Authors: Sadat‐Moosavi Ali , Isfandyari‐Moghaddam Alireza , Tajeddini Oranus 
Published: March 2012

PurposeThis research aims to study the state of online resources cited in scholarly library and information science (LIS) journals which are ranked in ISI and available in the Emerald database in terms of accessibility and decay.Design/methodology/approachFour LIS journals published by Emerald were selected from Thomson Reuters' JCR. The journals' issues from 2005 to 2008 were downloaded directly from the publisher web site and checked in terms of decay and availability of individual cited URLs.FindingsOriginal accessibility of studied online resources was 64 percent, which improved to 95 percent. The main adopted strategies that returned more results were using the Wayback Machine and Google, which revived online resources by 17 percent and 12 percent respectively.Practical implicationsTo increase the rate of web citations accessibility, some recommendations, including avoiding long URLs, citing documents found in digital collections availability on the web, working through systematic checking of the web citations before publication, getting backup of cited information, using the more stable file formats and domains, and utilizing tools like WebCite®‐enhanced reference and a digital object identifier (DOI®) system are suggested.Originality/valueA study which examines the accessibility and decay of web citations used by authors of articles published in ISI‐ranked LIS journals available in the Emerald database has not been already done. This paper can thus contribute to the knowledge of this field as well as quality of such literature for web content providers and publishers, authors and researchers.
Library service as theatre
Authors: Cherry Jane , Calvert Philip 
Published: March 2012

PurposeLibrarians have traditionally followed a model of service based on a professional ethic. Attempts to introduce a retail model of service have generally met with staff resistance. The study aims to ask librarians about their attitudes to the retail and professional models of service and what they did not like about the retail model.Design/methodology/approachData were drawn from focus groups consisting of experienced reference librarians.FindingsResults suggest that librarians behave differently while front‐stage and backstage. They resist the retail model because it is perceived to replace service based upon knowledge with fake behaviour.Practical implicationsManagers can draw on the results when considering how best to improve the service provided by library staff who prefer the professional model of service over the retail model.Originality/valueThe use of Goffman's theory of dramaturgy has highlighted previously unknown attitudes to service held by reference librarians that will slow or stop the introduction of the retail model of service.
Attitude and heading reference system with acceleration compensation
Authors: Hemerly Elder M. , Maciel Benedito C.O. , de P. Milhan Anderson , Schad Valter R. 
Published: March 2012

PurposeThe purpose of this paper is to employ an extended Kalman filter for implementing an AHRS (attitude and heading reference system) with acceleration compensation, thereby improving the reliability of such systems, since this removes the usual restrictive assumption that the vehicle is undergoing a non‐accelerated maneuver.Design/methodology/approachMARG (magnetic, acceleration and rate gyros) sensors constitute the basic hardware, which are integrated by the Kalman filter. The error dynamics for attitude and gyro biases is obtained in the navigation frame, providing a much simpler approach than usually taken in the literature, since it relies on direct quaternion differentiation. The state vector associated to the error dynamics possesses six components: three are associated to the quaternion error and three concern gyro bias estimates.FindingsThe AHRS is implemented in an ARM (Advanced RISC Machine) processor and tested with experimental data. The accelerated case is treated by two complementary approaches: by changing the noise variance in the Kalman filter, and by obtaining an acceleration information from GPS (global positioning system) velocity measurements. Experimental results are presented and the performance is compared with commercial ARHS systems.Practical implicationsThe proposed AHRS can be implemented with low cost MARG sensors, and GPS aiding, with use for instance in UAV (unmanned aerial vehicle) and small aircrafts' attitude estimation, for navigation and control applications.Originality/valueUsually the AHRS designs employ as states total gyro bias and Euler angles, or quaternion, and do not consider the accelerated case. Here the state is comprised by gyro bias and quaternion error variables, which attenuates the effect of nonlinearities, and two complementary procedures tackle the accelerated case: acceleration correction by using a GPS derived acceleration signal and change in the output noise covariance used by the Kalman filter.

