Authors: Wang Yanyuan , Chen Junkai
Published: December 2024

The 2019 novel coronavirus pneumonia (COVID-19) epidemic has caused a great impact on the Chinese film market. In recent  years, the Chinese box office market has rebounded, but it has not recovered to the pre-epidemic level. Based on the box office data of 3791 Chinese movies from 2016 to 2023 provided by Maoyan Film, this paper proposes the concept of Film market Depression, identifies stopping points through stopping point analysis, and establishes a multiple regression model to explore the impact of competition. This study found that most stopping points occurred within two weeks of a movie's release, with new releases within three days likely to cause stopping points to reduce box office revenue, but high quality and popular movies suffered less revenue loss. This study innovatively analyzes the impact of dynamic competition on movie box office from a stopping point perspective. The research results show that the film market squeeze has a negative impact on the box office of the film, and the rational arrangement of films to reduce the negative impact of squeeze is helpful for the film to achieve better  box office performance. The research results are helpful to optimize the arrangement strategy and promote the development of the Chinese film market.

Research progress of carbon-based anode materials for lithium-ion batteries
Authors: He Ruihao
Published: December 2024

Lithium-ion batteries have received widespread attention for their high operating voltage, excellent energy density, long cycle life, low self-discharge rate, and environmental friendly characteristics. Currently, carbon-based anode materials are one of the most widely used choices for commercial applications. However, graphitic carbon materials suffer from low theoretical capacity, insufficient initial Coulombic efficiency, poor multiplicative performance, and graphite flake layer detachment due to interaction with electrolyte, and these defects limit their application scope. Although amorphous carbon materials perform better in terms of cycling and multiplicity performance, their large irreversible capacity is also a drawback that cannot be ignored. Therefore, the search for anode materials with better electrochemical performance has become one of the hotspots in current research. This paper summarizes the classification of carbon-based anode materials for lithium-ion batteries in detail, and reviews the recent research progress on the modification of carbon-based anode materials for lithium-ion batteries, including activated porosity, heterogeneous atom doping, and composite materials, etc., and looks forward to its future development direction.

Authors: He Haiyang , Gao Xinzhi , Huang Weiqiang , Xu Wenyan , Wang Yan
Published: December 2024

The carrying capacity of the geological environment to human activities is limited, and the maximum limit of this carrying capacity is the geological environment carrying capacity. It is necessary to scientifically understand the concept of geological environment carrying capacity from two dimensions: the geological environmental conditions (the carrier) and human activities (the load). With the entry into force of the document "Consent of the General Administration of Customs to Designation of the Port of Vladivostok, Russia as a Transit Port for Cross-Border Transportation of Domestic Trade Goods," the Dongning-Suifenhe region has ushered in new opportunities for development. How to ensure economic and social development while coordinating the relationship between geological environment and resource development, as well as ecological environmental protection, has become the key to the success of opening up and development. It is imperative to carry out the evaluation of geological environmental carrying capacity and function zoning in the study area. This paper evaluates the background carrying capacity and bearing state of the geological environment in the Dongning-Suifenhe region by using the hierarchical comprehensive index method. The evaluation has determined the degree of favorable geological environmental conditions as well as the degree of impact from human activities on the geological environment and resources. Based on this, geological environment function zoning is conducted, and recommendations on regional development and eco-environmental protection are presented.

Scene identification based on MobileNetV2
Authors: Liu Wenjun , Zhu Lin
Published: December 2024

Scene identification is a computer vision task, which aims to identify and classify environmental scenes in images or video frames. This technology plays a vital role in image retrieval, monitoring systems, and augmented reality. Convolutional neural networks (CNN) play a key role in scene recognition because CNN can capture and extract the features of the scene by simulating the processing mode of the human visual cortex, and realize efficient and accurate scene classification. However, the current scene recognition based on neural networks is generally expensive. In order to propose a solution to this problem, this paper chooses Mobilene ETV 2 lightweight convolutional neural network as the basic model of scene recognition on the premise of Transfer Learning. In this paper, a comparative experiment is carried out on the UC_Merced dataset. The experimental results show that the performance indexes of MobileNetV2-the Accuracy of mobilenetv2 reach 93.57%, the F1_score reaches 93.50%, and the Kappa reaches 93.25%. All of them are better than other neural networks.

