The economic displacement of thousands of fishers in the Pantanal, Brazil: A telling story of small‐scale fisheries marginalization worldwide.

AbstractA new policy in the Pantanal wetland, Brazil, aims to economically displace thousands of artisanal fishers from one‐third of the region. The legislation disregards several FAO Voluntary Guidelines for Securing Sustainability in Small‐Scale Fisheries' guiding principles (SSF guidelines). Considering that 2024 marks the 10th anniversary of these guidelines, this policy represents a significant setback for fish and fisheries worldwide. In this paper, we show that the legislation is part of long‐term agenda against small‐scale fishers in the Pantanal, aiming to use narratives around overfishing to justify physical and economic displacements—albeit no empirical evidence showing impact on fish stocks. We also show that, as in many other small‐scale fisheries worldwide, overfishing narratives are, in fact, used to open space for industrial activities and large infrastructure projects. The Pantanal is a telling story of that, since the new legislation will likely open space for the construction of over 50 small hydroelectric dams in the Pantanal and surrounding area. We argue that, first, it is urgent to abolish the new legislation and promote a pro‐fishers agenda in the Pantanal to protect the region. However, since this is not unique for the region, it is critical to implement international programmes that celebrate and support local fisheries worlwide and avoid physical and economic displacements. Stands out turning SSF guidelines into international agreements, implementing citizens science programmes and expanding the fisher's tenure rights through innovative mechanizes of ownership. By better protecting local small‐scale fishers in the Pantanal and worldwide we are more likely to guarantee a sustainable future for ecosystems and its peoples.

Exploring Reinforced Class Separability and Discriminative Representations for SAR Target Open Set Recognition

Current synthetic aperture radar (SAR) automatic target recognition (ATR) algorithms primarily operate under the closed-set assumption, implying that all target classes have been previously learned during the training phase. However, in open scenarios, they may encounter target classes absent from the training set, thereby necessitating an open set recognition (OSR) challenge for SAR-ATR. The crux of OSR lies in establishing distinct decision boundaries between known and unknown classes to mitigate confusion among different classes. To address this issue, we introduce a novel framework termed reinforced class separability for SAR target open set recognition (RCS-OSR), which focuses on optimizing prototype distribution and enhancing the discriminability of features. First, to capture discriminative features, a cross-modal causal features enhancement module (CMCFE) is proposed to strengthen the expression of causal regions. Subsequently, regularized intra-class compactness loss (RIC-Loss) and intra-class relationship aware consistency loss (IRC-Loss) are devised to optimize the embedding space. In conjunction with joint supervised training using cross-entropy loss, RCS-OSR can effectively reduce empirical classification risk and open space risk simultaneously. Moreover, a class-aware OSR classifier with adaptive thresholding is designed to leverage the differences between different classes. Consequently, our method can construct distinct decision boundaries between known and unknown classes to simultaneously classify known classes and identify unknown classes in open scenarios. Extensive experiments conducted on the MSTAR dataset demonstrate the effectiveness and superiority of our method in various OSR tasks.

Small Open Space

People can participate in the public realm by using public open spaces. In contrast to the setting of home or job, it is a place where people can physically join the larger community. The absence of neighbour interactions and the isolation of people as a result of a lack of well-maintained public open spaces have been characteristics of a new emerging town. Many public open places around the world have been underappreciated and severely neglected. A well-planned public open space would entice residents to leave their homes and participate in a variety of activities. When it comes to use and occupancy, this can raise the quality of the area. By evaluating the architectural and urban elements of the public open spaces, this research intends to discover and analyse dysfunctional public open spaces and weak linkages in those areas, and come up with solutions to improve these spaces and stimulate public life.

Kajian Tentang Ruang Terbuka Hijau di Kecamatan Tenggarong Kabupaten Kutai Kartanegara

This study discusses the green open space needed by every urban area in Tenggarong District. For this reason, this action aims to find out the condition of the area and the community's response to the existence of green open spaces in Tenggarong District. This research used a descriptive qualitative method. All the data used in the research came from observation, interviews and documentation which were then supported by other relevant data. The results show that green open space is a very vital need and must exist in urban areas with conditions that are progressing in development at any time. The condition is still below the minimum standard required for green open space, which is only 18.17%. For other results, it was stated that 46.7% agreed with green open spaces, 33.3% agreed, 20% disagreed. For this reason, green open space facilities and infrastructure must be considered by the government for the convenience of the community.

