Data Ecosystem Business Models
Authors: D'Hauwers Ruben , Walravens Nils , Ballon Pieter
Published: November 2022

Purpose: Organizations evolve from using and governing data internally towards the exchange of data in multi-organizational data ecosystems. The purpose of this research is to determine a business model framework for actors operating in and/or entering a data ecosystem.
Methodology: To determine a business model framework in data ecosystems. an analysis was made based on how the research fields of “business models”, “data governance”, “data ecosystems”, “data sharing”, “business ecosystem” complement each other. A business model framework was created, which was applied to three use case studies in the field of Smart Cities and Urban Digital Twins: The Helsinki Digital Twin, the Rotterdam Digital Twin, and the Smart Retail Dashboard in Flanders.
Findings: The business model of actors in a data ecosystem is determined by value and control factors. Value is determined by the capability to create value through the exchange of data in the ecosystem, and to capture value through revenue (sharing) models and cost (sharing) models. Control is determined by ecosystem control. Governance models on the ecosystem level are required to enable the collaboration and to ensure trust to allow for the willingness to share data. Additionally, data governance on an ecosystem level is required, enabling the data exchange between the actors.
Research Limitations: The model was applied to three use cases in Smart Cities and Urban Digital Twins. Consequently, the data ecosystems concern a high presence of public actors, yet also includes private companies. The applicability needs to be identified in other sectors in further research. Additionally, as the scope of the study was on business models, data governance, data-sharing and data ecosystems, abstraction was made of fields of study beyond these topics.
Value and practical implications: The Data Ecosystem Business Model framework can serve as a guideline for organizations entering a data ecosystem, as well as for actors aiming to establish novel data ecosystems. Additionally, the framework can serve as a high-level overview for further research into the field of business models in data ecosystems.

Bambara groundnut (Vigna subterranean L. Verdc) is a leguminous plant and its seeds are highly nutritious and can be considered as complete food. In addition to being a neglected crop; its production is limited by several constraints among which virus diseases are the most implicated. In order to contribute to the improvement of bambara groundnut in Nigeria, landraces of bambara groundnut were screened for resistance to Cucumber mosaic virus (CMV), one of the most damaging viruses in grain legumes. Treatments consisted of five landraces namely Black, Brown, Cream, Red nav, and Zebra coloured got from local farmers. These were arranged in Randomised Complete Block Design, with three replicates. Seedlings were infected with CMV isolate three weeks after sowing (WAS), during the 2019 and 2020 trials. The infected plants exhibited various symptoms of chlorosis, leaf deformation, growth retardation, and plant stunting. The sCMV caused significant reduction in plant height, the number of branches, leaves, pods, and seeds weight. In the 2019 and 2020 trials, 100 % incidence with the highest severity was observed in the Bambara groundnut landraces. Disease incidence varied between 41.6% in “Black” and 95.8 % in “Cream,” while disease severity was higher in “Cream” and “Red nav” with 5.0 respectively. “Black” and “Zebra” were the tallest with 16.8 cm among the infected as well as disease-free with 22.6 cm tall plants. “Black” landrace produced the highest number of pods in both CMV infections with 21 and disease-free with 33 pods respectively. Conversely, the number of days to flowering of 43 days was highest in infected plants of “Black”. The “Black” and “Zebra” landraces recorded uniform seed weights and the highest seed weight under CMV infection with 1.7 g per plant. The impact of the virus on yield loss was lowest in “Black” and “Zebra” landraces which indicated their possible use in the management of Cucumber mosaic virus disease in Bambara groundnut.

