Get PDFThis study examined the perspectives of administrators and teachers on the effectiveness of the PBIS framework in Title I elementary schools. This paper reviews the history of the discipline in schools in America and how student behavior has evolved. It includes an overview of social-emotional programs and discusses the need to incorporate them into the school day. The focus was on the PBIS framework in a specific middle Georgia county. Results were obtained through the analysis of the PBIS Self-Assessment survey and semi-structured interviews. Overall, the findings discovered that there was no statistically significant difference in the perceptions of elementary administrators and teachers. The results found that both populations perceived the PBIS framework to be beneficial to school climate, student success, and reduced school violenc
Using the Community of Practice Framework to Examine Informal Science Educators\u27 Epistemological and Pedagogical Beliefs in Informal Science
Get PDFWhen ranked and compared to students in other countries, students in the United States of America consistently rank below their peers in science knowledge. Among the many recommendations for increasing the science knowledge of students is a merge of informal science education (ISE) and public and private science classrooms. There is limited research focused on (1) the historical trends of research conducted in informal science education including the methodologies employed and pedagogical practices revealed and (2) the epistemological and pedagogical beliefs of formal science educators, who hold dual positions in the classroom and in an informal science setting. This dissertation includes two studies which are written as articles: (1): the completion of a content analysis of 30 peer-reviewed journal articles from 2006-2021 and one book (Preparing Informal Educators) and (2): a qualitative exploratory case study using photo-elicitation, semi-structured interviews, and an open-ended questionnaire. The results from Article 1 (the content analysis) revealed that informal science educators are often not equipped to implement the needed hands-on active educational methods, creative experiences, and memorable experiences to reach young learners. Article II (a qualitative exploratory case study) examined the epistemological and pedagogical beliefs of 10 science educators working at a local science museum. This two-article dissertation revealed harmonized pedagogical and epistemological beliefs between formal science educators and informal science educators using CoPs
Synthesis, Characterization and Activity of Palladium Catalysts on the Dual Support of Cerium and Aluminum Oxides
Get PDFThe effects of sequence of impregnation (Pd on cerium oxides -alumina and cerium oxides on Pd-alumina) and calcination temperature (500 ℃ and 850 ℃) on the catalytic oxidation of methane under lean conditions were investigated. The catalysts were prepared by a combination of impregnation, slurry and vortexing methods. The catalysts had 4.7 wt.% Pd and 10.7 wt.% Ce based on inductively coupled plasma optical emission spectrometry (ICP-OES) analysis. The catalysts were characterized by pulse chemisorption, temperature programmed reduction (TPD), scanning transmission electron microscopy (STEM), and X-ray photoelectron spectroscopy (XPS). The activity of the catalysts for methane combustion was measured in a fixed-bed flow reactor by flowing a gas mix (0.98 vol % methane, 4.01 vol % and balance nitrogen) through a catalytic bed. The temperature of the catalytic bed was controlled by a temperature -controlled tube furnace. The % methane in the effluent gas mix was measured by a gas chromatograph fitted with a flame ionization detector and a ‘Carbon Plot’ column. Palladium was present as PdO and PdOx x\u3e2+ and cerium as CeOx (+3 and +4 oxidation states) as per XPS analysis. The activity of the Pd/cerium oxides-alumina500C catalyst was higher than the cerium oxides/Pd-alumina500C catalyst at 250-500 ℃. Similar trends in the activity were seen for the two catalysts calcined at 850 ℃. Higher dispersion and lower particle size, and the presence of small Pd particles on alumina accounted for the higher catalytic activities of the Pd/cerium oxides-alumina500C and 850C catalysts. The lower activities of cerium oxides/Pd-alumina500C and 850C were primarily due to the embedment of Pd onto ceria due to strong PdO-CeOx interactions. This research implies that the sequence of impregnation and calcination temperature could alter catalytic properties and activity for methane combustion through PdO/PdOx -support interactions
The Roots of Voodoo Run Deep in Haitian Soil
