Authors: Mkansi Marcia , de Leeuw Sander , Amosun Olatoye 
Published: November 2019

Purpose
The purpose of this paper is to present a mobile application supported townshipand urban e-grocery distribution models that uses a software application (app) to bridge the infrastructural barriers, costs and complexities associated with e-grocery delivery operations in rural township areas.

Design/methodology/approach
Using a qualitative multi-case approach and semi-structured interviews, the study explored distribution practices of eight national emerging e-grocery retail businesses to demonstrate how mobile applications can facilitate South African urban and township e-grocery delivery models.

Findings
The study reveals how the need to scale the use of new mobile application innovations fuels value-added services that power new e-grocery distribution models. Of interest is how the application aggregates demand rapidly, respond to demand within a short lead time and how e-grocers use competitors’ stores as their fulfilment centres. The use of apps reveals a slow transformation of society towards an inclusive model that integrates different types of workers in an informal context.

Practical implications
The mobile application value-added service business model offers a new wave of scaling e-grocery retail to rural and township areas constrained by technological, economic and road infrastructure. The apps transcend e-grocery barriers and enables small businesses with limited resources to leverage e-grocery market opportunities that are unimaginable in townships and rural areas.

Originality/value
The innovative mobile platform-base model offers emerging contextual insight of a pull e-grocery distribution model that demonstrates the supply chain innovations for addressing under-resource and under-developed logistics infrastructure.

Value co-destruction: a typology of resource misintegration manifestations
Authors: Laud Gaurangi , Bove Liliana , Ranaweera Chatura , Leo Wei Wei Cheryl , Sweeney Jill , Smith Sandra 
Published: November 2019

Purpose
Actors who participate in co-created service experiences typically assume that they will experience improved well-being. However, a growing body of literature demonstrates that the reverse is also likely to be true, with one or more actors experiencing value co-destruction (VCD), rather than value co-creation, in the service system. Building on the notion of resource misintegration as a trigger of the VCD process, this paper offers a typology of resource misintegration manifestations and to present a dynamic conceptualization of the VCD process.

Design/methodology/approach
A systematic, iterative VCD literature review was conducted with a priori aims to uncover the manifestations of resource misintegration and illustrate its connection to VCD for an actor or actors.

Findings
Ten distinct manifestations of resource misintegration are identified that provide evidence or an early warning sign of the potential for negative well-being for one or more actors in the service system. Furthermore, a dynamic framework illustrates how an affected actor uses proactive and reactive coping and support resources to prevent VCD or restore well-being.

Originality/value
The study presents a typology of manifestations of resource misintegration that signal or warn of the potential for VCD, thus providing an opportunity to prevent or curtail the VCD process.

AbstractPsoriasis is a T‐helper (Th)1/Th17‐mediated, chronic inflammatory dermatitis that is commonly treated with topical corticosteroids and vitamin D3 analogs. The combination of a topical corticosteroid and vitamin D3 analog showed superior efficacy to each alone in clinical trials; however, the mechanisms by which the topical corticosteroid and vitamin D3 analog exert their effects on lesional skin in combination and each alone remain unknown. In this study, we examined the effects of combined calcipotriol (Cal)/betamethasone dipropionate (BD) ointment on psoriasis in vivo, utilizing imiquimod (IMQ)‐induced murine psoriasiform skin inflammation, compared with each alone. Vehicle, Cal/BD, Cal or BD was applied on the shaved back skin for 3 consecutive days. Then, IMQ was applied for 6 consecutive days. Twenty‐four hours after the last IMQ treatment, the murine skin was evaluated clinically and pathologically. mRNA expressions were examined by quantitative polymerase chain reaction. All ointments alleviated IMQ‐induced psoriasiform skin inflammation clinically in comparison with vehicle application. Cal/BD suppressed mRNA expressions of cytokines involved in psoriasis pathogenesis such as interleukin (IL)‐17A and IL‐22 efficiently. Cal alone induced IL‐10 expression, whereas BD alone reduced IL‐6 mRNA expression and the number of phosphorylated signal transducer and activator of transcription 3‐positive cells in lesional skin. Our study revealed that Cal and BD have different effects on IMQ‐induced psoriasiform skin. Some of the immune effects of Cal and BD may be additive or synergistic, which may account for the superior clinical efficacy of their combination.
Estimation of the seismic wavelet through homomorphic deconvolution and well log data: application on well‐to‐seismic tie procedure

