Disabilities of Fiction: Reading Madness in Twentieth-Century American Women's Literature
Authors:   , Peterson Erica Lyn
Published: June 2024

In this dissertation, disability theories frame readings of madness in select works by Shirley Jackson, Sylvia Plath, and Toni Cade Bambara. The dissertation explores the relationship between madness and fiction, with the author demonstrating the productive and generative aspects of madness. Close readings of the literary works emphasize the impact of madness on structural and formal elements including narrative perspective, sustained metaphors, and narrative time. In chapter one, I use the disability theory concepts of narrative prosthesis and aesthetic nervousness to read Jackson's The Haunting of Hill House. In chapter 2, I analyze Jackson's We Have Always Lived in the Castle to explore the concept of unreliable narration, observing similarities between the social model of disability and reader-centric theories of unreliable narration. In chapter 3, I explore unhealthy disability and medical treatment in the sustained metaphors of light and darkness in Plath's hospital stories, "Tongues of Stone," "Johnny Panic and the Bible of Dreams," and "The Daughters of Blossom Street." In chapter 4, I use disability history to read narratives of medical institutionalization in Plath's novel The Bell Jar. In chapter 5, I use Bambara's concept of "other kinds of intelligences" to develop a Black feminist methodology for reading mad intelligences in Bambara's novel The Salt Eaters. In the dissertation's conclusion, I note prejudice against madpersons in recent legal policies promoting involuntary psychiatric institutionalization, using Bambara's short story "The Hammer Man" to demonstrate the violence of such policies.

Additionally, this study revealed some aspects of the art education curriculum in Saudi Arabia that integrated a pedagogical approach consistent with the principles of peace education. The research results underscored the need for greater inclusion of peace aspects in the school curricula, suggesting the potential to create a supportive and empowering educational environment. The study contributes to the broader discourse on integrating the art education curriculum in Saudi Arabia into critical pedagogy and peace education and offers practical insights for educators, curriculum designers, and policymakers.
Divergent Thinking Responses: An Evaluation of Substantive Validity under Multiple Scoring Approaches
Authors:   , Smith Kendal
Published: June 2024

Divergent thinking (DT) tasks that solicit responses to open-ended stimuli are the most common form of assessment used in creativity research. Intended to measure creative potential, these tasks present researchers with multiple choices throughout administration and scoring that often result in widely varying scores. This study used a combined dataset from 9 independent samples (N = 1,066) containing DT responses (n = 15,935) to the alternate uses task to evaluate substantive validity under different scoring approaches. Human ratings of creative quality were compared to 11 additional quality scores based on statistical infrequency and semantic distance. Psychometric analyses were supplemented by review of response content to assess conceptual and operational correspondence. Results revealed several inconsistencies between and within scoring approaches, including considerable subjectivity required to group semantically equivalent responses before applying objective frequency rules; low reliability estimates for statistically unique responses; dictionary uses for some prompts scored as unique under 5% and 10% infrequency thresholds; variation in semantic distance scores of responses with similar meanings; and large within-subject differences across scoring types. Substantive review also indicated that how the creative dimension of appropriateness is operationalized can play a sizable role in score differences, such as treatment of responses featuring randomness, humor, fantasy, or cultural references. Recommendations for expanded reporting practices to support substantive validity in future DT research are discussed.

Authors:   , Giron Balmore Bladimir
Published: June 2024

In the pursuit of reliable, efficient, and cost-effective life support systems for NASA's deep space exploration missions, this study explores an innovative variable conductance radiator (VCR) as an alternative CO2 deposition method, capitalizing on phase change temperatures of air components to selectively remove CO2. The research objectives encompass the design, construction, and comprehensive assessment of a prototype VCR. Initial experimental characterization of the VCR prototype, employing water as the working fluid and an ice/water bath as a heat sink, demonstrates its variable conductance capabilities in both capture and recovery modes. The impact of flow rate and inlet fluid temperatures on heat transfer efficiency were studied, offering insights into system optimization. Results are presented detailing thermal performance under various conditions. The study also involves numerical characterization of the VCR prototype employing SolidWorks flow simulation. Comparison of the experimental and numerical results show an acceptable agreement, indicate likely sources of deviation, and encourages further utilization of numerical approach for optimization and scaling. Additionally, an analytical analysis is conducted to find the energy (heat absorption) involved in CO2 deposition, to evaluate various design aspects including radiator panel size and the equivalent thermal resistance of the system, and finally to do a rough optimization of the full-scale radiator design parameters considering heat transfer and pressure loss effects. As part of the investigative process, a preliminary design for the full-size radiator is developed.
Synthesis and Study of Thin Films for Energy Harvesting and Catalysis Applications
Authors:   , Ganesan Ashwin
Published: June 2024

