Executive coaching enhances goal attainment,resilience and workplace well-being: a randomised controlled study

In a randomised controlled study, 41 executives in a public health agency received 360-degree feedback, a half-day leadership workshop, and four individual coaching sessions over 10 weeks. The coaching used a cognitive-behavioural solution-focused approach. Quantitative and qualitative measures were taken. This is the first published randomised controlled study in which coaching was conducted by professional executive coaches external to the organisation. Compared to controls, coaching enhanced goal attainment, increased resilience and workplace well-being and reduced depression and stress. Qualitative responses indicated participants found coaching helped increase self-confidence and personal insight, build management skills and helped participants deal with organisational change. Findings indicate that short-term coaching can be effective, and that evidence-based executive coaching can be valuable as an applied positive psychology in helping people deal with the uncertainly and challenges inherent in organisational change. Practical impactions are discussed and recommendations are made for the effective measurement of coaching outcomes.     

Ab initio study of Heusler alloys Co2XY (X = Cr,Mn, Fe; Y = Al,Ga) under high pressure

The structural, electronic, and magnetic properties of ferromagnetic Heusler alloys Co₂XY (X?=?Cr, Mn, Fe; Y?=?Al, Ga) have been investigated by means of the all-electron full-potential linearized augmented plane wave method within the generalized gradient approximation for the exchange and correlation potential. The main focus of this study is to elaborate the changes brought about in the electronic and the magnetic properties by applied pressure. The calculated total spin magnetic moments of all the compounds are found to be in good agreement with experiments. Out of these compounds, Co₂CrAl is found to be perfectly half-metallic (HM) and the other compounds are found to be nearly HM. Thus the HM to metal transition was observed at 75?GPa pressure for Co₂CrAl and the nearly half-metal to half-metal transition was observed at 40?GPa and 18?GPa for Co₂CrGa and Co₂MnAl, respectively, while no transition is observed in other compounds under investigation. It can be clearly seen that pressure affects the minority spin states rather than the majority states, leading to a slight reconstruction of the minority spin states with a shift in the Fermi level driving the above-mentioned transition.     

Impact of organ transplantation in heart,lung and liver recipients: Assessment of positive life changes

Objective: The majority of psychological studies with organ transplant recipients have examined negative psychological effects. This study aimed to further investigate the positive effects of organ transplantation and to construct a specific measurement instrument.

Design: The initial pool of 14 items for the Positive Effects of Transplant Scale (PETS) was derived from organ recipient interviews. A cross-sectional postal study included 87 heart, 46 lung and 193 liver transplant recipients. The PETS was subjected to principal components analysis (PCA) using varimax rotation, and associations with other measures investigated.

Main outcome measures: PETS and an open-ended item about positive effects.

Results: Coding of the open-ended item revealed that the majority of recipients attributed positive life changes to the transplant experience. PCA of the PETS indicated three factors that accounted for 58.82% of the variance. The 12-item questionnaire assesses improvements in: (1) life philosophy, (2) gratitude and (3) health. The total PETS scores exhibited adequate internal consistency and validity.

Discussion: Most transplant patients report positive psychological effects, which suggests this may be an understudied area. The initial development of an assessment tool provides researchers and clinicians a way to assess the degree and nature of these life changes.     

Prosodic boundaries, comma rules, and brain responses: the closure positive shift in ERPs as a universal marker for prosodic phrasing in listeners and readers

Just as the false comma in this sentence, shows punctuation can influence sentence processing considerably. Pauses and other prosodic cues in spoken language serve the same function of structuring the sentence in smaller phrases. However, surprisingly little effort has been spent on the question as to whether both phenomena rest on the same mechanism and whether they are equally efficient in guiding parsing decisions. In a recent study, we showed that auditory speech boundaries evoke a specific positive shift in the listeners' event-related brain potentials (ERPs) that indicates the sentence segmentation and resulting changes in the understanding of the utterance (Steinhauer et al., 1999a). Here, we present three ERP reading experiments demonstrating that the human brain processes commas in a similar manner and that comma perception depends crucially on the reader's individual punctuation habits. Main results of the study are: (1) Commas can determine initial parsing as efficiently as speech boundaries because they trigger the same prosodic phrasing covertly, although phonological representations seem to be activated to a lesser extent. (2) Independent of the input modality, this phrasing is reflected online by the same ERP component, namely the Closure Positive Shift (CPS). (3) Both behavioral and ERP data suggest that comma processing varies with the readers' idiosyncratic punctuation habits. (4) A combined auditory and visual ERP experiment shows that the CPS is also elicited both by delexicalized prosody and while subjects replicate prosodic boundaries during silent reading. (5) A comma-induced reversed garden path turned out to be much more difficult than the classical garden path. Implications for psycholinguistic models and future ERP research are discussed.     

