'Anti-Oppressiveness': Critical Comments on a Discourse and its Context

This paper identifies and aims to explain an apparent dissonancebetween the dominance in Britain of ‘anti-oppressive’social work discourse and the socio-political context surroundingits use; a context often claimed to feature excessive regulationand control. Pursuing this, some politically radical aims associatedwith ‘anti-oppressiveness’ are spelt out, and thedifficulty of achieving these in an unconducive climate is discussed.Then, a distinction made by Robert Merton between ‘latent’and ‘manifest’ functions is used to suggest thatthe manifest radicalism of ‘anti-oppressive’ discoursecan helpfully be distinguished from some latent largely unrecognisedconsequences of its use – not consequences with politicallyradical impact, but with a social meaning congruent with a climateof control. It is concluded that the ‘success’ ofanti-oppressive discourse might well be viewed as requiringmore of the kind of critical analysis that the discourse itselfwas supposed to espouse.     

Income Diversity,Technology Choice and Agricultural Research Policy in Sub‐Saharan Africa

This article makes an initial analysis of the implications of income diversification for technical change and agricultural research policy in Africa, leading to two insights. First, that the dilution effect of income diversification means that, as the proportion of non‐farm income increases, so must the expected gains from adopting a new agricultural technology. Second, that diversified producers will face disproportionately large transactions costs associated with information acquisition to inform technology choice decisions. Two hypotheses about how diversified producers are likely to react are then explored. Both point to the conclusion that income diversification among the poor is likely to constrain significantly the direct poverty impacts of agricultural research. The policy implications of these findings are then considered.     

Revisions of the Fish Invasiveness Screening Kit (FISK) for its Application in Warmer Climatic Zones,with Particular Reference to Peninsular Florida

The initial version (v1) of the Fish Invasiveness Scoring Kit (FISK) was adapted from the Weed Risk Assessment of Pheloung, Williams, and Halloy to assess the potential invasiveness of nonnative freshwater fishes in the United Kingdom. Published applications of FISK v1 have been primarily in temperate‐zone countries (Belgium, Belarus, and Japan), so the specificity of this screening tool to that climatic zone was not noted until attempts were made to apply it in peninsular Florida. To remedy this shortcoming, the questions and guidance notes of FISK v1 were reviewed and revised to improve clarity and extend its applicability to broader climatic regions, resulting in changes to 36 of the 49 questions. In addition, upgrades were made to the software architecture of FISK to improve overall computational speed as well as graphical user interface flexibility and friendliness. We demonstrate the process of screening a fish species using FISK v2 in a realistic management scenario by assessing the Barcoo grunter Scortum barcoo (Terapontidae), a species whose management concerns are related to its potential use for aquaponics in Florida. The FISK v2 screening of Barcoo grunter placed the species into the lower range of medium risk (score = 5), suggesting it is a permissible species for use in Florida under current nonnative species regulations. Screening of the Barcoo grunter illustrates the usefulness of FISK v2 as a proactive tool serving to inform risk management decisions, but the low level of confidence associated with the assessment highlighted a dearth of critical information on this species.     

Human resource development in small organizations

This article draws upon case-study research into human resource development (HRD) within three small organizations in the north west of England. It positions the case-study work within an overall framework of doctoral research and summarizes the research design; discusses the characteristics and values of small organizations and how they influence HRD policies and practices: presents findings and conclusions about HRD in the case-study organizations, focusing in particular upon one case in the voluntary sector; compares and contrasts the different models of HRD in the three cases; and concludes with some suggestions for further research.     

Short- and long-term effects of divorce and separation on housing tenure in England and Wales

This paper investigates the effects of marital and non-marital separation on individuals’ housing tenure in England and Wales. We apply competing risks event history models to data from the British Household Panel Survey and the UK Household Longitudinal Study to analyse the risk of a residential move to different tenure types, for single, married, cohabiting, and separated men and women. Separated individuals are more likely to move and experience a tenure change than those who are single or in a relationship. Among separated people, private renting is the most common outcome of a move; however, women are also likely to move to social renting, whereas men tend to move to homeownership. This pattern persists when we account for time since separation and order of move, indicating a potential long-term effect of separation on housing tenure. This long-term effect is especially pertinent to separated women who cannot afford homeownership.     

APPROPRIABLE RENTS FROM YELLOWSTONE PARK: A CASE OF INCOMPLETE CONTRACTING

The history of Yellowstone Park is best understood in the context of the theory of the firm as developed by Armen Alchian. In the late nineteenth century, the Northern Pacific Railroad recognized the potential amenity rents from Yellowstone and captured them by vertically integrating its monopoly on transportation to the region with the supply of tourist facilities in the park. This gave the railroad de facto ownership of the park that lasted until automobiles were allowed to enter in 1915. Thereafter the tragedy of the commons ensued and rents were dissipated instead of maximized.     

Infant‐Directed Speech Facilitates Word Segmentation

There are reasons to believe that infant‐directed (ID) speech may make language acquisition easier for infants. However, the effects of ID speech on infants' learning remain poorly understood. The experiments reported here assess whether ID speech facilitates word segmentation from fluent speech. One group of infants heard a set of nonsense sentences spoken with intonation contours characteristic of adult‐directed (AD) speech, and the other group heard the same sentences spoken with intonation contours characteristic of ID speech. In both cases, the only cue to word boundaries was the statistical structure of the speech. Infants were able to distinguish words from syllable sequences spanning word boundaries after exposure to ID speech but not after hearing AD speech. These results suggest that ID speech facilitates word segmentation and may be useful for other aspects of language acquisition as well. Issues of direction of preference in preferential listening paradigms are also considered.     

Some subjective bayesian considerations in the selection of models

Some considerations relating to the post-data selection of models are discussed. These include some difficulties with orthodox theory, implementation of the likelihood principle, and Bayesian tests of hypotheses.
