Exploring crisis management response to hybrid threats and warfare
Authors: Tikanmäki Ilkka , Ruoslahti Harri 
Published: November 2023

Abstract
Crisis management (CM) operations and organisations may face internal, external and hybrid threats (HTs) against their information and/or personnel. This research looks at how selected European Union (EU), North Atlantic Treaty Organization (NATO) and national perspectives address internal, external and global HTs and influence, even warfare, and maps some relevant strategies to prepare against them in a CM context. Strategies to fight against HTs include relevant political debate and decision-making, integration of EU- and national-level security into critical infrastructure and regular preparedness exercises. Responses to HTs call for relevant technical, situational awareness and problem-solving skills. This research shows how collaboration and situation understanding can assist in detecting and responding to possible cyber and HTs against CM operations. This study examines how collaboration and understanding the situation assist in detecting and responding to HTs to CM operations. There is evidence that information exchange and collaboration are important elements in the fight against hybrid influence and war. Combating misinformation through public education campaigns can support both the civilian and military elements of CM operations. Specific training can be designed to counter aggressive propaganda and disinformation efforts against personnel in CM operations. This maintains one’s initiative and trust in the aims of the mission.
The Impact of Consolidating On-Demand Food Delivery on Sustainability: A Simulation Study
Authors: Sunarso Radhitya V.P. , Wibowo Budhi S. 
Published: November 2023

Abstract
On-demand food delivery services have transformed the food industry, offering customers a convenient way to order their favorite food from restaurants and have it delivered to their doorstep. However, the increased number of delivery vehicles has led to higher costs, traffic congestion, and carbon emissions. To tackle these negative impacts, consolidating the delivery process by combining multiple orders from different restaurants to various customers has been suggested. This study evaluates the sustainability impact of direct versus consolidated orders in the on-demand food delivery sector. To achieve the objective, we used an agent-based simulation model based on real delivery data from Yogyakarta, Indonesia. Our simulation results indicate that due to constraints in time windows and routing complexity, only a small portion of all orders can be consolidated. But where consolidation is feasible, it can benefit businesses and the environment by reducing costs for customers, increasing drivers’ productivity, and reducing carbon emissions. The downside is that it may result in a longer customer waiting time. These findings provide valuable insights for businesses and policymakers seeking to promote sustainable practices in the on-demand food delivery sector.

Published: November 2023

Abstract
In mountainous regions, the atmospheric dispersion of air pollutants is limited by complex terrain morphology. Trentino (a province located in the Italian Alps) is characterized by a high population density, highly developed agriculture and farming, and the presence of civil and industrial activities, whose emissions tend to be trapped inside the valleys. These conditions translate into exposure levels that are potentially higher than other geographical contexts (e.g., flat or coastal regions). The academic research carried out in Trentino since 2005 has produced a series of publications on topics related to the risk for health derived from waste management and other activities. These publications has focused on: 1) the evaluation of the emissions of organic pollutants from the waste sector; 2) the monitoring of persistent organic pollutants (POPs) in various environmental matrices; 3) a methodology to carry out a comprehensive health risk assessment considering all the relevant exposure routes in an area; 4) the role of the local diet in the exposure of a population to POPs; 5) methodologies to define new regulatory limit values for dioxin and hexavalent chromium; and 6) the role of dispersion modeling in assessing the exposure to air pollutants. The present paper will review these publications and provide a reference document to evaluate new project proposals that require a health risk assessment and facilitate the work of proponents, clarifying the requirements of a health risk assessment. The paper will refer to waste gasification, but the considerations expressed in this paper may apply to other activities.

Authors: Saadi Marwa Q. , Dhannoon Ban N. 
Published: November 2023

Cyberbullying is one of the biggest electronic problems that takes multiple forms of harassment using various social media. Currently, this phenomenon has become very common and is increasing, especially for young people and adolescents. Negative comments have a significant and dangerous impact on society in general and on adolescents in particular. Therefore, one of the most successful prevention methods is to detect and block harmful messages and comments. In this research, negative Arabic comments that refer to cyberbullying will be detected using a support vector machine algorithm. The term frequency-inverse document frequency vectorizer and the count vectorizer methods were used for feature extraction, and the results were improved using the cuckoo search algorithm. The resulting accuracy before and after optimizing the support vector machine’s hyperparameters is 85.8% and 87.1%, respectively.

