Robot-assisted treatment of secondary epilepsy caused by parasitic infection: a case report

BackgroundCerebral sparganosis represents the most severe manifestation of sparganosis, with a relatively low global incidence. For cases of secondary epileptic seizures caused by sparganosis infection in the functional areas of the brain, what advanced neurosurgical techniques should be employed to precisely identify and excise the epileptic lesions in the deep functional areas of the brain, aiming to achieve maximal removal while minimising the risk of neurological deficits? This remains a current challenge for epilepsy surgeons.Case presentationA 24-year-old Chinese male was admitted to our hospital, presenting with a history of left limb twitching persisting for over a year. His main clinical symptoms presented twitching and numbness of his left limb without loss of consciousness. Under the premise of inappropriate anti-seizure treatment, recurrent epilepsy attacked persist. The patient's diagnosis was considered as “space-occupying lesions in the several lobes of brain, secondary epilepsy” after comprehensive assessment and discussion. And experts considered that the patient's space-occupying lesions in the right frontal and parietal lobes were highly suspected to be infected by parasites. This report delved into the application of neurosurgery robot-assisted frameless stereotaxic technology and intraoperative stereotactic electroencephalography (SEEG) monitoring technology to accurately locate and optimize removal of parasite-related epileptic lesions situated in functional areas of the brain. As a result, the patient had achieved seizure freedom, leaving no symptoms of neurological deficit.ConclusionsWith the highly integrated development of imaging technology, mechanical technology, computer control technology, and artificial intelligence, surgical robots are poised to play a larger role across various neurosurgical specialties in the future. Considering benefits for patients and the promising application of this technology, its utilization holds significant value.

Improved motor skills in autistic children after three weeks of neurologic music therapy via telehealth: a pilot study

BackgroundMany autistic children experience motor skill deficits which can impact other areas of functioning, and research on therapeutic interventions for motor skills in autism is in a preliminary stage. Music-based therapies have been used extensively to address motor skills in non-autistic populations. Though a handful of studies exist on the effects of music-based therapies for movement in autistic children, none have investigated the possibility of administering sessions via telehealth. This mixed-methods pilot study investigated whether nine Neurologic Music Therapy (NMT)® sessions via telehealth would improve motor and attention skills in autistic children.MethodsFive autistic children between five and 10 years of age participated in the study, with support from their caregivers. Motor skills were assessed using the Bruininks-Oseretsky Test of Motor Proficiency second edition, short form (BOT-2 SF), and a selective attention and sustained attention task were taken from the Test of Everyday Attention for Children, Second Edition (TEA-Ch2). Caregivers and the two neurologic music therapists involved in the study provided qualitative input about the perceived effectiveness of telehealth NMT for the children involved. Their responses were analyzed using qualitative content analysis. Caregivers also filled out a Sensory Profile 2 assessment prior to the onset of sessions so that each child’s sensory profile could be compared to their motor and attention results.ResultsStatistically significant improvements in motor skills were observed between pre-test assessment and a two-week follow-up assessment. Results from attention test scores were not significant. Caregivers and neurologic music therapists generally perceived sessions positively and noted the importance of having caregivers actively involved. When compared with individual progress on the BOT-2 SF assessment, sensory profile results revealed that children with fewer sensory sensitivities tended to improve the most on motor skills. The improvements in motor skills and positive caregiver and therapist views of telehealth indicate that NMT motor interventions administered via telehealth are a promising avenue of therapeutic support for movement skill development in autistic children.

Wheels in Motion: Exploring Challenges and Opportunities in Motorsports Management in Nepal

