Implikasi Pasal 16 Ayat 3 Uu No. 28 Tahun 2014 Tentang Hak Cipta Terhadap Pencipta Lagu
Authors: Djuhrijjani Djuhrijjani
Published: February 2023

Perubahan dunia yang sangat dinamis dengan segala kompleksitasnya menuntut manusia untuk lebih kreatif dan inovatif dalam melakukan kegiatan ekonomi. Dalam era globalisasi saat ini ekonomi kreatif menjadi andalan dalam perkembangan ekonomi. Hasil akal budi manusia menjadi sangat berharga dan memiliki peran yang strategis, oleh karenanya harus mendapat perlindungan hukum. Salah satu kekayaan intelektual itu adalah Hak Cipta. Hak Cipta merupakan kekayaan intelektual di bidang ilmu pengetahuan, seni dan sastra. Hak ini adalah hak ekslusif yang terdiri dari hak ekonomi dan hak moral. Hak moral erat melekat secara abadi pada pemiliknya. Sementara hak ekonomi adalah hak eksklusif Pencipta dan Pemegang hak cipta untuk mengambil manfaat ekonomi atas ciptaannya. Ada banyak macam ciptaan yang diberikan perlindungan salah satunya adalah ciptaan atas lagu dan/atau musik dengan atau tanpa teks. Agar motivasi para pencipta lagu untuk terus berkarya, maka harus diberikan perlindungan. Hilangnya motivasi akan berdampak luas pada runtuhnya kreativitas makro bangsa Indonesia. Oleh karena itulah dalam UU No. 28/2014 ini diatur agar motivasi itu terus berkembang, salah satunya adalah dengan memberikan pengakuan bahwa hasil karya ciptaannya dapat diajikan agunan untuk mendapatkan kredit. Sesuatu yang sebelumnya tidak diatur dalam UU No. 19 tahun 2002. Ketentuan ini dicantumkan dalam pasal 16 ayat (3) UU No. 28/2014 bahwa hak cipta dapat dijadikan sebagai objek fidusia. Adanya ketentuan ini dapat dianggap sebagai bentuk penghargaan kepada pemilik hak cipta dan atau pemegang hak cipta. Sebagai salah satu pihak yang dilindungi dengan UU hak cipta, maka pemegang hak cipta atas lagu dapat memanfaatkan pasal 16 ayat (3) tersebut untuk memperoleh kredit dari perbankan. Sebagai sesuatu hal yang baru tentu masih ada hal hal yang masih dalam tahap penyesuaian, termasuk bagi kalangan para pencipta lagu. Namun ternyata indahnya bunyi pasal tersebut tidak seindah syair lagu. Belum adanya aturan lebih terinci serta tidak adanya kepastian nilai jaminan menjadi kendala dalam pelaksanaannya, sehingga pencipta lagu belum dapat merasakan langsung manfaat adanya pasal 16 ayat 3 UU Hak Cipta. Namun walau demikian, upaya Pemerintah dalam meningkakan perlindungan serta manfaat atas hak cipta yang dimiliki pencipta dan hak terkait, perlu kita apresiasi. Untuk selanjutnya dibuat peraturan lanjutan agar pasal tersebut bukan sekedar harapan.

PT. JCC Established in April 1973, PT Jembo Cable Company Tbk. started by producing Low Voltage Electrical Cables - copper conductors. Then continue to add product varieties, such as Low Voltage Cable - aluminum conductor, Medium Voltage Cable, Telephone Cable and Fiber Optic Cable and also expand its market. Production Plant performance can be improved or maintained by conducting regular evaluations of the process. The evaluation carried out is by analyzing OEE (Overall Equipment Effectiveness). OEE (Overall Equipment Effectiveness) is a calculation method used to determine the effectiveness of a process that is being implemented by identifying the percentage of production time that is truly productive which is influenced by three factors, namely availability, performance, and quality. reached 85% or above. The research was conducted by observing the cable production process at the Aluminum Cable Plant and the Copper Cable Plant. Based on the observations made from January 2021 to June 2021, the highest OEE value was obtained for the Aluminum Cable Plant in January and February, namely 97% and 94% while for the next month below 90%. For the Copper Cable Plant, since observing from January 2021 to June 2021, it has not yet reached the required OEE value, which is 85% and above. From the results of the analysis, the main factor is not achieving the OEE Value influenced by the low availability ratio It's because almost 50% of the machines in the Aluminum Cable Plant and 25% of the machines in the Copper Cable Plant don't get a workload.

