儿童的孤独感及与同伴交往的关系

孤独感是当一个人的社会关系网络比预期的更小或更不满意时产生的一种不愉快的情绪体验,儿童长期处于此状态会导致适应不良。孤独感的社交需要理论认为孤独感是对社交需要未满足的反应,强调孤独感的情感或感受层面;认知加工观主张孤独感的产生是因为个体对觉知到的人际关系现状不满意,强调孤独感的认知成分。同伴交往4个水平上的变量会影响到孤独感的产生,而孤独感作为一种消极的情绪体验,也会对同伴交往产生不良影响。未来研究应该多从家庭功能与同伴交往相结合的角度探讨孤独感的产生机制,对孤独儿童的干预研究也有待开展     

Listenmee® and Listenmee® smartphone application: Synchronizing walking to rhythmic auditory cues to improve gait in Parkinson’s disease

Evidence supports the use of rhythmic external auditory signals to improve gait in PD patients (Arias & Cudeiro, 2008; Kenyon & Thaut, 2000; McIntosh, Rice & Thaut, 1994; McIntosh et al., 1997; Morris, Iansek, & Matyas, 1994; Thaut, McIntosh, & Rice, 1997; Suteerawattananon, Morris, Etnyre, Jankovic, & Protas , 2004; Willems, Nieuwboer, Chavert, & Desloovere, 2006). However, few prototypes are available for daily use, and to our knowledge, none utilize a smartphone application allowing individualized sounds and cadence. Therefore, we analyzed the effects on gait of Listenmee®, an intelligent glasses system with a portable auditory device, and present its smartphone application, the Listenmee app®, offering over 100 different sounds and an adjustable metronome to individualize the cueing rate as well as its smartwatch with accelerometer to detect magnitude and direction of the proper acceleration, track calorie count, sleep patterns, steps count and daily distances. The present study included patients with idiopathic PD presented gait disturbances including freezing. Auditory rhythmic cues were delivered through Listenmee®. Performance was analyzed in a motion and gait analysis laboratory. The results revealed significant improvements in gait performance over three major dependent variables: walking speed in 38.1%, cadence in 28.1% and stride length in 44.5%. Our findings suggest that auditory cueing through Listenmee® may significantly enhance gait performance. Further studies are needed to elucidate the potential role and maximize the benefits of these portable devices.     

Self-unawareness of levodopa induced dyskinesias in patients with Parkinson’s disease

The study analyzes the presence of dyskinesias-reduced-self-awareness in forty-eight patients suffering from Parkinson’s disease (PD). As the association with executive dysfunction is a matter of debate and we hypothesize it plays an important role in dyskinesias self-unawareness, we analyzed the role of dopaminergic treatment on the medial-prefrontal-ventral-striatal circuitry using a neurocognitive approach. Special attention was given to metacognitive abilities related to action-monitoring that represent a novel explanation of the phenomenon.PD patients were assessed using different rating scales that we devised to measure movement awareness disorders. In order to ascertain whether each variable measured at a cognitive-clinical level contributes to predicting the scores of the movement-disorder-awareness-scales, we conducted multiple logistic regression models using the latter as binary dependent variables. We used the Wisconsin Card Sorting Test-metacognitive-version to assess the executive functions of the prefrontal-ventral-striatal circuitry.Data showed that a reduction of self-awareness using the Dyskinesia rating scale was associated with global monitoring (p = .04), monitoring resolution (p = .04) and control sensitivity (p = .04). Patients failed to perceive their performance, distinguish between correct and incorrect sorts, be confident in their choice and consequently decide to gamble during the task.We did not find any association with executive functions using the hypo-bradykinesia rating scale.Our findings indicate that when the comparator mechanism for monitoring attentive performance is compromised at a prefrontal striatal level, patients lose the ability to recognize their motor disturbances that do not achieve conscious awareness.     

Rethinking deindustrialisation and male career crisis

The decline in manufacturing and growth of service-based jobs has prompted many social theorists to argue that the ability of working-class men to construct meaningful and rewarding careers is becoming ever more limited. Despite using the universal label ‘working class’, the experience of skilled working-class men has been largely ignored. This article explores 26 work history interviews collected from 14 former Royal Dockyard tradesmen in South-East England and 12 of these men's sons and grandsons. Findings from this research challenge the idea that most men were/and are passive victims of industrial change. By contrast, the majority of men in this study managed to carefully adapt to and navigate the transition from industrial to post-industrial work whilst still retaining a ‘linear life narrative’ to give meaning to their evolving careers and lives.     

