Several economies in the Caribbean region, especially from the lower income group, are highly dependent on remittances. Between 1991 and 2006, the combined flows of total remittances reaching the Caribbean have seen almost a 17% average annual growth rate, surpassing USD 6billion in 2005 and overtaking ODA and FDI into the region. In addition, remittances represent more than 20% of the domestic gross domestic product (GDP) in some Caribbean countries and have played a significant role in lessening both balance of payment deficits and the impact of natural disasters to which the region is particularly vulnerable. Given the importance of such remittance flows, this study undertakes an analysis of the various dynamics underlying the Canada-Caribbean remittance corridor, including Caribbean migration issues, remittance market landscapes and regulatory frameworks. This study is intended to assist Canadian and Caribbean national authorities in their mandate of providing incentives for the continued growth and competitiveness of their remittance industries, while protecting remittance markets from being abused by criminals.

In Malaysia, Indonesian migrants are showing an increasingly clear preference for informal transfer mechanisms compared to their counterparts in other countries. A little less than half of all Indonesian migrants overseas—thought to be around 2 million—are working in Malaysia. An increasing number of migrants are women, and the corridor is also marked by a high number of undocumented migrants. Despite the increasing flows of migrants, only about 10 percent of the estimated flow of remittances into Indonesia from Malaysia is transferred through the formal system. The extent of the preference for the informal sector is unique in this corridor. Indonesian migrants in other countries are using the formal sector far more than the migrants in Malaysia. In addition, Indonesian women and undocumented migrants in Malaysia especially find formal sector transfers either hard to access or inappropriate for their needs. To this end, the study assists policymakers’ efforts to increase the impact of remittances on economic development and poverty reduction in Indonesia and to investigate options for attracting more migrants to use the formal financial sector. The report provides a descriptive overview of the Malaysia–Indonesia remittance corridor and suggests policy avenues for improving access to formal remittance transfer channels; increasing the transparency of the flows and the cost structure; and facilitating remittance transfers, particularly for undocumented and female migrant workers.

The UK-Nigeria remittance corridor has an equal dominance of formal and informal remittance intermediaries. Although several formal financial institutions for transferring money exist in the UK, many people choose to send money informally. More collaboration between the UK and Nigeria is necessary to develop the remittance market, to encourage the use of formal channels, and to enhance the development potential. Among its benefits, the remittance country partnership (RCP) between UK and Nigeria aims to reduce the cost of remittance transfers. The Nigerian government is engaging its diaspora to help spur economic growth. This report recommends that each government focus on improving data collection at its end of the corridor and do more research to provide its policymakers and its private sector with accurate information.

Recently, formal methods have been used in large industrial organisations (including AWS, Facebook/Meta, and Microsoft) and have proved to be an effective part of a software engineering process finding important bugs. Perhaps because of that, practitioners are interested in using them more often. Nevertheless, formal methods are far less applied than expected, particularly for safety-critical systems where they are strongly recommended and have the most significant potential. We hypothesise that formal methods still seem not applicable enough or ready for their intended use in such areas. In critical software engineering, what do we mean when we speak of a formal method? And what does it mean for such a method to be applicable both from a scientific and practical viewpoint? Based on what the literature tells about the first question, with this manifesto, we identify key challenges and lay out a set of guiding principles that, when followed by a formal method, give rise to its mature applicability in a given scope. Rather than exercising criticism of past developments, this manifesto strives to foster increased use of formal methods in any appropriate context to the maximum benefit.

ContextFormal methods (FMs) have been around for a while, still being unclear how to leverage their benefits, overcome their challenges, and set new directions for their improvement towards a more successful transfer into practice.ObjectiveWe study the use of formal methods in mission-critical software domains, examining industrial and academic views.MethodWe perform a cross-sectional on-line survey.ResultsOur results indicate an increased intent to apply FMs in industry, suggesting a positively perceived usefulness. But the results also indicate a negatively perceived ease of use. Scalability, skills, and education seem to be among the key challenges to support this intent.ConclusionsWe present the largest study of this kind so far (N = 216), and our observations provide valuable insights, highlighting directions for future theoretical and empirical research of formal methods. Our findings are strongly coherent with earlier observations by Austin and Graeme (1993).

