AbstractFrequent claims that publics ‘misunderstand’ science ignore the contested definition of scientific uncertainty itself. Scientific uncertainty means different things in the natural sciences, social sciences and the humanities, while public controversies show that interpretations of scientific uncertainty have different implications for policy and decision-making. This prompts analysis of the ways that experts view scientific uncertainty and how they characterise the (mis)understandings of this uncertainty by policy-makers, media and publics. Experts from diverse academic fields define scientific uncertainty differently depending on their disciplinary background. For example, mathematics provides experts from the natural sciences with a practice language that facilitates communication with those sharing this cultural competence, but it does not suffice for engaging with wider audiences. Further, experts’ views of diverse publics come across as folk theories, in Arie Rip's terms, which, compiled from disparate pieces of information, can be used to fill a gap in the knowledge about publics. 相似文献

This chapter examines the role of leadership in overcoming social dilemmas within groups. First, based on prior theorising and research we present two alternative perspectives on leader endorsement in social dilemmas, an instrumental and a relational perspective. Next, we systematically compare these perspectives in a series of experiments investigating leadership in social dilemmas created within small groups in the laboratory. The results of our studies suggest that when their personal identity is salient, group members more strongly endorse leaders who are perceived to be instrumental in solving the freerider problem. In contrast, when a social identity is salient, members more strongly endorse leaders who fulfil their relational needs. Based on these findings we propose a differential needs model of leader endorsement in social dilemmas. 相似文献

Worsening traffic congestion and air quality has been associated with the proliferation of informal operation of private microbus and minibus in African cities. It is recognised that large buses hold the promise of relieving the growing congestion of African cities if they are managed efficiently and sustainably.It is in line with this that this study seeks to explore the reasons behind commuters’ non-preference of Metro Mass Transit (MMT) for intra-city commuting in Accra, Ghana. A revealed preference survey was administered to 134 commuters to find out the reasons behind their non-preference and their perception of the level of service (LOS) delivery of the Metro Mass Transit.The Study revealed that though Metro Mass Transit was 20% cheaper in terms of price, commuters perceived its service delivery as poor. Over-crowding of buses, non-adherence to time schedule, long in-vehicle time, perception of not getting access to seats, non-availability of bus at respondents’ origins and destinations, accessibility of alternative modes and long waiting times for buses accounted for the major reasons for non-preference.Metro Mass Transit Limited’s improvement in its service attributes especially in-vehicle time, waiting time, comfort, reliability and accessibility is a means of increasing its modal share. Adherence to these is the surest way to achieving the objective of promoting mass transit in Accra by shifting people from the use of unsustainable modes such as mini-buses and taxis to the use of efficient high capacity systems as Metro Mass Transit. 相似文献

Tram drivers have a difficult task in controlling one of the heaviest vehicles on the road whilst negotiating a complex road environment with multiple road users. Like all public transport drivers, tram drivers need to ensure passenger safety and to run on time. However, very little research has been conducted evaluating tram driving tasks and even less on evaluating tram drivers opinion on how other road users are affecting tram road safety. Therefore, the aim of this study is to investigate the key tram driving challenges, to identify the key road user factors affecting tram road safety as well as to explore the potential safety improvement initiatives on tram routes from the tram drivers’ viewpoint. The study incorporated five focus groups involving thirty tram drivers in Melbourne. The key themes emerged inductively from focus groups were identified through a data coding process. Outcomes of the focus groups revealed seven major challenges in tram driving: ensuring safety for all people in and around the tram, pressure for running on-time, maintaining constant concentration on roads, predicting other road users’ behavior in advance to avoid any crash incident, preventing passenger falls on board, accepting the operational constraints of trams and managing fatigue workloads. Tram drivers identified that other road users are unaware of safety issues around trams, have a poor understanding of road rules about driving with trams and often violate road rules around trams, and they mentioned this road user behaviors as the key challenges for safe tram driving. Tram drivers proposed rendering greater law enforcement on the tram network to penalize road users who are violating road rules around trams, introducing more safety campaigns and safety education to increase awareness among road users to improve tram road safety. Findings of this research enhance understanding of tram driving challenges, provide an in-depth knowledge of road user factors affecting tram road safety and suggest effective planning strategies for transit agencies to improve road safety. 相似文献

