Unprecedented Outbreak of Harmful Algae in Pacific Coastal Waters off Southeast Hokkaido, Japan, during Late Summer 2021 after Record-Breaking Marine Heatwaves
Authors: Kuroda Hiroshi , Azumaya Tomonori , Setou Takashi , Hasegawa Natsuki
Published: December 2021

Unprecedented large-scale harmful algae blooms (HABs) were reported in coastal waters off the south-eastern coast of Hokkaido, Japan, in mid-to-late September 2021, about a month after very intense and extensive marine heatwaves subsided. To understand the physical–biological processes associated with development of the HABs, we conducted analyses via a combination of realistic ocean circulation models, particle-tracking simulations, and satellite measurements. The satellite-derived chlorophyll concentrations (SCCs) and areal extent of the high SCCs associated with the HABs were the highest recorded since 1998. More specifically, the extent of SCCs exceeding 5 or 10 mg m−3 started to slowly increase after 20 August, when the marine heatwaves subsided, intermittently exceeded the climatological daily maximum after late August, and reached record-breaking extremes in mid-to-late September. About 70% of the SCCs that exceeded 10 mg m−3 occurred in places where water depths were <300 m, i.e., coastal shelf waters. The high SCCs were also tightly linked with low-salinity water (e.g., subarctic Oyashio and river-influenced waters). High-salinity subtropical water (e.g., Soya Warm Current water) appeared to suppress the occurrence of HABs. The expansion of the area of high SCCs seemed to be synchronized with the deepening of surface mixed layer depths in subarctic waters on the Pacific shelves. That deepening began around 10 August, when the marine heatwaves weakened abruptly. However, another mechanism was needed to explain the intensification of the SCCs in very nearshore waters off southeast Hokkaido. Particle-tracking simulations based on ocean circulation models identified three potential source areas of the HABs: the Pacific Ocean east of the Kamchatka Peninsula, the Sea of Japan, and the Sea of Okhotsk east of the Sakhalin Island. Different processes of HAB development were proposed because distance, time, and probability for transport of harmful algae from the potential source areas to the study region differed greatly between the three source areas.
Cost Effectiveness Analysis in Short Sea Shipping: Evidence from Northeast Asian Routes

Published: December 2021

Nowadays, roll-on/roll-off (Ro-Ro) is an important mode for short sea shipping (SSS) due to its advantages of fast and convenient load and unloading system. Despite the advantages, the market share of Ro-Ro is insignificant compared with lift-on/lift-off (Lo-Lo) in the Northeast Asian region that is geographically suitable for fostering SSS. Therefore, it is of utmost importance to have a better understanding of the effectiveness or Ro-Ro and Lo-Lo in the regional SSS market. For this purpose, this paper develops a model to estimate the total logistics cost of the two transportation modes. The total logistics costs of Ro-Ro and Lo-Lo are calculated on three major SSS routes between Korea and Japan. The results show that Lo-Lo outperforms Ro-Ro on most routes in terms of the cost effectiveness, and Ro-Ro is competitive only for high-priced and time-sensitive cargo. However, it is also documented that Ro-Ro transport has a significant impact on reduction in the total logistics costs when companies integrate the supply chain and improve the cooperative relationship to a high level.
Assessment of Extreme Wave Impact on Coastal Decks with Different Geometries via the Arbitrary Lagrangian-Eulerian Method
Authors: Xiang Tao , Istrati Denis
Published: December 2021

Given the documented wave-induced damage of elevated coastal decks during extreme natural hazards (e.g., hurricanes) in the last two decades, it is of utmost significance to decipher the wave-structure-interaction of complex deck geometries and quantify the associated loads. Therefore, this study focuses on the assessment of solitary wave impact on open-girder decks that allow the air to escape from the sides. To this end, an arbitrary Lagrangian-Eulerian (ALE) numerical method with a multi-phase compressible formulation is used for the development of three-dimensional hydrodynamic models, which are validated against a large-scale experimental dataset of a coastal deck. Using the validated model as a baseline, a parametric investigation of different deck geometries with a varying number of girders Ng and three different widths, was conducted. The results reveal that the Ng of a superstructure has a complex role and that for small wave heights the horizontal and uplift forces increase with the Ng, while for large waves the opposite happens. If the Ng is small the wave particles accelerate after the initial impact on the offshore girder leading to a more violent slamming on the onshore part of the deck and larger pressures and forces, however, if Ng is large then unsynchronized eddies are formed in each chamber, which dissipate energy and apply out-of-phase pressures that result in multiple but weaker impacts on the deck. The decomposition of the total loads into slamming and quasi-static components, reveals surprisingly consistent trends for all the simulated waves, which facilitates the development of predictive load equations. These new equations, which are a function of Ng and are limited by the ratio of the wavelength to the deck width, provide more accurate predictions than existing empirical methods, and are expected to be useful to both engineers and researchers working towards the development of resilient coastal infrastructure.
Improved Prediction of Sheet Cavitation Inception Using Bridged Transition Sensitive Turbulence Model and Cavitation Model
Authors: Ge Muye , Svennberg Urban , Bensow Rickard E.
Published: December 2021