Exploring the Trading Zones of Digital STS
Authors: Elgaard Jensen Torben
Published: February 2023

Over the last couple of decades, one of the significant developments in digital STS has been the rapid growth in digital methods and tools for data harvesting, analysis and visualisation. The increasing availability and deployment of digital tools raises questions about how to develop an analytic practice that reconciles the theoretical sensibilities of STS with tools and data that may sometimes be grounded in assumptions alien to STS. This article explores these challenges by reporting on two related digital STS projects that were carried out at the Techno- Anthropology Lab in Copenhagen. Drawing on science historian Peter Galison’s notion of trading zones, the article analyses how project participants from different communities of practice exchanged and combined tools, theories and projects in a variety of ways. The article identifies two particular trading strategies: the introduction of assisting ontologies or mini-theories, and the introduction of project-specific problems and success criteria. In the final discussion, the article argues that a reliance on these trading strategies in the future will require digital STS to maintain and cultivate its theoretical sensibilities through a continued dialogue with the broader field of STS, including, in particular, new interventionist forms of STS scholarship.
Why (and how to) experiment with digital social data?
Authors: Blok Anders
Published: February 2023

critically discusses the widespread (re-)turn to the practice and rhetoric of experimentation in the realm of digital social data, big or otherwise, drawing, in part, on personal, col­laborative research experiences. In doing so, the commentary positions science and technology studies (STS) as both a valuable resource for such reflection and a partisan participant in wider on-going epistemic struggles and re-alignments in the digital realm. In particular, I deploy long-standing STS resources to discuss certain well-known ambiguities around ‘the experiment’ as a genre or device of knowledge-making, and explore how such ambiguities play out in contemporary discussions over, and aspirations for, social research based on digital data. Here, while deeply sympathetic to Marres’ and allied STS-based projects for digital research, the commentary also questions some of the slippages and demarcations enacted by its circumscribed re-casting of experimental practice. These slippages, I will show, entail their own unwarranted universalization of what it means to do intervention and, by implication, experimental intervention as part of the practice of STS-informed digital research. As an alternative, I suggest that STS may want to reflect further on, and eventually differentiate more carefully between, various deployments of the practice and rhetoric of digital experimentation, including its own, to more precisely render their divergent conditions and possibilities of epistemic felicity. In doing so, however, I will also suggest that, for all its plural manifestations, STS would do well to revisit earlier pragmatist arguments by, in particular, John Dewey, in order to fully appreciate what the commentary calls the meta-experimental promise of digital social research.
Las entidades de economía social en los programas comunes de activación para el empleo
Authors: De Nieves Nieto Nuria
Published: February 2023

Las entidades de la economía social desempeñan un importante papel en la corrección de los desequilibrios del mercado laboral; reducen el desempleo y la inestabilidad en el trabajo y fomentan la inclusión en el trabajo de colectivos con problemas de acceso o permanencia en el mercado laboral, pero además ofrecen un buen modelo en su gestión. Una manifestación importante de esa función se aprecia en el RD 818/2021, de 28 de septiembre de 2021, por el que se regulan los programas comunes de activación para el empleo del Sistema Nacional de Empleo, que ha implantado un nuevo marco normativo que unifica y actualiza la regulación existente para conseguir una mayor eficiencia y adecuación a las nuevas necesidades del mercado de trabajo. El escenario que configura la mencionada norma contempla la consolidación de la economía social como instrumento fundamental de desarrollo empresarial y social.

