Probing the effects of nonannular lipid binding on the stability of the calcium pump SERCA
Authors: Espinoza-Fonseca L. Michel 
Published: November 2018

AbstractThe calcium pump SERCA is a transmembrane protein that is critical for calcium transport in cells. SERCA resides in an environment made up largely by the lipid bilayer, so lipids play a central role on its stability and function. Studies have provided insights into the effects of annular and bulk lipids on SERCA activation, but the role of a nonannular lipid site in the E2 intermediate state remains elusive. Here, we have performed microsecond molecular dynamics (MD) simulations to probe the effects of nonannular lipid binding on the stability and structural dynamics of the E2 state of SERCA. We found that the structural integrity and stability of the E2 state is independent of nonannular lipid binding, and that occupancy of a lipid molecule at this site does not modulate destabilization of the E2 state, a step required to initiate the transition toward the competent E1 state. We also found that binding of the nonannular lipid does not induce direct allosteric control of the intrinsic functional dynamics the E2 state. We conclude that nonannular lipid binding is not necessary for the stability of the E2 state, but we speculate that it becomes functionally significant during the E2-to-E1 transition of the pump.
Quantum-entanglement pigeon-inspired optimization for unmanned aerial vehicle path planning
Authors: Li Siqi , Deng Yimin 
Published: November 2018

Purpose
The purpose of this paper is to propose a new algorithm for independent navigation of unmanned aerial vehicle path planning with fast and stable performance, which is based on pigeon-inspired optimization (PIO) and quantum entanglement (QE) theory.

Design/methodology/approach
A biomimetic swarm intelligent optimization of PIO is inspired by the natural behavior of homing pigeons. In this paper, the model of QEPIO is devised according to the merging optimization of basic PIO algorithm and dynamics of QE in a two-qubit XXZ Heisenberg System.

Findings
Comparative experimental results with genetic algorithm, particle swarm optimization and traditional PIO algorithm are given to show the convergence velocity and robustness of our proposed QEPIO algorithm.

Practical implications
The QEPIO algorithm hold broad adoption prospects because of no reliance on INS, both on military affairs and market place.

Originality/value
This research is adopted to solve path planning problems with a new aspect of quantum effect applied in parameters designing for the model with the respective of unmanned aerial vehicle path planning.
The impact of self-congruity (symbolic and functional) on the brand hate
Authors: Islam Tahir , Attiq Saman , Hameed Zahid , Khokhar Munnawar Naz , Sheikh Zaryab 
Published: November 2018

Purpose
The purpose of this paper is to test the impact of symbolic and functional incongruity on brand hate. According to self-congruity theory, symbolic and functional congruence are a critical phenomenon in consumer buying decisions. Therefore, the present study develops a theoretical framework based on self-congruity theory to examine the key determinants of brand hate.

Design/methodology/approach
Data were collected only in fast-food chain franchises in the capital city territory of Pakistan. Therefore, it is hard to generalize the findings of this research for customers from different cultural backgrounds.

Findings
The results of the study reveal that symbolic and functional incongruence are the primary factors responsible for brand hate among Pakistani fast-food customers. Customers carefully consider both self-image and product attributes when purchasing products.

Research limitations/implications
The research uses the cross-sectional method, which limits the findings’ usefulness in other sectors.

Practical implications
The current research helps policymakers understand the key determinants of brand hate, showing that symbolic incongruence is the primary antecedent. Therefore, policymakers and corporate leaders should consider that Pakistan is an Islamic country where consumer choices of food are not only derived from food quality, food hygiene and service quality, but also the symbolic image (i.e. halal food) is a vital determinant of consumption.

Originality/value
This study contributes to the literature by discussing the above issue and presenting quantitative data. This research extends the literature by testing and validating a conceptual model that includes two types of congruence (symbolic and functional) to study brand hate. The proposed conceptual model provides a novel, theoretical, self-congruity point of view on brand hate.
Photograph as an act: toward information visual education
Authors: Santos Pérez Ana Cristina , Luna Gerardo Belmont 
Published: November 2018

Purpose
This paper is based on the analysis of a few photographs published by El Heraldo de México in 1968 about the student movement. The purpose of this paper is to consider the photograph as an act in which the observer is included. From this point of view, the observer could identify a discursive line of the newspaper and build an independent interpretation. The librarian is an observer.

Design/methodology/approach
It is a theoretical description about the objective character of the photographs published by El Heraldo de México in 1968. Considering photography as an act, this paper proposes to empirically identify the whole context of three cases of photographs of the newspaper, as examples.

