Evaluation of Clinical Subacromial Impingement Test Positive Patients with Ultrasonographic Subacromial Impingement Test
Authors: Tombak Yasemin , Karaahmet Özgür Zeliha
Published: June 2024

Objective: Knowing which of the special clinical tests used in subacromial impingement syndrome is more successful in making the diagnosis is important for patient evaluation, determining if further examination is necessary, and arranging treatment. Utilizing sonographic impingement as a reference diagnostic technique, the study sought to evaluate how well clinical test results performed in diagnosing patients with subacromial impingement syndrome.
Material and method: The study involved 42 patients with shoulder pain and at least one positive subacromial impingement test, including Neer, Hawkins, or Yocum tests. Dynamic sonographic compression of the tendon in the coracoacromial area was examined by abducting the shoulder. Dynamic sonographic compression findings were compared with clinical examination tests.
Results: In 40.5% of the patients, the ultrasonographic impingement test was positive. Hawkins test was positive in 81% of patients, Neer test was positive in 69% of patients, and Yocum test was positive in 78.6% of patients. A significant relationship was found between the ultrasonographically evaluated subacromial impingement test and the Neer test, but no significant relationship was found with other special tests (Hawkins and Yocum test) (p = 0.02, p = 0.4, p = 0.12, respectively).
Conclusion: We have demonstrated a significant relationship between the ultrasonographic finding of dynamic subacromial impingement and the Neer test, which is a non-invasive and device-independent physical examination test.

Authors: Şahin Mehtap , Okçu Nihat
Published: June 2024

Objective: The aim of this study was to determine the relationship between routine laboratory indicators [Including hemoglobin, white blood cells, platelets, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)] and the extent of endoscopic involvement in individuals with inflammatory bowel disease (IBD).
Material and Method: The medical records of patients who were diagnosed with Ulcerative Colitis (UC) and Crohn’s Disease (CD) between 2009 and 2015 were retrospectively examined. Endoscopic findings and hemoglobin, white blood cell, platelet, ESR, and CRP values at the time of colonoscopy were analyzed. An exploratory multinomial regression model was created to examine the association of laboratory parameters and endoscopic involvement localization.
Results: In UC, a significant decrease in hemoglobin levels was present in cases with extensive colitis/pancolitis compared to distal type colitis (p=0.02), while no significant difference was found between left-sided colitis and distal type colitis. Elevated ESR values were notably found in left-sided colitis (p=0.007) and extensive colitis/ pancolitis (p=0.043) compared to distal type colitis. CRP levels were significantly higher in cases with extensive colitis/pancolitis (p=0.015). No relationship was identified between laboratory parameters and the endoscopic location of involvement in CD.
Conclusion: Although hemoglobin value, ESR and CRP levels are helpful in determining the location of involvement in UC, their effects have not been observed in CD. In addition to these basic laboratory values, other parameters should also be taken into consideration in the evaluation of patients.
A study on THz communications between Low Earth Orbit constellations and Earth Stations
Authors: Flores Aguilar Estephania , Karabulut-Kurt Gunes
Published: June 2024

A non-terrestrial system that uses Terahertz (THz) frequencies is a potential solution to achieving equal access to the Internet worldwide. This paper describes a non-terrestrial system that consists of a Low Earth Orbit (LEO) constellation, Earth Stations in Motion (ESIMs) and standard Earth stations. We examine the effects of rain, fog, clouds and atmospheric gases for this non-terrestrial system for frequencies between 100-300 GHz. The research findings suggest that the frequency bands between 102 - 109.5 GHz are rather suitable for communication between Earth stations and satellites, including ESIMs, reaching in a critical scenario uplink data rates of up to 2.6 Gbits/s with 0.5 GHz of bandwidth or up to 12 Gbits/s with 5 GHz of bandwidth in uplink. For the downlink, we can reach up to 6 Mbits/s with a transmitted power of 29 dBW, but if we increase the power transmitted by satellites, it is possible to reach up to 25 Gbits/s with 2.5GHz of bandwidth. Under clear, blue-sky conditions, we can achieve a maximum data rate of 17.3 Gbits/s for downlink and uplink. For inter-satellite links (communications between satellites in the same orbit or between different orbits), the frequency bands between 111.8 - 114.25 GHz, 116 - 123 GHz, 174.5 - 182 GHz, 185 - 190 GHz are viable, offering speeds from 1.5 to 2.51 Gbits/s when using a uniform rectangular array with 625 radiating elements. This research provides new findings from the amalgamation of existing literature, which is crucial for the future allocation of optimal frequencies between 100 - 300 GHz for satellite services.
Adaptive multibeam hopping in GEO satellite networks with non-uniformly distributed ground users
Authors: Shehata Heba , Inaltekin Hazer , Collings Iain B.
Published: June 2024

