Published: October 2022

ABSTRACT: The human skin encompasses a characteristic capacity to advance the self-regeneration after harm; this capacity can be compromised beneath particular conditions, like extensive skin loss, constant wounds, deep burns, non-healing ulcers and diabetes. Improper healing can lead the wound to enter in a constant state, which increments the chance of disease to chronic state; it affects the patient health and his/her quality of life. Due to growing concerns about unhealthy consequences of chemicals in the health care system, the interest towards natural and herbal substances has been growing every day. The plant Cassia auriculata is widely used medicinal plant in India and also popular in Indigenous system of medicines like Ayurveda and siddha. The collagen was successfully extracted from the Cattla Cattla fish scales using acid solubilizing collagen extraction method and the collagen was infused with plant extract of Cassia auriculata. The characterisation such as protein estimation (Lowry method), solubility (pH 1, 3, 5, 7, 9, 11 and 13), UV visible and FTIR was performed for collagen and phytochemical analysis (Alkaloids, Flavonoids, Saponins, Tannins, Phenol, Terpenoids, Glycosides and Steroids) anti-bacterial (E. coli and S. aureus) and anti-inflammatory test in different concentration (25mg, 50mg, 100mg / ml) was performed for the plant extracts and collagen infused with plant extracts. The result of the present study was confirmed that final product prepared using collagen with plant extract can be used to prepare the dressing material such as gels, ointments, bio-films, powdered flakes etc.

Toxoplasmosis caused by the protozoan parasite Toxoplasma gondii, the most prevalent disease worldwide. The infections in human are extremely dangerous if they happen during pregnancy because they may lead to miscarriage or congenital abnormalities, which predominantly affect the central nervous system. The main objective of current study was to identify the risk factors for toxoplasmosis and its prevalence among pregnant women in Mardan. The blood serum was tested using the ELISA and the latex agglutination test. Through interviews, sociodemographic and prospective risk factor data were gathered using a standardized questionnaire. Our findings, obtained from ELISA and latex agglutination tests, showed considerably higher toxoplasmosis rates of 23% and 11%, respectively. The geographic distribution of toxoplasma infection in district Mardan revealed a high prevalence in Shah Baig village through ELISA (28%) and latex test (12%) followed by Ibrahim Khan Killi (24%) and (16%), while lower cases were recorded through ELISA (20%) in Sheikh Yousaf Killi and Saleem Khan Killi. Compared to working women in the community (5.85 percent), the infection was more prevalent (18%) in non-occupational women/house wives. Moreover, it was also observed that abortion occurred to the woman who have been clinically diagnosed positive by ELISA and it reported 20% by ELISA and 11.4% by latex agglutination test. It was concluded that T. gondii infection were more prevalent in pregnant women of rural areas of Mardan as compared to the urban centers. Women and children were more vulnerable if they frequently interact with domestic animals and play in contaminated environment.

Published: October 2022

The development of Esomeprazole microspheres using enteric coated polymers, such as Eudragit L100, by antisolvent precipitation method has been the focus of recent research in order to achieve the best drug concentration along with improved stability and bioavailability without any adverse effects in an acidic environment. For the development of the Esomeprazole microsphere, a 32 factorial design was used, with polymer amount and rpm being the variables. According to the results of the factorial design investigation, it was found that polymer concentration has a substantial impact on drug release while stirring speed has a large impact on entrapment efficiency. Increased Eudragit L100 concentration caused the medication release to increase from 81.06 to 95.71%. The optimized formulation was then assessed for additional research on surface morphology, particle size, PDI, Zeta potential, percent entrapment efficiency, and in-vitro investigations drug release studies and stability of prepared formulation. According to the results of scanning electron microscopy for the optimised batch, developed microparticles with smooth surfaces and spherical shapes were found. 93.40% drug release and 70.63% drug entrapment efficiency were found in the optimised batch. As a result, the current study's findings indicated that microencapsulation had significant benefits for enhancing Esomeprazole's acid stability. By providing a delayed release effect for a duration of 10 hours and a higher patient compliance rate, developed microspheres were demonstrated to be efficient for protecting drugs in acidic media.