Published: November 2019

ABSTRACTWavelet estimation and well‐tie procedures are important tasks in seismic processing and interpretation. Deconvolutional statistical methods to estimate the proper wavelet, in general, are based on the assumptions of the classical convolutional model, which implies a random process reflectivity and a minimum‐phase wavelet. The homomorphic deconvolution, however, does not take these premises into account. In this work, we propose an approach to estimate the seismic wavelet using the advantages of the homomorphic deconvolution and the deterministic estimation of the wavelet, which uses both seismic and well log data. The feasibility of this approach is verified on well‐to‐seismic tie from a real data set from Viking Graben Field, North Sea, Norway. The results show that the wavelet estimated through this methodology produced a higher quality well tie when compared to methods of estimation of the wavelet that consider the classical assumptions of the convolutional model.

Abstract

Theoretical models indicate that the structure of plant–pollinator networks has important implications for the reproduction and survival of species. However, despite the growing information on the mechanisms underlying such a structure, it is still difficult to predict the functional consequences of species’ structural positions in these networks. From the plant perspective, species position and roles in pollination networks might be related to traits describing flower attractiveness, availability and dependence on pollinators. In turn, both network metrics and plant traits might influence plant species fitness.

During two field seasons, we collected data from the 23 most abundant plant species in a rich coastal community, to evaluate the association between population and floral traits (floral abundance at population level and flowers per individual, flower shape and size, flowering length, nectar volume, pollinator dependence), species‐level network metrics (linkage level, specialization –d′–, weighted closeness centrality, network roles related to modularity) and plant fitness (seeds/flower, seed weight).

Flowering length, flower size, flower abundance and pollinator dependence were positively related to greater generalization, as measured by various indices. More abundant species and those with larger flowers showed higher linkage levels (i.e. higher number of pollinator species), whereas longer flowering periods were negatively related to d′ and positively related to closeness centrality and important roles in the network. Likewise, plants species more dependent on pollinators occupied more central positions in the network. Furthermore, centrality in the networks was significantly associated with plant fitness. Specifically, central species in the network produced more and heavier seeds than the others. However, other plant traits, such as flower size and pollinator dependence had additional direct effects on seed production.

Synthesis. Our study highlights how population and floral traits define the positions and roles of species structuring the pollination communities. Moreover, the relationships between network metrics and plant reproduction indicate, for the first time, the functional implications of these structural positions at the interspecific level of community assembly.

Published: November 2019

The present study explored the possibilities of using Bacillus coagulans as a probiotic culture in vacuum‐dried milk powder. The operational drying temperature at 63 ± 2 °C under 0.7 kg/cm2 pressure emerged as the best temperature at which to prepare dried milk powder within 4.5 h with a mean (±SEM) Bacillus coagulans B37 spore count of 8.78 ± 0.03 log cfu/g and moisture content of 4.82 ± 0.12%. The total spore counts in vacuum‐dried milk powder did not change (P > 0.10) at storage temperatures of 7 °C, 37 °C or 45 °C over a three‐month period.

ObjectiveTo determine variations in cord blood gas (CBG) parameters after 3‐minute delayed cord clamping (DCC) in vaginal deliveries (VDs) and caesarean deliveries (CDs) at term without fetal distress.DesignProspective observational study.SettingUniversity hospital.SampleCBG from 97 VDs and 124 CDs without fetal distress.MethodsComparison of paired arterial–venous CBG parameters drawn at birth from the unclamped cord and after 3‐minutes DCC for VDs and CDs.Main outcome measuresBase excess, bicarbonate, haematocrit and haemoglobin from both arterial and venous cord blood, lactate, neonatal outcomes, partial pressure of oxygen (pO2), partial pressure of carbon dioxide (pCO2), pH, and postpartum haemorrhage.ResultsArterial cord blood pH, bicarbonate (, mmol/l), and base excess (BE, mmol/l) decreased significantly after 3‐minute DCC both in VDs (pH = 7.23 versus 7.27; P < 0.001; = 23.3 versus 24.3; P = 0.004; BE = −5.1 versus −2.9; P < 0.001) and CDs (pH = 7.28 versus 7.34; P < 0.001; = 26.2 versus 27.2; P < 0.001; BE = −1.5 versus 0.7; P < 0.001). After 3‐minute DCC, pCO2 increased in CDs only (57 versus 51; P < 0.001), whereas lactate increased more in CDs compared with VDs (lactate, +1.1 [0.9, 1.45] versus +0.5 [−0.65, 2.35]; P = 0.01). Postpartum maternal haemorrhage, neonatal maximum bilirubin concentration, and need for phototherapy were similar between the two groups. Newborns born by CD more frequently required postnatal clinical monitoring or admission to a neonatal intensive care unit.ConclusionsAfter 3‐minute DCC, the acid–base status shifted towards mixed acidosis in CDs and prevalent metabolic acidosis in VDs. CDs were associated with a more pronounced increase in arterial lactate, compared with VDs.Tweetable abstractBy 3‐minute DCC, acid–base status shifts towards mixed and metabolic acidosis in caesarean and vaginal delivery, respectively.

