QHDOPT: A Software for Nonlinear Optimization with Quantum Hamiltonian Descent
Authors: Kushnir Samuel , Leng Jiaqi , Peng Yuxiang , Fan Lei , Wu Xiaodi
Published: November 2024

We develop an open-source, end-to-end software (named QHDOPT), which can solve nonlinear optimization problems using the quantum Hamiltonian descent (QHD) algorithm. QHDOPT offers an accessible interface and automatically maps tasks to various supported quantum backends (i.e., quantum hardware machines). These features enable users, even those without prior knowledge or experience in quantum computing, to utilize the power of existing quantum devices for nonlinear and nonconvex optimization tasks. In its intermediate compilation layer, QHDOPT employs SimuQ, an efficient interface for Hamiltonian-oriented programming, to facilitate multiple algorithmic specifications and ensure compatible cross-hardware deployment. The detailed documentation of QHDOPT is available at https://github.com/jiaqileng/QHDOPT .

Developing sociolinguistic context-based English-speaking materials for Islamic senior high school students
Authors: Susilawati Endang
Published: November 2024

This research was conducted for two purposes: (1) to describe the process of the design and development of English materials for conversation practices based on the sociolinguistic contexts for Grade X students at Islamic Senior High School Students (ISHS), and (2) to analyze the usability level of the product of materials’ development for the students. It is a study using research and development method which applied the stages of ADD out of ADDIE from Aldoobie, (2015) and Branch, R. M. (2009). The materials development focused on English-speaking materials in the form of conversation practices, which included the conversations of interpersonal and transactional communication whereby the sociolinguistic contexts are embedded. Additionally, communicative tasks were also presented for engaging students with the practice of the real English use. They were packed in the form a textbook which consisted of six units. The presentation of the materials in the units was following the features of CLT approach. The feasibility and the usability of the product was tested through internal validation using the three criteria (psychological, pedagogical, and content) of validity by Rubdy (2014). The result shows that the English-speaking materials are valid meaning usable for Grade X students of ISHS.
Investigation into students’ performance in foreign language business writing and their attitudes toward it
Authors: Thaksanan Piriya
Published: November 2024

Anxiety can affect learners' performance in several ways. It can be a helpful motivational tool to assist students in learning a language. At the same time, anxiety can become a serious factor in hindering language acquisition. This study examines the relationship between students' writing performance and anxiety levels across three different proficiency groups of students. The participants were fifty EFL students enrolled in a Business English Writing course, and the target writing genre was inquiries and acknowledgments of inquiry letters. The two main instruments used to collect data were students' writing samples and closed-ended questionnaires. The data were analyzed utilizing descriptive statistics, one-way ANOVA, and Pearson's coefficient correlation. This study showed a significant difference in writing anxiety between the high and the low-proficiency groups. In contrast, it was found that there were no statistically significant differences in anxiety between the high and the mid-proficiency groups. In addition, the study’s outcomes indicated that the students' level of anxiety varied across the three groups of students. It was found that the students with a high level of anxiety performed less well than those with lower writing anxiety. The findings provide insights into teaching and learning writing, particularly into ways to decrease learners' anxiety and improve their learning outcomes.

Authors: Radjaban Yohanes , Humanika Eko Setyo
Published: November 2024

Problems in developing writing often comes from creative processes in developing ideas to write. Outlines are often recommended as a tool to help students organize their thoughts and structure their writing. This study aims to find out students’ perceptions and the challenges the students encountered when writing an exposition text using provided outlines among the students of English Department of UTY. This study used mixed method approaches. Questionnaires and semi-structured interviews were applied to collect data. Respondents of this study were 20 students (10 males and 10 females) from second year students of English Literature Department of Yogyakarta University of Technology academic year 2023-2024, and through a purposive random sampling technique. A questionnaire was used to figure out students' perceptions, and semi-structured interviews were conducted to find out the challenges encountered by students when writing an exposition text using provided outlines. Nine respondents (6 females and 3 male) were selected in the interview session based on their scores, they were four students with the highest scores, three students with middle scores, and two students with low scores to be interviewed. The semi-structured interview data were analyzed qualitatively using the interactive model. The results of this study show that most students agreed that outlines help them write exposition texts, with 80% agreeing or strongly agreeing with the statement “The outline helps me write an exposition text.” However, students also reported three challenges, difficulty in developing connections between theory and research topics, with 60% indicating they found this aspect challenging, 55% found it challenging to translate their outlines into coherent exposition texts, and 30% students indicated a lack of confidence in their ability to use outlines effectively. This learning model may help students participate, engage, and enhance their confidence in writing exposition texts, and lecturers are aware of the importance of targeted instructional strategies, such as providing more examples and practice opportunities for developing connections between theory and research topics.

