Impact of Liner Shipping Connectivity on Container Traffic in Turkish Ports
Authors: Atacan Can , Kayıran Burhan , Açık Abdullah
Published: January 2023

Demand for the transport sector is a derived demand; however, the transport sector is not only affected by the demand for the goods transported, but can also influence demand for itself by providing more transport facilities, which can affect trade by generating more options for foreign trade stakeholders. Accordingly, we have examined the effect of the Liner Shipping Connectivity Index (LSCI) variable, which is an indicator of countries' liner transportation connectivity, on Turkey's export and import container traffic, by using regression analysis. We have enriched our model by adding the real exchange rate variable, which is the most important factor affecting foreign trade. Our results show that a 1% increase in the country's LSCI increases export and import container traffic by approximately 1%. This result shows that not only exchange rate and production policies, but also transportation policies, are critical in improving foreign trade of the country. The development of transportation facilities can both reduce transport costs and shorten the delivery time, thereby supporting Turkey's policies to become a production centre.
Scrutinizing the Manifestation of Relational Norms: A Study of Terminal Operating Company-Liner Shipping Agency Relations
Authors: Bilge Sağlam Bayram , Karataş Çetin Çimen
Published: January 2023

Port relations with port users are essential for overall supply chain functioning, as the roles assigned to ports grow every day. While port supply chain transactions are generally conducted using contractual governance mechanisms, ports need to develop relational norms to keep their relations with port users at a high level, helping the ports realize their desired performance levels. This study aims to show the role of relational norms through the classification of domains they are manifested in. The goal of the classification is to unravel the specific domain of each norm in terminal operating company-liner shipping agency relations by exploring their occurrence and functioning. The data were gathered through interviews with professionals from terminal operating companies in Aliaga and liner shipping agencies that use at least one of these terminals. Study results show that the norms “flexibility” and “solidarity” are manifested as the financial and operational parts of the relation, while the norm “information sharing” is closely related to the effective use of information exchange platforms and the quality of exchanged information.  The findings show how relational norms can add value to relationship performance in contract-based port supply chain relations.

Authors: Kamis Amir Syawal , Ahmad Fuad Ahmad Faizal , Anwar Aimie Qamarina
Published: January 2023

This study aims to review the methods that can be used to identify the wheel-over point for a ship’s effective course alteration. Using the systematic literature-review technique with reference to the PRISMA model, this study was able to collate the methods identified through a thematic analysis that was appropriate to the technique’s fundamental principle. As a result, four themes were identified: ROT Turns, Fixed Radius Turns, RADAR Turns, and Fixed Rudder Angle Turns. It was also discovered that the techniques applied by mariners varied according to the navigation region. The navigation regions can be categorised into three areas, i.e. ocean navigation, coastal navigation, and harbour and confined-water navigation. The methods found in this research can be used aboard ship to aid the navigators in making more efficient course alterations for the purpose of enhancing the safety of navigation.

Authors: Ilčev Dimov Stojče
Published: January 2023

This paper introduces implementation of the new project known as African Satellite Augmentation System (ASAS) for Africa and Middle East, designed by the CNS Systems Company and its research group supported by partners. The ASAS project as Regional Satellite Augmentation Systems (RSAS) will provide service for maritime, land (road and rail), and aeronautical applications. Thus, with existing and other newly designed RSAS networks, it will be integrated in Global Satellite Augmentation System (GSAS) with new Satellite Communication, Navigation and Surveillance (CNS) for improved Ship Traffic Control (STC) and Ship Traffic Management (STM). This System also enhances safety and emergency systems, transport security and control of ocean shipping freight, logistics and the security of the crew and passengers onboard ships and fishing vessels as well. The current CNS infrastructures of the first generation of Global Navigation Satellite System (GNSS-1) applications are represented by old fundamental solutions for Position, Velocity, and Time (PVT) of the satellite navigation and determination systems, such as the US GPS and Russian (former USSR) GLONASS military requirements, respectively. The establishment of Space, Ground, and User segment, including Local Satellite Augmentation System (LSAS), are discussed as a new basic infrastructures for maritime and other mobile applications, which will be integrated with RSAS in the future GSAS network.
Analysis of the European Union COVID-19-Related State Aid Rules and Their Application in the Croatian Maritime Sector
Authors: Bulum Božena
Published: January 2023

