社交网站使用能带来社会资本吗?

社交网站旨在维系和发展个体的人际关系网络,而社会资本是个体人际关系中潜在的、可获得的益处或资源,因此社交网站使用和社会资本存在密切关系。然而,有关一般性社交网站使用行为与社会资本关系的研究结果并不一致。针对不同类型使用行为的研究发现,特定类型的社交网站使用行为对特定类型社会资本有积极影响。社交网站中自我表露行为是获取社会资本的一种必要的途径,关系维持行为、资源动员请求行为、隐私保护行为等均是个体获取社会资本的有效行为策略。最后,就社会资本定义、线上线下社会资本存在覆盖等问题进行了探讨。     

The frequency of actions and thoughts scale: development and psychometric validation of a measure of adaptive behaviours and cognitions

This paper describes the development and preliminary psychometric evaluation of an instrument that measures the frequency of adaptive behaviours and cognitions related to therapeutic change during cognitive behavioural therapy (CBT), for symptoms of anxiety and depression. Two studies were conducted. In study one, 661 participants completed an online survey with 28 items targeting adaptive behaviours and cognitions. Exploratory factor analysis performed on part of the sample (n = 451) revealed that a four-factor solution ‘characterised’ the data. This led to the development of a 12-item instrument, the Frequency of Actions and Thoughts Scale (FATS). Confirmatory factor analysis was used to confirm the factor structure of the FATS using the remaining sample (n = 210), which revealed an acceptable model fit. In study two, 125 participants with clinically significant symptoms of anxiety, depression, or both were recruited to an Internet-delivered CBT (iCBT) treatment course. Participants completed the FATS and other measures throughout treatment, after treatment, and at three-month follow-up. Correlations and residual change scores of the FATS and its subscales with measures of anxiety, depression, behavioural activation, and CBT-related skills usage supported the construct validity of the FATS. A significant increase in FATS scores over treatment was also observed. The findings provide preliminary support for the psychometric properties of the FATS, which appears to have utility in research investigating mechanisms of change in CBT.     

多目标追踪中“线索”研究的贡献

多目标追踪范式是探讨动态情景下注意加工过程的成熟技术,其对不同阶段注意线索加工与利用的分析,对深入了解注意的动态信息加工过程具有重要意义。从注意线索的视角述评呈现阶段的内源性线索与外源性线索以及追踪阶段的目标数量动态变化和轨迹线索的研究成果及限制因素,提出多目标线索研究是客体档案理论与视觉索引理论之争的关键。虽然多目标追踪范式为内源性线索、外源性线索的提取与策略等研究提供很多便利,但目前该范式在线索的认知资源分配和加工策略上仍有研究留白,尚需进一步探索。     

A four‐disc version of the Tower of London for clinical use

Three studies are reported on the development of a four‐disc version of the Tower of London test of planning ability. The first (n = 138) involved the selection of items based on rational and empirical criteria to provide a short test of graded difficulty suitable for use with children and clinical populations. The second study (n = 480) checked the properties of the 10‐item test on a new sample and in addition examined the internal consistency and factor structure of the test. The third study (n = 61) examined the test – retest reliability of the test over a period of 1 month. The difficulty level of the test remained relatively stable from sample to sample and was sensitive to linear trend in performance from age 5 years up to 30 years. Total score did not reflect the action of a single underlying construct but rather appeared to index a number of factors. Scores were reasonably stable over the 1‐month period studied, at least for the children's sample employed. The four‐disc version is a promising method of assessing planning in children and adolescents in clinical situations.     

Multi-sentential category mistakes

Magidor (Category Mistakes, 2013, OUP) argued that category mistakes are infelicitous due to presupposition failure. The case for this position is strengthened by the consideration of a previously unnoted category of data, namely multi-sentence discourses in which category mistake phenomenology arises at the end of the last sentence, but arguably due to content contained in a previous sentence. This phenomenon is analysed in terms of the previous sentence giving rise to a presupposition that is shown to be false only in the last sentence.     

Implantologie orale et responsabilité : à propos du choix du dispositif implantaire

Dental implants are medical devices designed to create stable, strong, non-iatrogenic and durable anchors in the maxilla or mandible to which a removable or fixed dental prothesis fits, to replace one or more missing teeth. From the 1970s to 2000, these medical devices experienced changes in shape and materials before a consensus was reached on a type of implant that responded to the standard of care. This raises the question of the medical liability of healthcare professionals who use different implant systems in their practices. The present article proposes to highlight the choice of the dental implant by dental practitioner, its design and the materials used, on the field of the medical liability, through a retrospective study of judicial decisions in France. The “Brånemark-type” endosseous cylindrical-conical screw implant is considered as standard of care in France. The dental surgeon has the possibility to use other types of dental implants when the clinical situation strictly contraindicates the use of cylindrical-conical screw implants. In case of litigation, he must be able to justify his choices.     

Le procès pénal du Mediator® et ses implications concernant les différents ordres de juridiction

The long-awaited judgment issued about the Mediator case by the 31st criminal court of the Tribunal de grande instance de Paris will not be the last one. The public prosecutor, as well as Servier and some of the victims have called for the appeal. Nevertheless, the number of victims reflects the extent of damage caused by this medicine. The complexity of the procedure highlights the specificities of the civil and administrative jurisdictions, as well as the transactional process. The purpose is to study the main points related to this articulation.     

Le contentieux de la régularité externe des décisions rendues par les juridictions ordinales des médecins

In the event of irregular composition of the ordinal jurisdiction or omission of certain compulsory particulars in the decision rendered, the parties may challenge the external regularity of the decision. The pleas based on the contested decisions are formal and procedural defects. If successful, these means result in the annulment of the decision ordering the doctor to be disciplined. These means constitute a separated legal cause and can only be invoked within the time limit for appeal, unless they are of public order.
