Impacts of the All-Sky Assimilation of FY-3C and FY-3D MWHS-2 Radiances on Analyses and Forecasts of Typhoon Hagupit
Authors: Chen Keyi , Chen Zhenxuan , Xian Zhipeng , Li Guancheng
Published: April 2023

With the Microwave Humidity Sounder-2 (MWHS-2)/Fengyun (FY)-3D in operation, this is the first study to evaluate the impact of a joint assimilation of MWHS-2 radiances under all-sky conditions from both the FY-3C and FY-3D satellites on typhoon forecasting within regional areas. In this study, Typhoon Hagupit in 2020 was chosen to investigate the impacts of assimilating MWHS-2 radiances; the forecasting performances of the joint assimilation method were slightly better than the experiments assimilating MWHS-2 observations from FY-3C or FY-3D only, and the results of the latter two experiments were comparable, especially in terms of the landfall location of Hagupit. With additional assimilated cloud- and precipitation-affected MWHS-2 observations, improved typhoon track and intensity forecasts as well as forecasts of the precipitation caused by Hagupit were achieved due to the improved analyses of relative humidity, temperature and wind fields around Hagupit compared to the clear-sky assimilation experiments. In addition, the channel-selection scheme evidently affected the forecasting performance; that is, the radiances from the MWHS-2 118 GHz and 183 GHz channels provided opposite results in terms of the Hagupit track, and this finding needs further investigation in the future.

Published: April 2023

The flowrate measurement of the gas–liquid two-phase flow frequently observed in industrial equipment, such as in heat exchangers and reactors, is critical to enable the precise monitoring and operation of the equipment. Furthermore, certain applications, such as oil and natural gas processing plants, require the accurate measurements of the flowrates of each phase simultaneously. This study presents a method that can simultaneously measure the volumetric flowrates of each phase of gas and liquid two-phase mixtures, Qg and Ql, respectively, without separating the phases. The method employs a turbine flowmeter and two pressure sensors connected to the pipes upstream and downstream of the turbine flowmeter. By measuring the rotational speed of the rotor and the pressure loss across the flowmeter, the flowrate of the two-phase mixtures Qtp = (Qg + Ql) and the gas volumetric flowrate ratio β = (Qg/Qtp) are determined. The values of Qg and Ql are calculated as βQtp and (1 − β)Qtp. This study also investigates the measurement accuracies for air–water two-phase flows at 0.67 × 10−3 ≤ Qtp ≤ 1.67 × 10−3 m3/s and β ≤ 0.1, concluding that the full-scale accuracies of Qtp, β, Qg, and Ql are 3.1%, 4.8%, 3.9%, and 3%, respectively. These accuracies either match or improve the accuracies of similar methods reported in the literature, indicating that the proposed method is a viable solution for the determination of phase-specific flowrates in gas–liquid two-phase mixtures.

Published: April 2023

The ecological crisis that emerged rapidly in the 2000s because of vertiginous economic growth is still one of the dominant themes today. This unprecedented phenomenon has led to intense political-economic and social tensions over reconsidering the priorities of “post-industrial capitalism”. The main issues here are increasing inequalities in the distribution of resources and high dependence on non-renewable energies. In response, valuable policies have been developed with the intention of creating new economic models that satisfy environmental and ecological needs. However, the literature shows that the effectiveness of the global schemes proposed to achieve sustainable behaviors and techniques has been very low. In the hospitality sector, particularly in the food and beverage department, pollution and consumption of scarce resources remain issues. In this paper, we propose a structural framework for analyzing the commitment of hotels regarding sustainable practices in the F&B department, centered on standards set by relevant institutions. To enhance understanding, an extension of the theory of planned behavior (TPB) is proposed. The use of this conceptual framework will enable us firstly to gain a perception of how a hotel acts through its F&B administrator in the light of relevant standard practices. Secondly, it will allow us to understand the role of the common internal and external factors behind the theories describing the behavior adopted. In this way, this research aims to contribute to a global understanding of the factors that influence the commitment of hotels to sustainable practices in their F&B department.
Refined Simulation Study on the Effect of Scour Environments on Local Scour of Tandem Bridge Piers
Authors: Gao Pengcheng , Mou Xianyou , Ji Honglan
Published: April 2023