The paper presents the possibilities that Member States have under Temporary Framework for State aid measures to support the economy in the current COVID-19 outbreak to subsidise undertakings having liquidity problems or suffering damage because of the COVID-19 outbreak. Under the European Union Law, State aids are forbidden. However, some exceptions from that general rule are expressly provided for by the Treaty on the Functioning of the European Union. The Member States mostly used Article 107, paragraphs (2) and (3) of the Treaty as a legal basis for subsidising their economies in the COVID-19 pandemic, which has been qualified as an exceptional occurrence causing a serious disturbance in the economies of Member States. In the decisions authorising the State aid granted due to the COVID-19 crisis, the European Commission referred to its previous decision-making practice and the case-law of the Court of Justice of the European Union. Finally, the paper analyses the national State aid scheme that the Republic of Croatia adopted to support undertakings performing economic activities in the maritime and related sectors, based on the relevant EU regulations.

Authors: Miyusov Mykhaylo V. , Nikolaieva Liudmyla L. , Smolets Vitaliy V.
Published: January 2023

The lack of human resources in the maritime labour market provokes a rapid promotion of maritime professionals, which in turn reduces the time to acquire required skills. More than 40 % of all cases of human errors on vessels were caused by an insufficient level of training, practical skills and education of human resources. This paper represents an overview of a research evaluating a virtual reality (VR) practical training course. Main aim of this course is to evaluate the effectiveness of immersive learning implementation into maritime education and training and establish VR metrics. This research on VR training represents a metric-based view of VR experiments and research. There was developed a VR training case which is called ‘Wall wash test procedure on chemical tanker’ as an enhanced synthetic virtual reality environment for performing tasks and tests for the evaluation. A pedagogical experiment was conducted while training 115 navigator cadets at National University Odessa Maritime Academy (NU OMA). Its main goal was to establish the dynamics of changes in indicators to improve the quality of education through the use of VR. Tracking of this dynamic was done using the theory of statistics. VR experiment quantitative and qualitative analyses have confirmed support of the cognitive effort and improvement of memorization of students. Use of VR in the study of navigator cadets significantly increases the overall performance of their learning process. The effect of the user’s presence in the virtual space and the effect of depersonalization and modification of the user’s self-awareness in virtual reality gives unambiguously positive results. Thanks to specialized VR models, navigator cadets can increase the quality of mastering new knowledge by almost 26 %. Due to such improvement of professional training, it is possible to increase the general level of safety during conducting specialized vessel technological operations. The obtained researches results are very important in terms of improving the overall safety on marine vessels.
Socioeconomic Characteristics and Perspectives on Cargo Handling: A Study of Tin Can Island Port, Apapa, Nigeria
Authors: Oluwakoya Adeniyi , Ogundipe Seun
Published: January 2023

This research examines the socioeconomic and cargo handling characteristics of the Tin Can Island Port in Nigeria.  The rise in global trade agreements has led to a cargo handling crisis in Nigeria.  However, the perspectives of the socioeconomic characteristic have not yet been studied. The sampling method used was simple random sampling, with 100 questionnaires given to all the employees and consumers who use the terminal.  However, the study was based on 93 respondents who completed the survey satisfactorily.  In addition, it includes in-depth interviews with some of the port-terminal employees, a few customers, and neighborhood residents on the use of intelligent port systems.  The data instruments' validity and reliability were checked with a Cronbach alpha reliability test of 0.80-0.89 and found to be accurate for all the parameters.  The information was analyzed using descriptive, qualitative, and chi-square statistical methods.  The study found that socioeconomic factors, especially the age of the cargo handling staff, impacted the port's capability.  The level of port automation and the adoption of intelligent port systems are still relatively low, though remarkable since the reforms.  The research shows a significant relationship between the perception of cargo traffic level and change in the cargo handling procedure at Tin Can Island Port.  In addition, it reveals a substantial connection between policy adoption and cargo handling improvement at the port.
Impending Effects of Shipping Phenomenal Undertaking on Shipboard Safety: Sleep Problem as Moderator
Authors: Man Azhar , Zainuddin Wan Abdullah W Muhamad
Published: January 2023

