Ellas articulan un repertorio de protesta novedoso que se adapta e implementa herramientas como el artivismo para llevar a la agenda pública su protesta. El presente análisis retoma una serie de prácticas y artefactos artivistas para su identificación, diferenciación y clasificación como parte del repertorio de acción y comunicación de las MCFM en el marco del 8 de marzo del 2020 en la Ciudad de México.
La adaptación del concepto de aura en el arte a partir de los NFT. Caso: Beeple
Authors: Aguilar Campos Citlaly
Published: January 2023

Los Token No Fungibles (NFT) han traído desde el 2020 una revolución sobre cómo entender la creación y comercialización de obras artísticas. El objetivo del presente texto, es abrir una discusión sobre cómo la tecnología blockchain transforma el trabajo de un artista en un activo digital o NFT, en el cual se integran sellos de autenticidad que fomentan un regreso al concepto de Walter Benjamin sobre el aura, donde la unicidad de una obra de arte es uno de sus principales valores. Se tomará como estudio de caso el sector de la ilustración digital con el artista estadounidense Mike Winkelmann, alias Beeple, quien vendió un NFT de su autoría en más de 69 millones de dólares. A la par que los NFT permiten proteger derechos de autor y abren nuevas posibilidades en el mercado del arte, también traen paradojas sobre la resignificación, la democratización, el papel de los prosumidores y la viralización de contenidos digitales.
TD 2702 - Elasticidades preço e renda da demanda de energia elétrica domiciliar no Brasil
Authors: Souza João Gabriel de Moraes , Pompermayer Fabiano Mezadre , Rabello Gabriel Gouvêa , Eberhardt Isaque Daniel Rocha , Silva Filho Edison Benedito da
Published: January 2023

Este artigo investiga a elasticidade-preço e renda da demanda de eletricidade residencial brasileira no período 2012-2016. As estimativas usam dados em painel de efeitos aleatórios e fixos e função de resposta ao impulso em modelos de vetores autorregressivos (VAR) e de correção de erros (VECM) para análise de séries temporais. Além disso, analisamos os consumidores em duas categorias: consumidor de baixa renda e consumidor B1 (consumidor médio de eletricidade domiciliar). A contribuição mais relevante desta pesquisa é a análise dos diferentes tipos de consumidores e o impacto da mudança nos preços da energia elétrica nesses consumidores. Os resultados da estimativa do painel são menores que a unidade e têm uma relação negativa no consumo para mudanças positivas nos preços. Os resultados mostram que, para o consumidor residencial médio, a resposta da mudança de preço é menos relevante do que para consumidores de baixa renda. Na função de resposta ao impulso, verifica-se que os consumidores de baixa renda respondem mais rápido e de forma mais intensa que a média dos domicílios residenciais a variações no preço da energia elétrica. Pode-se inferir a partir desses resultados que o impacto da mudança de preço da energia elétrica afeta mais intensamente os consumidores de menor renda e menor consumo de eletricidade, em função do seu custo de oportunidade ser mais elevado. Por seu turno, para o consumidor médio residencial, que possui uma demanda maior por eletricidade, a resposta a mudanças nos preços desse serviço é mais inelástica. Isso ocorre porque a eletricidade é um bem mais necessário e também uma parcela menor da cesta de consumo para esse consumidor. O estudo apresenta ainda uma estimativa para a elasticidade-renda da demanda por energia elétrica no Brasil. Embora não faça diferenciação de consumidores em termos de renda, encontrou-se uma relação positiva, inelástica e de alta correlação entre a massa salarial das famílias e seu consumo de energia elétrica. Essa informação pode ser empregada para o aperfeiçoamento de estratégias de formulação e avaliação de políticas públicas e setoriais, robustecendo estimativas de ganhos de bem-estar social e de evolução da demanda de energia elétrica em função da elevação da renda das famílias no tempo.

