Halal food export and Malaysia’s potential: the applicability of the gravity theory of trade
Authors: Ali Md. Yunus , Abdul Ghaffar Puteri Zahrah Aminan , Kabir Shahriar , Munir Sa'adiah 
Published: September 2020

Purpose
The gravity theory of trade explains the potential for trade between nations, but its application to trade in halal food has been questioned by previous studies. This study aims to investigate this issue and the role of trading partners’ economic strength and their distance from one another to identify Malaysia’s potential to export food to key halal markets.

Design/methodology/approach
The gravity theory of trade was used to examine Malaysia’s top 10 food exports to key halal markets from 2000–2017. The gravity panels were estimated using the Hausman-Taylor modelling technique to control for endogeneity within the model.

Findings
The application of the gravity theory of trade to a halal market context provides mixed results. Although the high economic strength (gross domestic product) of the trading partners enhances halal trade, the distance between the partners does not affect the volume of halal food exports. Moreover, the study identifies Malaysia’s potential to export only a few food commodities to key halal markets.

Originality/value
This study challenges the applicability of the gravity theory of trade to the halal food market. The study extends the model with additional controls for behavioural aspects and applies it to commodity-specific segregated trade in halal food. The findings underscore the need to extend the theory beyond its current focus when explaining trade opportunities in halal markets.

Authors: Giannopoulos Antonios , Piha Lamprini , Skourtis George 
Published: September 2020

PurposeDrawing on the service-dominant logic and the institutional theory, this paper aims to explore the value-creating mechanisms of branding in the destination context and the brand co-creation process at and between different levels of a service ecosystem.Design/methodology/approachAn exploratory research design was used to generate qualitative data from 18 in-depth interviews with important stakeholders and investigate how and why brand co-creation is fostered in the service ecosystem.FindingsThe study proposes a stepwise process of strategic imperatives for brand co-creation in the destination context. It presents the multi-directional flows of the brand meaning across levels of the tourism ecosystem and thereby interprets stakeholders’ efforts to co-create sustainable brands that gain prominence in the global tourism arena.Research limitations/implicationsFuture research might validate the framework in a quantitative research setting. The extended analysis of the value-creating ecosystem could investigate the role of institutions and brand value propositions across levels.Practical implicationsAcknowledging their limited control over the brand co-creation process, tourism practitioners are offered step-by-step guidance to help shape a destination brand that may retain relevance in the tourists’ minds. Critical insights are provided into resource sharing between actors and subsequent responsibilities for a sustainable destination branding strategy.Originality/valueThe paper considers the significance of the various levels in the ecosystem and the underlying mechanisms of brand co-creation in a somewhat neglected branding domain.
The social impact of the 2016 Rio Olympic Games: comparison of residents' pre- and post-event perceptions
Authors: Ribeiro Tiago , Correia Abel , Biscaia Rui 
Published: September 2020

PurposeDespite the recognition that citizens' perceptions of mega sport events' social impact is critical for the sustainable development of these events and host cities, most previous studies have not taken into consideration how these perceptions may change over time. This study examines citizens' social impact perceptions of the 2016 Rio Olympic Games before and after the event.Design/methodology/approachData were collected amongst local residents of Rio de Janeiro pre- and post-event (n = 256). A confirmatory factor analysis (CFA) analysed the psychometric properties of the proposed social impact constructs. Subsequently, a multigroup analysis and latent mean comparisons were conducted to test social impact perceptions pre- and post-event.FindingsThe multigroup CFA showed factorial stability of the social impact model in both periods, while the latent mean comparisons revealed significant differences in the dimensions of social experiences, city image and community pride enhancement, public infrastructures and social conflicts. Results indicated that the perception of positive impacts tends to increase, while perceived negative impacts decrease from pre- to post-event.Social implicationsThe social effects of hosting sport mega events result in a short-term change in attitudes towards the local community, leading to a better comprehension on how communities perceive the event's impact on their lives.Originality/valueIn a highly complex mega event such as the Olympic Games, any change may influence residents' perceptions. The findings of this study demonstrate the importance of residents for determining support or opposition in hosting the event, allowing a better understanding of the exchange effects.
Technology usage, intellectual capital, firm performance and employee satisfaction: the accountants' idea
Authors: Torre Carlo , Tommasetti Aurelio , Maione Gennaro 
Published: September 2020

