Elementary Teachers' Planning for Mathematical Reasoning through Peer Learning Teams
Authors: Herbert Sandra , Bragg Leicha A.
Published: March 2023

Many elementary teachers find the complexity of understanding and teaching mathematical reasoning challenging. Teachers can benefit from professional learning (PL) programs designed to develop strategies to identify reasoning and implement it in mathematics lessons. This paper reports on a PL program designed to support a Peer Learning Team (PLT) of elementary teachers in Canada who were assisted by a researcher to peer-plan, peer-observe, and reflect on lessons fostering reasoning. Recorded data from PLT meetings were analysed against a planning framework to study the teachers’ growth in understanding reasoning. The findings revealed teachers engaged in a PLT which plans together to embed reasoning in a lesson, followed by peer observation and reflection is a powerful and effective model of PL for understanding mathematical reasoning and pedagogical approaches that foster students’ reasoning.

Sejarah perkembangan radar sudah ada diakhir tahun 1940-an, radar telah diintegrasikan ke dalam sistem pemanduan lalu lintas udara . Sejak itu telah banyak kemajuan yang dicapai baik peralatan maupun prosedur sehingga radar saat ini mempunyai kinerja jauh lebih baik dibandingkan yang dibayangkan semula beberapa tahun yang lampau. Peralatan radar saat ini telah dipasang di hampir seluruh unit pemandu lalu lintas udara di seluru dunia. Sistem radar sangat membantu tenaga pemandu lalu lintas udara yaitu menjaga keselamatan, kelancarandan keteraturan lalul intas udara. Keberadaan radar pertama kali adalah merupakan gagasan dari dua ilmuan Jerman yaitu Heinrich dan Christian Hulsmeyer, pada tahun 1922. Percobaan dlakukan oleh kedua ilmuan tersebut dan selanjutnya mereka dapat mempraktekandi lapangan. Mereka gunakan untuk menghindarkan tabrakan antar kapal laut di lautan. Dari situlah akhirnya membawa arah perkembangan radar. Sistem radar pertamakali digunakan pada tahun 1925 oleh Gregory Briet dan Merle A. Tune dari Amerika.

Electricity plays a big part in our daily life. Energy supply is a key factor in the modernization, automation, and expansion of the economy. Traditionally used energy sources are primarily used to create it. While traditional energy sourcesare rapidly running out, energy demand is rapidly increasing. A global problem is poor energy management as a result of scarce land resources, tight energy budgets, and weather-dependent renewable energy sources. Researchers that study energy are primarily concerned withthe depletion of conventional energy and the parallel development of practical alternative energy sources. Only 20% of the country's energy is used by homes; the remaining 80% is split across different economic sectors. When it comes to achieving sustainability in power generationfor sustainable development, the topic of renewable energy sources for generation cannot be overemphasized.The two main issues in the fight against climate change are without a doubt energy security and sustainability. Clean energy and a healthy environment are necessary for a world where people, plants, and animals can live in peace and health. Therefore, finding ways to incorporate renewable energy into the mix of energy production is necessary to improve energy sustainability and combat climate change. Todemonstrate their current condition and potential in the future, the literature on new energy sources is explored in this article. This analysis explains policies for renewable energy, potential assessments, comparative studies, energy optimization, sustainability, and the adaptation of strategic policies to promote the development of emerging renewable energy as a source of power generation to accelerate economic growth and preserve the environment.
Fishers’ lives matter: social issues in small-scale fisheries migration of Ghana
Authors: Asiedu Berchie , Failler Pierre , Amponsah Samuel K. K. , Okpei Paulina
Published: March 2023

Migration is a common feature of most small-scale fisheries (SSF) across the globe. To enhance fisheries resources sustainability and management, we examined the social issues in the SSF from the perspective of fishers, Chief Fishermen, and Fisheries Technical Officers who are actively involved in SSF migration and fisheries management along the coast of Ghana. We conducted in-depth interviews in six important migrant fishers’ communities and analysed documents on the socio-economic conditions of migrant fishers, conflicts among migrant fishers, rights of migrant fishers and the role of government in managing fishers’ migration. Findings showed that the successful integration of migrant fishers in the host communities resulted in minimal conflictual incidents that are resolved through dialogue. Furthermore, both the Fisheries Technical Officers and Chief Fishermen are involved in conflict resolution depending on the nature of the dispute. Also, most migrant fishers (over 50%) have the same rights as the local fishers, though they are marginalized during the distribution of premix fuel. Migrant fishers with prominent status played key role during decision-making process in the host communities. Overall, the study showed that migrant fishers have aided in the progress of fishing technology, food security, and small-scale business in the host fishing communities. To avert any form of marginalization during the distribution of premix fuel, it is prudent for authorities to develop relevant policies that will ensure that migrant fishers receive enough fuel for their fishing activities in the host communities.
A sequência didática “quem sou”, “onde estou” e “como estou” (os cinco sentidos) no projeto de extensão BioLibras/UFV a partir do olhar da pedagogia surda
Authors:   , Silva Wilson Fernando Pereira da
Published: March 2023