Published: November 2019

AbstractThe fall armyworm Spodoptera frugiperda recently invaded China, ravaging crops in many provinces. Deciphering the possible genetic basics for its successful invasion is critical for innovative and specific control for this gluttonous pest. Here we generated comparative genomic analyses between S. frugiperda and its native relative, S. litura, which differs in host preference, locomotivity and production behavior. We demonstrated that S. frugiperda genes are enriched in taste sensory perception and nervous system, obviously different from those of S. litura. Potential host adaptation genes showed generally an elevated ratio of non‐synonymous substitution rate to synonymous substitution rate, suggesting a faster evolution during the divergence of the two species. Focusing on these sets of genes, we identified 23 genes being under positive selection in S. frugiperda. Among them are two notable genes involved in sensory perception, gustatory receptor (GR) and an acetaldehyde oxidase, which are important for host detection in invasion and expansion processes. Another two genes are mitochondrial adenosine triphosphate synthase β subunit and ferritin heavy chain, which may be associated with the enhanced locomotivity and resistance, which fascinated long‐distance migration needed for invasion and rapid expansion. Another interesting gene is chorion protein, in which positive selection sites in S. frugiperda were found and a replacement in one site is predicted to affect the protein function, which might be associated with competent reproductivity in S. frugiperda to ensure genetic resources for expansion.
Effect of Processing Conditions, Biochemical Properties, and Microstructure on Tofu Production from Yellow Field Peas (Pisum sativum)
Authors: DePalma Kevin , Smith Brennan , McDonald Armando G. 
Published: November 2019

AbstractTofu, made by coagulating soy milk, is a nutritious food originating in China and is widely consumed globally. Due to allergenicity and consumer perceptions of genetically modified organisms, consumer demand for soy alternatives is increasing. In this study, tofu was made from yellow split peas (Pisum sativum). Effects of pasteurization, fat addition, and curd disruption followed by repressing were studied. Here, disruption was not a chemical disruption, rather a physical disruption of protein curds. Pasteurization alone led to increased uptake of water and nonviable tofus. Disrupted samples became firmer with pasteurization. Texture profile analysis indicated that disruption followed by pasteurization improved hardness from approximately 175 g force from the control, to approximately 325 g force for disrupted + pasteurizated samples without fat addition. A similar trend was observed for samples with fat added, where hardness increased from approximately 50 g force to approximately 75 g force. Fourier‐transform infrared spectroscopy of the amide I region showed that an increase of β‐sheet structures led to increased hardness. The shifts in β‐sheet structures followed the same trends as surface hydrophobicity. Surface hydrophobicity decreased with pasteurization and increased with disruption. Molecular weight analysis showed that shear (from disruption) and heat separately degraded the proteins into smaller polypeptides exposing hydrophobic interiors. Changes to biochemical parameters, such as protein secondary structure and exposure of protein hydrophobic regions, allowed for tofu to be made from yellow field peas.Practical ApplicationThis study provides critical information and a means to produce pea‐based soy‐free tofu.

