Published: January 2010

Lily is an economically important ornamental crop in Korea. In August 2008, severe leaf spot symptoms were observed on an oriental Lily ‘Action’ in a plant nursery in Daegu, Korea. Disease incidence was 20 to 30%. Initial symptoms were olive green-to-brown lesions on the leaf that developed into tan, elliptical, necrotic lesions. On severely infected leaves, lesions coalesced and killed the entire leaf blade. Infected leaves were surface disinfested with 70% ethanol for 30 s and 2% chlorox for 15 min before plating 1 cm2 sections onto potato dextrose agar. Hyphae appeared 5 days after inoculation and pure culture. Conidia were hyaline, transversely septate with one to three septa; most had two. Conidia were obpyriform and measured 29 to 46 μm long and 7 to 17 μm wide. Mycelia morphology and conidia production were consistent with that described previously for Pyricularia grisea (1). Koch's postulates were fulfilled by spraying five, healthy, vegetative-stage plants with 2 × 105 conidia per ml of sterile distilled water plus 0.05% Tween 20. As a control, five similar plants were sprayed with sterile water plus 0.05% Tween 20 only. Plants were placed inside plastic bags to maintain high relative humidity and incubated in a growth chamber at 25°C under fluorescent light for 14 h and at 20°C in darkness for 10 h. After 3 days, the plastic bags were removed and plants were maintained under the same conditions. Initial symptoms were observed 7 days after inoculation. Ten days after inoculation, disease symptoms on inoculated plants were similar to those previously described in the nursery. Control plants did not show any symptoms. Fungi isolated from these lesions had the same morphological characteristics as the ones isolated previously from plants in the nursery. To our knowledge, this is the first report of gray leaf spot on lily caused by P. grisea in Korea. References: (1) M. B. Ellis. Dematiaceous Hyphomycetes. CMI, Kew, Surrey, UK, 1971.

Evolving mobile communication practices of Irish teenagers
Authors: Cawley Anthony , Hynes Deirdre 
Published: January 2010

PurposeThe purpose of this paper is to examine the social adoption of the mobile phone by Irish teenagers in city, town and rural settings. It aims to investigate two key areas that have influenced the teenagers' social adoption of the mobile phone: first, the influence of locational and socio‐economic factors on mobile phone usage; second, how the teenagers' adoption of recently emergent Web 2.0 applications (social‐networking web sites and instant messaging services) tends to bring about a re‐positioning of the mobile phone's role as a communications channel.Design/methodology/approachThe paper draws on a social shaping and domestication of media technologies approach, using original empirical data from a survey of teenage respondents and six focus groups.FindingsThe findings suggest that the teenagers' relationship to the mobile phone is evolving as newer communications applications emerge. In particular, the technical competencies and media literacies necessary for multi‐model communication are evolving fastest where locational and socio‐economic conditions are most favourable.Originality/valueAlthough access to the mobile phone cuts across the strata of society, people's capacity to benefit from it – and from other forms of multi‐modal communication – is not evenly distributed. The paper argues that, despite universal ownership of the technological device among the sample of teenagers, the mobile phone is caught up in wider digital and socio‐economic divides.

Authors: Shahnavaz Zohreh , Jeffrey Basirun Wan , Zain Sharifuddin Mohd. 
Published: January 2010

PurposeThe purpose of this paper is to study the inhibitory activity of benzene‐1,2,4,5‐tetracarboxylic dianhydride (PMDH) on aluminium corrosion in hydrochloric acid 1 M HCl.Design/methodology/approachThe inhibitive effect of PMDH towards the corrosion of aluminium in 1 M HCl solution is studied by means of electrochemical impedance spectroscopy, polarization curves (LSV) and scanning electron microscopic techniques. The effect of inhibitor concentration and temperature against inhibitor action is investigated.FindingsIn the presence of inhibitor (PMDH), the corrosion resistance of aluminium is improved and the corrosion rate and corrosion current are reduced, therefore the inhibition efficiency and polarization resistance are increased. With increasing temperature and decreasing inhibitor concentrations, the rate of aluminium corrosion increased. The surfactant acts as mixed type inhibitor and obeys a Langmuir isotherm.Originality/valueThe results shown in this paper are an insight to the understanding of the corrosion resistance and electrochemical behaviour of aluminium for future industrial applications and development.
Turning weakness into strength: strategies for future LIS
Authors: Nolin Jan , Åström Fredrik 
Published: January 2010