EU-TU E EU-ISSO DE MARTIN BUBER: REPRESENTAÇÕES SOCIAIS DE PROFESSORAS SOBRE ESCOLARIZAÇÃO DE SURDOS
Authors: Lobato Huber Kline Guedes
Published: November 2024

Este artigo focaliza os pressupostos teóricos e metodológicos sobre a Teoria das Representações Sociais e os princípios filosóficos de Martin Buber acerca das atitudes Eu-Tu e Eu-Isso. O estudo surgiu do seguinte questionamento: que Representações Sociais são partilhadas por professoras sobre as atitudes estabelecidas com alunos Surdos no contexto escolar de Breves-Pará? Assim, temos como objetivo neste estudo analisar as Representações Sociais de professoras acerca das atitudes estabelecidas com alunos Surdos em Breves - Pará. A pesquisa se fundamentou em uma abordagem qualitativa, se caracterizando em uma pesquisa de campo e estudo de caso, sendo que foi desenvolvida com base na metodologia de pesquisa das Representações Sociais. Os procedimentos metodológicos elencados foram a observação no lócus e as entrevistas individuais com 05 (cinco) professoras de Breves-Pará. Para o tratamento dos dados coletados ou análise do corpus das respostas das professoras, utilizamos algumas técnicas de análise de conteúdo sugeridas por Bardin (2011). Os resultados deste estudo indicam que no contexto escolar são estabelecidas atitudes docentes ambivalente com os alunos Surdos, isto é, ora as atitudes Eu-Tu são instauradas no seio dessa interação, sendo que em muitos momentos ocorrem as atitudes Eu-Isso por parte de outros professores para com os alunos Surdos. Neste estudo concluímos que a escola precisa se posicionar de maneira crítica, em relação às atitudes Eu-Isso, que reproduzem as barreiras comunicacionais entre Surdos e ouvintes, em contrapartida precisa se tornar um ambiente de relações Eu-Tu, visando o respeito às diferenças linguísticas do aluno Surdo.
ENTRE HEIDEGGER E BAKHTIN: Discussões filosófico-discursivas sobre o Ser e a Linguagem
Authors: De Santana Wilder Kleber Fernandes , Diniz e Silva Helcia Macedo de Carvalho
Published: November 2024

Este trabalho se propõe a analisar os discursos filosóficos de Heidegger e Bakhtin, especialmente no que respeita às concepções sobre o ser e a linguagem. Para constatar as relações dialógicas entre os filósofos é preciso resgatar os discursos proferidos pelos eles no âmago de uma construção filosófica sobre o ser, o que se dá na materialidade dos textos, pelo pensamento e pela linguagem. Trata-se de uma pesquisa bibliográfica, por meio da qual incidimos olhares linguístico-científicos sobre a correlação existente entre as obras Ser e Tempo (HEIDEGGER, 1979) e Para uma filosofia do ato responsável (BAKHTIN, 2010). Alguns resultados desta pesquisa apontam para o fato de que Bakhtin, ao reenunciar escritos heideggerianos, reelabora a concepção de ser e de linguagem. Enquanto na base epistemológica de Heidegger, o ser era primado pelo pensamento, na compreensão de Bakhtin, em diálogos com Volóchinov, o ser se constitui no sujeito e na alteridade, pela linguagem e na interação viva entre os sujeitos falantes e suas consciências, nas relações dialógicas de enunciados de naturezas histórica, sócio-interacional, ideológica e linguística.
UM DIÁLOGO COM VOLÓCHINOV E FREIRE SOBRE ALTERIDADE, EDUCAÇÃO E LINGUAGEM NO CONTEXTO DAS FRONTEIRAS LINGUÍSTICAS PARA A AQUISIÇÃO DO PORTUGUÊS COMO LÍNGUA ADICIONAL NA AMAZÔNIA BRASILEIRA
Authors: Câncio Raimundo Nonato de Pádua
Published: November 2024

