Abundant natural resources are the basis of urbanisation and industrialisation. Citizens are the key factor in promoting a sustainable supply of natural resources and the high-quality development of urban areas. This study focuses on the co-production behaviours of citizens regarding urban natural resource assets in the age of big data, and uses the latent Dirichlet allocation algorithm and the stepwise regression analysis method to evaluate citizens’ experiences and feelings related to the urban capitalisation of natural resources. Results show that, firstly, the machine learning algorithm based on natural language processing can effectively identify and deal with the demands of urban natural resource assets. Secondly, in the experience of urban natural resources, citizens pay more attention to the combination of history, culture, infrastructure and natural landscape. Unique natural resource can enhance citizens’ sense of participation. Finally, the scenery, entertainment and quality and value of urban natural resources are the influencing factors of citizens’ satisfaction.

Abstract Crustose coralline algae (Corallinophycideae) are red algae that produced calcium carbonate and are well recognized as foundation species in the epipelagic zone of the marine ecosystem. These algae induced settlement juvenile of coral by released chemical cues from bacterial communities on the surface of their colonies. Their extracellular calcium carbonate also can stabilize reef structure that influencing many invertebrate attaches and growth in the seabed. Crustose coralline algae (CCA) have obtained attention because of their distribution and health compromise to increasing seawater temperature, ocean acidification, and pollutant. As a cryptic species in the ecosystem, the presence of CCA recruit sometimes doesn’t have attention, especially on their capability to occupy the empty space. This study aimed to document coverage and number of CCA recruit in two different recruitment tile’s material. The highest CCA percentage of the cover was showed inside surface than others surface in all stations. Light intensity and low sedimentation were suggested as a key factor of success of high coverage. Overall, station higher CCA recruits have shown from Tiga Warna. Low sedimentation and protection from aerial exposure became the main reason for it. No significant difference number of CCA recruits between marble and sandstone in this study. Successful CCA recruitment in this study can give a wide picture that natural recruitment of coral and other reef biodiversity in Southern Malang might be will succeed because of the abundance of coralline algae that support their life history stage.

This study aimed to understand the impact of ethical codes on Saudi journalists’ perceptions toward mobile journalism (MOJO). Three major ethical dimensions were examined, including seeking truth, minimizing harm, and being accountable in news coverage. A survey link created with SurveyMonkey was transmitted via social media avenues, such as Twitter and WhatsApp, where Saudi journalists can complete the questionnaire and then share the link with other Saudi journalists. A total of 124 Saudi journalists were recruited by this snowball sampling approach, while the Codes of Ethics of Society of Professional Journalists was adapted as major measurements for three ethical dimensions, including seeking truth, minimizing harm, and being accountable. Results found that all three ethical dimensions of professional journalists generated significant influences on Saudi journalists’ perceptions toward MOJO. Specifically, minimizing harm was found as the most powerful factor that affected Saudi journalists’ perceptions toward MOJO, followed by being accountable and seeking truth, indicating that Saudi journalists who were more likely to seek truth, minimize harm, and be accountable would exhibit more positive perceptions toward MOJO. Although using smartphone as a journalistic tool was a key factor toward Saudi journalists’ MOJO perceptions, it was not as powerful as three ethical dimensions that affected their MOJO perceptions. Keywords: mobile journalism, codes of ethics, professional journalism, Saudi journalists

