“Media’s Influence on Enhancing Water Use Efficiency and Climate Control: Community Capacity Building in Kenya”

In recent years, the global community has witnessed the increasing impacts of climate change, resulting in various environmental challenges, including water scarcity (Stringer et al., 2021). Developing countries like Kenya are particularly vulnerable to these changes due to their heavy reliance on agriculture and limited access to water resources (Maingey et al., 2022). Addressing these challenges requires a multifaceted approach involving not only scientific and technological solutions but also community engagement and capacity building. One vital aspect of this approach is the role of media in disseminating information and fostering awareness among communities. Media platforms, including television, radio, print, and digital media, possess the unique ability to reach a broad audience and convey messages that can drive positive behavior change (Bara et al., 2021). In Kenya, where access to information is growing but remains uneven, the media can be a powerful tool to educate and empower communities regarding water use efficiency and climate control (Wutich et al., 2023). This study seeks to explore the significant role that media plays in facilitating community capacity building for enhancing water use efficiency and promoting climate control in Kenya. By examining how media channels communicate information, influence public perception, and stimulate local engagement, this research aims to uncover the various strategies employed by media to drive positive changes in water management practices and climate-conscious behaviors. Through an in-depth analysis of media campaigns, coverage, and communication strategies, this study will contribute to a better understanding of how media can effectively shape perceptions, attitudes, and actions related to water conservation and climate resilience (Ali et al., 2023). The insights gained from this research could inform policy recommendations and practical interventions that leverage the power of media for sustainable community development in Kenya and potentially serve as a model for other regions facing similar challenges.

МАНИПУЛЯЦИЯ КАК НЕТРАНСАКЦИОННАЯ ПЕРЛОКУЦИЯ

In the modern information society, access to information and means of communication has become easier and more widely available, which creates a more vulnerable environment for manipulation. This article examines the phenomenon of manipulation (to manipulate) as a non-transactional perlocution. The research methodology includes content analysis of the literature, definition of key concepts, and contextual analysis to determine the characteristics of manipulation as a non-transactional perlocution. Manipulation by us is considered as a perlocution in which the recipient allegedly cannot take part (unlike such perlocutions as convincing or charming). The concepts of persuasion, manipulation and zombification are revealed and their use in media discourse is compared with the medieval expressions of seduction and darkening. The role of demons, which in medieval texts influence people in such a way that they cannot free themselves from the power of evil, is today partly prescribed to the media and the Internet. However, the assertion of media power should not serve as an excuse for the evil feelings, beliefs and actions of recipients. Manipulation can be blocked by the recipient if he self-critically asks himself whether the influence of his media consumption leads to evil. Disclosure of these issues will allow us to more deeply understand the nature of manipulation as a non-transactional perlocution and come closer to solving the issues of promoting media literacy as a tool to counter manipulation, and develop practical recommendations for improving public safety and the effectiveness of communication.

Agriculture Residue based Electric Power Generation

The foundation of a country’s sustainable economic development rests on the availability of an ample supply of electrical energy. To remain competitive on the global stage, India must ensure the provision of sufficient electricity infrastructure to fuel its economic progress. Achieving developed nation status necessitates extending electricity access to every corner of the country. India, being primarily an agrarian nation, possesses abundant agricultural waste resources. This wealth of agricultural waste presents a valuable opportunity for electricity generation. Notably, agricultural husk emerges as a promising raw material for electricity generation, provided it undergoes proper and systematic processing. This endeavor aims to introduce the concept of electricity generation from agricultural husk, with a particular focus on rural areas in India. Agricultural husk-based small and medium power plants offer a pragmatic solution for generating and distributing electricity to underserved rural communities. Within this paper, we delve into the availability of agricultural husk resources in India, explore various feasibility studies, and elucidate the principal processes for generating electricity from rice husk. The overarching goal is to support India’s journey towards future development. This paper serves as a valuable resource for both governmental and private sector entities interested in establishing agricultural husk-based power plants in rural India. Ultimately, we aspire for this document to serve as a practical guideline for addressing the substantial electricity demand prevalent in India’s rural areas.