PurposeLIS has been described as a fragmented field in crisis, with an increased competition from other fields; and lacking in development of theories. The purpose of this paper is to articulate a strategy in which the perceived weakness can be seen as a source of strength.Design/methodology/approachThe text builds mostly on reflections on meta‐theoretical and science‐organisation literature. Ten distinct problems for the research field are identified and discussed in order to provide a viable strategy for the future.FindingsWhile it is common to suggest a convergent movement toward the idealised characteristics of the strong research discipline as a recipe against fragmentation, a strong convergent movement is suggested that feeds off the fragmented character of the field. What is commonly perceived as a weakness, the multidimensional character of the field, can be translated into a strategic resource.Originality/valueThe paper provides a fresh perspective on the strategic situation of LIS.

Authors: Timmers Caroline F. , Glas Cees A.W. 
Published: January 2010

PurposeThe main purpose of this paper is to describe the development of an instrument designed to measure information‐seeking behaviour of undergraduate students during study assignments.Design/methodology/approachLiterature research, internal consistency and reliability computed with Cronbach's Alpha (α), Factor Analyses with Varimax rotation, and item response theory form the approach to examining the subject.FindingsFour scales were found within a 46‐item survey on information‐seeking behaviour: a ten‐item scale for applying search strategies (α=0.68), a 14‐item scale for evaluating information (α=0.74), a six‐item scale for referring to information (α=0.81) and a 12‐item scale for regulation activities when seeking information (α=0.75).Originality/valueThe four scales for information‐seeking behaviour can be used to monitor and evaluate this behaviour of students in higher education.
Robot Show 2009: music to the ears, literally
Authors: Bloss Richard 
Published: January 2010

PurposeThe purpose of this paper is to review the biannual Robot Show in Chicago with emphasis on innovative robot applications on display.Design/methodology/approachThe approach takes the form of in‐depth interviews with exhibitors of robots as well as system integrators who apply robots to specific categories of applications.FindingsRobots are rapidly moving from the industrial environment into all types of service applications. They are also becoming more autonomous, more mobile, finding their own way and delivering critical loads in office, hospital, and laboratory settings and even providing security functions.Practical implicationsUsers who investigated robot solutions in the past and found that they did not meet applications requirements may find it is time to revisit robotics. Robot builders and system integrators are providing more suitable solutions that can better address application needs in a more cost‐effective manner than ever before.Originality/valueRobots for non‐industrial applications are receiving lots of attention. Many first time exhibitors at the recent biannual Robot Show featured units for personal service, healthcare, and other non‐industrial applications.

Authors: Bogue Robert 
Published: January 2010

PurposeThe purpose of this paper is to provide a review of recent developments in miniaturised flying robots.Design/methodology/approachFollowing a brief consideration of micro‐ and nano‐aerial vehicles, the paper discusses recent US and European research into the development of miniaturised flying robots.FindingsThis paper shows that research into miniaturised flying robots is gaining pace and much is being funded by the US military. Two major strands of research are devices which mimic the flight dynamics of insects and living insect‐microtechnology hybrids (cyborgs). The technologies remain at an early stage of development but covert surveillance and intelligence gathering are key future applications.Originality/valueThe paper provides a technical review of the latest developments in miniaturised flying robots.
A practical approach for minimum‐time trajectory planning for industrial robots
Authors: Kim Joonyoung , Kim Sung‐Rak , Kim Soo‐Jong , Kim Dong‐Hyeok 
Published: January 2010

PurposeThe purpose of this paper is to maximize the speed of industrial robots by obtaining the minimum‐time trajectories that satisfy various constraints commonly given in the application of industrial robots.Design/methodology/approachThe method utilizes the dynamic model of the robot manipulators to find the maximum kinematic constraints that are used with conventional trajectory patterns, such as trapezoidal velocity profiles and cubic polynomial functions.FindingsThe experimental results demonstrate that the proposed method can decrease the motion times substantially compared with the conventional kinematic method.Practical implicationsAlthough the method used a dynamic model, the computational burden is minimized by calculating dynamics only at certain points, enabling implementation of the method online. The proposed method is tested on more than 40 different types of robots made by Hyundai Heavy Industries Co. Ltd (HHI). The method is successfully implemented in Hi5, a new generation of HHI robot controller.Originality/valueThe paper shows that the method is computationally very simple compared with other minimum‐time trajectory‐planning methods, thus making it suitable for online implementation.
A novel control algorithm for weld pool control
Authors: Lü Fenglin , Chen Huabin , Fan Chongjian , Chen Shanben 
Published: January 2010