The Covid-19 pandemic has posed a global threat to public health. In terms of affecting the systemic health, it has also created an impact on the ocular health of people. The scenario of work from home, long hours of online classes for students, has led to increase in incidences of refractive error. From affecting visual acuity, it has also posed increased risk of increasing the degree of myopia. Even in these cases a patient may have a best corrected visual acuity of 6/6 but he or she may not be satisfied due to improper contrast sensitivity. This study was done to compare contrast sensitivity functions in myopic patients by assessing and comparing various parameters such as demographic factors, age, sex and profession. We included 500 myopic patients with a best corrected visual acuity of 6/6, without any retinal pathology. Contrast sensitivity functions were compared with astigmatism, degree and duration of myopia and with duration of use of spectacles. All three age groups showed mild decline in contrast sensitivity but majority consisted of the under-30 age group with 233 cases (46.6%). Females being in majority (78.1%) had mild decrease in contrast sensitivity. We recorded the profession of each patient and observed that there was mild decline in contrast sensitivity in all professions, and 79.2% of the total students showed mild decrease in contrast sensitivity, which can be attributed to long hours of screen time in lockdown phase. Low myopia of less than 3D had mild decline in contrast sensitivity (88.4%), whereas severe decline in contrast sensitivity was seen in high myopics (11.9%), which was directly co-related with degree of myopia. Astigmatism also showed mild decline in contrast sensitivity, which was 78.5% in compound myopic astigmatism and 88.5% in simple myopic astigmatism. We found severe decline in contrast sensitivity only in 2.4% of myopic patients with a duration of less than 12 months. The rest of the patients had mild decline in contrast sensitivity. This validates that contrast sensitivity has an impact on all parameters of the study such as age, gender, profession, duration, degree of myopia and astigmatism.

Central serous chorioretinopathy (CSCR) is a disease involving leakage of serous fluid through the retinal pigment epithelium, resulting in neurosensory retinal detachment. The majority of acute CSCR cases resolve spontaneously. However, treatment options for chronic and recurrent cases are lacking. In this case series, topical nepafenac 0.1% and 0.3% were investigated as novel treatments for chronic and recurrent CSCR. We performed a retrospective case series analysis of six patients diagnosed with chronic recurrent CSCR. Data from patient medical records were collected, including age range, gender, subjective complaints, Snellen visual acuity (VA), clinical eye examination, central macular thickness (CMT) on optical coherence tomography, prior treatments, time of follow-up, and time to resolution of CSCR. The six cases of chronic and recurrent CSCR in this study were treated with 0.1% and/or 0.3% topical nepafenac. The mean age of the six cases was 52 years. There was an average gain in vision of 2.5 lines in Snellen VA, and a final Snellen VA of 20/20 was achieved in each case. The average time to complete resolution of CSCR was 3.33 months. The decrease in CMT ranged from 105 µm to 507 µm, with an average decrease of 240 µm, and subretinal fluid resolved completely in all the six cases.

Published: November 2022

The crowd context-based learning process via IoT wearable technology [IoTW-driven Crowd context-based learning (CCBL)] is a new learning paradigm that integrates Technological Cybergogical Content Knowledge (TCACK) based on connectivism, cognitive tools and information processing theories to promote digital health literacy. In this study, the IoTW-driven CCBL was designed by incorporating content, cybergogical, and technological elements, which can become a sustainable solution in educational settings during the global COVID-19 pandemic. The researchers collected qualitative data by confirmatory focus groups from 12 experts who hold doctoral degrees or equivalent and have at least 3 years of relevant experience. The results of these studies found that the IoTW-driven CCBL involves three specific learning contents (healthcare, disease prevention and health promotion); five dynamic learning steps (context-aware alerting step; observing and questioning step; social information-seeking step; action step; and self-reflection step as all cognitive tools embedded in IoTW devices help promote all digital health literacy components); and four cognitive tools (notification tool; communication tool; searching tool; and monitoring tool). The IoTW-driven CCBL will allow learners to respond to real-life situations by utilising IoT devices to access, apprehend, appraise and apply health information from digital technologies in daily life for well-being, especially in educational settings.

Published: November 2022

This research examined happiness with online learning among 2,190 undergraduate students at Suan Dusit University (SDU), who studied online in the first semester of the 2021 academic year. The data were collected from online happiness assessment forms completed by the SDU students. Frequencies, percentages, means, and standard deviations were calculated, and t-tests and one-way ANOVA were performed to analyze the data. The results indicated that students’ overall happiness with their online learning was at a moderate level. The students were also satisfied with their studies at a moderate level. They were also moderately proud of the university and were comfortable with online learning, especially regarding the instructors, online instruction, the instructional activities, and lesson content. Students of different genders all enjoyed learning with the online instructional system, as arranged by SDU, at the same level. However, students from different majors, different years, different faculties or schools, different learning campuses or centers, and with different average monthly allowances, enjoyed their online learning at SDU differently.
Revolutionising the Accounting Curriculum in Higher Education: A vision of the future
Authors: Sangster Alan
Published: November 2022

