Prediction of the closed conformation and insights into the mechanism of the membrane enzyme LpxR
Authors: Saunders Graham M , Macdonald Hannah E Bruce , Essex Jonathan W , Khalid Syma 
Published: April 2018

ABSTRACTCovalent modification of outer membrane lipids of Gram-negative bacteria can impact the ability of the bacterium to develop resistance to antibiotics as well as modulating the immune response of the host. The enzyme LpxR from Salmonella typhimurium is known to deacylate lipopolysaccharide molecules of the outer membrane, however the mechanism of action is unknown. Here we employ Molecular Dynamics and Monte Carlo simulations to study the conformational dynamics and substrate binding of LpxR in representative outer membrane models and also detergent micelles. We examine the roles of conserved residues and provide an understanding of how LpxR binds its substrate. Our simulations predict that the catalytic H122 must be Nε-protonated for a single water molecule to occupy the space between it and the scissile bond, with a free binding energy of -8.5 kcal mol-1. Furthermore, simulations of the protein within a micelle enable us to predict the structure of the putative ‘closed’ protein. Our results highlight the need for including dynamics, a representative environment and the consideration of multiple tautomeric and rotameric states of key residues in mechanistic studies; static structures alone do not tell the full story.
The impact of age norms on career transition intentions
Authors: Slay Ferraro Holly , Prussia Greg , Mehrotra Shambhavi 
Published: April 2018

PurposeThe purpose of this paper is to examine how age norms influence the relationship between individual differences, job attitudes, and intentions to pursue career transitions for midlife adults (aged 35 and above). The authors hypothesized that the effects of individual difference variables (i.e. resilience and reframing abilities) on career change intentions in addition to the effects of job attitude (i.e. commitment) on such intentions are moderated by career youth norms (CYN) which the authors defined as perceptions that the typical worker in a career field is younger than midlife.Design/methodology/approachIn all, 206 people comprised the sample which was derived from an online survey. Moderated regression analysis was used to assess the extent to which age norms operated as a moderator of proposed relationships. Control variables were included based on prior research findings.FindingsFindings demonstrated that age norms operate as a significant moderator for midlife adults. Specifically, the relationships between resilience, reframing, and commitment on intentions to pursue alternative careers are moderated by CYNs.Research limitations/implicationsData were collected from a single source and assessed behavioral intentions in place of actual career change choice. Future research should derive data from multiple sources and assess behavior beyond intentions.Practical implicationsIndustry leaders’ stereotypes about the appropriate ages for specific occupations or professions may impact the psychological mobility of midlife workers. Managers may wish to highlight midlife workers with particular skills (e.g. technological savvy), examine recruitment advertising for language that emphasizes youth, and invest in resilience training for aging workers.Originality/valueResearch examining careers at midlife and beyond has extensively discussed age discrimination and stereotypes as potential barriers to professional or occupational change. However, few studies have investigated how age norms and the comparisons people make between themselves and those they believe are occupying the jobs they desire may also pose barriers to career transition.
Does expressing subjectivity in online reviews enhance persuasion?
Authors: Liu Stephanie Q. , Ozanne Marie , Mattila Anna S. 
Published: April 2018

PurposePeople express subjectivity and objectivity in everyday communication, yet little is known about how such linguistic content affects persuasion in electronic word-of-mouth (eWOM). Drawing on the congruity theory and the selectivity model, the present study proposes that the effectiveness of subjectivity/objectivity expressions in an online review is contingent on whether the consumption experience is primarily hedonic or utilitarian, and whether the decision maker is a male or female. Furthermore, this study aims to examine the psychological mechanism that underlies the proposed effects.Design/methodology/approachThis research used an experimental design to test the hypotheses. Four versions of online review stimuli were created. Participants were asked to read the online reviews and to complete a survey.FindingsThe findings indicate that expressing subjectivity (vs objectivity) in online reviews effectively boosts men’s purchase intention in the hedonic context and women’s purchase intention in the utilitarian context. Furthermore, the mediation analysis reveals that perceived relevance of the review is the psychological mechanism explaining the joint effects of linguistic style, consumption type and gender on purchase intention.Originality/valueThis research is the first to examine expressing subjectivity (vs objectivity) as a persuasion strategy in online reviews. Findings of this research add to the growing literature on linguistic effects in eWOM. Furthermore, this research deepens the understanding of conversational norms for hedonic vs utilitarian consumption in consumer-generated content and gender differences in processing online reviews.
A meta-analytic review of hedonic and utilitarian shopping values
Authors: Vieira Valter , Santini Fernando Oliveira , Araujo Clécio Falcao 
Published: April 2018

Purpose
Hedonic and utilitarian shopping values have been researched since the mid-1980s in the fields of marketing, retail and specially on consumer behaviour. A number of studies have found evidence of their effects on satisfaction, buying intention and loyalty, but others have found no such effects or negative results. The purpose of this study is to apply a meta-analytic review on the shopping values.

