Authors: ÜNAL AÇIKGÖZ Merve
Published: December 2021

Başkanlık sisteminin prototipi olarak kabul edilen Amerika’da başkanın seçilme usulü diğer ülke uygulamalardan farklı bir şekilde gerçekleştirilmektedir. İki aşamada gerçekleştirilen seçimde halk, başkanı doğrudan seçmek yerine başkanı seçecek olan delegeleri seçmektedir. Demokratik sistemlerde iktidarlar, meşruiyet kaynaklarını özgür ve serbest seçimlerden almaktadır. Bu nedenle seçimlerde uygulanan sistemin, parti yapılarının, oy kullanma şartlarının ve seçimlerin yönetiminin ideal demokrasi ilkelerine uygun olarak düzenlenmesi gerekir. Dolayısıyla seçime ilişkin demokratik ilkelerin hukuksal kurallar aracılığıyla koruma altına alınması önem arz etmektedir. Amerika’daki başkanlık seçiminin temel bileşenlerini seçim sistemi, siyasi partiler, oy hakkının kullanılması, seçim kampanyalarının yürütülmesi ve seçimlerin yönetimi ve denetimi ile yetkili makamlar oluşturmaktadır. Bu çalışmada, Amerikan başkanlık seçiminin işleyişi, seçim kuralları, seçimi etkileyen mekanizmalar ve Federal Yüksek Mahkeme’nin seçim dönemlerinde üstlendiği görev ele alınmaktadır.
The Argonautic Expedition: The First Worldwide Naval Epic
Authors: Psimopoulos Angelos Per.
Published: December 2021

The Greek mythology is widely acclaimed as one of the richest treasures of universal epics; the myth of the Argonautic Expedition is one of the most interesting Greek myths. Some scientific authorities hold the opinion that the story of the Argonauts was no more than an inspiring fairy-tale, while others insist, it was a real historical event. They believe that it took place in 1225 BC, and Colchis was a country located in the Caucasus Mountains, near today’s country of Georgia. After a life-long study of more than thirty years using ancient texts and information coming from nautical maps and geography, oceanography and other fields of science, we propose that the real events were quite different from the currently proposed location. The Argonauts, and ancient Greeks at large, wanted to find a sea route to transport silk textiles and new species from the Far East countries to Greece or at least to open the Overland Route leading from the Black Sea to the Far East. In addition, they wanted to transport to Greece silkworm eggs to cultivate silkworms in Greece and produce silk. They started their journey from Iolcus and travelled around the Globe; they reached Colchis, Aeëtes' land that was actually China. They took from China eggs of the wild Silkworm instead of the real one and, sailing through the Indian Ocean, reached Suez, where they were forced to pull their ship across the land to reach Tritonis Lake. From there, they exited into the Mediterranean and arrived at Iolcus, the city from which they started their journey. That journey was made by the Argonauts around 1510 BC. Presently, giving a plethora of bibliographic references, we shall carefully attempt to expose the real events that happened during those ancient times under the mission code name "transporting the Golden Fleece to Greece". We shall say, who did this perilous feat, when and where it happened, what was the real purpose of the Argonauts’ journey, which were the correct routes followed carefully by the Argonauts, what were the countries they crossed or visited and finally what the Argonauts accomplished with that journey.
MATHEMATICAL MODEL OF UNDERWATER DEMINING BY DIPPER DIVERS OF THE SESU
Authors: Soloviev I.
Published: December 2021

It is shown that the problem of improving the effectiveness of prevention of emergencies related to the underwater location of explosive objects is relevant. An important and unresolved part of the problem is the lack of a mathematical model of the emergency response process associated with the underwater location of an explosive device in general. Based on this, the object of the study was the elimination of an emergency situation related to the underwater location of explosive objects, and the subject of the study – the process of operational activities of personnel of the underwater demining department of a group of special diving rescue team. The aim of the work is to develop a mathematical model of the emergency response process related to the underwater location of an explosive object as a process of functioning of the system "emergency – special means of underwater demining – diver-sapper", which should be the basis for substantiation of operational and technical recommendations. increasing the efficiency of underwater demining by diver sappers without reducing their level of safety.
It is shown that the mathematical model of underwater demining by a diver-sapper is a system of three analytical dependences. The first is a functional that describes the process of underwater demining in the form of a three-factor polynomial model. The second allows us to present this functionality as a set of one-factor models. The third provides the definition of weights in solving a multifactor problem. It is noted that such a model allows to proceed to the substantiation of operational and technical recommendations to the management of the group of special diving works.
The advantage of the new scientific result is the ability to obtain both quantitative estimates of the impact of the direct components of the system "diver-sapper – special means of underwater demining – underwater location of an explosive object" and their relationship. The disadvantage is the large number of experimental results that must be obtained to implement the selected plan.