Analysis of Public Satisfaction Levels in Gelora Bung Karno (GBK) City Forest Based on Socio-Cultural Functions

The Jakarta City Government, along with the central government, has implemented various measures to address the issue of air pollution that has become a serious problem for the city. One of the efforts undertaken is to increase the provision of urban green spaces and restore the function of the GBK City Forest as a public green open space (GOS). However, there has been no research showing the public's perspective and satisfaction with the utilization of the GBK City Forest. This study aims to determine the level of public satisfaction with the GBK City Forest based on social-cultural functions. The assessment indicators used to measure public satisfaction in this study are based on the theory of cultural ecosystem services developed by Shijie Gai et al. The data used in this study were obtained using mixed methods data collection techniques through questionnaires (quantitative) as well as in-depth interviews and literature studies (qualitative). Based on the results of the study, it can be concluded that the majority of the public is highly satisfied with the utilization of the social-cultural functions of the GBK City Forest. However, some people still complain about the lack of supporting facilities for recreational activities and the disturbances from external parties that make them feel uncomfortable when engaging in activities at the GBK City Forest. Therefore, it is important for the government and the GBK City Forest management to consider public feedback and improve the quality and safety of the existing facilities.

Assessment of low impact development (LID) strategies under different land uses in an urban sub-catchment in the Philippines

Lack of studies in developing countries with tropical climate such as the Philippines limit local LID adoption. This study compared the performance of different LID scenarios across different urban land use types at the sub-catchment level using peak flow, runoff volume and flood reductions as performance criteria. Results showed that the most effective strategies for each land use are: 1) combined green roof and bioretention for low-density residential (reduction up to 10% peak flow, 11% runoff volume and 33% flood volume); 2) green roof for high-density residential (8% peak flow, 6% runoff volume and 18% flood volume); 3) combined rain barrel, bioretention and permeable pavement for industrial (23% peak flow, 41% runoff volume and 56% flood volume), and 4) combined vegetative swale and detention pond for urban open spaces (81% peak flow, 8% runoff volume and 84% flood volume). While effective for most low intensity storms, the observed sharp decrease in LID performance with increased rainfall intensity poses a major challenge, especially in the context of the Philippines frequented by high intensity storms. This study also examined how differences in land use characteristics influence LID performance, unlike most studies that focused on LID type comparisons. It showed that low urban density setting positively affected peak flow and flood reduction performance of rain barrels and green roofs, while good drainage infrastructure quality positively affected peak flow and flood reduction performance of rain barrels and bioretention. Decision-makers may use these findings to conduct rapid assessments on LID selection and siting, provided similarities between land use characteristics described in this study and those at their localities are justified. This can lead to increased LID adoption towards building water resilient, and sustainable cities.

Formation of directed wide-aperture flows of runaway electrons in air-filled magnetized diodes.

This paper presents the results of research, development, and testing of magnetically insulated air diodes with replaceable graphite and stainless-steel tubular and coaxial cathodes of various configurations capable of generating directed bunches of runaway electrons. At the anode, the bunches have cross sections shaped as circles or rings with an outer diameter of 1-2cm. The durations of the bunches, which carry currents of a few to tens of amperes, range from tens of picoseconds to 100ps, and their charges range from tenths of a nanocoulomb to a few nanocoulombs. The kinetic energy of the bunch electrons at the peak of the current pulse is typically of the order of 150keV. The bunch parameters are set (and varied) by varying the amplitude and duration of the subnanosecond high-voltage pulse driving the diode; they depend on the cathode material and on the strength and profile of the applied external magnetic field. The bunches, retaining their cross-sectional structure, are brought out from the diode, along the field lines, through a thin foil or mesh anode into the open space with a quasi-uniform magnetic field between two Helmholtz coils. In this space, the samples to be irradiated with electrons, similarly to objects exposed to radiation in various experiments and technological applications, can be placed.

