Actors in the Knowledge Economy: A Typology
Authors: Tomé Eduardo
Published: March 2024

The purpose of this paper is to construct a typology of actors in the knowledge economy, based on the specificity of their activities. So far, almost all the researchers focused their interests on organizations and their management in the knowledge economy ignoring the actors who perform and make the progress of the new economy based primarily on intangible resources. The main criterion for this typology is the positioning of these actors with respect to knowledge, as an intangible resource of any economic activity. The whole spectrum of this typology is defined by the end actors who are the composers and the consumers. The composers create knowledge and transform personal knowledge into organizational knowledge, while the consumers are those who use it. In between, there are owners, administrators, and performers. As an extension, we may include in this typology the citizens as end possible knowledge users. Also, we perform an analysis of the characteristics of all these actors with respect to values, objectives, methods, and results. The contribution of the present paper results from the new perspective we offer in understanding the mechanisms and the dynamics of the knowledge economy.
Looking into the Antecedents of the Transformation of IT Jobs. A Country-based Perspective
Authors: Moldoveanu Ion
Published: March 2024

Technology is changing at an exponential rate. As a result, it does have a disruptive life on society and our lives. It changes our personal lives, socialization, and interaction with people and businesses. Technology has changed and does continue to change the way we work. Along with the four industrial revolutions, many jobs have disappeared, more jobs have been created, and almost every job was transformed by automation. The 4th industrial revolution leading to Industry 4.0 is powered by artificial intelligence, robotics, Internet of things. The Information Technology (IT) industry and IT professionals primarily drive this transformation. While information technology specialists contribute with the technology they build to change their world, technology is transforming the profession responsible for this transformation. The paper looks at how digital transformation impacts the transformation of IT jobs, how government policies and managerial strategies impact the transformation of IT jobs and how employees and organizations are responding with investment in skills development. The research relies on a questionnaire-based survey with 132 Romanian IT professionals, students and computer science professors representing small and large organizations. Seven out of the nine hypotheses were supported by the data, confirming that digital transformation impacts the transformation of jobs, particularly IT jobs, and that this drives the need to build new technical and soft skills.
Pitfalls in Implementing the EU Whistleblower Directive
Authors: Scheu Harald Christian
Published: March 2024

In this paper, we focus on two conceptual problems associated with the EU Whistleblower Directive and point out issues that may undermine or even frustrate the successful implementation of the Directive in a national context. While fully acknowledging strong arguments for, and undeniable benefits of, speaking in favour of EU whistleblower protection, it has to be noted that a specific form of forced gold-plating calling for the extension of the material scope of protection may complicate the interpretation of the autonomous part of legislation and lead to legal insecurity. Moreover, new elements of whistleblower protection as introduced by the Directive diverge from the case law of the European Court of Human Rights. The introduction of higher standards of protection in favour of whistleblowers does not raise problems in relations between the state and the individual, but some EU rules may cause problems in horizontal relations between private individuals, since fair balancing of interests as required by Strasbourg jurisprudence may be not always guaranteed.

Authors: Lal Chaman , Tejyan Sachin , Singh Vedant
Published: March 2024

In this work, AA6061 aluminum alloy composites reinforced with industrial wastes, i.e., eggshell particles are fabricated. The stir casting technique was used to fabricate the Al6061 metal matrix composites. The AA6061 matrix contains 3, 5, and 7 wt.% eggshell particles as reinforcement. Mechanical characterization i.e., hardness, toughness, and tensile strength was examined of the eggshell particle-reinforced composites. According to the experimental findings, adding eggshell particles significantly increased the material's hardness, tensile strength, and toughness. Moreover, the sliding wear resistance improved by adding eggshell particles as reinforcement. ANNOVA results predict that sliding velocity and load are the dominant factors for the sliding wear of composites.

The Citarum watershed is a source of livelihood for communities in 13 cities and regencies in West Java and Jakarta. However, the Citarum River is considered one of the most polluted rivers in the world, prompting the central and local governments to implement conservation programs. For Tarumajaya Village, the conservation of the Citarum watershed starts from the Situ Cisanti area accompanied by the development of a tourism village to support the Citarum Harum Program. However, the existing participation is only seen from the government side, and there is no significant community participation in terms of communication and others directly in the process of developing this tourism village. Thus, this study aims to identify community involvement in the development of tourism villages to support the restoration of the Citarum watershed in the Upper Citarum Region. This qualitative study was conducted in Tarumajaya Village, Kertasari Sub-district, Bandung Regency. Primary data were obtained through non-participant observation and in-depth interviews, while secondary data were obtained from policy documents. Data analysis included data reduction, presentation, verification, and conclusion drawing. The research findings show that the development of creative tourism villages in Tarumajaya Village is carried out to support environmental preservation and has economic value for the welfare of the community, thus supporting public health. Tarumajaya Village community innovation products have economic value in tourism and show community involvement in supporting sustainable tourism development which is expected to improve public health.

