A diary study of distracted driving behaviours

The introduction and uptake of technology within road vehicles has readily advanced the capabilities and the functions that the driver of a road vehicle has available to them. While this has benefited the drivers’ productivity and entertainment behind the wheel, it has also heightened the possibility for distraction. Research into driver distraction to date has identified how technologies inside the vehicle may be used ineffectively and can compromise the safety of the road transport system. Yet, the factors that drivers state impact on their decision to engage with distracting technologies are less well known. This paper presents the first diary study into driver distraction. The study asked drivers to record all technological distractions that they engaged with across a 4-week period, as well as interactions that they ignored or choose not to engage with. The diary entries include the technologies drivers interacted with and the conditions surrounding this, as well as external factors that drivers cited to influence their decision to interact. Primarily, factors relating to the task itself were found to be of most importance to the drivers’ decision to engage. Differences were also found in how drivers stated they compensated for any engagement with distracting tasks. This has important consequences for the design and integration of technological devices into the vehicle. The novel application of the method offers insights into the naturalistic conditions surrounding drivers’ involvement with distracting technologies. The method is also reviewed on its applicability to the study of driver distraction.     

Factors explaining driver yielding behaviour towards pedestrians at courtesy crossings

Courtesy crossings are pedestrian crossing facilities where drivers are not legally required to stop for pedestrians, but are encouraged to do so by design elements such as stripes, coloured or textured road surfaces, visual narrowings of the carriageway, and ramps. There is little empirical evidence on drivers' behaviour or guidance on how to design these crossings. This paper analysed data for 937 interactions between drivers and pedestrians at 20 crossings across England, comparing driver yielding behaviour at courtesy crossings and at zebras (marked unsignalised crossings, where drivers are legally required to stop); and identifying the design elements associated with yielding behaviour at courtesy crossings. The analysis controlled for crossing stage; characteristics and situation of pedestrians and vehicles; characteristics of the road and site; and time context. Driver yielding behaviour was analysed for each separate traffic lane that pedestrians need to cross. We found that all four design elements considered (stripes, coloured/textured surface, visual narrowing, and ramps) increased the propensity of the first vehicle to stop and of any vehicle to stop. A before-after analysis then showed that adding a new element (stripes) to a courtesy crossing led to an increase in yielding rates from 20% to 97%. Overall, we found evidence supporting the use of multiple design elements in courtesy crossings. We discuss the implications of these findings for transport policy and urban design.     

Psychotherapy as a skilled practice

While psychotherapy is related to both science and art, it is primarily a craft activity requiring the development of skilful practice, epitomized by the discipline of the analytic attitude. In terms of the forms of knowledge outlined by Aristotle, this places psychotherapy in the realm of ‘technê’ (arts and craft) rather than epistêmê (science). In particular, the technê of psychotherapy is concerned with the development of phronesis (practical wisdom) in both patient and analyst and its ultimate aim is concerned with the promotion of eudaimonia, a state of well-being considered by Aristotle to be definitive of ‘the good life’. It is therefore fundamentally an ethical endeavour. The nature of psychotherapeutic skill is illustrated by analogy with three other forms of technê – music, meditation and pottery. Clinical examples illustrate the crafting of interpretations and the art of patient holding.     

Cleaning versus replacement in power plant air preheaters: a comparison between deterministic and stochastic goal programming models

Power plants lose efficiency when the air preheater elements are not replaced or cleaned as they deteriorate. Replacing is more expensive than cleaning but more secure to preserve power and lifetime. How many baskets should be then replaced and how many cleaned to achieve ‘satisficing’ goals of cost, power and lifetime? We design deterministic/stochastic goal programming approaches to this problem and develop a decision case for usual preheaters. Some discrepancies in results between both approaches appear, the deterministic model advising to replace less baskets than the stochastic, which is plausible due to the risk variable.