This paper designs a novel low-complexity user-cluster grouping algorithm for adaptive beam hopping in geostationary satellite networks equipped with multibeam phased-array antennas. Each beam serves a cluster of users, and the challenge is to design a beam-hopping pattern where no beams are simultaneously serving nearby user clusters. We develop a line search procedure to identify near-optimum groupings for heterogeneous traffic demands. We provide a necessary condition to determine the boundaries of the line search space. Our approach employs exclusion regions around critical user clusters in congested areas, iterates a sequential congestion-based grouping algorithm, and applies a group-member-swapping procedure. It provides max-min fairness for ground users. Extensive numerical studies have shown that our user grouping algorithm produces near-optimum beam-hopping schedules with low outage probability. It achieves an improvement of up to 13dB in the worst-case signal-to-interference and noise ratio, and doubles the zero-outage data rate, compared to benchmark approaches.
Care, agency, and social reproduction in the H-2A context: A case study from Ohio
Authors: Kline Anisa
Published: June 2024

This paper uses the qualitative results of a survey of 285 H-2A workers in Ohio to explore questions of care, social reproduction, and agency within agricultural guestwork. Drawing on frameworks developed in labor and feminist geography, it examines how H-2A workers create community and develop skills of social reproduction during their time in the United States. Countering the common narratives of H-2A worker as victims or stoic, long suffering laborers, the research draws attention to the relational and emotional lives of the men who do this work. By highlighting affective and social dimensions of the guestworker experience, it argues for an approach to questions of agricultural labor that emphasizes the agency, range of experiences, and humanity of the people who participate in the H-2A program.

Accidents can happen unexpectedly and can happen anywhere, such as at home, on the street, including at school. One of the most common cases is a fracture. Knowledge of initial aid for fracture cases from teachers, employees, and even students is an essential point in preventing the worsening of the victim's condition before being taken to a health facility. It is necessary to increase knowledge of prevention and first aid in fracture cases at school by students and UKS coaches. The method of community service activities is education and training on first aid in fracture cases in schools, targeting UKS cadres. After the community service activities, the participant's knowledge about the first handling of fracture cases increased. The implication is that when there is a fracture victim, first aid measures can be given at the scene without waiting for the medical team to arrive.
低價格之層間變位角建築結構健康監測方法研究
Authors: 姚昭智 姚昭智 , George. C .Yao 吳姿穎
Published: June 2024

大地震後為了檢查建築物是否有損壞及保護結構免於因餘震再次破壞，通常會以人工巡檢的方式判斷建築物是否安全，但因需勘查棟數太多致常造成誤判與恢復時間大幅增加的情況。近年來，地震監測網絡已推廣到使用於建築物健康監測上，以便能夠在震後第一時間檢測出損傷位置及破壞程度，快速地進行補強及救災的動作。目前常用的結構健康監測(Structure Health Monitoring, SHM)系統多使用傳統加速度計，但加速度計系統價格昂貴且強震資料易受汙染，因此使得建築物SHM的推廣受到限制，本研究提出低價格的傾斜儀做為SHM之量測設備，可改善上述問題。本研究先透過SAP2000軟體分析某三層樓構架，了解構架之變形特性，且推論出傾斜儀能夠裝設在柱中間做為量測點，可直接測得層間變位角。再研究如何快速判斷建築物各樓層之健康狀況，並且計算出傾斜儀之誤差值。也將此結果應用在2023日本E-Defense足尺十層樓鋼結構振動台實驗，將傾斜儀安裝在受損機會較大之樓層2至5樓。結果顯示出，在沒有破壞發生時，結構沒有殘餘轉角產生，且層剪力對轉角圖為直線；而當結構有破壞發生，會有明顯殘餘轉角以及層剪力對轉角歷時圖會有迴圈發生，跟數值分析之結果類似，故可知道本研究建議之健康監測方法確實可行且具有經濟可行性。

