Published: March 2020

AbstractHearing loss is associated with changes at the peripheral, subcortical, and cortical auditory stages. Research often focuses on these stages in isolation, but peripheral damage has cascading effects on central processing, and different stages are interconnected through extensive feedforward and feedback projections. Accordingly, assessment of the entire auditory system is needed to understand auditory pathology. Using a novel stimulus paired with electroencephalography in young, normal-hearing adults, we assess neural function at multiple stages of the auditory pathway simultaneously. We employ click trains that repeatedly accelerate then decelerate (3.5 Hz frequency modulation; FM) introducing varying inter-click-intervals (4 to 40 ms). We measured the amplitude of cortical potentials, and the latencies and amplitudes of Waves III and V of the auditory brainstem response (ABR), to clicks as a function of preceding inter-click-interval. This allowed us to assess cortical processing of frequency modulation, as well as adaptation and neural recovery time in subcortical structures (probably cochlear nuclei and inferior colliculi). Subcortical adaptation to inter-click intervals was reflected in longer latencies. Cortical responses to the 3.5 Hz FM included phase-locking, probably originating from auditory cortex, and sustained activity likely originating from higher-level cortices. We did not observe any correlations between subcortical and cortical responses. By recording neural responses from different stages of the auditory system simultaneously, we can study functional relationships among levels of the auditory system, which may provide a new and helpful window on hearing and hearing impairment.

ABSTRACTSince all forms of mimicry are based on perceptual deception, the sensory ecology of the intended receiver is of paramount importance to test the necessary precondition for mimicry to occur, i.e. model-mimic misidentification, and to gain insight in the origin and evolutionary trajectory of the signals. Here we test the potential for aggressive mimicry by a group of coral reef fishes, the color polymorphicHypoplectrushamlets, from the point of view of their most common prey, small epibenthic gobies and mysid shrimp. We build visual models based on the visual pigments and spatial resolution of the prey, the underwater light spectrum and color reflectances of putative models and their hamlet mimics. Our results are consistent with one mimic-model relationship between the butter hamletH. unicolorand its model the butterflyfishChaetodon capistratusbut do not support a second proposed mimic-model pair between the black hamletH. nigricansand the dusky damselfishStegastes adustus. We discuss our results in the context of color morphs divergence in theHypoplectrusspecies radiation and suggest that aggressive mimicry inH. unicolormight have originated in the context of protective (Batesian) mimicry by the hamlet from its fish predators.
The relation between intrinsic protein conformational changes and ligand binding
Authors: de Boer Marijn 
Published: March 2020

1ABSTRACTStructural changes in proteins allow them to exist in several conformations. Non-covalent interactions with ligands drive the structural changes, thereby allowing the protein to perform its biological function. Recent findings suggest that many proteins are always in an equilibrium of different conformations and that each of these conformations can be formed by both the ligand-free and ligand-bound protein. By using classical statistical mechanics, we derived the equilibrium probabilities of forming a conformation with and without ligand. We found, under certain conditions, that increasing the probability of forming a conformation by the ligand-free protein also increases the probability of forming the same conformation when the protein has a ligand bound. Further, we found that changes in the conformational equilibrium of the ligand-free protein can increase or decrease the affinity for the ligand.
The Persistence Potential of Mobile Genetic Elements
Authors: Wang Teng , You Lingchong 
Published: March 2020

AbstractMobile genetic elements (MGEs), such as plasmids, phages, and transposons, play a critical role in mediating the transfer and maintenance of diverse traits and functions in microbial communities. This role depends on the ability of MGEs to persist. For a community consisting of multiple populations transferring multiple MGEs, however, the conditions underlying the persistence of these MGEs are poorly understood. Computationally, this difficulty arises from the combinatorial explosion associated with describing the gene flow in a complex community using the conventional modeling framework. Here, we describe an MGE-centric framework that makes it computationally feasible to analyze such transfer dynamics. Using this framework, we derive the persistence potential: a general, heuristic metric that predicts the persistence and abundance of any MGEs. We validate the metric with engineered microbial consortia transferring mobilizable plasmids and quantitative data available in the literature. Our modeling framework and the resulting metric have implications for developing a quantitative understanding of natural microbial communities and guiding the engineering of microbial consortia.

