Abstract. Internal tide energy flux is an important diagnostic for the study of energy pathways in the ocean, from large-scale input by the surface tide, to small-scale dissipation by turbulent mixing. Accurate calculation of energy flux requires repeated full-depth measurements of both potential density (ρ) and horizontal current velocity (u) over at least a tidal cycle and over several weeks to resolve the internal spring-neap cycle. Typically, these observations are made using full-depth oceanographic moorings that are vulnerable to being fished-out by commercial trawlers when deployed on continental shelves and slopes. Here we test an alternative approach to minimise these risks, with u measured by a low-frequency ADCP moored near the seabed and ρ measured by an autonomous ocean glider holding station by the ADCP. The method is used to measure the M2 internal tide radiating from the Wyville Thompson Ridge in the North Atlantic. The observed energy flux (4.2 ± 0.2 kW m−1) compares favourably with historic observations and a previous numerical model study. Error in the energy flux calculation due to imperfect co-location of the glider and ADCP is estimated by sub-sampling potential density in an idealised internal tide field along pseudorandomly distributed glider paths. The error is considered acceptable (

Abstract This article argues that the politics and governance of migrants’ rights needs to be reframed. In particular, the terms “welfare chauvinism”, and deservingness should be replaced. Using a qualitative transnational case study of policymakers in Poland and the UK, we develop an alternative approach. In fine-grained and small-scale interpretive analysis, we tease out four distinct “rationales of belonging” that mark out the terms and practices of social membership, as well as relative positions of privilege and subordination. These rationales of belonging are: temporal-territorial, ethno-cultural, labourist, and welfareist. Importantly, these rationales are knitted together by different framings of the transnational contexts, within which the politics and governance of migration and social protection are given meaning. The rationales of belonging do not exist in isolation, but, in each country, they qualify each other in ways that imply different politics and governance of migrants’ rights. Taken together, these rationales of belonging generate transnational projects of social exclusion, as well as justifications for migrant inclusion stratified by class, gender and ethnicity.

ABSTRACT The claimed detection of large amounts of substructure in lensing flux anomalies, and in Milky Way stellar stream gap statistics, has led to a step change in constraints on simple warm dark matter models. In this study, we compute predictions for the halo mass function both for these simple models and for comprehensive particle physics models of sterile neutrinos and dark acoustic oscillations. We show that the mass function fit of Lovell et al. underestimates the number of haloes less massive than the half-mode mass, $M_\mathrm {hm}$, by a factor of 2, relative to the extended Press–Schechter (EPS) method. The alternative approach of applying EPS to the Viel et al. matter power spectrum fit instead suggests good agreement at $M_\mathrm {hm}$ relative to the comprehensive model matter power spectrum results, although the number of haloes with mass $\rm{\lt} M_\mathrm {hm}$ is still suppressed due to the absence of small-scale power in the fitting function. Overall, we find that the number of dark matter haloes with masses $\rm{\lt} 10^{8}{\, \rm M_\odot }$ predicted by competitive particle physics models is underestimated by a factor of ∼2 when applying popular fitting functions, although careful studies that follow the stripping and destruction of subhaloes will be required in order to draw robust conclusions.

Many small-scale developers have shifted from a traditional, waterfall method for developing software to lighter weight, agile methods. Though the agile method is quite prevalent among small scale industries, there are several shortcomings in it. In this paper we describe the shortcomings in existing agile methodologies and the methods to overcome some impediments using Requirement Engineering. The best features of Agile and Requirement Engineering is combined and a tool is being created which acts as a repository of data.

Co-management has been promoted as an alternative approach to the governance of small-scale inland fisheries resources and has been implemented in many African countries. It has, however, not proven to be a simple solution to improve their governance; hence, most African inland fisheries are still experiencing unsustainable overexploitation of their resources. As such, there is a need for reassessing the application of governance strategies for co-management that should strive to strengthen the participation of stakeholders, primarily the local fishers, as they are fundamental in the governance of fisheries resources. Therefore, this study set out to explore the prospects of a co-management governance approach at a Lake Itezhi-Tezhi small-scale fishery in Zambia. Focus group discussions with fishers and semi-structured interviews with other stakeholders were used to collect data. This study revealed that the stakeholders perceive co-management as a feasible approach to governance of the Lake Itezhi-Tezhi fishery. However, the feasibility of the co-management arrangement would be dependent mostly on the stakeholders’ ability to address most of the ‘key conditions’ criteria highlighted in the study. This study also identified the need to establish a fisheries policy to provide guidelines for the co-management, coming with decentralisation of power and authority to the local fishers.

