Objectives

The SDMPH 10-year anniversary conference created an opportunity for a researcher to present at a professional association conference to advance their research by seeking consensus of statements using Delphi methodology.

Methods

Conference attendees and SDMPH members who did not attend the conference were identified as Delphi experts. Experts rated their agreement of each statement on a 7- point linear numeric scale. Consensus amongst experts was defined as a standard deviation < = 1. Presenters submitted statements relevant to advancing their research to the authors to edit to fit Delphi statement formatting.

Statements attaining consensus were included in the final report after the first round. Those not attaining consensus moved to the second round in which experts were shown the mean response of the expert panel and their own response for opportunity to reconsider their rating for that round. If reconsideration attained consensus, these statements were included in the final report. This process repeated in a third and final round.

Results

37 Experts agreed to participate in the first round; 35 completed the second round, and 34 completed the third round; 35 statements attained consensus; 3 statements did not attain consensus.

Conclusions

A Delphi technique was used to establish expert consensus of statements submitted by the SDMPH conference presenters to guide their future education, research, and training.
The threat of abandonment: Images of the EU’s crises in post‐Maidan Ukraine
Authors: Chaban Natalia , Elgström Ole
Published: November 2024

This article further theorises and develops the notion of a threat of abandonment while trying to elucidate the applicability and usefulness of this concept in the case of Ukraine in its fight against Russia since 2014. If Ukraine perceives the European Union (EU) as weakened by multiple crises, it may translate this image into a scenario of less attention to Ukraine and its problems, and – ultimately – to a threat of abandonment, of being left alone with a powerful aggressor. Theoretically, we employ a perceptual approach. We contribute to the literature on threats of abandonment, linking it to the existence of critical expectation gaps and introducing amplifying conditions that tend to result in such gaps: a broken frame of involvement and a perceived moral injury. We also introduce a set of key factors behind a perceived risk or threat of abandonment. Empirically, we investigate how Ukrainian elites think, feel, and speak about the threat of abandonment and to what extent the two amplifying conditions were perceived to be present. Our data come from 50 in-depth interviews with Ukrainian decision makers (2016–17, C3EU Jean Monnet Network) and 53 experts’ comments published in 2022 by a Ukrainian leading social research group, Razumkov’s Centre.
Getting it right: suppression and leveraging of noise in robust decision-making
Authors: Bhalerao Rishikesh P.
Published: November 2024

Noise is a ubiquitous feature for all organisms growing in nature. Noise (defined here as stochastic variation) in the availability of nutrients, water and light profoundly impacts their growth and development. Not only is noise present as an external factor but cellular processes themselves are noisy. Therefore, it is remarkable that organisms can display robust control of growth and development despite noise. To survive, various mechanisms to suppress noise have evolved. However, it is also becoming apparent that noise is not just a nuisance that organisms must suppress but can be beneficial as low noise can facilitate the response of an organism to a sub-threshold input signal in a stochastic resonance mechanism. This review discusses mechanisms capable of noise suppression or noise leveraging that might play a significant role in robust temporal regulation of an organism’s response to their noisy environment.
Annotated checklist and community composition of introduced, cryptogenic, and native polychaetes in floating dock communities of New England, USA
Authors: Davinack Andrew A. , Carlton James T. , Pederson Judith
Published: November 2024

This study presents the first comprehensive annotated checklist of polychaetes collected from floating dock communities across New England and adjacent New York areas, emphasizing the significance of rapid biodiversity assessment surveys in understanding marine biodiversity. With 61% of the identified species classified as cryptogenic, the research highlights the complexity of marine biogeography and the challenges of distinguishing between native and non-native species. The incorporation of DNA barcoding has significantly improved species identification and revealed the presence of cryptic species complexes. The study's findings illustrate the prevalence of tubicolous families (Spionidae, Serpulidae, Sabellidae, and Terebelllidae) that are susceptible to anthropogenic dispersal mechanisms. It also addresses the challenge posed by the high proportion of cryptogenic species, calling for enhanced taxonomic and genetic analyses to resolve their origins and ecological roles. Despite the temporal variation in polychaete composition across years, the absence of distinct community assemblages suggests a level of resilience within floating dock communities. Our study advocates for the continuation and expansion of rapid assessment surveys, coupled with the integration of genetic methodologies, to provide a clearer picture of marine biodiversity.

