Transient climate sensitivity relates total climate forcings from anthropogenic and other sources to surface temperature. Global transient climate sensitivity is well studied, as are the related concepts of equilibrium climate sensitivity (ECS) and transient climate response (TCR), but spatially disaggregated local climate sensitivity (LCS) is less so. An energy balance model (EBM) and an easily implemented semiparametric statistical approach are proposed to estimate LCS using the historical record and to assess its contribution to global transient climate sensitivity. Results suggest that areas dominated by ocean tend to import energy, they are relatively more sensitive to forcings, but they warm more slowly than areas dominated by land. Economic implications are discussed.

Ports and port cities play a pivotal role toward the sustainable development of coastal ecosystems. These ecosystems provide their natural capital by offering favorable locations for industry and accessibility to world markets. While port industrial activities have been reactive to pressure from stakeholders, in more recent years ports have adapted inclusive strategies and seek to align their strategic intentions with stakeholders. Around the world, port authorities are aligning their ambitions toward their contribution to the sustainable development goals (SDGs), such as the World Port Sustainability Program (WPSP) for port authorities and AIVP2030 for port cities. The aim of this chapter is to assess to what extent ports have contributed to the implementation of the SDGs. The analysis is based on a content analysis on a portfolio of 212 projects in which port authorities demonstrate leadership in sustainable development. The results indicate that the contributions of port and port city authorities are generally motivated to “do no harm.” Port authorities also have “do good” intentions for their ecosystems, which are mainly focused on reenforcing connections with communities and less to restore their impact on the biosphere. Furthermore, the findings show that linkages between WPSP projects with the SDGs are rather ambiguous. Directions are given toward a methodology for port authorities (PAs) to establish a stronger link between (monitoring) business strategies with the implementation of inclusive port development strategies to prevent using SDG reporting for greenwashing purposes.

This paper evaluates consumers' responses to claims regarding fruit sustainability. The authors compared the effects of this factor on consumers' moral satisfaction and purchase intention with respect to 12 sustainability claims.

A mixed-model experiment was conducted with seven fruits (i.e. guava, pineapple, red apple, green apple, red grape, green grape and avocado) to evaluate the effects of the 12 sustainability claims on purchase intention through moral satisfaction, relative to a control condition.

The results show that claims of supporting local farmers are those that move consumers the most. Claims regarding local farmers' production positively affect moral satisfaction and purchase intention.

This paper takes a consumer behavior approach to sustainability, enabling organizations to consider consumer behavior outcomes that could affect their strategic investments and commitment to social responsibility.

Food-related studies have not produced consistent results with respect to the relevance that sustainability claims have for consumers. This study differs from previous studies, as it focuses on fruit, a product that is important for social and environmental sustainability issues. This study demonstrates that, in the case of fruit, sustainability arguments are meaningful to young consumers through the mediating effect of moral satisfaction. Thus, the effect of claims is predicted by the meaning these arguments have for the consumer.

Este artículo evalúa las respuestas de los consumidores a los argumentos de sostenibilidad en una fruta. Se comparan los efectos de este factor en la satisfacción moral y la intención de compra de los consumidores con respecto a 12 argumentos de sostenibilidad.

Se realizó un experimento de modelo mixto con siete frutas (guayaba, piña, manzana roja, manzana verde, uva roja, uva verde y aguacate) para evaluar los efectos de los 12 argumentos de sostenibilidad sobre la intención de compra a través de la satisfacción moral, en relación con una condición de control.

Los resultados muestran que las afirmaciones de apoyo a los agricultores locales son las que más influyen en los consumidores. Las afirmaciones relativas a la producción de los agricultores locales afectan positivamente a la satisfacción moral y a la intención de compra.

Este trabajo adopta un enfoque de la sostenibilidad basado en el comportamiento del consumidor, lo que permite a las organizaciones considerar los resultados del comportamiento del consumidor que podrían afectar a sus inversiones estratégicas y a su compromiso con la responsabilidad social.

Los estudios relacionados con la alimentación no han arrojado resultados consistentes respecto a la relevancia que los argumentos de sostenibilidad tienen para los consumidores. Este estudio difiere de los anteriores, ya que se centra en la fruta, un producto importante por cuestiones de sostenibilidad social y medioambiental. Este estudio demuestra que, en el caso de la fruta, los argumentos de sostenibilidad son significativas para los consumidores jóvenes a través del efecto mediador de la satisfacción moral. Así, el efecto de los argumentos se predice por el significado que estos tienen para el consumidor.

Collective catering sector is increasingly offering alternative and more sustainable food propositions, but their success rests on their reception by guests and changes induced in individual behaviors. The authors investigate food-change determinants by examining the relationship between food behavior at staff restaurants and at home.