An electropolymerizable zinc porphyrin carrying eight entities of peripheral bithiophene, 4 was newly designed and synthesized. In this design, the bithiophene entities were separated by a biphenyl spacer to minimize ground state interactions perturbing porphyrin π-electronic structure. By multi-cyclic voltammetry, thin-films of 4 were formed on transparent FTO electrode and were characterized by optical, electrochemical and STM measurements. Further, the ability of zinc porphyrin in 4 to axially coordinate phenyl imidazole functionalized fullerene, C60Im both in solution and on the film interface was performed and characterized. Fluorescence quenching of zinc porphyrin both in solution and in the film was observed upon binding of C60Im. Femtosecond transient absorption studies revealed excited state charge separation for the dyad in solution wherein the measured rate of charge separation, kCS and charge recombination, kCR were found to be 2 x 1010 s−1 and 1.2 x 109 s−1, respectively. In contrast, transient absorption studies performed on the dyad in the film were suggestive of energy transfer with minimal contributions from electron transfer. The present study brings out the importance of modulating photochemical reactivity of donor-acceptor dyad in film as compared to that in solution. The electro- and photocatalytic reduction of molecular nitrogen to ammonia (nitrogen reduction reaction, NRR) is of broad interest as an environmentally- and energy-friendly alternative to the Haber–Bosch process for agricultural and emerging energy applications. Herein, we review our recent findings from collaborative electrochemistry/surface science/theoretical studies regarding transition metal oxides, oxynitrides and sulfides as NRR catalysts. We found that, for all metal oxides and oxynitrides specifically, there is no Mars–van Krevelen mechanism and that the reduction of lattice nitrogen and N2 to NH3 occurs by parallel reaction mechanisms at O-ligated metal sites without incorporation of N into the oxide lattice. Additionally, the results highlight the importance of both O-ligation and the importance of N in stabilizing the transition metal cation in an intermediate oxidation state, for effective N≡N bond activation. For transition metal sulfides, various exfoliation treatments are known to yield Sulfur vacancies and DFT calculations corroborate N2 binding to S-vacancies, with substantial π-backbonding to activate dinitrogen. Most of our NRR catalysts were selective to ammonia production without appreciable competing production of H2.

Authors:   , Tang Sihai
Published: June 2024

This dissertation presents novel approaches to optimizing convolutional neural network (CNN) architectures for connected autonomous vehicle (CAV) workload on edge, tailored to surmount the challenges inherent in cooperative perception under the stringent resource constraints of edge devices (an endpoint on the network, the interface between the data center and the real world). Employing a modular methodology, this research utilizes the insights from granular examination of CAV perception workloads on edge platforms, identifying and analyzing critical bottlenecks. Through memory contention-aware neural architecture search (NAS), coupled with multi-objective optimization (MOO) and the Non-dominated Sorting Genetic Algorithm II (NSGA-II), this work dynamically optimizes CNN architectures, focusing on reducing memory cost, layer configuration and parameter optimization to reach set hardware constraints whilst maintaining a target precision performance. The results of this exploration are significant, achieving a 63% reduction in memory usage while maintaining a precision rate above 80% for CAV relevant object classes. This dissertation makes novel contributions to the field of edge computing in CAVs, offering a scalable and automated pipeline framework for dynamically obtaining an optimized model for given constraints, thus enabling CAV workloads on edge. In future research, this dissertation also opens multiple different venues for areas of integration. The modular aspect of the pipeline allows for security, privacy, scalability, and energy constraints to be added natively. Through detailed layer by layer analysis and refinement, this dissertation can ensure that CAVs can fully utilize any suitable edge device for the workload requested to realize autonomous driving for everyone.
Influence of Energy Density (Fluence) on the Microstructure and Magnetic Properties of Additively Manufactured Soft Magnetic Alloys
Authors:   , Varahabhatla Sai Sree Meenakshi
Published: June 2024

