Drifting Further Apart? How Exposure to Media Portrayals of Muslims Affects Attitude Polarization

Political discourses about Muslim immigration in the media and on social networking sites (SNSs) are highly contentious and have the potential to further polarize societal segments, which may ultimately harm democratic processes. Especially on SNSs, politicians and citizens can circumvent journalistic filters often resulting in blatant and emotionally charged content. Using a two-wave panel design (N = 559), we investigated how positive and negative portrayals of Muslims in traditional media outlets and on SNSs influence anti-Muslim immigration attitudes among people who either agree or disagree with the encountered information. Our findings indicate that exposure to negative portrayals further reinforces anti-Muslim immigration attitudes among those who agree with the encountered information. In contrast, for those who disagree with the negative information, a backfire effect emerges, showing that anti-Muslim attitudes even decrease. This effect occurs for both SNSs and traditional media. Positive information about Muslims did not result in attitude polarization.     

Evangelical Environmentalists? Evidence from Brazil

While scholarship on the relationship between religions and environmental attitudes has been inconclusive, evangelical Protestants present an exception: they consistently report less environmental concern than other groups. However, prior studies have largely been conducted in the United States. Following a recent “contextual” turn, we revisit the assumption that universal cognitive and doctrinal factors drive the previously documented negative association between evangelicalism and environmental concern. Leveraging qualitative fieldwork, nationally representative surveys, and a survey experiment from Brazil, we find that evangelical and Pentecostal affiliation and church attendance are not associated with reduced environmental concern; that members of these groups simultaneously embrace otherworldly beliefs and advocate for this-worldly solutions to environmental problems; and that being primed to consider divine intervention increased support for environmental protection. Even in a tradition emphasizing orthodoxy, doctrine appears not to exert a universal influence, a finding we suggest results from different issue frames in the United States and Brazil.     

Study of unique merging behavior under mixed traffic conditions

Roads in developing countries carry mixed traffic with wide variations in static and dynamic characteristics of vehicles. The traffic flow is also generally devoid of lane discipline, with vehicles occupying any available road space ahead. In such a regime of traffic flow, the phenomena of merging of vehicles at intersections of two roads is complex, warranting further study. The merging maneuvers at T-intersections under congested traffic conditions were studied microscopically through video-recording. In congested situations, the merging vehicle attempts a complex merging maneuver to enter the main traffic stream. Two unique merging processes are commonly observed in mixed traffic: group and vehicle cover merging (these are generally not observed in countries such as US). The author is using these words first time in this study. These reflect the different types of driver behavior – merging in groups, and by taking cover of another vehicle. Probabilistic models for group and vehicle cover merging are developed that capture this unique merging behavior. Comprehensive microscopic data collection and extraction were carried out to study the merging process at T-intersection under congested conditions. Merging models were then estimated using maximum likelihood method with disaggregate data that was collected for a case study T-intersection in Chennai city, India. Such models can find applications in simulation of highly congested traffic flow in a realistic manner under mixed traffic conditions. They can also give insights on devising better traffic control measures at such intersections.     

The cost of treating substance use disorders: individual versus family therapy

This study examined the cost of substance use disorders treatment in a large healthcare organization. A survival analysis demonstrated that family therapy utilised the least number of sessions (M = 2.41) when treating substance use disorders followed by individual therapy (M = 3.38) and mixed therapy (M = 6.40). Family therapy was the least costly of the three types, at $124.55 per episode of care for a client, with individual therapy costing $170.22 and mixed therapy $319.55. The ratio of family therapists utilising family therapy was more than three to one compared to other licensed professionals. The percentages of clients coming back for more than one episode of care are fewest for family therapy (8.9%) followed by mixed therapy (9.5%) and individual therapy (12.0%).     

Children's judgements and emotions about social exclusion based on weight

This study examined children's judgements and emotions associated with weight‐based social exclusion using an ethnically diverse sample of one hundred and seventeen 9‐ and 13‐year‐old children. Children were interviewed about three scenarios depicting weight‐based exclusion in athletic, academic, and social contexts. Children's judgements of exclusion, emotions attributed to the excluder and excluded targets, and justifications for judgements and emotions were examined. Overall, children judged weight‐based exclusion to be wrong for moral reasons. However, they viewed weight‐based exclusion in athletic contexts as less wrong compared with academic contexts, and they used more social‐conventional reasoning to justify judgements and emotions attributed to excluders in athletic contexts compared with academic and social contexts. Children also expected excluded targets to feel negative emotions, whereas a range of positive and negative emotions was attributed to excluders. In addition, older children were more accepting of weight‐based exclusion in athletic contexts than in academic and social contexts. We discuss the results in relation to the development of children's understanding of, and emotions associated with, exclusion based on weight.     

Reasonably Traditional: Self–Contradiction and Self–Reference in Alasdair MacIntyre's Account of Tradition–Based Rationality

Alasdair MacIntyre's account of tradition–based rationality has been the subject of much discussion, as well as the object of some recent charges of inconsistency. The author considers arguments by Jennifer Herdt, Peter Mehl, and John Haldane which attempt to show that MacIntyre's account of rationality is, in some way, inconsistent. It is argued that the various charges of inconsistency brought against MacIntyre by these critics can be understood as variations on two general types of criticism: (1) that MacIntyre's account of tradition–based rationality presents a picture of rationality with inconsistent internal elements, and (2) that MacIntyre, in the act of presenting his picture of rationality, makes the sort of claims to which his own account of rationality denies legitimacy, and thus MacIntyre's account is self–referentially incoherent. In response to criticisms of the first sort, it is argued that MacIntyre can further clarify or develop his position to take the current criticisms into account without altering the fundamental aspects of his picture of rationality. In response to the charge of self–referential incoherence, it is argued that the charge rests on a mistaken understanding of MacIntyre's position and of the nature of justification. In dealing with these arguments, the author hopes to not only vindicate MacIntyre's account of rationality against the charges of some of its recent critics, but also to shed some light on the nature of arguments both for and against relativism and historicism.     

苏浚生生易学之研究——兼论苏浚调和理学与心学的方法

苏浚是明代后期著名的理学家和易学家。苏浚易学属于义理易学,具有心学易的色彩。苏浚易学的主要贡献在于提出了圣人洗心而作《易》的观念,这为后世注经者以心论《易》提供了"合法"诠释的前提。在苏浚看来,学习《周易》,固然要学习《周易》所蕴含的各种人事及其道理,但更重要的是要学习圣人之心。另外,苏浚采用人心涵具天理这一思路,既承认了天理的本体性地位,又突出了心的重要性,从而表现出调和理学与心学的理论努力。     

An effective metacognitive strategy: learning by doing and explaining with a computer‐based Cognitive Tutor

Recent studies have shown that self‐explanation is an effective metacognitive strategy, but how can it be leveraged to improve students' learning in actual classrooms? How do instructional treatments that emphasizes self‐explanation affect students' learning, as compared to other instructional treatments? We investigated whether self‐explanation can be scaffolded effectively in a classroom environment using a Cognitive Tutor, which is intelligent instructional software that supports guided learning by doing. In two classroom experiments, we found that students who explained their steps during problem‐solving practice with a Cognitive Tutor learned with greater understanding compared to students who did not explain steps. The explainers better explained their solutions steps and were more successful on transfer problems. We interpret these results as follows: By engaging in explanation, students acquired better‐integrated visual and verbal declarative knowledge and acquired less shallow procedural knowledge. The research demonstrates that the benefits of self‐explanation can be achieved in a relatively simple computer‐based approach that scales well for classroom use.
