Domestic Tourism Preferences of Polish Tourist Services’ Market in Light of Contemporary Socio-economic Challenges
Authors: Chomać-Pierzecka Ewa , Stasiak Jacek 
Published: May 2024

AbstractThe available literature insufficiently explores the themes of socio-economic conditions determining the state of Polish tourism sector. In addition to the COVID-19 pandemic, the war in Ukraine and its economic impact is an important factor creating the contemporary operating reality. Recognising the important role of tourism in the Polish economy and the diagnosed gap in the literature, it was considered reasonable and valuable to scientifically identify the presented issues, with particular emphasis on the national dimension of tourism activity. The aim of this paper is to analyse and evaluate domestic tourists’ preferences in the tourism sector in Poland and in particular, in the coastal town of Ustka. A survey was conducted to investigate these preferences. The methodology in terms of detailed research is statistical survey instruments—correlation of variables, logit function model together with odds ratio findings, for the estimation of variables, using PQstat software. Findings point to the significant impact of external environment conditions on the state of the domestic tourism industry in Poland. The key condition negatively affecting the sales of domestic tourism services is the impoverishment of the Polish community, which is a derivative of high inflation caused by the pandemic and reinforced by the armed conflict in Ukraine. Expenditure on travel is significantly reduced in domestic visitors' budgets, the length of journeys is shortened, and the cost of accommodation is optimized. The above, on the one hand, increases flexibility and reduces the cost of travel, while on the other hand, it has a negative impact on the sales value of tourism services of entities running in the explored industry. The results enrich the source material that can be used by decision-makers in designing a marketing strategy for the development of the domestic tourism services sector in Poland.

AbstractThis study presents the evaluation results of the “ATANA” research program, which focuses on a platform that integrates the creation and management of narratives associated with cultural tourism applications. Considering the objectives of this study and the target audience, the proposed method could be beneficial to museums and cultural institutions by providing interactive tours and enhancing the overall visitor experience. Additionally, it can be advantageous for cultural tourism stakeholders and local businesses in the surrounding areas as it may attract more tourists and increase footfall. The platform leverages augmented reality and narrative techniques within an ambient-intelligence environment that encompasses a museum and its surrounding landmarks. The case study pertains to the Kotsanas Museum of Ancient Greek Technology (MAET), an institution with a continuous presence for 25 years, represented through a network of museums on the same theme located in Ancient Olympia and Athens, and an exhibition in which the organisation has participated in Malta. The methodology employed leverages the principles of ambient intelligence, enabling tourists to traverse the historic centre of Athens or the archaeological site of the Olympia, and to explore ancient Greek technological inventions through a mobile application supporting augmented reality. The proposed approach also supported the participation of MAET in an exhibition in Malta by projecting a variety of 3D inventions presented in MAET museums through augmented reality.
Metaverse and Education for Sustainable Global Citizenship: Ethical Paradoxes
Authors: Fonseca Josélia , Borges-Tiago Teresa 
Published: May 2024

AbstractThe emergence of the metaverse and the urgent need for educating sustainable global citizenship raises critical ethical considerations. If on the hand, the metaverse has the potential to bring together individuals from diverse backgrounds and cultures, creating an international community focused on sustainability and global citizenship. On another hand, given its characteristics as a virtual metaphor, the metaverse can create artificial societies inhabited by alter egos, capable of violent situations, based on the moral uncompromising of individuals under the guise of a fictitious personality. In this article, we intend to reflect on including the metaverse in the education for sustainable global citizenship, alerting to possible ethical dangers that may arise from it, and supporting this reflection methodologically with a bibliometric study on the subject. The metaverse presents an opportunity to integrate ethics, sustainability, and global citizenship into education. The metaverse paradox comprehends the dialectical relationship between the metaverse, ethics, global citizenship, and sustainability, constituting an excellent opportunity to promote ethics education for global citizenship. Harnessing the immersive and interactive nature of the metaverse, individuals can develop a deeper understanding of the interconnectedness of global issues and their ethical implications. Educating with and for the metaverse can contribute to the development of an ethical and moral digital consciousness, fostering the development of values and skills such as responsibility, fairness, empathy, and digital literacy, which are essential to empower individuals to take sustainable action and cultivate a global community committed to creating a more sustainable future.