Ice cover is a natural phenomenon unique to rivers in cold regions, and its existence is one of the reasons for the collapse of structural foundations of bridge piers across rivers. In order to understand the influence of different scouring environments on the hydrodynamics and sand bed morphology in the local scour holes around bridge pier foundations, this paper simulates the dynamic evolution process of the local scouring of tandem combination piers under open-flow and ice-cover environments, based on a turbulence model using the Reynolds-averaged Navier Stokes (RANS) method and a sediment transport model considering the slope collapse effect, respectively. This study also takes the vortex flow and shear stress distribution at different characteristic moments of the pier perimeter section as the penetration point to analyze the effect of the influence law of the scouring environment on the morphology and relative time scale of the scour hole, and makes a detailed comparison with the results of the indoor flume test. The results of this study show that: for local scouring in open-flow conditions, sediment initiation is doubly inhibited and the hydrodynamic forces in the scouring hole are weakened; the local scouring caused by ice cover contributes to the total scouring of the submerged pier within its coverage area, which significantly increases the depth and range of the local scouring hole; and, although the interaction of turbulent eddies and shear stress on the pier side is the main dynamic mechanism of the scouring generated around the pier, the two have a strong correlation. The results of this study, obtained by accurately quantifying the amount of eddies and shear stress around the pier, are the basis for the reasonable estimation of the maximum local scouring depth, which can provide a reference for the study of the evolution of the riverbed around submerged structures in cold areas and is essential to avoid structural damage to the piers and reduce the economic loss of traffic..
Sustainability of Heritage Villages through Eco-Tourism Investment (Case Study: Al-Khabra Village, Saudi Arabia)
Authors: Altassan Abdulrahman
Published: April 2023

This study explores the reasons for the failure to sustain the rehabilitation of Al-Khabra as a heritage village for tourism. Despite the rehabilitation activities since 2007 and the comprehensive plans for the development, protection, and operation of the village, tourism activities are limited due to the restricted availability of qualified buildings, infrastructure, and services. This has made the investment in the village economically unviable. This study aims to propose sustainability strategies for heritage villages by investing in eco-tourism. This study used a qualitative descriptive approach by analyzing the rehabilitation experience through available reports and studies, field observations, and interviews. A holistic and environmental approach was proposed based on the integration of cultural and environmental elements to promote eco-tourism in the village. This study recommends the development of national policies that regulate the preservation of local resources and biodiversity within an integrated framework that enhances the unique environmental advantages of the village and encourages investment in it.

Published: April 2023

In order to study the influence of the cement–tailing ratio and curing age on the mechanical properties of cemented backfill with unclassified tailings and improve the accuracy of the backfill monitoring method, the mechanical characteristics of the failure process of cemented backfill with unclassified tailings at different curing ages were studied using the acoustic emission and infrasound method. The results show that the peak strength and modulus of elasticity of backfill are positively correlated with the curing age. During the failure process of cemented backfill with unclassified tailings, the acoustic emission ringing count shows a “stabilizing–rising–falling–rising” trend, and the infrasonic ringing count will have a “multiple peak” phenomenon. The ib value of the acoustic emission signal generally increases with the extension of the curing age. The ib value of the infrasonic signal generally has a negative correlation with the increase of the curing age. When the ib value of the acoustic emission and infrasonic wave all start to decline in a jumping manner, this indicates that the backfill is about to be damaged. The dominant frequency ratio of acoustic emission signals (FAE) is distributed between 0–4 during the failure process, and the total number of FAE shows the phenomenon of “first decreasing and then increasing” with the curing age. The dominant frequency ratio of infrasonic signals (Fs) is distributed between 0–6. During the failure process of cemented backfill with unclassified tailings, the quantity ratio of class A and B of acoustic emission signals shows a gradually increasing trend, and the quantity ratio of class A and B of infrasonic signals shows a “decreasing–increasing–decreasing” trend, and the quantity ratio of class A and B of acoustic signals shows a sharp increase at the stage of entering the crack’s unstable growth stage.

