Amid structural changes driven by the greening and digital transformation of the maritime industry, the demand for career transitions of seafarers with onboard experience to shore-based positions—particularly ship superintendents—is steadily increasing. However, the current lack of a systematic education and career development framework to support such transitions poses a critical challenge for shipping companies seeking to secure sustainable human resources. The aim of this study was to develop a competency-based training program that facilitates the effective transition of seafarers to shore-based ship superintendent roles. We integrated a developing a curriculum (DACUM) analysis with competency-based job analysis to achieve this aim. The core competencies required for ship superintendent duties were identified through three expert consultations. In addition, social network analysis (SNA) was used to quantitatively assess the structure and priority of the training content. The analysis revealed that convergent competencies, such as digital technology literacy, responsiveness to environmental regulations, multicultural organizational management, and interpretation of global maritime regulations, are essential for a successful career shift. Based on these findings, a modular training curriculum comprising both common foundational courses and specialized advanced modules tailored to job categories was designed. The proposed curriculum integrated theoretical instruction, practical training, and reflective learning to enhance both applied understanding and onsite implementation capabilities. Furthermore, the concept of a Seafarer Success Support Platform was proposed to support a lifecycle-based career development pathway that enables rotational mobility between sea and shore positions. This digital learning platform was designed to offer personalized success pathways aligned with the career stages and competency needs of maritime personnel. Its cyclical structure, comprising career transition, competency development, field application, and performance evaluation, enables seamless career integration between shipboard- and shore-based roles. Therefore, the platform has the potential to evolve into a practical educational model that integrates training, career development, and policies. This study contributes to maritime human resource development by integrating the DACUM method with a competency-based framework and applying social network analysis (SNA) to quantitatively prioritize training content. It further proposes the Seafarer Success Support Platform as an innovative model to support structured career transitions from shipboard roles to shore-based supervisory positions. Full article

The preservation of paleontological heritage is relevant for paleobiological and geological research, as well as for scientific dissemination. Fossils are indicative of the evolutionary processes, biodiversity, ecology, and geography of the past and require specific geoconservation actions. In Italy, fossils are protected as cultural heritage, and their unauthorized collection and trading are counteracted by a regulatory framework. The local superintendence and law enforcement provide control over the territory, often resorting to the expertise of university paleontologists. In the Calabria region (southern Italy), the collaboration among institutions is yielding interesting results in research, preservation, and public awareness of paleontological heritage. This paper highlights the different approaches to the conservation and promotion of fossils by three museums in Calabria. At the National Archeological Museum of Reggio Calabria, fossils are included in the Prehistory section. The history of life on Earth, with a focus on regional paleontology, characterizes the Museum of the University of Calabria. The Civic Museum of Ricadi exhibits local fossils. Collaboration among these museums and their institutional referents contributes to public awareness and scientific understanding of paleontological heritage, reinforcing the need for conservation and promotion strategies.

The final decades of the eighteenth century saw the significant expansion of botanical propagation and collections across the globe, both as an aesthetic corollary and to provide the underpinning resources for imperialism. The focus of this article is the development of the network between botanists in India and England in the 1790s through the correspondence between William Roxburgh (1751–1815), superintendent of the Botanical Garden in Calcutta from 1793, and Sir James Edward Smith (1759–1820), who as Sarah Law notes, was ‘a focus of correspondence with every serious botanist in the world’ (Law, 2007, 184). Such networks were sustained by letters describing the plants and the treatment they needed, the habitat from which they had been taken, and details of how they had been collected and packed. Epistolary writing between plant hunters and British collectors can be understood, I suggest, as a form of travel writing. This is a form in which correspondence builds connections and relationships between fellow scientists and enthusiasts and the fragmentary focus on place, and the mobility of humans is replaced by close attention to the aesthetic and biological details of plants and the best ways of securing their successful transport across the globe. Using an ecocritical frame, this article explores the position of plants and biological specimens themselves as travellers and considers the ways in which their care and preservation have been articulated through sociable correspondence.

