Examining the nexus between food retailers certification and its impacts
Authors: Bannor Richard Kwasi , Amfo Bismark , Oppong-Kyeremeh Helena 
Published: April 2022

PurposeThe authors assessed the certification of street food retailers in Ghana in terms of awareness, training, willingness to be certified, determinants, agreement with certification requirements and impacts on performance.Design/methodology/approachPrimary data was sourced from 200 street food retailers. Descriptive statistics, Likert scale, mean comparison test, heteroskedastic probit, inverse-probability-weighted regression adjustment (IPWRA), inverse probability weights (IPW) and augmented inverse-probability weighting (AIPW) were applied.FindingsMost uncertified retailers were willing to be certified. Awareness about certification was high. Most of the certified retailers had been trained on certification, while most uncertified retailers had not been trained. Being a female, being educated, being a migrant vendor, possessing experience in retailing, training in certification, trust in the local certification process, the amount spent in preparing food and the number of customers are crucial variables that increase the probability of being certified among street food vendors. Street food retailers agreed to all the requirements for certification. Certification boosts the performance of street food retailers in terms of the number of customers and contracts received. Training on certification is recommended for street food retailers.Research limitations/implicationsThe limitation of this study is mainly due to the type of food retailers selected. Street food vending in Ghana is done among those who cook food for selling, those who sell processed products such as drinks and those who sell vegetables and other uncooked agriproducts. Meanwhile, the authors selected unorganised retailers who primarily cook local and regional dishes for sale in this study. Thus, the study did not include organised food retailers such as restaurants. Therefore, generalising the study results for street food vendors should be made with caution.Originality/valueSeveral studies have been conducted on street food retailing across the globe on knowledge of food-safety practices, risk practices, bacterial contamination of street retailing food, toxicological hazards of street foods and compliance with technical and hygienic requirements by street food retailers, among others. However, empirical studies on the certification/licensing of street food retailers and its impact have been given little attention. As a result, this study investigates the certification of street food retailers and its impacts on retailers' performance in Ghana.
Merging control strategies of connected and autonomous vehicles at freeway on-ramps: a comprehensive review
Authors: Zhu Jie , Easa Said , Gao Kun 
Published: April 2022

Purpose
On-ramp merging areas are typical bottlenecks in the freeway network since merging on-ramp vehicles may cause intensive disturbances on the mainline traffic flow and lead to various negative impacts on traffic efficiency and safety. The connected and autonomous vehicles (CAVs), with their capabilities of real-time communication and precise motion control, hold a great potential to facilitate ramp merging operation through enhanced coordination strategies. This paper aims to present a comprehensive review of the existing ramp merging strategies leveraging CAVs, focusing on the latest trends and developments in the research field.

Design/methodology/approach
The review comprehensively covers 44 papers recently published in leading transportation journals. Based on the application context, control strategies are categorized into three categories: merging into sing-lane freeways with total CAVs, merging into sing-lane freeways with mixed traffic flows and merging into multilane freeways.

Findings
Relevant literature is reviewed regarding the required technologies, control decision level, applied methods and impacts on traffic performance. More importantly, the authors identify the existing research gaps and provide insightful discussions on the potential and promising directions for future research based on the review, which facilitates further advancement in this research topic.

Originality/value
Many strategies based on the communication and automation capabilities of CAVs have been developed over the past decades, devoted to facilitating the merging/lane-changing maneuvers at freeway on-ramps. Despite the significant progress made, an up-to-date review covering these latest developments is missing to the authors’ best knowledge. This paper conducts a thorough review of the cooperation/coordination strategies that facilitate freeway on-ramp merging using CAVs, focusing on the latest developments in this field. Based on the review, the authors identify the existing research gaps in CAV ramp merging and discuss the potential and promising future research directions to address the gaps.

Exploring the knowledge structure of the relationship between value co-creation and customer satisfaction
Authors: Nájera-Sánchez Juan-José , Martinez-Cañas Ricardo , García-Haro María-Ángeles , Martínez-Ruiz María Pilar 
Published: April 2022