Design/methodology/approach
This paper presents a meta-analysis of the relationship between hedonic and utilitarian value on shopping response, using 190 studies. The authors also limited their search to the past 19 years (1995-2014).

Findings
The findings are as follows: hedonic shopping value is positively associated with utilitarian, ρ = 0.56; hedonic and utilitarian exhibit positive main effects on satisfaction, buying intention, loyalty, perceived benefits and search for information; in general, these associations are stronger (vs weaker) for utilitarian value; the effect size for the association between utilitarian and buying intention is stronger in the experimental condition and the indirect effect of hedonic on value, loyalty and word-of-mouth by the mediating effect of value.

Research limitations/implications
The authors proposed and found support for the parallel mediating effect. They also observed that not only hedonic and utilitarian shopping values had indirect effects on loyalty and word-of-mouth through perceived value and satisfaction but also both shopping values had different effects depending on the respective mediator. The indirect effects of hedonic values occur because the emotional and psychological circumstances of experience increase the perceived value, influencing consumers’ responses.

Practical implications
Retailers can create specific stores for consumers to attend to their shopping values. For example, the Adidas brand centre in Beijing/China provides the consumer with a unique and interactive retail experience. This kind of concept store and its experience (e.g. tunnel entry and team room) are congruent with shoppers’ hedonic value. Conversely, Nike Factory Store in the USA provides the consumer with a simple and fast retail experience.

Originality/value
The authors provide sufficient evidence that the two dimensions, hedonic and utilitarian value, are positively associated. This result is congruent with Batra and Ahtola (1991), Babin et al. (1994) and Spangenberg et al. (1997). The results support Chiu et al.’s (2005) argument that utilitarian and hedonic are positively associated based on Fishbein and Ajzen’s affect–cognition link and suggested that the instrumental and functional values are related to spontaneous responses that are more subjective and personal.
The modes of music information in a compositional process: a case study
Authors: Pohjannoro Ulla , Rousi Antti Mikael 
Published: April 2018

PurposeThe purpose of this paper is to demonstrate an actual compositional process that entails a diversity of music information modes and describe the way these modes contribute to the creative aspirations of a composer.Design/methodology/approachThe music information typology proposed by Rousi, Savolainen and Vakkari is used as a point of departure for defining the different modes of music-related information. First, relevant music information modes are identified from the composer-informant’s verbal description of a compositional process. Then, their proportions and dynamics are examined.FindingsThe findings suggest that the music information typology may be applied within the context of musical composition, that is, all of its five modes of music information could be identified from the composer’s verbal description of the compositional process. However, two additional significant information modes were identified: shaping music as the third mode of enactive representations and genuine iconic representations.Research limitations/implicationsThe purpose of this case study is not to claim that the results regarding the significance of individual music information modes apply to all compositional processes within diverse genres of music.Originality/valueThis study introduces a new mode of music information indicative of the artistic capacity of expressiveness: shaping musical structures as the third mode of enactive representations was the means whereby the composer made musical structures work for himself and hence created performative power in his music.

The purpose of this paper is to make a pioneering contribution in defining transparency movements.Design/methodology/approachAn exploratory approach has been used utilizing movement-specific professional and scholarly documents concerning 18 transparency movements.FindingsDifferent traditions, ideologies of openness and aspects involving connections between movements have been identified as well as forms of organization.Originality/valueThis is the first attempt at identifying and defining transparency movements as a contemporary phenomenon.
Smart technologies as social innovation and complex social issues of the Z generation
Authors: Roblek Vasja , Mesko Maja , Dimovski Vlado , Peterlin Judita 
Published: April 2018

