This paper identifies a number of children's voices within qualitative academic writing. It suggests that researchers can discover a variety of children's voices by employing reflexive techniques to ensure that their interpretations are not influenced by their personal prejudice, or the ethics, tools, roles and theories of their professional paradigm. It concludes that those who work with children may be able to reinforce the theme of the UN Convention on Rights of the Child by employing this reflexive approach to enable them to attribute equal status to the views of all the children whom they encounter. 相似文献

Summary. Origin–destination statistics have been produced from the last three UK censuses. The paper describes what is new about the 2001 census interaction data on migration and commuting, considers the disclosure control methods that were applied to cells containing small values and demonstrates the problems that are associated with making comparisons with 1991 data. The effect of small cell adjustment procedures on the interaction data sets is investigated by means of selective analyses at different spatial scales. Some recommendations are made in light of the problems that were manifest in 2001. 相似文献

This paper explores an infrequently discussed methodological divide within qualitative research; that between conscious and unconscious accounts of organizational processes. The paper makes use of an empirical case study of problems encountered in the growth of a high-technology company. The conscious accounts of growth treat members of the firm as knowledgeable agents whose understandings are then drawn upon to generate an account of growth in terms of interrelated processes of power, meaning and legitimacy. These conscious accounts are then complemented through an exploration of unconscious dynamics in the personality of the entrepreneur, the work group and the `family' structure of the firm. It is argued that the key shift in moving between conscious and unconscious interpretation, involves the bracketing of the reality claims implicit in conscious rationalizations, and a re-listening to research material as a largely unconscious projection of individuals' `inner worlds'. With unconscious interpretations, the character of language, its emotional content and in particular the sources of individual and group anxiety all realize a central importance. Despite the established divide in the literature between these two forms of interpretation, it is argued that the case suggests the value and necessity of their integration, particularly for the understanding of creativity. 相似文献

Hedayat et al. [1988a. Sampling plans excluding contiguous units. J. Statist. Plann. Inference 19, 159–170; 1988b. Designs in survey sampling avoiding contiguous units. In: Krishnaiah, P.R., Rao, C.R. (Eds.). Handbook of Statistics, vol. 6. Elsevier, Amsterdam, pp. 575–583] first introduced balanced sampling designs for the exclusion of contiguous units. Sampling plans that excluded the selection of contiguous units within a given sample, while maintaining a constant second-order inclusion probability for non-contiguous units, were investigated for finite populations of N units arranged in a circular, one-dimensional ordering. There remain many open questions about the existence of such plans and their extension to plans excluding adjacent units. We present new generation techniques and new balanced sampling plans for the exclusion of adjacent units under finite, one-dimensional, circularly and linearly ordered populations. 相似文献

Communicating about the health effects of fish and seafood may potentially result in a conflict situation: increasing intake is desirable because of health and nutritional benefits, but higher consumption may also lead to an increased intake of potentially harmful environmental contaminants. In order to anticipate the communication challenge this conflict may pose, the research presented here aimed to assess the impact of risk/benefit communication on Belgian consumers' fish consumption behavior and fish attribute perception. Data were collected in June 2005 from a sample of 381 women, aged between 20 and 50 years. An experimental design consisting of four message conditions (benefit‐only; risk‐only; benefit‐risk; and risk‐benefit) combined with three information sources (fish and food industry; consumer organization; government) was used. Exposure to the benefit‐only message resulted in an increase from a self‐reported fish consumption frequency of 4.2 times per month to an intended fish consumption frequency of 5.1 times per month (+21%), while fish attribute perceptions only marginally improved. The risk‐only message resulted in a strong negative perceptual change in the range of two points on a seven‐point scale. This translated into an 8% decrease of behavioral intention (from eating fish 4.5 times per month to an intention of eating fish 4.1 times per month). Balanced messages referring to both risks and benefits yielded no significant change in behavioral intention, despite a significant worsening of fish attribute perception. The presentation order of benefits and risks in the balanced message showed a tendency to affect both behavioral intention and attribute perception, with the first message component being most influential. Information source did not yield any significant impact either on behavioral intention or on attribute perceptions, independent of the message content. The results from this study provide valuable insights for future risk/benefit and balanced communication about seafood. 相似文献

Conceptualizing growth trajectories of organizations in organismic terms describing transitions through a series of stages, from birth to maturity, has considerable intuitive appeal. Recently, the assumptions underpinning the life‐cycle perspective (growth is linear, sequential, deterministic and invariant) have been argued not to pertain to organizations. This paper reviews the literature on life‐cycle growth models, traces the development of a growing sophistication of conceptualizing growth and highlights some of the limitations of the literature. The authors make a contribution by proposing an alternative conceptual framework for thinking about growing businesses. The framework consists of two dimensions. First, a typology of key issues that are likely to be faced by all growing firms, and the discussion is shaped by M. Gladwell's (The Tipping Point: How Little Things Can Make a Big Difference. Boston: Little Brown, 2000) notion of ‘tipping points’. The second dimension is developed by drawing on the knowledge management literature and the concept of absorptive capacity ( Cohen, W.M. and Levinthal, D.A. (1990 ). Absorptive capacity: a new perspective on learning and innovation. Administrative Science Quarterly, 35 , 128–152). This concept is applied to a discussion of the state of an organization regarding its ability to absorb and use new knowledge. Further, it is suggested that the framework has value for both policy and practice and can be used for the design and specification of interventional support and, to identify and evaluate their impact. If interventions are to help firms to grow, they must provide the right knowledge or support in forms that the firm can utilize. Together, these two dimensions provide a framework to examine firm growth issues and to analyse the effectiveness of different interventions on firms in different states within this framework. 相似文献
