The purpose of this paper is to study the uneven geographies of corruption on the African continent. Corruption is an entrenched part of African political culture. However, the degree and impacts of corruption vary widely across the continent, ranging from failed states such as Somalia to the region’s bright spot Botswana. This paper first defines corruption and discusses its causes and effects. It then delves into the specifics of African corruption, including its causes and effects such as patrimonial political cultures, clientelism and the role of natural resource exports.

The study uses data from Transparency International to assess African corruption empirically and geographically, and links its levels of severity using correlations to gross domestic product per capita, literacy, income inequality and freedom of the media.

The major findings are that while the vast majority of the continent’s one billion people live under very corrupt regimes, the impacts of corruption on economic growth are questionable. Few geographic studies of corruption exist.

The paper’s novelty stems in part from being the first to explore African corruption from a spatial perspective, illustrating its widely varying contexts and consequences.

This paper aims to investigate the wear behaviour of different materials for cylinder liners and piston rings in a linear reciprocating tribometer with special focus on the wear of the cylinder liner in the boundary lubrication regime.

Conventional nitrided steel, as well as diamond-like carbon and chromium nitride-coated piston rings, were tested against cast iron, AlSi and Fe-coated AlSi cylinder liners. The experiments were carried out with samples produced from original engine parts to have the original surface topography available. Radioactive tracer isotopes were used to measure cylinder liner wear continuously, enabling separation of running-in and steady-state wear.

A ranking of the material pairings with respect to wear behaviour of the cylinder liner was found. Post-test inspection of the cylinder samples by scanning electron microscopy (SEM) revealed differences in the wear mechanisms for the different material combinations. The results show that the running-in and steady-state wear of the liners can be reduced by choosing the appropriate material for the piston ring.

The use of original engine parts in a closely controlled tribometer environment under realistic loading conditions, in conjunction with continuous and highly sensitive wear measurement methods and a detailed SEM analysis of the wear mechanisms, forms an intermediate step between engine testing and laboratory environment testing.

This paper maps utopian theories of technological change. The focus is on debates surrounding emerging industrial technologies which contribute to making the relationship between humans and machines more symbiotic and entangled, such as robotics, automation and artificial intelligence. The aim is to provide a map to navigate complex debates on the potential for technology to be used for emancipatory purposes and to plot the grounds for tactical engagements.

The paper proposes a two-way axis to map theories into to a six-category typology. Axis one contains the parameters humanist–assemblage. Humanists draw on the idea of a human essence of creative labour-power, and treat machines as alienated and exploitative form of this essence. Assemblage theorists draw on posthumanism and poststructuralism, maintaining that humans always exist within assemblages which also contain non-human forces. Axis two contains the parameters utopian/optimist; tactical/processual; and dystopian/pessimist, depending on the construed potential for using new technologies for empowering ends.

The growing social role of robots portends unknown, and maybe radical, changes, but there is no single human perspective from which this shift is conceived. Approaches cluster in six distinct sets, each with different paradigmatic assumptions.

Mapping the categories is useful pedagogically, and makes other political interventions possible, for example interventions between groups and social movements whose practice-based ontologies differ vastly.

Bringing different approaches into contact and mapping differences in ways which make them more comparable, can help to identify the points of disagreement and the empirical or axiomatic grounds for these. It might facilitate the future identification of criteria to choose among the approaches.

This paper aims to explore how environmental employment can promote desistance among criminalised children. Research demonstrates that being immersed in and interacting with the natural environment has a positive impact upon well-being and behaviour, including reduced aggressive and violent behaviours. However, how exposure to the natural environment might promote desistance amongst children with persistent criminal involvement is unclear.

This paper examines, through semi-structured interviews and participant observations, the experiences of n = 23 criminalised children aged 16–18 employed in outdoor work at a UK social enterprise.

The findings demonstrate how working in the natural environment can provide a safe space for children, where they can build positive relationships, learn valuable skills and reconnect with the world outside of the high-pressure, conflict-driven spaces in which they typically occupy.

This research highlights the relevance of the setting in which child rehabilitation takes place and the potential role of natural environments in providing places and opportunities which support pro-social identity development and desistance for children.

The paper presents a study on whether citizens’ immigration attitudes shape their attitudes towards social welfare in three Nordic countries.

The main analysis was performed using linear regression analysis. Data were retrieved from the eighth round of the European Social Survey (2016). The data cover the Finnish, Norwegian and Swedish respondents (N = 5,021).

The analyses indicate that citizens’ immigration attitudes are associated with their social welfare attitudes. The more positive the attitudes towards immigration are, the more positive the attitudes toward social welfare will be. Further, people in the political Left have more positive attitudes towards social welfare compared to those in the political Right; but, the immigration issue is more divisive of the political Left’s opinion than that of the Right.

