Getting into Good Debt: Race, Debt, and the Pursuit of Freedom

#BankBlack. #BuyBlack. In the wake of deadly police murders of unarmed Black women and men, calls for greater investment in Black business emerged as one panacea for the myriad divisions rending the very flesh of the American promise. In July 2016, hip-hop artist and business owner Michael “Killer Mike” Render issued a call to action days after the police murders of Alton Sterling and Philando Castile. “We owe them our outrage,” he stressed in a call-in to a town hall meeting sponsored by cable television channels MTV and BET and hosted by a popular local Atlanta radio station. “But,” he countered, “we don't have to burn our city down.” Instead of burning, he challenged 1 million people to open a 100-dollar account at a Black bank. Days following Killer Mike's call to “bank Black,” about 8,000 Atlanteans opened accounts in Citizens Trust Bank, a Black-owned bank started in 1921. Riding a catchy hashtag and waves of discontent, the #BankBlack movement quickly spread beyond Atlanta. In less than a year, people around the world moved an estimated $60 million into Black-owned banks.

A look at the GLP‐1 agonists

A couple of years ago, I started exercising at home instead of going to the local Y. I'd typically have a television cable news channel on to keep me company, and was thereby subjected to abundant commercial advertising. Aside from marveling at the remarkably precise targeting of my demographic (old people), I pretty much managed to tune out the content. Recently, however, during more purposeful encounters with the media, I have found myself inundated with discussions of a specific product I had previously only associated with a strikingly annoying jingle: Ozempic.

Risk Analysis on The Construction Project of The 150 KV Bangkalan High Voltage Transmission Network

Electricity project implemented by PT. PLN (Persero) UIP JBTB is a construction project of the High Voltage Transmission Network and High Voltage Cable Channel 150 kV Bangkalan. The construction will certainly stretch across various terrains that have various levels of risk in the construction process. In addition, the construction project of the High Voltage Transmission Network and High Voltage Cable Channel 150 kV is a very complex project so that each stage has different obstacles so that it has the potential to have high risks in its implementation. The risk management will be based on SNI 8615:2018 ISO 31000:2018 regarding Risk Management – Guidelines and SNI IEC/ISO 31010:2016 Risk Management – Risk Assessment Techniques. The risk management process begins with determining the scope, context and risk criteria and then proceeds with the risk assessment process which includes identification, analysis, risk evaluation and risk treatment. This research was conducted to identify the risks that arise in the High Voltage Transmission Network and High Voltage Cable Channel 150 kV Bangkalan transmission development project and formulate the most effective response for each extreme, very high and high risk category of the project. The risk analysis of the Transmission Network project was carried out using a qualitative method to obtain a risk category. At risk that have extreme, very high, and high categories are risks that cannot be tolerated and a quantitative analysis will be carried out using the Expected Monetary Value method as measured data. Furthermore, with the Decision Tree Analysis diagram, several alternative risk treatment branches will be obtained which will then be analyzed using the multiplication of the response success value with the cost impact value in order to obtain the most effective treatment option. The results of the risk treatment will be categorized into risk mitigation, transferring risk, and accepting risk and the result of residual risk will be known through testing the effectiveness of handling risk treatment. The highest risk in this study is the risk of less than optimal contractor performance which causes project completion to be late with risk treatment by means of the good/services provider process being selected through an auction process which is included in the list of selected providers. The recording the risk register is also carried out as a database in risk analysis research on the construction project of the 150 kV Bangkalan high voltage transmission network.

Youth-powered or empowered: How self-determination theory can help us better understand youth media dynamics with adult facilitators during the pandemic

Youth media literature celebrates youth voice but rarely discusses the power dynamics between adult mentors and youth. This case study explores these power dynamics in cultivating trust between teenagers creating community media and their adult mentors on Chicago’s South Side. The authors identified three self-determination themes relating to these power dynamics between the youth and adults in the production process during the COVID-19 pandemic: (1) generating routines to foster a sense of competency; (2) having a sense of belonging by creating caring interactions; (3) allowing participants to voice their opinion to increase their sense of autonomy. Being Black teenagers in the middle of the pandemic along with the social unrest was challenging. Creating their own media for a specific target audience in their community, instead of a cable TV channel, supported the youth’s sense of power to come intrinsically and not from the adult facilitators.

