be used in any type of library, specifically for reference services. In virtual reference, librarians can quickly create and share instructional videos rather than type detailed instructions for accessing library and information resources.Originality/valueWhile screencasting tools such as Captivate and Camtasia are widely used in library instruction, they are new to reference delivery. Since many reference interactions include instructional components, on‐the‐fly screencasting can be a useful tool to enhance the user's reference and learning experience.
Connecting older adults to quality health information on the internet: a selective annotated bibliography
Authors: Barrett Felicia A. 
Published: November 2009

PurposeThe purpose of this paper is to provide an annotated listing of studies that focus on older adults and, second, to describe methods by which librarians can provide the necessary tools needed to identify quality web sites that provide reliable health information found on the internet. Individuals are taking more interest in their own health care. The internet is becoming an increasingly important and influential source of health information for the public. Unlike some of the traditional approaches to acquiring health information in the past, the internet is accessible 24/7 to anyone who owns a computer and has an internet connection.Design/methodology/approachThe paper presents a review of the literature that examines how older adults search for health information on the internet and what assistance they need is conducted. Several criteria are used to identify the works that are included in this annotated bibliography. In total, 24 studies meet the criteria.FindingsOlder adults are rapidly becoming the fastest growing group of users of the web. Librarians can play a major role in assisting older consumers locate health information on the internet.Originality/valueThis annotated bibliography provides information about connecting the elderly to quality health information found on the web. Many projects and concepts are discussed. The studies included offer constructive assistance on how to provide programs that will help educate users to become more involved in the health care decision‐making process.

Residential regeneration and adaptive reuse: learning from the experiences of Los Angeles
Authors: Bullen Peter A. , Love Peter E.D. 
Published: November 2009

PurposeAdaptive reuse of older commercial buildings, particularly in countries such as the USA, has been regarded by building owners and developers as uneconomic. Retention of older commercial buildings has commonly been regarded as a barrier to progress and a hindrance to the regeneration of older urban areas. This paper aims to examine the program and legislation that is adopted to encourage the adaptive reuse of commercial buildings in the downtown area of Los Angeles (LA) in the USA, as it is considered to be an exemplar example of how a regeneration strategy makes a contribution to sustainability. It seeks to assess the effectiveness of adaptive reuse of redundant buildings as a commercially viable and effective strategy for urban regeneration that meets the criteria of sustainability.Design/methodology/approachA case example is used to examine the underlying factors that have contributed to LA being an exemplar for adaptive re‐use and its contribution to sustainability.FindingsUrban regeneration requires a vision and a continued commitment to sustainability. In the case of LA, there is clearly evidence of a commitment to sustainability through the implementation of an adaptive re‐use program. A key to this strategy's success is the offering of incentives. Such incentives are required to entice investment and involvement in the program. The ability to make commercial buildings attractive to developers as viable reuse projects relied heavily on the use of legislation that reduces code and zoning requirements and offers substantial financial incentives in the form of tax concessions. The advantages of adaptive reuse in terms of sustainability appear to outweigh the advantages of demolition and new development as experienced in LA. Certainly in terms of urban regeneration the adaptive reuse program in the downtown area appears to have been something of a catalyst in prompting investment in major developments.Originality/valueThe sharing of experiences is pivotal to learning. Such situated learning can provide clients, and industry practitioners with insights about how adaptive re‐use can be used to promote sustainable outcomes. The experiences of LA emphasize the need to consider emphasis on not only environmental and economic benefits but also issues of social equity such as low cost housing for lower income groups. Generally, the objectives of reusing old buildings appear to coincide with many of the desired outcomes of sustainability, but further research is needed to assess the viability of adaptive reuse as a strategy for urban regeneration and sustainability.
Estimation algorithm for predicting the performance of private apartment buildings in Hong Kong
Authors: Yau Yung , Chi‐wing Ho Daniel , Chau Kwong‐wing , Lau Wai‐yip 
Published: November 2009

PurposeFor the sake of public health and safety, a territory‐wide evaluation of the quality of buildings in Hong Kong is crucial. However, it is a lengthy process to assess the performance of the whole stock of buildings in the city. To get around this predicament, this paper aims to propose a statistical approach for a fast and reliable building evaluation algorithm using the Building Quality Index (BQI) developed by The University of Hong Kong.Design/methodology/approachUsing the BQI assessment framework, the condition of 133 and 160 private apartment buildings in Yau Tsim Mong and the Eastern District respectively are assessed and rated. The data of the Yau Tsim Mong buildings are used to estimate a regression model associating the relationships between building performance, measured by the BQI, and other exogenous factors. The resulting model is then employed to predict the performance of the surveyed buildings in the Eastern District.FindingsThe regression analyses on the Yau Tsim Mong data indicate that building age, development scale and building management mode are significant determinants of the existing condition of the sampled buildings, echoing the findings of previous studies. BQI scores of buildings in the Eastern District are estimated using the resulting regression model, and there is a highly positive relationship between the predicted BQI and in‐situ BQI scores.Originality/valueThe study is the first in the literature to provide an algorithm for estimating building condition in a densely developed high‐rise urban area.
Thermal behaviour of vented roofs
Authors: D'Orazio M. , Di Perna C. , Stazi F. 
Published: November 2009

