Martin Grimmer, Matthew Holgate, Jeffrey Ward, Alexander Boehler, Andre Seyfarth
Passive prosthetic feet are not able to provide non-amputee kinematics and kinetics for the ankle joint. Persons with amputations show reduced interlimb symmetry, slower walking speeds, and increased walking effort. To improve ankle range of motion and push off, various powered prosthetic feet were introduced. This feasibility study analyzed if predefined motor reference trajectories can be used to achieve non-amputee ankle biomechanics during walking with the powered prosthetic foot, Walk-Run Ankle. Trajectories were calculated using the desired ankle angle and ankle moment based spring deflection at a given spring stiffness...

This paper presents two different strategies for difficulty adaptation in a competitive arm rehabilitation game: a manual adaptation strategy and an automatic performance-based adaptation strategy. The two strategies were implemented in a competitive game controlled with an inertial-sensor-based home rehabilitation device. They were first evaluated with 32 pairs of unimpaired participants, who played the game with manual adaptation, automated adaptation, or no adaptation. Each variant was played for 9 minutes...

Minsu Chang, Yeongmin Kim, Yoseph Lee, Doyoung Jeon
This paper proposes a method of detecting the postural stability of a person wearing the lower limb exoskeletal robot with the HAT(Head-Arm-Trunk) model. Previous studies have shown that the human posture is stable when the CoM(Center of Mass) of the human body is placed on the BoS(Base of Support). In the case of the lower limb exoskeletal robot, the motion data, which are used for the CoM estimation, are acquired by sensors in the robot. The upper body, however, does not have sensors in each segment so that it may cause the error of the CoM estimation...

People with trunk impairment cannot lean forward because of the dysfunction of the trunk resulting from events such as cervical cord injury (CCI). It is therefore difficult for such people to work at a table because they may easily fall from their wheelchair, and it is also hard for them to return to their original position. This limits the activities of daily living (ADLs) of people with trunk impairment. These problems can be solved to some extent with equipment such as a wheelchair belt or a spinal orthosis that can help the person to maintain his or her posture...

Some unilateral lower-limb amputees load the intact limb more than the prosthetic limb. This can cause chronic pains, fatigue, lumbago, and joint diseases, including knee osteoarthritis. To avoid and counteract these symptoms it is necessary to improve their asymmetric gait. Increasing the function of the hip abductor muscle is important to maintaining symmetrical weight distribution. Therefore, the purpose of this study is to develop a training assist system, which estimates and visualizes an abductor muscle by using a color-depth sensor...

REVIEW
Ross Roberts, Tim Woodman
In this review, we examine the literature in relation to personality and performance. Much of the extant work in this area has focused on the role of the Big 5 traits (i.e., extraversion, conscientiousness, openness to experience, agreeableness, and neuroticism), at the expense of other personality variables that have a strong performance-focused rationale. Further, a focus on main effects has dominated the literature, without recourse to consider person×environment interactions. In this review we go beyond the Big 5 and consider the role of two personality traits, narcissism and alexithymia, in relation to performance...

REVIEW
Ariel J Lang
In recent years, the field has witnessed considerable enthusiasm for the ancient practice of mindfulness. The skills derived from this experience, including focused attention, nonjudgmental acceptance of internal experiences and reduced autonomic reactivity, may be helpful in counteracting pathological responses to trauma. Several types of interventions that incorporate principles of mindfulness have been examined for treatment of posttraumatic stress disorder (PTSD). This nascent literature is inconsistent and methodologically limited but does suggest that mindfulness is a potentially important tool for creating psychological change...

REVIEW
Rena Repetti, Shu-Wen Wang
In the short-term, daily job stressors influence family interactions through their impact on the employed person's mood, thoughts, and coping behaviors. In the long-term, family relationships can be shaped by those experiences in both positive and negative ways. Some spouse 'cross-over' effects appear to represent accommodations of the employed partner under stress-for instance, a spouse's increased provision of social support and involvement with children-and are evidence of dynamics that go beyond a simple and direct transfer of stress from work to home...