O objetivo deste estudo é identificar aproximações teóricas entre Volóchinov (2017) (Círculo de Bakhtin) e Freire (1991), a partir de suas reflexões sobre alteridade, educação e linguagem, para verificar de que forma esses autores contribuem para um olhar crítico sobre as fronteiras linguísticas vivenciadas pelos povos indígenas Wai-wai (Karib), na aquisição do português como língua adicional na Amazônia brasileira. Metodologicamente, caracteriza-se como um Estudo de Caso do Tipo Etnográfico, cuja abordagem é qualitativa, realizado na Aldeia Mapura, junto a cinco sujeitos indígenas, utilizando-se como recurso de pesquisa a entrevista semiestruturada. Os dados foram analisados a partir de duas subcategorias analíticas: manipulação do discurso e negação da alteridade; e posição de poder e resistência na inserção social, as quais dialogam com categorias: alteridade, educação e linguagem. O estudo faz aproximações como a base teórica de reflexão Análise Crítica do Discurso (FAIRCLOUGH, 2001). Os resultados mostram que os povos indígenas Wai-wai resistiram historicamente à manipulação do discurso e à negação da alteridade, engendrados pelos missionários norte-americanos, ocupando, nessa relação, um lugar de poder e resistência contra as ideologias monolíngues, levando-os a desenvolver estratégias comunicativas que lhes auxiliaram na aquisição da língua portuguesa como língua adicional.
A TEORIA DA DIALOGICIDADE EM MARTIN BUBER E PAULO FREIRE: APROXIMAÇÕES E DIVERGÊNCIAS CONCEITUAIS
Authors: Oliveira Waldma Maíra Menezes de , Oliveira Ivanilde Apoluceno de , Matos Lyandra Lareza da Silva
Published: November 2024

ResumoEste artigo tem como eixo principal a análise sobre a dialogicidade no pensamento educacional de Paulo Freire e Martin Buber, isto é, versará sobre a categoria diálogo como elemento central. A pesquisa objetiva realizar um estudo comparativo sobre as teorias da dialogicidade dos dois pensadores. Trata-se de uma pesquisa bibliográfica, cujos procedimentos metodológicos são o levantamento bibliográfico e a sistematização e análise dos dados, na qual se utilizou a técnica da Análise de Conteúdos. O uso da comparação, enquanto perspectiva de análise possibilita realizar aproximações e discordâncias presentes na base epistêmica Freireana e Buberiana. Os referenciais mais representativos foram: Freire (1979, 1980a, 1980b, 1996, 1997, 2007 e 2017); Buber (2012); Querette (2007); Zuben (2012) e Schneider (1998). A concepção freireana de educação é reconhecidamente uma referência nas práticas educativas no contexto brasileiro, por outro lado o pensamento educacional Buberiano não é tão disseminado, apesar de sua grande contribuição para a educação. Identificamos pontos de aproximações e de afastamentos entre esses dois autores em termos da teoria da dialogicidade em suas dimensões existencial, ético-política e educacional. Todavia, não se trata de realizar uma problematização sobre qual concepção é melhor visibilizada, pois além de questões de construções teóricas particulares, os autores vivenciaram épocas e contextos diferentes. Assim o mais interessante é entender a contribuição que ambos trazem para o campo educacional, consequentemente para a vida humana. Palavras-Chave: Diálogo; Educação; Paulo Freire; Martin Buber
O PORQUÊ É PRECISO ALTERIDADE: a subjetivação do neoliberalismo sobre os sujeitos
Authors: Kosvoski Deysi Maia Clair , Silva Sara Farias da
Published: November 2024

Este artigo apresenta uma abordagem crítica, política e filosófica com conceitos importantes para a análise da alteridade sobre a subjetividade e subjetivação do sujeito, em contexto neoliberal. Nosso objetivo é problematizar o contexto atual e analisar a responsabilidade docente quanto a evolução dos sujeitos no aspecto humano no processo educacional, perspectivando relações de alteridade em um mundo comum, o espaço físico ou teórico ocupado por sujeitos em interação. A partir da realidade sócio histórica na qual estamos inseridas, queremos discutir a questão problemática: Como provocar o sujeito a educar-se para a alteridade em contexto neoliberal no qual o sujeito está subjetivado à competição e ao empresariamento de si? Nossos estudos contribuem à medida que fazem questionamentos em relação ao humano e ao futuro da humanidade para que sejam proporcionados aprendizados sobre e com alteridade e que com isso, possamos reconhecer o outro como nosso semelhante, mas não só o próximo, o desconhecido, aquele que está longe dos olhos e que só a alteridade pode desencadear a percepção dos sentidos a respeito e reconhecimento desse outro.
NOS PENSAMOS COMO DOCENTES CON PAULO FREIRE: una experiencia de formación dialógica y autobiográfica
Authors: Rivas Flores José Ignacio , Moreno Parra Jesús Javier , Márquez García María Jesús
Published: November 2024

