Improved particle filter-based estimation of a quadrotor subjected to uncertainties
Authors: Kaba Aziz , Ermeydan Ahmet 
Published: March 2022

PurposeThe purpose of this paper is to present an improved particle filter-based attitude estimator for a quadrotor unmanned aerial vehicle (UAV) that addresses the degeneracy issues.Design/methodology/approachControl of a quadrotor is not sufficient enough without an estimator to eliminate the noise from low-cost sensors. In this work, particle filter-based attitude estimator is proposed and used for nonlinear quadrotor dynamics. But, since recursive Bayesian estimation steps may rise degeneracy issues, the proposed scheme is improved with four different and widely used resampling algorithms.FindingsRobustness of the proposed schemes is tested under various scenarios that include different levels of uncertainty and different particle sizes. Statistical analyses are conducted to assess the error performance of the schemes. According to the statistical analysis, the proposed estimators are capable of reducing sensor noise up to 5x, increasing signal to noise ratio up to 2.5x and reducing the uncertainty bounds up to 36x with root mean square value of as low as 0.0024, mean absolute error value of 0.036, respectively.Originality/valueTo the best of the authors’ knowledge, the originality of this paper is to propose a robust particle filter-based attitude estimator to eliminate the low-cost sensor errors of quadrotor UAVs.

Authors: Corradini Flavio , Polini Andrea , Re Barbara , Rossi Lorenzo , Tiezzi Francesco 
Published: March 2022

PurposeThis paper aims at supporting business process designers in modelling collaborative scenarios in terms of hierarchical BPMN collaboration diagrams, to enforce consistency among different hierarchical levels.Design/methodology/approachThe proposed approach is based on a set of guidelines to apply during the modelling of hierarchical diagrams. These guidelines address consistency issues related to the hiding capability provided by sub-process and call activity elements, which may obscure behaviours at inner levels, especially exchange of messages, that are inconsistent with those in other hierarchical levels. A laboratory experience validates the guidelines' effectiveness.FindingsThe paper points out the issues of hierarchical diagrams, and the lack of support in this context from the existing BPMN modelling tools. Moreover, through a laboratory experience, the paper shows the benefits carried by the proposed guidelines concerning the quality of the modelled diagrams.Practical implicationsThe proposed guidelines have been implemented in a consistency checking tool that avoids consistency errors during the modelling activity. To foster its usage, the tool has been integrated into the Eclipse BPMN modelling environment.Originality/valueThe paper, employing consistency guidelines, provides a novel solution to the weaknesses of hierarchical modelling.
An online marketplace for archival services
Authors: Niu Jinfang 
Published: March 2022

Purpose
Online marketplaces, which provide on-demand goods or services through matching providers and consumers, have emerged in many sectors of the society. This paper aims to assess the need and speculate the design features of a specialized, online marketplace for archival services.

Design/methodology/approach
Interview data collected for a previous project were reanalyzed, and the websites of some online marketplaces were explored.

Findings
Existing general-purpose online marketplaces are useful but limited. Archivists and closely related professionals, including conservators, genealogists and public historians, need a specialized online marketplace to connect with their clients. This specialized online marketplace for archival services could adopt some useful features of existing online marketplaces.

Originality/value
To the best of the author’s knowledge, this is the first attempt to assess the need for an online marketplace for archival services.
Explanation and classification of technological entrepreneurship financing policies: lessons from Iran
Authors: Motiei Mohsen 
Published: March 2022

Purpose
As technological entrepreneurship has distinctive characteristics and needs particular conceptualizations, it is also important to have specific theoretical developments about its technological entrepreneurship. Studying the related domains like entrepreneurship and technology can be helpful in this path; however, their differences should be considered as well. The purpose of this study is to design a model in support of technological entrepreneurship. Since financing is considered as the main restriction on creating and developing technological entrepreneurship, the focus of this study is the research of financial policies of technological entrepreneurship..

Design/methodology/approach
This research is from the qualitative point of view and in terms of the purpose of application-development that has been done in the second part. At the first step, Iran’s (IRI) national comprehensive policies have been studied from 1993 to 2020; out of 52 documents, 7 were relevant, of which 38 policies were eventually selected. Then, policy statements were explored, and open coding and categorization has been done through theme analysis approach to attain fundamental themes and organizational themes. In the second step, the themes were extracted in the form of soft research method with the approach of interpretive structural modeling to level the financing policies of technological entrepreneurship in Iran.