Authors: Chen Xinyu
Published: December 2024

Poa pratensis, commonly known as Kentucky bluegrass, is a cool-season turfgrass widely used in the world. It has excellent stress resistance and adaptability. However, Poa Pratensis is vulnerable to various diseases, which affect its growth and landscape effect. This paper reviews the primary research on Poa poa diseases in recent years, aiming to summarize the occurrence characteristics, pathogenic bacteria, and pathogenic mechanisms of common diseases and to evaluate the existing control measures. The common diseases of bluegrass include brown spot (Rhizoctonia solani), Pythium Root Rot (Pythium spp.), Rust Disease (Puccinia spp.), Powdery Mildew (Blumeria graminis), Fusarium blight (Fusarium spp.), and summer patch (Magnaporthe poae). The occurrence of these diseases is closely related to environmental conditions and management measures. Although chemical control measures have proven effective in controlling the disease, their long-term use may lead to environmental pollution and drug resistance. Biological control and integrated management strategies have gradually become a research hotspot, showing good application prospects. This review provided theoretical support and reference for future research to explore the ecological mechanism of the disease further, develop more environmentally friendly and efficient control measures, and ensure the healthy growth of Poa grass.

Authors: Macuda Małgorzata , Zieniuk Paweł
Published: December 2024

Purpose: The paper presents the practices of voluntary assurance on sustainability information disclosure in European companies before the implementation of the Corporate Sustainability Reporting Directive (CSRD). It attempts to determine the factors that influence decisions related to verifying independent reports. Methodology/approach: The research sample comprises 576 European companies whose sustainability reports, prepared according to the GRI guidelines, were available from the GRI Sustainability Disclosure Database. Logit regression was used to determine factors that influence companies' decisions on voluntary assurance. Findings: There is a statistically significant positive relationship between a company's decision to pursue voluntary assurance on sustainability reporting and (1) company-specific characteristics, (2) previous experience with sustainability reporting, (3) selected sustainability reporting practices (e.g., reporting on Sustainable Development Goals) and (4) country-specific factors (e.g., the strength of auditing standards in the company's operating environment). Research limitations/implications: In light of CSRD requirements, which introduced mandatory limited assurance from 2024, transitioning to reasonable assurance over time, the study provides valuable insights into the extent to which companies use assurance services. These findings may be useful for practitioners and standards setters. Originality/value: The paper adds to the understanding of the choices made by individual companies regarding the assurance of sustainability information disclosure. The study considers different influencing factors and examines a time horizon that precedes the implementation of mandatory assurance.

The implementation of Sámi teacher education is based on the values ​​of Sámi education. The starting point of this education is the changing needs of the Sámi community. The Sámi concepts of learning, teaching methods and traditional education have developed in the Sámi community over the centuries and have been the subject of active research in recent decades. Pre-service teachers are guided as part of the expertise of Sámi pedagogy by using methods that they are supported to employ in their own work. However, little research has been conducted on the implementation of Sámi teacher education. In this article, we, three Sámi teacher educators, discuss how we perceive Sámi education and educational values. We use examples from our experiences with our families and the schools we have attended and incorporate these into our work as Sámi teacher educators. We also present teacher educators’ perceptions of the university pedagogical approach in Sámi teacher education. The discussion focuses on the work of creating and developing a dynamic learning environment. As a starting point, we present pedagogical approaches in Sámi teacher education, developed over the years at Sámi allaskuvla.