BackgroundInsomnia is a health problem that particularly affects people with schizophrenia. Its repercussions go beyond the disorder itself and affect many areas of life. The aim of the present study is to explore the clinical symptoms and consequences of insomnia in patients diagnosed with schizophrenic disorder and the perceptions of these patients regarding the care they receive.MethodsThe study takes a qualitative approach and uses semi-structured interviews to conduct a descriptive and interpretive analysis of 3 clinically different clusters of patients. These 3 clusters have been defined by using two-step cluster analysis based on the results of the ISI (Insomnia Severity Index) and EQ-5D scales (EuroQol-5D) and the presence of certain diagnostic symptoms in a sample of 170 patients. The final sample was 31 subjects. The analysis was based on a hermeneutic analysis of the patients' narratives regarding their experiences of insomnia.ResultsThe patients' narratives show differences in the intensity and experience of insomnia depending on the severity, as well as its impact on their quality of life. Insomnia has a huge emotional impact. Participants describe ruminations and obsessive thoughts as a key factor hindering falling asleep. Some of the everyday actions they perform encourage the chronicity of insomnia. The desired health response must include interventions that are effective, such as cognitive-behavioural therapy, and powerful, such as pharmacological solutions. Psychoeducation and advice on sleep hygiene are highly valued tools as preventive strategies.ConclusionsTo know the experience of users gives us a more comprehensive understanding of insomnia complexities and brings some new intervention strategies in patients with mental disorders. It is important that health professionals intervene preventively to stop the disorder from becoming chronic.

Europe stated the ambitious target of becoming carbon neutral by 2050 to combat climate change and meet the requirements imposed by the Paris Agreement, and renewable energy has proved to be a promising solution for the decarbonization of many sectors. Nonetheless, their aleatory nature leads to grid unbalances due to the difference between supply and demand. Storage solutions are needed, and electrofuels become a key factor in this context: they are fuels produced from electricity, which leads to carbon-neutral fuels if it originates from renewable sources. These can constitute a key solution to store the surplus energy and to decarbonize the so-called hard-to-abate sectors. Electrofuel production technologies have not yet been fully developed, and, in this context, extensive study of the state-of-the-art of existing projects can be very useful for researchers and developers. This work researches the European projects funded by the Horizon 2020 Programme regarding electrofuel production. The projects were analyzed in-depth using specific features, and the results were presented.

<p style="text-align: justify;">Coronavirus disease (COVID-19) preventive measures influenced teachers directly. The sudden shift to new teaching environment emerged unknown challenges influencing teachers’ work differently. As self-efficacy is a key factor of successful teaching, the goal of our study was to examine the relationship among teachers’ efficacy-related experiences, work satisfaction and workload during the pandemic. 769 teachers (55 men and 677 female, 32 undefined) completed the online version of the Norwegian Teacher Self-Efficacy Scale and the Relative Self-Efficacy Scale. Findings indicated significant positive correlation between job satisfaction and self-efficacy as well as job satisfaction and the sense of competency. Kruskal-Wallis Test proved higher level of self-efficacy among teachers with more experience in online teaching in the past. According to SEM analysis, job satisfaction is predicted by efficacy beliefs concerning the sense of competence, motivation, coping and conflict resolution. Our findings indicate that experience in online teaching methods can enhance self-efficacy, which contributes to higher job satisfaction.</p>

During the second wave of covid 19[SARS- Co V-] pandemic, there is a sudden increase in number of mucormycosis infection cases in India. The present study is an attempt to understand the presentation, course and outcome of rhinoorbital mucormycosis in a group of patients who reported to Ophtalmology and Otorhinolaryngology department of our Govt. District Hospital (secondary referral centre) for enhancing measures for prevention and management. Patients who reported to our Government district hospital with signs or symptoms suggestive of rhino orbital mucormycosis during May-June 2021 were included in the study with consent of ethical committee, patients and patient’s relatives. Total 17 cases were reported and followed. Clinical examination was done for all the patients. History of the presenting complaints and underlying illness with COVID -19 was elicited. Underlying comorbid status was recorded. Patients were followed as all of them were referred to higher centre for further management as per the guidelines issued by directorate medical and health services, rajasthan, Jaipur.13(76.4%) patients were from rural and 4 (23.5%) were from urban area. 11(64.7%) patients had RT-PCR +ve, 6 had RT-PCR _ve, 2 did not have RT-PCR report. 15(88.7%) patients had high blood sugar at presentation mean being 315.7mg%. 9 (52.9%) developed mucormycosis during their treatment for COVID in hospital. 8(47.05%) presented in OPD. 9 patients had treatment with inhalational Owhile 8 patients did not have treatment with O Death rate was high (70.5%) among our patients. Patients who survived (29.4%) had only initial symptoms and signs at presentation therefore could be managed earlier. None of our patient had vaccination for COVID. Our study was done at secondary referral centre, all the previous studies were done at tertiary referral centres; therefore it shows the course of disease mainly among rural population ; most of them presented very late and had poor outcomes. It shows the need of more awareness about COVID and mucormycosis among people especially in rural areas. High blood sugar either due to treatment with steroids or pre existing is a major risk factor for Rhino orbital mucormycosis. Being RT- PCR negative for COVID 19 does not rule out the associated possible complication of Rhino orbital mucormycosis. Early diagnosis and management remains the key factor for managing Rhino orbital mucormycosis.