AbstractCaloric restriction has been shown to decrease the incidence of metabolic diseases such as obesity and type 2 diabetes mellitus (T2DM). The mechanisms underlying the benefits of caloric restriction involved in insulin secretion and glucose homeostasis and are not fully understood. Intercellular communication within the islets of Langerhans, mediated by Connexin36 (Cx36) gap junctions, regulates insulin secretion dynamics and glucose homeostasis. The goal of this study was to determine if caloric restriction can protect against decreases in Cx36 gap junction coupling and altered islet function induced in models of obesity and prediabetes. C57BL6 mice were fed with a high fat diet (HFD), showing indications of prediabetes after 2 months, including weight gain, insulin resistance, and elevated fasting glucose and insulin levels. Subsequently, mice were submitted to one month of 40% caloric restriction (2g/day of HFD). Mice under 40% caloric restriction showed reversal in weight gain and recovered insulin sensitivity, fasting glucose and insulin levels. In islets of mice fed the HFD, caloric restriction protected against obesity-induced decreases in gap junction coupling and preserved glucose-stimulated calcium signaling, including Ca2+oscillation coordination and oscillation amplitude. Caloric restriction also promoted a slight increase in glucose metabolism, as measured by increased NAD(P)H autofluorescence, as well as recovering glucose-stimulated insulin secretion. We conclude that declines in Cx36 gap junction coupling that occur in obesity can be completely recovered by caloric restriction and obesity reversal, improving Ca2+dynamics and insulin secretion regulation. This suggests a critical role for caloric restriction in the context of obesity to prevent islet dysfunction.
Theoretical analysis of neural crest cell migration
Authors: Khataee Hamid , Czirok Andras , Neufeld Zoltan 
Published: March 2020

AbstractThe neural crest cells are embryonic stem cells that migrate throughout embryos and, at different target locations, give rise to the formation of a variety of tissues and organs. The directional migration of the neural crest cells is experimentally described using a process referred to as contact inhibition of locomotion (CIL), by which cells redirect their movement upon the cell–cell contacts. However, it is unclear how the migration alignment is affected by the motility properties of the cells. Here, we computationally model the migration alignment and the average time to reach a target location as functions of the motility dynamics and interaction of the cells in an open domain with a channel geometry. The results indicate that by varying the properties of the CIL interaction a transition takes place from random movement of the cells to an organized collective migration, where the migration alignment is maximised and the migration time is minimised. This phase transition is accelerated and strengthened with the influx rate of the cells into the domain through increasing the density of the migrating cells. The model further suggests that the migration is more coordinated when the cells with a large CIL radius move fast in a narrow domain.
Negative disclosures in corporate social responsibility reporting
Authors: Einwiller Sabine A. , Carroll Craig E. 
Published: March 2020

PurposeThis study aims to reveal the quantity, quality and cultural differences of negative corporate social performance (CSP) disclosures in large firms' corporate social responsibility (CSR) reports. Firms are expected to be transparent about the impacts and outcomes of their CSP. A central aspect of transparency is balance, which means disclosing both positive and negative CSP.Design/methodology/approachContent analysis was applied to 75 CSR reports of large firms chosen from the Forbes Top 500 list. The firms belong to three cultural clusters: Anglo, Confucian Asia and Germanic/Nordic Europe.FindingsFirms made few negative CSP disclosures, yet the quantity of negative CSP disclosures varied among cultural clusters. Reports from Germanic/Nordic Europe showed the highest number of negative CSP disclosures, reports from Confucian Asia showed the lowest number and the Anglo cluster's number fell in between. The Asian firms communicated corrective actions more often than firms from the other clusters.Research limitations/implicationsThis study focused on negative CSP disclosures in the CSR reports – not omitting negative CSP. The practice of self-laudatory CSR communication decreases the likelihood that relevant stakeholders will believe what firms report about.Originality/valueStudies on the quality and quantity of negative disclosures are rare; by examining cultural differences, this study contributes to the limited body of knowledge.
“You really shouldn't have!” Coping with failed gift experiences
Authors: Branco-Illodo Ines , Heath Teresa , Tynan Caroline 
Published: March 2020