Authors: Amilia Alya Nur , Rosita Noorma , Yusuf Helmy
Published: March 2024

Hydrolyzed collagen (HC) exhibits excellent anti-aging activity, but when applied topically, it faces limitations related to its physicochemical properties and low permeability to penetrate the skin. A system like liposomes is required. With the addition of cholesterol and Tween 80 surfactant to the liposome formulation, it is anticipated to enhance the characteristics and stability of the system in various combination ratios of Soy phosphatidylcholine: cholesterol: Tween 80, namely (F1= 4: 2: 1), (F2= 4: 1: 1), and (F3= 4: 1: 2). Characterization test results indicate that formula F3 exhibits the best characteristics, with respective values for particle size, PDI, zeta potential, and %EE being 63.26nm ± 0.73; 0.182 ± 0.011; 2.5mV ± 0.1; and 85.54% ± 0.20. Real-time stability test results, analyzed statistically using a Paired T-test, yield p-values for all three formulas (Sig 2-tailed) < 0.05, signifying a significant difference. Formula F2 demonstrates the smallest differences in particle size reduction and %EE. Hence, it can be observed that F2 stands out as the formula with the best characteristics and stability compared to F1 and F3.

This is a waste of energy if the government continues to allocate subsidies for kerosene. The PKM activity this time is in Sereal Village, Tambora District in West Jakarta. The area is a densely populated area and is a middle to lower class society. The community shows that there are some of them who still use kerosene for cooking purposes and there are still people who are afraid of installing LPG gas because they do not know how to install gas LPG safely. The purpose of PKM this time is to hold counseling and training for the installation of safety gas for the community. The method of implementation is to be held one day at the Tanah Sereal village office by inviting the surrounding community. Basically, the people are understand the use of natural gas conversion but they are reluctant to do so. Therefore, the IPTEKS description given to Tanah Sereal residents is to provide some posters or information papers on the safe installation of LPG gas so the people can understand this well. The implementing this PKM was welcomed enthusiastically by the residents at the local village office. In conclusion, it is expected that the community will have good knowledge in installing LPG gas and this training can be applied directly to the Tanah Sereal community.

These patients underwent Magnetic Resonance (MR) imaging along with detailed clinical history for differential diagnosis of cerebral hemiatrophy. Combining clinical and brain imaging findings streamlines diagnosing cerebral hemiatrophy, potentially reducing unnecessary tests and identifying the cause, like Rasmussen’s encephalitis, which can guide treatment (immunotherapy) and improve outcomes.
Thyroid volume and its correlation with thyroid function in Central India
Authors: Agrawal Alka , Bhandari Gaurav , Sahoo Ashish , Solanki Priya
Published: March 2024

Objectives

Due to its strong correlation with age, gender, anthropometric parameters, and geographic location, thyroid gland volume varies widely. Finding the reference range of a healthy individual’s normal thyroid gland volume has become crucial for every community. Thus, the public will be better able to grade goiter, and large-scale iodine monitoring initiatives will be guided by this. Ultrasound (US) eliminates the issues of overestimation of goiter prevalence and significant interobserver variability associated with palpation estimates, as it is more accurate than clinical examination in diagnosing enlarged thyroid glands.

This research aimed to use ultrasonography to determine reference ranges for total thyroid volume in the normal adult population in central India and to connect the results with thyroid function tests.

Material and Methods

A tertiary-care hospital hosted a prospective cross-sectional study. There were 410 healthy subjects in total. B-Grey scale imaging US was utilized to assess the overall thyroid volume by adding the volume of both lobes, which was calculated using the ellipsoid formula. In order to examine thyroid function, blood samples were obtained. Age-appropriate thyroid volume reference values were found.

Results

The average thyroid gland volume across all research participants was 6.90 ± 1.74 ml. The gland volume of males was considerably greater (7.30 ± 1.86 ml) than that of females (6.63 ± 1.61 ml) (P<0.001). In both genders, the right lobe’s volume was considerably higher than the left lobe’s (3.76 ± 0.96 ml vs. 3.14 ± 0.89 ml, P < 0.001). There was no discernible relationship between thyroid function tests and gland volume.

Conclusion

We made an effort to help set the reference values for our community, but more extensive research is needed to set the thyroid gland volume reference values for the entire country.

The advent of severe acute respiratory syndrome coronavirus (SARS-CoV) during the latter half of 2019 brought a new face to the global medical scenario. With a rising trend in COVID infectivity and the concomitant use of steroids in its management, it emerged as a risk factor for the development of acute invasive fungal infections of the paranasal sinus in these patients. In India, the medical scenario turned towards a rise in the number of fulminant mucormycosis infections in post-COVID patients. This infection caused rapid invasion via the perineural pathway and extensive angioinvasion, which led to an increase in morbidity and mortality. Early diagnosis of this infection became crucial to ward off any preventable complications. This pictorial review focuses on the varied early and late imaging appearances on Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), keeping the focus on MR imaging to make the diagnosis, to know the extent of the infective process, diagnose early complications and for surgical planning.

