Which food prices were more vulnerable to the COVID-19 blockade regulations in China? Comparison between perishable and storable vegetables
Authors: Wang Yupeng , Shimokawa Satoru 
Published: January 2022

PurposeThis paper aims to investigate how differently the COVID-19 blockade regulations influence the prices of perishable and storable foods. The authors focus on the cases of the 2020 blockade at Hubei province and the 2021 blockade at Shijiazhuang city in China, and the authors examine how the blockade influenced the prices of Chinese cabbages (perishable) and potatoes (storable) within and around the blockade area.Design/methodology/approachThe paper employs the fixed effects model, the panel VAR (PVAR) model, and the spatial dynamic panel (SPD) model to estimate the impacts of the blockade on the food prices. It constructs the unique data set of 3-day average prices of Chinese cabbages and potatoes at main wholesale markets in China during the two urban blockade periods from January 1 to April 8 in 2020 and from January 1 to March 1 in 2021.FindingsThe results from the SPD models indicate that the price of Chinese cabbages was more vulnerable and increased by 7.1–9.8% due to the two blockades while the price of potatoes increased by 1.2–6.1%. The blockades also significantly influenced the prices in the areas adjacent to the blockade area. The SPD results demonstrate that the impacts of the blockades would be overestimated if the spatial dependence is not controlled for in the fixed effects model and the PVAR model.Research limitations/implicationsBecause the research focuses on the cases in China, the results may lack generalizability. Further research for other countries is encouraged.Originality/valueThis paper demonstrates the importance of considering food types and spatial dependence in examining the impact of the COVID-19 blockades on food prices.

Authors: Khin Sabai , Kee Daisy Mui Hung 
Published: January 2022

PurposeThe digital transformation towards Industry 4.0 (I4.0) has become imperative for manufacturers, as it makes them more flexible, agile and responsive to customers. This study aims to identify the factors influencing the manufacturing firms’ decision to adopt I4.0 and develop a triadic conceptual model that explains this phenomenon.Design/methodology/approachThis study used a qualitative exploratory study design based on multiple case studies (n = 15) from the manufacturing industry in Malaysia by conducting face-to-face interviews. The data were analysed using NVivo. The conceptual model was developed based on grounded theory and deductive thematic analysis.FindingsResults demonstrate that driving, facilitating and impeding factors play influential roles in a firms’ decision-making to adopt I4.0. The major driving factors identified are expected benefits, market opportunities, labour problem, customer requirements, competition and quality image. Furthermore, resources, skills and support are identified as facilitating factors and getting the right people, lack of funding, lack of knowledge, technical challenges, training the operators and changing the mindset of operators to accept new digital technologies are identified as impeding factors.Research limitations/implicationsDue to its qualitative design and limited sample size, the findings of this study need to be supplemented by quantitative studies for enhanced generalizability of the proposed model.Practical implicationsKnowledge of the I4.0 decision factors identified would help manufacturers in their decision to invest in I4.0, as they can be applied to balancing advantages and disadvantages, understanding benefits, identifying required skills and support and which challenges to expect. For policymakers, our findings identify important aspects of the ecosystem in need of improvement and how manufacturers can be motivated to adopt I4.0.Originality/valueThis study lays the theoretical groundwork for an alternative approach for conceptualizing I4.0 adoption beyond UTAUT (Unified Theory of Acceptance and Use of Technology). Integrating positive and negative factors enriches the understanding of decision-making factors for I4.0 adoption.

Purpose
Some kinds of foods, by producing an effect like addiction, may trigger overeating. This paper aims to investigate whether excessive chocolate consumption and hunger cause food addiction.

Design/methodology/approach
Food cravings questionnaire-trait-reduced (FCQ-T-r), food cravings questionnaire-state (FCQ-S) and eating attitude test-26 (EAT-26) scales were used. The relation between chocolate addiction, anthropometric measurements, demographic characteristics, eating behavior of the people were analyzed. The study was conducted on 864 individuals between 17 and 64 years old (men = 327, women = 537).