PurposeQuality control of arc welding process is the key component in robotic welding system. The purpose of this paper is to address vision‐sensing technology and model‐free adaptive control (MFC) of weld pool size during automatic arc welding system.Design/methodology/approachThe shape and size parameters for the weld pool are used to describe the weld pool geometry, which is specified by the backside weld width. The welding current and wire‐feeding speed are selected as the control variable, and the backside width of weld pool is selected as the controlled variable. To achieve the goal of full penetration and fine weld seam formation, a multiple input single output (MISO) MFC is designed for control of the backside pool width.FindingsThe research findings show that it is feasible to develop such a MISO MFC of weld pool size, which is independent on mathematic model of weld pool dynamics. And the control algorithm is simple to use and has a minimal computational burden.Research limitations/implicationsThis is a work in progress. The controlled process results are mainly influenced by the period of competing control algorithm and image processing, which could be improved by the hardware and enhancing computation speed. The closed‐loop control is a two inputs‐one output system. Thus, the means by which the multiple input multiple output (MIMO) control method is applied to weld pool dynamics is work for the future.Practical implicationsThe control system is applicable to automatic gas tungsten arc welding (GTAW).Originality/valueThe MISO MFC has been set up for automatic GTAW to overcome the nonlinear and uncertainty of GTAW process, in which two welding parameters can be adjusted simultaneously. In addition, this controller is independent on welding pool dynamic model.
Managing collection development and organization in globalizing Indian university libraries
Authors: Mannan Khan Abdul 
Published: January 2010

PurposeThe main purpose of the study is to identify the current status of collection development organizational patterns and to make a comparative analysis of collection development organizational patterns of the four central university libraries of Uttar Pradesh (UP) i.e. Aligarh Muslim University (AMU), Banaras Hindu University (BHU), Allahabad University (ALU) and Baba Bhim Rao Ambedkar University (BBRAU).Design/methodology/approachA well structured questionnaire was administered to the librarians and acquisitions librarians of the four central university libraries under study.FindingsIt has been found that there is a conspicuous difference between the two categories and that the newly centralized universities are lagging far behind the old centralized universities in collection development organizational patterns.Research limitations/implicationsThe present study consists only of collection development organizational patterns in central university libraries of UP. The scope of the study can be extended to some more centrally funded universities.Originality/valueThere are a number of studies on collection development organizational patterns in the world, but this is the first of its kind within Indian central universities.
Resources for selecting popular music recordings
Authors: Tewell Eamon 
Published: January 2010

PurposeThe purpose of this paper is to assist music selectors at academic and public libraries by providing resources useful for selecting popular sound recordings, while emphasizing the ongoing need for monitoring trends and new releases in popular music.Design/methodology/approachThis paper identifies key resources to aid the selection of popular music recordings, beginning with the challenges unique to popular music. The resources are divided into four major sections: online tools, print tools, periodical tools, and staying current.FindingsPopular music is widely collected by libraries, yet selection and acquisition is made difficult by the numerous genres and constant rotation of popular artists and albums. The utilization of a variety of online and print resources is ideal in order to build or maintain a well‐stocked popular music collection.Originality/valueThis paper offers guidance to librarians responsible for sound recordings. No previous discussions of music selection have considered popular music as a whole, while popular music recordings are widely collected by libraries and require a great deal of currency.