Published: April 2023

Organizational models for corporate horizontal merger based on partnership, mutual benefit and synergy could act as a driver and a “window of opportunity” for companies seeking to combine the objectives of economic resilience, technological independence and compliance with the environmental, social and governance principles. This article proposes an approach to analyzing the potentials of enterprises and actors in terms of collaboration maturity and evaluation thereof for the potential formation of industrial symbioses and industrial innovation ecosystems. The authors’ proposals have been tested when assessing collaboration maturity of the participants in the industrial symbiosis for phosphogypsum recycling, as well as when assessing collaboration maturity of the actors in Safer Phosphates industrial innovation ecosystem. The development of collaboration between enterprises through an increase in the number of joint innovative technological and environmental projects tends to develop into industrial ecosystems, when knowledge about new produced or promising options for the exchange of resources will be transferred between regional enterprises and attract new actors from other territories and sectors of the economy. Such interaction will provide a long-term development strategy for each actor, and commercial and image benefits will make ecosystem symbiotic interaction a priority for all market participants.

Published: April 2023

As a susceptible demographic, elderly individuals are more prone to risks during sudden disasters. With the exacerbation of aging, new challenges arise for urban disaster reduction and prevention. To address this, the key is to establish a community-scale resilience assessment framework based on the aging background and to summarize factors that influence the resilience level of communities. This approach is a crucial step towards seeking urban disaster prevention and reduction from the bottom up, and serves as an important link to enhance the capacity of urban disaster reduction. This paper explores community resilience evaluation indicators under the background of aging, builds a community resilience evaluation index system based on the Pressure–State–Response, uses the entropy weight method to weigh the indicators, and carries out a resilience evaluation of 507 communities in the main urban area of Changchun. The empirical results indicate significant spatial differentiation of community resilience in the main urban area of Changchun. Moreover, the regional development is unbalanced, showing a spatial distribution pattern of weakness in the middle and strength in the periphery. The ring road network highlights the difference between the new and old urban areas. The high contribution indexes of community resilience in the main urban area of Changchun were concentrated on disaster relief materials input, community self-rescue ability, and disaster cognition ability. Finally, strategies to improve community resilience are proposed from the perspectives of stress, state, and response, emphasizing community residents’ participation, conducting disaster prevention and reduction training, and improving community response-ability.

Published: April 2023

This study investigates factors contributing to the injury severity of truck-involved work zones crashes in South Carolina (SC). The outcome of interest is injury or property damage only crashes, and the explanatory factors examined include the occupant, vehicle, collision, roadway, temporal, and environmental characteristics. Two mixed (random parameter) logit models are developed, one for non-interstates with speed limits less than 60 miles per hour (mph) and one for interstates with speed limits greater than or equal to 60 mph, using South Carolina statewide truck-involved work zone crash data from 2014 to 2020. Results of log-likelihood ratio tests indicate that separate speed models are warranted. The factors that were found to contribute to injury at the 90% confidence level in both models (interstate and non-interstate) are (1) dark lighting conditions, (2) female (at-fault) drivers, and (3) driving too fast for roadway conditions. Significant factors that apply only to non-interstates are SC or US primary roadways, activity area of the work zone, at-fault drivers under 35, sideswipe collision, presence of workers in the work zone, and collision with fixed objects. Significant factors that apply only to interstates are three or more vehicles, rear-end collision, location before the first work zone sign, and weekdays.

Published: April 2023

Health and sustainability problems have become a central theme in dialogue in both the scientific community and the public. Our individual choices have a profound, advantageous or disadvantageous impact on our health; the same can be said about our environmental footprint. In this area, we can also make decisions that affect the physical environment positively or negatively. Our narrative review aims to demonstrate that healthy plant-based choices in our diet are linked to choices beneficial for our environment and that these two seemingly distant aspects converge in the context of plant-based diets. We have collected, compared and discussed the results of life cycle analysis (LCA) articles on the current state of the effect of food choice on our environment. Furthermore, we would like to show the opportunities and constraints of implementing plant-based diets.

Published: April 2023

The key process in understanding carbon dynamics under different ecosystems is quantifying soil CO2 efflux. However, this process can change annually as it depends on environmental variables. The results of this paper present the effects of root network, soil temperature, and volumetric water content on soil CO2 efflux, which were investigated on Retisol of two types of land uses in Western Lithuania in 2017–2019: forest and grassland. It was determined that the average soil CO2 efflux in the grassland was 32% higher than in the forest land. The CO2 efflux, average across land uses, tended to increase in the following order: 2017 < 2018 < 2019. Dry weather conditions with high temperatures during the vegetation period governed the soil CO2 efflux increase by 14%. Soil temperature (up to 20 °C) and volumetric water content (up to 23–25%) had a positive effect on the soil CO2 efflux increase on Retisol. We established that the root’s activity plays one of the main roles in the CO2 production rate—in both land uses, the soil CO2 efflux was influenced by the root length density and the root volume.
Occurrence and Health Effects of Hexabromocyclododecane: An Updated Review
Authors: Marques Maria Lopes , Cairrao Elisa
Published: April 2023