Durante los últimos años, el tema de la educación superior universitaria en Perú ha adquirido importancia. Este trabajo tuvo como objetivo general describir el contexto histórico-jurídico de la educación superior universitaria en el Perú. Se desarrolló una investigación cualitativa, descriptiva, histórica y documental, fundamentada en el método histórico hermenéutico. Los hallazgos dan cuenta que: 1) En el continente americano, la educación superior universitaria surge por primera vez en el Perú; 2) Dos grandes periodos históricos marcan el recorrido institucional, uno la época de la colonia y otro el periodo de la república, en ambos momentos se deja ver el predominio de la clase privilegiada en el acceso de la educación; 3) Concepción mercantilista de la educación que perdura hasta la actualidad; 4) Influencia en la gestión de la educación por parte de los organismos multilaterales; 5) Corresponde al Estado mediante la Superintendencia Nacional de Educación Superior Universitaria y el Sistema Nacional de Evaluación, Acreditación y Certificación Educativa orientar la gestión de la educación superior. Se concluye que la educación superior peruana marca el inicio de este nivel de formación en el continente americano, el cual, desde sus inicios en la época de la colonia hasta el presente siglo, se ha caracterizado por procesos de exclusión y mercantilización en detrimento de los grupos étnicos y la clase obrera, por lo que la educación como derecho es vulnerable y sujeto a las orientaciones de las autoridades gubernamentales en función de los intereses de grupos privilegiados, para lograr cambiar esta realidad se hace necesario el diseño de un nuevo marco jurídico que fomente un proceso de educación universitaria más humana e inclusiva.

Macrospicules and Their Connection to Magnetic Reconnection in the Lower Solar Atmosphere
Authors: Duan Yadan , Shen Yuandeng , Chen Hechao , Tang Zehao , Zhou Chenrui , Zhou Xinping , Tan Song
Published: January 2023

Solar macrospicules are beam-like cool plasma ejections of size in between spicules and coronal jets, which can elucidate potential connections between plasma jetting activity at different scales. With high-resolution observations from the New Vacuum Solar Telescope and Solar Dynamics Observatory, we investigate the origin of five groups of recurrent active-region macrospicules. Before the launch of each macrospicule, we detect a compact bright patch (BP) at its base where a newly emerging dipole contacts and cancel with the preexisting ambient field. The spectral diagnosis from the Interface Region Imaging Spectrograph at one of BPs reveals signatures of reconnection at the lower atmosphere. Multiwavelength imaging of these BPs show that they mainly occur at the rising phase of the flux emergence and slowly ascend from the lower to the upper chromosphere. Remarkable macrospicules occur and fade out once the BPs appear and decay from the AIA 304 Å images, respectively. We suggest that these macrospicules and related BPs form in a common reconnection process, in which the increasing reconnection height between the emerging dipole and the ambient field results in the observed variations from BPs to macrospicules. Interestingly, most macrospicules show similar characteristics to larger-scale coronal jets and/or smaller-scale spicules, i.e., the rotating motions, the presence of minifilaments and BPs before the eruptions, and magnetic flux emergence and cancellation. We conclude that the formation mechanism of macrospicules should be the same as spicules and coronal jets, i.e., solar jetting phenomena at different scales share the same physical mechanism in association with magnetic reconnection.

On some new results in a pursuit differential game with many pursuers and one evader
Authors: Ibragimov Gafurjan , Egamberganova Omongul , Alias Idham Arif , Luckraz Shravan
Published: January 2023

We study a simple motion differential game with many pursuers and one evader with equal capabilities in $ \mathbb{R}^n $. The control functions of the players are subject to the Grönwall-type constraints. If the state of the evader coincides with the state of a pursuer, then the game is considered completed. If the state of the evader does not coincide with the state of any pursuer at all times, then we say that evasion is possible. We show that pursuit can be completed if a condition on the convex hull of the initial states of the pursuers is satisfied.