Kutokana na matokeo haya, waandaaji na wachapishaji wa kamusi wanashauriwa kuweka jitihada za kuyaepuka makosa ya aina hii. Hili litahakikisha kuwa ujumbe wa kamusi unawafikia watumiaji kama ulivyokusudiwa na kuwaepushia athari zilizotajwa.
Reforestation for Mitigation and Adaptation to Climate Change in North-Eastern Highlands of Tanzania: Beyond Carbon Sequestration
Authors: John Raphael Leonia , Mromba Clement
Published: December 2024

Reforestation has been emphasized as an authoritative intervention for climate change mitigation because of its carbon storage potential. Reforestation can also play other frequently overlooked, but important, roles in helping society and ecosystems adapt to climate variability and change. For example, reforestation can amend climate-associated impacts of altered hydrological cycles in watersheds, protect coastal areas from increased storms, and provide habitat to reduce the probability of extinction of species under a changing climate. Consequently, reforestation should be managed with both adaptation and mitigation objectives in mind, so as to maximize synergies among these diverse roles, and to avoid trade-offs in which the achievement of one goal is detrimental to another. Management of increased forest cover must also incorporate measures for reducing the direct and indirect impacts of changing climate on reforestation itself. Here, the focus is on ‘climate-smart reforestation’, defined as reforesting for climate change mitigation and adaptation, while ensuring that the direct and indirect impacts of climate change on reforestation are anticipated and minimized.
The Influence of Social Networks on the Livelihoods of Urban Refugees in Dar es Salaam, Tanzania
Authors: Daniel Namkesa Faraja
Published: December 2024

This study examined the influence of social networks in enhancing the livelihoods of urban refugees in Dar es Salaam City, Tanzania. It focused on the key actors within the social networks of urban refugees, as well as the effectiveness of these networks on enhancing the livelihoods of refugees in Dar es Salaam City. Social network and actor network theories guided this study. Using a qualitative approach, data was collected through focus group discussions and document reviews. Four focus groups were organized, involving Burundian men, Congolese men, Congolese women, and a mixed group of Congolese and Burundian youth. Thematic analysis was employed to identify key themes and patterns in the data. Findings revealed that urban refugees rely on various social networks, both formal and informal, ranging from government to non-government organizations, international organizations, families, and friends. Actors in the formal networks included Dignity Kwanza, Tanganyika Christian Refugee Services (TCRS), Relief to Development Society (REDESO), Church World Services (CWS), UNHCR, and the Refugee Department under the Ministry of Home Affairs, which provides training, financial, and legal support. In addition, informal networks that refugees have established include family and friendship within the host community, offering critical moral, social, and material support. The results suggest that, while formal network support in the form of training has not significantly improved the livelihoods of refugees due to policy restrictions, informal networks, specifically those made up of family and friendship ties, were effective in enhancing the livelihoods of these refugees in Dar es Salaam. The study recommends tailoring training initiatives for refugees within Tanzania’s refugee policy context, to optimize their impact on their livelihoods.

Published: December 2024

Stroke is a neurological disorder that can lead to disability and significant stress, particularly among young stroke survivors. Quantum Touch therapy, an alternative energy-based therapy, may hold potential for stress management. Evaluate the effectiveness of Quantum Touch therapy in reducing stress levels among young stroke survivors. This quasi-experimental study used purposive sampling, involving 76 young stroke survivors (aged 18-50), who were randomly assigned to either the intervention group (38 participants), receiving Quantum Touch therapy, or the control group (38 participants), receiving only standard care. Therapy sessions were conducted six times per week, each lasting 30 minutes, over the study period from March 1 to May 1, 2024. Stress levels were measured using the Depression Anxiety Stress Scales-42 questionnaire before and after the intervention. Analysis showed that the intervention group experienced a significant reduction in stress levels after undergoing Quantum Touch therapy, with an average stress score change of 3.29 (p < 0.001), while the control group showed no significant change (p = 1.000). The statistical analysis also highlighted a substantial effect size in the intervention group, emphasizing the quantifiable impact observed. This study suggests that Quantum Touch therapy has significant potential in reducing stress levels among young stroke survivors. The therapy contributes to stress reduction by restoring energetic balance, leading to deep relaxation and decreased anxiety and muscle tension. The findings support the inclusion of Quantum Touch therapy as a complementary approach in post-stroke rehabilitation, offering measurable benefits in stress management for young stroke survivors