Authors: Abo-Haded Hany , Othman Muath , Alrohaili Ibrahim , Barzaiq Mohammad , Tukhi Mohammed , Olfat Mutasim
Published: October 2022

Objectives: The COVID-19 pandemic has affected the health care system, economic sector, and social life. Studies have examined the prevalence of mental disorders related to COVID-19 in the general population, but few studies have examined this among medical students. The aim of this study was to assess the level of depression and anxiety during the COVID-19 pandemic among medical students at Taibah University. Methods: A cross-sectional study was carried out among medical students at Taibah University. A web-based survey was distributed among medical students between January to July 2021. The survey includes Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) in addition to sociodemographic characteristics. Logistic regression analysis was used to assess the factors associated with anxiety and depression by calculating the odds ratios (ORs) with 95% confidence intervals (CIs). Results: A total of 218 students participated in the study with mean age of 22±1.7 years, and 59% male students. The mean depression score was 9±6 for all participants, while it was 7±5 for anxiety. Younger age groups have a higher mean of depression score than students above 23 years, and it was higher among female students than male students. For anxiety, female students also had a higher mean anxiety score (11±6) than male students (7±5). Senior year in medical school and those with previous history of COVID had a lower risk of depression, while for anxiety, the younger age group had a high level of anxiety compared to younger students. Conclusion: During the COVID-19 pandemic, high depression symptoms and anxiety levels were found among junior female medical students. The university's well-being center needs to support medical students to overcome challenges and difficulties during their junior years.

Published: October 2022

Aims

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

Methods

Any patient admitted to hospital with an open fracture between 1 June 2021 and 30 September 2021 was included, excluding phalanges and isolated hand injuries. Institutional information governance approval was obtained at the lead site and all data entered using Research Electronic Data Capture. Demographic details, injury, fracture classification, and patient dispersal were detailed.

Results

In total, 1,175 patients (median age 47 years (interquartile range (IQR) 29 to 65), 61.0% male (n = 717)) were admitted across 51 sites. A total of 546 patients (47.1%) were employed, 5.4% (n = 63) were diabetic, and 28.8% (n = 335) were smokers. In total, 29.0% of patients (n = 341) had more than one injury and 4.8% (n = 56) had two or more open fractures, while 51.3% of fractures (n = 637) occurred in the lower leg. Fractures sustained in vehicle incidents and collisions are common (38.8%; n = 455) and typically seen in younger patients. A simple fall (35.0%; n = 410) is common in older people. Overall, 69.8% (n = 786) of patients were admitted directly to an orthoplastic centre, 23.0% (n = 259) were transferred to an orthoplastic centre after initial management elsewhere, and 7.2% were managed outwith specialist units (n = 81).

Conclusion

This study describes the epidemiology of open fractures in the UK. For a decade, orthopaedic surgeons have been practicing in a guideline-driven, network system without understanding the patient features, injury characteristics, or dispersal processes of the wider population. This work will inform care pathways as the UK looks to the future of trauma networks and guidelines, and how to optimize care for patients with open fractures.

Variation of implant use in A1 and A2 trochanteric hip fractures
Authors: Baldock Thomas E. , Dixon Jan R. , Koubaesh Carol , Johansen Antony , Eardley William G. P.
Published: October 2022

Aims

Patients with A1 and A2 trochanteric hip fractures represent a substantial proportion of trauma caseload, and national guidelines recommend that sliding hip screws (SHS) should be used for these injuries. Despite this, intramedullary nails (IMNs) are routinely implanted in many hospitals, at extra cost and with unproven patient outcome benefit. We have used data from the National Hip Fracture Database (NHFD) to examine the use of SHS and IMN for A1 and A2 hip fractures at a national level, and to define the cost implications of management decisions that run counter to national guidelines.

Methods

We used the NHFD to identify all operations for fixation of trochanteric fractures in England and Wales between 1 January 2021 and 31 December 2021. A uniform price band from each of three hip fracture implant manufacturers was used to set cost implications alongside variation in implant use.

Results

We identified 18,156 A1 and A2 trochanteric hip fractures in 162 centres. Of these, 13,483 (74.3%) underwent SHS fixation, 2,352 (13.0%) were managed with short IMN, and 2,321 (12.8%) were managed with long IMN. Total cost of IMN added up to £1.89 million in 2021, and the clinical justification for this is unclear since rates of IMN use varied from 0% to 97% in different centres.

