Determinants of board membership in Publicly-Owned Enterprises
Authors: Berisha Hajdin , Ramosaj Berim , Krasniqi Besnik
Published: December 2023

Board structure is considered one of the most important determinants of board effectiveness. This study examines the personal motives of individuals seeking board membership in Publicly-Owned Enterprises (POEs). Using the sequential mixed methods approach, thirteen in-depth interviews were conducted with current and former board members, and one hundred and thirty-seven (137) questionnaires were administered to key representatives and beneficiaries of POEs. The results indicate several factors that motivate board membership. We find that intrinsic motives, which we refer to as ‘personal benefits,’ and extrinsic motives, which we refer to as ‘social recognition,’ are the most important factors for joining POE board membership. The findings could be helpful in redesigning strategies and policies for appointing professional board members whose primary incentives for board membership are related to POE development rather than personal benefits and self-recognition.
Understanding individual entrepreneurial orientation
Authors: Knezović Emil , Aydin Šejma , Smajić Hamza , Bičo Azra
Published: December 2023

Current research on entrepreneurial orientation is mostly from a firm-level perspective, focuses on developed countries, and recent studies treat entrepreneurial orientation as a uni-dimensional construct. Studies on entrepreneurial orientation from a generational perspective mostly use a comparison between two groups (young and old) and neglect the well-accepted classification of generational cohorts. This study therefore examines the individual dimensions of entrepreneurial orientation (risk-taking, innovativeness and proactivity) among the Baby Boomers, Generations X, Y, and Z in Bosnia and Herzegovina. Data were collected through a cross-sectional survey that yielded a sample of 1,082 adults from Bosnia and Herzegovina. One-way analysis of variance with Brown-Forsythe, Welch’s F, and least significant post-hoc tests were used to test the hypotheses. The results show some evidence that individual entrepreneurial orientation varies significantly between generations, at different levels of significance. Risk-taking generally decreases with older generations, as does innovativeness, except when comparing Generations X and Y, while proactiveness increases with older generations. The study provides valuable information for future entrepreneurs, business incubators and potential investors.
Alignment of workplace wellbeing initiatives with WHO’s “Guidelines for mental health at work”
Authors: Molek-Winiarska Dorota , Leduc Caleb , Chomątowska Barbara
Published: December 2023

The workplace offers an ideal setting for promoting health and well-being. The World Health Organisation (WHO) has recently published guidelines and recommendations for promoting mental health and well-being in the workplace based on the latest empirical evidence. However, little is known regarding its alignment with current practices within organisations. The purpose of this paper is to explore the extent to which mental health and well-being initiatives implemented in organisations outside the context of a formal research evaluation align with the WHO Guidelines for Mental Health at Work. Other objectives of the study are to identify trends within current initiatives and to explore whether the number or types of initiatives align with the WHO Guidelines, depending on the size of the organisation. The study used a secondary data analysis approach for a series of case studies collected over a three-year period (2020 to 2022). A total of 333 well-being initiatives from 52 Polish and international organisations were described. The results show a wide variety of initiatives undertaken by organisations, most of which are universal individual intervention types and are implemented by large organisations. A discussion of the strengths, gaps, and opportunities for future implementation and subsequent alignment with the latest evidence-based recommendations is provided.
Green budgeting implementation in financing of sustainable society - experience of Slovenia
Authors: Stanimirović Tatjana , Milan Lah Lenart , Kotnik Žiga , Klun Maja
Published: December 2023

Sustainable societies of the future should be designed on the basis of a green public budgeting, as green public 79 spending and investment are the key drivers of sustainable development. Studies on green budgeting have so far tended to focus on green taxes and favourable regulatory regimes for specific sectors, although 14 out of 38 OECD countries have introduced these in some form. Based on secondary research of Slovenian budget documentation for the period from 2018 to 2022, our research findings show that green and sustainable content is weak, both in terms of content and scope. Only 11 out of 24 policies and only 23 out of over 3000 projects have included some ideas of the green and sustainable concept. Due to the evolving methodology and framework of green budgeting, the research challenge could be identified in a repeated and deeper analysis, including the targets and indicators in the coming years.
Variations of Self-Employed in Eurozone Countries: The Role of Corruption and Wage Rate Growth
Authors: Papanikos Gregory T.
Published: December 2023