PurposeThis paper aims to present how contemporary students are self-organizing using smart technologies (ST) and the future social implications of ST. The research model is based on the concepts of the soft system methodology, social systems thinking, innovative smart systems, and cybernetic and knowledge management.Design/methodology/approachThe study contains elements of exploratory and descriptive case studies. Narrative analysis and interpretation of the collected data have been carried out.FindingsStudents mostly use ST to save time when studying and in their free time. Students are surprised by how ST developed and are cautious when imagining how the technology will change and affect their lives. They are concerned regarding several ethical dilemmas of using it, such as privacy and spending time with their loved ones and friends. Students perceive their self-organization in the future as very dependent on the availability of ST in institutional settings (e.g. education and business process) as well as their personal lives. Students discuss their present perceptions about what the future will be and note that social system will be more dynamic in terms of socialization, and loss of personal contact with their friends and family is seen as the main threat.Research limitations/implicationsThe research is qualitative, and the questionnaire was carried out among business students at the Faculty of Economics, University of Ljubljana, Slovenia.Practical implicationsThe paper offers an understanding of the usage of ST among business students. This study provides a road map of a few possible ways for usage of ST among students. The topic is also relevant for human resource managers, technology developers and marketing strategists for their better understanding of the behaviour of young people using ST in professional or private environments.Social implicationsThe findings can be useful for professors in identifying different learning methods that are useful for their students.Originality/valueThe authors offer conceptualizations of ST within the social innovation framework and provide a contemporary understanding young people’s ST usage.
Internal contributions to initiating corporate social responsibility in sport organizations
Authors: Kim Kyungyeol (Anthony) , Byon Kevin K. , Song Hansung , Kim Kyungsik 
Published: April 2018

PurposeThe purpose of this paper is to highlight the role that employees play in helping embed a corporate social responsibility (CSR)-advocated culture into their organizations through a voice behavior. This study examines: first, the effect of employees’ negative perceptions (i.e. persuasion knowledge (PK)) of CSR on voice behavior; second, the influence of employees’ motivational dispositions regarding goals (i.e. promotion focus) on voice behavior; and third, the positive moderating effect of promotion focus in the negative relationship between PK and voice behavior.Design/methodology/approachData were gathered from 168 employees representing all five Korean professional sport organizations at an inaugural sport marketing workshop, a moderated multiple regression analysis was performed to test the hypotheses.FindingsThe results indicated a marginal negative effect of PK on voice behavior and a significant positive effect of promotion focus on voice behavior. Further, it was found that promotion focus played a positive moderating role in the negative relationship between PK and voice behavior.Originality/valueAlthough employees bear much of the burden of and responsibility for enacting ethical and competitive CSR practices, a paucity of the research has addressed their contributions to CSR as internal promoters of the activities. The present study contributes to the CSR literature by focusing on the role of employees in voicing CSR and empirically examining how promotion focus played a positive role in the relationship between PK and voice behavior.
Freedom or bread?
Authors: Adanhounme Armel Brice 
Published: April 2018

Purpose
The purpose of the paper is to question the false dilemma of bread (the social and economic rights) or freedom (the civil and political rights), which amounts to a simplified ambivalent vision either for or against “China in Africa”, in the debate over African workers’ rights in Chinese enterprises. The paper, first underscores the importance of the constraining and enabling institutional conditions by deconstructing this normative approach, and then proposes an alternative institutional approach to address issues pertaining to employment relations.

Design/methodology/approach
In the tradition of deconstructive techniques, the paper draws three lines of institutional resistance to move the “China in Africa” controversy in employment relations beyond its normative approach. These lines of demarcation are an African ethnology as opposed to a Western modernist reference, a postcolonial analysis of power in lieu of liberal hegemony and informality as a legitimate source of legality.

Findings
The paper suggests the Chinese corporate strategy as implemented by managers notably through human resource management practices, the African institutional contexts where the protagonists’ power resources are deployed and the paramount importance of informality in discussing the impacts of Chinese investments on workers’ rights in sub-Saharan Africa.

Originality/value
The paper shows that the disconnect between “good investment” that should improve social and economic rights and “bad employment” that downplays civil and political rights is not a “foreign” (Western or Chinese) issue per se, but a challenge for innovative employment relations that support investment and mind the workplace institutional context.
Storage study of cereal bars formulated with banana peel flour
Authors: Silva Carvalho Vania , Conti-Silva Ana Carolina 
Published: April 2018

Purpose
This paper aims to examine the bioactive compounds and texture properties of cereal bars formulated with banana peel flour during storage.

Design/methodology/approach
Seven cereal bars were produced and stored during 11 months, under vacuum and protected from the light. The total phenolic compounds, the activity antioxidant by ABTS [2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] method, the DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) method expressed as EC50 (concentration required to reduce the original amount of free radicals by 50 per cent) and texture properties were evaluated over the storage period.

