Abstract
Purpose
This paper aims to examine containership routing and speed optimization for maritime liner services. It focuses on a realistic case in which the transport demand, and consequently the collected revenue from the visited ports depend on the sailing speed.
Design/methodology/approach
The authors present an integer non-linear programming model for the containership routing and fleet sizing problem, in which the sailing speed of every leg, the ports to be included in the service and their sequence are optimized based on the net line's profit. The authors present a heuristic approach that is based on speed discretization and a genetic algorithm to solve the problem for large size instances. They present an application on a line provided by COSCO in 2017 between Asia and Europe.
Findings
The numerical results show that the proposed heuristic approach provides good quality solutions after a reasonable computation time. In addition, the demand sensitivity has a great impact on the selected route and therefore the profit function. Moreover, the more the demand is sensitive to the sailing speed, the higher the sailing speed value.
Research limitations/implications
The vessel carrying capacity is not considered in an explicit way.
Originality/value
This paper focuses on an important aspect in liner shipping, i.e. demand sensitivity to sailing speed. It brings a novel approach that is important in a context in which sailing speed strategies and market volatility are to be considered together in network design. This perspective has not been addressed previously.

Abstract
This chapter discusses the growing importance of research-related information in the face of increased complexities and competitiveness within higher education environments globally. It provides some reflections on the importance of institutional research cultures to effectively address these challenges, focussing on the African context, and the role of effective research support through institutional structures such as a dedicated research office. The increasingly strategic role of research management has led to the need for a more active and visionary role in the positioning of institutions by supporting decision-making and contributing to the development and visibility of institutional research portfolios. The authors provide their insights into the scope of research-related information, the need for research offices to perform this strategic function, how these information sets can be applied in reports, evidence-based decisions, institutional showcasing, and enhanced research support. The chapter includes aspects to consider when establishing a research-related information management function within institutions.

The purpose of this paper is to evaluate the practices for valuation for compensation purposes in Kenya.
Abstract
Purpose
The purpose of this paper is to evaluate the practices for valuation for compensation purposes in Kenya.
Design/methodology/approach
A qualitative survey design was used to sample the registered valuers using questionnaire/telephone interviews, in addition to review of some policy and legal documents. Content analysis and descriptive statistics was used to analyse the data.
Findings
The study revealed that the most ignored asset losses in valuation for compensation purposes in Kenya are assets of persons without legally recognizable rights, common property resources and social capital, among others, due to the existing legal provisions. Additionally, valuers often fail to apply the appropriate valuation concepts and methods.
Research limitations/implications
The findings of the study are specific to Kenya since valuations for compensation purposes are statutory in nature and hence the applicable legal frameworks are unique to a specific country, although professionalism issues cut across.
Practical implications
The study may help professional valuers to update their knowledge and apply the right valuation concepts and methods, and also help policymakers to review their policies appropriately to match the best practices.
Social implications
The findings of the study, if implemented, are likely to enhance acceptability of compensation amounts hence improving the working relationships between the public project implementers and the project affected persons, to the benefit of the both parties.
Originality/value
The study is of value to professional valuers, policymakers and land acquiring agencies to be more vigilant and professional in the process of acquiring interests in land.

Abstract
Purpose
This paper aims to examine the compensation practices and the valuation methods valuers apply in the context of the current legal framework for expropriation to assess compensation for farms impacted by mining in Ghana.
Design/methodology/approach
Compensation reports and archival materials were examined to identify the issues related to the valuation methods, compensation practices and expropriation procedures in the mining sector. Interviews were then conducted with 35 farmers and farmers' representatives, officials of mining companies, representatives of the Land Valuation Division of the Lands Commission and valuers/researchers on the issues identified through the document analysis.
Findings
The results reveal that the lack of express standards for assessing compensation for mining-impacted crops has occasioned variations in the valuation methods and the standard crop population for compensation. The study further reveals the impacts of exchange rate distortions on crop compensation values.
Practical implications
The study empirically substantiates the arguments for a revised compensation regime in Ghana's mining sector. Valuers, mining companies and policymakers' awareness of this research will impact farm compensation valuation practices in the future.
Social implications
The adequacy of compensation for mining-impacted farmers remains a topical issue, especially in African countries. This research contributes to the literature and reveals the socio-economic impacts of the current compensation regime on the livelihoods of expropriated farmers.
Originality/value
This paper is the first to analyse the valuation methods, the compensation values and the key parameters valuers apply in assessing compensation for mining-impacted crops in Ghana.

Abstract
Purpose
This paper develops a conceptual framework that is applicable in various compensation settings vis-a-vis relevant legal frameworks, compensation processes and practices, compensation outcomes and adequacy of resultant compensation by using a common evaluative framework, to address the lack of such a conceptual framework in the compensation literature. Also, by developing a new conceptual framework, this paper provides a platform and an analytical tool for anchoring and analysing future research on compensation for expropriation of various property rights.
Design/methodology/approach
This conceptual paper is based on original thought and review of literature on compensation for expropriation.
Findings
A critical analysis of existing literature on compensation for expropriation of customary properties reveals that most studies are inadequately informed by relevant compensation theories and that each study uses its own tailor-made analytical framework. This entails that there is no general conceptual framework for anchoring new studies in compensation and aid in extrapolating their results to similar populations and contexts.
Originality/value
This paper makes novel contribution to knowledge by developing a new conceptual framework for analysing compensation for expropriation of customary property rights, which is not there currently. Essentially, by developing the new conceptual framework, this paper provides a basis for anchoring new research works in compensation and their analyses, thereby making a further contribution to knowledge.