Experiences of teaching since Covid first led to campuses closing worldwide inMarch 2020 highlighted problems in how accounting is taught and assessed.Those problems threaten the integrity of the education process and the qualityof future accounting graduates. This paper considers the pressures these factorsplace on accounting faculty and proposes measures to adopt to address them.It also addresses the recognised problem that accounting programmes do notproduce graduates appropriately equipped for a career as accountants, especiallynow that technology is causing the nature of entry-level positions, and soalso those above them, to change. In response, it proposes how accountingprogrammes may be redesigned to produce graduates equipped to both meet thedemands of employers and develop careers that respond to the rapidly changingrole of accountants. In doing so, it proposes major changes to how accounting istaught in universities, to its assessment, its curriculum, to faculty recruitmentand training and, where relevant, to accreditation of accounting programmes byprofessional accountancy bodies.
Determination of Physical and Mechanical Properties of Waste Paper Boards Supported by Wood Chips and Chopped E-glass Fiber
Authors: Sözen Eser
Published: November 2022

Today, legal regulations, along with social awareness, have made waste management a necessity. Depending on the type of waste, technological developments have enabled an increase in the number of approaches, e.g., reusing, recycling, and manufacturing of different products. In this study, low-density boards were produced using different proportions of office waste paper, wood chips, and chopped E-glass fiber. Waste paper and glass fiber formed the middle layer of the boards and wood chips comprised the surface layers. The density, water absorption, and thickness swelling properties of the boards were investigated. Among the mechanical properties, the modulus of rupture, modulus of elasticity, and internal bond strength were determined. The use of wastepaper led to a reduction in the modulus of rupture and modulus of elasticity of the boards. An increase in the glass fiber ratio contributed positively to the water absorption and thickness swelling properties, whereas it directly led to decreases in the internal bond strength, and the modulus of rupture and modulus of elasticity values. Nonetheless, the low-density boards were able to meet the minimum modulus of rupture and modulus of elasticity specified in ANSI 208.1 standards, while only one variation met the IB requirements.
A Linear Time Algorithm for Computing Longest Paths in Cactus Graphs
Authors: Markov Minko , Andreica Mugurel , Manev Krassimir , Tapus Nicolae
Published: November 2022

We propose an algorithm that computes the length of a longest path in a cactus graph. Our algorithm can easily be modified to output a longest path as well or to solve the problem on cacti with edge or vertex weights. The algorithm works on rooted cacti and assigns to each vertex a two-number label, the first number being the desired parameter of the subcactus rooted at that vertex. The algorithm applies the divide-and-conquer approach and computes the label of each vertex from the labels of its children. The time complexity of our algorithm is linear in the number of vertices, thus improving the previously best quadratic time algorithm.
An Algorithmic Approach to Inferring Cross-Ontology Links while Mapping Anatomical Ontologies
Authors: Petrov Peter , Krachounov Milko , Van Ophuizen Ernest A. A. , Vassilev Dimitar
Published: November 2022

Automated and semi-automated mapping and the subsequently merging of two (or more) anatomical ontologies can be achieved by (at least) two direct procedures. The first concerns syntactic matching between the terms of the two ontologies; in this paper, we call this direct matching (DM). It relies on identities between the terms of the two input ontologies in order to establish cross-ontology links between them. The second involves consulting one or more external knowledge sources and utilizing the information available in them, thus providing additional information as to how terms (concepts) from the two input ontologies are related/linked to each other. Each of the two ontologies is aligned to an external knowledge source and links representing synonymy, is-a parent-child, and part-of parent-child relations, are drawn between the ontology and the knowledge source. These links are then run through a set of simple logical rules in order to come up with cross-ontology links between the two input ontologies. This method is known as semantic matching. It proves useful and reasonably accurate; in this paper, we call it the source matching predictions (SMP) procedure.Not all cross-ontology links that semantically (i.e., from a biological/anatomical standpoint) exist between the two input ontologies will be discovered by either DM or SMP. To improve the discovery of cross-ontology links we propose a novel algorithmic procedure which involves a probability-like scoring scheme. This procedure is called the child matching predictions (CMP) procedure. Describing the DM, SMP, CMP procedures, and particularly the CMP procedure in formal terms is the main goal of this paper.