Published: November 2024

We present multiple derivations of the Total Radiation Belt Electron Content (TRBEC), an indicator of the global number of electrons that instantaneously occupy the radiation belts. Derived from electron flux measurements, the TRBEC reduces the spatial information into a scalar quantity that concisely describes global aspects of the system. This index provides a simple, global, and long‐term assessment of the radiation belts that enables systematic analysis. In this work, we examine the TRBEC using the adiabatic invariants of which has been used in previous articles as this coordinate system removes reversible adiabatic effects. We then introduce a new expression to compute the TRBEC using the non‐adiabatic coordinates of , relevant in the contexts of energetic electron precipitation, chorus, and hiss scattering where adiabatic invariant quantities are no longer conserved. From both expressions of the TRBEC we demonstrate that an erroneous factor of that appeared in previous works using the adiabatic derivation led to an overestimate of the reported electron populations. In addition, we quantify electron loss in the outer radiation belt via a case study using the Van Allen Probes data over a 20‐day period from March 2013 specifying particle populations both in terms of the aforementioned adiabatic and non‐adiabatic variables. The total number of electrons in the outer radiation belt reached upwards of electrons at the peak of the storm, a rest mass of roughly 10 g.
Different Behavior of Density Perturbations Between Dayside and Nightside in the Martian Thermosphere and the Ionosphere Associated With Atmospheric Gravity Waves

Published: November 2024

To investigate the excitation mechanism of ionospheric perturbations on Mars by the Neutral Gas and Ion Mass Spectrometer (NGIMS) onboard Mars Atmosphere and Volatile EvolutioN (MAVEN), we categorize ionospheric perturbations into three cases: (a) the ion‐neutral coupling cases where ion and neutral perturbations are well coupled, (b) the ion‐specific cases where ion perturbations move independently from neutrals, and (c) the coronal mass ejection cases associated with solar wind extreme events. A representative number of cases from total profiles are compared with a numerical model to determine the fraction that can be explained by an atmospheric gravity waves (GW). The neutral perturbations on the dayside at 170–190 km altitudes are in excellent agreement with the GW. Whereas, contrary to previous thoughts, neutral perturbations are not necessarily explained by the GW especially on the nightside at 190–210 km. Ion perturbations on the dayside at 170–190 km also show a good agreement with the GW. The agreement becomes extremely low on the nightside at 190–210 km, reaching the limit of strong ion‐neutral coupling around 190 km. Further investigation found that the behavior of the ion perturbations explicitly depends on the dayside and nightside. Its dominant driver potentially differs clearly between dayside and nightside. Statistics of relative perturbations demonstrate a clear effect associated with species scale height in neutrals. Whereas, the correlation between ions and neutrals breaks down at high solar zenith angle near southern dusk. We see currently unexplained behavior that cannot be fully interpreted by GW both at night and near southern dusk.
Tuning Earth System Models Without Integrating to Statistical Equilibrium
Authors: DelSole Timothy , Tippett Michael K.
Published: November 2024

This paper proposes algorithms for estimating parameters in Earth System Models (ESMs), specifically focusing on simulations that have not yet achieved statistical equilibrium and display climate drift. The basic idea is to treat ESM time series as outputs of an autoregressive process, with parameters that depend on those of the ESM. The maximum likelihood estimate of the parameters and the associated uncertainties are derived. This method requires solving a nonlinear system of equations and often results in unsatisfactory parameter estimates, especially in short simulations. This paper explores a strategy for overcoming this limitation by dividing the estimation process into two linear phases. This algorithm is applied to estimate parameters in the convection scheme of the Community Earth System Model version 2 (CESM2). The modified algorithm can produce accurate estimates from perturbation runs as short as 2 years, including those exhibiting climate drift. Despite accounting for climate drift, the accuracy of these estimates is comparable to that of algorithms that do not. While these initial results are not optimal, the autoregressive approach presented here remains a promising strategy for model tuning since it explicitly accounts for climate drift in a rigorous statistical framework. The current performance issues are believed to be technical in nature and potentially solvable through further investigation.
Microbial melatonin metabolism in the human intestine as a therapeutic target for dysbiosis and rhythm disorders
Authors: Zimmermann Petra , Kurth Salome , Pugin Benoit , Bokulich Nicholas A.
Published: November 2024

