Gains And Losses

AbstractIndividual differences in perception are widespread. Considering inter-individual variability, synesthetes experience stable additional sensations; schizophrenia patients suffer perceptual deficits in e.g. perceptual organization (alongside hallucinations and delusions). Is there a unifying principle explaining inter-individual variability in perception? There is good reason to believe perceptual experience results from inferential processes whereby sensory evidence is weighted by prior knowledge about the world. Different perceptual phenotypes may result from different precision weighting of sensory evidence and prior knowledge. We tested this hypothesis by comparing visibility thresholds in a perceptual hysteresis task across medicated schizophrenia patients, synesthetes, and controls. Participants rated the subjective visibility of stimuli embedded in noise while we parametrically manipulated the availability of sensory evidence. Additionally, precise long-term priors in synesthetes were leveraged by presenting either synesthesia-inducing or neutral stimuli. Schizophrenia patients showed increased visibility thresholds, consistent with overreliance on sensory evidence. In contrast, synesthetes exhibited lowered thresholds exclusively for synesthesia-inducing stimuli suggesting high-precision long-term priors. Additionally, in both synesthetes and schizophrenia patients explicit, short-term priors – introduced during the hysteresis experiment – lowered thresholds but did not normalize perception. Our results imply that distinct perceptual phenotypes might result from differences in the precision afforded to prior beliefs and sensory evidence, respectively.

Abstract Individual differences in perception are widespread. Considering inter-individual variability, synesthetes experience stable additional sensations; schizophrenia patients suffer perceptual deficits in, eg, perceptual organization (alongside hallucinations and delusions). Is there a unifying principle explaining inter-individual variability in perception? There is good reason to believe perceptual experience results from inferential processes whereby sensory evidence is weighted by prior knowledge about the world. Perceptual variability may result from different precision weighting of sensory evidence and prior knowledge. We tested this hypothesis by comparing visibility thresholds in a perceptual hysteresis task across medicated schizophrenia patients (N = 20), synesthetes (N = 20), and controls (N = 26). Participants rated the subjective visibility of stimuli embedded in noise while we parametrically manipulated the availability of sensory evidence. Additionally, precise long-term priors in synesthetes were leveraged by presenting either synesthesia-inducing or neutral stimuli. Schizophrenia patients showed increased visibility thresholds, consistent with overreliance on sensory evidence.

Abstract Electric power sectors around the world have changed dramatically in the last 25 years as a result of sector liberalization policies. Many electricity sectors are now pursuing deep decarbonization goals which will entail replacing dispatchable fossil generation primarily with intermittent renewable generation (wind and solar) over the next 20–30 years. This transition creates new challenges for both short-term wholesale market design and investment incentives consistent with achieving both decarbonization commitments and security of supply criteria. Thinking broadly about the options for institutional change from a Williamsonian perspective – thinking like Williamson – provides a useful framework for examining institutional adaptation. Hybrid markets that combine ‘competition for the market’ that relies on competitive procurement for long-term purchased power agreements with wind, solar, and storage developers, ideally in a technology neutral fashion, and ‘competition in the market’ that relies on short-term markets designed to produce efficient and reliable operations of intermittent generation and storage, is identified as a promising direction for institutional adaptation. Many auction, contract, and market integration issues remain to be resolved.

ABSTRACTThe recent involvement of China in sub-Saharan Africa is challenging and changing the world geostrategic scene. In the article, we analyse the agreements between the Congolese government and a group of Chinese state-owned enterprises. A number of public infrastructure works will be financed with Chinese loans. To guarantee reimbursement, a Congolese/Chinese joint venture will be created to extract and sell copper, cobalt and gold. These are the biggest trade/investment agreements that China has so far signed in Africa. This article seeks to contribute to the discussion regarding the agreement's impact on internal development in Congo. Does it create a ‘win-win’ situation for all, or is it an unequal exchange? We outline the internal and international debates and analyse several noteworthy characteristics of the agreements. In conclusion, we present a balanced view on the likely impact on Congo's short-term and long-term development.