The gut microbiota is a key factor in the correct development of the gastrointestinal immune system. Studies have found differences between the gut microbiota of newborns delivered by cesarean section compared to those vaginally delivered. Our objective was to evaluate the effect of ingestion of probiotics, prebiotics, or synbiotics during pregnancy and/or lactation on the development of the gut microbiota of the C-section newborns. We selected experimental studies in online databases from their inception to October 2021. Of the 83 records screened, 12 met the inclusion criteria. The probiotics used belonged to the genera Lactobacillus, Bifidobacterium, Propionibacterium, and Streptococcus, or a combination of those, with dosages varying between 2 × 106 and 9 × 1011 CFU per day, and were consumed during pregnancy and/or lactation. Probiotic strains were combined with galacto-oligosaccharides, fructo-oligosaccharides, or bovine milk-derived oligosaccharides in the synbiotic formulas. Probiotic, prebiotic, and synbiotic interventions led to beneficial gut microbiota in cesarean-delivered newborns, closer to that in vaginally delivered newborns, especially regarding Bifidobacterium colonization. This effect was more evident in breastfed infants. The studies indicate that this beneficial effect is achieved when the interventions begin soon after birth, especially the restoration of bifidobacterial population. Changes in the infant microbial ecosystem due to the interventions seem to continue after the end of the intervention in most of the studies. More interventional studies are needed to elucidate the optimal synbiotic combinations and the most effective strains and doses for achieving the optimal gut microbiota colonization of C-section newborns.

High-quality AlN film is a key factor affecting the performance of deep-ultraviolet optoelectronic devices. In this work, high-temperature annealing technology in a nitrogen atmosphere was used to improve the quality of AlN films with different polarities grown by magnetron sputtering. After annealing at 1400–1650 °C, the crystal quality of the AlN films was improved. However, there was a gap between the quality of non-polar and polar films. In addition, compared with the semi-polar film, the quality of the non-polar film was more easily improved by annealing. The anisotropy of both the semi-polar and non-polar films decreased with increasing annealing temperature. The results of Raman spectroscopy, scanning electron microscopy and X-ray photoelectron spectroscopy revealed that the annihilation of impurities and grain boundaries during the annealing process were responsible for the improvement of crystal quality and the differences between the films with different polarities.

Meso-crack evolution mechanism of shale is a key factor affecting the mechanical properties of shale. In order to explore evolution laws of cracks in shale during loading, a meso-crack monitoring system, loading test equipment and an automatic ultrasonic data acquisition system were set up. On this basis, a set of experimental apparatus simultaneous monitoring multi-parameters of shale micro-crack was designed, and destruction experiments of shale samples with different bedding angles were carried out to find out evolution characteristics of cracks. The results show the following: (1) The designed apparatus can monitor ultrasonic, mechanical and video information simultaneously of crack evolution in the entire process of shale destruction under load to provide information for analyzing acoustic and mechanical characteristic responses of crack propagation at key time nodes. (2) With an increase in load, shale will undergo four stages of destruction: crack initiation, propagation, penetration and overall failure. In the course of these stages, acoustic characteristics and mechanical characteristics are in good agreement, which proves the validity of predicting rock mechanical parameters with acoustic data. (3) During the loading process of shale, the main amplitude of acoustic wave is more sensitive than mechanical parameters to the change of rock cracks. Research results have important theoretical reference value for evaluating wall stability of shale gas horizontal well with ultrasonic data.