Conclusion

Most trochanteric hip fractures are managed with SHS, in keeping with national guidelines. There is considerable variance between hospitals for implant choice, despite the lack of evidence for clinical benefit and cost-effectiveness of more expensive nailing systems. This suggests either a lack of awareness of national guidelines or a choice not to follow them. We encourage provider units to reassess their practice if outwith the national norm. Funding bodies should examine implant use closely in this population to prevent resource waste at a time of considerable health austerity. Cite this article: Bone Jt Open 2022;3(10):741–745.
Caracterización de la vegetación en sitios con evidencias de antropización en Delta Frontal del Río Paraná
Authors: Bazylenko Andriy , Sirolli Horacio , Torrella Sebastián A.
Published: October 2022

Anthropization is one of the main structuring factors of plant communities at a global scale. In particular, in the Paraná River Frontal Delta there was a strong process of settlement and transformation of the territory by productive activities during the 20th century with a process of depopulation and partial abandonment of the productive plots in recent decades. The original vegetation of the Frontal Delta was made up of flooding grasslands (“Pajonales”), open woodlands (“Ceibales”) and closed riparian forest (“Montes Blancos”), replaced in large areas by crops that after their abandonment gave rise to a secondary succession process. In this work we aimed to characterize the flora and plant communities in plots with evidence of current or past anthropization in the Frontal Delta. A total of 202 sampling plots of 25 m2 were established in which the species of vascular plants were recorded and their coverage was estimated. Taken together, 167 taxa were recorded of which 81% were native. Through multivariate analysis, 15 communities with different physiognomy and degree of invasion were identified and characterized. Some of these presented a great similarity with the original communities of the region, others were similar to secondary communities described in the bibliography and novel situations were identified. The results highlight the great local richness of the vegetation and the great diversity of plant communities, highlighting the importance of the study area for conservation.

Authors: Moreno Parro Isabel , Ortiz Sánchez David , García Moreno Rosa , Gómez Rioja Rubén , Frutos Martínez Remedios , Álvarez-Escolá Cristina
Published: October 2022

Objetivos

El Cateterismo de Senos Petrosos Inferiores (CSSPPII) es una prueba útil para diferenciar entre el origen central y ectópico del síndrome de Cushing hormona adrenocorticotropa (ACTH)-dependiente. Presentamos el protocolo utilizado en nuestro centro y la evaluación de su rendimiento diagnóstico.

Métodos

Estudio retrospectivo de 28 pacientes sometidos a cateterismo de senos petrosos inferiores (CSSPPII) con estímulo por hormona liberadora de corticotropina (CRH). El procedimiento se realiza en un quirófano de neurorradiología en el que participa un equipo multidisciplinar de neurorradiólogos, endocrinólogos y analistas. Se cateterizan ambos senos petrosos y se obtiene una muestra periférica simultánea, en condiciones basales y a los 3,6 y 10 min tras estímulo. Se determinan ACTH y prolactina mediante inmunoquimioluminiscencia.

Resultados

Total de 19 pacientes con enfermedad de Cushing (EC) y 1 paciente con Cushing ectópico (CE) fueron confirmados. En todos los casos el CSSPPII orientó correctamente el diagnóstico, obteniéndose valores de sensibilidad y especificidad del 100%. En 8 pacientes no se alcanzó remisión postquirúrgica de la enfermedad. En el 84% de los cateterismos el valor de ratio más alto se alcanzó entre los 3 y 6 min postestímulo. Ratios y valores de ACTH en seno fueron superiores en los pacientes con confirmación histológica de EC. La ratio de prolactina permitió descartar un 28,6% de las muestras que habrían supuesto resultados discordantes respecto al resto de la exploración.

Conclusiones

En nuestra serie, el CSSPPII con estímulo por CRH ha demostrado ser un procedimiento seguro y eficaz. Se destaca la utilidad de la medición de prolactina como marcador de correcta cateterización y la importancia de la participación de un equipo multidisciplinar.