In an experiment over four days conducted in three staff restaurants, the authors monitored the behavioral changes and motivations of guests (n = 599) offered choices between standard and sustainable options for meat, fish, dairy products, fruit-based desserts and a vegetarian dish. The calculation of a “sustainable consumption score,” based on actual consumption at a restaurant by a subsample (n = 160) of guests gives an indication of interest for sustainable options.

Higher overall choices were observed for vegetarian dishes and for the sustainable meat options rather than for the sustainable fish and desserts options, thus suggesting contrasted perceptions of the sustainable alternatives. The results revealed two profiles of consumers with contrasting scores. The “lower receptive guests” had lower commitment to sustainable food at home and at staff restaurants, while the “higher receptive guests” found in the intervention meaningful propositions for pursuing their existing at-home commitment.

Long-term research would be required to verify whether repeated sustainable offers can break down deep-rooted choices and instill durable changes among consumers with lower commitment to sustainable food. This research contributes to the identification of some types of food that are more suitable for sustainable-oriented interventions.

Some food triggers are identified to further norm activation among the lower receptive profile of consumers.

By addressing continuities/discontinuities between at-home and at-restaurant consumption and mobilizing the “norm-activation” concept, the authors question the efficiency of sustainable food offers at work.

Competition among seaports is rapidly increasing due to various factors such as the global recession, resurgence of COVID-19, tight environmental regulations of IMO, sharp rise in ocean freight charges, increasing global uncertainties and growth in ship sizes. It is essential to have precise knowledge of shipping companies' port selection factors to secure the competitive advantage of seaports. This study aims to empirically analyze recent changes in the importance of port selection factors.

By employing a longitudinal study, this study conducted the t-test analysis. The first survey was conducted from January 2005 to April 2005. Then, the second survey was conducted in May 2021.

First, the importance of port facilities (berth length and the number of berths, shed and terminal areas, possession of adequate equipment and maximum berth size) increased significantly. Second, while ship and cargo safety were the critical port service factors in previous studies, speed, flexibility and reliability for handling cargo and berthing schedule were found to be crucial in this study. Third, the importance of ship arrival/departure frequency, route diversity and ship arrival/departure information systems increased when shipping companies selected the port.

This study has academic significance in that it reveals the changing importance of port selection factors in the 2020s and has taken the form of a longitudinal study on the importance of port selection factors from 2005 to 2021, moving beyond the cross-sectional approach. This study can provide valuable insights into and implications for port policymakers and managers when developing and formulating port policies and strategies.

This study aims to systematically review strategy making in the seaport context during a period of hyper uncertainty.

A systematic review using the context, intervention, method and outcome (CIMO) framework is conducted in the domains of strategy making and the port sector taking account of hyper uncertainty caused by Brexit.

Strategy making (under conditions of hyper uncertainty) is shown to evolve from both stakeholder/supply chain embedded relationships and from chief executive officer and extra organisational inputs. Through an iterative process of internal resourcing, stakeholder engagement strategy development can be seen to impact five key outcomes of an emerging strategy making under hyper uncertainty: economic returns; societal and regional impacts; deeper improved market engagement; improved environmental sensing and potential for dynamic capability development.

The systematic review integrates the existing fragmented research landscape regarding strategy making under hyper uncertainty, provides future research trajectories and develops a framework emerging from the review.

The framework offers port management and policymakers a tool to improve their engagement with strategy making under hyper uncertainty and associated outcomes.

The systematic review consolidates the fragmented literature and presents future research trajectories. The framework of strategy making under hyper uncertainty developed from the CIMO framework develops existing knowledge and contributes to academic theory.

The pressing issues of climate change and environmental degradation call for a reevaluation of how we approach economic activities. Both leaders and corporations are now shifting their focus, toward adopting practices and embracing the concept of circular economy (CE). Within this context, the Food and Beverage (F&B) sector, which significantly contributes to greenhouse gas (GHG) emissions, holds the potential for undergoing transformations. This study aims to explore the role that Artificial Intelligence (AI) can play in facilitating the adoption of CE principles, within the F&B sector.

This research employs the Best Worst Method, a technique in multi-criteria decision-making. It focuses on identifying and ranking the challenges in implementing AI-driven CE in the F&B sector, with expert insights enhancing the ranking’s credibility and precision.

The study reveals and prioritizes barriers to AI-supported CE in the F&B sector and offers actionable insights. It also outlines strategies to overcome these barriers, providing a targeted roadmap for businesses seeking sustainable practices.

This research is socially significant as it supports the F&B industry’s shift to sustainable practices. It identifies key barriers and solutions, contributing to global climate change mitigation and sustainable development.

The research addresses a gap in literature at the intersection of AI and CE in the F&B sector. It introduces a system to rank challenges and strategies, offering distinct insights for academia and industry stakeholders.

In this case study, we examine how a citrus peel valorising company based in the Netherlands was able to adopt a circular business model while navigating regulatory, managerial, and supply chain-related barriers.

