Exposure,Loss, and Support Predicting the Dimensions of Posttsunami Trauma

This study examined whether exposure, resource loss, and social support predicted the posttsunami trauma of PTSD, depression, negative affect, and physical health problems of the 2004 tsunami survivors. Four hundred sixteen survivors were interviewed in Tamil Nadu (India) 14 months posttsunami. Loss of life followed by loss of property and disaster exposure positively predicted the dimensions of trauma. Survivors having lower social status and income received less material and informational support than their equally affected counterparts, which furthered stress and distress. The survivors’ trauma can be arrested, minimizing the exposure and tangible resource loss, and improving the delivery of social support.     

公共卫生的作用及政府职责

从20世纪人类健康的进步的贡献和2003年非典危机的爆发,都反映了公共卫生的作用,公共卫生投入对国家社会经济发展和政治及宏观经济的稳定具有不可忽视的作用和不可取代的贡献.理论研究和实证研究揭示了政府公共卫生投入与健康指标的关联,政府为全体人民提供基本公共卫生产品的必要性.而政府提供基本公共卫生服务和保障基本公共卫生产品供给的重要前提是确保政府预算对公共卫生的投入,使其对人民健康产生正向的积极促进作用.明确各级政府在公共卫生中的责任,实行分级管理和考核监督机制,是急待研究和解决的问题.进一步加大政府对公共卫生政府投入水平和改善投入机制,是今后强化中国政府公共卫生职责的一个突破口.     

Psychometric Modeling of response speed and accuracy with mixed and conditional regression

Human performance in cognitive testing and experimental psychology is expressed in terms of response speed and accuracy. Data analysis is often limited to either speed or accuracy, and/or to crude summary measures like mean response time (RT) or the percentage correct responses. This paper proposes the use of mixed regression for the psychometric modeling of response speed and accuracy in testing and experiments. Mixed logistic regression of response accuracy extends logistic item response theory modeling to multidimensional models with covariates and interactions. Mixed linear regression of response time extends mixed ANOVA to unbalanced designs with covariates and heterogeneity of variance. Related to mixed regression is conditional regression, which requires no normality assumption, but is limited to unidimensional models. Mixed and conditional methods are both applied to an experimental study of mental rotation. Univariate and bivariate analyzes show how within-subject correlation between response and RT can be distinguished from between-subject correlation, and how latent traits can be detected, given careful item design or content analysis. It is concluded that both response and RT must be recorded in cognitive testing, and that mixed regression is a versatile method for analyzing test data.I am grateful to Rogier Donders for putting his data at my disposal.     

On the function of weak phantasmata in perception: Phenomenological,psychological and neurological clues for the transcendental function of imagination in perception

Weak phantasmata have a decisive and specifically transcendental function in our everyday perception. This paper provides several different arguments for this claim based on evidence from both empirical psychology and phenomenology.I would like to express my gratitude to Bill McKenna for his help with the English text and his critical remarks. This paper was presented in the Cork Roundtable for Philosophy in March 2003, at University College, Cork, and I would like to thank Julia Jansen, Tony O’Connor and the other participants for their constructive critique.     

How Do Trait Dimensions Map onto ADHD Symptom Domains?

Theories of Attention-Deficit/Hyperactivity Disorder (ADHD) implicate dysfunctional regulation mechanisms that have been conceptually grouped into “top-down” control and “bottom-up” affective/reactive processes. This dual-process account can be invoked in relation to temperament or personality traits and may clarify how traits relate to ADHD. Two samples were examined to illuminate developmental effects. The younger sample was 179 youngsters aged 7 to 12 years (113 boys; 107 with ADHD). The older sample was 184 adolescents (109 boys; 87 with ADHD) aged 13 to 18 years. Structural equation models included parent-rated traits, teacher-rated ADHD symptoms, and laboratory-obtained executive functions. A control or “top-down” factor included cognitive control and conscientiousness/effortful control. A second factor labeled affective or “bottom-up” included neuroticism/negative emotionality, agreeableness, and reactive control. In the younger sample, these two factors were differentially and specifically related to inattention and hyperactivity, respectively. However, in the older sample, the first factor was related to inattention and hyperactivity, whereas the second factor was related to hyperactivity. Personality traits appear to map onto ADHD symptoms in a meaningful manner consistent with a dual-process model of temperament and ADHD.

