Port container throughput prediction method based on SSA-SVM

To improve the prediction accuracy of the port cargo throughput and the applicability of the prediction model, and then provide data support for the port construction to meet the needs of port decision-making, take the monthly cargo throughput data of Shanghai Port from January 2009 to December 2022 as an example, use Pearson correlation analysis to screen 12 import and export impact factors. This paper improves the traditional SVM model, uses SSA (Sparrow Search Algorithm) to optimize the parameters c and g in SVM, and uses the model to predict. Compared with the model that uses the grid search algorithm to optimize the parameters of SVM, the model has a significant improvement in fitting and robustness, its predicted value is closer to the actual value, the prediction performance is better, and it can better reflect the actual state of the port.

Exploring modern bathymetry: A comprehensive review of data acquisition devices, model accuracy, and interpolation techniques for enhanced underwater mapping

Building a high-precision bathymetry digital elevation model is essential for navigation planning, marine and lake resource planning, port construction, and underwater archaeological projects. However, existing bathymetry methods have yet to be effectively and comparatively analyzed. This paper comprehensively reviews state-of-the-art bathymetry methods, including data acquisition techniques, model accuracy, and interpolation algorithms for underwater terrain mapping. First, We assess the merits and drawbacks of novel data acquisition devices, such as single-beam/multi-beam echo sounders and light detection and ranging systems. After that, we analyze the accuracy of the ETOPO1, GEBCO_2022 and SRTM15 to provide valuable insights into their performance. Furthermore, we evaluate ANUDEM, Inverse Distance Weighting, Kriging and Nearest Neighbor interpolation algorithms in different underwater terrains by comparing their applicability, reliability, and accuracy in various underwater environments. Finally, we discuss the development trends and challenges in underwater bathymetry technology and offer a forward-looking perspective on the future of this essential field.

A New Inquiry into the Ideological and Political Education of College Students in the Context of Free Trade Port

Abstract Ideological and political education is the fundamental guarantee to realize the goal and direction of college students’ talent training, and the key factor of Hainan free trade port construction is talent. Therefore, this paper carries out a new exploration of the ideological and political education of college students based on the background of free trade ports and selects the SPOC hybrid teaching model to carry out the ideological and political education of college students. Using the AHP-FCE evaluation mechanism, we construct the AHP three-level evaluation indexes and establish the FCE evaluation factor set. By calculating the affiliation matrix and hierarchical weight vector of the three-level index set, we make a comprehensive evaluation of the feasibility and effectiveness of the SPOC hybrid teaching model in ideological and political teaching and prove that it can improve students’ ideological and political performance and cultivate talents. In this paper, we conducted experiments in five colleges and universities and proved that students’ performance in ideology and politics under the SPOC hybrid teaching model increased from only 60 passing marks to more than 75 marks per capita. The teachers’ teaching time of ideology and politics also increased by at least 5 hours and at most 7 hours based on the original one. It can be seen that the SPOC teaching model applied to the ideological and political education of college students can significantly improve the ideological and political achievements of students, and can provide a steady stream of high-quality talents for the construction of the Hainan free trade port.

Revisiting Sir Robert Bristow's ‘India’: A post-colonial analysis of Cochin Saga

Sir Robert Bristow, popularly called Bristow Sahib, is recognized as a path-breaker in the field of port construction in the historical consciousness and cultural imaginary of the people of Kerala, the southernmost state of India. His memoir, Cochin Saga, published in 1959, records both his professional experiences as a harbour engineer and his personal reminiscences as a British resident posted in Cochin. Maritime scholarship has paid scant attention to this literary document, which is a crucial record of how Bristow succeeded in winning hearts in an alien culture, overcoming hostile environmental situations. This article attempts to reconsider Bristow's memories as recorded in Cochin Saga from a post-colonial perspective, and tries to examine whether Bristow's accounts fall prey to employing universalizing tendencies and a hegemonic world view of India and its culture.