Published: November 2023

Many species are resistant to heavy metals in their surrounding polluted environment and Staphylococcus sp. is an example. This study aimed to isolate and characterize bacteria resistant to heavy metals in the Shatt Al-Arab River in southern Basra, Iraq. Based on the morphology and using Vitek II system, and due to their high resistance to heavy metals (mercury and chromium), two species of Staphylococcus (Staphylococcus lentus and Staphylococcus lugdunensis) were chosen and isolated. The minimum inhibitory concentration (MIC) of the isolates against Hg and Cr was determined after 72 h. of incubation in solid media. All isolates were resistant to Hg (2000 mgL-1) and Cr (4000mgL-1). Living biomass of S. lentus and S. lugdunensis was used to remove the heavy metal ions in various concentrations (5, 10 and 25 mgL-1) of the solutions of aqueous metals. After 72 hours incubation, the removal percentage of S. lugdunensis was 98.91 and 78.78% for Hg and Cr respectively. That for S. lentus it was 77.83% for Cr after 72 hours, and 98.84% for Hg after 24 h. of incubation. The scanning electron microscope approved that the removal of these metals causes morphological changes in bacteria.

Published: November 2023

Advanced takeoff trajectories are proposed for supersonic transport noise reduction by capitalizing on excess engine thrust and improved aerodynamic efficiency at higher takeoff speeds. These novel trajectories use i) automatic continuous control of thrust, ii) increased takeoff speed, and iii) reduced cut-back altitude, compared to conventional pilot-initiated discrete thrust cut-back procedures currently used for subsonic transport. In this paper, we develop an optimal control framework to assess the attributes of effective takeoff trajectories for supersonic transport that yield minimum noise levels. We quantify the noise reduction potential of advanced takeoff trajectories for the eight-passenger, 55-metric-ton, Mach-1.4 NASA Supersonic Technology Concept Airplane. For the aircraft examined, these advanced takeoff trajectories enable a cumulative certification noise reduction of 10.6 EPNdB, which is insufficient to meet current subsonic transport noise limits.

Authors: Riza Fahrul , Luhur Novia Agatha 
Published: November 2023

This study examines the impact of technology orientation on entrepreneurial orientation and its consequent effect on the innovation performance of Indonesian startups. In this study, 156 local startups were examined using the structural equation model (SEM). The results demonstrate a significant and positive relationship between innovation performance and both entrepreneurial and technology orientation. Notably, the technology orientation has a positive effect on the entrepreneurial orientation, which partially mediates the indirect relationship between the technology orientation and innovation performance. This study's integrated framework concept to enhance the innovation performance of startups in emerging economies is unprecedented. The findings also urge businesses to adopt proactive, inventive, and risk-taking practices to keep up with the rapid pace of technological advancements. Certain limitations of this study must be acknowledged, including the subjective evaluation of constructs by senior management and the deliberate selection of the sample. To advance this topic further, it is suggested that future research include objective data gathered through assessments by various stakeholders and investigate case studies of designated businesses.JEL: L25, l26, O32.

ABSTRACT

Objective.

To analyze the temporal trend of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019.

Methods.

This was an ecological time series study of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019. Data were extracted from the Notifiable Disease Information System and the Mortality Information System, and population estimates were from the Brazilian Institute of Geography and Statistics. Trends were analyzed by Joinpoint regression, which recognizes inflection points for temporal analysis.

Results.

The average incidence rate of tuberculosis in Brazil in the period was 35.8 cases per 100 000 population. From 2011 to 2015, this coefficient had an annual percentage change of –1.9% (95% CI [–3.4, –0.5]) followed by an increase of 2.4% (95% CI [0.9, 3.9]) until 2019. The average mortality rate between 2011 and 2019 was 2.2 deaths per 100 000 population, with an average annual percentage change of –0.4% (95% CI [–1.0, 0.2]). Amazonas was the only state with an increase in the annual average percentage variation for the incidence rate (3.2%; 95% CI [1.3, 5.1]) and mortality rate (2.7%; 95% CI [1.0, 4.4]) over the years, while Rio de Janeiro state had an increasing inflection for incidence from 2014 to 2019 (2.4%; 95% CI [1.4, 3.5]) and annual average of decreasing percentage variation (–3.5%; 95% CI [–5.0, –1.9]).

