Information theory,evolutionary computation,and Dembski’s “complex specified information”

Intelligent design advocate William Dembski has introduced a measure of information called “complex specified information”, or CSI. He claims that CSI is a reliable marker of design by intelligent agents. He puts forth a “Law of Conservation of Information” which states that chance and natural laws are incapable of generating CSI. In particular, CSI cannot be generated by evolutionary computation. Dembski asserts that CSI is present in intelligent causes and in the flagellum of Escherichia coli, and concludes that neither have natural explanations. In this paper, we examine Dembski’s claims, point out significant errors in his reasoning, and conclude that there is no reason to accept his assertions.     

The Challenge of Inter‐faith Relations for the Christian Conference of Asia

Asia is the cradle of many religions, and religious diversity is the hallmark of most Asian societies. Religiosity runs deep in the Asian outlook on life. Why then, one would ask, did the Christian Conference of Asia (CCA) not have visible and structured inter‐faith dialogues as one of its programme priorities? This article examines the reasons why it would have been difficult and even inappropriate for the CCA to initiate a robust dialogue programme in the context in which it was founded. However, CCA did respond to the inter‐faith reality by animating theological and missiological reflections that took Asian social realities and religious pluralism as the contexts of these reflections. Today, religions are increasingly entering the public, and especially the political, arena. There is an increase in religious intolerance and militancy in a number of Asian countries. These have resulted in CCA paying more focused attention to inter‐faith relations and religious plurality.     

A Quasi-Experimental Evaluation of the Effects of Police Body-Worn Cameras (BWCs) on Response-to-Resistance in a Large Metropolitan Police Department

The current study provides a statistically rigorous program evaluation of the impact of police body-worn cameras (BWCs) on police response-to-resistance (e.g., use of force). Results indicate that BWC officers’ mean frequency of response-to-resistance decreased by 8.4% from the 12 months pre-BWC implementation to the 12 months post-BWC implementation compared with a 3.4% increase observed for the matched sample of non-BWC officers. Police departments should consider adopting BWCs alongside other strategies to reduce police response-to-resistance, and to improve transparency and accountability. Study limitations and directions for future research are also discussed.     

Worldviews and individual vulnerability to suicide: The role of social axioms

Research investigating the role of generalized beliefs about the world or worldviews is relatively scarce in the suicide literature. Two studies, using Hong Kong Chinese samples, examined how worldviews, as assessed by the Social Axioms Survey (SAS), were linked with individual vulnerability to suicide. In Study 1, we investigated the relationships of social axioms with various suicide indicators in cognitive, emotional and interpersonal domains, viz., suicidal ideation, negative self‐esteem, psychache, burdensomeness and thwarted belongingness. Results from canonical correlation analysis showed that beliefs along the axiom dimensions of social cynicism, reward for application, and social complexity were linked to these suicide indicators. In Study 2, we tested the interplay of worldviews and personality traits in the prediction of suicidal thoughts. Hierarchical regression results demonstrated the predictive power of social axioms over and above that provided by the Big Five personality dimensions. Moreover, a significant interaction was observed between belief in reward for application and negative life events in predicting suicidal ideation, showing that reward for application buffered the effect of negative life events on suicidal ideation. Based on these results, we discussed the significance of worldviews as a consideration in suicide research and their implications for clinical assessment and intervention.

Expressions of emotional distress in active duty military personnel with mild traumatic brain injury: A qualitative content analysis

Service members (SMs) who sustain traumatic brain injury (TBI) during deployment have increased risk for mental health issues. Mental health treatment can be challenging in military settings where treatment seeking is often stigmatized. Adequate care relies on accurate interpretations of SMs’ verbal accounts of distress, but little is known about how SMs, embedded in a culture that values resilience and self-reliance, relay emotional distress. We performed qualitative analyses of recordings from a telephone-based intervention with 25 SMs who sustained deployment-related mild TBI (mTBI) to elucidate thematic and dialectal patterns. Consistent with our expectations, SMs rarely used explicit depressive terms while discussing their emotional distress. More prevalent was language suggestive of an overarching theme of loss of control, whereby SMs’ stress, anxiety, and anger were often attributable to SMs’ perceptions that they had incomplete jurisdiction over their own lives. This study may help mental health providers improve engagements with SMs and Veterans, preventing misunderstandings and even improper diagnoses or referrals that could result from a strict reliance on the more customary expressions of distress.     

