Current trends in employee assistance concerns : employee assistance professionals\u27 reports on the presenting concerns of employees

This study explored current trends in the most commonly presented areas of concern Employee Assistance (EA) professionals observed among their clients. It is important to understand a comprehensive view of the state of current issues in the field as well as the individual in context and the role work plays in individuals\u27 lives; from providing a source of income to a sense of self. A nonprobability expert sample of 111 EA professionals was recruited through participants\u27 membership in professional organizations and a web-based group related to the field. Participants held master\u27s level certification or greater in mental health-related fields, were certified in the EA field (CEAP), and currently provided EA services. Participants took part in a quantitative online survey and were given an opportunity to participate further in brief follow-up phone or email interviews. Research found Stress-related concerns, Mental health, and Marital concerns to be the top three concerns seen among EA clients. The effects of these issues among our workforce can be widespread (e.g., physical health impacts) and costly (e.g., insurance increases). The findings of this study were both significant and representative of the EA field. Identifying the prevalence of these concerns is of major importance to providers and organizations who need this information to allocate resources for providing services and indicates the importance of having trained professionals available to assist individuals. This study\u27s findings also defend the position that mental health issues should achieve the same status (parity) physical health issues currently hold with regard to insurance benefits

Wind tunnel and numerical study of a small vertical axis wind turbine

This paper presents a combined experimental and computational study into the aerodynamics and performance of a small scale vertical axis wind turbine (VAWT). Wind tunnel tests were carried out to ascertain overall performance of the turbine and two- and three-dimensional unsteady computational fluid dynamics (CFD) models were generated to help understand the aerodynamics of this performance. Wind tunnel performance results are presented for cases of different wind velocity, tip-speed ratio and solidity as well as rotor blade surface finish. It is shown experimentally that the surface toughness on the turbine rotor blades has a significant effect on performance. Below a critical wind speed (Reynolds number of 30,000) the performance of the turbine is degraded by a smooth rotor surface finish but above the turbine performance is enhanced by a smooth surface finish. Both two bladed and three bladed it, rotors were tested and a significant increase in performance coefficient is observed for the higher solidity rotors (three bladed rotors) over most of the operating range. Dynamic stalling behaviour and the resulting large and rapid changes in force coefficients and the rotor torque are shown to be the likely cause of changes to rotor pitch angle that occurred during early testing. This small change in pitch angle caused significant decreases in performance. The performance coefficient predicted by the two dimensional computational model is significantly higher than that of the experimental and the three-dimensional CFD model. The predictions show that the presence of the over tip vortices in the 3D simulations is responsible for producing the large difference in efficiency compared to the 2D predictions. The dynamic behaviour of the over tip vortex as a rotor blade rotates through each revolution is also explored in the paper. (C) 2009 Elsevier Ltd. All rights reserved

Using body language indicators for assessing the effects of soundscape quality on individuals

“Sounding Brighton” is a collaborative project exploring practical approaches towards better soundscapes focusing on soundscape issues related to health, quality of life and restorative functions of the environment. The project is part of a citywide engagement process working to provide opportunities to demonstrate how an applied soundscape approach might: tackle conventional noise problems, contribute to local planning and improve the environment in areas including urban green spaces, the built environment and traffic noise. So far, a soundscape map of the city has been developed, and a public outreach exhibition and conferences have taken place. One preliminary, experimental soundscape intervention in night noise has been analysed. This paper reports on further work to develop a better understanding of the effects of soundscapes on individual and community responses to soundscape through the use of body language indicators. Two-minute excerpts of aversive and preferred music were presented to 11 healthy volunteers in a motion-capture laboratory setting. Their responses were quantified computationally using motion-capture-derived parameters for position, absolute movement speed, and stillness. The prevalence of stillness of the head height (based on a 2 cm cut-off during 2-second sectors) was significantly lower when volunteers were exposed to unpleasant music compared to preferred music. This experiment provides proof in principle that changes in soundscape can be associated with subsequent, objective and statistically significant changes in body language that can be detected computationally

What does not happen: quantifying embodied engagement using NIMI and self-adaptors

Previous research into the quantification of embodied intellectual and emotional engagement using non-verbal movement parameters has not yielded consistent results across different studies. Our research introduces NIMI (Non-Instrumental Movement Inhibition) as an alternative parameter. We propose that the absence of certain types of possible movements can be a more holistic proxy for cognitive engagement with media (in seated persons) than searching for the presence of other movements. Rather than analyzing total movement as an indicator of engagement, our research team distinguishes between instrumental movements (i.e. physical movement serving a direct purpose in the given situation) and non-instrumental movements, and investigates them in the context of the narrative rhythm of the stimulus. We demonstrate that NIMI occurs by showing viewers’ movement levels entrained (i.e. synchronised) to the repeating narrative rhythm of a timed computer-presented quiz. Finally, we discuss the role of objective metrics of engagement in future context-aware analysis of human behaviour in audience research, interactive media and responsive system and interface design

Multi-segment kinematic model to assess three-dimensional movement of the spine and back during gait.

BACKGROUND Relatively little is known about spine during gait compared to movement analysis of the lower extremities. The trunk is often regarded and analysed as a single rigid segment and there is a paucity of information on inter-segmental movement within the spine and its relationship to pelvis and lower limbs. OBJECTIVES To develop and validate a new multi-segment kinematic model to assess regional three-dimensional movement of the lumbar, lower thoracic and upper thoracic spine during gait. STUDY DESIGN Observational study. METHODS The study was conducted in two parts: (1) to provide validation measures on the kinematic model built in commercially available software and (2) to apply the marker configuration to the spine at T3, T8 and L3 during gait analysis on 10 healthy male volunteers. RESULTS Proposed model revealed excellent concurrent validation measures between an applied input angle to the recorded output angle from the kinematic model. A high reliability was observed during gait analysis, both during a single session and between sessions for all participants. CONCLUSION The thoracic region of the spine should not be modelled as a single rigid segment and the proposed three-dimensional cluster is reliable and repeatable to assess the inter-segmental movement of the spine. CLINICAL RELEVANCE Reliable kinematic data can be collected using the three-dimensional cluster technique, thus, allowing researchers to accurately distinguish between movement patterns of healthy individuals to those with a clinical condition, and provide confidence in data acquisition during the monitoring process of an implemented rehabilitation intervention programme

Aggressive Behaviour of Metastatic Melanoma in a Patient with Neurofibromatosis Type 1

Malignant melanoma is a common skin neoplasm bearing poor prognosis when presenting with metastases. Rarely melanoma metastases present without an identifiable primary cutaneous lesion despite exhaustive workup. We describe the case of a solitary lung metastasis in a patient with neurofibromatosis type 1 without an identifiable primary tumour. The rapid progression of this malignant neoplasm that led to the patient’s death within 1 year is described

Porous silica spheres as indoor air pollutant scavengers

Porous silica spheres were investigated for their effectiveness in removing typical indoor air pollutants, such as aromatic and carbonyl-containing volatile organic compounds (VOCs), and compared to the commercially available polymer styrene-divinylbenzene (XAD-4). The silica spheres and the XAD-4 resin were coated on denuder sampling devices and their adsorption efficiencies for volatile organic compounds evaluated using an indoor air simulation chamber. Real indoor sampling was also undertaken to evaluate the affinity of the silica adsorbents for a variety of indoor VOCs. The silica sphere adsorbents were found to have a high affinity for polar carbonyls and found to be more efficient than the XAD-4 resin at adsorbing carbonyls in an indoor environment