Findings
As the body mass index (BMI) of the individuals increased, chocolate craving, chocolate hunger, thought of eating chocolate, lack of control of chocolate increased. Also, significant correlations were determined with BMI, respectively, (r = 0.39; r = 0.32; r = 0.33; r = 0.29; p < 0.001). The lack of control overeating chocolate, craving for chocolate was found to be higher in female participants than in male participants. It was seen that craving for chocolate decreases (r = −0.17; p < 0.001) with increasing age; this was more apparent in male participants compared to female participants. Besides, significant correlation was found (r = 0.76, p < 0.05) between the EAT-26, the craving to eat chocolate in this study. It was seen that individual, who were excessively eager to consume chocolate, exhibited abnormal eating behavior (29.50 ± 12.09). This showed that there is a positive relation (r = 0.08, p < 0.001) between food addiction, eating attitude disorder.

Originality/value
Food craving increases the consumption of food, especially chocolate, sugar, with high carbohydrate content and energy. This can lead to overeating and being overweight.
Warehouse development and town planning policies in the UK
Authors: Jones Peter 
Published: January 2022

PurposeThis paper offers a review of national and local planning policies towards warehouse development within the UK.Design/methodology/approachThe first sections of the paper provide a description of the simple method of enquiry and sources of information used in the paper, outlines of the main factors driving the demand for warehousing space in the UK, and of the nature, scale and operation of modern warehouses, and a short review into the limited literature published to date, on town planning and on how it has influenced warehouse development. This is followed by an examination of some of the planning issues associated with warehouse development, two mini-case studies of how these issues are perceived and played out, a discussion of some of the issues raised in this examination and the mini-case studies.FindingsTown planning policies were traditionally seen as a restraint on the development of warehousing but while current national and local planning policies make little explicit reference to warehousing, they have often been cited in support of new warehouse development because such policies emphasise the importance of supporting economic growth and fostering the conditions in which businesses can invest and expand.Research limitations/implicationsThe paper has a number of limitations, not least that its source material is drawn from the Internet, and in that no primary data were collected from warehouse developers, warehouse operators, local planning officers or local authority councillors, and that the geographical coverage was limited.Originality/valueThe paper offers an accessible review of the current town planning issues associated with warehouse development in the UK.
How and when does humble leadership enhance newcomer well-being
Authors: Kang Fei , Li Jiyu , Hua Yuanyuan 
Published: January 2022

PurposeMany studies have examined the positive outcomes of humble leadership for employees. However, its impact on newcomers' well-being has been rarely investigated. In this paper, based on affective events theory and the broaden-and-build theory of positive emotions, the authors proposed a moderated mediation model to explore the effect of humble leadership on newcomer well-being. In the model, we identified newcomers' pride as a mediating variable and newcomers' proactive personality as a moderating variable.Design/methodology/approachThe data were from a two-wave sample containing 213 newcomers. The hypothesized model was tested using partial least squares structural equational modeling.FindingsThe results demonstrated that humble leadership was positively related to newcomers' well-being, and newcomers' pride medicated this relationship. Additionally, newcomers' proactive personality moderated the relationship between humble leadership and newcomers' pride.Research limitations/implicationsThe authors adopted a cross-sectional research design, rendering it difficult to derive causal relationships between variables. In addition, all data were from self-reports of newcomers which would suffer from common method variance.Originality/valueThis research examined the role of humble leadership in promoting newcomers' pride and well-being.
Learning from the biology of evolution: exaptation as a design strategy for future cities
Authors: Melis Alessandro , Lara-Hernandez Jose Antonio , Melis Barbora 
Published: January 2022