Published: January 2023

In this paper, we posit a framework for the investigation of the fixed point problems (FPP) involving an infinite family of $ \Bbbk $-demicontractive operators and the split common null point problems (SCNPP) in Hilbert spaces. We employ an accelerated variant of the hybrid shrinking projection algorithm for the construction of a common solution associated with the FPP and SCNPP. Theoretical results comprise strong convergence characteristics under suitable sets of constraints as well as numerical results are established for the underlying algorithm. Applications to signal processing as well as various abstract problems are also incorporated.

Measurement and Decomposition of Socioeconomic Inequality in Metabolic Syndrome: A Cross-sectional Analysis of the RaNCD Cohort Study in the West of Iran
Authors: Soofi Moslem , Najafi Farid , Soltani Shahin , Karamimatin Behzad
Published: January 2023

Objectives: Socioeconomic inequality in metabolic syndrome (MetS) remains poorly understood in Iran. The present study examined the extent of the socioeconomic inequalities in MetS and quantified the contribution of its determinants to explain the observed inequality, with a focus on middle-aged adults in Iran.Methods: This cross-sectional study used data from the Ravansar Non-Communicable Disease cohort study. A sample of 9975 middle-aged adults aged 35-65 years was analyzed. MetS was assessed based on the International Diabetes Federation definition. Principal component analysis was used to construct socioeconomic status (SES). The Wagstaff normalized concentration index (CIn) was employed to measure the magnitude of socioeconomic inequalities in MetS. Decomposition analysis was performed to identify and calculate the contribution of the MetS inequality determinants.Results: The proportion of MetS in the sample was 41.1%. The CIn of having MetS was 0.043 (95% confidence interval, 0.020 to 0.066), indicating that MetS was more concentrated among individuals with high SES. The main contributors to the observed inequality in MetS were SES (72.0%), residence (rural or urban, 46.9%), and physical activity (31.5%).Conclusions: Our findings indicated a pro-poor inequality in MetS among Iranian middle-aged adults. These results highlight the importance of persuading middle-aged adults to be physically active, particularly those in an urban setting. In addition to targeting physically inactive individuals and those with low levels of education, policy interventions aimed at mitigating socioeconomic inequality in MetS should increase the focus on high-SES individuals and the urban population.

Authors: Ndagijimana Similien , Kabano Ignace Habimana , Masabo Emmanuel , Ntaganda Jean Marie
Published: January 2023

Objectives: Rwanda reported a stunting rate of 33% in 2020, decreasing from 38% in 2015; however, stunting remains an issue. Globally, child deaths from malnutrition stand at 45%. The best options for the early detection and treatment of stunting should be made a community policy priority, and health services remain an issue. Hence, this research aimed to develop a model for predicting stunting in Rwandan children.Methods: The Rwanda Demographic and Health Survey 2019-2020 was used as secondary data. Stratified 10-fold cross-validation was used, and different machine learning classifiers were trained to predict stunting status. The prediction models were compared using different metrics, and the best model was chosen.Results: The best model was developed with the gradient boosting classifier algorithm, with a training accuracy of 80.49% based on the performance indicators of several models. Based on a confusion matrix, the test accuracy, sensitivity, specificity, and F1 were calculated, yielding the model’s ability to classify stunting cases correctly at 79.33%, identify stunted children accurately at 72.51%, and categorize non-stunted children correctly at 94.49%, with an area under the curve of 0.89. The model found that the mother’s height, television, the child’s age, province, mother’s education, birth weight, and childbirth size were the most important predictors of stunting status.Conclusions: Therefore, machine-learning techniques may be used in Rwanda to construct an accurate model that can detect the early stages of stunting and offer the best predictive attributes to help prevent and control stunting in under five Rwandan children.
Mental Imagery: Greasing the Mind's Gears
Authors: Cavedon-Taylor Dan
Published: January 2023

