After graduating from the China Academy of Arts(Department of Oil Painting)in Hangzhou in 1995,Yang Fudong(1971)moved to Shanghai to work as a graphic designer.Inspired by his daily job in Pudong,he started producing photographic series that closely resembled the advertising campaigns he worked on.Glossy images of stylish young people or dishevelled white collars in highly saturated colours,defined“intellectuals”in cryptic accompanying captions.Conversely,his body of work in black and white,almost entirely shot on 35mm film,portrays a suspended reality out of the historical time:a ghostly dimension akin to a drowsy vigil,a uchronia,an“estranged paradise”-to borrow the title of his earliest film set in Hangzhou.But it is Shanghai’s elusiveness and material relationship with the past that has contributed the most to form Yang’s trademark imagery and aesthetic.What he conjures up in his still and moving images,is a dimension with a distinctive oneiric quality,an“in-between”universe where all the circumstances are justified and have an inner logic,just like in dreams,or just like in the China of his childhood.The research of Yang Fudong is somewhat unique in the universe of contemporary Chinese art and sets him apart from a plethora of artists that have used the video in a much more“didactic”and quotational way.I will illustrate some specific aspects of his black and white body of work,trying to show how a certain self-orientalist trait can be interpreted as strategy to regain narrative agency and bring to the surface a series of removed instances:the main of which being,in my opinion,the fate of Shanghai’s(perhaps of China's Mainland in its ungraspable entirety?)modernity. 展开更多

In this conceptual paper,the author develops and presents a strategic decision-making framework that applies game theory to evaluate smart and natural farming approaches in India.In the face of increasing pressures from climate change,resource scarcity,and evolving socio-economic landscapes,agriculture must adapt to the challenges of a volatile,uncertain,complex,and ambiguous(VUCA)world.When integrated with the Provision of Urban Amenities in Rural Areas(PURA)framework,VUCA offers a dynamic system perspective that contextualizes uncertainty and institutional capacity in farming systems.This study applies a modified Spence signaling model to capture how farmers-categorized as smart or natural versus conventional-choose to signal their sustainability credentials in an environment of asymmetric information.Using a combination of payoff matrix modelling,Bayesian belief updating,and evolutionary game simulations,the paper identifies strategic equilibria under varying levels of policy support,consumer trust,and signal cost.Farmers’decisions to adopt smart technologies or organic certifications are modelled as costly but credible signals of quality.These signals are then interpreted by receivers such as consumers,investors,or policymakers,who in turn adjust their support or market preferences.The analysis reveals conditions under which separating,pooling,and semi-separating equilibria emerge,and how these outcomes impact farmer behaviour and systemic sustainability.Case studies from Indian states such as Andhra Pradesh,Karnataka,and Punjab demonstrate how real-world farming programs mirror theoretical outcomes under different signalling strategies.The study also presents a robust methodological structure,combining conceptual modelling with policy simulation and validation through comparative cases.By integrating environmental,technological,and institutional perspectives,this paper contributes a hybrid strategic framework aligned with India’s Green Revolution 2.0 goals.It offers practical recommendations for policy design,infrastructure planning,and market mechanisms that support the scaling of sustainable agricultural practices through credible signalling and game-theoretic insights. 展开更多

Plant height is an important trait that affects the crop yield and overall productivity.The Green Revolution,which began in the 1960s,brought about a remarkable surge in grain production,largely credited to the introduction of new wheat(Triticum aestivum)and rice(Oryza sativa)varieties,specifically the dwarf variants.Short plants offer several advantages,including denser planting,resistance to lodging,and easier application of fertilizers or fungicides(Stokstad,2023). 展开更多