Melatonin (MT) (N-acetyl-5-methoxytryptamine) is an indoleamine recognized primarily for its crucial role in regulating sleep through circadian rhythm modulation in humans and animals. Beyond its association with the pineal gland, it is synthesized in various tissues, functioning as a hormone, tissue factor, autocoid, paracoid, and antioxidant, impacting multiple organ systems, including the gut-brain axis. However, the mechanisms of extra-pineal MT production and its role in microbiota-host interactions remain less understood. This review provides a comprehensive overview of MT, including its production, actions sites, metabolic pathways, and implications for human health. The gastrointestinal tract is highlighted as an additional source of MT, with an examination of its effects on the intestinal microbiota. This review explores whether the microbiota contributes to MT in the intestine, its relationship to food intake, and the implications for human health. Due to its impacts on the intestinal microbiota, MT may be a valuable therapeutic agent for various dysbiosis-associated conditions. Moreover, due to its influence on intestinal MT levels, the microbiota may be a possible therapeutic target for treating health disorders related to circadian rhythm dysregulation.

The role of protein O-GlcNAcylation in diabetic cardiomyopathy
Authors: Chatham John C. , Wende Adam R.
Published: November 2024

It is well established that diabetes markedly increases the risk of multiple types of heart disease including heart failure. However, despite substantial improvements in the treatment of heart failure in recent decades the relative increased risk associated with diabetes remains unchanged. There is increasing appreciation of the importance of the post translational modification by O-linked-N-acetylglucosamine (O-GlcNAc) of serine and threonine residues on proteins in regulating cardiomyocyte function and mediating stress responses. In response to diabetes there is a sustained increase in cardiac O-GlcNAc levels, which has been attributed to many of the adverse effects of diabetes on the heart. Here we provide an overview of potential mechanisms by which increased cardiac O-GlcNAcylation contributes to the adverse effects on the heart and highlight some of the key gaps in our knowledge.

Published: November 2024

The Central Bureau of Statistics (2013) corn production in Indonesia in 2012 amounted to 19.37 million tons, but Indonesia still imported 3.2 million tons of corn from abroad. The cause of the decline in corn production is due to climate change and nutrient-deficient (dry) land conditions. Rhizobaktery biological fertilizers have the ability to increase plant drought tolerance, increase crop production and produce growth hormone IAA. The aim of the study was to determine the interaction between the types of corn plant varieties and the doses of liquid biofertilizers, the effect of the types of varieties and the effects of liquid biofertilizer doses on the growth and yield of corn plants. Methods include bacterial propagation, biofertilizer production, cultivation according to recommendations and statistical analysis of Split Plot Design with 5% HSD follow-up test. The results indicated interactions between treatments of corn varieties and liquid biofertilizer doses on dry land. Corn variety had a significant effect on the Bisi 99 treatment on the growth and yield of corn plants. Liquid biological fertilizer had a significant effect, the 50 ml dose treatment was the best for corn yields, while the 100 ml dose treatment was the best for corn growth.

Published: November 2024

This study examines the effects of varying LED durations and the seedling’s dark phase on microgreen mung bean growth rate, yield, and quality. Conducted in December 2023 at the Laboratory of Microgreen Cultivation, Jl. Joyo Agung, Malang, at an elevation of approximately 625 meters, the study utilized a box experiment with a split-plot design. The primary variable was the length of the LED dark phase (0, 12, and 18 hours), while the subplot focused on the early seedling dark phase treatment (two 24-hour dark phases and no dark phase). Analysis of variance showed no significant interaction between LED exposure time and blackout treatment, except for plant texture. The best plant texture (6.10 mm/s) was achieved with 18 hours of exposure and an early-stage dark period. LED light exposure influenced the total fresh weight, total dry weight, and total soluble solids of the plants. The 12-hour exposure produced the highest total fresh weight (85.15 g), while the 18-hour exposure resulted in the highest total dry weight (6.28 g), crown dry weight (5.70 g), and total soluble solids at 4 and 6 days after sowing (8.80oBrix and 8.27oBrix, respectively).

