Coastal Vulnerability Assessment Along The North Java Coastlines-Indonesia
Authors: Handiani Dian N. , Heriati Aida , Suciaty Fitry
Published: November 2022

The north coast of Java is an area with very diverse maritime activities. These high activities threaten the ecosystem and environmental sustainability. Several areas already experience environmental degradation and most of the threats come from ocean pollution, coastal erosion, continuous tidal flood (rob), and coastal land subsidence. Furthermore, the coastal degradation is worsened by climate change which may cause the area more vulnerable to disaster. This study aims at evaluating the coastal vulnerability using weighted coastal vulnerability index (CVIw). The method calculates coastal vulnerability by weighting physical coastal parameters using Analytical Hierarchy Process (AHP). CVIw calculation result shows that the vulnerability is dominant at high (39%) and very high (51%) classes. The high vulnerability occurs in Tangerang, Bekasi, Brebes, Demak, Jepara, Pati, and Rembang Regencies. Meanwhile, very high vulnerability takes place in several regencies: Serang, Karawang, Subang, Indramayu, Cirebon, Tegal, Kendal, Semarang, and Gresik. The parameters of relief, coastal features, tidal range and shoreline give contribution more in coastal vulnerability besides lithology, sea level change, and wave height. Identifying vulnerability in these areas might help local governments to prioritize their action plan in coastal disasters mitigation.

Seagrasses are an essential component of the coastal environment with provide many ecosystem services beneficial to humans. Understanding the pattern of dispersal of segrasses is important for conservation management. The aimed of this research was to analyze the seed dispersal of the seagrass Enhalus acoroides in the Marine Protected Area of Biawak Islands, Indramayu, based on hydrodynamic modelling. Oceanographic data were downloaded from several open acces website and location of seagrasses based one insitu observation. Then, oceanographic parameters and seed traits were used to develop the particle trajectory model. Our analysis showed that the seafloor’s depth around the islands varied, ranging from 8 m to 48 m. The seed dispersal was strongly influenced by alternating tidal currents (reversing current). The particle trajectory showed that most of the seeds would be transported outward away from each source in the islands, and they settled in deeper areas further from the coast of the islands. This result indicates that the seagrass population in Biawak Islands might depend predominantly on vegetative recruitment, which is slow. This may be related to the low seagrass canopy cover in Biawak Islands.
Vowel convergence does not affect auditory speaker discriminability in humans and machine in a case study on Swiss German dialects
Authors: Pellegrino Elisa , Kathiresan Thayabaran , Dellwo Volker
Published: November 2022

In this study, we examined whether the convergence in interlocutors’ vowel acoustics leads to decreasing discriminability between interlocutors’ voices. Ten pairs of Grison and Zürich German speakers produced lexical items before and after dialogue interactions with evidence of vowel convergence in post-dialogue productions. In Experiment 1, native and non-native Swiss German listeners discriminated pairs of speakers whose speech was obtained pre- and post-dialogue. Results showed that listeners’ sensitivity (A’) was higher for native than non-native listeners, but comparable for pre- and post-dialogue recordings. The observed negative correlation between voice discrimination and the acoustic distance in formant space was mainly driven by a single speaker pair. In Experiment 2, the speaker recognition performance of an i-vector-based software was compared in pre- and post-dialogue speech. Results revealed no difference in the system performance between the two conditions. The findings suggest that vowel convergence does not compromise voice discriminability under the given experimental conditions.
THERMAL AND MASS BEHAVIOR PREDICTION OF ADSORPTION SOLAR REFRIGERATOR OPERATING IN CONTINUOUS MODE
Authors: Safa Abdelkader , Hamid Abdelkader
Published: November 2022

In this study, we performed a thermal analysis of an adsorption refrigeration system driven by a parabolic trough collector using an activated carbon AC-35/ammonia adsorption pair under the following operating conditions: Ta = 25°C, Tev = -5°C, and 30 < Tg < -120°C. The main objectives were to develop a mathematical model that predicts the spatio-temporal evolution of the state variables (i.e., the temperature, mass, and pressure) at the level of an adsorption solar refrigeration system operating in continuous mode and to investigate the influence of the main parameters on the thermal performance coefficient of the studied machine. This model is based on the energy and mass conservation equations in a porous medium. The Dubinin-Astakhov equation was used to describe the adsorption kinetics. The obtained differential equations system is highly nonlinear and was solved during both the heating and cooling phases, by the fourth-order Runge-Kutta finite-difference method. The results of the analysis led us to conclude that the proposed model satisfactorily describes the adsorption kinetics and both the condensation and generation temperatures have a substantial impact on the thermal coefficient of performance (COPh) of the cooling system. In addition, the COPh reached by our cooling system was 0.63.

