Non-monotonicity and Informal Reasoning: Comment on Ferguson (2003)

In this paper, it is argued that Ferguson’s (2003, Argumentation 17, 335–346) recent proposal to reconcile monotonic logic with defeasibility has three counterintuitive consequences. First, the conclusions that can be derived from his new rule of inference are vacuous, a point that as already made against default logics when there are conflicting defaults. Second, his proposal requires a procedural “hack” to the break the symmetry between the disjuncts of the tautological conclusions to which his proposal leads. Third, Ferguson’s proposal amounts to arguing that all everyday inferences are sound by definition. It is concluded that the informal logic response to defeasibility, that an account of the context in which inferences are sound or unsound is required, still stands. It is also observed that another possible response is given by Bayesian probability theory (Oaksford and Chater, in press, Bayesian Rationality: The Probabilistic Approach to Human Reasoning, Oxford University Press, Oxford, UK; Hahn and Oaksford, in press, Synthese).     

(STILL) DISAGREEING ABOUT CLIMATE CHANGE: WHICH WAY FORWARD?

Why does climate change continue to be a forceful idea which divides people? What does this tell us about science, about culture, and about the future? Despite disagreement, how might the idea of climate change nevertheless be used creatively? In this essay I develop my investigation of these questions using four lines of argument. First, the future risks associated with human‐caused climate change are severely underdetermined by science. Scientific predictions of future climates are poorly constrained; even more so the consequences of such climates for evolving human socio‐technological and natural ecosystems. Second, I argue that to act politically in the world, people have to pass judgments on the facts of science; facts do not speak for themselves. Third, because these judgments are different, the strategic goals of policy interventions developed in response to risks associated with future climate change are inevitably multiple and conflicting. Finally, reconciling and achieving diverse goals requires political contestation. “Moving forward” on climate change then becomes a task of investing in the discursive and procedural preconditions for an agonistic politics to work constructively, to enable ways of implementing policies when people disagree.     

Youthful Arrest and Parental Support: Gendered Effects in Straining the Parent–Child Relationship

Much research confirms the importance of the quality of the parent–child relationship on youth involvement in delinquency. Yet, few have examined this in reverse order, that is, how an arrest for delinquency impacts the parent–child relationship. This article explores the effects of arrest on the child’s perceived level of parental support using youth survey data for the nation. Among non-arrested youth, parental support experiences a gradual decline during the early teen years, and a considerable rebound in the late teen years. Among arrested youth, support shows sharper drops and recoveries over the teen years. Controlling for a set of social, legal, and demographic items, we examine the effects of the number of arrests on parental support with multinomial logistic regression, noting several gender effects. First, we find that arrests predict lower levels of support for mothers, but not for fathers. An equally noteworthy finding is that boys report more parental support than girls do, regardless of parent gender.     

Is Minority Stress in the Eye of the Beholder? A Test of Minority Stress Theory with Christians

Studies using minority stress theory have focused on the experiences of numerical and social power minorities, though majority individuals may also perceive themselves to be minorities. We explored minority stress theory among a sample of members of a numerically and socially dominant group: Christians in the USA. Perceiving oneself to be a member of a minority as a Christian was associated with stress indirectly via perceived experiences of faith-based discrimination (i.e., harassment due to being Christian). Being more open about one’s religion moderated the relationship between experiences of faith-based discrimination and stress, such that those who were open about their faith reported a stronger relationship between experiences of faith-based discrimination and stress. These findings indicate that perceptions of minority status are important to understanding stress and have implications for minority/majority dialogues.     

Sense of Community and Academic Engagement in the Seminary

This study examined the associations of sense of community (SOC) and academic engagement in a seminary. The seminarians (N?=?300) completed the Classroom Sense of Community Inventory (CSCI)–School Form, and Utrecht Work Engagement Scale–Student Version. Results showed that a perception that the seminary provided a positive learning community for the young people. For the sense of social community, the participants’ rating of the seminary was low. Regression results showed that SOC significantly predicted academic engagement. Suggestions are included on how to foster community spirit to become more psychologically meaningful for holistic education in the seminary.     

Emotional reactivity and blood pressure elevations: anxiety as a mediator

There is a strong link between emotional reactivity and hypertension, yet little research to date has examined mediators of this relationship. Ourstudy investigated the mediating roleof anxiety on the relationship between emotional reactivity and blood pressure elevations. Participants were226 hypertensive patients (93 men and 133 women, Mean age = 53.09, SD = 13.88 years), purposivelydrawn from the General Outpatient Department in University of Calabar Teaching Hospital, Calabar, , Nigeria. . Measures for data collection were Emotional Reactivity Scale, State Trait Anxiety Inventory, and the Mercury Sphygmomanometer. Hayes PROCESS macro for SPSS which uses a regression-based, path-analytical framework, was employed in analysing the data. Results showed that emotional reactivity was positively associated with blood pressure elevations. Anxiety was positively associated with blood pressure elevations. Anxiety also fully mediated the relationship between emotional reactivity and blood pressure elevations, even after adjusting for the control variables (e.g., age, family history of hypertension, and educational status). The finding suggests that being less emotionally reactive is associated with a decrease in disabling influences of anxiety, thereby contributing to lower levels of mean arterial blood pressure. The findings may be helpful in improving prevention, control and management of hypertension in healthcare.     

Comparing Business School Faculty Classification for Perceptions of Student Cheating

Faculty continue to address academic dishonesty in their classes. In this follow-up to an earlier study on general perceived faculty student cheating, using a sample of business school faculty, we compared three levels of faculty classification: full-time non-tenure track (NTT, n?=?86), full-time tenured/tenure-track (TT, n?=?66), and part-time adjuncts (A, n?=?71). Results showed that NTTs perceived higher levels for three different types of student cheating, i.e., paper-based, forbidden teamwork, and hiring someone to take an exam. In addition, NTTs were more likely to report a student for cheating. NTTs reported a higher course load and average class size, and average class size was positively related to all five types of cheating measured. Given the predicted increase in NTTs across all disciplines, making sure that all faculty, (but especially NTTs), have the resources needed to deter student cheating is important. All faculty have an obligation to hold students accountable for their behavior. Individual integrity is paramount; and it is what employers expect. Regardless of the chosen field or discipline, an employer’s expectations, in terms of character, is to hire individuals who possess a level of honesty that is above reproach. Addressing cheating is an obligation that all faculty need to address purposefully. Providing resources to help faculty address cheating is critical. Resources might include conflict resolution training to provide instructors with the necessary guidance so that they can better handle these difficult situations. This is important not only for the student while in school, but also for a university/college’s reputation.     

Developmental changes in inspection time: what a difference a year makes

This paper provides a partial replication and extension of a classic longitudinal study by Nettelbeck and Wilson [J. Exp. Child Psychol. 40 (1985) 1] that compared the relative influence of maturation and task experience on developmental changes in inspection time (IT). In the study reported in this paper 226 children aged between 6 and 9 were tested on an IT task in Year 1 and immediately retested to assess the importance of task familiarity. They were also retested 1 year and 2 years later. Counter to Nettelbeck and Wilson's conclusion, analyses of these data comparing the relative difference made by age maturation and by task experience revealed that task experience has a much bigger effect on children's IT than maturation. The implications of this for wider theoretical interpretations of the relationship between IT and development are discussed.