Throughout maritime history, disasters have led to the loss of many human lives, environmental pollution, and property loss. The historic sinking of the iconic Titanic on 14 April 1912 had prompted massive change and enhancement in shipping regulations. Nonetheless, the shipping industry still encounters similar incidents. This study aims at empirically examining the effects of Work-Family Conflict (WFC), Quality Regulatory Activity (QRA), Ship Owner Efficiency Demand (SOED), and Sleep Problem (SP) towards Shipboard Safety (SS). A theoretical model was adopted to measure the relationship between the variables considered. A structured self-administrated questionnaire was developed and disseminated to seafarers via the Human Resources department of various shipping companies and social media outlets. Quantitative analysis and a five-point Likert scale were utilized to quantify the respondents’ feedback. A total of 314 useable seafarers' responses from 12 countries provided intrinsic value from the perspectives of cultural and race adaptation towards safety behaviour. The data were subjected to the reliability, explanatory factor, normality, correlation, and regression analysis, to determine the validity, relationship, strength, and effects of the constructs in the research objectives. The research attested the conceptualised model and pedagogic QRA and SOED positive effects on shipboard safety, whilst WFC and the moderating tool - SP, found not moderated WFC, neither influencing shipboard safety. This research has proposed a new phenomenon that prompts shipboard safety, predicted to contribute towards the industry from different views of safety-related elements, and provide valuable insight for shipping companies, authorities, and maritime organisations.
Favouritism in Ship Management: A Scale Development and Validation
Authors: Muslu Aziz
Published: January 2023

The most important determinant of quality and safety in ship management is human resources. Personnel turnover rate, job satisfaction level of seafarers, organizational commitment, high level and individual well-being of the employees, have an important role in ensuring quality and safety. In many studies, it may be seen in the results of research that favouritism increases job stress and personnel turnover rate, while decreasing job satisfaction, organizational commitment, motivation, and teamwork. Favouritism has a negative impact on safety and quality management of ships. Based on this important consideration, in this study seafarers' perceptions have been measured, with an aim at developing a valid and reliable favouritism scale. The scale questions, prepared on the basis of semi-structured interviews and favouritism studies, have been applied to 252 different seafarers. As a result of the factor analyses conducted in SPSS 23, a 22-item favouritism scale, consisting of three factors related to demographic and personal characteristics, social rights and opportunities and operational processes, has been developed. The reliability and validity studies of the scale have been conducted, and it has been observed that the scale has high reliability.
Tribute to Kurt Opitz (1931-2021) - German Contributor to Maritime English
Authors: Čulić-Viskota Adelija , Rummel Hans
Published: January 2023

This paper aims at providing an insight into the work of late Professor Emeritus Kurt Opitz, German lexicographer, and applied linguist as an ESP practitioner with special regard to Maritime English. A list of Opitz’s contributions to both the above-mentioned linguistic branches has been compiled and attached to this paper. His work has been considered as contributing to identifying and providing insight into some crucial issues in lexicography, especially the production of a learner’s dictionary. Familiarity with these issues was enabled by Opitz’s performing the role of Maritime English lecturer. In addition, the activity in the field of maritime education and training encouraged him to envisage and organize the teacher training activities within a national association, but with a view of openness to the worldwide Maritime English teaching community, which resulted in the foundation of G.A.M.E. (Gesellschaft für Ausbildung in Maritimem Englisch = German Association for Maritime English / Association for Maritime English). The paper presents Kurt Opitz along the line of his distinctive personal and professional development, not only as a linguist with particular fascination for lexicography, but also as an applied linguist with a great enthusiasm for the promotion of constantly updated Maritime English and its teaching methodology. Other, not so widely known facets of Opitz’s interests, e.g. his polyglot and literary profiles, have been discovered by the authors during this research and are brought here before our readers.
Implementation of Aggregated Response Plan to Effectively Protect Crew Health and Safety and Prevent Spread of Covid-19 Pandemic Aboard Ships
Authors: Boviatsis Michael
Published: January 2023

