Published: January 2023

In this study, chromate adsorption onto red peanut skin (RPS) was investigated in a fixed-bed column; FTIR, PZC, SEM, DLS, and BET were used to evaluate its adsorption properties. The experiments were conducted to determine the effect of physical parameters, including the inlet initial Cr(VI) concentration (100–500 mg L−1), bed height (10–20 cm), and feed flow rate (13.59–23.45 mL min−1). They were carried out to predict breakthrough curves. The adsorption capacity coefficients were determined using the most widely used Bohart–Adams model. It was tested to fit experimental data, for a better understand the dynamic behavior, and for further optimize column performance. It was found that the Cr(VI) uptake decreases when increasing the flow rate and that high chromate concentration and bed height consequently increase the column’s life span. A high column adsorption capacity can be achieved with a higher Cr(VI) concentration due to the higher driving force. The results indicated that the Bohart–Adams model provides a good description (R2 > 0.98) of the experimental data of the Cr(VI)’s removal from the aqueous solution on the RPS suggesting that the surface diffusion is the rate-limiting step in the continues adsorption process.. Breakthrough adsorption capacity is crucial for comparing RPS with other similar materials. Indeed, possible mechanisms have been suggested for illustrating adsorption onto RPS. The obtained results showed significant potential of 26.23 mg g−1 of RPS on Cr(VI) elimination at a natural pH of 5.35. Furthermore, this global investigation allowed for the design of a promising low-cost material for the future scale-up of cleaning wastewater polluted by metal and determine the properly conditions for operating column adsorption. This material provides an economical, efficient means of eliminating pollutants, thus meeting the main aims of the UN Sustainable Development Goals (UN SDGs).

Published: January 2023

In order to reduce the impact of the leg joint motors and body electric devices of a falling robot, active flexible control based on force and velocity is proposed. A velocity planning buffer method based on a virtual model is proposed. We established a mechanical model of leg and ground contact. Then, we controlled the knee joint angular velocity change after the robot contacted the ground to reduce the collision impact force and to protect the robot’s joint motors and body’s internal parts. First, the relationship between contact force and velocity was analyzed through the contact mechanical model between leg and ground, and the target was determined. Then, by planning the velocity of the robot’s thigh and hip joint, the velocity mutation during contact was reduced so that the impact on the robot was reduced. This method can avoid complex accurate physics model building and complex torque signal interference filtering processing, the control process is simple and its effectiveness is verified by ADAMS simulation and experimental verification. The velocity planning buffer strategy was tested in experimental studies which showed that the contact force of the buffer strategy was 0.671 times that of no buffer. Additionally, the contact impact acceleration of velocity planning was 1.5505 g, which was less than the force 1.7 g of virtual model control. The velocity planning buffer strategy was better to protect the robot.

Published: January 2023

Due to the substantial gross exchange fluxes with the atmosphere, the terrestrial carbon cycle plays a significant role in the global carbon budget. Drought commonly affects terrestrial carbon absorption negatively. Terrestrial biosphere models exhibit significant uncertainties in capturing the carbon flux response to drought, which have an impact on estimates of the global carbon budget. Through plant physiological processes, soil moisture tightly regulates the carbon cycle in the environment. Therefore, accurate observations of soil moisture may enhance the modeling of carbon fluxes in a model–data fusion framework. We employ the Carbon Cycle Data Assimilation System (CCDAS) to assimilate 36-year satellite-derived surface soil moisture observations in combination with flask samples of atmospheric CO2 concentrations. We find that, compared to the default model, the performance of optimized net ecosystem productivity (NEP) and gross primary productivity (GPP) has increased with the RMSEs reduced by 1.62 gC/m2/month and 10.84 gC/m2/month, which indicates the added value of the ESA-CCI soil moisture observations as a constraint on the terrestrial carbon cycle. Additionally, the combination of soil moisture and CO2 concentration in this study improves the representation of inter-annual variability of terrestrial carbon fluxes as well as the atmospheric CO2 growth rate. We thereby investigate the ability of the optimized GPP in responding to drought by comparing continentally aggregated GPP with the drought index. The assimilation of surface soil moisture has been shown to efficiently capture the influences of the sub-annual (≤9 months drought durations) and large-scale (e.g., regional to continental scales) droughts on GPP. This study highlights the significant potential of satellite soil moisture for constraining inter-annual models of the terrestrial biosphere’s carbon cycle and for illustrating how GPP responds to drought at a continental scale.