Formal methods for industrial critical systems are essential because they provide mathematically rigorous techniques to specify, design, and verify system behavior. This reduces the risk of failures in safety- and security-critical domains such as aerospace, automotive, and healthcare. This special issue of Software Tools for Technology Transfer contains four papers presenting recent advances in tools target the use of formal methods for critical systems in industry. The papers are revised and extended versions of selected conference papers from the 29th International Conference on Formal Methods for Industrial Critical Systems (FMICS 2024).

Event-B is a formal method for system-level modelling and analysis. Key features of Event-B are the use of set theory as a modelling notation, the use of refinement to represent systems at different abstraction levels and the use of mathematical proof to verify consistency between refinement levels. In this article we present the Rodin modelling tool that seamlessly integrates modelling and proving. We outline how the Event-B language was designed to facilitate proof and how the tool has been designed to support changes to models while minimising the impact of changes on existing proofs. We outline the important features of the prover architecture and explain how well-definedness is treated. The tool is extensible and configurable so that it can be adapted more easily to different application domains and development methods.

A prerequisite for the durability of authoritarian regimes as well as their effective governance is the regime’s ability to gather reliable information about the actions of lower-tier officials. Allowing public participation in the form of online complaints is one approach authoritarian regimes have taken to improve monitoring of lower-tier officials. In this paper, we gain rare access to internal communications between a monitoring agency and upper-level officials in China. We show that citizen grievances posted publicly online that contain complaints of corruption are systematically concealed from upper-level authorities when they implicate lower-tier officials or associates connected to lower-tier officials through patronage ties. Information manipulation occurs primarily through omission of wrongdoing rather than censorship or falsification, suggesting that even in the digital age, in a highly determined and capable regime where reports of corruption are actively and publicly voiced, monitoring the behavior of regime agents remains a challenge.

Rapid urbanisation in China has led to a substantial decrease in agricultural land. To address this unsustainable form of urban development, the Chinese government has implemented the ‘Linkage’ Policy (Zengjian Guagou), which requires any increase in new urban land by local governments to be compensated for with an equivalent amount of new arable land. This paper examines the institutional changes and the implications for China’s land production and development arising from this mechanism of transferring land development rights from the rural to the urban sectors. Using Chengdu as a case study, our research concludes that this institutional mechanism has conferred commodified and tradeable development rights on rural land, leading to the emergence and direct involvement of new players in village land consolidation, resettlement of affected villagers and, indirectly, in the supply of new urban land. Process efficiency has been improved with the local governments, developers and village collectives capitalising on their niches in village improvement projects. The conventional state-led model of land production is enriched with bottom-up market initiatives, and villagers have more choices to realise their land property rights under the dual land market. Land use efficiency has been enhanced by the reallocation of construction land potential. However, infringements of villagers’ interests and negative impacts on balanced regional development under this policy were also found. 中国城市化的快速发展导致了农业用地的大幅减少。为了应对这种不可持续的城市发展形式，中国政府实施了“增减挂钩”政策，它要求地方政府在增加新城市土地的同时用同等数量的新耕地进行补偿。本文考察了这种土地发展权从农村向城市转移的机制，以及该制度变迁对中国土地生产和开发所产生的影响。以成都为例，我们的研究得出以下结论：这种制度设计赋予了农村土地商品化的、可交易的发展权，致使新的参与者出现并直接参与乡村土地整理、受影响村民的重新安置，并使他们间接参与到新的城市土地供应中。地方政府、开发商和村集体利用其各自在村庄发展项目中的优势提高了过程效率。传统的国家主导型土地生产模式因融合了自下而上的市场主动性而更为丰富，村民在二元土地市场下拥有了更多的选择以实现其土地产权。通过重新分配建设用地潜力，土地利用效率也得以提高。然而，在这一政策下，也出现了侵犯村民利益的现象和对区域均衡发展所产生的负面影响。
