An empirical study on the correlation between teacher efficacy and ICT infrastructure
Authors: Kundu Arnab , Bej Tripti , Dey Kedar Nath 
Published: September 2020

PurposeSelf-efficacy is one's belief in one's ability. In this context, information and communication technology (ICT) self-efficacy is the judgment of one's capability to use ICT – the familiar and effective teaching tools for the 21st century classrooms. The purpose of this empirical study was to investigate the correlation between teachers' ICT self-efficacy and perceived ICT infrastructure in school.Design/methodology/approachThe study employed a descriptive survey method within ex post facto research design by taking 100 purposively selected Indian government run secondary schools and 400 teachers as participants. The data were analyzed descriptively and inferentially. A correlation analysis was conducted between teachers' ICT self-efficacy and their perception of ICT infrastructure to determine the relationship between the two.FindingsFindings revealed that the participant teachers' overall ICT self-efficacy along with its three domains – technological efficacy, pedagogical efficacy, integration efficacy – was moderately low and their perception of ICT infrastructure in their respective schools was also far below the expected level. The investigation finally found a moderately high and positive correlation between teachers' ICT self-efficacy and their overall perception of ICT infrastructure. All three domains of efficacy also found positively correlated with the three selected domains of ICT infrastructure.Originality/valueThis paper reports an original empirical survey conducted in India and the write-up is based strictly on the survey findings only. The authors believe this is a new approach to view ICT integration in school pedagogy and recommendations that enhanced teacher efficacy accelerates strengthening ICT infrastructure, improving apposite culture and understanding of the pedagogical value of ICT integrated teaching.
Place, mobility and social support in refugee mental health
Authors: Nolas Sevasti-Melissa , Watters Charles , Pratt-Boyden Keira , Maglajlic Reima Ana 
Published: September 2020

Purpose
This review and theoretical analysis paper aims to bring together literatures of place, mobility, refugees and mental health to problematise the ways in which social support is practised on the ground and to rethink its possibilities.

Design/methodology/approach
This paper draws on an interdisciplinary understanding of social support that focusses on the social networks and significant and intimate relationships that mitigate negative mental health and well-being outcomes. The authors explore the dialectic relationship between place and mobility in refugee experiences of social support.

Findings
The authors argue that, in an Euro-American context, practices of social support have historically been predicated on the idea of people-in-place. The figure of the refugee challenges the notion of a settled person in need of support and suggests that people are both in place and in motion at the same time. Conversely, attending to refugees’ biographies, lived experiences and everyday lives suggests that places and encounters of social support are varied and go beyond institutional spaces.

Research limitations/implications
The authors explore this dialectic of personhood as both in place and in motion and its implications for the theorisation, research and design of systems of social support for refugees.

Originality/value
This paper surfaces the dialectics of place and mobility for supporting refugee mental health from an interdisciplinary perspective.
How innovation intermediaries support start-up internationalization: a relational proximity perspective
Authors: Schepis Daniel 
Published: September 2020

Purpose
This paper aims to examine how innovation intermediary activities increase relational proximity between start-ups and foreign partners to support start-up internationalization.

Design/methodology/approach
The paper applies a case study methodology to examine an international network of innovation intermediaries in the resources sector. Interviews were conducted with 59 start-ups, corporate and intermediary managers in four countries, supplemented by secondary data. A two-stage analysis process was performed to first identify activities relating to start-up internationalization and then apply a theoretically derived coding framework based on five proximity dimensions.

Findings
The case identifies several innovation intermediary activities, which facilitate relationship development between start-ups and partners in new markets. Findings outline how activities increase relational proximity across different dimensions, while also indicating a number of interrelations between dimensions, given the complexity of international business relationships.

Originality/value
This paper establishes interdisciplinary bridges between business networks, international business and economic geography perspectives. It provides a valuable empirical foundation for relational proximity, demonstrating its application to understanding start-up internationalization and its influence by intermediary-led activities.
The impacts of a new type of actor as an intermediary in public–private collaboration in health-care prevention
Authors: Dóra Tímea Beatrice , Szalkai Zsuzsanna 
Published: September 2020

Purpose
This paper aims to investigate the dyadic relationships of actors engaged in public–private (P-P) collaboration in health-care prevention. The purpose is to characterize a new type of actor as an intermediary that connects different actors in P-P collaboration and to compare P-P collaboration based on results expected with and without the inclusion of this new actor.