 

After a major earthquake, to check for damage in buildings and protect structures from aftershock damage, manual inspections are usually used to determine whether buildings are safe. However, due to the large number of buildings need inspection, misjudgment may occur and recovery time are often delayed. In recent years, building level monitoring networks have been promoted for building health monitoring, which can detect the location and degree of damage immediately after an earthquake, and quickly carry out retrofit work. The common structural health monitoring (SHM) systems use traditional accelerometers for monitoring, but they are expensive and the data of strong earthquake may be polluted. This study proposes a low-cost tiltmeter for SHM, which can improve the extent of above problems. This study first analyzed a three-story building structure using SAP2000 to understand its deformation characteristics, and infer that the tiltmeter can be installed at the mid-height of the column, which can directly measure the Inter-story Drift Angle (IDA) and quickly determine the building health status. We then applied this theory to a 10-story steel structure test program of E-Defense in Japan in 2023, the MEMS tiltmeter was installed on the four floors with a high chance of damage. The results show that if no damage occurs, there is no residual IDA, and the Story Shear-IDA diagram is a straight line. When damage occurs, there is a residual IDA and a hysteresis loop on the Story Shear-IDA diagram.

This paper aims to undertake a Kierkegaardian investigation into Elie Wiesel’s writing of his memorable but nihilistic Holocaust memoir, Night. Documenting the meaningless death of Auschwitz and the despair of its horror, such memoir writing is tremendously elusive and difficult to read, even impossible for "interpretation." To tackle this hermeneutical challenge, this study attempts to employ a counter-nihilistic approach to Wiesel’s writing of Holocaust nihilism and the post-Holocaust "imprint of death" via appropriating Kierkegaard’s existential-religious ideas about despair, religious anxiety, and constituting the self. With the intent to venture deep into the "dead-land" existence situated in the de-humanized universe of no meaning, no hope and no God, this Kierkegaardian examination of Wiesel’s memoir writing attempts to explore whether the writing of the horrible memory can be seen as invested with anxiety of meaning and living, and the voiced anger as the expression of rebellion against (post-)Holocaust despair. Ultimately, through ascertaining the rebellious spirit embedded within Wiesel’s writing vis-à-vis Kierkegaard’s thinking of faith in God, rather than mere defiance against death, as crucial for tackling nihilistic despair, the study concludes with understanding Wiesel’s memoir writing as an enterprise more of "the messenger of the dead" than of "the messenger of God."

The nutritional status of school children is important for their growth, development, and overall well-being. Poor nutritional status of the school children can have a huge impact not only in the short term but also for their long lives. This study aimed to investigate the nutritional status and its associated factors among adolescent school children in Pyin Oo Lwin Township, Mandalay Region. A cross-sectional study was conducted from August to December 2023 among 202 school children in public schools of Pyin Oo Lwin Township by simple random sampling method using face-to-face interviews with pretested structured questionnaires. Anthropometric measures were taken, and nutritional indicators were calculated using the WHO Anthro Plus software. Data analysis was conducted using SPSS version 16. Bivariate and multivariable regression analyses were performed to find the associated factors of nutritional status. Among 202 students, aged between 14 and 18 years, 83.7% had normal nutritional status while the prevalence of thinness, overweight, and obesity were 12.4%, 3%, and 1%. Most of the school adolescents had a high knowledge level (80.7%), and 77.2% had adequate dietary diversity. According to multivariable analysis, dietary diversity was the major influencing factor on malnutrition of the school children. The students with an adequate dietary diversity score were 70% less likely to be malnourished compared to those with an inadequate diversity score [AOR= 0.30, 95%CI = (0.13, 0.67), p-value=0.003]. Therefore, the study would like to recommend promoting nutrition education specifically on diverse food consumption to achieve a balanced diet and prevent malnutrition among the students.

