Published: January 2025

This study aims to determine the implementation of science learning in forming the awareness of environmental love among grade V elementary school students at SD N 118 Gresik. The method used in this study is qualitative descriptive with source triangulation through observation and documentation and method triangulation through Focus Group Discussion (FGD), carried out on 20 students and homeroom teachers of grade V of SD Negeri 118 Gresik during science learning. The data analysis method goes through several stages: data reduction, data presentation, conclusion, and data verification. The study results showed that the science learning of the material "Humans and Waste" at SD Negeri 118 Gresik gave students an understanding of the types of waste, its impact on the environment, and the importance of waste management through discussions and presentations. Although students show enthusiasm, maintaining environmental cleanliness has not been fully internalized in daily practice, especially in applying the 3R (Reduce, Reuse, Recycle) principle. It appears that science learning has successfully formed the awareness of environmental love among students in class V of SDN 118 Gresik.

Published: January 2025

The motivation to fulfill needs is a primary factor driving every action, including pursuing higher education. This study employed a quantitative-descriptive approach using a survey to map the hierarchy of needs and motivations of students studying at Universitas Negeri Yogyakarta (UNY). The research aimed to identify the primary needs and types of motivation among first-semester students of the Sociology Education Program at UNY for the 2023/2024 academic year. The population consisted of 100 new students, with a sample of 34 students (34%) selected randomly. Data were collected through an online questionnaire and analyzed descriptively using percentages. The findings revealed that most first-semester students were driven by the need for self-actualization (70.6%), while 29.4% were motivated by the need for esteem. Furthermore, intrinsic motivation dominated (82.4%) compared to extrinsic motivation (17.6%). This study concludes that self-actualization needs and intrinsic motivation are the primary factors encouraging new students to study at Universitas Negeri Yogyakarta.

The water deficit effects on growth parameters, protein content and proline level in the Gtaf (Atriplex halimus) plant were investigated using potassium silicate under three drip irrigation regimes (100, 75 and 50% of field capacity). Compared to the control, yield biomass estimated by the dry and fresh weight of the shoot decreased significantly at severe deficit irrigation levels. In contrast, the moderate-level treatment stimulated the growth. The silicate treatments mitigated the adverse effect caused by water deficit but at a moderate level. The concentration of protein in leaves decreased by decreasing water, while the reverse effect was observed with the application of potassium silicate. Medium treated with silicate of potassium increased the proline accumulation in leaves, especially at the higher deficit level. Under the potassium silicate treatment, the proline concentration dramatically rose in response to the higher stress level. At low deficit level, there was a slight, but not significant, decrease in this trait. Based on these findings, Atriplex halimus as an axero-halophytic shrub could be economical to use as animal feed materials and for the rehabilitation and revegetation of water deficit-affected lands.

Black pepper, the king of spices, is grown for its dry berries. Genetic variation and the relationship between yield and yield-linked characters in nine black pepper genotypes were studied. Highly significant differences for all the characters were found in the variance analysis. Maximum GCV and PCV were noted for spike length, dry berry yield and number of berries spike-1. High heritability and genetic advance over the mean exhibited by the genotypes for dry recovery and spike length indicate additive gene effect in the expression of these characters. Dry berry yield plant-1 had a very strong correlation with fresh berry yield plant-1 and dry recovery at both phenotypic and genotypic levels. During path analysis, fresh berry weight and dry recovery percentage showed a high positive direct and indirect effect on dry berry weight. Genotype PRS 161 was found superior in morphological, yield and yield-related characters, followed by SV11 among the different genotypes studied. Fresh berry yield per plant and dry recovery percentage are the most critical factors for enhancing dry yield in black pepper genotypes, while the number of berries per spike plays a significant indirect role.