Published: February 2023

In the Doctoral Thesis, the vibration correlation technique was developed as a non-destructive test method for evaluating the critical load of shells. Nondestructive methods for calculating the buckling load of imperfection sensitive thin-walled structures are one of the most important techniques for the validation of new structures and numerical models of large-scale aerospace structures. The vibration correlation technique (VCT) allows determining the buckling load for several types of structures without reaching the instability point.

The myeloid C-type lectin receptor (CLR) MINCLE senses the mycobacterial cell wall component trehalose-6,6’-dimycolate (TDM). Recently, we found that IL-4 downregulates MINCLE expression in macrophages. IL-4 is a hallmark cytokine in helminth infections, which appear to increase the risk for mycobacterial infection and active tuberculosis. Here, we investigated functional consequences of IL-4 and helminth infection on MINCLE-driven macrophage activation and Th1/Th17 adjuvanticity. IL-4 inhibited MINCLE and cytokine induction after macrophage infection with Mycobacterium bovis bacille Calmette-Guerin (BCG). Infection of mice with BCG upregulated MINCLE on myeloid cells, which was inhibited by IL-4 plasmid injection and by infection with the nematode Nippostrongylus brasiliensis in monocytes. To determine the impact of helminth infection on MINCLE-dependent immune responses, we vaccinated mice with a recombinant protein together with the MINCLE ligand trehalose-6,6-dibehenate (TDB) as adjuvant. Concurrent infection with N. brasiliensis or with Schistosoma mansoni promoted T cell-derived IL-4 production and suppressed Th1/Th17 differentiation in the spleen. In contrast, helminth infection did not reduce Th1/Th17 induction by TDB in draining peripheral lymph nodes, where IL-4 levels were unaltered. Upon use of the TLR4-dependent adjuvant G3D6A, N. brasiliensis infection impaired selectively the induction of splenic antigen-specific Th1 but not of Th17 cells. Inhibition of MINCLE-dependent Th1/Th17 responses in mice infected with N. brasiliensis was dependent on IL-4/IL-13. Thus, helminth infection attenuated the Th17 response to MINCLE-dependent immunization in an organ- and adjuvant-specific manner via the Th2 cytokines IL-4/IL-13. Taken together, our results demonstrate downregulation of MINCLE expression on monocytes and macrophages by IL-4 as a possible mechanism of thwarted Th17 vaccination responses by underlying helminth infection.
A unified neural account of contextual and individual differences in altruism
Authors: Hu Jie , Konovalov Arkady , Ruff Christian C
Published: February 2023

Altruism is critical for cooperation and productivity in human societies but is known to vary strongly across contexts and individuals. The origin of these differences is largely unknown, but may in principle reflect variations in different neurocognitive processes that temporally unfold during altruistic decision making (ranging from initial perceptual processing via value computations to final integrative choice mechanisms). Here, we elucidate the neural origins of individual and contextual differences in altruism by examining altruistic choices in different inequality contexts with computational modeling and electroencephalography (EEG). Our results show that across all contexts and individuals, wealth distribution choices recruit a similar late decision process evident in model-predicted evidence accumulation signals over parietal regions. Contextual and individual differences in behavior related instead to initial processing of stimulus-locked inequality-related value information in centroparietal and centrofrontal sensors, as well as to gamma-band synchronization of these value-related signals with parietal response-locked evidence-accumulation signals. Our findings suggest separable biological bases for individual and contextual differences in altruism that relate to differences in the initial processing of choice-relevant information.
A systematic hybrid machine learning approach for stress prediction
Authors: Ding Cheng , Zhang Yuhao , Ding Ting
Published: February 2023

