Authors: Fasoyiro S.B. , Ajibade S.R. , Omole A.J. , Adeniyan O.N. , Farinde E.O. 
Published: July 2006

PurposeAfrican yam bean (Sphenotylis stenocarpa), bambara groundnut (Vigna subterranean), pigeon pea (Cajanus cajan) and lima bean (Phaseolus luunatus) are some of the minor grain legumes found in Nigeria. Their utilization has been very limiting because little is known about their nutritive value. The proximate, minerals and antinutritional factors of two collections of African yam bean, lima beans and pigeon pea, and one collection of bambara groundnut seeds grown in south‐western Nigeria were studied.Design/methodology/approachDry seeds of two collections of African yam bean, pigeon pea and lima beans, and a collection of bambara groundnut were collected from Oyo and Ondo States in south‐western Nigeria. The legumes were sorted, milled and stored in polythene bags at 4°C.FindingsThe crude protein in the legumes was in the range of 22–37 per cent, crude fat 1.47–4.96 per cent, crude fibre 1.92–7.21 per cent and ash 3.33–5.61 per cent. K, Ca and P were in the range of 0.15–0.52 per cent. Iron content of the seeds was very low. The antinutrients, tannin, phytic acid and trypsin inhibitor were very high when compared to those of cowpea, groundnut and soybean.Originality/valueIt therefore implies that consumption of these legumes will require processes that will reduce their antinutritional factors.
Shelf‐life extension of cultured milk products
Authors: Sarkar S. 
Published: July 2006

PurposeShelf‐life of cultured milk products is longer than milk but it is still limited. Shelf‐life of cultured milk products could be enhanced by adopting various techniques. The purpose of this paper is to describe how the longer shelf‐life thus attained would extend the market reach and would be economically beneficial to both producers and consumers.Design/methodology/approachAttempt has been made to enlighten the various techniques such as bacteriocin (nisin, MicrogardTM, natamycin, etc.), lactoperoxidase‐thiocyanate‐hydrogen peroxide system (LP‐system), high pressure treatment, post‐production heat‐treatment (thermization, microwave heating), ultra‐violet (UV) irradiation, carbonization, etc.FindingsApplication of more than one bacteriocin may be advantageous to minimize the possibility of survival of microflora resistant to a particular bacteriocin. Pasteurization, being more detrimental to dietetic properties of cultured milk products than thermization, its application is not suggested as a method of preservation. Microwave heating may be better than conventional pasteurization.Originality/valueConjugated application of various techniques would be more efficacious in extending the shelf‐life of cultured milk products. Extension in shelf‐life of cultured milk products would be economically beneficial for producers and consumers.
Colour stability and vitamin C retention of roselle juice (Hibiscus sabdariffa L) in different packaging materials
Authors: Aina J.O. , Shodipe A.A. 
Published: July 2006

PurposeIn Nigeria, roselle juice is quite popular among the populace presumably owing to its attractive colour, pleasant flavour and nutritional attributes. In the citrus industry, processing and packing material selection have significant effect on quality of juice product during storage. The effects of packaging materials, and storage temperature on colour and vitamin C retention of sobo juice extracted from local roselle plant were investigated.Design/methodology/approachJuice was extracted at three different temperatures: 20, 60 and 100°C for varying processing times of 5, 10, 15, 20 and 25 min respectively. Freshly extracted roselle juice was divided into three batches and independently hot‐filled into 500 mL pre‐sterilised glass, film packages and polyethylene terephthalate (PET) bottles allowing for minimum head space, capped, cooled and subsequently stored at 5 ± 1 and 28 ± 1°C respectively for eight weeks.FindingsOptimum pigment extraction was obtained in 20 min with boiling water, while colour stabilisation of the extracted juice was affected with the use of food acidulants. Colour degradation on storage was pronounced in sweetened juice with greater colour loss in product held at ambient temperature. Colour and vitamin C retention with glass and plastic bottles provide higher retention of these quality attributes under cold and ambient storage condition than with the flexible polyethylene film.Originality/valueRetention of colour and vitamin C was considerably higher in glass and PET bottles than in flexible film package. However, addition of table sugar or increasing storage temperature from 5 to 27°C affected colour stability.
Dietary supplements for phenylketonuria: removing Phe by activated carbon
Authors: Cristine Fialho Lopes Daniella , Meneghello Delvivo Fernanda , Pinto Coelho Silvestre Marialice 
Published: July 2006