Thermal comfort in open spaces in the arid climate of Kuwait: a study of construction training institute students

This article assesses the students’ sensation of thermal comfort in the open areas of the construction training institute in Kuwait, a hyper arid desert. This is carried out using field measurements from the site, and then handing out in-depth questionnaires to 100 students. The questionnaire provides great insight into the students’ perception of thermal comfort, as well as the constituents that impact it. Moreover, the students’ recommendations to improve thermal comfort in open spaces sheds light on the various methods that should be further researched and quantified. These solutions include adding substantial vegetation and trees for shading and redesigning the inadequate existing shading devices on campus. Overall, the findings indicate that the air temperature and humidity are well below the comfort level. These field measurements are sufficiently validated with the questionnaire results that indicate a substantially negative experience. While outdoor thermal comfort is heavily under researched in Kuwait, there are endless opportunitiesfor improvement and development. Consequently, this paper acts as a catalyst for future endeavors, quantitative analysis, and raised awareness

43 Involvement in active transport is related to organizational factors and physical environment infrastructure

Abstract Purpose Active transport (AT) is considered the most sustainable and accessible mode for travel purposes. AT (walking and cycling) contributes to health-enhancing physical activity as it is a convenient and accessible way to increase physical activity levels. Convenient infrastructure promotion and support are important factors in shift from motor transport towards active travel. The purpose of this study was to determine how organizational factors and neighbourhood physical environment differ between using and not using AT among the Lithuanian young adult population. Methods This cross-sectional study included 250 Lithuanian young adults aged 18-39 years, with a mean age of 20.38 years. Of these, 80% were women. AT was measured using the Stages of Change Model-based Questionnaire. Infrastructure was measured by ALPHA Questionnaire–REVISED (Spittals et al., 2010). Organization-related items were developed by study researchers. Results Young Lithuanian people preferred cars and/or public transport (62.4%) instead of active transportation (AT) (27.6%) when choosing mobility. The results support a strong link between AT and organizational aspects. AT is more often chosen by people who belong to an organization where environmentally friendly behaviour is encouraged (waste sorting, using AT (p = 0.018); conditions are created to safely store a bicycle or scooter (p = 0.024); that talks about sustainable development, environmentally friendly behaviour, sustainability, etc. (p = 0.034). Quality of the neighbourhood physical environment, such as maintained bicycle paths (p = 0.011), maintained sidewalks (p = 0.049), maintained parks, and other open spaces (p = 0.050) significantly associated with the choice of AT. However, the choice of active transport was not significantly related to the infrastructure of pedestrian zones or paths, infrastructure of special lanes, routes for bicycles, or separation of bicycle paths from car traffic. Conclusions Young people’s involvement in AT is influenced by the attitude of the organization in which they work or study towards environmentally friendly behaviour, AT, and sustainable development. The quality of the neighbourhood physical environment also determines the involvement of young people in AT.

Optimizing column location in flat slab system using Particle Swarm Optimization vs Genetic Algorithms

Abstract One of the key architectural advantages of a concrete flat slab system is its flexibility in design. The absence of beams and columns allows for larger, open spaces with minimal obstructions, giving architects the freedom to create unique and innovative layouts. However, the location of the middle columns (one of the main factors affecting the construction cost) is commonly aligned based on experience which may entail an uneconomic design alternative. This paper aims to propose different machine learning optimization algorithms, namely, particle swarm optimization (PSO) and genetic algorithms (GA) to optimize the location of columns within a flat slab plan considering different serviceability requirements. Both optimization systems showed good performance for allocating the concrete columns, However, the GA algorithm showed better results in terms of maximum deflection with less computational effort.

Stand-off concealed firearm detection using motion tracking and convolutional neural networks

<p>The standoff detection of concealed firearms is crutial in managing public security in public spaces. Currently employed standoff concealed weapon detection techniques employ electromagnetic wave imaging which has been found to be extremely slow and may require expensive hardware and may not be applicable in public open spaces. Inorder to maintain safety in open spaces, artificial intelligence enabled video surveillance systems have been widely adopted. This poses an opportunity to explore video surveillance cameras as concealed weapon detectors. A review of existing video surveillance based automated weapon detection approaches discovered that the focus was on the detection of unconcealed firearms leaving a gap in the detection of concealed firearms. This study addresses the aforementioned gap by providing a standoff concealed firearm detection approach on video based on skeletal-based human motion tracking and convolutional neural networks. The motion of armed and unarmed persons was tracked using a depth camera and further classified using convolutional neural networks model. The developed model reported 100% accuracy, precision and recall scores. These results outperformed results obtained from traditional machine learning models therefore highlighting the superior capability of the proposed approach for concealed firearm detection on video to complement the efforts of human video surveillance operators.</p>

Crowdsourced data as a strategic approach to include the human dimension in outdoor environmental quality assessments