Abstract: Studying synthetic fuels is imperative due to their potential to offer sustainable alternatives to conventional fossil fuels, thereby addressing environmental concerns, enhancing energy security, and facilitating the transition to cleaner and more efficient transportation systems. This study presents an experiment analysis concentrating on spray characteristics of five types of synthetic fuels (bio-naphtha, EtG, G40, bio-ethanol, and DMC) in a comparison with gasoline. The experiment was conducted ranging from non-evaporated conditions to evaporated conditions, to thoroughly assess the spray behavior of the tested fuels. Results showed that EtG and G40 share similar properties with conventional gasoline. The discharge coefficient (Cd) was found to increase closely linearly with the square root of fuel density. Under non-evaporated condition (Ta = 25 °C), except for DMC, the spray tip penetration of other fuels deviates within ±5% compared to gasoline. Under evaporated condition (Ta = 200 °C), EtG maintains a spray tip penetration within ±5% of gasoline, while bio-naphtha, G40, and DMC fall within ±10% of gasoline. Notably, bio-ethanol shows a 12% higher penetration compared to gasoline, likely due to its slower evaporation and higher latent heat of vaporization.
A contribution to the study of mortars prepared with recycled sand

Published: June 2024

No one denies that today concrete is the most used material in the field of civil engineering. It is widely admitted that the production of concrete necessitates large quantities of fine aggregates, specifically river sand and crushed sand. Moreover, the excessive exploitation of river sand, which generally causes a multitude of environmental problems, has pushed the majority of governments around the world to issue rules for the purpose of limiting or preventing the illegal extraction of river sand. The present article aims primarily to make a contribution to studying the possibility of replacing natural sand (NS) and crushed sand (CS) with recycled sand (RS) in ternary mortars, at proportions ranging from 20% to 100%. The consistency of the mixtures, the densities in the fresh and hardened state, the compressive strength after 3, 14 and 28 days of hardening, as well as the absorption of water by immersion and by capillarity at 28 days, were determined and discussed. It should be noted that the (W/C) ratio was set at 0.7 for all mixtures.
The experimental results showed that recycled sand could be successfully used as an alternative to natural sand, up to a rate of 40%, for the manufacture of ternary mortars without significantly affecting their properties.

Authors: Dias Laura Soares dos Santos , Freire Danielle Cardoso Albuquerque Maia
Published: June 2024

Introdução: A Síndrome do Envelhecimento Precoce Bucal (SEPB) trata-se de uma doença que abrange diversas áreas da odontologia e da saúde, sendo assim, classificada como multifatorial. Por isso, é de suma importância que os profissionais dentistas estejam cientes de suas principais características para um diagnóstico preciso e evitar problemas endodônticos. Objetivo: Pontuar as principais causas de alterações pulpares nocivas relacionadas à evolução da Síndrome do Envelhecimento Precoce Bucal quando não diagnosticada e tratada precocemente, bem como seu diagnóstico e meios de tratamento efetivos conhecidos na atualidade. Metodologia: Este trabalho trata-se de uma revisão de literatura com 37 referências entre livros, artigos e sites publicados entre os anos de 1991 e 2023 retirados do Google Acadêmico, Scielo, PubMed e Periódico Capes. Discussão: Por se tratar de uma síndrome que abrange diversas áreas da saúde é importante que os dentistas estejam cientes sobre as lesões não cariosas, hábitos parafuncionais e distúrbios oclusivos, bruxismo, apertamento e distúrbios psiquiátricos relacionados. Dessa forma, é possível estabelecer um diagnóstico confiável e concreto que ajuda no planejamento do tratamento dos pacientes de acordo com suas necessidades e, como trata-se de uma doença multifatorial e multidisciplinar, saber acionar corretamente os profissionais que farão parte da equipe de tratamento da SEPB de forma individualizada para cada caso. Como endodontista, é necessário conhecer a fundo os temas discutidos neste trabalho para ajudar no diagnóstico e possíveis tratamentos. Conclusão: Como a SEPB é considerada uma síndrome de causas mecânicas, químicas, biológicas e psicológicas é necessário um conhecimento aprofundado de diversas áreas da saúde em relação as suas causas, diagnóstico e tratamento para que se possa evitar um comprometimento inflamatório ou necrose pulpar devido a um diagnóstico e tratamento tardios.