An organization’s success depends on its ability to attract and retain skilled personnel. Superintendents play a critical role in overseeing project sites in the construction industry and can adapt to the increasingly complicated requirements of modern construction projects. This study examines traditional and modern personnel selection methods to determine effective tactics, essential competencies, and emerging trends regarding supervisory personnel. The research methodology follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. First, this study examines traditional and modern selection methods used by organizations and engineering firms to provide a comprehensive overview of the topic and assist in selecting appropriate staff recruitment procedures. Second, the Web of Science, Scopus, and Google Scholar databases were reviewed to identify superintendent selection approaches and competencies, over the period January 2000 to September 2024. A total of 22 relevant papers were analyzed. Superintendent selection processes included questionnaires (57%), interviews (26%), literature reviews (14%), and data-driven AI tools (3%). Forty competency criteria were identified, with the top five being knowledge, communication skills, leadership, health and safety expertise, and commitment. As a result, novel approaches employing Industry 4.0 technologies, including virtual reality (VR), wearable sensing devices (WSDs), natural language processing (NLP), blockchain, and computer vision, are recommended. These findings support a better understanding of how best to identify the most qualified supervisory personnel and provides enhanced methods for evaluating job applicants. Full article

Neonicotinoids, a neuro-effective class of insecticides, are heavily applied in agricultural activities worldwide. Poultry can be exposed to neonicotinoids by several routes, but the knowledge of neonicotinoid’s metabolism in poultry and its associated interspecies differences is highly limited. Hence, this study aims to investigate the species differences in metabolite formations, as well as cytochrome P450 (CYP)-dependent metabolism of four major neonicotinoid compounds, acetamiprid, imidacloprid, clothianidin, and thiamethoxam, in poultry. In vitro biotransformation assays using hepatic microsomes of chicken, ducks, geese, quails, and rats were conducted. Metabolites of neonicotinoids were then screened by LC/Q-TOF and quantified by LC/MS/MS. The results revealed an existence of interspecies differences in the formations of N-[(6-chloro-3-pyridyl) methyl] -N-methyl acetamidine (IM-1-5) of acetamiprid and dm-clothianidin of clothianidin between chicken and other species. In addition, the greatest CYP activities in the metabolism of most neonicotinoid substrates, such as acetamiprid to dm-acetamiprid, imidacloprid to hydroxylated-imidacloprid and imidacloprid-olefin, clothianidin to dm-clothianidin, and thiamethoxam to clothianidin, were found in chicken. These results suggested that the CYPs in chicken may have a greater capacity for metabolism of neonicotinoids compared to other poultry. This study further revealed that the maximum intrinsic clearance of dn-imidacloprid and dn-clothianidin in ducks may be superintended by CYP-mediated nitro-reductions of imidacloprid and clothianidin. Further studies employing CYP recombinant enzymes may be required to elucidate the specific CYP isoforms that may be involved in neonicotinoid metabolism in avian species. Full article

This archival study explores the life and work of Dr. Carrie Weaver Smith (1885–1942), a Progressive Era social worker and prison warden. Specifically, I explore the first phase of her career as a House Physician at the Virginia K. Johnson Home in Dallas, Texas (1911–1915) and as the first Superintendent of the Texas State Training School for Girls in Gainesville, Texas (1916–1925). Using archival research, I detail three conflicts that defined Dr. Smith’s superintendency: her fight to reclassify a youth prison as a school, her challenges to a Ku Klux Klan-dominated legislature, and her refusal to cede authority to a State Board of Control. Together, these conflicts led the Board to terminate Dr. Smith’s position, an outcome that would replay twice more before she retired from prisonwork. I argue that when most reformers made significant concessions, compromising their visions to maintain state funding and political allyship, Dr. Smith stood out for her record of refusal. And yet, like other reformers, she left Texas with the capacity to imprison more women and girls than ever before. Full article