Presentamos una experiencia de formación inicial del profesorado de enseñanza primaria y del grado de pedagogía, en la Facultad de Ciencias de la Educación de la Universidad de Málaga, a partir de la lectura de obras de Paulo Freire. Mediante el diálogo, a través de tertulias dialógicas, nos pensamos colectivamente como profesores y estudiantes, junto a Freire. El proceso de lectura compartida nos ayudó a interpretar y repensar el funcionamiento de las instituciones escolares, el valor de la educación para la transformación del mundo, de los sujetos y de la sociedad. Igualmente nos permitió profundizar en la dimensión política de la educación, así como de nuestras acciones como docentes. Esto tiene más sentido en un contexto de desmovilización social de los distintos colectivos y el intento neoliberal de protocolización y tecnocratización de la práctica educativa. La experiencia de formación político-educativa que compartimos en este artículo transita por dos momentos que se entrelazan: el diálogo colectivo a través de las tertulias dialógicas y el relato autobiográfico personal. De esta forma se intenta dar un sentido complejo a lo que vivimos en el pasado como alumnado en la escuela, en el presente en la formación universitaria y nuestra proyección como futuros docentes.

Mobilidade urbana para a inclusão da pessoa com deficiência (PCD)
Authors: Grubba Leilane Serratine , Pissolatto Luciano
Published: November 2024

A pesquisa tem por objeto a inclusão urbana das pessoas com deficiência (PcD). Pessoas com deficiência desenvolvem todas as suas atividades dentro do ambiente urbano, preferencialmente em igualdade de acesso e oportunidade para com pessoas sem deficiência. Partindo desse pressuposto, busca-se compreender os mecanismos legais que protegem e fomentam os direitos de mobilidade para PcD. Em especial, analisa-se os aspectos da recepção da Convenção sobre Direitos da Pessoa com Deficiência (ONU); e busca-se estabelecer um conceito mais abrangente e menos discriminatório de necessidade diversa, em detrimento de necessidade especial. A pesquisa desenvolve-se pelo método dedutivo. Apresenta como discussão que o direito à mobilidade das pessoas com deficiência é garantido por norma assemelhada a constitucional; portanto, um direito humano fundamental; ainda, é regulamentado por lei específica que protege e dá guarida à pretensão. A mobilidade urbana afeta as gerações atuais e vindouras, independente de portar ou não deficiência, pois considera que em algum momento da vida todas as pessoas apresentarão mobilidade reduzida. Logo, pensar no amanhã com edificações e com desenhos universais gera inclusão no ambiente das cidades.
Accountability, Governança e Teoria do Cisne Negro: impacto da estratégia de flexibilização dos contratos públicos para enfrentamento à crise gerada pela pandemia da COVID-19

Published: November 2024

O estudo relaciona princípios do neoconstitucionalismo e de boa governança como base da investigação. Descreve o problema presente na responsabilidade da gestão pública com o dever de administrar a imprevisível crise decorrente do Coronavírus de modo responsável e satisfatório. Desenvolve a pesquisa apontando as principais mudanças que a sociedade precisou se submeter após decretação de calamidade pública causada pela COVID-19, equiparando a situação à teoria de Nassim Nicholas Taleb intitulada como a Lógica do Cisne Negro. Postos os elementos metodológicos teóricos, o trabalho volta-se a analisar a relação entre governança, accountability, corrupção em um cenário atípico marcado pela pandemia da COVID-19. A investigação pauta-se em revisão de bibliografia, que propiciou a estruturação de uma análise lógico-dedutiva da norma e comparativa das informações empíricas fornecidos pelos órgãos públicos. Conclui-se que, a corrupção no Brasil está muito vinculada a burocracia e a ausência de punição efetiva, o que reforça a necessidade de consolidação da boa governança como instrumento de defesa dos interesses sociais e limitador das práticas corruptivas.

Published: November 2024

Introduction:

The aim of this observational study was to investigate the risk factors of a failed first attempt at pediatric central venous catheter (CVC) placement and its impact on CVC-related morbidity.

Materials and Methods:

In this prospective observational study, we included 3-month-to 5-year-old children proposed for infraclavicular subclavian vein catheterization consecutively sing the anatomic landmark technique. Patients were divided into two groups: group 1 included single-attempt catheter placements, and Group 2 included failed first attempts at catheter placement. The management protocol was standardized for all patients. After comparing the two groups, univariable logistic regression was used to investigate the risk factors for a failed first attempt and to show the interest of the single-attempt catheter placement.

Results:

Among 150 pediatric CVC placements, the incidence of failed first attempts was 41.3% and its main risk factors were children with comorbidities (OR=3.11; 95%CI: 1.17–8.21), hematology and oncology patients (OR=5.6; 95%CI: 2.75–11.38), children with aplastic anemia (OR=3.05; 95%CI:1.388–6.705), and anesthesia sedation with I-Gel airway ventilation (OR=9.21; 95%CI: 1.080–78.5). On the other hand, a single-attempt catheter placement was a protective factor against catheter-related complications with OR=0.258 [0.12–0.55].

