    The motor-generator set is widely used in the industry for converting large amounts of power energy to a different form of energy although the topic for this project motor-generator is smaller than usually utilized by an industrial company. The primary purpose of this small version motor-generator is for learning tool used by students associated with Electrical Power Engineering or Industrial Computer System Engineering at Murdoch University. The equipment is located in 1.003 Pilot Plant Engineering & Energy Building and was used in previous years by students at Murdoch University. The fundamental aim of the project is to get the apparatus operating correctly and establish accurate communication and control. Investigate the effects of Variable Speed Drive on the motor, the effects of rotor speed and loads on the generator. To design and implement a working communication and control program in the system using LabVIEW software, it should display the following outputs; Field Voltage, Armature Voltage, Current, Power, Synchronous Speed of Motor, Rotor Speed, Force, and Torque. It will be discussed in this report the fundamentals of motor-generator, National Instrument Data Acquisition card, and the LabVIEW software that being used and also the different components used as communication for the motor-generator. The major equipment of the system that will investigate are the following; Variable Speed Drive (VSD), Induction Motor, DC Generator, and the NI DAQ card. With understanding these pieces of equipment, it would determine accurate data information in the outputs. Allen Bradley variable speed drive powered and control the induction motor’s speed, while the National Instrument Data Acquisition card receives the systems information and addresses the controls. The four-kilowatt three-phase induction motor with 415 Voltage and 7.7 Amps which runs at 1455 revolution per minute. The DC generator converts mechanical energy into electrical energy and produces the measured DC voltage output with a variable load bank. The software control for this project is LabVIEW, which reads and writes to different components of the project through NI 6013, 50 pin DAQ card. To ensure the implementation of the communication and control program, it was run with many trials that produced accurate results. The output results of Voltage, Current and Power are displayed in the waveform were expected, the Strain Gauge that measured force were also shown as well as the torque concerning the level arm of the generator. The rotor speed was calculated based on the synchronous speed and slip of the motor and not measured by a proximity sensor. The calculated values of rotor speed were compared to the tachometers measured value

    Get PDF
    Background: Folk medicine refers to traditional healing practices anchored on cultural beliefs of body physiology and health preservation. Reflective of indigenous heritage, it fosters a better understanding of health and disease, healthcare systems, and biocultural adaptation. In the Philippines, Quiapo is a well-known site for folk medicine services, cultural diversity, religious practices, and economic activities. Methods: This study utilized a phenomenological approach to comprehend the lived experiences of health-seeking individuals and the meaning behind their acquisition of folk medicine products. Using convenience sampling, seven participants acquiring folk medicine products in Quiapo on the day of data collection were approached and interviewed on separate instances. The collected data subsequently underwent thematic analysis. Results: Analysis revealed three emergent themes: health-seeking behavior, sources of knowledge, and folk medicine utilization. Health-seeking behavior was linked with the participants’ purpose of going to Quiapo, reasons for utilizing folk medicine, experiences in using folk medicine, and beliefs associated with the product bought. Sources of knowledge tackled the participants’ sources of information about Quiapo and its products. Folk medicine utilization relates to the type of product bought, its perceived medicinal use, and its history of usage. Conclusion: Folk medicine is perceived to be effective alleviating health concerns. The acquisition of such products is attributed to satisfaction from prior experience, distrust in the current healthcare system, family tradition, and intention to supplement existing medical treatment. This study provides health professionals a better understanding of patients who patronize folk medicine, subsequently aiding them in providing a holistic approach to treatment

    Multicultural mediations, developing world realities: Indians, Koreans and Manila’s entertainment media

    Get PDF
    In this article, I examine the mediation of multiculturalism in the developing world city of Manila, the Philippines. Drawing on both a thematic analysis of the Manila-centric Philippine entertainment media and six focus group discussions with the city’s local Filipinos, I reveal that this instance of mediation is entangled with the broader discourses of the Philippine postcolonial nationalist project. For one, the mediation of multiculturalism in Manila tends to symbolically marginalize the city’s Indians and Koreans and, in so doing, reinforces existing negative discourses about them. I contend that this is linked to the locals’ preoccupation with establishing a unifying cultural identity that tends to make them elide the issue of their own internal cultural diversity, as well as of the increasing diasporic population of the city. Second, the said mediation also tends to valorize the lighter-skinned Koreans over the darker-skinned Indians. I posit that this is related to how the locals’ discourse of cultural homogeneity has resulted in their continued reluctance to publicly discuss the persistence of their unspoken skin-tone-based racial hierarchy not only of themselves, but also of their cultural others

