大学生神经质人格、手机网络服务偏好与手机网络过度使用的关系*

采用问卷法,以1488名大学生为被试,探讨了大学生神经质人格、手机网络服务使用偏好与手机网络过度使用行为的关系。结果表明：（1）大学生对手机网络服务的偏好依次是：信息服务、娱乐服务、社交服务和交易服务;（2）大学生神经质人格与手机网络服务偏好和手机网络过度使用有显著正相关,信息服务和娱乐服务与手机网络过度使用有显著正相关;（3）大学生神经质人格、信息服务和娱乐服务对手机网络过度使用具有直接正向预测作用;（4）神经质人格通过信息服务和娱乐服务间接影响大学生的手机网络过度使用,信息服务和娱乐服务在二者间起到部分中介作用。可以通过塑造大学生的积极人格,培养积极大学生的新媒体素养,有效抑制大学生对手机网络的过度使用行为。     

冠心病诊治中的过度医疗

近年来,过度医疗问题引起了医学伦理学界的普遍关注。过度医疗是一个经济现象,同时也是一个伦理问题．确切的说是一个医学一社会问题。结合冠心病过度医疗的特点,从医学伦理学角度剖析冠心病过度医疗的原因,并提出了医者、患者、医疗机构和社会针对冠心病过度医疗应采取的措施。     

大医院过度扩张与医疗行业的社会使命

大医院过度扩张已是不争的事实,加速了医疗资源的不合理分配,是造成看病贵的重要原因。医院自身有责任,主管部门与权威媒体实际上在鼓励大医院过度扩张。是医院社会使命重要,还是过度扩张重要,这是培育职业精神、践行社会使命必须做出的艰难抉择。     

Implementation of automatic speed enforcement: Covariation with young drivers’ reported speeding behaviour and motivations

IntroductionSpeeding represents one of the main causes of road crashes worldwide, particularly among young drivers who are over-represented in road-crash statistics. For promoting road safety in France, an automatic speed enforcement (ASE) system was introduced late 2002.ObjectiveIn order to examine its efficiency on speeding and its motivations, we compared young drivers’ intentions and beliefs about speeding between the introduction of ASE (T1) and its completion in 2005 (T2) via a large survey based on the extended Theory of Planned Behaviour (TPB). We assumed the introduction of the ASE would covariate with a reduction in intention to speeding between T1 and T2 and a change in the extended TPB factors according to gender and driving experience.MethodOne thousand one hundred and ninety-two young participants (49.7% men) divided into novice, beginner, and more-experienced drivers filled in a questionnaire based on the extended TPB about their driving behaviour and history at T1 and 24 months later (T2).ResultsMen, beginner and more-experienced drivers expressed more intention to speeding within the next 12 months at T1 and showed a higher decrease in intention between T1 and T2 as compared to women and novice drivers. The extended TPB accounted for 59% of the variance in the decrease of the intention to speeding. Its main predictors were: lower perceived behavioural control over speeding, less social pressure, lower perceived similarity with the prototypical deviant driver, and higher comparative optimism. Secondly, slightly more positive behavioural beliefs and more negative outcome evaluations predicted this decrease.ConclusionPractical implications of the findings for road safety are discussed.     

Do men with excessive alcohol consumption and social stability have an addictive personality?

The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".     

如何降低ICU费用——规范ICU的建设和管理

ICU收费高的主要症结在于ICU的建设和管理需要规范化,包括在中国制定ICU的收治和转出指征规范,减少过度医疗和延迟医疗;积极配备ICU人力资源,提高监护质量,培训ICU专业医师上岗,掌握并运用专业知识施救,保证治疗的恰当性。允许恰当的家属陪护,对患者给予情感支持,或可降低镇静药物等的使用,缩短住院日;对于脑死亡、植物状态以及癌症晚期或其他晚期疾病的临终患者,提倡放弃治疗,避免无益救治造成卫生资源的浪费,对家属造成巨大的精神压力和经济负担。但是医生主动放弃治疗的决定尚需要政策的支持和法律的保障。     

提倡“理性医疗”

“理性医疗”是对疾病进行科学、客观地综合分析,由此筛选出一个理性的处置方案的医疗过程。“理性医疗”不但有利于社会,有利于医患双方,更符合自然科学的规律,同时,对传统的伦理学观念也是一种补充与完善。“理性医疗”的实现需要医患双方的共同协作。

The Relative Specificity of Excessive Reassurance-Seeking to Depressive Symptoms and Diagnoses Among Clinical Samples of Adults and Youth

In addition to playing a role in the deterioration of depressed people's interpersonal environment, excessive reassurance-seeking may be implicated as a vulnerability factor for depression. If so, excessive reassurance-seeking should display relative specificity to depression versus other forms of psychopathology. Two studies of psychiatric inpatients (Study 1 on adults and Study 2 on children) tested this possibility. In Study 1 a Depressed group obtained higher reassurance-seeking scores than an Other Disorders group did. Similar findings were obtained in Study 2, such that depressed youth reported higher reassurance-seeking than nondepressed youth. Hence, these two studies of psychiatric inpatients provided reasonable support for the specificity of excessive reassurance-seeking to depression as compared to other forms of psychopathology.