Resilience Evaluation of Ports along the Maritime Silk Road from the Perspective of Investment and Construction

Since the establishment of the “Belt and Road” initiative, the investment and construction of ports along the 21st Century Maritime Silk Road have received extensive attention from the international community. The evaluation of ports is of great significance to investors’ investments and construction of ports around the world, so it is very necessary to establish a reasonable port evaluation system. At present, there are few studies on defining and evaluating port resilience, and the existing port evaluation index system has defects. Therefore, according to the similarity between cities and ports, this paper introduces the concept of “three-dimensional space” and the “system of systems” theory of cities and divides the resilience of ports along the Maritime Silk Road into three-dimensional spaces of “physical-society-information.” The CRITIC-entropy method and the TOPSIS method constructed a port resilience evaluation model along the Maritime Silk Road and quantitatively evaluated and analyzed the comprehensive resilience and subspatial resilience of 28 ports along the 21st Century Maritime Silk Road. The results show that the route network port degree, the annual throughput of the port container, and the number of fixed broadband subscribers per 100 people are the key indicators that affect the port’s physical space resilience, social space resilience, and information space resilience. Also, coordinated physical, social, and information spatial resilience development plays a catalytic role in improving overall resilience. Therefore, the investment of ports along the Maritime Silk Road should adopt corresponding and more targeted investment plans according to the actual resilience of each port. The research provides new ideas and directions for investors to invest in port construction and has certain practical guiding significance for the increase of investors’ income and the sound development of the national economy.

Long-Term Change of Coastline Length along Selected Coastal Countries of Eurasia and African Continents

The acquisition of dynamic coastline change at fine spatial and temporal resolution is essential for enhancing sustainable coastal economic development and coastal environmental conservation. Port construction, land reclamation, urban development, and sediment deposition have resulted in extensive coastline change. In this study, the coastlines along the 56 coastal countries in 1990, 2000, 2010, 2015, and 2020 were delineated and classified into six categories using Landsat time–series images. Five relevant indices, i.e., the length, length ratio, length change rate, index of coastline utilization degree (ICUD), and fractal dimension (FD), were calculated to analyze and explore the spatiotemporal pattern of the coastlines. The results indicate that: (1) The overall length of the coastlines has increased from 3.45 × 105 km to 3.48 × 105 km in the past 30 years, with a net increase of nearly 3904 km. Between 1990 and 2020, the length of the artificial coastline increased by about 13,835 km (4.9~8.8%), while the length of the natural coastline decreased by 9932 km (95.1~91.2%). The increase in artificial coastline is concentrated in Southeast Asia and South Asia. (2) The coastline fractal dimensions (FDs) of countries and continents show that the average FD values of countries in South Asia (1.3~1.4) and Southeast Asia (1.2~1.3) were higher than other countries in the study regions, meaning that the coastlines in South Asia and Southeast Asia are more complex and curved. (3) The value of the ICUD index increased consistently between 1990 and 2015 (177.7~186.6) but decreased sharply between 2015 and 2020 (186.6~162.4), implying that the impact of human activities on the coastline continued to increase until 2015 and began to decrease after 2015. Our study examined the changes in various types of coastlines, which could be significant for sustainable development and environmental protection in coastal areas.

Dynamic evolution of green total factor productivity growth of China’s coastal ports

ABSTRACT As an important part of the comprehensive transportation system, ports play an important role in economic development. In the context of the ‘3060 double carbon’ target, the high-quality development (HQD) of ports is receiving attention from many parties. The aim of this paper is to examine the dynamic evolution of HQD in China’s coastal ports from the perspective of green total factor productivity (GTFP). Firstly, the calculation standards of undesirable outputs are given, and integrated environmental dumping indicator is calculated by the combination weight calculation model based on game theory. Then, the super-efficiency DEA-GML (Data Envelopment Analysis-Data Envelopment Analysis-Global Malmquist-Luenberger) index model based on directional distance function (DDF) is used to measure the GTFP growth of ports. Furthermore, the dynamic evolution of GTFP growth of ports is explored using the kernel density estimation. The findings show that the GTFP growth of coastal ports has continued to improve during the examined period. However, there is the problem that port construction inputs cannot bring effective outputs, and there is a bifurcation that tends to stabilize within coastal ports. Finally, targeted policy implications are given to promote HQD of ports.