Additive manufacturing (AM) procedures involving the fusion of metal powders or wires tend to produce textured columnar grains, which can have positive effects on the magnetic performance of Fe-Si electrical steels in soft magnetic applications. This work focuses on understanding the impact of energy density (fluence) evolution of grain morphology and texture in Fe-3.8wt%Si and Fe-6wt%Si alloys produced by fusion-based AM. The results show that the development of texture in these alloys is promising for transformers and motor core applications. The desired texture observed in these alloys is obtained in one step unlike conventional manufacturing techniques. The alloys with higher energy fluence exhibited columnar grains with preferential growth orientation along <001> along the build axis, while those with lower energy fluences showed growth orientation in <111> direction. Further, the presence of ordered B2, D03 phases observed in AM processed Fe-6wt%Si improved the overall magnetic performance of these alloys. Additionally, due to relatively high saturation magnetization and sustainability at high operating temperatures, Fe-Co-2V (Hiperco) is an attractive alternative for soft magnetic applications. In this study, Fe-Co-2V alloy is successfully manufactured using fusion based AM techniques and was found to exhibit equiaxed grains in the AM processed conditions. The microstructure was found to have a significant influence on the magnetic properties, leading to intriguing microstructure-property connections. This study will cover these links between microstructure and properties as well as how energy density (fluence) affects the microstructure of the two potential Fe-Si and Fe-Co-2V soft magnetic systems.
Understanding the Role of Defects in the Microstructural Evolutions in Metastable β Titanium Alloys
Authors:   , Li Dian
Published: June 2024

Metastable β titanium alloys stand out as prominent candidates for structure materials in aerospace industries due to their light weight and exceptional high strength. This dissertation systematically investigates the microstructural evolutions in the metastable β Ti-5Al-5Mo-5V-3Cr (wt. %, Ti5553) alloy induced by various defects including grain boundary, twin boundary, and dual-phase interface using advanced characterization techniques such as transmission Kikuchi diffraction (TKD), 3D FIB-SEM tomography, and 4D STEM. Firstly, the morphology of grain boundary α precipitates was characterized using quantitative 3D FIB-SEM tomography combined with 3D phase field simulation. Our findings highlighted the critical role of the inclination angle between habit plane of α and grain boundary plane in determining the morphology of grain boundary α precipitates. Secondly, the nanoscale substructures of a novel high-indexed {10 9 3} twin and its influence on the formation of hierarchical α microstructure were studied, employing conventional TEM and aberration-corrected STEM. Thirdly, the early stage α nucleation in Ti-5553 was studied utilizing interrupted heat treatments and ex-situ characterizations via TEM and aberrationcorrected STEM. Our findings indicated that the preformed β/ω interface can act as nucleation sites for α precipitates. Lastly, the microstructure and defects in the direct energy deposited (DEDed) Ti-5553 alloy were investigated. The results demonstrate that the addition of stainless steel 316L can significantly refine the grain size while also introducing different defects.

Authors:   , Exley Trevor Wayne
Published: June 2024

Exploring the advancement of soft and variable impedance actuators (VIAs), the research focuses on their potential for enhancing safety and adaptability in physical human-robot interactions (pHRI). Despite the promising attributes of these technologies, their adoption in portable applications is still emerging. Addressing the challenges hindering the widespread implementation of soft actuators and VIAs, a multidisciplinary approach is employed, spanning materials science, chemistry, thermodynamics, and more. Novel compliant actuators utilizing phase-change materials and flexible thermoelectric devices are introduced, offering improved safety, adaptability, and efficiency. Thermo-active phase change soft actuators, integrating Peltier junctions, achieve precise thermal control and reversible actuation, overcoming traditional Joule heating limitations for more efficient and controlled thermal responses. The research also delves into thermal variable impedance actuators, using viscoelastic polymers like polycaprolactone (PCL) for variable stiffness and damping. This innovation enables rapid adaptation to changing load conditions, enhancing the dynamic performance of VIAs. Key contributions encompass the design of an agonist-antagonist system using thermo-active phase change materials, applications in soft robotic devices such as grippers and locomotion mechanisms, and the implementation of bidirectional heating elements within these actuators. The work also outlines the challenges encountered, such as gravity's influence on actuation and the frequency-dependent properties of PCL, setting the stage for future research directions to advance the field of soft robotics. Through these contributions, the research demonstrates practical applications of soft and variable impedance actuators in pHRI, paving the way for future innovations in soft robotics.
A Study of Hierarchical Risk Parity in Portfolio Construction
Authors:   , Palit Debjani
Published: June 2024

