Migration is a multidimensional process that reshapes identities and communities. This article adopts a polyhedral framework inspired by Pope Francis’s Laudato si’ and Michel Foucault’s concepts of “subjectivation” and the “polyhedron of intelligibility”. Both emphasize spirituality as a transformative force in individuals’ lives and a concept that connects philosophy and theology to support resilience among migrant populations. Using Portugal as a case study, the research examines migration’s historical and contextual landscape and its discursive framework. Through a Lisbon-based research project of interviews with migrants, the study explores the concept of spiritual integration by presenting how spirituality functions to preserve cultural identity while facilitating integration without full assimilation into the host community. Spirituality includes many rules and choices regarding ways of life; therefore, the interview projects’ migrants interpret the concept of spiritual integration in a subjective and polyhedron manner. Creating strong ties to their homes, traditions, cultures, spirituality, sports, and culinary practices, as well as practicing, sharing, and teaching these practices, protects them from total subjection, while learning the host society’s customs and rituals helps them to fit in. The findings show that spirituality serves as an integrational tool, a coping mechanism, and a form of resistance, providing a space for migrants to address and overcome challenges. The article emphasizes the importance of integration policies to create a “safe place” of inclusivity within host communities. Full article

Benzoxazine-based polymer (PBZ) acts as a catalyst for converting CO₂ into cyclic carbonates. PBZ-ODA was successfully synthesized and examined for its catalytic efficiency, proving to be effective under milder conditions with higher yields at room temperature without solvents. Various terminal monoepoxides showed good to excellent conversion rates, while epoxides with aromatic or bulky groups and second oxirane rings also were able to produce corresponding cyclic carbonates. Recyclability tests demonstrated that regenerated PBZ-ODA retained 93% of its catalytic activity. Overall, there was a low catalyst deactivation, as investigated by chemical experiments, SEM-EDX, TGA, FT-IR, XPS, XRD and NMR. The catalyst is reusable and suitable for use in flow or batch reactors. Full article

Artificial intelligence (AI) technologies have been increasingly developed and applied in the audiovisual sector. Over-the-top (OTT) services, directly distributed to viewers via the Internet, are associated with a shift towards automation through algorithmic mediation in audiovisual content led by digital platforms. However, scientific knowledge regarding algorithmic recommender systems and automation in OTT services is not yet systemized; researchers, practitioners, and the public thus lack full awareness about the still largely opaque phenomena. To address this gap, we conduct a systematic literature review in the communication domain (2010–2022) and answer four key research questions: What research objectives have been pursued? What concepts have been developed and/or applied? What methodologies have been privileged? Which OTT platforms have received the most research attention? Challenges and opportunities are highlighted, and an agenda for future research is advanced. Full article

Ma bamboo (Dendrocalamus latiflorus Munro) is a fast-growing woody grass that offers significant economic benefits, including materials for construction, furniture, biofuel, food, and handicrafts. It also provides ecological benefits like soil conservation, wildlife habitats, and carbon sequestration. However, its species distribution patterns are influenced by various factors, including climate (mainly temperature and precipitation), soil attributes, and landscape characteristics such as topography, land use, and vegetation. Understanding these impacts is essential for the sustainable management of D. latiflorus resources and fostering related economic activities. To address these challenges, we developed a comprehensive habitat suitability (CHS) model that integrates climate, soil, and landscape variables to simulate the distribution dynamics of D. latiflorus under different shared socio-economic pathway (SSP) scenarios. An ensemble model (EM) strategy was applied to each variable set to ensure robust predictions. The results show that the current potential distribution of D. latiflorus spans 28.95 × 10⁴ km², primarily located in South China and the Sichuan Basin. Its distribution is most influenced by the annual mean temperature (Bio1), the cation exchange capacity of soil clay particles in the 20–40 cm soil layer (CECc 20–40 cm), vegetation, and elevation. Under future climate scenarios, these habitats are projected to initially expand slightly and then contract, with a northward shift in latitude and migration to higher elevations. Additionally, the Sichuan Basin (Sichuan–Chongqing border) is identified as a climatically stable area suitable for germplasm development and conservation. To conclude, our findings shed light on how climate change impacts the geographic distribution of D. latiflorus, providing key theoretical foundations for its sustainable cultivation and conservation strategies.