History and Memory of Dissident Sexualities from Latin America
Authors: Bisso Schmidt Benito , Mascarenhas Neto Rubens
Published: December 2021

This article focuses on Red Latinoamericana de Archivos, Museos, Acervos y Investigadores LGBTQIA+ (AMAI LGBTQIA+), a network composed of researchers and institutions related to LGBTQIA+ memory in Latin America, founded in 2019. First, the authors analyse the network’s creation arising from the discontent of some participants of the June 2019 Archives, Libraries, Museums and Special Collections (ALMS) Conference, in Berlin, who felt bothered by the lack of attention given to subaltern perspectives on LGBTQIA+ history and memory. Next, the authors describe and analyse the network’s first year of activities communicated through its Facebook group. Multiple challenges arose from creating a network with members from different national origins, languages, and identities, especially considering the conservative political contexts of several Latin American countries and the social distancing measures imposed by the COVID-19 pandemic. Next, the authors present a general profile of the network’s members and a map of partner institutions. Finally, the article points out some challenges to the network’s continuity and its desire to render Latin America more visible in the broader panorama of global LGBTQIA+ history. The authors conclude by highlighting the importance of AMAI LGBTQIA+ in stimulating further discussions about the participation of global-south researchers and perspectives on global queer history initiatives.

Os desastres e a ambientalidade crítica do capitalismo
Authors: Henri Acselrad
Published: December 2021

O presente texto discute as possíveis articulações entre as noções de crise ambiental e de desastre, de um lado, e os processos de reprodução e crise do capitalismo, de outro. Assumindo uma perspectiva crítica com relação às concepções que reificam a tecnología e atribuem a crise ecológica ao poder destrutivo das técnicas, o trabalho desenvolve a hipótese de que os indicadores de desregulação climática e os desastres a eles associados resultam de uma determinada forma de coordenação das práticas espaciais, que tem por base a distribuição desigual dos riscos ambientais e tecnológicos.

Palavras-chave: Capitalismo. Desastres. Crise. Desregulação. Risco.
Nota Editorial

Published: December 2021

O Comitê Editorial da Revista Ciência & Trópico, periódico interdisciplinar com dimensões internacionais, cujo objetivo é contribuir para a divulgação de pesquisas atuais e consistentes nas áreas de Ciências Humanas e Ciências Sociais, sente-se mais uma vez honrado em poder dedicar este número à discussão sobre desnaturalização dos desastres em parceria com os profissionais da Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro.
A dimensão internacional da temática leva a compreender por que desnaturalizar a concepção dos desastres e fortalecer os movimentos comunitários é condição essencial para que novos regimes de produção do saber possam emergir, fortalecendo redes e resistências na criação de novos modos de atuar na vida, tornando as pessoas capazes de enfrentar desafios, indicados pelas mudanças climáticas e provocados pelo atual modelo de desenvolvimento.
Sempre coube à Fundação Joaquim Nabuco trabalhar em parceria com instituições de excelência que buscam conhecer a realidade para transformá-la e lançar desafios com esteios em novas convicções. Essa é a segunda oportunidade de aprofundar o debate com a Fundação Oswaldo Cruz sobre a desnaturalização dos desastres no cenário internacional, agravada pelos caminhos sombrios de uma pandemia. Ressalte-se, ainda, que tudo o que se acenou para uma futura crise gerada pelas mudanças climáticas já estava presente nos desastres socioambientais, os quais que se expressam não apenas em indicadores, mas no comprometimento absoluto da felicidade. É difícil reconhecer que nós mesmos, sociedade, governos, stakeholders do desenvolvimento, organizações internacionais, engendramos o comprometimento da justiça social expressa nas desigualdades sociais cada vez mais evidentes no rastro do flagelo da COVID-19. Temos que saber construir, como na xilogravura de J. Borges, a nossa Casa no Sítio, o lugar em que cabem as cores da reconstrução e da esperança.
Concluindo este número, além de cumprir uma missão institucional, ampliando horizontes temáticos, fortalecendo debates de todos os matizes e garantindo a liberdade de expressão de todos os que submetem seus artigos à apreciação dos inúmeros pareceristas que merecem nossos agradecimentos pelo trabalho sério que garante a continuidade e a renovação da Ciência & Trópico.
Na qualidade de Editora-chefe e pesquisadora da Fundaj, agradeço o trabalho do Editor assistente, Luis Henrique Lopes, dos editores convidados, Sérgio Portella e Simone Oliveira, da Fiocruz, da revisora da Fundação Joaquim Nabuco, Solange Carvalho, dos colegas da Iconografia, em nome de Albertina Malta, que está sempre pronta a promover o acervo artístico da Fundaj, da Editora Massangana e de todos que compartilham ideias, cores e a força do compromisso de seguir adiante.
OWNERSHIP AMONG SCIENCE TEACHERS
Authors: Janiuk Ryszard M.
Published: December 2021

Science education is continuously changing in terms of goals, curricula and teaching methods. Such changes stem from major educational reforms and the development of new theoretical concepts related to science teaching. It has been long emphasised that the implementation of these changes in schools depends on the teachers, who need to identify with and support the innovations which are to be introduced, and to feel that change is necessary. An active involvement of teachers in the process of designing, developing and implementing innovation is one of the indicators of a sense of "ownership", which in this case can be understood as identifying with the innovation, feeling as if one is its owner. This psychological state can be achieved thanks to teachers’ investment in the innovation, and has the potential to reduce resistance and create a better climate for change. Ownership can have a considerable impact on teachers' involvement in further changes, if they notice that innovation has a positive influence on the effects of their work. Ownership also has a beneficial impact on their working environment, motivating other teachers to implement the desired change and thus helping spread the change throughout the teacher community.

