Impact of internal shading controls on efficient daylighting in home-office workspaces in tropical climates
No full textHome office workspaces have significantly grown in residential sectors throughout the world. Nowadays, many people worldwide are forced to work from their housing units due to the outbreak of the COVID-19 pandemic. However, the existing residential buildings were only designed for living activities, not for desk-related tasks. This is more critical in tropical regions with the overabundance of indoor daylight and lack of external shadings on existing buildings. Despite the limitations for modifying the external facades, interior retrofit plays a major role in improving visual environments. Daylighting performances of various configurations, including internal shading devices, interior surfaces, and window films, were experimented with the Radiance-IES program. A field measurement of daylight was conducted in a home office room under the Malaysian tropical sky to validate the simulated results. This research proved that the existing residential buildings in the tropical climates had poor daylighting performance where the mean indoor illuminance could be over 10,000 lx. The combination of a light shelf, a partial blind, and the tinted window film could effectively 85% alleviate the excessive indoor daylight level. This configuration recorded a significant improvement in Useful Daylight Zone (around 300%), and Daylight Glare Probability was considerably reduced from 0.46 to 0.34
Using Hip-Hop Culture to Engage in Culturally Relevant Literacy Instruction
Get PDFThe COVID-19 pandemic along with Black Lives Matter have both cast a spotlight on inequities that exist racially, and the glaring disparities in the digital divide that exist in our culture today. With student demographics changing across the nation, these issues have created a need for educators to effectively meet the needs of a diverse student population that is and continues to change. Schools and classrooms need to be culturally responsive using the cultural knowledge, prior experiences, and learning styles of diverse students to make learning more engaging and effective more than ever. Culturally responsive literacy instruction bridges the gap between the school and the student\u27s world. Using hip-hop culture in literacy instruction encourages teachers to adapt their instruction to meet the learning needs of all students by providing literacy instruction that is culturally responsive and promotes high achievement among culturally diverse students. According to Broughton (2017), hip-hop culture is communication identified through artistic, musical, physical, and visual modes that people use to express their experiences, beliefs, and emotions. Rap music (spoken or chanted rhyming lyrics performed in time to a beat) is one of the four key stylistic elements of hip-hop culture, in addition to deejaying/scratching, break dancing, and graffiti writing (word art)
Maximum Difference Extreme Difference Method for Finding the Initial Basic Feasible Solution of Transportation Problems
Get PDFA Transportation Problem can be modeled using Linear Programming to determine the best transportation schedule that will minimize the transportation cost. Solving a transportation problem requires finding the Initial Basic Feasible Solution (IBFS) before obtaining the optimal solution. We propose a new method for finding the IBFS called the Maximum Difference Extreme Difference Method (MDEDM) which yields an optimal or close to the optimal solution. We also investigate the computational time complexity of MDEDM, and show that it is O(mn)
Memory Response of Magneto-Thermoelastic Problem Due to the Influence of Modified Ohm’s Law
Get PDFIn this article, in the form of the heat conduction equation with memory-dependent-derivative (MDD), a new model in magneto-thermoelasticity was developed with modified Ohm’s law. To obtain the solutions, normal mode analysis is used. The obtained solution is then exposed to time- dependent thermal shock and stress-free boundary conditions. The effect of the modified Ohm’s law coefficient, time-delay, and different kernel functions under the magnetic field effect on different quantities are evaluated and observed graphically on all field variables
Digital Shame, Dehumanization, and Dismissal: An Analysis of Gender Policing
Get PDFIntroduction: The online performance of gender provides a unique glimpse at how individuals manipulate digital settings to reflect their engagement with their own gender performance and the gender performance of others. The majority of gender performance occurs subconsciously and is learned through repeated engagement with gendered expectations. However, the performativity of gender is brought to individuals’ consciousness when they are confronted with individuals who perform in a way that contrasts with previously held gender expectations. Transgender and gender-nonconforming individuals face frequent and often harsh gender policing that attacks them for their deviation from performances that are socially “acceptable.”
Methods: An ethnographic research project was conducted by recording observations of individuals’ interaction with, and response to, gender performances on the NBC News Instagram feed. Particular instances where the performativity of gender becomes a conscious engagement for users were detailed, and their reactions to different performances of gender were analyzed.
Results and Conclusion: Eleven posts with a collective 2,331 comments were analyzed throughout this research. An overwhelming majority of the comments observed implemented one of the three gender policing strategies outlined above. In the three comment sections with the least instances of gender policing, the rate of gender policing in the comments hovered around 50%, with roughly half of the comments utilizing one of the strategies of gender policing and the other half affirming the messages communicated by the post. For the other eight comment sections analyzed, comments that utilized gender policing strategies constituted roughly 75-80% of the comments. Across all eleven posts, 51 comments were utilized for a deeper analysis of the dynamics of gender policing online. While the three strategies of gender policing that will be discussed in this paper are by no means the only forms of gender policing observed on the NBC News Instagram feed, these strategies encompass a wide range of comments and appear the most frequently.