Authors: Wang Yawei , Zhou Weihu , Han Xiaoquan , Wang Zhongyu , Ding Jinbin 
Published: March 2012

PurposeThe purpose of this paper is to describe a strap‐down image stable strategy for multi‐load optoelectronic imaging platform hung below a tethered aerostat.Design/methodology/approachFour two dimension pods, each with a visible light camera, are fixed on the optoelectronic platform. A POS (Position and Orientation System) is used to acquire the attitude rate data of optoelectronic platform, while the data can be coupled to the pods' servo systems through corresponding coordinate rotation, then the motors of pods will adjust the line of sight to the opposite way to keep the stabilization of image exported by visible light camcorders. Simultaneously, two rate gyros are installed at the inner frame of each pod, which are used as a backup to avoid the failure of POS.FindingsUsing one attitude and position measurement system can realize the stabilization of multi optoelectronic pods, which is same as or even better than the ratio gyro stabilization.Research limitations/implicationsAs the tethered aerostat is a flexible body, it is affected a lot by the wind speed and wind direction at the low height (<1,000 m), which leads to the motors of pods always adjust the line of sight to the mechanical limiting of pods.Practical implicationsStrap‐down stabilization technology has been successfully used in the tethered aerostat monitoring platform to surveillance Shanghai World EXPO site. Long time experiments verify the feasible and effective of the multi‐load stabilization technology. The impact on the image by the adjustment of servos is less than 10 percent of the whole view of sight.Originality/valueThe paper introduces a strap‐down stabilization technology for multi‐load tethered aerostat platform, which is more suitable to be applied in the platform of relatively minor attitude change, like the airborne multi‐load platform and multi‐load UAV (unmanned aerial vehicle) platform.

Authors: Zhengfeng Bai , Yang Zhao 
Published: March 2012

PurposeThe purpose of this paper is to establish the dynamics model of spacecraft during deployment of oblique solar panel using Auto Dynamic Analysis of Mechanical System (ADAMS) and to study the attitude motion of the spacecraft system during the oblique solar panel deployment.Design/methodology/approachFor the case of an oblique solar panel on spacecraft, the dynamics virtual prototype model of deployment of oblique solar panels on spacecraft is established and the dynamics simulation is carried out using ADAMS. The effects of solar panel deployment on the attitude motion of spacecraft with different oblique angles are studied and the attitude motion regularities of spacecraft system are discussed. First, the effects on attitude motion of spacecraft are compared between the normal solar panel deployment and oblique solar panel deployment on a spacecraft. Then the attitude motion of spacecraft during the deployment of solar panel with different oblique angles on spacecraft is studied.FindingsThe effects of oblique angle of solar panel deployment on the attitude motion of spacecraft are significant in yaw axis. The bigger the oblique angle, the bigger the changes of yaw angle of spacecraft. However, the bigger the oblique angle, the smaller the changes of roll angle of spacecraft. The effects of oblique angle on pitch angle of spacecraft are slight.Practical implicationsProviding a practical method to study the attitude motion of spacecraft system during deployment of solar panel and improving the engineering application of spacecraft system, which put forward up spacecraft system to the practical engineering.Originality/valueThe paper is a useful reference for engineering design of a spacecraft attitude control system and ground text.
Gathering the fractionated electromagnetic satellites cluster by simulating fish school
Authors: Su Jianmin , Dong Yunfeng 
Published: March 2012

PurposeFractionated satellite clusters need coming together and avoiding crashing with limited random initial relative motion conditions. It is not necessary to keep the invariable configuration. The purpose of this paper is to put forward a control law which simulates organism swarm motion.Design/methodology/approachThe motion of satellites follows three rules: coming together, velocity homology and avoiding crash. According to the rules, three control forces should be applied to satellite individuals. The final control force is the sum of three control forces. Electromagnetic dipole strengths calculation is formulated as nonlinear optimization problem. Considering control strengths have to be got in real time, iterative steps of optimization algorithm are fixed.FindingsA control law which simulates organism swarm motion is put forward. The simulation shows the organism swarm motion simulation control law can keep fractionated satellite cluster coming together and avoiding crash. When iterative steps of optimization algorithm is fixed, the error of solve nonlinear equations is acceptable.Originality/valueThe control law is robust and easy to realize. When electromagnetic satellite cluster need not keep fixed configuration, it is a choice of control law of relative motion.
Effect of the macro‐pore structure on the anodic polarization behavior of porous titanium
Authors: Li Boqiong , Li Zhiqiang , Lu Xing 
Published: March 2012

PurposePorous titanium is used in many bioimplant and electrode applications because of its interconnected pore structure and good corrosion resistance. The purpose of this paper is to study the anodic polarization behavior of porous titanium in different electrolytes and clarify the influences of the porosity and macro‐pore size on the corrosion resistance.Design/methodology/approachThe porous titanium with 10‐70% porosities and average macro‐pore sizes in the range of 100‐500 μm was prepared by the powder metallurgy method using polymethyl methacrylate (PMMA) as a space holder. Electrochemical corrosion tests were performed on porous titanium as well as solid titanium (with the same irregular and isolated micro‐pore structures as that on the interconnected spheroidal macro‐pore walls of porous titanium) in the 0.1 M H2SO4, 1 M NaOH and 0.9% NaCl (37 °C) solutions.FindingsIt was found that porous titanium exhibited an active‐passive transition behavior in the 1 M NaOH and 0.1 M H2SO4 solutions. In contrast, a self‐passivation transition behavior was observed in the 0.9% NaCl solution (37 °C).Originality/valueThe paper demonstrates that both the porosity and macro‐pore size of porous titanium play an important role in determining the corrosion rate, rather than the corrosion potential.

