The meaning of social media for women domestic workers during the Covid-19 pandemic

Social media plays an important role during the Covid-19 pandemic, where physical activity and community mobility are limited. Especially for women who work as domestic workers who live with their employers. Social media is the only means for them to connect with the outside world.Previous studies have shown that a person's identity can be shown through the front stage and the back stage. Theoretically, this study analyzing how women domestic workers identify themselves through the online realm using social media. This study uses a constructivist paradigm and a qualitative approach. The research participants were three women domestic worker who were obtained purposively using the snowball sampling technique. Data was collected through in-depth interviews and observation to participants. The results of the study show that social media allows participants to construct a reality in the online realm that is different from their situation in real life. Therefore, social media has a very important meaning for participants, because with social media, participants feel their position is equal to other users. They also have access to create a front stage and a back stage, where they can create their ideal self-identity. The aspect of self that are presented by the participants on the front stage is individuals who are successful and happy with their lives. For participants, this is an aspect of their ideal self, even though it does not represent their actual state.

The Identity Construction of Young Gay on Instagram

<em><span>In Indonesia in the last five years, homosexuals still experience discrimination. This condition causes the gay to create new identities that are constructed. Instagram is a medium that is currently widely used by gay in social interactions. This media is used by gays to construct their identity. This study aims to find out how they construct their identity through instragram social media, and what their identity is different in the real world and cyberspace in Bandung. This research method is qualitative with a phenomenological study approach. The informants in this study were gay groups in Bandung City, expecially gay young. Sampling technique used to purposive sampling with deep interview, observation and documentation. The results of this study say that one's experience of being gay is driven by internal environmental factors, namely the treatment of discrimination from family members, colleague and friends. The popular features of Instagram used by informants on Instagram are posting photo, video, and comment by share story to post. Gays construct their identity through online and offline media. Researchers found that there were two stages (front stage and back stage) played by gays when interacting with others.</span></em>

Leadership as Communicative Practice: The Discursive Construction of Leadership and Team Identity in a New Zealand Rugby Team

<p>In sports teams, the way in which leaders such as coaches and captains communicate with players is vital to the success of the team. However, despite extensive psychological and sociological research on sport, it has rarely been a site of linguistic research. Like many sports, rugby has many traditions and ideologies that influence the way in which teams form identities. This thesis explores the way in which leadership is enacted and group identity forged through communicative practice in a New Zealand rugby team. Using authentic interactions collected using an ethnographic methodology, an analysis is presented of how discourse strategies are negotiated within the team, establishing practices that signify membership of communities of practice (CofPs) and creating identities for individuals as leaders. Leadership discourse is itself viewed as a sociolinguistic practice and defines one of the CofPs within the team. Using the concepts of front and back-stage (Goffman 1959; Richards 2006) to describe different conceptual spaces in which interactions occur, I suggest that discourse in the rugby team is a spatialised practice; the performance of a particular style of leadership constructs the space in which it takes place as public or private, with each contributing to an effective leadership performance. The construction of leadership identity is analysed in terms of stance and indexicality, linking locally constructed identities and discourse strategies to macro identity categories and socio-cultural ideologies. One of the ways in which this is examined is through the role of ritual and formulaic language in the team, showing that while communicative practice is negotiated in the back stage, in the front stage its performance serves to construct team identity while aiming to motivate the players. Furthermore, the structural nature of the game of rugby (i.e. players’ positional requirements) is examined in relation to the different communicative strategies adopted by positionally segregated groups. It is suggested that these groups, although institutionally defined, create meaning for themselves as CofPs by negotiating a shared way of communicating in enacting their role in the team. In sum, this research uses CofP theory to examine how leaders emerge through their linguistic practices. Furthermore, it locates leadership as a spatialised practice and examines how leaders influence the discursive construction of group identity. Finally, the analysis also makes a valuable contribution to the field of sociolinguistic research on sport, a small yet growing area.</p>

Research on the High Reliable Electromagnetic Stirring Power Supply

A reconstructed topology with fault diagnosis and fault-tolerant control strategy of the two-phase quadrature power supply of an electromagnetic stirring system are proposed to improve the reliability of the system. First, if the back stage inverter is faulty, the topology will be reconstructed after the diagnosed fault. The reconstructed topology with the fault diagnosis can be applied twice. Additionally, a fault pulse reset method is proposed to form a fault-tolerant control strategy, for which the high-reliability electromagnetic stirring power supply does not need to switch the control algorithm before and after the failure. The reliability of the electromagnetic stirring power supply is improved greatly. Finally, simulations and experiments verify the correctness of the electromagnetic stirring power supply fault diagnosis algorithm, reconstruction topology, and its fault-tolerant control strategy proposed in this paper.

Design and Assertion Based Verification of RISC-V Processor Subsystems

RISC-V is an open, free standard architecture. As its open-source architecture, it can be used in multiple applications like embedded processors, IoT, artificial intelligence, machine learning, military and defense applications. The parameters like throughput, performance, high speed etc., become essential in designing processor architecture. Pipelining is one such unique feature supported by RISC-V ISA, which basically involves the execution of multiple instructions in single cycle. This feature helps in improving the performance of the processor architecture. RISC-V ISA supports five stages of pipelining they are instruction fetch, instruction decode, execute, memory and write-back stage. The work covered in this paper involves the design and implementation of the subsystems of the RISC-V ISA which are present in different stages of pipeline architecture. The subsystems included in this work are Floating Point Unit (FPU) of Execute stage, Branch Prediction Unit (BPU) of instruction fetch stage, Forwarding Unit of execution stage, Operand Logic of decode stage and Floating-Point register file of Write-back stage. These subsystems are designed using Verilog Hardware Description Language in Xilinx ISE. Followed by the implementation the verification of the floating-point unit and the forwarding unit is performed using System Verilog Assertions in QuestaSim. The Assertion coverage report for the same is extracted.

Technological Advances in Water-less Fracking: A Case Study

Hydrofracking transfigured the concept of producing from unconventional reservoirs. The Fracking fluid used in fracturing has unlocked many tight reservoirs but in terms of an aquifer, it poses threats like consumption of large quantity of water and also, used water becomes polluted as well as recycling cost is uneconomic. This paper evaluates alternatives to water-based frac fluids and discusses their environmental & economic impact along with resource availability and commercial feasibility. Pure Propane Fracturing uses propane in combination with non-toxic man-made proppants (light glass & carbon fullerene microbeads) with desired properties. Pure Propane is fluorinated and carbonated without water or harmful additives, thereby eliminates the risk of catching fire. Pure Propane Fracturing eliminates the need for water completely and thus, a perfect option for fracturing in water scarcity regions. Fracture flow capacity of Pure Propane can be enhanced with the use of phase change chemical proppants in the slurry stage. CO2 Foam Fracturing predominantly comprises liquid carbon-dioxide which reduces the water requirement up to 80%. CO2 foam-based frac fluid uses relatively fewer chemical additives as compared to the water-based frac fluid which in-turn does minimal formation damage. Foam Fracturing fluids have high fluid recovery and clean-up efficiency. CO2 foam-based frac fluid is available in a wide range of viscosities and can also work in high pressure high temperature conditions at significantly low polymer loadings. Energized frac fluid comprises N2/CO2 (20-30%) which reduces water consumption and provides additional energy to aid in load recovery during the post-frac flow-back stage. N2 gas can propagate more easily into small pores and micro-fractures to get lower breakdown pressure and enhance fracture complexity & CO2 exists in dense phase at static bottom hole conditions, thus is less susceptible to dissipation and dissolves in crude oil which reduces its viscosity and improves cleanup and recovery.