On the Relationship Between Attitude Involvement and Attitude Accessibility: Toward a Cognitive-Motivational Model of Political Information Processing

A model of the relationship between attitude involvement and attitude accessibilitywas developed and tested. The model specifies that attitude involvement leads to selective(biased) issue-related information-gathering strategies, which in turn produce extreme andunivalent (unambivalent) attitudes. Finally, attitudes associated with univalent and extremeunderlying structures should occasion relatively little decision conflict and thus should be highlyaccessible. Questionnaire response data gathered in a national telephone survey and from twosamples of undergraduates revealed that both attitude extremity and attitude ambivalence onselected political issues mediated the relationship between attitude involvement and attitudeaccessibility. Some findings indicated that selective processing mediated the relationshipbetween attitude involvement and attitude extremity and ambivalence. Discussion focuses on theprocesses linking involvement to accessibility, the factors that moderate theambivalence-accessibility relationship, and the relevance of the model to media-based primingeffects and tothe nature of public opinion and the survey response.     

中小学生欺负问题中的性别差异的研究

本研究运用修订的Olweus欺负/受欺负问卷对我国城乡4726名中小学生进行调查,考察了欺负与受欺负的性别差异问题,结果表明1.小学生和初中生受欺负的发生率不存在显著的性别差异,而男孩中欺负他人的比率却极显著地高于女孩;2.中小学生对欺负问题的态度存在显著的性别差异,初中生对欺负的态度受性别和年级的交互作用的影响;3.中小学生不同欺负方式的发生率存在显著的性别差异,男生直接的身体欺负和间接欺负显著地高于女生,而言语欺负的性别差异并不显著.     

Knowledge and Attitudes of Hospital Nurses in Italy Related to Near-Death Experiences

I distributed Nina Thornburg's Near-Death Phenomena Knowledge and Attitudes Questionnaire to 750 nurses in three Verona hospitals, and received 476 completed questionnaires. Questionnaire respondents had a modest knowledge of near-death experiences (NDEs). Nevertheless, respondents expressed a positive attitude towards NDEs in general, and towards patients who had had NDEs. Thirty-four percent of the nurses had personally encountered NDErs, and those nurses reported a higher level of knowledge than their colleagues who had not had that opportunity. Furthermore, in relation to the global sample, nurses who had encountered an NDEr showed attitudes that were more positive regarding both the NDE itself and the type of assistance they offered NDErs.     

Can Voters Predict Changes in Theor Own Attitudes?

Although scholars have established that voters have unstable preferences (e.g., Converse, 1964; Zaller, 1992) and that they are not accurate when recalling past preferences (e.g., Markus, 1986; Niemi, Katz, & Newman, 1980; Smith, 1984), existing research has not systematically explored whether voters can accurately predict the changing nature of their own opinions. The question of whether whether people recognize the instability of their political preferences was explored in a random sample of Pennsylvania registered voters who were surveyed in August and October 1996, during the presidential election campaign. The first survey elicited respondents' positions on two political issues (welfare reform and the environment) and on the two major candidates, and also asked them to estimate the likelihood that each of these positions would change during the next 2 months. The second survey elicited positions at that time and also asked voters to recall their prior positions. Measured both by expectations and recall, respondents tended to underestimate the degree to which their own positions would change or had changed over time. This research has implications for the use of public opinion polling and more broadly for the practice of democratic politics.

印象整饰对强迫服从后态度改变的影响

以194名大学生为被试,采用实验室实验法和利克特型态度量表,对Festinger和Carlsmith“强迫服从的认知性后果”实验进行了验证研究,并对个体印象整饰水平—自我监控力的差异对强迫服从后的态度中庸现象的影响作用进行了实验研究。结果表明：（1）自我监控性高低极端组在强迫服从后的态度得分不支持Festinger等实验的结果;（2）个体的印象整饰水平的差异对强迫服从中出现的态度中庸现象有显著影响作用。仅从个体内在的心理因素来解释复杂的社会行为是不够的,我们既要考虑个体自身的因素也要考虑外在环境的作用