Hexabromocyclododecane (HBCD) is a non-aromatic compound belonging to the bromine flame retardant family and is a known persistent organic pollutant (POP). This compound accumulates easily in the environment and has a high half-life in water. With a variety of uses, the HBCD is found in house dust, electronics, insulation, and construction. There are several isomers and the most studied are α-, β-, and γ-HBCD. Initially used as a substitute for other flame retardants, the polybrominated diphenyl ethers (PBDEs), the discovery of its role as a POP made HBCD use and manufacturing restricted in Europe and other countries. The adverse effects on the environment and human health have been piling, either as a result from its accumulation or considering its power as an endocrine disruptor (ED). Furthermore, it has also been proven that it has detrimental effects on the neuronal system, endocrine system, cardiovascular system, liver, and the reproductive system. HBCD has also been linked to cytokine production, DNA damage, increased cell apoptosis, increased oxidative stress, and reactive oxygen species (ROS) production. Therefore, this review aims to compile the most recent studies regarding the negative effects of this compound on the environment and human health, describing the possible mechanisms by which this compound acts and its possible toxic effects.

Enterotoxigenic Escherichia coli (ETEC) causing post-weaning diarrhea (PWD) in piglets have a detrimental impact on animal health and economy in pig production. ETEC strains can adhere to the host’s small intestinal epithelial cells using fimbriae such as F4 and F18. Phage therapy could represent an interesting alternative to antimicrobial resistance against ETEC infections. In this study, four bacteriophages, named vB_EcoS_ULIM2, vB_EcoM_ULIM3, vB_EcoM_ULIM8 and vB_EcoM_ULIM9, were isolated against an O8:F18 E. coli strain (A-I-210) and selected based on their host range. These phages were characterized in vitro, showing a lytic activity over a pH (4–10) and temperature (25–45 °C) range. According to genomic analysis, these bacteriophages belong to the Caudoviricetes class. No gene related to lysogeny was identified. The in vivo Galleria mellonella larvae model suggested the therapeutic potential of one selected phage, vB_EcoS_ULIM2, with a statistically significant increase in survival compared to non-treated larvae. To assess the effect of this phage on the piglet gut microbiota, vB_EcoS_ULIM2 was inoculated in a static model simulating the piglet intestinal microbial ecosystem for 72 h. This study shows that this phage replicates efficiently both in vitro and in vivo in a Galleria mellonella model and reveals the safety of the phage-based treatment on the piglet microbiota.

Published: April 2023

The hollow protein capsids from a number of different viruses are being considered for multiple biomedical or nanotechnological applications. In order to improve the applied potential of a given viral capsid as a nanocarrier or nanocontainer, specific conditions must be found for achieving its faithful and efficient assembly in vitro. The small size, adequate physical properties and specialized biological functions of the capsids of parvoviruses such as the minute virus of mice (MVM) make them excellent choices as nanocarriers and nanocontainers. In this study we analyzed the effects of protein concentration, macromolecular crowding, temperature, pH, ionic strength, or a combination of some of those variables on the fidelity and efficiency of self-assembly of the MVM capsid in vitro. The results revealed that the in vitro reassembly of the MVM capsid is an efficient and faithful process. Under some conditions, up to ~40% of the starting virus capsids were reassembled in vitro as free, non aggregated, correctly assembled particles. These results open up the possibility of encapsidating different compounds in VP2-only capsids of MVM during its reassembly in vitro, and encourage the use of virus-like particles of MVM as nanocontainers.
Comprehensive Effects of Atmosphere and Soil Drying on Stomatal Behavior of Different Plant Types
Authors: Xu Zhi , Tian Ye , Liu Zhiwu , Xia Xinran
Published: April 2023