Published: October 2022

“Placenta Accreta Spectrum” (PAS) is a rare but serious pregnancy condition where the placenta abnormally adheres to the uterine wall and fails to spontaneously release after delivery. When it occurs, PAS is associated with high maternal morbidity and mortality — as PAS management can be particularly challenging. This two-part review summarizes current evidence in PAS management, identifies its most challenging aspects, and offers evidence-based recommendations to improve management strategies and PAS outcomes. The first part of this two-part review highlighted the general anesthetic approach, surgical and interventional management strategies, specialized “centers of excellence,” and multidisciplinary PAS treatment teams. The high rates of PAS morbidity and mortality are often provoked by PAS-associated coagulopathies and peripartal hemorrhage (PPH). Anesthesiologists need to be prepared for massive blood loss, transfusion, and to manage potential coagulopathies. In this second part of this two-part review, we specifically reviewed the current literature pertaining to hemostatic changes, blood loss, transfusion management, and postpartum venous thromboembolism prophylaxis in PAS patients. Taken together, the two parts of this review provide a comprehensive survey of challenging aspects in PAS management for anesthesiologists.
An analysis of the Q–A unities constructed by the interrogative pronoun какой
Authors: Ji Xiaojun
Published: October 2022

Language is a symbolic system consisting of the signifier and the signified. There is an asymmetrical binary correspondence between them, which is also widespread in Russian linguistics. There are two main types of interrogative sentence formed by the interrogative pronoun какой. Traditional lexicography and grammar have limitations in their understanding of какой and of the interrogative sentences it forms. The analysis of such syntactic phenomena should be included in the Q–A unity, which can be described in terms of argument structures, generic relations, deixis, relevant characteristics, properties, or attributes of objects, etc.

Published: October 2022

Objectives

Studies have shown that fibrinolysis activity is insufficient in COVID-19 patients. Plasminogen activator inhibitor-1 (PAI-1) is an important antifibrinolytic molecule that plays a key role in the fibrinolytic system. In our study; we aimed to evaluate serum PAI-1 and other biochemical parameters of COVID-19 patients in terms of disease course and mortality.

Methods

A total of 40 COVID-19 patients were hospitalized in the service and intensive care unit (ICU) of our hospital from October to December 2020 and 20 healthy volunteers were included in our study. The patients were grouped as those who transferred to the ICU from the service and transferred to service from the ICU. The first and second values of the same patients in both the service and the ICU were analyzed by SPSS.

Results

The PAI-1 levels of the patients in the ICU were significantly higher than the levels of the same patients in the service and the healthy control group (p<0.001). IL-6, ferritin, and D-dimer levels in the ICU of the same patients were significantly higher than the levels of service and healthy control group (p<0.001). A positive correlation was found between initial serum PAI-1 and D-dimer levels in patients hospitalized in the service (p=0.039) and initial serum ferritin and IL-6 levels in the ICU (p=0.031).

Conclusions

In our study, we found that PAI-1 levels increased significantly with the increase in mortality in COVID-19 patients.

Published: October 2022

Stressful life events are prevalent among justice-involved populations and are associated with sexual risk behaviors and partner communication regarding safe-sex practices. We describe patterns of stress exposure for heterosexual couples (where males are under community supervision) and how stress patterns are associated with sexual risk behaviors and communication (460 individuals; 230 couples). Latent class analysis identified patterns of stress. Multinominal logistic regression models identified associations between sex, race, ethnicity, and stress classes. Multilevel Poisson regression models described relationships between sexual risk behaviors and frequency of communication about condoms/HIV, and stress classes. We found four classes that differed by sex, race, and ethnicity and were associated with the number of sexual partners, condom use self-efficacy, discussing condoms with partner, and discussing HIV prevention with partner. Partner class was associated with the number of sexual partners. Findings inform future assessment/interventions for sexual health that consider patterns of stress and demographics.

This study examined substance use and sexual risk correlates of HIV testing among cisgender gay, bisexual, and other men (MSM) and transgender and nonbinary individuals (TSM) who have sex with men in Kazakhstan. We analyzed baseline data from an HIV prevention trial collected prior to intervention deployment (N = 304). Multivariable logistic regression analyses revealed that lifetime HIV testing was positively associated with poly-drug use (AOR = 4.4, 95% CI [2.0, 9.9]) and negatively with sexual risk (AOR = 0.4, 95% CI [0.2, 1.0]). Similarly, recent HIV testing was positively associated with polydrug use (AOR = 2.7, 95% CI [1.4, 5.2]) and negatively with sexual risk (AOR = 0.5, 95% CI [0.3, 0.9]). Current HIV testing was negatively associated with sexual risk (AOR = 0.6, 95% CI [0.3. 0.9]). Findings support the value of integrating drug treatment with HIV testing among MSM and TSM in Kazakhstan.
Are Borderline Personality Disorder Features Differentially Related to Pre-Incarceration Alcohol, Cannabis, Cocaine, and Opioid Dependence Among People Recently Incarcerated in Jail?
Authors: Loya Jennifer M. , Tangney June P. , Stuewig Jeffrey B.
Published: October 2022

