What explains the technical efficiency of banks in Tunisia? Evidence from a two-stage data envelopment analysis
Authors: Jelassi Mohamed Mehdi , Delhoumi Ezzeddine
Published: August 2021

In this study we examine the potential determinants of technical efficiency for the Tunisian commercial banking sector over the period of 1995–2017. First, we estimate banking technical efficiency with a radial and non-radial bootstrap data envelopment analysis. For the radial technique, we use an input-oriented approach and for non-radial we use the Range Adjusted Measure (RAM). Second, we use a double bootstrapping regression technique to estimate the influence of a set of eventual determinants on technical efficiency. Finally, based on all possible regressions, we gauge the overall effect of each determinant. Our results reveal that the input-oriented and RAM approach gave somewhat similar results. We found that the return on equity, the expense to income ratio, the loan to deposit ratio, and the growth rate are insignificant to Tunisian banking technical efficiency. In particular, banking technical efficiency increases with capitalization and inflation, whereas, it decreases with size, number of bank branches, management to staff ratio, and loan to asset ratio. In addition, we identified evidence supporting the moderate success of the last decade of reforms and a noticeable one for the post-revolution reforms in helping improve banking technical efficiency. The post-revolution reforms, largely revolving around reinforcing the rules of good governance and banking supervision, coupled with the restructuring of public banks, were found to be insufficient to raise overall banking technical efficiency despite improvement in the technical efficiency of private banks.
Profiling the pausing behaviour of EFL learners in real-time computer-aided writing: a multi-method case study
Authors: Shen Cuiping , Chen Ningyang
Published: August 2021

Technologically enhanced means and devices in language education and research have enabled an in-depth exploration of the dynamics of writing. This study investigated the pausing behaviour of eight Chinese English as a Foreign Language (EFL) learners at the tertiary level in performing an online writing task. Quantitative and qualitative data were collected using a combination of methods and techniques, including keystroke logging, screen recording videos, think-aloud protocols, and stimulated recall interviews to establish a profile of each learner’s pausing behaviour. The learners’ pause profiles were extensively analyzed with a comparative focus on similarities and differences in EFL learners’ pausing behaviour across writing skill levels. Overall, the findings revealed a general tendency for the learners to pause most frequently at a low text unit level, i.e., the lexical level. More specifically, less-skilled writers tended to pause more frequently than more-skilled writers at lower-level text units, whilst more-skilled writers chose to make more strategic pauses to gain overall control of their writing. Furthermore, these findings help reveal the intricate self-monitoring patterns that undergird individual writer’s pausing behaviour and relate these patterns to self-monitoring awareness, writing knowledge and experience, and writing habit. This small-scale multi-method study offers a glimpse into how EFL learners at different skill levels would respond to a real-time online writing task by using resources at their disposal and under conscious monitoring. Methodologically, it adds empirical evidence to previous literature on researching the computer-aided writing process with computer-aided tools and considers productive complementation and triangulation across research approaches and paradigms.
Opioid-free general anaesthesia for transthoracic oesophagectomy: does it improve postoperative analgesia and other recovery criteria? A prospective randomised study
Authors: Abdelrahman Tamer Nabil , Algharabawy Wael Sayed
Published: August 2021

Background

Side effects related to intraoperative opioid administration are well known. Recently, it was found that opioids may inhibit cellular immunity through their effects on natural killer cell activity, stimulate angiogenesis and accentuate cancer cell growth. Hence, peri-operative use of opioids might affect long-term oncological outcomes in cancer surgical patients. Opioid-free anaesthesia (OFA) is a methodology that dodges narcotic use during anaesthesia by using blends of several drugs added to common anaesthetic agents.

The study aims to test the impact of OFA in transthoracic oesophagectomy in comparison with opioid-based anaesthesia technique (OBA) on postoperative analgesia and recovery criteria (hemodynamics, respiratory rate and haemoglobin oxygen saturation).

