An Educational Outreach Program: A Trauma System's 5-Year Experience
Authors: Archuleta Michael , McGraw Constance , D'Huyvetter Cecile , Mains Charles W.
Published: May 2022

BACKGROUND:

The American College of Surgeons Committee on Trauma requires Level I and II trauma centers to provide educational outreach to lower-level facilities. Although outreach is a required part of any trauma system, very little is published on the resources required for a successful program.

OBJECTIVE:

The purpose of this article is to provide a comprehensive roadmap of the required components to achieve a successful trauma outreach program.

METHODS:

This project describes the development and implementation of an educational outreach program from January 2016 to December 2020 that has grown from 27 facilities within one western state to 49 facilities across 14 different states. Program components measured include the number and attendance of trauma courses offered, including the Trauma Nursing Core Course (TNCC), Advanced Trauma Life Support (ATLS), Rural Trauma Team Development Course (RTTDC), the number of trauma meetings and webinars provided, total trauma center designation and reviews, total states reached, and total trauma center collaborations.

RESULTS:

From 2016 to 2020, the program more than doubled the number of TNCC and ATLS courses, maintained the number of RTTDC offered, and observed attendance rate increases of 33% and 11% for TNCC and ATLS courses, respectively. Outreach leadership attended 44 trauma meetings and educational webinars using virtual platform technology, nearly doubling the trauma center outreach with expansion across 14 states resulting in important changes in practice.

CONCLUSION:

With administrative support, effective leadership, and technology, outreach programs can serve as important resources for statewide trauma systems.

Authors: Odaman Al Işik , Demirağ Bengü , Erdem Melek , Genç Sinan , Karapinar Tuba H.
Published: May 2022

Objective:

Hepatic hemangiomas (HH) are the most common vascular tumors of the liver. It is important to distinguish hemangiomas from malignant liver tumors.

Materials and Methods:

The patients 0 to 1 years old, were diagnosed with HH and followed up in the oncology outpatient clinic between 2009 and 2020 were included in the study.

Results:

A total of 127 patients with the diagnosis of HH were included in the study. Of the patients, 99 (78%) had focal, 20 (15.7%) had multifocal, and 8 (6.3%) had diffuse HHs. Surgery was performed and the diagnosis was confirmed histopathologically in 6 patients (4.7%). During the follow-up, 16 (12.5%) patients received medical treatment. Thirteen (10.2%) were treated with propranolol, 2 (1.5%) with corticosteroids, and 1 (0.8%) with propranolol and corticosteroids. Complete response was obtained in 9 (9/16) patients and partial response was obtained in 6 (6/16) patients with medical treatment.

Conclusion:

Although HH is a benign tumor, it is important to make its differential diagnosis with malignant tumors of the liver. Over the years, the need for histopathologic examination for diagnosis has decreased. The success rate of propranolol is high, and the need for other treatment options with a high side-effect profile has decreased significantly since 2008.
Filtering Out the Facts: Recommendations to Optimize Performance of In-Line Filters for Parenteral Nutrition and Injectable Lipid Emulsion Infusions
Authors: Gill Marianne , Hirsch Adina , Wilson Nicole
Published: May 2022

The use of an in-line, 1.2-μm filter is recommended for the intravenous (IV) infusion of parenteral nutrition (PN), also known as 3-in-1, total nutrient admixture (TNA), or all-in-one, and injectable lipid emulsions (ILEs) infused alone through a separate IV line. While filtration of TNA was mandated in 1994 to improve patient safety, the recommendation for filtering lipid emulsions alone is relatively new and has not been adopted by all clinicians. In addition, literature references and postmarket surveillance data cite the occurrence of infusion pump occlusion alarms, which may be indicative of a clogged filter. The following review article provides an overview of filter recommendations for PN and ILE, describes the challenges of filtration with PN and ILE, and includes recommendations to minimize pump occlusion alarms that may occur from a clogged filter.

Authors: Wood Laura S. , Conway Dawn , Lapuente Maria , Salvador George , Fernandez Gomez Sheila , Carroll Bullock Andrea , Devgan Geeta , Burns Kathleen D.
Published: May 2022

Immune checkpoint inhibitors, such as programmed cell death ligand 1 inhibitors pembrolizumab, nivolumab, atezolizumab, and avelumab, are used to treat patients with advanced urothelial carcinoma (UC). Based on data from the phase 3 JAVELIN Bladder 100 trial, avelumab first-line (1L) maintenance is now considered the standard-of-care treatment for patients with locally advanced or metastatic UC who responded or experienced disease stabilization after 1L platinum-containing chemotherapy, and it is the only category 1 preferred checkpoint inhibitor maintenance option in the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology for patients with cisplatin-eligible and cisplatin-ineligible locally advanced or metastatic UC. This article reviews key considerations related to avelumab 1L maintenance therapy that infusion nurses should be familiar with, including dosing, administration, and immune-related adverse event recognition and management, to ensure safe and appropriate use of this important and impactful therapy.
Development of a Quality Assessment Tool for Outpatient Infusion Clinics: A Literature Review and Pilot Survey
Authors: Hu Elaine , Shams Maryam , Shirvani Daniel , Badii Maziar
Published: May 2022

