Authors: Cao Fengxiang , Yan Fengyuan , Wang Jianzhang 
Published: May 2020

Purpose
This paper aims to study the tribological properties of high strength glass fabric/phenolic laminate composites reinforced by carbon fiber (CF) with and without graphene oxide (GO) modified.

Design/methodology/approach
In this study, the tribological performance tests of the composites were conducted on a block-on-ring tester (MRH-03). The applied load, linear velocity and duration of time are 200 N, 0.5 m/s and 120 min, respectively. The friction coefficient and specific wear rate were shown.

Findings
The optimal content of GO on CFs is 0.2 per cent mass fraction. The optimal content of GO addition means the strongest interfacial adhesion between the CF and the matrix.

Originality/value
The main originality of this paper is to reveal the effect of surface GO on CF on the tribological properties of fabric-reinforced composites.

Use of effectuation by established micro businesses: short-term gain, long-term pain?
Authors: McGowan Phillip 
Published: May 2020

Purpose
The purpose of this study is to investigate the efficacy and impact of effectual logic used by owner-managers of established micro firms when making buying decisions.

Design/methodology/approach
Semi-structured interviews were conducted with 13 owner-managers of micro firms, concerning their decision-making processes when selecting suppliers. Interviews were transcribed verbatim, then analysed thematically.

Findings
This study contributes to the literature in respect of effectuation by considering its use by a micro firm owner-manager to develop relationships with trusted suppliers. The findings suggest effectuation positively promotes flexibility and reduces loss potential, thus positively affecting the price that the owner-manager is willing to pay. Furthermore, it also appears to necessitate effectual selling, with an ongoing iterative process, in which effectual selling leads to effectual buying. In contrast to extant literature, this study suggests that application of effectual logic to buying and selling decisions, by a micro firm owner-manager can create, rather than reduce, uncertainty.

Research limitations/implications
This study is based on single interviews with a sample of owner-managers of micro firms that operate within the same industry and within a single country. The subjective nature of qualitative research, homogeneity and size of sample may prevent generalisation of the findings.

Practical implications
Effectual buying and selling appears to provide a micro firm with the ability to engage with flexible suppliers so as to offer a heterogeneous array of products and services to its customers, thus promoting sales success. Yet, the lack of homogeneity of customer needs and need for supplier flexibility may lead to overall costs being greater than those that could be achieved if the micro firm specialised in a smaller range of products and services and developed internal resources to meet the needs of its customers.

Originality/value
In contrast to extant literature that states that effectuation is a way to reduce uncertainty to a level at which a decision can be made, this study suggests that continual use of effectual logic by owner-managers of micro firms when making buying and selling decisions can instead create more uncertainty in the longer term.
Climate change and business planning: solutions to keep disruptions at bay
Authors: Srikant Chethan D. , Teckchandani Atul 
Published: May 2020

Purpose
The purpose of this paper is to develop an integrative approach to help firms across multiple industries ensure operational continuity and manage ongoing climate-change related disruptions. It provides an implementation model that would first, help firms recognize this as an issue and second, start incorporating certain practices in their decision-making processes.

Design/methodology/approach
The analytical framework in this paper is based on the strategic management’s resource-based view. According to this view, certain resources provide sustainable competitive advantages because they score high on the following four dimensions: valuable, rare, inimitable and organized to exploit. This paper introduces a fifth dimension – the climate change resilience of the resource. Resources that are not always obvious choices for providing competitive advantages – air, freshwater, workspaces and customers – are evaluated. Each resource is analyzed through the perspective of two disparate industries.

Findings
This paper highlights to two important findings. First, resources that are rarely considered as providing competitive advantage can become important when the authors add the fifth dimension – climate change resilience. Second, location choices are critical to ensuring climate change resilience. When firms are location constrained, a contingency plan needs to be in place. These contingency plans could range from redesigning physical assets to redesigning human resources practices.

Originality/value
This paper illustrates the need and the utility of climate change resilience when assessing the sustainable competitive advantage of a resource. Using the above findings, this paper develops a model for implementing a location-based strategy, which firms in any industry could adopt to ensure the climate change resilience of their resources.

Published: May 2020

Purpose
This paper aims to investigate the preventive effects of a concomitant supplementation of a lyophilized aqueous extract of Globularia alypum (Ga) leaves in a high cholesterol-diet (HC-D) on lipid profile and lecithin cholesterol acyltransferase (LCAT) activity in hypercholesterolemic rats.