The soil water supply and atmospheric humidity conditions are crucial in controlling plants’ stomatal behavior and water use efficiency. When there is water stress caused by an increase in saturated water vapor pressure (VPD) and a decrease in soil water content (SWC), plants tend to close stomata to reduce water loss. This affects the gross primary productivity (GPP) and evapotranspiration (ET), subsequently leading to changes in water use efficiency (WUE) and carbon use efficiency (CUE) in plants. However, land–atmosphere interactions mean that water vapor in the atmosphere and soil moisture content causing water stress for plants are closely related. This study aims to compare and estimate the effects of VPD and SWC on the carbon cycle and water cycle for different plant functional types. Based on the fluxnet2015 dataset from around the world, the WUE and CUE of five plant functional types (PFTs) were estimated under varying levels of VPD and SWC. The results showed that high VPD and low SWC limit the stomatal conductance (Gs) and gross primary productivity (GPP) of plants. However, certain types of vegetation (crops, broad-leaved forests) could partially offset the negative effects of high VPD with higher SWC. Notably, higher SWC could even alleviate limitations and partially promote the increase in GPP and net primary production (NPP) with increasing VPD. WUE and CUE were directly affected by Gs and productivity. In general, the increase in VPD in the five PFTs was the dominant factor in changing WUE and CUE. The impact of SWC limitations on CUE was minimal, with an overall impact of only −0.05μmol/μmol on the four PFTs. However, the CUE of savanna plants changed differently from the other four PFTs. The rise in VPD dominated the changes in CUE, and there was an upward trend as SWC declined, indicating that the increase in VPD and decrease in SWC promote the increase in the CUE of savanna plants to some extent.

The objective of this article is to carefully analyze and document the various uses, continuity and change as well as the eventual fate of the title Wäyzäro within the wider political, economic and social history of Ethiopia since the medieval times. Above all, this article explores how the function of this title in its wider sense has not been fully understood by neither Ethiopian nor foreign scholars. Based on both published and unpublished sources, this article questions and disproves the misconception that the title Wäyzäro in the past served solely for royal ladies, and shows instead that it was born by both female and male persons during different times and in different places. Additionally, this article draws upon the valuable living memories of Ethiopians from Wallo, Gojjam, Gondar and Tigray, and these accounts have been integrated into the source material.

A Machine Learning Approach to Predict HIV Viral Load Hotspots in Kenya Using Real-World Data
Authors: Kagendi Nancy , Mwau Matilu
Published: April 2023

Background

Machine learning models are not in routine use for predicting HIV status. Our objective is to describe the development of a machine learning model to predict HIV viral load (VL) hotspots as an early warning system in Kenya, based on routinely collected data by affiliate entities of the Ministry of Health. Based on World Health Organization’s recommendations, hotspots are health facilities with ≥20% people living with HIV whose VL is not suppressed. Prediction of VL hotspots provides an early warning system to health administrators to optimize treatment and resources distribution.

Methods

A random forest model was built to predict the hotspot status of a health facility in the upcoming month, starting from 2016. Prior to model building, the datasets were cleaned and checked for outliers and multicollinearity at the patient level. The patient-level data were aggregated up to the facility level before model building. We analyzed data from 4 million tests and 4,265 facilities. The dataset at the health facility level was divided into train (75%) and test (25%) datasets.

Results

The model discriminates hotspots from non-hotspots with an accuracy of 78%. The F1 score of the model is 69% and the Brier score is 0.139. In December 2019, our model correctly predicted 434 VL hotspots in addition to the observed 446 VL hotspots.

Conclusion

The hotspot mapping model can be essential to antiretroviral therapy programs. This model can provide support to decision-makers to identify VL hotspots ahead in time using cost-efficient routinely collected data.

ЗВ'ЯЗОК САМООЦІНКИ ФІЗИЧНОГО СТАНУ ТА МОТИВАЦІЇ СПОРТИВНОЇ ДІЯЛЬНОСТІ СПОРТСМЕНІВ-ЮНІОРІВ
Authors: Шандрук Сергій , Гах Роман
Published: April 2023

Актуальність дослідження. Проблема підвищення ефективності змагальної діяльності є актуальною, і для її вирішення потрібно розуміти особливості психологічного стану як кожного окремого спортсмена, так і загальні тенденції спортсменів взагалі. Більшість спортсменів, які виступають на олімпійських змаганнях та на інших змаганнях високого рівня, починали свою спортивну діяльність ще будучи підлітками, а деякі навіть в дитинстві. Саме тому важливо розуміти особливості формування спортивної успішності дитини-спортсмена та підлітка-спортсмена.

Мета дослідження – визначити кореляції мотивації спорту та самооцінки фізичного стану у спортсменів-підлітків.