Gender policing occurs as a defensive response to gender performances that subvert expectations and draw prominence to the performativity that gender is. When trying to attack someone for contrasting gendered expectations, there are three main ways to accomplish this: try to make them feel bad about their gender performance, warrant harm towards them as a consequence of the “offensiveness” of their gender performance, or label their gender performance as invalid. These three defense mechanisms translate into the shame strategy, the dehumanization strategy, and the dismissal strategy. Future studies should investigate how gender is policed and if these strategies are consistent across news platforms, regardless of political leaning. Additionally, future studies evaluate how gender policing on the Instagram pages of news sites compares to gender policing on personal Instagram pages
Patterns of nutrient dynamics within and below the rootzone of collard greens grown under different organic amendment types and rates
No full textThe knowledge about nutrient dynamics in the soil is pivotal for sustainable agriculture. A comprehensive research trial can retort unanswered questions. Dynamics of nutrients sourced from organic amendment types (chicken manure, dairy manure, and Milorganite™) applied at different rates (0, 168, 336, 672 kg total N/ha) were monitored within and below the rootzone of collard greens cultivated on a sandy loam soil in Prairie View, TX, USA. Macro-and micronutrients (e.g., TN: total nitrogen, P: phosphorous, K: potassium, Na: sodium, Ca: calcium, Mg: magnesium, B: boron, Cu: copper, Fe: iron, and Zn: zinc) were analyzed from soil solution samples collected during six sampling periods from within and below the rootzone. As hypothesized, the organic amendment types and rates significantly (p \u3c 0.05 and/or 0.01) affected nutrient dynamics within and below the crop rootzone. Chicken manure released significantly more TN, P, K, Na, Ca, Mg, B, Cu, and Fe than the other two amendments. The application of chicken manure and Milorganite™ resulted in higher below-the-rootzone leachate concentration of TN, Na, Mg, and Ca than in the leachates of dairy manure. Dairy manure treatments had the lowest concentrations of TN, Ca, and Mg; whereas, Milorganite™ had the lowest concentrations of P, K, Na, B, and Cu in the collected leachates. The higher level of P (i.e., 4% in Milorganite™ as compared to 2 and 0.5% in chicken and dairy manures, respectively, might have reduced the formation of Vesicular-Arbuscular (VA) mycorrhizae—a fungus with the ability to dissolve the soil P, resulting in slow release of P from Milorganite™ treatment than from the other two treatments. Patterns of nutrient dynamics varied with rain and irrigation events under the effects of the soil water and time lapse of the amendment applications’ rates and types. All the macronutrients were present within the rootzone and leached below the rootzone, except Na. The dynamic of nutrients was element-specific and was influenced by the amendments’ type and application rate

(R1491) Numerical Solution of the Time-space Fractional Diffusion Equation with Caputo Derivative in Time by a-polynomial Method
Get PDFIn this paper, a novel type of polynomial is defined which is equipped with an auxiliary parameter a. These polynomials are a combination of the Chebyshev polynomials of the second kind. The approximate solution of each equation is assumed as the sum of these polynomials and then, with the help of the collocation points, the unknown coefficients of each polynomial, as well as auxiliary parameter, is obtained optimally. Now, by placing the optimal value of a in polynomials, the polynomials are obtained without auxiliary parameter, which is the restarted step of the present method. The time discretization is performed on fractional partial differential equations by L1 method. In the following, the convergence theorem of the method is proved
(R1497) On the Invariant Subspaces of the Fractional Integral Operator
Get PDFIn operator theory, there is an important problem called the invariant subspace problem. This important problem of mathematics has been clear for more than half a century. However the solution seems to be nowhere in sight. With this motivation, we investigate the invariant subspaces of the fractional integral operator in the Banach space with certain conditions in this paper. Also by using the Duhamel product method, unicellularity of the fractional integral operator on some space is obtained and the description of the invariant subspaces is given
Miami-Dade County Status Offenders: A Literature Review of Punishment and Rehabilitation of Youth
Get PDFThe number of juveniles in detention centers has decreased across the United States. Although overall incarceration rates of juveniles in Miami-Dade County have declined, the number of youths at risk for delinquent activity and the number of girls in detention centers has increased. In the last nine years, Florida legislators have created laws to eliminate zero-tolerance policies in county schools, lessened the punishment role of law enforcement officers for in-school behaviors, as well as minimized the presence of law enforcement officers on school grounds. Although Miami-Dade County has been a part of the reformation of the Florida juvenile justice system, unlike Polk and Palm Beach County, it continues to enforce zero-tolerance policies. This is a comparable review of literature for the Miami-Dade County’s juvenile justice system’s treatment of status offenders