Let G1 = (V1, E1) and G2 = (V2, E2) be two graphs having a distinguished or root vertex, labeled 0. The hierarchical product G2 ⊓ G1 of G2 and G1 is a graph with vertex set V2 × V1. Two vertices y2y1 and x2x1 are adjacent if and only if y1x1 ∈ E1 and y2 = x2; or y2x2 ∈ E2 and y1 = x1 = 0. In this paper, the Wiener, eccentric connectivity and Zagreb indices of this new operation of graphs are computed. As an application, these topological indices for a class of alkanes are computed.

Published: November 2022

The correlated probit model is frequently used for multiple ordered data since it allows to incorporate seamlessly different correlation structures. The estimation of the probit model parameters based on direct maximization of the limited information maximum likelihood is a numerically intensive procedure. We propose an extension of the EM algorithm for obtaining maximum likelihood estimates for a correlated probit model for multiple ordinal outcomes. The algorithm is implemented in the free software environment for statistical computing and graphics R. We present two simulation studies to examine the performance of the developed algorithm. We apply the model to data on 121 women with cervical or endometrial cancer. Patients developed normal tissue reactions as a result of post-operative external beam pelvic radiotherapy. In this work we focused on modeling the effects of a genetic factor on early skin and early urogenital tissue reactions and on assessing the strength of association between the two types of reactions. We established that there was an association between skin reactions and polymorphism XRCC3 codon 241 (C>T) (rs861539) and that skin and urogenital reactions were positively correlated.ACM Computing Classification System (1998): G.3.

In this paper a Variable Neighborhood Search (VNS) algorithm for solving the Capacitated Single Allocation Hub Location Problem(CSAHLP) is presented. CSAHLP consists of two subproblems; the first ischoosing a set of hubs from all nodes in a network, while the other comprises finding the optimal allocation of non-hubs to hubs when a set of hubsis already known. The VNS algorithm was used for the first subproblem,while the CPLEX solver was used for the second. Computational resultsdemonstrate that the proposed algorithm has reached optimal solutions onall 20 test instances for which optimal solutions are known, and this in shortcomputational time.

Fragmento

La Independencia de nuestra Patria, como tal, no se limita ni al grito de independencia del 20 de julio de 1810, ni a la gesta libertadora, ni a la gloriosa vitoria del Puente de Boyacá. Es en realidad un extenso período de tiempo que parte de la Revolución de Los Comuneros en el Nuevo Reino de Granada, que tuvo su iniciación en la población del Socorro, Santander, el día 16 del mes de marzo de 1781, cuando Manuela Beltrán rompió el edicto virreinal referente a las nuevas contribuciones al grito de “viva el Rey y muera el mal gobierno”. La Independencia pasa también por la publicación de los “Derechos del Hombre” por don Antonio Nariño y Álvarez del Casal a comienzos del año de 1794, quien fue inmensamente ilustrado en las ciencias médicas de la época -prácticamente un galeno-, lo que puso en aprietos al Doctor Juan Gualberto Gutiérrez, su médico tratante durante sus últimos 5 días de vida en la Villa de Leyva. Siguiendo con las enseñanzas del Sabio gaditano don José Celestino Mutis, médico, cirujano, botánico y Sacerdote, llegado en 1761 a la Ciudad de Santa Fe de Bogotá quien, paradójicamente, a pesar de ser totalmente fiel al Soberano español, sembró, con sus enseñanzas de matemáticas, de botánica, la llama de la libertad en las mentes brillantes de don Francisco José de Caldas y sus compañeros en el seno de la Expedición Botánica del Nuevo Reino de Granada. Es así como, de las enseñanzas de un gran médico gaditano, español hasta la médula de los huesos, surge la llama de la libertad en estas tierras.

