Price or quality? Consumers' preferences and willingness to pay (WTP) for online food delivery services in the COVID-19 era
Authors: Singh Satender Pal , Dash Bishnu Prasad , Sachan Amit , Adhikari Arnab 
Published: August 2023

PurposeThis article investigates the impact of the COVID-19 pandemic on the consumer preference for the attributes of online food delivery (OFD) services in India. It also shows how the order size influences the consumer's willingness to pay (WTP) for the attributes of OFD services.Design/methodology/approachThis work incorporates a conjoint analysis-based approach to determine the consumer preference for the attributes of OFDs such as price, delivery time, restaurant rating and packing quality during the COVID-19 pandemic. The fractional factorial design is applied for the data collection. The relative importance of the attributes and the part-worth utility of the attributes' levels have been determined. Further, the utility associated with the attributes' levels is used to find the consumer's WTP for different attributes.FindingsThe COVID-19 pandemic has changed consumer preference from price to food and packing quality in India. When the order is small, consumers exhibit a higher preference to the delivery time than packing quality. In contrast, consumers show a higher preference to packing quality than delivery time with the increase in order size. The consumer's WTP attains the highest level in case of food quality, followed by convenience and packing quality. The WTP for the attributes rises with the increase in order size.Practical implicationsThe insights highlight the need for the online food delivery industry to redesign the business framework in the post-pandemic era. The hygiene and safety measures maintained by the consumers during the pandemic have significantly changed their purchasing behaviour, raising their preference for service quality (food and packing quality) of the OFD services apart from price.Originality/valueThis work determines the consumers' utility for each attribute level of OFDs, along with their relative importance. Moreover, this study contributes to the existing literature by exhibiting the impact of the COVID-19 pandemic on the consumer preference and order size on consumer's WTP for the attributes.
Management strategies can buffer the effect of mass mortality in early life stages of fish

Abstract

Mass mortality (MM) events affecting early life stages of fish can have strong and long‐term consequences for population abundance and demography as well as the economic activity supported by exploited stocks. Adaptive fishery management may help mitigate economic impacts and ensure sustainable resource use following a MM event.

Using a state‐space life cycle model, we simulated ‘what‐if’ scenarios of MM on Northeast Arctic cod (Gadus morhua) eggs and larvae. We compared the expected catches, total stock biomass (TSB), and interannual variability in catches over a period of 10 years after the simulated disturbance. We further evaluated a range of management mitigation strategies, namely reductions in fishing mortality of varying duration (1–10 years) and intensity (no fishing reduction to full ban).

A large range of reductions in fishing led to an increase in expected catches over 10 years compared to no reductions, especially when applied immediately after the perturbation and when the cod population was characterized by a high mean age and high TSB. Severe fishing reductions can increase catches substantially but are associated with high interannual variability. Fishing reductions of moderate intensity applied between 1 and 4 years would allow to increase catches with only a slight increase in interannual variability.

Our findings demonstrate the potential benefits of an adaptive approach to fisheries management and highlight that mitigation actions may ensure the sustainable exploitation of fish stocks in the wake of unexpected disturbances.

Synthesis and application. Mass mortality events during early life stages of fish can potentially have substantial and long‐term effects on the population. Mitigation is more efficient when the affected population has a diverse age structure and when the mitigation strategy is applied immediately after the perturbation. Severe reduction in fishing mortality is an efficient measure to increase the expected average catch but is associated with high interannual variability. Fishing reduction of moderate intensity applied during 1–4 years after the event also increases the expected average catch with only slightly higher interannual variability in catches.
Impact of natural resources, trade openness, and economic growth on CO2 emissions in oil‐exporting countries: A panel autoregressive distributed lag analysis

Published: August 2023

AbstractThis study explores the impact of natural resource exploitation, trade openness, and economic growth on carbon emissions in a sample of oil‐exporting nations for the period 1971–2014. To examine this relationship, we used the panel autoregressive distributed lag model and a set of econometric techniques accounting for cross‐sectional dependence. Our results indicate that the exploitation of natural resources and trade openness have a long‐term negative impact on environmental quality. Furthermore, our analysis confirms the validity of the Kuznets Environmental Curve for oil‐exporting countries. An assessment of causality reveals a bidirectional link between natural resources, economic growth, and CO2 emissions, as well as a unidirectional link between trade openness and CO2 emissions. In the light of our findings, appropriate policies could include the imposition of more stringent regulations on the exploitation of natural resources, the application of taxes on carbon emissions, and the promotion of clean and renewable technologies. Greater international cooperation is also needed to address these environmental issues on a global scale.
Conceptualising the nexus between macro‐level ‘turbulence’ and the worker experience