Sheet cavitation inception can be influenced by laminar boundary layer flow separation under Reynolds numbers regimes with transitional flow. The lack of accurate prediction of laminar separation may lead to massive over-prediction of sheet cavitation under certain circumstances, including model scale hydrofoils and marine propellers operating at relatively low Reynolds number. For non-cavitating flows, the local correlation based transition model, γ−Reθ transition model, has been found to provide predictions of laminar separation and resulting boundary layer transition. In the present study, the predicted laminar separation using γ−Reθ transition model is bridged with a cavitation mass transfer model to improve sheet cavitation predictions on hydrofoils and model scale marine propellers. The bridged model is developed and applied to study laminar separation and sheet cavitation predictions on the NACA16012 hydrofoil under different Reynolds numbers and angles of attack. As a reference case, the open case of the PPTC VP1304 model scale marine propeller tested on an inclined shaft is studied. Lastly as an application case, the predictions of cavitation on a commercial marine propeller from Kongsberg is presented for model scale conditions. Simulations using the bridged model and the standard unbridged approach with k−ωSST turbulence model are performed using the open-source package OpenFOAM, both using the Schnerr–Sauer cavitation mass transfer model, and the respective results are compared with available experimental results. The predictions using the bridged model agree well compared to experimental measurements and show significant improvements compared to the unbridged approach.

Published: December 2021

The growing environmental awareness of society, the advancement of nature-based solutions (NbSs), and the need for reliable and cost-effective solutions create a favorable environment of opportunities for floating wetlands as alternative solutions for marine water pollution control. The aim of this work was to screen, through OpenLCA, the environmental impacts of floating wetlands for marine water pollution control at various life cycle stages of the system, and assess its economic performance and contribution to the welfare of society. The stage of raw materials production and acquisition was found to be responsible for the main environmental impacts of the floating wetlands, especially on global warming potential, whereas the main impact of the operational stage was related to the eutrophication potential due to N and P residuals in the effluent. The economic performance indicators of economic net present value (ENPV), economic rate of return (ERR), and benefits/costs ratio (B/C ratio) indicate, although marginally, that floating wetlands may constitute a viable investment with potential positive socioeconomic impacts. However, there are still several scientific challenges and technical issues to be considered for the operational application of such systems at full-scale in marine environments.

Published: December 2021

Offshore platforms have had diverse applications in the marine industry, for example, oil or gas platforms can provide facilities to store the oil and gas before transport those to refineries. Offshore wind turbines are another well-known use of the offshore platform for generating power. As platforms encounter various strong forces from water and wind currents, the materials used for these structures are mainly steel or concrete. These platforms are classified into different types, according to the depth of water and their applications. In addition, offshore platforms, as artificial reefs may be used for decades at different marine conditions. Consequently, their design and maintenance are very important, otherwise, they can cause irreparable damage to the environment. This paper presents the latest and most significant design and monitoring methods, such as the optimal probabilistic seismic demand model, multi-objective optimization, dynamic response assessment, robust fault-tolerant control, etc., under different environmental and geographical conditions. Moreover, the effective factors on the life and failure of these offshore structures are comprehensively introduced to enhance awareness of them, which can be very helpful to improve the design and construction of more reliable and durable structures.

Published: December 2021

The global greenhouse gas emitted from shipping activities is one of the factors contributing to global warming; thus, there is an urgent need to mitigate the adverse effect of climate change. One of the key strategies is to build a vibrant maritime industry with the use of innovation and digital technologies as well as intelligent systems. The digitization of the shipping industry not only provides a competitive edge to the shipping business model but also enhances ship operational and energy efficiency. This review paper focuses on the big data analytics and machine learning applied to harbour craft vessels with the aim to achieve fuel efficiency. The paper reviews the telemetry system requires for the digitalization of harbour craft vessels, its challenges in installation, the vessel monitoring and data transmission system. The commonly used methods for data cleaning are also presented. Last but not least, the paper considers two types of the machine learning systems, i.e., supervised and unsupervised machine learning systems. The multi-linear regression and hidden Markov model for supervised machine learning system and the artificial neural network, grey box model and long short-term memory model for unsupervised machine learning are discussed, and their pros and cons are presented.
Analysis of Internal Flow Characteristics of a Startup Pump Turbine at the Lowest Head under No-Load Conditions
Authors: Wang Wei , Wang Xi , Wang Zhengwei , Ni Mabing , Yang Chunan
Published: December 2021

