Management Practices and Holistic Development of Dance Troupe in Selected Secondary Schools

Management is a procedure of designing and sustaining an environment where everyone works together to attain the organization's goal. The study is a comparative analysis of the management practices of selected secondary public schools' dance troupe. This study is primarily anchored to the Skills Acquisition Theory (SAT). Specifically,  the aims to identify the management practices and holistic development of the dance troupe members. The research study wants to determine the procedures in terms of rehearsals and training, community involvement, qualification of dancers, facilities, financial support, and the level of dancers' attributes in terms of attitude, discipline, and skills. The researcher also wants to determine if there is a significant relationship between the management practices and holistic development on the personal attributes of dance troupe members of the selected secondary public schools. Using a descriptive-quantitative methodology, a self-administered questionnaire was utilized in the survey of 172 dancers. The results revealed that dancers are well-disciplined and highly skilled. The management of the dance troupe struggles in terms of qualifications of the members, facilities, and financial support, which ultimately affect their preparation and training programs. Hence, there is a significant relationship between the management practices and holistic development of dance troupe members. The dance troupe's practices, skills, attitudes, and discipline have to maintain

AMERICANS AND GM FOOD: KNOWLEDGE, OPINION AND INTEREST IN 2004

This report presents the results from the third in a series of studies examining public perception of genetically modified (GM) food in the United States. All three studies were based on survey results of separate, nationally representative samples of approximately 1,200 Americans taken in 2001, 2003, and 2004. While the survey instrument on which the current report is based maintained many of the same measures of awareness and attitude as its two predecessors, it also included several new queries that assess the ability of respondents to recall specific news stories related to GM food, their interest in the topic, and where they would go to look for new information. Many questions that were repeated from previous years have changed considerably in the current survey. Some of the classic measures of awareness and opinion now incorporate an "unsure" response as choice supplied by the interviewer. While respondents were allowed to volunteer this response in the past, explicitly providing this option to respondents reduced guessing on knowledge-based questions and encouraged a more accurate representation of opinion than in the past. The report begins with an investigation of Americans' awareness and knowledge about the topic in general, their ability to recall related news stories, familiarity with laws and regulations as well as other questions designed to get at highly specific knowledge about agricultural biotechnology. Next, it details the effect of the new survey methodology on reported opinions about plant-based and animal-based GM food. Finally, it delves into a number of novel findings about interest in hypothetical television shows about GM food, desire for information on food labels, and reported behavior with regards to information seeking. Consistent with results from our previous studies and others, these findings suggest that the American public is generally unaware of GM food. Most Americans have heard or read little about it, are not aware of its prevalence in their lives, and are confused as to which type of GM products are available. Respondents struggled with factual questions related to GM food and the science behind it, could not recall news stories related to the topic, and were not very knowledgeable about laws regarding the labeling and testing of GM food. Americans are also unsure of their opinions about GM food and split in their assessments of the technology when forced to take a position. Americans say they are interested in the topic of GM food, specifically those topics related to human health. Respondents say they desire more information on food labels and report that they would like to see GM foods labeled as such. The majority of Americans admit they have never looked for information about GM food and most say they will search the Internet should the need arise.Research and Development/Tech Change/Emerging Technologies,

Evaluation of the integration of the Wind-Induced Flutter Energy Harvester (WIFEH) into the built environment: experimental and numerical analysis

With the ubiquity of low-powered technologies and devices in the urban environment operating in every area of human activity, the development and integration of a low-energy harvester suitable for smart cities applications is indispensable. The multitude of low-energy applications extend from wireless sensors, data loggers, transmitters and other small-scale electronics. These devices function in the microWatt-milliWatt power range and will play a significant role in the future of smart cities providing power for extended operation with little or no battery dependence. This study thus aims to investigate the potential built environment integration and energy harvesting capabilities of the Wind-Induced Flutter Energy Harvester (WIFEH) – a microgenerator aimed to provide energy for low-powered applications. Low-energy harvesters such as the WIFEH are suitable for integration with wireless sensors and other small-scale electronic devices; however, there is a lack in study on this type of technology’s building integration capabilities. Hence, there is a need for investigating its potential and optimal installation conditions. This work presents the experimental investigation of the WIFEH inside a wind tunnel and a case study using Computational Fluid Dynamics (CFD) modelling of a building integrated with a WIFEH system. The experiments tested the WIFEH under various wind tunnel airflow speeds ranging from 2.3 to 10 m/s to evaluate the induced electromotive force generation capability of the device. The simulation used a gable-roof type building model with a 27° pitch obtained from the literature. The atmospheric boundary layer (ABL) flow was used for the simulation of the approach wind. The work investigates the effect of various wind speeds and WIFEH locations on the performance of the device giving insight on the potential for integration of the harvester into the built environment. The WIFEH was able to generate an RMS voltage of 3 V, peak-to-peak voltage of 8.72 V and short-circuit current of 1 mA when subjected to airflow of 2.3 m/s. With an increase of wind velocity to 5 m/s and subsequent membrane retensioning, the RMS and peak-to-peak voltages and short-circuit current also increase to 4.88 V, 18.2 V, and 3.75 mA, respectively. For the CFD modelling integrating the WIFEH into a building, the apex of the roof of the building yielded the highest power output for the device due to flow speed-up maximisation in this region. This location produced the largest power output under the 45° angle of approach, generating an estimated 62.4 mW of power under accelerated wind in device position of up to 6.2 m/s. For wind velocity (UH) of 10 m/s, wind in this position accelerated up to approximately 14.4 m/s which is a 37.5% speed-up at the particular height. This occurred for an oncoming wind 30° relative to the building facade. For UH equal to 4.7 m/s under 0° wind direction, airflows in facade edges were the fastest at 5.4 m/s indicating a 15% speed-up along the edges of the building