This paper examines school leaders’ evasive attitudes towards race in Salt Lake City (SLC), Utah, between 1969 and 1975. Salt Lake’s unique demographic status as predominantly white and Mormon underscored elements of white anti-Black racism under the guise of innocence. Utilizing critical whiteness theory and historical inquiry to analyze archival documents and interviews, I highlight one white superintendent, Arthur Wiscombe, and his failed attempts to confront anti-Blackness in schools as he navigated his conflicting values of racial justice, good intentions, and white Niceness. Framing the past as prologue, I uncover the historical legacy of white supremacy’s influence on local school policies and leaders’ actions, and make explicit connections to the repetition of these patterns today. Contemporary iterations of white supremacy rely on the same tools of whiteness used during intense periods of integration and racial awareness in Salt Lake City in the 1960s and 1970s. I conclude that white educational leaders must look more closely at the ‘nice’, color-evasive discourse that enables them to maintain power and privilege in their communities. Full article

Pope Francis’s dream for a synodal Church has implications for Catholic schools globally, but what exactly are these consequences? This paper explores Francis’s vision in the context of Canadian Catholic schools in Alberta, Saskatchewan, and the Northwest Territories (NWT), where these schools are fully-funded by the government and enroll nearly a quarter million students. Ten exploratory interviews with chief superintendents from these schools—which formed the basis of a larger study—were analyzed to understand potential connections to Francis’s vision and his four commitments to synodality: focusing on relationships, a culture of encounter, the essentials of the Christian faith, and local decision-making. The pope differentiates synodality from democratic forms of leadership and demands a communal form of listening and discerning God’s Spirit. While the superintendents’ style of leadership appeared to mirror synodality in many ways, predominant issues remain to be explored: an emphasis on relationships upends the status quo and gives new directions for the schools; encountering others will inevitably demand prophetic leadership by the system leaders; leading with the essentials of faith will not please everyone in Catholic schooling; and shared authority among the superintendents, bishops, and trustees requires further dialogue.

Global trade and globalization have driven growth and diversification in the horticultural industry. Fresh grapes, a key product, face challenges of market volatility, trade barriers, and logistics. Market diversification is essential for stability and competitiveness in international trade. This research focused on analyzing market diversification in Peru’s fresh grape exports during the 2013–2022 period, exploring its implications for international trade. A quantitative methodology was used, along with the analysis of publicly recorded data on the website of the National Superintendence of Customs and Tax Administration, specifically exports from companies shipping under the national subheading for Grapes (0806.10.00.00). Diversification was analyzed using the Herfindahl–Hirschman concentration index (HHI), and competitiveness through the Balassa index. The main findings were that between 2013 and 2022, Peruvian grape exports grew in value (CAGR of 12.02%) and volume (CAGR of 12.13%). The sector expanded with an average of 151.2 companies and 59.1 destination markets. Diversification varied: the USA (12.4%), the Netherlands (1.6%), Hong Kong (4.2%), and Mexico (63.2%). The Herfindahl–Hirschman index showed concentration in the USA (4533 in 2020, 4519 in 2022) and stability in companies (2318 in 2014, 2450 in 2022). Finally, it is recommended to strengthen the Peruvian viticultural sector by maintaining geographic diversification through policies seeking new markets, monitoring global trends, constantly analyzing market concentration, and promoting fair competition among participating companies, allowing new ones to enter this sector.

Oral cancer poses a major health challenge in Taiwan, consistently ranking among the highest globally in both incidence and cancer-related mortality. Transoral robotic surgery (TORS) has potential advantages over open surgery, but its long-term oncologic outcomes are not well established. In this study, we sought to elucidate the role of TORS in improving treatment outcomes among oral cancer patients. A case–control study with propensity score matching was conducted in a single teaching hospital in Taiwan. It included 72 oral cancer patients in each group to analyze and compare survival outcomes between the surgical approaches. The TORS group demonstrated a higher negative resection margin rate, a lower mortality risk and better overall survival than the open-surgery group. Multivariate Cox regression analysis confirmed TORS’s association with a reduced risk of death. Kaplan–Meier survival analysis and log-rank tests indicated significantly better survival outcomes for the TORS group across all cancer stages. Moreover, the TORS group exhibited improved overall survival rates for stage III and IV patients compared to the conventional open-surgery group. In conclusion, this study suggests that TORS may offer better overall survival rates and potential advantages over conventional surgery for oral cancer treatment. Full article