Published: August 2023

AbstractIn this article, we introduce the special issue on conceptualising the nexus between macro‐level ‘turbulence’ and the worker experience. We discuss ‘turbulence’ as economic, political, social, technological, and environmental crises occurring in the macro‐environment and affecting the world of work. We argue that human resource management plays a critical role in supporting not only the organisation, but also workers, to navigate through macro‐level events. Based on the contributions included in this Special Issue, we suggest a novel framework that situates and expands the role of the Human Resources (HR) function in contemporary organisations by proposing a new role, the Proactive Carer. We argue that the debates around the role of HR and HR professionals have so far been too narrow and internally focused. It is time to expand this role to be externally facing, proactively monitoring the macro‐environment for significant events, anticipating any significant changes for workers, and designing interventions to minimise any negative impact. We conclude by highlighting avenues for future research.

AbstractAimAn estimated 88% of rheumatoid arthritis (RA) patients experience various degrees of cervical spine involvement. The excessive movement of the atlantoaxial joint, which connects the occiput to the upper cervical spine, results in atlantoaxial instability (AAI). AAI stabilization is usually achieved by C1 lateral mass‐to‐C2 pedicle screw‐rod fixation (LC1–PC2 fixation), which is technically challenging in RA patients who often show destructive changes in anatomical structures. This study aimed to analyze the clinical results and operative experiences of C1–C2 surgery, with emphasis on the advancement of image‐guided surgery and augmented reality (AR) assisted navigation.MethodsWe presented our two decades of experience in the surgical management of AAI from April 2004 to November 2022.ResultsWe have performed surgery on 67 patients with AAI, including 21 traumatic odontoid fractures, 20 degenerative osteoarthritis, 11 inflammatory diseases of RA, 5 congenital anomalies of the os odontoideum, 2 unknown etiologies, 2 movement disorders, 2 previous implant failures, 2 osteomyelitis, 1 ankylosing spondylitis, and 1 tumor. Beginning in 2007, we performed LC1–PC2 fixation under C‐arm fluoroscopy. As part of the progress in spinal surgery, since 2011 we used surgical navigation from presurgical planning to intraoperative navigation, using the preoperative computed tomography (CT) ‐based image‐guided BrainLab navigation system. In 2021, we began using intraoperative CT scan and microscope‐based AR navigation.ConclusionThe technical complexities of C1–C2 surgery can be mitigated by CT‐based image‐guided surgery and microscope‐based AR navigation, to improve accuracy in screw placement and overall clinical outcomes, particularly in RA patients with AAI.
Fair and inclusive markets: Why dynamism matters
Authors: Cherif Reda , Hasanov Fuad , Aghion Philippe 
Published: August 2023

AbstractWe argue that the economies that achieved inclusive growth, or high sustained and broad‐based growth while keeping a lid on the increase in market income inequality, are characterised by dynamism—a drive towards the acquisition of new capabilities in sophisticated products and processes. What a country produces and how much it competes domestically and internationally are important for achieving fair and inclusive markets. We show empirical evidence that dynamism, as measured by export sophistication, reduces market income inequality and poverty while increasing a broad concept of welfare. We explore policy options to steer industrial and market structures towards raising dynamism, thus providing growth opportunities for both workers and firms.
Decoding the star system: Twitter and its impact on journalism in the global South

Published: August 2023

AbstractChanges brought about by the digitalisation of journalism in the global South have implications for the role that the press plays in politics and governance, particularly in terms of giving a voice to those on the margins. This paper presents original evidence from India to consider how Twitter is reshaping the hierarchies within journalism and how it contributes to a ‘star system’ in Indian media institutions whereby national journalists as well as celebrities have gained more influence over journalists working in the regional press. Drawing on public profiles of over 50 journalists, while anonymizing individual identities, we computationally map their follower‐following networks on Twitter and analyse the resulting structures to show how they intensify the historical divide between the Delhi‐based legacy institutions and the vernacular language media. Besides using network graphs, we develop topic models of the biographies of journalists from different social cohorts and find a divergence in the way celebrity‐seeking journalists use Twitter more effectively than those working in the regional press, with the latter not able to match the strategic use of the network for personal branding by the former cohort. We conclude that this divergence can also be contributing towards a star system like structure of journalism online with readership and influence flowing to those at the centre. We conclude with recommendations for editors, journalists as well as technology developers on how to avoid such outcomes.

