Among four microencapsulated formulations, BGC-1 with melanin recorded significantly highest mortality of 95.00 per cent at 0h exposure, as time increased, the mortality decreased and HD-1 was on par with BGC-1.
Development of a Multiplication Factor for the Kuz-Ram Model to Match the Fragment Size Obtained from Wipfrag Image Analysis
Authors: Das Rajesh Kumar , Dhekne Prakash Y. , Murmu Sunny
Published: April 2024

The degree to which the rock is fragmented by blasting operations significantly impacts the productivity of the opencast mining operation. Over image analysis-based tools, the Kuz-Ram empirical model is preferred for determining the mean fragment size of a blasted muck pile. The fragmentation analysis results by the Kuz-Ram model are said to report the overestimation of the size of the fragments. On the other hand, while accurate, measuring the mean fragment size by image-based analysis is also time-consuming and expensive. Therefore, in the present research, the fragmentation difference index (Fdi) is introduced as a new multiplication factor to reduce the discrepancy in the results obtained using the Kuz-Ram model and the image-based analysis. The error minimization method of least squares is used to formulate the objective function of Fdi. The proposed equation is tested using data sets that weren't used in the model's development. Statistical indicators viz. the coefficient of determination (R2 ) and Root Mean Square Error (RMSE) have been used to evaluate the model's performance. These are found to be 0.80 and 0.007, respectively. The values obtained by multiplying Fdi by the Kuz-Ram results match those of the Wipfrag study, with an average error of 2.09%. Therefore, the suggested methodology will assist the field engineers in cost-effectively calculating the mean fragment size before blasting utilizing only the findings from the Fdi and Kuz-Ram models.

Authors: Sahadevan Priya , Selvan Chithirai Pon , Bhaumik Amiya , Lakshmikanthan Avinash
Published: April 2024

The 17-4 PH stainless steel possesses distinguished applications due to its inherent properties. Higher surface roughness in Selective Laser Melting (SLM) parts limits their use in a wide range of applications. Higher surface roughness deteriorates the important functional properties (strength, fatigue, corrosion resistance and so on). Therefore, an attempt is being made to reduce the surface roughness during the processing stage itself, rather than the dependency of costly secondary post-processing routes. Taguchi L9 experiments are conducted to analyze the laser power, scan speed and hatch distance influence on the surface roughness of SLM parts. Laser power showed the highest percentage contribution equal to 83.37%, followed by scan speed of 9.92% and hatch distance of 6.71%, respectively. Taguchi method determined optimal conditions (laser power: 270 W, scan speed: 1000 mm/s and hatch distance: 0.08 mm) through Pareto analysis of variance resulted in low values of surface roughness with a value equal to 4.11 µm. The results of the optimal condition can be used by any novice user to obtain better surface quality in SLM parts. Further, the Taguchi method can be applied to optimize any process with limited experimental trials and resources.
CFD Analysis of Gas Turbine Blade Cooling with Staggered Holes
Authors: Veerabhadra S. R. , Madhu B. P.
Published: April 2024

The role of turbine inlet temperature plays a pivotal role in determining overall turbine performance. As the temperature at the turbine inlet increases, it leads to an enhancement in the turbine's average efficiency. Gas turbines operate under extremely elevated temperatures, reaching levels of 1200°C to 1500°C. This extreme heat poses the risk of turbine blade melting and potential failure. Consequently, the need arises for a sophisticated cooling mechanism for the turbine blades. Optimally increasing the inlet temperature of the turbine blades can certainly elevate the turbine's overall efficiency. However, it's important to recognize that this increase in temperature directly impacts the durability of the turbine blades. To address this challenge, various innovative cooling technologies have been devised, including the implementation of distinct blade cooling hole configurations. These methodologies aim to ameliorate blade temperatures and consequently enhance turbine performance.Turbine blades are engineered using superalloys, renowned for their ability to withstand high thermal stress. Advanced software tools are harnessed to assess their performance under extreme temperatures. Computational Fluid Dynamics (CFD) software is commonly employed for analyzing turbine blades. A prevailing approach for blade temperature reduction entails employing diverse cooling systems, often utilizing air as a cooling agent. This directed airflow over the blades significantly curtails their temperatures. In this context, blade design featuring staggered hole layouts is applied, and both STATIC and CFD simulations, grounded in defined boundary conditions, are executed, yielding commensurate outcomes. Comparative analysis demonstrates that staggered hole configurations provide superior temperature distribution uniformity across blade surfaces, effectively reducing peak temperatures in contrast to blade configurations devoid of cooling holes..
Humanoid Motion Control using Auto Resonance Neural Network
Authors: Aparanji V. M. , Patil Sujata N.
Published: April 2024