Authors: Poku-Agyemang Kwasi Nyarko , Reiterer Alexander
Published: January 2023

Due to increasing traffic on roads and railways, the maintenance of bridges is becoming more and more important. Building Information Modelling (BIM) provides the perfect basis to efficiently plan these maintenance activities. However, for historic bridges, which moreover require intensive maintenance, there is no BIM available. The demand to digitize these bridges is correspondingly high. Further, to the already existing measurement methods (laser scanning, photogrammetry, etc.), a novel workflow for the digitalization of bridges from 2D plans is presented. Based on image processing for corner detection, 3D point cloud reconstruction of parts and fusion of reconstructed parts can be used create a 3D object to scale. The point cloud can serve as a supplement to as-built laser scanning or camera data. The presented method was evaluated based on three bridges over the Dreisam river in Freiburg, Germany.

Published: January 2023

Landslides are catastrophic natural phenomena occurring as a consequence of climatic, tectonic, and human activities, sometimes combined among them. Mostly due to climate change effects, the frequency of occurrence of these events has quickly grown in recent years, with a consequent increase in related damage, both in terms of loss of human life and effects on the involved infrastructures. Therefore, implementing properly actions to mitigate consequences from slope instability is fundamental to reduce their impact on society. Satellite systems, thanks to the advantages offered by their global view and sampling repetition capability, have proven to be valid tools to be used for these activities in addition to traditional techniques based on in situ measurements. In this work, we propose an advanced multitemporal technique aimed at identifying and mapping landslides using satellite-derived land cover information. Data acquired by the Multispectral Instrument (MSI) sensor aboard the Copernicus Sentinel-2 platforms were used to investigate a landslide affecting Pomarico city (southern Italy) in January 2019. Results achieved indicate the capability of the proposed methodology in identifying, with a good trade-off between reliability and sensitivity, the area affected by the landslide not just immediately after the event, but also a few months later. The technique was implemented within the Google Earth Engine Platform, so that it is completely automatic and could be applied everywhere. Therefore, its potential for supporting mitigation activities of landslide risks is evident.

A P300-based speller can be used to control a home automation system via brain activity. Evaluation of the visual stimuli used in a P300-based speller is a common topic in the field of brain–computer interfaces (BCIs). The aim of the present work is to compare, using the usability approach, two types of stimuli that have provided high performance in previous studies. Twelve participants controlled a BCI under two conditions, which varied in terms of the type of stimulus employed: a red famous face surrounded by a white rectangle (RFW) and a range of neutral pictures (NPs). The usability approach included variables related to effectiveness (accuracy and information transfer rate), efficiency (stress and fatigue), and satisfaction (pleasantness and System Usability Scale and Affect Grid questionnaires). The results indicated that there were no significant differences in effectiveness, but the system that used NPs was reported as significantly more pleasant. Hence, since satisfaction variables should also be considered in systems that potential users are likely to employ regularly, the use of different NPs may be a more suitable option than the use of a single RFW for the development of a home automation system based on a visual P300-based speller.

