Hybrid Threats – Means of Destabilization of Law and Order in Modern Democratics Societes. Idea and Methodology of Proposed Research
Authors: Chodak Paweł , Krassowski Krzysztof , Wierzchowski Tomasz
Published: July 2022

Threats are one of the most serious threats to the legal order of a democratic state. Their non-linear, asymmetric nature makes them more dangerous than other threats to the legal order. The use of multifaceted measures as a weapon disrupts, above all, the legal order of the state. Hybrid threats rely heavily on non-military domains. Civilian populations are central to the hybrid threat scenarios as sources for potential socio-political vulnerabilities and as targets for non-military threats and attacks, not least disinformation campaigns. A significant part of the hybrid threat phenomena is psychological. Actors targeting communities/societies to exacerbate weaknesses do not necessarily create social vulnerabilities themselves but make use of divisions that already exist in civil society. Using disinformation, populations are targeted and used as potential weapons within the state/society in question. This paper shows a concrete scientific approach to the study to of this issue.

Published: July 2022

Background:

The SOMAscan assay has an advantage over immunoassay-based methods because it measures a large number of proteins in a cost-effective manner. However, the performance of this technology compared to the routinely used immunoassay techniques needs to be evaluated.

Objective:

We performed comparative analyses of SOMAscan and immunoassay-based protein measurements for five cerebrospinal fluid (CSF) proteins associated with Alzheimer’s disease (AD) and neurodegeneration: NfL, Neurogranin, sTREM2, VILIP-1, and SNAP-25.

Methods:

We compared biomarkers measured in ADNI (N = 689), Knight-ADRC (N = 870), DIAN (N = 115), and Barcelona-1 (N = 92) cohorts. Raw protein values were transformed using z-score in order to combine measures from the different studies. sTREM2 and VILIP-1 had more than one analyte in SOMAscan; all available analytes were evaluated. Pearson’s correlation coefficients between SOMAscan and immunoassays were calculated. Receiver operating characteristic curve and area under the curve were used to compare prediction accuracy of these biomarkers between the two platforms.

Results:

Neurogranin, VILIP-1, and NfL showed high correlation between SOMAscan and immunoassay measures ( r > 0.9). sTREM2 had a fair correlation ( r > 0.6), whereas SNAP-25 showed weak correlation ( r = 0.06). Measures in both platforms provided similar predicted performance for all biomarkers except SNAP-25 and one of the sTREM2 analytes. sTREM2 showed higher AUC for SOMAscan based measures.

Conclusion:

Our data indicate that SOMAscan performs as well as immunoassay approaches for NfL, Neurogranin, VILIP-1, and sTREM2. Our study shows promise for using SOMAscan as an alternative to traditional immunoassay-based measures. Follow-up investigation will be required for SNAP-25 and additional established biomarkers.
Using the integrated neural network of radial basis function (RBF) via optimization algorithms to estimate pile settlement range
Authors: Jiang Ruiyang
Published: July 2022

The Pile motion seems to be one of the most critical in pile failure that requires appraisal before installing piles. The variables to estimate the Pile Settlement parameter, there are several methods. Among existing theoretical ways to investigate the pile movement mathematically, most studies have tried to model the piles’ settlement overloading period using artificial intelligence. Thus, this research has used the Artificial Neural Network to have the actual status of pile motion vertically over the loading periods dynamically and statically. Therefore, the present research has utilized the Radial Basis Function Neural Network joint with Equilibrium Optimizer Algorithm and Grasshopper Optimization Algorithm to figure out the optimum number of neurons within the hidden layer. Kuala Lumpur’s Klang Valley Mass Rapid Transit transportation network, Malaysia, opted to model the piles’ settlement and earth properties via the proposed hybrid RBF-GOA and RBF-EOA frameworks. By modeling both frameworks, the error index of RMSE for RBF-GOA and HRBF-EOA were gained to 0.6312 and 0.5947, respectively. However, the VAF indicator showed identical results of the rates 96.98 and 97.33, respectively. Overly, the RBF-EOA represented better than RBF-GOA by little efficiency.

