基于自我意识的Agent通信语言研究

Agent间的通信目的是不断完善其自我意识,Agent间的通信内容是Agent对其自我意识的解释,Agent间的通信过程是Agent在其自我意识上的推理。在研究经典Agent通信语言的基础上,结合知识类别、自我意识、语气等相关研究成果,以能描述语义的互表性、模糊性、动态性和自我意识性的动态本体描述语言作为通信内容的表示工具,设计了一个基于自我意识的Agent通信语言,给出了该语言的消息结构和语用词,并通过实例来解释Agent间的通信过程是Agent在其自我意识上的推理。     

从意中之象到意中之境——孟浩然《宿建德江》解读

《宿建德江》是孟浩然诗作的山水名篇,该诗的“象”都是意中之象,是经过诗人严格地主观选择才进入诗境中的。它们很好地传达出了诗人的思乡之愁、羁旅之苦、失意之悲、孤独之情。这些具有深厚联系的意中之象组合在一起,形成该诗的意中之境。意中之境是对意中之象的一种巨大超越,能开拓出无限的审美空间。通过对该诗的意中之境进行分析,可以见出诗人有浓厚的悲剧意识。因此,《宿建德江》也是一首悲诗。     

Mood influences on acute smoking responses are independent of nicotine intake and dose expectancy.

Acute responses to smoking are influenced by nicotine and by nonpharmacological factors such as nicotine dose expectancy and sensory effects of smoke inhalation. Because negative mood increases smoking reinforcement, the authors examined whether these effects may be altered by mood context. Smokers (n=200) participated in 2 sessions, negative or positive mood induction, and were randomized to 1 of 5 groups. Four groups comprised the 2×2 balanced placebo design, varying actual (0.6 mg vs. 0.05 mg yield) and expected nicotine dose (expected nicotine vs. denicotinized [denic]) of cigarettes. A fifth group was a no-smoking control. Smoking, versus not smoking, attenuated negative affect, as well as withdrawal and craving. Negative mood increased smoking reinforcement. However, neither actual nor expected nicotine dose had much influence on these responses; even those smokers receiving and expecting a denic cigarette reported attenuated negative affect. A follow-up comparison suggested that the sensory effects of smoke inhalation, but not the simple motor effects of smoking behavior, were responsible. Thus, sensory effects of smoke inhalation had a greater influence on relieving negative affect than actual or expected nicotine intake.

Morbidity of DSM-IV Axis I disorders in patients with noncardiac chest pain: Psychiatric morbidity linked with increased pain and health care utilization.

The present study examined current and lifetime psychiatric morbidity, chest pain, and health care utilization in 229 patients with noncardiac chest pain (NCCP), angina-like pain in the absence of cardiac etiology. Diagnostic interview findings based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) revealed a psychiatrically heterogeneous sample of whom 44% had a current Axis I psychiatric disorder. A total of 41% were diagnosed with a current anxiety disorder, and 13% were diagnosed with a mood disorder. Overall, 75% of patients had an Axis I clinical or subclinical disorder. Lifetime diagnoses of anxiety (55%) and mood disorders (44%) were also prevalent, including major depressive disorder (41%), social phobia (25%), and panic disorder (22%). Patients with an Axis I disorder reported more frequent and more painful chest pain compared with those without an Axis I disorder. Presence of an Axis I disorder was associated with increased life interference and health care utilization. Findings reveal that varied DSM-IV Axis I psychiatric disorders are prevalent among patients with NCCP, and this psychiatric morbidity is associated with a less favorable NCCP presentation. Implications for early identification of psychiatric disorders are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perceived group devaluation, depression, and HIV-risk behavior among Asian gay men.