This study aimed to develop a quality assessment tool for outpatient infusion clinics, as a lack of literature exists on the subject. The authors conducted a literature review targeting studies since 2016 to identify variables that affect patient satisfaction in outpatient infusion clinics. Due to the limited number of relevant studies found, the authors shadowed 2 infusion clinic nurses to capture additional determinants of outpatient infusion clinic quality. A total of 72 variables relevant to an outpatient infusion quality assessment tool were listed. From this list of variables, a pilot survey was conducted at an outpatient rheumatology infusion clinic to assess patient satisfaction with 16 variables of interest. The pilot survey (N = 43) revealed that patients were relatively dissatisfied with walking to clinics, lack of access to public transit, lack of parking and/or free parking, lack of privacy, and flexible scheduling and/or cancellation policies. These findings demonstrate how the assessment tool may highlight specific areas of concern at an infusion clinic to identify targets for future quality improvement initiatives. Therefore, the tool presented has the potential to improve the quality of care provided to patients attending infusion facilities.

Published: May 2022

OBJECTIVE

The objective of this multisite study was to explore the professional and personal experiences of US nurse managers (NMs) during the COVID-19 pandemic.

BACKGROUND

NMs are the most accessible and visible nurse leaders to the frontline staff during this pandemic.

METHODS

Thirty-nine NMs from 5 health systems across the US participated in focus groups in this qualitative study. Data were analyzed using a constant comparative method.

RESULTS

Three major themes were identified: challenges, feelings and emotions, and coping. Subthemes emerged within each major theme.

CONCLUSION

NMs across the country accepted considerable responsibility at great professional and personal consequence during the pandemic. NMs experienced challenges, ethical dilemmas, and expressed negative emotions. As the usual coping strategies failed, NMs reported that they are considering alternative career choices. This work provided evidence to help senior leaders strategize about mechanisms for reducing managerial dissonance during times of stress.

Published: May 2022

Nurse leaders need real-time, accurate data to design care delivery models and make decisions that reflect the patient populations they serve. To support nurse leader practice and optimize patient care, we developed a unit profile dashboard to describe the unique characteristics of patient populations cared for on each clinical unit at our hospital. In this article, we describe dashboard development, challenges, use cases, and plans for data analytics to further advance nursing practice.
Research on Relationship Between Dysphagia and Sudden Death After Medullary Infarction
Authors: Zou Xuan , Jing Xiyue , Xing Yonghong , Hong Yan , Zhao Wenjuan , Zhou Guanen
Published: May 2022

Background:

Medullary infarction (MI) often leads to severe dysphagia and sudden death. We investigated whether dysphagia was associated with sudden death.

Methods:

Patients with MI were divided into sudden death group and nonsudden death group. Dysphagia was evaluated in 2 ways: the water-swallowing test (WST) points and the degree of dysphagia. Random undersampling (RUS), random oversampling (ROS), and synthetic minority oversampling technique (SMOTE) techniques were used to process the original data and solve the imbalance problem between 2 classes. Univariate and multivariate logistic regressions were used to analyze the association between the independent variables (WST and degree of dysphagia) and the dependent variable (sudden death or not), while the National Institutes of Health Stroke Scale (NIHSS) score was used as a control.

Results:

Univariate logistic regression analysis showed that for all resampling methods, both the WST and NIHSS were risk factors for sudden death after MI. For multivariable logistic regression, the fitting effect of RUS logistic regression was satisfactory, which showed the same results. The results of the univariate logistic regression analysis of dysphagia degree showed that for all resampling methods, compared with no dysphagia, both mild to moderate dysphagia degree and severe dysphagia degree were risk factors for sudden death. For multivariable logistic regressions, the logistic regressions of the original data and the RUS resampling method were satisfactory which showed the same results.

Conclusions:

Dysphagia is closely related to sudden death after MI. The more severe the dysphagia, the higher is the incidence of sudden death.
HIV Incidence in Botswana Rural Communities With High Antiretroviral Treatment Coverage: Results From the Botswana Combination Prevention Project, 2013–2017

Published: May 2022

Background and Setting:

The Botswana Combination Prevention Project demonstrated a 30% reduction in community HIV incidence through expanded HIV testing, enhanced linkage to care, and universal antiretroviral treatment and exceeded the Joint United Nations Programme on HIV/AIDS 90–90–90 targets. We report rates and characteristics of incident HIV infections.