Media Framing on Coverage of Motorway Rape Incident: A Study of Cable Channels in Pakistan

Evaluating Tiny Houses as a Solution to the Housing Affordability and Environmental Crises

Tiny houses have captured the attention of North American media, with HGTV, the major cable television channel, alone showing three tiny-house related shows: Tiny House Hunters, Tiny House Builders, and Tiny House, Big Living (“HGTV Canada”). One of the first results to appear is the official “Tiny Homes in Canada” website, which claims that tiny homes sit at “the intersection of the housing crisis and the climate crisis” (Tiny Homes in Canada). Notably, this website also proclaims that the tiny home community is a “culturally idealistic response to financial desperation” (Tiny Homes in Canada) and sustainability. Much scholarly research supports the notion that the two primary drivers for tiny house living are affordability and sustainability (Evans; Shearer and Burton). In this paper, I evaluate the actual potential for tiny houses to serve as a solution to the housing affordability and environmental crises, especially in Ontario, Canada. I find that though tiny houses have the potential to be a solution for the housing affordability and environmental crises, they are not a current solution because Ontario legislation renders them somewhat inaccessible. I also explore the lifestyle choices and social conditions associated with tiny house living, as a housing option that is both idealistic (presented as a solution to the overwhelming housing affordability and environmental crises) and pragmatic (financially feasible).

Effect of EVA Polymer and PVA Fiber on the Mechanical Properties of Ultra-High Performance Engineered Cementitious Composites

In order to study the mechanical properties of ultra-high performance engineered cementitious composites (UHP-ECC) used for cable channel repair, orthogonal tests were carried out with four influencing factors, water binder ratio, silica fume, fly ash and mortar ratio, to obtain the optimum mix ratio of the cement paste. On this basis, the effects of ethylene-vinyl acetate (EVA) polymer and polyvinyl alcohol (PVA) fiber on the fluidity, flexural strength and compressive strength of UHP-ECC were studied, and the micromechanism was analyzed with SEM. The results show that the fluidity of UHP-ECC material prepared was 170-200 mm, which meets the requirements of working performance. The average compressive strength at 28 days reached 85.3 MPa, and the average flexural strength at 28 days reached 22.3 MPa. EVA polymer has a fast film forming rate in an alkaline environment. The formed polymer film wraps the fiber, enhances the bridging role between the fiber and the matrix and increases the viscosity of the material. Therefore, the early flexural strength is significantly improved. The 1-d flexural strength of UHP-ECC material mixed with 9-mm fiber is increased by 18%, and the 1-d flexural strength of 3-mm fiber is increased by 15%. Due to PVA fiber's high elastic modulus and tensile strength, it improved the flexural and tensile properties of the material after incorporation, especially in the later stages; the 28-d flexural strength of UHP-ECC material mixed with 9-mm fiber increased by 12%, and the 28-d flexural strength of 3-mm fiber increased by 7%. It was concluded that the effect of 9-mm PVA fiber is better than that of 3 mm PVA fiber.

Регрессионная модель затухания ультразвукового сигнала в скважине

The problem of telemetry information transmitting requires a comprehensive study of new communication channels and finding transparency windows for wave propagation in the operating frequency band. Electromagnetic communication channels are energy inefficient and have a low data transfer rate. Cable communication channels have high maintenance costs, and telemetry transmission is impossible at large depths. This paper provides a brief overview of the methods of telemetry information transmitting. The outcomes of the design of a receiving and transmitting ultrasonic device for telemetric information transmitting are presented. The receiver and transmitter are based on the piezo-emitter ZP-25. The frequency of the transmitted signal is 40 kHz. An experimental installation simulating a part of a producing well was used to study the acoustic signal propagation. As a result, a linear regression model of acoustic signal attenuation in the well was received. A comparison is made with the theoretical model of acoustic signal propagation. The discrepancy between the obtained and theoretical model is found. It is shown that linear regression is consistent with experimental results, it is a good simulation model for the signal transmission process, and nonlinear effects in the frequency band under consideration are insignificant. Also, the experimental model has much less attenuation compared to the theoretical one.