Findings
The results show that the most important factors influencing financing and entrepreneurship in Iran are increasing the productivity of goods and services, supporting entrepreneurship, increasing the efficiency of monetary policies that are in the first level.

Research limitations/implications
Research limitations include access to upstream documents, strategies, administrative and organizational coordination to study documents.

Practical implications
These findings are very important to scholars, the policymakers and technological entrepreneurship operators in designing their financing strategies. The results show that the most important factors influencing financing and entrepreneurship in Iran are increasing the productivity of goods and services, supporting entrepreneurship, increasing the efficiency of monetary policies.

Originality/value
To the best of the author’s knowledge, this is the first study to explore the explanation and classification of technology-based entrepreneurship financing policies in Iran. Moreover, the findings of this study would prove useful in detailed studies of financing policies in the Middle Eastern countries as well.

Published: March 2022

Purpose
This exploratory study aims to explore the Pakhtun pregnant women’s experiences/issues during the COVID-19 pandemic.

Design/methodology/approach
This research is based on interviews.

Findings
This research found that plummeting medical services pose not only serious health risks to the Pakhtun women in Khyber Pakhtunkhwa (KP) but expose them to social and cultural challenges resulting in severe mental health issues. This study also found that the policies adopted by the Government of Pakistan for tackling COVID-19 completely threw off track basic health services that both men and women require in times of health emergencies.

Originality/value
This paper is 100% original research based on an exploratory study.
Comparing IT and non-IT firms in corporate social responsibility and financial context for attracting and retaining employees
Authors: Lo Janice , Lam Monica , Wei Sijing 
Published: March 2022

PurposeThe purpose of this paper is to investigate how information technology (IT) firms are different from non-IT firms in terms of corporate social responsibility and financial variables for attracting and retaining employees.Design/methodology/approachThrough logit regression models, the authors used corporate social responsibility and financial variables to examine the differences between 512 Fortune’s Best Companies to Work For and a random sample of 512 Non-Best Companies peer firms.FindingsThe analysis results show that IT firms are stronger in terms of research and development spending, return on assets, Tobin’s q and leverage conditions, as well as employee relations and environmental performance in corporate social responsibility. Moreover, for IT firms, innovativeness (characterized by high research and development expenditures) is by far the strongest predictor of whether a company is selected to be on the Best Companies to Work For list.Research limitations/implicationsThis research demonstrated a hybrid, multifaceted research design using different analysis tools to explore new factors of a research topic. The results confirm the associations among variables, which may not represent causal relationships.Practical implicationsThe results shed light on the relationship between corporate social responsibility/finance and IT employee turnover, which provides another dimension for management’s consideration beyond the classic psychometric/fringe benefit analysis for examining employee turnover.Social implicationsIT firms’ superior ability to attract and retain employees using their innovativeness may impact the general public’s career planning and training decisions.Originality/valueThis research project integrated data from four different sources and investigated the IT employee turnover issue from the organizational level rather than the individual employee level.

Published: March 2022

PurposeThe purpose of this paper is to examine the influence of export logistics components: shipment arrangements, timely delivery, customs quality, trade infrastructure, and tracking and tracing on export competitiveness of firms in the East African Community (EAC).Design/methodology/approachThe study adopted the Structural Gravity Model and the Poisson pseudo-maximum likelihood (PPML). PPML a nonlinear estimation method was applied in STATA on a balanced panel data for the period of 2007–2018. Data were obtained from World Bank International Trade Centre (ITC), World Bank Logistics Performance Index (LPI) and World Bank development indicators.FindingsResults show that timely delivery and tracking and tracing of exports are positive and significant predictors of export competitiveness in EAC countries. Conversely, shipment arrangements, customs quality and trade infrastructure have no influence on export competitiveness.Research limitations/implicationsThe results of this study show that export logistics components of shipment arrangements, customs quality and trade infrastructure do not matter at the present in improving export competitiveness in the EAC. There is a need to examine the intricate nature of the EAC economy to further this study's findings.Practical implicationsThe EAC partner states should embrace deep integration by removing the behind the border trade barriers in addition to other trade restrictions, to create a common economic space among member states. This will further shrink the delivery time and the tracking and tracing of exports hence improving the competitiveness of EAC exports within the region and outside. Also, common and harmonized trade policies and regulations should be implemented through mutual recognition agreements where countries agree to recognize one another's conformity assessments.Originality/valueThis study explains the complex dynamic interactions of export logistics factors in the EAC using quantitative data and that this interaction has an effect on the export competitiveness in import-dominated countries with less harmonization in their trade policies.