Borderline personality disorder (BPD) and substance use disorders (SUDs) commonly co-occur across various settings. However, little research has examined how BPD features relate to specific types of SUDs. This study examined whether BPD features assessed shortly after incarceration were differentially related to symptoms of dependence on alcohol, cannabis, cocaine, and opioids experienced in the 12 months prior to incarceration among 510 people recently incarcerated in jail. Follow-up multigroup analyses evaluated whether gender or race moderated the relation of BPD features to the four SUDs. Using structural equational modeling, the relationships of BPD features were compared to each of the four preincarceration dependence symptoms. BPD features were significantly related to dependence on each of the four substances, but the link between BPD features and cocaine dependence was stronger than BPD's association with alcohol, cannabis, or opioid dependence. These findings generalized across men and women and across White and Black people.
Prefiguration and the Emergence of the Global Subject

Published: October 2022

The concept of prefiguration is discussed in the context of the potential, arguably imperative emergence of a global subject of sufficient power to overcome the global rule of capital, thereby opening a path to an ecosocialist transition to a global solar commons, terminating the political economy of capitalism on our planet. Prefigurative social formations and struggles are discussed, particularly in the global South, along with the potential role of ecosocialist parties that would coordinate the emergence of a global Subject.
Preconscious Attentional Bias to Rejection Facilitates Social Distancing for White Women in STEM Contexts
Authors: Chaney Kimberly E.
Published: October 2022

Science, technology, engineering, and mathematic (STEM) contexts are imbued with identity-threat cues for women, leading to disengagement. Research on the vigilance-avoidance hypothesis suggests that individuals rapidly detect threat cues and subsequently avoid detected threats to mitigate experiencing the negative implications associated with the threat. Integrating these lines of research, the present research examined White women’s preconscious attentional bias to rejection (PAB-R) and avoidance behavior (social distancing) in STEM contexts after exposure to identity-threat and identity-safety cues compared to neutral conditions. White women’s PAB-R was significantly greater in response to identity-threat cues and significantly decreased in response to identity-safety cues. Moreover, greater PAB-R led to greater social distancing (Studies 1b and 2). The present studies identified PAB-R as a novel, automatic process by which identity cues were associated with avoidance for women in STEM.
Too Much Information! The Interplay of Argument Quality and Subjective Difficulty in Attitude Judgment
Authors: Thongpaibool Thanaphat , Halberstadt Jamin
Published: October 2022

Paradoxically, people sometimes express weaker attitudes after generating more supporting arguments, a phenomenon usually attributed to subjective difficulty of generating them. We propose, however, that generating too many arguments compromises their evidentiary quality, which additionally explains attitude change. In Studies 1 and 2, Mechanical Turk participants generated 12 arguments supporting social issues. The results showed that, as more arguments were generated, the time of generating them increased, but the self-perceived argument quality declined. Although both correlated with attitudes, and each other, only argument quality uniquely predicted attitudes. Study 3 applied these insights to the “ease of retrieval paradigm,” showing that attitude change associated with generating 12 (versus 3) arguments was mediated by argument quality and its relationship with difficulty, although a main effect of argument number was not observed. The results show how reasoning involves an interplay of cognitive and metacognitive dynamics that produce self-generated attitude change in counterintuitive ways.

There are many translations of the term ambidexterity in Polish scientific literature. Some authors refer to this form of management as organisational two-handedness, universality, bilaterality, duality or bipolarity, while others leave the English name. The aim of the article is to compare theories of the phenomenon based on systematic literature review and linguistic meanings of Polish terms.
Circular business models in Swedish and Dutch cities
Authors:   Szkoła Główna Handlowa w Warszawie, Poland, Świrk Justyna
Published: October 2022