SELECTION OF THE TECHNIQUE OF ARRANGEMENT OF EQUIPMENT SERVICE AREA TO PROVIDE THE PERMISSIBLE TOUCH VOLTAGE

Ensuring the permissible value of the touch voltage in operating electrical installations is a necessary condition for the electrical safety of personnel and third parties. In the study, based on literature data, it is analyzed in which cases it is impossible to achieve the permissible values of the touch voltage only with the help of the design of the grounding system. It is shown that ensuring the permissible value of the touch voltage is performed by arranging in a special way both the place of operational maintenance of the equipment and the territory of the opendoor switchgear. It is study the selection a technique of arrangement of the service place to ensure the permissible value of the touch voltage on the equipment of the opendoor switchgear during a single-phase short circuit to the ground. When performing the work, statistical methods of analysis, the ammeter-voltmeter method for experimental determination of the resistance of the base according to the method of Research&Design institute "Molniya" NTU "KhPI" were used. For the first time, on the basis of statistical data, the necessity of arrangement of equipment service area to ensure an acceptable value of touch voltage at operating substations of class 110 (150) kV and 330 (220) kV was analyzed. The spread of base resistance (ground resistance of human foot) values was determined experimentally. The most common ways of arrangement of equipment service area were analyzed: technological (natural), namely: a reinforced concrete pool with a layer of crushed stone, a cable channel or tray, asphalt paths and specially created (artificial) ones, namely: a metal structure , a layer of crushed stone, reinforced concrete slabs, concrete slabs without scaffolding, paving slabs, concrete slabs (paving slabs) with gravel admixtures, polymer sand slabs. The base resistance was measured for the listed techniques at operating substations. The advantages and disadvantages of various arrangement of equipment service area are determined, and recommendations for their use are provided.

ALGORITHMS FOR SEARCHING FOR AN ACCEPTABLE OPERATING MODE OF A CABLE CHANNEL BASED ON AN ASSESSMENT OF ITS TEMPERATURE STATE

The great majority of currently used cable products contain polymer materials in their construction, which tend to degrade their physical and electrical properties over time. This process is aggravated when the temperature of the product increases. The design of cable lines and the conditions of their collective laying, for example, in cable channels, complicate the thermal control of their operation, while the conditions of an isolated channel contribute to the heating of individual lines at the expense of neighboring ones. The existing engineering methods for calculating the cable temperature specified in IEC 60287-1-1-2009 do not allow taking into account all the features of a particular cable structure. Therefore, the task of a quick and accurate assessment of the thermal state of all polymer elements of the lines laid in the channel is very urgent. The paper considers the possibility of replacing direct observation of the thermal field of a cable channel with its equivalent mathematical model capable of determining stable stationary temperature distributions at given current loads of lines. Such a model, in addition to the speed of finding the desired parameters, has such an advantage over a real line as the ability to evaluate the internal temperature field of the cable without violating the integrity of its design. Using a mathematical model, it is proposed to analyze the thermal state of the channel by comparing the temperatures of the elements of cable lines with a predetermined setpoint. When the fact of exceeding the setpoint is detected, an algorithm is started for selecting such a combination of current loads at which the temperatures of the line elements do not exceed the set value. An additional criterion for selecting the mode is the minimum reduction of currents in comparison with their initial value. The algorithms proposed in this paper are universal and can be used for channels of various designs and with different numbers of lines, as well as for analyzing the operation of similar engineering structures, for example, ventilation ducts with transit lines of air conditioning systems, pipelines for hot liquids and gases. The developed algorithms are functionally suitable for creating specialized software operating in the mode of an adviser to the operator of an electricity distribution node. The software is designed to pre-evaluate any change in line loads, checking for possible overheating and giving the operator either approval of the mode, or offering a safe option for long-term operation.