Results

The postoperative VAS was significantly lower in OFA group (A) than OBA group (B) in the measured time points (immediate postextubation, 30 min, 2 and 4 h postoperative) withPvalues 0.001, 0.001, 0.0012 and 0.0065 respectively. The time passed till first rescue analgesia requested was significantly longer in OFA group (A) than OBA group (B) and the total dose of rescue analgesia given to the patients were significantly higher in group B than group A. The recorded postoperative respiratory rate was significantly faster in OBA group (B) than OFA group (A), and the haemoglobin oxygen saturation (SPO2) showed statistically significant lower values in the OBA group (B) than the OFA group (A).

Conclusions

We emphasise the perioperative safety and efficacy of the opioid-free anaesthesia techniques provided for transthoracic oesophagectomy with better postoperative analgesia and other post recovery criteria.

Trial registration

Interests and concerns regarding medical marijuana among chronic pain patients in Ohio: an online survey
Authors: Adams Daniel , Ofei-Tenkorang Nana Ama , Connell Patrick , Owens Alexa , Gothard Aaron , Souza Dmitri , Narouze Samer
Published: August 2021

Background

Since the legalization of medical marijuana (MMJ) in Ohio in 2018, many chronic pain (CP) patients have become interested in it as an alternative or adjunct to prescription opioids. This has not only created a need for pain management specialists to learn about this potential indication for MMJ but also for them to have more detailed knowledge of patient attitudes and willingness to comply with providers’ recommendations regarding its safe use with other pain medications. For this purpose, we surveyed CP patients in a region severely affected by the opioid crisis in order to provide better education, formulate treatment plans, and develop clinical policies.

Methods

We designed and administered the Medical Marijuana Interest Questionnaire (MMIQ) online to patients of the Western Reserve Hospital Center for Pain Medicine (CPM) with a diagnosis of CP who were not yet using MMJ. Questions addressed demographic and clinical characteristics, willingness to consider MMJ, and compliance with treatment plans and concerns. We then carried out a statistical analysis including Pearson chi-square, Spearman’s rho and Kendall’s tau tests to measure associations between variables to identify factors that may influence willingness to use MMJ.

Results

After sending 1047 email invitations to complete the MMIQ, 242 (23.1%) completed questionnaires were returned. The average age range of all respondents was 51-60 years, 171 (70.7%) were female and 147 (60.7%) were current opioid users. The 204 (84.3%) respondents who were willing to consider using MMJ were given access to the entire questionnaire. Of these, 138 (67.6%) reported wanting to use less opioids after starting MMJ and 191 (93.6%) were amenable to following their pain specialists’ recommendations about using MMJ concurrently with opioids. Their greatest concern on a 0-5 scale was affordability (2.98) and there was a statistically significant negative correlation between older age and preference for inhaled forms (p = 0.023).

Conclusion

The MMIQ was successful in eliciting important data regarding patients’ attitudes about MMJ for opioid titration and potential compliance. Our study was limited by being administered online rather than in-person, which skewed the demographic makeup of the sample. The MMIQ can be used to study similar populations or adapted to patients already using MMJ. Similar surveys of MMJ-experienced patients could be combined with chart reviews to study the success of these products for pain control and opioid substitution.
Cannabis for pain: a cross-sectional survey of the patient information quality on the Internet
Authors: Ng Jeremy Y. , Dzisiak Darragh A. , Saini Jessica B.
Published: August 2021

Background

Cannabis has increasingly become an alternative treatment for chronic pain, however, there is evidence of concomitant negative health effects with its long-term usage. Patients contemplating cannabis use for pain relief commonly see information online but may not be able to identify trustworthy and accurate sources, therefore, it is imperative that healthcare practitioners play a role in assisting them in discerning the quality of information. The present study assesses the quality of web-based consumer health information available at the intersection of cannabis and pain.

Methods

A cross-sectional quality assessment of website information was conducted. Three countries were searched on Google: Canada, the Netherlands, and the USA. The first 3 pages of generated websites were used in each of the 9 searches. Eligible websites contained cannabis consumer health information for pain treatment. Only English-language websites were included. Encyclopedias (i.e. Wikipedia), forums, academic journals, general news websites, major e-commerce websites, websites not publicly available, books, and video platforms were excluded. Information presented on eligible websites were assessed using the DISCERN instrument. The DISCERN instrument consists of three sections, the first focusing on the reliability of the publication, the second investigating individual aspects of the publication, and the third providing an overall averaged score.