The point of departure for this study is an incident in 2020 when a football manager testifying in a Lisbon court used the pronoun of address você and was reprimanded. With the aid of corpus linguistics, we qualitatively analyse the comments (understood as metacomments) that this case generated on media outlets and social media. The main conclusion is that the sociocultural foundations of EP (European Portuguese) address are polarised and unstable based on the following: the nexus between forms of address and the expression of (im)politeness is often rejected, with concerns that a complex system of address might impede an egalitarian society; despite this, discernment remains a core facet, expressed in the concern for finding appropriate sociolinguistic rules so as to arrive at forms understood as intrinsically (im)polite. Furthermore, a binary T/V dimension does not apply to the EP system, and although a N (neutral) dimension should be added, the polarised perceptions of EP address preclude clear candidates not only for the N platform but also, to an extent, for the V dimension. Fifty years after the 1974 ‘Carnation’ Revolution that initiated the transition to democracy in Portugal, EP conceptualisations of address show that sociocultural concerns for an egalitarian society coexist with persistent concerns for hierarchy and rules.

Although the study of migration has shifted its focus from an individual perspective (on those who emigrate) to also include their integration networks in the country of destination, it is also necessary to consider the dynamics with their families in the country of origin. With an integral focus on the analysis of Portuguese transnational families, this paper aims to reflect on how the connection between those who emigrate and those who stay can promote greater resilience, presenting best practices for interventions among these dynamics and generations. Using a post-positivist paradigm and semi-structured interviews, we developed a qualitative approach with three exploratory studies: (1) Portuguese young adults living abroad (N = 22); (2) parental figures living in Portugal with adult children living abroad (N = 20); and (3) experts in the fields of academic and psychosocial work with similar people (N = 8). The data were analyzed using N-Vivo software (ed.11 and 14). The general results lead us to reflect on the dynamics of relationships, where digital and face-to-face spaces participate simultaneously, even though there are different challenges and ways of using digital means. We also found a change in expectations regarding the norms and values perceived by this generation of emigrants, which leads us to consider the importance of intercultural values since transnational families greatly increase transculturality, which can promote resilience among these groups. The data also alert us to the need to train intervention professionals in multidisciplinary areas, always taking the cultural context into account. Full article

Analyzing stochastic algorithms for comprehensive performance and comparison across diverse contexts is essential. By evaluating and adjusting algorithm effectiveness across a wide spectrum of test functions, including both classical benchmarks and CEC-C06 2019 conference functions, distinct patterns of performance emerge. In specific situations, underscoring the importance of choosing algorithms contextually. Additionally, researchers have encountered a critical issue by employing a statistical model randomly to determine significance values without conducting other studies to select a specific model for evaluating performance outcomes. To address this concern, this study employs rigorous statistical testing to underscore substantial performance variations between pairs of algorithms, thereby emphasizing the pivotal role of statistical significance in comparative analysis. It also yields valuable insights into the suitability of algorithms for various optimization challenges, providing professionals with information to make informed decisions. This is achieved by pinpointing algorithm pairs with favorable statistical distributions, facilitating practical algorithm selection. The study encompasses multiple nonparametric statistical hypothesis models, such as the Wilcoxon rank-sum test, single-factor analysis, and two-factor ANOVA tests. This thorough evaluation enhances our grasp of algorithm performance across various evaluation criteria. Notably, the research addresses discrepancies in previous statistical test findings in algorithm comparisons, enhancing result reliability in the later research. The results proved that there are differences in significance results, as seen in examples like Leo versus the FDO, the DA versus the WOA, and so on. It highlights the need to tailor test models to specific scenarios, as p-value outcomes differ among various tests within the same algorithm pair. Full article

The first few decades of the twenty-first century have posed various challenges to humankind such as the worldwide impact of the changing patterns of globalization processes, economic crises, the pandemic, the war in Ukraine, and the specter of deglobalization illustrate. The unknown and unpredictable future is a reason for utmost concern for the contemporary society that Byung-Chul Han characterizes as an “achievement society”—one that is dominated by “excessive positivity” and that has evolved into a “doping society”. This “palliative society” is such because it is unable to cope with pain, and it is marked by a kind of permanent analgesia that prevents urgent reforms from taking place. In this essay, I examine how Pope Francis’s encyclical letters Laudato Si’ (2015) and Fratelli Tutti (2020)—by calling for an integral ecology (which connects environmental, economic, political, social, cultural, and ethical issues), social friendship, solidarity, and the common good—instill hope in the burnout society that Han reflects upon, urge action toward, and encourage changes to overcome in the current environmental and human crisis, as well as to building a diverse future that is not palliative.