Conclusion:

It seems that a single-attempt CVC placement may reduce the incidence of complications. The knowledge of the main risk factors of failed first attempts is mandatory for taking necessary precautions.
“ARE YOU READY TO BEAR WITNESS?": MEMORY OF CINEMA IN THE SILENCE OF OTHERS
Authors: Kaya Arda
Published: November 2024

Since their first screenings, motion pictures have also functioned as documents. This recording of life is also an emphasis on the witnessing feature of cinema. Through movies, societies are witnessed to events that they usually do not witness through scenarios or documentary images. And documentaries are one of the film genres that enable witnessing in this way. The documentary film “The Silence of Others” (Carracedo and Bahar, 2018) tells the story of people who witnessed the social traumas during the Franco era in Spain and their struggle against the “Pact of Forgetting” in the country. The director is also involved in this process. This situation is important in showing how social traumas are represented in cinema and how films turn into a tool of remembrance. As a result of the research, important conclusions were reached about how cinema as a means of documentation witnesses societies to narratives about the past. One of the most important things that can be suggested based on this study is that narratives of the past should be examined not only as narratives of the past but also as narratives of the future.

Inulin is a particularly effective drug delivery vehicle as compared to other biodegradable polysaccharides because of its unique and flexible structure, protective and stabilizing properties, and organ targeting abilities. This strategy may result in targeted, delayed, and regulated release of medications and biomolecules as well as increased bioavailability and improved cellular absorption. In the present study, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), 1H-NMR, and ultraviolet spectroscopy were among the techniques used to further characterize the physicochemical properties of inuline. The inulin-g-[N-sulfamethoxazole maleic amic acid] (INMS) was prepared and used. INMS efficacy against bacterial activity was also examined. In order to examine the activity of INMS in vivo, mice were underwent to second-degree burn. The results showed, after three days, the basic media produced better regulated drug release than the acidic one. This was discovered by contrasting the pace at which the amide drug polymer hydrolyzed in each media. It was discovered that a drug polymer with altered drug release and a prolonged duration of action has as an adhesive probity. The present results found that INMS has a significant antibacterial effect on burned wound isolated bacteria. The in vivo performance using a natural polymer as a drug carrier results a great healing of skin wound of mice. Thus, the present study is aimed to modify the inulin to serve as a scaffold for various drug delivery systems.

Abstract. Hieu HK, Minh NV, Loi NV, Ha HT. 2024. Application of DNA barcode for the genetic analysis and identifying a May nuoc mo species in Quang Nam Province, Central Vietnam. Biodiversitas 25: 3299-3308. Precise identification in Calamus, the genus in the subfamily Calamoideae (Arecaceae), is challenging due to taxonomic complexities. This study aimed to discriminate and identify the 23 May nuoc mo samples collected from Quang Nam, Vietnam using four barcoding regions (rbcL, matK, psbA-trnH, and ITS nrDNA) and combined with morphological characters. DNA sequence data from those regions were analyzed using distance, tree, and similarity-based statistical methods. All region sequences presented no variable sites, except for rbcL gene region with a low rate of nucleotide differences of 0.270%. The results of the 23 May nuoc mo samples were highly similar from 99.73 to 100% to Calamus sp. N_XT142 (ON248649.1 and MK692404.1) and no gene regions were proposed as barcodes for species identification in this study. All samples shared certain morphological characteristics, including leaflets arranged regularly but with gaps; petioles with yellow spine groups; and leaf sheaths with hairs, densely arranged with brown, triangular, and flattened spines, and interspersed among many short, and black spines. Based on these results, we recommend using some other gene regions (rpoC, and rpoB)) in species identification to shed more light on these May nuoc mo samples with subsequent studies.

Community structure and biomass of reef fish concerning coral cover in Sempu Strait, East Java, Indonesia. Biodiversitas 25: 3376-3385. Reef fishes were used as bioindicators of biodiversity in coral reef ecosystems. However, coral cover and reef fish abundance around Sempu Strait tended to decrease. The study aims to obtain reef fish's community structure and biomass and their correlation to coral cover. We observed significant variability in reef fish populations through bi-monthly monitoring using an underwater visual census and underwater photo transect conducted from December 2022 to April 2023. Based on these observations, the average range of coral fish abundance was 0.453 to 0.577 individuals per square meter, with the highest value at Rumah Apung station (0.577 ind/m2). The community structure included 81 reef fish species, categorized into major (50 species), indicator (10 species), and target (21 species) groups, demonstrating a community with moderate diversity, stable evenness, and low dominance across the observed stations. Further, the research quantified fish biomass, recording an average of 0.0207 kg/m2 or 207.571 kg/Ha, categorized as low, with the highest biomass measurements at Rumah Apung station (0.0054 kg/m2). Strong correlations were identified between coral cover and both fish abundance (correlation coefficient = 0.741) and biomass (correlation coefficient = 0.666). These results emphasize the profound impact of coral health on the conditions and sustainability of reef fish populations. These findings underscore the critical dependency of reef fish on coral ecosystems and provide essential data for conservation efforts to maintain and restore these vital marine habitats.