Portfolio optimization is a process in which the capital is allocated among the portfolio assets such that the return on investment is maximized while the risk is minimized. Portfolio construction and optimization is a complex process and has been an active research area in finance for a long time. For the portfolios with highly correlated assets, the performance of traditional risk-based asset allocation methods such as, the mean-variance (MV) method is limited because it requires an inversion of the covariance matrix of the portfolio to distribute weight among the portfolio assets. Alternatively, a hierarchical clustering-based machine learning method can provide a possible solution to these limitations in portfolio construction because it uses hierarchical relationships between the covariance of assets in a portfolio to distribute the weight and an inversion of the covariance matrix is not required. A comparison of the performance and analyses of the difference in weight distribution of two optimization strategies, the traditional MV method and the hierarchical risk parity method (HRP), which is a machine learning method, on real price historical data has been performed. Also, a comparison of the performance of a simple non-optimization technique called the equal-weight (EW) method to the two optimization methods, the Mean-variance method and HRP method has also been performed. This research supports the idea that HRP is a feasible method to construct portfolios with correlated assets because the performance of HRP is comparable to the performances of the traditional optimization method and the non-optimization method.
A Performance Guide for the "Two Quartets for Saxophones" by Guo Yuan (b. 1965)
Authors:   , Lin Yafei
Published: June 2024

This dissertation provides a performance guide for the two quartets for saxophones by the Chinese composer Guo Yuan (郭元, Guō Yuán) (b. 1965): Eyes Creating Sun-Birds (创造太阳鸟的眼, chuàngzào tàiyángniǎo de yǎn), composed in 2012, and The Eyes Threading Through Sun-Trees (穿越太阳树的眼, chuānyuè tàiyángshù de yǎn), composed in 2021. Guo Yuan is a professor in the Composition Department at the Sichuan Conservatory of Music. He is one of the earliest Chinese composers to have created works for the saxophone. These two pieces were chosen because they demonstrate mature compositional skills and high artistic value, representing a refined level of development of Chinese quartets. Significantly, the composer identifies the two quartets as belonging to a specific series of compositions: both pieces are inspired by the Jinsha (金沙, jīnshā) Site and the Sanxingdui (三星堆, sānxīngduī) Civilization. To facilitate a performance guide, the two works have been analyzed. In particular, an analysis of the method whereby Guo manipulates the timbre and texture through the use of the four parts in the ensemble as well as uses traditional Chinese elements to describe the music should help performers to interpret the desired effect of each compositional technique.
"Bottoming for Dummies"
Authors:   , Davis James Phillip
Published: June 2024

This book is a guide to bottoming. There are more ways to do it than you might think. Bottoming may be read as passive and intransitive today, but for most of its nearly six hundred years as a verb, "to bottom" has been active and transitive. One goal of this guide is to activate the passive sense of bottoming by connecting it to a wider linguistic history. If the bottom so wishes, their bottoming may be as transitive as bottoming has ever been. A bottom may bottom their top, not merely for their top. The top may be objectified by its want of a bottom. Another proposition: the top, by topping, is bottoming, too. He must be. By outfitting himself with a bottom, he bottoms himself. This guide proposes a marriage of active and passive, bumming and bottoming, sexual and nonsexual bottoms. It embraces the versatility inherent in "bottom" and seeks enlightenment through the vast, ever-expanding network this word has woven through our language. It aims to bottom you, the reader, around its thesis (i.e., its bottom): Everybody bottoms. Or at least, everybody should.
The Effects of Board Games Using Jigsaw Cooperative Learning on Elementary School Students' Marine Environmental Awareness
Authors:   , Chung Fu-Ling
Published: June 2024

This study aims to strengthen elementary school students' marine environmental awareness through various learning approaches and board game activities. More specifically, jigsaw cooperative learning, game-based learning, and problem-solving learning approaches were used in this study to investigate the marine environmental awareness of elementary school students. A mixed-methods approach was employed to understand the research questions comprehensively. A total of 43 Taiwanese elementary school fifth-grade students in two classes participated in the study. Twenty-three students in Class 1 played the board game as the treatment in the experiment, and 20 students in Class 2 did not receive treatment but read articles. Quantitative data were collected by surveys and analyzed with statistical methods to measure changes in student marine environmental awareness. Qualitative data were collected by letters and interviews and analyzed thematically to understand students' perceptions and attitudes toward marine environmental problems. The results showed that the learning activities did not statistically significantly enhance marine environmental awareness among Taiwanese elementary students. Therefore, this study concluded that using jigsaw cooperative learning board games can improve elementary school students' marine environmental awareness without significant differences. Last but not least, the implications of research and practice and suggestions for future research were also mentioned in this study.
"You might not ever be the same player again": Factors that Affect the Injury Recovery Process for Female College Soccer Players
Authors:   , Holcombe Trevor Michael
Published: June 2024