Methods:

The Botswana Combination Prevention Project was a community-randomized controlled trial conducted in 30 rural/periurban Botswana communities from 2013 to 2017. Home-based and mobile HIV-testing campaigns were conducted in 15 intervention communities, with 39% of participants testing at least twice. We assessed the HIV incidence rate [IR; number of new HIV infections per 100 person-years (py) at risk] among repeat testers and risk factors with a Cox proportional hazards regression model.

Results:

During 27,517 py, 195 (women: 79%) of 18,597 became HIV-infected (0.71/100 py). Women had a higher IR (1.01/100 py; 95% confidence interval: 0.99 to 1.02) than men (0.34/100 py; 95% confidence interval: 0.33 to 0.35). The highest IRs were among women aged 16–24 years (1.87/100 py) and men aged 25–34 years (0.56/100 py). The lowest IRs were among those aged 35–64 years (women: 0.41/100 py; men: 0.20/100 py). The hazard of incident infection was the highest among women aged 16–24 years (hazard ratio = 7.05). Sex and age were significantly associated with incidence (both P < 0.0001).

CONCLUSIONS:

Despite an overall reduction in HIV incidence and approaching the United Nations Programme on HIV/AIDS 95–95–95 targets, high HIV incidence was observed in adolescent girls and young women. These findings highlight the need for additional prevention services (pre-exposure prophylaxis and DREAMS) to achieve epidemic control in this subpopulation and increased efforts with men with undiagnosed HIV.
Noncanonical imprinting sustains embryonic development and restrains placental overgrowth

Published: May 2022

Genomic imprinting regulates parental origin-dependent monoallelic gene expression. It is mediated by either germline differential methylation of DNA (canonical imprinting) or oocyte-derived H3K27me3 (noncanonical imprinting) in mice. Depletion of Eed, an essential component of Polycomb repressive complex 2, results in genome-wide loss of H3K27me3 in oocytes, which causes loss of noncanonical imprinting (LOI) in embryos. Although Eed maternal KO (matKO) embryos show partial lethality after implantation, it is unknown whether LOI itself contributes to the developmental phenotypes of these embryos, which makes it unclear whether noncanonical imprinting is developmentally relevant. Here, by combinatorial matKO of Xist, a noncanonical imprinted gene whose LOI causes aberrant transient maternal X-chromosome inactivation (XCI) at preimplantation, we show that prevention of the transient maternal XCI greatly restores the development of Eed matKO embryos. Moreover, we found that the placentae of Eed matKO embryos are remarkably enlarged in a manner independent of Xist LOI. Heterozygous deletion screening of individual autosomal noncanonical imprinted genes suggests that LOI of the Sfmbt2 miRNA cluster chromosome 2 miRNA cluster (C2MC), solute carrier family 38 member 4 (Slc38a4), and Gm32885 contributes to the placental enlargement. Taken together, our study provides evidence that Xist imprinting sustains embryonic development and that autosomal noncanonical imprinting restrains placental overgrowth.

Authors: Seth Manisha , Sethi Deepa , Yadav Lalit Kumar , Malik Nishtha
Published: May 2022

Purpose

This study aims to analyze the impact of ethical leadership on organizational citizenship behavior and turnover intention of employees working in the financial sector, considering procedural justice as a mediator.

Design/methodology/approach

Data was collected from 306 employees working in the financial sector (banking, insurance and mutual fund) in India. The data was collected in two phases to avoid common method bias by using standardized close-ended questionnaires. Data for this study was assessed using Smart Partial Least Square (PLS) 3.

Findings

The results show that ethical leadership is significantly associated with procedural justice, organizational citizenship behavior and turnover intention. Further procedural justice acts as a mediator between ethical leadership and organizational citizenship behavior; also between ethical leadership and turnover intention.

Originality/value

The research contribute in understanding the role of procedural justice as a mediator between ethical leadership and organizational citizenship behavior and turnover intention for the employees working in the financial sector in India.
Bending of variable thickness rectangular thin plates resting on a double-parameter foundation: integral transform solution
Authors: Fu Guangming , Tuo Yuhang , Sun Baojiang , Shi Chen , Su Jian
Published: May 2022

Purpose

The purpose of this study is to propose a generalized integral transform technique (GITT) to investigate the bending behavior of rectangular thin plates with linearly varying thickness resting on a double-parameter foundation.