Abstract. Putro SP, Haqi MDA, Muhammad F, Hariyati R, Helmi M. 2024. The influence of different substrate types on the diversity of macrofouling organisms at the submerged coastal ecosystem of Karimunjawa Islands, Indonesia. Biodiversitas 25: 3394-3400. Colonizing fouling organisms exhibit taxonomic diversity and distribution in response to environmental variability of the submerged marine ecosystem. This study compares macrofouling organisms found on various substrate types at Menjangan Besar Island, Karimunjawa, Central Java, Indonesia which were varied from coarse to smooth surfaces in the water column. The consisted of High-Density Polyethylene (HDPE) cage framework (3 stations) and lower part of a wooden ship hull are the smooth ones (3 stations), and concrete block at the Menjangan Besar Island dock is the coarse ones (3 stations). Sampling of macrofouling organisms was collected from the substrate within 0.25 m2 area at each station with the purposive random sampling method. Identification of macrofouling organisms was done under Canon MZ25 stereomicroscope. We identified 15 species from 7 classes from Menjangan Besar Island. The most dominant species on concrete blocks was Septifer sp. (96 ind.m-2), on the ship’s hull was Littoraria sp. (416 ind.m-2), and on the cage framework was Crassostrea angulata Thunberg 1793 (240 ind.m-2). The diversity index (H’) of fouling organisms ranged from 0.69 to 1.82, while the evenness index (e) ranged from 0.25 to 0.67, and the dominance index (C) ranged from 0.24 to 0.51. Differences in index values are likely due to factors related to food source distribution and substrate types. Salinity, temperature, and turbidity were the physical-chemical water parameters significantly affecting fouling organism distribution (BIO-ENV, Primer 6.1.5; Corr. value (r)=0.722). Anthropogenic activities such as aquaculture, fishing and tourism in the area are suspected to influence hydrodynamic changes, subsequently affecting the fouling organism attachment and colonization processes, especially organic matter generated from marine culture activities.

Abstract. Openg EBL, Santosa Y, Jaya INS. 2024. Analysis of the relationship between the population size of Kalimantan orangutan (Pongo pygmaeus) and land cover changes in Central Kalimantan, Indonesia. Biodiversitas 25: 3468-3475. Land cover change, a major driver of habitat change, significantly influences the distribution of wildlife species, including the Kalimantan orangutan (Pongo pygmaeus Linnaeus, 1760) in Central Kalimantan, Indonesia. This analysis, aimed at quantitatively assessing the relationship between changes in land cover and the population of Kalimantan orangutans in 2014-2019, underscores the urgent need for orangutan conservation. Using data on the population of Kalimantan orangutans and updated Landsat images with land cover data from the Indonesian Ministry of Environment and Forestry, we conducted a multiple linear regression analysis to unveil the relationship between the two. The research results from three specific conservation area locations reveal a decrease in the orangutan population in Lamandau, with the largest increase in open land cover types, a trend largely influenced by anthropogenic factors. Conversely, an increase in population was observed in Sebangau, with the largest increase in the swamp land cover type, and population fluctuations occurred in Tanjung Puting, with the largest increase in the open land cover type. The decline in the orangutan population is attributed to anthropogenic factors and natural predators, while the population increase occurs naturally and through orangutan reintroduction activities. The analysis concludes that secondary swamp forests, bushes, and open land cover are closely related to the size of the Kalimantan orangutan population at the research location, thereby highlighting the urgency and concern for orangutan conservation.