Findings
Based on the contextualized interpretation (or photograph as an act), the photograph is identified as an information object and, therefore, an epistemological object, too. There is a relation between the image and the building of knowledge, through the interpretation of the observer.

Research limitations/implications
There are many studies about cataloguing and classification of images, but there is no study on the theoretical implications. The theory presented in this document comes from the work of other specialists and from other disciplines.

Practical implications
Learning to read visual information is as necessary as reading texts. The visual world waits to be decoded. And the twenty-first-century librarian knows how to organize, preserve and disseminate documentary collections (as photos). Value is how to find, access, decode and build knowledge over them.

Originality/value
In this document, the authors take a position in the library discussion about the image as an information object. Also, this paper promotes development of theoretical studies about this topic by librarians.
Rapid needs assessment: an evidence-based model
Authors: Lee Jin 
Published: November 2018

PurposeAlthough conducting a needs assessment has been accepted as the first step in solving performance problems, many human resource development (HRD) and training professionals find it still difficult to conduct an effective and efficient needs assessment. The primary reasons are the lack of a guiding model based on empirical evidence and the pressing need for a cost-effective approach. To resolve these issues, this paper aims to explore ways to conduct a needs assessment and propose an evidence-based needs assessment model.Design/methodology/approachFollowed the guidelines provided by Richey and Klein (2007), a design and development research was conducted. From the in-depth interviews with participants, the author proposed a more rapid model of needs assessment.FindingsThe salient features of the rapid needs assessment model are utilizing hypothetical interventions at an earlier stage in the process and gaining a commitment from the client across the entire process. Due to the exploratory nature of the present study, the rapid needs assessment model calls for further investigation in terms of strengths and weaknesses, and validation through multiple-case studies.Originality/valueThree significant features of the rapid needs assessment model are different from the existing needs assessment models: developing initial hypothetical interventions, engaging in an interactive and cyclical process and including the client in the whole process. The proposed model can also be used to guide HRD professionals which lays out the process and activities of needs assessment especially when the project due date is imminent, when performance problems should be addressed quickly or when the client requires results or at least the blueprint at an earlier phase.
Work-family conflict and female employees’ turnover intentions
Authors: Rasheed Mamoona , Iqbal Salman , Mustafa Faisal 
Published: November 2018

PurposeThe purpose of this study is to examine the influences of informal organisational and family support on work-family conflict (WFC) and its subsequent impact on turnover intentions among female employees.Design/methodology/approachTo evaluate the WFC among female individuals, data were collected through a questionnaire distributed among female employees in the service sector in Lahore, Pakistan, by using convenience-sampling technique. The collected data were analysed through a well-known statistical technique, SEM, using AMOS software.FindingsThe findings suggest that supports (informal organizational and family) have no impact to resolving the issues of WFC arising because of female members of the family working. Also, it was found that WFC is positively linked to employee turnover intentions.Practical implicationsBy addressing WFC issues, this research has key implication for WFC practically. This study has essential implications for organization, so it can reduce the WFC by creating a supportive environment to create balance amongst work and family life. Specifically, managers need to be aware of the impact that social support and WFC have on turnover intention.Originality/valueThis study provides the model of WFC that helps in future research. The research also improves past studies’ methodology by testing the direct and mediation impacts between the constructs specifically in female employees. This study is a valuable addition to the existing body of literature.
The validity of health belief model variables in predicting behavioral change
Authors: Sulat Jaelan Sumo , Prabandari Yayi Suryo , Sanusi Rossi , Hapsari Elsi Dwi , Santoso Budiono 
Published: November 2018

Purpose
The health belief model (HBM) is the behavioral change theory most widely used in health behavior studies. Several studies have identified the limitations of this model, one of which concerns the validity in predicting behavioral changes. The purpose of this paper, scoping review, is to map the validity of HBM variables in predicting behavioral changes based on available synthesized evidences.

Design/methodology/approach
A scoping review was conducted using the Arksey and O’Malley’s framework. PubMed, Health Evidence, Cochrane Database of Systematic Reviews, ScienceDirect and Google Scholar were searched using a combination of keywords: health belief model, review, systematic review and meta-analysis between February 15 and March 18, 2016.

Findings
Of the 1,457 articles, 4 met the inclusion criteria. All results showed that HBM variables were consistently related to behaviors and the strength of the correlation were varied. Perceived barriers and perceived benefits were the strongest predictor, while perceived severity was the weakest. The association between HBM variables and behaviors was moderated by some aspects of behavioral outcomes, the study design and the time interval between measurement of the HBM variables and behavior.