PurposeThis paper aims at testing several conditions using activated carbon for removing phenylalanine (Phe) from protein hydrolysates, in order to prepare dietary supplements for phenylketonurics, based on skim milk.Design/methodology/approachSix hydrolysates from skim milk were prepared, using a protease from Aspergillus oryzae (AO), isolated or in association with papain (PA). Some parameters were tested for removing Phe, such as amount of activated carbon, temperature and stirring time. The second derivative spectrophotometry was used to evaluate the efficiency of Phe removal.FindingsThe best condition for removing Phe was achieved using an activated carbon: casein ratio of 118 (in g), a stirring time of 30 min, at a temperature of 25°C, which produced 96 to 99 per cent of Phe removal. Among the hydrolytic conditions employed, the association of AO and PA (1 hour, 1 per cent and 4 hours, 2 per cent, respectively) led to the lowest absolute value for the final Phe concentration (0.060 × 10−4 mg/100 mg of protein).Original/valueSince we know, there is no formula for PKU on the market based on skim milk hydrolysed proteins. Isolated casein, the main milk protein, is the choice in most cases. This is a factor that may be taken in consideration especially in developing countries, where milk proteins are imported and, consequently, are much more expensive than skim milk.
A neural predictor to analyse the effects of metal matrix composite structure (6063 Al/SiCp MMC) on journal bearing
Authors: Sinanoğlu Cem 
Published: July 2006

PurposeTo discuss the effects of metal matrix composite (MMC) journal structure on the pressure distribution and, consequently, on the load‐carrying capacity of the bearing are predicted using feed forward architecture of neurons.Design/methodology/approachThe inputs to the networks are the collection of experimental data. These data are used to train the network using the Batch Back‐prop, Online Back‐prop and Quickprop algorithms.FindingsThe neural network (NN) model outperforms the available experimental model in predicting the pressure as well as the load‐carrying capacity.Research limitations/implicationsThe experiment specimens used in this study have been made of MMC with aluminum based reinforced with SiC ceramic particles, using the stir casting technique. Various composite journal structures can be investigated.Practical implicationsThe simulation results suggest that the neural predictor would be used as a predictor for possible experimental applications on modelling journal bearing system.Originality/valueThis paper discusses a new modelling scheme known as artificial NNs. An experimental and a NN approach have been employed for analysing MMC journal structure for hydrodynamic journal bearings and their effects on the system performance.
Analytical solution for two‐dimensional Reynolds equation for porous journal bearings
Authors: D'Agostino V. , Senatore A. 
Published: July 2006

PurposeAims to explore many aspects of the dynamic behaviour of a rotor on bearings, such as the fluid film force. In order to find in an analytical model an effective solution to provide a more readable description of the interaction between journal and bearing.Design/methodology/approachThe present theoretical analysis is carried out to determine the analytical approximate formulation of the fluid film force of porous finite journal bearings. This paper focuses on an approximate mathematical model for the one‐dimensional lubrication equation about the infinitely long porous journal bearing, while the Warner's method is adopted to describe the oil film pressure film in the finite bearing domain.FindingsThe proposed model allows a quick analytical determination of the fluid film force for different values of the permeability coefficient, L/D ratio, eccentricity ratio. The results are in good agreement with those achieved by means of the FDM based solution.Originality/valueThe results show good agreement over the typical parameter ranges of the operation on this kind of tribological components.
Temporary agency work and HRM in Australia
Authors: Hall Richard 
Published: July 2006

PurposeThe purpose of this paper is to examine the management of agency workers in Australia and, in particular, to identify the challenges presented to HRM by agency work.Design/methodology/approachAfter briefly reviewing the data on the incidence and growth of agency work in Australia, this paper examines the role of agency work in Australia from the perspective of the industry. Then it reviews both the evidence concerning the reasons for client organisations using agency workers and the attitudes of agency workers to their work. The paper concludes by assessing the implications of these findings for both for HR managers and HRM in general.FindingsWhen the attitudes and preferences of agency workers are compared with those of direct employees it is found that agency workers are no more satisfied with their level of flexibility than direct workers and are in fact less satisfied with their job security, skill utilization and development, pay, autonomy and influence at work. Given these findings, it is argued that agency work may be incompatible with HR strategies that are based on high performance work practices.Originality/valueThis article gives helpful advice to HR managers in any organization that are in the market for agency workers.
Evaluating public web site information: a process and an instrument
Authors: Judd Vaughan C. , Farrow Lucy I. , Tims Betty J. 
Published: July 2006

