ArabidopsisRETINOBLASTOMA-RELATED Is Required for Stem Cell Maintenance, Cell Differentiation, and Lateral Organ Production
Authors: Borghi Lorenzo , Gutzat Ruben , Fütterer Johannes , Laizet Yec'han , Hennig Lars , Gruissem Wilhelm 
Published: June 2010

AbstractSeveral genes involved in the regulation of postembryonic organ initiation and growth have been identified. However, it remains largely unclear how developmental cues connect to the cell cycle. RETINOBLASTOMA RELATED (RBR) is a plant homolog of the tumor suppressor Retinoblastoma (pRb), which is a key regulator of the cell cycle. Using inducible RNA interference (RNAi) against Arabidopsis thaliana RBR (RBRi), we reduced RBR expression levels at different stages of plant development. Conditional reduction or loss of RBR function disrupted cell division patterns, promoted context-dependent cell proliferation, and negatively influenced establishment of cell differentiation. Several lineages of toti- and pluripotent cells, including shoot apical meristem stem cells, meristemoid mother cells, and procambial cells, failed to produce appropriately differentiated cells. Meristem activity was altered, leading to a disruption of the CLAVATA-WUSCHEL feedback loop and inhibition of lateral organ formation. Release of RBR from RNAi downregulation restored meristem activity. Gene profiling analyses soon after RBRi induction revealed that a change in RBR homeostasis is perceived as a stress, even before genes regulated by RBR-E2F become deregulated. The results establish RBR as a key cell cycle regulator required for coordination of cell division, differentiation, and cell homeostasis.
The Conserved Splicing Factor SUA Controls Alternative Splicing of the Developmental Regulator ABI3 in Arabidopsis

Abstract
ABSCISIC ACID INSENSITIVE3 (ABI3) is a major regulator of seed maturation in Arabidopsis thaliana. We detected two ABI3 transcripts, ABI3-α and ABI3-β, which encode full-length and truncated proteins, respectively. Alternative splicing of ABI3 is developmentally regulated, and the ABI3-β transcript accumulates at the end of seed maturation. The two ABI3 transcripts differ by the presence of a cryptic intron in ABI3-α, which is spliced out in ABI3-β. The suppressor of abi3-5 (sua) mutant consistently restores wild-type seed features in the frameshift mutant abi3-5 but does not suppress other abi3 mutant alleles. SUA is a conserved splicing factor, homologous to the human protein RBM5, and reduces splicing of the cryptic ABI3 intron, leading to a decrease in ABI3-β transcript. In the abi3-5 mutant, ABI3-β codes for a functional ABI3 protein due to frameshift restoration.
Seniority and gender differences in 360‐degree assessments of influencing, leadership and team behaviours. Part 2: Gender differences, conclusions and implications
Authors: Manning Tony , Robertson Bob 
Published: June 2010

PurposeThe purpose of this two‐part paper is to present and discuss research into gender and seniority differences in 360‐degree assessments of influencing, leadership and team behaviours.Design/methodology/approachThe article builds on a previous article on influencing behaviour and 360‐degree assessments that found a statistically significant positive relationship between these two sets of variables. However, the strength of this relationship was found to vary, depending on the seniority and gender of individuals. This article extends the previous one in two ways. Firstly, it examines four hypotheses to explain the earlier findings. Secondly, it introduces data on two other types of behaviour – leadership and team behaviour – in relation to 360‐degree performance assessments.FindingsThe authors found support for the first hypothesis. The 360‐degree assessments are affected by seniority. Influencing behaviour is more closely linked to 360‐degree assessments of middle managers who tend to have less legitimate power. The authors found little support for the second hypothesis. The 360‐degree assessments were strongly related to leadership and team behaviours in senior managers, as well as middle managers. The authors found clear evidence to support the third hypothesis that male and female managers were judged by different gender stereotypes. The authors also found support for the fourth hypothesis that male and female managers tended to do different jobs.Originality/valueThe originality and value of this paper lies in its examination of the relationship between three different types of behaviour (i.e. influencing, leadership and team working) and 360‐degree assessments of performance, including seniority and gender differences. It combines theory and research as a basis for practice. It draws on relevant theory on influencing, team working and leadership, presents empirical evidence, examines possible interpretations, draws practical conclusions and discusses their implications. The findings have implications for the use of 360‐degree assessments, challenge universal prescriptions about leadership and management, provide guidelines about the development needs of managers as they move from middle to senior management levels, and highlight particular problems for female managers making the transition.

