影响部队汽车驾驶员心身健康水平和行车安全的相关因素研究

对部队汽车驾驶员203名的心身健康和行车安全的相关因素研究表明:驾驶员可发生心身障碍,尤其眼和耳、呼吸系统,骨胳肌肉系统及抑郁等为著。其影响因素,主要有负性精神紧张总值(-Lcu)、个性的精神质、神经质、掩饰性、内向倾向、开车公里数、开车年限及精神疾病家族史。某些心身问题、神经质、掩饰性较高、年龄偏大、开车公里数多及开车年限长等与事故差错的发生有关。     

Global environmental change: preventive measures to reduce the impact on human health

Awareness of the magnitude of worldwide climate change and theloss of biological diversity that may occur as the result ofpresent human activities is increasing. However, much needsto be done to reverse current trends and prevent unprecedentedglobal environmental changes which are expected to produce irreversibleresults, and to have profound implications for the health ofindividuals. This paper briefly reviews what is known aboutthe global environmental changes that are taking place and theirpredicted impact on human health. Some of the preventive measuresand activities in which public health professionals need toassume leadership roles in the critical years ahead are discussed.Our hope is to enliven a much needed dialogue among health professionalson the crucial issue of environmental survival in which preventionmay be the only viable solution.     

Malignant Warthin''s tumour: a case study

Malignant transformation of a benign Warthin's tumour (adenolymphoma) is extremely rare. The light microscopic and ultrastructural features of an adenocarcinoma arising in a Warthin's tumour in the parotid gland are described. Light microscopy demonstrated a transition zone from the benign to the malignant component, and the malignant cells revealed oncocytic features by both light- and electronmicroscopy.

Diversity in Clinical Psychology

Clinical psychology is not as diverse as society, and the generalizability of clinical psychology to diverse groups has largely been untested. Some progress has been made in increasing the number of ethnic minorities receiving PhD degrees in clinical psychology and in increasing ethnic minority representation in clinical trials. Nevertheless, clinical psychologists and clinical psychology research are not diverse. A stages of change model may be useful in motivating clinical psychologists to diversify. A future scenario involving inertia and a second involving change are offered.     

Expanding Our Strategies to Study the Process of Change

The conceptual and methodological framework proposed by Doss (this issue) makes valuable suggestions for strategic choices in future research. This commentary addresses conceptual and terminological distinctions adopted by Doss, as well as his criticism of add-on/ dismantling studies. We also suggest research topics and methodological developments that could be integrated in Doss's framework to further expand understanding of therapeutic change.