PurposeThe purpose of this paper is to discuss the attempt to find an evaluation instrument for undergraduate students to use to evaluate public web sites, the analysis of the variety of instruments discovered, the subsequent development of an appropriate instrument, and the application of the instrument in workshops with students.Design/methodology/approachThe instrument was created based on the following criteria that the authors determined would meet the students' needs. It focuses exclusively on the information aspect of a web site, has some basis in theory or is based on an accepted model, is parsimonious, is quantitative, with both absolute and relative measures, and indicates whether or not the information should be accepted or rejected. The instrument was also developed with the goal of focusing on the process rather than the outcome.FindingsAlthough a number of diverse evaluation instruments from the literature and from web‐based sources were examined, none was deemed suitable for students to use so the authors developed their own.Originality/valueThe authors concurred that, based on their assessment of the learning environment, the focus of an instrument should be on evaluation as a process.

Authors: Rockman Ilene F. 
Published: July 2006

PurposeThe purpose of this paper is to reflect upon the journal, Reference Services Review, since the editorship of Ilene F. Rockman began in 1986.Design/methodology/approachThe paper describes how the journal has become one of the most respected in its profession, has encouraged new authors and published several ground‐breaking articles over the past two decades.FindingsThe journal's standard of excellence is high and continues to model a commitment to, and passion for, reference services and collections, utilization of technology to help users and innovation in library instruction and information library programs.Originality/valueThe paper offers a reflection of RSR and its contribution toward equity and social responsibility.
Net cred: evaluating the internet as a research source
Authors: Doyle Tony , Hammond John L. 
Published: July 2006

PurposeThe purpose of this paper is to show how web sites can be a valuable research source for students if approached with due caution.Design/methodology/approachThis article is the product of collaboration between a sociology professor and a librarian. The authors discuss the nature of their collaboration and present their views on web evaluation in the context of an extensive literature review.FindingsReputable print sources have numerous mechanisms to help ensure reliability: proven authors and editors, track record, and (sometimes) peer review. Obviously, the vast majority of web sites lack these features. Accordingly, the paper offers a critical look at the standard criteria of web evaluation with illustrations from two sites, one credible, one not.Originality/valueHealthy skepticism regarding the internet is urged. It is suggested that web evaluation has costs and benefits. The chief benefit of careful web site evaluation is that the process makes it more likely than otherwise that one will wind up with reliable sites. The main cost is that evaluation takes time, and the value of a given piece of information declines according to the effort one spends verifying it. A second potential cost is that undue skepticism can prompt one to dismiss perfectly respectable sites.
Reference services in digital collections and projects
Authors: Choi Youngok 
Published: July 2006

PurposeThe purpose of this study is to examine the extent to which digital library projects incorporated reference services to increase the value of the collections and support the use of information.Design/methodology/approachAfter defining digital library service types, the study surveyed 60 digital collections/projects from the Digital Initiatives Database (DID) and analyzed what types of services have been offered and how they varied.FindingsFindings showed that digital collections scored high marks in offering services in two areas – search and digital reference; however, the findings also revealed that they have been limited in giving valuable information services in other areas.Originality/valueThe study shows that the current practice of digital initiatives needs to integrate various services not only to help users find information, but also to instruct users to better utilize the library and its other services.

Authors: Funk Debby , Oly Ndubisi Nelson 
Published: July 2006

PurposeResearch in to how colour can stimulate interest and subsequently increase the appeal power of products. There has been very little or no research in the colour‐impact domain in Malaysia. Gender has also been presented as an important factor of colour penchant and proclivity. Seeks to understand the influence of colour on consumer choice of automobile as well as the effect of gender differences.Design/methodology/approachA field survey of Malaysia consumers was conducted to understand these influences. A total of 196 consumers randomly selected from a mall intercept exercise responded to the questionnaire.FindingsShows that attitude towards colour, colour attractiveness, normative colour, and colour preferences are significantly associated with product choice. The results also show that gender moderates the impact of colour significance, attitude towards colour, colour attractiveness, and colour preferences on choice.Research limitations/implicationsLimited by the fact that the study was undertaken in one country.Practical implicationsTo help marketers exploit gender differences through use of colour.Originality/valueThere has been little research on colour in marketing in the past. This fills a gap.