Published: January 2023

Fault diagnosis and prognosis (FDP) tries to recognize and locate the faults from the captured sensory data, and also predict their failures in advance, which can greatly help to take appropriate actions for maintenance and avoid serious consequences in industrial systems. In recent years, deep learning methods are being widely introduced into FDP due to the powerful feature representation ability, and its rapid development is bringing new opportunities to the promotion of FDP. In order to facilitate the related research, we give a summary of recent advances in deep learning techniques for industrial FDP in this paper. Related concepts and formulations of FDP are firstly given. Seven commonly used deep learning architectures, especially the emerging generative adversarial network, transformer, and graph neural network, are reviewed. Finally, we give insights into the challenges in current applications of deep learning-based methods from four different aspects of imbalanced data, compound fault types, multimodal data fusion, and edge device implementation, and provide possible solutions, respectively. This paper tries to give a comprehensive guideline for further research into the problem of intelligent industrial FDP for the community.
Region Anomaly Detection via Spatial and Semantic Attributed Graph in Human Monitoring
Authors: Zhang Kang , Fadjrimiratno Muhammad Fikko , Suzuki Einoshin
Published: January 2023

This paper proposes a graph-based deep framework for detecting anomalous image regions in human monitoring. The most relevant previous methods, which adopt deep models to obtain salient regions with captions, focus on discovering anomalous single regions and anomalous region pairs. However, they cannot detect an anomaly involving more than two regions and have deficiencies in capturing interactions among humans and objects scattered in multiple regions. For instance, the region of a man making a phone call is normal when it is located close to a kitchen sink and a soap bottle, as they are in a resting area, but abnormal when close to a bookshelf and a notebook PC, as they are in a working area. To overcome this limitation, we propose a spatial and semantic attributed graph and develop a Spatial and Semantic Graph Auto-Encoder (SSGAE). Specifically, the proposed graph models the “context” of a region in an image by considering other regions with spatial relations, e.g., a man sitting on a chair is adjacent to a white desk, as well as other region captions with high semantic similarities, e.g., “a man in a kitchen” is semantically similar to “a white chair in the kitchen”. In this way, a region and its context are represented by a node and its neighbors, respectively, in the spatial and semantic attributed graph. Subsequently, SSGAE is devised to reconstruct the proposed graph to detect abnormal nodes. Extensive experimental results indicate that the AUC scores of SSGAE improve from 0.79 to 0.83, 0.83 to 0.87, and 0.91 to 0.93 compared with the best baselines on three real-world datasets.

Published: January 2023

In recent times, the existence of microplastics in the food chain has emerged as a physiological stressor and a multifactorial food safety issue, necessitating an immediate strategic perspective due to the associated human health and eco-toxicological risks. To the best of our knowledge, edible fruit crop facts have not yet been compiled, despite their presence in various food webs. Due to the risks associated with the public’s health when consuming products (e.g., fruit crops) that contain a high concentration of microplastic pollutants, a strategic approach to the emerging issue is essential. In this review, we discussed the possible sources of microplastics and their effect on horticultural crops, soil, and microorganisms; the techniques used to know the constitution of microplastics; the eco-toxicity of microplastics and their derivatives on horticultural crops; and suggested mitigation measures and public policies on control alternatives. This research aims to help environmentalists, biotechnologists, and policymakers understand the mechanism and dynamics of microplastics in soils and edible parts so that potential risks can be mitigated in advance.

Published: January 2023

The issues of the relationship between the innovative maturity of enterprises, the orientation of small- and medium-sized enterprises (SMEs) to the principles of sustainability, and the expansion of their participation in sustainable development with business efficiency are very important and interesting. In this case, it is important to find a good balance between a policy that focuses on sustainable development and businesses’ needs. This will help SME companies be as efficient as possible and have the least amount of impact on the environment. This is especially important for countries where small- and medium-sized businesses are the main driving force of the country’s economy. This research aims to examine how the conceptualizations of intellectual capital (e.g., relational capital, social capital, and structural capital) affect open innovation and sustainability-oriented initiatives to foster open sustainability innovation for small- and medium-sized businesses. Using structural equation modeling based on second-order factor analysis, survey data were collected from 481 SMEs in Thailand. Intellectual capital in SMEs enhances opportunity recognition in SMEs to develop open sustainability innovation, while sustainability-oriented initiatives and an open innovation strategy should be well-placed. SMBs and business policymakers should pay attention to the idea of intellectual capital in terms of socio-rational resources, in which open sustainability innovation projects could be developed through sustainable cooperation.