Personal selling and the purchasing function: where do we go from here?

The business-to-business selling function has changed over the years, with more informed and demanding buyers, prompting firms to move toward a more consultative, solution-selling approach. While these changes have been the focus of extensive research in the personal selling and sales management domain, the customer side of the interaction dyad requires more examination. Even within the context of the customer side, insufficient attention has been paid to the purchasing function in business-to-business (B2B) selling research. Given the increased importance in customer organizations of the purchasing function, this article presents a literature review that highlights the purchasing function's personal selling and sales management needs and argues that, as the purchasing function becomes more important and its needs evolve, personal selling and sales strategies also need to evolve. The article highlights areas for future research in this domain.     

INTERPRETATION AND THE ORIGIN OF LIFE

We offer a general definition of interpretation based on a naturalized teleology. The definition tests and extends the biosemiotic paradigm by seeking to provide a philosophically robust resource for investigating the possible role of semiosis (processes of representation and interpretation) in biological systems. We show that our definition provides a way of understanding various possible kinds of misinterpretation, illustrate the definition using examples at the cellular and subcellular level, and test the definition by applying it to a potential counterexample. We explain how we propose to use the definition as a way of asking new questions about what distinguishes life from non‐life and of formulating testable hypotheses within the field of origin‐of‐life research. If the definition leads to fruitful new empirical approaches to the scientific problem of the origin of life, it will help to establish biosemiotics as a legitimate philosophical approach in theoretical biology and will thereby support a theological appropriation of the biosemiotic perspective as the basis of a new theology of nature.     

Predicting the Early Developmental Course of Symptoms of Attention Deficit Hyperactivity Disorder

Data from the National Institute of Child Health and Human Development Study of Early Child Care were examined to test whether: attention deficit/hyperactivity disorder (ADHD) symptoms remain stable from 54 months through early elementary school; behavioral inhibition and attention deficits assessed at 54 months predict ADHD symptoms in elementary school, even after controlling for their temporal stability; and early behavioral inhibition and attention deficits moderate the longitudinal stability in ADHD symptoms. Data were examined using continuous and categorical measures of symptoms. Modest stability in ADHD symptoms from 54 months to third grade was found. Measures of inhibition and inattention predicted later teacher ratings uniquely, but no evidence was found for moderation. Measures of preschool behavioral inhibition also predicted “persistently at risk status” defined by elevated teacher ratings over time. Results are discussed in terms of executive and motivational facets of inhibition that may be related to early signs of ADHD.     

Complexity effects on the children's gambling task

The children's gambling task (CGT [Kerr, A., & Zelazo, P. D. (2004). Development of “Hot” executive function: The children's gambling task. Brain and Cognition, 55, 148–157]) involves integrating information about losses and gains to maximize winnings when selecting cards from two decks. Both cognitive complexity and control (CCC) theory and relational complexity (RC) theory attribute younger children's difficulty to task complexity. In CCC theory, identification of the advantageous deck requires formulation of a higher-order rule so that gains and losses can be considered in contradistinction. According to RC theory, it entails processing the ternary relation linking three variables (deck, magnitude of gain, magnitude of loss). We designed two less complex binary-relational versions in which either loss or gain varied across decks, with the other held constant. The three closely matched versions were administered to 3–5-year-olds. Consistent with complexity explanations, children in all age groups selected cards from the advantageous deck in the binary-relational versions, but only 5-year-olds did so on the ternary-relational CGT.     

Spirituality and Loss: Approaches for Counseling Grieving Adolescents

The death of a loved one has serious implications for adolescent growth and development. The authors review relevant research on the grief process and spirituality in adolescence, and they give a rationale for integrating spirituality into adolescent grief work. By way of a case illustration, they draw implications for counselors’ use of spirituality in addressing adolescent grief.