Nepal is a beautiful country with diverse terrain; Nepal's landscape consists of mainly three zones plain or terai, which occupy a quarter area of the country’s land this is almost surrounded by hills, which is around 40 per cent of the total area of the country. These hills are crowned by the majestic Himalayas including the world's highest peak Mount Sagarmatha (Mt.Everest )and other eight globally recognized mountains over 8000 meters. This unique backdrop of the country landscape gives enough trilling to motorsports events, including motorcycle, four-wheeler sports, and karting. The beautiful landscape of the country, where hill terrain is immediately accessible from the 5-10 km plain terai zone, (Plain Zone) along with beautiful scenes of mountains, lakes, rivers, and greenery, provides an ideal setting. The amazing fact is that when the riders reach the peak of the hills, not only the scenery will attract them but when they feel that the sky and stars are near to them and seem that they can be touched by their naked hand gives both pleasure, enjoyment and race emotion. We can assume Nepal as one of the best locations for the motorsports activities like touring. Additionally, the living cost is low, it is affordable for foreigners, and visitors, safety may be the other wonderful reason thus we can argue that Nepal is the best destination for motorsports tourism, presenting one of the main opportunities for the industry. To capitalize on the above potential, professionalism in event management is essential. Sometimes the traditional definitions of sports management may not work and redefining sports management may require however, traditional concerns of planning, budgeting, organizing, directing and ensuring profitability may need to be done for successful event execution in a country like Nepal. These are the functional areas that Sports managers perform. This article is the pathway to determine the challenges and opportunities in motorsports in Nepal. The findings are assumed to guide the Enthusiasts' club owners/managers and other concerned associates, they are engaged here in this article for their valuable inputs involving them in primary data collection. The Primary data are collected from clubs/ Motorsports Professionals national and international motorsports professionals to determine their major challenges. The importance of a disciplinary attitude among players is also highlighted. Primary data was collected through a questionnaire approach, and focus groups involving stakeholders such as clubs, federations, and provincial associations. The survey aimed to analyze the challenges and opportunities in motorsports management in Nepal. It has been observed that the Nepal Automobile Association (NASA-NEPAL) is the one and only Motorsports Federation, which is working in the development of motorsports in Nepal since its inception in 2008-09. It is affiliated with national and governmental regulating bodies like the Nepal Sports Council and international bodies like FIA, FIM, and CIK. Around 10 national clubs are associated with NASA Nepal and seven Provincial level associations are actively collaborating with the National Federation where approximately 200 players 100 marshals and 100 sports volunteers are primarily engaged in Nepal. During Primary data collection and the focus group discussion, it is also observed that this organized structure provides governance, safeguarding players, providing officiating training, and managing volunteers. In the primary stage of the Nepal motorsports fraternity, Nepalese youth or we can say players are drawn towards motorsports through their enthusiasm and they can be symbolized as self-taught players. Now the scenario has changed second stage Players are now playing the game. Apart from these systematic governing bodies, some of the motorsports clubs are now working in professional and business modules; secondly, Government investments in infrastructure, like racetracks, further enhance opportunities in the motorsports sector in Nepal. However, multiple challenges remain, and we have tried to identify the maximum by the research. Some of the heart-touching and crucial challenges may be financial security for players to compete nationally and internationally, along with the limited involvement of national automobile businesses in event sponsorship. The absence of automobile manufacturers poses challenges in fundraising, but collaborations with numerous other sponsors remain viable in the nation. In conclusion, Nepal's motorsports scene holds immense promise, contingent upon addressing financial challenges and securing support from stakeholders. This article offers insights into the challenges and opportunities in motorsports management in Nepal, contributing to its potential on the global stage.

Household Air Pollution in Three Urban Function Areas and Related Respiratory Health Effects

Household Air Pollution in Three Urban Function Areas and Related Respiratory Health Effects

Representational drift as a result of implicit regularization

Recent studies show that, even in constant environments, the tuning of single neurons changes over time in a variety of brain regions. This representational drift has been suggested to be a consequence of continuous learning under noise, but its properties are still not fully understood. To investigate the underlying mechanism, we trained an artificial network on a simplified navigational task. The network quickly reached a state of high performance, and many units exhibited spatial tuning. We then continued training the network and noticed that the activity became sparser with time. Initial learning was orders of magnitude faster than ensuing sparsification. This sparsification is consistent with recent results in machine learning, in which networks slowly move within their solution space until they reach a flat area of the loss function. We analyzed four datasets from different labs, all demonstrating that CA1 neurons become sparser and more spatially informative with exposure to the same environment. We conclude that learning is divided into three overlapping phases: (i) Fast familiarity with the environment; (ii) slow implicit regularization; and (iii) a steady state of null drift. The variability in drift dynamics opens the possibility of inferring learning algorithms from observations of drift statistics.

