Agribusiness, EarlyView.ABSTRACT EU member states have exhibited varying rates of apple production growth. Technical efficiency (TE) estimation is suitable for identifying best‐practice farm performance. This study examined whether the development of the apple sector in Germany, Italy, and Poland was influenced by production efficiency, access to technology, as well as ...

Modelling between- and within-season trajectories in elite athletic performance data [PDF]
arXivAthletic performance follows a typical pattern of improvement and decline during a career. This pattern is also often observed within-seasons as athlete aims for their performance to peak at key events such as the Olympic Games or World Championships. A Bayesian hierarchical model is developed to analyse the evolution of athletic sporting performance ...

Robust seasonal cycle of Arctic sea ice area through tipping point in amplitude [PDF]
arXiv, 2012 The variation in the Arctic sea ice is dominated by the seasonal cycle with little inter-annual correlation. Though the mean sea ice area has decreased steadily in the period of satellite observations, a dramatic transition in the dynamics was initiated with the record low September ice area in 2007.

An Exploration of Modeling Approaches for Capturing Seasonal Transmission in Stochastic Epidemic Models [PDF]
arXivSeasonal variations in the incidence of infectious diseases are a well-established phenomenon, driven by factors such as climate changes, social behaviors, and ecological interactions that influence host susceptibility and transmission rates. While seasonality plays a significant role in shaping epidemiological dynamics, it is often overlooked in both ...

Who Are the Consumers of European Farmers' Markets? A Cross‐Country Analysis
Agribusiness, EarlyView.ABSTRACT With substantial growth in the number of farmers' markets (FMs) in developed countries, the number of consumers visiting FMs is also increasing. This study comparatively assesses the consumers of FMs in three European countries where FMs traditionally play a distinctive role in food supply chains.

Leveraging statistical models to improve pre-season forecasting and in-season management of a recreational fishery [PDF]
arXivEffective management of recreational fisheries requires accurate forecasting of future harvests and real-time monitoring of ongoing harvests. Traditional methods that rely on historical catch data to predict short-term harvests can be unreliable, particularly if changes in management regulations alter angler behavior.