Методи дослідження. Для отримання емпіричних даних було проведено опитування за допомогою методики Дембо-Рубінштейн «Діагностика самооцінки фізичних якостей та властивостей» в модифікації С. Лукової та К. Фоменко з десятьма шкалами компонентів СФС та опитувальника С. Лукової та К.Фоменко «Мотивація спортивної діяльності» (Фоменко&Лукова, 2021).

Результати. Проаналізовано мотивацію спорту у спортсменів-юніорів з різним співвідношенням самооцінки фізичного стану та рівня домагань.

Висновки. Адекватність рівня домагань та самооцінки фізичних якостей спортсменів-юніорів пов’язана із варіативністю мотивації спорту. При розриві самооцінки та рівня домагань головним мотивом є мотив соціального обов’язку, мотив фізичного самовдосконалення, конкурентний мотив, у той час, коли для більшості спортсменів з високою відповідністю самооцінки фізичного стану та рівня домагань головним мотивом є мотив фізичного вдосконалення, а на другому місці емоційний мотив.
Transformational leadership and acceptance of mistakes as a source of learning - Poland-USA cross-country study
Authors: Kucharska Wioleta , Kucharski Maciej Julian , Rehman Hafeez Ur
Published: April 2023

This study aims to explore the influence of transformational leadership on internal innovativeness mediated by mistakes acceptance, including country and industry as factors to be considered and gender and risk-taking attitude as moderators. General findings, primarily based on the US samples (healthcare, construction, and IT industry), confirmed that transformational leadership and internal innovativeness are mediated by mistakes acceptance and strengthened by employees' risk-taking attitude. It is reflected in Polish healthcare sample. On the other hand, IT and construction industry samples revealed that a low mistakes acceptance level among risk-taking managers under transformational leadership might be their hidden form of change resistance. Regarding gender issue, this study showed that male employees driven by transformational leaders accept mistakes as a source of learning better than women, but the exceptions are healthcare and IT industries in Poland. The developed empirical model is based on a sample composed of 2,160 Polish and American knowledge workers applying OLS regression, using SPSS PROCESS macro software.
Implementing Organizational Ethics in Academic Environment – The Case of Croatian University
Authors: Lovrincevic Marina
Published: April 2023

Despite its great importance as a crucial aspect of organizational culture, organizational ethics and the implementation of ethics initiatives at all levels of the organization are still largely misunderstood or even neglected, not only in the business world but also in academia. Given the role of universities in educating young people for the labour market and future jobs, the translation of defined and proclaimed ethical policies, norms, and formal documents into desirable ethical behaviours by individuals, departments, and faculties is a sine qua non requirement for any university. This is especially true in less developed countries and emerging economies where the challenge of creating an ethical environment in organizations, corporate or otherwise is even greater.

 

The main goal of the paper is to explore the interrelationship between formalized ethical policies and initiatives and demonstrated ethical behaviours at the organizational level, as well as to further investigate their role in shaping ethical behaviours of academic staff and, subsequently, ethical behaviours of students in an academic setting in a transitional economy. To achieve this goal, empirical research was conducted in 2021 using a specially designed questionnaire on a sample of 115 employees from one of the leading universities in Croatia. A moderated mediation model was designed and the analysis was conducted using PROCESS macro v4.0 for SPSS. The obtained results suggest that the effectiveness of standalone formalized ethical policies and initiatives is questionable in shaping ethical behaviours of academic staff, whereas these policies and initiatives in conjunction with actually demonstrated high ethical behaviours at the organizational level positively influence the ethical behaviours of academic staff. Moreover, the demonstrated ethical behaviours of academic staff plays an important mediating role in the positive impact of formalized ethical policies and initiatives on student ethical behaviours. In fact, demonstrated high ethical behaviour at the organizational level contribute positively to the indirect effects in this model. These and other findings of the research contribute to the relevant literature by providing additional confirmation of the importance of moving beyond formal ethics-related documents to actually demonstrated ethical behaviours in shaping ethical behaviours of individuals, in this case, university employees and students.
Universities of Applied Sciences’ Leadership Role in Regional Innovation Ecosystems
Authors: Yalcin Erkan
Published: April 2023