Este trabalho resulta de uma pesquisa participante que buscou respeitar os princípios da escolha de uma realidade concreta e dos participantes individuais e coletivos do processo formativo, de modo a contextualizar a investigação em sua dimensão histórica. Assim, partiu-se da perspectiva Freireana e da Pedagogia Surda, tendo como campo de estudo o Projeto de Extensão BioLibras, vinculado à Universidade Federal de Viçosa e que atua com estudantes Surdos de Viçosa e região. Dessa forma, analisou-se a sequência didática “QUEM SOU”, “ONDE ESTOU” E “COMO ESTOU”, abordando os cinco sentidos. Ela foi desenvolvida em 2018 com base nos pressupostos da educação em Ciências voltada aos/as Surdos/as. Para tal, iniciamos por uma pesquisa documental, em que foram recuperados os materiais das oficinas desenvolvidas na sequência didática, sendo feita uma linha do tempo e uma planilha descritiva. A partir disso, sistematizou-se, junto aos/às integrantes deste Projeto de Extensão, algumas das percepções relativas ao processo de construção da sequência didática. Por meio do grupo focal foram ativadas as memórias e a reflexão crítica sobre a prática educativa instituída. Após a sistematização deste trabalho, analisou-se os dados obtidos à luz da pedagogia Surda e das categorias propostas com base na literatura. Os resultados desse estudo indicaram que a elaboração e o desenvolvimento desta sequência didática colocaram o professor Surdo e os/as componentes do Projeto BioLibras como educadores/as populares, uma vez que desempenharam papel de articuladores/as, organizadores/as, incentivadores/as e mediadores/as do processo educativo. Ao mesmo tempo, colocou os/as estudantes Surdos/as na centralidade do processo de ensino e aprendizagem, em constante questionamento da sua condição na sociedade, como integrantes de uma população de minoria linguística. Também se verificou a proximidade da sequência didática com os princípios identificados na Pedagogia Surda, a partir do referencial teórico em questão. Nesse sentido, destacou-se a importância do ensino da Libras tanto para os/as alunos/as Surdos/as, quanto para as famílias e a sociedade em geral, favorecendo assim o empoderamento Surdo por meio da possibilidade de circulação da língua em diferentes espaços. Evidenciou também que o Projeto BioLibras, embasado na proposta de ensino bilíngue e tendo destaque o protagonismo de um professor Surdo, trouxe luz a escuridão de anos com um ensino oralista e opressor aos/as Surdos/as, sem o devido respeito às especificidades desse grupo linguístico e cultural. Assim, acredita-se que os resultados desta pesquisa poderão iluminar caminhos para uma educação bilíngue, para formação de professores/as e para novas formas de pesquisar e compreender as atuais demandas para a educação de Surdos/as. Palavras-chave: Educação de Surdos. Sequência didática. Pedagogia Surda. Ensino de Ciências.

Dişli Kayış Tahrikli Elektromekanik ve Pnömatik Uzun Stroklu Eyleyicilerin Maliyet Analizi İncelemesi
Authors: ERZAN TOPÇU Elif , İNCİ Mehmet
Published: March 2023