The instability of the no-load working condition of the pump turbine directly affects the grid connection of the unit, and will cause vibration and damage to the components of the unit in severe cases. In this paper, a three-dimensional full flow numerical model including the runner gap and the pressure-balance pipe was established. The method SST k-ω model was used to predict the internal flow characteristics of the pump turbine. The pressure pulsation of the runner under different operating conditions during the no-load process was compared. Because the rotation speed, flow rate, and guide vane opening of the unit change in a small range during the no-load process, the pressure pulsation characteristics of the runner are basically the same. Therefore, a working condition was selected to analyze the transient characteristics of the flow field, and it was found that there was a high-speed ring in the vaneless zone, and a stable channel vortex was generated in the runner flow passage. Analyzing the axial water thrust of each part of the runner, it was found that the axial water thrust of the runner gap was much larger than the axial water thrust of the runner blades, and it changed with time periodically. It was affected by rotor stator interaction. The main frequency was expressed as a multiple of the number of guide vanes, that is, vanes passing frequency, 22fn. During the entire no-load process, the axial water thrust of the runner changed slowly with time and fluctuated slightly.
Disseminated Fungal Infection and Fungemia Caused by Trichosporon asahii in a Captive Plumed Basilisk (Basiliscus plumifrons)

Published: December 2021

Trichosporon spp. are heavily arthroconidiating fungi and widely distributed in nature. Due to the similar fungal morphology, confusion among Trichosporon spp., Geotrichum spp., and Nannizziopsis spp. in reptiles is apparent and cannot be overlooked. Although few reptile Trichosporon isolates have been examined using the newer speciation criteria, the information on Trichosporon asahii in reptiles is still scarce. In the present study, we report the case of disseminated fungal infection and fungemia caused by T. asahii in a captive plumed basilisk (Basiliscus plumifrons). Multiple 0.2–0.5 cm, irregularly shaped, ulcerative nodules on the left hind foot were observed. The animal died due to the non-responsiveness to treatment. A microscopic evaluation revealed the fungal infection that primarily affected the left hind foot and right lung lobe with fungal embolisms in the lung and liver. The molecular identification of the fungal species by the DNA sequences of the ITS regions and D1/D2 gene from the fungal culture and ITS regions, from formalin-fixed paraffin-embedded (FFPE) lung tissues, were completely matched to those of T. asahii. The current report describes the first confirmed case of disseminated fungal infection and fungemia caused by T. asahii in a captive plumed basilisk.
The Toxic Effects of Ppz1 Overexpression Involve Nha1-Mediated Deregulation of K+ and H+ Homeostasis
Authors: Albacar Marcel , Sacka Lenka , Calafí Carlos , Velázquez Diego , Casamayor Antonio , Ariño Joaquín , Zimmermannova Olga
Published: December 2021

The alteration of the fine-tuned balance of phospho/dephosphorylation reactions in the cell often results in functional disturbance. In the yeast Saccharomyces cerevisiae, the overexpression of Ser/Thr phosphatase Ppz1 drastically blocks cell proliferation, with a profound change in the transcriptomic and phosphoproteomic profiles. While the deleterious effect on growth likely derives from the alteration of multiple targets, the precise mechanisms are still obscure. Ppz1 is a negative effector of potassium influx. However, we show that the toxic effect of Ppz1 overexpression is unrelated to the Trk1/2 high-affinity potassium importers. Cells overexpressing Ppz1 exhibit decreased K+ content, increased cytosolic acidification, and fail to properly acidify the medium. These effects, as well as the growth defect, are counteracted by the deletion of NHA1 gene, which encodes a plasma membrane Na+, K+/H+ antiporter. The beneficial effect of a lack of Nha1 on the growth vanishes as the pH of the medium approaches neutrality, is not eliminated by the expression of two non-functional Nha1 variants (D145N or D177N), and is exacerbated by a hyperactive Nha1 version (S481A). All our results show that high levels of Ppz1 overactivate Nha1, leading to an excessive entry of H+ and efflux of K+, which is detrimental for growth.