Stress is becoming an increasingly prevalent health issue, seriously affecting people and putting their health and lives at risk. Frustration, nervousness, and anxiety are the symptoms of stress and these symptoms are becoming common (40%) in younger people. It creates a negative impact on human lives and damages the performance of each individual. Early prediction of stress and the level of stress can help to reduce its impact and different serious health issues related to this mental state. For this, automated systems are required so they can accurately predict stress levels. This study proposed an approach that can detect stress accurately and efficiently using machine learning techniques. We proposed a hybrid model (HB) which is a combination of gradient boosting machine (GBM) and random forest (RF). These models are combined using soft voting criteria in which each model’s prediction probability will be used for the final prediction. The proposed model is significant with 100% accuracy in comparison with the state-of-the-art approaches. To show the significance of the proposed approach we have also done 10-fold cross-validation using the proposed model and the proposed HB model outperforms with 1.00 mean accuracy and +/−0.00 standard deviation. In the end, a statistical T-test we have done to show the significance of the proposed approach in comparison with other approaches.
A smart secured framework for detecting and averting online recruitment fraud using ensemble machine learning techniques
Authors: Ullah Zahid , Jamjoom Mona
Published: February 2023

With the rise of the Internet and social media, information has become available at our fingertips. However, on the dark side, these advancements have opened doors for fraudsters. Online recruitment fraud (ORF) is one of the problems created by these modern technologies, as hundreds of thousands of applicants are victimized every year globally. Fraudsters advertise bogus jobs on online platforms and target job hunters with fake offerings such as huge salaries and desirable geographical locations. The objective of these fraudsters is to collect personal information to be misused in the future, leading to the loss of applicants’ privacy. To prevent such situations, there is a need for an automatic detecting system that can distinguish between real and fake job advertisements and preserve the applicants’ privacy. This study attempts to build a smart secured framework for detecting and preventing ORF using ensemble machine learning (ML) techniques. In this regard, four ensemble methods—AdaBoost (AB), Xtreme Gradient Boost (XGB), Voting, and Random Forest (RF)—are used to build a detection framework. The dataset used was pre-processed using several methods for cleaning and denoising in order to achieve better outcomes. The performance evaluation measures of the applied methods were accuracy, precision, sensitivity, F-measure, and ROC curves. According to these measures, AB performed best, followed by XGB, voting, and RF. In the proposed framework, AB achieved a high accuracy of 98.374%, showing its reliability for detecting and preventing ORF. The results of AB were compared to existing methods in the literature validating the reliability of the model to be significantly used for detecting ORF.
Multi-objective evolutionary optimization for dimensionality reduction of texts represented by synsets

Published: February 2023

Despite new developments in machine learning classification techniques, improving the accuracy of spam filtering is a difficult task due to linguistic phenomena that limit its effectiveness. In particular, we highlight polysemy, synonymy, the usage of hypernyms/hyponyms, and the presence of irrelevant/confusing words. These problems should be solved at the pre-processing stage to avoid using inconsistent information in the building of classification models. Previous studies have suggested that the use of synset-based representation strategies could be successfully used to solve synonymy and polysemy problems. Complementarily, it is possible to take advantage of hyponymy/hypernymy-based to implement dimensionality reduction strategies. These strategies could unify textual terms to model the intentions of the document without losing any information (e.g., bringing together the synsets “viagra”, “ciallis”, “levitra” and other representing similar drugs by using “virility drug” which is a hyponym for all of them). These feature reduction schemes are known as lossless strategies as the information is not removed but only generalised. However, in some types of text classification problems (such as spam filtering) it may not be worthwhile to keep all the information and let dimensionality reduction algorithms discard information that may be irrelevant or confusing. In this work, we are introducing the feature reduction as a multi-objective optimisation problem to be solved using a Multi-Objective Evolutionary Algorithm (MOEA). Our algorithm allows, with minor modifications, to implement lossless (using only semantic-based synset grouping), low-loss (discarding irrelevant information and using semantic-based synset grouping) or lossy (discarding only irrelevant information) strategies. The contribution of this study is two-fold: (i) to introduce different dimensionality reduction methods (lossless, low-loss and lossy) as an optimization problem that can be solved using MOEA and (ii) to provide an experimental comparison of lossless and low-loss schemes for text representation. The results obtained support the usefulness of the low-loss method to improve the efficiency of classifiers.