This study emphasizes two variables as significant determinants of the number of individuals who choose self-employment. First, it is assumed that the opportunity cost of self-employment has a negative effect. This cost is measured as the income that would be earned in wage employment. Second, self-employment provides more opportunities for tax evasion and tax avoidance. The higher the corruption rate, the higher the self-employment rate. These two variables—wages and corruption scores—are used as potential determinants of the ratio of self-employed persons to the total labor force. Data from the twenty Eurozone countries are employed to test these hypotheses. Both hypotheses cannot be rejected based on the empirical evidence. Keywords: Eurozone countries, wage growth, self-employment corruption, labor force, unemployment
Does Education Help Local Economies Reach Economic Potential? Evidence from South Africa
Authors: Tavonga Mazorodze Brian , Maduku Harris
Published: December 2023

It is widely understood in development circles that poverty alleviation is elusive unless local economies operate productively with limited resources and existing technology. With a high rate of poverty on the back of weak output growth at municipality level in South Africa since 1994, this background makes it necessary to establish factors that could increase the pace of economic development and help local economies produce at full capacity. Using a stochastic frontier analysis of South Africa’s 234 municipalities observed between 1995 and 2018, this paper finds postgraduate education (Masters and Doctorates) relevant in explaining the ability of these local economies to reach their full potential and the effect increases with the size of the manufacturing sector, life expectancy and trade. The stock of high school, diplomas, bachelors, and honours does not significantly contribute towards productive efficiency of these 234 municipalities reinforcing concerns of a possible structural mismatch between lower-level qualifications and the labour market demands. Consequently, moving these municipalities closer to their full potential may be achievable through ensuring that the undergraduate cohorts reach Masters, and PhD level complemented by a manufacturing-oriented structural change. Keywords: education, technical inefficiency, structural transformation, stochastic frontier model, local municipalities, South Africa
Plutarch’s Hesiod: Tradition and Identity Formation in a Greco-Roman Context
Authors: Malisse Peter
Published: December 2023

In Plutarch’s times Hesiod was still seen as the second founding father of Panhellenic culture and identity. For various reasons Plutarch held Hesiod in high esteem and played an important role in keeping the poet under the spotlight of paideia. In present article three Plutarchan sources are re-examined Hesiod’s claim to have won a poetry contest: Schol. Hesiod WD 650-662 and references to the story in Table Talk and The Dinner of the Seven Wise Men. Starting point is a close reading of the Proclan scholion in the light of Plutarch’s sympotic work. While the former introduces a Plutarch averse to mythopoeia, the latter shows just how important story-telling is to him in promoting and maintaining Panhellenic tradition and identity under a Roman rule.
In the search for all zeros of smooth functions
Authors: Plaskota Leszek
Published: December 2023

We consider the multi-valued problem of nding all solutions of the equation f(x) = 0 in the space of functions f : [0, 1] → R such that the derivative f(r) with r ∈ {0, 1, 2, . . .} exists and is Hölder continuous with exponent ϱ ∈ (0, 1]. Available algorithms use information about values of f and/or its derivatives at adaptively selected n points, and the error between the true solution Z(f) and approximate solution Zn(f) is measured by the Hausdor distance dH(Z(f),Zn(f)). We show that, despite the fact that the worst case error of any algorithm is innite, it is possible to construct nonadaptive approximations Z∗n such that the error dH (Z(f),Z∗n(f)) converges to zero as n → +∞. However, the convergence can be arbitrarily slow. Specically, for arbitrary sequence of approximations {Zn}n≥1 that use n adaptively chosen function values and/or its derivatives, and for arbitrary positive sequence {τn}n≥1 converging to zero there are functions f in our space such that supn≥1 τ−1n dH(Z(f),Zn(f))= +∞. We conjecture that the same lower bound holds if we allow information about values of n arbitrary and adaptively selected linear functionals at f.