Analysis of spatio-temporal changes in net primary productivity and their driving factors in ecological functional areas of the Yellow River Basin

The Yellow River Basin (YRB) is an important region for both ecological and economic growth in China, and a healthy and stable ecological environment is fundamental to achieving high-quality development. Investigating the spatio-temporal changs of vegetation carbon sinks in the YRB is necessary to improve understanding of the regional carbon cycle. This study analyzed the YRB using the Google Earth Engine (GEE) platform. The basin was divided into sections based on ecological function regionalization schemes. We applied Theil-Sen median trend analysis and Spearman correlation analysis, along with the lasso regression model, to examine the NPP's temporal and spatial patterns and its driving factors in these regions. The objective was to examine the NPP’ s temporal and spatial patterns and its driving factors in these regions, identifying commonalities within regions and differences between regions, while analyzing in a targeted manner the lack of vegetation carbon sequestration in ecological areas. This study highlighted the importance of ecological engineering in ecological civilization and carbon neutrality, providing scientific theoretical support and a decision-making basis for the realization of carbon neutrality. The research results indicate significant upward trends (p<0.001) in both the average annual NPP (AANPP) growth rate (57.98%) and the total annual NPP (TANPP) growth rate (41.9%) in the YRB from 2001 to 2020. The multi-year average NPP (MYANPP) exhibit a spatial distribution with high values in the south and low values in the north. The spatial distribution of NPP exhibits notable spatial aggregation and heterogeneity, where regions demonstrating improvement trends constitute 93.01% of the area, and approximately 79.73% of this region displays low volatility. A high-value area is concentrated in the Agroecological Zone of the Fenwei Basin (I-11), the Loess Plateau Agriculture and Grassland Ecological Zone (I-12), and the Qinba Mountains Deciduous and Evergreen Broad-leaved Forest Ecological Zone (I-15), with significant spatial differences. Temperature, precipitation, and forests are the foremost elements affecting NPP in the YRB, exhibiting positive correlations. Conversely, farmland displays negative correlations. Overall, NPP shows an increasing trend in all ecological function areas, and the NPP of the YRB shows a trend of improvement as a whole, as the ecological environment of the YRB has improved significantly.

Effects of atmospheric deposition on heavy metal contamination in paddy field systems under different functional areas in ChangZhuTan, Hunan Province, China

In recent decades, the problem of heavy metal contamination in rice paddies has attracted widespread attention. However, most studies on heavy metal contamination in paddy fields are biased towards soil and/or rice plants, without taking atmospheric deposition into account. In this study, atmospheric deposition, paddy soil, and rice samples were collected from three functional areas (area proximity to factories, along the roadside, and suburban) in ChangZhuTan, Hunan Province. The pollution characterization, translocation, and health risk of heavy metals were reassessed. The findings revealed that Cd and As contamination in the study area's soils was more severe, with point exceedance rates reaching 70 % and 35.9 %, respectively. The highest concentrations of As, Ni, Cd, and Pb in atmospheric deposition were found along the roadside, with 1.42 μg/m2/day, 3.21 μg/m2/day, 0.34 μg/m2/day, and 8.28 μg/m2/day, respectively. In area proximity to factories, As and Ni in atmospheric deposition showed to be lowest, whereas Cd and Pb concentrations showed lowest in suburban areas. Furthermore, the accumulation of Cd and Pb in rice grains in regions proximity to factories was significantly higher than in other regions. The human health risk assessment indicated the health risk caused by rice intake in areas proximity to factories was the highest and requires attention, which was mainly due to Cd accumulation, with HQ value reached 3.19. Correlation tests indicate that atmospheric deposition has a positive effect on heavy metal enrichment in rice grains. Further Random Forest analysis revealed that the transport of heavy metals from atmospheric deposition to leaves and shells were important influencing factors for As, Cd, Ni and Mg accumulation in rice grain. Therefore, more attention should be paid to the effects of atmospheric deposition on the accumulation of heavy metals in paddy fields in order to maintain the production safety of crops.

