Ethical dilemmas in education: a case study of challenges faced by secondary school leaders in Kenya
Authors: Oduol Truphena , Cornforth Sue 
Published: May 2019

Purpose
The purpose of this paper is to question the usefulness of Euro-Western concepts of principled ethical behaviour for school leaders in non-Euro-Western countries by examining the dilemmas faced by Kenyan educational leaders.

Design/methodology/approach
A single, multi-site case study methodological approach was used, and data gathered by means of semi-structured interviews with stakeholders: school principals, boards of governors, heads of department, school bursars and parents.

Findings
Findings highlighted the importance of contextual variables in influencing leaders’ decisions, indicative of the tension between liberal and communitarian ethical approaches. Although similar dilemmas were encountered to those working in euro-western contexts, Kenyan educational leaders faced the additional challenge of working with cultural values of Ubuntu: care for the whole community, harmonious working relationships, loyalty to one’s kin and respect of seniority. Furthermore, the problems they encountered were often life-threatening resulting from poverty, and HIV/Aids.

Originality/value
This paper contributes to the literature on ethics in educational leadership by proposing that the adoption of euro-western ethical standards and perspectives in non-Euro-Western countries is problematic, unless mitigated by a dialogic approach.
Technological proximity and the intensity of collaboration along the innovation funnel: direct and joint effects on innovative performance
Authors: Anzola-Román Paula , Bayona-Sáez Cristina , García-Marco Teresa , Lazzarotti Valentina 
Published: May 2019

PurposeThis paper aims to advance the understanding regarding the profiting of collaborative innovation practices, focusing particularly on how the intensity of collaboration along the innovation process and the relatedness between the partners’ technological bases affect the outcomes of such process in terms of efficiency and generation of technological innovations.Design/methodology/approachDrawing on the results from causal models and the estimation of average marginal effects, this research analyses the direct and joint effect of technological proximity and intensity of collaboration in the early and late phases of the process.FindingsThe findings suggest that there is a positive unconditional relationship between the aforementioned aspects and innovative performance and that the joint effects diverge depending on the stage of the process, i.e. while in the early phase collaborating intensely with close partners seems to be advisable, this circumstance proves to be problematic in the late phase of the innovation process.Originality/valueThe analysis developed provides clarity regarding relevant aspects of collaborative innovation practices, particularly, the search for and selection of optimal partners. In general terms, the evidence found here suggests seeking for collaborating intensely along the whole process with partners whose technological bases present a tight matchup with that of the focal firm. Results also call for awareness of the potential drawbacks derived from intense collaborations with close partners in the late phases of the process, thus hinting toward the convenience of developing protection mechanisms. In addition, this work provides interesting insights that challenge the notion of “proximity paradox” and set out further questions that might be worth considering for future research.
Relationship between social media activities and thinking styles
Authors: Xu Huan , Gong Yanping , Zhang Qin , Xie Julan 
Published: May 2019

PurposeThe purpose of this paper is to gain more insight into the relationship between social media activities and thinking styles, and its potential mechanism.Design/methodology/approachThe current study conducted four studies using an experimental method and eye-tracking method to evaluate prediction.FindingsResults from studies 1 and 2 showed that social media activities influence individuals’ self-construal, and the impact of self-construal on the relative reliance on cognitive vs affective thinking styles. Study 3 supports the hypothesis that social media activities influence individual’s thinking styles, and self-construal is a critical mediator in this process. Furthermore, the authors replicated these findings using an experimental method and eye-tracking method (Study 4), which enabled us to better understand the consumer’s psychological experience when using social media.Originality/valueThis paper contributes to the social media activity literature in the following ways. First, this research advances the knowledge of social media by demonstrating that social media activities can have significant effects on thinking styles. Second, the current research brings important insights to the literature on self-construal. Finally, using eye-tracking methods, the authors also provided some new insights on consumer thinking and behavior.
Brand entification as a post-anthropomorphic attribution among Twitter-using Millennials
Authors: Sashittal Hemant , Jassawalla Avan 
Published: May 2019

Purpose
The purpose of this paper is to report a three-study effort that aimed to explicate the brand entification construct, a post-anthropomorphic attribution that results from user-brand interaction on Twitter. Entified brands are not merely humanlike, they are viewed as human celebrities with an elevated social status.

Design/methodology/approach
A testable conceptual framework, hypotheses and measurement scales for explicating the brand entification construct are derived from focus groups. The framework is tested using two separate surveys; the first surveyed college going, Millennial users of Twitter, the second surveyed a nationwide sample of Twitter using Millennials.