This paper introduces a novel conceptualisation of mental imagery; namely, that is grease for the mind’s gears (MGT). MGT is not just a metaphor. Rather, it describes an important and overlooked higher-order function of mental imagery: that it aids various mental faculties discharge their characteristic functional roles. MGT is motivated by reflection on converging evidence from clinical, experimental and social psychology and solves at least two neglected conceptual puzzles about mental imagery. The first puzzle concerns imagery’s architectural promiscuity; that is, its ability to assist diverse mental faculties and perform many different functions when doing so. The second puzzle concerns how to square imagery’s architectural promiscuity with its psychopathological relevance; that is, its being a maintaining cause, and possibly even a partial constituent, of several psychological disorders, including post-traumatic stress disorder, bipolar disorder and major depressive disorder. Mental imagery helps and harms human psychology to extreme degrees and this is something that calls for elucidation. MGT says that instead of facing perplexing heterogeneities here, we instead face a significant unity. On this score, MGT is argued to be superior to the currently dominant conception of imagery in the philosophical literature; namely, as a perception-like state of mind.
Fictional Names and Co-Identification
Authors: Stokke Andreas
Published: January 2023

This paper provides an account of co-identification with fictional names, the way in which a fictional name can be used to talk about the same fictional character on disparate occasions. I develop a version of the view that fictional characters are roles constituted by sets of properties that is couched within a dynamic understanding of fictional discourse. I argue that this view captures what is right about both so-called name-centric and information-centric approaches to co-identification with fictional names. I show how the dynamic view in addition accounts for a number of uses of fictional names, including fictional uses, assertoric uses, metafictional uses.
A Curious Case of Formative Assessment
Authors: Kozbial Sebastian
Published: January 2023

The educational value of formative assessment (FA) has been widely acknowledged within higher education. At the same time, there is little consensus on what FA entails, or how it should be defined and understood when looking at the Western education system; this is even more problematic when adapted by TNE institutions. This chapter looks at the definition issues together with key characteristics of quality formative feedback, including the role of the student in co-creating feedback, something that is particularly challenging within the context of this chapter, TNE in China. It looks at the most apparent challenges that are associated with FA implementation within a Chinese higher education context, such as educational heritage and a deep-rooted collectivist approach to learning. It also ventures to propose an alternative conception, formative routines framework FRF), to emphasise the importance of student and teacher training when engaging in formative tasks and using these to support the ongoing development of curricula.
Teachers' Role in Enhancing Adult Learners' Sense of Autonomy, Competence, and Involvement in Online Higher Education
Authors: Ala Mamun , Shahid Sehrish , Mahmud Saadia , Kaur Kuldeep , Mohyuddin Syed
Published: January 2023

This chapter draws from the learning from an Australian transnational higher education provider in enhancing adult students' sense of belonging, engagement, and interactions. The literature suggests that student engagement and motivation could be enabled by fulfilling certain needs such as autonomy, competence, and relatedness or involvement. The chapter also explores some strategies that could be adopted by teachers to promote behavioural, cognitive, emotional, and agentic engagement in online adult learners. It is argued that regular customized communication by online teachers using email and learning management systems can promote teaching presence, as well as student engagement and motivation. This approach is in line with the notion of community of enquiry, a social constructivist model of learning process that suggests that educational experience takes place at the intersection of social, cognitive, and teaching presences. Other strategies, namely the effective use of breakout rooms during an online class, the emphasis on reflective learning, and the use of stories in an online classroom, are also discussed.
Scaffolding New Teacher-Trainers Through a Hybrid Co-Training Model From a Transnational Higher Education Perspective
Authors: Al Abri Saif Said Rashid
Published: January 2023

Despite the potentials of collaborative work for enhancing the knowledge, skills, and attitudes (KSA) of professionals, the educational field lacks a clear model for co-training. This article aims to develop a conceptual framework for this collaborative professional development (PD) strategy to help novice teacher trainers (TTs) grow professionally. Although a lot has been written in the educational literature about co-teaching, there are merely few self-reported reflections about the use of co-training, and it is not clear how to adopt it as a tool for TTs' PD. In an attempt to fill in this gap, a proposed co-training model is constructed based on the philosophy of co-teaching, novice TTs' needs in terms of KSA, and their role-competency in the training room. These concepts are integrated to design a co-training model that is expected to help in scaffolding novice TTs. The author argues that this model, if properly implemented, can support novice TTs.