Importance of the cervical paraspinal muscles in postoperative patient-reported outcomes and maintenance of sagittal alignment after anterior cervical discectomy and fusion.

The aim of this study was to investigate the influence of preoperatively assessed paraspinal muscle parameters on postoperative patient-reported outcomes and maintenance of cervical sagittal alignment after anterior cervical discectomy and fusion (ACDF). Patients with preoperative and postoperative standing cervical spine lateral radiographs and preoperative cervical MRI who underwent an ACDF between 2015 and 2018 were reviewed. Muscles from C3 to C7 were segmented into 4 functional groups: anterior, posteromedial, posterolateral, and sternocleidomastoid. The functional cross-sectional area and also the percent fat infiltration (FI) were calculated for all groups. Radiographic alignment parameters collected preoperatively and postoperatively included C2-7 lordosis and C2-7 sagittal vertical axis (SVA). Neck Disability Index (NDI) scores were recorded preoperatively and at 2 and 4-6 months postoperatively. To investigate the relationship between muscle parameters and postoperative changes in sagittal alignment, multivariable linear mixed models were used. Multivariable linear regression models were used to analyze the correlations between the changes in NDI scores and the muscles' FI. A total of 168 patients with NDI and 157 patients with sagittal alignment measurements with a median follow-up of 364 days were reviewed. The mixed models showed that a greater functional cross-sectional area of the posterolateral muscle group at each subaxial level and less FI at C4-6 were significantly associated with less progression of C2-7 SVA over time. Moreover, there was a significant correlation between greater FI of the posteromedial muscle group measured at the C7 level and less NDI improvement at 4-6 months after ACDF. The findings highlight the importance of preoperative assessment of the cervical paraspinal muscle morphology as a predictor for patient-reported outcomes and maintenance of C2-7 SVA after ACDF.

New technology, psychiatry, and the law: Panic, prudence, possibility

Throughout human history, all new technology has been met with surprise, anxiety, panic, and – eventually – prudent adoption of certain aspects of specific technological advances. This pattern is evident in the histories of most technologies, ranging from steam power in the nineteenth century, to television in the twentieth century, and – now – ‘artificial intelligence’ (AI) in the twenty-first century. Each generation believes that the technological advances of its era are quantitatively and qualitatively different to those of previous generations, but the underlying phenomenon is the same: the shock of the new, followed by more gradual adjustment to (and of) new technology. These concerns are apparent today in relation to AI, which reflects interesting but incremental advances on existing technologies, rather than stand-alone developments. The usual concerns with all technologies (e.g., that they will replace certain aspects of human function) are, perhaps, more concerning in fields such as mental capacity law, which often applies to people with impaired decision-making capacity who might be especially vulnerable to technologies which appear capable of encroaching disproportionately on decision-making or other areas of core human function. This paper approaches this topic from an historical standpoint, noting both previous technological panics in the past and the possibilities offered by AI today, provided it is approached in a proportionate, prudent, and person-centered way, underpinned by appropriate ethical guidance and active ethical awareness in clinical and legal practice.

High-fat diet induces sarcopenic obesity in natural aging rats through the gut–trimethylamine N-oxide–muscle axis

IntroductionThe lack of suitable animal models for sarcopenic obesity (SO) limits in-depth research into the disease. Emerging studies have demonstrated that gut dysbiosis is involved in the development of SO. As the importance of microbial metabolites is starting to unveil, it is necessary to comprehend the specific metabolites associated with gut microbiota and SO. ObjectivesWe aimed to investigate whether high-fat diet (HFD) causes SO in natural aging animal models and specific microbial metabolites that are involved in linking HFD and SO. MethodsYoung rats received HFD or control diet for 80 weeks, and obesity-related metabolic disorders and sarcopenia were measured. 16S rRNA sequencing and non-targeted and targeted metabolomics methods were used to detect fecal gut microbiota and serum metabolites. Gut barrier function was evaluated by intestinal barrier integrity and intestinal permeability. Trimethylamine N-oxide (TMAO) treatment was further conducted for verification. ResultsHFD resulted in body weight gain, dyslipidemia, impaired glucose tolerance, insulin resistance, and systemic inflammation in natural aging rats. HFD also caused decreases in muscle mass, strength, function, and fiber cross-sectional area and increase in muscle fatty infiltration in natural aging rats. 16S rRNA sequencing and nontargeted and targeted metabolomics analysis indicated that HFD contributed to gut dysbiosis, mainly characterized by increases in deleterious bacteria and TMAO. HFD destroyed intestinal barrier integrity and increased intestinal permeability, as evaluated by reducing levels of colonic mucin-2, tight junction proteins, goblet cells and elevating serum level of fluorescein isothiocyanate-dextran 4. Correlation analysis showed a positive association between TMAO and SO. In addition, TMAO treatment aggravated the development of SO in HFD-fed aged rats through regulating the ROS-AKT/mTOR signaling pathway. ConclusionHFD leads to SO in natural aging rats, partially through the gut–microbiota–TMAO–muscle axis.