It has been proven difficult to control robots with many mechanical joints due to a variety of problems, including redundant configurations, non-linear displacement, dynamic user surroundings, etc. Iterative computations have been applied to address inverse kinematic problems of industrial robots with up to six Degrees of Freedom (DoF). With one to three degrees of freedom in each of more than hundred joints used by humans for locomotion, the complexity is unfathomable. Consequently, in humanoid structures, algorithmic and heuristic approaches have failed. Numerous research fields that were earlier thought to be challenging to solve with computers have seen interest piqued by recent advancements in artificial intelligence and machine learning. One such domain is humanoid motion. This paper presents a novel kind of Artificial Neural Network named as Auto Resonance Neural Network (ARN). ARN uses the pull-relax mechanism applied by biological systems to control musculoskeletal motion. A variety of functions can be employed to build the pull-relax model, contingent on variables such as range, necessary coverage, and tunability. When employing ARN for joint control, inverse kinematics or some other kind of repetitive solution is not required. Its application is not influenced by the DoF or joint count. The network can use the learning methods like reinforcement learning or supervised or unsupervised learning.

Authors: Premila Swamy D. , George Dimitrov B. E.
Published: April 2024

Human rights are universal basic rights that give equal rights to all individuals irrespective of caste, creed, religion, language, color, or culture. Human rights include all fundamental rights such as the right to equality, education, work and to lead a life with dignity. Human rights help to resolve conflicts and address grievances and discrimination to create a sustainable society. The objective of the present study is to understand the level of human rights awareness among quarry mining employees particularly from the mining sector. There are very few studies that focused on the mining employees on social aspects. Hence, the study was undertaken to assess the level of understanding and awareness among quarry mining employees in urban Bangalore, Karnataka, India. For the said purpose, a descriptive quantitative study using survey–based method was applied and data was collected through random sampling using survey questionnaires. Statistics and thematic analysis on quantitative data indicate urban employees had a general awareness of the subject, but lacked the essential awareness, particularly in terms of economic, social, and cultural rights.
Environmental Sustainability: Harmonizing Construction Mining Industry Practices with the Implementation of Green Consumption and Sustainable Building Materials in Bangalore, India
Authors: Rajendra P. , Mohanasundaram T.
Published: April 2024

This research delves into the imperative of sustainable building materials, spurred by the ecological fallout from traditionally mined construction methods that inflicted harm on our shared ecosystem. As the 21st century dawned, a heightened consciousness necessitated a paradigm shift toward innovative and sustainable construction approaches, particularly in the dynamic urban landscape of Bangalore, a tier I city. The crux lies in harnessing smart, renewable, and bio-based materials, endowed with the dual prowess of carbon reduction and absorption across their lifecycle. However, the journey towards ecofriendly construction encounters barriers, ranging from limited material understanding to standardization dilemmas, the entanglement of multiple decision-makers, fiscal demands, perceived risks, and the pervasive influence of societal dynamics. Within this maze, we examine the role of green consumption goals as an instrumental variable to overcome these obstacles. Employing a carefully constructed questionnaire, data originates from 289 respondents within the construction sector in Bangalore and judgement sampling technique is used. The data are analysed using chi-square, ANOVA, correlation analysis, multiple regression. The finds showed that 38% agreed that their building material purchase decisions were influenced by social groups, while only 15% believed their decisions were unaffected by social group influence. As per Duncan Multiple Range Tests (DMRT), age plays a role in shaping individuals' perspectives and preferences related to sustainable construction practices. In summation, this exploration vigorously advocates for the expeditious adoption of sustainable construction practices, spotlighting the salience of green consumerism as an indispensable agent of change. The narrative converges on the imperative for a recalibration towards intelligent, sustainable practices a trajectory indispensable for forging an environmentally fortified future.