Results

Of 270 websites identified across searches, 216 were duplicates, and 18 were excluded based on eligibility criteria, resulting in 36 eligible websites. The average summed DISCERN score was 48.85 out of 75.00 (SD = 8.13), and the average overall score (question 16) was 3.10 out of 5.00 (SD = 0.62). These overall scores were calculated from combining the scores for questions 1 through 15 in the DISCERN instrument for each website. Websites selling cannabis products/services scored the lowest, while health portals scored the highest.

Conclusion

These findings indicate that online cannabis consumer health information for the treatment/management of pain presents biases to readers. These biases included websites: (1) selectively citing studies that supported the benefits associated with cannabis use, while neglecting to mention those discussing its risks, and (2) promoting cannabis as “natural” with the implication that this equated to “safe”. Healthcare providers should be involved in the guidance of patients’ seeking and use of online information on this topic.
A review on nutritional composition, health benefits, and technological interventions for improving consumer acceptability of camel meat: an ethnic food of Middle East
Authors: Baba Waqas N. , Rasool Nuzhat , Selvamuthukumara M. , Maqsood Sajid
Published: August 2021

Camel meat is an ethnic food consumed across the arid regions of Middle East and North-East Africa. It can be a potential alternative red meat for human consumption worldwide. Camel meat is nutritionally as good as any conventional meat source, in fact has an edge over beef or lamb due to its low intramuscular fat, low cholesterol content, and high iron content. Camel meat quality is a function of age, breed, and type of muscle consumed. Various techniques such as aging, low-temperature storage, and pre-treatment with antioxidants improve the quality and shelf life of camel meat. Active packaging and fermentation are promising techniques to improve consumer acceptance and shelf-life of camel meat. Very limited research is available about the use of novel pre-treatments, packaging, and processing techniques that can improve the consumer acceptability of camel meat. Due to restricted use of camel meat and its products to ethnic regions, a review highlighting the nutritional potential and strategies to improve the quality of camel meat and its products may enhance its global acceptance as an alternative source of red meat.
Role of vitamin D, serum zinc, and serum iron deficiency in community-acquired pneumonia in children
Authors: Alsharkawy Asmaa Alhusseiny Ahmed , Rezk Ahmed R.
Published: August 2021

Background

Community-acquired pneumonia is a major cause of death among children. Inadequate nutrition disrupts the immune system and increases the susceptibility to infections. We aimed to evaluate the association between vitamin D, serum zinc, and iron, and pneumonia. A case-control study was conducted at the outpatient clinic and emergency room of Children’s Hospital. Thirty-one patients with community-acquired pneumonia and 36 healthy children (control group) underwent serum sampling for vitamin D, zinc, and iron.

Results

Most patients had mild form (n= 17, 54.8%). All patients survived and were discharged. The serum iron level showed a non-significant difference between pneumonia and control groups (p˃ 0.05). TIBC, vitamin D, and serum zinc were significantly lower in the patient group than the control group (Pvalue = 0.04, < 0.001, and 0.03, respectively). Vitamin D deficiency was highly associated with the severity of pneumonia (Pvalue = 0.008).

Conclusion

Adequate serum zinc and vitamin D levels may be protective against infection with community-acquired pneumonia in children aged from 2 months to 5 years old, but not iron.
Impact of corporate social responsibility on organization’s financial performance: evidence from Maldives public limited companies
Authors: Sameer Ibrahim
Published: August 2021

The main objective of this study is to determine the CSR disclosure and to find out the association between CSR and FP by the public companies of Maldives. This study used a mixed-method research choice and is longitudinal research. The study period was from 2014 to 2018. Data were collected from annual reports of the listed companies in MSE. The sampling technique used was judgmental sampling, and the data were analyzed from STATA 15 software by using panel data regression. The finding reveals that diversity and ROA, environment and ROE, diversity, and EPS, and when the size of the firm controlled, there exhibit significant negative relation between CSR and ROA; hence, it can conclude that there exists a significant negative relationship between CSR and FP. This study has implications for the academician and corporate world in understanding CSR and FP in developing countries like the Maldives. One of the main consequences of this study is the CSR framework adopted in this study which is not a custom-tailored instrument specific to the Maldives instead chose from another research paper. Further, the sample size was also very limited due to that generalization may not be possible in a large population. This paper spreads the understanding of the relationship between CSR and FP.
Gene expression profiling of epidermal cell types in C. elegans using Targeted DamID
Authors: Katsanos Dimitris , Ferrando-Marco Mar , Razzaq Iqrah , Aughey Gabriel , Southall Tony D. , Barkoulas Michalis
Published: August 2021