Published: January 2010

PurposeThe purpose of this paper is to build a working definition of public administration's management capacity (PA‐MANCAP) aiming at empirically testing the existence and size of an implementation gap in public management reforms in Italy.Design/methodology/approachA confirmatory factor analysis is developed to assess the validity of the proposed operational measure. Data are taken from a survey administered on 204 local governments in Italy.FindingsThe validity of the measure is assessed for all the attributes that conceptualize PA‐MANCAP except for the information and communication technology dimension. Findings from a survey of 102 major Italian municipalities indicate a situation with areas of light and shadow with regard to the implementation of public management reforms in Italy.Originality/valueThe paper presents a valuable insight for both academics and practitioners in order to benchmark the managerial capacity of various local governments and to develop additional quantitative research into the determinants of the implementation gap of public management reforms in Italy and abroad.
An institutional review of planning budgeting and monitoring in the Caribbean
Authors: Bissessar Ann Marie 
Published: January 2010

PurposeThe purpose of this paper is to present an institutional overview of the budgeting systems that are employed during three major periods: pre‐1960s, post‐1960s and 1990s to present New Public Management (NPM budgeting) in five Caribbean countries: Trinidad and Tobago, Barbados, Belize, Guyana and Jamaica.Design/methodology/approachThe paper looks at the budgeting systems that are employed during the period of colonial rule, when the countries attained independence and the budget system that is presently employed. It relies heavily on the financial regulations to explain the procedures that are employed in budgeting during the pre‐independence period.FindingsIt suggests that while the budgeting systems during the pre‐1960s may have been effective, given the scope and functions of government at that period, as countries attained independence the systems would have been found to be inadequate to meet the needs of the country since the scope and size of public sector activities would have increased considerably. The paper then examines the attempt by the various countries, during the 1980s and 1990s, as they attempted to introduce New Financial Management Initiatives as one aspect of the move towards NPM. While a number of these countries attempted to introduce the foundation on which to introduce the initiative, however, it is found that there are a number of challenges in introducing these changes. The paper accordingly examines some of these challenges.Originality/valueThis paper is to date the only attempt to assess budgeting in Caribbean territories.
Managerial innovations in central government: not wrong, but hard to explain
Authors: Arnaboldi Michela , Azzone Giovanni , Palermo Tommaso 
Published: January 2010

PurposeThe purpose of this paper is to explore the adoption of managerial innovations in the public sector, identifying the reasons why their uptake and use may fail.Design/methodology/approachThe problem is investigated empirically through a case study approach. The change processes resulting from the adoption of two managerial innovations within the same Italian Central Government Institution are illustrated in detail.FindingsBoth cases represent a failure in the adoption and use of managerial innovations, attributable to a complex interplay of external and organisational forces. The empirical investigation points out the relevancy of individuals' actions and choices. The real explanation for the failure of both projects in fact seems to be key individuals' inability: first to “make sense” of what the innovation was about and second to communicate this “sense” throughout the organisation.Research limitations/implicationsThe findings are based on data from the Italian Central Government, and as such are not extendable elsewhere. However, the mechanisms of change examined here may be of wider interest to other public sector organisations.Originality/valueThe paper analyses a real‐world attempt to deploy managerial innovations in the public sector, and the resultant impact. A theoretical framework based on institutional theory and its recent advances is used to better understand the plural factors influencing the use of managerial innovations.
Strategic entrepreneurship: origins, core elements and research directions
Authors: Kyrgidou Lida P. , Hughes Mathew 
Published: January 2010

PurposeThe question of how to integrate strategic and entrepreneurial management to achieve a better balance between advantage‐ and opportunity‐seeking behaviours has received increased academic and practitioner interest in recent years. However, little consensus exists over the meaning of this concept of “strategic entrepreneurship” (SE), its constituents and its operation. This paper aims to address these issues.Design/methodology/approachIn response, the paper reports a thorough review of SE's origins and current conceptualizations to map its core components and charts critical research directions for this exciting emerging field. Analysis of the terrain of SE reveals eight core components drawn from entrepreneurship and strategic management that captures conditions necessary for its application.FindingsFrom this analysis, the paper offers an alternative model of SE, and charts four key research areas with accompanying research questions to inspire future research. These outcomes offer avenues to further sharpen the understanding of how SE might operate both in theory and practice.Research limitations/implicationsA relative lack of analysis and integration of external factors influencing and shaping the process of SE represents a limitation. Also, whilst the authors have attempted to review, assess and understand its position in the entrepreneurship and strategic management literature, the full range of its strengths and weaknesses cannot be grasped.Originality/valueThe paper illustrates how these four question areas pose significant promise to better understand the development and application of SE in research and in practice.