Impact of Hall Effect on the Electromagnetohydrodynamic (EMHD) Flow of Nanofluid Through a Porous Microchannel
Authors: Rana Amalendu , Reza Motahar
Published: January 2023

A theoretical investigation on EMHD flow through a microchannel with porous medium is considered in this chapter. Impact of Hall Effect on the nanofluid flow transport is analyzed by considering the Brinkman momentum equation to govern the flow performance through porous microchannel. Constant pressure gradient and interfacial slip boundary condition at the walls of the microchannel has been considered. The analytical solution for the nanofluid flow has been expressed by considering blood and ferromagnetic nanoparticles. Variations in velocity and skin friction coefficient associated with the combined EMHD flow in porous microchannel has been evaluated in this study. The present investigation reveals that the velocity and the skin friction both are enhanced by the influence of Hall current. Further, it is also observed from the study that the velocity becomes maximum near to the walls of the microchannel due to interfacial slip boundary conditions. To validate the result an excellent agreement is shown by making a comparison with the results of some available scientific literature.
Effect of Social Presence on Behavioral Intention to Social Commerce Through Online Social Capital
Authors: Hossain Md. Alamgir , Yesmin Nirufer , Jahan Nusrat , Reza Syed Muhammad Ali
Published: January 2023

This research aims to observe how social presence influences online social capital and the behavioral intention of social commerce (s-commerce). The online survey with a structured questionnaire is used to collect data and analyzed by a structural equation model (SEM). The authors found that social presence is directly connected with online social capital (bonding and bridging). Social presence is not meaningfully connected to s-commerce intention (sharing and shopping), but the cluster model argues that social presence has a significant connection with social sharing and shopping intention. Online social capital and s-commerce intention are positively related to social interaction, and the results also confirmed that social capital is a complementary mediator. The paper provides different research instructions and guidelines for consumers and scholars. They offer a user-preferred s-commerce environment that is related to helping enterprise proprietors provide personalized services and supporting clients to acquire precious purchase-related information.

Protein malnutrition remains a challenging and unresolved health problem among young children in Sri Lanka. This paper aimed to explore the impact of socio demographic attributes on meat and meat product consumption of young children and the factors that affect to change meat and meat products consumption. A total of 387 students aged 17-18 y from different subject streams in Kandy district, Sri Lanka were interviewed using a pre-tested structured questionnaire. Binary logistic regression analysis was performed to investigate the socio-demographic factors. All factors possibly influencing meat and meat product consumption pattern were summarized into six factors (monetary, nutritional, health, quality, animal welfare, and advertising) using principal component analysis. Ordinal logistic regression analysis was performed for the linear combination of the above six principal components to investigate how those components affected the changes in meat and meat product consumption. The majority of students (82%) consumed both meat and processed meat products and chicken meat had the highest preference (75%) among the meat-eaters followed by beef (25.3%), pork (14.7%), and mutton (9.0%), respectively. Knowledge on meat quality standards, family income, and religion was the dominant socio-demographic factors that affected meat and meat product consumption (P<0.01). The majority of high school students (91%) were in the normal range of body mass index (18.5-24.9). Monetary and advertising factors had a positive and negative impact (odds ratio=1.66 and 0.70) on the changes in meat and meat products consumption, respectively (P<0.01). Proper maintenance of meat quality and further research and development on nutritional aspects targeting healthier meat and meat products could lead to change in the perception of meat consumption of young school children in Sri Lanka.
Porcine Epidemic Diarrhea Virus nsp13 Protein Downregulates Neonatal Fc Receptor Expression by Causing Promoter Hypermethylation through the NF-κB Signaling Pathway