Published: January 2023

Building on the social support theory and the job demands-resources (JD-R) model, the current research explores the role of coworker task support on the perceived uncertainty, job stress, and emotional exhaustion of hospitality employees affected by the COVID-19 crisis. Moreover, this research investigates the moderating impact of supervisor support and family support on the relationship between perceived uncertainty and emotional exhaustion. The data were collected from 353 hospitality employees currently working in the hospitality industry in Pakistan. Partial least squares structural equation modeling (PLS-SEM) was employed using SmartPLS 3.3.3 software to examine the proposed hypotheses and to analyze the research model. The results point out that coworker task support has no significant relationship with emotional exhaustion. Furthermore, perceived uncertainty and job stress fully mediated the association between coworker task support and emotional exhaustion. Additionally, supervisor support and family support significantly moderated the association between perceived uncertainty and emotional exhaustion. This research contributes to the literature by expanding our knowledge of the role of social support in alleviating the perceived uncertainty, job stress, and emotional exhaustion of hospitality employees during the COVID-19 crisis. The theoretical and practical implications of the study are further discussed.

Published: January 2023

Enhancing agricultural water use efficiency can support Shaanxi Province’s transition to a sustainable agricultural economy. Using the data envelopment approach (DEA), we evaluated the water use efficiency in agriculture of various cities in the Shaanxi Province of China. Moran’s I and Dagum Gini coefficients were used to reveal spatial and temporal characteristics of agricultural water use efficiency. Furthermore, the geographically and temporally weighted regression (GTWR) model was used to investigate the effects of the agricultural economy, level of water-saving irrigation, cropping structure, environmental factors, and water supply structure on agricultural water use efficiency. The findings demonstrate that the average agricultural water use efficiency from 2011 to 2020 is low (0.796) in Shaanxi Province. Spatially there is considerable variation in water use efficiency between cities, with some highly efficient and some with very low efficiency. There is a strong negative spatial correlation between cities, with high efficiency cities tending to be adjacent to low efficiency cities. Moreover, the spatial differences in agricultural water use efficiency have increased over time, with the most significant increase within the northern region and between the north and central areas. Each influencing factor has a different impact from year to year and from city to city. Overall, the level of water-saving, the level of agricultural economics, the structure of the water supply, and environmental factors primarily have a negative influence. In contrast, the planting structure primarily has a favorable function. Therefore, to support the coordinated growth of agricultural water use efficiency, Shaanxi Province should improve its city-to-city cooperation and exchange of water use technology and experience, as well as develop differentiated water use measures appropriately for the development of each city according to local conditions.

Published: January 2023

The present manuscript describes a case study on the viewpoints of tourism stakeholders on the effect of waste management on a destination′s image. In particular, the study aims to analyze the problems that arose during the summer of 2018 in the touristic image of Corfu because of the waste management on the island. The qualitative method approach through interviews was used to collect the primary data of the survey; online sources were used to collect data to review similar cases. All the stakeholders agree that waste management during the summer of 2018 negatively affected the image of Corfu as a touristic destination. Moreover, based on the interviews′ findings, there is a lack of political will, infrastructure, and information provision from the local authorities on the island of Corfu. Interviews also indicated that an integrated solution to the problem of waste management on the island is the implementation of source separation in households and tourism-related firms with the support of the local authorities. The contribution of this paper is towards identifying the effect that waste management has on the image of a tourist destination. It is the first of its kind conducted in Greece and among the few reported in the literature focusing on the viewpoints of service providers.

