Creative industries are firms which are characterized largely by the labour inputs of creative individuals, and surrounded by a degree of rhetoric as to their significance, but are a comparatively under‐researched sector. In this study we developed a research framework which integrated entrepreneurial cognition, entrepreneurial orientation and firm capabilities and explored the relationships between these variables, market conditions and the performance of small creative industry enterprises. The data suggest that high growth small firms are characterized by well‐developed internal capabilities allied to an entrepreneurial orientation and that the combination of the various sub‐attributes associated with each of these appear to be especially salient under conditions of intense competition. The policies, managerial and educational implications of the findings are discussed.  相似文献

This paper reports an evaluation of a rural activity project for people with learning difficulties. The project is situated in (but not a regular part of) an agriculture college. Both statutory and voluntary interests are represented in the management of the scheme, which is funded by the All Wales Strategy for the Mentally Handicapped through the local authority. Despite the widespread presence of ideas about normalization and carer participation, key stakeholders in the project appeared to draw on various aspects of three different models in describing, assessing and participating in the work of the scheme: a training for work model, a personal and social growth model, and an education for life model. We explore the question of whether such contrasting views can be tolerated in a single project, and their implications for policy and practice decisions. Each model has its distinctive consequences for project aims, selection, programme planning, staffing requirements, future development objectives and desirable project outcomes. The debate has implications for the way in which policies of normalization are operationalized in and beyond the field of learning difficulties.  相似文献

Will those residing in urban enclaves—enclosed socially homogenous residential communities protected by private security—have a lower level of civic concern as compared to those who do not reside in such enclaves? Reich's (1991) work suggests that this is to be expected. To conduct an empirical test, two random samples were drawn from two areas of New York City, one a residential enclave—Battery Park City—the other a non-enclave—Chelsea. The analysis establishes that those who do not live in the enclave have a statistically significant higher level of civic concern. Sample respondent years of education, age, income, gender, and career (arts/business) differences were employed as control variables; after having introduced each control variable independently, the main research hypothesis was sustained.  相似文献

Scientific ideas neither arise nor develop in a vacuum. They are always nutured against a background of prior, partially conflicting ideas. Systemic hypothesistesting is the problem of testing scientific hypotheses relative to various systems of background knowledge. This paper shows how the problem of systemic hypothesis-testing (Sys HT) can be systematically expressed as a constrained maximimization problem. It is also shown how the error of the third kind (E III) is fundamental to the theory of Sys HT.The error of the third kind is defined as the probability of having solved the ‘wrong’ problem when one should have solved the ‘right’ problem. This paper shows howE III can be given both a systematic as well as a systemic treatment. Sys HT gives rise to a whole host of new decision problems, puzzles, and paradoxes.  相似文献

This paper analyses the decision‐making process of health authorities under New Labour in the NHS through a study of their qualitative responses to questionnaires. We find a considerable frustration and cynicism with the government's plans for reform, with its interference at the local level with services, and an acknowledgement of the differences between health authorities’ practice and what they believe the government requires, with, often, only minimal effort being made attempting to achieve new governmental performance targets. We conclude by making suggestions for an alternative strategy less likely to antagonize local health service providers.  相似文献

E-mail: i.paylor1{at}lancaster.ac.uk Summary One of the many consequences of injecting drug use is the potentialrisk to infectious blood-borne viruses. There is evidence thatthe risk of contracting Hepatitis C (HCV) is greater than thatof HIV. Despite repeated warnings from a variety of sourcesand thousands of new infections among drug users each year andrising incidents of ‘'crack’ injecting, successivegovernments have failed to address a public health emergencyof immense proportions - the HCV epidemic. This article exploresthis issue and the implications it has for social work.  相似文献

A new approach to the measurement of mentalizing is introduced. Instead of measuring the presence or absence of mentalizing capacity, the current study aimed at developing a mentalizing task that focuses on investigating biases in mentalizing through the use of ambiguous peer‐related social scenarios. The response consistency of 659 children was investigated in a community sample of children aged seven to 11. Confirmatory latent class analysis allocated children to three groups on the basis of their responses: an overly positive style (OP), a rational/neutral style (R) or an overly negative style (ON). Children classed as OP showed a greater likelihood of being above cut‐off on a population screen for externalizing disorder. Over a two‐year follow‐up period, the children who were classified as R were most likely to remain so whereas the OP and ON children were found to change group. The results are discussed in the context of social‐cognitive research in this age group. Further studies should examine the external validity of the mentalizing task because the results reported here concern only internal construct validity.  相似文献

ABSTRACT

Confidence intervals for the intraclass correlation coefficient (ρ) are used to determine the optimal allocation of experimental material in one-way random effects models. Designs that produce narrow intervals are preferred since they provide greater precision to estimate ρ. Assuming the total cost and the relative cost of the two stages of sampling are fixed, the authors investigate the number of classes and the number of individuals per class required to minimize the expected length of confidence intervals. We obtain results using asymptotic theory and compare these results to those obtained using exact calculations. The best design depends on the unknown value of ρ. Minimizing the maximum expected length of confidence intervals guards against worst-case scenarios. A good overall recommendation based on asymptotic results is to choose a design having classes of size 2 + √4 + 3r, where r is the relative cost of sampling at the class-level compared to the individual-level. If r = 0, then the overall cost is the sample size and the recommendation reduces to a design having classes of size 4.  相似文献

The mid-p is defined as the sum of the probabilities of all outcomes more extreme than an observed value, plus half of the probabilities of all outcomes exactly as extreme. On the one hand, it offers greater power than the standard p-value, but on the other, tests based on the mid-p statistic may have greater Type I error than their nominal level. This article investigates the mid p-value's properties under the estimated truth paradigm, which views p-values as estimators of the truth. The mid-p is shown to minimize the maximum risk for one-sided and two-sided tests.  相似文献
