降压达标治疗中的个体化原则与优化治疗

为了提高高血压患者的降压达标率、最大程度地降低靶器官损伤,一方面应强化生活方式的改变,包括戒烟限酒、低盐饮食、减轻体重和适量运动,另一方面,由于原发性高血压的发病是由多种复杂因素的不同组合引起,应根据不同个体的高血压发病机制及病因的差异,在指南的指导下,应用不同种类抗高血压药物(单用或联合用药),采用针对个体的优化治疗,才能更有效地使降压治疗达标。     

Prediction of longevity of volunteer service: a basic alternative proposal

A problem for many organizations is the low continuity of volunteers. Diverse theoretical models have been developed to explain sustained volunteerism, but most of these models have focused on the study of welfare volunteerism and not have verified whether their results could be generalized to other types of volunteerism. In this study, we propose a basic model to explain sustained volunteerism in any type of volunteerism. The aim of this study is to examine this basic model empirically in a sample of socio-assistential volunteers and in a sample of environmental volunteers. For this purpose, 290 volunteers completed a questionnaire and subsequently, two telephone follow-ups were carried out to determine whether the volunteers remained in the NGO one year later. The results show that the basic model offers an acceptable explanation of sustained volunteerism in the two types of volunteer samples studied, but it accounted for a low percentage of variance of the duration of service in both samples. Various relevant implications for the practical management of volunteerism in organizations are derived from theses findings.     

认知行为干预防治个体晕船发生的实验研究

从心理学角度探讨晕船防治的有效方法,以降低出海作业人员的晕船发生率。本研究对某部门出海作业人员进行了认知行为干预的实验对照研究,研究对象先在陆地模拟抗晕训练,后出海航行进行检验;两组陆地训练内容均有平衡功能适应性训练,实验组外加认知行为干预。研究采用Graybiel晕动病症状和体征的评分标准进行晕船反应评估。结果表明：海训中实验组的晕船发生率、Graybiel平均年导分及其等级均显著低于对照组（P〈0．05）,初步显示：认知行为干预对晕船防治有一定效用,可作为综合防治晕船的辅助手段。     

ERPs associated with visual duration discriminations in prefrontal and parietal cortex

An event-related potentials (ERP) study was undertaken to examine the role of prefrontal and parietal association cortices on selective attention and short-term memory functions in a duration discrimination task. Subjects performed better when discriminating the first stimulus relative to the second and not the reverse. Two contingent negative variations (CNV) were obtained for each stimulus duration at prefrontal regions, as well as two P300s at parietal regions. The CNV(S1) component recorded during the first stimulus (S1) appeared to be involved in selective attention at bilateral sites, while the P300(S1) component in the left hemisphere may be implicated in retaining it. The CNV(S2) wave, displayed during the second stimulus (S2), at bilateral sites and the right-sided P300(S2) wave seem to be implicated in working memory. The results indicate that recorded activity at prefrontal and parietal association cortices is tightly linked to task parameters and behavioral performances.     

One, two, three, four, nothing more: an investigation of the conceptual sources of the verbal counting principles

Since the publication of [Gelman, R., & Gallistel, C. R. (1978). The child's understanding of number. Cambridge, MA: Harvard University Press.] seminal work on the development of verbal counting as a representation of number, the nature of the ontogenetic sources of the verbal counting principles has been intensely debated. The present experiments explore proposals according to which the verbal counting principles are acquired by mapping numerals in the count list onto systems of numerical representation for which there is evidence in infancy, namely, analog magnitudes, parallel individuation, and set-based quantification. By asking 3- and 4-year-olds to estimate the number of elements in sets without counting, we investigate whether the numerals that are assigned cardinal meaning as part of the acquisition process display the signatures of what we call "enriched parallel individuation" (which combines properties of parallel individuation and of set-based quantification) or analog magnitudes. Two experiments demonstrate that while "one" to "four" are mapped onto core representations of small sets prior to the acquisition of the counting principles, numerals beyond "four" are only mapped onto analog magnitudes about six months after the acquisition of the counting principles. Moreover, we show that children's numerical estimates of sets from 1 to 4 elements fail to show the signature of numeral use based on analog magnitudes - namely, scalar variability. We conclude that, while representations of small sets provided by parallel individuation, enriched by the resources of set-based quantification are recruited in the acquisition process to provide the first numerical meanings for "one" to "four", analog magnitudes play no role in this process.     

Take care! The evaluation of a team-based burnout intervention program for oncology care providers

In this quasi-experimental study among staff of 29 oncology wards, the authors evaluated the effects of a team-based burnout intervention program combining a staff support group with a participatory action research approach. Nine wards were randomly selected to participate in the program. Before the program started (Time 1), directly after the program ended (Time 2), and 6 months later (Time 3), study participants filled out a questionnaire on their work situation and well-being. Results of multilevel analyses showed that staff in the experimental wards experienced significantly less emotional exhaustion at both Time 2 and Time 3 and less depersonalization at Time 2, compared with the control wards. Moreover, changes in burnout levels were significantly related to changes in the perception of job characteristics over time.     

Pronouns and quantifier-scope in English

This paper is truly a joint effort and it could not have been written without the contribution of both authors. Garson, though, deserves credit (or blame) for first seeing the need for two kinds of quantifier scope, and also for devising essentials of the positive theory.     

Two Contrasting Explanations of Involvement Violations:

Among the theories that address the impact of variations in immediacy behaviors during ongoing interactions are expectancy violations (EV) and discrepancy arousal (DA) theories. This study of the effects of violations of expectations on arousal, reciprocity, and compensation in the medical practitioner-patient relationship contrasts EV predictions with DA predictions. EV theory predicts that given a communicator with high reward valence, high and very high involvement (including touch and close proximity) should be met with reciprocation (increased involvement), and low and very low involvement should be met with compensation (increased involvement). DA theory predicts compensating very high involvement with decreased involvement, reciprocating high involvement with increased involvement, compensating low involvement with increased involvement, and reciprocating very low involvement, with decreased involvement. Results supported neither theory as all involvement changes were met with reciprocity. Additionally, although all violations/discrepancies were followed by changes in arousal, size of arousal change was not monotonically related to size of involvement change, as predicted by DA theory. Finally, although positive versus negative emotional experiences were not related to physiological indicators of arousal change, size of involvement change was directly related to the experience of positive and negative emotions. Thus, it appears that involvement change size directly predicts emotional experience and is not mediated by arousal change.     

Visual and phonological codes in letter and word recognition: Evidence from incremental priming

Critical issues in letter and word priming were investigated using the novel incremental priming technique . This technique adds a parametric manipulation of prime duration (or prime intensity) to the traditional design of a fast masked priming study. By doing so, additional information on the time course and nature of priming effects can be obtained. In Experiment 1, cross-case letter priming (a-A) was investigated in both alphabetic decision (letter/non-letter classification) and letter naming. In Experiment 2, cross-case word priming was investigated in lexical decision and naming. Whereas letter priming in alphabetic decision was most strongly determined by visual overlap between prime and target, word priming in lexical decision was facilitated by both orthographic and phonological information. Orthographic activation was stronger and occurred earlier than phonological activation. In letter and word naming, in contrast, priming effects were most strongly determined by phonological/articulatory information. Differences and similarities between letter and word recognition are discussed in the light of the incremental priming data.
