Authors: Cai Xiangyu , Lu Jing , Wu Zhenhua , Yang Chunting , Xu Honglin , Lin Zhijie , Shen Yuequan 
Published: March 2013

GNA1162, a predicted lipoprotein fromNeisseria meningitidis, is a potential candidate for a universal vaccine against meningococcal disease caused byN. meningitidisserogroup B. Here, the crystal structure of GNA1162 at 1.89 Å resolution determined by single-wavelength anomalous dispersion (SAD) is reported. The structure of GNA1162 appears to be a dimer in the crystallographic asymmetric unit as well as in solution. The overall structure of the dimer indicates that each monomer inserts its C-terminal α5 helix into the hydrophobic groove of the other molecule. Moreover, the β4 strands of each monomer lie antiparallel to each other and interact through multiple main-chain hydrogen bonds. Through structural comparisons and operon predictions, it is hypothesized that GNA1162 is part of a transport system and assists in transport and reassembly. The crystal structure of GNA1162 sheds light on its possible function and provides potentially valuable information for the design of a vaccine against meningococcal disease.
Preliminary crystallographic analysis of the kinase domain of SAD-1, a protein essential for presynaptic differentiation inCaenorhabditis elegans
Authors: Yan Xiaojie , Shen Yuequan 
Published: March 2013

SAD-1 is a serine/threonine kinase which plays an important role in the regulation of both neuronal polarity and synapse formation inCaenorhabditis elegans. The kinase domain of SAD-1 fromC. eleganswas overexpressed inEscherichia coliBL21 (DE3) cells and purified to homogeneity using nickel–nitrilotriacetic acid metal-affinity, ion-exchange and gel-filtration chromatography. Diffraction-quality crystals were grown using the sitting-drop vapour-diffusion technique from a condition consisting of 1 MCAPSO pH 9.6, 10%(w/v) polyethylene glycol 3350. The crystals belonged to the monoclinic space groupC2, with unit-cell parametersa= 205.4,b= 57.1,c= 71.7 Å, β = 106.1°. X-ray diffraction data were recorded to 3.0 Å resolution from a single crystal using synchrotron radiation.
The utilisation of lucerne (Medicago sativa): a review
Authors: Mielmann Annchen 
Published: March 2013

PurposeThe aim of this review is to focus on the potential utilisation of lucerne which could contribute more effectively to human nutrition and food sustainability. It aims to explore a proposed cycle for the promotion of lucerne for human consumption. Furthermore it seeks to propose lucerne as a potential vegetable and to briefly discuss the chemical composition, protein application, safety and medicinal uses of lucerne.Design/methodology/approachA non‐experimental approach, namely a systematic literature study, was used. During the study searches were done on the scientific databases Science Direct, Sabinet online, Emerald, EbscoHost and SpringerLink. Moreover internet searches were undertaken on the search engine, Google Scholar. Additionally, available textbooks and theses were consulted. Different combinations of keywords as well as synonyms for keywords were used during the searches. Some keywords used included lucerne, alfalfa and legumes.FindingsThe high costs of animal protein have led to a growing interest in the industrial applications of lucerne in developing countries as lucerne is a valuable source of protein, suitable to produce nutritional food for human consumers. The full development of lucerne's potential is hindered by a lack of awareness among consumers as well as by a lack of capacity within a research community. Therefore the key steps in the proposed cycle can be used to aid in the diversification of lucerne in the market place.Originality/valueTo the author's knowledge there exists a lack of previous reviews on lucerne. It is important for scientists to become aware of the nutritional and entrepreneurial potential and contribution for human consumption purposes in the future in order for the lucerne industry to diversify.
A knowledge exchange and diffusion of innovation (KEDI) model for primary production
Authors: Manning Louise 
Published: March 2013

PurposeThis paper seeks to develop a new model for the activities of knowledge exchange (KE) and the diffusion of innovation (DI) with specific emphasis on agriculture.Design/methodology/approachThe research involved an examination of existing literature and the development of the knowledge exchange and diffusion of innovation (KEDI) model.FindingsAs human population rises, there will be a greater focus on KEDI in the agricultural sector. Due to the heterogeneous nature of farming communities around the world, indigenous knowledge (IK), change agents, opinion leaders and farmer‐to‐farmer (F2F) interaction all play a role in KE and technology transfer. The KEDI whirlpool model seeks to reflect these dynamics by highlighting the interacting drivers and the process required to deliver outputs such as supply chain agility, reduced costs, and more efficient use of resources, knowledge and assets.Originality/valueThis research is of academic value and of value to those working in the food supply chain.
Migrants as ascenders: reflections on the professional success of migrant apprentices
Authors: Magdaalena Stamm Margrit 
Published: March 2013