The injury recovery process is a tumultuous journey many athletes experience in their playing careers. Previous research highlights the importance of injury recovery for collegiate athletes, as a lack of social support leads to mental illness, decreases academic performance, and low levels of self-esteem. Utilizing the theoretical lenses of social support, memorable messages, and the sport ethic, the current study investigated how injuries affect athletic identity, the role that coaches, trainers, teammates, and family members play in the social support process, how injury affects athletes' experience with burnout, and the memorable messages that athletes received during their recovery. Themes emerged from data analysis, including (1) athletic injury affects identity, (2) coaches, trainers, teammates, and family members have a significant effect on the social support process, (3) injuries, long-term involvement in sports, and negative coach interactions are potential causes for athletic burnout, and (4) athletes remember positive feelings related to messages but are more likely to remember the specifics of negative messages. These findings suggest that multiple factors work in tandem to affect the overall injury recovery process for female college soccer players. The paper closes with theoretical implications and real-world practical applications for athletes.
„Strategiczny Kompas” Unii Europejskiej. Większe bezpieczeństwo i skuteczniejsza obrona UE – plan działań do 2030 r.
Authors: Miszczak Krzysztof
Published: July 2024

A “STRATEGIC COMPASS” OF THE EUROPEAN UNION. STRENGTHENED SECURITY AND MORE EFFECTIVE DEFENSE OF THE EUROPEAN UNION – THE PLAN OF ACTION UNTIL 2030
The article focuses on the analysis of A Strategic Compass for Security and Defence of European Union adopted on March 2022 with the perspective of its implementation over the next 5-10 years. The return of war in Europe due to Russia’s aggression against the sovereign Ukrainian state accelerated the start of an intense debate in the EU on building common military defense capabilities of the EU member states and strengthening the issue of defending its interests. The EU must develop it to act independently and must draw conclusions from recent crises by reducing “critical dependencies.” Can the Strategic Compass become a response to threats in the new constellation of forces in the international order and thus a real project for building its own strategic power projection in international relations? The expansion of military component of the implementation of security policy should achieve an equivalent level of intervention in relation to the economic and civilian activities implemented so far as a comprehensive EU approach to responding to external conflicts and crisis challenges of the modern world. Should the EU be a global military power? The EU’s four main priority activities within its “strategic compass” were analyzed in detail: acting, securing, investing, partnership with NATO and the UN and with the countries of the global South; the EU’s security in the context of China and Russia; the “Strategic Compass”; and the EU’s taking greater responsibility for its own security and defense on a regional and global scale.
A Galician about the Valiant Conqueror of Valencia – Praise of James I the Conqueror in the Song of Pero da Ponte
Authors: Merdała Jakub
Published: June 2024

In this paper we present an analysis of the song O que Valença conquereu by the Galician-Portuguese troubadour, Pero da Ponte, dedicated to King of Aragon, James I the Conqueror, composed on the occasion of his conquest of Valencia in 1238. Within the Galician-Portuguese poetic tradition, references to the Crown of Aragon were not frequent, and when they did appear it was usually in a satirical/humorous context. In this article we present the state of research on Pero da Ponte’s potential links with the Aragonese court, and we situate his work in relation to the realities of both the Galician-Portuguese and Occitan poetic traditions. We present a detailed genre analysis of the song, pointing out the need to unify the genological terminology and offering a different perspective on the formal layer of the composition we are studying. We also make a comparison between how the Occitan-speaking troubadours portrayed James I in their works and how Pero da Ponte did, showing how the content of the work, the poetic devices used by the troubadour and the overall tone of the song place it in the group of poems dedicated to King of Aragon.
El catalán en el aula de ELE: una herramienta para la didáctica de la mediación lingüística y cultural y el aprendizaje basado en contenidos
Authors: Ciszewska Katarzyna
Published: June 2024