A pesquisa teve como objetivo analisar os aspectos emocionais da interação professor-aluno no contexto do processo de aprendizagem, fundamentando-se em referenciais teóricos-metodológicos elaborados a partir das contribuições de diversos autores, especialmente no campo da psicologia. Lev Vygotsky e Henri Wallon emergem como figuras centrais, oferecendo discussões cruciais sobre desenvolvimento e aprendizagem. No âmbito educacional, as reflexões críticas de Paulo Freire, particularmente sua crítica à educação bancária, também são consideradas. As bases teóricas de Wallon (1971) e Vygotsky (1984) enfatizam a importância da interação social nos processos de aprendizado. Para Vygotsky (1991), a aprendizagem é um constructo elaborado pelas recombinações realizadas pelo sujeito ativo nos contextos culturais e de conhecimento. Wallon (1971), por sua vez, destaca que as expressões do sujeito, como gestos e até mesmo a respiração descompassada, podem ser observadas e identificadas no processo de aprendizagem. Freire (1987) ressalta a necessidade de o sujeito questionar o conteúdo ensinado para encontrar significado no aprendizado, promovendo uma educação mais dialogante e participativa. Esta pesquisa investigou também as características da interação professor-aluno e os aspectos emocionais envolvidos no processo de aprendizagem. A motivação do aluno em sala de aula foi particularmente destacada, buscando relacioná-la com os aspectos interacionais. Os resultados deste estudo ofereceram insights valiosos sobre a relação dos alunos com a escola e evidenciaram o impacto dos sentimentos e motivações no processo educacional. Este estudo proporciona uma oportunidade para repensar os modelos educacionais existentes, que muitas vezes são caracterizados por uma abordagem pouco dialógica, silenciadora e carente de participação, abrindo assim novos horizontes para o campo educacional.

Microbial resistance to antibiotics is a global threat and the World Health Organization (WHO) predicts that future pandemics will involve resistant microorganisms. Recently, the WHO published a list of pathogenic microbes whose priority level varies among medium, high and critical. All bacteria in the list can form biofilms. Biofilms are structures made of polymeric adhesive matrix composed by multispecies in close association. Additionally, biofilm provides an important physical barrier. Different phenotypes are found in biofilms, ensuring resistance to oxidative stress, as well as environmental stress factors. It results cell persistence because there is generation of a gradient of chemical inhibitors at subinhibitory levels, which promote the development of resistant subpopulations able to grow and disseminate. Clinical analysis laboratories are sources of selective pressures for potentially pathogenic bacteria because different substances are handled and discarded daily by the effluents generated. This study assessed the activity of a highly toxic leachate on isolates of Pseudomonas aeruginosa recovered from the sinks of a university clinical analysis teaching laboratory. In vitro biofilm formation tests, pyocyanin quantification, cell wall hydrophobicity test, motility test and susceptibility to seven antibiotics were carried out. The isolate with the most antibiotic resistance was assessed. There was a reduction in adhesion of 14 to 430%. Biofilm was formed, however, on all tested materials; the cells preferentially adhered to hydrophilic surfaces, dolomite, followed by galvanized iron and glass. Maximum pyocyanin production was 12 mM. Swimming motility was stimulated, recording a 12-fold increase in speed, while swarming and twitching motility were inhibited by around 20 and 60%, respectively. All isolates were resistant to cephalosporins and one isolate was detected resistant also to ciprofloxacin. The results indicated that P. aeruginosa survived the leachate, triggering different adaptive physiological responses to persist in the stressful environment.

