TitleDistributed Ledger Provenance for Artisanal Fisheries Catch Documentation in Export Supply Chains

Abstract

European import rules increasingly require demonstrable chain of custody from landing site to processor. We pilot a permissioned ledger where fishers record GPS-stamped landings, middlemen append cold-chain temperature hashes, and inspectors anchor PDF certificates without exposing buyer prices on-chain. Pilot lanes reduce paperwork reconciliation time during audits while highlighting connectivity gaps at remote ice plants that still rely on paper ledgers.

TitleMorphometric CT Indices for Estimating Body Condition in Rehabilitated Raptors Prior to Release
Paper IDzC3nW
Keywordsraptor rehabilitation; computed tomography; body condition; morphometrics; wildlife medicine
Abstract

Wildlife clinics need objective release criteria beyond subjective muscle scoring. Low-dose CT of pectoral regions in common buzzards yields pectoral thickness and keeled-sternum angles that correlate with post-mortem fat indices in training carcasses. Prospective releases where CT indices exceed species-specific thresholds show lower re-admission rates for starvation within six months than releases approved on mass alone.

TitleStable Isotope Mixing Models for Partitioning Diet of Generalist Shorebirds Along Stopover Mudflats
Paper IDvM8gR
Keywordsstable isotopes; shorebird; mixing model; stopover ecology; diet reconstruction
Abstract

Generalists complicate attribution when prey isotopes overlap across biofilm, polychaetes, and small bivalves. We apply Bayesian mixing with concentration dependence and lipid normalization on red blood cells collected during northbound migration. Posterior source contributions shift toward biofilm when mud surface chlorophyll spikes, reconciling earlier bulk-tissue inferences that overstated polychaete reliance during calm weather windows.

TitleAgent-Based Simulation of Vaccine Hesitancy Diffusion on Mixed Online–Offline Social Networks
Paper IDpX5cH
Keywordsagent-based model; vaccine hesitancy; social network; public health communication; simulation
Abstract

Policy debates increasingly focus on how misinformation cascades between messaging apps and community gatherings. We couple an opinion dynamics model with empirically sampled degree distributions from household surveys and synthetic online edges. Scenarios where trusted local health workers broadcast corrective summaries dampen peak hesitant fractions more than generic national campaigns, especially when offline tie strength is heavy-tailed.

TitleLaser-Induced Breakdown Spectroscopy for Rapid Screening of Trace Metals in Hydroponic Nutrient Solutions
Paper IDkF7sN
KeywordsLIBS; hydroponics; trace metals; nutrient management; spectroscopy
Abstract

Greenhouse operators often rely on slow laboratory ICP assays when recirculating solutions drift. A compact LIBS bench with partial least-squares calibration tracks iron, manganese, and zinc across dilution series mimicking commercial blends. Field trials on tomato lines show early warning of micronutrient depletion one week before leaf chlorosis appears, though calcium remains below quantification without matrix-matched standards.

TitleNetwork Meta-Analysis of School-Based Interventions for Adolescent Sleep Duration

Abstract

Competing trial designs report heterogeneous effects on weekday sleep. We synthesize randomized studies of delayed start times, classroom education modules, and evening screen curfews within a Bayesian network framework. Combined education plus parental messaging ranks highest for increasing actigraphy-measured sleep minutes, whereas start-time shifts alone show wider credible intervals when academic pressure covariates are sparse.

TitleEpigenetic Clocks in Long-Lived Seabirds: Comparing Tissue-Specific Methylation Age Gaps
Paper IDhT9mQ

Abstract

Demographic models for threatened colonies need proxies for physiological senescence when banding histories are incomplete. We fit elastic-net clocks trained on blood and feather methylomes from two procellariiform species with contrasting foraging ranges. Blood-derived ages track known hatch years more closely than feather clocks, yet feather estimates diverge predictably after prolonged fasting bouts, suggesting tissue choice matters for stress biomonitoring.

Abstract

Volunteer depth boards provide irregular measurements that standard interpolation treats as independent. We embed melt and compaction processes in a latent daily SWE layer informed by temperature and precipitation covariates. Hold-out experiments on mountain catchments with reference snow pillows show reduced bias during midwinter rain-on-snow events compared with inverse-distance weighting of raw depths.

TitleThe Motivation, Supported both by Psychology and Economics

Abstract

This paper aims to reunite (not necessarily to reconcile) psychology and economics through a contemporary perspective on workplace motivation. This approach differs from the classic presentations by Kahneman and Tversky, by adapting the discussion to current organizational and economic conditions.

The study draws on academic literature, good practices in the field, and expert opinions from both economics and psychology. As a qualitative research, it also incorporates insights from questions and questionnaires involving students, MAs, bachelors (Alumni system). Furthermore, from a theoretical perspective and based on worldwide sources of information, the analysis indicates that Self-Determination Theory (SDT) represents one of the most prominent and widely applied frameworks for understanding motivation today.

The results of the analysis, corroborated by the answers and opinions received, lead to the conclusion that, nowadays workplace motivation reflects a combination of intrinsic and extrinsic motivation. Up to a certain turning point, one form of motivation becomes dominant, after which the other takes precedence, and vice versa. This dynamic interaction creates a "win-win" scenario, fostering personal satisfaction at work while supporting organizational profitability.