In the face of globalization and diversity in the United Arab Emirates, the post-oil generation of Emiratis face unique challenges in navigating their cultural and national identities. Previously published research and scholarly works have engaged in complex discourse around Emirati identities, describing them as a population with similar genealogical backgrounds, ancestry, history, and cultural values. However, the element of heterogeneity among Emiratis remains highly under-examined. This research paper will examine the experiences of Emiratis with dual identities in the UAE, investigating their perceptions, attitudes, and narratives on being labeled as the “other” by their compatriots; exploring the spaces where hybrid Emiratis, locally known as “halfies”, choose to reveal and conceal their multiplicity. In order to examine this complex socio-cultural phenomenon, semi-structured interviews with twenty Emiratis with twin identities were employed for this empirical study. The examination of the interviews uncovered the difficulties that individuals with mixed heritage encounter, as well as their strategies for overcoming these obstacles in order to find acceptance in a society that values a shared national identity. The research findings contribute to the scholarship of Emirati identity construction. Full article

Introduction: The objective was to evaluate the poisoning severity score (PSS) as an early prognostic predictor in patients with wasp stings and identify associated clinical characteristics and risk factors for mortality. Methods: A total of 363 patients with wasp stings at Suining Central Hospital between January 2016 and December 2018 were enrolled. Within the first 24 h of admission, the poisoning severity score (PSS) and the Chinese expert consensus on standardized diagnosis and treatment of wasp stings (CECC) were utilized for severity classification, and their correlation was examined. Patients were then divided into survival and death groups based on discharge status. Logistic regression analysis was employed to analyze factors influencing patients’ outcomes. Results: The mortality of wasp sting patients was 3.9%. The PSS and CECC were found to correlate for severity classification. Additionally, female gender, age, number of stings, and PSS were identified as independent risk factors for mortality in wasp sting patients. Combining these four factors yielded an AUC of 0.962 for predicting death. Conclusions: PSS aids in early severity classification of wasp stings. Female gender, age, number of stings, and PSS were independent mortality risk factors in these patients. Full article

Metaheuristic optimization is considered one of the most efficient and powerful techniques of recent decades as it can deal effectively with complex optimization problems. The performance of the optimization technique relies on two main components: exploration and exploitation. Unfortunately, the performance is limited by a weakness in one of the components. This study aims to tackle the issue with the exploration of the existing jellyfish search optimizer (JSO) by introducing a hybrid jellyfish search and particle swarm optimization (HJSPSO). HJSPSO is mainly based on a JSO structure, but the following ocean current movement operator is replaced with PSO to benefit from its exploration capability. The search process alternates between PSO and JSO operators through a time control mechanism. Furthermore, nonlinear and time-varying inertia weight, cognitive, and social coefficients are added to the PSO and JSO operators to balance between exploration and exploitation. Sixty benchmark test functions, including 10 CEC-C06 2019 large-scale benchmark test functions with various dimensions, are used to showcase the optimization performance. Then, the traveling salesman problem (TSP) is used to validate the performance of HJSPSO for a nonconvex optimization problem. Results demonstrate that compared to existing JSO and PSO techniques, HJSPSO contributes in terms of exploration and exploitation improvements, where it outperforms other well-known metaheuristic optimization techniques that include a hybrid algorithm. In this case, HJSPSO secures the first rank in classical and large-scale benchmark test functions by achieving the highest hit rates of 64% and 30%, respectively. Moreover, HJSPSO demonstrates good applicability in solving an exemplar TSP after attaining the shortest distance with the lowest mean and best fitness at 37.87 and 36.12, respectively. Overall, HJSPSO shows superior performance in solving most benchmark test functions compared to other optimization techniques, including JSO and PSO. As a conclusion, HJSPSO is a robust technique that can be applied to solve most optimization problems with a promising solution. Full article