China’s Foreign Policy Shift in South Asia vis-à-vis Belt and Road Initiative

China’s foreign policy shift in South Asia has been largely driven by its Belt and Road Initiative (BRI), which seeks to enhance connectivity and economic cooperation across Asia and beyond. South Asia, with its strategic location and growing economic potential, has emerged as a key area of focus for China under the B RI. In this context, China has pursued a multi-pronged approach, which includes infrastructure development, economic cooperation, and strategic partnerships with key countries in the region. One of the key components of China’s foreign policy shift in South Asia has been its emphasis on infrastructure development. China has invested heavily in the construction of roads, railways, ports, and other infrastructure projects in the region, with the aim of improving connectivity and facilitating trade and commerce. These investments have been largely made through the BRI framework, which has provided China with a platform to promote its economic and strategic interests in the region. China has also sought to deepen economic cooperation with South Asian countries through the BRI. This has involved the signing of a number of bilateral and regional trade agreements, as well as the establishment of special economic zones and industrial parks. Through these initiatives, China has sought to increase its access to South Asian markets and promote the growth of its own economy. In addition to these economic initiatives, China has also sought to establish strategic partnerships with key countries in the region. This has involved strengthening its ties with countries such as Pakistan, Sri Lanka, and Bangladesh, which have strategic significance due to their location and their potential to provide China with access to key markets and resources. These partnerships have also involved cooperation in areas such as defense and security, with China seeking to establish a greater presence in the Indian Ocean region.

Present And Future Indonesian Maritime Leadership

After decades of being behind the back, the words sea and maritime have begun to be echoed again after President Joko Widodo's speech at the 9th East Asia Summit, in Nay Pyi Taw, Myanmar, 13 November 2014 which wished to make Indonesia a World Maritime Axis (PMD). In order to make PMD successful, the President and Cabinet Ministers lowered various policies and government action programs starting from the national level down to a lower and more realistic level. Like the sinking of ships carrying out IUU fishing carried out by the Ministry of Maritime Affairs and Fisheries. PMD policy implementation invites a reactive attitude from countries inside and outside the Southeast Asian region. and there are big countries outside the region that seem not to support or oppose it. In the second period maritime issues are no longer visible, now it has been 8 years since the leadership of President Joko Widodo continues. The vision of making Indonesia the world's maritime axis seems to be swallowed up by time. The results of the execution of programs such as the construction of international standard ports and maritime highways are not yet clear. Indonesia still has a lot to improve itself. Even though development activities are currently focused on post-covid economic recovery and all anticipation of a new wave. The World Maritime Axis is no longer a major issue. However, at least the PMD program triggers the community and other elements of the nation to develop a sense of love and ownership of the sea.

Research on the Talent Training Mode of Business English Based on University-Industry Collaboration

With the in-depth implementation of China’s free trade port construction, the demand for business English professionals is growing. However, graduates who only have language skills cannot meet the needs of enterprises, and the current business English talent training model needs to be updated. Meanwhile, there are some problems such as the outdated teaching content of business English and the weak teaching staff. This paper puts forward the discussion of the university- industry cooperation mode. First, it clarifies the professional orientation and enterprises’ needs. College teachers and enterprise tutors cooperate deeply, and then improve the teaching content, build a curriculum system integrating theory and practice. It puts forward four cooperation modules, which are research and innovation, technology transfer, providing expert consulting services, and product commercialization.

Analysis of the Interconnected Development Potential of the Oil, Gas and Transport Industries in the Russian Arctic

This article describes the hydrocarbon reserves in the oil and gas provinces of Russia’s Arctic territory, as well as specific features of the region’s raw hydrocarbon potential. It has been noted that the implementation of Arctic hydrocarbon-associated projects requires that a unified transport and logistics system be created, with the Northern Sea Route being the basis. The factors affecting the volume of cargo transportation along the Arctic routes are presented. It has been established that the hydrocarbon extraction and liquefied natural gas production in the Russian Arctic zone is the most important factor in the formation of cargo flows along the Northern Sea Route. The most significant oil and gas projects that comprise the bulk of freight traffic flow along the Arctic transportation corridors have been reviewed. The ports, as the main element of the Arctic transport system, are described in terms of their state and infrastructure. It has been indicated that the construction, modernization, and operation of the Arctic ports are closely related to the creation of long-distance railway corridors, and the construction of new railway lines leading to the Arctic Basin ports can serve as a reliable basis for the growth of the Northern Sea Route’s cargo potential. A conclusion has been drawn about the special significance of the Murmansk region for the formation of the Arctic transport system.

Policy-driven or market-driven? A new perspective on the development of China’s cruise industry

The past 15 years have witnessed the rapid development of China’s cruise industry from scratch and the formation of a policy system in the cruise industry, reflecting the shift of the Chinese government’s attitude towards the cruise industry from wait-and-see, recognition and encouragement to active support. The paper conducts a statistical analysis of 128 policies related to the cruise industry issued by China’s administrative departments at all levels. It is found that the release of policies synchronizes with the development of the cruise industry, with each one providing feedback to the other. The policies do not exhibit a time lag with respect to their effects. The evolution of policy types from macro-level guidance to concrete operation is rapid, with the policy structure gradually improving. In line with current characteristics of the development of China’s cruise industry, the themes of the policies concentrate on five areas: cruise tourism services and products, port construction and development, cruise industry chain expansion, cruise industry environment and cruise industry management. However, there is still a lack of adequate policies to support and guide the industrial upgrading of cruise operation and cruise construction and its green and low-carbon development. In addition, the paper points out the main directions of future policy formulation.