Findings
In general, total phenolic compounds decreased during storage (from 4.19 to 1.11 mg GAE. g-1f.w.). Although the total antioxidant activity (ABTS method) increased during the fifth month, it reduced during storage (from 3.41 to 0.30 µmol TE.g-1f.w.); and the EC50 was not modified in many formulations, though it decreased in other formulations during storage period (from 3913 to 19221 g fruit.g-1 DPPH). The force of rupture began to increase in the fourth month (reaching 62.4 N), and hardness began to increase in the ninth month (reaching 444 N). The formulation and time factors influenced the total phenolic compounds, total antioxidant activity (ABTS method), force of rupture and hardness, while EC50 was only influenced by the formulation (p-value = 0.001). A principal component analysis showed that time had little effect on the most important characteristics considered in description of the cereal bars.

Originality/value
Cereal bars can be consumed up to the third month of storage, considering the texture of the products. Moreover, the presence of bioactive compounds in cereal bars depends on the addition of banana peel flour, which it contributes to the insertion of total phenolic compounds and total antioxidant activity in cereal bars, aggregating functional properties in these products.
Quality characteristics of spent hen meat powder incorporated whole wheat breads
Authors: Umaraw Pramila , Chauhan Geeta 
Published: April 2018

Purpose
This paper aims to standardize level of spent hen meat powder incorporation in whole wheat bread without affecting the bread structure.

Design/methodology/approach
Spent hen meat powder at 20, 30 and 40 per cent level was used for substitution of whole wheat flour.

Findings
The results revealed that increasing the level of meat powder brought about significant (p < 0.05) effect on physicochemical parameters, proximate composition, textural profile and instrumental colour values (except hue). The pH, baking loss, carbohydrate content, energy and moisture protein ratio decreased significantly (p < 0.05) with meat powder incorporation. Whereas, moisture, protein, fat, ash and moisture retention values increased significantly (p < 0.05) with whole wheat substitution. Meat powder addition increased all the textural profile parameters significantly (p < 0.05). Redness, yellowness and chroma values also increased significantly (p < 0.05) with replacement of whole wheat flour. Sensory evaluation showed variable effect of higher meat powder incorporation. The colour of crust, crumb and flavour evinced significant (p < 0.05) increase with level of incorporation, while porosity and texture decreased significantly (p < 0.05). The overall acceptability of 30 per cent replacement was the highest.

Research limitations/implications
Storage stability and preservation aspect can be further explored for better shelf life at ambient temperature.

Practical implications
The development of such a product would definitely be profitable to the poultry industry by opening new avenues for under-used spent hen meat and meat processors.

Social implications
Addition of meat not only channels better utilization of spent hen meat but also enhances economical return to farmers and the meat industry; it also helps in accomplishing protein requirement of consumers.

Originality/value
The addition of spent hen meat enhanced the physico-chemical and sensory attributes of the treated groups than control. It is a novel nutritionally rich alternative for regular breads.
The strategic priorities in the materiality matrix of the banking enterprise
Authors: Formisano Vincenzo , Fedele Maria , Calabrese Mario 
Published: April 2018

Purpose
Nowadays, in this highly dynamic and complex context, companies have to act in a socially responsible and sustainable way to survive, creating shared value. The purpose of this paper is to analyse, through descriptive statistics, the elements that Italian banks identify as strategic to increasing their relational and reputational capital and to being in consonance with stakeholder’s expectations.

Design/methodology/approach
This paper investigates the width (number of intermediaries that included the materiality matrix in their non-financial reports) and the depth (number of indicators in the matrix) of the phenomenon to detect the bank’s attention on critical topics for their stakeholders.

Findings
The focus is on materiality matrices in order to detect a correspondence among the significant indicators selected by the banks and those value generators for stakeholders. In the perspective used in this work, property is also a stakeholder; indeed, wanting to use the terminology of the viable systems approach, property represents a relevant supra-system as it is critical and influential for the decision makers.

Research limitations/implications
The main limits are the low number of non-financial reports published by Italian banks, and the little information on the type of stakeholder involved in the building of the materiality matrix.

Originality/value
The originality of this work is multifaceted. Primarily, there are no similar studies in the banking sector. The present work intends to go beyond the studies already in the literature on mapping and stakeholder prioritisation as well as on the identification and selection of material themes. Moreover, having found, during the analysis of the banks’ reports, the heterogeneity of indicators identified as material, for both banks and stakeholders, the same have been traced back to the related stages identified by Carroll in the pyramid of social responsibility.