The global outbreak of Covid-19 has had a severe impact affecting all maritime sectors. It caused a significant worldwide health and economic crisis with a wide-ranging impact on maritime transport and trade. During this period, access to essential goods and medical items was ensured mainly by the ability of the marine supply chain to adapt by developing systems and processes quickly. Thus, regulations and instructions were imposed in response to the pandemic to monitor and counter the spread and the ancillary effects. This paper aims to assess and codify all those maritime regulations and instructions hastily created to protect the crew's health and safety and prevent the spread of Covid-19 aboard ships. Initially, all relevant rules and countermeasures to crew health and safety are explored and evaluated under the exploratory research coupled with the analysis of the relevant regulatory framework. Then, methods and processes are being created and proposed to offer a composed reaction plan to each case where the effects and consequences of the pandemic may occur. The relevant regulations are the primary source of data and similar studies conducted presently, whose outcomes are used to create and justify the recommended processes and the steps that should be followed based on the special conditions of individual cases. The paper concludes that implementing standard processes and procedures, such as those provided by the analysis, will enhance the speed and the effectiveness of handling the pandemic. It is also concluded that proactive measures coupled with fast and efficient responses are critical for developing effective procedures.

Authors: Aydin Onder , Celik Metin , Bicen Samet , Bayer Dincer
Published: January 2023

This study proposes a methodology to deeply analyze the multi-source inspection/audit findings gathered from a ship fleet to promote and implement proactive measures systematically. In addition to the ship audit reports of Company-A operating 16 bulk carriers in the Black Sea and the Mediterranean, the multi-source inspection database also consists of benchmarking datasets of different fleets. The Ship Smart Audit System (SSAS), including data collection, causation, analysis and prioritization, and implementation phases, is developed to strengthen the maritime regulatory compliance. Particularly, the Marine Systematic Cause Analysis Technique (M-SCAT), Cognitive Mapping (CM), and Pareto analysis are integrated into methodological background of the study. The SSAS is demonstrated with 5,000 findings from the benchmarking dataset and, subsequently, over 1,900 findings from the Company-A. Then, cause priorities, root cause trends, preventive actions, and audit item preferences are identified as an interconnected process of the ship management company. Consequently, the study encourages maritime executives to increase the effectiveness of pre-inspection and internal audit implementations.

Authors: Jeevan Jagan , Maskey Reenu , Chen Shu-Ling , Sharma Rajan , Mohd Zaideen Izyan Munirah
Published: January 2023

Malaysia is a coastal country surrounded by sea, while Nepal is a landlocked country with no direct access to the ocean. This paper investigates the challenges faced by dry ports in Malaysia and Nepal and looks into issues concerning the connection of seaports and dry ports both intra-regionally, i.e. within Malaysia, and inter-regionally, i.e. outside of Nepal. The structure of dry port operating systems in these two areas is visibly different. Hence, the relationships between the major nodes in these different geographical regions need to be examined. Face-to-face and telephone interviews with dry port operators, legislative personnel, and public policy stakeholders from both countries were conducted to establish the impediments to dry port operations. Interview session transcripts have been analyzed using grounded theory. This tool is suitable for this paper due to its capacity to identify categories and concepts within the text linked together to form theoretical models. Secondary data have been used to support the primary data collected, to enhance the range and reliability of the findings. The findings indicate challenges such as inadequate connectivity capacity, inefficient border transactions, seaport-dry port integration issues, inefficient economic corridors, insufficient legislative framework for policy and regulation development, and environmental issues faced by the two countries. These challenges have a negative impact on the possibility of dry ports in Malaysia to take full advantage of their potential. Meanwhile, in Nepal, such challenges limit dry port operations since dry ports are the main gateway for the nation’s international trade. This paper recommends strategies for overcoming these challenges and improving the quality of dry port operations, focusing on the provision of sophisticated and modern logistics services to stakeholders in the different geographic landscapes.

Published: January 2023

Friction stir processing (FSP) is a solid-state and effective process for surface modification of aluminium alloys. In this study the AA5052 alloy, widely used in marine applications, has been subjected to FSP. The FSP trials have been carried out by altering the FSP process parameters (tool rotation speed, tool traverse speed, and shoulder diameter). The friction stir processed specimens have been characterised / tested for microstructure, microhardness, sliding wear, immersion corrosion, and electrochemical corrosion. The hybrid polynomial – radial basis function-based models have been developed to determine the relationship between the process parameters and the evaluated properties. Furthermore, the optimum parameters for obtaining high hardness, wear resistance, and corrosion resistance have been determined. Microstructure evaluation in the friction stir processed specimens has shown refinement and uniform dispersion of β particles throughout the α-Al matrix. The results show that the improvement in properties is a result of the homogeneous dispersion of secondary β phase particles in the matrix. Friction stir processing of AA5052 alloy has  improved hardness by ~14.5%, wear resistance by ~83%, and corrosion resistance ~87%. The optimum process window for friction stir processing of AA5052 alloy is tool rotation speed between 500 rpm and 900 rpm, tool traverse speed between 10 mm/min and 30 mm/min, and tool shoulder diameter of 18 mm and 21 mm.