Contemporary problems related to the poor condition of our natural environment force changes in management models. The model that the economy has followed so far is a linear model - a highly consumption-based model that leads to an increased amount of waste and pollution, and consequently to not taking into account the interests of all stakeholders. As cities struggle with numerous problems (including a constantly growing population, pollution, demand for raw materials, etc.) they should change the way they are managed. The aim of the study is to identify which of them are most often used by these cities. The research questions asked in the article are: what is the role of the city as an authority in these models - is it an implementer or a recipient of circular models solutions? According to the current state of knowledge, is it possible to say that thanks to circular models used in cities the quality of life of residents is improving (from an environmental and social perspective)? The research method used was a review of professional literature (WoS and Scopus databases, as well as full-text databases), internet sources and reports. Three types of circular business models, in which Swedish and Dutch cities participate, were identified. The models that are used predominantly in cities in both Sweden and the Netherlands are models of sharing consumption. Cities as authorities assume different roles - they are both implementers and recipients of the models. It cannot be stated unequivocally that the introduction of circular business models in the current form has a positive effect on the quality of life in a city. Therefore, further research and experiments must be carried out, e.g. in the direction of expanding these models.

Published: October 2022

The decline of land quality has an impact on the decline of productivity which in turn reduces production. This kind of thing happened to rice fields in the research area of Seririt District. The objective of this study was to evaluate the rice field quality in Seririt District, Buleleng Regency, Bali Province. The study used a survey method to take soil samples, followed by laboratory analysis for each homogeneous land unit (HLU). The HLU was determined by overlapping soil type maps, slope maps, and utility maps. Parameters analysed were bulk density, texture, porosity, water content, organic C, pH, cation exchange capacity (CEC), base saturation (BS), nutrients (total N, available P, and available K), and biomass C. The results of the laboratory analysis were compared with the criteria for soil quality based on ten minimum data sets (MDS) for each HLU. The results showed that the soil quality at the study site is classified as very good in HLU I with a soil quality index (SQI) of 18. This HLU is located in Rangdu and Ringdikit villages, with an area of 125.15 ha. Good SQI was observed on HLUs II, III, IV, V, VII, and VIII, respectively, located in Banjar Asem, Lokapaksa, Pangkung Paruk, Bestala, Ume Anyar, Mayong, Joanyar, the SQI value of 22-25 is 2,321.49 ha with the limiting factors of total N, total P, texture, and bulk density. The suggested rice field management plan is the addition of organic, nitrogen, and phosphate fertilisers.

Hydrological phenomena on the scale of a watershed are complex and may never be understood holistically. One of the innovations in baseflow hydrological modelling is the analysis of the baseflow recession curve, generally expressed as the natural storage of river flows and containing valuable information about the properties and characteristics of natural aquifer storage. This study aims to model land use change and baseflow recession in the Wuryantoro watershed, Wonogiri Regency, Central Java Province. The research method uses an exponential model in which changes in the characteristics of a baseflow recession are a function of land use changes over a certain period. The calibration of the seven graphical models of land use change against the characteristics of the baseflow recession shows that the seven curves of the land use change graphic model have model coefficients and curve slopes that vary from gentle to steep. The slope of the gentle and steep curve describes the bottom flow deposits' condition over time. The state of water storage in the seven better graphical models is that the change of forest remains forest followed by the change of agriculture into the forest, forest into the settlement, change of agricultural land into the settlement, change of forest to agricultural land, settlement remains settlement and change of agricultural land remains agrarian land.

Understanding soil characteristics is important to determine the alternative strategies of land management, particularly those related to the scheme of soil and water conservation. This study investigated soil characteristics from four land covers around the coal mining concession area located in South Kalimantan. A soil survey was conducted using a purposive sampling method with three replicates in each land cover. Soil samples that were taken at depths of 0-10 cm, 11-20 cm, and 21-30 cm, were composited before being brought to the laboratory to quantify their characteristics, such as texture and organic carbon content. Data analysis was processed using a non-parametric test with a significant level of 5%. Comparison average of soil characteristics between land covers was evaluated using the Kruskal-Wallis test and followed by Nemenyi-test. Results found that soil characteristics from four land covers significantly differed in texture and organic carbon content. The highest sand fraction was noted in shrubs (67.23±0.86%), while the greatest silt fraction was recorded in plantation forests (29.71±2.84%). Compared to other land covers, the clay content in plantation forests and reclamation area was relatively equal by around 53-54%. On another side, The highest soil organic carbon was found in plantation forests with ranging of (4.44±0.14%) followed by natural forests (4.24±0.62%), shrubs (3.38±0.09%), and reclamation area (1.14±0.09%). These findings indicated there were high variations of soil characteristics from different land covers around the coal mining concession area. Therefore, it is recommended for managers to apply adaptive strategies in supporting soil conservation efforts based on the soil characteristics in each site.