Design/methodology/approach
Twenty-four male Wistar rats weighing 232 ± 10 g were divided into four groups (n = 6). Two control groups were fed a standard-diet (St-D) supplemented (C-Ga) or not (C) with 1.66% Ga leaf extract. The two others experimental groups were fed HC-D, which contains the St-D plus 1% of cholesterol and 0.5% of cholic acid supplemented (HC-Ga) or not (HC) with the same amount of Ga. At d28, feces were collected and fasting rats were anesthetized; bloods and livers were removed to measure biochemical parameters.

Findings
In hypercholesterolemic (HC) rats, Ga supplementation in HC-D induced a significant reduction in ALT (−64%, p = 0.002) and AST (−71%; p = 0.005) activities, in plasma TC (−55%; p = 0.03) and TG (−54%; p = 0.01) concentrations, in cholesterol contents of atherogenic lipoproteins VLDL (−78%; p = 0.004) and LDL-HDL1 (−64%; p = 0.003) and inversely, an increase in those of anti-atherogenic HDL2 (+14%; p = 0.002). Feeding the HC-D-Ga exhibited a reduction in atherogenic index Apo B/Apo A-I (−72%; p = 0.002), an increase in faecal lipids, cholesterol excretion and in plasma apo A-I (+60%; p = 0.002) and HDL2-cholesteryl esters (+32%, p = 0.04) and then improved LCAT activity (+31%; p = 0.03).

Originality/value
In hypercholesterolemic rats, Globularia alypum extract was effective in preventing lipid disorders by its hypolipidemic action, had an anti-atherogenic potential and a protective effect against cardiovascular risk by enhancing LCAT activity.

Published: May 2020

Purpose
The purpose of this study is to evaluate the effect of Hibiscus sabdariffa ethanolic extract (HsE) on protein levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, adiponectin and leptin in adipose tissue, as well as on the lipid and glycemic profiles of high-fat/sugar diet-induced obese (DIO) rats.

Design/methodology/approach
Obesity was induced in male Wistar rats through a high-fat/sugar diet provided for eight weeks. Control rats received a standard diet. The high-fat/sugar DIO animals were subsequently randomized into DIO (n = 8) and DIO treated with HsE (DIO + HsE, n = 8, 150 mg/kg/day) by gavage, for additional eight weeks. Oral glucose tolerance test was performed, and blood samples and epididymal adipose tissue were collected for biochemical analysis and adipokine protein level evaluation, respectively.

Findings
Compared to the DIO rats, HsE treatment decreased weight gain (50.6%) and mesenteric fat (42%), indicated as diminished visceral fat (22.5%). HsE did not affect the lipid profile and TNF-α levels in adipose tissue; however, it effectively prevented a 13% increase in fasting glucose levels and improved glucose tolerance. Compared with the C group, HsE normalized the adiponectin levels and leptin/adiponectin ratio and decreased the IL-6 (55%) and leptin (18.6%) levels in adipose tissue of obese rats.

Originality/value
HsE improves adipokine protein levels in high-fat/sugar DIO rats, demonstrating the clinical efficacy of HsE in the treatment of obesity and obesity-related diseases.
Microwave radiometer for sensor systems with self-contained power supplies
Authors: Ubaychin Anton V. , Abdirasul Uulu Tilekbek , Zhuk Grigory 
Published: May 2020

PurposeThis paper aims to describe a new microwave radiometer designed for sensing natural mediums to solve various applied scientific problems. The research findings enable to make assertions about high efficiency of the described microwave radiometer being a part of mobile sensor systems with self-contained power supplies.Design/methodology/approachA new microwave radiometer is based on the modification of the null method. Modification of the null method has been implemented by using two reference noise generators. The first reference noise generator is passive and its implementation is based on the matched load. A low-noise amplifier is used as the second reference noise generator. The use of the low-noise amplifier as the reference noise generator is based on the noise wave generation effect at its input whereby the waves form low-temperature noise.FindingsThe use of the low-noise amplifier as the reference noise generator in the modified microwave radiometer has made it possible to simplify the device design at the system level while reducing the weight and power consumption and increasing sensitivity.Originality/valueThe novelty of the modified radiometer lies in the modification of the null method and the removal of high-temperature reference noise generators based on avalanche transit-time diodes. Further, the novelty lies in the invariance of measurement results toward changes in the receiver’s own noise and transmission factor while the design of the device has been simplified.
Exploring contextual factors in citizen-initiated platforms to non-functional requirements elicitation
Authors: Nascimento Ademir Macedo , da Silveira Denis Silva , Dornelas Jairo Simião , Araújo João 
Published: May 2020

Purpose
This paper aims to systematize the contextual factors that influence the intention to use citizens and governments-initiated platforms, presenting them as non-functional requirements (NFRs), to facilitate their understanding to implementers.