Modernization of the technological communication network at railway transport facilities using PON technology

The existing telecommunication network the construction principle of which is nowadays based on active equipment that is required to be serviced due to its outmoded technology was considered. The modernization measures of telecommunication network at large freight terminals with the use of PON technologies which allow to complete properly and on time freigh handling, receipt of cargo, dispatch of cargo, making up and breaking down of cargo trains, shunting works were provided. It was decribed the stucture of PON technology which includes one OLT optical line terminal per network, a set of nodes of ONT subscribers connected to OLT by means of splittera over one fibre. OLT allocates time for information broadcasting to avoid the overlap of outgoing signals, to improve communication quality, noise immunity from ONT subcribers. Modernization of telecommunication network suppose the replacement of existing electrical cables laid in the cable channels on the fiber optic. Located at the station equipment and ATS Definity SI in the line-switching room will be removed. There will be a new small-size multifunctional equipment which allow to connect a large number of subscribers providing a broad range of service. Properly selected type of optical cable will allow to achieve a long duration of use of a new technological network with further development prospects, to use it only for organizing work at a large freight railway station.

Application of Big Data Clustering Algorithm in Electrical Engineering Automation

The existing control methods have the problem of imperfect automatic distribution linkage model, which leads to excessive noise in the process of practical application. This paper designs an electrical engineering automation control method based on big data clustering algorithm, obtains the load parameters of power cable laying mode, arranges the cable channels hierarchically, extracts the technical characteristics of electrical engineering automation control, integrates the equipment operation information, builds the automatic distribution linkage model, mines the data rules of power index, sets the distribution structure of electrical equipment by big data clustering algorithm, and centrally configures the functional units.Experimental Results. Compared with the other two control methods, the average noise of this control method is 19.774 dB, 35.462 dB, and 36.323 dB, which proves that the control method combined with big data clustering algorithm has better practical application effect.

Research of an intelligent fire extinguishing device for dense cable passage

In recent years, there have been many cable (accessory) burning events in the cable channel of the company, indicating that the fire isolation measures of dense cable channel and cable intermediate joint are still not perfect, and there are still fire risks. In view of the characteristics of dense cable passage, this paper puts forward a design idea of intelligent fire extinguishing device suitable for dense cable passage. It introduces the structure of each module in detail, puts forward the function of the device and fire extinguishing principle, and expects to provide a new technology for the fire prevention and control of cable passage.

Cable passage fire extinguishing equipment is a reliable infrastructure to eliminate cable fire, and detection components are the key to correct and timely action of fire extinguishing equipment. This paper designs a temperature detection module based on DS18B20, and discusses the design principle from the aspects of internal structure, command sequence, signal mode and so on.