Published: November 2019

AbstractThe effects of four different extraction methods (Folch, Soxhlet, two‐step, and enzyme‐assisted aqueous extraction) on the yields, lipid class, fatty acids (FAs) composition, minor components (including carotenoid, cholesterol), and thiobarbituric acid reactive substances values of lipids in the hepatopancreas of Chinese mitten crab (Eriocheir sinensis) were investigated. The C16:0, C18:1, and C18:2 were identified to be the dominant FAs in crab lipids, and the FAs were present in the form of triglycerides. The Soxhlet and enzyme‐assisted extraction were more suitable for crab lipids extraction, showing higher extraction rates and oxidative stability. Especially, the lipid extracted by enzyme‐assisted extraction has high carotenoids content. The components of crab lipids extracted by enzyme‐assisted aqueous extraction were further identified using untargeted metabolomics methods. The polyunsaturated fatty acid, sterols, amino acids, products of lipid β‐oxidation and ATP degradation, phosphatidyl ethanolamine, and astaxanthin were founded in crab oil.Practical ApplicationThe Chinese mitten crab (Eriocheir sinensis) is a popular aquatic food in China. The hepatopancreas is the major lipid storage organ of crab, and the distinctive flavor of crab is mainly from it. To compare the different extraction methods on yield, composition and properties of crab lipids can be helpful for lipids production from crab hepatopancreas. Meanwhile, the crab hepatopancreas lipids are rich in polyunsaturated fatty acids and astaxanthin, and have potential to be as a functional component and a crab flavor additive in food industry.
Possible Sugar and Calorie Reduction by Visual Cues: A Case of Syrup Added to Brewed Coffee

Published: November 2019

AbstractVisual cues have been reported to influence taste and flavor perceptions. The objectives of this study were to evaluate the impact of visual cues (color and viscosity) of syrups on expected sweetness and bitterness perception (Study I), and on sweetness perception and sweetness liking of brewed coffee after syrup had been added, and the amount of syrups to be added to brewed coffee (Study II). For Study I, the visual stimuli were developed by varying viscosity (80, 800, and 8000 cP) and yellow index (YI) (0.04, 0.08, 0.16, and 0.32), resulting in 12 syrups with 20 degrees Brix. Visual observations indicated greater expected sweetness perceptions of syrups when YI and viscosity were increased. However, YI, but not viscosity, affected expected bitterness perceptions. Increasing YI raised the frequency (%) of “too sweet” perceptions of syrups on a JAR scale. For Study II, only four syrups (LC1, LC2, HC1, HC2; L = viscosity, 80 cP, H = 8,000 cP; C1 = YI 0.04, C2 = YI 0.32) were studied. The visual perception affected consumers’ behaviors concerning the amount of syrup added to brewed coffee. Consumers added the greatest volume of syrups with the lowest viscosity and YI (LC1), while the lowest volume of syrups with the highest viscosity and YI (HC2). There were no significant differences in sweetness liking of brewed coffees added with LC1, LC2, and/or HC1 syrups. This study indicated that visual cues could potentially intensify the perceived sweetness of syrups, and reduced the volume of syrup added to brewed coffee and consequently calories consumed.Practical ApplicationSensory visual cues associated with a syrup can be used to reduce the volume consumed and thereby promote reduced consumption of calories while maintaining sensory acceptability. Increasing a syrup's viscosity and yellow/brown color intensity enhanced the expectation of sweetness and resulted in less volume of syrup added to brewed coffee. This research demonstrated that the impact of visual cues not only influenced expectation and sensory acceptability but also impacted the cognitive process of eating. This strategy could provide a way to promote a sustainable reduction in sugar and, hence, calorie consumption without compromising sensory liking.

Published: November 2019

AbstractIn recent years, increasing evidence has accumulated supporting the health benefits of extra virgin olive oil (EVOO). Previous studies showed that EVOO supplementation improves Alzheimer's disease (AD)‐like amyloidotic phenotype of transgenic mice. However, while much attention has been focused on EVOO‐mediated modulation of Aβ processing, its direct influence on tau metabolism in vivo and synaptic function is still poorly characterized. In this study, we investigated the effect of chronic supplementation of EVOO on the phenotype of a relevant mouse model of tauopathy, human transgenic tau mice (hTau). Starting at 6 months of age, hTau mice were fed chow diet supplemented with EVOO or vehicle for additional 6 months, and then the effect on their phenotype was assessed. At the end of the treatment, compared with control mice receiving EVOO displayed improved memory and cognition which was associated with increased basal synaptic activity and short‐term plasticity. This effect was accompanied by an upregulation of complexin 1, a key presynaptic protein. Moreover, EVOO treatment resulted in a significant reduction of tau oligomers and phosphorylated tau at specific epitopes. Our findings demonstrate that EVOO directly improves synaptic activity, short‐term plasticity, and memory while decreasing tau neuropathology in the hTau mice. These results strengthen the healthy benefits of EVOO and further support the therapeutic potential of this natural product not only for AD but also for primary tauopathies.