PurposeThe purpose of this paper is to present the results of an experimental study aimed at analysing the effect of the roof tile air permeability on the thermal performances of ventilation ducts in the roof. The main reason underlying this study is the fact that the theoretical reference assumed for the manufacture and sizing of ventilation ducts (the accepted theory on roof ventilation) is clearly limited when applied to ducts which are not perfectly airtight (Hens) and results in an oversizing of the ventilation ducts.Design/methodology/approachA section of roof is built, covered with different tiles and environmental and meteorological data collected. The data are analysed statistically.FindingsThe results show that the permeability of the layer of tiles determines heat losses which are in addition to those connected with the stack effect in a perfectly airtight duct with the same features. The results also confirm the correlation which has already been demonstrated between the geometric ratio of the length of the duct divided by its height and the amount of heat dissipated by the roof (Sandberg and Moshfeg).Originality/valueThis study analyses the performance of the roofs only during the summer season. The research is therefore continuing with a long‐term (one year) analysis of the roofs characterised by a high level of roof tile permeability so as to understand the consequences that the presence of a ventilation duct in systems with air permeable roofing may have on the thermal efficiency of the roof.
Why supervisors make idiosyncratic deals: antecedents and outcomes of i‐deals from a managerial perspective
Authors: Hornung Severin , Rousseau Denise M. , Glaser Jürgen 
Published: November 2009

PurposeIdiosyncratic deals are personalized employment conditions individual workers have negotiated. This study aims to investigate influences on supervisors' authorization of i‐deals and their evaluation of these arrangements.Design/methodology/approachStructural modeling was used to analyze survey data fromn=263 supervisors managing telecommuting employees in the German public administration.FindingsSupervisors differentiated among i‐deals regarding development, flexibility, and workload reduction. Their authorization of developmental i‐deals was influenced by employee initiative. Supervisors viewed these i‐deals to have positive implications for employee motivation and performance. Flexibility i‐deals were influenced by structural conditions such as the type of work the employee performed. Supervisors viewed these i‐deals to enhance work‐life benefits. Supervisors tended to grant workload reduction i‐deals in the context of unfulfilled organizational obligations towards employees.Research limitations/implicationsRelying on single‐source cross‐sectional data, our results provide a managerial perspective on i‐deals. Conclusions regarding implications for employees are tentative. Recommendations for future study designs are discussed.Practical implicationsManagers need to better recognize that i‐deals take different forms, and these forms are associated with different outcomes. I‐deals provide a way to experiment with innovative human resource practices.Originality/valueThis is the first study to examine i‐deals from a supervisor perspective. It is the first to identify differential circumstances and consequences managers associate with authorizing three distinct forms of i‐deals.
Different views of trust and relational leadership: supervisor and subordinate perspectives
Authors: Werbel James D. , Lopes Henriques Paulo 
Published: November 2009

PurposeThe purpose of the study is to investigate how the conditions of trust differ between supervisors and subordinates. By understanding these differences, it may be possible to improve the quality of a leader‐member exchange (LMX).Design/methodology/approachThis is a quantitative study using supervisor and subordinate dyads from Portugal.FindingsSupervisors reported that receptivity, availability, and discreteness were perceived to be more important in building a quality vertical dyad linkage as represented by LMX. Subordinates reported that availability, competence, discreteness, integrity, and openness were more important for building a quality vertical dyad linkage as represented by LMX.Research limitations/implicationsStatus differences between supervisors and subordinates appear to influence conditions of trust. Supervisors are more concerned about conditions of trust that deal with supervisory delegation. Subordinates are more concerned about the conditions of trust based on interactional justice.Originality/valueThis research implies that trust is different between supervisors and subordinates. The research is important in building supervisor and subordinate relationships as both need to act in manners that engenders trust from the other side. The difference in conditions of trust may create conflicting expectations about how to effectively build trust.
Emotional labor: links to work attitudes and emotional exhaustion
Authors: Seery Brenda L. , Corrigall Elizabeth A. 
Published: November 2009

PurposeThe purpose of this study is to explore the links from self‐focused emotional labor (surface acting) and other‐focused emotional labor (emotional enhancement) to job satisfaction, affective commitment, emotional exhaustion, and intentions to quit.Design/methodology/approachThe study employed a cross‐sectional survey of 363 nurses' aides and childcare workers.FindingsSurface acting, a type of self‐focused emotional labor, was related to negative work outcomes (lower job satisfaction and affective commitment as well as higher turnover intentions and emotional exhaustion). Emotional enhancement, a form of other‐focused emotional labor, was related to positive outcomes (lower turnover intentions and emotional exhaustion) when performed for clients' family members, but not for clients.Research limitations/implicationsThe cross sectional design of this study limits the ability to map the temporal ordering of these relationships, and thus to determine if emotional enhancement is a job resource or response to positive work experiences. In addition, two helping occupations – nurses' aides and child care workers – were sampled, and thus, the findings may not generalize to other types of occupations.Originality/valueThis study adds to the research about job‐related emotional labor because other‐focused emotional labor largely has been neglected in previous research. In addition, it is the first to differentiate workers' emotional labor with different groups of clients (patients/children; family members).