PurposeThe paper proposes a conceptual integration between two variables, both considered as capable of affecting public firm performance: technology and intellectual capital.Design/methodology/approachThe analysis is performed by testing a structural equation model (SEM) which allows to measure simultaneously a plurality of variables, highlighting all the possible connections. Data is collected by administering more than 500 paper questionnaires to accountants working within Local Health Firms of Naples and Salerno.FindingsThe study seems to align with the considerations according to which intellectual capital expressed through its three dimensions – relational capital, human capital and organizational capital – exert a positive influence on perceived performance of healthcare firms, ultimately impacting on the Employees' Satisfaction.Research limitations/implicationsThe study acts as a useful guide from a managerial point of view, because it may support firm decision-making. In fact, public sector managers can leverage an instrument capable of activating functional mechanisms to improve firm performance.Originality/valueThe work allows overcoming the literature gap due to the fact that, although there is a wide recognition of the potential of technology and intellectual capital, there are no studies that synergistically integrate both the aspects in the attempt to understand their value in terms of influence on the performance of public firms, on the one hand, and on employees' satisfaction, on the other. In this vein, the work, in an attempt to provide further scientific support to the link between technology and intellectual capital, is a tool capable of highlighting how this link positively impacts on company performance and employee satisfaction.
Scalable and robust latent trajectory class analysis using artificial likelihood
Authors: Hart Kari R. , Fei Teng , Hanfelt John J. 
Published: September 2020

AbstractLatent trajectory class analysis is a powerful technique to elucidate the structure underlying population heterogeneity. The standard approach relies on fully parametric modeling and is computationally impractical when the data include a large collection of non‐Gaussian longitudinal features. We introduce a new approach, the first based on artificial likelihood concepts, that avoids undue modeling assumptions and is computationally tractable. We show that this new method provides reliable estimates of the underlying population structure and is from 20 to 200 times faster than conventional methods when the longitudinal features are non‐Gaussian. We apply the approach to explore subgroups among research participants in the early stages of neurodegeneration.
Intergenerational mobility in education: Is Africa different?
Authors: Azomahou Théophile T. , Yitbarek Eleni 
Published: September 2020

AbstractThis study analyzes the intergenerational transmission of education in nine Sub‐Saharan African countries, using nationally representative household survey data on parents of adult individuals. It provides the levels and trends of intergenerational persistence of years of schooling over 50 years, and it also ranks the nine countries relative to other nations. There is a declining cohort trend in the intergenerational persistence of education, particularly after the 1960s. Nevertheless, the education of parents remains a strong determinant of the educational outcomes of children. The analysis also documents country heterogeneity (intergenerational educational mobility varies significantly across countries) and a marked gender effect: daughter's education attainment is more correlated with her parents' education than that of sons. From a policy perspective, our result points to the importance of targeted redistributive policies and the expansion of secondary education to improve mobility.

AbstractSphingolipids constitute a class of bio‐reactive molecules that transmit signals and exhibit a variety of physical properties in various cell types, though their functions in cancer pathogenesis have yet to be elucidated. Analyses of gene expression profiles of clinical specimens and a panel of cell lines revealed that the ceramide synthase gene CERS6 was overexpressed in non–small‐cell lung cancer (NSCLC) tissues, while elevated expression was shown to be associated with poor prognosis and lymph node metastasis. NSCLC profile and in vitro luciferase analysis results suggested that CERS6 overexpression is promoted, at least in part, by reduced miR‐101 expression. Under a reduced CERS6 expression condition, the ceramide profile became altered, which was determined to be associated with decreased cell migration and invasion activities in vitro. Furthermore, CERS6 knockdown suppressed RAC1‐positive lamellipodia/ruffling formation and attenuated lung metastasis efficiency in mice, while forced expression of CERS6 resulted in an opposite phenotype in examined cell lines. Based on these findings, we consider that ceramide synthesis by CERS6 has important roles in lung cancer migration and metastasis.
‘The Hidden Holocaust’: The East Timor Alert Network (ETAN) and Human Rights Claims in Canada, 1985–1998
Authors: Torelli Julian 
Published: September 2020

AbstractThis article examines the East Timor Alert Network's (ETAN) claims‐making strategies regarding support for human rights and self‐determination of East Timor during the Indonesian occupation from 1975–1998. This research seeks to understand how ETAN attempted to persuade Canadians to care about a geographically distant horror. I examine various claims‐making strategies that ETAN used to encourage Canadian audiences to evaluate the problem as an object of public concern, the Timorese as victims deserving of their sympathy, and Canadian government as condemnation‐worthy.
Insomnia symptoms and non‐suicidal self‐injury in adolescence: understanding temporal relations and mechanisms
Authors: Latina Delia , Bauducco Serena , Tilton‐Weaver Lauree 
Published: September 2020