On 7 September 2022, the Miami-Dade School Board (MDSB), the governing body of one of the largest school districts in the U.S., rejected a resolution requiring the MDSB to observe October 2022 as LGBTQ History Month and directing the district’s superintendent to investigate the feasibility of providing “information and resources” about landmark LGBTQ Supreme Court cases for optional use in high school government classes. The current study coded the transcript of the September 7 meeting utilizing qualitative research protocols based on grounded theory. The resulting analysis identified three themes (curriculum, coercion, and illegality) associated with comments made by members of the public who opposed the resolution and three themes (curriculum, well-being, and anti-LGBTQ bigotry) associated with comments made by members of the public who supported the resolution. Analysis of the September 7 transcript also identified one primary theme (illegality) associated with MDSB members who opposed the resolution and two themes (disinformation and choice) associated with the MDSB member who supported the resolution. In addition to illustrating certain aspects of a contemporary moral panic in the U.S. and other countries, these results provide insights into how the public and U.S. school board members perceive the appropriateness and limitations of addressing the needs of contemporary LGBTQ students.

Mongolian women enjoy equal rights and actively participate in various sectors of the national economy, including the mineral and mining industry. The Mongolian University of Science and Technology (MUST), the largest university in Mongolia, plays a crucial role in preparing engineers for the Mongolian industry. Within MUST, the School of Geology and Mining Engineering (SGME) stands out as one of the largest schools, boasting a dedicated team of 136 staff members. Impressively, 92 of these staff members are female, constituting a remarkable 67.65% of the total staff. The directorial board of SGME, consisting of 12 members, also demonstrates a noteworthy level of gender diversity, with 5 of its members being female. This represents a proportion of 41.67% and highlights the inclusion of women in decision-making positions. Additionally, it is worth noting that the Geology and Hydrogeology department, one of the five departments within the School, is led by a capable female leader. However, despite the encouraging representation of women among staff and in leadership roles, there is a noticeable disparity in the enrollment and graduation rates of students at SGME. Currently, these rates stand at only about 20–24 percent, indicating the need for further efforts to encourage and support female students in pursuing geology and mining engineering studies. Outside of academia, within the mining industry, the Oyu Tolgoi large-scale mine, which in 2022 employed 20,328 workers, faces a significant gender imbalance. Out of this workforce, only 3577 are women, comprising a mere 18% of the total employees, while the remaining 82% are men. Among the 2997 total employees in the open pit mine, 737 women are employed in various roles, including 66 engineers and technicians, with the remaining 671 in other positions. In the newly opened underground mine, the total number of women employees stands at 2840, including 248 engineers and technicians and 2592 in other roles. Furthermore, on the Board of Directors, there are only 2 women out of a total of 23 managers, and a mere 104 women hold positions as senior staff and superintendents. A comparative analysis between Asia and other global regions reveals that female employment in Mongolia’s mining sector in general, at 18%, closely aligns with Oceania’s rates (17%) and surpasses those of both the broader Asian region (13%) and South America (11%). Addressing these statistical imbalances is crucial to improving gender equality in geoscience and mining. Historically, the mining industry has been male-dominated, but women-led professional geoscience and mining organizations in Mongolia play a vital role in promoting the recruitment, retention, and advancement of women in these industries. Recognizing the significance of gender diversity, these organizations strive to increase the representation of women in leadership positions. Women in leadership bring unique perspectives that contribute to well-rounded decision-making processes within organizations. By acknowledging the importance of gender dynamics, promoting inclusivity, and supporting the professional growth of Mongolian women in geoscience and mining, the overall development and sustainability of these sectors in the country will be greatly enhanced.