Authors: Adungbe Bamikole Musibau , Julius Ikhatua Uamai 
Published: June 2010

PurposeThe realization of the importance of browse in meeting the nutritional needs of ruminants in the dry season in the tropics has put a serious pressure on the already known browse plants. The purpose of this paper is to evaluate the nutritive value of Ficus thonningii (FT), which is a less known fodder tree.Design/methodology/approachA total of 25 West African dwarf goats (age range = 7‐9 months, live weight range = 5.0‐7.5 kg) were used for the study, and lasted for 98 days. FT was fed with Panicum maximum (PM) grass in different proportions of 0:100 (only grass), 25:75, 50:50, 75:25 and 100:0 (only Ficus) to five groups of goats. A completely randomized design was used to collect data on feed intake, digestibility, weight gain and nitrogen utilization.FindingsResults showed that FT is higher in crude protein (CP) (20.51 per cent) and lower in neutral detergent fibre (NDF) (55.79 per cent) than PM (CP = 8.25 per cent, NDF = 76.16 per cent). Dry matter (DM), organic matter (OM), CP intakes (g/d/kg w0.75) improved significantly with more FT in the diet and were best in 75 per cent FT (values = 79.84, 76.72 and 14.78, respectively) and lowest in solely PM (corresponding values = 21.06, 18.21 and 1.59). Weight gain (g/d) patterned nutrient intake and were best in 50 and 75 per cent FT (mean = 14.78) and least in solely PM (5.36). Digestibility values were generally good, but highest in 50 per cent FT, similar in 25, 75 and 100 per cent FT and least in solely PM. Nitrogen balance (g/d) and retention (per cent) were highest and similar in both 50 and 75 per cent FT (mean = 4.8 and 48.79) and lowest in solely grass (0.24 and 14.25).Practical implicationsFT displays no practical limitations to its utilization in ruminant feeding and could be used solely or in mixture with grass.Original/valueBeing well consumed and utilized even as sole forage, FT will be a good insurance in alleviating feed scarcity problem for ruminant animals in the dry season.
Assessing the home food environment nutrient supply using mobile barcode (Universal Product Code) scanning technology
Authors: Byrd‐Bredbenner Carol , Bredbenner Carl A. 
Published: June 2010

PurposeMobile Universal Product Code (UPC), or barcode, scanning technology provides an efficient, accurate and comprehensive method for conducting home food inventories intended to describe the household's nutrient supply. However, heretofore this technology has had limited use in research because of equipment and software complexities. Thus, the purpose of this paper is to describe a data collection system that overcame these complexities.Design/methodology/approachA data collection system was developed that utilized off‐the‐shelf barcode scanners and laptop computers running commercial diet analysis software modified to use two large databases linking UPCs with nutrient data in addition to usual data sources (e.g. USDA Standard Reference). This system was designed for use at the data collection site to ensure 100 percent verification that scanned UPCs on food packages matched database foods and make corrections as needed. This system also permitted researchers to capture the presence of foods lacking standard UPCs (e.g. fresh produce) using a keyword search. To ensure that all data were collected uniformly and new foods not in the original database were added to the database in the same fashion, a protocol flowchart consisting of a series of branching “yes/no” questions was developed and applied to each food of interest in the household.FindingsThe system was used to conduct household food inventories of 160 families with widely varying socioeconomic strata and races/ethnicities. Households had between 13 and 389 foods on hand, the vast majority of which were identified by standard UPCs. The average inventory took approximately two hours. Study participants expressed interest in the data collection method and were very cooperative.Practical implicationsHome food inventories conducted by researchers are objective and help minimize reporting errors and social desirability bias; however, the cost (e.g. researcher time, equipment, software, and database licensing) of conducting home food inventories, even using mobile UPC scanning technology, is important to consider. To improve access to databases linking UPCs and nutrients, collaborative links between researchers and industry are needed.Originality/valueThis paper is among the first to demonstrate the feasibility of using mobile barcode scanning technology to conduct home food inventories on a large‐scale basis and solve the technical problems associated with this data collection methodology.