The 2030 Agenda for Sustainable Development contains 17 Goals. Goal 9 concerns building resilient infrastructure, promoting inclusive and sustainable industrialization and fostering innovation. Hence, the development of innovation ecosystems in the European community plays an important role. This development is carried out at all levels of governance with an emphasis on the regional governance. The innovation ecosystem approach considers innovation a process that emerges from interaction among different types of companies and other organizations. One of the common success factors and actors in the innovation ecosystem consists of educational organizations that provide access to knowledge and creating knowledge infrastructure. However, the role of universities of applied sciences is not clear in empowering regional innovation ecosystems. In this conceptual paper, the role of universities of applied sciences in regional innovation ecosystems, is discussed. The research has been carried out by conducting an integrative literature review to identify themes, debates and gaps about the role of educational organizations using the Regional Innovation System model (RIS-model) and the system elements for diagnosing ecosystems. The outline of the paper shows that there is a great potential for universities of applied sciences in taking a leadership role in the regional innovation ecosystem due to their neutrality, practical-oriented accumulated knowledge, and expertise in relation to different stakeholder groups. This paper provides an overview of the key findings regarding the potential leadership role of universities of applied sciences in the regional innovation ecosystem for the management board of universities of applied sciences and regional policy makers. Thus, contributes to the formulation of regional innovation policies by including universities of applied sciences more clearly as active partners.
Information Security Posture to Organize and Communicate the Information Security Governance Program
Authors: Tran Dinh Uy , Jøsang Audun
Published: April 2023

Information security practice has evolved greatly from being mostly a technical concern to also becoming a concern of executive management. As a result, there are many different frameworks, guidelines and certification programs for information security governance (ISG) and management. The purpose of these standards and certification programs is to help an organization develop a structured approach for governing and managing information security. However, these standards and guidelines are generic and not tailored for any specific organization. These frameworks usually specify “what” should be implemented but not “how”.  Additionally, these frameworks do not specify “how” to communicate the information security posture (ISP) to the executive management in a simplistic manner. This paper first defines and conceptualizes the term information security posture, and then proposes a framework on “how” to communicate and organize the ISP. Our contribution complements ISG programs adopted by organizations to give executive management a better understanding and oversight. We argue that describing the ISP of an organization will support well-informed decision-making while ensuring alignment with business objectives.
Building positive reputation and low risk for financial organizations, through Culture
Authors: Christakou Roila
Published: April 2023

In a continuously changing world environment, following financial crisis, pandemic crisis, wars, environmental disasters, along with the changes in the once “static” banking sector per-se, given the expansion of digital currencies, online financial services, expansion digital offerings, the rise of open-banking, one should expect a substantial change to an organisation’s reputation.

Risks are emerging from everywhere and have as a result the increased focus from investors and regulators on how culture is formed in financial institutions.

At the same time, culture (a quite diverse term that we will try in this paper to define and place in the banking sector frame), is considered to be a critical factor for banks to be able to respond effectively to all the changes and build long-lasting positive reputation and success. The ability to leverage the compliance program and embed ethics, top-down, contributes also significantly.

In this paper, we will try to define positive reputation for banks in this new era and set the grounds for the importance of understanding the need to manage or/and change Culture, along with aligning risks and people.
The Role of Machine Learning in Managing Uncertainty in Projects – A View on Early Warning Systems
Authors: Ekambaram Anandasivakumar , Vågbø Pål Christian , Van der Leyen Bjørn S.
Published: April 2023

Machine learning techniques deals with, among other things, pattern recognition in large amounts of data to identify trends and possible events in the future regarding a given topic of interest. Machine learning methods are useful for addressing challenges in and creating new benefits for organisations. This paper looks at how machine learning can contribute to manage projects effectively.

Many organisations apply the concept of project. A part of them are purely project-based organisations, and a part of them carry out projects in addition to their mass-production activities and permanent operations. Within the realm of project management, this paper sets its focus on studying the role of machine learning in handling unexpected events and uncertainty in projects. One of the ways to deal with unexpected events and uncertainty is to capture early warning signs that can predict unexpected events.

A major failure of projects can be seen as a combined effect of a series of small failures, negative results or problems that have occurred over a period of time. Project teams may not notice or just ignore early warning signs of these problems and choose to work further in the project. This could finally lead to a major failure, at which point no preventive actions could save the project from the major failure. Several researchers have researched on early warning signs and systems within the context of projects. Early warning signs can be seen as some kind of a pattern recognition from a pool of relevant data.

This paper aims to answer the following two interrelated research questions: (1) What role does machine learning have in early warnings in projects? (2) How can machine learning contribute to effective project management (for example, handling uncertainty in projects)? This is a conceptual paper, based on literature study.