AbstractLiving in the age of technology, universities are in need of keeping up with the development of the means of communication and the way new generations of students use these means. The purpose of the research was to identify the online promotion strategies used by the best European universities that provide master programs in communication based on a top made by Times Higher Education, in order to create an online promotion and communication procedure for Transilvania University of Brasov and other universities. Firstly, we analyzed the way the first 20 European universities with master programs in communication, according to a top made by The Times Higher Education, promote themselves online. Secondly, in order to be able to make a comparison and break down rules of good practice we analyzed the online promotion of 5 universities that occupy lower positions in the top. The universities were analyzed based on an adapted content grid with 29 criteria, including: contact information, real time assistance, social media instruments, information about: study programs, campus, employees, admission. Our results showed that the best European universities offering masters programs in communication, use various integrated online promotion and communication strategies and utilize combinations of tools that match their profile. Therefore, while there are similarities between the strategies used by the best European universities and the European universities with lower positions in the top, strategies of the best ranked universities and their promotion and communication methods can be adapted and used by other universities in order to improve their procedure of online promotion and communication.
Automatic Generation of Restaurant Reviews Using Natural Language Processing
Authors: Maldonado Castillo Idalia , Aguirre Miranda Ignacio Adrián , Olvera Mendoza Alexis 
Published: May 2024

AbstractCurrently, there is plenty of information available on restaurant rating platforms, but sometimes it can be contradictory or difficult to analyze in depth. An important challenge for consumers is searching for useful opinions and making decisions based on reviews usually obtained from different social networks or rating platforms. This project addresses this issue through the design, development, and implementation of a system that generates global recommendations for a set of restaurants based on the analysis of reviews using Natural Language Processing (NLP) techniques. The system is based on a corpus of restaurant reviews in Mexico City, from which relevant aspects are extracted and synthesized to generate comprehensive reviews from various sources. The system can also evaluate customer satisfaction by identifying the positive and negative aspects mentioned in their reviews. In this way, it provides comprehensive information that helps diners make informed decisions. By gathering data from various sources, the system classifies and analyzes the information, providing an analysis rather than just displaying data. Another important aspect is that the project contributes to the promotion of the gastronomic offer in Mexico City, supporting tourism in a more informed way. By integrating customer perspectives, a more complete and realistic view of the restaurant experience is obtained. The importance of this project lies in the empirical evidence showing that consumer reviews are influenced by the average rating and the number of reviews. Given the overwhelming number of options and the need to provide relevant information efficiently, this project offers a solution by generating detailed reviews based on aggregated information from multiple sources, including consumer reviews and influencer critiques.
On Convergences and Divergences: Gendered and Layered Political Citizenship in Ghana and Uganda
Authors: Madsen Diana Højlund , Ahikire Josephine 
Published: May 2024

AbstractThis chapter explores the dynamics of contemporary political citizenships in West African Ghana and East African Uganda with a focus on junctures of convergences and divergences shaping the pathways for gendered in-/exclusions of citizenships. It interrogates the ways women’s political citizenships have developed and the pathways to power in the two countries. It draws on the notion of Ubuntu and afro communitarianism as a pathway for understanding collective political citizenships and belongings as an alternative to Western state-centric and individualised notions of citizenship. By mapping historical trajectories, the chapter seeks to understand the continuities, and changes defining present gendered citizenships. Despite being on similar paths in terms of the development of political systems, institutions, and the gender subtext in the post-colonial eras, the two countries have developed unevenly. Whereas Uganda is characterised by authoritarian features with a relative high level of women’s political representation, the more democratic Ghana has a low level of women’s political representation. It concludes that related to the notion of Ubuntu the achievement of women’s substantive political citizenship will be located within women’s collective lived realities and demands a broad-based intersectional mobilisation.
Pseudo-scalar meson spectral properties in the chiral crossover region of QCD

Published: May 2024

Abstract
Determining the type of excitations that can exist in a thermal medium is key to understanding how hadronic matter behaves at extreme temperatures. In this work we study this question for pseudo-scalar mesons comprised of light-strange and strange-strange quarks, analysing how their low-energy spectral properties are modified as one passes through the high-temperature chiral crossover region between T = 145.6 MeV and 172.3 MeV. We utilise the non-perturbative constraints satisfied by correlation functions at finite temperature in order to extract the low-energy meson spectral function contributions from spatial correlator lattice data in Nf = 2 + 1 flavour QCD. The robustness of these contributions are tested by comparing their predictions with data for the corresponding temporal correlator at different momentum values. We find that around the pseudo-critical temperature Tpc the data in both the light-strange and strange-strange channels is consistent with the presence of a distinct stable particle-like ground state component, a so-called thermoparticle excitation. As the temperature increases this excitation undergoes collisional broadening, and this is qualitatively the same in both channels. These findings suggest that pseudo-scalar mesons in QCD have a bound-state-like structure at low energies within the chiral crossover region which is still strongly influenced by the vacuum states of the theory.
Treatment of unstable forearm fractures at the metaphyseal-diaphyseal junction in children: antegrade ESIN vs. transepiphyseal intramedullary K-wire fixation

Published: May 2024

Abstract
Background
Treatment of unstable forearm fractures in the metaphyseal-diaphyseal junction (MDJ) zone is still a matter of debate. Major drawbacks of all types of fixations include either invasiveness, technical impracticality, or lack of acceptance by patients. This study reports results after antegrade ESIN (a-ESIN) compared to transepiphyseal intramedullary K-wire (TIK) for unstable MDJ forearm fractures.