No full textIn the diplomatic, religious, and social isolation that followed the Haitian Revolution, Haitian elites privileged the models of freedom demonstrated by the United States and the French Republic and strove to be taken seriously in the eyes of their European and American contemporaries. The Haitian peasantry had more pressing concerns than the ideological foundation of freedom as they struggled with the practical aspects of emancipation. Free, but not free to return to their homelands. Free, but without meaningful political and social institutions to support their freedom. Free, but civically disengaged from state-level concerns, and all but ignored by the Haitian government, the peasantry developed grassroots concepts of freedom and nationhood. Their bottom-up approach was not a coordinated attempt at nation-building, nevertheless, between 1806 and 1847, organic nationhood fluoresced among Haitian peasants, rooted in the physical and metaphysical spaces of the emergent Vodou religion
Role of Reflection in Education
No full textThere is no disagreement about the role of reflection in education. The Educational Policy and Accreditation Standards of the Council on Social Work Education (2015) purports a holistic view of competence, that includes the social worker\u27s critical thinking, affective reactions, and exercise of judgment in regard to unique practice situations (CSWE, 2015). We propose Autoethnography as a meta assignment that will help measures Cognitive and Affective reasoning. This Poster describes the process of linking espoused theory to theories in action and arriving at a personal practice philosophy. This philosophy is anchored in the narration of Autoethnography which is personal and unique to each student. Students retroactively and selectively write about past experiences and describe their trajectory of events in social work education that prepared or stifled their preparation for practice in social work. Students write their own Autoethnography and describe their own life experiences that motivated them to seek social work as their profession of choice (espoused theory). Students note significant events that generated excitement, concern and/or unresolved issues (theories in action). Students also consider their practicum and describe how it challenged their preconceived notions, world views, and assumptions. Students describe how they responded to the shifts experienced in status-quo, and arrive at a resolution that made them comfortable with clients and with social work practice itself (personal practice philosophy). As part of Autoethnography, each student plays the role of a narrative inquirer, and their peers play the role of responders. The Narrative Inquirer narrates the incident, context, and social work practice along with value assumptions. Students as responders in Narrative Inquiry appreciate a point of view that is different from their own, articulate their own perspective, provide appropriate feedback and actively pursue collaboration and co-production process that helps reframe personal practice philosophy
Leadership in the Digital Exponential 21st Century
No full textThis presentation will discuss ten 21st Century technologies that will have direct impacts on higher education. The twenty-first century will experience a number of technologies that will significantly modify how faculty teach, what students learn, and how leadership is conducted in education from secondary school to the university. The ten technologies that need to be considered are Autonomous Vehicles (cars, trucks, and drones), 3D Printing - also known as Additive Manufacturing, the Internet of Things, Personal Robots, Medical Genome Development, Agricultural Genome Development, and the three big elephants in the room, Quantum Computing, Artificial Intelligence, and Nanotechnology. Each of the above cited technologies do not develop like 20th-century inventions such as the automobile or the airplane. Those and many more developed in a linear manner, over a lengthy period of time. The Wright Brothers\u27 aircraft to the Boeing 777 took over half a century. The Ford Model T to the Mustang took over fifty years to develop. The improvement of these inventions was relatively easy to observe and predict. To get an idea of how 21st-century inventions develop, consider Uber and Airbnb. In a matter of four to five years, they start as an idea and become national and then international phenomena. They develop in a two-stage manner: Stage 1 - Linear and Stage 2 - Exponential. Each of the ten technologies listed above will develop in the same two-stage manner because they are supported by the computer and the internet. The presentation will focus on how leaders in higher education can deal with the impending, exponential changes. The business leaders already understand that in order to stay in business in a globally competitive world they will have to adapt to the rapid changes the ten technologies will create. Educators, if unprepared, stand to be swept up in a series of disruptions they will not fully comprehend. Preparing for a disruptive, exponential future is critical for future educational leaders and faculty to understand. This presentation will discuss the exponential situation and provide a leadership pathway to success in higher education administration, teaching and learning