Design/methodology/approach
For the investigation, the Industrial Marketing and Purchasing Group approach to business relationships is used. The substance (activities-resources-actors) and the functions (dyadic, single actor and network) of business relationships are applied as a research framework. The analysis is based on these theories through a case study.

Findings
This study delivers four important findings: the relationship with this new type of actor results in new resources for all of the participants that are involved, the new actor is a key channel for generating corporate social responsibility recommendations for private actors, relationships with this new type of actor are a great basis on which private firms may build relationships with the public that involve higher levels of health care and also generate sponsorship for public causes, thereby increasing social welfare and the new type of actor can cause potential tensions that require constant and coordinated management.

Originality/value
The paper contributes to the conceptualization of the “interacted actor” through characterizing a new type of actor and its renewing network in P-P collaboration.
Equity market-related economic uncertainty and the “economic contagion phenomenon”
Authors: Abaidoo Rexford , Alade Ayodele 
Published: September 2020

PurposeThis study examines potential causal interactions between a dominant economy and its trading partners, with the view of verifying surmised economic contagion effects traditionally presumed to emanate from dominant economies toward trading partners.Design/methodology/approachThe study used the Toda–Yamamoto Wald test approach to bi-variate causality analysis.FindingsThis study verified the existence of the economic contagion phenomenon; Estimated empirical evidence failed to fully support the presumption that such contagion effects mostly emanates from dominant economies toward trading partners, all things being equal. For instance, although this study found significant economic contagion effects emanating from the US economy toward the Chinese economy, the authors also detected six different uni-directional causal interactions with the direction of causality emanating from trading partners toward the US economy.Originality/valueThe uniqueness of this study stems not from its verification of the economic contagion phenomenon using equity market-related economic uncertainty as the potential contagion. This study fills a gap in the present literature by focusing on the happenings in the equity market as the potential candidate of the economic contagion phenomenon between a dominant economy and its key trading partners.
Simulation training for police and ambulance services to improve mental health practice
Authors: Uddin Tasnim , Saadi Amina , Fisher Megan , Cross Sean , Attoe Chris 
Published: September 2020

Purpose
Emergency services face increasing frontline pressure to support those experiencing mental health crises. Calls have been made for police and ambulance staff to receive training on mental health interventions, prevention of risk and inter-professional collaboration. Mental health simulation training, a powerful educational technique that replicates clinical crises for immersive and reflective training, can be used to develop competencies in emergency staff. This study aims to evaluate the effectiveness of mental health simulation training for police and ambulance staff.

Design/methodology/approach
In total, 199 participants from the London Metropolitan Police Service and London Ambulance Service attended a one-day simulation training course designed to promote effective and professional responses to mental health crises. Participants took part in one of six simulated scenarios involving mental health crisis before completing structured debriefs with expert facilitators. Participants’ self-efficacy and attitudes towards mental illness were measured quantitatively using pre- and post-course questionnaires while participants’ perceived influence on clinical practice was measured qualitatively using post-course open-text surveys.

Findings
Statistically significant improvements in self-efficacy and attitudes towards mental illness were found. Thematic analyses of open-text surveys found key themes including improved procedural knowledge, self-efficacy, person-centred care and inter-professional collaboration.

Originality/value
This study demonstrates that mental health simulation is an effective training technique that improves self-efficacy, attitudes and inter-professional collaboration in police and ambulance staff working with people with mental health needs. This technique has potential to improve community-based responses to mental health crises.
Mega-events brand meaning co-creation: the Olympic case
Authors: Tjandra Nathalia Christiani , Rihova Ivana , Snell Sarah , Den Hertog Claire S. , Theodoraki Eleni 
Published: September 2020

Purpose
This paper aims to explore a multi-stakeholder perspective on brand meaning co-creation in the context of the Olympic Games as a unique mega sports event brand with a strong brand identity, to understand how the brand manager may integrate such co-created meanings in a negotiated brand identity.

Design/methodology/approach
Using a qualitative methodology, the paper provides a tentative framework of co-created Olympic brand meanings by exploring the narratives of stakeholders’ brand experiences of the brand. Sixteen semi-structured interviews with a purposive sample of Olympic stakeholders were conducted and analysed to identify key meanings associated with the Olympic brand.

Findings
Through their transformational and social experiences of the Olympic brand, stakeholders co-create brand meanings based on Olympic values of excellence, friendship and respect. However, at the same time, they offer their own interpretations and narratives related to competing meanings of spectacle, exclusion and deceit. Alternative brand touchpoints were identified, including blogs; fan and sports community forums; educational and academic sources; and historical sources and literature.