PurposeThe aim of this article is to explore the phenomenon of gifted migrants in vocational training and education. To date, migrant apprentices have been predominantly discussed from a deficit perspective. Special attention has been given to competence insufficiency and underperformance, as well as to migrant adolescents’ lack of professional and educational attainment. However, recent research points to a social group of migrants who are successful educational and professional achievers.Design/methodology/approachThe article at hand discusses five theoretical models commonly applied to explain underachievement among migrant adolescents. It then examines these models’ explanatory power to predict migrants’ educational success. To conclude, the research parameters and theoretical framework of a Swiss longitudinal study designed on the basis of these findings is presented.FindingsEducational research has increasingly focused on migrants, as well as on vocational education and training. However, what resulted from existing research is a predominantly unfavorable image of migrant apprentices that exclusively portrays them as so called “educational losers” of socio‐economically and culturally disadvantaged backgrounds. Based on theoretical explanatory models, a number of assumptions were extracted to show how educational success among migrants could be explained and whether resilience factors play a role in it. From the resilience perspective, professional success of migrant apprentices is likely to result from a stable, long‐term attachment figure or mentor who served as a role and identification model and was of significant importance in the adolescents’ workplace, for example as professional mentor. Furthermore, it is expected that educational facilities, in particular vocational training institutions, must have excelled in demanding high educational achievement, providing clear organizational and management structures, and high teaching quality as well as good instructor‐learner relationships.Originality/valueAs has been shown, educational research has increasingly focused on migrants, as well as on vocational education and training. However, what resulted from existing research is a predominantly unfavorable image of migrant apprentices that exclusively portrays them as so called “educational losers” of socio‐economically and culturally disadvantaged backgrounds. This implies that educational and professional success is not attainable for youths from disadvantaged families. On the other hand, successful migrant careers have been exemplarily portrayed; systematic research however is scarce and virtually non‐existent in German‐speaking academia. The lack of educational policy debate about successful migrants is probably a result of this research gap.

Authors: Cherukodan Surendran , Santhosh Kumar G. , Humayoon Kabir S. 
Published: March 2013

PurposeThe purpose of this paper is to describe the design and development of a digital library at Cochin University of Science and Technology (CUSAT), India, using DSpace open source software. The study covers the structure, contents and usage of CUSAT digital library.Design/methodology/approachThis paper examines the possibilities of applying open source in libraries. An evaluative approach is carried out to explore the features of the CUSAT digital library. The Google Analytics service is employed to measure the amount of use of digital library by users across the world.FindingsCUSAT has successfully applied DSpace open source software for building a digital library. The digital library has had visits from 78 countries, with the major share from India. The distribution of documents in the digital library is uneven. Past exam question papers share the major part of the collection. The number of research papers, articles and rare documents is less.Originality/valueThe study is the first of its type that tries to understand digital library design and development using DSpace open source software in a university environment with a focus on the analysis of distribution of items and measuring the value by usage statistics employing the Google Analytics service. The digital library model can be useful for designing similar systems.

Determinants of bank selection in the United Arab Emirates
Authors: Sayani Hameedah , Miniaoui Hela 
Published: March 2013

PurposeThis study aims to identify the determinants of bank selection for Islamic and conventional banks in the United Arab Emirates (UAE).Design/methodology/approachData were collected from 246 respondents in the Emirates of Dubai and Sharjah and focused on aspects such as bank products, service quality, profit, reputation, cultural and religious factors, in addition to demographic attributes of the sample. Multiple discriminant analysis is used to identify the most important determinants of bank selection.FindingsThe study concluded that the determinants for bank selection are more distinguishable amongst Islamic bank customers. Bank reputation and expectation of profit on deposits are not determinants of bank selection; however, religious preferences are the most important considerations in selection between Islamic and conventional banks.Research limitations/implicationsUse of convenience sampling due to lack of resources may result in insufficient representation of population. Additionally, analysis of differences between the Muslim and non‐Muslim population with respect to their bank selection process may provide an avenue for future research.Practical implicationsThe study has implications for both Islamic and conventional banks that can appropriately target the customers using bank selection determinants that are valued by the customers.Originality/valueThe study adds to the existing literature on consumer preferences for Islamic and conventional banks in the context of the UAE with a relatively large and recent data set.