Abstract. Adinugraha F, Zubaidah S, Lestari SR, Chua KH. 2024. Ethnobiology of plants and animals used as ubarampe in the Kepungan tradition of the Javanese Community of Somongari, Purworejo District, Indonesia. Biodiversitas 25: 2521-2532. The Somongari Javanese community of Purworejo District, Central Java Province, Indonesia utilizes plants and animals as traditional ritual equipment, called ubarampe, which are offerings in the Kepungan tradition. The concept of ubarampe, comprising plants and animals, holds a distinct purpose and philosophical significance for the Somongari Javanese community. Unfortunately, knowledge about ubarampe in the Kepungan tradition has only been transmitted through oral and demonstration, and not yet been recorded in written and visual documentation, resulting in the younger generation being unaware of the use of plants and animals for ubarampe and their associated philosophical meanings. This study examines the ubarampe in the Kepungan tradition, including the types and their philosophical meanings as well as the plants and animals utilized. This study documented 19 types of ubarampe used by Somongari Javanese community in the Kepungan tradition, each of which utilizes plants and animals. Some plants and animals require cooking first, while others are directly used as ubarampe without cooking. The plant specimens utilized in ubarampe include eudicots (10 species), monocots (11 species), and magnoliids (1 species). The botanical components include leaves, flowers, seeds, fruits, bulbs, tubers, and rhizomes. Only one animal species from the Aves class was utilized for ubarampe. The utilization of species in ubarampe is the result of philosophical considerations of the ancestors of the Somongari Javanese community regarding the relationship between humans, nature, God, and ancestors. Consequently, the findings of this research are anticipated to facilitate an enhanced comprehension of plant and animal biodiversity as a valuable cultural legacy for present and future generations.

Abstract. Bahtiar, Jiwani YE, Findra MN, Ishak E. 2024. Temporal variation of peanut worm (Siphonosoma australe-australe) reproduction in Toronipa Beach of Southeast Sulawesi, Indonesia. Biodiversitas 25: 2533-2540. The peanut worm Siphonosoma australe-australe in Toronipa Beach, Konawe District, Southeast Sulawesi, Indonesia is constantly facing ecological pressure. However, a limited understanding of its reproductive pattern hinders the development of a management plan. This study aimed to determine the sex ratio, GML (Gonad Maturity Level), GSI (Gonad Somatic Index), and the size of the peanut worm at early gonad maturity in Toronipa Beach, Southeast Sulawesi, Indonesia. Worms were collected using a hand spade, and the length and weight were measured using a ruler (accuracy of 0.5 cm) and an analytical balance (accuracy of 0.0001 g), respectively. Dissection was then conducted to observe eggs and sperm in the coelom. Additionally, water quality measurements were taken simultaneously with worm sampling. A total of 467 peanut worms were collected, and data were analyzed using standard formulas. The results showed that during the 11-month duration of this study, the sex ratio of peanut worms was imbalanced, as females were more than males. Aside from being dioecious, these worms were hermaphroditic and parthenogenous; the gonad maturity analysis showed various stages (I-IV) in peanut worms throughout the study. The highest level of gonadal maturity for male and female peanut worms was observed in August and September at Toronipa Beach. The first gonad maturity for male peanut worms occurred at 12.4-13.4 cm, while females matured at 13-13.5 cm. Throughout the year, gonad maturity and spawning were supported by environmental factors, such as temperature and organic matter that ranged from 30-32°C and 2.06-4.31 mg/L, respectively. Reducing harvesting activities during the peak spawning months is recommended to maintain the peanut worm population.
The situatedness of dilemmas in boundary spaces: uncovering paradoxical conditions for increasing effectiveness through transdisciplinary research approaches
Authors: Palmer Henrietta , Polk Merritt , Raviola Elena
Published: November 2024

Organising ‘boundary spaces’ has become a practice for tackling wicked issues in societal planning. Such spaces bring together diverse actors to intentionally staged problem formulation and management processes. However, despite clear goals, boundary spaces face challenges. Moreover, the processes often generate dilemmas and paradoxes that participating actors are incapable of managing within the boundary space itself. In some situations, such tensions can amplify challenges or prevent results from impacting participating organisations. Using a transdisciplinary (TD) research approach, the aim of this article is to develop a better understanding of the different dilemmas and paradoxes that surround or arise within boundary spaces and thereby contribute to increasing their effectiveness in tackling the issues they were created to address.

This article originates from a TD research project that investigated four different boundary spaces of societal planning and research in Sweden. The project employed an iterative TD process that combined theoretical contributions from planning- and organisation studies with practical experiences from societal planning, and facilitation. The position of boundary spaces as being ‘between’ actors – ‘between’ in terms of representation and decision making – calls for further attention to the situatedness of dilemmas and paradoxes in space and time. Our approach resulted in an analytic framework where the dilemmas and paradoxes of boundary spaces were categorised as contextual, relational, process- or transformation-related. The results point at the relations between what we see as three interrelated tensions that ground the existence and functioning of boundary spaces: the mismatch dilemma, the commoning dilemma and the collaboration paradox.
Resilience: why should we think with care?
Authors: Gregoratti Catia , Linnell Mikael , Caretta Martina Angela
Published: November 2024