Research on Irregular Warehouse Layout Based on Optimised Genetic Algorithm

Logistics is playing a significant role in supporting economic growth and material security during the epidemic period and it has been experiencing a rapid development in recent years. With the issues of personalisation and cost, the economy and society ask for higher requirements for logistics storage systems. The rational design of the functional area layout is an essential step to improve the operational efficiency of the logistics warehousing system. In reality, due to warehouse design and equipment application, there has been a gradual increase in irregular warehouses. By taking an irregular warehouse as an example, combining the operation status quo, this paper clarifies the functional area settings and constructs a 0–1 integer planning model based on the grid and systematic layout planning method with constraints, such as the unique functional attributes of the grid. We optimised the genetic algorithm based on the warehouse irregularity factor and the grids factor, and then solve it through MATLAB. Finally, by using the Flexsim software, simulation metrics were selected for evaluation, the method feasibility is verified.

Two common and distinct forms of variation in human functional brain networks.

The cortex has a characteristic layout with specialized functional areas forming distributed large-scale networks. However, substantial work shows striking variation in this organization across people, which relates to differences in behavior. While most previous work treats individual differences as linked to boundary shifts between the borders of regions, here we show that cortical 'variants' also occur at a distance from their typical position, forming ectopic intrusions. Both 'border' and 'ectopic' variants are common across individuals, but differ in their location, network associations, properties of subgroups of individuals, activations during tasks, and prediction of behavioral phenotypes. Border variants also track significantly more with shared genetics than ectopic variants, suggesting a closer link between ectopic variants and environmental influences. This work argues that these two dissociable forms of variation-border shifts and ectopic intrusions-must be separately accounted for in the analysis of individual differences in cortical systems across people.

Multiparametric cardiac magnetic resonance in patients with thalassemia intermedia: new insights from the E-MIOT network.

In a relatively large cohort of thalassemia intermedia (TI) patients, we systematically investigated myocardial iron overload (MIO), function, and replacement fibrosis using cardiac magnetic resonance (CMR), we assessed the clinical determinants of global heart T2* values, and we explored the association between multiparametric CMR findings and cardiac complications. We considered 254 beta-TI patients (43.14 ± 13.69years, 138 females) consecutively enrolled in the Extension-Myocardial Iron Overload in Thalassemia project. MIO was quantified by T2* technique and biventricular function and atrial areas by cine images. Macroscopic myocardial fibrosis was detected by late gadolinium enhancement technique. Compared to never/sporadically transfused patients, regularly transfused (RT)-TI patients exhibited significantly lower global heart T2* values, biventricular end-diastolic volume indexes, left ventricular mass index, and cardiac index. In RT-TI patients, age and serum ferritin levels were the strongest predictors of global heart T2* values. Independently from the transfusional state, cardiac T2* values were not associated with biventricular function. Of the 103 (40.6%) patients in whom the contrast medium was administrated, 27 (26.2%) had replacement myocardial fibrosis. Age, sex distribution, cardiac iron, and biventricular function parameters were comparable between patients without and without replacement myocardial fibrosis. Twenty-five (9.8%) patients had a history of cardiac complications (heart failure and arrhythmias). Increased age and replacement myocardial fibrosis emerged as significant risk markers for cardiac complications. In TI, regular transfusions are associated with less pronounced cardiac remodeling but increase the risk of MIO. Replacement myocardial fibrosis is a frequent finding associated with cardiac complications.