Revisiting the role stress‐commitment relationship
Authors: Ackfeldt Anna‐Lena , Malhotra Neeru 
Published: March 2013

PurposeThe purpose of this paper is to investigate the moderating influences of empowerment and professional development on role stress‐commitment relationships, while examining and confirming the effects of role stress on organisational commitment.Design/methodology/approachThe results are drawn from a cross‐sectional survey of 184 front‐line employees (FLEs) from a travel service organization. Multiple and moderated regression analyses were employed to test the hypothesised direct and interaction effects.FindingsThe results show that role stressors influence affective organizational commitment in FLEs negatively. Role ambiguity did not, unexpectedly, influence continuance commitment positively, but role conflict did. Professional development and empowerment are important management tools that can be used to combat the detrimental effect of role stress on organizational commitment. The paper finds empowerment to be particularly useful in combating the dysfunctional effects of role ambiguity on affective commitment, while professional development is a key tool that helps to combat the dysfunctional effects of role conflict on affective and continuance commitment. However, there are caveats associated with the implementation of these management tools.Practical implicationsIt is important for management to understand role stress from the FLE perspective, and strategically use intervention tools to help moderate the effects of role stress on organizational commitment components.Originality/valueThis study adds further support to the literature that role ambiguity and role conflict should be studied as distinct components of role stress because treating role stress as a single construct may result in suboptimal outcomes for managers, and misleading findings for researchers. In this context, the paper contributes to literature by investigating the moderating impact of empowerment and professional development on the role stress‐affective commitment/continuance commitment relationships. The findings suggest that different managerial strategies are required to combat the effect of each of these role stressors on the affective and continuance components of commitment respectively.
Constructing luxury brands: exploring the role of consumer discourse
Authors: Roper Stuart , Caruana Robert , Medway Dominic , Murphy Phil 
Published: March 2013

PurposeThe aim of this paper is to offer a discursive perspective on luxury brand consumption.Design/methodology/approachDiscourse analysis is used to examine how consumers construct their luxury brand consumption amidst countervailing cultural discourses in the market (Thompson and Haytko). Consumer discourse is generated through in‐depth, semi‐structured interviews.FindingsIn the context of countervailing discourses that challenge the notion of luxury (e.g. “masstige”, “chav” and “bling”), respondents construct an ostensibly distinct and stable version of luxury expressing its subjective, experiential, moral and artistic constructs. Analysis demonstrates how these four themes operate at a linguistic‐textual level to delineate important cultural categories and boundaries around luxury. Luxury brand discourse operates strategic juxtapositions between normatively positive (ideal) and normatively negative (problematic) categories, which are paradoxically interdependent.Research limitations/implicationsA qualitative study of high‐income residents from an affluent UK region is reported upon. The study is exploratory, focussing on interrelations between discourse, content and context. This invites future studies to consider contextual elements of luxury branding.Originality/valueThe paper proposes a new way of thinking about luxury brands as a socially constructed concept. The paper concludes by arguing that luxury brand management necessitates a deeper appreciation of the mechanics of consumers' luxury discourses.
A grounded theory of the corporate identity and corporate strategy dynamic
Authors: He Hong‐Wei , Balmer John M.T. 
Published: March 2013