A study was conducted using 17 Gomphrena genotypes to investigate the rapport of yield traits and their direct and indirect impacts on flower production. Correlation studies revealed that at genotypic level, flower yield per plant recorded significant and positive connotation with number of flowers per plant (0.990) which was accompanied by traits like primary branches per plant (0.848), stem girth (0.835), plant height (0.829), secondary branches (0.812), shelf life (0.742), flowering duration (0.722), inflorescence length (0.718), plant spread in N-S direction (0.685), first flowering (days) (0.671), plant spread in E-W direction (0.667), individual flower weight (0.648), stalk length (0.606) and other traits. Path analysis disclosed that the number of flowers per plant (1.140) had the highest and positive direct impact on flower yield per single plant, followed by the days to first flowering (0.346), individual flower weight (0.217), plant height (0.189), primary branches per plant (0.168), days to 50 percent flowering (0.137), secondary branches (0.127), plant spread (0.006) and inflorescence length (0.002). These traits, especially the number of flowers per plant and primary branches plant, can be chosen as a key indicator for selection criteria along with other traits in Gomphrena breeding programme.

An investigation was carried out to examine the morphological features of molecularly confirmed putative hybrids derived from different cross combinations of sweet orange and mandarin varieties. The results revealed that phenotypic leaf characters of F1 zygotic hybrid seedlings in all the crosses had a simple type of leaf division. The shape of leaves in all the hybrids was either elliptic or lanceolate, without any clear-cut differentiation. Results indicated a significant variation in leaf lamina shape in hybrids, elliptical and lanceolate form was observed in Mosambi ×Mukaku Kishu and Jaffa × Mukaku Kishu, elliptical and obovate leaf lamina type was observed in Mosambi × W. Murcott and Jaffa × W. Murcott cross. Leaf lamina shape in hybrids of Mosambi × Clementine and Jaffa × Clementine was lanceolate and elliptical type. Leaf apex shape that dominates in Mosambi ×W. Murcott hybrids were acute and obtuse types. In Mosambi × Clementine hybrids, acuminate and acute forms were more dominant. Leaf apex that dominates in hybrids of Jaffa × Mukaku Kishu cross was acute and acuminate type. Hybrids derived from Jaffa × W. Murcott cross had acute and obtuse leaf apex. While in Jaffa × Clementine cross, hybrids had acuminate and acute as the most dominant forms. Hybrid progenies derived from all the crosses showed variation for the presence and absence of a spine. Results indicated that spiny hybrids ranged from 0 to 20.00 % whereas spineless zygotic hybrids ranged from 80.00 to 100 % in all the crosses. These potential hybrids may be recommended for commercial citriculture after thorough horticultural evaluation. The information obtained is expected to contribute to the early identification of zygotic hybrid seedlings derived from different cross combinations involving polyembryonic parents like sweet oranges. The valuable information gained from this study may help in shortening the breeding cycle and reduce the costs of the scion breeding programme in sweet oranges.

An experiment was conducted from April 2020 to July 2021 to assess the effects of foliar applications of NPK (0, 0.5, 1, and 2 g/L) alongside two concentrations of GA? and BA (150 and 250 ppm) on the vegetative growth and chemical composition of Ficus benjamina L. under greenhouse conditions. Results indicated that applying GA? or BA with NPK at 1 g/L significantly increased plant height, with GA? showing a greater effect on stem diameter than BA. BA promoted branching, and both BA and GA? at 250 ppm enhanced root length and the fresh and dry weights of leaves, stems and roots. The lognest roots were observed with NPK at 2 g/L, while NPK at 1 g/L resulted in the heaviest fresh root weight. The maximum content of carbohydrate and nitrogen was obtained with 0.5 g/L NPK and there was relatively greater accumulation of potassium in plant treated with 1 g/L NPK The GA3 was more effective than BA in increasing nitrogen and phosphorus content in plants. BA and GA? increased chlorophyll-a and -b, with the combination of BA (150 ppm) and NPK (1 g/L) yielding the highest chlorophyll-b levels. The highest carotenoid content was achieved with NPK at 2 g/L combined with either GA? or BA. Treatment with BA at 150 ppm enhanced the chlorophyll a/b ratio, while GA? at 250 ppm more effectively increased the total chlorophyll-to-carotenoid ratio. These findings suggest that foliar application of NPK at 1 g/L, combined with either BA or GA? (250 ppm), optimizes vegetative growth and enhances the chemical composition of F. benjamina L. under greenhouse conditions, promoting both growth quality and vigor.