Published: December 2021

Deoxynivalenol (DON) is one of the major mycotoxins that contaminate cereals. In this study, we determined the DON level in wheat-based products from Chinese five main production areas collected in Shanghai and calculated the daily intake of DON for inhabitants using the point evaluation and the probabilistic evaluation based on Monte Carlo simulation. The results showed the positive rates of DON in the products were higher than 80.0%, with the concentrations ranging from 41.8 to 1110 µg/kg. The estimated mean daily intakes of DON for 7- to 10-year-old children and adults groups were below 1 µg/kg bw/day, the provisional maximum tolerable daily intake (PMTDI) set by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), suggesting no health risks for the consumers. However, the 99th percentiles of dietary DON exposures for children and adults exceeded the PMTDI, indicating adverse health effects might occur if the two groups intake highly contaminated wheat-based products. The potential health risks for the two groups exposed to DON in the wheat-based products from the Middle and Lower Yangtze Valley (MLYV) were higher than those from the other areas in China.

Published: December 2021

Candida albicans (CA), a commensal and opportunistic eukaryotic organism, frequently inhabits the gastrointestinal (GI) tract and causes life-threatening infections. Antibiotic-induced gut dysbiosis is a major risk factor for increased CA colonization and dissemination from the GI tract. We identified a significant increase of taurocholic acid (TCA), a major bile acid in antibiotic-treated mice susceptible to CA infection. In vivo findings indicate that administration of TCA through drinking water is sufficient to induce colonization and dissemination of CA in wild-type and immunosuppressed mice. Treatment with TCA significantly reduced mRNA expression of immune genes ang4 and Cxcr3 in the colon. In addition, TCA significantly decreased the relative abundance of three culturable species of commensal bacteria, Turicibacter sanguinis, Lactobacillus johnsonii, and Clostridium celatum, in both cecal contents and mucosal scrapings from the colon. Taken together, our results indicate that TCA promotes fungal colonization and dissemination of CA from the GI tract by controlling the host defense system and intestinal microbiota that play a critical role in regulating CA in the intestine.

Published: December 2021

Characterising the people that work in zoos is a key element of understanding how zoos might better contribute to conservation activities. The purpose of this study was to investigate demographics, early life experiences and perceptions of zoo staff to the role of the modern zoo. This paper reports the key characteristics and qualitative themes emerging from study of international (European and Chinese) zoo professionals. Semi-structured telephone interviews were conducted with eight Chinese and eight European zoo staff about aspects of zoological animal welfare, conservation and zoological practices. These qualitative data were thematically analysed, and themes generated. This paper describes interviewee demographics and two themes relating to ‘early life influences’ and ‘the role of the modern zoo’. This analysis indicates that demographic data and early life influences of zoo professionals were broadly similar between two culturally diverse regions, but that their views on the role of the modern zoo differed, particularly in terms of their perceptions of conservation activities, with European interviewees focussing on biodiversity conservation, and Chinese interviewees focussing on animal protection.
Evidence from Studies of Patient-Reported Outcomes Supports a Policy of Using a Dialysate Sodium Concentration of 140 mEq/L for the Majority of Patients
Authors: Rayner Hugh C.
Published: December 2021

The best evidence available to guide a policy for prescribing the dialysate sodium concentration, [DNa], comes from large randomly selected observational studies, such as the Dialysis Outcomes and Practice Patterns Study (DOPPS). These show that, after adjustment for differences in demographics and comorbidity, using a [DNa] lower than 140 mEq/L is associated with patients taking longer to recover after a dialysis treatment, worse symptoms of kidney failure, a higher score for the burden of kidney disease and worse mental and physical health-related quality of life. It is also associated with greater risks of being admitted to hospital and dying. These outcomes are more important than any medically determined surrogate outcome, such as the control of blood pressure or interdialytic weight gain. The most appropriate policy for prescribing the dialysate sodium concentration is to use a [DNa] of 140 mEq/L for the majority of patients.
Resilience and Circularity: Revisiting the Role of Urban Village in Rural-Urban Migration in Beijing, China
Authors: Liu Ran , Jia Yuhang
Published: December 2021