Conclusions.

During the period analyzed, a decreasing trend in incidence was observed between 2011 and 2015, and an increasing trend for the period from 2015 to 2019. On the other hand, no change in the trend for mortality was found in Brazil.

Published: November 2023

The article reports on comparative analysis of high technology exports and selected innovation indicators for Serbia and three CEE countries – Hungary, Romania and Bulgaria for the 2011-2015 period, with an aim to provide an insight on the innovation potential of Serbia. The analysis is based on data publicly available at Eurostat and the Global Innovation Index rankings. The selection of countries for country comparison is based on many similarities such as historical circumstances and geographical position. HTP exports are exports of high technology products as a share of total exports. As for innovation indicators, the article considers the Global Innovation Index (GII) which provides metrics about innovation performance of countries and economies, as well as values of selected inputs contained in the innovation pillar of the GII such as costs, R&D investment (total by sector) and number of researchers (in total and by sector). The analysis shows that there are considerable differences between Serbia and the three CEE countries. The analysis results are divided into three groups according to impact on the HTP export. The first group refers to innovation indicators with significant impact on HTP exports such as GDP, number of researchers, the GII rank and R&D costs in the business enterprise sector. The second group are innovation indicators with significant impact on HTP export such as total R&D costs, and finally the third group are innovation indicators with little impact on HTP export.
Information and Communication Technology’s Skills among the Working Population of Serbia
Authors: Banović Jelena , Pavlović Dejana 
Published: November 2023

Major social shifts in the economy conditioned by Information and Communication Technology (ICT) have led to equal shifts in the labor market. In this paper, the use of ICT skills in Serbia is presented through an analysis of the microdata from the survey “The Usage of Information and Communication Technology on individuals/households in the Republic of Serbia for 2020”. Results showed that Internet users have increased in the last five years. According to results, in 2020, 78.4% of people between 16 and 74 used computers in the last three months. The number of unemployed who used a computer in 2020 was 83.6%, and the number of employed who used a computer was 92.7%. Students used computers 99.8% in 2020. On the other hand, 96.3% of employed used the Internet in 2020, while 89.2% of unemployed used Internet at the same period. The use of e-government web services is almost present to the same extent among students, the employed and unemployed. Unlike online shopping, students are most likely to use e-government services, even though the employed and unemployed both use online shopping equally. However, comparing statistical data, Serbia is not at the European level in ICT usage , which can significantly jeopardise individuals' position in the labor market. There are substantial distinctions between youth and older individuals, especially regarding advanced skills. This affects the creation of digital exclusion, which increases the lack of resources that can be employed in better-paid jobs. The main solution for solving the digital divide is education to ensure equal competitiveness for all individuals on the labor market.

Published: November 2023

The strategic contributions of digital technology in the operations and performance of entrepreneurial ventures are a profound phenomenon, involving continual adaptation to a constantly evolving business environment. This paper examines the influence of digital technology on female-owned enterprises based on customers satisfaction in Federal Capital Territory (FCT), Abuja, Nigeria. Survey research was employed to derive primary data through the use of structured closed-ended questionnaires from 113 selected female-owned enterprises registered with NECA's Network of Entrepreneurial Women (NNEW). Adopting digital orientation, digital capability and digital transformation as dimensions of the digital technology which is the independent variable, multiple regression was used to measure its impact on customer satisfaction as the dependent variable. Findings revealed that the awareness of digitalisation does not suffice to influence business performance, but adopting and adapting to new technology is crucial in creating value addition to meet and exceed customers’ expectations. Conclusively, this research establishes the requisite for female-owned enterprises to embrace and exploit the vast potential and significant role that digital technology plays in the enhancement of business performance, for improved strategic competitive advantage and economic development.