The existence of education for democracy has positive impact on citizens’ political knowledgeand the identification with the democratic values. In the process of civic education, theuniversities and high schools play an important role. Many scholars argue that the high schoolshave a civic mission to serve a public good or the university is the civic mission itself. To examinedemocratic citizenship among high school and university students we use a dataset composed ofthree surveys (2011/2012, 2013, 2015) of 4800 Hungarian students. We build on the literatureabout the empirical and theoretical framework of democratic citizenship to answer the questionif 25 years after the collapse of communism we can witness the emergence of a new generationof democrats in Hungary? Have young people successfully come to terms with their countries' authoritarian past and developed a commitment to democracy as a system of rule? Are theyready to defend it in the face of challenges? Based on the empirical framework of citizenship wederive a number of significant lessons from the Hungarian case, with important implicationsabout the ability to teach the norms and responsibilities of democratic citizenship in the world’semerging democracies.

Authors: Akman Hami
Published: April 2024

Deyim, en genel ifadelerle gerçek anlamından az ya da çok sıyrılarak mecaz bir anlam kazanmış, en az iki kelimeden oluşan kalıplaşmış söz dizileri olarak tanımlanabilir. Türkçe ilk kullanıldığı dönemlerden itibaren oldukça zengin bir deyim varlığına sahip olmuştur. Bu zenginlik Türkçenin sadece yazı dillerinde değil; aynı zamanda ağızlarında da kendisini göstermektedir. İşte bu ağızlardan birisi de Van ağzı olarak da bilinen Van Küresin ağzıdır. Van Küresin ağzı her ne kadar Türkiye Türkçesi ağzı olarak bilinse de taşıdığı birçok özellik onu daha çok Azerbaycan Türkçesine yaklaştırmaktadır. Azerbaycan Türkçesi, Batı Türkçesinin doğu sahasında yer alan ağızlar topluluğu ve bu sahada gelişen yazı dilidir. 13. yüzyıldan günümüze kadar kullanılan Batı Türkçesi zamanla Osmanlı Türkçesi ve Azerbaycan Türkçesi olarak iki ayrı kola ayrılmıştır. Bundan dolayı Azerbaycan Türkçesine Doğu Oğuzcası, Osmanlı Türkçesineyse Batı Oğuzcası denir. Bu çalışmada Azerbaycan Türkçesi ile Van Küresin ağzında kullanılan ortak deyimler ele alınmıştır. Söz konusu her iki dilde, 113 ortak deyim tespit edilmiştir. Bu deyimlere çeşitli kalıplarda rastlanmaktadır (sıfat tamlaması, edat grubu vs.). Deyimler alfabetik sıra gözetilerek sıralanmıştır. Bunların, Türkiye Türkçesi yazı dilinde kullanılmayanlardan oluşmasına dikkat edilmiştir. Çalışmanın sonunda Van Küresin ağzındaki deyimlerin derlendiği “kaynak kişi”lerin listesine yer verilmiştir.

Published: April 2024

Tüm dünyada olduğu gibi Türkiye’de komplo teorileri konusu giderek popüler bir araştırma alanı haline gelmektedir. Ancak Türkiye’de yapılan çalışmalar, bilhassa toplumsal olaylardan sonra ortaya çıkan komplo teorilerine yeterince önem vermemektedir. Söz konusu gerçeklikten hareketle bu çalışma, 1978 yılında Kahramanmaraş’ta gerçekleşen ve “Maraş katliamı” olarak adlandırılan olayları ele almaktadır. Araştırmanın amacı, komplo söyleminin farklı siyasal kesimlere nasıl nüfuz ettiğini ortaya çıkarmaktır. Bu doğrultuda, 2008 yılından sonraki 89 ayrı TBMM tutanağı, MAXQDA programı kullanılarak içerik analizine tabi tutulmuştur. Analizler sonucunda, Maraş katliamıyla ilgili yapılan konuşmaların kamuoyunda ciddi bir yankı bulduğu ve sıradan insanların bu konudaki görüşlerinin milletvekilleri tarafından şekillendirilebildiği görülmüştür. Maraş olayları için bazen “dış güçler” bazen de “dış güçlerin içerideki işbirlikçileri” şeklinde ifade edilen grupların suçlandığı anlaşılmıştır. Araştırmada sol partilerin, sağ partilere göre Maraş olaylarını daha fazla gündeme getirdiği tespit edilirken; dış güçler söyleminin her iki kanattan da kabul gördüğü bulgulanmıştır. Ayrıca solcu milletvekillerinin olaylardaki sağ görüşlü insanları, sağcı milletvekillerinin de olaylardaki sol görüşlü insanları komplocu olarak nitelendirdiği görülmüştür. Milletvekillerinin ABD, NATO, TSK, MİT, Kontrgerilla, derin devlet, ülkücüler (sağcılar) ve Aleviler (solcular) gibi özneleri komplocu olarak işaret edebildikleri anlaşılmıştır.