Recent policies in China have encouraged rural-urban circular migration and an “amphibious” and flexible status of settlement, reacting against the recent risks of economic fluctuation in cities. Rural land, as a form of insurance and welfare, can handle random hazards, and the new Land Management Law guarantees that rural migrants who settle in the city can maintain their rights to farmland, homesteads, and a collective income distribution. Existing studies have pointed out that homeland tenure can reduce migrants’ urban settlement intentions (which is a self-reported subjective perception of city life). However, little is known about how the rural-urban circularity and rural tenure system (especially for those still holding hometown lands in the countryside) affect rural migrants’ temporary urban settlements (especially for those preferring to stay in informal communities in the host city). The existing studies on the urban villages in China have focused only on the side of the receiving cities, but have rarely mentioned the other side of this process, focusing on migrants’ rural land tenure issues in their hometowns. This study discusses the rationale of informality (the urban village) and attests to whether, and to what extent, rural migrants’ retention of their hometown lands can affect their tenure security choices (urban village or not) in Chinese metropolises such as Beijing. Binary logistic regression was conducted and the data analysis proved that rural migrants who kept their hometown lands, compared to their land-loss counterparts, were more likely to live in a Beijing urban village. This displays the resilience and circularity of rural-urban migration in China, wherein the rural migrant households demonstrate the “micro-family economy”, maintaining tenure security in their hometown and avoiding the dissipation of their family income in their destination. The Discussion and Conclusions sections of this paper refer to some policy implications related to maintaining the rural-urban dual system, protecting rural migrant land rights, and beefing up the “opportunity structure” (including maintaining the low-rent areas in metropolises such as Beijing) in the 14th Five Year Plan period.
Strengthening Local Governance of Secondary Forest in Peru
Authors: Sears Robin R. , Guariguata Manuel R. , Cronkleton Peter , Miranda Beas Cristina
Published: December 2021

Natural forest regrowth is critical for restoring ecosystem services in degraded landscapes and providing forest resources. Those who control tenure and access rights to these secondary forest areas determine who benefits from economically charged off-farm opportunities such as finance for forest restoration, selling carbon credits, and receiving payment for ecosystem services. We explore multiple dimensions of secondary forest governance in Peru, where the lack of official government statistics of the extent, geography, and ownership, coupled with low state capacity, prevents the development of governance structures that could stimulate their sustainable management. In this paper, we review the challenges to secondary forest governance, and the opportunities to strengthen it, focusing on beneficial outcomes for smallholder farmers. We characterize secondary forest types, extent, and persistence in Peru, followed by a presentation of the social dimensions of their governance. We identify four entry points for government to take action: national mapping of the socio-geography of second growth forest, regularize the property rights of untitled landholders, relax forest regulations, and provide incentives, not sanctions, for secondary forest management. Overall, we recommend folding secondary forest governance into a landscape approach. In Peru, strengthening local forest governance could help to drive benefits of climate change mitigation incentives directly to local forest stewards.
Which Polish Cities Sprawl the Most
Authors: Renata Różycka-Czas , Barbara Czesak , Andrzej Staszel
Published: December 2021

Spatial transformations stemming from urban sprawl are evident not only in the USA or Western Europe but also in Central and Eastern Europe, including Poland. Urban sprawl materialises mostly in land-cover and land-use change involving an increase in the proportion of urbanised areas and discontinuous urban fabric in the total area. The paper’s objective was to identify the degree of urban sprawl based on the area of discontinuous urban fabric. The spatial analysis was aimed at finding differences in land-cover ratios by individual urbanised land categories. The analysed data for 2006, 2012, and 2018 were retrieved from the Urban Atlas. The method employed was NUASI (normalised Urban Atlas sprawl indicator). A series of computations revealed that urban sprawl is found in Poland as well. Changes caused by the increase in the discontinuous urban fabric in the total urban fabric were the most pronounced from 2006 to 2012. From 2012 to 2018, the pace of the increase stabilised, but its dynamics declined. The study demonstrated a strong spatial variability of the indicator. Urban sprawl was found to be the most intense in southern and southeastern Poland.
Beliefs about Human-Nature Relationships and Implications for Investment and Stewardship Surrounding Land-Water System Conservation

Published: December 2021

When engaging stakeholders in environmental conservation, it is critical to understand not only their group-level needs, but also the individually held beliefs that contribute to each person’s decisions to endorse or reject policies. To this end, we examined the extent to which people conceptualize the interconnected relationship between humans and nature in the context of a hypothetical urban waterway, and the implications thereof for environmental investment and stewardship. We also explored how these beliefs varied based on describing the waterway as having either local or global impacts, and as originating either naturally or through artificial processes. Three hundred and seventy-nine adults from the United States read vignettes about a polluted urban waterway and thereafter reported their investment in river clean-up, their stewardship of the river, and their beliefs surrounding human-nature relationships. Results revealed a common belief pattern whereby humans were believed to impact the urban river disproportionately more than the river impacts humans, suggesting that lay adults often weigh the impacts of humans on the natural world disproportionally. Critically, this disproportionate pattern of thinking inversely predicted investment of time and money in river clean-up. Results also revealed a potential solution to this psychological bias: highlighting local benefits of the waterway decreased the asymmetry of the human-nature relationship. We discuss the psychological factors contributing to this cognitive bias, and the implications of these findings on stakeholder engagement.
Reasons for the Discontinuation of Betterment-Levy Charging in Poland (A Case Study of Gorlicki County)