Optimization of electrical properties and radio frequency applications of GeTe thin film

GeTe belongs to a chalcogenide phase change material, which can dynamically achieve reversible switching between the crystalline state of low resistivity and the amorphous state of high resistivity by utilizing the thermally induced phase change characteristics. The GeTe is an important functional material in the fields of memristors and nonvolatile radio frequency (RF) switches. For RF switch applications, this paper focuses on optimizing the electrical performance of GeTe thin films prepared by magnetron sputtering. By comprehensively analyzing the effects of substrate materials, sputtering conditions, and annealing conditions on the resistivity of crystalline GeTe films, effective conditions for preparing low resistivity GeTe films are explored. Fig. (a) shows that compared with the GeTe film on a SiO<sub>2</sub> substrate, the film on an Al<sub>2</sub>O<sub>3</sub> substrate can obtain higher crystallinity and lower resistivity. For the deposition power and pressure shown in Fig. (b), the combination of medium power (50–80 W) and low pressure (2–3 mTorr) is beneficial for low crystalline resistivity of GeTe film. Additionally, Fig. (c) shows that higher annealing temperature (350–400 ℃) can realize lower film resistivity. Finally, the experimental results show that the lowest crystalline resistivity of the prepared GeTe thin film reaches 3.6×10<sup>–6</sup> Ω·m, and the resistance ratio is more than 10<sup>6</sup>. Based on rectangular chips of GeTe film, a parallel millimeter-wave switch with zero static power is also constructed. As shown in Fig. (d), the insertion loss is less than 2.4 dB, and the isolation is greater than 19 dB in a 1–40 GHz frequency band, demonstrating the potential application of GeTe thin films in the field of broadband high-performance discrete nonvolatile RF switches.

The Empirical Study over Identity Construction (Liminal Status) in Social-Media among China and UK

Lesbians, being a marginalized group, encounter challenges in constructing their identity from the past to the contemporary era. Nevertheless, aided by the power of social media, lesbians possess the ability to authentically express themselves and amplify their voices, as they are often excluded from mainstream media. The social and cultural environments in China and the UK diverge when it comes to attitudes towards homosexuality, and their respective construction of identity, which is the liminal status, on social media reflects distinct societal tendencies through varying linguistic features and focal points. The empirical study delves not only into the discourse of lesbians, but also explores the intricate psychological dynamics underlying their identity construction. Unraveling the essence of their profound motivation in identity construction not only bring about value to academic realm but help us better understand this minority from two countries and take measure to help in practice.

The Portrait of Villain in Horror Movie Await Further Instructions

This research aims to describe the portrait of the villain in the horror movie Await Further Instructions with a formulaic approach by J. G. Cawelti to provide an overview of movie development, especially the villain elements in horror movies. The descriptive-qualitative method was used in this research. The data for this research were collected by watching, pausing, identifying, classifying, and then analyzed by presenting, describing, and interpreting the data as well as concluding the analysis result. This research found four villain elements that are the same as horror villains in general (convention) and two different elements of villain (invention) that depict new sources of fear, such as motive antagonist (constructed by the media) and iconic symbol (mass media). The researcher concluded that in the horror movie Await Further Instructions, there is development in the elements of the villain that depict or represent people today being more afraid of mass media power than supernatural or unexplainable powers, such as ghosts, aliens, monsters, serial killers, and others.

Making Gender Crises: State Newspapers and the Regulation of Gender Nonconformity in China

Abstract Media coverage about transgender and gender nonconforming people both maintains and influences normative ideas about sex, gender, and sexuality. However, how state propaganda apparatus reifies these ideas through media and contributes to gender regulations remains underexplored, especially for state-dominated media systems. To bridge this gap, this article examines the media framing of gender nonconformity in China through a content analysis of 154 state-run newspaper articles from 1980 to 2021. Our analysis reveals that state newspapers introduce gender nonconformity into the purview of governance through two processes: 1) By pushing medicalized and socialization explanations for gender nonconformity, state newspapers consolidated two categories of gender nonconformity—intersex/transgender people and gender nonconforming youth. 2) State newspapers have developed two “gender crisis” frames that positioned the management of gender nonconformity at the heart of state governance and national development. Through this, gender nonconformity becomes legible for state institutions in criminal justice, medicine, marriage, education, and media. The findings contribute to the literature on media maintenance of the sex/gender/sexuality system by demonstrating the productive power of state-run media in shaping knowledge, discourse, and the regulation of gender nonconformity.