Authors: REHMAN AU , ULLAH S , HAIDER SF , SAJJAD A
Published: June 2024

Extracorporeal Shock Wave Lithotripsy (ESWL) is a keystone in the harmless management of urinary tract stones, offering a viable alternative to surgical mediation for patients pained by urolithiasis. Objectives: The study aims to find the ESWL efficacy for various density stones (HU) on plain CT scans. Methods: This observational study was conducted at CMH Lahore from February 17, 2024, to May 16, 2024. Data were collected from 180 patients suffering from renal stones. Males represented 60% (108 patients), while females 40% (72 patients). Predominantly, stones were located in the renal pelvis (45%), followed by the upper ureter (30%) and lower ureter (25%). The mean stone size was 10 mm, ranging from 5 to 20 mm, with a corresponding mean stone density of 900 Hounsfield Units (HU) as measured on Plain CT Scan. Results: Data were collected from 180 patients. The mean age of the patients was 50.98±2.34 years. There were 60% male and 40% female patients. According to stone location, 45% are located at the renal pelvis, 30 at the upper ureter and 25% at the lower ureter. A mean reduction in the stone size of 65% post-treatment underscores the procedure's ability to facilitate stone disintegration. Stone-free rates varied based on stone density, with higher rates observed for stones with lower densities: 85% for stones ≤ 700 HU, 75% for stones > 700 HU and ≤ 1000 HU, and 65% for stones > 1000 HU. Conclusion: It is concluded that an accurate assessment of stone density and ESWL score is vital in directing treatment decisions and upgrading outcomes for patients going through ESWL for urinary stones. These findings highlight the importance of personalised treatment approaches and the potential of the ESWL score as an essential tool in clinical practice.

Published: June 2024

El planteamiento y funcionamiento de los sistemas agroalimentarios capitalistas suponen un reto para el logro de la seguridad alimentaria y para una comprensión más amplia de los sujetos rurales —especialmente de las mujeres— y sus formas locales de producción y desarrollo. En este contexto es apremiante la consecución de medidas que reconozcan el rol que cumplen las mujeres rurales en el aseguramiento del derecho de la alimentación y en el establecimiento de sistemas agroalimentarios alternativos más garantistas. El objetivo del presente artículo es exponer las contradicciones propias de los sistemas agroalimentarios capitalistas, el impacto que han tenido sobre la vida de las mujeres rurales y la paradoja en el rol que cumplen dentro de tales sistemas, en relación con la seguridad alimentaria. Con este fin, mostramos el caso del Comité de Mujeres de la Asociación Campesina de Inzá Tierradentro (Acit), en Inzá, Cauca, como un proceso alternativo de éxito en la incorporación de las mujeres como sujetos activos de cambio en los sistemas agroalimentarios.

Throughout evolution, insects have developed exceptional adaptive capabilities by forming symbiotic relationships with microbes, which are often crucial for their survival. Among shield bugs, such as the Southern green shield bug Nezara viridula, mutualistic interactions with bacteria are common and contribute significantly to the insect’s ecological success. N. viridula is a piercing and sucking insect that relies on symbionts for nutrient supplementation. It is a highly invasive species with a broad dietary range across many plant families and its global spread results in significant agricultural losses. Recent studies showed that the shield bug microbiota can manipulate plant defences, affecting pest insect damage potential, however, the role of N. viridula microbiota remains unexplored. In this PhD thesis, the knowledge gaps in the insect-microbe symbiosis field were addressed and aimed to understand the role and relationship between N. viridula and its associated microbes. Our research revealed that N. viridula has a simple and stable microbiota which participates in digestion, nutrient provision, detoxification and repression of plant toxins which is detrimental to the development of sustainable pest control strategies. This study laid a solid foundation for future research in the area of insect-microbe interactions and their application for agricultural practices and pest management.

This study focuses on improving the predicting accuracy of the daily ASE's weighted price index of the insurance sector (ICI) using a nonlinear spectral model called maximum overlapping discrete wavelet transform (MODWT) with five mathematical functions, namely, Haar, Daubechies (d4), least square (la8), best localization (bl14), and Coiflet (c6). Using a nonlinear spectral model called maximum overlapping discrete wavelet transform (MODWT) with five mathematical functions—Haar, Daubechies (d4), least square (la8), best localization (bl14), and Coiflet (c6)—this study aims to increase the daily ASE's weighted price index of the insurance sector's (ICI) prediction accuracy. The model utilizes a genetic fuzzy system based on Thrift's methodology (GFS.Thrift). The Amman Stock Exchange (ASE) supplied a dataset with 4,478 observations for the purpose of the study. The dataset represented daily data from January 2, 2006, to March 24, 2024. The adaptive GFS.THRIFT model was trained with 90% of the dataset, while the remaining 10% was used to test its prediction performance. Multiple egressions and multicollinearity tests were used to select input variables such as standardized foreign direct investment (FDI), standardized value traded (VT) and consumer price index (CPI). Insights from this study indicate that all input variables are positively related to the output variable. Secondly, the proposed model (MODWT-Haar-GFS. Thrift) significantly outperforms other existing models including the GFS. Thrift model.