BACKGROUND: In early 1990s, Tanzania like other African countries, adopted health sector reform (HSR). The most strongly held centralisation system that informed the nature of services provision including health was, thus, disintegrated giving rise to decentralisation system. It was within the realm of HSR process, user fees were introduced in the health sector. Along with user fees, various types of health insurances, including the Community Health Fund (CHF), were introduced. While the country's level of enrolment in the CHF is low, there are marked variations among districts...

Increases in incidents involving so-called confused persons have brought attention to the potential costs of recent changes to public mental health (PMH) services in the Netherlands. Decentralized under the (Community) Participation Act (2014), local governments must find resources to compensate for reduced central funding to such services or "innovate." But innovation, even when pressure for change is intense, is difficult. This perspective paper describes experience during and after an investigation into a particularly violent incident and murder...

We investigate prosthetic eye wearers' initial and current concerns about mucoid discharge, visual perception, and appearance, and the reasons for their concerns. A retrospective, cross-sectional study of private practice patients was designed. Participants were 217 experienced prosthetic eye wearers, aged at least 16 years. An anonymous questionnaire was e-mailed or mailed to participants. Descriptive and inferential statistics were used to investigate differences or correlations between variables. Content analysis was used to analyze participants' open responses...

In this chapter, we introduce a new area of social pharmacology that encompasses the study of the role of neuromodulators in modulating a wide range of social behaviors and brain function, with the interplay of genetic and epigenetic factors. There are increasing evidences for the role of the neuropeptide oxytocin in modulating a wide range of social behaviors, in reducing anxiety, and in impacting the social brain network. Oxytocin also promotes social functions in patients with neuropsychiatric disorders, such as autism and reduces anxiety and fear in anxiety disorders...

Borderline personality disorder (BPD) is a prevalent and severe mental disorder with affect dysregulation, impulsivity, and interpersonal dysfunction as its core features. Up to now, six studies have been performed to investigate the role of oxytocin in the pathogenesis of BPD. While a beneficial effect of oxytocin on threat processing and stress responsiveness was found, other studies using an oxytocin challenge design presented with rather heterogeneous results. Future studies have to include a sufficiently large sample of patients, control for gender, and focus on mechanisms known to be related to aversive early life experiences...

The neuropeptide oxytocin (OT) has emerged as a potent modulator of diverse aspects of interpersonal relationships. OT appears to work in close interaction with several other neurotransmitter networks, including the dopaminergic reward circuit, and to be dependent on sex-specific hormonal influences. In this chapter, we focus on four main domains of OT and interpersonal relationships, including (1) the protective effect of OT on an individual's ability to withstand stress (i.e., stress buffering), (2) the effect of OT on emotion recognition and empathy, (3) OT's ability to enhance social synchrony and cooperation among individuals, and (4) the effect of OT on an individual's perception of social touch...

Phishing is a fraudulent form of email that solicits personal or financial information from the recipient, such as a password, username, or social security or bank account number. The scammer may use the illicitly obtained information to steal the victim's money or identity or sell the information to another party. The direct costs of phishing on consumers are exceptionally high and have risen substantially over the past 12 years. Phishing experiments that simulate real world conditions can provide cybersecurity experts with valuable knowledge they can use to develop effective countermeasures and prevent people from being duped by phishing emails...

Many stroke survivors with aphasia in the acute period experience spontaneous recovery within the first six months after the stroke. However, approximately 30-40% sustain permanent aphasia and the factors determining incomplete recovery are unclear. Suboptimal recovery may be influenced by disruption of areas seemingly spared by the stroke due to loss of white matter connectivity and network integrity. We reconstructed individual anatomical whole-brain connectomes from 90 left hemisphere stroke survivors using diffusion MR images...