Published: February 2023

Thoroughly documenting prey items and diet composition is crucial for understanding a predator’s role in the ecosystem. In gape restricted predators, such as snakes, documenting and analyzing the type and size of the prey is important to interpret their ecological role. We describe the diet patterns of a species of venomous snake, the Terciopelo pit viper (Bothrops asper), from its Ecuadorian populations. Examining the gastrointestinal contents of museum specimens collected over an extensive area of the Pacific lowlands of Ecuador, we encountered 69 identifiable prey items from four major taxonomic groups (amphibians, centipedes, mammals, and reptiles). We evaluated the observed composition of prey to check for differences between sexes and size-classes. To complement our observations of the Terciopelo species complex throughout their distribution, we carried out a systematic literature review. Our data show an ontogenetic shift in diet, with a transition from more diverse diet in juveniles towards a mammal-specialized diet in adults, and distinct proportion of prey taxa between the sexes in the juvenile size class.

Published: February 2023

Different parts of Irvingia gabonensis are used ethno-medicinally in some West Africa culture in the treatment of pain. The stem bark has been reported in the literature to possess analgesic property. In order to evaluate the analgesic potential of the seed extract and the phytochemicals that may be responsible for this effect. This study was aimed at determining the phytochemical contents and the analgesic effect of I. gabonensis. The seed was screened for phytochemicals using standard procedures and GC-MS analysis. It central and peripheral analgesic potentials were evaluated at doses of 50 mg/kg, 100 mg/kg and 200 mg/kg using acetic acid induced abdominal writhing and hot plate methods in Swiss albino mice. Acetylsalicylic acid (100 mg/kg), morphine hydrochloride (2 mg/kg) and pentazocine (15 mg/kg) were used as the standard drugs. ANOVA was used to analyze data from the results and level of significance was set at P ≤ 0.05. Phytochemical screening showed the presence of alkaloid, flavonoid, cardiac glycoside, triterpenoid and saponin. GC-MS analysis revealed thirty compounds mostly fatty acids. At 200 mg/kg of the methanolic extract, there was a dose dependent decrease in writhing response which also compared well with acetylsalicylic acid. From the results, Irvingia gabonensis seed contains compounds that could be responsible for the precieved analgesic activity.

Authors: Pagaldiviti Sandilyan Ramanujam , Roy Birendra Kishore
Published: February 2023

The coronavirus outbreak has severely affected the entire human race, including the Hospitality and Tourism industries all over the globe since January 2020. The outbreak of COVID-19 has affected industries significantly and all educational institutes in India and overseas. Although the option of online or virtual classes has come into practice, hospitality and tourism education remained scant during COVID and India’s lockdown period. Multiple educators from various institutions have lost their jobs, were suspended until further notice, or were terminated during the pandemic. It was almost a common practice for most institutions to retain their teaching staff with half of their remuneration during the last one and half years. It was very challenging for each educator to survive during this uncertain time. The main focus of this research paper is to identify the effect of COVID-19 on hospitality educators from different states of India and to suggest better strategies to overcome this for the sake of higher education in India. This paper looks into how Hospitality Educational institutions have approached the pandemic to explore the various practices/strategies and recommend the best ones for the future.

Published: February 2023

Background: Diabetes mellitus (DM) involves a series of metabolic conditions associated with hyperglycaemia which is caused by defects in insulin secretion and./or insulin action. The aim of this work was assessment of the relationship between Aortic Root (AOR) diameter and type 2 diabetes mellitus (T2DM) in Hypertension (HTN) cases.

Methods: This prospective case control study was carried out on 80 HTN cases. Cases were divided in to three groups: Group A (30 HTN cases) with type 2 DM with good metabolic control (Hb AIC ≤ 7.0), group B: (30 HTN cases) with type 2 DM with poor metabolic control (Hb AIC > 7.0) and C (Control group) 20 HTN, non-DM subjects of the same age and sex group with no other comorbid conditions.

Results: FS had a significant decline in group A (P2 = 0.001) and in group B (P3 <0.001) than C. EF had a significant difference among all groups (P <0.001). Early wave declaration time (DT) had a significant decline in group A (P2 = 0.049) and in group B (P3= 0.023) than C. Tissue doppler early velocity wave had a significant difference among all groups (P = 0.004). Tissue doppler early velocity wave had a significant decline in group A and B than C. (P2 = 0.038. P3 = 0.003).