Authors: Oly Ndubisi Nelson , Koo Jenny 
Published: July 2006

PurposeAddresses the impact of family structure on joint purchase decisions of Malaysian spouses for the following products: furniture, vacation, and aggregate or overall products (a combination of furniture and vacation).Design/methodology/approachA total of 103 couples responded to the survey conducted in Kota Kinabalu, Malaysia, to understand the impact of family typing namely, strong vs weak cohesive family and modern vs traditional family on joint purchase decision on furniture, vacation, and aggregate products.FindingsThe outcome shows consistent results across the three products as follows: a strong cohesive family makes more joint decisions on furniture than a weak cohesive family and a modern family makes more joint decisions on furniture than a traditional family; a strong cohesive family makes more joint decisions on vacation than a weak cohesive family and a modern family make more joint decisions on vacations than a traditional family; and a strong cohesive family makes more joint decisions on aggregate products than weak cohesive family and modern family makes more joint decisions on aggregate products than a traditional family.Practical implicationsSupports the preponderance of strong cohesive families over weak in making joint decisions on furniture, vacations and both.Originality/valueModern families make more joint purchase decisions than traditional families.
Evaluation of transitional mentoring for new library and information professionals
Authors: Hallam Gillian , Newton‐Smith Carol 
Published: July 2006

PurposeTo present the findings of the comparative evaluation of two transitional mentoring programs developed for new library and information professionals in Australia, one as a group program and the other with pairs of mentors/mentees.Design/methodology/approachThe research project involved an initial review of the literature. A comparative study was undertaken, with a survey approach to collect data from the participants in the transitional mentoring programs. The study obtained data about three key areas: career‐related, learning‐related, and professional development.FindingsIt was found that participants had a high level of satisfaction with both the programs and both mentor and mentee reported positive career, learning and personal development outcomes.Research limitations/implicationsThe study was limited to one year of transitional mentoring activity for one professional field in Australia. It would be beneficial to continue the study over a longer period of time to collect further data from other participants.Practical implicationsThe research project highlights evaluation of mentoring programs. The project has helped develop an initial understanding of benefits to be gained through mentoring relationships to support new professionals. The study is likely to have wider application across other professional disciplines and may encourage professionals to consider mentoring as a valuable part of career development.Originality/valueThe paper provides information about two different models of transitional mentoring programs, together with one possible approach for the evaluation of mentoring programs. The paper offers support and encouragement to any professional group planning to establish and manage a mentoring program.
Negotiator style and influence in multi‐party negotiations: exploring the role of gender
Authors: Karakowsky Leonard , Miller Diane L. 
Published: July 2006

PurposeThe extant literature suggests that men and women do not necessarily possess identical negotiating styles. However, unfortunately the literature has yet to clearly identify the role that gender plays in the negotiation context and in the behaviours of male and female negotiators. This paper aims to contribute to understanding of this topic.Design/methodology/approachConceptual/theory paper (with relevant literature reviews).FindingsPerceived power in a multi‐party negotiation can be affected by numerical status, as well as social status with the result that a minority female in a group dominated by males will act differently from a male in a female‐dominated group.Research limitations/implicationsThis paper draws on theories of proportional representation, social roles and perceived status, in order to identify a number of factors that can affect the degree of influence exerted and the behavioural style adopted among male and female negotiators in mixed‐gender, multi‐party business negotiations.Practical implicationsThis paper explores a very practical question – do men and women behave differently at the “bargaining table”? And how does gender play a role in multi‐party negotiations?Originality/valueThis study is highly original, given the lack of theory in this area.
Environmental leadership development
Authors: Vardiman Phillip D. , Houghton Jeffery D. , Jinkerson Darryl L. 
Published: July 2006

PurposeThe purpose of this article is to provide a basis for comparing the interactions between the level of environmental support for leadership development and individual leadership characteristics in determining leadership selection and effectiveness within organizations.Design/methodology/approachA contextual model of leader selection and effectiveness examining the interactions between the level of environmental support and individual leadership characteristics to predict specific research propositions based on organizational needs is presented. The paper first provides an overview of leadership selection and effectiveness research and then illustrates a contextual model of leadership selection and effectiveness. The model design is based on a four‐quadrant structure with two propositions being suggested for each quadrant.Findings– Describes the context and proposed outcome of each respective quadrant for identifying and selecting potential leadership talent within an organization. The model also highlights the tendencies of organizational leadership to promote or select potential leadership talent from predictable employee groups based on how they match preconceived expectations.Research limitations/implications– The model has not yet been tested empirically.Practical implications– A very useful approach for organizations looking to improve their internal leadership development capabilities and leadership selection processes. This model lays the foundation for leadership identification and selection from all areas of an organization while emphasizing the necessity for leadership development at all levels.Originality/value– All organizations face the challenge of leadership identification, growth, development and effectiveness. This paper offers insights into understanding how leaders are identified for growth and development within an organization and how individuals within those organizations perceive themselves participating in leadership opportunities.