The combination of water and land ecosystems as found in riparian areas offers valuable ecosystem resources, in dryland areas. The aim of this paper was to draw a management plan for the utilisation, and protection of the riparian forests or woodlands along the Black Volta River in Nandom Municipality. An exploratory research design was used together with quantitative and qualitative approaches. A survey of 75 respondents from 10 communities, 10 key informant interviews, and five focus group discussions in five communities were used to collect primary data. Satellite images for 2001 and 2014 were sourced from USGS site. The results revealed that riparian forest loss was 6.4% over 13 years. There was an increase in bare area by 10.6% over the same period. The study identified 49 plant resources, 14 wildlife resources, and 25 halieutic resources. A five-year management plan was developed with community participation; the implementation of which would engender sustainability of the riparian ecosystem.

Fertilisers, especially those containing NPK nutrients, have become a necessity in farming both rice fields and dry land. Most of the application of fertilisers is based on plant commodities and less based on the nature of the diversity of the soil or growing media. This study aimed to determine the balance of NPK nutrients and the nutrient elements that became the limiting factor in the rice and dryland maize cropping systems. The study was conducted at a rice field in Jember District and on dry land in Bogor District with maize plants. The fertiliser used is organic fertiliser. Nutrient balance is obtained by calculating the difference between the total input of nutrients N, P, and K given and the total output of nutrients N, P, and K transported by plants. The results showed that the combination of fertilizing treatment with biochar (50%), fish waste (25%), and chicken manure (25%) up to 10 t/ha on rice field soil at the experimental location in Jember had to limit factors for plant growth: low organic matter content, trace elements essential nutrients N and P are also low. Likewise, the combination of inorganic NPK fertiliser treatment with organic fertiliser up to 600 kg/ha on dry land in Bogor has not been able to improve its fertility status with limiting factors: low organic matter content, low N-total, and low exchangeable K.

The use of biochar for remediating heavy metal-polluted soils is still partial. Various methods of controlling soil pollution are currently being implemented by combining several methods. One of which is coating the biochar with humic acid to increase the effectiveness of nutrient uptake by plants. This study aimed to elucidate the effect of humic acid-coated biochar (HCB) on reducing Pb and Cu in the soil to improve plant growth. Treatments tested were combinations of two factors. The first factor was the dose of HCB, namely D0 = control (without HCB), D1 = 15 t HCB     ha-1, D2 = 30 t HCB ha-1, and D3 = 45 t HCB ha-1. The second factor was the type of plants, namely spinach (P1), water spinach (P2) and mustard green (P3). Twelve treatments were arranged in a randomised block design with three replications. The parameters observed were plant height, plant leaf area, plant stem diameter, and plant fresh weight. The results showed that the best plant growth was achieved at a dose of 30 t HCB ha-1. The mustard green had the highest Pb uptake (0.025 g pot-1), and the lowest Pb uptake (0.014 g pot-1) was observed for water spinach. The highest Cu uptake (0.443 g pot-1) was observed in water spinach, followed by spinach (0.282 g pot-1) and mustard green (0.143 g pot-1). In general, the amount of Pb reduced by plants ranged from 40.04 to 87.28%, and the amount of Cu by plants ranged from 8.63 to 40.23%.
The Effects of Parent Educational Expectations on the Competence Development of Rural Left-Behind Children: An Empirical Study Based on CEPS Data
Authors: Huang Heng
Published: October 2022

Based on data from the China Education Panel Survey (CEPS), this study conducted an empirical analysis of the effect of parent educational expectations on the competence development of rural left-behind children and the underlying mediating mechanism. The research findings reveal that rural left-behind children have far less developed competencies than their non-left-behind counterparts and that parent educational expectations significantly and positively influence the competence development of left-behind children. Specifically, parent academic expectations impose the greatest impact on academic results of left-behind children; parent expectations of child education levels have the widest effects on various competencies of left-behind children; Parent involvement and teacher support exert a chain mediating effect on the relationship between parent educational expectations and the competence development of rural left-behind children. The mediation effect of teacher support or the concurrence of teacher support and parent involvement remarkably promoted the competence development of rural left-behind children, while parent involvement alone results in masking effects, which impede the improvement of their competencies to some extent.
The Relationship between Mobile Phone Dependence and Mental Health among Adolescents: The Mediating Role of Academic Burnout and the Moderating Role of Coping Styles
Authors: Wan Jiaojiao
Published: October 2022