Motor planning in Parkinson’s disease patients experiencing freezing of gait: The influence of cognitive load when approaching obstacles

Freezing of gait (FOG) in Parkinson’s disease (PD) is typically assumed to be a pure motor deficit, although it is important to consider how an abrupt loss of gait automaticity might be associated with an overloaded central resource capacity. If resource capacity limits are a factor underlying FOG, then obstacle crossing may be particularly sensitive to dual task effects in eliciting FOG. Participants performed a dual task (auditory digit monitoring) in order to increase cognitive load during obstacle crossing. Forty-two non-demented participants (14 PD patients with FOG, 13 PD who do not freeze, and 14 age-matched healthy control participants) were required to walk and step over a horizontal obstacle set at 15% of the participants’ height. Kinematic data were split into two phases of their approach: early (farthest away from the obstacle), and late (just prior to the obstacle). Interestingly, step length variability and step time variability increased when PD patients with FOG performed the dual task, but only in the late phase prior to the obstacle (i.e. when closest to the obstacle). Additionally, immediately after crossing, freezers landed the lead foot abnormally close to the obstacle regardless of dual task condition, and also contacted the obstacle more frequently (planning errors). Strength of the dual task effect was associated with low general cognitive status, declined executive function, and inappropriate spatial planning, but only in the PD-FOG group. This study is the first to demonstrate that cognitive load differentially impacts planning of the final steps needed to avoid an obstacle in PD patients with freezing, but not non-freezers or healthy controls, suggesting specific neural networks associated with FOG behaviours.     

Anglicans and Islam in East Africa: The Diocese of Zanzibar and the Universities’ Mission to Central Africa (1923–63)

This article examines the legacy of Godfrey Dale, who in 1923 published a Qur'an in Swahili, with the intention of letting people “know what the Qur?ān does say.” The work of his successors is explored. It discusses the proposals for work amongst Muslims submitted by lay and ordained members of the Diocese of Zanzibar for consideration at the 1944 Diocesan Conference, as the Diocese prepared for the situation after World War II. Finally, it examines the role of the Diocese with particular reference to Christian–Muslim relations as Tanganyika and Zanzibar prepared for Independence.     

Affaire Vincent L. : les maux de la fin

As called back it June 24th, Council of State in its press release, the Vincent L.’s case “raise scientific, ethical and human questions”. At first, to decide on the fate of this 38-year-old man, the administrative jurisdiction recovered from it in expert opinions asked to establish the existence or not of an unreasonable stubbornness. But the objectivity of the medical science cannot solve only this litigation where the outcome is the life or the death of a patient. That is why the court opened its doors to the ethical speech too. If in this case, the science could not exist without consciousness, if the legal word could not exist without the ethical word, it's because of the human dimension which fills this media and legal affair. So behind this patient's case, called now “the Vincent L.’s affair”, it's a question about the death, that of a young man in the incapacity to express its will. It's also a question of a family disagreement on the future of their son, brother, or husband. In this context, “politically and mediatically charged”, the administrative jurisdiction pronounced four times on the decision of the stop of Vincent L.’s treatment. The educational position of the French judges allowed to clear up statutory provisions of the Leonetti's act.     

Power,empowerment and surrender in the context of paediatric spiritual care

The dynamics of ‘surrender’ is here put in dialectic with the dynamics of ‘power’ observed in situation involving children and their caregivers in a paediatric hospital setting. Following a qualitative research method used in practical theology, three case studies are presented and then interpreted in the light of both social sciences and Christian theology/spirituality. In the power/surrender paradox, there will always be a need for discernment for each situation and each encounter if the caregiver wants to better care for the children and continue to acknowledge their contribution to the life experience and wisdom of adults. Power and surrender both need to be embraced in order to grow in a fruitful spiritual life.     

The effect of autonomous and controlled motives on eating dysregulation: Implications for individuals classified as underweight,overweight or obese

IntroductionControlled and autonomous motivational factors from self-determination theory have previously been highlighted as key factors in eating regulation. The present study examined controlled motives as an overarching motivational factor in eating dysregulation and examined its effects on dieting behaviour for those who are underweight, overweight or obese.ObjectiveTo examine whether the influence of controlled motives on dieting behaviour would be moderated by body mass index (BMI). Specifically, it was hypothesised that controlled motives would be associated with high levels of dieting behaviour in underweight individuals and low levels of dieting behaviour in individuals classified as overweight or obese.MethodOne hundred and thirty-seven participants completed the measures of height, weight, and motivation and intentions towards watching their diet and subsequently completed a measure of dieting behaviour two weeks later.ResultsModerated regression and simple slopes analyses provided support for the hypothesised effects at underweight, overweight, and obese range BMIs.ConclusionThe effect of controlled motives on dieting behaviour is dependent upon BMI and therefore varies across underweight, overweight, and obese individuals. The implications of controlled motives and external pressures to watch one's diet are discussed.     

When implicit fails: Explicit but not implicit attitudes predict choices of decided and undecided voters

IntroductionA recent study (Friese et al., 2012) involving two major political elections in the US and Germany reported that voting behavior was better predicted by explicit than implicit attitudes for both decided and undecided voters and that when voting behavior was predicted by implicit attitudes, the prediction was better for decided than undecided voters.ObjectiveWe conducted a comparable study for the 2012 French presidential election using voter volatility as a measure of voter decidedness, in order to test the generalizability of the findings of Friese et al. (2012).MethodParticipants’ voting intention, explicit and implicit attitudes towards the candidates Sarkozy and Hollande were collected during the 2 weeks separating the two rounds of the election.ResultsOur findings confirm that explicit attitudes outperform implicit attitudes when predicting voting choice, but not that the relationship between implicit attitudes and voting intention is moderated by voter decidedness.ConclusionFurther research is needed in order to test whether the moderation of implicit attitudes by voter decidedness is a robust finding or not.