A study was carried out in March 2023-January 2024 at the experimental field of the Department of Floriculture and Landscaping, College of Agriculture, Vellayani, Kerala, India, for the standardization of manuring, irrigation and fertilizer level in tuberose hybrid, Arka Prajwal under drip irrigation and fertigation. The experimental layout was carried out in a split-split plot design with four replications of 16 treatment combinations. Main plot consisted of manures, the subplot consisted of irrigation levels and the sub-sub plot consisted of fertilizer levels. Surface irrigation and manual fertilizer application were treated as control. The synergistic effect of poultry manuring, drip irrigation, and fertigation proved outstanding regarding their individual effects and control. The treatment of poultry manure along with drip fertigation of ½ N and full K at IW/CPE 0.8, recorded the highest plant height (65.62 cm) with a greater number of leaves (18.81) at the spike initiation stage. The same treatment noticed the longest spike (104.70 cm) along with greater number of florets spike-1 (47.55). However, greatest yield (89.67 g) was observed in the poultry manure treatment along with drip irrigation at IW/CPE 1 and 100% recommended dose of N and K through fertigation followed by poultry manure along with fertigation of ½ N full P and full K of recommended dose at IW/CPE 0.8. Considering overall performance, the application of poultry manure along with fertigation of ½ N and total K of recommended dose at deficit irrigation proved to be highly beneficial for growth and yield improvement in tuberose hybrid Arka Prajwal.

The present study evaluated the effect of different levels of fertigation with and without black polythene mulch on the yield and physico-chemical characteristics of the pineapple variety “Simhachalam”. The study was conducted on plant and ratoon crops at Precision Farming Development Centre, Odisha University of Agriculture and Technology, Bhubaneswar, India. The experiment followed a randomized block design with seven treatments replicated three times. Treatments included 100, 80 and 60 % of the recommended dose of fertilizers (RDF) applied through fertigation with and without black polythene mulch and a control (100 % RDF applied conventionally without mulch). In the planted crop, fertigation at 100 % RDF with black polythene mulch produced the highest fruit weight without crown (1028.2 g), fruit length (18.4 cm), fruit circumference (37.5 cm), pulp weight (810.2 g), and yield (55.9 t/ha). Additionally, the 80% RDF with mulch treatment achieved the highest T.S.S (15.2 °Brix), T.S.S: titratable acidity ratio (40.1), reducing sugar (4.5%), and total sugar (12.3%). The highest benefit-cost ratio (2.17) was also recorded with 100% RDF and mulch. Similar trends were observed in the ratoon crop. Fertigation at 100% RDF with mulch resulted in the highest fruit weight without crown (932.7 g), fruit length (17.7 cm), fruit circumference (35.3 cm), pulp weight (732.8 g), and yield (46.8 t/ha). The 80% RDF with mulch treatment maintained the highest T.S.S (15.2 °Brix), T.S.S: titratable acidity ratio (33.8), reducing sugar (4.6%), and total sugar (12.1%). The benefit-cost ratio was highest (2.86) for 100% RDF with mulch. Treatments without mulch generally showed lower yields and poorer quality parameters than mulched treatments. The control treatment (conventional method without mulch) also demonstrated significantly lower performance across most parameters. These findings suggest that adopting fertigation with black polythene mulch, even at reduced fertilizer levels (80% RDF), significantly improves yield and quality parameters in pineapple cultivation, making it a cost-effective and productive approach.

Primal Galia type and carrot roots cv. Laguna throughout storage at 5°C and 90-95 % relative humidity for 28 days. The results indicated that all treatments were superior to control treatment in maintaining quality attributes and extending the storability of fruits and roots. However, KMnO4 + silica gel was the most effective treatment in reducing weight loss, color change, O2 consumption, CO2 and ethylene production and maintaining the firmness and total soluble solids of fruits and roots. In addition, delaying the ripening of cantaloupe fruits, reducing the increase of total carotenoid content of fruits, reducing isocoumarin accumulation and gave carrot roots without any bitterness until the end of the storage period. Also, gave an excellent appearance and did not exhibit any changes in the appearance of fruits and roots until the end of the storage period. On the other hand, control treatment gave an unsalable appearance of fruits and roots at the end of storage.