Outcome Quality and Treatment Efficacy of Early Class II elastics compared to Late Class II elastics: A Retrospective Clinical Investigation
Authors: Sayahpour Babak , Eslami Sara , Guderian Robert , Kopp Stefan , Stuhlfelder Jakob , Plein Nicolas , Grassia Vincenzo , Nucci Ludovica
Published: December 2024

Introduction: Class II elastics are widely used treatment modalities in correction of class II malocclusion. Class II elastics are traditionally used in combination with multibracket appliances after completion of the initial leveling phase.  The use of early short and light class II elastics on initial leveling wires has been advocated to reduce the treatment time and increase the treatment efficiency. However, there is a lack of sufficient evidence in the literature. Therefore, the aim of this retrospective study was to investigate the outcome quality and treatment efficiency of early class II elastics compared to late class II elastics using the PAR index. Materials and Methods: Patient records from September 2005 until April 2017 in the archive of the university of Frankfurt have been sighted to generate data for this retrospective study. Patients with class II malocclusion undergoing a treatment with multibracket appliance after their peak of growth were included in the study. 16 Patients were included in the group IEA (early class II elastics) and 21 were allocated to the group IEL (late class II elastics). The peer assessment rating index (PAR) was used to assess the treatment outcome in each group. Results: Both early and late class II elastics showed great improvement of the occlusal traits in the patients. However, the treatment duration was significantly shorter in group IEA, showing the higher efficiency of early class II elastics. Conclusion: Incorporation of early class II elastics on the initial leveling arch wires can increase the treatment efficiency without compromising the occlusal outcome of the treatment. The authors recommend the use of short and light elastics in the initial stages of the treatment. Since early class II elastics were first described scientifically in our study, further studies and especially prospective ones should be performed.

Authors: Kallinen Kati
Published: December 2024

Artikkelissa tutkitaan, millaisia kokemuksia perhehoitoon sijoitetuilla lapsilla on kodista henkilökohtaisen elämän ja kuulumistyön käsitteiden näkökulmista. Aineiston muodostavat 16:n perhehoitolapsen haastattelut, jotka toteutettiin heidän sijaiskodeissaan. Tutkimuksessa on huomioitu eettiset kysymykset ja tutkimusaiheen sensitiivisyys. Perhehoitolasten kokemukset kodista jäsentyivät kolmeen teemaan: kodin monipaikkaisuus ja ajallisuus, kodin turvallisuus ja turvattomuus sekä kodin muutokset ja pysyvyys. Kokonaisuudessaan teemat tekevät näkyväksi kodin merkityksellisyyttä, haavoittuvuutta ja ristiriitaisuutta perhehoitoon sijoitettujen lasten elämässä. Sijoitettujen lasten hyvinvoinnin edistämiseksi on mahdollista ja tärkeää tutkia lasten kokemuksia kodista henkilökohtaisen elämän ja kuulumistyön käsitteiden avulla. Ammattilaisten on tärkeää tunnistaa ja huomioida kodin moniulotteinen merkitys sijoitettujen lasten ja myös nuorten hyvinvoinnille heidän henkilökohtaisessa elämässään ja kuulumistyön näkökulmasta.

The meaningfulness, vulnerability and contradictions of home in foster children’s lives Kati KallinenThe Finnish Journal of Youth Research(Nuorisotutkimus) Vol 42 (4), 19–32
This article explores foster children’s experiences of home through the concepts of personal life and belonging work. The data consist of interviews with 16 foster children, conducted in their family foster homes. Ethical issues and the sensitivity of the topic were taken into account. The analysis revealed three key themes in foster children’s experiences of home: the multi-faceted and temporal nature of home, the safety and insecurity of home, and the changes and stability of home. Collectively, these themes address the meaningfulness, vulnerability and contradictions of home in foster children’s lives. To improve the wellbeing of foster children, it is important to study their experiences of home through the concepts of personal life and belonging work. It is also important for professionals to recognize and pay attention to the multidimensional meaning of home for the well-being of children and young people in foster care.

