Abstract Minimum landing sizes are a fisheries management tool conventionally used to exclude juveniles from fisheries. Harvest slot limits (HSL) are an alternative fisheries management tool used to exclude both juveniles and larger individuals from a fishery through the implementation of both minimum and maximum landing sizes. However, fishery‐dependent data from HSL‐managed fisheries are only representative of a small portion of the population. These data do not meet the requirements for conventional stock assessments nor harvest control rules, so these fisheries cannot be assessed without additional and expensive fishery‐independent data. The objective of this research was to develop a novel harvest control rule able to produce catch advice for fisheries managed by HSL using fishery‐dependent data. The SlotLim method, and corresponding R package, were developed and applied to the data‐limited Scottish live ballan wrasse Labrus bergylta fishery. Within SlotLim, the advised catch is a product of the previous catch and two multipliers: the targeted biomass adjustment (TBA) and size adherence multiplier (SAM). The TBA assesses the rate of change in an abundance or biomass index, adjusted for the proportion of the population targeted by HSL. The SAM assesses fishers' compliance with HSL. The methodology follows a simple premise: the advised catch increases with increasing abundance/biomass indices and adherence to HSL. The minimum data requirements are two consecutive years of catch, length frequency and an abundance or biomass index (all from fishery‐dependent sources), species‐specific growth rate coefficients and the natural mortality rate. The SlotLim method advised catch for a reduction in catch by 17% for the Scottish ballan wrasse fishery due to an observed reduction in abundances indices and non‐adherence to maximum landing sizes. Solution. The SlotLim method allows HSL‐managed fisheries to be assessed at limited expense, contributing to the continued sustainable use of these resources. HSL may also be considered a viable strategy for other data‐limited fisheries upon the availability of this harvest control rule.

Financial violence is racial violence: geographies of housing financialization spatialize hierarchies of death-dealing racial difference. However, research concerned with housing financialization rarely addresses the inextricable relationship between racism and capitalism. Racial division and subordination have always been necessary to producing value in real estate; financialization materially reproduces racial capitalism by reconfiguring the death-dealing abstraction of racism from systems of individual bias and racialized bodies into automated systems. Rather than reducing racially subordinated communities to experiences of oppression and domination, producing life-giving geographies of housing requires bringing collective resistance for emancipatory social change into the analytic frame.

This study examines the fly ash from Soc Son municipal waste power plant (SMPP) and suggests ways to repurpose it to reduce its environmental impact. Fly ash from the Soc Son waste power plant has a gray color, spherical particles with a 5–103 μ m diameter, and a high carbon and heavy metal content. Bermorite crystals can absorb and release heavy metals, making monitoring secondary pollutants during incineration crucial. The EDX analysis of fly ash from the Soc Son waste power plant revealed that it was predominantly contaminated with metal elements, with the highest percentage of calcium. The EDX was able to detect heavy metals in incinerator fly ash. The concentration of Zn in the fly ash exceeded QCVN 07:2009/BTNMT standards, indicating the high amounts of some elements that may be hazardous to the environment and human health. Using the SEM/EDX and XRF, the fly ash from the Soc Son landfill power plant was analyzed and discovered that it exceeds permissible limits for dangerous heavy elements. The most common inorganic elements are Ca, followed by Zn, Pb, Cd, and Ag. Fly ash is classed as hazardous waste due to its high concentration of heavy metals, which results from the combustion of municipal solid waste that has not been separated. Vietnam fights municipal solid waste incinerator fly ash production. Some nations stabilize fly ash to remove harmful components and use it in buildings. Stabilized fly ash makes unfired construction bricks and cement manufacturing components and combining fly ash with inorganic trash protects the environment.

This paper uses an examination of prefigurative politics – popularly imagined as ‘being the change you wish to see’ – to reflect on geographies of the future. We argue that prefigurative politics, which has become common since the mid-1990s, typically proceeds through multiple forms of improvisation. Successful prefigurative politics is usually institutionalised within organisations and movements and reshapes practices, discourses, and structures of power. We demonstrate how a focus on prefigurative politics can inform scholarship on the ‘anticipatory politics’ associated with dominant institutions and geographies of the future more broadly by highlighting ways in which people seek to enact visions of the future and illustrating the impact of these oppositional practices of future making. We argue that prefigurative politics could be a springboard for investigating means-ends alignment as a characteristic of political action and the present as a terrain of politics.

