High-speed trains in Japan in the years 2002–2020

High-speed trains are the most modern and advanced technology for moving passengers in land transport. Their main advantage is that they achieve high speeds, usually from over 200 to 300 km/h, which significantly shortens the travel time in relation to the time needed to cover the same distance by conventional trains. The article presents the development of high-speed rail in Japan, an island country located within the ring of fire of the Pacific. The analysis of the technical condition and the stages of historical development of high-speed railways were preceded by an assessment of the economy and transport as well as a study of transport intensity. The summary of the article includes the effects and benefits of using high-speed rail, as well as methods of financing and plans for further development.

Characterization of Micro-seismic Activity in Northern Cyprus Using Complexity and Corner Frequency Methods

Cyprus is an island country located in the eastern Mediterranean, to the south of Türkiye and the western of Syria and Lebanon, and is a popular tourist destination. Due to being surrounded by seas on all four sides, meticulous planning of rescue, assistance, and evacuation plans is necessary in the face of disasters such as earthquakes and tsunamis. Tectonically, the southern part of the island is controlled by the Cyprus Arc, while the northern part is dominated by the Kyrenia Range. The demand for raw materials for construction and industry is met through controlled quarry blasting operations carried out by open-pit quarry companies in the districts of Kyrenia and Nicosia. As a result, both natural and artificial seismic events occur in the region, and these quakes are documented in seismic catalogs by seismology centers. However, due to the low energy content of micro-seismic events and the inadequacy of seismic stations on the island, the source types of these seismic events can be misidentified in the catalogs. In this context, the study focuses on 122 seismic events with magnitudes between 0.9≤Ml≤2.7 that occurred in Northern Cyprus during the January 2018 - December 2021 period (4 years). The seismic events recorded by the station LFK, operated by Boğaziçi University Kandilli Observatory and Earthquake Research Institute Regional Earthquake-Tsunami Monitoring Center (KOERI-RETMC), were classified using Linear and Quadratic Discriminant Functions based on complexity and corner frequency methods. According to the results obtained, 10 of the 122 seismic events were identified as natural, and 96 were determined to be artificial, resulting in a general success rate of 86.89%. However, classification results for 16 seismic events were inconclusive with the methods used. As a result, more detailed secondary analyses should be conducted to accurately determine the source types of micro-seismic events, and the seismic catalogs should be updated accordingly.

Measuring what matters: Context-specific indicators for assessing immunisation performance in Pacific Island Countries and Areas.

Increasing countries' access to data can improve immunisation coverage through evidence-based decision-making. However, data collection and reporting is resource-intensive, so needs to be pragmatic, especially in low-and-middle-income countries. We aimed to identify which indicators are most important for measuring, and improving, national immunisation performance in Pacific Island Countries (PICs). We conducted an expert elicitation study, asking 13 experts involved in delivering immunisation programs, decision-makers, health information specialists, and global development partners across PICs to rate 41 indicators based on their knowledge of the feasibility and relevance of each indicator. We also asked experts their preferences for indicators to be retained or removed from a list of indicators for PICs. Experts participated in two rating rounds, with a discussion on the reasons for ratings before the second round. We calculated mean scores for feasibility and relevance, and ranked indicators based on experts' preferences and mean scores. We used framework analysis to identify reasons for selecting indicators. Experts agreed that certain indicators were essential to measure (e.g. data use in program planning and measles vaccination coverage), but preferences varied for most indicators. Preferences to include indicators in a set of indicators for PICs moderately correlated with scores for relevance (r = 0.68) and feasibility (r = 0.56). In discussions, experts highlighted usefulness for decision-making and ease of data collection, reporting and interpretation as the main reasons driving indicator selection. Country-specific factors such as health system factors, roles and influence of various immunisation actors, and macro-level factors (namely population size, distribution and mobility) affected relevance and feasibility, leading us to conclude that a single set of indicators for all PICs is inappropriate. Rather than having a strict set of indicators that all countries must measure and report against, performance indicators should be flexible, country-specific, and selected in consultation with immunisation actors who collect and use the data.