Significance Statement

Several reports have described glomerular disease relapse after coronavirus disease 2019 (COVID-19) vaccination, but without proper controls, determining whether this association is real or due to chance is not possible. In this population-level cohort of 1105 adult patients with stable glomerular disease, a first dose of a COVID-19 vaccine was not associated with relapse risk; however, receiving a subsequent vaccine dose was associated with a two-fold higher risk of relapse. The increase in absolute risk associated with vaccination was low (1%–5%), and the majority of affected patients did not require a change in immunosuppression or biopsy. These results represent the first accurate assessment of the relative and absolute risks of glomerular disease flare associated with COVID-19 vaccination and underscore the favorable risk-benefit profile of vaccination in patients with glomerular disease.

Background

Although case reports have described relapses of glomerular disease after COVID-19 vaccination, evidence of a true association is lacking. In this population-level analysis, we sought to determine relative and absolute risks of glomerular disease relapse after COVID-19 vaccination.

Methods

In this retrospective population-level cohort study, we used a centralized clinical and pathology registry (2000–2020) to identify 1105 adult patients in British Columbia, Canada, with biopsy-proven glomerular disease that was stable on December 14, 2020 (when COVID-19 vaccines first became available). The primary outcome was disease relapse, on the basis of changes in kidney function, proteinuria, or both. Vaccination was modeled as a 30-day time-varying exposure in extended Cox regression models, stratified on disease type.

Results

During 281 days of follow-up, 134 (12.1%) patients experienced a relapse. Although a first vaccine dose was not associated with relapse risk (hazard ratio [HR]=0.67; 95% confidence interval [95% CI], 0.33 to 1.36), exposure to a second or third dose was associated with a two-fold risk of relapse (HR=2.23; 95% CI, 1.06 to 4.71). The pattern of relative risk was similar across glomerular diseases. The absolute increase in 30-day relapse risk associated with a second or third vaccine dose varied from 1%–2% in ANCA-related glomerulonephritis, minimal change disease, membranous nephropathy, or FSGS to 3%–5% in IgA nephropathy or lupus nephritis. Among 24 patients experiencing a vaccine-associated relapse, 4 (17%) had a change in immunosuppression, and none required a biopsy.

Conclusions

In a population-level cohort of patients with glomerular disease, a second or third dose of COVID-19 vaccine was associated with higher relative risk but low absolute increased risk of relapse.
Rising from its ruins? The Southern African Development Community (SADC) Tribunal
Authors: Shumba Tapiwa
Published: November 2022

The Tribunal of the Southern African Development Community (SADC) was established to ensure adherence to and the proper interpretation of the provisions of the SADC Treaty and its subsidiary instruments, and to adjudicate upon such disputes as might be referred to it. However, since its establishment, it has had a troubled history. After the rulings it made against the Government of Zimbabwe in the landmark Campbell land seizures case, the Tribunal's operations were unceremoniously suspended. This was followed by a process to revise its mandate, one that ultimately condemned it to paralysis and ruin. The new 2014 Protocol on the Tribunal, meant to revise the mandate of the Tribunal to confine it to hearing disputes involving states only, has been criticised as an attempt to undermine the rule of law and human rights in the region. Since the adoption of this 2014 Protocol by the SADC Summit, stakeholders have mobilised regionally to resist its ratification by member states. In particular, lawyers in SADC countries are embarking on legal petitions to reverse the Protocol and promote the revival of the Tribunal in terms of its old mandate. So far, there have been victories in these cases in two influential SADC member states, South Africa and Tanzania. However, it remains important to assess the significance of these developments. As such, the article raises the question: Is the Tribunal rising from its ruins?
An improved pillar design methodology
Authors: Jessu K.V. , Spearing A.J.S. , Sharifzadeh M.
Published: November 2022