PurposeThis paper highlights the importance of transdisciplinary studies in times of crisis. In the first part, the study shows the benefits of the introduction of literature on biology to better understand the evolutionary dynamics of architecture.Design/methodology/approachThe focus of the research concerns architectural exaptation. In biology, exaptation is a functional shift of a structure that already had a prior but different function. We will also learn that, in biology, all creative systems are redundant and involve variability and diversity.FindingsAs a conclusion, through the comparison between biology and architecture, we will, therefore, try to build an architectural taxonomy that demonstrates how indeterminism is not a subcategory of design. Instead, design paradigms in which redundancy and variable diversity of structures reflect functionalism constitute an equivalent and essential complement with respect to design determinism.Originality/valueIt demonstrates how architectural exaptation, intended as an indeterministic and radical mode of design, can contribute to overcoming the current global crisis because structural redundancy is frequently functional, mostly in ever-changing and unstable environments. For instance, the failure of a planned function of a city can be an opportunity to re-use a structure designed for an obsolete function to respond to unexpected constraints.

Authors: Santos Margarida Custódio , Veiga Célia , Santos José António C. , Águas Paulo 
Published: January 2022

PurposeThis study sought to assess the extent to which tourism research has considered sustainability as a success factor for tourism destinations. It also aims to identify the relevance of the economic, environmental and socio-cultural dimensions of sustainability for tourist destination success, identify gaps in the literature and draw theoretical and practical implications and make recommendations.Design/methodology/approachThe research methodology consists of a systematic literature review on sustainability as a success factor for tourism destinations.FindingsResearch interest in the topic is recent and mostly focused on environmental sustainability. Developing a sustainable tourism policy and performing adequate destination management are crucial for tourism destination success. It is also acknowledged that perceiving a destination as sustainable has a significant positive impact on tourists' experiences, purchasing behaviour and loyalty.Originality/valueThis study's value arises from the fact that, to the best of the authors’ knowledge, no systematic literature review was yet been performed on the topic of sustainability as a success factor for tourism destinations.
Basic reproduction numbers of three strains of mouse hepatitis viruses in mice
Authors: Nakayama Masataka , Kyuwa Shigeru 
Published: January 2022

AbstractMouse hepatitis virus (MHV) is a murine coronavirus and one of the most important pathogens in laboratory mice. Although various strains of MHV have been isolated, they are generally excreted in the feces and transmitted oronasally via aerosols and contaminated bedding. In this study, we attempted to determine the basic reproduction numbers (R0) of three strains of MHV to improve our understanding of MHV infections in mice. Five‐week‐old female C57BL/6J mice were inoculated intranasally with either the Y, NuU, or JHM variant strain of MHV and housed with two naïve mice. After 4 weeks, the presence or absence of anti‐MHV antibody in the mice was determined by ELISA. We also examined the distribution of MHV in the organs of Y, NuU, or JHM variant‐infected mice. Our data suggest that the transmissibility of MHV is correlated with viral growth in the gastrointestinal tract of infected mice. To the best of our knowledge, this is the first report to address the basic reproduction numbers among pathogens in laboratory animals.
Turnover in floral composition explains species diversity and temporal stability in the nectar supply of urban residential gardens

Published: January 2022

Abstract

Residential gardens are a valuable habitat for insect pollinators worldwide, but differences in individual gardening practices substantially affect their floral composition. It is important to understand how the floral resource supply of gardens varies in both space and time so we can develop evidence‐based management recommendations to support pollinator conservation in towns and cities.

We surveyed 59 residential gardens in the city of Bristol, UK, at monthly intervals from March to October. For each of 472 garden surveys, we combined floral abundances with nectar sugar data to quantify the nectar production of each garden, investigating the magnitude, temporal stability, and diversity and composition of garden nectar supplies.

We found that individual gardens differ markedly in the quantity of nectar sugar they supply (from 2 to 1,662 g), and nectar production is higher in more affluent neighbourhoods, but not in larger gardens. Nectar supply peaks in July (mid‐summer), when more plant taxa are in flower, but temporal patterns vary among individual gardens. At larger spatial scales, temporal variability averages out through the portfolio effect, meaning insect pollinators foraging across many gardens in urban landscapes have access to a relatively stable and continuous supply of nectar through the year.