Authors: Wang Yiran
Published: June 2024

Recently, the cases that a state with no direct conflict of interest filed an application to the International Court of Justice (ICJ) have raised intensive discussions among international society. This research focuses on the motivation of these applicant states. Through analyzing 6 cases classified in this sort from various angles, and considering the historical background and political environment of the applicant states, it is found that the motives can be concluded as public interest and applicant states interest. The latter covers the pursuit of diplomatic obligation, global attention, alignment of domestic attitude and implementation of the ideology, and better international environment as well as reputation. These motives have close internal interaction, and are highly influenced by diverse domestic and international situations, which can serve as supports or catalysts of the filing of some applications. This article also discusses the development during these 14 years of all motives, and predicts their application in the near future.
The Identification Scope of Duty of Care of Network Service Providers in the Algorithm Recommendation Era
Authors: Hu Wanqi
Published: June 2024

In the era of algorithm recommendation, the Internet has experienced major realistic changes such as "technology neutrality" and "technology cannot", which leads to inevitable changes in the duty of care of Internet service providers. The identification of the scope of the duty of care has become an important focus of dispute in infringement cases of Internet service providers, and the court has exercised its discretion. At present, the scope of the duty of care in Chinas legislation still has some deficiencies, such as low level of legal effect and vague definition standard, and there are also great disputes in the handling of practical cases. Considering the influence of the platform strength, the completeness of the notice and other factors, the scope of the duty of care should be appropriately increased according to the specific case in the infringement litigation of network service providers, and it should be distinguished from the duty of review. Starting from judicial practice, this paper suggests that the current duty of care be refined: according to the time stage of the case, the duty of care is divided into before, during and after, and the duty of care of the platform is appropriately improved in each link.
Redefining Duty of Care: Challenges and Solutions for Network Service Providers
Authors: Song Wei
Published: June 2024

With the rapid development of Internet and algorithm technology, how to judge the "duty of care" of network service providers has become a new problem in the field of network infringement. The main topic of this paper is to focus on what kind of duty of care network service providers should bear, and how to solve the problem of responsibility division and commitment in practice. It begins with a comprehensive analysis of the current legal frameworks in China, comparing them with global standards, particularly focusing on the United States' "Safe Harbor" principle and the European Union's Digital Single Market Copyright Directive. It further discusses the challenges of enforcing the duty of care, emphasizing the variability in judicial interpretations and the difficulties in applying traditional legal principles to modern digital contexts. It highlights the need for clearer definitions and preemptive legal measures to mitigate infringement risks, as demonstrated by proactive copyright declarations like those implemented during the 2022 Beijing Winter Olympic Games. Additionally, it examines the potential misuse of the duty of care in competitive business environments, suggesting judicial and legislative strategies to prevent abuse and ensure a fair application of the law. The conclusion advocates for a collaborative approach to reforming duty of care standards, involving a range of stakeholders from legislators to copyright holders, to ensure they are robust yet flexible enough to accommodate future technological developments.
Applying Multi-Armed Bandit algorithms for music recommendations at Spotify
Authors: Xia Ye
Published: June 2024

This study explores the application of multi-armed bandit algorithms in enhancing music recommendation systems, with a focus on Spotify. It delves into the Explore-Then-Commit (ETC), Upper Confidence Bound (UCB), and Thompson Sampling (TS) algorithms, evaluating their efficacy within the Spotify context. The primary objective is to determine which algorithm optimally balances exploration and exploitation to maximize user satisfaction and engagement. The research reveals that the ETC algorithm, with its rigid exploration and exploitation phases, incurs a notably higher regret value. This rigidity can lead to missed opportunities in identifying optimal choices and hinder adaptability to evolving user preferences. Conversely, the UCB and TS algorithms exhibit remarkable adaptability and a flexible balance between exploration and exploitation. This flexibility translates into more personalized and satisfactory user experiences in music recommendations. However, the selection of the most appropriate algorithm should be contingent on the size and characteristics of the specific user dataset, as well as the fine-tuning of algorithm parameters to align with user preferences and behaviors.