AbstractObjectiveTo evaluate the effectiveness of feedback reports and feedback reports + external facilitation on completion of life‐sustaining treatment (LST) note the template and durable medical orders. This quality improvement program supported the national roll‐out of the Veterans Health Administration (VA) LST Decisions Initiative (LSTDI), which aims to ensure that seriously‐ill veterans have care goals and LST decisions elicited and documented.Data SourcesPrimary data from national databases for VA nursing homes (called Community Living Centers [CLCs]) from 2018 to 2020.Study DesignIn one project, we distributed monthly feedback reports summarizing LST template completion rates to 12 sites as the sole implementation strategy. In the second involving five sites, we distributed similar feedback reports and provided robust external facilitation, which included coaching, education, and learning collaboratives. For each project, principal component analyses matched intervention to comparison sites, and interrupted time series/segmented regression analyses evaluated the differences in LSTDI template completion rates between intervention and comparison sites.Data Collection MethodsData were extracted from national databases in addition to interviews and surveys in a mixed‐methods process evaluation.Principal FindingsLSTDI template completion rose from 0% to about 80% throughout the study period in both projects' intervention and comparison CLCs. There were small but statistically significant differences for feedback reports alone (comparison sites performed better, coefficient estimate 3.48, standard error 0.99 for the difference between groups in change in trend) and feedback reports + external facilitation (intervention sites performed better, coefficient estimate −2.38, standard error 0.72).ConclusionsFeedback reports + external facilitation was associated with a small but statistically significant improvement in outcomes compared with comparison sites. The large increases in completion rates are likely due to the well‐planned national roll‐out of the LSTDI. This finding suggests that when dissemination and support for widespread implementation are present and system‐mandated, significant enhancements in the adoption of evidence‐based practices may require more intensive support.

Published: March 2022

AbstractFabry disease (FD) manifests decreased α‐galactosidase A (α‐Gal A) activity and multiorgan damage. There are some undiagnosed cases of the condition among patients on dialysis. The prevalence of FD may also vary with the region. Among 227 male patients undergoing maintenance hemodialysis in Awaji Island, a remote island in Japan, 201 (88.5%) were included in this study. Patients with α‐Gal A activity <5.0 pmol/h/disk proceeded to secondary screening. Patients with positive secondary screening underwent further genetic analysis. The number of patients with a family history of cardiac, cerebrovascular, and kidney diseases was 31 (15.4%), 23 (11.4%), and 31 (15.4%) patients, respectively. Although three patients (1.5%) had low α‐Gal A activity, none of them was positive in the secondary screening. We could not identify any male hemodialysis patient with FD in Awaji Island, even though some patients had a family history of kidney and cardiovascular diseases.

SummaryThe immune system can influence cancer development by both impeding and/or facilitating tumour growth and spread. A better understanding of this complex relationship is fundamental to optimise current and future cancer therapeutic strategies. Although typically regarded as a localised and immunosuppressive anti‐cancer treatment modality, radiation therapy has been associated with generating profound systemic effects beyond the intended target volume. These systemic effects are immune‐driven suggesting radiation therapy can enhance anti‐tumour immunosurveillance in some instances. In this review, we summarise how radiation therapy can positively and negatively affect local and systemic anti‐tumour immune responses, how co‐administration of immunotherapy with radiation therapy may help promote anti‐tumour immunity, and how the use of immune biomarkers may help steer radiation therapy‐immunotherapy personalisation to optimise clinical outcomes.