Published: December 2021

Local government units carry costs related to the shaping and spatial development of communes, and are consequently interested in sharing the benefits that land property owners gain on this account. This is possible through, inter alia, the betterment levy. The aim of this study was to determine the reasons for the discontinuation of betterment levy charging in Poland, illustrated with the example of Gorlicki County. A further aim was to classify the reasons for the discontinuation of betterment levy charging in Poland, and to suggest directions for changes in the way in which this levy is charged. A questionnaire survey was conducted of the communes of Gorlicki County (Małopolskie Voivodeship), and was completed by those responsible for charging betterment levies in the communes. According to the survey results, no decision on charging of the betterment levy was issued in Gorlicki County between 2012 and 2019. The reasons for the discontinuation of charging of this levy, as indicated by the respondents, included the lack of analyses (estimation) of the increase in the property value following the execution of specific investment activities, high administrative costs related to the charging of this levy, and the stimulation of socio-economic development. However, the statistical analysis showed that the discontinuation of charging of the betterment levy in Gorlicki County had failed to contribute to socio-economic growth.

Acacia Plantation Development and the Configuration of Tree Farmers’ Agricultural Assets and Land Management—A Survey in Central Vietnam
Authors: Cochard Roland , Vu Bien Thanh , Ngo Dung Tri
Published: December 2021

Since 1990 acacia-based tree plantations have fast expanded in Vietnam, now supporting a multi-billion-dollar export-oriented wood industry which is transforming from woodchip production to value-added products. Within this dynamic context, tree farmer associations have started to produce sawlogs under FSC (Forest Stewardship Council) certification. In this paper, we retrace the development of plantation assets, investigating farmers’ current livelihoods and land management, specifically considering various aspects of sustainability. We interviewed 180 tree farmers in three districts (lowland–upland regions) of Thừa Thiên Huế Province, including sawlog producers with and without FSC and smallholder producers of woodchips. Acacia planting in ‘barren lands’ was initiated through state programs in the 1990s (low-/midlands) and 2010s (uplands). Farmers now producing FSC sawlogs were among the first to gain forestland tenure; they now own large plantations (on good terrain), are in tune with policies and maintain resources/capacities to adopt management in line with FSC standards. Yet, most farmers also retain plots for easy-to-manage and low-risk woodchip production. Soil/vegetation conservation depends on farmers’ status/capacities and environmental awareness; FSC membership added economic-political benefits. Findings are discussed within a regional historic context. Plantations contribute to economic development, but issues persist/emerged in terms of land equity and environmental governance, risks (e.g., plant pathogens), and spaces/impetus for farm-based innovation and adaptiveness.
Sediment Augmentation for River Rehabilitation and Management—A Review
Authors: Mörtl Christian , De Cesare Giovanni
Published: December 2021

Sediment management is an important part of river rehabilitation and management. Global case studies provide a growing number of examples of successful sediment augmentation measures that can counter the adverse effects of disturbed sediment regimes. The initial river state and the objectives of the reported measures can vary largely, however. In this review, a summary of selected case studies is presented, and an objective-focused classification of sediment augmentation measures is introduced. Case-specific restrictions, design approaches and assessment methods based on the literature review and our own experience from working in the field are presented. This summary aims to provide an overview on up-to-date knowledge for applied river rehabilitation and management.
Tension, Conflict, and Negotiability of Land for Infrastructure Retrofit Practices in Informal Settlements
Authors: Mesgar Mahsa , Ramirez-Lovering Diego , El-Sioufi Mohamed
Published: December 2021

Tension and conflict are endemic to any upgrading initiative (including basic infrastructure provision) requiring private land contributions, whether in the form of voluntary donations or compensated land acquisitions. In informal urban contexts, practitioners must first identify well-suited land for public infrastructure, both spatially and with careful consideration for safeguarding claimed rights and preventing conflicts. At the same time, they need to defuse existing tensions over land ownership and land use rights while negotiating for the potential use of a unit of land for infrastructure. Even in the case of employing participatory methods, land negotiations are never tension-free. Despite the extensive literature on linkages between urban poverty, inefficient land management systems, and land disputes, in both rural and urban settings, land negotiations for community-scale infrastructure retrofit projects (e.g., neighbourhood roads, water and sanitation infrastructure) are yet to be fully explored. Drawing on a case study of a live green infrastructure retrofit project in six informal settlements in Makassar, Indonesia, we establish links to exchange theory, collective action, and negotiation theory to build a reliable analytical framework for understanding and explaining the land negotiations in small-scale infrastructure retrofit practices. We aim to describe and assess the fundamental conditions for land negotiations in an informal urban context and conclude the paper by summarising several key strategies developed and used in the case study area to forge land agreements.
The Effect of Ageing, Gender and Environmental Problems in Subjective Well-Being
Authors: Ortega-Gil Manuela , Mata García Antonio , ElHichou-Ahmed Chaima
Published: December 2021