Engaging Students through Video: Integrating Assessment and Instrumentation

CS50 is Harvard’s introductory course for majors and non-majors alike. For years, we have posted videos of the course’s lectures and sections online for the sake of review and distance education alike. But students’ experience with these videos has been historically passive. Students have been able to watch the course’s content on demand, rewinding and fast-forwarding at will, but they have not had means to engage interactively with the content or to check their understanding of material while watching videos. Furthermore, while we collected basic usage data (e.g., how many times a video was viewed), we lacked detailed analytics describing, for example, which portions of a video were commonly skipped or watched multiple times by students. To make videos more immersive and engaging for students, we developed CS50 Video, an open-source video player for desktop and mobile devices. CS50 Video allows instructors to integrate assessment questions to be answered by students at their own pace or at specific points in time directly into a video player. CS50 Video also allows students to search over video transcripts to find content easily as well as view videos at variable playback speeds (in order to make videos more accessible for ESL learners). Finally, CS50 Video integrates with third-party analytics solutions to allow instructors to view detailed usage statistics describing how students are interacting with videos (e.g., which videos or portions of videos are commonly watched or skipped over). We have deployed CS50 Video to students taking CS50 online and have obtained preliminary results. Because CS50 Video stores responses to questions server-side, we have been able to track students’ performance on in-video assessments. Thus far, we have observed that only 28% of students who watch online videos have engaged with assessment questions. Students who answer an assessment question incorrectly on their first attempt will often try again until reaching a correct answer, with 84.5% of correct answers reached in at most three attempts. We next plan to analyze the effects of in-video assessments on students’ mastery of material and introduce A/B-testing functionality for questions. We also plan to use students’ performance on assessments to understand the topics with which students struggle.Engineering and Applied Science

The Effect of Topical Cannabidiol on the Progression Rate of Delayed Onset Muscle Soreness

International Journal of Exercise Science 16(3): 1426-1439, 2023. This study investigated the efficacy of topical cannabidiol (CBD) ointment in reducing localized inflammation, minimizing performance detriments, and attenuating soreness associated with delayed onset muscle soreness (DOMS). In a double blind randomized control trial, upper-arm circumferences, maximal voluntary isometric contractions (MVICs) for elbow flexion at 90° and 30° for college-aged participants (n = 21, age 20.8 ± 1.9 years) were assessed at baseline. Participants then performed a DOMS-inducing protocol for the biceps brachii. Topical CBD ointment and placebo (P) ointment were randomly assigned and applied 30 minutes, 24, 48 and 72 hours post the DOMS protocol. The baseline parameters and a visual analog scale (VAS) to assess perceived soreness were assessed 24, 48 and 72 hours post DOMS protocol. A 4x2 repeated measures factorial ANOVA (P \u3c 0.05) analyzed both within and between subject differences. No changes were statistically significant on any days between conditions: Upper-arm circumferences in the CBD arm (7.1 ± 5.8 cm) and in the P arm (7.3 ± 5.8 cm). MVICs were reduced at both the 90° and 30° positions (-5.9 ± 9.0 Nm (90°)); (-4.8 ± 6.5 Nm (30°)) and the P arm (-5.0 ± 10.0 Nm (90°)); (-4.6 ± 5.3 Nm (30°)). Soreness increased in both the CBD arm (6.1 ± 2.1) and the P arm (5.5 ± 2.6) over time. Topical CBD therefore did not alter any parameters vs the P treatment, thus the use of topical CBD does not attenuate the effects of DOMS

O que Hegel diria da nossa cordialidade?

For Hegel, freedom presupposes norms and impersonal institutions are indispensable in the mediation of intersubjective relations. Sérgio Buarque de Holanda explains how the cordial subjects deal with difficulty with the normative constraints trying to make them more flexible or to circumvent them. We intend to explain how and for what causes we develop a type of sociability averse to impersonal normativity, prioritizing direct personal contact and intimacy.  Para Hegel a liberdade pressupõe normas e as instituições impessoais são indispensáveis na mediação das relações intersubjetivas. Por sua vez Sérgio Buarque de Holanda explica como os sujeitos cordiais lidam com dificuldade com as coerções normativas visando flexibilizá-las ou burlá-las. Pretendemos explicar como e por quais motivos desenvolvemos um tipo de sociabilidade avesso a normatividade impessoal, priorizando o contato pessoal direto e a intimidade