Empirical pillar design methods are commonly used in the mining industry. The parameters within which these methods are valid are frequently unknown to the user or ignored. In addition, empirical design may not consider essential parameters such as blasting effects, orebody dip and the presence of geological structures, which all adversely affect the stability of the pillars. This can result in potentially serious pillar design strength over-estimates. Although the commonly based tributary area method is generally conservative, as the spans are seldom that large relative to the depth, failing to consider other relevant parameters can result in errors. Problems associated with an under-designed pillar can range from a local pillar collapse to a catastrophic chain reaction collapse (or run). Over-designed pillars are generally safe but reduce the extraction of the orebody, thus adversely affecting the profitability of the mining operation. We used laboratory tests and numerical modelling to understand the effects of pillar orientation, blasting and the presence of discontinuities on pillar strength. Reduction factors were developed with these models to be implemented in conjunction with the existing empirical pillar design methods. For any pillar or mine design, once it is implemented, the actual performance of the system must be checked regularly by observation and monitoring and adjusted if needed. The pillar design approach outlined in this paper can better optimize the pillar mining method by considering other generally ignored but important parameters, thus improving safety, productivity, and economic aspects.
A discrete event simulation approach for mine development planning at Codelco's New Mine Level
Authors: Soto I. , Anani A. , Cordova E.
Published: November 2022

The new caving megaprojects that are planned to go into production in the next decade have scheduled horizontal developments at very high rates, which are difficult to achieve. Research has been conducted that seeks to model the construction times for underground developments to determine the feasibility of achieving the planned rates. However, these previous attempts do not consider all the operational aspects that make up the mine development cycle. Here, we present a discrete event simulation (DES) model that individualizes each unit operation of the development cycle to determine the construction rates that new projects will be able to attain. The developed model was applied to the New Mine Level (NML) of the El Teniente Division (DET). The results indicate that it would be impractical to achieve the advance rates scheduled in the original plans if the unit operations of the mine continue to be executed using the status quo. The metres developed after six years in the sections analysed can be significantly improved by changing the maintenance strategy for the equipment (457 metres increase), orepass availability (194 metres increase), and the initial planning sequence (1 598 metres increase). It is recommended that the mine implements a flexible maintenance strategy, defines a strategy to ensure and increase orepass availability to contractors, and makes use of current simulation tools for a more robust development sequence planning.
More is exponentially less: marginal utility in critical care research
Authors: Leite Rafael Olivé
Published: November 2022

BACKGROUND: Randomized clinical trials (RCT) in critical care mostly return negative results. The research community discusses strategies to improve RCTs design. METHODS: This paper presents a theoretical framework based on marginal utility to treat the problems of hypothesis generation and treatment effects valuation and presents recently published high-quality studies as instances where such a framework predicts irrelevant findings. RESULTS: Blindness to marginal utility, i.e., inobservance of the marginal utility of the proposed intervention, is common in critical care RCTs. CONCLUSION: Critical care RCTs are usually blind to marginal utility and are, therefore, prone to produce irrelevant findings.
SVF Isolation and Immunophenotyping using Flow Cytometry in Leprosy Patients v1
Authors: P. Sirait Sondang
Published: November 2022

Adipose derived stromal vascular fraction (SVF) contains a heterogeneous population of mononuclear cells, progenitor cells and about 1-10% are mesenchymal stromal cells. These cells are an ideal candidate for regenerative medicine for peripheral neuropathy. Leprosy is a disabling disorder with neuropathy, usually with consequences of permanent disability of the extremities. Before we could inject the SVF, we need to learn whether the SVF is appropriate to be used for neuropathy treatment using the flow cytometry characterization. Liposuction was done to four leprosy patients and adipose tissue was processed into SVF with a closed system. Following the process, the SVF were characterized and counted the CD73, CD90, CD34, CD45, Lin-Negatif, and CD105 cells using flow cytometry, cell counting, sterility and presence of mycobacteria. The process was done by ProStem using a traditional flow cytometer, without blocking and negative isotypes. The expected results from these protocols are the appropriate amount of mesenchymal cells needed to meet the IFATS and ISCT standards for SVF.
Putting on Intersectional Glasses: Listening to the Voice of the Vulnerable
Authors: Subasi Singh Seyda
Published: November 2022