Authors: Pereiro Julieta , Hernández Candela
Published: December 2023

Este artículo presenta resultados de una investigación realizada por la Junta de Seguridad en el Transporte para conocer los determinantes de uso del cinturón de seguridad de las personas usuarias de los servicios regulares de ómnibus de larga distancia en Argentina. La perspectiva teórica recupera nociones del modelo sistémico para el análisis de accidentes que orienta a observar las interacciones entre las condiciones del sistema y el comportamiento de los actores, valiéndose también de herramientas provenientes de la sociología y la teoría política. El método utilizado consistió en una encuesta a pasajeras/os en distintas terminales de ómnibus de Argentina. Los principales hallazgos sostienen que el cinturón es valorado como un elemento de seguridad, pero que solo una porción minoritaria informa utilizarlo siempre al viajar, influyendo la edad y el nivel educativo. También que las personas usuarias perciben débiles incentivos por parte del sistema para utilizar este dispositivo de seguridad.
Instrumentos de gestión de suelo. Revisión de la experiencia comparada
Authors: Guevara Tomás
Published: December 2023

La problemática del acceso al suelo urbano es estructural en las ciudades latinoamericanas. La restricción en el acceso al suelo urbano coadyuvó a la proliferación de barrios populares. La posterior regularización dominial e integración sociourbana ex post de estos barrios es mucho más costosa y compleja en términos de implementación de políticas públicas, y genera un círculo vicioso de la informalidad. Esta realidad ha motivado que se extienda la discusión sobre la necesidad de aplicar regulaciones en el mercado de suelo urbano que permitan capturar plusvalías para su redistribución, movilizar suelo ocioso, recuperar suelo fiscal en desuso o subutilizado, entre otras medidas. El objetivo de este trabajo es elaborar una revisión en materia de implementación de instrumentos de gestión de suelo, haciendo hincapié en los marcos conceptuales de los que se nutren y relevando las aplicaciones existentes.

Research of electric vehicle battery packs and charging stations based on an active three-phase rectifier
Authors: Bahach Ruslan
Published: December 2023

Problem. The proliferation of electric vehicles has underscored the need for the development of energy-efficient charging stations and systems. These systems must deliver high efficiency, maintain a power factor close to unity, adhere to electromagnetic compatibility standards, emit low levels of higher harmonics, and enable fast charging capabilities. Current electric vehicle charging devices encounter issues such as significant power losses, high harmonic emissions to the power grid, and challenges in implementing fast charging modes. Consequently, enhancing the energy efficiency of charging stations – by reducing power losses, minimizing harmonic emissions, ensuring a high power factor, and supporting modes for regulated current and voltage sources for fast charging – is a pressing concern. Goal. The aim of this work is to perform a comparative analysis of different types of batteries for electric vehicles, exemplified by TESLA cars, presenting comparative characteristics of lithium-ion, lithium-iron-phosphate, and lithium-titanate batteries. Methodology. The study showcases an evaluation of battery units for electric vehicles and outlines a comparative assessment of lithium-ion, lithium-iron-phosphate, and lithium-titanate batteries. The research focuses on enhancing the energy efficiency of electric vehicle charging station systems through the use of active rectifiers, with modes for active power factor correction and optimal configuration. Results. An examination of the quality of converters for electric vehicle charging stations was conducted, proposing schemes for a three-phase active voltage source rectifier and an active current source rectifier. Power circuitry and space-vector switching states for power transistors are introduced. Analysis concludes that an active current rectifier may be a more promising topology. Originality. A model of a charging station based on an active current source rectifier was developed using Matlab/Simulink. Transient processes of the converter's operation and the charging of a 60 kWh battery pack were examined. It was found that the active rectifier facilitates regulation of the battery charging current, achieves a power factor close to unity, and maintains a low level of higher harmonic emissions with a harmonic distortion factor of 2.52%. Practical value. The advancement of electric vehicles necessitates the ongoing development and enhancement of the energy indicators for electric vehicle batteries and the converters of charging stations, especially those that enable fast charging. Active progress is being made in each of these areas.