Practical implications
The brand manager must become a brand negotiator, facilitating multi-stakeholder co-creation experiences on a variety of online and offline engagement platforms, and exploring how alternative brand touchpoints can be used to access co-created brand meanings.

Originality/value
The study contributes to tourism branding literature by providing exploratory evidence of how brand meanings are co-created in the relatively under-researched multi-stakeholder sports mega-event context.

Published: September 2020

Purpose
This paper aims to present the capacitance characterization of tapered dielectrophoresis (DEP) microelectrodes as micro-electro-mechanical system sensor and actuator device. The application of DEP-on-a-chip (DOC) can be used to evaluate and correlate the capacitive sensing measurement at an actual position and end station of liquid suspended targeted particles by DEP force actuator manipulation.

Design/methodology/approach
The capability of both, sensing and manipulation was analysed based on capacitance changes corresponding to the particle positioning and stationing of the targeted particles at regions of interest. The mechanisms of DEP sensor and actuator, designed in DOC applications were energized by electric field of tapered DEP microelectrodes. The actual DEP forces behaviour has been also studied via quantitative analysis of capacitance measurement value and its correlation with qualitative analysis of positioning and stationing of targeted particles.

Findings
The significance of the present work is the ability of using tapered DEP microelectrodes in a closed mode system to simultaneously sense and vary the magnitude of manipulation.

Originality/value
The integration of DOC platform for contactless electrical-driven with selective detection and rapid manipulation can provide better efficiency in in situ selective biosensors or bio-detection and rapid bio-manipulation for DOC diagnostic and prognostic devices.
Resource partitioning among avian predators of the Arctic tundra
Authors: Seyer Yannick , Gauthier Gilles , Fauteux Dominique , Therrien Jean‐François 
Published: September 2020

Abstract

Interspecific competition can play a key role in structuring ecological communities. The Arctic tundra is a low productivity ecosystem supporting simple food webs, but several predators often feed on the same prey species, lemmings, known for their large‐amplitude population fluctuations.

We examined mechanisms involved in reducing intra‐guild competition and allowing coexistence of four avian predators (snowy owls, glaucous gulls, rough‐legged hawks and long‐tailed jaegers) feeding on a pulsed resource (brown and collared lemmings). We compared the size and species of prey consumed by predators to see if resource partitioning occurred. We also verified if spatial segregation in nesting areas could be another mechanism allowing coexistence. Finally, we tested if the absence of the snowy owl, a dominant and irruptive species, triggered a competitive release on the smallest predator, the jaeger, with respect to prey size and nesting area used.

We monitored the breeding of predators and lemming abundance over a 14‐year period on Bylot Island, Canada. We mapped their nesting sites and collected regurgitation pellets to recover lemming mandibles, which were used to infer prey species and size.

The size of lemmings consumed varied among species with the largest predators consuming the largest lemmings and the smallest predators consuming the smallest lemmings. All predators consumed more collared than brown lemmings compared to their availability although owls and jaegers consumed relatively more brown lemmings compared to gulls and hawks. Jaegers consumed larger lemmings in the absence of owls than in their presence, suggestive of a short‐term competitive release. We found moderate to low overlap in nesting areas among predators and no evidence of their expansion in the absence of owls, suggesting that spatial distribution is caused by species‐specific habitat preferences.

The main mechanism to partition food resources among these avian predators is spatial segregation, and secondarily prey size and species. However, we found evidence that food competition is still present and leads to a niche shift in the smallest predator of the guild. Interspecific competition may thus be a pervasive force in simple, low productivity food webs characterized by pulsed resources.
When form does not predict function: Empirical evidence violates functional form hypotheses for marine macroalgae
Authors: Ryznar Emily R. , Fong Peggy , Fong Caitlin R. 
Published: September 2020

Abstract

Functional groups are widely used to reduce complexity and generalize across ecological communities. These models assume that shared traits among species correspond to some ecological role, process or function, and that these traits can be leveraged to generate meaningful and distinct functional groups so that intergroup trait variation exceeds intragroup variation.

We sought to validate the assumptions of the widely used functional group model (FGM) for marine macroalgae, which groups species based on morphological complexity, by testing the predictions of the FGM for several traits assumed to correspond with morphological complexity. The FGM predicts increased resistance to disturbance and herbivory as morphological complexity (tensile strength and thallus toughness, respectively) increases. The FGM also predicts a trade‐off between complexity and growth rate. To test predictions, we measured (a) thallus toughness (force to penetrate), (b) tensile strength (force to break) and (c) relative growth for both tropical and temperate macroalgae from different functional groups.