Many share the concern that the Covid-19 pandemic has had devastating impacts on the vulnerable who are already disproportionately at risk of social exclusion. The health-related risks that the pandemic entailed and the challenges that resulted from the associated measures have led to new vulnerabilities for specific groups such as persons with disabilities, persons from a (forced) migrant background, and women/girls. This article will discuss the complexity of the multiple vulnerabilities during the Covid-19 pandemic by relying on data collected from immigrant women with disabilities. To this end, data from two women with disabilities who are members of the historically marginalized Turkish immigrant group in Austria were analyzed with regard to their experiences during the pandemic. Their accounts are analyzed from an intersectional perspective in order to document the effects of peri-post-pandemic measures on the lives of people with multiple disadvantages. The interviews and audio diaries by two immigrant women with disabilities recorded over seven months are used to delve into latent oppression structures and overlapping mechanisms of difficulties embedded in their experiences. The findings show how the multiple identities and struggles of the two women were affected during the pandemic by building upon each other.
Adoption features and approach for UWB Wireless Sensor Network based on Pilot Signal assisted MAC
Authors: Ayub Kamran , Zagurskis Valerijs
Published: November 2022

In the field of wireless sensor network (WSN), Pilot Assisted Transmission (PAT) is a new concept. In our previous research, a mac layer algorithm called, “PA-MAC” was designed, which exclusively uses PAT technique for the medium access control. The performance of PA-MAC was evaluated under multi-hop and single hop WSNs. It was excellent under a single hop structure (i.e. network with a few nodes). But when it was evaluated for the dense network topology, the performance seriously declined. It was noted that the two main reasons of performance degradation are interference and transmission range. Technically there are two ways to tackle a dense network traffic problem. One is to use the multi-hop structure and the other one is clustering. In this research paper, clustering based adoption strategy is examined, and beside dynamic clustering approach multiple optimization features (i.e., clustering formation based on transmission range, dynamic cluster head selection and use of the Volterra code for the mitigation of interference) are added and tested. Collectively these adoption features have not only improved the media access performance but also optimized the network lifetime.In the field of wireless sensor network (WSN), Pilot Assisted Transmission (PAT) is a new concept.

Energy Aware Multipath Routing Protocol for Cognitive Radio Ad Hoc Networks
Authors: Kamruzzaman S. M. , Fernando Xavier , Jaseemuddin Mohammad
Published: November 2022

Cognitive radio networks (CRNs) emerged as a paradigm to solve the problem of limited spectrum availability and the spectrum underutilization in wireless networks by opportunistically exploiting portions of the spectrum temporarily vacated by licensed primary users (PUs). Routing in CRNs is a challenging problem due to the PU activities and mobility. On the other hand, energy aware routing is very important in energy-constraint CRNs. In addition, it is crucial that CR users efficiently exchange data with each other before the appearance of PUs. To design a robust routing scheme for mobile CR ad hoc networks (CRANs), the constraints on residual energy of each CR user, reliability, and the protection of PUs must additionally be taken into account. Moreover, multipath routing has great potential for improving the end-to-end performance of ad hoc networks. Considering all these evidences, in this paper, we propose an energy aware on-demand multipath routing (EOMR) protocol for mobile CRANs to ensure the robustness and to improve the throughput. The proposed routing scheme involves energy efficient multipath route selection and spectrum allocation jointly. The simulation results show that our approach improves the overall performance of the network.

Published: November 2022

Cranioplasty is used for skull defects, involving lifting the scalp and restoring the contour of the skull with the original skull piece, titanium mesh, or solid biomaterial. Additive manufacturing (AM) technology, known as three-dimensional (3D) printing, is now utilized by medical professionals to develop customized replicas of tissues, organs and bones, offering a valid option with perfect anatomic fitting in the individual and skeletal reconstruction. Here, we report a case that underwent titanium mesh cranioplasty 15 years ago. The poor appearance of the titanium mesh weakened the left eyebrow arch and resulted in the formation of a sinus tract. Cranioplasty was performed using an additively manufactured polyether ether ketone (PEEK) skull implant. PEEK skull implants have been successfully implanted without any complications. To our knowledge, this is the first reported case of direct use of fused filament fabrication (FFF)-fabricated PEEK implant for cranial repair. The FFF-printed PEEK customized skull implant could possess simultaneously with adjustable material thickness and more complex structure, tunable mechanical properties, and low processing costs compared with traditional manufacturing processes. While meeting clinical needs, this production method is an appropriate alternative for promoting the use of PEEK materials in cranioplasty.