Published: January 2023

It can be said that there is a day in the entire world when a company is not established or ceases its activity. Among these companies, credit institutions also have their place. The requirements that must be met when establishing banks and other credit institutions are as a rule, more rigorous than when establishing other business entities. Therefore, credit institutions are established less frequently. It can also be noted that they disappear from economic life less frequently. The emergence, and especially the disappearance of a credit institution does not go unnoticed. The same is true for other companies, unless they belong to a group of large and globally known companies. The aim of this paper is to analyse the trends in the establishment and failure of credit institutions in the Republic of Croatia in the period from 1991 to 2020. The research was conducted by studying domestic and foreign scientific and other relevant literature.

Korzyści środowiskowe i zdrowotne jako efekt realizacji polityki klimatycznej i rozwoju energetyki rozproszonej
Authors: Adamiec Ewa , Jarosz-Krzemińska Elżbieta
Published: January 2023

Zanieczyszczenie powietrza uważane jest za znaczący czynnik ryzyka środowiskowego odpowiedzialny za przedwczesne zgony na całym świecie. Szacuje się, że każdego roku w Europie występuje ich około 400 tys. i są one związane z chorobami układu oddechowego, a także chorobami nowotworowymi, w szczególności z rakiem płuc. Zanieczyszczenie atmosfery przyczynia się do stanów zapalnych, a po długotrwałym oddziaływaniu powoduje uszkodzenia DNA. Ostatnie badania potwierdziły również, że pojawiające się symptomy depresji, chorób Parkinsona i Alzheimera są związane z zanieczyszczeniem powietrza. Stale pogarszająca się jakość powietrza przy równoczesnym występowaniu wysokich temperatur związanych ze zmianami klimatycznymi znacznie zwiększa częstotliwość zaostrzających się objawów chorobowych, hospitalizacji i zgonów. Rozwiązanie problemu jakości powietrza i pogłębiających się zmian klimatycznych jest obecnie jednym z priorytetowych celów polityki Unii Europejskiej. Jej działania skupiają się na redukcji emisji zanieczyszczeń, w tym gazów cieplarnianych, wprowadzaniu rozproszonych źródeł energii oraz oszczędności energii. Odnawialne źródła energii stały się narzędziem służącym ochronie środowiska. Skutki środowiskowe można przełożyć bezpośrednio na korzyści finansowe, w rozumieniu zysków z uniknięcia kosztów zdrowotnych spowodowanych złą jakością środowiska. Należy również zauważyć korzyści społeczno-ekonomiczne związane z nowymi lokalnymi miejscami pracy, które tworzy m.in. energetyka rozproszona.
Magazyny energii – inteligentne zarządzanie energią na przykładzie Automatic System Engineering
Authors: Marat Arkadiusz
Published: January 2023

W dobie wzrastających cen i rosnącego zapotrzebowania na energię elektryczną inteligentne zarządzanie energią stało się dla przedsiębiorstw kwestią kluczową. Transformacja energetyczna, która dokonuje się na terenie Polski, nie może zostać przeprowadzona bez udziału magazynów energii. Zarządzanie energią przynosi korzyści finansowe, ale również przyczynia się do zmniejszenia śladu węglowego przedsiębiorstw. Świadoma tego jest Grupa Technologiczna Automatic System Engineering, która do swojej struktury zużycia energii elektrycznej wprowadziła energię z odnawialnych źródeł i z magazynu. Oczekiwanym efektem tego rozwiązania jest zmniejszenie zużycia paliw kopalnych oraz emisji CO2 do atmosfery, optymalizacja kosztów zakupu energii elektrycznej, a także poprawa jakości zasilania. Magazyn zlokalizowany na kampusie Grupy Technologicznej ASE jest połączony z instalacją fotowoltaiczną, a w przyszłości planowane jest dodanie turbiny wiatrowej. Magazyn energii spełnia pokładane w nim oczekiwania, a w przyszłości może stać się elementem infrastruktury krytycznej polskich przedsiębiorstw.