"I've yet to meet anyone who's not keen for simulation" - a qualitative study of simulation-based education in the Pacific Islands.

Simulation-based education (SBE) has been increasingly used to train healthcare workers in low-resource settings and has been endorsed by the World Health Organization (WHO). Consideration of the educational and cultural context is important to maximize the effectiveness of SBE. Despite its demonstrable benefits, there have been no studies of the general approach in the Pacific Islands. This study aimed to determine the factors that influence the uptake and success of SBE in the Pacific Islands. In this qualitative study, participants were recruited via professional networks to contribute to focus groups. Questions focused on participants' previous experiences and perspectives on SBE. Data were manually transcribed before thematic analysis. The reporting of the research was guided by the Standards for Reporting Qualitative Research (SRQR). Human Research Ethics Committee approval was obtained. Two focus groups were conducted with 16 participants from six Pacific Island countries. Six themes and 15 subthemes were conceptualized from the data. Uptake of SBE is challenged by resource availability, clinical workloads and geographic remoteness. However, locally-driven solutions and positive attitudes towards SBE facilitate its success. This study reveals the complexity of factors affecting the uptake and success of SBE in the Pacific Islands. These findings can serve to optimize the impact of existing and future SBE programmes and may be considered by educators prior to programme implementation.

How does energy intensity impact economic growth for the case of a small island country

AbstractIn this article, we explore the relationships between economic growth and energy intensity in Bahrain, and we analyse how energy intensity, population, and other macroeconomic variables are associated with each in the short and long run. In the empirical section we use data span from 1980 to 2019 and we perform a vector error correction model and cointegration technique to detect causality between the variables used in the model. The main findings of this article show that economic growth, population and FDI increased energy intensity in Bahrain in the short run. Therefore, an urgent need to be embedded in the sustainable energy action plan to limit the harmful effects of economic activity on the environmental quality in Bahrain and to ensure environmental sustainability.

Coastal fisheries and community-based support systems in post disaster contexts

Pacific Island Countries and Territories are highly exposed to natural disasters, intensified by increases in frequency and force of extreme weather events. Pacific societies, like in Vanuatu, have been shaped in many ways by such natural disasters; reflected in customary practices and social fabric of rural coastal communities. When a natural disaster occurs, government attention justifiably focuses on channelling and coordinating international humanitarian aid to fill gaps in capacity and resourcing national recovery efforts. However, central to disaster recovery, particularly in the immediate aftermath of disruption, are the ways that local people support each other (within and between communities). Disconnects between national and local recovery efforts are common and stand to inhibit effective responses. This study aims to understand horizontal, self-organised community-to-community support systems and communities’ post-disaster engagement with external aid. It draws from two different datasets: i) the observations collected through the emergency relief work led by the National Disaster Management Office in Vanuatu shortly after the 2023 twin tropical cyclones Judy and Kevin hit the country, as well as ii) the loss and damage survey led by the Vanuatu Fisheries Department to estimate the level of damage these cyclones caused in various regions of Vanuatu. Through this process, we highlight the social systems that enable community-to-community support, as well as potential opportunities for external-aid to support communities in a more efficient manner. Results reveal that community-to-community support is critical in the first weeks post-disaster. Recognizing the roles that different support networks play at different stages of disaster response is critical not only to improving people's and institutions' ability to bounce back from particular disruptions, but also in broader efforts to strengthen community resilience in the face of climate change.

Climate justice and Pacific Island countries – a case study on grassroots advocacy

ABSTRACT Many Commonwealth member states face the brunt of the climate crisis. In the Pacific Island states and the wider Pacific region, the frequency of severe weather events has increased. For instance, in 2023 the island of Vanuatu was impacted by cyclones Judy and Kevin in March and afterwards by cyclone Lola. According to Vanuatu officials, more than 10,000 homes were destroyed and the storms caused massive destruction to Vanuatu’s infrastructure and economy. Facing the likelihood that the global temperatures will reach or surpass the 1.5 degrees Celsius target between 2021 and 2040, a grassroots student movement was launched at the University of the South Pacific (USP) based on Emalus Campus, Vanuatu, which ended with a United Nations General Assembly resolution on climate justice and Pacific Island states. Even so, the situation remains alarming for many Commonwealth Small Island Developing States (SIDS) in the Pacific and there are important questions as to how these states will adapt to and mitigate climate change and also address the climate justice issues they face. This article provides a case study on climate justice and Commonwealth member states and looks at measures currently being considered or implemented by political leaders and other stakeholders.

