The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee

Agribusiness, EarlyView.
ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

Determinants of Knowledge and Usage of Generative Artificial Intelligence in Agricultural Extension: Evidence From Tennessee Extension Personnel

Agribusiness, EarlyView.
ABSTRACT This paper examines the determinants of generative AI (GenAI) knowledge and usage among agricultural extension professionals. Drawing on survey data from agricultural extension personnel in Tennessee, we employ regression analyses and latent Dirichlet allocation (LDA) for topic modeling of open‐ended responses to study the knowledge and usage ...

Accelerated destructive degradation test based on skew-normal measurement error model

, 2014
碩士加速破壞衰變試驗，其量測過程中，需破壞測試樣本，以便量測到產品的品質特徵值，並配合提高環境應力，以加速產品衰變，進而有效地推估產品的壽命資訊。Tsai et al. (2013) 建構一量測誤差服從常態分配的非線性 ADDT 衰變模型。然而，當量測誤差為非對稱的分配時，此時使用偏常態分配來描述較為合適。因此，本文以聚合物材料為動機例子，首先建構一偏常態 ADDT 衰變模型，並探討其壽命資訊，其結果顯示使用本文所建構的衰變模型，來推估產品壽命較為精確。接下來，模擬一組偏常態 ADDT 衰變資料 ...

Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

Agribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

A new class of Skew-Normal-Cauchy Distribution

In this paper we study a new class of skew-Cauchy distributions inspired on the family extended two-piece skew normal distribution. The new family of distributions encompasses three well known families of distributions, the normal, the two-piece skew ...