La mediación, como una de las destrezas que se debería desarrollar en el proceso de la enseñanza-aprendizaje de lenguas extranjeras está presente en los documentos europeos desde hace más de 20 años. Sin embargo, solo a principios de la década de 2020, con la publicación del volumen complementario del Marco Común Europeo de Referencia de las Lenguas, se describió con suficientes detalles como para permitir a los profesores introducir tareas de mediación en el aula. La competencia mediadora está también relacionada con otros enfoques didácticos modernos, como el enfoque plurilingüe y pluricultural, los enfoques plurales, el enfoque orientado a la acción, así como el aprendizaje colaborativo, significativo y basado en contenidos no lingüísticos. El artículo comentará brevemente la relación entre estos enfoques y la mediación pero su objetivo principal será mostrar que es posible usar la lengua catalana para desarrollar la competencia mediadora en las clases de español como lengua extranjera. Para tal fin se presentarán ocho propuestas didácticas: seis sobre la mediación de textos, una sobre la mediación de conceptos y otra sobre la mediación de la comunicación. En las actividades se aprovechará una variedad de materiales didácticos auténticos en catalán (extractos de guías impresas y en video, artículos científicos, la contraportada de una novela, datos gráficos, publicaciones de Instagram, un extracto de un programa de televisión) a los cuales los aprendientes tienen acceso gracias a uno de los enfoques plurales, a saber, la intercomprensión entre las lenguas de la misma familia. Las tareas están destinadas a estudiantes de secundaria o universitarios, así como a adultos que poseen el nivel de español B1 o superior (no es necesario el conocimiento del catalán, pero se recomienda un trabajo didáctico previo relacionado con la intercomprensión).
Path Coherence and Disruption in Routine Dynamics
Authors: Kim Inkyu , Pentland Brian T. , Frank Kenneth A. , Wolf Julie Ryan
Published: June 2024

We use evidence from a disruption of clinical documentation routines to propose a novel, predictive mechanism for routine dynamics based on path coherence. Path coherence refers to the continuity of situational attributes from one event to the next along a path, for example, a set of activities conducted by the same person has high actor coherence. Situational attributes include classic descriptors such as who, what, when, where, and why. To be recognized as a path, a minimal level of coherence is required, but path coherence can vary along a path. For example, in a medical clinic, typical paths flow from place to place (e.g., reception, waiting room, exam room) and involve different clinical staff (e.g., receptionist, nurse, physician). Using latent factor network models, we compare clinical documentation routines in five outpatient clinics before and after a technological disruption (an upgrade to the electronic health record system). We show that coherent paths are up to 14 times more likely to persist and up to 40 times more likely to form than less coherent paths. We use these findings to theorize about the role of path coherence in routine dynamics. Path coherence in narrative networks is like homophily in social networks, but with a completely different underlying mechanism. We discuss the implications of our findings for organizational path dependence, resilience, and inertia.

Authors: Navari Yasaman , Chinnappan Justine , Dawood Thair , Marcus Huda
Published: June 2024

The maze procedure for atrial fibrillation carries risks, including pleural effusion. We report a case of a 54-year-old woman with right-sided pleural effusion post maze surgery, presenting with dyspnoea. Despite treatment, complications arose, including atrial flutter. Prompt recognition and multidisciplinary management led to a favourable outcome. This case underscores the importance of vigilance for rare post-operative complications and highlights the need for collaborative care in optimising patient outcomes following cardiac surgeries. Further research is warranted to refine management strategies for such occurrences.

Authors: Kim Jan Di , Kim Sungjae , Joung Jaewon
Published: July 2024

Purpose: The psychiatric survivors movement, which represents people with mental disorders (PWMD), recognizes the autonomy of PWMD activists and emphasizes peer support and advocacy. However, in South Korea, where this movement is still in its early stages, the activities associated with it are not clearly defined. This paper aims to explore the role identities of PWMD activists and examine their significance.Methods: We conducted one or two in-depth interviews with 12 PWMD activists to gather data. The interviews were designed to uncover the participants’ perspectives on their roles as PWMD activists and their understanding of these roles. Thematic analysis was used to identify common themes.Results: The overall theme that emerged from the role identities of PWMD activists was “one who publicly advocates for the rights of the group while leading colleagues towards personal growth and societal change.” Within this overarching theme, three sub-themes were identified: intrapersonal, interpersonal, and socio-political aspects. In total, we identified 10 sub-themes.Conclusion: Our findings can inform the development of various activities that support the recovery of PWMD, enabling them to assist their peers and advocate for their future interests, while also ensuring that their roles are reflected in policies.