The study was conducted to evaluate five basal doses of silicon (0, 25, 50, 75 and 100 kg ha-1 as SiO2) along with four foliar sprays at 3rd and 6th leaf stages (water spray, 1, 2 and 3% as SiO2) on floricultural traits and leaf nutrient content in gladiolus cv. White Prosperity. The synergetic effect of silicon on the vegetative growth and floricultural traits was noticed as the dose was increased under both methods of application; however, more beneficial effect was recorded under the basal method of application. Basal silicon application at 100 kg ha-1 recorded the earliest spike emergence and flowering (101.68 and 122.42 days) along with maximum plant height (103.91 cm), spike length (79.88 cm), spike weight (15.51 g), vase life (8.75 days) and silicon content (2.04%). Foliar spray at 3% resulted in early spike emergence and flowering (101.53 and 122.28 days) along with maximum plant height (99.33 cm), spike length (82.18 cm), floret size (9.73 cm), spike weight (15.51 g) and silicon content (1.88%). Despite the positive effect of the singular application of silicon, the combined application of soil and foliar method exhibited the most inductive effect on all observed parameters. Silicon application at lower rates improved Cu, Mn, Fe and Zn content in leaves and vice-versa. Hence, it was concluded that silicon fertilization at 100 kg ha-1 along with foliar spray of 3% at 3rd and 6th leaf stage in gladiolus can be considered a production technology of great importance for promoting floricultural traits and nutrient content in gladiolus.

Visibilité et visualité de l’histoire: sur deux iconotextes associés à Nicolas Gueudeville
Authors: Leplatre Olivier
Published: January 2025

Le présent article se penche sur deux livres historiques collaboratifs auxquels Nicolas Gueudeville a apporté sa participation active:
Le Grand Théâtre historique
et l’
Atlas historique
parus tous deux au début du dix-huitième siècle. Ces ouvrages emblématiques sont les occasions de réfléchir aux formes iconotextuelles prises par la science historique au tournant du siècle. Dans leurs différents paratextes comme dans leur scénographie éditoriale, les deux livres développent en effet une approche doublement raisonnée et pragmatique de l’image. Loin de ne s’en tenir qu’à une fonction ornementale, les illustrations, nombreuses et extrêmement variées, qui les accompagnent et sur lesquelles ils s’appuient œuvrent de manière déterminante à mettre en visibilité de l’Histoire. L’image, spectaculaire, mémorative, soutient ainsi les multiples lectures d’événements du passé qu’elle éclaire tout en en restituant la complexité.

Si les
artes historicæ
de la première modernité, reprenant à leur compte une exigence des
auctoritates
antiques, s’accordent pour demander à l’historien de faire connaître les causes et les desseins des événements, apparaît plus spécifiquement au dix-septième siècle l’aspiration à une histoire des
arcana
. Le terme peut s’entendre en deux sens, celui des secrets du gouvernement,
arcana imperii
, selon l’expression de Tacite, et également celui d’histoire secrète: c’est sous le titre d’
Arcana historia
que sont publiés en 1623 les
Anecdota
de Procope. Les deux acceptions peuvent se recouper, dès lors que l’on prête aux événements publics des causes privées. Les appels à une histoire des
arcana
, qui émanent d’auteurs de sensibilités diverses, témoignent du discrédit dans lequel tombe au dix-septième siècle une histoire purement militaire, et de la préférence alors accordée à une histoire politique, pour laquelle l’œuvre de Tacite constitue un modèle. Pour répondre au goût du public, l’histoire des
arcana