Design/methodology/approach

The bending of plates with linearly varying thickness resting on a double-parameter foundation is analyzed by using the GITT for six combinations of clamped, simply-supported and free boundary conditions under linearly varying loads. The governing equation of plate bending is integral transformed in the uniform-thickness direction, resulting in a linear system of ordinary differential equations in the varying thickness direction that is solved by a fourth-order finite difference method. Parametric studies are performed to investigate the effects of boundary conditions, foundation coefficients and geometric parameters of variable thickness plates on the bending behavior.

Findings

The proposed hybrid analytical-numerical solution is validated against a fourth-order finite difference solution of the original partial differential equation, as well as available results in the literature for some particular cases. The results show that the foundation coefficients and the aspect ratio b/a (width in the y direction to height of plate in the x direction) have significant effects on the deflection of rectangular plates.

Originality/value

The present GITT method can be applied for bending problems of rectangular thin plates with arbitrary thickness variation along one direction under different combinations of loading and boundary conditions.
Climate risk disclosure and climate risk management in UK asset managers
Authors: Greenwood Noelle , Warren Peter
Published: May 2022

Purpose

Framed within global policy debates over the need for private financial flows to align with the capital requirements of the Paris Agreement, this paper examines UK asset managers in their approaches to disclosing and managing climate risk. This paper identifies and evaluates climate risk management practices among this under-researched investor group in their capacity to address fundamental behavioural obstacles to low-carbon investment.

Design/methodology/approach

This paper takes an inductive approach to document analysis, applying content and thematic analysis to the annual disclosures of the 28 largest UK asset managers (by assets under management), including the investment management arms of insurance and pension companies.

Findings

The main takeaway from this research is that today’s climate risk management strategies hold potential to effectively address traditionally climate risk-averse investor behaviour and investment processes in the UK asset management context. However, this research finds that the use of environmental, social and governance (ESG) investment strategies to mitigate climate risks is a “grey area” in which climate risk management practices are undefined within broad sustainability and responsible investment agendas. In doing so, this paper invites further research into the extent to which climate risks are considered in ESG investment.

Originality/value

This paper contributes to research in sustainable finance and behavioural finance, by identifying the latest climate risk management techniques used among UK-headquartered asset managers and uniquely evaluating these in their capacity to address barriers to low-carbon investment arising from organisational behaviours and processes.
What's interesting in entrepreneurial education research? Identifying conversants sharing common interests in the field
Authors: Landström Hans , Gabrielsson Jonas , Politis Diamanto , Sørheim Roger
Published: May 2022

Purpose

In this study, the authors develop knowledge and insights on how the perception of interestingness influences the structure and focus of conversations in entrepreneurial education (EE) research. In particular, the authors elaborate on what is perceived as interesting among different subgroups of EE researchers, and not least, how EE researchers can identify and engage in scholarly conversation within the field.

Design/methodology/approach

The study is based on a unique database with web-based responses from 465 EE researchers from around the world. The authors conduct analyses of both open-ended and closed questions. The open-ended questions are analyzed by inductive categorization. The closed questions are subject to factor and cluster analyses.

Findings

The findings suggest that EE research is a topic-oriented field, characterized by a strong focus on novel and challenging research issues. In addition, the field is individualistic and fragmented, and the perception of interestingness differs between five subgroups of EE researchers, whose members have a somewhat different perception of interestingness. Accordingly, the authors also find different core conversations going on within the field. Obviously, these conversations tend to be triggered by the field's obsession with novelty and challenging research, but several conversations are related to practically relevant research, as well as methodological and theoretical discussions.

Originality/value

This is the first study to elaborate on the perception of interestingness among EE researchers and the conversations going on within the field. In the study the authors have explored the characteristics of EE research based on the perception of interestingness among the researchers within the field. In this respect, this study contributes insights on how current and aspiring EE researchers can find and build scholarly conversations embedded in passionate interest, while concurrently disseminating and accumulating knowledge on EE together with like-minded peers.
Impact of urban rehabilitation: evidence from subdivided units in Hong Kong
Authors: Liang Cong , Hui Eddie Chi Man , Yip Tsz Leung
Published: May 2022

Purpose

This paper aims to explore one question: to what extent does urban rehabilitation impact the housing search cost of the low-income tenants.

Design/methodology/approach

This paper adopts the fixed effects time-on-market (TOM) model and pricing model to study the research question.

Findings

Urban rehabilitation lifts the subdivided units (SDUs’) prices by around 7%. For the SDU located in old districts, urban rehabilitation gives rise to the rental price up by 11%–12%. The SDUs in the area without urban rehabilitation experience a short marketing period of 16%–17%. The SDU located in the old district that is without urban rehabilitation would have a short marketing time.