Resilience has become a ubiquitous term. Individuals, communities and societies are increasingly called upon to be resilient and build resilience as a way to withstand and bounce back from compound climate-induced shocks, conflicts, health and economic crises. In this provocation we critically interrogate the potential that resilience holds for moving beyond a world marked by crises and widening inequalities. A multidisciplinary corpus of feminist scholarship conceives of resilience as a conservative and deeply exclusionary biopolitical device. Against this background, we argue that expressions of resilience from above and below firmly guided by principles of care can be seen as serving socially and environmentally just ends. We thus encourage scholars, particularly feminist scholars, to continue engaging and engaging more courageously with these two concepts in a collective effort to reclaim resilience as a transformatory device.
From responsibility ping-pong to shared responsibility for 1.5° lifestyles? Examining European stakeholder perspectives

We are currently witnessing a paradox in climate governance (CG): despite growing awareness of the socio-biophysical impacts of current lifestyles, there remains a persistent commitment to high-consumption habits with large carbon footprints. Around this paradox, a debate on responsibility for change has developed. Which actor can and should do what to solve the problem? Simultaneously, however, scholars depict trends towards ‘organised irresponsibility’ (Beck, 1988) and individual responsibilisation bound to be ineffective in the context of existing structural challenges. The most likely result of such dynamics is a responsibility ping-pong with actors assigning responsibility to each other, which, in turn, invites the question of how it might be overcome. What other forms of talking about and organising responsibility might exist that could provide an actual basis for transformation change? Disentangling discourses around responsibility in CG, thus, is crucial for enabling a shift in consumption patterns and lifestyles that are compatible with the 1.5° Paris climate target. The present article pursues this objective. Building on a multi-method research approach, including stakeholder laboratories, expert interviews, and Delphi workshops across several European countries, it explores to whom and how European stakeholders in CG, specifically governments, businesses and citizens, assign responsibility, what risks and opportunities are involved, and what indications of a potential for game change exist. The findings uncover a complex web of pre-empted responsibility, which frequently leads to pessimism or ineffective strategies. However, the research also identifies some opportunities for organising a shared, justice-oriented and comprehensive notion of responsibility (Young, 2006).

We report a 544-nm Tb3+-doped LiYF4 (Tb:YLF) laser pumped by two ∼488-nm, 2-W InGaN laser diodes in continuous-wave (CW) and cavity-dumped Q-switch operations. We obtained a CW output power of 482 mW with a slope efficiency of 43%. Cavity-dumped Q-switching generated 6-ns pulses with a pulse energy of 40 µJ at a repetition frequency of 100 Hz, resulting in the highest peak power of 6.7 kW ever reported for Tb3+-based lasers, to our knowledge. We analytically examined the influence of excited-state absorption and energy transfer upconversion on the small-signal gain of a Tb:YLF laser and concluded that their influence was negligible under our operating conditions.
Using polarization to estimate surface normals at air–water interfaces for correction of refraction in seafloor imaging
Authors: Peters Enno , Atkinson Gary A. , Stephan Maurice
Published: November 2024

The retrieval of sea surface normal vectors using shape-from-polarization is investigated for the purpose of correcting for refraction at the water–air interface when imaging from above the water. In shallow clear water and overcast conditions, spectral longpass filtering (using a hard-coated 850 nm cut-on wavelength filter) is demonstrated to 1) avoid artifacts from the ground in the measured polarization state, and 2) reduce polarization from water-leaving radiance sufficiently to derive shape information exclusively from the polarization produced by specular reflection. The dependence of the method on meteorological conditions is studied. Measurements are performed with a commercial polarization filter array (PFA) camera. Due to the decreasing PFA efficiency towards the near-infrared, rigorous characterization and calibration measurements were performed and recommendations (e.g., on the f-number) elaborated. Overcoming the paraxial approximation, normal vectors are then retrieved with systematic errors of 0.1∘ (image center) to 0.5∘−0.8∘ (edges/corners) for a flat water surface. An image of the sea floor corrected for surface refraction shows maximum displacements of 10–20 pixels only (corresponding to 0.25∘) with respect to a validation image without water.

Published: November 2024

This paper presents a comprehensive numerical analysis of super-resolution imaging using dielectric microparticles, employing the finite-difference time-domain (FDTD) method to elucidate the mechanisms that enable resolution enhancements beyond the diffraction limit. Our study demonstrates that dielectric microparticles can achieve a resolution of the order of 50 nm in the visible spectrum, surpassing traditional optical microscopy limits. By simulating the propagation of radiation through a microparticle–object system and generating optical images via a backward propagation technique, we reveal critical insights into how microparticles enhance image contrast and resolution. The study also explores the influence of various parameters, such as source coherence and particle–substrate interactions, on the image formation process. Our results not only validate the super-resolution capability of microparticle-assisted imaging but also provide a robust framework for further advancements in optical imaging technologies, with potential applications in fields requiring ultra-high-resolution visualization.