Design/methodology/approach
A systematic mapping of the literature was done to identify the contextual factors from citizens and governments (C2G) adoption, followed by a survey applied to 938 potential users of this type of technology. The results were analyzed through logistic regression to understand the impact of the contextual factors on the intention to use C2G platforms and then those contextual factors were formalized as NFRs represented by a Softgoal Interdependence Graph.

Findings
Among the results, the most prominent factors were the influence of the “users perceived contribution” and the “citizens concern about the city conditions”. Finally, some strategies are suggested to help public managers and developers to optimize the factors that have shown to be significant.

Practical implications
This study can support e-gov policies in the implementation of C2G platforms because several municipalities need assistance in taking actions to foster greater citizens’ engagement. An example of this type of contribution is the indication of the factors of greatest impact in the adoption of use and the indication of paths to be followed if the manager and developers decide to focus on each of them.

Originality/value
The identification of several contextual factors which influence C2G platforms adoption and their systematization with the purpose of jointly visualizing and evaluating them.
Defending the European court of human rights: Experimental evidence from Britain
Authors: DINAS ELIAS , GONZALEZ‐OCANTOS EZEQUIEL 
Published: May 2020

AbstractAs nationalist sentiments gain traction globally, the attitudinal and institutional foundations of the international liberal order face new challenges. One manifestation of this trend is the growing backlash against international courts. Defenders of the liberal order struggle to articulate compelling reasons for why states, and their citizens, should continue delegating authority to international institutions. This article probes the effectiveness of arguments that emphasise the appropriateness and benefits of cooperation in containing preferences for backlash among the mass public. We rely on IR theories that explain why elites create international institutions to derive three sets of arguments that could be deployed to boost support for international courts. We then use experimental methods to test their impact on support for backlash against the European Court of Human Rights in Britain (ECtHR). First, in line with principal‐agent models of delegation, we find that information about the court's reliability as an ‘agent’ boosts support for the ECtHR, but less so information that signals Britain's status as a principal. Second, in line with constructivist approaches, associating support for the court with the position of an in‐group state like Denmark, and opposition with an out‐group state like Russia, also elicits more positive attitudes. This finding points to the importance of ‘blame by association’ and cues of in/out‐group identity in building support for cooperation. The effect is stronger when we increase social pressure by providing information about social attitudes towards Denmark and Russia in Britain, where the public overwhelmingly trusts the Danes and distrusts the Russians. Finally, in contrast to Liberal explanations for the creation of the ECtHR, the study finds no evidence that highlighting the court's mission to promote democracy and international peace contains backlash. We show that the positive effects of the first two arguments are not driven by pre‐treatment attitudes such as political sophistication, patriotism, internationalism, institutional trust or political preferences.
Takeaway food, waste, and their geographies in workplaces
Authors: Liu Chen , Chen Jiaxi 
Published: May 2020

AbstractThis article draws on empirical research to develop an understanding of the social and cultural geography of food and its waste in the workplace. Our aim is to contribute to the wider body of literature on everyday geographies of waste and wasting in relation to food, paying attention to the complex trajectories of the disposal of the waste produced by food consumption beyond the scale of the household. On that basis, the work explores the distinct ways in which the waste produced by takeaway food consumption is managed in workplaces and examines how food consumption and wasting manifest in relation to both workplace contexts and wider sociocultural and material factors in urban China. Such matters are still under‐researched there. Specifically, we identify the different conduits through which food and food packaging become waste in workplaces. Food is transformed into waste soon after it becomes surplus, whereas food packaging becomes waste through two conduits: the conventional way of binning and the alternative way of reusing.
Everyday life after downshifting: Consumption, thrift, and inequality
Authors: Lindsay Jo , Lane Ruth , Humphery Kim 
Published: May 2020