Published: January 2023

Porcine epidemic diarrhea virus (PEDV) is a highly pathogenic porcine enteric coronavirus that causes severe watery diarrhea and even death in piglets. The neonatal Fc receptor (FcRn) is the only transport receptor for IgG. FcRn expressed by intestinal epithelial cells can transport IgG from breast milk to piglets to provide immune protection. Previous studies have shown that viral infection affects FcRn expression. In this study, we showed for the first time, to our knowledge, that FcRn expression can be influenced by methyltransferases. In addition, we found that PEDV inhibited FcRn protein synthesis in porcine small intestinal epithelial cells postinfection. Then, we found that PEDV interfered with the transcription of genes through aberrant methylation modification of the FcRn promoter. DNA methyltransferase 3b (DNMT3b) has been implicated in this process. Using a series of PEDV structural and nonstructural protein (nsp) expression plasmids, we showed that nsp13 plays an important role in this aberrant methylation modification. PEDV nsp13 can affect the NF-κB canonical pathway and promote DNMT3b protein expression by facilitating p65 protein binding to chromatin. PEDV caused aberrant methylation of the FcRn promoter via DNMT3b. The same phenomenon was found in animal experiments with large white piglets. IgG transcytosis demonstrated that PEDV nsp13 can inhibit bidirectional IgG transport by FcRn. In addition, the core region of nsp13 (230–597 aa) is critical for FcRn inhibition. Taken together, to our knowledge, our findings revealed a novel immune escape mechanism of PEDV and shed new light on the design and development of vaccines and drugs.

The activation of lymphocytes in patients with lupus and in mouse models of the disease is coupled with an increased cellular metabolism in which glucose plays a major role. The pharmacological inhibition of glycolysis with 2-deoxy-d-glucose (2DG) reversed the expansion of follicular helper CD4+ T cells and germinal center B cells in lupus-prone mice, as well as the production of autoantibodies. The response of foreign Ags was however not affected by 2DG in these mice, suggesting that B and CD4+ T cell activation by autoantigens is uniquely sensitive to glycolysis. In this study, we tested this hypothesis with monoclonal B cells and CD4+ T cells specific for lupus-relevant autoantigens. AM14 Vκ8R (AM14) transgenic B cells are activated by IgG2a/chromatin immune complexes and they can receive cognate help from chromatin-specific 13C2 CD4+ T cells. We showed that activation of AM14 B cells by their cognate Ag PL2-3 induced glycolysis, and that the inhibition of glycolysis reduced their activation and differentiation into Ab-forming cells, in the absence or presence of T cell help. The dependency of autoreactive B cells on glycolysis is in sharp contrast with the previously reported dependency of 4-hydroxy-3-nitrophenyl acetyl–specific B cells on fatty acid oxidation. Contrary to AM14 B cells, the activation and differentiation of 13C2 T cells into follicular helper CD4+ T cells was not altered by 2DG, which differs from polyclonal CD4+ T cells from lupus-prone mice. These results further define the role of glycolysis in the production of lupus autoantibodies and demonstrate the need to evaluate the metabolic requirements of Ag-specific B and T cells.

Leptospira interrogans are bacteria that can infect all vertebrates and are responsible for leptospirosis, a neglected zoonosis. Some hosts, such as humans, are susceptible to the disease, whereas mice are resistant and get chronically colonized. Although leptospires escape recognition by some immune receptors, they activate the NOD-like receptor pyrin 3–inflammasome and trigger IL-1β secretion. Classically, IL-1β secretion is associated with lytic inflammatory cell death called pyroptosis, resulting from cytosolic LPS binding to inflammatory caspases, such as caspase 11. Interestingly, we showed that L. interrogans and Leptospira biflexa do not trigger cell death in either murine, human, hamster, or bovine macrophages, escaping both pyroptosis and apoptosis. We showed, in murine cells, that the mild IL-1β secretion induced by leptospires occurred through nonlytic caspase 8–dependent gasdermin D pore formation and not through activation of caspase 11/noncanonical inflammasome. Strikingly, we demonstrated a potent antagonistic effect of pathogenic L. interrogans and their atypical LPS on spontaneous and Escherichia coli LPS-induced cell death. Indeed, LPS of L. interrogans efficiently prevents caspase 11 dimerization and subsequent massive gasdermin D cleavage. Finally, we showed that pyroptosis escape by leptospires prevents massive IL-1β release, and we consistently found no major role of IL-1R in controlling experimental leptospirosis in vivo. Overall, to our knowledge, our findings described a novel mechanism by which leptospires dampen inflammation, thus potentially contributing to their stealthiness.