PurposeGiven the growing importance of the relationship between customer value co-creation and customer satisfaction, it is essential to assess the implications of this connection from both a managerial and an academic perspective. The literature on this link has grown enormously in recent years. However, there lacks an integrative framework to improve its understanding. Based on the use of bibliometric techniques, the purpose of this article is threefold: firstly, to shed light on the relationship's knowledge structure by identifying the main clusters of topics; secondly, to propose an integrative conceptual framework and finally, to identify future avenues of research.Design/methodology/approachThe authors analyze a database of 133 recent documents dealing with this pairing to address this gap. A bibliometric coupling methodology was used. Additionally, an in-depth analysis of centrality, density and citations for the different clusters identified in the last years was performed. The authors characterize each group in the knowledge map of the relationship.FindingsThis bibliometric analysis identified seven thematic clusters. Three of these, with a more transversal nature, have fostered the growth of this literature. The subsequent clusters used theoretical frameworks present in the first three clusters, adapting them to the specific circumstances analyzed, following different patterns of evolution. The authors present the behavior of the citations in each cluster over recent years, analyzing their intellectual base, trends and development potential.Originality/valueDerived from their findings, an integrative conceptual framework for explaining the knowledge structure of research in value co-creation and the customer satisfaction literature is proposed. The authors identify main topics by clusters and then detect research gaps and propose new research avenues for the future.
Elimination of the reserve requirement: impact on liquidity at community banks versus non-community banks
Authors: Fayman Alex , Chen Su-Jane , Mayes Timothy R. 
Published: April 2022

PurposeThe purpose of this paper is to better understand the differences between community and non-community banks (CBs and Non-CBs) in the US. As the former have been declining in numbers, previous literature shows inherent differences between the business models of CBs and Non-CBs. This study attempts to gauge whether the impact of the reserve elimination during the Covid pandemic affected all banks similarly or whether community banks showed a differentiated response.Design/methodology/approachOn March 26, 2020, the Federal Reserve, at the onset of the Covid pandemic, altered the depository institution reserve requirement for the first time since 1992. This significant change in policy led to the reserve requirement reduction from 10% to 0%. This study examines the impact of the 2020 reserve elimination on all community banks and non-community banks in the US and finds that although the level of cash to assets increased at both types of depository institutions post reserve elimination, the impact on liquidity-focused ratios was more pervasive at community banks in the first quarter post the regulatory shift. Among community banks, the largest depository institutions experienced the biggest balance sheet adjustments in the June 2020 quarter that followed the change in Federal Reserve’s policy. Further, the study finds that over two-quarters post reserve elimination, the non-community banks demonstrate a greater increase in balance sheet liquidity. Past literature shows that community banks tend to carry more liquidity than non-community banks and small community banks tend to carry more liquidity than their larger counterparts. These previous findings may provide some explanation for the different speed documented in this study at which various banks have reacted to the reserve elimination in 2020.FindingsThis research finds that community banks had a quicker response to the change in the reserve elimination, showing quick increases across liquidity ratios. The larger non-community banks tended to play catch up, increasing their liquidity in the subsequent quarter. The study also shows that the changes in liquidity were initially driven by the segment of large community banks.Originality/valueThis study looks at how the reserve elimination enacted by the Federal Reserve in March 2020 in response to the Covid pandemic affected community versus non-community banks. Currently, as far as the authors know, there are no other published papers that look at this issue.

Authors: Khudayarov Bakhtiyar , Turaev Fozilzhon 
Published: April 2022

PurposeThe purpose of this study is to create a mathematical model, a numerical algorithm and a computer program for studying the vibration of composite pipelines based on the theory of beams used in the oil and gas industry, agriculture and water management, housing and communal services and other areas.Design/methodology/approachA mathematical model of vibration of a viscoelastic pipeline based on the theory of beams with a pulsating fluid flowing through it was developed. Using the Bubnov-Galerkin method, based on the polynomial approximation of deflections, the problem is reduced to the study of systems of ordinary integro-differential equations, the solution of which is found by a numerical method. A computational algorithm was developed for solving problems of vibrations of composite pipelines conveying pulsating liquid.FindingsThe stability and amplitude-time characteristics of vibration of composite pipelines with a pulsating fluid flowing in it are studied for wide range of changes in the parameters of deformable systems and fluid flow. The critical velocities of fluid flow at which the viscoelastic pipe loses its rectilinear equilibrium shape are found. The effect of singularity in the kernels of heredity on the vibrations of structures with viscoelastic properties was numerically studied. It is shown that with an increase in the viscosity parameter of the pipeline material, the critical flow velocity decreases. It was determined that an increase in the value of the fluid pulsation frequency and the excitation coefficient leads to a decrease in the critical velocity of the fluid flow. It was established that an increase in the parameters of the Winkler foundation and the rigidity parameter of the continuous layer leads to an increase in the critical flow velocity.Originality/valueThe study of the vibration of pipelines made of composite materials is of great theoretical and applied interest. The solution to this problem is an effective application of the theory of viscoelasticity to real processes. Therefore, the methods and problems of pipeline vibrations attract much attention from researchers. This study is devoted to solving the above problems and therefore its subject is relevant. The paper considers the results of numerical simulation of the processes of vibration of a composite pipeline based on the theory of shells during the flow of a pulsating liquid through it. A mathematical model of vibration of a composite pipeline was developed. A computational algorithm was developed for solving problems of vibrations of composite pipelines conveying pulsating liquid.
Ketogenic vs plantogenic diets for health: a review article
Authors: Dos Santos Hildemar , Han Diane , Perez Mayabel , Johnson Summer , Shaheen Razaz 
Published: April 2022