AbstractBackground and aimsAlthough multiracial people comprise the fastest growing population in the United States, multiracial youth are nearly invisible in alcohol research. This meta‐analysis synthesized the youth alcohol literature to estimate the magnitude of difference in alcohol use as a function of multiracial status.Design and MeasurementsEmpirical studies reporting multiracial and monoracial comparisons in youth (aged 10–24 years) alcohol use were identified through a systematic literature search. A random‐effects meta‐analysis was conducted using 85 effect sizes extracted from 16 studies assessing life‐time, past‐year, past‐month and binge alcohol use.Setting and ParticipantsA total of n=1 555 635 youth were assessed in the United States.FindingsMultiracial youth are suggested to be more likely to endorse life‐time alcohol use than Asian youth [number of studies (k) = 3; odds ratio (OR) = 1.81, 95% confidence interval (CI) = 1.01, 3.24; p = 0.04], with significant between‐study heterogeneity (Q = 8.42; p < 0.001; I2 = 76%) in effect size comparisons. Multiracial youth are suggested to be more likely to endorse past‐month alcohol use than Black (k = 6; OR = 1.54, 95% CI = 1.38, 1.71; p < 0.001) and Asian (k = 4; OR = 2.09, 95% CI = 1.52, 2.88; p < 0.001) youth, but less likely than White (k = 6; OR = 0.87, 95% CI = 0.84, 0.91; p < 0.001) youth, with significant between‐study heterogeneity for Black youth (Q = 11.94; p = 0.03; I2 = 58%) in effect size comparisons. Lastly, multiracial youth are suggested to be more likely to endorse binge alcohol use than Black (k = 4; OR = 1.98, 95% CI = 1.62, 2.44; p < 0.001) and Asian (k = 4; OR = 2.82, 95% CI = 2.28, 3.48; p < 0.001) youth, but less likely than White (k = 5; OR = 0.75, 95% CI = 0.70, 0.81; p < 0.001) and American Indian/Alaska Native (k = 3; OR = 0.78, 95% CI = 0.71, 0.85; p < 0.001) youth, with significant between‐study heterogeneity among Black (Q = 23.99; p < 0.001; I2 = 87%) and Asian (Q = 17.76; p < 0.001; I2 = 83%) youth in effect size comparisons.ConclusionsIn the United States, multiracial youth report distinct alcohol use patterns compared with monoracial youth and may be at elevated alcohol use risk compared with Black and Asian youth.

Published: August 2023

AbstractInsects provide valuable ecosystem services to agriculture, but their populations are often lower in these areas.We established floral strips on the edges of eight organic and seven conventional crop fields in southern Manitoba. We then compared the capture rates of ground beetles, syrphid flies and bees in floral strips; control (unmodified) field edges; nearby semi‐natural sites; and within the strip and control fields at six distances away from field borders (5–150 m). The effects of farm management and landscape context on insect abundance, diversity and associated species traits were investigated.Capture rates of bees and beetles were significantly higher within the floral strips than the control treatment. However, capture rates of syrphids were significantly higher in the control. Beetles and bees responded positively to blooming forb cover and edge density (0.5 km), whereas syrphids responded positively to non‐rewarding agriculture and negatively to the semi‐natural areas (1 km). We found no significant difference in insect abundance or diversity between organic and conventional management types, and no differences in insect abundances within the fields were detected. No significant associations between insect traits and landscape variables were identified.These results show that floral strips are effective at attracting ground beetles and bees shortly after establishment, but these communities are functionally similar to those present in control fields. Longitudinal studies are needed to determine whether populations continue to increase over time and become more functionally diverse in fields with floral strips.

AbstractClassic galactosemia (OMIM#230400) is an autosomal recessive inborn error of carbohydrate metabolism caused by a deficiency of the galactose‐1‐phosphate‐uridyl‐transferase enzyme encoded by the GALT gene. Even though a galactose‐restricted diet efficiently resolves the acute complications, it is insufficient to prevent long‐term complications regarding speech defects, intellectual functioning, premature ovarian failure, cataract, hepatomegaly, dysarthria, ataxia, and tremor. Seventy‐seven patients who were genetically diagnosed with classic galactosemia were included in this cohort. Identified novel variants were classified based on their predicted effect on the GALT function. Further, potential genotype–phenotype correlations were investigated via statistical analysis. In total, 18 different sequence variants were identified, including four novels (c.200delG/p.(Arg67Profs*19), c.533T>G/ p.(Met178Arg), c.708_709delGT/p.(Ser236Argfs*30), c.467C>A/p.(Ser156*)). Jaundice was the most common short‐term finding with 80% (61/77). Even with early diagnosis, intellectual disability is encountered with 36% (27/74) of the long‐term complications. Patients with biallelic missense variants have a significantly higher prevalence of cataracts (OR: 17.9). Longitudinal observations showed attenuation of cataracts and hepatomegaly. This study has shown the GALT variation spectrum of the Turkish population with a 30‐year retrospective cohort, submitting a significant contribution to the genotype/phenotype correlation in galactosemia. This study also highlights the cost‐effective importance of Sanger sequencing in the diagnosis of single‐gene metabolic diseases.