Imperata cylindrica root as PGPR pressing the pathogen phytophthora infestant the cause of wilt disease in potato plant (Solanum tuberosum L.)
Authors: Roeswitawati Dyah , Sutarman Sutarman , Indratmi Dian
Published: November 2024

Potatoes (Solanum tuberosum L.) are a staple food worldwide, in addition to wheat, corn, rice, and wheat. In Indonesia, the potato commodity has received priority for development because it is a source of non-rice carbohydrates and has the potential for food diversification programs. Since 2016, Indonesian potato production has decreased due to attacks by the fungus Phytophthora infestans. Potato plants attacked by Phytophthora infestans show symptoms in small wet spots coloured pale green to dark green. So far, potato farmers have only relied on chemical pesticides to control these pathogens. The research aimed to test the potential of the Imperata cylindrica root to suppress the Phytophthora infestans pathogen that causes potato disease (Solanum tuberosum L.). The results show that the Imperata cylindrica root as PGPR can reduce the intensity of Phytophthora infestans attacks on potato. This is not significantly different compared to factory-made PGPR (Biopharma) but is significantly different compared to PGPR, which comes from the roots of bamboo plants. It is suspected that in the rhizosphere of the plant there are bacteria that release secondary metabolites so that they can suppress the Phythtopthora infestant pathogen through the process of antibiosis.

Published: November 2024

Lamtoro leaves can be a protein source for poultry feed, but the cells protect the protein. Cellulolytic fermentation is needed to degrade the cell walls and liberate proteins in cells. The study aimed to determine the effect of using Trichoderma Koningiopsis in fermentation on changes in nutrient content and weight of lamtoro leaf biomass. The study used a completely randomized design with a one-way pattern. The treatments consisted of fermentation duration: 0, 2, 4, and 6 days. Each treatment used three replications. The variables observed included temperature, pH, soluble protein content, cellulose, and biomass weight. The results showed that the fermentation of lamtoro leaves using Trichoderma koningiopsis significantly affected all observed variables. Fermentation temperature, soluble protein, and cellulose content initially increased (2 days: temperature; 4 days: dissolved protein and cellulose) and then decreased as fermentation continued.Meanwhile, pH decreased in 2 days of fermentation, and the value remained constant for 4 and 6 days. Biomass weight decreased by 18% in 6 days of fermentation. Trichoderma koningiopsis significantly affects temperature, pH, soluble protein content, crude fiber, cellulose, and Lamtoro leaf biomass weight. Six-day fermentation is the best fermentation.

Published: November 2024

The cultivation of ornamental fish has not yet reached an adequate level to consistently produce high color quality, which is a key determinant of the fish’s market value. This study aims to investigate the Effect of Spirulina platensis, which is believed to contain carotenoids that can enhance the color of freshwater ornamental fish, specifically Betta splendens. A quantitative approach using a Completely Randomized Design (CRD) experimental model was employed to test the hypothesis, with the results analyzed statistically and described in detail. The study found that treatment 2, involving a 1% concentration of Spirulina powder in artificial feed, resulted in the best increase in color intensity, as indicated by a more yellow and darker hue compared to the control, P3, and P4 treatments. The study suggests that future research should include a larger sample size to achieve optimal results.

The high demand for koi fish must be supported by an adequate supply of fry, both in quantity and quality. High-quality fry comes from superior broodstock. This study aimed to evaluate the quantity, type, and quality of fry produced by crossbreeding local and imported broodstock. A descriptive quantitative method was used, with natural spawning at a ratio of 1:3 (female), involving Shiro F1, local Shiro, local Showa, and imported Ginrin Shiro. Results showed a fecundity of 103,800 eggs, with fertilization, hatching, and survival rates of 84%, 93%, and 74.7%, respectively. The first selection yielded 79% high-quality fry, while the second selection produced 10% high-quality fry. Showa fry dominated the second selection, comprising 84% of that batch and 9.2% of the total fry, while Shiro fry made up 16% of the second selection and 1.7% of the overall fry. The highest daily growth rate occurred in the first week (4.6%/day), while the lowest was in the second week (2.08%/day). The highest specific growth rate was also in the first week (36.43%/day), with the lowest in the fourth week (5.61%/day). Water quality remained suitable for koi fry survival throughout the study.