This paper studies the relationship of factors such as ageing, gender and environmental problems included in the quality of life (QoL) with the subjective well-being represented by the life satisfaction (LS) indicator of the citizens of 33 European countries. To do so, it uses the LS of a country’s citizens as the dependent variable; ageing, gender and environmental variables as independent variables; and other factors included in the QoL indicators and macroeconomic factors as control variables. Analysis uses data from the World Values Survey (WVS) and the European Values Study (EVS) for LS, from Eurostat for QoL indicators and World Bank for macroeconomic indicators. The values of LS have been treated based on the individual data from WVS and EVS in percentages according to their levels by country, and we present four robust models (two logit model and two OLS model). The results show that arrears of people aged 65 and over are a relation of positive significative in models with low levels of LS. The opposite is true for the income of people aged 65 and over. On the other hand, pollution, grime or other environmental problems and inequality show an inverse relationship with life satisfaction in models with high levels of satisfaction and a positive relationship in models with low levels of satisfaction. Nonetheless, the study has also shown contradictions in the gender gap and poverty indicators that should be studied further.

Published: December 2021

Satellite-derived lake surface water temperature (LSWT) measurements can be used for monitoring purposes. However, analyses based on the LSWT of Lake Ontario and the surrounding land surface temperature (LST) are scarce in the current literature. First, we provide an evaluation of the commonly used Moderate Resolution Imaging Spectroradiometer (MODIS)-derived LSWT/LST (MOD11A1 and MYD11A1) using in situ measurements near the area of where Lake Ontario, the St. Lawrence River and the Rideau Canal meet. The MODIS datasets agreed well with ground sites measurements from 2015–2017, with an R2 consistently over 0.90. Among the different ground measurement sites, the best results were achieved for Hill Island, with a correlation of 0.99 and centered root mean square difference (RMSD) of 0.73 K for Aqua/MYD nighttime. The validated MODIS datasets were used to analyze the temperature trend over the study area from 2001 to 2018, through a linear regression method with a Mann–Kendall test. A slight warming trend was found, with 95% confidence over the ground sites from 2003 to 2012 for the MYD11A1-Night datasets. The warming trend for the whole region, including both the lake and the land, was about 0.17 K year−1 for the MYD11A1 datasets during 2003–2012, whereas it was about 0.06 K year−1 during 2003–2018. There was also a spatial pattern of warming, but the trend for the lake region was not obviously different from that of the land region. For the monthly trends, the warming trends for September and October from 2013 to 2018 are much more apparent than those of other months.
The Acquisition of Verbal Epistemic Stance Marking during Study Abroad: The Case of je pense in L2 French
Authors: Leclercq Pascale
Published: December 2021

Epistemic stance markers, such as je pense in French, take on a variety of discursive functions, ranging from asserting an opinion, indicating the source of information, and mitigating a claim, to pragmatic functions, such as gaining time for discourse planning. Previous research suggests that the epistemic marker je pense is mostly used in French conversation to express opinions and can be used as an indicator of the development of a learner’s assertiveness and pragmatic competence during a study abroad period. Using a functional approach, this paper seeks to find out the extent to which study abroad fosters the development of assertiveness and pragmalinguistic competence among L2 learners, through an analysis of stance marking in interview data from 26 Anglophone learners of French, who spent nine months abroad in a French-speaking country, and 10 French native speakers. The results show that learners are globally less assertive in their use of je pense than native speakers, particularly prior to departure, and that they develop pragmatic uses of je pense, thereby showing a development in their interactional strategies. Finally, the high inter-variability in the way learners used je pense suggests the importance of personal style.
Function Words at the Interface: A Two-Tier Approach
Authors: Bögel Tina
Published: December 2021