This paper examines the implications for academic careers of the apparent global trend towards marketisation and managerialism in higher education with reference to the UK and Germany. It discusses how university employers might exercise greater control over their employees, privileging research and international publication, and fragmenting the traditional unity of the academic role. The effect is to challenge the values of academic communities, subject individuals to greater uncertainty, competition and insecurity, and influence the shape and direction of academic careers. The paper notes how today’s academic careers could be understood in terms of Kanter’s three forms of career as well as the boundaryless and protean career. However, it argues that these approaches do not address the key issue in both the UK and German cases: the changed locus and exercise of power within the employment relationship. It concludes that, to understand how careers are changing, this power relationship and the context of career in general have to be taken into account. 相似文献

This study (N = 124) tested the main and interactive effects of alcohol consumption, egalitarianism, and right-wing authoritarianism (RWA) in relation to prejudice suppression in the natural environment of a British Public House (pub). Employing a quasi-experimental between-subjects design, participants who had consumed alcohol were worse at suppressing their prejudice than participants with no alcohol consumption. Further, the more participants endorsed egalitarian values, the more they were able to suppress their prejudice. This tendency was resistant to the effects of alcohol. By contrast, the stronger participants held RWA beliefs, the less they were able to suppress their prejudice. In addition, this tendency was accentuated by alcohol consumption. Results are discussed in terms of theoretical and practical implications. 相似文献

The authors suggest that the mental health system of the nation could benefit by more fully embracing the idea of mutual-help (i.e., self-help), and this collaboration could be facilitated by the utilization of a well-established clinical theory to elucidate the psychological processes at work within mutual-help organizations. The processes of change of the transtheoretical model is offered as one potential framework. This well-established model has been used to help psychologists better understand clinical and professional phenemonena, but, to date, has been used less frequently with non-professional interventions. This article applies the ten processes of change of the transtheoretical model to mutual-help organizations, focusing on four groups, including Alcoholics Anonymous (AA), Oxford House, GROW, and Schizophrenics Anonymous. The advantages of the transtheoretical model and its potential ability to act as a common language across clinical professionals and mutual-help organizations are discussed. In addition, advantages of bolstering the present mental health system using combinations of both forms of care along the recovery continuum are described. 相似文献

各级地方官作为维护治安职能的主要承担者,是关系地方治安好坏与否的关键因素。两汉社会的治安问题主要集中于三个方面:一是以豪强大姓为主、对社会治安严重破坏的地方恶势力;二是遭遇天灾人祸的诸多灾民、流民;三是官逼民反,以农民为代表的社会下层反抗势力。针对这些不同情况、不同性质的问题,许多齐鲁籍官吏采取了不同的措施和方法,并且留下大量施政范例,在社会治安方面为后人提供了有益的借鉴。 相似文献

Sydney Shoemaker leads today’s “neo-Lockean” liberation of persons from the conservative animalist charge of “neo-Aristotelians”
such as Eric Olson, according to whom persons are biological entities and who challenge all neo-Lockean views on grounds that
abstracting from strictly physical, or bodily, criteria plays fast and loose with our identities. There is a fundamental mistake
on both sides: a false dichotomy between bodily continuity versus psychological continuity theories of personal identity.
Neo-Lockeans, like everyone else today who relies on Locke’s analysis of personal identity, including Derek Parfit, have either
completely distorted or not understood Locke’s actual view. Shoemaker’s defense, which uses a “package deal” definition that
relies on internal relations of synchronic and diachronic unity and employs the Ramsey–Lewis account to define personal identity,
leaves far less room for psychological continuity views than for my own view, which, independently of its radical implications,
is that (a) consciousness makes personal identity, and (b) in consciousness alone personal identity consists—which happens to be also Locke’s actual view. Moreover, the ubiquitous Fregean conception of borders and the so-called “ambiguity
of is” collapse in the light of what Hintikka has called the “Frege trichotomy.” The Ramsey–Lewis account, due to the problematic
way Shoemaker tries to bind the variables, makes it impossible for the neo-Lockean ala Shoemaker to fulfill the uniqueness
clause required by all such Lewis style definitions; such attempts avoid circularity only at the expense of mistaking isomorphism
with identity. Contrary to what virtually all philosophers writing on the topic assume, fission does not destroy personal
identity. A proper analysis of public versus perspectival identification, derived using actual case studies from neuropsychiatry,
provides the scientific, mathematical and logical frameworks for a new theory of self-reference, wherein “consciousness,”
“self-consciousness,” and the “I,” can be precisely defined in terms of the subject and the subject-in-itself. 相似文献