Published: July 2024

Purpose: This study aimed to develop a counseling program called Motivational Interviewing-Cognitive Behavioral Therapy Integrated Counseling Program (MICBT-CP) and evaluate its effectiveness in post-case management of individuals who have attempted suicide.Methods: Twenty-eight participants with a history of suicide attempts and high scores on Beck’s Scale for Suicidal Ideation were divided into three groups: an experimental group (EG), control group 1 (CG1), and control group 2 (CG2). Each group received different interventions: MICBT-CP for the EG, cognitive-behavioral treatment-based case management (CBT-CM) for CG1, and general case management (GCM) for CG2. Measurements of suicidal ideation, depression, hopelessness, problem-solving competence, life motivation, and perceived motivation were taken at baseline (T1), 6 weeks (T2), and 18 weeks (T3).Results: Significant improvements in life motivation, perceived motivation, and problem-solving competence were observed in the EG compared to CG1 and CG2. Moreover, the EG showed significant reductions in suicidal ideation, hopelessness, and depression. The treatment of CG2 with GCM did not yield significant results, indicating the limitations of current GCM in post-suicide attempt case management.Conclusion: The study emphasizes the need for effective programs such as MICBT-CP and improved practitioner skills in post-suicide case management.

Authors: Kwon Oh Young , Kim Heejung , Han Young Ran , Hong Soyun
Published: July 2024

Purpose: This study examines the association between child maltreatment and the perpetration and victimization of intimate partner violence (IPV) in adulthood, exploring the moderating effects of gender, age, and household income level.Methods: This cross-sectional study analyzed secondary data from the 2016 Domestic Violence Survey in South Korea, including 1,765 married individuals aged 65 or younger who responded to key variables. Structural equation modeling was used to analyze associations among the variables.Results: The paths from child maltreatment to IPV perpetration (β=.22, p<.001) and victimization (β=.22, p<.001) were statistically significant. Gender, age, and household income level significantly moderated this relationship. Women under 40 were more likely to be IPV victims than perpetrators. Low-income level increased the likelihood of being both perpetrators and victims. Women under 40 who had experienced child maltreatment and had a low-income level showed different probabilities of being victims or perpetrators of IPV.Conclusion: Our findings highlight the need to mitigate the negative impact of child maltreatment in adulthood by designing specific interventions for vulnerable groups, such as women, younger individuals, and those with low-income levels.

Keberadaan TPA dapat menjadi sumber masalah terkait pencemaran air tanah apabila TPA yang beroperasi tidak didesain dengan baik untuk meminimalisir terjadinya pencemaran oleh lindi. Lindi yang dihasilkan oleh sampah akan terbawa oleh air hujan melalui infiltrasi air hujan dan terbawa aliran air tanah sehingga dapat menyebabkan masuknya pencemar ke dalam sumur-sumur air tanah yang ada di sekitarnya. Pemulihan air tanah yang tercemar besi oleh lindi TPA dapat dilakukan salah satunya dengan metode fitoremediasi. Kajian ini bertujuan untuk menelaah fitoremediasi air tanah tercemar besi pada lahan bekas TPA Keputih Surabaya Kayu apu (Pistia stratiotes) sebagai salah satu tumbuhan hiperakumulator dipilih untuk memulihkan air tanah yang tercemar besi pada bekas lahan TPA Keputih. Fitoremediasi air tanah tercemar besi diterapkan pada skala rumah tangga dengan menggunakan reactor berbahan fiber dan diisi dengan kayu apu sebanyak 84 batang dan waktu tinggal selama 7 hari.

Abstract. Iswati R, Aini LQ, Soemarno, Abadi AL. 2024. Exploration and characterization of indigenous Trichoderma spp. as antagonist of Rhizoctonia solani and plant growth promoter of maize. Biodiversitas 25: 1375-1385. Maize sheath blight disease, caused by Rhizoctonia solani, is the main maize disease in Gorontalo and is widespread from the lowlands to the highlands. The indigenous Trichoderma spp. is known to function as a biocontrol agent while producing secondary metabolites that promote plant growth. The objective of this study was to isolate, select, and identify indigenous Trichoderma strains that act as antagonistic agents and promote maize plants growth. The bulk of the soil samples were collected from the rhizosphere of maize plantations in the lowland (0-300 masl), medium (300-500 masl), and highland (500-1000 masl) regions at several sites in Gorontalo. Trichoderma spp. isolation was carried out using the serial dilution method on Rose Bengal chloramphenicol medium, and the strains were further purified in PDA medium, followed by morphological and molecular identification. The antagonistic effect was assessed using dual culture method. In addition, the plant growth-promoting traits examined were qualitative IAA production, potassium solubilization, phosphate solubilization, and in vivo for maize plant growth promotion. Molecular identification revealed that the indigenous fungal strains were dominated by three species, namely, Trichoderma asperellum, T. virens, and T. brevicompactum. Other strains identified were T. ghanense, T. reesei, and T. dorothopsis. Of the 30 Trichoderma spp. strains, 25 inhibited R. solani more than 50%. All Trichoderma spp. strains can produce IAA qualitatively and dissolve phosphate at different intensities; only one fungal strain namely T. dorothopsis-TZ31LU1, can solubilize potassium. In addition, several indigenous Trichoderma spp. strains were able to increase the growth of maize plants in vivo. Thus, 25 Trichoderma spp. strains had the potential to be developed as biological control agents for maize sheath blight disease as well as plant growth promoters in maize.