Published: April 2024

In 2022, Indonesia began the energy conversion pilot project from Liquefied Petroleum Gas (LPG) stoves to induction stoves in Surakarta. Before the program is scaled up, it is vital to conduct an in-depth analysis of the technology readiness, technology acceptance, and user satisfaction to assess program continuity. This research aims to identify what configuration of aspects of technology readiness, technology acceptance, and satisfaction will produce continuance intention and the necessary conditions of continuance usage intention. This study involved 412 conversion program participants in five districts in Surakarta, Indonesia. Utilizing fuzzy-set qualitative comparative analysis (fsQCA), four solution configurations that lead to high continuance intention and four for low continuance intention were obtained. Generally, nearly all conditions must be maintained at a positive level to produce high continuance intention, especially innovativeness, and satisfaction. The research has theoretical and practical implications, including satisfaction having the greatest impact on configurations and the quality of the conversion program, in which the induction stove and its service program must become the main focus to ensure satisfaction. Clear policies and wider socialization must be conducted to enhance people’s awareness and trust. To boost sustainability and continuity, synergistic cooperation between stakeholders and the creation of a better environment for induction stove implementation must also be established. Future research should conduct a longitudinal study approach to strengthen the analysis of a long-term induction stove conversion program.

The start of the COVID-19 pandemic in early 2020 has caused trouble all over the world. This contagious disease is mostly spread by people, and it spreads much faster than other flu viruses that have been found before. Although vaccines have been discovered and are functional, it will still be the greatest challenge to conquer this disease. To effectively respond to this unprecedented crisis and save human lives from other infectious diseases in the future, it is crucial to better understand how the virus is transmitted from one host to another and how future zones of contagion can be anticipated. Several waves of infection have hit nations worldwide for almost the last four years, and governments have implemented necessary measures to tackle the spread of the virus. However, mathematical modeling has emerged as a powerful tool to inform decision-making, allowing for the prediction of COVID-19’s effects. In this research article, we investigate the impact of COVID-19 in Saudi Arabia using the three most commonly used mathematical models: the classic SIR (Susceptible-Infected-Recovered) model, the extended SEIR (Susceptible-Exposed-Infected-Recovered) model, and the advanced fractional-order models using freely available real recorded data for research. By incorporating actual data from Saudi Arabia and utilizing three simulation techniques, we strive to provide valuable insights into the dynamics of the pandemic and aid in the formulation of effective strategies to control its spread in Saudi Arabia.

Sustainability considerations play a crucial role in informing the modeling and fitting of medical and engineering data, ensuring the development of robust and environmentally conscious solutions. This paper delves into the investigation of a novel continuous distribution, aiming to provide a thorough understanding of its various fundamental mathematical and statistical properties. The analysis encompasses an exploration of survival functions, hazard rate functions, quantile, skewness, kurtosis, moments, mean time to failure, mean time to repair, insurance pricing principles, availability, and mean residual (past) lifetime functions. The proposed model demonstrates versatility in modeling both asymmetric and symmetric data across various kurtosis shapes. It can effectively handle outlier observations and accommodate different shapes of failure rates, including unimodal, bathtub, increasing, or decreasing patterns. This makes the proposed model suitable for modeling data in diverse fields. The maximum likelihood approach is employed to estimate model parameters using complete and upper recorded values. A simulation study is conducted to evaluate the performance of the estimators under different sample sizes for both complete and upper recorded values. To further demonstrate the flexibility and effectiveness of the new model, two datasets from medical and engineering domains are utilized for validation and testing purposes.