The Role of Security, Privacy, and Trust in IoT Acceptance and Use
No full textInternet of Things (IoT) is emerging as a novel paradigm where a global set of everyday objects can be equipped with identifying, sensing, networking, and processing capabilities in data communication. Despite its popularity and potential benefits, there are rising concerns about paralleling pervasive security and privacy with its pervasive computing. Much effort has been devoted to IoT framework development and technological advances, whereas individuals\u27 attitudes and behaviors toward security and privacy while adopting IoTs have been rarely examined in the prior literature. In addition to their significant participation in the consumption and use of IoT applications such as wearables and smart home systems, we argue the importance of individual security and privacy in its extension in healthcare - Internet of Bodies - those devices connected to or sometimes inside the human bodies. To address this research deficiency, we aim to explicate the user acceptance of IoTs in the context of security and privacy. In the lens of rational choice theory, cost-benefit analysis, and technology acceptance model, this study attempts to expand the security landscape from conventional perception, transportation, and application layers to the user layer. In this study, we start with a survey of security and privacy issues related to IoTs while delineating the critical human factors across the IoT platform and functional layers. Given the coexisting benefits and costs, we will shed light on individual cognitive processes and intentions in adopting and using IoTs while dealing with security and privacy concerns. Also, we propose a conceptual model based on our theoretical development. Lastly, we provide directions for future research, including research methodology, data collection as well as practical implications
SIR Model and the Data Fitting of Covid-19 in South and Southeast Asia
No full textBy February 2021, the overall impact of the coronavirus disease 2019 (COVID-19) in South and Southeast Asia had been relatively mild. Surprisingly, the second wave in early April 2021 in this region becomes devastating and attracted worldwide attention. Methods We focus on the nine countries with the highest accumulative deaths due to the disease by July 30, 2021. We study the transmission dynamics of the COVID-19 in South and Southeast Asia using the reported death data and fit into a mathematical model with a time-varying transmission rate. Results We estimated the transmission rate, the infection fatality rate, and the infection attack rate, the effects of vaccination in the nine countries in South and Southeast Asia. Our study suggests that the infection attack rate is still low in most countries and vaccination is needed to prevent further waves. Conclusion The implementation of the non-pharmacological interventions (NPIs) could have helped South and Southeast Asia to keep the COVID-19 under control in 2020 as reflected in our estimated low transmission rate. Factors like the emergence of the new Delta variant, social unrest, and migrant workers could have been the trigger of the second wave of COVID-19.

Serving our Children During and After COVID-19: Application of Shepherd Leadership at Home and School
Get PDFShepherding is one of humanity’s oldest known occupations, dating back thousands of years (Leman & Pentak, 2004). Yet, within the way of a shepherd lies hidden leadership treasures, which are especially valuable for parents, caregivers, and teachers during and after COVID-19. Shepherd leadership is a specific form of servant leadership. Although there are many similarities between shepherd leadership and servant leadership, theoretical or empirical studies of shepherd leadership are far behind servant leadership. The most referenced texts of shepherds and shepherd leadership can be found in the Bible. This paper examines the thinking, doing, and being of shepherds and the practical applications—guiding, providing, and protecting—of shepherd leadership to modern-day living. Multiple analyses of the Davidic Psalm 23 provide examples and illustrations of shepherd leadership principles. The current global pandemic is causing psychological, emotional, mental, and social effects on children (Ghosh et al., 2020; Ritz et al., 2020; United Nations, 2020). When country leaders and governments work hard to provide medical care for patients and vaccines for citizens, those who are parents, caregivers, and teachers can shepherd their children through the valley of the shadow of death and arrive at the tableland for enjoyment and pleasure. It is argued that shepherd leadership can be adopted by parents, caregivers, and teachers who serve the needs of children during and after COVID-19