A Census of a nation’s people and housing provides statistics about its health, income and social structures at a local level. While the demand for these statistics is unchanged the way they are collected is changing in many nations because of common drivers: cost pressure, web-based collection, decreasing response rates, environmental shocks and the availability of administrative data. Within this context, this paper gives an overview of the evolution of the Census in Israel, Italy, New Zealand, and the United Kingdom and thereby provides an insight of the challenges and solutions of the modern Census.
Integrating surveys with geospatial data through small area estimation to disaggregate SDG indicators: A practical application on SDG Indicator 2.3.1
Authors: Khalil Clara Aida , Candia Stefano Di , Falorsi Piero Demetrio , Gennari Pietro
Published: July 2022

With the adoption of the 2030 Agenda for Sustainable Development, the production of high quality disaggregated estimates of Sustainable Development Goal (SDG) indicators has taken greater significance. In this context, sample surveys are characterized by samples that are either not large enough to guarantee reliable direct estimates for all relevant sub-populations, or that do not cover all possible disaggregation domains. To address these issues, indirect estimation approaches such as small area estimation (SAE) techniques can be adopted. The literature on the use of SAE in official statistics is broad and in continuous progress, yet the number of case studies on SAE methods applied to SDG indicators can still be expanded. After a brief review of the main SAE approaches available along with their principal fields of application, the present paper aims contributing to fill this gap by presenting a case study on SAE to produce disaggregated estimates of SDG Indicator 2.3.1, measuring average labour productivity of small-scale food producers. The discussed empirical exercise is based on a Fay-Herriot area-level SAE model, integrating survey data with area-level auxiliary information retrieved from multiple trustworthy geospatial information systems. Area-level SAE models have the advantage of being easy to implement and do not require accessing survey microdata and unit-level auxiliary information. These characteristics, jointly with the great potentials offered by modern geospatial information systems, offer the possibility of producing good quality disaggregated estimates of SDG indicators at high frequency and granular disaggregation level.
Air Quality and Winter Heating: Some Evidence from China
Authors: Gao Yannan , Sampattavanija San
Published: July 2022

This paper analyzes the effects of central winter heating prevailing in North China on air pollution level. Qin-Mountains and Huai-River borderline that distinguishes the heating and non-heating areas is considered to be a good quasi natural experiment. Regression discontinuity design as well as relevant robustness checks and placebo tests are combined to verify the effects. Distinctions of the effects regarding different groups of areas located in different latitudes are also taken into consideration. Finally, we find that central winter heating contributes to the growth of all major air pollutants of 17.62% on average between non- and heating seasons considering all important cities in heating areas in north China excluding the effects brought by other natural conditions like weather. As latitude increases, central heating contributes more to air pollution level. In the coldest areas, the contribution to the increase of winter air pollutants can reach more than 60% for PM2.5.

Published: July 2022

Electricity trading occurs under different mechanisms in each country, with auctions being one of these mechanisms. Auctions are widely used to determine their remuneration in the scope of clean energy technologies, such as photovoltaics. Added to the auction process’s bureaucracies and uncertainties, the competing photovoltaic project must keep its technical and economic performance maximized. Given this context, this study aimed to contribute to the competitiveness of photovoltaic plant projects in energy auctions through a performance diagnosis model to identify, measure, and analyze factors in the designing process. For this, a systematic literature review was performed to identify the factors that influence the implementation of a photovoltaic plant project; additionally, the fuzzy Delphi method was applied to examine the factors’ importance. An analytic hierarchy process weighted the factors, and the key performance indicators were developed based on the literature and regulation of the electric energy sector. The model was applied in a centralized photovoltaic energy generation project, which presented a performance index of 41.91%, and the sensitivity analysis and prioritization matrix comprised the post-application study of the model. Our model can help planners improve the competitiveness of photovoltaic projects in auctions by observing underperforming indicators.

This study’s goal is to illustrate future energy scenarios for Thailand in the year 2050: Cloud and Clear scenarios. Cloud depicts a scenario of an economy driven mainly by value-based industrial manufacturing. Security of energy supply is prioritized, with an emphasis on environment concerns and GHG emissions. Energy industry is dominated by incumbent businesses, which play important role in energy transition. Clean energy is gaining more market share, but fossil fuels remain the primary source of energy. Clear reflects the new economy driven by new S-curve businesses. Energy sustainability became first priority for national policy. Diverse options for end-users are available for self-management. New players can be competitor in Thai energy industry. Clean energy became one of the main energy sources. The quantitative results show that owing to the pandemic’s impact, short-term energy demand and GHG emissions decrease dramatically, then rebound and split into two scenarios: uptrend for Cloud and downtrend for Clear. Pathway to sustainable energy is revealed in Clear scenario. Peak energy demand can be reached within 2030. The peak of GHG emissions has already passed and will be approaching to the level of 2DC pathway. Therefore, more actions are required to achieve the ambitious goal of 1.5C.