Organization of river-sea container transportation in the Yangtze River: Processes and mechanisms

Port systems' regionalization is driven by inland port construction and shipping logistics. Among them, riverports are unique inland ports that are connected by seaport systems and contribute to a river-sea container transportation (RSCT) organization. Through a case study of the Yangtze River, this study conceptualizes RSCT based on the “spatial-network” perspective, and the driving forces pertaining to globalization, informatization, marketization, and greenization are examined. Further, we explore the trajectory of port regionalization and supply chain terminalization between coastal and inland areas, and analyze the multiscale mechanism of transportation and service development among ports considering spatial effects. The results suggest that a significant temporal gradient exists in port regionalization between the coast and inland regions. Logistics supply chain terminalization, a component of regionalization, forms and develops only during the growing stage of regionalization. Currently, the Yangtze River port system is regionalizing and being terminalized, contributing to spatial variation between the size and capacity of different types of seaports and inland ports in providing container transportation and logistics-derived services. The framework is validated by a quantitative empirical analysis based on container barge route data and shipping service enterprise data, thus confirming the evolution process from coastal concentration to inland decentralization for both. The study findings indicate that transportation's decentralization is more significant at the macro level, and that the service cannot narrow the gap between coastal and inland areas significantly with the current development of port systems in the Yangtze River. The interaction between “spatial” and “network” has only improved in seaports, and the nexus of the transportation and logistics supply chains has not yet been formed at the macro level. This study contributes to the literature on port regionalization from the spatial network perspective and provides insight into the relationship between seaports and inland ports in a complex port system.

An Empirical Study on the Training of Nursing Major English Talents in Vocational Universities in Hainan

In the context of the construction of Hainan Free Trade Port, the development of medical and health tourism has policy advantages and development opportunities, and the development prospect is promising. Hainan's medical and health industry is increasingly in line with international standards, and the demand for nursing talents is increasing year by year. However, the human resources for medical and health tourism are insufficient. The demand for nursing talents with English application ability and familiar with international languages is also increasing rapidly. Based on the empirical analysis and research on the statistical survey data of nursing enrollment, English curriculum, and the status quo of teacher training in a vocational college in Hainan Province in recent four years, this paper evaluates and analyzes the status quo of nursing talent training in Hainan's vocational universities, and puts forward suggestions on how to improve and cultivate medical and health nursing personnel who meet the needs of the construction of a free trade port, At the same time, it puts forward a more targeted reform direction of specialized English teaching for vocational colleges in Hainan Province.

Research on the causes of juvenile delinquency in Hainan province

Hainan, as an island province far away from the mainland, has many differences with the mainland in history, economy and culture. Therefore, there are many differences in the family, school and social environment of minors in Hainan compared with those in mainland China. These differences are also reflected in the juvenile delinquency in Hainan. Now Hainan Province is in the high-speed construction of free trade port, how to prevent juvenile delinquency is particularly important. Based on the quantitative analysis of the data of each city and county in Hainan Province from 2010 to 2019, this paper obtains the influence degree of the specific factors affecting juvenile delinquency in Hainan Province, among which the divorce rate is the highest and the disposable annual income of the family is the lowest. At the same time, we put forward corresponding suggestions for the three subjects of school, government and family.

The Anthropogenic Affect—Humans and Geology: An Example from Tel Dor, Israel

Geology usually deals with rocks formed long ago, which are static and stable over the span of human lifetime. This study aims to analyze anthropogenic influence on the formation of geological features in the southeastern Mediterranean. Tel Dor, along Israel’s northern coast, was chosen due to the continuous presence of humans in the area for over 4000 years and the protective environment of its natural bays that preserve geomorphological changes. This allows for the examination of whether and how humans affect their (geological) environment. Three rocky platforms were chosen in the shallow waters of the South Bay adjacent to the Tel, and four cores were extracted. Results show the extent of the direct and indirect anthropological influences on the landscape. The presence of building stones consisting of dolomite, which is not found along the Carmel coast, is an example of direct influence (importation). The evolution of a biological and non-biological reef upon the sturdy base of the port constructions is an indirect influence. The formation of a non-biological reef upon an archaeological feature is a unique process. It would not have consolidated without the presence of anthropogenic activity. This study shows how human interference in the coastal area can trigger a chain reaction of geological processes lasting more than 2000 years.