Mercury from Icelandic geothermal activity: High enrichments in soils, low emissions to the atmosphere

Geothermal activity is a natural source of mercury (Hg) to surface environments, but its contributions as part of the larger geogenic flux to the global Hg budget are poorly understood, in part due to large geographic gaps in emissions data where no measurements have been made. In this study we report the results of a field campaign over 2021 and 2022 on the highly active volcanic island country of Iceland. Six geothermal sites across the country were investigated for soil gaseous elemental mercury (GEM) and total Hg (THg) concentrations through a series of measurements made across the diffuse degassing surface. At 10 cm depth, soil GEM concentrations were often hundreds and in some cases thousands of times higher than ambient surface air concentrations. Geothermal soils were also highly enriched in THg due to the sorption of hydrothermal Hg on the characteristically fine, thermally-altered clays and silts. Soil “hotspots” displayed THg concentrations exceeding 100 µg g−1 comparable to levels in areas heavily contaminated by anthropogenic activity and in Hg-rich mineral soils. Strong correlations were observed between soil GEM, THg and soil temperature, and intensive measurements made at small spatial scales (∼1 m2) demonstrated the representativeness of individual sampling points. By adapting an active sampling gradient method for determining soil–air gas fluxes, we estimate an Icelandic geothermal GEM flux of 1.8 kg a−1 and a total Icelandic GEM flux, including non-geothermal areas, of ∼18 kg a−1. This work shows that Icelandic geothermal activity can generate high GEM and THg concentrations in the local soil environment, but its contribution to global Hg cycling appears to be minor.

Leading from the Frontline: A History of Pacific Climate Diplomacy

ABSTRACT Pacific Island states have, for decades, considered climate change a threat to their security. In 1991, island leaders declared global warming and sea level rise as serious environmental threats, and that their ‘cultural, economic and physical survival’ was at risk. Pacific Island countries have since played a disproportionate role in United Nations climate negotiations, working as a diplomatic bloc to shape new rules and to drive multilateral cooperation to reduce emissions. Pacific Island states have also sought greater recognition of climate change as a security threat. This article considers the history of Pacific climate diplomacy. It explains how Pacific Island countries have played a key role in the global response to the climate crisis and outlines the history of regional climate politics in the Pacific Islands Forum. We also focus on recurring tensions between Pacific Island states and Australia with regard to ambition to tackle climate change.

A practical stakeholder-focused approach for assessing the biosecurity system in Pacific Island countries

ABSTRACT Aims: To develop a structured process for a transparent, efficient, high-level review of a low-resource biosecurity system (limited by physical infrastructure, financial, and human resources), in order to identify and prioritise key areas for future focus which could then lead to interventions, tailored by country, to improve the system. A key requirement was that the approach developed was culturally sensitive and respectful to Pasifika people within the country. Methods: Animal health and biosecurity systems need to be urgently strengthened by Pacific Island countries and territories (PICTs) if they are to respond to current and future threats. Understanding where additional resources should be allocated to maximise benefit and ensuring buy-in from PICT stakeholders are critical for uptake of any recommendations made. However, there is little available literature on reviewing biosecurity systems, particularly where there is a need for efficiency, simplicity, and cultural sensitivity. A framework was developed through initial in-person consultation between four New Zealand experts who had experience working in international animal health development and support programmes. This was followed by input from informal discussions with selected heads of agriculture in PICTs and included their experiences with previous system reviews, as well as general advice from experts in Pasifika culture. Foundational objectives included simplicity, local inclusivity, and a structured approach, which could be undertaken over a relatively short period of time. A rapid evidence assessment methodology was used to search the available literature (published and grey, search terms biosecurity, system, Pacific, animal, framework, and review used in AND/OR combinations), to establish an evidence base for other methods of biosecurity system review. The developed framework for review of biosecurity systems in low-resource PICTs was based on elements from expert elicitation frameworks, the SurF surveillance evaluation framework and the Performance of Veterinary Services tool from The World Organisation for Animal Health. Results: The developed framework involved bringing stakeholders together in a workshop environment and comprised up to 10 steps including mapping the PICT biosecurity system and exploring attributes of component activities. Understanding the system at a high level enables stakeholders to make informed recommendations on improvements to address future needs. Using the Delphi method, recommendations were then prioritised by stakeholders. Conclusions and clinical relevance: A distinctive difference flowing from the use of the needs analysis described in this process was the empowerment of PICT stakeholders to determine their own needs and priorities, rather than have these developed by external parties.