The epidermis of Caenorhabditis elegans is an essential tissue for survival because it contributes to the formation of the cuticle barrier as well as facilitating developmental progression and animal growth. Most of the epidermis consists of the hyp7 hypodermal syncytium, the nuclei of which are largely generated by the seam cells, which exhibit stem cell-like behaviour during development. How seam cell progenitors differ transcriptionally from the differentiated hypodermis is poorly understood. Here, we introduce Targeted DamID (TaDa) in C. elegans as a method for identifying genes expressed within a tissue of interest without cell isolation. We show that TaDa signal enrichment profiles can be used to identify genes transcribed in the epidermis and use this method to resolve differences in gene expression between the seam cells and the hypodermis. Finally, we predict and functionally validate new transcription and chromatin factors acting in seam cell development. These findings provide insights into cell type-specific gene expression profiles likely associated with epidermal cell fate patterning.
Accelerating deformation seismicity patterns before the March 3, 2021 Thessaly strong earthquake. First results
Authors: Chatzopoulos Georgios
Published: August 2021

A widely felt strong shallow earthquake with Mw 6.3 magnitude occurred in Thessaly (Central Greece) on March 3, 2021. This recent strong event attracted our interest to apply and evaluate the capabilities of the Accelerating Deformation method. Based on the recently proposed generalized Benioff strain idea which could be justified by the terms of Non-Extensive Statistical Physics (NESP), the common critical exponent was calculated in order to define the critical stage before a strong event. The present analysis comprised a complex spatiotemporal iterative procedure to examine the possible seismicity patterns at a broad region and identify the best one associated with the preparation process before the strong event. The starting time of the accelerating period, the size and location of the critical area are unknown parameters to be determined. Furthermore, although, the time of failure is already known, in the present research it was not set as a fixed value in the algorithm to define the other unknown parameters but instead different catalogue ending dates have been tried out to be with an objective way. The broad region to be investigated was divided with a square mesh and the search of events around a point has been carried on with different size circular and elliptical shapes. Among the obtained results, the solution which exhibits the most dominant scaling law behavior as well as the one which exhibits the smallest spatial area and yet the more dominant scaling law behavior are presented.

Evidence for adverse effects of cannabidiol (CBD) products and their non-conformity on the European food market – response to the European Industrial Hemp Association
Authors: Lachenmeier Dirk W. , Walch Stephan G.
Published: August 2021

An interesting and valuable discussion has arisen from our recent article (Lachenmeier et al., 2020) and we are pleased to have the opportunity to expand on the various points we made. Equally important, we wish to correct several important misunderstandings that were made by Kruse and Beitzke (2020) on behalf of the European Industrial Hemp Association (EIHA) that possibly contributed to their concerns about the validity of our data, toxicological assessment and conclusions regarding regulatory status of cannabidiol (CBD) products. First and foremost, our study did only assess the risk of psychotropic Δ9-tetrahydrocannabinol (THC) without inclusion of non-psychotropic Δ9-tetrahydrocannabinolic acid (THCA). Secondly, as this article will discuss in more detail, there is ample evidence for adverse effects of CBD products, not only in paediatric patients, but also in adult users of over-the-counter CBD products (including inadvertent “high” effects). Thirdly, the exposure and risk assessment was conducted using up-to-date guidelines according to the European Food Safety Authority (EFSA) and the German Federal Institute for Risk Assessment (BfR). And finally, the current legal situation in the European Union, without approval of any hemp extract-containing product according to the Novel Food regulation, actually allows blanket statements that all such products are illegal on the market, and this indeed would imply a general ban on the use and marketing of such products as food or food ingredients until such an approval has been granted. We hope that this reassures the F1000Research readership regarding the validity of our results and conclusions. We are pleased, though, that the EIHA has acknowledged the fact that there are non-compliant CBD products available, but according to our data these are a substantial fraction of the market.
Regional disparities in postnatal care among mothers aged 15-49 years old: An analysis of the Indonesian Demographic and Health Survey 2017
Authors: Cahyono Mochammad Nur , Efendi Ferry , Harmayetty Harmayetty , Adnani Qorinah Estiningtyas Sakilah , Hung Hsiao Ying
Published: August 2021