SOCIABILIDADE NA FILOSOFIA POLÍTICA DE HEGEL: SUPERAÇÃO DA ABORDAGEM GREGA E MODERNA

Para os gregos a universalidade era a condição necessária para a sociabilidade; para os modernos era a particularidade o fundamento da sociabilidade. É a partir da resolução dessa contradição que Hegel desenvolve sua ética e filosofia política para o qual a relação de reciprocidade entre universalidade e particularidade é a conditio sine qua non da sociabilidade. O presente artigo se propõe esclarecer a resposta de Hegel acerca de qual seria o fundamento da sociabilidade e sua solução dialética a questão ao resolver as contradições entre à perspectiva dos gregos e dos modernos

Effect of urban street canyon aspect ratio on thermal performance of road pavement solar collectors (RPSC)

Studies on RPSC (road pavement solar collectors) have shown the potential of reducing the urban heat island effect by dissipating the heat from the pavement for energy harness. In our previous work, performance analysis of RPSC system was carried out to compare the RPSC embedment in two scenarios; within an urban street canyon and within suburban or rural area. The current study expands the analysis of the RPSC system in urban areas by assessing the impact of varying canyon aspect ratios on the performance of RPSC. De-coupled Computational Fluid Dynamic (CFD) approach was proposed to investigate the integration of RPSC system in an urban canyon. The CFD tool ANSYS Fluent 15.0 was used to simulate the fluid flow and heat transfer on the pavement/road surface by enabling three models: (i) energy model, (ii) standard k-epsilon model, and (iii) coupled DO-solar load radiation model. The results showed that a significant pavement surface temperature increase was found when the aspect ratio (AR) was increased from 1 to 2 while minimal increase was observed for the canyon with AR above 2. At the particular simulated time (13:00) and location, it was found that the overall performance of the RPSC system significantly increased by up to 13.0 when AR was increased from 1 to 2, but the performance of RSPC in shadow area (due to the shading effect of building) had significantly dropped (up to 30.0) from AR 3 to 4. Findings of this study showed that the canyon aspect ratio had a significant impact on the temperature distribution of the ground surface and should be taken into consideration when assessing the performance of RPSC in urban areas

A user-controlled thermal chair for an open plan workplace: CFD and field studies of thermal comfort performance

This study aims to improve user comfort and satisfaction regarding the thermal environment in the open plan office, which is a current challenge in the workplace addressed by limited research. The main difficulty in an open plan setting is that changing the room temperature in an area affects all occupants seated nearby. This issue in addition to individual differences in perceiving the thermal environment create a great challenge to satisfy all occupants in the workplace. This study investigates the application of an advanced thermal system, a user-controlled thermal chair, which allows individual control over their immediate thermal environment without affecting the thermal environment and comfort of other occupants. The performance of the chair was further analysed through Computational Fluid Dynamics (CFD) simulations providing a detailed analysis of the thermal distribution around a thermal chair with a sitting manikin. The results indicated that user thermal comfort can be enhanced by improving the local thermal comfort of the occupant. A prototype of an office chair equipped with thermal control over the seat and the back was produced and examined in an open plan office in November in Leeds, UK. Forty-five individuals used the chair in their everyday context of work and a survey questionnaire was applied to record their views of the thermal environment before and after using the chair. The results of the field study revealed 20% higher comfort and 35% higher satisfaction level, due to the use of thermal chair. Thermal measurements showed acceptable thermal conditions according to the ASHRAE Standard 55-2013. Over 86% of the occupants set the temperature settings of the seat and the back of the chair between 29 °C and 39°. 82% of the occupants expressed their satisfaction level as “satisfied” or “very satisfied” regarding the performance of the thermal chair. The thermal chair energy consumption was relatively low (0.03 kW) when compared with that of typical personal heaters, which are about 1–1.5 kW. Further research is recommended to improve the design and application of the thermal chair to improve user overall thermal comfort and also further reduce energy consumption

A review of numerical modelling of multi-scale wind turbines and their environment

Global demand for energy continues to increase rapidly, due to economic and population growth, especially for increasing market economies. These lead to challenges and worries about energy security that can increase as more users need more energy resources. Also, higher consumption of fossil fuels leads to more greenhouse gas emissions, which contribute to global warming. Moreover, there are still more people without access to electricity. Several studies have reported that one of the rapidly developing source of power is wind energy and with declining costs due to technology and manufacturing advancements and concerns over energy security and environmental issues, the trend is predicted to continue. As a result, tools and methods to simulate and optimize wind energy technologies must also continue to advance. This paper reviews the most recently published works in Computational Fluid Dynamic (CFD) simulations of micro to small wind turbines, building integrated with wind turbines, and wind turbines installed in wind farms. In addition, the existing limitations and complications included with the wind energy system modelling were examined and issues that needs further work are highlighted. This study investigated the current development of CFD modelling of wind energy systems. Studies on aerodynamic interaction among the atmospheric boundary layer or wind farm terrain and the turbine rotor and their wakes were investigated. Furthermore, CFD combined with other tools such as blade element momentum were examined