Originality/value
Although the four main variables of HBM have been shown to be related to behavior, the overall outcomes are varied and have not demonstrated conclusive evidence during the last ten years. The results of this scoping review imply the need for a systematic review and meta-analysis of the results of recent studies. In addition, more longitudinal studies are needed to ensure the validity of HBM variables by considering any possible moderators.
The moderating role of cultural factors in the adoption of mobile banking in Brazil
Authors: Goularte Alexandre da C. , Zilber Silvia Novaes 
Published: November 2018

Purpose
This study aims to evaluate the impact of country culture, represented by Hofstede cultural dimensions, in the adoption of Brazilian mobile banking services.

Design/methodology/approach
Based on the replication of a theoretical model previously tested in Mozambique (Africa) that combines the extended version of the unified theory of acceptance and use of technology (UTAUT2) with the five Hofstede cultural dimensions, this study tested that model in another emerging country, Brazil, using partial least squares (PLS) as a modeling method.

Findings
Replication showed that the cultural dimensions do not present strong significance in the moderation of the use of mobile banking. In fact, out of the five dimensions tested, three were not significant and two showed weak significance (p < 0.10): collectivism and short-term orientation. Those results, contrasting with that one presented by Baptista and Oliveira (2015), made sense under Ajzen’s theory (1991) – the TPB, leading to the conclusion that the moderation of cultural dimensions on behavior use is not applicable.

Originality/value
The authors concluded that the tested model may not be adherent, finding a theoretical gap to be explored in future studies: the moderation of the behavioral intention by cultural variables proposed by Hofstede. That finding supported the proposition of a new theoretical model, which considers the moderation of cultural dimensions in another place: behavioral intention to use mobile banking instead of the behavior use, as proposed by Baptista and Oliveira (2015). So, based on the research results and based on some authors cited in this study (Choi et al., 2014; Chou, 2013; Srite and Karahanna, 2006), it is proposed to insert Hofstede cultural variables as moderators of independent variables on the behavioral intention.
Investigating the benefits of online peer mentoring for student confidence and motivation
Authors: Fayram Jo , Boswood Nel , Kan Qian , Motzo Anna , Proudfoot Anna 
Published: November 2018

Purpose
The purpose of this paper is to report the findings of an online peer-mentoring initiative for language students at the Open University, UK. The communities of practice (CoP) model (Wenger, 2010) was used as a theoretical framework within which to explore the nature and extent of mentor and mentee participation; and the impact of the scheme on student confidence and motivation.

Design/methodology/approach
Within a qualitative paradigm, multi-data sources were employed to collect and analyse data. Participation was measured from analysis of online interaction, while participant views were captured through interviews, forum posts and surveys.

Findings
Findings revealed that mentors were perceived by students who used the scheme to be instrumental in building confidence and motivation. In addition, varying participation patterns indicated that students used the online learning communities to meet their differing needs during their studies. These needs involved passively reading posts as well as actively posting.

Research limitations/implications
Any direct statistical correlation between student confidence and motivation and online peer mentoring was beyond the scope of this study and could be the focus of future research. Additionally, research might also explore the impact of student mentors on student participation in wider CoPs.

Practical implications
Practical recommendations from the study include the importance of mentor training to develop effective communication strategies and to differentiate the role from that of tutor moderators, whose remit is to respond to academic content-related queries in module-wide forums.

Originality/value
There is little research into the nature and impact of online peer mentoring on student motivation and confidence. This study aimed to bridge this gap.
Search, sense making and learning: closing gaps
Authors: Marchionini Gary 
Published: November 2018

PurposeThis paper aims to discuss how search, sense making and learning have become more closely integrated, as search services have leveraged new technologies and large and media-diverse data streams.Design/methodology/approachThe paper reviews progress in search over the past 60 years, summarizes different theories of sense making and learning and proposes a framework for integrating these activities.FindingsThe arguments are supported with examples from search in 2018 and suggest that even as search becomes an automated process during learning, search strategies must continue to evolve to insure that complex information needs can be met.Research limitations/implicationsThe work is limited to search that uses electronic search systems. Implications include the need to understand that multiple levels of system inferences/estimates are used to present search results and that different kinds of learning processes are affected by search systems.Social implicationsThe importance of information literacy is implied.Originality/valueThis paper will provide readers with an understanding of how search services and systems have evolved and their implications for human learning.
Television advertising’s influence on parents’ gift-giving perceptions
Authors: Holiday Steven , Norman Mary S. , Cummins R. Glenn , Hernandez Terri N. , Holland Derrick , Rasmussen Eric E. 
Published: November 2018

Purpose
This study aims to examine factors, beyond child requests, that influence parents’ perceptions of the most important gifts to give their children by assessing the influence of television advertising on children’s programming.