Background: In Indonesia, maternal mortality remains high, significantly 61.59% occur in the postnatal period. Postnatal care (PNC) provision is a critical intervention between six hours and 42 days after childbirth and is the primary strategy to reduce maternal mortality rates. However, underutilisation of PNC in Indonesia still remains high, and limited studies have shown the regional disparities of PNC in Indonesia.

Methods: This study aims to explore the gaps between regions in PNC service for mothers who have had live births during the last five years in Indonesia. This study was a secondary data analysis study using the Indonesian Demographic and Health Survey (IDHS) in 2017. A total of 13,901 mothers aged 15-49 years having had live births within five years were included. Chi-squared test and binary logistic regression were performed to determine regional disparities in PNC.

Results: Results indicated that the prevalence of PNC service utilisation among mothers aged 15-49 years was 70.94%. However, regional gaps in the utilisation of PNC service were indicated. Mothers in the Central of Indonesia have used PNC services 2.54 times compared to mothers in the Eastern of Indonesia (OR = 2.54; 95% CI = 1.77-3.65, p<0.001). Apart from the region, other variables have a positive relationship with PNC service, including wealth quintile, accessibility health facilities, age of children, childbirth order, mother's education, maternal occupation, spouse's age, and spouse's education.

Conclusion: The results suggest the need for national policy focuses on service equality, accessible, and reliable implementation to improve postnatal care utilisation among mothers to achieve the maximum results for the Indonesian Universal Health Coverage plan.
Comparison of cell size, chlorophyll fluorescence and cadmium (Cd2+) bioaccumulation between wild-type and mutant strains of Chlamydomonas reinhardtii upon exposure to Cd2
Authors: Ynalvez Ruby , Gonzalez-Cantu Hector , Vazquez-Cano Erick
Published: August 2021

Background: Heavy metal contamination presents a constant threat to biological systems. Simultaneously, heavy metals have become one of the major contaminants in the aquatic ecosystems. In this regard, the investigation of heavy metal-tolerance genes in algae is relevant. Chlamydomonas reinhardtii is a unicellular green alga, and an excellent model organism used in heavy metal studies. In C. reinhardtii, a novel gene designated as Cia7, was hypothesized to play a role in heavy metal homeostasis due to CIA7’s conserved cysteine-residue motif. This study compared two strains of C. reinhardtii, cc4425, the wild-type with the functional CIA7 protein and cc5013, the mutant strain with the disrupted cia7- gene. The hypothesis was that the expression of Cia7 contributes to an increased cadmium (Cd)-tolerance in C. reinhardtii. The Cd-tolerance would be described by physiological markers of microalgae health, and by intracellular accumulation of the metal.

Methods: The objectives of this study were (1) to compare chlorophyll fluorescence and cell size in cc4425 and cc5013 exposed to Cd2+, and (2) to compare Cd2+ bioaccumulation in cc4425 and cc5013 strains in different growth media. Flow cytometry, and inductively coupled plasma optical emission spectrometry (ICP-OES) analysis were performed.

Results: There was no significant statistical difference in Cd2+ bioaccumulation between the two strains, cc4425 and cc5013, regardless of growth media. However, a statistically significant difference in Cd2+ bioaccumulation (p<0.0001) was determined between the media (with acetate and without acetate).  The cia7- mutant, cc5013 was found to be more susceptible to a Cd2+-induced decrease in chlorophyll fluorescence and had a reduced cell size compared to cc4425, the wild-type strain.

Conclusions: These observed differences between the strains suggest that CIA7’s biological activity could play a direct or indirect role in increasing Cd tolerance in C. reinhardtii.
Conceptual design of smart multi-farm produce dehydrator using a low-cost programmable logic controller and raspberry pi
Authors: Oluwaleye Sunkanmi , Oguntosin Victoria , Idachaba Francis
Published: August 2021

Background: Acceptable food processing techniques require the removal of water contents from the crop or food sample without destroying the nutritional qualities of the food sample. This poses a strict requirement on the dehydrator or oven that will be used in the dehydrating techniques to have the ability to control both temperature and humidity of its drying chamber.