Topological materials have attracted much attention due to their novel physical properties. These materials can not only serve as a platform for studying the fundamental physics, but also demonstrate a significant potential application in electronics, and they are studied usually in two ways. One is to constantly explore new experimental phenomena and physical problems in existing topological materials, and the other is to predict and discover new topological material systems and carry out synthesis. In a word, high-quality crystals are very important for studying quantum oscillations, angle resolved photoemission spectra or scanning tunneling microscopy. In this work, the classifications and developments of topological materials, including topological insulators, topological semimetals, and magnetic topological materials, are introduced. As usually employed growth methods in growing topological materials, flux and vapour transport methods are introduced in detail. Other growth methods, such as Bridgman, float-zone, vapour deposition and molecular beam epitaxy methods, are also briefly mentioned. Then the details about the crystal growth of some typical topological materials, including topological insulators/semimetals, high Chern number chiral topological semimetals and magnetic topological materials, are elaborated. Meanwhile, the identification of crystal quality is also briefly introduced, including the analysis of crystal composition and structure, which are greatly important.

The flipped classroom model is an innovative and increasingly popular pedagogical approach in higher education. However, despite its increasing popularity, few studies have elaborated on specific strategies to implement a flipped classroom model. This study has as its purpose to investigate the effect of an extended flipped classroom model for fully online learning and its interaction with working memory capacity on students’ reading comprehension by means of a quasi-experimental study with a 2 x 2 factorial design in which a total of one hundred and twelve students participated for nine weeks. The two-way analysis of variance revealed that students’ reading comprehension ability increased significantly in the extended flipped classroom model compared to that of students in the original flipped classroom. Students with a high WMC also largely outperformed their counterparts with a low WMC in reading comprehension, an interaction effect being thus identified between the instructional model and WMC as well. This paper concluded with a call to implement an extended flipped classroom model in reading courses and to undertake more specific types of research into the effectiveness of this model across different settings and language skills.
How to Embed SRL in Online Learning Settings? Design Through Learning Analytics and Personalized Learning Design in Moodle
Authors: Molins Laia Lluch , García Elena Cano
Published: January 2023

One of the main generic competencies in Higher Education is “Learning to Learn”. The key component of this competence is the capacity for self-regulated learning (SRL). For this competence to be developed, peer feedback seems useful because it fosters evaluative judgement. Following the principles of peer feedback processes, an online peer feedback proposal was created in the context of complex tasks in several degree courses (n = 448 students) at the University of Barcelona. A specific didactic sequence supported by digital technologies through Moodle was designed and validated after a deep analysis of the theoretical underpinnings of SRL models. A peer review proposal was ratified by the students, who pointed out the benefits of both receiving and, especially, giving feedback. The integration of Moodle tools with external tools such as Personalized Learning Design was highly valued by reviewers (n = 3 expert judges) and the possibilities for students to monitor their own progress through task completion was revealed as a positive aspect. Furthermore, the creation of personalized alerts to support learning processes also received a very high rating. The final model includes the changes derived from the validation process and suggests a reliable technology-supported intervention in an LMS, which is transferable to a larger scale.

The digital teaching competence of university professors is of vital importance to improving the quality of higher education, and for the strategic positioning of public universities in our country. The purpose of this study is to find out the level of digital competence of Galician university professors, as well as to identify whether there are significant variable-based differences. To this end, a non-experimental design with a descriptive approach and hypothesis contrast is proposed. The sample studied is made up of a total of 610 teachers from the three public universities of Galicia (Spain), who responded to the DigCompEdu Check-In instrument adapted to the Spanish context (Cabero-Almenara & Palacios-Rodríguez, 2020). In general terms, the results show a medium-low level and the existence of significant differences depending on the age, recruitment profile and area of knowledge of the teaching staff. Specifically, the younger teaching and research staff, together with Social and Legal Sciences, have a higher level of competence, whereas tenured teaching and research staff have a lower level of competence with respect to contracted workers. Therefore, training plans should be developed which focus on teaching. Expert advice and personalized methodological support should shift the focus of the intervention radically from technology to teaching.
Full-time Schools in Portugal: Participation and Educational Achievement
Authors: Abrantes Pedro
Published: January 2023