Published: April 2024

Sistemas de Geração Distribuída são formados pela conexão de diversos elementos como conversores de energia, inversores, filtros, entre outros, que são projetados individualmente para garantir estabilidade e desempenho. Devido à interação entre os elementos conectados, o sistema pode se tornar instável ou oscilatório. A literatura relaciona esse problema ao comportamento de Carga de Potência Constante de conversores operando em malha fechada. Entretanto, este trabalho demonstra que o problema de instabilidade nesse tipo de sistema pode estar relacionado com incertezas presentes na planta e suas interações. Utilizando um estudo de caso que formado por um filtro de entrada LC conectado em cascata com um conversor Buck com um compensador na tensão de saída e, por meio do critério de Middlebrook, identificouse que o sistema em cascata é instável, e através do Teorema do Elemento Extra mostrou-se que isso é devido a presença de dinâmicas não modeladas. Assim, pelo fato de controladores clássicos do tipo PID não garantirem, em muitos casos, a estabilidade, em sistemas conectados em cascata, este artigo propõe um controlador híbrido robusto PID-MRAC. Nesse controlador, a saída do PID é responsável por manter o adequado desempenho transitório e a ação MRAC é responsável pela robustez em relação às incertezas estruturadas e não estruturadas.

Africa is a huge and diverse continent in terms of land mass, natural resources, peoples, culture and level of economic development, with each region and country showing considerable variations and further diversity. The economic history of many countries in Africa and the continent at large during the last century has been one of negative results, false starts and even decline. The continent often leads the rest of the world in nearly all the wrong and negative statistics – high poverty incidence, low human development index, corruption with impunity, prevalence and persistence of some of the most deadly communicable diseases such as malaria and HIV/AIDS, high infant and maternal mortality, recurrent food and nutrition insecurity, high frequency of political strife and instability, and the list goes on and on.

As we come to the end of 2014, there is a lot to be grateful for. As AJFAND, we have managed to sustain the journal, and continued to give visibility to the contributors and to inform our readers about Africa's agricultural, food security, and nutrition research and activities. We owe all this to our authors, without whose manuscripts we would not have anything to publish. Sometimes we take longer than is expected, not intentionally; and sometimes we push our authors to hasten in making their corrections. Then there are those whose manuscripts we must reject, but only where the design is wrong or the review process does not pass the manuscript. In January next year, we shall share data on the rejection rates in the past few years. We then have our reviewers. Because our journal is multidisciplinary, our reviewer base is diverse and fairly robust. The dedication of these reviewers is amazing. We have kept quite a number right from inception in 2000/2001; we keep adding to the list with mostly those who volunteer and others we identify that have excellent writing skills through their contribution of manuscripts to the journal. We value both our peer and technical reviewers. There are many reviewers I have to yet meet. Then we have our technical and financial supporters, who help us to sustain the journal. You are most valued and we look forward to continued collaboration. THANK YOU SO MUCH. We have our more than 10,000 readers, just through the AJFAND website alone.
A aplicação da metodologia feminista de Alda Facio Montejo como chave de compreensão da manifestação do sexismo em entidades coletivas da educação básica
Authors: Martins Thaís Rodrigues , Reis Stella Mendes de Castro
Published: April 2024

O objetivo do presente estudo é analisar as diferentes manifestações do sexismo no bojo das relações coletivas docentes e no âmbito de suas entidades representativas, questionando os papéis de gênero estabelecidos com base nas reflexões propostas por Alda Facio Montejo na obra “Cuando el género suena câmbios trae” (1992). Para tanto, o procedimento metodológico empregado foi a revisão bibliográfica com uma abordagem qualitativa, utilizando como marco teórico a obra mencionada. Partindo da problematização da concepção de docência como atividade vocacional feminina, exploramos os seis passos desenvolvidos por Montejo em sua metodologia feminista para aplicar as lentes de gênero nas relações sindicais docentes e verificar de que maneira as diferentes formas de sexismo se apresentam, além dos seus impactos. Apontamos, ainda, os avanços constatados a partir de pesquisas recentes e as proposições de superação dessas opressões por meio da conscientização dos sujeitos envolvidos e de um processo cíclico e coletivo.
Os usos do conceito de branquitude para uma educação antirracista no Brasil
Authors: Gomes Thais Bonato , Soares Francisco Muenzer
Published: April 2024