Methods
The MDJ of the forearm was defined as the square over the joints of both forearm bones subtracted with the square over the metaphysis of the radius alone. The data of 40 consecutive patients < 16 years of age who were treated either by a-ESIN (later treatment period) or TIK (early treatment period) for an unstable MDJ forearm fracture at a single high-volume pediatric trauma center were retrospectively analyzed.

Results
The average age was slightly lower in the first group (TIK = 7.42 years; a-ESIN = 10.5 years). An additional ulna fracture was found in 50% of cases and was treated with a classic antegrade ESIN in 10/20 (TIK) and 6/20 cases (a-ESIN). Additional plaster cast immobilization was performed in all cases with TIK and in three cases with a-ESIN. After TIK, no complication, malalignment, or functional limitation occurred. After a-ESIN, 19/20 patients had an event-free course with stable retention and healing without axial malalignment. In one case, a temporary sensor dysfunction occurred. The same patient suffered a refracture two months after the original trauma, which required a closed reduction. Metal removal was performed after 84 days (TIK) and 150 days (a-ESIN). The outcome in all patients was good.

Conclusion
Both a-ESIN and TIK are minimally invasive procedures that are technically easy to perform. Both methods are safe and lead to a complete restoration of the forearm’s range of motion. The decisive advantage of a-ESIN is the possibility of postoperative immobilization-free rehabilitation.

Abstract
Objectives
To examine differences in behavior problems between children from intended versus unintended pregnancies, and to estimate how much the difference in problem behavior would be reduced if postnatal depression was eliminated and social support was increased within 6 months after birth.

Methods
Data from the Generation R Study were used, a population-based birth cohort in Rotterdam, the Netherlands (N = 9621). Differences in child internalizing and externalizing behavior at ages 1.5, 3, 6, 9 and 13 years between pregnancy intention groups were estimated using linear regression. Associations of postnatal depression and social support with internalizing and externalizing problems were also estimated using linear regression. Child behavior outcomes where compared before and after modelling a situation in which none of the mothers experienced a postnatal depression and all mother experienced high social support.

Results
Most pregnancies (72.9%) were planned, 14.8% were unplanned and wanted, 10.8% were unplanned with initially ambivalent feelings and 1.5% with prolonged ambivalent feelings. Children from unplanned pregnancies had more internalizing and externalizing problems at all ages as compared to children from a planned pregnancy, especially when ambivalent feelings were present. Hypothetically eliminating on postnatal depression reduced the differences in internalizing and externalizing problems by 0.02 to 0.16 standard deviation. Hypothetically increasing social support did not significantly reduce the difference in internalizing and externalizing problems.

Conclusions
Children from an unplanned pregnancy have more behavior problems, in particular when mothers had prolonged ambivalent feelings. Eliminating postnatal depression may help to reduce the inequality in child behavior related to pregnancy intention.
Internal exposure to heat-induced food contaminants in omnivores, vegans and strict raw food eaters: biomarkers of exposure to acrylamide (hemoglobin adducts, urinary mercapturic acids) and new insights on its endogenous formation