Purpose – The purpose of this paper is to contribute to understandings of how documents are experienced by looking to work in reception studies for methodological examples. Based on a review of research from literary studies, communication studies and museum studies, it identifies existing approaches and challenges. Specifically, it draws attention to problems cited in relation to small-scale user studies and suggests an alternative approach that focusses on how infrastructures influence experience. Design/methodology/approach – This paper presents data collected from over a year of ethnographic work at a cultural archive and exhibition space and analyses the implications of infrastructural features such as institutional organization, database structures and the organization of physical space for making available certain modes of reception. Findings – This research suggests that infrastructure provides a useful perspective on how experiences of documents are influenced by larger systems. Research limitations/implications – This research was conducted to explore the implications of an alternative research methodology. Based on the ethnographic study presented, it suggests that this approach produces results that warrant further work. However, as it is intended only to be a test case, its scope is limited, and future research following the approach discussed here should more fully engage with specific findings in relation to the experience of documents. Originality/value – This paper presents an alternative approach to studying the experience of documents that responds to limitations in previous work. The research presented suggests that infrastructures can reveal ways that the experience is shared across contexts, shifting discussions from individuals and objects to technical systems, institutions and social structures.

Impingement cooling is commonly employed in gas turbines to control the turbine tip clearance. During the design phase, computational fluid dynamics (CFD) is an effective way of evaluating such systems but for most turbine case cooling (TCC) systems resolving the small scale and large number of cooling holes is impractical at the preliminary design phase. This paper presents an alternative approach for predicting aerodynamic performance of TCC systems using a “smart” porous media (PM) to replace regions of cooling holes. Numerically CFD defined correlations have been developed, which account for geometry and local flow field, to define the PM loss coefficient. These are coded as a user-defined function allowing the loss to vary, within the calculation, as a function of the predicted flow and hence produce a spatial variation of mass flow matching that of the cooling holes. The methodology has been tested on various geometrical configurations representative of current TCC systems and compared to full cooling hole models. The method was shown to achieve good overall agreement while significantly reducing both the mesh count and the computational time to a practical level.

Chaos reigns – at least in the historiography of the Raj. It was once the consensus among historians that British imperial authority in the Indian subcontinent was secure for at least the century-and-a-half before the Second World War. Recently, however, this narrative has drawn a range of challenges. Prominently, Mark Condos and Jon Wilson have held that British imperial authority was chronically insecure. In their view, the irrational anxiety of generations of British officials produced a chaotic administration with minimal social purchase or ideological coherence. Instead of a confident state capable of acting as it chose, these historians have limned a psychologically embattled one incapable of acting except in the abstract, small scale, or short term. Their bold revision succeeds in dispelling the aura of indomitability that has often surrounded the Raj, and in directing attention to its overlooked discontents and weaknesses. Yet their characterization of the British regime as constantly and pervasively anxious is more an article of faith than a conclusion warranted by evidence. Nor do they explain how, if the regime suffered from permanent ‘chaos’ or ‘insecurity’, it managed to survive for some two hundred years. At the heart of Condos's and Wilson's approach is an effort to bypass texts that results, instead, in misreading them. It is largely by re-emphasizing rigorous textual methods, therefore, that Durba Ghosh offers a compelling alternative approach to the history of state vulnerability and disorder.

The multiple crises facing humanity at the onset of the Anthropocene are creating a moment in which agroecology acquires greater relevance as an alternative approach for meeting sustainable development goals and providing guidelines for the reconstruction of a post-COVID-19 agricultural system that is capable of minimizing future widespread disruptions of food supplies by pandemics and climate change by enhancing linkages between small-scale food production and local consumption. There are three main areas in which agroecology can be used in the development of a new post-COVID-19 agricultural system: revitalizing small farms, creating alternative animal production systems and enhancing urban agriculture. Focusing food and agricultural policies on agroecology as a main strategy for achieving autonomy and resilience can rapidly transform the ways in which we produce and consume food while addressing global challenges, including climate change, biodiversity loss, food insecurity, poverty, and deteriorating health.