Otomasyon çalışmalarında pnömatik sistemler yaygın olarak kullanılmakla birlikte günümüzde elektromekanik tahrikli sistemlerin kullanımının yaygınlaşmaya başladığı gözlemlenmektedir. Elektromekanik sistemlerin pek çok farklı çeşidi bulunmaktadır. Genellikle servo motorun kontrol edilmesi ile hareket aktarımı sağlanmakta, bilyalı vidalı mil, dişli kayış vb. sistem elemanları ile dönme hareketi doğrusal harekete çevrilmektedir. Kontrol edilebilirliklerinin kolay, konumlama hassasiyetlerinin yüksek olması, uzun yıllar boyunca bakım istememesi gibi avantajlarıyla beraber bu tip sistemlerin kullanıcı tarafından tercih edilmesindeki en büyük tereddüt ilk yatırım maliyetlerinin yüksek olması olarak görünmektedir. Ancak ürün seçiminde ilk yatırım maliyeti ön plana çıkarken enerji tüketimi, bakım gibi parametrelerin de değerlendirilmesinin gerekliliği genellikle ikinci planda kalmaktadır. Bu çalışmada uzun stroklu, milsiz silindirli pnömatik bir sistem ile dişli kayış tahrikli elektromekanik bir sistemin ilk yatırım, bakım ve kullanım ömrü boyunca öngörülen enerji tüketim maliyetleri farklı çalışma senaryoları ile incelenmiş ve karşılaştırmalı olarak değerlendirilmiştir. Yatay yönde hareket eden iki sistemde de eşdeğer yük, strok, yıllık çalışma süresi ve kullanım zamanı dikkate alınarak deneysel çalışmalar ve teorik hesaplamalar yapılarak değerlendirilmiştir. Servo motorun ilk yatırım maliyetinin, pnömatik sistemin besleme basıncının, çevrim sayısının, bekleme süresinin sistemlerin maliyetlendirilmesinde önemli ve dikkate alınması gereken kriterler olduğu görülmüştür.

Abundance of fin (Balaenoptera physalus) and sei whales (B. borealis) amid oil exploration and development off northwest Scotland
Authors: Macleod K. , Simmonds M. P. , Murray E.
Published: March 2023

A ship-based line transect survey was conducted during July-August 1998 to assess the distribution and abundance of cetaceans off northwest Scotland. Limited information from dedicated surveys exists for this area and the lack of baseline data is cause for concern given the expanding oil industry in these waters. Historical whaling records show that large numbers of baleen whales, particularly fin and sei whales, were captured in these waters during summer. The waters surveyed included former whaling grounds and currently licensed oil blocks to the west of the Outer Hebrides and the Faroe-Shetland Channel and both fin and sei whales were encountered. Neither species was recorded to the west of the Outer Hebrides whereas relatively high densities of both were recorded further north in the Faroe-Shetland Channel. The density of fin and sei whales was 0.021km–2 and 0.022km–2, respectively. Abundance was estimated as 933 (CV=0.38) fin whales, 1,011 (CV=0.35) sei whales and 1,923 (CV=0.33) ‘large whales’. The high density of whales recorded in the Faroe-Shetland Channel supports the idea that it is an important summer feeding ground for both species and the potential for acoustic disturbance associated with increasing industrialisation of this area is a concern. Factors affecting the distribution and abundance of these whales are discussed.
A note on the movement of a humpback whale from Abrolhos Bank, Brazil to South Georgia
Authors: Stevick Peter T. , De Godoy Luiza Pacheco , McOsker Megan , Engel Marcia H. , Allen Judith
Published: March 2023

Most models of population structure for Southern Hemisphere humpback whales (Megaptera novaeangliae) assume that individuals feeding in the Scotia Sea migrate primarily to breeding and calving areas off Brazil. However data to support this are few and mostly indirect. Abrolhos Bank, Brazil, is the largest breeding and calving ground for humpback whales in the western South Atlantic Ocean. Historically, the waters near South Georgia held the largest concentrations of humpback whales in Antarctic Area II and were among the largest in the Southern Ocean. Photographs of individually distinctive natural markings on humpback whale flukes collected from the Scotia Sea (n=9) were compared with two collections of photographs from Brazilian waters (n=829 and n=735) to identify re-sightings. A humpback whale photographed in August 2000 at Abrolhos Bank was subsequently photographed in December 2004 near Shag Rocks off South Georgia. The migratory distance between these sightings is 3,945km. This finding constitutes the first long-distance individual resighting to be documented from either of these areas.
The Balance Of Legal Position Of Farmers With Dairy- Producing Industries In The Contents Of Milk Deposit Contracts At KUD
Authors: Widaningsih Widaningsih , Suhariningsih Suhariningsih , Sihabuddin Sihabuddin , Santoso Budi
Published: March 2023

The development of contract law gave birth to the principle of balance which states that a contract is binding as long as it is based on a balance of interests between the parties. The agreement is based on the terms of the validity of the agreement. The types of research are normative law, statutory approach and case approach. In conclusion, the contents of the contract on milk deposit at the KUD contain an agreement between the farmer and the milk-producing industry. In making a contract, the parties should have a balanced position, if they do not have a balanced position, it is possible that one party will dominate the other party. In the farmer's contract with the milk-producing industry, at the beginning of the contract (pre-contract) it appears that the bargaining position of the parties is balanced. If we look closely at the contents of the contract, there is an imbalance of position. The principle of balance has not been implemented properly, but the application of the principle of balance is indirectly contained in Article 1320 of the Civil Code, namely agreements, implementation in good faith and binding agreements with propriety, custom and law. Shows that in an agreement there should be a balance between the parties so as to create a sense of justice. An unbalanced contract has no binding force because it is contrary to good faith, a sense of justice, and propriety. As a result, an unbalanced agreement can be requested to cancel the agreement.
Re-imaging and re-conceptualize Hyper Terrorism in Indonesia: based on the Baudrillard framework
Authors: Sabar Alexander , Mustofa Muhammad , Meliala Adrianus Eliasta
Published: March 2023