La paleo-oncología es el estudio de carcinomas y sarcomas en animales, poblaciones humanas antiguas y sus precursores homínidos. Estas poblaciones resultan informativas sobre las posibles influencias en el cáncer de la evolución morfológica y funcional, la dieta, el estilo de vida y otros factores ambientales. La prevalencia del cáncer en poblaciones antiguas podría haber diferido de la de los humanos modernos, debido a diferencias sustanciales en la exposición a agresores externos, por el envejecimiento, y la disponibilidad de las intervenciones terapéuticas contemporáneas. Los datos físicos disponibles sobre el cáncer en la antigüedad incluyen la evidencia de su existencia en fósiles de animales y humanos, y en sus precursores. Las dificultades de la investigación paleo-oncológica incluyen un registro tisular limitado. Al evaluar el cáncer en restos antiguos, también se debe abordar el problema de la pseudopatología, en la que un cambio tisular observado puede representar una lesión tumoral antemortem o un artefacto postmortem. Los descubrimientos arqueológicos futuros y la aplicación de técnicas de diagnóstico mejoradas pueden permitir que la paleo-oncología proporcione contribuciones a nuestra comprensión actual del cáncer.

Published: November 2022

Background: In thoracic surgeries requiring thoracotomy incisions, correct positioning of the double-lumen endotracheal tube (DLT) is mandatory. After the pandemic of novel COVID-19, using simple, noninvasive technology such as lung ultrasound (LUS) can be important in avoiding the possibility of spreading infectious diseases or contagious infections that can follow using fiberoptic bronchoscopy (FOB). Objectives: We aimed to assess the accuracy of auscultation and LUS in relation to FOB in the assessment of DLT placement and to identify the possibility of using LUS as an alternative to FOB during DLT insertion. Methods: This diagnostic accuracy study was conducted according to STARD guidelines; enrolled 120 cases requiring DLT intubation. After DLT insertion, all patients were examined by stethoscope, then by LUS for determination of DLT position, and then confirmed by FOB in the same patient. Results: Three patients dropped out due to failed intubation, and only 117 cases were analyzed. Time was significantly longer for LUS than for auscultation and FOB and was insignificantly different between auscultation and FOB. Auscultation had 76.14% sensitivity, 34.48% specificity, and 65.81% accuracy in the determination of correct DLT placement. LUS had 92.05% sensitivity, 79.31% specificity, and 88.89% accuracy in detecting correct DLT placement. There was substantial agreement between LUS and FOB (κ = 0.705) and poor agreement between auscultation and FOB (κ = 0.104). Conclusions: LUS can be used as a simple, noninvasive tool for detecting DLT placement with a substantial agreement with FOB.

Published: November 2022

Background: Recent research has focused on the effects of different types of strength training on the performance and body profile of adolescent athletes. However, the effects of short-term plyometric and jump rope training on body profile and athletic performance in adolescent basketball players are a matter of curiosity. Objectives: The aim of this study was to examine the effects of short-term plyometric and jump rope training on body profile and athletic performance in adolescent basketball players. Methods: Twenty-two basketball players aged 13 - 15 were randomly divided into two groups as plyometric (n = 11) and jump rope training group (n = 11). All participants regularly completed to plyometric or jump rope training as 10 units for 4-weeks in addition to basketball training. Somatotype, body composition, push-up & sit-up test, sprint, agility (Illinois & hexagon), jump (vertical, squat, horizontal, plyometric) tests were measured before and end of the study. Results: The push-up (P = 0.049 vs < 0.001), sit-up (P = 0.20 vs < 0.001), squat jump (P = 0.010 vs 0.003) and horizontal jump (P = 0.028 vs 0.014) of the players were significantly increased after 4-weeks plyometric and jump rope training. In addition, plyometric jump (P = 0.007) and hexagon performance (P = 0.001) were significantly increased in jump rope training group. At the end of 4-weeks, body mass, endomorphy and ectomorphy scores of the lower limb plyometric training group, and body mass index, endomorphy & mesomorphy scores and quadriceps circumference of the jump rope training group were significantly increased. Conclusions: Short-term plyometric and jump rope training affect the body profile and athletic performance of the adolescent basketball players, but jump rope training has a more significant effect on athletic performance than plyometric training. Therefore, jump rope training is recommended for coaches who want to gain more athletic performance in a short-term.
A SWOT Analysis of the Experiences of a District Hospital in Ghana During the COVID-19 Pandemic
Authors: Mensah Kofi Tawiah , Asante Akosua Ofosua
Published: November 2022