O presente artigo tem como intuito defender a relevância do entendimento sobre branquitude como categoria analítica para a efetivação de uma educação antirracista no Brasil. A partir do referencial teórico de(s)colonial, buscamos demonstrar a importância de deslocar as problematizações raciais das vítimas do racismo para as pessoas que usufruem dos privilégios oriundos das hierarquias raciais assim como expor a pretensa superioridade, a qual a universalização colonial pressupõe em seu projeto de racialização dos corpos. Autores e autoras de destaque no campo dos estudos críticos da branquitude, como Cida Bento, Lia Schucman e Lourenço Cardoso, são discutidos. Por fim, analisamos que são bem-vindas abordagens pedagógicas que se proponham a inserir esse debate, principalmente se houver uma perspectiva estrutural que não essencialize as identidades. De tal modo, é possível confrontar as desigualdades entranhadas na sociedade brasileira, rejeitando discursos rasos sobre “diversidade” e, sobretudo, negando a branquitude como norma.
Pomiędzy protorasizmem szlacheckim a rasizmem naukowym. Studium porównawcze praktyk urasawiania innych na przykładzie polskich chłopów pańszczyźnianych i Afroamerykanów
Authors: Taradejna Paweł
Published: April 2024

Celem artykułu jest dokonanie studium porównawczego zjawisk protorasizmu szlacheckiego i nowożytnego rasizmu naukowego oraz ujęcia ich, zgodnie z funkcjonującą praktyką akademicką, w kategorii faktów społeczno-kulturowych. Autor zarysowuje charakterystykę zjawisk: polskiego protorasizmu szlacheckiego i medykalizacji pojęcia ludzkiej rasy w Stanach Zjednoczonych na przełomie XIX i XX wieku, zaprzęganej w proces wtórnego uprzedmiatawiania nie-białej ludności. Wskazuje na pewne elementy wspólne praktyk urasawiania Innych zarówno w szlacheckiej Polsce, jak i oddalonej w czasie Ameryce. W tym kontekście rozpatruje rasizm jako kategorię analityczną będącą narzędziem Foucaultowskiej władzy dyskursywnej, podkreślając jej klasowy i dystynkcyjny charakter. Zwraca uwagę na przemiany, które dokonywały się w rozumieniu pojęcia rasy wraz z postępującym rozwojem oświeceniowego europejskiego ideału naukowości. Wskazuje na cechy i figury powszechnie utożsamiane z Innymi. Ich podobieństwo tłumaczy wspólnym rdzeniem, wywodzącym się ze wczesnego europejskiego etnocentryzmu.
E-Moodle Flipbook: Deconstructing local wisdom-based social studies learning media innovations, to improve students' critical thinking skills
Authors: Hasni  , Nana Supriatna  , Sapriya  , Murdiyah Winarti
Published: April 2024

The key motivation behind this research is the lack of Moodle flipbooks as an innovative tool for teachers to use and the lack of Moodle flipbooks as a local knowledge-based social studies learning medium to enhance students' critical thinking abilities. This study aims to determine the effectiveness of using Moodle flipbooks based on local wisdom in improving students' critical thinking skills, in the material of community life during the pre-literacy period. The research method is a quasi-experiment with the design of the matching-only pretest-postest control group design.  This research was conducted at SMP Negeri 2 Makassar, Indonesia with a research sample of 70 students, consisting of class VII A students 35 students (experiment class) and class VII B 35 students (control class). Effectiveness is measured based on n-gain test results analyzed with t-tests developed by Hake. The results of the study found that the use of Moodle flipbooks as an innovation in social studies learning media based on local wisdom was quite effective for improving students' critical thinking skills, as evidenced by the n-gain of the experiment class higher and significantly different from the control class.