Methods: This work centres on how an autonomous multi-farm produce dehydrator that can also serve as an oven can be designed with a raspberry pi and a low-cost programmable logic controller (PLC). The dehydrator gives the users the flexibility to control both the drying chamber’s temperature and humidity from its web interface via a mobile device or the dehydrator’s HMI. Heat energy from the Liquid Petroleum Gas (LPG) is used so that the dehydrator can be readily available for commercial or industrial use.  The small electricity required to power the electronics devices is obtained from the hybrid power solution with an electric energy source from either the mains electricity supply or solar..

The design was tested by creating an operation profile from the proposed web application for the dehydrator. The operation trend was analysed from the web application’s Trendlines page.

Results: The report showed that both the temperature and humidity of the dehydrator could be controlled, and access to historical operation data will give insight to the user on how to create a better operation profile.

Conclusion: The setup described in this work, when implemented was able to produce a dehydrator/oven whose temperature and humidity can be perfectly controlled and its generated heat is evenly distributed in its drying chamber to ensure efficient and effective drying techniques use in crop preservation and food processing.
Early Marriage among young girls in Eastern Ethiopia: trend during 2008-2018
Authors: Abdurahman Dureti , Assefa Nega , Berhane Yemane
Published: August 2021

Early marriage practices undermine girls’ autonomy and seriously affect their physical and mental wellbeing. Monitoring the trends and understanding the drivers is essential in intervening against early marriage. However, many studies on early marriage in Ethiopia are cross-sectional, focusing only on the magnitude at a single point in time. Hence, we extracted data of girls of 10-17 years from Kersa Health and Demographic Surveillance System (Kersa HDSS) database for the period of 2008–2018 in order to examine the trends of early marriage. In this data note we provide the details of a research database of 24,452 girls in the age group of 10-17 years. The extracted data include date of marriage and the girls’ socio-demographic variables. Other variables considered to be potentially associated with timing of marriage were also extracted. The purpose of this publication is to describe the dataset for external researchers who may be interested in making use of it as a secondary use of their routinely collected data. This dataset is available at   https://doi.org/10.6084/m9.figshare.15034812.

Published: August 2021

Durante décadas, milhares de pessoas emigraram do Semiárido Nordestino para outras partes do Brasil, pela condição climática, que impõe limitações aos modelos de desenvolvimento historicamente propostos para a região. Argumentamos que políticas públicas de convivência com o Semiárido possibilitaram a permanência e mesmo o retorno populacional. Visamos compreender como políticas públicas de convivência com o Semiárido interferem na migração. A convivência com o Semiárido e o combate à seca são interpretadas por teorias relacionadas ao desenvolvimento. Metodologicamente, é uma pesquisa documental realizada com publicações de natureza diversa. Ao analisá-las, concluímos que as políticas públicas de convivência procuram garantir à população segurança hídrica, alimentar e estímulos à geração de renda, mudando seu padrão migratório.

Published: August 2021

Este artigo investigou a influência exercida pelo contexto de origem nas trajetórias de carreira de prestadoras de serviço de limpeza. Adotou-se, enquanto quadro teórico, a abordagem disposicional neobourdieusiana proposta por Jessé Souza. A abordagem metodológica privilegiou o uso de histórias de vida para analisar as trajetórias profissionais estudadas. Os resultados obtidos ilustram que os contextos de origem das entrevistadas, caracterizados por reduzidos volumes de capital e acentuada desorganização social, condicionaram suas trajetórias profissionais, marcadas por inserções pouco qualificadas em um mercado de trabalho competitivo. Tais resultados contribuem para colocar em xeque abordagens voluntaristas de carreiras que enfatizam a agência individual.