Stages of Media Studies Development in Western Sociology: Formation of Propaganda Models and Their Influence on Changes in the Public Mass Consciousness

At the end of the 1920s and the beginning of the 1930s, scientists became interested in the media as a subject of research, and there was also a concrete practical implementation of the technologies of mass media influence in political life. The defining feature of this period was the limitless power of the mass media to influence human behavior through persuasion, and the impetus for such conclusions was given by the successes of the Entente states in the First World War. Also, the targeted influence of the media on the public and the development of the PR system helped not only the American presidents to influence the domestic audience in the USA and beyond, but also the large-scale propaganda influence helped A. Hitler comes to power. At the first stage of the study of mass communications and the theory of propaganda, two scientific directions are distinguished: the Chicago school of pragmatism, represented by American researchers, and the Frankfurt school, which was developed by European scientists. Analysis of their research demonstrated the superiority of one-way communication, and the means of mass-communication influence was the power of persuasion, with the help of which the audience was deprived of critical thinking and turned into passive participants in communication. This laid the foundation for the first theories of propaganda, which were effectively used to achieve foreign policy goals by the then leaders.

A parallel input parallel output current fed front end DC‐DC converter‐based solid state transformer utilised in grid connected mode PV applications

AbstractThe presented work operated a PIPO Current fed front end converter‐based solid‐state transformer (SST) for maximum power point tracking (MPPT) and voltage boost operation in medium power range PV applications. The proposed system employed the perturb and observe (P&O)‐based MPPT technique and upheld the ZVS and ZCS operations of all primary side switches and secondary side rectifier diodes, respectively. The proposed system introduced a new fundamental extractor titled ‘Pre‐filter double fundamental signal extractor (DFSE) based multi‐layered DFSE (p‐DFSE‐MDFSE)’ and utilised it in the grid controller for synchronisation and harmonics mitigation operation. The primary goal was to achieve a compact size, reduced weight and cheaper magnetic component‐based front‐end converter of SST on the PV array side and a fast, secure and trustworthy mitigation control of current harmonics on the utility grid side. The proposed system was inspected on the OPAL‐RT (RT‐LABv2021.3.2.307) platform for various grid anomalies, and its conduct was found to be well within the IEEE 519 norms.

Power of Social Media in Political Marketing – An India Based Empirical Study

This study aims to understand the importance of different factors of social media, along with relevant demographic variables of voters to predict a voter’s preferred political brand, in the context of the Indian Lok Sabha elections. To identify the relevant demographic variables, we have gone through previous literature. However, due to the lack of substantial India-based academic literature that could help us to identify the important factors of social media campaign, we referred to US-based academic literature and attempted to obtain the superset of social media impact variables. Thereafter, we conducted focussed group discussions to identify the most important attributes, which we’ve used in our survey study. We have chosen greater Kolkata to conduct the survey. We have used multinomial logistic regression model with voters’ preferred political brand as a dependent variable with four choices. We observed that there is no significant difference between the intercept and final (including all predictors) model and also found that no individual demographic and social media impact variables are significant predictors of voters’ preferred political brand. We also measured comparative effect on different political parties for each independent variable. That would help political marketers to target specific segments with effective communication and campaign plan.