    Inter-Observer Agreement on Subjects' Race and Race-Informative Characteristics

    Health and socioeconomic disparities tend to be experienced along racial and ethnic lines, but investigators are not sure how individuals are assigned to groups, or how consistent this process is. To address these issues, 1,919 orthodontic patient records were examined by at least two observers who estimated each individual's race and the characteristics that influenced each estimate. Agreement regarding race is high for African and European Americans, but not as high for Asian, Hispanic, and Native Americans. The indicator observers most often agreed upon as important in estimating group membership is name, especially for Asian and Hispanic Americans. The observers, who were almost all European American, most often agreed that skin color is an important indicator of race only when they also agreed the subject was European American. This suggests that in a diverse community, light skin color is associated with a particular group, while a range of darker shades can be associated with members of any other group. This research supports comparable studies showing that race estimations in medical records are likely reliable for African and European Americans, but are less so for other groups. Further, these results show that skin color is not consistently the primary indicator of an individual's race, but that other characteristics such as facial features add significant information

    Is There Evidence of "Whitening" For Asian/White Multiracial People in Britain?

    Get PDF
    Growing rates of interracial unions in multi-ethnic societies such as Britain are notable, and point to significant changes in the blurring and possibly shifting nature of ethnic and racial boundaries. Asian Americans who partner with White Americans are assumed to engage in “whitening” – both in terms of their aspirations and their social consequences. Yet little is still known about the aftermath of intermarriage, even in the USA. Drawing on this US literature, this paper considers the whitening thesis in relation to multiracial people in Britain, with a particular focus on Asian/White multiracial people. I draw upon the findings of two British studies – one of multiracial young people in higher education (Aspinall & Song 2013), and another of multiracial people who are parents (Song 2017) – to explore these questions. I argue that conceptualizations of part Asian people (in the USA) as leaning toward their White heritages are often unsubstantiated, and deduced primarily from one key factor: their high rates of intermarriage with White spouses. In addition to the variable ways in which part Asian people may relate to their minority and White ancestries, we must consider the ambivalence, tensions, and contextually variable identifications and practices adopted by multiracial people