PurposeThis paper aims to examine coping approaches used by receivers to deal with failed gift experiences, thereby dealing with misperceptions between givers and receivers that could affect their relationship.Design/methodology/approachThis study uses a sequential, multimethod methodology using background questionnaires, online diary method and 27 semi-structured interviews.FindingsReceivers cope with failed gift experiences through concealing, disclosing or re-evaluating the gift experience. These approaches encompass several coping strategies, allowing receivers to deal with their experiences in ways that help them manage their relationships with givers.Research limitations/implicationsInformants described gift experiences in their own terms without being prompted to talk about coping, thus some insights of coping with failed gifts may have been missed. Multiple data collection methods were used to minimise this limitation, and the research findings suggest new avenues for future research.Practical implicationsThe present research helps retailers and brands to minimise gift failure by promoting gifts that emphasise aspects of the giver–receiver relationship, assists givers in their learning from gift failure by making them aware of the receiver’s preferences and reduces the cost of gift failure by offering further opportunities to dispose of unwanted gifts.Originality/valueThis paper contributes to the emerging topic of consumer coping by providing a novel and rounded understanding of coping in the context of failed gift events, identifying new reasons for gift failure, highlighting receivers’ ethical considerations when responding to failed gifts and proposing new insights for the coping literature.
Research in nonprofit human resource management from 2015 to 2018
Authors: Cooper Elizabeth A. , Phelps Aimee DuVall , Rogers Sean Edmund 
Published: March 2020

PurposeThis paper systematically reviews the past four years of research on human resource management (HRM) in nonprofit organizations (NPOs) to better understand: (1) recent theoretical and empirical developments and where scholarship in the field is headed (i.e. trends); (2) what topics and findings are especially important to understanding how the thought and practice of nonprofit HRM differs from that in public and for-profit organizations (i.e. insights); and (3) what gaps exist in current knowledge and scholarship and some real-world, practice-driven developments in people management that illuminate promising future research directions (i.e. opportunities).Design/methodology/approachSixty-seven peer-reviewed journal articles covering the period 2015–2018 were identified using a university library database search, as well as by-hand searches through every issue of 22 nonprofit and 36 human resources-related journals during the four-year period.FindingsThe findings highlight strong continued interest by scholars in a wide range of nonprofit HRM issues, coverage of these issues by a worldwide network of researchers who bring global perspectives and contexts to the study of nonprofit HRM, and rich theoretical and methodological diversity. Yet, compared with the universe of possible human resource topics and several leading-edge developments in organizations and societies that might affect the way people are managed in nonprofits, the paper uncovers gaps in the most recent knowledge base.Originality/valueThe paper creates a compilation of the most recent nonprofit human resource research to be used as a tool for scholars, students, and practitioners for many years to come.
Intention to adopt online learning
Authors: Watjatrakul Boonlert 
Published: March 2020

PurposePersonality traits and perceived value have been the focus for research in online learning adoption. However, there is a lack of understanding of how the effects of perceived value on online learning adoption vary according to the different personality traits and the levels of a personality trait. This study explores the moderating roles of the Big Five personality traits (i.e. neuroticism, extraversion, conscientiousness, openness to experience, and agreeableness) in the relationships between the perceived value (i.e. value for money, quality, emotional value, and social value) and intention to study online courses.Design/methodology/approachA survey questionnaire was used to collect data from university students. This study used the partial least squares structural equation modeling (PLS-SEM) method to measure the quality of the formative and reflective constructs and examine the moderating effects of the five personality traits in four models. The regression of intention to study online courses on the perceived value at the different levels of a personality trait was analyzed by the simple slope analysis approach.FindingsThe study found that particular personality traits moderate the relationships between the perceived value and intention to study online courses. Neuroticism and openness to experience have the moderating effects on the relationship between perceived value for money and intention to study online courses. Neuroticism is the only personality trait that moderates the effect of perceived emotional value on intention to study online courses. In addition, the different levels of a personality trait differentially moderate the effects of the perceived value on intention to study online courses.Originality/valueThis study is considered among the first research attempting to explore the moderating roles of the Big Five personality traits in the context of online learning adoption. It bridges the research gap in online learning literature and generalizes the impacts of perceived value on online learning adoption to the different personality traits and the levels of a personality trait. The results provide guidance for educational institutions to develop an effective online learning strategy by creating and communicating the right value propositions to the right group of students based on their personality traits.
On dialectics in theorizing: the contingent nature of organizational learning
Authors: Meisinger Norman 
Published: March 2020

PurposeDuring the past decades, numerous contributions to organizational learning have emerged. However, these theories are plagued by the same paradoxical core that prevents organizational learning from being unambiguously determined or stably located throughout the entire organization and its individuals. The purpose of this paper is to understand how researchers approach this issue.Design/methodology/approachThrough a meta-lens, this conceptual study observes how researchers are taming the paradox of organizational learning, referring exclusively to the theories that deal with its inherent paradox.FindingsThe author distinguishes fundamentally different theorizing strategies. Therefore, the paper aims not to sharpen the elusive and fuzzy nature of organizational learning but to sharpen the elusive understanding that its nature is fuzzy. As a consequence, the study further emphasizes how challenging an instrumental use of the academic construct of organizational learning for practicing managers outside research laboratories is.Originality/valueThe paper contributes (first) to the core understanding of the inherently conflicting construct of organizational learning by (second) uncovering the dialectics of the theories concerning it – the former only becomes feasible as a result of the latter.