Thallus toughness followed model predictions at the functional group level, though there was significant variability among species. However, the model did not predict tensile strength at any level for either tropical or temperate macroalgae. Furthermore, relative growth did not follow predictions; rather it was highly variable among species and functional groups.

Synthesis. The assumptions of the FGM that differences in morphological complexity can be used to generate distinct functional groups and that intergroup trait variation outweighs intragroup variation were violated, providing strong evidence that individual species responses need to be considered. Furthermore, violations of assumptions indicate that functional groups should not be used to predict community responses to ecological drivers and/or species contributions to ecosystem function. Our study challenges the usefulness of functional form groups for marine macroalgae and emphasizes the need for a different conceptual framework.

Published: September 2020

BackgroundThe significant number of qualitative and quantitative ultrasound markers described for first‐trimester screening of open spina bifida (OSB) and other posterior brain defects (oPBD) has resulted in their complex implementation and interpretation for a widespread screening and in a lack of consensus regarding diagnostic accuracy.ObjectivesTo assess and compare the accuracy of qualitative and quantitative cranial sonographic markers at 11–14 weeks of gestation for the detection of OSB and oPBD.Search strategyA systematic literature search was performed in MEDLINE and COCHRANE from 2009 to April 2020.Selection criteriaStudies assessing the diagnostic accuracy of quantitative and/or qualitative ultrasound signs to predict OSB and oPBD were included. Cohort studies and case–control studies were also considered.Data collection and analysisTwo reviewers independently extracted data and assessed the risk of bias. The overall pooled estimate and a summary receiver operating characteristic curve was estimated for each subgroup (qualitative and quantitative assessment).Main resultsTwenty‐three studies were included in our meta‐analysis. The pooled sensitivity and specificity for qualitative assessment were 76.5% and 99.6%, and for quantitative assessment were 84.5% and 96.3%, respectively; specificity for the qualitative ultrasound signs was significantly higher (P = 0.001). The overall sensitivity of cranial sonographic markers for the screening of oPBD was 76.7% and specificity was 97.5%.ConclusionsThe qualitative approach demonstrated greater specificity, so this would appear to be more appropriate for daily screening, as a first‐line tool, whereas the quantitative approach should be reserved for expert ultrasound.Tweetable abstractThis study highlights the relevance of first‐trimester qualitative ultrasound signs in the screening of open spina bifida.

Published: September 2020

AbstractObjectiveTo develop novel, scalable, and valid literacy profiles for identifying limited health literacy patients by harnessing natural language processing.Data SourceWith respect to the linguistic content, we analyzed 283 216 secure messages sent by 6941 diabetes patients to physicians within an integrated system's electronic portal. Sociodemographic, clinical, and utilization data were obtained via questionnaire and electronic health records.Study DesignRetrospective study used natural language processing and machine learning to generate five unique “Literacy Profiles” by employing various sets of linguistic indices: Flesch‐Kincaid (LP_FK); basic indices of writing complexity, including lexical diversity (LP_LD) and writing quality (LP_WQ); and advanced indices related to syntactic complexity, lexical sophistication, and diversity, modeled from self‐reported (LP_SR), and expert‐rated (LP_Exp) health literacy. We first determined the performance of each literacy profile relative to self‐reported and expert‐rated health literacy to discriminate between high and low health literacy and then assessed Literacy Profiles’ relationships with known correlates of health literacy, such as patient sociodemographics and a range of health‐related outcomes, including ratings of physician communication, medication adherence, diabetes control, comorbidities, and utilization.Principal FindingsLP_SR and LP_Exp performed best in discriminating between high and low self‐reported (C‐statistics: 0.86 and 0.58, respectively) and expert‐rated health literacy (C‐statistics: 0.71 and 0.87, respectively) and were significantly associated with educational attainment, race/ethnicity, Consumer Assessment of Provider and Systems (CAHPS) scores, adherence, glycemia, comorbidities, and emergency department visits.ConclusionsSince health literacy is a potentially remediable explanatory factor in health care disparities, the development of automated health literacy indicators represents a significant accomplishment with broad clinical and population health applications. Health systems could apply literacy profiles to efficiently determine whether quality of care and outcomes vary by patient health literacy; identify at‐risk populations for targeting tailored health communications and self‐management support interventions; and inform clinicians to promote improvements in individual‐level care.