Estimation of phenyl alanine ammonialyase (PAL) and some phytoalexins in Vicia faba plants infected with spot disease caused by Alternaria alternata
Authors: Al-Ameri Hadeel A.
Published: December 2023

Biological agents are an important approach to controlling many fungal phytopathogens; plants produce phytoalexins such as phenol, alkaloids and tannins as a response to the biotic stresses. The results showed that the addition of the biological control of Trichoderma harzianum to Alternaria alternata caused an increase in the activity of the enzyme phenylalanine ammonialyase (PAL) after 20 days from the start of the greenhouse experiment, which was 6.21 mmol/min in the Spinal variety, compared with the enzyme activity in the treatment with  A. alternata alone, which was 5.51 mmol/min.  The variety Netherland mulch recorded a lower phenolic content in all treatments, and the treatment with biological control T. harzianum in addition to A. alternata had the highest content as it reached 4.50 mg/g on day 20, Netherland mulch variety showed the most amount of alkaloids and tannins than others during different periods. The plants treated with the biological control of T. harzianum contained the most alkaloids on day 20, which was 5.15% It decreased to 3.65% on day 30. The most tannins in Netherland mulch variety were in the plants treated with biological control  T. harzianum alone, which was 3.93% on day 20, compared to the plants treated with A. alternata alone, which was  0.71%. The addition of biological control of T. harzianum to A. alternata increased the plant amount of tannins, which was  2.01%. The study would help to understand the role of T. harzianum as a biological control to the response of the varieties to the formation of plant defenses, including phytoalexins.

The present study aimed to evaluate the impact of A. vera on their haematological, biochemical, and immunological parameters. Twenty male Wistar albino rats were taken and split into two groups. Group I (Treatment Group)received a prepared aqueous A. vera extract at a concentration of 50 mg/kg of body weight for a full 30 days. Group II (Control Group) was given 0.9% normal saline as a placebo.The study found that the rats that received the A. vera extract had significantly (p<0.05) higher packed cell volume (14.8±1.08) compared to the control group (11.26±0.45). However, there were no significant changes in the levels of hemoglobin (Hb), red blood cell count (RBC),mean corpuscular hemoglobin (MCH) concentration, white blood cells (WBC) count, platelets count, and mean corpuscular volume (MCV). The serum alanine transaminase (ALT) concentration (U/L) was significantly (p<0.05)  lower in the treated group (39.54±7.74) than in the control group (77.68±6.96), while there were no significant changes in the levels of urea and creatinine compared to the control group. The plasma levels of proinflammatory markers(TNFa, IL-6, and IFNγ) showed no significant differences between both groups. Overall, A. vera showed promise as a natural remedy for improving certain aspects of health, but more research is needed to understand its effects fully.

Pantoea is an opportunistic bacterium primarily involved in nosocomial infections, impacting newborns and immunocompromised patients. The study aimed to investigate the virulence factor of Pantoea in urinary tract infections in hospitals in Al-Nasiriyah City, Iraq. The outcome appeared that 22 isolates out of 100 urine samples had been confirmed as Pantoea species by VITEK- 2. RcsA and hrpA genes were detected using conventional Polymerase Chain Reactions (PCR) and specific primers. The distribution of rcsA and hrpA was 40.9% and 59.1% respectively. The Pantoea species were distributed according to age, gender, and ABO blood groups. The percentage was 72.3% for ages 40–70, and females recorded 54.5% more than males. Individuals with the A blood group had a higher percentage (50%) than other blood groups; there were two types of variations (Transversion and Transition) of the16S rRNA gene. It was determined through the sequence alignment, and the symmetry was 90% with the Italian isolate of Pantoea species LL92 (ID: KF202812.1). These variations in the Pantoea local Iraqi isolate were registered in NCBI (ID: OM971851).This bacterial genus recently descended from the species of  Enterobacter sp.. The isolation of  Pantoea sp.was from UTIs, while previously, in most studies, they were isolated from the surrounding environment.

