When people are in dispute with their neighbours, there are multiple routes to resolution, and different services have a range of remits to support it. This article explores how noise complaints are reported to dispute resolution mediation and local council environmental services in the United Kingdom. A collection of 315 recorded telephone calls were transcribed and analysed using discursive psychology, underpinned by conversation analytic methods. Analysis focused on how the same kinds of noise complaint were formulated for the remit and provision of the service called. In mediation calls, callers directly attributed the source of the noise to the agent of its production (e.g., “it's about the neighbour”). However, reference to “the neighbour” was typically omitted (at least initially) in calls to environmental health services (e.g., “I need to speak to someone about disturbance”). This comparative analysis of different settings reveals the significance of service remit for the design of complaints and the relevance of attributing cause in making a case for aid. Comparing two settings provides a propitious opportunity to demonstrate that noise is not a physically objective phenomenon or neutral category but institutionally formulated social conduct. 相似文献

发展性阅读障碍的缺陷本质一直是研究者们关注和争论的焦点。近些年, 有研究者提出了一种新的理论假设——噪音抑制缺陷假设, 并得到了许多研究证据的支持。这种缺陷在视觉和听觉通道中均存在, 说明阅读障碍具有多感觉/一般性噪音抑制缺陷。但也有研究者指出知觉噪音抑制本质上反映了注意的功能, 因而这种缺陷可能是由注意缺陷导致的。目前还缺乏直接证据支持汉语阅读障碍存在噪音抑制缺陷。最后本文对该领域未来的发展方向做出展望。 相似文献

不同的认知诊断模型(CDM)对反应数据中噪音的抗干扰能力不同,在评估CDM性能的模拟实验中,反应数据中所含噪音的大小是十分重要的实验条件。由于噪音的内隐性,为应用中选用相应的CDM带来困难。本文在认知模型已知条件下,欲使用MHCI和NHCI指标评估认知诊断测验的反应数据(0, 1评分)中噪音的大小。模拟实验表明,两指标与噪音存在明显的统计规律。尤其是以NHCI为主要自变量对噪音进行预测的回归方程中,回归模型解释率均接近90%;以此实现对噪音的有效预测,从而为选择CDM提供一个参考。 相似文献

非稳态噪声对动物行为及心脏自由基损伤的影响 总被引:4,自引:0,他引:4
本研究用采集的多用木工机床和冲击电钻发出的噪声对 5天、1 0天和 2 0天三个噪声干扰组的动物进行干扰 ,以研究非稳态噪声对动物行为及心脏组织自由基损伤的影响。结果发现 ,非稳态噪声可引起动物旷场反应中走格数减少 ,站立及洗脸次数增加 ,并可诱发心脏组织的自由基反应 ,导致心脏组织的损害。因此得出结论 :①非稳态噪声可以对动物行为产生影响 ,并随着噪声暴露时间的延长而增强 ;②非稳态噪声可以造成心脏组织的自由基损伤。这一现象提示自由基损伤是介导噪声对心脏功能影响的重要因素之一。 相似文献

It has been suggested that the concreteness effect in short-term memory (STM) is a consequence of concrete words having more distinctive and richer semantic representations. The generation and storage of visual codes in STM could also play a crucial role on the effect because concrete words are more imaginable than abstract words. If this were the case, the introduction of a visual interference task would be expected to disrupt recall of concrete words. A Dynamic Visual Noise (DVN) display, which has been proven to eliminate the concreteness effect on long-term memory (LTM), was presented along encoding of concrete and abstract words in a STM serial recall task. Results showed a main effect of word type, with more item errors in abstract words, a main effect of DVN, which impaired global performance due to more order errors, but no interaction, suggesting that DVN did not have any impact on the concreteness effect. These findings are discussed in terms of LTM participation through redintegration processes and in terms of the language-based models of verbal STM. 相似文献

The role of extrafoveal information in visual short-term memory has been investigated relatively little, and, in most existing studies, using verbalisable stimuli susceptible to the recruitment of long-term memory (LTM). In addition, little is known about the impact of extrafoveal information available pre- and posttarget foveation, as it is typical to provide extrafoveal information prior to the foveation of memory targets. In this study, two object-position recognition experiments were conducted (each with two conditions) to establish the impact of extrafoveal information provided before and after the foveation of memory targets. Stimuli comprised 1/f noise discs that minimised the recruitment of LTM by eliminating verbal and semantic cues. Overall, a greater hit rate was found where extrafoveal information was available; however, performance analyses in which extrafoveal information was considered relative to the temporal lag at which target stimuli were foveated reveals both costs and benefits. A beneficial effect arose only where extrafoveal information was provided after the target had been foveated, but not prior to target foveation. Findings are discussed in terms of recency and extrafoveal perception effects, incorporating a postfoveation object-file refresh mechanism. 相似文献

We investigated the effects of age, background babble, and acoustic distortion of the word itself on serial position memory in a series of experiments involving six different auditory environments (quiet, and 12-talker background babble presented between, overlapping, or concurrent with word presentation or with two kinds of distortion applied to the words). To control for hearing, the level of babble or distortion was adjusted so that younger and older adults could hear the words equally well. Although the presence of continuous and word-flanking background babble adversely affected memory in the early serial positions in both age groups, only older adults' memory was adversely affected in the later serial positions. Moreover, younger adults' memory was not affected by acoustic word distortion, whereas one of the two types of temporal distortion adversely affected memory for later serial positions in older adults. The exact pattern of impairment and its interaction with age suggests that memory in older adults is more affected than that in younger adults in complex listening situations because they either need more time or have to employ more attentional resources to segregate different auditory streams, thereby depleting the pool of resources available for memory encoding. 相似文献

The authors investigated how tracking performance, submovement organization, pen pressure and muscle activity in forearm and shoulder muscles were affected by target size in a 2D tracking task performed with a pen on a digitizer tablet. Twenty-six subjects took part in an experiment, in which either a small dot or a large dot was tracked, while it moved quasirandomly across a computer screen at a constant velocity of 2 cm/s. The manipulation of precision level was successful, because mean distance to target and the standard deviation of this distance were significantly smaller with the small target than with the large target. With a small target, subjects trailed more behind the center of target and used submovements with larger amplitudes and of shorter duration, resulting in higher tracking accuracy. This change in submovement organization was accompanied by higher pen pressure, while at the same time muscle activity in the forearm extensors and flexors was increased, indicating higher endpoint stability. In conclusion, increased precision demands were accommodated by both a different organization of submovements and higher endpoint stability in a 2D tracking task performed with a pen on a digitizer tablet. 相似文献
