This article introduces the special section on the making and remaking of agro-industries in Africa. It examines what the contributions tell us about how agro-industries work, but also why national industries work the way they do, how they came to be that way and what factors and forces drive or hinder their dynamism. 相似文献

This paper raises an old question and proposes a new answer. The question is, “Must public goods be produced by governments?” The consensus answer is “Yes,” on the grounds that transaction costs related to group size prevent all potential consumers of a public good from entering into voluntary arrangements to produce efficient levels of that good. Government intervention thus is required to achieve efficiency. Yet many obvious examples of public goods are not financed or even subsidized by government. Conspicuous examples of this phenomenon include the development of important innovations in technique in fields such as music (Bach and Beethoven), literature (Defoe, Dickens and Shakespeare, not excepting Homer or Adam Smith), and the visual arts (Cezanne), not to mention many crucial scientific discoveries. Indeed, the obvious public-good aspects of scientific knowledge induced many private societies to offer prizes for particular innovations. Two questions are raised by the private, voluntary provision of nonrival outputs or inputs: (1) what conditions contribute to this phenomenon, and (2) can voluntary provision come “close” to efficient provision? We suggest in this paper that, under certain conditions, the gains from many public goods whose benefits reach nationwide populations are largely realized at group sizes far smaller than even county or municipal jurisdictions. 相似文献

This article examines three contemporary organizational theories as they relate to organization structure. The three approaches selected are: social systems delimitation, organization learning, and organizational theory as metaphors. Each view represents a different approach to issues concerning the direction of organization theory and design. It will be argued that, in many respects, the future development of organizational theory will, to a large extent, build upon these approaches and the issues they pose for organization design. 相似文献

The present article outlines the role of personal, social, and cultural identity in religiously and ethnically motivated terrorism. It is proposed that terrorism represents the confluence of a cultural identity strongly based in collectivism and in fundamentalist adherence to religious or cultural principles, a social identity based in sharp contrasts between one's own group and groups perceived as threats, and a foreclosed and authoritarian sense of personal identity or, less often, a diffused and aimless personal identity. Examples from religious-extremist and ethnic conflicts in which terrorism has been employed are used to illustrate the tenets advanced here. Recommendations for addressing and preventing the threat of terrorism are discussed. 相似文献

Scotland seems to be a counter-example to general theories of the relationship between language and national identity or nationalism. These theories point to three components in the ideology of language and nation—that being able to speak the national language is necessary for full national membership, that the national language is a core part of the nation's culture, and that the future of national political autonomy and the future of the national language are connected with each other. In Scotland, it has appeared that language is not central to national membership or culture, and language campaigning has not been central to the political campaigns for autonomy. The article presents new evidence, from the 2012 Scottish Social Attitudes Survey, which questions these beliefs about the relationship between language and national identity or nationalism in Scotland. 相似文献

How do policies in international organizations reflect the preferences of powerful institutional stakeholders? Using an underutilized data set on the conditions associated with World Bank loans, we find that borrower countries that vote with the United States at the United Nations are required to enact fewer domestic policy reforms, and on fewer and softer issue areas. Though U.S. preferences permeate World Bank decision making, we do not find evidence that borrower countries trade favors in exchange for active U.S. intervention on their behalf. Instead, we propose that U.S. influence operates indirectly when World Bank staff—consciously or unconsciously—design programs that are compatible with U.S. preferences. Our study provides novel evidence of World Bank conditionality and shows that politicized policies can result even from autonomous bureaucracies. 相似文献

For many low‐income Medicare beneficiaries, Medicaid provides important supplemental insurance that covers out‐of‐pocket costs and additional benefits. We examine whether Medicaid participation by low‐income adults age 65 and up increased as a result of Medicaid expansions to working‐age adults under the Affordable Care Act (ACA). Previous literature documents so‐called “welcome mat” effects in other populations but has not explicitly studied older persons dually eligible for Medicare and Medicaid. We extend this literature by estimating models of Medicaid participation among persons age 65 and up using American Community Survey data from 2010 to 2017 and state variation in ACA Medicaid expansions. We find that Medicaid expansions to working‐age adults increased Medicaid participation among low‐income older adults by 1.8 percentage points (4.4 percent). We also find evidence of an “on‐ramp” effect; that is, low‐income Medicare beneficiaries residing in expansion states who were young enough to gain coverage under the 2014 ACA Medicaid expansions before aging into Medicare were 4 percentage points (9.5 percent) more likely to have dual Medicaid coverage relative to similar individuals who either turned 65 before the 2014 expansions or resided in non‐expansion states. This on‐ramp effect is an important mechanism behind welcome mat effects among some older adults. 相似文献

This article examines relationships between local drug policy (as represented by prosecutor-reported case outcomes for first-offender juvenile marijuana possession cases) and youth self-reported marijuana use, perceived risk, and disapproval. Interviews with prosecutors and surveys of 8th-, 10th-, and 12th-grade students in the United States were conducted in 2000. Analyses include data from 97 prosecutors and students from 127 schools in 40 states. Results indicate significant relationships between local drug policy and youth marijuana use and attitudes. In general, more-severe dispositions are associated with less marijuana use, higher disapproval rates, and increased perceptions of great risk. Associations primarily appear to be specific to marijuana-related outcomes. Results are discussed within the framework of both deterrence and broader social norms regarding substance use. 相似文献

We examined whether individuals’ ability to detect deception remained stable over time. In two sessions, held one week apart,
university students viewed video clips of individuals and attempted to differentiate between the lie-tellers and truth-tellers.
Overall, participants had difficulty detecting all types of deception. When viewing children answering yes–no questions about
a transgression (Experiments 1 and 5), participants’ performance was highly reliable. However, rating adults who provided truthful or fabricated accounts did
not produce a significant alternate forms correlation (Experiment 2). This lack of reliability was not due to the types of deceivers (i.e., children versus adults) or interviews (i.e., closed-ended
questions versus extended accounts) (Experiment 3). Finally, the type of deceptive scenario (naturalistic vs. experimentally-manipulated) could not account for differences
in reliability (Experiment 4). Theoretical and legal implications are discussed. 相似文献

Sequential lineups were offered as an alternative to the traditional simultaneous lineup. Sequential lineups reduce incorrect lineup selections; however, the accompanying loss of correct identifications has resulted in controversy regarding adoption of the technique. We discuss the procedure and research relevant to (1) the pattern of results found using sequential versus simultaneous lineups; (2) reasons (theory) for differences in witness responses; (3) two methodological issues; and (4) implications for policy decisions regarding the adoption of sequential lineups. 相似文献