Findings
The fear of being ignored (FOBI) emerges as the key antecedent of brand entification. Elevation in healthy narcissism emerges as its key consequence. Twitter users experiencing elevated narcissism are found to defend entified brands when they receive negative tweets from other users.

Research limitations/implications
All constructs and measurement scales reported in the data are new, the evidence of linkages between the antecedents and consequences of brand entification are similarly unprecedented; both reflect the theoretical contributions of the study. Further testing of scales, and replication of results using multiple samples of Twitter users are essential before formalized theory and widely generalizable findings emerge.

Practical implications
Shaping Twitter-users’ sense of healthy narcissism emerges as the key challenge for managers aiming to build brands via Twitter communication. Stimulating users’ FOBI emerges as a key entry-way in this process.

Originality/value
The paper reports the first empirical investigation of the brand entification construct in the context of Twitter-using Millennials.
Governing day-to-day interactions in the execution phase of an interfirm collaboration
Authors: Grunwald-Delitz Stefan , Strauss Erik , Weber Juergen 
Published: May 2019

PurposeThis paper aims to advance understanding of the role of informal controls for governing day-to-day interactions in the execution phase of interfirm collaborations. It explores the nature of these informal controls and how they are used by the firm’s partners during this phase.Design/methodology/approachIn-depth case study of a lateral relationship between a car manufacturer and its suppliers, based on interviews, observations and archival material, and using concepts from the field of psychology.FindingsThe results reveal an interfirm collaboration in which the supplier, in particular, relies on so-called informal interpersonal controls for micro-contracting and solving the control problems of its day-to-day interactions. Specifically, the study finds that the collaboration partners rely on interpersonal influence tactics for influencing behavior, coordinating the activities of the collaboration partners, and mitigating collaborative risks. Depending on the specific individual, in terms of, for example, their “mood”, and the contingencies of the explicit interaction, such as contradicting flanking contractual agreements, the actors engage in different activities, including ingratiation, pressure or rational persuasion.Originality/valueThis study illuminates the role of informal controls in interfirm settings by distinguishing analytically between interpersonal and interorganizational informal controls. By mobilizing the psychological concepts of interpersonal influence tactics, the extant research in this field is complemented through the illustration of how the actors use informal control mechanisms, depending on their corresponding counterpart, and the specific situation of the interaction. The findings thereby highlight the situated nature of governance, suggesting that governance between collaboration partners is not a static condition, rather an ongoing process in which the actors use, and alternate between, distinct tactics in their daily interactions.
Cool perspectives, Indian cool and branding
Authors: Duggal Ekta , Verma Harsh V. 
Published: May 2019

Purpose
Cool has been studied mostly in consumer samples drawn from Western countries. This study was inspired by paucity of literature on “cool” in an Indian context. There is certainty that “cool” adds value and bestows desirability but there is uncertainty about what “cool” means. Since “cool” is a cultural phenomenon, the purpose of this paper is to explore its meaning in the Indian context.

Design/methodology/approach
The data were obtained on an open-ended questionnaire followed by depth probes on a sample of young consumers. The obtained scripts were coded and classified into semantic categories based on the grounded theory.

Findings
The study found that cool is indicated by seven facets, including being oneself, living life to the fullest, sense of humor and socially networked, and calm disposition. Unlike Western notions, in India, cool is not being deviant and hedonistic. The cultural and religious imprints are palpable in what is construed as cool in India.

Research limitations/implications
Transplanting the Western notions of cool for brand building is likely to be a risky proposition. It may not resonate with the inner cords of the Indian youth. The implication of this study is that it reveals possible ways in which cool can be incorporated in brand identity.

Practical implications
Cool is valued because it bestows distinction in subtle ways. Brands can gain traction among consumers by incorporating cool symbolism in their identity.

Originality/value
This study expands the understanding of cool in the context of an emerging market. This is one of the first studies to have probed the concept of “cool” in India.
Library in 3D virtual world: a critical review
Authors: De Sarkar Tanmay 
Published: May 2019

Purpose
The purpose of the present study is to explore the possibility of introducing a 3D environment in the library by reviewing current literature and to provide a good understanding of different purposes of using this immersive environment.

Design/methodology/approach
The present paper is a narrative account of libraries’ presence in the virtual world in combination with an overview of how libraries respond to the 3D environment. Relevant data for the review paper have been collected from library websites, books, journal articles, interview, etc.

Findings
The study found purposive involvement of libraries in this immersive environment which indicates that users use this exciting 3D medium to satisfy their information requirement.

Research limitations/implications
The paper basically considers publications containing observations of broader research community in the relevant field and contents in websites dealing with virtual world and outlines the major features as discussed in available documents. The review study infers that the implementation of 3D project in libraries requires a mindset for the specific approach, from the end of both librarians and users, together with involvement of funds. Therefore, a library may start with a beta project and observe the effectiveness from the users’ perspective before embarking on a full-fledged project.

