Abstract
Purpose
The purpose of this paper is to illustrate the benefits of reintroducing traditional grazing systems practices for improving arid rangelands. Grazing is the most extensive land use in southern Tunisia, but the rangelands have suffered many decades of severe degradation due to profound socioeconomic changes and the emergence of an agro-pastoral society in place of the former pastoral one. Traditional grazing systems (gdel and herd mobility), which had historically allowed for grazing deferment and control of grazing livestock were abandoned. Yet grazing management strategies are important tools to sustain integrated livestock rangeland production systems in dry areas in the face of ongoing climate change and human pressure.
Design/methodology/approach
This study assesses the revival of traditional best practices of rangeland resting in a representative community. Total plant cover, species composition, flora richness and range production were determined in six rangeland sites subjected respectively to one, two and three years of rest; one and two years of light grazing after rest; and free grazing (control).
Findings
Results showed that dry rangelands keep their resilience to the negative effects of climate change once human pressure is controlled. A maximum of two years of rest is enough to sustainably manage the rangelands in southern Tunisia, as this protection showed considerable and positive effects on the parameters scored.
Originality/value
The revival of the traditional best practices under new arrangements adapted to current biophysical and socioeconomic conditions would be an excellent tool to mitigate the negative effects of frequent droughts and reduce the animal feed costs that poor farmers face.

Abstract
Purpose
This paper aims to examine three of the major issues relating to the welfare of seafarers, including wages, social security benefits and onboard and ashore welfare facilities and services. It is impossible to research all countries here, so this paper selects Greece – which is one of today’s primary shipping countries as for shipowning, as well as for global supply and demand for seafarers – to conduct an empirical case study.
Design/methodology/approach
Based on the existing knowledge and scholarship, and primary data collected in several phases of fieldwork, this paper intends to critically examine three major issues relating to the welfare for Greek seafarers, namely, wages, social security benefits and onboard and ashore welfare facilities and services.
Findings
This paper finds that they face poor labour conditions, which are getting worse due to the depressed world and Greek economies and intense financial pressures on shipping companies. The entry into force of the Maritime Labour Convention 2006 has a significant impact on the world maritime industry.
Research limitations/implications
This paper critically examines the three major issues relating to the welfare of Greek seafarers.
Originality/value
Such issues, which Greece is facing are also common in other countries, so the findings and suggestions revealed from this paper are of importance for the global shipping industry and other states.

Abstract
Purpose
The development of the current European economic area maritime cabotage market occurred when, at a policy level, the European Union forced the opening of its member-states cabotage markets to Community shipowners and extended this openness, in 1997, to the european free trade area countries. A two-tier cabotage market emerged, where a European economic area legislative framework co-exists with the legislative acts of each member-state. With such a unique background, this paper aims to investigate both the European economic area member-states and the rest of the world cabotage regimes and identify a list of reasons and policy measures used to implement cabotage policies.
Design/methodology/approach
By means of a desk research methodological approach, this paper analyses, from a geographical perspective, different countries’ cabotage policies and classifies them, and identifies in a systematically way a set of reasons and policy instruments that support each of chosen policies approach.
Findings
The outcome indicates that only a few countries promote free liberalised cabotage services and that most countries favour protectionist cabotage policies, whose governments can control the number of foreign vessels participating in these trades. Cabotage regimes have been categorised and the reasons behind both policies and respective policy instruments have been identified.
Originality/value
Quite often, researchers only focus on the cabotage policies of the European economic area countries, the USA, Australia, Japan and South Korea. This paper value rests on its ability to incorporate cabotage policies from other African, Asian and Latin American countries and to update existing information on the subject. Overall, this paper paves the way to broaden the cabotage knowledge.

Abstract
Purpose
This paper aims to identify ethical challenges of using artificial intelligence (AI)-based accounting systems for decision-making and discusses its findings based on Rest's four-component model of antecedents for ethical decision-making. This study derives implications for accounting and auditing scholars and practitioners.
Design/methodology/approach
This research is rooted in the hermeneutics tradition of interpretative accounting research, in which the reader and the texts engage in a form of dialogue. To substantiate this dialogue, the authors conduct a theoretically informed, narrative (semi-systematic) literature review spanning the years 2015–2020. This review's narrative is driven by the depicted contexts and the accounting/auditing practices found in selected articles are used as sample instead of the research or methods.
Findings
In the thematic coding of the selected papers the authors identify five major ethical challenges of AI-based decision-making in accounting: objectivity, privacy, transparency, accountability and trustworthiness. Using Rest's component model of antecedents for ethical decision-making as a stable framework for our structure, the authors critically discuss the challenges and their relevance for a future human–machine collaboration within varying agency between humans and AI.
Originality/value
This paper contributes to the literature on accounting as a subjectivising as well as mediating practice in a socio-material context. It does so by providing a solid base of arguments that AI alone, despite its enabling and mediating role in accounting, cannot make ethical accounting decisions because it lacks the necessary preconditions in terms of Rest's model of antecedents. What is more, as AI is bound to pre-set goals and subjected to human made conditions despite its autonomous learning and adaptive practices, it lacks true agency. As a consequence, accountability needs to be shared between humans and AI. The authors suggest that related governance as well as internal and external auditing processes need to be adapted in terms of skills and awareness to ensure an ethical AI-based decision-making.