The emergence of a monkeypox (MPOX) outbreak in 2022 represented the most recent recognizable public health emergency at a global level. Improving knowledge and attitude towards MPOX, particularly among healthcare workers (HCWs), can be a valuable approach in public health preventive efforts aiming to halt MPOX virus spread. The aim of the current study was to evaluate the knowledge and attitude of HCWs in Lebanon towards MPOX and to assess their conspiratorial attitude towards emerging virus infections (EVIs). The current study was based on a cross-sectional online survey distributed via Google Forms during September–December 2022 implementing a convenience sampling approach. The final study sample comprised a total of 646 HCWs: physicians (n = 171, 26.5%), pharmacists (n = 283, 43.8%), and nurses (n = 168, 26.0%), among others (n = 24, 3.7%). Variable defects in MPOX knowledge were detected, with a third of the participants having MPOX knowledge above the 75th percentile (n = 218, 33.7%). Satisfactory attitude towards MPOX (>75th percentile) was observed in less than a third of the participants (n = 198, 30.7%), while a quarter of the study sample endorsed conspiracy beliefs towards EVIs at a high level (>75th percentile, n = 164, 25.4%). Slightly more than two thirds of the participants agreed that MPOX vaccination should be used in disease prevention (n = 440, 68.1%). Better levels of MPOX knowledge and attitude were significantly associated with postgraduate education and older age. Physicians had significantly higher MPOX knowledge compared to other occupational categories. Less endorsement of conspiracies towards EVIs was significantly associated with male sex, occupation as a physician, and postgraduate education. Higher MPOX knowledge was associated with better attitude towards the disease. The current study showed unsatisfactory MPOX knowledge among Lebanese HCWs. Educational efforts can be valuable to improve the attitude towards the disease. Despite the relatively low level of embracing conspiracy beliefs regarding EVIs among HCWs in this study compared to previous studies, this area should be considered based on its potential impact on health-seeking behavior.

The Omicron variant is currently ravaging the world, raising serious concern globally. Monitoring genomic variations and determining their influence on biological features are critical for tracing its ongoing transmission and facilitating effective measures. Based on large-scale sequences from different continents, this study found that: (i) The genetic diversity of Omicron is much lower than that of the Delta variant. Still, eight deletions (Del 1–8) and 1 insertion, as well as 130 SNPs, were detected on the Omicron genomes, with two deletions (Del 3 and 4) and 38 SNPs commonly detected on all continents and exhibiting high-occurring frequencies. (ii) Four groups of tightly linked SNPs (linkage I–IV) were detected, among which linkage I, containing 38 SNPs, with 6 located in the RBD, increased its occurring frequency remarkably over time. (iii) The third codons of the Omicron shouldered the most mutation pressures, while the second codons presented the least flexibility. (iv) Four major mutants with amino acid substitutions in the RBD were detected, and further structural analysis suggested that the substitutions did not alter the viral receptor binding ability greatly. It was inferred that though the Omicron genome harbored great changes in antigenicity and remarkable ability to evade immunity, it was immune-pressure selected. This study tracked mutational signatures of Omicron variant and the potential biological significance of the SNPs, and the linkages await further functional verification.

Published: January 2023

In the Crimean Peninsula, there are several hypersaline lakes that have hydromineral and biological resources. However, they are under a significant anthropogenic load, which together with the climate change leads to negative consequences for the ecosystems. The aim of the work was to study the seasonal changes of physicochemical parameters of water (temperature, pH, oxygen content, salinity, redox potential Eh, optical density and transparency) and Artemia population in Saki Lake in 2022. For the daily fluctuations of temperature, O2, CH4 and CO2, a vertical temperature profile measuring system was installed at the boundaries of the air, water and bottom at a depth of 4 m and with a spatial discreteness of 0.2 m. The drive sensors for the content of gases assay in the air were installed. The increase in salinity and Eh in summer was accompanied by an increase in air and water temperature. Simultaneously, decreases in oxygen content and pH in brine have been observed. Artemia cysts were found throughout the year, nauplii were mostly available during spring and autumn, and the adults were shown in summer. The obtained results demonstrated the seasonal fluctuations in the hypersaline ecosystem within the ongoing climate change, and they can be used for the development of the optimal management of the mineral and biological resources of such water bodies.