Импульсное пожаротушение - состояние вопроса

Проведен анализ имеющихся разработок средств пожаротушения, основанных на импульсном способе подачи огнетушащего вещества (ОТВ). Сделаны предположения о механизме прекращения горения при подаче ОТВ в очаг пожара импульсным способом. Отмечена перспективность применения импульсного способа подачи ОТВ в различные очаги возгорания. Принцип построения импульсного пожаротушения позволяет легко составлять конфигурацию под различные требования, а также дает возможность наращивания существующих систем противопожарной защиты. The problem of eliminating fires spreading over large areas in closed and semi-closed spaces (warehouses, cable channels, high-rise buildings, etc.) is important and difficult to solve. Firstly, it is difficult to get close to such fire, therefore it is necessary either to solve the problem of supplying extinguishing agents from a long distance which complicates the fire extinguishing process or to install automatic fire extinguishing systems in close proximity to the source that is very difficult due to potentially destruction by possible explosions. Secondly, in order to suppress a developed fire from a long distance it is necessary to supply extinguishing agent continuously for a long time or to supply a large amount of extinguishing powder directly to the flame source at the same time. It is a very difficult task since it is necessary to get into a small diameter relative to the distance to it. The aforesaid suggests that it is necessary to investigate various ways of supplying a fire extinguishing agent. The paper provides an overview of the development of fire extinguishing means based on a pulse method of supplying the extinguishing agent to the ignition source. Currently special attention is paid both to the development of such technologies and to the creation of such fire extinguishing tools that would allow suppressing fire without coming into direct contact with it. Direct contact with fire means that a person exposes to a number of fire hazards: high temperatures, lack of air and visibility, risks associated with the unpredictability of the situation. In some cases, successful suppression of the source of combustion can be ensured by means and methods of extinguishing that allow remotely supplying of fire extinguishers directly to the combustion zone in a short period of time (1-2 s) in the amount necessary to suppress the fire. The pulse supply method developed and implemented in various kinds of devices meets this requirement in terms of its potential capabilities.

WAYS TO PUBLISH PUBLICATIONS

Decades ago, people hurried to read newspapers. He was ready to count to the last penny in order to buy an interesting edition. At that time, the format and size of the newspaper were different, external beauty was not paid much attention to, it was strict, standard, gray. There were long columns and sloppy lyrics. However, the public was interested in the abundance of news on the pages of the publication. It is not easy to please the modern reader. Television, radio, computers, various CD-MD-DVD players, satellite and cable TV channels attract audiences and make periodicals uncompetitive. However, editors of newspapers and magazines tend to compete and consider different ways to meet the needs of the reader. Undoubtedly, there is room for an attractive design of the publication. The designer and layout designer of a newspaper can be compared to an architect and a builder, and the main elements of the design of a newspaper can be compared to the bricks from which a building is being built, that is, a newspaper issue. Designers and layout designers solve a complex of problems related to the plan of this construction – with the composition of numbers and bands, with the placement of materials, etc. The composition of the pages depends on the composition of the entire issue of the newspaper, which in turn is determined by the content of the published materials and their nature. In almost every newspaper, a more or less stable composition is gradually taking shape, which means the design of the pages, the main sections and headings characteristic of this publication. The article discusses some methods of layout of newspapers and magazines.

Scientific and technical Development of transtelephone Electrocardiography in foreign Countries during the 60-80s of the twentieth Century

In the context of the scientific and technical history of electrocardiography, the development of transtelephone electrocardiography (tele-ECG) remains unexplored - as a set of technical and methodological aspects of remote ECG transmission via telecommunication. This direction played a significant role in medical science and practice in the middle of the twentieth century, in many ways it remains relevant to this day. The task of the study. To identify and systematize the patterns of development of scientific knowledge related to the creation and use of transtelephone electrocardiography technologies in the period of the 1960s-1980s in Europe, Asia, North America and Australia. Results. From the point of view of technical sciences, there were two main trends in scientific research: a) the design of hardware solutions for broadcasting and receiving ECG via cable or radio channels; b) the development of algorithms for computer analysis of ECG. From the point of view of medical sciences: a) clinical trials, including an assessment of the technical reliability of equipment; b) evaluation of the diagnostic accuracy of remote (both "human" and machine) interpretation of ECG; c) study of the clinical significance of tele-ECG. When comparing the trends of scientific and technological development of transtelephone electrocardiography in foreign countries, it is obvious that the countries of Europe and Asia follow in the wake of medical science in the USA. In the studies of scientists from Eastern Europe, the influence of medical science of the USSR in the form of the use of tele-ECG in occupational medicine is noted. Conclusions. In the period of the 1960s-1980s, the scientific and technical development of transtelephone electrocardiography took place in many countries of the world, but the activity and significance of these processes seriously differed. The emergence of affordable and reliable technologies for remote counseling, as well as automated analysis of electrocardiography results, has become significant. The overall result was the emergence of clinically significant remote diagnostics techniques and new models of medical care organization based on them.