Numerical-field analysis of the magnetic conductivity of the slot dispersion of the stator winding of induction motors

Introduction. The magnetic fields and the corresponding magnetic conductivities of the slot dispersion of the stator winding of three-phase induction motors (IM) are studied. Such studies are relevant in their design and are one of the bases for calculating a number of energy parameters and characteristics of motors. In the classical design of an IM, which is still valid, the specified magnetic conductivities are determined analytically according to the simplified slot dispersion model, therefore they may not always provide sufficient accuracy due to a number of assumptions and conventions. Goal. Further development of the IM design system by means of a numerical-field calculation analysis of the magnetic conductivity of the slot dispersion of their stator winding, as well as a comparative check of the relevant analytical formulas from various methods of classical design. Results. The slot dispersion of IM is determined by numerical calculations using the FEMM program within the stator tooth steps. For the research, four variants of the shapes of the stator slots, which are common in modern IMs of small and medium power, are accepted. In the calculations, calculation models with strongly saturated and unsaturated in the magnetic relation with the stator core teeth are considered. The numerical-field method shows that the classical design method can give both sufficiently accurate results and unacceptable errors in determining the magnetic conductivities of slot dispersion of IM. Discussion and prospects for further development. The provided numerical-field analysis method and the obtained results of the calculation of slot dispersion of IM windings are recommended as a basis for improving the system of their design.

Comprehensive assessment of the quality of laminated core of electrical machines by the high-frequency induction-vibration method

In this work, the problem of assessing the quality of active parts of electric machines, in particular charged magnetic conductors, is considered. The essential diagnostic indicators of the actual state of the recruitment core were determined, namely specific losses during remagnetization and weakening of package pressing, which are associated with increased losses, decreased efficiency, violation of the thermal regime, etc. induction-measuring module for determining the level of inter-sheet insulation breakdown and the growth of losses in the core. It is recommended when loosening for small-sized magnetic conductors, impregnation of the weakened area with adhesive varnish and subsequent drying with a compressed core. Also, for cores of a small diameter, between the pressure washer and the extreme sheets of the core, drive textolite wedges every 2...4 teeth. When the pressing of the cores of large electric machines, in which the pressing is carried out by tension pins, is weakened, the pins are tightened. A two-dimensional field mathematical model of a charged magnetic core package was developed in order to estimate the distribution of the electromagnetic field and eddy currents and losses at different frequencies from 50 Hz to 10 kHz. It is proposed to use the analysis of the transient process when the magnetic flux changes in the magnetic circuit. To simplify the measuring scheme, it is proposed to use the process of switching the current in the excitation winding. With the help of the developed model, the calculation of transient modes was carried out on the example of the studied magnetic circuit. As an object of research, a mock-up of a stacked magnetic core was used, which is a set package of magnetic steel sheets used in magnetic cores of dry transformers of small and medium power. In order to combine the two methods, an installation was developed that allows checking the quality of pressing and the quality of inter-sheet insulation at the same time.

Turkey’s Middlepowermanship, Foreign Policy Transformation and Mediation Efforts in the Russia-Ukraine War

This article provides insight into Turkey’s strategic pursuit of a more active and influential role as a mediator in the ongoing Russia-Ukraine war. Turkey, positioning itself as a middle power, seeks to elevate its global standing. This involves a delicate diplomatic balancing act in its foreign policy approach towards both Russia and Ukraine. The equilibrium thus achieved positions Turkey as a natural mediator, serving as a catalyst for brokering a peace initiative among the conflicting parties. Ankara’s diplomatic activism is not just a tactical move but also a manifestation of Turkey’s broader global ambitions, underlining its commitment to playing a more significant role in shaping international affairs. These aspirations clash with a rising penchant in Turkey to pursue a more militaristic and coercive foreign policy, which stands in contradiction to the role of a benign power.

Theorizing virtual counterspaces: how Latina graduate students build community online

ABSTRACT In this article we extend the concept of counterspaces by theorizing an emerging form of counterspace – virtual counterspace. We employ Latine Critical Race Theory (LatCrit) and racial microaggressions to understand how Latina graduate students utilize Instagram to cultivate community online. Latina graduate students encounter unique barriers to degree attainment including lack of cultural affirmation, isolation, microaggressions, and hostile campus racial climates. Drawing on the experience of developing virtual counterspaces, we argue that virtual counterspaces are sites of cultural affirmation, community building, knowledge sharing, and empowerment that enable the academic success of Latina graduate students. Given the power of social media, we urge colleges and universities to leverage these platforms to engage and support Latinas and other Students of Color.