AbstractSarcopenia is one of the main factors contributing to the disability of aged people. Among the possible molecular determinants of sarcopenia, increasing evidences suggest that chronic inflammation contributes to its development. However, a key unresolved question is the nature of the factors that drive inflammation during aging and that participate in the development of sarcopenia. In this regard, mitochondrial dysfunction and alterations in mitophagy induce inflammatory responses in a wide range of cells and tissues. However, whether accumulation of damaged mitochondria (MIT) in muscle could trigger inflammation in the context of aging is still unknown. Here, we demonstrate that BCL2 interacting protein 3 (BNIP3) plays a key role in the control of mitochondrial and lysosomal homeostasis, and mitigates muscle inflammation and atrophy during aging. We show that muscle BNIP3 expression increases during aging in mice and in some humans. BNIP3 deficiency alters mitochondrial function, decreases mitophagic flux and, surprisingly, induces lysosomal dysfunction, leading to an upregulation of Toll‐like receptor 9 (TLR9)‐dependent inflammation and activation of the NLRP3 (nucleotide‐binding oligomerization domain (NOD)‐, leucine‐rich repeat (LRR)‐, and pyrin domain‐containing protein 3) inflammasome in muscle cells and mouse muscle. Importantly, downregulation of muscle BNIP3 in aged mice exacerbates inflammation and muscle atrophy, and high BNIP3 expression in aged human subjects associates with a low inflammatory profile, suggesting a protective role for BNIP3 against age‐induced muscle inflammation in mice and humans. Taken together, our data allow us to propose a new adaptive mechanism involving the mitophagy protein BNIP3, which links mitochondrial and lysosomal homeostasis with inflammation and is key to maintaining muscle health during aging.

Published: March 2022

AbstractRegenerative endodontic treatment (RET) may not be suitable in some necrotic young permanent molars due to coexistent roots with closed and open apices, and/or inadequate apical bleeding in one or more roots. Here, we present a combined treatment approach utilising conventional root canal treatment in the closed‐apex roots and RET on the open‐apex roots of necrotic young molars. The closed‐apex roots of 8 molars received root fillings, and their open‐apex roots were treated with a regenerative endodontic procedure. In another molar, the failed RET on one root was retreated by conventional root canal filling, preserving other revitalised roots. After 4–6 years, all teeth showed periapical healing in the absence of clinical symptoms. The combined conventional and regenerative treatment approach can yield favourable healing outcomes in necrotic, young molar roots with different levels of apical closure. Likewise, failed revitalised roots can be retreated separately with conventional root filling.
Ethics of U.S. government policy responses to the COVID‐19 pandemic: A utilitarianism perspective
Authors: Herron Terri L. , Manuel Timothy 
Published: March 2022

AbstractCOVID‐19 hit the United States in January 2020, quickly resulting in stay‐at‐home orders that sent the U.S. economy into a major recession. The federal government leveraged fiscal, regulatory, and monetary policies to provide relief. Decisions had to be made in a complex environment wrought with difficult choices, complicated by the federalist governing system in the United States. Myers (2016, p. 202) asserted, “If an event like the [1918 influenza] pandemic were to occur in the United States, it is important that the government be prepared, not only in terms of material, but ethically.” We analyze the ethical choices of the initial responses by reviewing early U.S. government responses and the impact of culture, federalism, and justice. We conclude that utilitarian analyses of balancing infection rates and economic impacts must be supplemented with Kantian principles of not treating people as means to an end, balancing the protection of individual freedoms with the good of society, and protecting vulnerable groups. As governments prepare for future crises, ethical considerations should be built into those plans as guardrails to guide decision‐makers.

SUMMARYThe ideal duration of anticoagulation therapy in patients with autoimmune disorders and venous thromboembolism (VTE) is controversial. We used the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) database to compare the incidence rate of major bleeding during anticoagulation versus the incidence rate of VTE recurrences after its discontinuation. We included 1061 patients with autoimmune disorders and VTE followed‐up after discontinuing anticoagulant therapy: rheumatoid arthritis, 321; polymyalgia rheumatica, 159; ulcerative colitis, 134; Crohn’s disease, 111; systemic lupus erythematosus (SLE), 82; giant cell arteritis, 58; ankylosing spondylitis, 39; Behcet disease, 17; other vasculitides, 140. During anticoagulation (median, 183 days), 64 patients had major bleeding. After discontinuing anticoagulation (median, 190 days), 112 patients developed symptomatic VTE recurrences. In most subgroups, the incidence rate of major bleeding during therapy was similar to the incidence rate of VTE recurrences after its discontinuation. However, in patients with SLE (10.0 major bleeds, 95% confidence interval [CI] 4.07–20.9) per 100 patient‐years vs. 3.62 VTE recurrences, 95% CI 1.15–8.74) or ankylosing spondylitis (10.9 major bleeds [95% CI 3.47–26.3] vs. 4.69 VTE recurrences, 95% CI 1.19–12.8) the incidence rates of major bleeding during anticoagulation were over twofold higher than the incidence rates of VTE recurrences after its discontinuation.