Authors: Sheoran Garima , Shukla Vineeta
Published: December 2023

Microplastics, measuring less than 5 mm, are pervasive environmental pollutants raising concerns about their toxic effects on terrestrial ecosystems, especially earthworms.A comprehensive toxicological evaluation of polyethylene microplastics on earthworms will be beneficial for determining the detrimental impacts of these ubiquitous pollutants on soil ecosystem. Therefore, in the present study, the best representative soil organism, earthworms (Eisenia fetida), were opted for examining the toxicological effect of polyethylene microplastic. E. fetida were subjected to different concentrations of polyethylene microplastic (200, 400, 600, 800, and 1000 mg/kg) in soil and randomly picked out on days 7 to 56. Earthworms exposed to higher concentration of polyethylene (1000 mg/kg of artificial soil) showed a significant reduction in body weight and cocoon formation after 35th days of incubation. A consistent decrease in the concentration of carbohydrates, lipids, and protein was observed when the worms were exposed to the higher concentration of polyethylene. Further, antioxidant enzymes like superoxide dismutase, glutathione S-transferase, peroxidase, catalase, and malondialdehyde were determined for antioxidant stress.Exposure of 200 mg/kg to 1000 mg/kg of artificial soil caused a prominent amplification in the build-up of malonedialdehyde (a biological marker of oxidative stress) by 1.29-fold. It also considerably augmented the activity of the antioxidant enzymes viz., glutathione S-transferase (1.54-fold), superoxide dismutase (1.51-fold), peroxidase (1.25-fold), and catalase (1.87-fold). The present study's findings provide a new understanding of the toxic effect of microplastic on earthworm E. fetida, presenting a foundation for its risk evaluation on soil ecosystems and non-target biological toxicity.

Published: December 2023

Coastlines have been subject to ongoing vulnerability from natural disasters, resulting in erosion and accretion occurring at varying intervals. The impacts of human activities and alterations in natural processes, including those induced by climate change, exacerbate the existing challenges faced along coastal regions. The present study aimed to analyze the changing shoreline along the Bapatla coastal tract in the upper coromandel coast of Andhra Pradesh due to erosion and accretion using the DSAS toolbar in ArcGIS software. Multiple statistical methods are available in DSAS; the present study confined  attention to the end point rate (EPR), linear regression rate (LRR), and net shoreline movement (NSM) for this investigation. The Nizampatnam Mandal had the greatest erosion rate (-16.8 m/yr) and accretion rate (10.5 m/yr), according to EPR, as well as the highest erosion rate (-16.7 m/yr) and accretion rate (10.4 m/yr) according to LRR. As per NSM, between 1990 and 2020, the highest erosion and accretion was seen again in Nizampatnam. The shoreline at Nizampatnam either retreated by as much as -285.2 meters or advanced by 211.1 meters. The research indicated that the Bapatla district's shoreline is susceptible to erosion and accretion.   The present investigation revealed that the coastal region of Bapatla district exhibits susceptibility to both erosion and accretion phenomena. The findings of the present study hold significant implications for professionals in the fields of coastal science, engineering, and administration. The findings are of utmost importance in the development of sustainable approaches for coastal management.

The absence of an integrated geospatial database hinders effective decision-making among various stakeholders in national projects and programs. The study aimed to create an integrated geospatial database for the Manesar tehsil, District Gurugram, Haryana. Another objective was to create a land use map to analyze the temporal change in land use patterns and its socioeconomic impact along the surrounding areas. The first stage of the study involved creating an integrated database after interviewing different stakeholders. In the second stage, the satellite imagery was georeferenced using Ground Control Points, and the land use patterns were digitized using Landsat imagery for 1987, 2011, 2014, and 2022. The study suggested that the construction area has grown up to 6% while cultivation has dropped significantly from 76% in 1987 to 50% in 2022. Likewise, the industrial area has grown up to 2% and natural vegetation dropped in coverage from 11% to 4%. The area witnessed a population growth rate of 3.2% per year and a decadal growth rate of 39.7%. Less than 50% of the land in the tehsil is used for agricultural purposes. It estimates that 4% of the tehsil's entire surface was covered by natural vegetation in 2019, down from 11% in 1987. The study recommends the creation of an integrated geospatial database that will help reduce duplication and speed up decision-making in government. This will pave the way for improving e-governance in local bodies.  The framework created for developing the database system is universally applicable and can be used appropriately by other states, regions, and the entire country.