Double aortic arch (DAA) is a rare cause of esophageal compression. We present a case of a seven-month-old male infant who presented with complaints of dysphagia and wheezing during crying. Computed tomography angiography (CTA) revealed a co-dominant double aortic arch forming a complete vascular ring around the trachea, causing its mild compression. Posteriorly, the aortic arch was seen, causing severe compression of the esophagus. The patient underwent double aortic arch repair and had an uneventful post-operative course, with resolution of the dysphagia.
Body size modulates demographic patterns of top predators and their native and invasive prey: A biomathematical approach
Authors: Campillay-Llanos William , Pinto Manuel , Osorio Christian
Published: March 2024

The arrival of invasive species in native communities impacts the structure and functioning of ecosystems, and is considered a critical indicator of loss of biodiversity. Exploring the effects of new species in communities presents challenges addressable through theoretical ecology. Species body size not only shapes trophic relationships, but may also impact predator success and facilitate species coexistence. However, little attention has been paid to the effects of differences in species body size on interactions between native and invasive primary consumers, which could be relevant to their coexistence with higher-level predators. Our aim is to investigate demographic patterns using a dynamic, mechanistic model of two age-structured primary consumers (one invasive and one native) sharing a plant resource and preyed upon by a common predator. In our model, we highlight three crucial phenomena: the structuring of primary consumers into adults and juveniles, reproduction occurring in discrete pulses, and the seasonal addition of new individuals to the population. Hence, the success of one species over the other relies on its reproductive capacity to incorporate individuals in each reproductive cycle. Our simulations reveal that abundance patterns are influenced by body size, suggesting that changes in predator body size could serve as key indicators of shifts in community structure.

El gatuzo, Mustelus schmitti (Carcharhiniformes, Triakidae) es un tiburón endémico del Océano Atlántico Sudoccidental y está catalogado como en peligro crítico por la UICN. La edad y el crecimiento de M. schmitti se estudiaron utilizando cortes sagitales de vértebras de 102 hembras y 121 machos capturados incidentalmente por la pesquería de langostino y por pescadores deportivos costeros en la Patagonia Central (43-44° S). Las edades máximas observadas para hembras y machos fueron 18 y 16 años, respectivamente. Se ajustaron siete modelos de crecimiento (longitud a la edad). El modelo de dos fases de von Bertalanffy presentó el mejor ajuste para hembras y machos. No se encontraron diferencias significativas en el crecimiento entre sexos. Los parámetros fueron longitud asintótica (L∞)=916 mm; coeficiente de crecimiento (k)=0.12 años-1; edad a la que se produce la transición entre las dos fases de crecimiento (th)=5.26 años; talla al nacer (L0)=283.03 mm, y longevidad (tmáx)=21.92 años. La edad de madurez sexual se estimó en 8.86 y 8.48 años para las hembras y los machos, respectivamente. M. schmitti presenta un crecimiento moderado, una vida relativamente larga y una edad de madurez tardía, similar a otros elasmobranquios caracterizados como extremadamente vulnerables.

Nowadays, remote voting systems and applications become very popular, but they have some drawbacks, especially in terms of anonymity. The aim of the paper is to create a scheme for developing a reliable anonymous remote voting system. The methodology for designing such a scheme is based on the algorithm of blind ballots digital signature. This algorithm is one of the effective ways to generate and sign a voting ballot, where its encrypted voting results are transmitted to the ballot server without any information about user. A secret channel protocol was created to anonymously transfer ballots from voters to a server. This article proves the reliability of this method and also presents a recommended method for securely storing ballots as block chain transactions. In addition, possible threats to the security of the system were investigated and analyzed and there were presented possible ways to prevent them. As the result of this work, an effective scheme for creating an anonymous remote voting system with relatively small number of participants was described. Moreover, the reliability of the presented system was analyzed and it was demonstrated that the system of anonymous remote voting is not affected by possible vulnerabilities discovered during the investigation. As a result of the performed research, it was shown that the presented anonymous remote voting scheme is a good alternative to traditional voting and other similar systems.

Despite the prevalence of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) in Niger Delta's crude oil regions, comprehensive research on their concentrations and combined risks in crude oil-contaminated soils is lacking. Our study focused on examining the concentration, source, spatial distribution, and health risk of 16 PAHs and 9different HMs in soils across a gradient of Niger Delta area Nigeria. The objective was to gain a comprehensive understanding of the HMs and PAHs' behavior in the environment and their potential impact on human health. The mean total concentrations of 16 PAHs (Σ16PAHs) were 779.58 ng/g for upland area, 749.46 ng/g for mid-slope area, and 679.37 ng g-1 for Low-land. The concentration of the HMs followed the order of Cu > Cd > Ni > Pb > Cr > Fe > Mn > Zn > Co, with Cu, Cd, Ni, and Pb exceeding the permissible levels. The study areas displayed varying concentrations of NO3-, PO42-, SO42- Ca, Na, and K, with some levels exceeding acceptable values, possibly influenced by crude oil contamination and the use of fertilizers. In the Niger Delta regions, the primary sources of soil PAH contamination include crude oil spills, natural crude oil seepage, and coal combustion. With this, the government of Nigeria should strengthen soil contamination monitoring, enforce spill regulations and promote eco-friendly farming.