Authors: Sharma Hariom K. 
Published: March 2012

PurposeThe purpose of this paper is to present the results of some corrosion inhibition studies of brass in 3N HNO3 by gemini surfactants.Design/methodology/approachGemini surfactants namely: N‐trimethyl butane‐diyl‐1,2‐ethane‐bis‐ammonium bromide (BEAB), N‐hexane‐diyl‐1,2‐ethane‐bis‐ammonium bromide (HEAB), N‐dodecane‐diyl‐1,2‐ethane‐bis‐ammonium bromide (DDEAB) and N‐hexadecane‐diyl‐1,2‐ethane‐bis‐ammonium bromide (HDEAB) were synthesized in the laboratory and their influence has been investigated for controlling the dissolution of brass in 3N HNO3. Weight loss, potentiodynamic polarization and electrochemical impedance have been employed for the study. Weight loss experiments were performed as per standard method (ASTM, 1987). Potentiodynamic polarization studies were carried out using EG&G PARC potentiostat/galvanostat (model 173), universal programmer (model 175) and X‐Y recorder (model RE 0089) and impedance measurements were carried out with an EG&G PAR (model 5301 A) lock‐in‐amplifier, using an IBM computer.FindingsThe inhibition efficiency for all the gemini surfactants increases with increase in concentrations. The maximum inhibition efficiency of each inhibitor was achieved at 250 ppm concentration. The inhibition efficiency of all the inhibitors decreases on increasing the temperature from 30 to 50°C. The results of potentiodynamic polarization studies revealed that all the compounds were mixed type inhibitors and inhibit the corrosion of brass by blocking the active sites of the metal. The adsorption of the compounds on brass surface in 3N HNO3 has been found to obey the Langmuir adsorption isotherm.Originality/valueThe paper provides information regarding corrosion inhibition of brass in 3N HNO3, the mechanism of the inhibition on the basis of molecular structures of the inhibitors, activation energy and free energy of adsorption.

Pork quality and the role of marketing contracts: a case study of the US pork industry
Authors: Martinez Steve W. 
Published: March 2012

PurposeThis paper aims to provide an assessment of the growth in marketing contracts in the US pork industry as an efficient means to control pork quality and reduce transaction costs.Design/methodology/approachInformation collected from pork quality and safety summits sponsored by the National Pork Producers Council in cooperation with the National Pork Board, published surveys of large packers related to contract use, and 15 contracts submitted by producers to the Iowa Attorney General's Office from 1996 to 2001 were examined. The theoretical framework used combines branches of the industrial organization literature.FindingsThe paper provides information documenting the growing importance of addressing pork quality problems in the 1990s and how marketing contracts between packers and producers can help address these problems. Recognizes their role in reducing transaction costs associated with carcass pricing programs, reducing pork quality measuring costs, providing quality control, and reducing costs of adapting to quality uncertainty.Research limitations/implicationsThe list of contracts examined is a small collection of contracts voluntarily submitted by producers, and pertains to a specific geographic section of the USA. Thus, they may not be representative of the entire industry.Practical implicationsThe paper provides background information on quality issues faced by the US pork industry and a framework for better understanding the potential role of marketing contracts in addressing these issues.Originality/valueThis paper provides rather unique institutional background information on important changes occurring in the US pork industry in the 1990s and the role of the growth in marketing contracts in addressing related pork quality issues over time. Given the proprietary nature of specific contract terms, a small sample of long‐term marketing contracts is analyzed to better understand contract design.
The mandatory EU logo for organic food: consumer perceptions
Authors: Janssen Meike , Hamm Ulrich 
Published: March 2012

