The purpose of this paper is to determine best practices of aid agencies for outsourcing logistics to commercial logistics service providers (LSPs) in disaster relief. Moreover, it evaluates the application of the Delphi method for research in humanitarian logistics.

The paper is based on a two-round Delphi study with 31 experts from aid agencies and a complementary full-day focus group with 12 experts from aid agencies and LSPs.

The study revealed 12 best practices for outsourcing logistics in disaster relief and a compilation of more than 100 activities for putting these practices into action. Experts consider a proper balance between efficiency and compliance, a detailed contract and a detailed service request most important. Additionally, the Delphi method was found to be a promising technique for research on humanitarian logistics.

By critically examining the Delphi method, this study establishes the basis for a wider application of the technique in the field of humanitarian logistics. Furthermore, it can help to prioritize future research as the ranking of practices reflects the priorities of practitioners.

The paper provides guidance to practitioners at aid agencies in charge of outsourcing logistics.

This research is one of the first in the field of humanitarian logistics to apply the Delphi method. Moreover, it addresses the lack of literature dealing with approaches for building successful cross-sectoral partnerships.

The purpose of this study is to assess the performance of fuel blends containing ethanol and gasoline in spark ignition engines. The aim is to explore alternative fuels that can enhance performance while minimizing or eliminating adverse environmental impacts, particularly in the context of limited fossil fuel availability and the need for sustainable alternatives.

The authors used the Ricardo Wave software to evaluate the performance of fuel blends with varying ethanol content (represented as E0, E10, E25, E40, E55, E70, E85 and E100) in comparison to gasoline. The assessment involved different composition percentages and was conducted at various engine speeds (1,500, 3,000, 4,500 and 6,000 rpm). This methodology aims to provide a comprehensive understanding of how different ethanol-gasoline blends perform under different conditions.

The study found that, across all fuel blends, the highest brake power (BP) and the highest brake-specific fuel consumption (BSFC) were observed at 6,000 rpm. Additionally, it was noted that the presence of ethanol in gasoline fuel blends has the potential to increase both the BP and BSFC. These findings suggest that ethanol can positively impact the performance of spark-ignition engines, highlighting its potential as an alternative fuel.

This research contributes to the ongoing efforts in the automotive industry to find sustainable alternative fuels. The use of Ricardo Wave software for performance assessment and the comprehensive exploration of various ethanol-gasoline blends at different engine speeds add to the originality of the study. The emphasis on the potential of ethanol to enhance engine performance provides valuable insights for motor vehicle manufacturers and researchers working on alternative fuel solutions.

The purpose of this paper is to evaluate some numerical integration strategies used in generalized (G)/extended finite element method (XFEM) to solve linear elastic fracture mechanics problems. A range of parameters are here analyzed, evidencing how the numerical integration error and the computational efficiency are improved when particularities from these examples are properly considered.

Numerical integration strategies were implemented in an existing computational environment that provides a finite element method and G/XFEM tools. The main parameters of the analysis are considered and the performance using such strategies is compared with standard integration results.

Known numerical integration strategies suitable for fracture mechanics analysis are studied and implemented. Results from different crack configurations are presented and discussed, highlighting the necessity of alternative integration techniques for problems with singularities and/or discontinuities.

This study presents a variety of fracture mechanics examples solved by G/XFEM in which the use of standard numerical integration with Gauss quadratures results in loss of precision. It is discussed the behaviour of subdivision of elements and mapping of integration points strategies for a range of meshes and cracks geometries, also featuring distorted elements and how they affect strain energy and stress intensity factors evaluation for both strategies.

In this paper we give a synoptic view of the growth of the text processing technology of information extraction (IE) whose function is to extract information about a pre‐specified set of entities, relations or events from natural language texts and to record this information in structured representations called templates. Here we describe the nature of the IE task, review the history of the area from its origins in AI work in the 1960s and 70s till the present, discuss the techniques being used to carry out the task, describe application areas where IE systems are or are about to be at work, and conclude with a discussion of the challenges facing the area. What emerges is a picture of an exciting new text processing technology with a host of new applications, both on its own and in conjunction with other technologies, such as information retrieval, machine translation and data mining.

Managers are constantly making decisions that affect profit. One of the decision‐making areas which is crucial to all managers concerns profit planning. Attempts to show how cost‐volume‐profit (CVP) analysis, aided by the computer spreadsheet, can be applied to the practical profit planning situation in the hospitality industry. Paradoxically, CVP analysis is one of the most widely referred to techniques in managerial accounting, but all too often it is not used to its full potential in the operating environment. Aims at encouraging greater use of the CVP approach to hospitality profit planning.

Despite the widespread study and application of public-private partnerships (PPPs) since the 1980s, the field lacks a universally accepted definition that captures the concept's complexity. This study aims to offer a definition and foster a more substantive and comprehensive discourse on PPPs to improve communication and understanding between academics and practitioners from diverse disciplines and legislative backgrounds.