Public opinion research has its limitations because behind an individual’s opinion there are many hidden factors. An individual may also have different opinions depending on the dimensions of the welfare state.

If the immigration issue reduces the support for social welfare among the political Left, it may reduce the legitimacy of the Nordic social policy because the support of the political Left has traditionally been in favour of the universal principles of the welfare state.

The association of the immigration issue and social welfare attitudes has been broadly studied; but, the interaction of the immigration issue and political opinion on social welfare attitudes is less studied.

This “thought paper” is written by the special issue editors as a part of the five papers accepted and published in response to the special issue call for papers on logistics and SCM in the context of relief for refugees and internally displaced persons (IDPs) in the Journal of Humanitarian Logistics and Supply Chain Management. The purpose of this paper is to introduce the special issue on “refugee logistics” and analyse the nature and challenges of displacement from a displaced person’s perspective. The paper also argues for a more critical appreciation of the role and value that research in logistics, operations and supply chain management (LOSCM) can play in the delivery of services and care for refugees and IDPs from the perspective of preparedness and logistics planning of humanitarian organisations. The paper further outlines basic challenges to undertaking innovative, boundary pushing valuable and impactful research on “refugee logistics” given the difficult ideological, political and policy context in which “refugee logistics research” will be undertaken. The paper also advocates for more critical research in humanitarian logistics (HL), that explicitly acknowledges its ontological, epistemological and methodological limitations even when ethically sound. The paper concludes by suggesting a future research agenda for this new sub-field of humanitarian logistics research.

Conceptual paper utilising viewpoints, literature reviews as well as original ideas and thoughts of the authors.

The new field of “refugee logistics research” is important. It has been neglected in humanitarian logistics research for too long. Hence, there needs to be more research in this sub-field of humanitarian logistics.

This is a “thought paper”. It is the basic conceptual ideas of the authors. While it is not based on empirical work or data collection, it is based on a comprehensive literature research and analysis.

This paper advocates for the universal human rights of IDPs and refugees and their dignity, and how LOSCM can contribute to upholding such dignity.

It contributes indirectly to logistics policy and refugee policy as well as logistics service quality and advocacy for human rights and human dignity.

Porous implant surface is shown to facilitate bone in-growth and cell attachment, improving overall osteointegration, while providing adequate mechanical integrity. Recently, biodegradable material possessing such superior properties has been the focus with an aim of revolutionizing implant’s design, material and performance. This paper aims to present a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by mechanical alloying and spark plasma sintering (MA-SPS) technique.

This paper presents a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by MA-SPS technique. As the key alloying elements, HA powders with an appropriate proportion weight 5 and 10 are mixed with the base elemental magnesium (Mg) particles to form the composites of potentially variable porosity and mechanical property. The aim is to investigate the performance of the synthesized composites of Mg-3Si together with HA in terms of mechanical integrity hardness and Young’s moduli corrosion resistance and in-vitro bioactivity.

Mechanical and surface characterization results indicate that alloying of Si leads to the formation of fine Mg2 Si eutectic dense structure, hence increasing hardness while reducing the ductility of the composite. On the other hand, the allying of HA in Mg-3Si matrix leads to the formation of structural porosity (5-13 per cent), thus resulting in low Young’s moduli. It is hypothesized that biocompatible phases formed within the composite enhanced the corrosion performance and bio-mechanical integrity of the composite. The degradation rate of Mg-3Si composite was reduced from 2.05 mm/year to 1.19 mm/year by the alloying of HA elements. Moreover, the fabricated composites showed an excellent bioactivity and offered a channel/interface to MG-63 cells for attachment, proliferation and differentiation.

Overall, the findings suggest that the Mg-3Si-HA composite fabricated by MA and plasma sintering may be considered as a potential biodegradable material for orthopedic application.

The purpose of this paper is to demonstrate the importance of studying the quasi-legal forms of informal economic behaviour that we know as the white informal economy. The paper also sheds light on the role of the informal economy in the financial crisis that started in 2008. Finally, the aim of the paper is also to encourage empirical research about these concepts.

The paper is theoretical and based on a literature review.

The paper implies that when discussing about informal economy, different sub-categories should continue to be used in order to distinguish the various forms of informal economic practices. There is a particular need for research on practices of economic activities that are legal but not always moral, yet severely damaging. For such activities, the authors propose the term/categorisation the “white informal economy”. Additionally, the authors argue that in the causal links of events that brought about the financial crisis the role of the white informal economy was significant.

The paper wishes to encourage further research on the topic of (white) informal economy that in turn would also create the scenario for proper policy development for tackling tax avoidance, tax evasion and future financial crises.

The paper adds to scholarship that takes a critical standpoint towards the financial crisis and to scholarship on the informal economy. It presents an attempt to stimulate further discussion about the connectivity of the informal economy and the financial crisis.