AbstractMuch of the early literature on downshifting proposed that reduced hours at work would lead to reduced levels of consumption, increased hours of leisure, and a more sustainable and fulfilling life, and yet recent survey research has challenged these assumptions. Our study contributes knowledge on the differentially lived experience of contemporary downshifting and its relationship to sustainable and/or thrifty consumption. We undertook qualitative interviews with Australians of working age who had voluntarily reduced their hours of work in order to explore the everyday experience of downshifting and its links with consumption practices in the domains of food, leisure, and transport. These downshifters focused on thrift rather than sustainability and consequently did not reduce their consumption in a straightforward way. We found the everyday experience of downshifting was significantly shaped by caring responsibilities and financial and housing security. Moreover, differential levels of financial security affected consumption levels. Although those with lower levels of wealth closely managed discretionary expenditure, financially secure downshifters did not reduce their consumption overall. We argue that reduced working hours are unlikely to lead to reduced consumption in the absence of an ideological commitment to sustainability and without mainstream support for changing consumption mindsets and practices.
The Proof is Not in the EATing
Authors: Thorkildsen Trine , Reksnes Dag Henning 
Published: May 2020

SummaryOne of the most widely discussed reports addressing sustainable food production and healthy diets is Food in the Anthropocene: the EAT‐Lancet Commission on Healthy Diets from Sustainable Food Systems (EAT‐Lancet) launched in January 2019. The report is stated to be based on best available science but unfortunately the methodology applied is not transparent or in alignment with certain scientific standards. The diet prescribed by EAT‐Lancet is based on health considerations alone, before looking at certain environmental aspects, but no description is given as to how the very specific intake levels for each food were set. The diet is especially restrictive for animal sourced foods, even though evidence‐based dietary guidelines in many countries have concluded that these foods can be part of a health‐promoting diet. Furthermore, an independent review has found several flaws and weaknesses in the report. EAT‐Lancet also fails to account for national differences in natural opportunities for food production. Implementation of their recommendations will make many countries more reliant on imports which contrast with the recommendations by the FAO and the IPCC. Taking these issues into account warrants caution before taking on trust the recommendations by EAT‐Lancet into business and policy.

Published: May 2020

AbstractTea, a popular aromatic infusion and food supplement, prepared from Camellia sinensis (L.) Kuntze leaves, is often subjected to adulteration with various undeclared inorganic and plant‐derived materials. Cashew (Anacardium occidentale L.) nut husk is one of the most common plant tea adulterants. To date, there are limited DNA‐based technologies for tea authentication and quantitative detection of adulterants. Herein, we used a universal plant DNA barcoding marker coupled with High Resolution Melting (Bar‐HRM) analysis to authenticate tea products from cashew ground nut. Additionally, cashew‐specific markers coupled with HRM technology were used to detect and quantify adulteration of tea with cashew DNA. This methodology can reliably detect admixtures as low as 1% v/v cashew in commercial tea products. Overall, our results demonstrate that the HRM technology is a strong molecular approach in tea authentication, capable of detecting very low adulterations in DNA admixtures.Practical ApplicationIn this study, we established the use of high‐resolution DNA‐based technologies for the detection of cashew adulteration in tea, even in very low quantities. The technology could be applied to a greater range of plant‐based tea adulterants. This work is expected to facilitate the traceability and authenticity of tea products and form the basis for the development of strategies against fraudulent practices.

Published: May 2020

AbstractMucin 2 (MUC2) is the skeleton of colonic mucus that comprises the physical intestinal barrier. Different dietary polysaccharides may affect colonic mucus at different extents. The effect of pectin on MUC2 production is contradictory. To investigate whether and how pectin affected hosts’ colonic mucus, the amount of MUC2 in colon, the cecal, mucosal microbiota, and metabolites profiles were analyzed and compared with inulin. The results showed pectin stimulated the production of MUC2 at a similar level to inulin. Both interventions increased the abundance of cecal Lachnospira and Christensenellaceae_R‐7_group, and enhanced the production of specific metabolites including soyasapogenol B 24‐O‐b‐d‐glucoside, lucyoside Q, trans‐EKODE‐(E)‐Ib, and 1,26‐dicaffeoylhexacosanediol. Additionally, pectin increased the relative abundance (RA) of cecal Lactobacillus, and induced less RA of potentially harmful bacteria such as Helicobacter in mucosal microbiota than inulin. In conclusion, we first reported that pectin and inulin stimulated the mucus formation at a similar level. Two genera of cecal bacteria and four metabolites may play an important role in enhancing the production of MUC2. Moreover, the MUC2 production may be unrelated to several traditional health‐beneficial bacteria; pectin possibly performed as good as or better than the inulin in rats’ gut.