Originality/value

To the best of the authors’ knowledge, this is the pioneering research to investigate the relationship between rehabilitation and low-income rental housing from the improved search theory. The improved search theory posits that under the circumstance of urban rehabilitation, low-income tenants’ options are limited and the search behavior will be restricted in the affordable areas, and then TOM will be shortened. With the concentration of SDUs in Hong Kong, the test of the search theory is broken down into two hypotheses. (H1) Urban rehabilitation leads to low-income housing prices increase. (H2) Low-income housing located in areas without urban rehabilitation has a shorter TOM.
The impacts of industry environment on software insourcing, outsourcing, and buying
Authors: Liu Xiaowei , Qu Wen Guang , Pinsonneault Alain
Published: May 2022

Purpose

Nowadays, an increasing number of firms choose to develop proprietary software, instead of buying packaged software. What factors will affect different types of software investments? According to the environment-strategy alignment research, environment should be an influential factor. However, environment's role has received scarce attention in the literature. The authors' study addresses this research gap by investigating how industry environment affects different types of software investments. The study identifies three types of software investments (software insourcing, outsourcing, and buying) and examines how the characteristics of the industry environment (including industry munificence, dynamism, and concentration) influence each software investment.

Design/methodology/approach

The generalized least squares (GLS) model and the ordinary least squares with panel-corrected standard errors (OLS-PCSE) model are applied to test the hypotheses, based on industry-level panel data from the US Bureau of Economic Analysis (BEA).

Findings

The analysis shows that industry munificence, dynamism, and concentration have different impacts on software insourcing, outsourcing, and buying, respectively.

Originality/value

This study classifies software investment into three types – software insourcing, outsourcing, and buying and investigates how the industry environment affects them. The findings suggest that research should distinguish among software insourcing, outsourcing, and buying due to their different characteristics.
Non-empirical ISO 9241-210:2019-based usability evaluation using fuzzy inference analyser: a special issue on interactive social robots
Authors: Asemi Adeleh , Asemi Asefeh , Tahaei Hamid
Published: May 2022

Purpose

The objective of this research was to develop a new and highly accurate approach based on a fuzzy inference system (FIS) for the evaluation of usability based on ISO 9241-210:2019. In this study, a fully automated method of usability evaluation is used for interactive systems with a special look at interactive social robots.

Design/methodology/approach

Fuzzy logic uses as an intelligent computing technique to deal with uncertainty and incomplete data. Here this system is implemented using MATLAB fuzzy toolbox. This system attempted to quantify four criteria that correlate highly with ISO 9241-210:2019 criteria for the evaluation of interactive systems with maximum usability. Also, the system was evaluated with standard cases of computer interactive systems usability evaluation. The system did not need to train various data and to check the rules. Just small data were used to fine-tune the fuzzy sets. The results were compared against experimental usability evaluation with the statistical analysis.

Findings

It is found that there was a high strong linear relation between the FIS usability assessment and System Usability Scale (SUS) based usability assessment, and authors’ new method provides reliable results in the estimation of the usability.

Research limitations/implications

In human-robot systems, human performance plays an important role in the performance of social interactive systems. In the present study, the proposed system has considered all the necessary criteria for designing an interactive system with a high level of user because it is based on ISO 9241-210:2019.

Practical implications

For future research, the system could be expanded with the training of historical data and the production of rules through integrating FIS and neural networks.

Originality/value

This system considered all essential criteria for designing an interactive system with a high level of usability because it is based on ISO 9241-210:2019. For future research, the system could be expanded with the training of historical data and the production of rules through integrating FIS and neural networks.
Wholesaler echelon and Industry 4.0 in circular supply chains – a systematic review
Authors: Stocco Lucas Conde , Cezarino Luciana Oranges , Liboni Lara Bartocci , Venkatesh V.G.
Published: May 2022

Purpose

This paper aims to analyse systematically previous literature that sought to understand the formation of circular supply chains (CSCs) and propose a research agenda for implementing circular economy 4.0 in the wholesale industry.

Design/methodology/approach

The research is based on a systematic literature review.

Findings

There is a prevalence of research related to manufacturing and how industrial complexes can establish practices linked to the circular economy. The reviewed papers in this study can be classified into three perspectives: systemic analysis, institutional perspective and operational perspective. Considering these categories and the wholesaler perspective, there is a scope to explore Industry 4.0 technologies applications with wholesale distributors and their contributions to the reverse flow of waste along the CSC. In addition, it is interesting to examine the interpretation of wholesale distributors on circularity, and how these members can contribute to filling the information gaps between industries and retailers based on the concepts of circular economy and Industry 4.0, and how they can contribute to establishing public policies for proper waste recycling methods.