Impacts of Casson Fluid Flow and Heat Source/Sink in an Oscillating Plate with Unequal Wall Temperature
Authors: Ojemeri Godwin , Abubakar Jamilu
Published: December 2024

Casson fluid is commonly used in many notable technological and industrial properties, such as synthetic lubricants, specific oil paints, biological fluids, diverse polymer solutions to mention few. The Casson fluid is considered to be one of the most prominent types of fluids within the category of non-Newtonian substances. The impact of Casson fluid impact on hydromagnetic oscillatory flow along a permeable plate immersed in porous medium is investigated in the optically thin thermal radiation regime. The solutions of the dimensionless equations have been obtained. In view of the assumed oscillatory pressure gradient, the resultant linear partial differential equations were reduced to a boundary-valued-problem where the unsteady flow is superimposed on the mean steady flow. The influence of controlling parameters dictating the flow behaviour have been demonstrated graphically and explained thoroughly. It is revealed from the computational analysis that the function of Casson fluid parameter is to diminish the fluid velocity. Additionally, the skin friction is increased at both walls as the suction/injection parameter is increased. Interestingly, the results obtained for limiting case in this research is consistent with previous literature, thereby establishing the accuracy and validity of the current investigation.
Enhanced Robust Estimators for Population Mean Accounting for Non-Response and Measurement Error
Authors: Joseph O.A. , Shehu B. A.
Published: December 2024

Estimators play a crucial role in statistics, quality assurance, and survey methodology, which estimate key population characteristics like: the mean, variance, and standard deviation based on sample values. However, data collection in medical and social sciences often faces significant challenges due to non-response and measurement errors, which complicate the data compilation, computation, and estimation processes. This study proposes a robust class of estimators that address these challenges by incorporating call-back and imputation schemes and parameters accounting for measurement errors, thereby enhancing estimator efficiency despite the adverse effects of non-response and measurement errors. The properties of these proposed estimators, including bias and mean square errors (MSEs), were derived using a second-degree Taylor series approximation, and a consistency test was performed. The research also established the conditions under which the proposed estimators are more efficient than existing ones. An empirical study utilizing simulated data from distributions—normal, exponential, chi-square, uniform, gamma, and Poisson—demonstrated that the modified estimators under the imputation scheme are significantly more efficient and reliable than the existing alternatives. Consequently, these modified classes of estimators are recommended for practical application, particularly in scenarios involving non-response and measurement errors during data analysis and estimation.

Point Cloud Upsampling Network Incorporating Dynamic Graph Convolution and Multi-Head Attention
Authors: Yang Xiaoping , Chen Fei , Li Zhenhua , Liu Guanghui
Published: December 2024

To address the problems that graph convolution uses a fixed graph structure, fails to capture dynamic or changing graph structure information, and is prone to bias by employing the same attention. A point-cloud upsampling network (DGCMSA-PU) incorporating Dynamic Graph Convolutional (DGCNN) and Multi-head Self-Attention (MHSA) is designed. DGCNN is utilised for up-sampling and a MHSA mechanism is incorporated to simultaneously fuse information from different attention heads. The edge relationships between nodes in the graph data are captured by edge convolution (EdgeConv), and the graph structure is dynamically constructed based on the relationships between nodes. Then the features of the point cloud are extracted by the three attention heads with different weights and different foci. Finally, an up-down-up structure is used to extend the features and reconstruct the 3D coordinates of the output point cloud. The superiority of DGCMSA-PU in the up-sampling task is verified through experiments comparing it with existing up-sampling networks, and the robustness of the network to noise and varying number of input point clouds, as well as the important role of the Multi Headed Attention module in the performance improvement of the network, are analysed through robustness and ablation experiments.