Abstract
Purpose
Liner shipping plays a crucial role in facilitating the movement of manufactured goods around the world. While previous literature has shown that liner shipping is an important trade driver, potential differences across trade routes and world regions have not as yet been explored. This paper examines whether the impact of liner shipping on bilateral trade flows differs significantly across world regions, as well as exploring other geographical patterns.
Design/methodology/approach
Using state-of-the-art gravity modelling, this paper investigates the impact of the UNCTAD's Liner Shipping Bilateral Connectivity Index on bilateral trade in manufactured goods using a comprehensive database of disaggregated trade data for the period from 2006 to 2019.
Findings
The results show that the trade effect of liner shipping is greater in long-distance and interregional bilateral flows. For some regions, such as North America and Oceania, the effect is greater than the world average, while for others, such as Africa and South America, the effect is significantly smaller. The trade effects of liner shipping connectivity on the main east–west routes are average, but clear asymmetry emerges when analysing China's inward and outward trade flows separately.
Originality/value
The results of this paper show that the major east–west routes determine the baseline trade effects of liner shipping, demonstrate that some north–south trades such as those involving Oceania generate larger trade effects and confirm that the trade effects of liner shipping can be improved for some world regions such as South America and Africa.

Abstract
This paper aims to explore the impacts of the recent development of Korean free trade agreements (FTAs) on its seaborne trade volumes. The paper firstly estimates the changes in cargo value flows caused by Korea-EU FTA, Korea-USA FTA and Korea-ASEAN FTA using a global computable general equilibrium model named Global Trade Analysis Project (GTAP) and its most recent database - version 7 with 2004 as the base year. Then a set of systematic conversion factors transferring trade value flows to volume flows of different types of commodities is calibrated according to the United Nations COMTRADE database and is used to convert the GTAP trade value flows into volume flows. Having indentified maritime cargo flows by different commodity types, this paper attempts to draw implications for maritime logistics policy in order to facilitate the trade of Korean merchandises and to propose key competitive strategy for the maritime container transport networking and logistics service providers in the Korean logistics industry.

Abstract
Diagnosing pain in neonates is difficult but critical. Although approximately thirty manual pain instruments have been developed for neonatal pain diagnosis, most are complex, multifactorial, and geared toward research. The goals of this work are twofold: 1) to develop a new video dataset for automatic neonatal pain detection called iCOPEvid (infant Classification Of Pain Expressions videos), and 2) to present a classification system that sets a challenging comparison performance on this dataset. The iCOPEvid dataset contains 234 videos of 49 neonates experiencing a set of noxious stimuli, a period of rest, and an acute pain stimulus. From these videos 20 s segments are extracted and grouped into two classes: pain (49) and nopain (185), with the nopain video segments handpicked to produce a highly challenging dataset. An ensemble of twelve global and local descriptors with a Bag-of-Features approach is utilized to improve the performance of some new descriptors based on Gaussian of Local Descriptors (GOLD). The basic classifier used in the ensembles is the Support Vector Machine, and decisions are combined by sum rule. These results are compared with standard methods, some deep learning approaches, and 185 human assessments. Our best machine learning methods are shown to outperform the human judges.

Abstract
Purpose
This study aims to explain the facts about behavioral biases that cannot be explained by rational patterns in ship investments of small-size shipping companies.
Design/methodology/approach
A qualitative approach was adopted in this study. The systematic approach of Wolcott (1994) and the action flows proposed by Miles and Huberman (1994) were taken into consideration.
Findings
Factors affecting ship investments are classified as ship finance, market timing, ship specifications and profile and business models of ship investors. In addition, behavioral biases that stand out under each theme are explained in the light of behavioral finance literature.
Originality/value
The originality of this study rests on the lack of studies on behavioral aspects of ship investments.

Abstract
Stephen Hodgetts read the e-mail over and over again and still could hardly believe what he had read. He had just come back from his vacation, well rested and refreshed, and this e-mail had dampened his high enthusiasm. It took time to absorb such bad news and for Hodgetts to get over his incredulity.Yet in the end Hodgetts accepted the truth‐a deep, dark terrible truth that would not go away. Robert Davis, his business partner’s son, had confirmed in an e-mail his worst fears about their newest business partner, David Russ.Many thoughts were running through his mind simultaneously yet each screamed to be heard.“How could he and his partner Richard Davis have been so blind, so trusting?” “How could Russ not have heeded the advice of his business partner, Richard Davis, Russ’s former English professor?” And most important, “What was now going to happen to their new business?” Yet the one thought that continued to echo among them all was surprisingly a quote from Sir Arthur Conan Doyle’s beloved character, Sherlock Holmes: “But there are always some lunatics about. It would be a dull world without them.”

Abstract
Recent attention has been given to organizations that claim to run on faith-based principles. Activities such as at work bible study groups, charitable giving, and the individual practices of the owners are often the focus of such discussions. In such discussions little attention has been paid to those who not only hold strong religious views, but have chosen to put those views into practice‐even when it may not appear to make good business sense.
Since 1946, S. Truett Cathy, founder and chairman of Chick-fil-A Inc., has run his enterprises based on his understanding of Christian principles. Starting with his first restaurant, the “Dwarf Grill,” which he opened with his brother Ben in 1946, continuing when he opened the first “Chick-fil-A” in 1967, and even as he finished the remodeling of the companies headquarters in 1997, S. Truett says he tries “to glorify God by being a faithful steward of all that is entrusted to us and to have a positive influence on other people. . . .” In fact, this purpose is engraved in a bronze plaque that rests at the entrance to Chick-fil-A’s corporate headquarters in Atlanta, Georgia.
In practice, this purpose has lead S.Truett to never have his businesses open on Sunday, a time in the quick service industry that normally generates 20 percent of revenue. It has caused him to shut down another restaurant venture, Markos in Florida, rather than serve alcohol, which most patrons wanted. Despite his staunch adherent to principles that seem to run counter to “good business sense,” S.Truett Cathy has built a successful, privately held organization that operates in 38 states, has more than 1,300 franchisees, and generates over $2 billion a year in revenue.
In the following interview, S.Truett offers his perspective on why focusing on principles is more important than focusing on profits and what he thinks it takes to succeed in business and in life.