PurposeThis article has an explicit purpose of making a theoretical contribution to the issue of senior management cognitions of the corporate identity/corporate strategy interface. The aim of this research is to particularise the nature and saliency of this interface to corporate marketing scholars and practitioners alike.Design/methodology/approachThis article adopts a grounded theory methodology and is informed by three in depth case studies undertaken among three building societies (mutuals) operating within the British Financial Services Industry.FindingsThe results confirm the saliency of the corporate identity/corporate strategy dyadvis‐a‐visthe comprehension and management of contemporary organisation. Theoretically, the study finds that senior management's cognitions of the corporate identity/strategy interface are interdependent, symbiotic and dynamic in nature: the nature of the dyad differed among the three institutions examined. In terms of the nascent domain of corporate marketing, this study confirms the extant literature, which suggests that, in addition to comprehending the psychology of customers and other stakeholders, the psychology of senior managers is also highly germane.Practical implicationsWithin corporate marketing contexts, organisations should be mindful of the critical importance of the corporate identity/strategy interface; a concern for the above should be an important part of their corporate marketing as well as regulatory and strategic deliberations. However, senior managers should note the inherent dangers to identity maintenance where material alignment between corporate identity and strategy is ignored and where cognitive alignment is adopted as a surrogate: the former entails a synchronisation of facts whereas the latter entails the calibration of beliefsvis‐à‐viscorporate identity and strategy.Originality/valueThis is a major theory‐building study, which examines managerial cognitions of the corporate identity/strategy interface and a major study of its type within the British Building Society sector.
Will normal‐sized female models in advertisements be viewed as positively as small‐sized models?
Authors: Bian Xuemei , Foxall Gordon 
Published: March 2013

PurposeDespite the call from the public domain to use normal‐sized models (NM) in advertising and the fact of the recent movement in the practitioner's domain concerning the use of NM, knowledge of the advantages/disadvantages concerning the use of NM in comparison to small‐sized models (SM) is lacking. Prior research indicates that framing changes attitudes by altering the underlying considerations used in one's evaluation, but there are few studies that test framing effects on consumers' judgments of commercial persuasion. Moreover, an actionable understanding of the brand effects on consumers' model evaluation remains unexplored. The purpose of this paper is to address these unresolved issues.Design/methodology/approachIn two studies, the paper examines the effects of different instructional frames on consumers' evaluation of NM as opposed to SM for new brands. The paper also examines how and to what extent brand effects of established brands might alter the effects of instructional frame on NM and SM evaluations. Furthermore, the paper investigates the direct and indirect impact of consumers' health‐consciousness concerning SM on the results. Research findings are discussed.FindingsThe present research shows that considering instructional frame and brand effect offers insights into consumers' model evaluations.Originality/valueThis research contributes to literature by bridging four knowledge gaps. First, this research is one of the few which investigated consequences resulting from using NM. Second, knowledge of comparative advantages/disadvantages in the relationship to the use of unconventional models versus SM was lacking until the present research. Third, this research is one of the few which provides empirical evidence of framing effects on consumers' judgment of commercial persuasion. Fourth, brand effects on consumers' model evaluations were unknown until the current research.
Configural algorithms of patient satisfaction, participation in diagnostics, and treatment decisions
'
influences on hospital loyalty
Authors: Chang Chia-Wen , Tseng Ting-Hsiang , G. Woodside Arch 
Published: March 2013

Purpose
– This empirical study aims to explore sufficiency conditions for patient loyalty to a hospital.

Design/methodology/approach
– The study collected 645 self-administered questionnaires from patients in a major medical center in Taiwan and applied fuzzy set qualitative comparative analysis (fs/QCA) to explore the sufficiency conditions for patient loyalty.

Findings
– The findings support the conclusion that the three conditions (patient satisfaction, patient participation in the process of diagnosis, and patient participation in treatment decision-making) in combination are sufficient for high patient loyalty to the hospital but high patient satisfaction alone is insufficient. While the three conditions in configural algorithm are sufficient, this expression is not necessary, which means the findings do not reject possible alternative conditions for high patient loyalty.

Research limitations/implications
– The study applies a relatively new method, fuzzy set qualitative comparative analysis (fs/QCA) to test the sufficiency proposition of the theory. This method enables researchers to focus on examining sufficient conditions without worrying about various confounding factors and informs this study
'
s conclusion that patients exhibiting high scores in all three conditions mentioned above constitute a near-perfect subset of highly loyal patients. Hospitals thus should provide their satisfied patients opportunities to share a role in the process of diagnosis and treatment decision-making.

Originality/value
– Along with patient satisfaction, this study clearly identifies two important stages of patient participation (i.e., participation in the process of diagnosis and treatment decision-making) that are important in forming patient loyalty to a hospital. Prior studies do not present empirical evidence to this proposition.