Originality/value

First, this research considers the wholesaler the exclusive supply chain member under the influence of Industry 4.0 and highlights its importance in firms' circular operations. Second, it provides an inclusive plan for the other stakeholders to interact with the wholesaler echelon to design and operate under 4.0 technologies to consolidate effective CSCs.
Quality assurance for technological institutes in Mexico: competition and inequity
Authors: Didou Aupetit Sylvie
Published: May 2022

Purpose

This study aims to analyze the external quality assurance (EQA) strategies of Technological Institutes (TIs) in Mexico, between 2010 and 2020. For this purpose, this study tracks sectoral reforms and institutional adaptation processes toward fulfilling accreditation indicators. This study considers accreditation as an emergent strategy for the governance and quality improvement of the subsystem, historically oriented towards contributing to social equity and national development projects. This study also examines the links between evaluation, quality assurance and the restructuring of public, technological higher education.

Design/methodology/approach

This study performs a state-of-the-art and exploratory study. This study explores the relationship between quality assurance, non-traditional institutions and regulation in Mexico. This study covers an issue that has been absent from research into the technological sector, particularly research into autonomy and leadership within its institutions. This study obtains qualitative information on those issues through interviews and two focus groups.

Findings

Mechanisms such as regulatory schemes for the internal reform of TIs and sub-systemic prominence within the overall educational system show limitations owing to the inadequacy of accreditation indicators in accounting for the conditions in which TIs operate. To address this shortcoming and to aid TIs in accreditation endeavors, this study analyzes some features of this adaptive process that enable successful (student profiles, competitive admission criteria, teacher recruitment).

Research limitations/implications

The main limitation is that this paper reviews a sole country and presents just one case study. Other research on other higher education sub-systems can complete the analysis. In sum, there has been a lack of analysis of accreditation topics in Mexico, in the nontraditional institutions.

Practical implications

This study provides a diagnosis of barriers to the participation of TIs in rankings and accreditation mechanisms, and their repercussions on management issues, governance patterns and reforms.

Social implications

This study outlined some internal obstacles linked with centralized model of conduction (data for monitoring, consensus on priorities, capabilities and financing) and external factors (shortages of assurance quality framing and institutional profiles, satisfaction with the process).

Originality/value

This study explores relationships between quality assurance, non-traditional institutions and regulation in Mexico, attending a lacking point in the research on the technological sector and autonomy/leadership of its institutions.
Quality assurance and new public management: transformations in organizational structures, functions and roles in Argentine universities
Authors: Marquina Monica , Gimenez Graciela , Rodríguez Wenceslao , Mazzeo Ignacio
Published: May 2022

Purpose

The purpose of this paper is to study how quality assurance (QA) has impacted Argentina’s higher education system, how QA tasks are reflected on the organizational structure of institutions, which kind of professional profiles the new QA staff assume and to what extent university life is reconfigured from these changes.

Design/methodology/approach

The authors draw on data from three work fields: collection and analysis of institutional data; survey applied to a stratified sample of staff who perform QA functions; and in-depth interviews with institutional QA professionals. Results show that universities have created specific areas and developed new functions and roles in QA.

Findings

The authors have observed a growing presence of dedicated personnel trained in developing these functions, positioned further down a path that had formerly distanced academics from administrative and institutional decision-makers. Unlike European universities, no evident tension was found between traditional sectors and the new professionals.

Research limitations/implications

The limited number of responses of the quantitative data collection technique (survey) only allowed for a general and descriptive analysis. This limitation is compensated with two other methodological processes (documental analysis and in-depth interviews), that allowed to incorporate “type of university” as a variable analyse the data obtained.

Practical implications

Results can be useful for public policy to move toward new forms of monitoring internal institutional QA systems.

Originality/value

The research that supports this article aims at constructing our own categories to understand the same object that has been studied in developed countries, but in the Argentine-specific context.
Scheme of long distance power supply for electrified railway traction network based on traction cable
Authors: Wang Hui , Li Qunzhan , Liu Wei , Wang Chuang , Liu Tongtong
Published: May 2022

Purpose

The traction cable is paralleled with the existing traction network of electrified railway through transverse connecting line to form the scheme of long distance power supply for the traction network. This paper aims to study the scheme composition and power supply distance (PSD) of the scheme.

Design/methodology/approach

Based on the structure of parallel traction network (referred to as “cable traction network (CTN)”), the power supply modes (PSMs) are divided into cable + direct PSM and cable + autotransformer (AT) PSM (including Japanese mode, French mode and new mode). Taking cable + Japanese AT PSM as an example, the scheme of long distance power supply for CTN under the PSMs of co-phase and out-of-phase power supply are designed. On the basis of establishing the equivalent circuit model and the chain circuit model of CTN, taking the train working voltage as the constraint condition, and based on the power flow calculation of multiple train loads, the calculation formula and process for determining the PSD of CTN are given. The impedance and PSD of CTN under the cable + AT PSM are simulated and analyzed, and a certain line is taken as an example to compare the scheme design.

