Two studies used a target detection task to examine temperament-related attentional biases toward and away from significant stimuli. Pretarget cues were used to orient attention to locations carrying a positive incentive value (where points could be gained) or a negative value (where points could be lost). Under both involuntary and voluntary conditions, extraverts were slow to shift attention away from positive locations, whereas introverts were slow to shift from negative locations. These biases were enhanced on trials following negative feedback and tended to be strongest in Ss high in Neuroticism. The findings support models proposing that Extraversion reflects the combined activity of positive (strongest in extraverts) and negative (strongest in introverts) incentive motivational processes. They further suggest that incentive processes regulate the ability to shift attention away from, rather than toward, significant stimuli.

This article discusses the various aspects of designing a system for eliciting knowledge about language from informants. For each design aspect, various options for implementation are presented, along with their pros, cons, and repercussions for other parts of the knowledge elicitation system. A running example throughout the text is taken from the paradigmatic morphology elicitation module of a system called Boas, which elicits knowledge to support a machine translation system. The main point of the article is an argument about the necessity to analyze the design choice space for complex natural language processing (NLP) systems early, comprehensively, and overtly.  相似文献

This paper analyzes the structure and meaning of text elements cross-linguistically and discusses how that information can be elicited from people in a way that is directly useful for NLP applications. We describe a recently developed computer-based linguistic knowledge elicitation system that initiates a new paradigm of knowledge acquisition methodologies for NLP. In particular, we describe the natural language phenomena the system seeks to cover, the approach to knowledge elicitation and its rationale, the elicitation modules themselves, and broader implications of this work.  相似文献

Nurses (N := 179; Study 1) and managers (N = 154; Study 2) participated in 2 panel studies examining the relationship among prior commitment (affective and continuance commitment and perceived organizational support), coping strategies, and survivors' attitudes and perceptions during and following downsizing. In Study 1, perceived organizational support was significantly positively related to control-oriented coping, job satisfaction, and intention to remain and negatively related to perceived job insecurity and burnout 2 years later. In Study 2, coping mediated the relationship between the prior commitment variables and job alienation, health symptoms, and burnout following the downsizing. Control-oriented coping was associated with elevated levels of health symptoms and burnout following the downsizing, suggesting that control-oriented coping may have positive effects in the short term but potentially harmful effects in the long term.

Multiam star polyesters were synthesized by growing poly(ε‐caprolactone) (PCL) arms from hyperbranched polyesters cores of different molecular weight and used as polymeric modifiers in UV‐curable cationic formulations based on a biscycloaliphatic epoxy resin. The effect of the multiarm stars on the curing kinetics has been investigated by real‐time FTIR. The thermal‐mechanical properties of the photocured thermosets have been studied with calorimetry and dynamomechanical and thermogravimetric analysis. Impact strength tests have been performed to assess their effect on the toughness of the cured materials. An accelerative effect of these modifiers has been observed as a consequence of the participation of the hydroxyl groups of the modifiers in the cationic curing of the epoxy resin. A modest increase in toughness accompanied by a decrease in the glass transition are observed, as a consequence of the incorporation of the modifiers into the network structure, leading to homogeneous, in situ reinforced materials. © 2013 Wiley Periodicals, Inc.

Urban and rural areas may have different levels of environmental contamination and different potential sources of exposure. Many metals, i.e., arsenic (As), lead (Pb), and mercury (Hg), have well-documented negative neurological effects, and the developing fetus and young children are particularly at risk. Using a database of mother and child pairs, three areas were identified: a rural area with no increased prevalence of mental retardation and developmental delay (MR/DD) (Area A), and a rural area (Area B) and an urban area (Area C) with significantly higher prevalence of MR/DD in children as compared to the state-wide average. Areas were mapped and surface soil samples were collected from nodes of a uniform grid. Samples were analyzed for As, barium (Ba), beryllium (Be), chromium (Cr), copper (Cu), Pb, manganese (Mn), nickel (Ni), and Hg concentrations and for soil toxicity, and correlated to identify potential common sources. ArcGIS® was used to determine distances between sample locations and industrial facilities, which were correlated with both metal concentrations and soil toxicity. Results indicated that all metal concentrations (except Be and Hg) in Area C were significantly greater than those in Areas A and B (p ≤ 0.0001) and that Area C had fewer correlations between metals suggesting more varied sources of metals than in rural areas. Area C also had a large number of facilities whose distances were significantly correlated with metals, particularly Cr (maximum r = 0.33; p = 0.0002), and with soil toxicity (maximum r = 0.25; p = 0.007) over a large spatial scale. Arsenic was not associated with distance to any facility and may have a different anthropogenic, or natural source. In contrast to Area C, both rural areas had lower concentrations of metals, lower soil toxicity, and a small number of facilities with significant associations between distance and soil metals.  相似文献

Attempted to define interpersonal warmth in behavioral terms by determining the association between global ratings of warmth and objective measures of specific behavioral cues. 18 male and 18 female undergraduates made ratings of the interpersonal warmth of 16 other students from videotaped interviews. These ratings were then related to measures of the interviewees' (a) frequency of verbal expression of positive feelings toward self, others, and surroundings; (b) speech rate; and (c) frequency of smiling and of head and body movement. A multiple correlation of .89 indicated that the 7 behavioral cues accounted for 79% of the variance of the warmth ratings. Those cues most closely related to warmth ratings were (a) frequency of smiling, the single best predictor; and (b) number of positive statements about other people. A factor analysis identified 2 factors, the 1st an evaluative one of positive response to others and the 2nd an activity level factor. Warmth is tentatively defined as positive response to others, actively conveyed. (41 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Presents impressions based on 5 days' observation of the clinical activities of Joseph Wolpe and Arnold Lazarus at the Eastern Pennsylvania Psychiatric Institute: (1) behavior therapists now treat a wider range of patients and use a greater variety of treatment methods than before; (2) treatment is becoming longer and more complicated, with concomitant lowering of success rates; (3) clinical inference is essential in diagnosis, hierarchy selection, patient management, and ongoing evaluation; and (4) elements of suggestion in the patient-therapist reltionship may play a powerful role in treatment. Implications of these impressions for research and clinical training are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