We present a joint analysis of transit timing variations (TTVs) and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known TTVs, with a peak-to-node amplitude of ∼2 days, the largest value ever observed, and a superperiod of ~930 days. TOI-4504 b and c were identified in public Transiting Exoplanet Survey Satellite (TESS) data, while the TTVs observed in TOI-4504 c, together with radial velocity (RV) data collected with FEROS, allowed us to uncover a third, nontransiting planet in this system, TOI-4504 d. We were able to detect transits of TOI-4504 b in the TESS data with a period of 2.4261 ±  0.0001 days and derive a radius of 2.69 ±  0.19 R
⊕. The RV scatter of TOI-4504 was too large to constrain the mass of TOI-4504 b, but the RV signals of TOI-4504 c and d were sufficiently large to measure their masses. The TTV+RV dynamical model we apply confirms TOI-4504 c as a warm Jupiter planet with an osculating period of 82.54 ±  0.02 days, a mass of 3.77 ±  0.18 M
J, and a radius of 0.99 ±  0.05 R
J, while the nontransiting planet TOI-4504 d has an orbital period of 40.56 ±  0.04 days and a mass of 1.42

J. We present the discovery of a system with three exoplanets: a hot sub-Neptune and two warm Jupiter planets. The gas giant pair is stable and likely locked in a first-order 2:1 mean-motion resonance (MMR). The TOI-4504 system is an important addition to MMR pairs, whose increasing occurrence supports a smooth migration into a resonant configuration during the protoplanetary disk phase.

We report the discovery of cometary activity in the form of a pronounced tail emanating from Near-Earth Object (523822) 2012 DG61, identified in UT 2024 April 18 Dark Energy Camera images by our AI assistant TailNet. TailNet is an AI designed to filter out images unlikely to show activity for volunteers of our NASA Partner “Active Asteroids” Citizen Science campaign, from which our AI is trained. Subsequently, our archival investigation revealed 2012 DG61 is recurrently active after we found it displaying a pronounced tail in a UT 2018 April 16 Steward Observatory Bart Bok 2.3 m telescope image and UT 2018 May 14 observations by G. Borisov with the 0.3 m telescope at MARGO Observatory. Our dynamical integrations reveal that 2012 DG61, an Apollo dynamical class member, is likely in 2:1 mean-motion resonance with Jupiter. We encourage additional observations to help characterize the activity morphology of this near-Earth comet.
Polycyclic Aromatic Hydrocarbons as an Extraterrestrial Atmospheric Technosignature
Authors: Dubey Dwaipayan , Kopparapu Ravi , Ercolano Barbara , Molaverdikhani Karan
Published: January 2025

Polycyclic aromatic hydrocarbons (PAHs) are prevalent in the Universe and interstellar medium but are primarily attributed to anthropogenic sources on Earth, such as fossil fuel combustion and firewood burning. Drawing upon the idea of PAHs being suitable candidates for technosignatures, we investigate the detectability of those PAHs that have available absorption cross sections in the atmospheres of Earth-like exoplanets (orbiting G-type stars at a distance of 10 pc) with an 8 m mirror of the Habitable Worlds Observatory (HWO). Specifically, we focus on Naphthalene, Anthracene, Phenanthrene, and Pyrene. Our simulations indicate that under current-Earth-like conditions, detecting PAH signatures between 0.2 and 0.515 μm is infeasible. To account for the historical decline in PAH production post the industrial revolution, we explore varying PAH concentrations to assess instrumental capabilities of detecting civilizations resembling modern Earth. We also evaluate telescope architectures (6 m, 8 m, and 10 m mirror diameters) to put our results into the context of the future HWO mission. With these four molecules, PAH detection remains infeasible, even at concentrations 10 times higher than current levels. While larger mirrors provide some advantages, they fail to resolve the spectral signatures of these molecules with significant signal-to-noise ratios. The UV absorption features of PAHs—caused by π-orbital  → π*-orbital electronic transitions—serve as valuable markers, due to their distinct and detectable nature, preserved by the aromatic stability of PAHs. Additional lab measurements are necessary to gather absorption cross-sectional data beyond UV for more abundant PAHs. This may help further in improving the detectability of these molecules.

The rectovaginal septum is a rare location for gastrointestinal stromal tumors (GIST) to occur. The aim of this study was to present a case of synchronous local recurrence of solitary liver metastasis originating from an extra gastrointestinal tumor (E-GIST) of the rectovaginal space.