Feedlot veterinarians' moral and instrumental beliefs regarding antimicrobial use in feedlot cattle

This cross‐sectional survey research study examined the role moral beliefs play in predicting behavioural beliefs and attitudes and the role that subjective norms play in predicting moral beliefs. Using a self‐administered questionnaire, one hundred and three feedlot veterinarians completed measures of behavioural beliefs, referent others, perceived constraints and moral beliefs regarding recommendations to use antimicrobials in four situations (i.e. acutely sick cattle, chronically sick cattle, at‐risk cattle and high‐risk cattle). Regression analysis and F‐tests indicate moral beliefs as contributing significant increases in R² to models predicting behavioural beliefs regarding antimicrobial use in each situation. In addition, subjective norms contribute a significant increase in R² in models predicting moral beliefs in each of the four situations. The results indicate the effects of moral beliefs on behavioural beliefs are somewhat contingent on the condition; that is the level of risk associated with treating cattle with antimicrobials, the level of risk of not doing so, and the effectiveness of the antimicrobial in situations such as acute illness or being at‐risk of illness.

Linking family dysfunction to suicidal ideation: Mediating roles of self-views and world-views

Research on suicide has documented various factors predicting suicidal ideation. The present study focused on the pathways emanating from one of the external, environmental forces (i.e. family dysfunction) through internal responses (beliefs about oneself and about the world), to suicidal ideation among Hong Kong Chinese. Using structural equation modelling, we tested the mediating roles of depressive self-views (including stress perception, depressive cognition and negative self-esteem) as well as two dimensions of social axioms (social cynicism and negative reward for application). Multi-group analysis showed that the mediation model was invariant across both males and females. Being socialized into a problematic family of origin affected multiple aspects of one's assessments of both oneself and one's world which, in turn, lead to greater suicidal ideation. Our findings provide important implications for assessing suicidal risk and guiding interventions in clinical treatment.     

The Attitude–Behavior Relationship: A Test of Three Models of the Moderating Role of Behavioral Difficulty1

The moderating role of behavioral difficulty in the attitude–behavior relationship remains a controversial topic in social psychology. Previous research has been unclear in establishing the direction of this moderation, and 3 theoretical models have been proposed: positive and linear; negative and monotonic; and quadratic. The current paper reports analyses of survey data from 5 different studies that afford measures of environmental attitude, behavior, and behavioral difficulty. Across these studies, we found a substantial and unmoderated average attitude–behavior relationship (r = .54). The data also show that the attitude–behavior relationship is weaker for extremely easy and extremely difficult behaviors. Additional analyses suggest, however, that these reductions in the attitude–behavior relationship are probably because of methodological reasons.     

Cognitive reference points in judgments of symbolic magnitude

Research on speeded symbolic magnitude comparisons indicates that decisions are made more quickly when the magnitudes of the stimuli being compared are relatively close to an explicit or implicit reference point. Alternative explanations of this phenomenon are tested by seeking similar effects in nonspeeded rating tasks. In accord with the predictions of discriminability models, rated magnitude differences between stimuli in the vicinity of a reference point are expanded relative to differences between stimuli far from it. The inferred locations of cities along a west-east axis varies systematically depending on which coast, Pacific or Atlantic, is specified as the reference point. Scales derived from the rating data are correlated with the pattern of reaction times obtained in a comparable speeded comparison task. In addition, the distance between the cities nearest the locale of our subjects is subjectively stretched. Reference point effects are also observed when the form of the comparative specifies an implicit reference point at either end of a continuum of subjective size; however, these effects are very small and do not clearly support a discriminability interpretation. Stronger evidence for discriminability effects is obtained when an explicit reference point is established at an arbitrary size value. An implicit scaling model, related to range-frequency theory, is proposed to account for the influence of reference points on relative discriminability of stimulus magnitudes. The implicit scaling model is used to develop an account of how symbolic magnitudes may be learned and of how habitual reference points can produce asymmetries in distance judgments.