Outdoor environments extend living spaces as venues for various activities. Comfortable open public spaces can positively impact citizens' health and well-being, thereby improving the livability and resilience of cities. Considering the visitors' perception of these environments in comfort studies is crucial for ensuring their well-being and promoting the use of these spaces. However, traditional survey methods may be time- and resource-consuming to gather significant sample sizes, usually focusing on selected homogeneous samples. Crowdsourced data, then, has emerged as an alternative for assessing human perception, as it eases the collection of subjective feedback and potentially amplifies impact and inclusivity. This study presents a strategic approach for analyzing publicly available and willingly reported crowdsourced data from a digital mapping platform in outdoor comfort evaluations, aiming to verify whether these data are informative regarding environmental quality perception and to identify the environmental factors that people are most sensitive to. Urban parks located in New York City served as a case study. A multi-source, interdisciplinary information framework combined crowdsourced reviews with environmental data used to determine prevailing thermal conditions. Overall perception of parks was well-rated, revealing that their attractions and activities are probably the most appealing characteristics for park attendance. Regarding environmental perception, acoustic and thermal factors are clearly the most influential. Acoustics were well-rated, while the main aspect regarding the thermal domain is the recognition of shading as a mitigator for hot conditions. Environmental data provided complementary insights, particularly concerning the range of thermal sensations experienced in urban parks. The findings confirm that willingly reported crowdsourced data can provide valuable insights into urban crowd environmental perception, presenting a potentially suitable and effective method to include the human perspective in environmental quality assessments, as well as to evaluate and predict environmental-related risks.

Public space and everyday heritage: An inquiry into children's and adults' perception

This paper examines how the spatial environment and the activities within these spaces contribute to their social value in turn informing the concept of everyday heritage within urban public spaces. We develop a novel methodological framework that combines visual representation and narrative analysis to provide insights into how the physical, emotional and perceptual dimensions of a public open space translate into associative social values. By including both adults and children in our study, we capture a comprehensive range of perceptions, highlighting the diverse ways in which different user groups give meaning to everyday heritage. Children and their guardians showed agreement on natural elements and personal representations, but differed on the garden's spatial layout and activities. While they shared values like childhood memories and family time, children prioritized play, forming new friendships, and connecting with nature, whereas parents emphasized children's happiness and personal space. Notably, both groups indicate that childhood – both lived and remembered – is that which gives this public urban space its everyday heritage status. The findings advocate for an expanded understanding of urban public spaces, recognizing the significance of everyday heritage in shaping collective cultural identity.

Foucault and Wittgenstein: Practical Critique and Democratic Politics

This paper aims to explore a set of convergence points between Foucault’s and Wittgenstein’s perspectives on philosophy and language, integrating them into a mutually complementary approach that I term ‘practical critique.’ The concept of ‘practical critique’ is founded on three pillars: the understanding of philosophy and language as critical practices, the public nature of language, and confessional subjectivity. I examine these three areas of convergence across three subsequent sections. In the concluding section, I discuss how this perspective can be fertile for understanding democratic politics today. I argue that all three pillars predominantly support democratic politics over any other political form. To explain that, I engage with the debate on the language of democratic theory and the potential expansion of the understanding of the public sphere. The notion of the public that emerges from this perspective offers an alternative or supplementation to the classical Habermasian view of the public sphere and democratic theory. It is envisioned as an open space of discursive multiplicity and diversity, where practices of exclusion or oppression can be made visible, challenged, and resisted.

Early Pliocene Spalacinae from the locality of Afşar, western Turkey

Spalacinae are an unusual component of the fossil record around the world with a limited geographical distribution. The revisited section of Afşar includes one of the richest collections of Spalacinae in Turkey. From Afşar 1, near the base of the section we recovered Pliospalax cf. macoveii while in Afşar 2, at the top of the section we distinguish the species P. tourkobouniensis. The current research includes the first record of the last-mentioned species outside of Europe. Both spalacines indicate a dry and open space environment and, in accordance with the Arvicolinae, suggest that Afşar 1 can be attributed to MN 15 while Afşar 2 is correlated to MN 16.