Conclusions: AOR in HTN cases had a significant decline in DM cases compared with non-DM cases. In our results, glycaemic control didn’t play a significant role in aortic root.

The levels of pH, organic matter (OM), cation exchange capacity (CEC), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in the understudy soil were examined. The measured pH, OM, CEC, Cu, Fe, Mn and Zn levels revealed: 6.04±0.49, 17.68±4.78 %, 7.97±0.81 Cmolkg-1, 5.27±0.82 mgkg-1, 232.49±16.01 mgkg-1, 109.30±9.85 mgkg-1, and 8.40±1.15 mgkg-1, for pH, OM, CEC, Cu, Fe, Mn, and Zn, respectively. The values were within the acceptable limits set by national and international standards.

The study revealed variable relationships between the soil properties and micronutrients in the studied soils at p < 0.05. Soil pH exhibited a strong negative association with all the micronutrients except Zn. However, a strong positive correlation (p< 0.10) was recorded between pH and Zn. OM showed a significant positive correlation (p< 0.10) with Fe, a weak positive correlation with Zn, and a non-significant negative correlation (p< 0.10) with Cu and Mn at p < 0.10. CEC exhibited a fair positive association with Fe and Zn, and a non-significant negative correlation (p< 0.10) with Cu and Mn. The principal component analysis (PCA) identified a combination of anthropogenic and natural impact and the impact of agrochemicals applied as the major factors influencing the properties determined in the studied soils. The study concluded that soil properties have a strong influence on the availability or otherwise of micronutrients in the soil.

This study investigates the impact of groundwater pollution in Oyigbo Local Government Area, Nigeria, and the consequences of solid wastes, quality, and its control. The study was inspired by the uncontrolled way that both home and industrial wastes are dumped on the ground, in rivers, burried, burned, and dumped in trash heaps. Papers and polyethene, tin and metals, ashes and dust, texture and rags, aluminum and other minerals are among the primary solid wastes produced in Oyigbo. These wastes form leachates and gases when they degrade and are washed by percolating and infiltrating rain water into the groundwater, according to an examination of the physical, chemical, and biological properties of raw water at ten distinct places in Oyigbo close to disposal grounds. However, while a small number of the water characteristics evaluated did not meet W.H.O. criteria, the majority did. Despite this, recommendations are given to address the issues, including promoting raw water analysis, awareness campaigns, increased groundwater investigation in Oyigbo, and adherence to the resource management principle. From the results obtained, it was discovered that the mean concentration values of TDS, pH, BOD and COD are 89.24mg/l, 7.62mg/l, 13.87mg/l and 14.58 for leachate samples. Also the mean concentration values for Mn, Cl, Mg in groundwater samples are 62.34mg/l, 22.74mg/l and 2.60mg/l and for well water samples and 57.35mg/l, 28.30mg/l and 1.25mg/l respectively. The characteristics of the domestic well water samples showed a mean concentration of biochemical Oxygen Demand (BOD = 16.26 mg/l), Chemical Oxygen Demand (COD = 18.67 mg/l), Dissolved Oxygen (DO = 4.84 mg/l) and temperature (29.66ᵒC). Also, the characteristics of the groundwater samples showed a mean concentration of biochemical Oxygen Demand (BOD = 13.67 mg/l), Chemical Oxygen Demand (COD = 16.11 mg/l), Dissolved Oxygen (DO = 4.03 mg/l) and temperature (27.16ᵒC). This result shows that there are high level of BOD,COD and DO in Domestic well water than that of groundwater in that location(site).