Turnover in species composition among gardens leads to an extremely high overall plant richness, with 636 taxa recorded flowering. The nectar supply is dominated by non‐natives, which provide 91% of all nectar sugar, while shrubs are the main plant life form contributing to nectar production (58%). Two‐thirds of nectar sugar is only available to relatively specialised pollinators, leaving just one‐third that is accessible to all.

Synthesis and applications. By measuring nectar supply in residential gardens, our study demonstrates that pollinator‐friendly management, affecting garden quality, is more important than the size of a garden, giving every gardener an opportunity to contribute to pollinator conservation in urban areas. For gardeners interested in increasing the value of their land to foraging pollinators, we recommend planting nectar‐rich shrubs with complementary flowering periods and prioritising flowers with an open structure in late summer and autumn.
Analysis of methylphenidate, ethylphenidate, lisdexamfetamine, and amphetamine in oral fluid by liquid chromatography‐tandem mass spectrometry
Authors: Smith Christina R. , Swortwood Madeleine J. 
Published: January 2022

AbstractOral fluid is an alternative matrix that has proven to be useful for the detection of drugs. Oral fluid is easy to collect, noninvasive, and may indicate recent drug use. There are limited methods available that analyze cognitive stimulants in oral fluid. Cognitive stimulants are used to treat attention‐deficit/hyperactivity disorder (ADHD), a neurological disorder that emerges from lack of dopamine in the brain. To combat this disorder, medications inhibit dopamine and norepinephrine reuptake by blocking transporters in the brain. Though commonly diagnosed in children, ADHD may extend beyond adolescence and abuse of medications in college students is not uncommon. The goal of this study was to develop and validate a quantitative method for methylphenidate, ethylphenidate, lisdexamfetamine, and amphetamine in oral fluid using liquid chromatography‐tandem mass spectrometry (LC‐MS/MS). Analytes were isolated by solid‐phase extraction and analyzed on an Agilent 1290 Infinity II Liquid Chromatograph coupled to an Agilent 6470 Triple Quadrupole Mass Spectrometer. The linear range was 0.5–100 ng/ml (except lisdexamfetamine at 5–500 ng/ml). Bias and between‐run precision were acceptable (±11.0% bias and ±12.2%CV). No interferences or carryover were observed and dilution integrity was sustained. This validated method was applied to four authentic oral fluid samples collected with Quantisal® devices from college students. Lisdexamfetamine was quantified in one sample at 5.8 ng/ml while amphetamine was quantified in all four samples at 6.0–78.8 ng/ml. This is the first known quantitative method in oral fluid that includes these analytes using LC‐MS/MS and may give rise to interpretive value in a forensic toxicology setting.

Published: January 2022

AbstractAimTo examine prevalence of mental health conditions and receipt of mental health care (MHC) by illicit lysergic acid diethylamide (LSD) use status (past‐year; lifetime without‐past‐year; never) among young adults.DesignCross‐sectional, annual survey data from 2015 to 2019 National Surveys on Drug Use and Health (NSDUH).SettingUnited States.ParticipantsA total of 69 916 NSDUH participants ages 18 to 25.MeasurementsOutcomes included past‐year serious psychological distress (SPD), suicidal ideation, Diagnostic and Statistical Manual of Mental Disorders (DSM)‐IV major depressive episode (MDE), any mental illness, serious mental illness, receipt of mental health care (MHC, inpatient/outpatient or receipt of prescription medications), and number of days of being unable to work or attend normal activities because of mental health conditions.FindingsMultivariable analyses found that compared with those who never used illicit LSD, adults with past‐year illicit LSD use had greater risk of suicidal ideation (adjusted risk ratio [ARR] = 1.2, 95% CI = 1.06–1.41), SPD (ARR = 1.2, 95% CI = 1.04–1.28), MDE (ARR = 1.3, 95% CI = 1.17–1.52), and any/serious mental illness (ARRs = 1.2–1.3, 95% CI = 1.02–1.41) and reported missing more days because of mental health conditions (adjusted incidence rate ratio = 1.6, 95% CI = 1.31–1.86). Lifetime (without past‐year) use showed similar, although less consistent, associations. Compared with those never using illicit LSD, adults with past‐year use were less likely to receive prescription medications for MHC (ARR = 0.7, 95% CI = 0.60–0.84) and to receive overall MHC (ARR = 0.7, 95% CI= 0.64–0.84). Compared with those using in the past‐year, adults with lifetime (without past‐year) use were more likely to receive prescription medications for MHC (ARR = 1.2, 95% CI = 1.01–1.46) and receive overall MHC (ARR = 1.2, 95% CI = 1.03–1.45).ConclusionsYoung adults with past‐year illicit lysergic acid diethylamide use have elevated prevalence of mental health conditions and are less likely to receive prescription medications for mental health care and overall mental health care. Regardless of past‐year use status, young adults with lifetime illicit lysergic acid diethylamide use may benefit from mental illness prevention and interventions.