AbstractWe propose a theoretical model of insomnia symptoms and non‐suicidal self‐injury (NSSI) that posits bidirectional linkages. We hypothesised that heightened depressive symptoms and impulsivity that result from insomnia increase NSSI. We also posit that the shame associated with NSSI triggers repetitive negative thinking, in turn increasing insomnia. Using three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1,457; Mage = 13.2, SD = 0.43; 52.7% boys), we assessed the mediating role of depressive symptoms, impulsivity, rumination, and worry on the link between insomnia and NSSI. After controlling for depressive symptoms, we found that insomnia was related to increases in NSSI from the second to the third time point (ß23 = 0.09, p = .01). NSSI was consistently related to increased insomnia (ß12 = 0.09, p = .01; ß23 = 0.11, p < .001). In addition, depressive symptoms (ßind = 0.01, p = .02), but not impulsivity (ßind = 0.01, p = .09), mediated the path from insomnia to increased NSSI. Neither worry (ßind = 0.00, p = .59) nor rumination (ßind = 0.00, p = .96) mediated the link between NSSI and increased insomnia. We conclude that NSSI and insomnia maintain each other over time. Thus, screening adolescents for insomnia symptoms may help identify those at risk of NSSI. Although depression seems to explain why insomnia is a risk factor for NSSI, further studies should investigate why NSSI plays a role in the maintenance of insomnia. This understanding will lay the foundation for intervention.

Published: September 2020

SummaryEpicardial adipose tissue (EAT) and pericardial adipose tissue (PAT) are metabolically active fat depots implicated in cardiovascular disease, and EAT has potential as a novel cardiac risk factor, suitable as a target for interventions. The objective of this systematic review and meta‐analysis was to investigate the evidence whether EAT and PAT volume can be reduced by weight‐loss interventions (exercise, diet, bariatric surgery or pharmaceutical interventions). A systematic literature search identified 34 studies that were included in the qualitative synthesis (exercise, n = 10, diet, n = 5, bariatric surgery, n = 9 and pharmaceutical interventions, n = 10). Of the 34 studies, 10 reported sufficient data to be included in the meta‐analysis. The meta‐analysis was only conducted for changes in EAT volume, since only few controlled studies reported changes in PAT (n = 3) or total cardiac adipose tissue volume (n = 1). A significant pooled effect size (ES) for reduction in EAT volume was observed following weight‐loss interventions as compared with control interventions (ES = −0.89, 95% CI: −1.23 to −0.55, P < 0.001). When comparing the effect of exercise training versus control on EAT volume reduction, there was a significant pooled ES favouring exercise training (ES: −1.11, 95% CI: −1.57 to −0.65, P < 0.001). Similarly, the ES of pharmaceutical versus control interventions on EAT volume reduction was significant, favouring pharmaceutical interventions (ES: −0.79, 95% CI: −1.37 to −0.21, P < 0.0072). In conclusion, this systematic review and meta‐analysis provides evidence that exercise, diet, bariatric surgery and pharmaceutical interventions can reduce cardiac adipose tissue volume.

Key points
Brachial artery (BA) shear‐mediated dilatation is a widely used assessment of vascular function with links to coronary artery health and cardiovascular risk.
Cerebral vascular health is often interrogated using cerebrovascular (middle cerebral artery velocity) reactivity to carbon dioxide.
We show that endothelium‐dependent diameter (dilator) responses are not significantly related between the internal carotid artery (ICA) and BA; nor are endothelium‐independent responses.
Additionally, ICA endothelium‐dependent responses are not related to middle cerebral artery velocity or ICA blood flow reactivity responses to carbon dioxide.
Therefore, assessment of large extracranial cerebral artery vascular health should be quantified via methods specific to the vessel, not via peripheral endothelial function or cerebrovascular reactivity to carbon dioxide.
AbstractThis study compared internal carotid artery (ICA) and brachial artery (BA) endothelium‐dependent and ‐independent vasodilation. We hypothesized that endothelium‐dependent and ‐independent vasodilation of the ICA and BA would be neither similar in magnitude nor correlated between vessels. In 19 healthy adults (23 ± 6 years, 24 ± 3 kg/m2, six female), endothelium‐dependent dilatation in the ICA was determined via Duplex ultrasound during transiently elevated shear stress caused by increased partial pressure of end‐tidal carbon dioxide using dynamic end‐tidal forcing (+9 mmHg; cerebral flow‐mediated dilatation, cFMD). BA endothelium‐dependent dilatation was assessed via standard flow‐mediated dilatation (FMD). Endothelium‐independent dilatation in the ICA and BA was assessed concurrently for 10 min following administration of 400 µg sublingual glyceryl trinitrate (GTN). Endothelium‐dependent vasodilation of the ICA (3.4 ± 2.4%) was lower than (P = 0.013) and not correlated to that of the BA (7.9 ± 3.3%; r2 = 0.00, P = 0.93). Including baseline diameter and shear‐rate area under the curve as covariates maintained the difference between cFMD and FMD (3.3 ± 4.2% vs. 7.8 ± 3.8%, P = 0.03), while including baseline diameter and baseline shear rate‐adjusted area under the curve as covariates abolished it (5.9 ± 3.7% vs. 5.9.8 ± 3.5%, P = 0.99). GTN‐mediated vasodilation of the ICA (14.3 ± 2.9%) was lower than (P = 0.002) and not correlated to that of the BA (25.5 ± 8.8%; r2 = 0.12, P = 0.19). Adjusting for baseline diameter eliminated the differences in GTN‐induced vasodilation (ICA: 20.1 ± 5.8% vs. BA: 20.4 ± 5.5%; P = 0.93). Differences in endothelium‐dependent responses, and the lack of correlations between arteries, indicates that endothelium‐dependent function cannot be assumed to be related across cerebral and peripheral vasculatures in young, healthy humans.