Findings

Results show that the equivalent impedance of CTN under the cable + AT PSM is smaller, and the PSD is about 2.5 times of that under the AT PSM, which can effectively increase the PSD and the flexibility of external power supply location.

Originality/value

The research content can effectively improve the PSD of traction power supply system and has important reference value for the engineering application of the scheme.
Attitune music: the econometrics of jazz
Authors: Soon Jan-Jan
Published: May 2022

Theoretical basis

This study aims to use a variant from the family of discrete choice models, i.e. the logit model, to analyse the relationship between the Y dependent and X explanatory variables. This model addresses the linear probability model's main drawback by constraining the probabilities of the Y outcome between 0 and 1. The logit model also offers an extra advantage, in that it can provide odd ratio estimations.

Research methodology

This is a compact case written specifically to teach statistics, econometrics and research method. It has an accompanying data set for the case-users to do hands-on statistical analyses. The data set has been collected from a questionnaire survey from the students enrolled in Attitune, i.e. the music school that the case protagonist founded.

Case overview/synopsis

The case revolves around a relatively new music school, Attitune Music, established in July 2017 in the heart of the capital city of a northern state in Malaysia. Michael Lee Wei-Pin was the founder of Attitune Music Sdn. Bhd. He was also one of the four music instructors of Attitune Music. His speciality instruments were the guitar and the piano. The case opens with the case protagonist, Michael, pondering over Attitune’s performance in terms of its music students’ enrolment. Attitune faced a major challenge – its student enrolment had remained more or less constant since its establishment. Low and/or constant number of students could ultimately translate into stagnant or even worse, shrinking revenues for Attitune. To attract more students, Michael had been toying with the idea of injecting new elements into Attitune’s music lessons, something different from what other music schools were offering and that could be unique selling points for Attitune. With this in mind, Michael surveyed Attitune’s students to gather information that could help him gauge the potential and feasibility of his idea.

Complexity academic level

This case is well positioned to be perhaps the pioneer Malaysian teaching case to be written to teach courses in statistics, econometrics and research methods. The case can be easily adapted to teach at either the introductory or at an advanced level.

Purpose

The purpose of the study is to examine the effect of value co-destruction on customer citizenship and negative electronic word of mouth (e-WOM) behaviors. In addition, the study aims to determine the mediating role of tourist citizenship between value co-destruction and negative e-WOM behaviors.

Design/methodology/approach

By using a convenience sampling method, data were collected from 704 customers, who purchased their touristic products through co-creation. The exploratory and confirmatory factor analyses were applied to the data obtained to determine the factors that make up the dimensions in the research model. The partial least squares-structural equation modeling (PLS-SEM) was used to evaluate the relationship in the research model proposed in the study.

Findings

The results of the study indicated that value co-destruction had an effect on customer citizenship behavior and negative e-WOM. While the helping behavior of customer citizenship had an effect on negative e-WOM, the advocacy behavior of customer citizenship had no effect on negative e-WOM. However, this study found only an indirect mediation effect of helping behavior in the relationship between value co-destruction and negative e-WOM.

Research limitations/implications

The research examined the antecedent behaviors that cause value co-destruction and the effects of these behaviors on the outcomes of the holiday experience. This information then was combined in a model and evaluated in a holistic framework. Theoretically, the research helps us understand the impact of value co-destruction behavior on citizenship behavior and on tourists’ negative e-WOM tendency. The research examines value co-destruction behavior and its effect on holiday-experience outcomes simultaneously.

Practical implications

The research provides a framework that tourism enterprises can use to produce and offer value-attributing services for their customers and to manage dysfunctional and disruptive business processes and behaviors to reduce value co-destruction. The research also provides a new way for practitioners in the tourism sector to understand and generalize the behavioral changes of tourists caused by value co-destruction during and after their experience.

Originality/value

The paper contributes to an understanding of value co-destruction antecedents and outputs from the customer perspective. Further, the research provides information to tourism businesses to effectively and efficiently manage the value co-creation process and prevent value co-destruction. The findings of the study will provide useful suggestions that will contribute to researchers and sectoral representatives.