Published: May 2024

AbstractThe urinary mercapturic acids N-acetyl-S-(2-carbamoylethyl)-L-cysteine (AAMA) and N-acetyl-S-(2-carbamoyl-2-hydroxyethyl)-L-cysteine (GAMA) are short-term biomarkers of exposure from acrylamide and its metabolite glycidamide, respectively. The medium-term exposure to acrylamide and glycidamide is monitored by the adducts N-(2-carbamoylethyl)-Val (AA-Val) and N-(2-carbamoyl-2-hydroxyethyl)-Val (GA-Val) in hemoglobin (Hb), respectively. Three questions were addressed by application of these biomarkers in two diet studies including 36 omnivores, 36 vegans and 16 strict raw food eaters (abstaining from any warmed or heated food for at least four months): first, what is the internal acrylamide exposure following a vegan or a raw food diet in comparison to that in omnivores? Second, did the exposure change between 2017 and 2021? And third, what is the stability over time of AAMA/GAMA excretion compared to that of AA-Val/GA-Val levels in Hb between both time points? Median urinary AAMA excretion per day in non-smoking omnivores, vegans and raw food eaters were 62.4, 85.4 and 15.4 µg/day, respectively; the corresponding median AA-Val levels were 27.7, 39.7 and 13.3 pmol/g Hb, respectively. Median levels in strict raw food eaters were about 25% (AAMA excretion) and 48% (AA-Val) of those in omnivores. In comparison to 2017, AAMA and GAMA excretion levels were hardly altered in 2021, however, levels of AA-Val and GA-Val in 2021 slightly increased. There was a weak correlation between AAMA excretion levels determined four years apart (rS = 0.30), and a moderate correlation between levels of AA-Val (rS = 0.55) in this timeframe. Our data in strict raw food eaters confirm a significant endogenous formation to acrylamide in a size range, which is—based on the levels of AA-Val—distinctly higher than reported previously based on levels of urinary AAMA excretion. The relatively lower AAMA excretion in raw food eaters likely represents a lower extent of glutathione conjugation due to missing hepatic first-pass metabolism in case of endogenous formation of acrylamide, which leads to a higher systemic exposure.
Irrigation optimization enhances water management and tree performance in commercial citrus groves on sandy soil

Published: May 2024

AbstractCitrus production in Florida accounts for nearly 50% of national production in the United States. The goal of this study was to determine the impact of varying irrigation levels on tree growth, leaf nutrient concentrations, and water relations at selected citrus tree densities. During most of the year, significant water distribution and movement were detected across soil horizons as a function of irrigation applied and capillary water rising from the water table. As a result, significant fibrous root length densities (FRLD), median root lifespan, and leaf nutrient concentration were observed in the three-row and two-row experiments with deficit (50%-crop evapotranspiration, (ETc) and moderate (78%-ETc) irrigation regimes, respectively. Stomata conductance and stem water potential (y) portray less water stress of the trees when they received moderate irrigation in the low and moderate tree densities than the highest tree density. Moderate irrigation triggered FRLD and improved root survival probability and root lifespan. As a result, irrigation management improved water availability, plant nutrition, and tree growth while efficiently utilizing resources.

Abstract
Objective
To determine the influence of arterial hypertension (AHT), sex, and the interaction between both left- and right ventricular (LV, RV) morphology, function, and tissue characteristics.

Methods
The Hamburg City Health Study (HCHS) is a population-based, prospective, monocentric study. 1972 individuals without a history of cardiac diseases/ interventions underwent 3 T cardiac MR imaging (CMR). Generalized linear models were conducted, including AHT, sex (and the interaction if significant), age, body mass index, place of birth, diabetes mellitus, smoking, hyperlipoproteinemia, atrial fibrillation, and medication.

Results
Of 1972 subjects, 68% suffered from AHT. 42% with AHT and 49% controls were female. Females overall showed a higher ejection fraction (EF) (LV: regression coefficient +2.4% [95% confidence interval: 1.7; 3.1]), lower volumes and LV mass (−19.8% [−21.3; −18.5]), and prolonged native septal T1 (+22.1 ms [18.3; 25.9])/T2 relaxation times (+1.1 ms [0.9; 1.3]) (all p < 0.001) compared to males. Subjects with AHT showed a higher EF (LV: +1.2% [0.3; 2.0], p = 0.009) and LV mass (+6.6% [4.3; 9.0], p < 0.001) than controls. The interaction between sex and AHT influenced mapping. After excluding segments with LGE, males (−0.7 ms [−1.0; −0.3 | ) and females with AHT (−1.1 ms [−1.6; −0.6]) showed shorter T2 relaxation times than the sex-respective controls (p < 0.001), but the effect was stronger in females.

Conclusion
In the HCHS, female and male subjects with AHT likewise showed a higher EF and LV mass than controls, independent of sex. However, differences in tissue characteristics between subjects with AHT and controls appeared to be sex-specific.

Clinical relevance statement
The interaction between sex and cardiac risk factors is an underestimated factor that should be considered when comparing tissue characteristics between hypertensive subjects and controls, and when establishing cut-off values for normal and pathological relaxation times.

Key Points

There are sex-dependent differences in arterial hypertension, but it is unclear if cardiac MR parameters are sex-specific.

Differences in cardiac MR parameters between hypertensive subjects and healthy controls appeared to be sex-specific for tissue characteristics.

Sex needs to be considered when comparing tissue characteristics in patients with arterial hypertension to healthy controls.