Healthy Neuroticism, Daily Physical Activity, and Daily Stress in Older Adults
Authors: Lozinski Tristen , Yoneda Tomiko , Hofer Scott , Rush Jonathan
Published: November 2022

People are typically less physically active when experiencing stress, an unavoidable aspect of life. Since physical activity has been associated with health benefits, it is important to understand what influences physical activity during stress. Research has demonstrated that individuals who are high in conscientiousness are more physically active; however, studies that have examined physical activity among people high in neuroticism have yielded mixed findings. Healthy neuroticism, a term used to describe individuals high in conscientiousness and neuroticism, may explain these mixed results. While individuals low in conscientiousness and high in neuroticism may become overwhelmed, stress may motivate people high in healthy neuroticism to be physically active as an investment in their future. We assessed older adults’ (N = 60; Mage = 70.72; 76.70% cisgender women) personality at baseline as well as daily physical activity and daily stress over 14 days. Regression analyses investigated whether daily stress predicted daily physical activity and whether healthy neuroticism moderated the physical activity-stress association. Ultimately, this study found that daily stress did not predict daily physical activity; as stress increased, individuals higher in conscientiousness were less physically active, while individuals lower in conscientiousness were more active. These findings were inconsistent with our predictions and previous research. Consequently, we propose future research directions and potential explanations for these unforeseen findings.
FM 3-24 and Religious Literacy in American Military Operations in the Middle East
Authors: Olson Samantha
Published: November 2022

In August 2021, the Taliban’s success in Afghanistan shocked American citizens and foreign policy analysts. Many counterinsurgency experts sought to explain this phenomenon by focusing on tactical and strategic military failures; however, such explanations often neglected to investigate the religious literacy of American troops engaged in counterinsurgency operations in the Middle East. By considering the treatment of religious literacy in General David Petraeus’s landmark field manual, FM 3-24, a startling degree of religious illiteracy is revealed within counterinsurgency operational protocols. While a historically and culturally focused “civilizational approach” is often proposed by foreign policy analysts as a potential solution to the problem of religious illiteracy in counterinsurgency operations, this approach also falls short of addressing the complex realities that confront American “liberators,” whom locals often perceive to be foreign invaders. This article therefore addresses the disconnect between American military strategy, foreign policy, and the tactical realities encountered by military personnel stationed in the Middle East. Resultantly, this article argues that improved mandatory religious literacy training for American troops is critical not only for conducting successful operations in the Middle East but also for ending, rather than reinvigorating, conflicts abroad.
BURNOUT AMONG RESIDENTS OF GENERAL SURGERY: WORK-LIFE BALANCE, SOCIAL SUPPORT, AND BURNOUT AMONG RESIDENTS OF GENERAL SURGERY
Authors: Anjum Wahida , Mahmood Sarfraz , Qazi Zainab , Ishaq Ghulam , Qadeer Abdul
Published: November 2022

Purpose: Postgraduate medical students or residents are candidates who gain rigorous specialized training in any field of medical science. The study attempted to explain how work-life fit and perceived social support minimize burnout in public hospital general surgery units.

Method: Explanatory, cross-sectional, and quantitative research methods were employed. A questionnaire was administered to 120 respondents using purposive sampling. Besides reliability and validity testing, inferential statistics were used to evaluate data and test hypotheses.

Principal Findings: Work-life fit and perceived social supports affect emotional tiredness in responders. However, perceived social support and emotional weariness outweigh work-family balance and emotional exhaustion. Burnout is predicted by the number of children, gender, work-life balance, work-life interference, and personal life interference.

Implications: The current study helps us understand the process that affects the professional efficacy of medical professionals. Despite their high cognitive capacity, they were victims of depersonalization, emotional tiredness, and burnout. Therefore, it is crucial to successfully address surgeon burnout to enhance patient care.

