We give a detailed account of the Algebraically Closed and Existentially Closed members of the second Lee class B
2 of distributive p-algebras, culminating in an explicit construction of the countable homogeneous universal model of B
2. The axioms of Schmid [7], [8] for the AC and EC members of B
2 are reduced to what we prove to be an irredundant set of axioms. The central tools used in this study are the strong duality of Clark and Davey [3] for B
2 and the method of Clark [2] for constructing AC and EC algebras using a strong duality. Applied to B
2, this method transfers the entire discussion into an equivalent dual category X
2 of Boolean spaces which carry a pair of tightly interacting orderings. The doubly ordered spaces of X
2 prove to be much more readily constructed and analyzed than the corresponding algebras in B

Attributions for dietary failures: problems reported by participants in the Hypertension Prevention Trial 总被引:1,自引:0,他引:1
Assigned participants in the Hypertension Prevention Trial to one of four diets for a period of 3 years: (a) weight loss, (b) reduced sodium, (c) weight loss plus reduced sodium, and (d) reduced sodium plus increased potassium. At 6-month intervals, they reported problems they were having adhering to their diets. Problem attributions were coded along the dimensions of internality, stability, and controllability and were categorized as intrapersonal or extrapersonal. Attributions were found to differ by type of diet and sex of participant. Participants assigned to weight-loss groups were significantly more likely than those assigned to non-weight-loss groups to blame themselves for their problems with adherence, making characterological as opposed to external or situational attributions. Men perceived problems to be more controllable than women. Attributions did not predict weight loss, change in urinary sodium, or change in potassium excretion. 相似文献

Preventing weight gain in adults: a pound of prevention 总被引:3,自引:0,他引:3
This study evaluated the feasibility and effectiveness of a program for weight gain prevention in normal-weight adults. Two hundred nineteen participants were randomized to either weight gain prevention treatment or no treatment for a period of 12 months. Those in the treatment group received monthly newsletters relating to weight management, participated in a financial incentive system, and were offered an optional four-session education course in the sixth month of the program. Results demonstrated high interest in weight gain prevention among individuals who were not objectively overweight. Participation, as measured by return of postcards sent with each newsletter, was approximately 75%. Results after 1 year showed a net weight loss in the group receiving the program of 1.8 lb compared to those in the control group. Eighty-two percent of program participants maintained or lost weight, compared to 56% of the control group. It is concluded that programs for weight gain prevention are feasible in adults and may be more effective than weight loss treatment programs in addressing the problem of community-wide obesity. 相似文献

This paper examines and compares the ways in which intentions of the singular kind (“I intend”) and the plural kind (“we intend”) are subjective. Are intentions of the plural kind ours in the same way intentions of the singular kind are mine? Starting with the singular case, it is argued that “I intend” is subjective in virtue of self-knowledge. Self-knowledge is special in that it is self-identifying, self-validating, self-committing, and self-authorizing. Moving to the plural form, it is argued that in spite of apparent differences, attitudes of the form “we intend” are subjective in the same way. The self-knowledge at work here is plural rather than singular. This supports a plural subject account of collective intentionality. It is argued that the worries sometimes raised in the literature against the metaphysical “spookiness” of plural subjects are due to a fundamental misconception of the way in which attitudes of either kind –singular and plural – are subjective. 相似文献

Visual search for feature targets was employed to investigate whether the mechanisms underlying visual selective attention are modulated by observers’ mood. The effects of induced mood on overall mean reaction times and on changes and repetitions of target-defining features and dimensions across consecutive trials were measured. The results showed that reaction times were significantly slower in the negative than in the positive and neutral mood groups. Furthermore, the results demonstrated that the processing stage that is activated to select visual information in a feature search task is modulated by the observer’s mood. In participants with positive or neutral moods, dimension-specific, but no feature-specific, intertrial transition effects were found, suggesting that these observers based their responses on a salience signal coding the most conspicuous display location. Conversely, intertrial effects in observers in a negative mood were feature-specific in nature, suggesting that these participants accessed the feature identity level before responding. 相似文献

Zusammenfassung Der Zusammenhang zwischen Blickwendung und Lidschlag wurde experimentell untersucht. Als wirksame Faktoren erwiesen sich die Größe der Blickwendung, die Kopfbewegung, die Art der Wahrnehmungsobjekte (Person — Gegenstand) und bei Personen der Grad der Aufmerksamkeitszuwendung. Über alle Versuchsbedingungen hinweg zeigte sich die relative Häufigkeit des Lidschlages bei der Blickwendung als individuell konstant.
The relationship between gaze movement and eye blink under various conditions
Summary The relationship between gaze movement and eye blink was investigated. The angle of eye movement, movement of the head, the type of objects perceived (person-object) and (when persons were viewed) the degree of attention were found to be relevant factors. Under all conditions studied, the relative frequency of blinking during gaze movement was shown to be individually constant.相似文献

Mast MS 《Journal of personality assessment》2005,84(3):287-295
The goal of these series of studies was to introduce a new individual difference construct, interpersonal hierarchy expectation (IHE), and to show that it predicts interpersonal perception. IHE means expecting social interactions and relationships to be hierarchically structured. I developed a self-report questionnaire to measure IHE (IHE Scale [IHES]). In 5 studies, 581 undergraduates took the IHES together with an array of self-report personality measures. Three studies included a measure of hierarchy perception. According to prediction, people who expected interpersonal hierarchies were prone to perceive hierarchies in interactions and relationships. The IHES is an easy to apply, short, self-report measure that might prove useful in personnel training and selection as well as in other studies of personality and social behavior. 相似文献