The distinction between function words and content words poses a challenge to theories of the syntax–prosody interface. On the one hand, function words are “ignored” by the mapping algorithms; that is, function words are not mapped to prosodic words. On the other hand, there are numerous accounts of function words which form prosodic words and can even be analysed as heads of larger prosodic units. Furthermore, function words seem to be a driving factor for the formation of prosodic structures in that they can largely be held accountable for the non-isomorphism between syntactic and prosodic constituency. This paper discusses these challenges with a focus on a particular function word, and the first-person nominative pronoun in Swabian, a Southern German dialect. By means of two corpus studies, it is shown that the pronoun occurs in two forms, the prosodic word [i:] and the enclitic [ə]. Depending on clause position and focus structure, the forms occur in complementary distribution. Occurrences of n-insertion allow for the establishment of a recursive prosodic word structure at the level of the phonological module. The findings support a new proposal in the form of a two-tier mapping approach to the interface between syntax and prosody.
Redrawing the Map to Novel DILI Biomarkers in Circulation: Where Are We, Where Should We Go, and How Can We Get There?
Authors: Vazquez Joel H. , McGill Mitchell R.
Published: December 2021

Circulating biomarkers of drug-induced liver injury (DILI) have been a focus of research in hepatology over the last decade, and several novel DILI biomarkers that hold promise for certain applications have been identified. For example, glutamate dehydrogenase holds promise as a specific biomarker of liver injury in patients with concomitant muscle damage. It may also be a specific indicator of mitochondrial damage. In addition, microRNA-122 is sensitive for early detection of liver injury in acetaminophen overdose patients. However, recent events in the field of DILI biomarker research have provided us with an opportunity to step back, consider how biomarker discovery has been done thus far, and determine how to move forward in a way that will optimize the discovery process. This is important because major challenges remain in the DILI field and related areas that could be overcome in part by new biomarkers. In this short review, we briefly describe recent progress in DILI biomarker discovery and development, identify current needs, and suggest a general approach to move forward.

Published: December 2021

Background: Digital and smart supply chains are reforming the food chain to help eliminate waste, improve food safety, and reduce the possibility of a global food catastrophe. The globe currently faces numerous food-related issues, ranging from a lack of biodiversity to excessive waste, and from ill health caused by excessive consumption to widespread food insecurity. It is time to look back at how technology has tackled food supply-chain challenges related to quality, safety, and sustainability over the last decade. Moreover, continuous transformations of the food supply chain into a more sustainable business model with utmost resilience is the need of the hour due to COVID-19 disruptions. Method: This study aimed to systematize literature (2010–2021) in the described context and propose a future research direction, with the assistance of a systematic review and bibliometric analysis on the research agenda proposed above. Results: The findings reveal that technological Industry 4.0 (IR 4.0) tools face specific barriers due to the scope and objective of the application. Conclusion: The Internet of Things has received more attention than any other IR 4.0 tool. More integration between the specialized tools is needed to address this issue. Furthermore, the authors have proposed a food supply chain-based operational framework on technological inclusion to facilitate the roadmap for food supply chain 4.0 for more resilience and food supply chain viability.
Value Proposition Assessment of Blockchain Technology for Luxury, Food, and Healthcare Supply Chains
Authors: Berneis Moritz , Winkler Herwig
Published: December 2021

Background: In relevant research, blockchain technology (BCT) is credited with great potential for supply chain management (SCM). However, even after more than 10 years of the technology’s existence, it is barely used for any self-sustaining applications. This raises the question of why BC cannot prevail against its alternatives. With this paper we want to identify criteria by which the added value of BCT can be measured. Furthermore, we want to evaluate how well the different supply chains (SC) exploit the added values of BCT. Methods: For this, we identified real-world examples and case studies for luxury, food, and healthcare SCs. These examples are described in detail and then analyzed for their added value compared to possible alternatives. Results: The results show that in the clusters of food and healthcare SCs, no general added value of BC over current best-practice solutions could be verified. Luxury SCs manage valuable products that are typically traded in small quantities. It is within this cluster that the implementation of BC can be justified best. Conclusions: In conclusion, this study shows that the application of BCT is especially beneficial for goods with a high value and low trade volume. In addition, the interface between reality and the digital twin should be as secure as the database or BC solution itself. Furthermore, the demand for transparency and immutability of data should be more important than the need to protect sensitive data. Finally, SC participants, especially the end customer, must also be able to appreciate the advantages of BCT.

Published: December 2021

Tread wear appears as a consequence of friction, which mainly depends on surface characteristics, contact pressure, slip velocity, temperature and dissipative material properties of the tread material itself. The subsequent description introduces a wear model as a function of the frictional energy rate. A post-processing as well as an adaptive re-meshing algorithm are implemented into a finite element code in order to predict wear loss in terms of mass. The geometry of block models is generated by image processing tools using photographs of the rubber samples in the laboratory. In addition, the worn block shape after the wear test is compared to simulation results.