Noncommunicable disease risk behaviors and protective factors among children in Samoa: Retrospective trend analysis of global school-based health surveys in 2011 and 2017.

Pacific Island countries experience a high prevalence of noncommunicable diseases (NCDs), which may be prevented by reducing risk behaviors and strengthening protective factors in childhood and adolescence. To better inform preventative interventions, our objective was to use publicly available data from the Global School-based Student Health Survey (GSHS), to provide cross-sectional and trend estimates for the prevalence of NCD risk and protective factors among school-aged children in 2011 and 2017 in Samoa. Two waves of cross-sectional data included 4,373 children (51.98% female), with a median age of 15 years, who were mainly in school years 9-10 in Samoa. Retrospective analyses were adjusted for the GSHS multistage stratified cluster sample design. Weighted prevalences of overweight/obesity, dietary behaviors, physical activity, and sedentary behavior, oral and hand hygiene, emotional and mental health, and community protective factors were reported by study year. Logistic regressions were fitted to assess differences in the prevalence of risk and protective factors, adjusted for age group, sex, and school year. In 2011 and 2017, the prevalence of overweight/obesity remained consistently high in females (59.12% and 64.29%, p = 0.428) and increased from 44.21% to 53.65% in males (p = 0.039). Time spent sitting for long periods, smoking cigarettes, using other tobacco products, and drinking alcohol were lower in 2017 compared to 2011 (all p<0.05). Many children reported experiencing bullying (33.27% for females and 59.30% for males in 2017), while physical fighting was common among males (73.72% in 2011 and 57.28% in 2017). The high prevalence of obesity and related NCD risk factors require urgent public health action in Samoa. Alongside the continued reduction of tobacco and alcohol use, emotional and mental wellness should be prioritized in interventions and programs to promote healthy behaviors and lifestyle changes starting in childhood.

The United States as a ‘Pacific Nation’: Imaginary, Performance, and Spatialisation

ABSTRACT In 2012, then United States (US) Secretary of State Hilary Clinton attended the leaders’ meeting of the Pacific Islands Forum, the region’s pre-eminent politics and security-focused multilateral institution. At the meeting, Clinton remarked that: ‘I have said that the 21st century will be America’s Pacific century, with an emphasis on Pacific’, as the US is ‘a Pacific nation’. In this article, we analyse how, in the decade since, US government discourse has continued to narrate a social imaginary of the US as a ‘Pacific nation’ and to attempt to bring that imaginary into being through diplomatic performances and government policy. This has been driven by strategic concerns about the increasing activism of China in the Pacific Islands region and has sought to justify the US’s role, build its relationships, and exercise its power in the region. We argue that when the US is front stage and conscious of being observed, it narrates an imaginary of itself as a Pacific nation and performs that imaginary through its diplomatic performances and policy announcements. But the US’s back stage behaviour, including the non-implementation of policies and the spatialisation of the Pacific Islands region through efforts to discipline Pacific Island countries, build boundaries that exclude China, and emplace the US military presence, reveals its true intentions.