To investigate the relationships between adolescent mental health and mobile phone dependence (MPD), academic burnout, and coping styles as well as the underlying mechanisms, this study surveyed 1191 adolescents, using the mobile phone dependence indicator scale, adolescent academic burnout questionnaire, simplified coping style questionnaire, and SCI-90 self-report mental symptom inventory. The analysis results by structural equation modeling techniques are that: (i) MPD is a significant negative predictor of adolescent mental health; (ii) Academic burnout partially mediates the relationship between MPD and adolescent mental health; (iii) Negative coping styles moderate the second half of the mediating path; the mediating effect was more significant among adolescents with higher levels of negative coping than those with lower levels of negative coping. The findings of this study offer implications for the protection and promotion of adolescent mental health in the mobile internet era.
A Meta-analysis of the Relationships between Chinese Parenting Styles and Child Academic Achievement
Authors: Shi Zifu
Published: October 2022

This article aimed to examine the relationships between Chinese parenting styles and child academic achievement through a meta-analytical review. After literature screening, 54 studies and 793 independent effect sizes that met the inclusion criteria were incorporated into the analysis (n = 24630). According to the results of the study, positive parenting styles like “emotional warmth and understanding” had prominent beneficial effects on child academic achievement, whilst negative ones such as “punishment and harshness”, “overinvolvement and overprotection”, “preference for the subject”, “rejection and denial”) were significantly unfavorable for child academic performance. In addition, the relation between parental overinvolvement and overprotection and child academic achievement was moderated by parental roles. Children’s ages could moderate the relationships between parenting styles (except for overinvolvement and overprotection) and child academic results. The connection between parental preference for the subject and child academic achievement was moderated by disciplines. The effects of parents’ emotional warmth and understanding as well as overinvolvement and overprotection were moderated by times.

How to Remediate Heavy Metal Contamination in Soil?
Authors: Rahman Alexandre
Published: October 2022

The issue of heavy metal soil pollution has risen to the forefront. In addition to harming the pedosphere as a whole, soil pollution also has an impact on other significant sectors, such as air and water pollution. The two primary categories of pollution sources are natural sources and man-made sources. Mainly Hg, Cd, Pb, Cr, As, Zn, Cu, Ni, and other heavy metals are involved. The safety of agricultural products and the proper growth of people are of utmost importance. Thus, the origins of soil heavy metal pollution, the state of soil remediation research, and the development of soil heavy metal pollution remediation technology are all covered in this review. The technologies currently employed in soil heavy metal pollution remediation primarily include physical remediation, chemical restoration, bioremediation, agroecological restoration, and joint restoration. These methods are described, along with the conditions under which they can be used, application examples, and an analysis of their benefits and drawbacks. The most popular restoration technique is bioremediation.
Opportunities for further development of 3D-printed floating artificial reefs

Published: October 2022

This article sets out the potential benefits of combining floating structures with 3D-printed artificial reefs to increase sustainable development of artificial reefs. Traditional artificial reefs are often sited on the seabed (bottom-founded) and are limited to a narrow range of suitable deployment sites. By utilising floating structure technology to create floating artificial reefs, these ecological installations leverage the advantages of floating structures to create more conducive conditions for improved bio-diversity, aquacultural harvests, and coral growth. These advantages include the ability to sensitively deploy floating reefs in the photic zone of deeper waters or where there are soft seabed conditions, speed and flexibility in deployment, creative use of mooring systems to reduce the impact of climatic and navigational threats, and the use of reefs to reduce the impact of coastal erosion and increased urbanisation. This article then considers how floating artificial reefs offer biological and environmental advantages, with the potential to deploy these reefs under environmental offset policies. Importantly, the article considers how 3D-printing technology can produce topographical optimisation of the floating structure, and potentially increase the speed of coral coverage, diversity of fish species and reduced settlement predation. It concludes with identifying future research opportunities to realise the delivery of 3D-printed artificial reefs as part of floating offshore development projects or for environmental offset programs.