Published: January 2022

AbstractAimThe sodium/hydrogen exchanger 2 (NHE2) is an intestinal acid extruder with crypt‐predominant localization and unresolved physiological significance. Our aim was to decipher its role in colonic epithelial cell proliferation, differentiation and electrolyte transport.MethodsAlterations induced by NHE2‐deficiency were addressed in murine nhe2−/− and nhe2+/+ colonic crypts and colonoids, and NHE2‐knockdown and control Caco2Bbe cells using pH‐fluorometry, gene expression analysis and immunofluorescence.ResultspHi‐measurements along the colonic cryptal axis revealed significantly decreased intracellular pH (pHi) in the middle segment of nhe2−/− compared to nhe2+/+ crypts. Increased Nhe2 mRNA expression was detected in murine colonoids in the transiently amplifying/progenitor cell stage (TA/PE). Lack of Nhe2 altered the differentiation programme of colonic epithelial cells with reduced expression of absorptive lineage markers alkaline phosphatase (iAlp), Slc26a3 and transcription factor hairy and enhancer‐of‐split 1 (Hes1), but increased expression of secretory lineage markers Mucin 2, trefoil factor 3 (Tff3), enteroendocrine marker chromogranin A and murine atonal homolog 1 (Math1). Enterocyte differentiation was found to be pHi dependent with acidic pHi reducing, and alkaline pHi stimulating the expression of enterocyte differentiation markers in Caco2Bbe cells. A thicker mucus layer, longer crypts and an expanded brush border membrane zone of sodium/hydrogen exchanger 3 (NHE3) abundance may explain the lack of inflammation and the normal fluid absorptive rate in nhe2−/− colon.ConclusionsThe results suggest that NHE2 expression is activated when colonocytes emerge from the stem cell niche. Its activity increases progenitor cell pHi and thereby supports absorptive enterocyte differentiation.
Sectoral digital intensity and GDP growth after a large employment shock: A simple extrapolation exercise
Authors: Gallipoli Giovanni , Makridis Christos A. 
Published: January 2022

AbstractWe introduce a state‐dependent algorithm with minimal data requirements for predicting output dynamics as a function of employment across industries and locations. The method generalizes insights of Okun (1963) by leveraging measures of industry heterogeneity. We use the algorithm to examine gross domestic product (GDP) dynamics following the COVID‐19 pandemic of 2020, delivering informative projections of aggregate and sectoral output. Because the pandemic curtailed the ability to perform certain tasks at work, our application examines whether greater reliance on digital technologies can mediate employment and productivity losses. We use industry‐level indices of digital task intensity and ability to work from home, together with publicly available data on employment and GDP for Canada, to document that: (i) employment responses after the shock's onset are milder in digitally intensive sectors and (ii) conditional on the size of employment changes, GDP responses are less extreme in digitally intensive sectors. Our projections indicate a return to pre‐crisis aggregate output within eight quarters of the initial shock with significant heterogeneity in recovery patterns across sectors.