Hyper-Terrorism in Indonesia has a strong relationship with the phenomenon of cyber terrorism. One of the primary uses of the internet by terrorist groups is to spread propaganda. Propaganda is a utility of hyperspace that is very useful for terror groups, especially in Indonesia. Propaganda carried out by terrorists is generally multimedia communication in the form of instructions, practical and ideological explanations, and justification or promotion of terrorist activities. These can take the form of virtual messages, presentations, electronic magazines, fatwas of ulama-supporting terrorists, audio-video files, and video games, all developed by terrorist organizations and their sympathizers. The terrorist group uses the internet for funding, training, and propaganda (including recruitment, radicalization, and incitement). In Jeans Baudrillard's concept, communication technology has given birth to a world of media that exists in parallel with reality, breaking the traditional linguistic relationship of sign and meaning, which he calls simulacra with hyperreality as the main characteristic. The big problem now is that there is no in-depth study on the definition of Hyper-Terrorism or the parameters in categorizing information as hyper-terrorism as a feature of the 'Simulacrum of Terror.' Examining the stages in the simulacrum of terror by Baudrillard, there is a missing stage between the results of media reproduction and the phenomenon of the simulacrum of terror. This research will take up the gap that Baudrillard missed. Then it becomes crucial to study academically, especially regarding the phenomenon of Hyper-Terrorism itself, namely hyperreality in terrorism propaganda, where the reproduction of information that is published globally brings up a relative representation.

The problem studied in this study is the fulfillment of the needs for weapons and ammunition for the TNI AD at PT Pindad, the purpose of writing this article is to find out what weapons and ammunition products are capable of being produced and the level of productivity in producing these products to support the needs of the TNI AD. Indonesia's participation, especially the TNI AD, in the ASEAN Armies Rifle Meet (AARM) competition which was held from 1991 to 2019 has recorded Indonesia as Champion 13 times. This can be interpreted that Indonesia is trying to maintain its championship position of 46.43% of the total championships that are participated in, in this case it is clear that PT Pindad's domestic products are able to compete internationally. The direction of PT PINDAD's policy in fulfilling the need for weapons and ammunition, especially for the Indonesian Army, is carried out on the basis of the concept of capability-based defense by considering possible threats to be faced and trends in the development of the strategic environment, its implementation is directed towards achieving Minimum Essential Force (MEF) strength. This research was conducted using a qualitative approach. Data were obtained through practical interviews with several sources. In addition, secondary data was obtained from search results from books, journals, official documents, official websites and other reliable sources. The result of the research is to find out the policies implemented by PT Pindad in meeting the needs of the TNI AD weapons and ammunition, especially if it is supported by policies and commitments that are in line with the TNI to meet the needs of the TNI AD weapons and ammunition.

Authors: Wei Yuanyuan , Wan Xia
Published: March 2023

In the research process, the methods of literature, interview, Delphi, questionnaire and mathematical statistics were used.From the perspective of push and pull theory, this paper studies the countermeasures to improve students' satisfaction in yoga courses.The satisfaction of yoga courses in Shenyang's colleges and universities is at the middle level, among which the satisfaction of "yoga teaching ability" and "classmate relationship" is relatively high; The satisfaction of "yoga teaching content and teaching method" and "course assessment" is relatively low. On the whole, the satisfaction of yoga teaching has great room for improvement.Through factor analysis and regression analysis, it is concluded that the thrust factor can be expressed by six indicators: improving physical fitness, improving body shape, optimizing interpersonal relationships, hobbies, challenging oneself, and achievements, of which improving physical fitness has the greatest impact; The pull factor can be expressed by six indicators: teacher's own factor, teaching content, teaching method, teaching assessment, teaching effect and teaching environment, of which the teacher's own factor has the greatest impact.Push and pull theory can be used to improve the satisfaction of yoga courses in colleges and universities. In terms of thrust, awaken the thrust factor and improve the satisfaction of yoga courses with the help of internal impetus; In terms of tension, optimize the tension factors and improve the satisfaction of yoga courses with the help of external tension.