Grounded in the family-resemblance concept proposed by German philosopher Ludwig Wittgenstein, this study conducts a comprehensive literature review to identify core and non-core elements frequently cited in PPP descriptions. The authors used these findings to develop the PPP sunflower model as a structured framework for defining PPPs.

The analysis elucidates six core elements consistently present in PPP descriptions: clarity of roles and responsibilities, appropriate risk allocation and sharing, injection of expertise and resources, cooperation and teamwork, a bundle of services, and long-term contracts. Coupled with identified non-core elements, these core components comprise the PPP sunflower model, a structured framework for defining PPPs that accommodates their multi-faceted nature.

The PPP sunflower model distinguishes itself as a unique contribution to the PPP literature. It offers a rigorous theoretical framework that can elucidate the complexity of PPPs for various stakeholders. The model serves as a practical tool for evaluating the authenticity and viability of PPP projects. The study's novelty lies in its adoption of the family-resemblance concept, thereby providing a comprehensive, multi-dimensional framework that enhances the understanding of PPPs across different disciplines and legislative contexts.

The purpose of this paper is to discuss the need of sustainability in its three major pillars for the future: profit, planet and people. Actions for companies and governments are listed, and a more in‐depth discussion is performed towards one of the most viable clean and renewable fuels used by society until nowadays, ethanol. The basics of this industry, the experience of Brazil in 40 years of usage of this fuel to the car fleet and recent developments are raised.

Traditional case study methodology is used to focus the analysis on the sugarcane industry in Brazil. This case study of this industry, together with previous projects done in 15 years of experience in this industry, is used to reach the objective of showing how this integrated chain works and addressing the importance of ethanol as an energy alternative for China.

China can start adopting an E10 policy (10 percent of anhydrous ethanol blended to gasoline) to contribute to reduce transport pollution in major cities. In order to have ethanol, China may invest more in the country to produce ethanol from cane and from cellulosic sources. Instead of importing oil, substitute part of its imports and consumption towards ethanol, bringing a clean fuel to the country to be blended with gasoline. China can also develop second generation ethanol to be used and generate jobs and invest in producing ethanol in some African countries and even invest in ethanol production in Brazil and import to China.

The paper is a suggestion of policies, based on the experience of Brazil. Further debate should be done to deepen the analysis of all possible points listed. It is based on a case study of one industry.

There is a preliminary suggestion of policies and strategies for the Chinese Government, together with possible partnership models and benefits to society.

China can reduce dependencies on oil and on some unstable environments; generate jobs and employment; increase relationship with Brazil and African nations, which will be future suppliers of food also to China; reduce pollution in large cities, improving the quality of the air; possibilities of international investments for Chinese people and companies, making profits outside China and repatriating this resources and contribution to mitigate climate change over the world.

The paper brings to Chinese community information about one of the most competitive bioenergy programs on the world and suggests possible ways of partnering towards sustainable development.

Does the standard of living vary from region to region in Portugal and are spatial units in Portugal converging in income? We observe spatial error dependence between municipalities and estimate spatial econometric models to test convergence. For conditional convergence we conclude that primary sector employment, activity rate, and percentage of active population with higher education are important to distinguish the “steady state” of the regional economies, reflecting the labor market at regional level.

The publication of Capital in the Twenty-First Century by Piketty (2014) propelled the debate about the prospects of the evolution of income and wealth inequalities in this century. One of the main controversies is about the effects on the income and wealth inequalities of a decrease in the growth rate g. In Piketty (2014), it is claimed that a decrease in g will cause an increase in the wealth inequality, through an increase in the difference r−g, where r is the rate of return on capital. This claim was criticized by many authors. In this chapter, the author presents a neoclassical growth model with heterogeneous agents and uses it to shed more light on this issue. The author’s model generalizes and improves previous models introduced in Piketty and Zucman (2015) and in Aoki and Nirei (2016). The author also presents a result, relating income, wealth, and wage inequalities.

On a cold Friday morning in November 2020, Aisha Mir was in utter confusion written all over her face. She had to decide on a prosperous pathway. Should it be customization or standardization of artwork? Also, whether she should continue investing in the existing in-house supply chain or outsource this to a third party. Being practicing sustainability in her personal and professional life, she had designed her art studio herself by using upcycled materials. While enjoying the pigeons and sparrows chirping and eating grains on her wide windowpane, she looked at the world map with keen interest and imagined herself flying to each country along with her gray and white pigeons. While sitting in Madina city, Saudi Arabia, she was concerned about the expired makeup collection hub being set up in Abu Dhabi, UAE. The collection and the painting processes had to be monitored; the artworks needed auditing, framing and packing before they were shipped to a customer. Centralizing would add unnecessary hassle, and outsourcing needed distribution of authority. Keeping the challenges in mind, she was struggling to find a solution for efficient community engagement.

This case has been particularly focused on undergraduate and postgraduate early-stage level students pursuing business or commerce programs, particularly those studying entrepreneurial and management courses in innovation and sustainability.