This work is part of research conducted within the Di3A Landscape Design and Redevelopment Laboratory at the University of Catania. Its objective is to improve the enjoyment of public spaces through the study of landscape design in highly urbanised and historical areas. The case study used was the historical centre of the city of Catania in Sicily. This study focused on the green aspects of the redevelopment of some open spaces of the Antico Corso district using international and national thematic studies on public spaces as a reference. In particular, the research concentrated on the design of the Garden of Via Biblioteca inside the former Benedictine Monastery of San Nicolò La Rena, a UNESCO world heritage site redeveloped by the famous architect Giancarlo De Carlo. After a careful analysis of the area, we decided to use contemporary project themes with the aim of enhancing the present historical elements and nature-based solutions, which, through the introduction of carefully selected plant species, favour biodiversity in the urban environment. The method adopted was divided into three main phases: (1) spatial analysis; (2) a SWOT analysis method; and (3) the planning and design of the green redevelopment of places to be reconverted into public spaces. This methodology has already been tested on the open spaces of the former Vittorio Emanuele Hospital inside the Antico Corso District, showing how the multidisciplinary approach applied can be replicated in other urban contexts in historical centres. The results of these studies may be useful in the context of urban planning reforms envisaged by Regional Law No. 19/2020 and Regional Law 13/2015 in Sicily and to help the Superintendencies of Landscape and Cultural Heritage to preserve and to enhance historical greenery. The adopted strategies may also be useful in the application of the PUI (Integrated Urban Plan) of the Province of Catania that follows the PNRR (National Plan of Reconstruction and Resilience) parameters to provide local services to the municipalities involved. These pilot projects should be extended to bigger areas. The applicability of the methodology could be tested in other parts of the Municipality of Catania with a particular focus on run-down areas, followed by further testing on territorial sections of the province.

The COVID-19 pandemic brought challenges such as social distancing, health fears, reduced interaction, and increased stress for construction workers. Understanding their changing social and psychological states is crucial for effective management and performance. This study investigated the impact of the pandemic on the managers’ and laborers’ social and psychological well-being states and identified the changes in their social and psychological well-being states affecting project performance before and after the pandemic. Construction professionals, including construction managers, superintendents, and laborers, participated in a survey exploring thirteen social and psychological well-being variables and three performance variables. Data analysis involved paired t-tests and multiple regression. The findings revealed increased levels of anxiety and depression among both managers and laborers after the pandemic, with laborers more severely affected. Managers considered a broader range of variables, while laborers primarily focused on social factors influencing project performance. These disparities suggested that managers should prioritize health and safety measures, fair compensation, team cohesion, and stress management, while laborers’ motivation, work environment, knowledge acquisition, and sense of belonging should receive priority attention. This study contributes to providing managerial implications and guidance for improving the construction workforce, including managers’ and site laborers’ performance in the post-pandemic period.

This research concerns a stylistic and archaeometric study of an ancient marble female bust recently discovered by the Trapani Lombardo family of Reggio Calabria (Southern Italy) and delivered to the Superintendency of Archaeology, Fine Arts, and Landscape for the metropolitan city of Reggio Calabria and Vibo Valentia (SABAP). Based on the first technical, stylistic, and iconographic observations made by the competent bodies, it is a half-length portrait bust from the Roman era, which precisely had the function of faithfully reproducing the physiognomy of the depicted subject. The research aimed to establish the authenticity of the artwork and the origin of the raw material, providing indications about the textural and compositional features and of the alteration products as well as identifying traces of any previous restoration interventions. For these purposes, after a preliminary assessment of the state of conservation of the bust using visual inspections supported by a handheld digital microscope, different analytical techniques, including polarized optical microscopy (OM), scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDX), carbon and oxygen stable isotope ratio determinations (δ¹³C and δ¹⁸O), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR), were used. The results highlighted the originality of the artifact, thus remarking on the importance of the precious archaeological find to be included in the cataloging of tangible assets in the panorama of Italian cultural heritage.