Published: January 2023

Polychlorinated biphenyls (PCBs) are highly hazardous, persistent, and bioaccumulative substances that pose a threat to water quality in a number of locations, including the Beiluo River in Shaanxi Province, China. However, little is known about the contribution of PCBs to the Beiluo River. In this study, in order to look into the impact of sources on the water of the Beiluo River, the discovered PCB congeners in water were examined on a regional scale. The concentration of PCBs in water across Beiluo River was in the range from 0.065 to 1.92 ng L−1, and the average concentration was 0.37 ng L−1. The main PCB sources in the Beiluo River waterbody were found using positive matrix factorization (PMF). Source apportionment results indicated that the PCB pollution of the Beiluo River was mostly caused by industrial emissions, technical PCB mixtures, and coal and wood combustion. According to current ecological risk assessment guidelines, the PCB concentrations found in this study may have a negative impact on biological systems. Overall, the new information about the presence of several PCBs in the water of the Beiluo River justifies the need for urgent management actions, as well as long-term monitoring efforts, to protect ecosystems. Future investigations of these chemicals in China may use the conclusions of this first ecological risk level assessment on the PCB contamination in the waterbody of the Beiluo River as a guide.

Authors: Arnberger Arne , Eder Renate , Preisel Hemma
Published: January 2023

The assessment of visitor understanding and perceptions of natural landscapes and attitudes towards functions of a river national park is important for the acceptance and success of park management. The study asked 426 visitors to the Donau-Auen (Danube Floodplains) National Park in Eastern Austria about their affinity to the national park brand, their understanding of the river landscapes and attitudes towards the functions of a national park, and to what extent the visitors perceive the Danube Floodplains as a national park at all. The results show that a large proportion of respondents have some understanding of river national parks and their functions. Many respondents have a sense of being in a national park. However, for 60% of the respondents, the national park brand played almost no role in a visit to the national park. Visitors who have a higher affinity for the national park showed a stronger agreement with the functions of a national park. Those images from the Danube Floodplains National Park that depicted natural landscapes were judged by the majority of respondents to be typical of a river national park, but also meadows. Differences regarding the national park landscapes were not found among visitor affinity segments. Implications for environmental communication are presented.

Published: January 2023

A coagulation treatment is a separation technology widely used in industries as a pre-treatment step to remove the dissolved organic matter in wastewater. However, the type of coagulant, the optimized dose, and the treatment cost associated with various commercially employed coagulants must be investigated for the treatment of oil and gas produced water. In this study, five widely employed coagulants—ferric chloride, aluminum potassium sulphate, chitosan, sodium sulfide, and magnesium oxide—were tested for the treatment of actual complex oilfield-generated produced water. Water quality parameters such as the total suspended solids (TSS), total dissolved solids (TDS), turbidity, salinity, and pH were assessed for a better understanding of different coagulant activities against the produced water treatment. All the coagulants were efficient for the treatment of produced water. The findings of this study showed that ferric chloride led to the best removal of total solids (74.25%) of all water quality parameters, with treatment costs of USD 4 per m−3 of produced water. The results from this study contribute to the environmentally friendly, broader, and cost-effective application of a coagulation treatment to produced water.

Authors: Qiu Chengqun , Liu Xiaofu , Shen Yujie
Published: January 2023

A mechatronic inerter can simulate the equivalent mechanical network through the external electrical network and can be used in a wide range of mechanical device design applications. In this paper, we study the use of a mechatronic inerter to enhance vibration isolation in vehicle seat suspensions. Firstly, the vertical and pitch movements of the vehicle’s sprung mass and the vertical vibration of the seat are considered in a half vehicle model. Then, the mechatronic inerter is introduced and the external electrical network is presented. The particle swarm optimization algorithm was used to optimize the seat suspension layout parameters with different transfer function-orders. Numerical simulations under different speeds were performed, and the results show that the application of the used mechatronic inerter’s seat suspension vibration isolation performance outperforms passive suspension. In addition, with an increase in the external electrical network transfer function-order, the seat acceleration and pitch acceleration RMS values will be further reduced. The results of the study will contribute to a new approach to vehicle seat suspension design.