Some patients with coronavirus disease 2019 (COVID‐19) develop skin manifestations. There may be regional and racial differences in the frequency and type of COVID‐19‐associated skin manifestations. There are, however, few reports on skin manifestations in COVID‐19 patients in Asia, including Japan. We retrospectively investigated the frequency, type, and clinical course of skin manifestations in Japanese patients with COVID‐19. From 22 February 2020 to 16 August 2021, 738 Japanese patients (median age 59 years, 55% male) with laboratory‐confirmed COVID‐19 on polymerase chain reaction or antigen tests were admitted to our hospital. We mainly admitted patients with mild to moderate severity who had symptoms such as cough, fever, and oxygen demand but did not require mechanical ventilation. A total of 2.8% (21/738) of the COVID‐19 patients treated at our hospital were diagnosed with viral eruptions caused by COVID‐19. Of the 21 patients, 19 developed erythematous papules, and two developed urticaria. There were no cases of pernio‐like lesions, known as COVID toes. The median duration from the onset of other COVID‐19 symptoms to the development of skin manifestations was 9 days. This study revealed that approximately 2–3% of Japanese patients with COVID‐19 developed COVID‐19‐associated viral eruptions, most of which were erythematous papules.
Do State Bans of Most‐Favored‐Nation Contract Clauses Restrain Price Growth? Evidence From Hospital Prices

Policy Points

Looking for a way to curtail market power abuses in health care and rein in prices, 20 states have restricted most‐favored‐nation (MFN) clauses in some health care contracts.

Little is known as to whether restrictions on MFN clauses slow health care price growth.

Banning MFN clauses between insurers and hospitals in highly concentrated insurer markets seems to improve competition and lead to lower hospital prices.

Context

Most‐favored‐nation (MFN) contract clauses have recently garnered attention from both Congress and state legislatures looking for ways to curtail market power abuses in health care and rein in prices. In health care, a typical MFN contract clause is stipulated by the insurer and requires a health care provider to grant the insurer the lowest (i.e., the most‐favored) price among the insurers it contracts with. As of August 2020, 20 states restrict the use of MFN clauses in health care contracts (19 states ban their use in at least some health care contracts), with 8 states prohibiting their use between 2010 and 2016.

Methods

Using event study and difference‐in‐differences research designs, we compared prices for a standardized hospital admission in states that banned MFN clauses between 2010 and 2016 with standardized hospital admission prices in states without MFN bans.

Findings

Our results show that bans on MFN clauses reduced hospital price growth in metropolitan statistical areas (MSAs) with highly concentrated insurer markets. Specifically, we found that mean hospital prices in MSAs with highly concentrated insurer markets would have been $472 (2.8%) lower in 2016 had the MSAs been in states that banned MFN clauses in 2010. In 2016, the population in our sample that resided in MSAs with highly concentrated insurer markets was just under 75 million (23% of the US population). Hence, banning MFN clauses in all MSAs in our sample with highly concentrated insurer markets in 2010 would have generated savings on hospital expenditures in the range of $2.4 billion per year.

Conclusions

Our empirical findings suggest banning MFN clauses between insurers and providers in highly concentrated insurer markets would improve competition and lead to lower prices and expenditures.
Host–guest inclusion complexes of hydroxytyrosol with cyclodextrins: Development of a potential functional ingredient for food application

Hydroxytyrosol (HT), a potent phenolic phytochemical, exerts positive health effects due to its antioxidant properties. However, it is highly reactive to oxygen, light, and heat and presents high instability. Alpha‐ and beta‐cyclodextrin (α‐CD, β‐CD) have structures that allow them to encapsulate a variety of hydrophobic molecules. The aim of this study was to examine the outcomes of the inclusion of HT into α‐CD and β‐CD. Aqueous solutions of HT and either α‐CD or β‐CD were prepared and freeze‐drying was applied for the encapsulation, in 1:1 and 2:1 molar ratios. The produced solid complexes were studied and characterized using NMR spectroscopy, differential scanning calorimetry (DSC) and attenuated total reflection‐Fourier transform infrared spectroscopy (ATR‐FTIR). Encapsulation efficiency (EE%), stability, and in vitro release of the encapsulated complexes under simulated digestion conditions were also evaluated. In both DSC thermograms and FTIR spectra of the inclusion complexes, absence of the characteristic peaks of HT and shifts of the CDs peaks were observed, showing an interaction between the molecules. NMR suggested a stronger complex formed between β‐CD and HT. The EE% of β‐CD/HT (1:1 and 2:1) complexes and α‐CD/HT (1:1) complex was found to be higher (83%, 76%, 78%, respectively), compared to α‐CD/HT (2:1) (51%). Data obtained support the encapsulation of HT in both CDs, revealing a potential interaction between them and an improvement in HT's thermal stability. Regarding the in vitro release study, both CD complexes had similar behavior and a controlled release of HT in the intestinal site was observed.

Practical Application

The encapsulation of hydroxytyrosol in cyclodextrins resulted in white amorphous food‐grade powders with no aroma and taste. Incorporation of these powders in foods could lead to an increase in their antioxidant content and offer an additional nutritional value.