Authors: Šorgo Andrej , Usak Muhammet , Kubiatko Milan , Fančovičova Jana , Prokop Pavol , Puhek Miro , Skoda Jiri , Bahar Mehmet
Published: December 2021

The purpose of this study was to measure the freshmen’s level of knowledge about genetics, evolution, human evolution, the nature of science, and opinions on evolution and the presence of non-scientific explanations among Czech, Slovakian, Slovenian and Turkish students. Determination of prior knowledge and pre-conceptions about these issues is important because they are filters to learning other related concepts. The results are going to be a starting point for developing teaching strategies concerning Darwinian evolution and preparing prospective science teachers for working with students in national and international contexts. A total of 994 first-year university students from the Czech Republic (276; 27.8%), Slovakia (212, 21.3%), Slovenia (217, 27.3%) and Turkey (235, 23.6%) participated in this study. The findings can be summarized as follows: knowledge especially that of the nature of science at the freshmen level was seriously flawed. Non-scientific explanations were present in high percentages. Both were regarded as barriers towards scientific reasoning and acceptance of general human evolution especially for students expressing orthodox religious beliefs.
Key words: evolution, genetics, human evolution, nature of science, non-scientific explanations.

Authors: Yangin Selami , Sidekli Sabri , Gokbulut Yasin
Published: December 2021

This study reported herein aimed to reveal prospective teachers’ misconceptions about classification of plants and the effect of pre-service education program on their correct conceptions of this biological issue. Prospective teachers majoring in Elementary School Classroom Teacher Education constituted the target population of this study during the fall semester of the 2012-2013 academic years from Turkey. In order to reveal the difference between the misconceptions of prospective teachers who are at the beginning and at the end of their university education, the research was conducted as a cross-sectional study (78 first and 84 fourth class). The results showed that the prospective teachers in both groups have misconceptions and considerable confusion over the concepts of without-seed plants, seedy plants, vascular plants, non-vascular plants, gymnosperm plants, angiosperm plants, fruit and vegetable. In addition, the pre-service education did not seem to have an important effect on correction of prospective teachers’ misconceptions about classification of plants. In this context, prospective teachers are graduated with misconceptions about classification of plants. Key words: biology, classification of plants, misconceptions, prospective teachers.
PUPILS’ EARLY EXPLORATIONS OF THERMOIMAGING TO INTERPRET HEAT AND TEMPERATURE
Authors: Schönborn Konrad , Haglund Jesper , Xie Charles
Published: December 2021

In thermodynamics teaching, pupils have been found to confuse temperature and heat, and to conceive touch as an infallible thermometer. This study explored the potential of combining the sense of touch with infrared (IR) thermal imaging on pupils’ understanding of heat and temperature. Eight 7th-grade pupils (12-13 years old) worked in pairs across three laboratory exercises (real-time IR imaging, static IR images, or thermometers) to predict, observe and explain (POE) the temperatures of different objects. An anomaly between perceived ‘coldness’ and measured temperature was induced among the pupils, but they did not manage to resolve this cognitive conflict. The pupils observed the objects getting warmer and increasing in temperature, but did not explain the experiments as involving a heat flow from their bodies to the objects. Successful explanation might require a combination of thermal imaging and the explicit introduction of a simple heat-flow model.
Key words: cognitive conflict, heat, multisensory experience, predict-observe-explain (POE), temperature, thermal imaging.
UNDERSTANDINGS OF ADVANCED STUDENTS ON NATURE OF SCIENCE AND THEIR MOTIVATIONAL STATUS TO LEARN NATURE OF SCIENCE: A TURKISH CASE
Authors: Köksal Mustafa Serdar , Şahin Canan Tunç
Published: December 2021

In this study, the purpose is to describe advanced students’ motivational status to learn Nature of Science (NOS) and their understandings on NOS by using Ranking Questionnaire for “interest” and “importance” and modified version of Views on Nature of Science Questionnaire. The results indicated that the participants did not see NOS as an important subject compared to mathematics, science and social science subjects. Moreover, the participants were more interested in mathematics and science subjects than in NOS subject. The results on NOS understandings also showed that the participants were transitional in terms of “evidence and observation based science” and “subjectivity” while they had informed understandings on “place of imagination and creativity in science”. They were also naïve in terms of “existence of one method in science”, “no hierarchy between theory and law”, “tentativeness” and “difference between observation and inference”. The results explained an important motivational problem to implement any NOS teaching methods to change misunderstandings. Key words: advanced high school students, motivation, nature of science, school subjects.