Published: September 2020

Abstract
As a key component of wind turbine, the surface strengthening treatment of wind turbine gear is crucial to enhance its performance and service life. In the process of tooth-by-tooth induction heating, clear temperature distribution and process evolution could realize the lean control of heating effect and quality. In this article, the tooth-by-tooth heating process under the v-shaped inductor was studied to analyze the temperature field morphology and its evolution process. The results show that in the tooth profile region, the boundary morphology of the temperature field near the central section of the heating region conforms to the Boltzmann function, while the far sections conform to the normal distribution. At the end of heating, from the surface to the depth of the heating layer and from the heating center to both sides, both the maximum temperature difference and the distribution temperature are reduced. Meanwhile, the maximum temperature point near the central section is offset during the evolution of the temperature field morphology. The change of physical properties of materials and induced eddy distribution caused by involute structure and the constant change of temperature gradient are the fundamental reasons for the appearance of nonuniform temperature field and temperature excursion. The spatiotemporal variation of the hottest point was found, and the temperature morphology and evolution were revealed, which would provide a theoretical basis for adjusting the temperature distribution of tooth profile according to the requirements of different heating layers.
Brittle Crack Arrestability and Inverse Fracture in DWTT

Published: September 2020

Abstract
The drop-weight tear test (DWTT) has been widely used to evaluate the resistance of linepipe steels against brittle crack propagation, and the shear area fraction SA% in the DWTT has been adopted in the requirement for the linepipe steels. However, recent studies have pointed out the issue of ambiguity in evaluation of the DWTT when a ductile crack initiates from the notch and then transits to a brittle crack during ductile crack propagation. This fracture behavior is termed “inverse fracture.” According to the API Recommended Practice 5L3 (API RP 5L3), a test is considered invalid when a DWTT specimen shows inverse fracture. In this case, it is difficult to examine the acceptance criterion (85% shear area transition temperature) for linepipe steels. Because the purpose of the DWTT is to evaluate the brittle crack arrestability of the steels in a pressurized linepipe, the DWTT results should be examined with a propagating brittle crack arrest test. A large-scale brittle crack arrest test called the West Jefferson test is generally conducted to reproduce the crack propagation and arrest behavior in actual linepipes. However, it is somewhat difficult to control the lower test temperature and to initiate brittle crack in recent high-toughness steels in this burst test. Although the test stress conditions of the uniaxial tension in the plate tension brittle crack arrest test and the biaxial tension in a pressurized pipe are different, the plate tension brittle crack arrest test has the advantages of accurate control of the test temperature, test stress, and brittle crack initiation in comparison with the actual pipe burst test. Therefore, in this study, the brittle crack arrestability of linepipe steel which showed inverse fracture in the DWTT was investigated by conducting plate tension brittle crack arrest tests under an isothermal condition (crack arrest temperature test (CAT test)), which simulates the condition of the actual pipelines in service. This study also investigated the local shear lip thickness fraction in the CAT tests together with the shear area fraction SA% measured in DWTTs. Based on the results, the effect of brittle crack arrestability on inverse fracture appearance in the DWTTs was discussed in comparison with the brittle crack arrest behavior in the CAT tests.