Published: August 2023

AbstractBackgroundEwing's family sarcoma (EFS) is an aggressive malignancy with a peak incidence in adolescents. Multimodal treatment involves surgery and/or radiotherapy, and chemotherapy typically with VDC/IE (vincristine, doxorubicin, and cyclophosphamide alternating with ifosfamide and etoposide). There is a paucity of data for the treatment of adults, with protocols extrapolated from the pediatric setting. This study aimed to assess patterns of care, chemotherapy tolerability across age groups, and outcomes from four Australian sarcoma centers.MethodsANZSA ACCORD sarcoma database and medical records were used to identify and collect data of patients aged ≥ 10 years with EFS who received VDC/IE between 2010 and 2020. Survival outcomes were analyzed based on chemotherapy received dose intensity (RDI). Clinical predictors of RDI were explored using logistic regression.ResultsOf 146 patients with EFS, 76 received VDC/IE. The majority had localized disease (65%). Seventy‐one percent completed scheduled chemotherapy, with some requiring dose reduction (29%), delay > 7 days (65%), or cycle omission (4%). Hematological toxicity was the main reason for dose reduction/delay. Fifty‐seven percent patients achieved an acceptable RDI ≥85%. Compared to those aged 10–19, the odds ratio for acceptable RDI aged 40–59 was 0.20 (95% CI 0.04−0.86, p = 0.04). RDI was an independent prognostic factor for overall survival, after accounting for age, gender, Ewing's type, primary site, and stage (adjusted HR 0.25 [95% CI 0.10−0.63], p = 0.004).ConclusionSurvival outcomes in EFS were associated with chemotherapy RDI. Older adults more commonly required dose reduction or early cessation of treatment due to toxicity. VDC/IE chemotherapy should be carefully tailored in adults > 40 years.

AbstractIntroductionThis study aims to investigate non‐invasive electrocardiography as a method for the detection of congenital heart disease (CHD) with the help of artificial intelligence.Material and methodsAn artificial neural network was trained for the identification of CHD using non‐invasively obtained fetal electrocardiograms. With the help of a Bayesian updating rule, multiple electrocardiographs were used to increase the algorithm's performance.ResultsUsing 122 measurements containing 65 healthy and 57 CHD cases, the accuracy, sensitivity, and specificity were found to be 71%, 63%, and 77%, respectively. The sensitivity was however 75% and 69% for CHD cases requiring an intervention in the neonatal period and first year of life, respectively. Furthermore, a positive effect of measurement length on the detection performance was observed, reaching optimal performance when using 14 electrocardiography segments (37.5 min) or more. A small negative trend between gestational age and accuracy was found.ConclusionsThe proposed method combining recent advances in obtaining non‐invasive fetal electrocardiography with artificial intelligence for the automatic detection of CHD achieved a detection rate of 63% for all CHD and 75% for critical CHD. This feasibility study shows that detection rates of CHD might improve by using electrocardiography‐based screening complementary to the standard ultrasound‐based screening. More research is required to improve performance and determine the benefits to clinical practice.

Published: August 2023

AbstractIntroductionData on loneliness among older adults in China during the COVID‐19 pandemic are still scarce. This study aimed to examine the prevalence of loneliness and identify its associated factors among older Chinese adults during the COVID‐19 pandemic.MethodsDuring the COVID‐19 pandemic, 1268 older Chinese adults (aged 50+ years) were recruited through snowball sampling. The Chinese version of the validated six‐item De Jong Gierveld Loneliness Scale was used to assess participants' recent feelings of loneliness, and a cut‐off score of two or more was used to indicate the presence of loneliness.ResultsLoneliness was experienced by 37.9% of the participants in recent days. Factors significantly associated with loneliness included male sex (vs. female, OR: 1.62, p < .001), an education level of middle school and below (vs. college and above, OR: 1.50, p = .007), residing in the COVID‐19 epicenter (vs. other provinces, OR: 1.48, p = .004), concern about contracting COVID‐19 (OR: 1.68, p = .001), poor knowledge of COVID‐19 (OR: 2.39, p = .012), and physical health problems (OR: 1.65, p < .001).DiscussionLoneliness is common among older Chinese adults amid the COVID‐19 pandemic. Targeted intervention programs may be more effective in reducing loneliness among older adults who are worried about contracting COVID‐19, have poor COVID‐19 knowledge, and experience physical health problems.