Authors: Fernandez Manuel , Joseph Robinson , Fernandez Vania Maria
Published: July 2022

There is a great flow of funds among countries, money flowing to more attractive destinations than others. Investors prefer to invest in destinations that offer attractive returns and are relatively less risky.  FDI gives access to capital that would otherwise be not available, and provides much-needed foreign exchange, and therefore helps to adjust some of the macroeconomic imbalances in developing countries.  India is in the growth mode, trying to boost the growth rate, but the resources available are limited; hence India is competing against others to make the investment climate more investor-friendly.  This study aims to find out the status of India as an FDI destination, the factors that attract and hinder the inflow of FDI, and how to capitalize on them.  This study is based on secondary data and covers a period of five years.  The study analysis various determinants of FDI and reveals that India has the potential, decent growth, political stability, organized financial system and acceptable policy that makes it attractive to FDI.
Exploring the Antecedents and Brand Avoidance as the Outcome, of Identity Incongruity
Authors: Mostert Pierre , Naude Tiaan
Published: July 2022

One of the leading causes of brand avoidance relates to the incongruence between consumers’ self-image and brands’ images. While previous researchers made recommendations concerning the antecedents of identity incongruity, their recommendations were based on either speculation or on individual measurement items included in larger (unrelated) constructs. This paper addresses this research gap by establishing the antecedents, and brand avoidance as the outcome, of identity incongruity. The link to the study questionnaire was sent by one of South Africa’s leading cellular service providers by means of SMS messages to their customers, inviting them to participate in the study. Results from 276 fully completed questionnaires show, similar to previous studies, a strong relationship between identity incongruity and brand avoidance. Unlike previous research we established that both inauthenticity and brand image predict identity incongruity, but found no relationships between identity incongruity and negative reference groups, deindividualisation, and family influence. The study accordingly identified the actual antecedents practitioners should focus on when trying to minimise the negative consequences of brand avoidance due to identity incongruity.

A dislexia trata-se de um transtorno específico de aprendizagem que se origina nos sistemas cerebrais responsáveis pelo processamento fonológico, afetando o domínio da linguagem, a capacidade de simbolização, a leitura e a escrita. Até o presente momento, os estudos apontam a dislexia como um transtorno crônico, porém, quando diagnosticada precocemente, podem ser realizadas intervenções multidisciplinares capazes de fornecer melhor desenvolvimento cognitivo, intelectual e, consequentemente, melhorar a qualidade de vida do indivíduo. Com base nesse pressuposto, a questão norteadora deste estudo é: qual é o papel do professor no diagnóstico precoce da dislexia? Diante disso, teve-se como objetivo abordar sobre essa deficiência e apresentar como o professor pode contribuir para o reconhecimento e o diagnóstico precoce da criança disléxica. Para isso, realizou-se uma pesquisa bibliográfica nas bases de dados da BVS e da SCIELO e em revistas científicas de educação, artigos científicos, livros, entre outros, a partir da qual foi possível concluir que, para a superação da dislexia nos estudantes, deve ser realizadas ações que promovam diagnóstico precoce e proporcionem o suporte de profissionais qualificados. Para isso, os profissionais da educação devem ter uma formação adequada, bem como competências e habilidades. Ademais, cabe ao governo, o desenvolvimento de políticas que incentivem e contribuam para o diagnóstico precoce da dislexia e para a formação contínua dos professores.

La dyslexie est un trouble d’apprentissage spécifique qui trouve son origine dans les systèmes cérébraux responsables du traitement phonologique, affectant le domaine du langage, la capacité à symboliser, la lecture et l’écriture. À ce jour, les études désignent la dyslexie comme un trouble chronique, cependant, lorsqu’elle est diagnostiquée tôt, des interventions multidisciplinaires capables d’offrir un meilleur développement cognitif et intellectuel et, par conséquent, d’améliorer la qualité de vie de l’individu peuvent être réalisées. Partant de ce postulat, la question directrice de cette étude est : quel est le rôle de l’enseignant dans le diagnostic précoce de la dyslexie ? L’objectif était donc de combler cette lacune et de présenter comment l’enseignant peut contribuer à la reconnaissance et au diagnostic précoce des enfants dyslexiques. Pour cela, une recherche bibliographique a été effectuée dans les bases de données du Bibliothèque Virtuelle des Sciences de la Santé (BVS) et du SCIELO et dans des revues d’éducation scientifique, des articles scientifiques, des livres, entre autres, à partir desquels il a été possible de conclure que, pour surmonter la dyslexie chez les étudiants, des actions qui favoriser un diagnostic précoce et assurer l’accompagnement de professionnels qualifiés doit être réalisée. Pour cela, les professionnels de l’éducation doivent avoir une formation adéquate, ainsi que des compétences et des capacités. De plus, il appartient au gouvernement de développer des politiques qui encouragent et contribuent au diagnostic précoce de la dyslexie et à la formation continue des enseignants.