Corporate social responsibility as a determinant of tax aggressivity
Authors: Tardin Neyla , Rizzi Sevirino Lohami
Published: August 2021

This research verified whether the practices of corporate social responsibility (CSR) and tax aggressiveness are complementary, substitute or unrelated. A total of 1,081 observations from Brazilian companies listed on B3 were analyzed between 2010 and 2017. The survey used the guidelines of the Global Reporting Initiative (GRI) to measure the degree of CSR. The results show a substitution relationship between companies with a high GRI degree and tax aggressiveness when measured by the differences between accounting profit and taxable profit (BTD), however, this relationship becomes complementary if measured by the total taxes on the amount added (TTVA).
Scientific and Methodological Approaches to Creating a System of Pedagogical Diagnostics of the Level of Training and Development of Primary School Graduates
Authors: Kuznetsova M. , Vinogradova Natalya
Published: August 2021

The article discusses the problem of obtaining reliable information about the level of educational achievements of junior schoolchildren during

their transition to the next stage of school education. The implementation of the development goals of students at the initial stage of schooling, set by the Federal State Educational Standard of Primary General Education, requires pedagogical diagnostics, which makes it possible to establish the cause of the difficulties that children have in the course of studying various subjects. This ensures the timely intervention of the teacher in the learning process to provide each younger student with pedagogical assistance and support, which makes it possible to eliminate the individual difficulties that arise in him.

Personalized Priority Policies in Call Centers Using Past Customer Interaction Information
Authors: Hathaway Brett Alan , Emadi Seyed Morteza , Deshpande Vinayak
Published: August 2021

To increase revenue or improve customer service, companies are increasingly personalizing their product or service offerings based on their customers' history of interactions. In this paper, we show how call centers can improve customer service by implementing personalized priority policies. Under personalized priority policies, managers use customer contact history to predict individual-level caller abandonment and redialing behavior and prioritize them based on these predictions to improve operational performance. We provide a framework for how companies can use individual-level customer history data to capture the idiosyncratic preferences and beliefs that impact caller abandonment and redialing behavior and quantify the improvements to operational performance of these policies by applying our framework using caller history data from a real-world call center. We achieve this by formulating a structural model that uses a Bayesian learning framework to capture how callers’ past waiting times and abandonment/redialing decisions affect their current abandonment and redialing behavior and use our data to impute the callers’ underlying primitives such as their rewards for service, waiting costs, and redialing costs. These primitives allow us to simulate caller behavior under a variety of personalized priority policies and hence, collect relevant operational performance measures. We find that, relative to the first-come, first-served policy, our proposed personalized priority policies have the potential to decrease average waiting times by up to 29% or increase system throughput by reducing the percentage of service requests lost to abandonment by up to 6.3%.

Implementing Environmental and Social Responsibility Programs in Supply Networks Through Multiunit Bilateral Negotiation
Authors: Feng Qi , Li Chengzhang , Lu Mengshi , Shanthikumar J. George
Published: August 2021

Involving suppliers deep in the supply chain is critical for the success of environmental and social responsibility (ESR) initiatives. Administering ESR programs throughout a complex supply network, however, is challenging. In this paper, we apply a multiunit bilateral bargaining framework to coordinate ESR investments in a general supply network and analyze to what extent an ESR initiator should directly engage the higher-tier suppliers as opposed to delegating that responsibility to the first-tier suppliers. Our bargaining framework not only generalizes the conventional Shapley value approach by allowing the flexibility of modeling imbalanced power distribution among the firms but also provides an explicit way of implementing the resulting gain sharing among the firms through negotiated contract terms. We show that the eventual structure of ESR negotiation relationships can be derived by finding a shortest path tree in the supply network with the arc cost defined as the logarithm of the negotiating parties’ relative bargaining power. These developments allow us to analyze ESR implementation in generally extended supply networks. We find that the ESR initiator tends to delegate ESR negotiations to a supplier that is strong in negotiations with higher-tier suppliers. When the supply network is complex (i.e., wide and deep), directly engaging all suppliers can lead to a larger gain by the initiator than fully delegating the negotiations with higher-tier suppliers to the first-tier ones. However, as the network gets increasingly complex, the ESR initiator tends to directly engage a reduced percentage of higher-tier suppliers. We further extend our analysis to situations where the ESR relationships are sequentially formed in a decentralized manner, where the benefit of ESR depends on the collective choice of the firms’ investment levels, where multiple ESR programs are implemented in the network, and where ESR investments depend on the negotiation relationships.