Novelty: The study has novel findings for exploring the link between work-life balance, social support, and burnout in the cultural settings of Pakistan. It was not comprehensively investigated in our traditional healthcare system which is lacking in internal and external rewards therefore a complete investigation of the matter is required. Thus, these findings will enrich scientific understanding to further study these topics.

SOME ASPECTS OF THE CIVIL LIABILITY OF THE PARTIES UNDER THE BANK ACCOUNT AGREEMENT
Authors: Sviatoshniuk S. S.
Published: November 2022

The article is devoted to the study of theoretical aspects of the civil liability of the parties under the  bank account agreement. The article is devoted to  the study of the characteristic features of civil liability under a bank account agreement. Characterizing the specifics of civil liability under a bank account  agreement, it is worth taking into account the general provisions on civil liability specified in the  Civil Code of Ukraine. Special attention is paid to the investigation of the parties’ responsibility under the  bank account agreement.
In the article there are defined civil liability through  the category of «sanction», that is, under civil liability should be meant certain legal consequences that  follow for the offense committed, and are  implemented with the help of influence measures,  expressed in negative property consequences for  offender.
There are also defined that banking activity is always associated with risk, banks ensure the circulation of  money in society, and the line between the liability of banks for personal funds and the funds of  depositors of the latter is very «flexible» - and  therefore, the limitations on the liability of banks in the implementation of the latter offenses in the  implementation settlement operations - must be  taken into account in terms of banks’ responsibility  when carrying out settlement operations.
The article also notes that the amount of  responsibility to the client is much smaller compared to the bank. As mentioned above, the essence of the  contract under study is the provision of banking  services, and their timely payment is the client’s  responsibility and the main indicator of the  appropriateness of the contract.
It is also noted that the illegal behavior of the parties to the bank account agreement can be expressed  both in certain actions and in inaction. Illegal  behavior «corresponds» to those obligations of the  bank and the client, which are provided for by  regulatory acts and terms of the contract and for the non-fulfillment of which the law or contract provides  for civil liability.

Advancements in conceptualisation and studies on academic entrepreneurship phenomenon
Authors: Nowak-Mizgalska Hanna
Published: November 2022

Academic entrepreneurship is a specific type of entrepreneurship relating to science and knowledge, the role of universities and the commercialisation of research results. The aim of the chapter is to present the current state of advancement of research on this issue in international literature. In particular, the aim is to present the way of conceptualizing this phenomenon in scientific research, as well as the methods used and theoretical approaches taken by the authors. A review of the literature indicates the evolution of the concept of academic entrepreneurship and the expansion of the scope of its application in scientific works. In a narrow sense, this term is mainly used to describe activities undertaken by scientists based on academic knowledge and the technology obtained from university resources. The broader approach also covers the development of entrepreneurial attitudes among students through entrepreneurship education, support for the creation of start-ups and wider cooperation with stakeholders in order to build an ecosystem for the development of academic entrepreneurship. The effects of academic entrepreneurial activities in a new, wider perspective are assessed from the point of view of the value created for society and the economy.
Academic entrepreneurship as a process
Authors: Szulczewska-Remi Aleksandra
Published: November 2022

Academic entrepreneurship is the process by which knowledge spills over from universities and other research institutions in order to be commercialised. Because the development of this process model requires a holistic and integrative perspective, the main objective of this chapter was to develop a process model of academic entrepreneurship. Based on a systematic review of academic literature data, 68 articles were selected, out of which 10 papers were further synthesized for the development of a process model so as to understand academic entrepreneurship. It was assumed that this entrepreneurial process consists of opportunities identification coming from university innovation that is perceived as a mechanism for knowledge spillover with regards to knowledge spillover theory of entrepreneurship. These opportunities are leveraged by the entrepreneurial resources and reconfigured to develop entrepreneurial competences according to the theory of entrepreneurship that consequently lead to knowledge and technology commercialisation. In this way, the proposed process model of academic entrepreneurship presents innovation as created in the university environment and driven by entrepreneurship to create value for knowledgebased economies.