Published: November 2024

This research was carried out to determine the chemical composition, antioxidant, and anti-diabetic potential of ethyl acetate extract of kitolod fruit (Isotoma longiflora (L) Presl). The design of this research was carried out descriptively. To obtain bioactive compound components, the Kitolod fruits were dried at a temperature of 50°C and then ground into powder until they passed through an 80 mesh sieve. Extraction was carried out using the maceration method at 30°C for 48 hours with an ethyl acetate solvent. Ethyl acetate extracts had been fractioned with n-Hexan and identified through LC-MS examination. The dominant chemical composition of ethyl acetate extract was sesquiterpene (66.74%), followed by flavonoids (18.11%). Antioxidant potential was evaluated through DPPH free radical scavenging activity and inhibition of α-amylase and αglucosidase enzyme activity. Ethyl acetate extract showed moderate levels of antioxidant activity. The inhibitory activity of α-amylase enzyme is lower than quercetin as a positive standard, but the inhibitory activity of αglucosidase enzyme is extreme with an IC50 value of 47.33 ±1.40 μgmL-1. These results suggest that ethyl acetate extracts from the fruit have the potential for antidiabetic-based natural products and antioxidant agents.

Published: November 2024

Land management in paddy farming can be done traditionally with animal power or modernly with tractors. Tractors facilitate land management but are not accessible to all farmers. This study investigates paddy farmers' motivation to use animal power and tractors, using the ERG motivation theory (Existence, Growth, and Relatedness). A descriptive, quantitative approach was applied to 60 farmers. Findings show that motivation to use tractors is very high in the Existence category, and moderate in Relatedness and Growth categories.

Food stands as the cornerstone of human existence, serving as the quintessential necessity for sustaining life, especially for those people who living outside as migrant worker. This research aims to explore the food and non-food consumption patterns of Agriculture Migrant Household. This study was conducted on August 2023. The sampling method was purposive sampling in Binangun and Nusawungu sub-districts, Cilacap District, Central Java Province. Considering that according to BP2MI 2023 data, Cilacap Regency is the third-largest contributor of Indonesian migrant workers and has the highest number of PMI (Indonesian Migrant Workers) in Central Java. The average expenditure for migrant households is higher (IDR 13,254,783) than non-migrant households (IDR 12,348,120). Migrant households show significantly higher expenditures on food and non-food items, primarily driven by remittances that enhance their economic stability, allowing for better health and education investments. The migrant households benefit economically from remittances, non-migrant households display a more constrained expenditure pattern, often aligning closely with their limited income levels. This disparity underscores the critical role that migration plays in shaping economic behaviours and consumption decisions within communities.

This research seeks to ascertain the kinetic parameters of VCO degradation based on the formation of peroxide and free fatty acids and to evaluate the shelf life of bromelain-extracted VCO at various temperatures. The kinetic parameters and shelf life of VCO were determined by measuring the value of peroxides and free fatty acids (FFA) concentration at temperatures of 50 ºC to 200 ºC. The heating was performed in a 1 L conical flask immersed in the paraffin bath. Samples were collected for each temperature at 0 to 60 minutes. The rate constant of peroxide and FFA formation was determined by regression analysis using Microsoft Excel, based on the plot of sampling time and value of peroxide and FFA concentration. The rate constant of peroxide formation escalated from 0.0114 to 0.1419 mEq Kg-1 min-1 when the VCO was heated at 50 ºC to 200 ºC. Meanwhile, the rate constant of FFA formation rose from 0.0188 to 0.0393 % min-1 when subjected to heating at 50 ºC to 200 ºC. Based on the shelf-life prediction established by Indonesian National Standards or the Asian and Pacific Coconut Community, the shelf-life of bromelain- extracted VCO varies from 10 to 3 hours at temperatures ranging from 2 ºC to 50 ºC. It was determined that elevating the temperature reduced the shelf-life of bromelain-extracted VCO. These findings suggest that temperature is crucial for the stability of bromelain-extracted VCO.
