Patients with non-specific low back pain, or a similar disorder, may stiffen their trunk, which probably alters their walking coordination. To study the direct effects of increasing trunk stiffness, we experimentally increased trunk stiffness during walking, and compared the results with what is known from the literature about gait coordination with, e.g., low back pain. Healthy subjects walked on a treadmill at 3 speeds (0.5, 1.0 and 1.5 m/s), in three conditions (normal, while contracting their abdominal muscles, or wearing an orthopedic brace that limits trunk motions). Kinematics of the legs, thorax and pelvis were recorded, and relative Fourier phases and amplitudes of segment motions were calculated. Increasing trunk stiffness led to a lower thorax–pelvis relative phase, with both a decrease in thorax–leg relative phase, and an increase in pelvis–leg relative phase, as well as reduced rotational amplitude of thorax relative to pelvis. While lower thorax–pelvis relative phase was also found in patients with low back pain, higher pelvis–leg relative phase has never been reported in patients with low back pain or related disorders. These results suggest that increasing trunk stiffness in healthy subjects causes short-term gait coordination changes which are different from those seen in patients with back pain.  相似文献

The “Dark Triad” of Machiavellianism, Narcissism, and psychopathy has received much research attention since the seminal article of Paulhus and Williams (2002). The introduction of the Dark Triad came shortly after the discovery of a six-dimensional model of personality characteristics, now called the HEXACO model. One of the HEXACO factors—Honesty–Humility—is essentially equivalent (at its opposite pole) to the common element shared by the Dark Triad variables. We suggest that the emergence and popularity of the Dark Triad reflect the importance of these characteristics and their underrepresentation in five-dimensional models of personality. We note that optimal prediction and understanding of criterion variables is better achieved using the HEXACO factors than using an ad hoc combination of the Big Five and a Dark Triad composite.  相似文献

Life history as applied to human psychology has progressed on different levels of analysis including between racial groups (Differential-K) and between individuals (Life History Theory). While the approaches at each level have garnered significant research support, some findings at the level of individual differences are inconsistent with findings from the level of group differences. The association between the General Factor of Personality and general intelligence was examined across and within racial groups to investigate the inconsistency. The results were in line with predictions derived from strategic differentiation–integration effort (SD–IE), the proposition that aggregation amongst variables decreases as life history strategy slows. The results suggest SD–IE may be a useful tool in reconciling the apparent contradictions across the levels of analysis.  相似文献

The concept of personality disorders (PDs) is shifting from categorical to dimensional, conceptualizing PDs as maladaptive variants of basic personality traits. The Agreeableness trait in the Five Factor Model of personality classically represents dispositional cooperativeness, which is associated with PDs characterized by interpersonal impairments. However, recent research designates two separate dispositional tendencies: active and reactive cooperativeness. Using the HEXACO model of personality we assessed traits representing these tendencies (Honesty–Humility and Agreeableness) and investigated their relation to Borderline features in 602 individuals. Borderline features were associated with low Agreeableness scores, representing low reactive cooperation, entailing a tendency to retaliate. Yet, there was no association with Honesty–Humility, implying intact active cooperativeness and non-exploitation. These findings extend prior results on the relation between Borderline PD and basic personality dimensions driving prosocial behavior. Implications for the understanding of interpersonal problems in PDs and the refinement of existing therapies are discussed.  相似文献

Many studies have reported meditation training has beneficial effects on brain structure and function. However, very little is known about meditation-induced changes in brain complex networks. We used network analysis of electroencephalography theta activity data at rest before and after 1-week of integrative body–mind training (IBMT) and relaxation training. The results demonstrated the IBMT group (but not the relaxation group) exhibited significantly smaller average path length and larger clustering coefficient of the entire network and two midline electrode nodes (Fz and Pz) after training, indicating enhanced capacity of local specialization and global information integration in the brain. The findings provide the evidence for meditation-induced network plasticity and suggest that IBMT might be helpful for alterations in brain networks.  相似文献