Originality/value
With numerous examples, as evident from publications and websites, the current review study makes an attempt to improve the understanding of librarians towards informed selection of projected purposes to be integrated with the virtual world from library perspective. The study also presents different approaches of libraries motivating users in the virtual world that other libraries may follow while considering their 3D library project.
Propagation of seismic waves in patchy‐saturated porous media: double‐porosity representation
Authors: Sharma M.D. 
Published: May 2019

ABSTRACTPropagation of harmonic plane waves is studied in a patchy‐saturated porous medium. Patchy distribution of the two immiscible fluids is considered in a porous frame with uniform skeletal properties. A composition of two types of patches, connected through continuous paths, constitutes a double‐porosity medium. Different compressibilities of pore‐fluids in two porous phases facilitate the wave‐induced fluid‐flow in this composite material. Constitutive relations are considered with frequency‐dependent complex elastic coefficients, which define the dissipative behaviour of porous aggregate due to the flow of viscous fluid in connected patches. Relevant equations of motion are solved to explain the propagation of three compressional waves and one shear wave in patchy‐saturated porous solids. A numerical example is solved to illustrate dispersion in phase velocity and quality factor of attenuated waves in patchy‐saturated porous materials. Role of fluid–solid inertial coupling in Darcy's law is emphasized to keep a check on the dispersion of wave velocities in the porous composite. Effects of patchy saturation on phase velocities and quality factors of attenuation are analysed using the double‐porosity formulation as well as the reduced single‐porosity equivalents.
Race, power and intimacy in the intersubjective field: the intersection of racialised cultural complexes and personal complexes
Authors: Calland Ruth 
Published: May 2019

AbstractThis paper presents work with a biracial young woman, in the context of a predominantly white Jungian training organisation. The patient's relational difficulties and her struggle to integrate different aspects of her personality are understood in terms of the overlapping influences of developmental trauma, transgenerational trauma relating to the legacy of slavery in the Caribbean, conflictual racial identities, internalised racism, and the British black/white racial cultural complex. The author presents her understanding of an unfolding dynamic in the analytic relationship in which the black slave/white master schema was apparently reversed between them, with the white analyst becoming subservient to the black patient. The paper tracks the process through which trust was built alongside the development of this joint defence against intimacy ‐ which eventually had to be relinquished by both partners in the dyad. A white on black ‘rescue fantasy’, identified by the patient as a self‐serving part of her father's personality, is explored in relation to the analytic relationship and the training context.
Active Dry Yeast: Lessons from Patents and Science
Authors: Gélinas Pierre 
Published: May 2019

AbstractIn the production of fermented foods, long‐term preservation of the activity of microbial starters is a critical issue. The aim of this review was to determine key challenges in the production and use of active dry yeast over time and to compare statistics on letters patent for inventions and applied scientific articles as indicators of technological evolution. The review covers 280 original patent specifications and 212 applied scientific articles issued between 1796 and 2018, not including documents in basic science or without obvious application in fermented foods. The main subject matter was baking and the other entries applied to wine and, to a lesser extent, beer and spirits. Very popular in patents granted in the 19th century until about 1935 but ignored in the scientific literature, dehydrated yeast preparations often consisted of wet biomass concentrates mixed with large amounts of water‐absorbing agents. Long‐term survival of dehydrated yeast cells progressively improved with specific strains, growth conditions, and, to a lesser extent, drying conditions. Since the 1990s, both inventors and scientists have mainly targeted yeast cells protection during rehydration, a most critical factor. Proper review of the scientific literature would be incomplete unless it includes patents, a much ignored but relevant source of information.

ObjectiveCancer recurrence is a complicated problem for clinicians that contributes to poor prognosis. This study aimed to use advanced gastric carcinoma genes profiles to predict increased risk of cancer recurrence in order to identify patients in need of adjuvant therapy for prognosis improvement.MethodsDifferentially expressed genes were identified for advanced gastric carcinoma by analyzing the GSE2685 from the Gene Expression Omnibus database (GEO) using R package. The candidate genes were then obtained by gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, protein‐protein interaction analysis and survival analysis. Logistic regression analysis was performed to determine the relationship between candidate genes and the recurrence of gastric carcinoma.ResultsCollagen type IV alpha 1 (COL4A1) was overexpressed in gastric carcinoma tissue by analyzing the GSE2685 gene expression profiles from the Gene Expression Omnibus database. COL4A1 was also overexpressed in gastric carcinoma tissue from the Cancer Genome Atlas dataset and further determined that higher COL4A1 expression led to poorer overall survival. A univariate analysis suggested that COL4A1 was strongly correlated with T stage and gastric carcinoma recurrence (P = 0.014 and 0.041, respectively). Moreover, a multiple logistic regression analysis indicated that COL4A1 was significantly associated with gastric carcinoma recurrence (hazard ratio 1.605, 95% confidence interval 1.063‐2.677, P = 0.008).Conclusions
COL4A1 may promote gastric carcinoma recurrence and could be used as a therapeutic target for gastric carcinoma recurrence.
Trimitomics: An efficient pipeline for mitochondrial assembly from transcriptomic reads in nonmodel species