Abstract
Purpose
The following article Chinese students' migration projects to the global south. Little work has sought to deepen the understanding of Chinese students' mobility to developing countries. This is key to determining a more complete profile of Chinese students and whether they fit into the categories of foreign students described by mainstream literature.
Design/methodology/approach
In order to understand the respective experiences and points of view of foreign students in on the process of choosing the country of study, we proceeded to identify different students of Chinese origin who have made their trip to Chile during the last decade. In addition, documents on China's international student mobility policy were reviewed, mainly focusing on documents dealing with Chinese students going abroad.
Findings
Chinese students are increasingly looking to travel to countries in the Global South as an opportunity to differentiate themselves. Chile emerges as an attractive destination as it is seen as a stable country in Latin America. It is a place where China has several strategic interests that may allow future professional development.
Originality/value
This article focuses on this aspect, mainly on how Chinese students perceive Chile as a place to pursue higher education. There is strong evidence of Chinese student flows to developed countries, but there are still insufficient studies on South-South mobility.

Abstract
Purpose
The purpose of the paper is to investigate compensation and related welfare issues in the case of the expropriation of land for urban redevelopment in China.
Design/methodology/approach
A mixed methods quantitative and qualitative approach was selected to undertake the research. This involved a wide ranging qualitative review of the academic and policy literature to explore the relevant arguments and issues, combined with a quantitative regression analysis of survey data collected from research subjects.
Findings
The research identified the complex and changeable phenomena of urban village redevelopment in China, and the variable compensation arrangements used. The research found that monthly family income before land expropriation, monthly family expense before expropriation, the location of the housing expropriation and family unit size are important determinants for the property holders chosen methods of compensation. It also found that an increase in family size leads to a decreasing probability that the expropriated farmers choose the single monetary compensation relative to the alternative option of housing compensation. The degree of satisfaction with compensation, changes in monthly family income and expense are found to be significant determinants for changes in life satisfaction.
Research limitations/implications
The research made the following four recommendations based upon the qualitative and quantitative analysis: that local governments should pay closer governance/ political attention to changes in the welfare of the farmers/ villagers whose property has been expropriated; that central and local government should aim to improve the compensation system for rural land and property expropriation, to make the compensation policy be perceived as fairer and more reasonable by citizens; that a broad National standard of compensation be used within a pragmatic locally focussed regime; that the Chinese Central, Provincial and Local governments can devise improved policy tools and make more effective policy interventions by learning from the experiences (both successes and failures) of other countries approaches to this topic. It also suggested that further research be undertaken investigating the multitude of local level policy experiments, as a way of developing better National compensation standards based upon those compensation standards that appear to be working – and have citizen support – at the local level.
Originality/value
The literature review identified recent developments in Chinese urban studies and originally synthesised both recent and longstanding work on the issue of urban villages in China. The research also suggested changes to the National and Local legal and policy framework for compensation cases in urban redevelopment expropriation scenarios.

Abstract
Purpose
This paper employs a textile reinforcement strain comparison to study the response of Textile Reinforced Mortars (TRM) strengthened reinforced concrete one-way slab members in flexure using the finite element method. Basalt TRM (BTRM) is a relatively new composite in structural strengthening applications. Experimental data on BTRMs are limited in the literature and numerical analyses can help further the understanding of this composite. With this notion, Abaqus finite element software is utilised to create a numerical method to capture the mechanical response of strengthened slab members instead of time-consuming laboratory experiments.
Design/methodology/approach
A numerical method is developed and validated using existing experimental data set on one-way slabs strengthened using Basalt TRMs from the literature. An explicit solver is utilised to analyse the finite element model created using calibrated Concrete Damage Plasticity (CDP) parameters according to the experimental requirements. The generated model is applied to extract load, deflection and rebar strains sustained by strengthened reinforced concrete slabs as observed from the experimental reference chosen. The applicability of the developed model was studied beyond parametric studies by comparing the generated finite element tensile strain by the textile fibre with available formulae.
Findings
CDP calibration done has shown its adaptability. The predicted results in the form of load versus deflection, tensile and compressive damage patterns from the numerical analysis showed good agreement with the experimental data. A parametric study on various concrete strength, textile spacing and TRM bond length obtained shows TRM’s advantages and its favourability for external strengthening applications. A set of five formulae considered to predict the experimental strain showed varied accuracy.
Originality/value
The developed numerical model considers strain sustained by the textile fibre to make results more robust and reliable. The obtained strain from the numerical study showed good agreement with the experiment results.
