Intrinsic Explanation and Field’s Dispensabilist Strategy

Abstract

Hartry Field defended the importance of his nominalist reformulation of Newtonian Gravitational Theory, as a response to the indispensability argument, on the basis of a general principle of intrinsic explanation. In this paper, I argue that this principle is not sufficiently defensible, and can not do the work for which Field uses it. I argue first that the model for Field’s reformulation, Hilbert’s axiomatization of Euclidean geometry, can be understood without appealing to the principle. Second, I argue that our desires to unify our theories and explanations undermines Field’s principle. Third, the claim that extrinsic theories seem like magic is, in this case, really just a demand for an account of the applications of mathematics in science. Finally, even if we were to accept the principle, it would not favor the fictionalism that motivates Field’s argument, since the indispensabilist’s mathematical objects are actually intrinsic to scientific theory.     

Exploring teenagers' adaptive and maladaptive thinking in relation to the threat of hiv infection

Abstract

Teenagers' HIV-preventive cognitions were explored within a protection motivation theory framework. Five hundred and seven adolescent men and women from two cohorts (sixteen and eighteen) completed a confidential postal questionnaire. The effect of demographic variables, previous sexual experience and appraisal of threat and coping resources upon HIV-relevant cognitions was investigated using path analysis. Cognitions promoting (adaptive) and inhibiting (maladaptive) preventive behaviour were considered. Anticipated condom use, intention to limit number of sexual partners and willingness to consider an HIV antibody test were included as adaptive HIV-preventive cognitions. Coping appraisal measures were strongly associated with anticipated condom use but threat appraisal measures were not. Gender, previous sexual experience, coping appraisal measures and denial accounted for 33% of the variance in anticipated condom use. Overall the results provided qualified support for Protection Motivation Theory. Implications for health education are highlighted.     

Organizational entry and exit: An exploratory longitudinal examination of early careers

New college graduates' perceptions of organizational entry constructs were measured at the end of the first year of employment and related to subsequent turnover as well as work attitudes 3 years later in a longitudinal design. The research design examined the simultaneous effects of entry constructs for the first time in an exploratory model. The combined effects of individual readiness, organizational tactics, individual tactics, entry process perceptions, perceived job characteristics, learning, expectations, and coping responses on subsequent turnover and job attitudes of newly employed college graduates were investigated using hierarchical logistic regression. Aspects of preemployment anticipation, organization receptivity, adaptation difficulty, meeting with person previously in the position, feedback seeking, and organization attachment correctly predicted 73.3% voluntary turnover after Year 1. Organization entry constructs and first year attitudes explained 45% of the variance in organizational commitment and 48.9% of organizational attachment 3 years later. Preliminary evidence suggests mediated causal paths link other aspects of newcomer perceptions, work attitudes, and turnover.     

The Interaction Effects of Leader and Follower Conscientiousness on Person-Supervisor Fit Perceptions and Follower Outcomes: A Cross-Level Moderated Indirect Effects Model

ABSTRACT

The primary purpose of this study is to examine how the cross-level interaction between leader and follower conscientiousness influences person-supervisor (PS) fit perceptions, which in turn impact follower work attitudes and organizational citizenship behavior (OCB). Based on a sample of 1,204 participants in 167 work teams, the results of our cross-level moderated indirect effects model show that highly conscientiousness followers whose leaders also have high levels of conscientiousness experience enhanced perceptions of PS fit which result in higher levels of job satisfaction and OCB and lower levels of intention to quit. The study suggests that high leader conscientiousness serves as a supportive situational cue that motivates followers to more fully express their conscientiousness and act in ways consistent with their conscientiousness.     

Collaboration Technologies Improve Performance and Communication in Air Battle Management

Team communication is critical for Air Battle Management (ABM). In this study, two communication tools (text chat and electronic whiteboard) and two team resource aids (tabular and graphical displays) were introduced during simulated ABM to supplement radio communication. Results showed that combined chat and virtual whiteboard improved team performance, decreased number and duration of radio transmissions, but had mixed effects on workload. In addition, the graphical resource display improved team performance, decreased number and duration of radio transmissions, and reduced workload compared to the tabular display. These findings indicate that collaboration technologies introduced in this experiment may benefit military operations.     

Acting Superior But Actually Inferior?: Correlates and Consequences of Workplace Arrogance

Accounts of arrogant employees abound, yet there is little systematic research on arrogance within organizations. In response to this oversight, this article presents the findings from four studies. In Studies 1 and 2, the authors developed the Workplace Arrogance Scale and found support for its convergent and discriminant validity. In Study 3, the Workplace Arrogance Scale was included as part of a 360-degree performance feedback survey. Results revealed that there was satisfactory agreement between self- and other-ratings of arrogance. The authors also found that arrogance was negatively related to self- and other-rated task performance. Findings from Study 4 suggested that arrogance is negatively related to cognitive ability and self-esteem. The authors conclude by discussing the theoretical and practical implications of these findings.     

Brief Report- Adults' Freely Produced Emotion Labels for Babies' Spontaneous Facial Expressions

English-speaking Canadian, Cantonese-speaking Hong Kong Chinese, and Japanese speaking Japanese adults were shown 13 still photographs of the facial expressions of Chinese babies subjected to various emotion-elicitation procedures. Some respondents were asked to give an emotion label of their choice for each photograph, others to judge its pleasant-unpleasant quality. Only facial expressions taken during the “happy”; condition showed agreement by a majority across all three cultural samples on a specific basic emotion. Agreement on the pleasant-unpleasant quality of the baby's expressions was higher, but still varied with culture.     

The within-subjects design in the study of facial expressions

The common within-subjects design of studies on the recognition of emotion from facial expressions allows the judgement of one face to be influenced by previous faces, thus introducing the potential for artefacts. The present study (N=344) showed that the canonical “disgust face” was judged as disgusted, provided that the preceding set of faces included “anger expressions”, but was judged as angry when the preceding set of faces excluded anger but instead included persons who looked sad or about to be sick. Chinese observers showed lower recognition of the “disgust face” than did American observers. Chinese observers also showed lower recognition of the “fear face” when responding in Chinese than in English.     

Digital Drift and the “Sense of Injustice”: Counter-Productive Policing of Youth Cybercrime

ABSTRACT

Over the past several decades, criminological scholarship has increasingly focused on the problem of cybercrime including technology-enabled offending. Theoretical developments that account for these offences have not grown in tandem, leading to questions as to the nature of cybercriminality relative to traditional forms of offending. Recently, Goldsmith and Brewer proposed the conceptual framework of digital drift, extending elements of Matza’s original theories to the virtual environment. While making a useful contribution to the theorization of cybercrime, we argue that further elements of Matza’s original work also warrant consideration. In particular, we acknowledge the role of policing and the criminal justice system in affecting offender perceptions and decision-making. As such, this article extends the theorizing around digital drift to incorporate the ways that offender views are shaped in reaction to the law enforcement and industry responses to cybercrime. The implications of this extension are discussed in depth.