Published: November 2022

The aim of the research is to analyse selected attitudes related to entrepreneurship and to present their significance assessment according to students of economic faculties. The empirical basis is built upon the results of the research conducted in March 2021 on a group of 270 students of the Poznań University of Economics and Business. As part of the questionnaire and using the 5-point Likert scale, the respondents assessed various features, skills and abilities that, according to the respondents, are key in the context of an entrepreneurial attitude. In addition to the general statistical analysis of the response, a factor analysis was also carried out that aims to reduce the number of variables to a few, the most important ones that highly describe the analysed problem. Based on the research conducted, it can be concluded that from the students’ perspective, the entrepreneurial attitude profile consists of a combination of personality types such as precursor, creator, rival, individualist, risk-taker. The research was limited because it was based on one academic centre (Poznań University of Economics and Business). Extending the research to other areas of higher education (e.g. law, medicine, psychology, computer science, mechanics) would allow the conclusion to be drawn on a wider scale and provide more insight into the nature of the phenomenon. The value of this study lies in the fact that it presents a coherent framework to explain the diverse characteristics of entrepreneurial attitudes in the business school environment.

The research objective was to present the significance of the coronavirus pandemic in the context of starting a business, by business students. The empirical basis was fabricated upon the results of a survey conducted at the Poznań University of Economics and Business. The research was dynamic and conducted in two stages: in February 2020 (just before the first lockdown in Poland) wherein 243 students were surveyed and in March 2021 (a year after the first lockdown), in which 270 students were surveyed. The respondents were asked, among other issues, to describe their professional experience, as well as perspectives and plans concerning setting up and managing their own company. In addition, factor analysis was used to deepen the findings. The pandemic has significantly influenced students’ professional plans, including, above all, an increased desire to start their own business. In addition, of particular importance for students at the beginning of their professional career is the flexibility and ease of adaptation to changing conditions in the business environment. The research was limited because it was based only on students of Poznań University of Economics and Business. Extending the research to other social groups such as students of other universities, the unemployed, graduates of technical / vocational schools, economically active people, elderly people, etc. would allow to explore the reasons and conditions for setting up a business. The article shows how students’ perspectives and attitudes towards setting up their own businesses have changed. The results of the research may be of particular interest to entities such as public administration, local governments, labour offices and all institutions which are focused on education and career shaping.

Data analysis and processing skills are currently required by a multitude of job offers and cover a wide variety of applications. Although mostly shaped by the development of new technologies, programming languages and libraries, they are a necessity in the world of digital economy and entrepreneurship. A multitude of reports by large consulting companies such as Deloitte predict a sharp increase in demand for data science and AI roles in the future of not only the IT sector, but also the entire economy. The following questions arise: “What skillset do these innovators that use artificial intelligence and advanced analytical skills have?” and “What skills and requirements truly make a data scientist and are they are any different to that of data analysts, data engineers or software developers and programmers?”, moreover, “What is the demand for these specialists and are the university programs educating future specialists in this field or are the skills too new and need to be taught solely by business practice?” . To answer these questions, this article applies Natural Language Processing (NLP) techniques of machine learning to characterize and extract from the offers key skills important for data centred roles. The research was carried out on a preprocessed sample of 72 thousand job offers from the IT sector posted in 2019. A SVM linear classifier was applied to extract the most distinguishing technical skills and characterize the possibility of the automated classification of job postings, which resulted in about 85% precision and recall values for classifying data analyst, data scientist and data engineer roles and about 90% for classifying python developer roles.

Published: November 2022

This work presents the preparation of a reference material for Fe, Ca, Ni and Si in order to ensure the quality of the analysis of these elements in routine samples of carbonaceous materials in a aluminum industry. The sample was fractioned and bottled for homogeneity and stability studies before being shipped to interlaboratory certification. Then, we sent a bottle for each one of seven participating laboratories to define the reference values. The results of concentration for Fe, Ca, Ni and Si, after outlier exclusion were 589.1 ± 25.3, 142.9 ± 12.0, 178.1 ± 9.3 and 134.2 ± 6.6, respectively. Finally, we applied the technique of z-score, to evaluate the performance of the participating laboratories. After the results of this study we can conclude that the carbon material can be used like reference material for in-house control of Fe, Ca, Ni and Si analyses.