A 55-year-old woman, with a medical history of a resected meningioma, was referred to our department due to a 5 cm solitary liver metastasis located within the left lateral segment. The patient had undergone a transvaginal resection of a low-risk E-GIST 6 months prior without receiving adjuvant chemotherapy. The patient underwent a synchronous laparoscopic left lateral hepatectomy and a transvaginal resection with posterior vaginal wall reconstruction. Her postoperative course was uneventful and was discharged on the fifth postoperative day. The histological examination of the vaginal lesion revealed the development of neoplasm with pathological characteristics consistent with the initial histology expect for a mitotic index exceeding >20%. Liver histology report also included a high-risk GIST with CKIT (+), DOG1 (+), ki67 ≥30%, high mitotic activity and clear resection margins. The patient was referred for adjuvant chemotherapy.

E-GISTs are rare neoplasms with low malignant potential. However, these tumors may exhibit metastatic potential and require aggressive treatment.

Sur une place, un jardin : étude des médiations spatiales d’un lieu jardinier
Authors: Champalle Louis
Published: January 2025

Cet article propose de montrer que le jardin partagé et l’association qui le gère médiatisent, par l’inscription de la pratique jardinière et de la « nature en ville », des représentations qui portent également sur le milieu dans lequel ils se situent. Ces représentations, issues d’une enquête ethnographique au sein d’un jardin partagé d’une métropole française, permettent de décrire la spatialisation à l’œuvre sous la forme de stratégies formées depuis le lieu vers son milieu, et de tactiques depuis ce dernier vers le lieu, notamment depuis des logiques d’ouverture et de fermeture.
Navigating the Unique Complexities of Dissertation Supervision in Doctoral Nursing Education
Authors: Birnbaum Shira , Zha Peijia
Published: January 2025

Background

Complex educational challenges emerge during Doctor of Philosophy (PhD) dissertation research, yet many newly hired faculty receive little preparation for the role of dissertation supervisor. The intensity and rigor of dissertation supervision are not reflected in workload calculations based on enrollments or clock hours. New faculty have few venues beyond personal experience to learn the challenges that supervision entails.

Method

This article presents reflections of two research methodologists who supervise students in a nursing science PhD program in a large research university. It explores several challenges and dilemmas that characterize the supervision process.

Results

Challenges of supervision involve dynamics of power, authority, and reputational self-protection, which reflect the paradoxical nature of the dissertation process, the distinct structure of graduate nursing education, nonlinear trajectories of doctoral learning, and risks related to the growth of generative artificial intelligence.

Conclusion

Newly hired faculty need to be prepared for the unique challenges of supervising student research.

Boredom and affective temperaments as factors hindering smoking cessation: An exploration within an Italian sample
Authors: Iannuzzo Fiammetta , La Versa Michele , Turiaco Fabrizio , Pandolfo Gianluca , Mento Carmela , Muscatello Maria Rosaria Anna , Bruno Antonio , Lombardo Clara
Published: January 2025

Background

Smoking cessation presents challenges influenced by neurological adaptations and psychological factors, potentially exacerbated by susceptibility to boredom and affective temperaments.

Methods

This study enrolled 409 participants via an online survey distributed among the Italian population through mailing lists, social networks, and messaging apps. Specific questions assessed cigarette smoking, while the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-A) and Boredom Proneness Scale (BPS) explored affective temperaments and susceptibility to boredom, respectively.

Results

Results indicated smokers exhibited higher cyclothymic temperament scores compared to no-smokers and ex-smokers, suggesting a connection between this temperament and smoking behavior. Furthermore, the analysis demonstrated variable influences of specific temperaments on boredom proneness.

Conclusions

These findings emphasize the significance of incorporating affective temperaments and boredom proneness into smoking cessation interventions. Understanding the interplay between affective temperaments and boredom proneness can guide the development of innovative and personalized cessation strategies. Further research is warranted to delve deeper into these relationships and their implications for intervention approaches.