Infection with the protozoan parasite Trypanosoma cruzi elicits substantial CD8+ T cell responses that disproportionately target epitopes encoded in the large trans-sialidase (TS) gene family. Within the C57BL/6 infection model, a significant proportion (30–40%) of the T. cruzi–specific CD8+ T cell response targets two immunodominant TS epitopes, TSKb18 and TSKb20. However, both TS-specific CD8+ T cell responses are dispensable for immune control, and TS-based vaccines have no demonstrable impact on parasite persistence, a determinant of disease. Besides TS, the specificity and protective capacity of CD8+ T cells that mediate immune control of T. cruzi infection are unknown. With the goal of identifying alternative CD8+ T cell targets, we designed and screened a representative set of genome-wide, in silico–predicted epitopes. Our screen identified a previously uncharacterized, to our knowledge, T cell epitope MUCKb25, found within mucin family proteins, the third most expanded large gene family in T. cruzi. The MUCKb25-specific response was characterized by delayed kinetics, relative to TS-specific responses, and extensive cross-reactivity with a large number of endogenous epitope variants. Similar to TS-specific responses, the MUCKb25 response was dispensable for control of the infection, and vaccination to generate MUCK-specific CD8+ T cells failed to confer protection. The lack of protection by MUCK vaccination was partly attributed to the fact that MUCKb25-specific T cells exhibit limited recognition of T. cruzi–infected host cells. Overall, these results indicate that the CD8+ T cell compartment in many T. cruzi–infected mice is occupied by cells with minimal apparent effector potential.

Gamma irradiation treatments have commonly been applied to induce variation in plant genetic improvement programs. The improvement of nyawai (Ficus variegata Blume) is urgently needed mainly to break the seed dormancy, increase seedling growth, and induce variation for selecting desired traits. This research aimed to assess the effect of gamma irradiation doses on seed germination, seedling growth, and leaf morphology of Ficus variegate Blume. This experiment's irradiation doses ranged from 5-240 Gy and were applied to seeds with varying levels of vigor based on the artificial seed aging process. The data displayed a positive relationship between low doses of gamma irradiation and the nyawai seed's endurance. Low irradiation doses, 5 to 30 Gy, are deemed capable of promoting seedling development, leaf retention, and diversity in leaf structure. The higher irradiation doses than 30 Gy decreased seedling growth, leaf number, and seedling survival. In addition, these doses also affect some morphological changes, including seedling height and leaf length and width.

Eastern little tuna (Euthynnus affinis) is a commercially important species for coastal communities in the western and southern part of Indonesia. However, little is known about its characteristics. Therefore, a comprehensive and broader research of its population structure is imminent in response to conserve and manage the fishery sustainably. This study aimed to fill the gap of the lacking information on the stock separation of eastern little tuna within the Indonesian archipelagic waters and its Economic Exclusive Zone (EEZ). Population genetic approaches were used to examine population structure using the mitochondrial DNA (mtDNA) control region marker. A total of 94 samples were collected from nine landing sites between January to September 2020. Polymerase chain reaction (PCR) was used to amplify the samples, and Sanger sequencing was used to sequence them. The findings showed a mean value of 0.922 for genetic diversity (Hd) and 0.009 for nucleotide diversity (π). Both of these numbers pointed to a high level of genetic diversity. A further population analyses using Analysis of Molecular Variance (AMOVA) and Discriminant Analysis of Principal Component (DAPC) confirmed a mixing gene pool with no distinct population structure detected (ΦST value of 0.097 and p-value>0.05).