Fertigation-Driven Optimization of Growth Characters in Banana (Musa acuminate AAA) cv. Red Banana

The main aim of the study was to standardize the fertigation schedule and nutrient levels for growth enhancement in red banana. The study was conducted at the Department of Fruit Science College of Agriculture, Vellayani, Thiruvananthapuram during 2021-2023. The statistical design used was factorial Randomized Block Design replicated thrice with 12 plants per plot at a spacing of 2.1m x 2.1 m laid out with 12 treatment combinations of 4 different nutrient levels (60%, 80%, 100%and 120% RD of N and K) and 3 fertigation schedule (equal splits at weekly interval, at fortnightly interval, and according to the growth stage of the crop) and a control (KAU POP recommendation). Soil test based on fertilizer recommendation was derived based on KAU POP (200:200:400 g plant-1 year-1). Farm yard manure was applied as organic source at 10 kg plant-1) and P (200 g plant-1) to all treatments as basal. Water soluble fertilizers used included Urea as nitrogen source and Muriate of Potash as potassium source;. Data was collected from pseudo stem height, girth, number of leaves, leaf index, leaf area, days to shooting, time taken from shooting to harvest and crop duration. Data was analyzed using analysis of variance. The highest pseudostem height (310.53 cm) and girth (89.30 cm) was observed with the interactive effect of 120% of the recommended dose of N and K applied according to the crop growth stage) which was on par with F2S3(80% of the recommended dose of N and K applied according to the crop growth stage) at flowering stage. The total functional leaf area was maximum on F3S3 at the flowering (23.86 m2) and harvest stage (21.50 m2). Data on days to shooting (363 days), shoot to harvest (89 days) and total crop duration (452 days) in red banana showed that the interaction effect F2S3 has taken the least number of days. In conclusion the growth characters were observed to be better at 80% recommended dose of N and K with split application according to the growth stage of the crop .

High stability and selectivity of butterfly pea flower extract-NiAl LDH-based catalysts in the tetracycline degradation.

Layered double hydroxide (LDH) is an applicable material that can be modified in various ways. Modifications using natural extracts fulfill the principles of "green chemistry." The preparation of butterfly pea flower extract (BPE)-modified NiAl LDH was completed using the calcination and restacking method. The characteristics of the prepared composites were identified through analysis of functional groups, crystal phase, bandgap energy, surface area and surface morphology. Fourier transform-infrared (FT-IR) characterization revealed that the active group of the catalyst is -OH except for NiAl layered double oxide (LDO), which has the metal oxide-like functional groups. X-ray diffraction patterns expressed a typical layered material structure of NiAl LDH dan NiAl LDH-BPE, but not for NiAl LDO and NiAl LDO-BPE. Introducing BPE into NiAl LDH and NiAl LDO effectively decreased the bandgap energy and changed the surface morphology. The prepared catalysts were applied in a batch system with pH 5 to degrade tetracycline (TC). NiAl LDO demonstrated the highest activity as a catalyst in TC degradation, with a 93.61% degradation rate. In contrast, NiAl LDO-BPE demonstrated the highest structural stability in TC degradation and repeated use, with an initial degradation percentage of 82.58% and a fifth regeneration percentage of 71.4%.

Planning local centres in outer suburbs – The need for a proactive approach towards planning in post-socialist Poland

Chaotic post-socialist suburbs need retrofitting through planning a system of local centres. The paper is aimed at recognizing the orientation of recent suburban planning in Poland through a focus on centres and identifying conditions for and examples of a proactive approach to planning local centres. The hierarchy of centres and the set of functions assigned to them is important since it could prevent the dispersion of public facilities and strengthen the potential of higher-order centres. Documents subjected to analysis encompassed spatial policies of 27 suburban municipalities included in the Functional Area of Warsaw. The Polish spatial planning system neglects centres as a category of functional, economic, and social space, leaving municipalities complete freedom in planning them. The study proved that a system of local centres should become an urban planning standard since it helps municipalities locate public functions more reasonably. A vision of local centre development is rarely based on rational premises. The Polish case shows that in outer suburbs, a proactive approach to LC planning that involves designing a desired future and then inventing ways to create that future state is still a long way off.