家庭功能对青少年冒险行为的影响:自我控制能力与不良同伴交往的序列中介效应

采用问卷法对922名中学生进行调查,考察了家庭功能与青少年冒险行为的关系以及自我控制能力、不良同伴交往的中介作用。结果发现:(1)家庭功能、自我控制能力、不良同伴交往和冒险行为两两之间相关显著;(2)自我控制能力在家庭功能与青少年冒险行为之间起中介作用;(3)自我控制能力和不良同伴交往在家庭功能和青少年冒险行为之间构成序列中介,家庭功能对青少年冒险行为的影响主要通过家庭功能——自我控制能力——不良同伴交往——冒险行为这一路径实现。研究结果进一步揭示了家庭、同伴和个体自身因素影响青少年冒险行为的内在机制。     

关系自我和集体自我在自我建构中的层级关系

三重自我建构认为,自我包含三个方面：个体自我,关系自我和集体自我。个体自我的核心地位已经得到诸多研究的证实,但关系自我和集体自我的层级关系还缺乏定论。越重要的自我,与积极信息的联系越紧密,以达到维持自尊、抵御自我威胁的目的。因此,采用内隐联想范式（IAT）验证对两种自我的积极联想,并对比两者积极联想程度以确定其层级关系。结果发现,相比非自我信息,被试对关系自我和集体自我均存在内隐的积极联想,从内隐的层面证实了关系自我和集体自我的存在。相比关系自我,被试对集体自我存在更强的积极联结,自我建构中的集体自我在内隐层面占据更为重要的位置。     

初中生学生投入的发展特点及其与同伴欺负的关系:一项三年追踪研究

采用问卷法和追踪研究设计,对北京市294名初一学生进行了连续三年的追踪测查,来考察初中生学生投入的发展特点,以及同伴欺负与学生投入发展变化的关系。运用多层线性模型进行数据分析,结果表明：（1）从初一（T1）到初三（T3）,学生的行为投入呈下降趋势（主要集中在参与学校活动的投入度上）,情感投入和认知投入呈上升趋势;（2）在控制性别和父母学历后,初中生受言语欺负会负向预测T1时的行为和情感投入;受关系欺负会负向预测T1时的行为、情感及认知投入;受身体欺负会负向预测行为投入的下降速度。     

朋友圈点赞与主观幸福感的关系:一个有中介的调节模型

研究旨在考察社交网站（微信朋友圈）中的积极反馈（点赞）与个体主观幸福感的关系,及其内在作用机制—孤独感的中介效应和生命意义体验的调节效应。采用朋友圈点赞频率问卷、生命意义体验量表、孤独感量表和主观幸福感量表对461名微信使用者进行研究。结果表明：（1）个体在朋友圈中获得点赞的频率可正向预测其主观幸福感。（2）生命意义体验对点赞频率与主观幸福感之间的关系具有调节效应。（3）这种调节效应以孤独感为中介变量。研究揭示了社交网站中的积极反馈与个体主观幸福感之间关系的内在机制及其个体差异,对避免社交网站中社会反馈的消极影响具有理论意义。     

对高血压诊治的现象与本质的关系反思——聚焦血压变化与心脑肾血液灌注量的关系

高血压和低血压都存在急性状态和慢性状态,在急性状态,高血压表现为血流高灌注,低血压表现为血流低灌注;而在慢性状态,高血压和低血压则表现出共同的特点——血流低灌注。血压数值只是个表面现象,重要的是透过血压数值的变化去探究血压变化背后的病理生理改变,尤其是血压变化与重要脏器血液灌注量多少的关系,治疗的最终目的是维持人体脏腑器官一定的血流量,而不是仅仅满足于发现并治疗患者所表现出来的血压数值。