Abstract. Nelly N, Hamid H, Lina EC, Yunisman, Rusli R, Yanti Y, Kairunisa M. 2024. Effectiveness of Bacillus spp. from West Sumatra, Indonesia in controlling Spodoptera frugiperda (Lepidoptera: Noctuidae). Biodiversitas 25: 1472-1478. Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is an invasive pest widely recognized for attacking corn plants. This pest was first discovered in early 2019 in West Sumatra, Indonesia, posing a significant threat to agricultural productivity. To control S. frugiperda, local biological agents, namely Bacillus spp., originating from West Sumatra, have been explored as a potential control method. Therefore, this study aimed to obtain Bacillus spp isolates from rhizosphere origin and assess their effectiveness in controlling S. frugiperda in the laboratory. A completely randomized design was used, consisting of five treatments with three replications. The treatments included Bacillus cereus strain MRPLUMBE1.3, Bacillus myocytes strain MRRZLL 2.2, and Bacillus sp. MRTE strain 1.3.3. For comparison, there was a synthetic insecticide (active ingredient chlorantraniliprole) and a control (distilled water). The application of isolate suspension was carried out through larvae feed. The parameters observed included larvae mortality, percentage of formed pupae and adults (imago), number of eggs laid by females, and survival time of adults. The data obtained were analyzed using Analysis of Variance (ANOVA) and tested with LSD at the 5% level. The results showed that Bacillus spp. isolates originating from the rhizosphere effectively controlled S. frugiperda larvae. The best isolate that can be used to control S. frugiperda is Bacillus spp. from Solok. Specifically, Bacillus sp. strain MRTPE 1.3.3 showed larvae mortality ranged between 28.33 and 41.67%, and the suspension affected the percentage of formed pupae (51.66%) and the survival time of adults (4.5-5.8 days).

Abstract. Temaja IGRM, Selangga DGW, Sudiarta IP, Listhiani L. 2024. Antiviral activity of Eucheuma cottonii to control Pepper yellow leaf curl virus. Biodiversitas 25: 1615-1622. The chili pepper plant in Bali is often infected with yellow curl symptoms caused by Pepper yellow leaf curl Indonesia virus (PYLCIV). The virus is always present in the field and no control measure has been found effective to suppress the PYLCIV infection. Control efforts using macroalgae extract have been frequently used and are able to suppress plant virus infection, but no report on its effectiveness in suppressing PYLCIV infection. This research aimed to analyze the effect of Eucheuma cottonii Weber Bosse macroalgae extract in suppressing PYLCIV infection on chili pepper plants in Bali. The observed parameters were symptom changes, disease incidence and severity, virus confirmation by PCR, and phytochemical analysis. Chili pepper plants infected by PYLCIV before E. cottonii application showed moderate to severe symptoms, but after E. cottonii application plants turned symptomless or showed light symptoms. The PYLCIV disease incidence in chili pepper Seret and Pelita8 cultivars before application was 100%, and after application ranged from 45-55%. The PYLCIV disease severity in chili pepper Seret and Pelita 8 cultivars before application ranged between 68-72%, and after application ranged between 25-34%. PYLCV on chili pepper Seret and Pelita 8 cultivar that were treated with E. cottonii produced lighter DNA band compared to positive control (C+). Major compounds found in E. cottonii extract were propanoic acid, ethyl ester; n-propyl acetate; sec-Butyl acetate; Toluene; Bicyclo [4.2.0] octa-1, 3, 5- triene; and styrene. The E. cottonii extract was able to suppress the PYLCIV infection on chili pepper plants.