THEORETICAL AND PRACTICAL DILEMMAS OF DEFINING THE CONCEPT OF INNOVATION

Innovations can take the form of implementing a modernised process, method or practical solutions in an enterprise, aimed at achieving specific benefits in the economic and social sphere. Innovations are related to specific changes in various functional areas of the organisation, including personnel. The cognitive purpose of the publication is to present the concept of innovation based on selected – national and foreign – literature on the subject. The goal of the research was to identify how innovations are defined in economic practice, especially in relation to the personnel area. The research problem was focused on obtaining an answer to the question regarding the perception of the concept of innovation in the personnel area. It was assumed that innovation in the personnel area is understood as the implementation of an improved process, method or solutions in the enactment of the personnel function. The empirical data was obtained using a survey technique with the use of a questionnaire. Empirical research was characterised by: subject, object, time and research space. The most important findings indicate that almost half of the respondents perceive innovation as a process, method or solution in the implementation of the personnel function. The conclusions from the research boil down to the statement that the Schumpeterian concept (promoting the understanding of innovation as the first application of a given invention in economy) turned out to be a rather distant concept for contemporary practitioners.

An important source of terrestrial microplastics‐atmospheric deposition: A microplastics survey based on Shaanxi, China

AbstractRecently, more and more studies have shown that the air may be an important source of microplastics (MPs) in the environment. But there is still a lack of research on MPs in the atmosphere. Here, we obtained the results of MPs concentration in atmospheric deposition in Shaanxi Province. Sampling was carried out for 6 months in 10 cities in Shaanxi Province and three different functional areas in Xi'an City. The results show that the MPs exist widely in the air of Shaanxi Province. The lowest MPs concentration of MPs was observed in Tongchuan (TC) and the highest in Xi'an (XA). Factors affecting the distribution of MPs in the atmosphere may include climate and urban population. Spectral analysis revealed that these MPs consisted of polyethylene terephthalate (PET), polyacrylonitrile (PAN), polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). PET, PAN, PE, and PP constituted the majority (90%) of the detected polymer types. The current research aims to contribute to the limited existing knowledge by examining the presence of MPs in all (wet and dry) atmospheric deposition in the urban environment of Shaanxi Province. The quantity, size, shape, and polymer type are evaluated, thereby improving our understanding of the characteristics of MPs deposition in urban environments.

Fine evaluation of ecological service functions in alpine and deep valley regions: A case study of the southeast Tibetan Plateau

Refined evaluation of ecosystem service functions in deep valleys in high mountain areas is an important means of precise protection of ecosystems. As the population continues to increase, human needs and demands on ecosystems continue to increase, and deep valleys in high mountain areas with good ecological integrity face the risk of development, it is urgent to balance protection and development and carry out precise protection of ecosystems. Based on the principles of typicality, specificity, feasibility and sustainability, this paper constructs an evaluation system for the ecosystem service function of the alpine deep valley area, consisting of 12 indicators from four aspects: Regulating functions, Provisioning functions, Supporting functions and Cultural functions. The Entropy Weight method was used to assign the weights of the relevant indicators in a hierarchical manner, and to complete the evaluation of the importance of ecosystem service functions and the importance zoning of the southeastern Tibetan Plateau. The results showed that: the importance of the ecosystem service functions of the Southeast Tibetan Plateau gradually decreases from southwest to northeast; the extremely important area is mainly distributed in the forest ecosystems with good originality and integrity in the south, accounting for 2.61% of the total area of the region, which needs to focus on ecological protection; the slightly important area is mainly distributed in the northern high altitude area with low vegetation cover and weak soil and water conservation capacity and grassland ecosystem, accounting for 58.89% of the total area of the region, which can be prioritized for development. The results of the study provide new ideas for precise protection of ecosystems and resolution of conflicts between ecological protection and development, as well as for the planning of functional areas for ecosystem services in deep valleys of high mountains, and also provide scientific references for regional sustainable development.