Published: January 2023

The article analyzes the structure of the range of flour-milling industry products sold in trade enterprises in Moscow and the Moscow Region. It is shown that there is both pure flour, which makes up the largest share in the assortment, and various flour-based mixtures (“for pan-cakes”, “for baking”, “for bread”, and “for general purposes”). It has been established that currently, Russia fully provides itself with flour and flour-based mixtures and is import-independent in this matter. The main focus is still on wheat flour of the highest grade, as it traditionally has the greatest and stable demand among consumers; however, today there is a significant expansion of the range of both flour without additives and various flour-based mixtures.

One of the problems of the feed industry is still unresolved issues in the field of the use of irreplaceable biologically active feed substances in feed for aquaculture facilities. The article discusses the experience of using astaxanthin in sterlet feeding. The study of the effect of astaxanthin on the morphophysiological state of fish, allows us to develop highly effective recipes for compound feeds for valuable species of aquaculture. Astaxanthin has a unique molecular structure that allows it to be both inside and outside the cell membrane at the same time. This is what provides better cell protection compared to beta-carotene and vitamin C. This powerful antioxidant has a huge impact on the work of all systems and overall health, but this practice has not affected valuable objects of aquaculture. The effect of astaxanthin on the physiological status of sturgeon fish has not been studied. It was found that the addition of astaxanthin — 20.0 and 40.0 mg/kg to the composition of production feeds allowed to increase productivity by 1.9 and 2.3 times, respectively. The indicators of energy metabolism also indicate a better accumulation of plastic substances in the fish of the experimental groups: hemoglobin in the variants with the addition of astaxanthin in the feed was 77.4 and 71.3 g/l, which is 17.6 and 8.4% higher than in the fish of the control group, in the same variants of the study, in comparison with the control sample, the level of total protein was significantly higher by 17.4 and 22.2% (p < 0.05). Thus, it can be said that the antioxidant astaxanthin provided more favorable trophic and biochemical conditions necessary, in particular, for the normal growth and development of fish.

An exploration of the maternity experiences of Wāhine Māori in their encounters with midwife Lead Maternity Carers
Authors:   , Burne-Vaughn Korina
Published: January 2023

The purpose of this research was to explore the maternity experiences of Māori women to understand the optimal conditions needed to provide women-centred relationships with midwife Lead Maternity Carers (LMC). The research focussed on the pregnancies, birth and motherhood experiences of Māori women and their relationships with LMC midwives. This research used kaupapa Māori theory and mana wāhine theory to explore the pūrākau (stories) of Māori women and their midwifery care to answer the research question “What are the maternity experiences of wāhine Māori in their encounters with Lead Maternity Care (LMC) midwives?” The purpose of this research project was to move beyond the deficit-focused research of Māori women that is prevalent in the literature. Ten wāhine Māori mothers participated in this research project: five first-time mothers and five mothers who had previously given birth to one or more babies. The age of the participants at the time of the study ranged from 21–38 years old. Online digital platforms replaced the planned kanohi kitea interviews and group wānanga (meeting or gathering) during COVID-19 level four restrictions. Thematic analysis was used to explore the pūrākau to reveal two main themes of whakamana wāhine (empowerment), whakawhānaungatanga (connections). Six subthemes were also identified tino rangatiratanga (self-determination), mana motuhake (autonomy), mātauranga Māori (knowledge), whānau (family), wawata (navigating relationships and wairua (spirituality). Wāhine Māori shared their stories of resilience and determination, their trust in their whānau and whakapapa, and spoke of how mātauranga Māori (knowledge) was critical to their care. LMC midwives were valued most highly when they provided support and encouragement for wāhine and their whānau to be self-determining and autonomous. This study contributes to the growing research being prompted by calls for improvements in midwifery education and practice. Furthermore, decolonising maternity spaces through revitalisation of pūrākau and reclamation of mātauranga Māori will influence change as seen from the perspective of wāhine Māori and their whānau.