Authors: Mahajan Ritika 
Published: March 2020

Purpose
The purpose of this paper is to explore perspectives of academicians in leadership positions in Indian business schools on the sustainability of management education institutions in India.

Design/methodology/approach
Semi-structured interviews were conducted with 20 respondents including directors, deans and vice-chancellors of private and public sector institutions offering management programmes across India. The interviews were audio recorded and transcribed verbatim for analysis.

Findings
All the respondents strongly supported the need for building sustainable management education institutions. Different factors affecting sustainability of institutions that emerged from the interviews included focus on local context and inter-disciplinarity, visionary leadership and culture, country specific curriculum and pedagogy, sustained industry-academia collaboration, faculty orientation, training, retention and growth. On the basis of the factors identified, a directional proposition with the perspective of blue ocean strategy is proposed.

Originality/value
There is a vast scope for exploring issues, challenges and strategies for building sustainable management education institutions. Literature in this field in the Indian context is very limited. This paper is one of the few attempts to study perspectives and experiences of leaders in Indian business schools on the sustainability of their institutions.
Experimental study on leakage and wear characteristics of C/C composite finger seal
Authors: Lu Fei , Liu Jian , Lu Hongyan 
Published: March 2020

Purpose
The carbon/carbon (C/C) composite finger seal experiment was performed on a high-speed seal tester. The purpose of this paper is to investigate the leakage and wear characteristics of C/C composite finger seal under various operating conditions.

Design/methodology/approach
Static, dynamic, endurance and post endurance tests were carried out. For static and performance tests, the pressure differential changed from 0.1 to 0.6 MPa and the rotor speed varied from 1,000 to 9,000 r/min. Two endurance tests were conducted for 4 h, with each mounting two finger seals. The seal leakage was monitored by mass flowmeters, and the wear depth was measured and calculated by using three-dimensional profilometer.

Findings
Results showed that the seal leakage increases with pressure differential but decreases with rotor speed. Leakage rate is lower when speed is decelerated than that with the speed stepped up. During a time history, material removal caused by wear has significant influence on leakage data causing higher leakage than the results before endurance test. Particular interest is that the uneven wear characteristic on finger foot bottom was firstly revealed, showing severe wear in foot heel area than that in foot toe.

Originality/value
This study could provide experimental guidance for finger seal designers. Additionally, the uneven wear characteristic of finger foot was firstly revealed, which showed the necessity of further theoretical research on finger seal wear.
Exploiting business networks in the age of social media: the use and integration of social media analytics in B2B marketing
Authors: Wang Yun , Rod Michel , Deng Qi , Ji Shaobo 
Published: March 2020

Purpose
Based on an organizational capability perspective, this paper aims to propose a development model for social media analytics (SMA) capability that can be applied to business-to-business (B2B) marketing, with the aim of facilitating the use and integration of SMA in B2B marketing and maximizing the benefits of business networks in the age of social media.

Design/methodology/approach
This is a critical interpretive synthesis of SMA publications collected from academic journals, business magazines and the SMA service industry. In addition, an inter-disciplinary approach was adopted by drawing upon both marketing and information systems literature. In total, 123 academic papers, 106 industry case studies and 141 magazine papers were identified and analyzed. The findings were synthesized and compiled to address the predefined research question.

Findings
An SMA capability development model is proposed. The proposed model consists of four inter-dependent levels (technological, operational, managed and strategic) that collectively transfer the technological capability of SMA to the dynamic organizational capability. Each level of SMA capability is detailed. SMA-in-B2B marketing is highlighted as a socio-technical phenomenon, in which a technological level SMA capability is emphasized as the foundation for developing organizational level SMA capabilities and organizational capabilities, in turn, supporting and managing SMA activities and practices (e.g. strategic planning, social and cultural changes, skills and resources, measurements and values).

Practical implications
The proposed research framework may have implications for the operational level SMA development and the investigations on the direct and/or indirect measurements to help firms see the impact of SMA on their business.

Originality/value
This study may have implications for the adoption, use, integration and management of SMA in B2B marketing. The proposed model is grounded on the integrated insights from academia and industry. It is particularly relevant to B2B firms that have engaged in or plan to engage in applying SMA to extract insights from their online networks and is relevant to B2B researchers who are interested in SMA, big data and information technology organization integration studies.