Published: December 2023

Estimating peak discharge in the catchment poses a challenge for hydrologists due to the potential overflow risks. The present study examined various methods, including Synthetic unit hydrograph, Melchior, and Rational, to determine the peak discharge value in the Lesti River Catchment Area. Accurate hydrological input data is essential for effectively estimating peak discharge and mitigating potential damage or failure. Optimized physical parameters using geographic information systems are critical in generating peak discharge values, emphasizing their importance in the estimation process. The mean absolute percentage error (MAPE) and mean average error (MAE) were used to determine the accurate method for estimating peak discharge. Analysis results showed varied peak discharge values across different methods, and it found that the MAPE values ranged from 15.15% to 7.48% and the MAE values ranged from 1.47% to 0.63%, respectively. The Nakayasu synthetic unit hydrograph obtained the minimum error measure value compared to other methods by 7.48% in MAPE and 0.63% in MAE. Therefore, the MAPE and MAE performance considered that the Nakayasu was closely approximating the observed peak discharge and a relatively accurate method for estimating peak discharge in the Lesti River catchment area.

Authors: Bylappa Yatheesharadhya , Nag Anish
Published: December 2023

Guava (Psidium guajava L.) is a highly nutritious and economically important fruit. Although fruit peel is generally regarded as a waste, researchers believe that the peel of the guava is rich in bioactive constituents, even higher than the fruit's flesh. The present study aimed to estimate phenolic content (total phenolic and total flavonoid) and assess antioxidant properties of guava fruit peel (pink variety, cv Arka kiran) by 2,2-di (4-tert-octylphenyl)-1-picryl-hydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and Ferric Reducing Antioxidant Potential (FRAP) assays at five different ripening stages (stage 1 to 5). The TPC and TFC assays were performed by Folin-Ciocalteu and aluminium chloride (AlCl3) methods, respectively. The molecular docking experiment between the major phenolic of guava peel, Catechin and the spike protein of SARS-CoV-2 was performed by the Dockthor online server. Results showed that the peel had high phenolic (highest TPC and TFC, 7307.3 mg gallic acid equivalent/g dry weight [DW] and 433.9 mg quercetin equivalent/g DW, respectively) and antioxidant values (highest DPPH, ABTS and FRAP values 4784.8, 206.6 and 2451 mg ascorbic acid equivalent/g DW, respectively) throughout all stages, although there was a gradual decline in the activity at the later stages. Furthermore, it was found that catechin had a strong binding affinity (-7.591 kcal mol-1) with the spike protein, in silico when compared with the control drug ceftazidime (-7.250 kcal mol-1). The overall outcome of our experiemnts revealed that guava peel could be explored for future pharmacological applications through in vivo studies, and the ‘green mixed with the yellow’ stage of ripening is optimum for such studies.

The increase in population and rapid industrial development have resulted in surface water pollution that stresses groundwater resources to ensure sustainable consumption and human well-being. The present study was aimed to assess the physico-chemical characteristics and heavy metal concentration of groundwater in Aizawl city. The study also seeks to determine the indicator parameters of water quality through analysis of variance (ANOVA) and correlation coefficient in relation to physico-chemical properties. The results revealed that all physico-chemical parameters were within the regulatory standards, except turbidity (80.9 NTU) and phosphate (0.6365 mg/L). Trace amounts of Zinc (Zn) and Copper (Cu) were also present; however, Iron (Fe) and Manganese (Mn) slightly exceeded (Fe: 1.162 mg/L; Mn: 0.6892 mg/L) the permissible limit. Statistically, two-way ANOVA revealed that temperature, chloride, total alkalinity (TA), total hardness (TH), calcium, and dissolved oxygen (DO) were significant (p<0.001) both between sites and seasons. Further, TH showed positive and significant correlation with total dissolved solid (TDS) (R2=0.792), chloride (R2=0.52), TA (R2=0.62), calcium (R2=0.88), and Zn (R2=0.61). Conversely, DO demonstrated negative and significant correlation with turbidity (R2=-0.73), chloride (R2=-0.52), phosphates (R2=-0.70), ammonia (R2=-0.81), and Mn (R2=-0.58). These results indicate that the analysis of TH and DO can serve function as proxies for indirectly indicating the presence and concentrations of the other correlated water quality parameters. Thus, TH and DO act as indicator parameters for water quality in holistic groundwater monitoring in Aizawl. The identification of water quality indicator parameters can play a key role in future research for cost-effective, rapid, and seasonal groundwater monitoring to ensure the sustainable management of this resource.