Authors: Liu Shao‐Quan , Tsao Marlene 
Published: June 2010

PurposeThere is a need to improve stability of lactic acid bacteria (LAB) and probiotics in fermented milks especially at elevated temperatures. The purpose of this paper is to evaluate the impact of yeast Williopsis saturnus var. saturnus on stability of LAB and probiotic Lactobacillus rhamnosus in fermented milks.Design/methodology/approachFermented milks were made from reconstituted whole milk with different milk solids contents. The milk was fermented with L. rhamnosus DR20 with and without yoghurt cultures. The treatment had yeast added, whereas the control did not. Fermented milks were incubated at different temperatures and samples were taken regularly for microbial count determination.FindingsThe effect of the yeast on stability of L. bulgaricus and L. rhamnosus varied with temperatures: no effect at 4 and 40 ○C, increasing effects from 10 to 30 ○C with enhanced lactobacilli survival by 102 to 107‐fold. The yeast enhanced L. bulgaricus and L. rhamnosus stability by approximately 106 to 107‐fold in fermented milks with 5 per cent w/v and 20 per cent w/v milk solids at 30 ○C.Research limitations/implicationsUse of live yeast has limitations. The yeast must not ferment lactose and galactose, and fermentable sugars cannot be used as sweeteners to avoid yeast growth. Further understanding of the interaction between yeast and LAB may eliminate the need to add viable yeast.Originality/valueUse of yeast to enhance stability of LAB and probiotics is a novel concept. Addition of selected yeast could be an effective means of enhancing stability of LAB and probiotics in fermented milks to extend shelf‐life and to retain nutritional value.

Published: June 2010

PurposeThe purpose of this paper is to compare food utilization of quality protein maize (QPM) to other maize varieties.Design/methodology/approachPap (ogi) – a maize starch porridge was prepared from QPM, tropical Zea mays early (TZE) and local maize (LM) using the traditional method. Physicochemical, microbiological and sensory analyses were carried out on the pap samples as indices of quality following standard methods.FindingsThe sensory evaluation preference rating for pap (ogi) prepared from QPM, TZE and LM varieties showed no significant difference (p < 0.05) in flavour, taste, colour and overall acceptability. Significant difference was however observed in the pH of the three products.Practical implicationsThe findings suggested that QPM have the potential to replace other maize varieties as a staple diet and cheap source of quality protein.Originality/valueThis paper contributes knowledge to the fight against malnutrition and hunger, especially in the sub‐Saharan Africa.

Authors: Goyal Rajni , Grewal Rajbala 
Published: June 2010

PurposeAn elevated level of cholesterol in blood is quite common nowadays. People are becoming more health conscious. The purpose of this paper is to study the hypocholesterolemic effect of teent, as it is a rich source of dietary fiber.Design/methodology/approachTeent was processed and analyzed for proximate coposition and dietary fiber constituents. Fifteen obese volunteer subjects having high blood lipid profile were selected for the experiment. Fasting blood samples were analyzed for total, low‐density lipoprotein (LDL) and high‐density lipoprotein (HDL) cholesterol initially before start of feeding experiment and at the end of experiment. Teent was processed and various products using teent or teent powder were standardized. Best acceptable products, namely, chutney and biscuits were supplemented in the diets of the subjects for three months.FindingsThe nutritional evaluation of teent indicates that it contains a good amount of protein and fiber. A significant decrease in the total cholesterol (13 percent) and LDL cholesterol (16 percent) was noticed at the end of the experiment. However, no significant change in HDL cholesterol was witnessed.Originality/valueIn the present scenario due to urbanization more and more people are facing problem of obesity and related heart diseases. At the same time they also want to avoid consuming medicines due to their side effects so results indicate that teent supplementation may have an important role in nutritional management of hypercholesterolemia.

Published: June 2010

PurposeThe purpose of this paper is to discuss Hong Kong Baptist University Library's MyLibrary Calendar Project to streamline library‐patron communication and to strengthen the Library's publicity for its services, facilities and outreach activities.Design/methodology/approachThe paper examines the application of an in‐house developed iCalendar Data Conversion Program and Innovative Millennium Patron API Form in this Project. The iCalendar Data Conversion Program extracts and converts data from library announcements, interlibrary loan and circulation records, library e‐mails and notices, and records of library facilities reservation to iCalendar format for dissemination to patrons. The Innovative Millennium Patron API Form, on the other hand, authenticates patrons' subscription to the services.FindingsThe project employs Web 2.0 technologies and social networking software such as iCalendar format, calendar applications, API and Google Calendar SMS notification option to publish, syndicate, and aggregate dynamic web content in a Library 2.0 model. It enables patrons to use their own personal calendar computer applications that support the open and standard iCalendar format as a one‐stop‐shop platform to automatically collect and manage library calendar events, library e‐mails and notices, and their own records of circulation, interlibrary loan and room reservation in an efficient and centralized channel.Originality/valueMyLibrary Calendar is a unique Web 2.0 and Library 2.0 compliant tool. It enables patrons to collect and manage library events and their own library records systematically in their own calendar applications. This tool also facilitates the Library to proactively publicize its services and facilities effectively and to bring about a shift in power and new library‐patron relationship smoothly.
Differences among university students and faculties in social networking site perception and use
Authors: Park Ji‐Hong 
Published: June 2010