Background: Stroke is a leading cause of death and disability in the UK with around 90,000 new stroke patients each year. The NHS England (NHSE) Long Term Plan is committed to saving 150,000 lives from cardiovascular disease over the next 10 years and improving the quality of care available for patients who have a stroke.

Methods: This overview was commissioned by NHSE to summarise what we currently know and don’t know across the breadth of the care pathway. We conducted a series of evidence reviews to inform NHSE and its providers (commissioners, primary and secondary care teams, networks) of what needs to be achieved to deliver world class services equitably across England. Here, we present a concise summary of this work.

Results: Our report summarised the findings of 539 research articles, which we organised into ten sections relating to different stages of the stroke care pathway, from prevention in the community, to acute pre-hospital and hospital care, and on to rehabilitation and longer-term care in the community. Priorities include better prevention (with 90% of stroke attributable to modifiable risk factors), and improving awareness to maximise the chances that people experiencing an ischaemic stroke will reach hospital in time to be eligible for acute treatments. We describe the effects of reorganising hospital care into a smaller number of 'hyperacute' centres, and early supported discharge. In the longer term after stroke, the needs of stroke survivors and their families are not being met, but we found little evidence about what works to improve the situation.

Conclusions: We present in this ‘concise’ version, an overview of the evidence to support the delivery of world class stroke care in England. We conclude with an overview of gaps in the evidence base for each area, set out as research questions to be prioritised and addressed.

Mempelajari statistik parametrik bertujuan untuk menganalisis secara komprehensif pencapaian dan peningkatan kemampuan komunikasi statistis mahasiswa yang memperoleh pembelajaran PAKAR (Proyek, Aktif, Kolaboratif, Analitik, dan Realistis), serta mengkaji pengaruh kemampuan awal statistis terhadap kemampuan komunikasi statistis mahasiswa (KKS). KKS bagi mahasiswa diperlukan proses interaksi dalam  mengkomunikasikan ide-ide statistik dengan sumber informasi yang relevan secara kolaboratif. Terciptanya situasi kolaboratif antara mahasiswa dalam membahas masalah yang bersifat realistis melalui implementasi pembelajaran PAKAR. Pembelajaran PAKAR merupakan model pembelajaran inovatif yang mengarahkan mahasiswa secara kolaboratif untuk aktif menyelesaikan proyek masalah realistis sebagai konteks, melakukan analitik sehingga menghasilkan suatu produk. Menggunakan metode campuran model concurrent embedded, data pencapaian dan peningkatan kemampuan komunikasi statistis mahasiswa dianalisis untuk mengetahui hasil implementasi model pembelajaran PAKAR dalam pengajaran pengantar statistik. Subyek penelitian ini adalah mahasiswa program studi Pendidikan Matematika FKIP Unkhair semester genap tahun akademik 2020/2021 sebanyak 20 mahasiswa yang diterapkan pembelajaran PAKAR. Instrumen pengumpulan data meliputi: tes KAS, pretes dan postes KKS, lembar observasi dan wawancara. Berdasarkan hasil tes KAS mahasiswa dikelompokkan atas kategori: tinggi, sedang, dan rendah dengan capaian rata-rata sebesar 56,75 serta simpangan baku sebesar 17,72 dalam kategori rendah. Hasil penelitian menunjukkan bahwa: (1) KKS mahasiswa sebelum pembelajaran dengan rata-rata sebesar 30,25 dengan SB sebesar 11,86 dan sesudah pembelajaran PAKAR pencapaian KKS dengan rata-rata sebesar 90,25 dengan SB sebesar 10,81 mengalami peningkatan (2) Peningkatan  KKS   mahasiswa setelah pembelajaran sebesar 0,87 dalam kategori tinggi; (3) Mahasiswa dengan KAS rendah mengalami peningkatan kategori sedang, KAS sedang mengalami peningkatan kategori sedang dan tinggi, serta mahasiswa dengan KAS tinggi mencapai peningkatan dalam kategori tinggi; dan  (4) Hasil uji hipotesis dengan statistik wilcoxon diperoleh Z= -3,938 dengan Asyimp Sig (2-tailed) sebesar 0,00 menunjukkan bahwa terdapat perbedaan yang signifikan KKS mahasiswa antara sebelum dan sesudah pembelajaran PAKAR. KAS Mahasiswa berpengaruh secara signifikan terhadap peningkatan KKS Mahasiswa setelah implementasi pembelajaran PAKAR. Hasil ini memberikan kesimpulan bahwa implementasi pembelajran PAKAR secara signifikan dapat meningkatkan kemampuan komunikasi statistis mahasiswa dalam mempelajari materi pengantar statistika. Kata Kunci: Pembelajaran PAKAR, Kemampuan Komunikasi Statistis mahasiswa, dan Kemampuan Awal Statistika