Spatial and Temporal Variability of Ocean Thermal Energy Resource of the Pacific Islands

A lack of natural resources drives the oil dependency in Pacific Island Countries and Territories (PICTs), hampering energy security and imposing high electricity tariffs in the region. Nevertheless, the Western Equatorial Pacific is known for its large Sea Surface Temperature (SST) and deep-sea water (DSW) temperature difference favorable for harvesting thermal energy. In this study, we selected 18 PICTs in the western Equatorial Pacific to estimate Annual Energy Production (AEP) for a 1 MW class Ocean Thermal Energy Conversion (OTEC) plant. We combined the DSW temperature from the mean in situ Argo profiles and 1 km resolution satellite SST data to estimate the thermal energy resource resolving the fine features of the island coastline. Furthermore, the twenty-year-long SST dataset was used to analyze the SST variability. The analysis showed that Equatorial islands and Southern islands have the highest inter-annual variability due to El Nino Southern Oscillation (ENSO). The power density varied from 0.26 to 0.32 W/m2 among the islands, with the lowest values found for the southernmost islands near the South Equatorial Countercurrent. Islands within the South Equatorial Current, Equatorial Undercurrent, and North Equatorial Countercurrent showed the highest values for both power density and gross power. Considering a 1 MW class OTEC plant, Annual Energy Production (AEP) in 2022 varied from 7 GWh to 8 GWh, with relatively low variability among islands near the Equator and in low latitudes. Considering the three variables, AEP, SST variability, and distance from the shore, Nauru is a potential candidate for OTEC, with a net power of 1.14 MW within 1 km from the shore.

The influence of food tax on island places

Noncommunicable diseases (NCDs) are the primary cause of premature mortality in Pacific Island Countries and Territories (PICTs), as well as in numerous other jurisdictions worldwide. The Pacific region has declared an NCD crisis and has recommended the implementation of food taxation policies to address the dietary risk factors associated with these diseases. However, the progress in this regard remains uncertain.The review focused on food taxation policies, including excise taxes and tariffs, that were implemented between 2000 and 2020 in 22 PICTs. The key characteristics of these policies were examined. The search for relevant information was conducted using databases, government legal repositories, and broad-based search engines. The identified documents for screening included legislation, reports, academic literature, news articles, and grey literature. Additionally, key informants from each PICT were contacted to gather further data and validate the findings. The results were analyzed through narrative synthesis. Out of the 22 PICTs included in the study, 14 had implemented food taxation policies, and 5 had introduced excise taxes. Processed foods, sugar, and salt were the primary targets of these excise taxes. A total of 84 changes in food taxation policies were identified across all food groups. Among these changes, a total of 279 taxes were identified based on food groups, with 85% being tariffs and 15% being excise taxes. The individual tax rates varied significantly. The most common tax design was ad valorem, followed by volumetric.

Japanese Consciousness of Narrowing from the Perspective of Architecture

One of the characteristics of Japanese culture is the “consciousness of narrowing”. Sei Shonagon once wrote in “The Pillow Book” that “no matter what, small things are exquisite.” The Japanese people's awareness of the beauty of smallness is widespread and is reflected in every aspect, and it can be said that “smallness” exists everywhere in Japan. Japan is a small island country surrounded by the sea on all sides, in such a geographical environment, the Japanese people have developed a “consciousness of narrowing”. This “consciousness of narrowing” has had a profound impact on many aspects of Japanese society, and has led to the formation of a unique Japanese culture. Culturally, the Japanese art of flower arrangement and architecture also pursues subtlety and delicacy in form and structure, and favors a small and exquisite style in its aesthetic sense. Throughout the history of mankind, no matter what era, architecture has always served to protect mankind and avoid danger. Even though the style of architecture has changed with the change of time, the cultural connotation embodied in it is still preserved. Therefore, this thesis analyzes the causes and effects of the “consciousness of narrowing” on Japanese society to further understand the unique culture of the Japanese people. At the same time, by citing representative Japanese buildings and understanding the “consciousness of narrowing” embodied in them, it is hoped that the national character and aesthetic sense of the Japanese people can be further understood, and that Sino-Japanese cultural exchanges can be promoted. At the end of this thesis, we will briefly compare the differences between Japanese traditional culture and Chinese traditional culture represented by “consciousness of narrowing”, hoping to further understand Japanese culture on this basis, and to help promote cultural exchanges between China and Japan.