Design/methodology/approach
Using agenda-setting as a theoretical and methodological template, a content analysis of 7,860 commercials in children’s programming was compared using a questionnaire to 143 parents of 240 children to test the transfer of salience between advertising and parents’ perceptions. The study also examined the role of child purchase requests in this relationship.

Findings
The product categories that most prevalently advertised on children’s television had a significant relationship with the product categories that parents perceived to be the most important to give their children as gifts. Furthermore, the results indicate that this relationship was not contingent upon parental advertising mediation or child product requests.

Research limitations/implications
The results are limited to a single broadcast market during the Christmas season. Strategically, the research suggests that advertising through children’s television programming may be an effective way to directly inform parents’ gift-giving consideration sets, and this target and outlet should be strategically evaluated in subsequent campaign decisions about the marketing mix.

Originality/value
The findings add new insights to the gift-giving literature, indicating that advertising in children’s programming may be an alternative direct influence on parents’ perceptions. This research also extends research on advertising agenda setting into the new context of commercial advertising of consumer products.
Developing a consumer relationship model of corporate social performance
Authors: Eveland Vicki Blakney , Crutchfield Tammy Neal , Rynarzewska Ania Izabela 
Published: November 2018

PurposeThis paper aims to address the complex nature of social performance (CSP/CSR) in building a trust-based consumer relationship. The relative and aggregate influence of corporate functional performance, corporate social performance (CSP) and shared values within a trust-based customer–brand relationship and their impact on behavioral loyalty in the forms of retention, referral and ease of voice are empirically tested.Design/methodology/approachRespondents were recruited to participate in a study on ice cream shop preferences. Structural equation modeling was used to simultaneously test the effects of independent variables on dependent variables.FindingsShared values mediate the effect that CSP has on trust and all loyalty behaviors. Trust has a significant influence on one behavior:retention.Research limitations/implicationsThe findings may be specific by industry, product type or consumer involvement. Further tests should be performed with varying levels of each.Practical implicationsMillennial consumers expect organizations/brands to engage in CSR activities, and, because of increased CSP reporting, are aware of an organization’s CSR efforts. If the CSP does not reflect the customer’s value system (shared values), the long-term relationship can be impacted negatively. Firms must strategically consider the values communicated by their CSR activities to build and care for long-term relationships with their target consumer.Originality/valueThis research is the first to integrate and test a comprehensive consumer relationship model of CSP.
Family factors and fruit and vegetable consumption in Chinese preschool children living in Hong Kong
Authors: Chan Ruth , Yeung Suey , Leung Cynthia , Lo Sing Kai , Tsang Sandra 
Published: November 2018

PurposeThe purpose of this paper is to examine the association of various family factors with children’s fruit and vegetable (FV) intake.Design/methodology/approachA cross-sectional analysis of data from 601 parent-child dyads with children aged three to six years old was conducted. Parents completed questionnaires on child’s FV intake, parenting styles, parental feeding practices, family functioning, television viewing at mealtimes and frequency of family meals. Logistic regression was used to assess the association between various family factors and the likelihood of meeting the child’s daily FV recommendation with adjustment for different demographic variables.FindingsMultivariate model adjusting for sociodemographic data indicated that meeting vegetable recommendation was associated with lower frequency of dining with grandparents (Odds ratio (OR) 0.94, 95% confidence interval (CI) 0.89–0.99,p=0.031) and positively associated with parents using more desirable parental feeding practices (OR 1.15, 95% CI 1.09–1.21,p<0.001). Meeting fruit recommendation was associated with parents using more desirable parental feeding practices (OR 1.13, 95% CI 1.09–1.17,p<0.001), higher frequency of dining with grandparents (OR 1.05, 95% CI 1.00–1.10,p=0.041), lower frequency of dining with father (OR 0.89, 95% CI 0.82–0.98,p=0.014) and higher score on authoritative parenting style (OR 1.05, 95% CI 1.01–1.08,p=0.009).Originality/valueThis study highlights the potential protective roles of various family factors, in particular authoritative parenting style and parental feeding practices, such as role modeling, moderate restrictive practices for less healthy foods, avoidance of forced feeding, and not using junk food as reward in relation to meeting FV recommendation in children. The role of grandparents in influencing the young children’s eating behaviors within the Chinese family warrants further investigation.