PurposeIn July 2010, a mandatory European Union (EU) logo for organic food was introduced to strengthen the organic sector by making the identification of organic products easier for consumers. The present study aims to analyse how consumers in five EU countries view a mandatory EU logo for organic food and to give recommendations for agrarian decision makers and market actors in the organic sector.Design/methodology/approachThe study is based on a combination of qualitative and quantitative methods to provide a comprehensive picture of consumer views. Focus group discussions were conducted with consumers in the Czech Republic, Denmark, Germany, Italy and the UK. A subsequent survey with 2,042 participants was carried out to quantify consumer views on key issues and analyse country differences. Finally, the results of the qualitative and quantitative study were brought together.FindingsWhile the introduction of a mandatory EU logo for organic food was generally welcomed in all countries, trust in the underlying production standards and the inspection system was not very pronounced (except in Italy). The authors conclude that the introduction of the new EU logo should be supported by communication campaigns to make clear what the new logo stands for and remove unfounded consumer concerns regarding the downscaling of standards and the trustworthiness of the inspection system.Originality/valueTo the authors' knowledge, no previous studies exist on consumer views on a mandatory EU logo for organic food. The recommendations drawn from their findings can help to reach the objectives connected with the introduction of the mandatory EU logo.
Consumption of muscadine grape by‐products: an exploration among Southern US consumers
Authors: Duarte Alonso Abel , O'Neill Martin A. 
Published: March 2012

PurposeConsumption of muscadine grapes and their by‐products (e.g. skins, seeds, wine and juice) is often discussed in terms of their alleged health‐ related properties (e.g. high content of resveratrol, phenolics and antioxidants). Almost no information, however, is available from an academic perspective on consumers' association with this food, including their knowledge, actual consumption of muscadines or by‐products they associate with muscadine grapes. This study seeks to add to the limited existing knowledge on muscadine grapes and their by‐products exploring these areas.Design/methodology/approachA sample of consumers from a Southern US town, where muscadine grapes are native, was chosen. A total of 189 participated completing a questionnaire.FindingsOverall, respondents indicated familiarity with muscadine grapes and by‐products (e.g. wine, jams, juice), but predominantly the more mature respondents related much more to those by‐products than the younger consumer groups. Concerning muscadine wines, while 56.6 per cent of respondents were familiar with this product, and 45.5 per cent considered their consumption experience satisfying to very satisfying, 67.7 per cent either never buy them or seldom do so, suggesting very limited attachment with muscadine grapes.Research limitations/implicationsChoosing one single geographic location (a Southern US town) and the number of participants are two limitations of this study.Practical implicationsGiven the importance of muscadine grapes and their by‐products for the Southern region, particularly culturally, traditionally and for consumers in general in terms of beneficial health‐related properties, an argument is made concerning the need to promote this ancient food. The role of the hospitality and tourism sector, government, agricultural and consumer groups is therefore suggested in promoting, marketing and other forms conducive to raising the profile of muscadine by‐products.Originality/valueThe study focuses on a food (muscadines) and environment (the Southern US region) that despite their cultural importance continue to be under‐researched – even ignored – by much of the contemporary consumer behaviour, hospitality and other literature.

Authors: Waikayi Loise , Fearon Colm , Morris Lynn , McLaughlin Heather 
Published: March 2012

PurposeIncreasingly, post credit crunch, organisations are seeking to develop new ways of attracting, recruiting and retaining staff in the UK high street for less or even no financial reward. The aim of this paper is to investigate volunteerism and volunteer management, based on an exploratory case study of two British Red Cross (BRC) shops. It also aims to examine the reasons why people volunteer and why they keep doing so in the context of BRC, as a charitable organisation.Design/methodology/approachAn exploratory case was used to gain an insight into how BRC recruit and retain volunteer staff. This was achieved by interviewing volunteers and the shop management personnel. An overview of BRC structures, strategic direction and views on volunteerism is also developed as part of the case study.FindingsExploratory findings from the research show that people decide to volunteer mainly for a variety of reasons such as social interaction, to carry out work that is valued in the local community and for self‐satisfaction. Volunteer satisfaction is derived from helping BRC to help others and also being part of The Red Cross. Volunteer retention is attributed to a proactive management style in terms of creating a favourable work environment. The shop manager's leadership skills are crucial in establishing a friendly and positive attitude towards volunteers. In addition, youth volunteers are attracted in order to gain work experience and learn new skills.Research limitations/implicationsThe study is exploratory, based on preliminary interview findings from 17 informants in two BRC shops. However, the insight gained helps in understanding the reasons why volunteerism is successful within the BRC.Practical implicationsThe paper can help policy makers reflect and decide on useful tactics and strategy for developing and improving volunteer management within the retail sector.Originality/valueThere is a paucity of literature in relation to retailing and volunteerism and this study contributes to the literature by identifying reasons why this charity has been so successful in attracting and retaining volunteers.