Child drawing development optimization (CDDO) is a recent example of a metaheuristic algorithm. The motive for inventing this method is children’s learning behavior and cognitive development, with the golden ratio being employed to optimize the aesthetic value of their artwork. Unfortunately, CDDO suffers from low performance in the exploration phase, and the local best solution stagnates. Harmony search (HS) is a highly competitive algorithm relative to other prevalent metaheuristic algorithms, as its exploration phase performance on unimodal benchmark functions is outstanding. Thus, to avoid these issues, we present CDDO–HS, a hybridization of both standards of CDDO and HS. The hybridized model proposed consists of two phases. Initially, the pattern size (PS) is relocated to the algorithm’s core and the initial pattern size is set to 80% of the total population size. Second, the standard harmony search (HS) is added to the pattern size (PS) for the exploration phase to enhance and update the solution after each iteration. Experiments are evaluated using two distinct standard benchmark functions, known as classical test functions, including 23 common functions and 10 CEC-C06 2019 functions. Additionally, the suggested CDDO–HS is compared to CDDO, the HS, and six others widely used algorithms. Using the Wilcoxon rank-sum test, the results indicate that CDDO–HS beats alternative algorithms. Full article

α-tocopherol is the physiologically most active form of vitamin E, with numerous biological activities, such as significant antioxidant activity, anticancer capabilities, and anti-aging properties. However, its low water solubility has limited its potential use in the food, cosmetic, and pharmaceutical industries. One possible strategy for addressing this issue is the use of a supramolecular complex with large-ring cyclodextrins (LR-CDs). In this study, the phase solubility of the CD26/α-tocopherol complex was investigated to assess the possible ratios between host and guest in the solution phase. Next, the host–guest association of the CD26/α-tocopherol complex at different ratios of 1:2, 1:4, 1:6, 2:1, 4:1, and 6:1 was studied by all-atom molecular dynamics (MD) simulations. At 1:2 ratio, two α-tocopherol units interact spontaneously with CD26, forming an inclusion complex, as supported by the experimental data. In the 2:1 ratio, a single α-tocopherol unit was encapsulated by two CD26 molecules. In comparison, increasing the number of α-tocopherol or CD26 molecules above two led to self-aggregation and consequently limited the solubility of α-tocopherol. The computational and experimental results indicate that a 1:2 ratio could be the most suitable stoichiometry to use in the CD26/α-tocopherol complex to improve α-tocopherol solubility and stability in inclusion complex formation.

This study consisted of a content analysis of parenting portrayals in the 40 most popular Portuguese male and female content producers on YouTube and Instagram, on a sample of content published in 2019. Female creators give disproportionately greater attention to parenting and are the ones depicting everyday labor related to it, whereas male creators show themselves as fathers in happy and fun moments. By way of their popularity and visibility on social media platforms, and as supported by the social media platforms and advertising realms, celebrities and influencers are amplifying the traditional division of parenting labor through the mechanisms of a postfeminist, hyper-individualistic discourse emphasized by female influencers and celebrities, and of humoristic content that confirms gender stereotypes without social punishment, deployed by entertainment personalities, both male and female.

Postoperative atrial fibrillation (POAF) is the most common arrhythmia after cardiac surgery in conventional extracorporeal circulation (CECC), with an incidence of 15–50%. The POAF pathophysiology is not known, and no blood biomarkers exist. However, an association between increased ferritin levels and increased AF risk, has been demonstrated. Based on such evidence, here, we evaluated the effectiveness of ferritin and other haematological parameters as POAF risk biomarkers in patients subjected to cardiac surgery. We enrolled 105 patients (mean age = 70.1 ± 7.1 years; 70 men and 35 females) with diverse heart pathologies and who were subjected to cardiothoracic surgery. Their blood samples were collected and used to determine hematological parameters. Electrocardiographic and echocardiographic parameters were also evaluated. The data obtained demonstrated significantly higher levels of serum ferritin, red cell distribution width (RDW), and platelets (PLTs) in POAF patients. However, the serum ferritin resulted to be the independent factor associated with the onset POAF risk. Thus, we detected the ferritin cut-off value, which, when ≥148.5 ng/mL, identifies the subjects at the highest POAF risk, and with abnormal ECG atrial parameters, such as PW indices, and altered structural heart disease variables. Serum ferritin, RDW, and PTLs represent predictive biomarkers of POAF after cardiothoracic surgery in CECC; particularly, serum ferritin combined with anormal PW indices and structural heart disease variables can represent an optimal tool for predicting not only POAF, but also the eventual stroke onset.