Mapping and Assessing Effective Participatory Planning Processes for Urban Green Spaces in Aotearoa New Zealand’s Diverse Communities

The multicultural landscape of Aotearoa New Zealand presents a rich tapestry of diversity and community needs, underscoring an imperative for inclusive participatory planning processes. This paper presents findings from an investigation of the challenges and opportunities inherent in community engagement initiatives, particularly within the context of New Zealand’s major ethnic groups, including New Zealand European, Māori, Chinese, and Pasifika. Drawing from the importance of community participation in reshaping public open spaces, this research addressed the gap in understanding which participatory planning processes are most effective across diverse cultural groups. To investigate the effectiveness of various approaches to community engagement, this research involved focus groups from the Wellington suburbs of Newtown and Porirua, utilising both on-site and online meetings. The findings identify the most effective participation processes for planning public open spaces in relation to each ethnicity. Correlations between participant preferences and their unique cultural backgrounds were assessed. In addition, the least effective participation methods along with several relatively effective participation methods are discussed. By highlighting engagement methods that can foster inclusivity, equity, and a sense of community, this research advances a collective goal of building a more cohesive and effective society for all its inhabitants.

Экспериментальные исследования горения смесей водорода, кислорода и азота в частично ограниченном пространстве

Experimental studies of the peculiarities of combustion of hydrogen, oxygen, and nitrogen mixtures in a partially confined space when changing the space limitation within the wide range from 12 to 81 % of the total space, e.g., premises, industrial sites, or stands where hydrogen and oxygen spills or their discharge in a gaseous state are potential, have been carried out. The experiments have been conducted on a stand with hydrogen and oxygen mixtures containing nitrogen 2Н2 + О2 + 2N2 and hydrogen and oxygen mixtures 2Н2 + О2. According to the results of the studies, partial limitation of the space does not significantly affect the combustion rate of such mixtures. At the same time, during combustion in a partially confined space, the pressure in the compression wave increases compared to the pressure in a free space. Increasing the space limitation during ignition caused pressure rise in the mixture compression waves. During the tests with 2Н2 + О2 + 2N2 with one wall of the stand space limitation, at the ignition of the mixture, pressure sensors placed opposite the wall registered, on average, a 50 % higher pressure compared with the sensors facing the open space. These sensors showed the same pressure values as for the mixture combustion in a free space. The increase of the installation space limitation with three walls during ignition led to further pressure rise in a partially confined space. The same effect has been registered for 2Н2 + О2 mixtures. During the experiments, the limitation of the installation’s free space with only one wall caused the double rise of blast wave compression pressure compared with experiments without a wall. The results of studies confirm that with the increase of the stand space limitation, the mixture ignition pressure increases, which is conditioned by the interaction of falling and reflected waves.

Spatiotemporal landscape pattern changes and their effects on land surface temperature in greenbelt with semi-arid climate: A case study of the Erbil City, Iraq

Urban expansion of cities has caused changes in land use and land cover (LULC) in addition to transformations in the spatial characteristics of landscape structure. These alterations have generated heat islands and rise of land surface temperature (LST), which consequently have caused a variety of environmental issues and threated the sustainable development of urban areas. Greenbelts are employed as an urban planning containment policy to regulate urban expansion, safeguard natural open spaces, and serve adaptation and mitigation functions. And they are regarded as a powerful measure for enhancing urban environmental sustainability. Despite the fact that, the relation between landscape structure change and variation of LST has been examined thoroughly in many studies, but there is a limitation concerning this relation in semi-arid climate and in greenbelts as well, with the lacking of comprehensive research combing both aspects. Accordingly, this study investigated the spatiotemporal changes of landscape pattern of LULC and their relationship with variation of LST within an inner greenbelt in the semi-arid Erbil City of northern Iraq. The study utilized remote sensing data to retrieve LST, classified LULC, and calculated landscape metrics for analyzing spatial changes during the study period. The results indicated that both composition and configuration of LULC had an impact on the variation of LST in the study area. The Pearson’s correlation showed the significant effect of Vegetation 1 type (VH), cultivated land (CU), and bare soil (BS) on LST, as increase of LST was related to the decrease of VH and the increases of CU and BS, while, neither Vegetation 2 type (VL) nor built-up (BU) had any effects. Additionally, the spatial distribution of LULC also exhibited significant effects on LST, as LST was strongly correlated with landscape indices for VH, CU, and BS. However, for BU, only aggregation index metric affected LST, while none of VL metrics had a relation. The study provides insights for landscape planners and policymakers to not only develop more green spaces in greenbelt but also optimize the spatial landscape patterns to reduce the influence of LST on the urban environment, and further promote sustainable development and enhance well-being in the cities with semi-arid climate.