EVALUATION OF LONG-TERM OBSERVATION OF OCEANIC CURRENTS IN THE COASTAL AREAS OF THE OMAN SEA (MOKRAN COAST) USING COASTAL HIGH- FREQUENCY RADARS

Abstract. Ocean currents are of interest to all who deal with marine affairs. Since they can be predicted, as a result, they are essential as renewable energy for us. We can use it in many applications like navigation, generating electricity, and port constructions. So, studying them and discovering the factors that create and influence them is significant. Using the instrumentation that we can use continuously and do not have many problems is preferred. Therefore, using new technologies instead of old traditional methods is crucial. In this study, we discuss ocean currents in the Oman Sea, suggest high-frequency radars (HFR) as new technology, and represent its advantages instead of ADCP. We use Mike 21 to get tidal current constituents and compare them with other data. The results show that values of two components, Mm and MSF, are more respective to astronomical-driven currents. Therefore, the amount of tidal current on the coast of Mokran is low, and other factors cause the current, which short-term observations in this region cannot be achieved. Thus, we need data in a more extended period to find present generating forces and predict them. HFR can be an efficient and valuable tool in such areas.

Study on the Interaction between Green Competitiveness of Coastal Ports and Hinterland Economy

Accelerating the construction of green ports and promoting the green transformation of the economy and society are important trends in port and regional development today. This research explores the interaction between the green competitiveness of coastal ports and the hinterland economy from 2007 to 2019 by taking the 10 largest coastal ports in China as the research object and combining the Super-SBM Model with the panel data model. The results show that the green competitiveness of coastal ports is fluctuating, and the green competitiveness of Qingdao and Shanghai ports is stronger in the production frontier surface. Compared with the size of ports, the level of port technology is an important factor to improve the green competitiveness of ports. In terms of interaction, the total economic volume of the hinterland, the proportion of the added value of the tertiary industry, and the waterway transportation between the port and the hinterland have a significant positive impact on the green competitiveness of the port, and the improvement of the green competitiveness of the port and the waterway transportation between the port and the hinterland effectively drive the economic development of the hinterland. This study provides an important basis for the rational use of the port–hinterland interaction and promotes the coordinated and healthy development of both.

Construction of the Hainan Free Trade Port from the perspective of regional cultural development

This study summarizes the internal relationship and mechanism of industrialization, business culture, and higher education that affect the development of modern industrial and commercial culture, and consequently, the construction of free trade ports in Hainan. The cases of Hong Kong, Singapore, and Dubai free trade ports were considered as references. Based on immigration, naturalization, and education in Hainan’s history, Hainan’s cultural base map, which influences the construction of modern industrial and commercial culture, was proposed to be formed by splicing and overlapping of the free, guarding, farming-reading, farming-marine, and immigrant cultures. The development course of Hainan in the past 30 years indicated that although Hainan has always been at the forefront and highland of reform and opening up, it is still relatively backward despite the implementation of long-term policies; moreover, its development performance is not ideal. The existing problems and factors related to the present ideology mainly include the following: 1) The pursuit of “making quick money” has led to the ups and downs of Hainan’s development. 2) Lack of innovation hinders functional improvement leading to poor sustainability. 3) The course of modern industrial civilization based on a cultural base map is short. 4) Although bottom-up industrialization plays a key role in the formation of modern industrial civilization, it is not followed by Hainan. Furthermore, the cultural development path of Hainan Free Trade Port construction should 1) strongly promote industrialization by overcoming the shortcomings of industrial development, 2) deepen the reform of the agricultural reclamation system, improve the business environment, and cultivate a healthy modern industrial and commercial culture, 3) standardize the tourism market, and build the most advanced tourism industry culture, 4) improve the basic education level and develop excellent higher education opportunities, 5) enhance the diversity of human resources structure, and 6) revitalize literature and art, and showcase and develop Hainan’s fine culture. Overall, the construction of the Hainan Free Trade Port requires long-term upgrading and development. It is necessary to continue cultural construction, adapt to the requirements of the highest level of openness and realize the healthy development of the Hainan Free Trade Port.