Teacher–child relationship building (TCRB) is a play-based professional development programme adapted from kinder training and filial therapy. Intended for early education teachers and students, TCRB is designed to strengthen the teacher–child relationship, improve student behaviour, enhance academic involvement and develop teachers' classroom management skills. In the current study, we utilised a phenomenological approach to examine teachers' perceptions of the initial implementation of TCRB through identifying individual and collective perspectives in the summation of themes. Findings indicated that the teachers perceived the TCRB model to be informative, well organised, appropriately structured and effective in enhancing teacher–child relationships, improving classroom management skills and reducing behavioural problems among child participants. Limitations of the study, implications and suggestions for future research are discussed.  相似文献

While salespeople use adaptive influence tactics in interactions with consumers, consumers can act as goal-oriented individuals attempting to manage those interactions. Prior research has documented a repertoire of consumer response behaviours, but little is known about the motivational forces. The present research examines the effects of regulatory focus on consumer behavioural tendencies in response to personal selling attempts. The findings suggest that the more promotion-focused consumers are more likely to engage in goal-seeking behaviours. This research not only addresses a void in the literature, but more importantly, sheds light on motivational antecedents driving consumer behaviours in customer–salesperson interactions.  相似文献

The interplay of religion and politics has been a consistent theme within the literature of political radicalism and religious violence in the contemporary Muslim world. Indonesia, which has long paraded its multi-layered history of religions, recently emerged as one of the main sites of Muslim–Christian violence. The religious volatility that has characterized Indonesia over the past decade has, however, left variations in vitality between faith-based organizations under-researched. In order to examine how the Christian churches undergird their institutions in the world's largest Muslim country, this article takes as its case study Salib Putih (White Cross) in the Javanese city of Salatiga and traces how a legal issue comes to transcend the boundary between religion and politics at local and national levels.  相似文献

This article describes and analyses the changes that have occurred in the services performed by chaplains in the Israel Defense Force (IDF) – the only military in the world that consists almost entirely of Jews. Essentially, we argue, the shift has been one of focus. For many years, IDF chaplains primarily (albeit never exclusively) concerned themselves with providing religious services to the minority of personnel who observed Orthodox Jewish rituals. ‘Outreach’ programmes, targeted at the secular Jewish majority, were secondary. Recently, however, the IDF rabbinate has undergone a process of ‘role expansion’, emphasising the provision of counselling and guidance to the entire Jewish complement, especially in combat units. In the second part of the article, we analyse the possible reasons for that development: demographic and cultural trends in Israeli society; the prominence of counter-insurgency missions in the IDF’s operational agenda; and the personalities of recent chief chaplains. Finally, we address the possible implications of this shift, asking whether the intra-organisational frictions that it generates, especially with the Education Corps, portends a battle for the soul of the IDF.  相似文献

β-cyclodextrin glucosyltransferase (β-CGTase) is an essential enzyme to catalyse the biotransformation of starch into β-cyclodextrins (β-CD). β-CD has widespread applications in the biomedical, pharmaceutical and food industries. The present study focused on β-CGTase production using an efficient natural microbial strain and statistical production optimization for enhanced production. The isolated organism Bacillus sp. NCIM 5799 was found to be 5 μm short bacilli under FE-SEM and alkalihalophilic in nature. The β-CGTase production was optimized using a combination of Plackett–Burman design (PBD) and Central Composite Design—Response Surface Methodology (CCD-RSM). On PBD screening Na2CO3, peptone and MgSO4.7H2O were found to be significant for optimal β-CGTase production, whereas the soluble starch and K2HPO4 concentrations were found to be nonsignificant for β-CGTase production. The significant factors obtained after PBD were further optimized using CCD-RSM design. Peptone was found to have a significant interaction effect with Na2CO3, and MgSO4·7H2O and Na2CO3 exhibited a significant effect on the production of CGTase. The production of β-CGTase was enhanced in the presence of peptone (3%) and Na2CO3 (0·8%). CGTase production obtained was 156·76 U/ml when optimized using CCD-RSM. The final optimized medium (RSM) shows 7·7- and 5·4-fold high productions as compared to un-optimized and one factor at a time production media.  相似文献