Background: District-level hospitals in developing countries have unique resource challenges which have been strained by the COVID-19 pandemic and yet, they have been expected to maintain deliverables. The resource restrictions brought about by the COVID-19 pandemic continues to impact the post-pandemic recovery of clinical care in Ghana. Individual institutions now have the uphill task of turning around their fortunes and restoring service quality. Objectives: An assessment, from a strategic management perspective, of how events unfolded at the Agogo Presbyterian Hospital (APH), a secondary centre in Ghana, during the peak of the COVID-19 pandemic could offer useful pointers for the future of healthcare in low-resource settings. Methods: This study reviewed the handling of the COVID-19 pandemic in the Agogo Presbyterian Hospital (APH). Decisions from meetings of the clinical team and the specially constituted ‘COVID-19 task force’ were examined. This information was subjected to a deductive Strength-Weakness-Opportunities-Threats (SWOT) analysis to identify and summarize the major themes emerging. Results: As a strength for APH during the peak of the pandemic, the surgical division defied pandemic projections by recording an increased volume of surgical procedures in 2020. As a key weakness, APH was unable to utilize virtual meeting platforms during the pandemic lockdown period. Regarding opportunities, APH became the beneficiary of relief donations from many first-time partners who were poised to continue this relationship beyond the COVID-19 era. As a threat, the drop in the hospital attendance and the consequent dip in revenue uncovered the dangers of APH’s over-reliance on a single revenue stream. Conclusions: A SWOT analysis of the events in APH during the peak of the COVID-19 pandemic brings into focus the relevant directions in which a district-level hospital needs to channel its limited resources for sustainable benefits that would survive future health crises.

Background: Thyroid hormones play an important role in cardiac tissue function. Therefore, it is important to understand the relationship between thyroid hormone levels and cardiac disorders. Objectives: The present study aimed to assess the relationship between normal serum level of thyroid hormones and left ventricular systolic and diastolic dysfunction. Methods: In this cross sectional descriptive retrospective study, 391 patients were selected. They were referred to the Rajaie Cardiovascular Research Center, Tehran, Iran from 2019 to 2021. After extracting echocardiographic and laboratory data from the clinical records, the parameters affecting the left ventricular systolic and diastolic dysfunction were analyzed using statistical software. Results: The mean age of patients was 41 ± 12.8 years. Among them 58.1% of all patients were female. Tricuspid regurgitation (TR) severity had a significant relationship with thyroid stimulating hormone (TSH) level (P = 0.02). End diastolic interventricular septum thickness (IVSD) was inversely associated with thyroxin4 (T4) level (P = 0.04). Mitral valve inflow deceleration time (MVDT) was inversely correlated with thyroxin3 (T3) (P = 0.04). Left ventricular ejection fraction (LVEF) was inversely related to TSH level and end diastolic right ventricular internal diameter (RVIDd) was directly related to TSH (P = 0.05). Conclusions: Thyroid hormone levels in the normal range can be associated with the tricuspid regurgitation severity, end diastolic right ventricular internal diameter (RVIDd), mitral valve inflow deceleration time (MVDT), and. end diastolic interventricular septum thickness (IVSD). Due to the high prevalence of heart disorders, information on thyroid hormone levels can be helpful in the identification and timely treatment of these disorders.
The 536 Dust Veil Event and the long 6th century
Authors: Gjerpe Lars Erik
Published: November 2022

When Bo Gräslund (2008) argued that two years without summer in the late 530s was the reality behind the Fimbulwinter myth, it became acceptable once again to blame the climate and weather for radical societal changes. In the years since the 2008 article, the Dust Veil Event seems to have caused every 6th century change, even though a few critics have raised their voices against these interpretations. Recently, several authors have highlighted datasets that do not work with monocausal interpretation, and this critique has gained support. This leads to the fundamental question: how – if at all – did the Dust Veil Event affect  Scandinavian societies? And following this: what methodology can we use to explore such an intricate problem? As disasters are inherently social phenomena, climatic change results in disaster only if societal circumstances allow. I will argue that resilience theory stands out as a promising approach, as it inherently considers the impact of nature as well as human agency, making the characteristics of the society stricken by disaster is as important as the disaster itself. Moreover, as the dating of the archaeological inventory is not accurate enough to relate material change to a single calendar year (such as AD 536), investigators need a long-term view. It is also necessary to consider circumstances such as long-term societal change and the geopolitical situation in Europe, and its impact on Scandinavia.