PurposeSocial networking sites (SNSs) are gaining popularity in various areas. Library and information services also are attempting to utilize them for increasing the library user traffic. Considering the lack of SNS studies in academic library services and various SNS usage patterns according to user type, it is necessary to compare the usage patterns across different user groups. This paper thus aims to explore the usages of a SNS by different university users.Design/methodology/approachData were collected through semi‐structured and open‐ended interviews conducted with undergraduates, graduates, and faculty members at Yonsei University in Seoul, South Korea. Data were analyzed according to the three groups (undergraduates, graduates, and faculty members) and within each group SNS user perception and use were examined across the three different user activity groups (active users, semi‐active users, and non‐active users).FindingsThe analyses indicated that the three groups of users demonstrated distinct patterns of SNS use. Although undergraduates used the profile service more than the community service, graduates used the community more than the profile service. Most faculty members were not active users. Six factors that affected these different usage patterns were identified: desire for expression, peer influences, familiarity with information technologies, sensitivity to privacy, nature of using the internet, and perception of the SNS.Practical implicationsA differentiated approach is necessary for SNS‐based academic library services.Originality/valueThe paper makes useful and initial suggestions for implementing SNS‐based library and information service in academic settings.

Authors: Chandrakar Rajesh , Arora Jagdish 
Published: June 2010

PurposeThe purpose of this article is to provide an Indian perspective on copy cataloguing and its current position in libraries.Design/methodology/approachThe study is based on the experiences of visiting various colleges and universities across the country. The paper explains copy cataloguing and its sources available to the Indian libraries for retrospective conversion.FindingsCopy cataloguing in India is not widespread. The supply of a “ready cataloguing” in MARC format by Indian publishers and supply agents is also not widely available.Practical implicationsCopy cataloguing features have been implemented into the SOUL software and the IndCat, an online union catalogue of Indian universities for the Indian libraries.Originality/valueIt is observed that copy cataloguing features have never been explained in one place for Indian libraries. The information provided in the paper will help the community at large.

Authors: Alipour‐Hafezi Mehdi , Horri Abbas , Shiri Ali , Ghaebi Amir 
Published: June 2010

PurposeThe purpose of this paper is to provide an overview of the existing interoperability models in digital libraries and to introduce related projects in each model.Design/methodology/approachThe study starts from searching various databases with a combination of important keywords in the field, such as interoperability, digital library, meta‐searching and cross‐searching. The study follows up with describing related digital library projects in the field of technical interoperability. The projects are described under three main categories, Federated, Harvesting and Gathering.FindingsThe study shows that most of the studied projects are located in the USA and also most of the digital library projects use OAI protocol and the harvesting model in order to be technically interoperable. Also, the results of the study showed that the projects mostly paid attention to metadata interoperability and only a few mentioned full‐text interoperability issues.Originality/valueThe paper makes an original contribution of exploring an area (interoperability models in digital libraries), that is at the forefront of discussion in libraries worldwide.
Training needs of purchasing and supply management personnel in Hong Kong
Authors: Lau Antonio K.W. 
Published: June 2010

PurposeThe importance of purchasing and supply management (PSM) for business performance has received considerable attention in recent years. However, research on PSM training and education is inadequate. This paper aims to present initial findings from PSM practitioners about current PSM training and education needs in Hong Kong.Design/methodology/approachAn industrial survey of PSM participants was conducted. Of the 405 PSM practitioners contacted, 53 responded to the survey, for a response rate of 13.1 percent.FindingsThe study identifies current trends, skills and knowledge areas for PSM professionals. The results show that the trends of PSM focus on purchasing cost reduction, the skills focus on negotiation and communication, and the knowledge on supply analysis and relationship management. The study also finds that companies tend to adopt on‐the‐job training for PSM staff but lack a systematic PSM training approach.Research limitations/implicationsThe study suggests that human resource development for PSM staff must focus not only on tactical techniques, but also on managerial knowledge and skills. However, the sampled companies are weak at providing PSM training and measuring its results. As this study is limited by the small sample size and the nature of the surveyed region, more empirical research will be required to study the effectiveness of PSM training on business performance.Practical implicationsThis study shows that companies are weak at staff training in the studied region. Most of the companies surveyed do not have formal training programs and training effectiveness measurements. Knowledge of this is essential for other similar organizations wanting to improve their PSM personnel.Originality/valueThis paper identifies current trends, skills and knowledge required for PSM in Hong Kong, which have not previously been reported in literature.