Published: May 2019

AbstractMitochondrial resources are of known utility to many fields of phylogenetic, population and molecular biology. Their combination of faster and slower‐evolving regions and high copy number enables them to be used in many situations where other loci are unsuitable, with degraded samples and after recent speciation events.The advent of next‐generation sequencing technologies (and notably the Illumina platform) has led to an explosion in the number of samples that can be studied at transcriptomic level, at relatively low cost. Here we describe a robust pipeline for the recovery of mitochondrial genomes from these RNA‐sequencing resources. This pipeline can be used on sequencing of a variety of depths, and reliably recovers the protein coding and ribosomal gene complements of mitochondria from almost any transcriptomic sequencing experiment. The complete sequence of the mitochondrial genome can also be recovered when sequencing is performed in sufficient depth. We show the efficacy of our pipeline using data from eight nonmodel invertebrates of six disparate phyla. Interestingly, among our poriferan data, where microbiological symbionts are known empirically to make mitochondrial assembly difficult, this pipeline proved especially useful. Our pipeline will allow the recovery of mitochondrial data from a variety of previously sequenced samples, and add an additional angle of enquiry to future RNA‐sequencing efforts, simplifying the process of mitochondrial genome assembly for even the most recalcitrant clades and adding these data to the scientific record for a range of future uses.
Has Adoption of IFRS Increased Non–North American Institutional Investment in the Canadian Stock Markets?
Authors: Khan Shahid , Anderson Mark , Warsame Hussein , Wright Michael 
Published: May 2019

AbstractWe investigate whether non–North American (non‐NA) institutional investment in firms listed on the Canadian stock markets increased between the pre‐ and post‐IFRS adoption periods relative to such investment in firms listed on the U.S. stock markets. Prior to IFRS adoption, Canada had high‐quality financial reporting standards that were similar to the U.S. standards. As consequences of IFRS adoption, Canadian financial statements became more comparable with European and other IFRS country financial statements and less comparable with neighboring U.S. financial statements. Thus, a question of interest is whether the enhanced comparability with non‐NA companies was beneficial in terms of attracting non‐NA investment to Canadian companies versus U.S. companies. We find that there was no significant change in non‐NA institutional investment in Canadian firms relative to U.S. firms for the very largest (fifth quintile) and for smaller (first, second, and third quintiles) Canadian companies. However, intermediate‐sized Canadian companies in the fourth size quintile lost non‐NA institutional investment relative to their U.S. peer companies, suggesting that non‐NA investors cared more about comparability with U.S. peer companies than non‐NA peer companies for companies in this size quintile.
Preliminary Evidence That Real World Sleep Timing and Duration are Associated With Laboratory‐Assessed Alcohol Response
Authors: Hasler Brant P. , Wallace Meredith L. , White Sarah J. , Molina Brooke S. G. , Pedersen Sarah L. 
Published: May 2019

BackgroundSleep timing and evening chronotype have been implicated in alcohol use problems but research has yet to study them in relation to theory‐driven laboratory‐based measures of alcohol use disorder risk. The current study examined (i) whether chronotype, sleep timing, and/or sleep duration are associated with alcohol response (subjective stimulation, sedation, and behavioral disinhibition) and (ii) if sex and race moderate these associations.MethodsAdult drinkers (N = 144; 46 female participants) completed 2 counterbalanced beverage administration sessions (alcohol and nonalcohol) during which they rated stimulation/sedation and completed a cued go/no‐go task. They reported bed and waketimes over 10 days.ResultsLater sleep timing was associated with greater increases in alcohol stimulation, but among male and White participants only. Later sleep timing (among male participants) and greater eveningness (examined among White male participants only) were associated with greater overall stimulation on average in the alcohol session relative to the nonalcohol session, irrespective of alcohol consumption. More variable sleep duration was associated with greater increases in sedation.ConclusionsThese findings offer preliminary, but novel evidence that sleep characteristics may relate to the relative stimulating and sedating effects of alcohol, thereby influencing the risk for alcohol problems.