In-depth, semi-structured interviews with key personnel in the company, notes from field observations, photographs of the production process, and documents from a legal judgement served as data for this single, qualitative case study. Data were coded inductively using the in vivo technique and were further developed into four themes and a case description.

Results from our study indicate that the regulatory and political contexts in the Netherlands were critical to the company’s success. Like in the case of most fruitful industrial symbioses, partnerships founded on mutual trust and economically appealing value propositions played a crucial role in ensuring commercial viability. Collaborating with larger corporations and maintaining transparent communication with stakeholders were also significant contributing factors. Lastly, employees’ outlook towards circularity combined with their willingness to learn new skills were important driving factors as well.

In addition to expanding the scholarship on the adoption of circular business models, this research offers novel insights to policymakers and practitioners. It provides empirical evidence regarding the importance of public awareness, adaptable legislation, and harmonised policy goals for supporting sustainable entrepreneurship in the circular economy.

This study provides empirical evidence on the impact of the Panama Canal expansion (PCE) on the economies of Latin American and Caribbean (LAC) countries, particularly in light of the emergence of larger container ships such as neo-Panamax and post-Panamax vessels.

This study uses the Bayesian structural time Series (BSTS) model to evaluate the economic effects of the PCE on 21 countries within the LAC region. It utilized the World Bank's gross domestic product (GDP) figures between 2000 and 2019 as the primary variable, alongside the human development index (HDI) (X1), container throughput (TEU) (X2) and unemployment rates (UNEMPL) (X3) covariates. This allowed a precise and robust approach to analyzing time series data while accounting for uncertainties and allowing the inclusion of various components and external factors.

The findings revealed that the PCE has a positive and statistically significant impact on most countries within the Caribbean Transshipment Triangle, ranging from 9.2% in Belize to 46% in Cuba. This suggests that the causal effect of the PCE on regional economies was not confined to any specific type of economy or geographical location within the LAC region. Where the growth rates were statistically insignificant, primarily in some Latin American countries, it coincided with countries that are primarily driven by exports and service industries, where bulk and oil tanker vessels are likely to be the main carriers for exports rather than container vessels.

The practical implications of this research are crucial for various stakeholders in the maritime industry and economic planning. The factors influencing economic growth resulting from investing in maritime activities are vital for decision-makers to create policies that lead to positive outcomes and sustainable development in regions and countries with flourishing maritime industries. The methodology and findings have significant implications for governments, managers, professionals, policy-makers and investors.

This paper aims to identify the antecedents and postcedents of customer satisfaction, including utilitarian, social and emotional factors, in a fair trade (FT) coffee consumption context.

This paper is based on a broad range of 177 consumers of FT coffee in Spain, the data analysis used structural equation modeling (SEM) with SPSS/AMOS 26.0 software.

This paper supports that both customer social value and quality affect perceived value (PV). PV in turn has effects on customer satisfaction and the latter influences loyalty. Conversely, both customer emotional value and customer expectations were not confirmed as antecedents of PV.

The consumer satisfaction analysis conducted differs substantially from those of conventionally traded coffee, as social and emotional factors were considered along with utilitarian factors.

Practitioners, retailers and relevant institutions should design strategies to manage efficiently channel efforts to improve the consumer satisfaction and its loyalty.

This paper contributes to a substantial improvement in the understanding of consumer satisfaction and its consequences, in FT coffee consumption contexts. A new integrated theoretical model on customer satisfaction has been provided, which includes social and emotional perception factors, along with cognitive perception (quality and expectations) factors.

研究旨在確認在公平貿易咖啡消費的課題上，顧客滿意的誘因及其後因，這包括實用的因素，社會的因素和情感的因素。

研究之數據廣泛來自在西班牙177名公平貿易咖啡消費者; 分析則以結構方程模型，並以SPSS Amos 26軟件來進行。

研究結果證實，顧客社會價值和質量是會影響認知價值的;認知價值繼而影響顧客滿意度，而顧客滿意度又進而影響他們的忠誠。相反的，顧客情緒價值或他們的期望、均未能證實是認知價值的先決條件。

本研究所進行的消費者滿意度分析，與其它以傳統方法銷售的咖啡之相關研究有很大的分別，這是因為本研究除了考慮實用的因素外，還納入了社會因素和情感因素。

從業人員、零售商和有關的機構應制訂適切的策略，以能有效地管理各個管道，來提升消費者的滿意度和忠誠。

本研究的貢獻在於它幫助我們在公平貿易咖啡消費的課題上，對消費者滿意及其效果有更深入的認識。研究亦提供了一個探討顧客滿意度的嶄新、綜合的理論模型，而這個理論模型，除了涵蓋知覺認知 (質量和期望) 的因素外，還納入了社會的和情感的知覺因素。