    Technological elites, the meritocracy, and postracial myths in Silicon Valley

    Get PDF
    Entre as modernas elites tecnolĂłgicas digitais, os mitos da meritocracia e da façanha intelectual sĂŁo usados como marcadores de raça e gĂȘnero por uma supremacia branca masculina que consolida recursos de forma desproporcional em relação a pessoas nĂŁo brancas, principalmente negros, latinos e indĂ­genas. Os investimentos em mitos meritocrĂĄticos suprimem os questionamentos de racismo e discriminação, mesmo quando os produtos das elites digitais sĂŁo infundidos com marcadores de raça, classe e gĂȘnero. As lutas histĂłricas por inclusĂŁo social, polĂ­tica e econĂŽmica de negros, mulheres e outras classes desprotegidas tĂȘm implicado no reconhecimento da exclusĂŁo sistĂȘmica, do trabalho forçado e da privação de direitos estruturais, alĂ©m de compromissos com polĂ­ticas pĂșblicas dos EUA, como as açÔes afirmativas, que foram igualmente fundamentais para reformas polĂ­ticas voltadas para participação e oportunidades econĂŽmicas. A ascensĂŁo da tecnocracia digital tem sido, em muitos aspectos, antitĂ©tica a esses esforços no sentido de reconhecer raça e gĂȘnero como fatores cruciais para inclusĂŁo e oportunidades tecnocrĂĄticas. Este artigo explora algumas das formas pelas quais os discursos das elites tecnocrĂĄticas do Vale do SilĂ­cio reforçam os investimentos no pĂłs racialismo como um pretexto para a re-consolidação do capital em oposição Ă s polĂ­ticas pĂșblicas que prometem acabar com prĂĄticas discriminatĂłrias no mundo do trabalho. Por meio de uma anĂĄlise cuidadosa do surgimento de empresas de tecnologias digitais e de uma discussĂŁo sobre como as elites tecnolĂłgicas trabalham para mascarar tudo, como inscriçÔes algorĂ­tmicas e genĂ©ticas de raça incorporadas em seus produtos, mostramos como as elites digitais omitem a sua responsabilidade por suas reinscriçÔes pĂłs raciais de (in)visibilidades raciais. A partir do uso de anĂĄlise histĂłrica e crĂ­tica do discurso, o artigo revela como os mitos de uma meritocracia digital baseados em um “daltonismo racial” tecnocrĂĄtico emergem como chave para a manutenção de exclusĂ”es de gĂȘnero e raça.Palavras-chave: Tecnologia. Raça. GĂȘnero.Among modern digital technology elites, myths of meritocracy and intellectual prowess are used as racial and gender markers of white male supremacy that disproportionately consolidate resources away from people of color, particularly African Americans, Latino/as and Native Americans. Investments in meritocratic myths suppress interrogations of racism and discrimination even as the products of digital elites are infused with racial, class, and gender markers. Longstanding struggles for social, political, and economic inclusion for African Americans, women, and other legally protected classes have been predicated upon the recognition of systemic exclusion, forced labor, and structural disenfranchisement, and commitments to US public policies like affirmative action have, likewise, been fundamental to political reforms geared to economic opportunity and participation. The rise of the digital technocracy has, in many ways, been antithetical to these sustained efforts to recognize race and gender as salient factors structuring technocratic opportunity and inclusion. This paper explores some of the ways in which discourses of Silicon Valley technocratic elites bolster investments in post-racialism as a pretext for re-consolidations of capital, in opposition to public policy commitments to end discriminatory labor practices. Through a careful analysis of the rise of digital technology companies, and a discussion of how technology elites work to mask everything from algorithmic to genetic inscriptions of race embedded in their products, we show how digital elites elide responsibility for their post-racial re-inscriptions of racial visibilities (and invisibilities). Using historical and critical discourse analysis, the paper reveals how myths of a digital meritocracy premised on a technocratic colorblindness emerge key to perpetuating gender and racial exclusions.Keywords: Technology.

    “Charming Eyes”: Exploring Agency through the Beauty and Makeup Practices of Salesladies in Metropolitan Manila’s Department Stores

    No full text
    An examination of the role and meaning of beauty and makeup practices among the salesladies of Metropolitan Manila’s department stores brings forth a worker-centered analysis of “agency” using the notion of “charming eyes.” Here, we find an intimate blending of the practices of working as a saleslady: how compliance  with the company’s “appearance rules” and “beauty standards” serve the interests of retail businesses and are not merely expressions of individuality. Simultaneously, this analysis addresses concerns about working and pursuing their goals, desires, and aspirations in life. Through the ethnographic approach, this study was comprehensively contextualized through the everyday lived experiences of  acting subjects within the setting, thereby capturing their rich voices. Data sources include interviews, life narratives, observations, photo documentation, material object analysis, and secondary research. I argue that the emergence of “agency” is context specific: to reveal “agency” is to understand the context and how practices correspond with the limits and possibilities therein. The salesladies’ “agency” was manifested in the beauty and makeup practices as they enacted work with their respective mobility—social, cultural, economic—projects in mind. This view subverts the usual low-pay, low-status, and lowprestige associations of the occupation. As a counter-narrative, the article shows a specific group of workers making sense of their work conditions as they try to meaningfully engage its constraints and transform their lives on their terms (Ortner 2006)

    The Filipino Question in Asian and Pacific Islander America: Rethinking Regional Origins in Diaspora

    No full text
    About the book: Pacific Islander Americans constitute one of the United States\u27 least understood ethnic groups. As expected, stereotypes abound: Samoans are good at football; Hawaiians make the best surfers; all Tahitians dance. Although Pacific history, society, and culture have been the subjects of much scholarly research and writing, the lives of Pacific Islanders in the diaspora (particularly in the U.S.) have received far less attention. The contributors to this volume of articles and essays compiled by the Pacific Islander Americans Research Project hope to rectify this oversight. Pacific Diaspora brings together the individual and community histories of Pacific Island peoples in the U.S. It is designed for use in Pacific and ethnic studies courses, but it will also find an audience among those with a general interest in Pacific Islander Americans