Finding one's meaning and purpose in life depends on one's spiritual well-being. This is connected to resilience, which is a dynamic attribute of overcoming difficult conditions and a growth mindset. Thus, this descriptive, comparative, and correlational study wanted to know the degree of spiritual well-being and the level of resilience of emerging adults of a Catholic college in Central Negros. Spiritual Well-Being Scale and Resilience Scale standardized questionnaires were used among the 237 respondents. The results show that the emerging adults' degree of spiritual well-being is moderate, indicating that they have a fair sense of purpose in life. Likewise, the level of resilience yielded a moderate result. Further, results show a significant relationship between spiritual well-being and resilience. The findings typically indicate that emerging adults have a moderate sense of life's pleasure and purpose as well as the ability to bounce back from difficult situations. The results show that they have clung to God somewhat, but not entirely, and that their sense of purpose and direction in life are still unclear. They are still halfway to reaching their full potential and defining a clear life purpose. The study recommends the creation of a counseling program for the development of emerging adults.

Disentanglement of Latent Factors of Radiographic Knee Images for Knee Osteoarthritis Severity Classification
Authors: Ko Seung-woo
Published: March 2023

Knee osteoarthritis is the most common form of the musculoskeletal disorder that usually happens to the elderly. The diagnosis and treatment for knee osteoarthritis are causing a huge economic burden to society. Traditionally, the diagnosis for knee osteoarthritis was done by analyzing MRI (Magnetic Resonance Imaging). However, this method has problems in the way that it is costly and has limited access since they are only available in specialized medical institutions. There have been many researches that attempt to use x-ray images that are safe, cost-efficient, and commonly available. Their method often fails and shows poor results due to a lack of training dataset. In this paper, I proposed a novel autoencoder-based knee osteoarthritis classification system. Unlike the previous deep learning-based research, the proposed method disentangles the osteoarthritis-related latent factors from knee x-ray images. These latent factors are then trained to predict the severity of osteoarthritis. The proposed method achieves accuracy of 78.9% on the publicly available dataset. Our method produces accurate results without having a large dataset while successfully avoiding the curse of dimensionality. Throughout the comprehensive experiment, I have shown that the proposed method outperforms the existing state-of-the-art methods by a great accuracy margin.
Gender in US Politics
Authors: Li Hantong
Published: March 2023

This paper discusses the impact of gender stereotypes on American female politicians. To demonstrate this problem, the paper will start by examining the struggles that female politicians face in their political careers because of their gender, focusing on their campaign strategies, political image, etc. This paper will then use the political life of Democratic candidate Hillary Clinton as a more specific example of the impact of gender bias. The “double bind” that Clinton has faced as a woman and a politician has negatively impacted her political campaigns. Gender stereotypes have also conditioned the media and the public’s response to her. Through focusing on the “evolutions” of Clinton’s political strategies throughout her career, this paper argues that Hillary Clinton has always grappled with gender stereotypes. However, even when she addressed criticisms that she faced in the past, she stilled failed to meet voters’ demands.
The Effects of Nutrients on the Efficiency of Motor Oil Bioremediation by Pseudomonas putida
Authors: Elliott Bethany , Fox Sara
Published: March 2023

Bioremediation is an innovative solution to reduce harmful chemicals in the environment using microorganisms and plants, making pollution removal more eco-friendly and cost effective. Nutrients are often applied to enhance the process of bioremediation, allowing for larger, more active colonies of bacteria to grow and consume contaminants. The purpose of this project was to study the limits and effects of adding various amounts of nitrogen, phosphorus, and potassium to the environment of Pseudomonas putida as it consumed hydrocarbons in motor oil. In the experiment, test tubes of water, motor oil, bacteria, and varying amounts of nutrients were observed for two days. At the end of the two day period, the amount of oil left in the tubes was analyzed using a spectrophotometer to calculate the turbidity as absorbance numbers. It was found that there was a distinct negative trend in absorbance with each increase in nutrients, signifying that the nutrients allowed for greater growth and hydrocarbon consumption by Pseudomonas putida. However, there was not an observable limit to the benefits of adding nutrients. This is likely due to Pseudomonas putida’s strong chemotaxis towards hydrocarbons, and not towards other nutrients. Additionally, it was discovered that increasing the potassium promoted more oil consumption, due to potassium’s key role for cellular transportation and moderation of turgor pressure. The results of this experiment can be used to guide which nutrients to prioritize in the bioremediation process, but more research must be done to discover the full extent of adding nutrients to a realistic environment.