Az egészségbiztosítások árazási módszerei, folyamatai és kihívásai
Authors: Németh Péter
Published: April 2024

A tanulmány célja, hogy bevezesse az olvasót a legfontosabb egészségbiztosítások világába. A termékek bemutatása mellett az árazáson és az ehhez felhasználható statisztikai adatokon lesz a hangsúly. Az egészségügy romló helyzete és az orvoshiány miatt felértékelődnek a magán-egészségügyi intézmények, amelyek finanszírozására kiváló eszköz a biztosítás. A bemutatott modellek esetében a számításokat az aktuáriusi kommutációs számok segítségével végeztem el. Szó lesz a Markov-modellekről és azok felhasználási lehetőségeiről is. A téma kapcsán bizonyos modellek esetében fontos megemlíteni a nélkülözhetetlen statisztikai adatok hiányát, ami megnehezíti az ilyen jellegű kutatásokat. Annak érdekében, hogy az olvasó képet kapjon a különböző termékek díjáról, ahol vannak jó minőségű elérhető adatok, ott minden termék esetén egy nettódíj-kalkuláció szerepel, a többinél pedig szakértői becslés alapján határoztam meg a díjat, amelynél a becslés alapja a piaci biztosítók termékeinek a bruttó díja. Az eredményeket tekintve elmondható, hogy egy komplex, mindenre kiterjedő biztosítás a háztartások többsége számára hatalmas költséget jelent.

„Querschnittsthemen“?
Authors: Saß Marcell
Published: April 2024

Lehramtsstudierende benötigen fachübergreifende Kompetenzen im Sinne von Future Skills, um große gesellschaftliche Herausforderungen in Schulen zu bearbeiten. Für eine nachhaltige Lehrkräftebildung ist daher die Implementierung von sog. Querschnitts- bzw. Transversalthemen (Nachhaltigkeit, Digitalität, Diversität u.v.m.) gesellschaftlich notwendig und zunehmend gesetzlich geregelt (z.B. im HLbG, 2022). Der vorliegende Beitrag thematisiert grundsätzlich die Genese und Geltung von Querschnittsthemen in der Lehrkräftebildung anhand der Impulse des Marburger Projekt ProPraxis und bezieht diese sodann auch auf die Zukunft der Religionslehrkräftebildung.
Online career construction for a trauma survivor with career choice ambivalence
Authors: Maree J.G
Published: April 2024

This article reports on the online administration of career construction counselling for a trauma survivor who sought help in resolving her career-choice ambivalence (uncertainty). The participant was purposively selected from a group of people attending a workshop on career construction counselling. An intrinsic, descriptive, exploratory intervention case study based on career construction counselling (involving administering the Career Construction Interview (CCI) to elicit the participant’s micro-narratives qualitatively) was used to generate data and adapted thematic data analysis incorporating the analytic style proposed by Savickas was used to analyse the data reflexively. The intervention shed light on the participant’s conscious knowledge about herself and on her subconsciously regulated views on her preferred future career choices. The findings confirmed the value of career construction counselling in promoting the participant’s psychological self as an autobiographical author especially. They also underlined the importance of timely intervention for trauma survivors in pre-empting the occurrence of unmastered developmental tasks and repetition of trauma. Future research should involve diverse participants in individual as well as group contexts. Equally important is contextualising the intervention discussed here to meet the distinctive diversity needs of participants in individual and group contexts.
The reshaping of curriculum transformation to address the 21st-century skill sets and employment prospects during the Fourth Industrial Revolution era: A case of the South Africa TVET colleges
Authors: Kana N , Letaba P
Published: April 2024

This research explores the employability of Technical and Vocational Education and Training (TVET) college graduates in the Fourth Industrial Revolution (4IR) era in South Africa. It examines the role of TVET lecturers in providing skills that are relevant to the contemporary period. The study uses qualitative research inspired by the interpretivist approach, and a purposive sampling strategy to get the perspectives of TVET lecturers and employers. It was observed that TVET lecturers play a minimal role in the development of the curriculum due to a rigid top-down approach from the Ministry of Higher Education. Companies are forming partnerships with TVET colleges by offering places for in-service training, practicals and internships. The study reveals that South African businesses have adopted 4IR-related technologies, requiring a skilled TVET force that is ready for these transformations. The findings highlight the need for regular curriculum transformation and the importance of TVET education in producing artisans, technologists and technicians that are vital for the South African economy on an ongoing basis.