PurposeTo gain a better and more comprehensive understanding, this study aims to investigate the literature to explore the two popular diets’ health benefits and concerns. Google Scholar and PubMed were used to search for available and relevant nutrition and health articles that pertain to the benefits and concerns of plantogenic and ketogenic diets. Search terms like low carbohydrate, diet, ketogenic, vegetarian and chronic diseases were used. Information was obtained from review articles and original research articles and checked for accuracy. Ketogenic diets have been used for a long time for convulsion in children and now reappeared for weight loss purposes.Design/methodology/approachKetogenic and plantogenic (plant-based) diets have been adopted today by many professionals and the public.FindingsKetogenic diets have been used for a long time for convulsion in children and now reappeared for weight loss purposes. Plantogenic diets also have been practiced for many years for religious, health and environmental reasons. Compared to plantogenic diets, ketogenic diets lack long-term evidence of its potential benefits and harm.Research limitations/implicationsMaybe Lacto-ovo vegetarian and pesco-vegetarian (eat fish but not meats) diets are OK. However, for strict plantogenic diets (total plantogenic/vegan diet), the risk of mineral or vitamin deficiency is present (Melinaet al., 2016). Of particular concern is dietary vitamin B12, which is obtained mostly from animal sources (Melinaet al., 2016). A long-term deficiency of vitamin B12 can lead to macrocytic anemia and cause neuro and psychological effects (Obeidet al., 2019). Also, omega-3 fatty acids may be deficient in such a diet and probably need to be supplemented on those who follow the total plantogenic diet (Melinaet al., 2016). Other deficiencies of concern would be zinc, iron, calcium, vitamin D and iodine (Melinaet al., 2016). Another disadvantage is that many junk foods could be easily classified within the plantogenic diet, such as sugar, cakes, French fries, white bread and rice, sugar-sweetened beverages and sweets in general. These items are related to higher weight gain and, consequently, to a higher incidence of diabetes and other chronic diseases (Schulzeet al., 2004; Maliket al., 2006; Funget al., 2009).Originality/valuePlantogenic diets were concluded to have sustainable health benefits for humans and the environment over ketogenic diets, which could be used but under professional follow-up only.

Authors: Kaur Itinpreet , Mishra Geeta , Farooqi Rahela 
Published: April 2022

PurposeAlthough existing literature abounds with actual diversity research, there is scant work on perceived diversity. This research aims to investigate the impact of employees' perception of workplace diversity on job satisfaction and turnover intentions. Further, the research analyses the gender-moderating effect between the hypothesized connection.Design/methodology/approachCurrent research work uses a structural equation modeling (SEM) approach to analyze the hypothesized connection with 222 full-time employees working in the Indian service sector.FindingsStudy results showed that employees' perception of workplace diversity has a significant negative impact on job satisfaction, while having a significant positive effect on employees' turnover intentions. Moreover, employees' perception of workplace diversity does not vary across gender.Originality/valueThough research work on perceived diversity is scant and growing at a slow pace, the current study adds to the diversity studies by assessing diversity through employees' perceptions instead of gleaning the actual diversity index.

Authors: Ando Yoriko , Ohshima Yuichiro , Yanagishita Takeshi , Watanabe Hitomi , Tamada Yasuhiko , Akiyama Masashi , Watanabe Daisuke 
Published: April 2022

AbstractHead and forehead hyperhidrosis (HFH) is a disease that causes a large amount of sweating from the head region, and it significantly reduces patients' quality of life. Only a few reports have shown the effectiveness of botulinum toxin type A (BTX‐A) local injection therapy (BTX‐A therapy) for HFH. To clarify the benefits of BTX‐A for HFH, BTX‐A therapy was performed in 15 patients, and its efficacy was evaluated. The amount of sweating was measured by the ventilation capsule method and Minor's iodine‐starch test. Evaluation was also performed using the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI). In most cases, a remarkable antiperspirant effect was observed from 2 weeks after the injection, and the effect lasted for approximately 30 weeks. HDSS and DLQI improved along with the decrease in sweating. Two patients (13.3%) complained of transient mild ptosis. There were no serious side‐effects. This study showed that BTX‐A therapy is a safe and effective treatment for HFH.