[Correction Notice: An erratum for this article was reported in Vol 27(3) of Health Psychology (see record 2008-08834-013). In the aforementioned article, the second sentence of the Results portion of the abstract should read: Among participants most attracted to Whites, group devaluation was associated with higher levels of nonprimary partner UAI; but was associated with lower levels of nonprimary partner UAI among those most attracted to non-Whites.] Objective: This study examined depressive mood and HIV-risk behavior in relation to perceived group devaluation and group identity. Design: Cross-sectional survey of 192 Asian gay men. Main Outcome Measures: Depressive mood assessed using the Centers for Epidemiological Studies Depression Scale (CES-D) and self-reported receptive or insertive unprotected anal intercourse (UAI) in the past 3 months. Results: Group devaluation was positively associated with depressive mood. Among participants most attracted to Whites, group devaluation was associated with higher levels of nonprimary partner UAI, among those most attracted to non-Whites. Among participants reporting higher levels of group devaluation, those with more positive personal evaluations of the Asian gay community had lower levels of total UAI compared to those with more negative personal evaluations of the Asian gay community. Conclusions: Results suggest that group devaluation is associated with higher levels of depressive mood among Asian gay men. Asian gay men most attracted to non-Whites or hold more positive evaluations of their group may be buffered from the influence of high perceived group devaluation on UAI.

Moods as spotlights: The influence of mood on accessibility effects.

Three studies explore the manner in which one's mood may affect the use and impact of accessible information on judgments. Specifically, the authors demonstrated that positive and negative moods differentially influence the direction of accessibility effects (assimilation, contrast) by determining whether abstract traits or concrete actor-trait links are primed. Study 1 investigated the impact of positive versus negative mood on the judgmental impact of trait-implying behaviors and found that positive moods lead to assimilation and negative moods to contrast. In Study 2, this effect was replicated in a subliminal priming paradigm. In Study 3, it was demonstrated that the type of information activated by trait-implying behaviors is indeed mood dependent, such that abstract trait information is activated in a positive mood, whereas specific actor-trait links are activated in a negative mood.

Acute effects of qigong exercise on mood and anxiety.

Psychosocial stress may lead to increased rates of anxiety and depression. Aerobic exercise and mind-body therapies are frequently described as having positive effects on psychological well-being by enhancing mood and reducing anxiety. Few studies, however, have investigated the acute psychological effects of qigong exercise. Fifty-nine regular qigong exercisers (mean age 50.8 years) were randomized to a Qigong or Control group. Pre- and postmeasurements were then compared. POMS-Depression, Anger, and Fatigue, and STAI-State Anxiety scores decreased significantly in the Qigong group but not in the Control group. Results thereby suggest that qigong exercise can produce desirable psychological effects, and Qigong exercise may therefore be included among other activities performed to boost resistance to daily stressors.

Maternal mood, video-mediated cognitions, and daily stress during home-based, family interactions.

This article presents an in vivo investigation of maternal negative mood, maternal video-mediated cognitions, and daily stressors in families with young children. Specifically, it was hypothesized that greater levels of maternal depressed, anxious, and hostile mood states immediately prior to a daily, reportedly routine, stressful parent–child interaction would be significantly associated with higher percentages of dysfunctional and lower percentages of functional cognitions. Forty-five mothers of 2- to 5-year-old children participated in this study by rating their mood before being videotaped in a daily routine with their child they reported as recurrent and stressful (e.g., mealtime). Using video-mediated recall (VMR) methodology, mothers were instructed to recall their cognitions upon immediate video review. Results indicated that greater levels of negative mood were associated with a greater percentage of dysfunctional cognitions and a smaller percentage of functional cognitions. Levels of maternal depressed mood were significantly and independently associated with greater rates of dysfunctional and lower rates of functional cognitions. Negative mood states were not consistently associated with the amount of maternal self-reported general irrationality, pointing to the utility of the VMR to elicit maternal cognitions specific to the observed interaction, which may have more implications for clinical intervention than more general irrationality measures. Evaluating maternal mood and using video-mediated maternal cognitions regarding daily family stressors can precipitate clinical interventions meant to reduce family-related stress and potentially improve maternal and child mental health outcomes.