Drug abuse is a public health issue, particularly among adolescents and young adults. Therefore, the purpose of our study is to determine the prevalence rate of drugs use and to identify certain factors that can serve as predictors of drug use. A total of 431 students from Mohammed V University in Rabat participated in this descriptive cross-sectional survey. The prevalence of drug use (regular users and experimenters) was 32.9%. Cannabis has a frequency of 13%, whereas other substances and other psychotropics have a prevalence of 3.8%. The most common average age of onset of substance use was 15. Males had the greatest likelihood of becoming drug addicts. We discovered a high consumption of drugs among university students at the end of this work, implying the need to establish a programme to combat drug addiction, the starting point of which will undoubtedly be prevention at the primary and secondary school levels, requiring the participation of all those involved in the field of education.
Metrics with irreducible mass leading to a correct parameter dependence of gravitational effects around charged and rotating bodies

The standard metrics outside of charged and rotating sources (Kerr-Newman in general, Reissner-Nordström and Kerr in particular) contain the total mass at infinity, which includes both the mass of a neutral non-rotating body and the mass equivalents of rotational and electric field energies. Therefore, the total mass is related to other parameters of the metric - angular momentum and charge. However, at studying the dependence of gravitational effects on parameters, this relationship was ignored, assuming total mass to be constant at varying angular momentum and charge. This error led to physically absurd predictions about the weakening of gravity and its effects with increasing the rotational and electric field energies. To eliminate such errors, the total mass must be expressed in terms of independent parameters - the mass of the neutral non-rotating matter of the source, charge and angular momentum. Recently this has been done using as an independent parameter the mass determined from the gravitational radius at the pole when the charge is only on the surface (Zakir, 2022). In the present paper it is used “irreducible mass”, earlier defined heuristically as the remainder of total mass after the removal of angular momentum and charge. Earlier, mass formulas expressing total mass in terms of irreducible mass were proposed by Florides (1960) (improved by the author (2022)) for charged bodies and then by Christodolou (1970) for rotating and Christodolou-Ruffini (1971) for charged rotating sources. In the paper, the standard metrics are transformed to metrics with independent parameters by substituting the expression for the total mass according to these mass formulas. It is shown that the metrics in this form lead to a physically correct dependence of the effects of gravity on the parameters, in particular, the growth of the rotation and electric field energies strengthens gravity and its effects, such as time dilation and redshifts, increases radii of orbits and the area of shadow.

Importance

There is a strong and increasing focus on redressing structural racism in health care systems. Structural racism persists by separating clinical care sites that treat patients of racial and ethnic minority groups who are disproportionately covered by Medicaid from sites that treat patients who are White and disproportionately covered by commercial insurance. Practice unification refers to efforts to eliminate this form of segregation.

Objective

To define and investigate the facilitators, barriers, and the effects associated with unification of outpatient practices to reduce structural racism in a large urban health system.

Design, Setting, and Participants

This qualitative study used semistructured interviews conducted within a large urban health system in New York from February to October 2023. Trained researchers interviewed clinical and administrative leaders of outpatient clinical practices that were pursuing unification, and health system leaders overseeing multiple practices.

Main Outcomes and Measures

Thematic analysis was used to identify facilitators of and barriers to unification, challenges and benefits after unification, and persistent dimensions of segregation within clinics that had nominally unified. These insights were used to create a framework for the unification process.

Results

The thematic analysis included qualitative information from 5 administrative leaders, 12 clinical leaders, and 6 health system leaders, and found that unification facilitators were financial benefit, relocation to new facility spaces, and advocacy by leaders and trainees, while barriers were financial concerns, space constraints, and physician and staff attitudes. After attaining and experiencing some degree of practice unification, interviewees reported financial gain, more support staff, perceptions of greater equity, better educational experiences, and increased practitioner and trainee satisfaction. Challenges reported after unification were changes in staff roles, financial concerns, patient dissatisfaction, and difficulties interfacing with segregated practices within the health system. Partially unified practices maintained dimensions of segregation, by practitioner, payer, and/or scheduling/time (temporal segregation).

Conclusions and Relevance

This qualitative study found that outpatient practice unification was perceived to be a financially and equity-driven process with multiple dimensions. However, not all of the unification procedures had been completely implemented. These findings indicate that successful unification of outpatient practices in a large urban health care system requires attention to multiple dimensions, as well as overcoming challenges regarding finances, facility space, reimbursement policies, and patient and staff satisfaction.