Since its implementation in 2006, Portugal’s full-time schools programme led to a massive increase of curricular enrichment and family-support activities in public schools throughout the country. The literature review brings together important contributions from previous research and assessments of the full-time school programme, including results of similar programmes in other countries and particularities of the Portuguese case. The methodological design is outlined, describing the research questions as well as the variables and categories under consideration. Drawing on extensive administrative data from all public schools in the country, the analysis focuses on participation rates and their link to school location, socioeconomic context, local providers, and educational achievements. The (moderately) positive correlation between participation rates and educational success arises as a key finding, for which possible explanatory factors are discussed. The article concludes with some implications for policy-making and future research on this topic.
Analysing the Impact of Artificial Intelligence and Computational Sciences on Student Performance: Systematic Review and Meta-analysis
Authors: García-Martínez Inmaculada , Fernández-Batanero José María , Fernández-Cerero José , León Samuel P.
Published: January 2023

Artificial intelligence (AI) and computational sciences have aroused a growing interest in education. Despite its relatively recent history, AI is increasingly being introduced into the classroom through different modalities, with the aim of improving student achievement. Thus, the purpose of the research is to analyse, quantitatively and qualitatively, the impact of AI components and computational sciences on student performance. For this purpose, a systematic review and meta-analysis have been carried out in WOS and Scopus databases. After applying the inclusion and exclusion criteria, the sample was set at 25 articles. The results support the positive impact that AI and computational sciences have on student performance, finding a rise in their attitude towards learning and their motivation, especially in the STEM (Science, Technology, Engineering, and Mathematics) areas. Despite the multiple benefits provided, the implementation of these technologies in instructional processes involves a great educational and ethical challenge for teachers in relation to their design and implementation, which requires further analysis from the educational research. These findings are consistent at all educational stages.

Authors: Caldwell-Marin Eldon Glen , Cazorla Miguel , Cañas-Plaza José María
Published: January 2023

This research focuses on whether the use of a cyber-physical robotic system (CPRS) to assist Speech and Language Pathologists (SLP) in a Special Education service is beneficial. The research method is based on a quasi-experiment with a 2k design and a two-way ANOVA, implemented with real high school students over 10 weeks. It was found that the use of this CPRT could improve, preliminarily and as an initial exploratory finding, therapeutic speech effectiveness up to 11.3 percentage points with a statistical confidence of 95%, when SLPs work with students with mild articulation disorder and a restricted time for therapy, but especially when the technology is used without time constraints. It is concluded that assistive CPRT could be a causal factor of improvement in specific treatments performed by SLPs, with the statistical evidence being sufficiently significant (95%) to maintain scientific and educational interest in this research line in the future.
A főbb mezőgazdasági ágazatok költség- és jövedelemhelyzete 2016
Authors: Szili Viktor , Szlovák Sándor
Published: January 2023

A kiadvány a főbb mezőgazdasági ágazatok költség és jövedelemhelyzetét vizsgálja 2016-ra vonatkozóan a magyarországi tesztüzemi rendszerhez tartozó gazdaságok adatai alapján. A feldolgozott adatok a hazai termék-előállítást jellemző, ún. meghatározó árutermelő gazdaságokra vonatkoznak. Az évente megjelenő kiadványsorozat külön fejezetben elemzi a szántóföldi növényeknél, a kertészeti kultúrákban (szántóföldi zöldségek és gyümölcsültetvények) és az állattenyésztési ágazatokban bekövetkező költség- és jövedelemváltozásokat. A vizsgált időszakra az ágazatok többségének szempontjából kedvező időjárási körülmények voltak jellemzőek. Gyakori volt, hogy a 2016-os év rekordtermést hozott. Mivel a ráfordítások mennyiségének alakulása nem volt egyforma a bemutatott ágazatoknál, az önköltségek igen változatosan alakultak, a kertészeti ágazatoknál igen jelentős ingadozások is előfordultak az évek között. A támogatásoknak köszönhetően az egy hektárra jutó ágazati eredmény szinte valamennyi kultúránál pozitív volt. E mutató tendenciái az állattartó ágazatoknál eltérően alakultak, az viszont kiemelendő, hogy a sertéshizlalás 2016-ban továbbra is veszteséges volt a támogatások figyelembevételével is.