New Structural Economics

The world economy needs a growth-lifting strategy, and infrastructure financing seems to hold the key. Based on the New Structural Economics (Lin, 2010; 2012) we discuss the heterogeneity of capital focusing on the long-term versus short-term orientation (STO). Traditional neoliberalism assumes that capital is homogenous, complete capital account liberalization is “beneficial”.However, previous studies have found evidence of long-term orientation (LTO) in the culture of many Asian economies (Hofstede, 1991). In this exploratory paper, we suggest that the LTO can be considered a special endowment which, under certain circumstances, can be developed into a comparative advantage (CA) in patient capital. If these countries can turn their latent CA into arevealed CA in patient capital, and develop the ability to “package” profitable and non-profitable projects in meaningful ways, they would have a “revealed” competitive advantage in infrastructure financing. The ability to “package” public infrastructure and private services is one of the key institutional factors for success in overseas cooperation.

Global Growth

In 2012, Vietnam?s economy faced great challenges. The world economy experienced more difficulties and complicated upheavals. International trade fell drastically while global growth rate was lower than predicted target, which affected badly the Vietnamese economy because of its full integration into the world economy and large openness. In this context, principal targets set for 2013 are macroeconomic stability, lower inflation rate, higher growth rate, three strategic breakthroughs associated with restructuring of the economy, and a new economic growth model. This paper analyzes obstacles to Vietnam?s economic growth, and offers short-term solutions to bottlenecks and long-term ones to the economic restructuring.

This chapter considers a variety of methods of treating Germany. The main objective of the United Nations in the treatment of Germany is to prevent it from ever again becoming a threat to the security of the world. The problem of securing this objective could be approached through destruction of Germany's industrial potential, destruction of Germany as a political entity, and removal from German society of the causes of aggression. The chapter shows that the first two solutions should be deferred until it is clear that the third alternative proves unworkable. In order to eliminate the causes of aggressiveness in German society, temporary and long-term disabilities should be imposed upon Germany. The chapter also examines the causes of German aggression, the United States' policy toward Germany, short-term measures during the period of military government, conditional measures during the probationary period, and permanent impositions upon Germany.

This chapter discusses the emerging models of knowledge cities in many countries of the world and the potential challenges posed by them for the existing as well as the future academic institutions of higher education (universities) in those countries in particular and in the in world in general. Specifically, this chapter is dedicated to the study of various issues and themes that concern the evolving knowledge cities such as the long-term and short-term objectives behind the establishment of knowledge cities and their potential benefits (i.e., social, economic, financial, environmental, and knowledge) for their societies. The chapter concludes that the development of knowledge cities are beneficial for all stakeholders including the academic institutions of higher education that directly or indirectly associated with such programs.

This chapter takes a deeper look at the culture of infidelity that pervades the world of professional sports, why wives share a universal fear that their husbands will be unfaithful, and how they are affected by the possibility or actuality that their husbands will engage in sexual or emotional relationships with other women. Three patterns of infidelity are identified in the context of the sport marriage: the one-time encounter, the short-term affair, and the long-term affair. The concept of suspicion work is introduced to examine how wives try to manage the fear that their husbands may succumb to temptation and to specify how denial can be part of this process. The chapter discusses re-entry routines and communication methods some couples use when husbands return from travel, and the boundaries of fidelity and forgiveness wives establish as they attempt to cope with the realities of their husbands’ lives on the road.

Short Time

Statistical models based on the asymptotic limit theorems of control and information theories allow formal examination of the essential differences between short-time “tactical” confrontations and a long-term “strategic” conflict dominated by evolutionary process. The world of extended coevolutionary conflict is not the world of sequential “muddling through.” The existential strategic challenge is to take cognitive control of a long-term dynamic in which one may, in fact, be “losing” most short-term confrontations. Winning individual battles can be a relatively direct, if not simple or easy, matter of sufficient local resources, training, and resolve. Winning extended conflicts is not direct, and requires management of subtle coevolutionary phenomena subject to a dismaying punctuated equilibrium more familiar from evolutionary theory than military doctrine. Directed evolution has given us the agricultural base needed for large-scale human organization. Directed coevolution of the inevitable conflicts between the various segments of that organization may be needed for its long-term persistence.