With the continuous development of the human resource management system, the academic circle pays more and more attention to the research of employee satisfaction analysis. As one of the important factors affecting corporate performance, employee satisfaction has a significant impact on fully mobilizing employee enthusiasm. This article uses the China Family Panel Studies (CFPS) database to explore the impact of working hours characteristics and work salary characteristics on the job satisfaction of employees in stateowned enterprises and private enterprises through ordered logit regression methods. The results found that: weekly working hours and annual work income have a significant impact on these two types of employees. However, in-kind benefits and cash benefits only have a significant impact on employees of private enterprises. The one-way commute time only has a significant impact on the employees of state-owned enterprises. On this basis, this article puts forward two suggestions to improve the pertinence of welfare, strengthen the role of welfare incentives, and the government to formulate a labor standard law related to working hours, in order to improve employee job satisfaction.

<p>Streamflow is often the only variable used to evaluate hydrological models. In a previous international comparison study, eight research groups followed an identical protocol to calibrate 12 hydrological models using observed streamflow of catchments within the Meuse basin. In the current study, we quantify the differences in five states and fluxes of these 12 process-based models with similar streamflow performance, in a systematic and comprehensive way. Next, we assess model behavior plausibility by ranking the models for a set of criteria using streamflow and remote-sensing data of evaporation, snow cover, soil moisture and total storage anomalies. We found substantial dissimilarities between models for annual interception and seasonal evaporation rates, the annual number of days with water stored as snow, the mean annual maximum snow storage and the size of the root-zone storage capacity. These differences in internal process representation imply that these models cannot all simultaneously be close to reality. Modeled annual evaporation rates are consistent with Global Land Evaporation Amsterdam Model (GLEAM) estimates. However, there is a large uncertainty in modeled and remote-sensing annual interception. Substantial differences are also found between Moderate Resolution Imaging Spectroradiometer (MODIS) and modeled number of days with snow storage. Models with relatively small root-zone storage capacities and without root water uptake reduction under dry conditions tend to have an empty root-zone storage for several days each summer, while this is not suggested by remote-sensing data of evaporation, soil moisture and vegetation indices. On the other hand, models with relatively large root-zone storage capacities tend to overestimate very dry total storage anomalies of the Gravity Recovery and Climate Experiment (GRACE). None of the models is systematically consistent with the information available from all different (remote-sensing) data sources. Yet we did not reject models given the uncertainties<span id="page1070"/> in these data sources and their changing relevance for the system under investigation.</p>

Para contribuir com os debates sobre as implicações, os atores e os instrumentos geopolíticos do turismo, este artigo trata, em particular, do turismo religioso. Para tanto, baseia-se nos primeiros resultados de uma pesquisa em geografia urbana sobre o papel da indústria turístico-religiosa na formação do espaço israelense-palestino e como instrumento geopolítico do posicionamento de Israel e dos Territórios Palestinos no cenário internacional. A análise é direcionada aos lugares que contribuem para produzir este turismo e as circulações materiais e simbólicas transnacionais das quais esses lugares são objeto. São identificados três tipos de lugares - lugares de peregrinação, lugares de substituição e parques temáticos religiosos - neste campo onde a atração turística continua inabalável, apesar das ocorrências de violência. O artigo mostrará como esses lugares, que são agrupados sob o termo de “lugares de mobilidade”, se articulam e produzem o que se qualificará como “mobilidade dos lugares”.

This paper argues for expanded listening in geography. Expanded listening addresses how bodies of all kinds, human and more-than-human, respond to sound. We show how listening can contribute to research on a wide range of topics, beyond enquiry where sound itself is the primary substantive interest. This is demonstrated through close discussion of what an amplified sonic sensibility can bring to three areas of contemporary geographical interest: geographies of landscape, of affect, and of geotechnologies.