HGTV’sHouse Huntersand the Right to Coziness

This article explores the complex appeal of home-buying and renovation shows on the cable channel HGTV. While their popularity is clear, their political implications are murkier. Some media studies scholars accuse the genre of fostering consumerism, conformity, and neo-liberal nationhood. Others admire its inclusion and “non-special treatment” of queer and racially diverse participants. My own feminist reading notes the limits as well as merits of the diversity defense and offers to appreciate the shows’ contribution in somewhat different terms. Focusing specifically on House Hunters (1999-present), I credit this home-buying series with asserting the primacy of domestic life in conjunction with a host of related values conventionally coded and subordinated as ‘feminine.’ In the hegemonic scheme of things, qualities coded as ‘masculine’ (the aggressive, historic, large-scale, public-sphere, self-reliant, and individualist) occupy a superior position. House Hunters challenges this gendered hierarchy by reveling in the modest, everyday, small-scale, private-sphere, interdependent, and relational. It does so, moreover, in a gender-neutral way: no longer written off and relegated to women, the little things that happen in houses are made paramount for male and female viewers alike. Adding a further twist, I close with an episode whose homebuyers have histories of social marginality and economic insecurity. In this context, the desire for domestic ‘coziness’ is less about conformity to bourgeois norms and more about feelings of safety and belonging in relation to place.

Optimization of Load Balancing with Feeder Network Reconfiguration Using ETAP Simulation

Increasing electricity demand for tourism in Canggu Area of Bali Province, Indonesia has made the Tangeb feeder overloaded with load current more than 150 amperes. This results in voltages drop for 84 buses (59.15 %) below 19 kV. In this research, design and simulation of network reconfiguration to improve the voltage profile and reduce power losses were done using ETAP 12.6 software. The reconfiguration of network was done by changing the Load Balancing Switch (LBS) of Dukuh Sengguan to Normally Open (NO) as well as adding a Medium Voltage Twisted Insulated Cable (MVTIC) channel from Pemaron-Munggu LBS toward Dukuh Sengguan LBS to transfer part of the load from the Tangeb feeder to the Kaba Kaba feeder. The simulation results showed that the voltage profile after reconfiguration has improved above 19 kV with the lowest value being 19.275 kV for the Tangeb feeder and 19.238 kV for the Kaba Kaba feeder, respectively. The total power losses of the two feeders after reconfiguration were decreased from 226.748 kW to 178.731 kW.

Romantic blockbusters: the co-commissioning of Korean network-developed K-dramas as ‘Netflix originals’

ABSTRACT Since Netflix started offering its multinational service in South Korea in 2016, the company’s main strategy has been to enter into partnerships with local legacy networks in the form of co-commissions and offer locally developed K-dramas as ‘Netflix Originals’. In this paper, I analyse the industrial changes that led to the Korean cable channel tvN and Netflix co-commissioning television series, focusing in particular on Mr. Sunshine (Miseuteo syeonsyain, 2018) and Crash Landing on You (Sarangui bulsichak, 2019-2020) as the culmination of the many successful K-dramas developed through this partnership. Renowned internationally for productions in the romance genre, K-drama has evolved rapidly since the enormous success of Winter Sonata (Gyeoul yeonga, 2004), the series that initiated the Korean Wave in Japan. These programs continue the decades-long lineage of romance-themed K-dramas by terrestrial broadcasters while offering enhanced production values made possible by infusions of capital from Netflix, which have fuelled the evolution of K-dramas into what I have termed ‘romantic blockbusters.’ I examine the triadic relationship among the key stakeholders—the local networks, the local production companies, and Netflix—to trace the development of local network-developed K-dramas into internationally circulating Netflix Originals.