Explaining sender–receiver gaps in signalling: Australia’s ‘Pacific Step-up’ and Solomon Islands’ multi-alignment

Amid growing strategic competition, regional powers have intensified their engagement with Pacific Island Countries. This article examines Australia’s ‘Pacific Step-up’, a signature foreign policy initiative of the Scott Morrison government (2018–2022), from a signalling perspective. Through the Step-up, Australia sought to affirm its resolve to be partner of choice for Pacific Island Countries. This was not cheap talk but led Canberra to invest substantially in its ties with the region. Despite this and significant prior Australian engagement leading to a bilateral security pact, Solomon Islands’ government signed an additional security agreement with China in 2022. How can we explain this sender–receiver gap? I argue that close attention to the agency of domestic actors on the receiver side and the context in which such agency occurs – in this case, an extended history of insecurity in the Pacific country – provides us with analytical leverage when examining concrete instances of signalling.

Infrastructure and Human Capital Investment in Madagascar

Madagascar, an island country that separated from mainland Africa 80 million years ago, has inherent advantages that potentially allow it to develop a tourism industry that could lead the country out of poverty. However, due to reasons such as political instability or difficulty during implementation, Madagascar has yet to improve its economic conditions. This work puts forth an implementable set of actions, mainly composed of investment in infrastructure and human capital around Andasibe-Mantadia National Park, that may improve Madagascars current economic situation. Although many difficulties during implementation can be predicted, it is believed that Madagascars unique biodiversity, especially in Andasibe, could create significant changes. By comparing Andasibes situation with other East African countries national parks, this work attempts to prove how this investment may lead Madagascar to develop a strong tourism industry, leading the whole country to take another step towards industrialization.

Evaluating the temperature–mortality relationship over 16 years in Cyprus

ABSTRACT In many regions of the world, the relationship between ambient temperature and mortality is well-documented, but little is known about Cyprus, a Mediterranean island country where climate change is progressing faster than the global average. We Examined the association between daily ambient temperature and all-cause mortality risk in Cyprus. We conducted a time-series analysis with quasipoisson distribution and distributed lag non-linear models to investigate the association between temperature and all-cause mortality from 1 January 2004 to 31 December 2019 in five districts in Cyprus. We then performed a meta-analysis to estimate the overall temperature-mortality dose-response relationship in Cyprus. Excess mortality was computed to determine the public health burden caused by extreme temperatures. We did not find evidence of heterogeneity between the five districts (p = 0.47). The pooled results show that for cold effects, comparing the 1st, 2.5th, and 5th percentiles to the optimal temperature (temperature associated with least mortality, 25 ℃), the overall relative risks of mortality were 1.55 (95% CI: 1.32, 1.82), 1.41 (95% CI: 1.21, 1.64), and 1.32 (95% CI: 1.15, 1.52), respectively. For heat effects, the overall relative risks of mortality at the 95th, 97.5th and 99th percentiles were 1.10 (95% CI: 1.04, 1.16), 1.17 (95% CI: 1.07, 1.29), and 1.29 (95% CI: 1.11, 1.5), respectively. The excess mortality attributable to cold days accounted for 8.0 deaths (95% empirical CI: 4.5–10.8) for every 100 deaths, while the excess mortality attributable to heat days accounted for 1.3 deaths (95% empirical CI: 0.7–1.7) for every 100 deaths. The results prompt additional research into environmental risk prevention in this under-studied hot and dry region that could experience disproportionate climate change related exposures. Implications: The quantification of excess mortality attributable to temperature extremes shows an urgent need for targeted public health interventions and climate adaptation strategies in Cyprus and similar regions facing rapid climate change. Future steps should look into subpopulation sensitivity, coping strategies, and adaptive interventions to reduce potential future risks.
